DETAILED DESCRIPTION OF THE EMBODIMENTS Hereinafter, some embodiments of the present disclosure will be clearly and completely described with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, but not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those ordinarily skilled in the art fall within the scope of protection of the present disclosure.
In related air conditioners, to improve the support performance of support feet for a main unit, a plurality of support feet are arranged to support the main unit. However, the complex connection structure between the support feet and the main unit leads to inconvenient mounting for the user and time consuming. Furthermore, the arrangement of support feet affects the aesthetic appeal of mounting of the main unit, reducing the usage experience of the user.
To solve the above problem, as shown in FIG. 1, an air conditioner provided by some embodiments of the present disclosure can include a housing 1. The housing 1 can be configured as a shell outside the air conditioner. The interior of the housing 1 can be used for providing a mounting space.
As shown in FIG. 1, in some embodiments, the housing 1 may be of a cuboid hollow structure. The length direction of the housing 1 can be set along the height direction, so that the air conditioner is disposed upright at the usage site, thereby increasing the height of the air conditioner and reducing the space occupied by the air conditioner.
It should be noted that in other embodiments, the appearance and shape of the housing 1 can be designed according to requirements, which is not limited herein.
As shown in FIG. 2, in some embodiments, the air conditioner can include a refrigerant circuit. The refrigerant circuit can include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end to end. A refrigerant flows circularly in the refrigerant circuit formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant cycle, the outdoor heat exchanger 22 and the indoor heat exchanger 23 may serve as a condenser and an evaporator, respectively, so that the refrigerant is evaporated in the evaporator to absorb heat and is condensed in the condenser to release heat, thereby enabling a refrigerating cycle or a heating cycle of the air conditioner to be executed.
Specifically, during the refrigerating cycle, the outdoor heat exchanger 22 may serve as the condenser, and the indoor heat exchanger 23 may serve as the evaporator. During the heating cycle, the outdoor heat exchanger 22 may serve as the evaporator, and the indoor heat exchanger 23 may serve as the condenser.
It should be noted that both the refrigerating cycle and the heating cycle include a series of processes involving compression, condensation, expansion, and evaporation, and supply the refrigerant to air that has been conditioned and undergone heat exchange.
The compressor 21 is used for compressing a refrigerant gas and discharging the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.
The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the ambient environment through the condensing process.
The evaporator evaporates the expanded refrigerant and makes the refrigerant gas in a low-temperature and low-pressure state return to the compressor 21. The evaporator can achieve the refrigerating effect by exchanging heat with the ambient environment by means of the latent heat of evaporation from the refrigerant.
During the whole cycle, the air conditioner can regulate the temperature of the indoor space, thereby improving the comfort level within the indoor space, and improving the usage experience of the user.
As shown in FIG. 2, in some embodiments, the air conditioner can include an outdoor fan assembly 3. The outdoor fan assembly 3 can be disposed opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used for introducing outdoor air into the housing 1 to exchange heat with the outdoor heat exchanger 22 to form a heat exchange air flow.
For example, during the refrigerating cycle, the outdoor heat exchanger 22 serves as the condenser, and the outdoor fan assembly 3 can draw external air and blow it to the outdoor heat exchanger 22 to dissipate heat from the outdoor heat exchanger 22 so as to decrease the temperature of the outdoor heat exchanger 22. During the heating cycle, the outdoor heat exchanger 22 serves as the evaporator, and the outdoor fan assembly 3 can draw external air and blow it to the outdoor heat exchanger 22 to heat the outdoor heat exchanger 22 so as to increase the temperature of the outdoor heat exchanger 22.
As shown in FIG. 2, in some embodiments, the air conditioner can include an indoor fan assembly 4. The indoor fan assembly 4 can be disposed opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used for introducing indoor air into the housing 1 to exchange heat with the indoor heat exchanger 23 to form a heat exchange air flow.
For example, during the refrigerating cycle, the indoor heat exchanger 23 serves as the evaporator, and the indoor fan assembly 4 can draw indoor air outside the housing 1 and blow it to the indoor heat exchanger 23 to exchange heat from the indoor heat exchanger 23 so as to decrease the temperature of air flowing through the indoor heat exchanger 23, and blow the temperature-decreased air back to the indoor space so as to decrease the indoor air temperature.
For another example, during the heating cycle, the indoor heat exchanger 23 serves as the condenser, and the outdoor fan assembly 3 can draw indoor air outside the housing 1 and blow it to the indoor heat exchanger 23 to exchange heat from the indoor heat exchanger 23 so as to increase the temperature of air flowing through the indoor heat exchanger 23, and blow the temperature-increased air back to the indoor space so as to increase the indoor air temperature.
As shown in FIG. 2, in some embodiments, the compressor 21, the outdoor heat exchanger 22, the outdoor fan assembly 3, the indoor heat exchanger 23, and the indoor fan assembly 4 can be respectively disposed within an accommodating space 10 inside the housing 1. In this way, the housing 1 can provide a covering protection effect and can prevent structural damage caused by external foreign object incursion or external force impact, thereby improving the structural reliability of the air conditioner and ensuring that the air conditioner can work normally.
As shown in FIG. 2, in some embodiments, the accommodating space 10 inside the housing 1 can include three layers of sub-spaces. The three layers of sub-spaces are respectively a first sub-space 110, a second sub-space 120, and a third sub-space 130 arranged in sequence from bottom to top. The compressor 21 can be disposed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 can be disposed in the second sub-space 120. The indoor heat exchanger 24 and the indoor fan assembly 4 can be disposed in the third sub-space 130. Thus, through the three layers of sub-spaces in sequence from bottom to top, the components such as the compressor 21, the outdoor heat exchanger 22, the outdoor fan assembly 3, the indoor heat exchanger 23, and the indoor fan assembly 4 can be arranged in a scattered manner at different height positions inside the housing 1, which is beneficial to improving the overall height of the air conditioner, reducing the width and thickness dimensions of the air conditioner, and reducing the space of the usage site occupied by the air conditioner.
As shown in FIG. 2 and FIG. 3, in some embodiments, the housing 1 can include a chassis 12. The chassis 12 can be disposed at the bottom of the housing 1. The accommodating space 10 of the housing 1 can be formed above the chassis 12. The accommodating space 10 can serve as a mounting space for other components of the air conditioner. The chassis 12 can be used for supporting other components of the air conditioner.
The chassis is shown in FIG. 2 and FIG. 3. In some embodiments, the housing 1 can include support feet 13. The support feet 13 can be disposed on the chassis 12. The support feet 13 can be used for increasing the contact area between the bottom of the housing 1 and the ground, thereby improving the reliability of supporting the air conditioner by the chassis 12, and improving the stability of the air conditioner.
As shown in FIG. 4 and FIG. 5, in some embodiments, a plurality of support feet 13 may be disposed. The plurality of support feet 13 are supported on the chassis 12, enhancing the support stability and reliability on the chassis 12.
For example, as shown in FIG. 5, four support feet 13 may be disposed. The four support feet 13 can be spliced end to end to form a polygonal annular structure. It should be noted that in other embodiments, the number of the support feet 13 may be 3, 5, etc., which is not limited herein.
As shown in FIG. 4 and FIG. 5, in other embodiments, two opposite ends of the plurality of support feet 13 can be sequentially spliced end to end and continuously arranged circumferentially around the periphery of the chassis 12. It should be noted that the plurality of support feet 13 continuously arranged around the periphery of the chassis 12 can form a closed annular structure.
Specifically, one end of two opposite ends of each support foot 13 can be spliced with one adjacent support foot 13, and the other end of two opposite ends of the support foot 13 can be spliced with another adjacent support foot 13, such that the two opposite ends of the plurality of support feet 13 can be sequentially spliced end to end to form a structure encircling and circumferentially arranged around the periphery of the chassis 12. By means of splicing the support feet 13 mutually into an encircling structure, compared with a single independent support foot 13 in existing structures, due to each support foot 13 having independent force reception being prone to shaking from uneven ground or external force action, in this technical solution the end-to-end spliced support feet 13 integrally present a support ring structure, not only enabling each support foot 13 to achieve uniform force distribution but also enhancing overall support strength, thereby preventing the stability from being affected due to the looseness of a single support foot 13.
As shown in FIG. 6, FIG. 7, and FIG. 8, in some embodiments, the two opposite ends of each support foot 13 can be a first end 1301 and a second end 1302, respectively. A clamping groove 1303 can be concavely formed in the first end 1301 of the support foot 13. A positioning portion 131 can be convexly disposed in the second end 1302 of the support foot 13. The positioning portion 131 can be in fit with the clamping groove 1303.
As shown in FIG. 5, the positioning portion 131 of the support foot 13 can be inserted into the clamping groove 1303 of an adjacent support foot 13 in an aligned manner, such that the second end 1302 of the support foot 13 is spliced with the first end 1301 of the adjacent support foot 13. The clamping groove 1303 of the support foot 13 can be inserted into the positioning portion 131 of another adjacent support foot 13 in an aligned manner, such that the first end 1301 of the support foot 13 is spliced with the second end 1302 of the another adjacent support foot 13.
Specifically, the first end 1301 and the second end 1302 of the support foot 13 are connected to a support foot 13, respectively. By inserting the positioning portion 131 of the support foot 13 into the clamping groove 1303 of an adjacent support foot 13, the positioning portion 131 is clamped in the clamping groove 1303, such that the second end 1302 of the support foot 13 is spliced with the first end 1301 of the adjacent support foot 13. By means of the corresponding clamped connection between the clamping groove 1303 of the support foot 13 and the positioning portion 131 of another corresponding adjacent support foot 13, the first end 1301 of the support foot 13 is spliced with the second end 1302 of the another adjacent support foot 13. Thus, by inserting the positioning portion 131 of the adjacent support foot 13 into the corresponding clamping groove 1303, the clamped splicing manner between the support feet 13 does not need to use tools for mounting and also reduces the mounting difficulty of the support feet 13, achieving simplification of the support structure of the chassis 12, and reducing the operation difficulty for the user. Further, after splicing is completed, the plurality of support feet 13 can form an encircling support structure, enabling each support foot 13 to achieve uniform force distribution, thereby effectively improving the support strength of the support feet 13. Furthermore, the structure of each support foot 13 is identical, such that the plurality of support feet 13 can be flexibly spliced and combined with each other.
As shown in FIG. 7 and FIG. 8, in some embodiments, the first end 1301 of the support foot 13 can be provided with a first clamping portion 132. The first clamping portion 132 can be convexly disposed from the sidewall of the clamping groove 1303 toward the interior of the clamping groove 1303. A first positioning groove 1304 can be concavely formed in the positioning portion 131. The first positioning groove 1304 can be formed corresponding to the first clamping portion 132.
When the positioning portion 131 is inserted into the clamping groove 1303 in place, the first clamping portion 132 is embedded into the first positioning groove 1304 to fix the positioning portion 131 within the clamping groove 1303 in a clamped manner.
Specifically, the first end 1301 of the support foot 13 not only is provided with the clamping groove 1303, but also has the first clamping portion 132 convexly disposed toward the interior of the clamping groove 1303 through the sidewall of the clamping groove 1303. Correspondingly, the positioning portion 131 on the second end 1302 of the support foot 13 not only is used for cooperating with the clamping groove 1303, but also has the first positioning groove 1304 concave in the surface, and the first positioning groove 1304 is formed corresponding to the first clamping portion 132. Thus, when the positioning portion 131 is inserted into the clamping groove 1303, the first clamping portion 132 can be accurately embedded into the first positioning groove 1304, such that the positioning portion 131 is securely clamped into the clamping groove 1303.
In the embodiments of the present disclosure, through further cooperative clamped-connection of the first clamping portion 132 with the first positioning groove 1304 between the positioning portion 131 and the clamping groove 1303, the splicing structure between the adjacent support feet 13 obtains further reinforcement, improving the stability of the splicing structure between the plurality of support feet 13, facilitating that the support feet 13 become less prone to loosening or detachment during prolonged usage. Regarding mounting efficiency, during insertion of the positioning portion 131 into the clamping groove 1303 by the user, as the positioning portion 131 moves within the clamping groove 1303 until the first clamping portion 132 is clamped into the first positioning groove 1304, the adjacent support feet 13 can be fixed, achieving rapid splicing between the support feet 13, significantly simplifying mounting steps, and improving mounting efficiency.
As shown in FIG. 7 and FIG. 8, in some embodiments, the shape and dimensions of the first clamping portion 132 can fit those of the first positioning groove 1304. For example, the first clamping portion 132 may be configured as a triangular structure; correspondingly, the first positioning groove 1304 may be configured as a concave triangular groove.
In some other embodiments, the first clamping portion 132 may also be convexly disposed on the positioning portion 131. The first positioning groove 1304 may also be concavely formed from the sidewall of the clamping groove 1303. The first positioning groove 1304 can be formed corresponding to the first clamping portion 132, and the first clamping portion 132 can be clamped into the groove.
As shown in FIG. 7 and FIG. 8, in some embodiments, the surface of the first clamping portion 132 can form a first guiding inclined surface (not shown in the figures). The first guiding inclined surface can tilt toward the first positioning groove 1304. The first guiding inclined surface can be used for guiding cooperative clamped-connection of the first clamping portion 132 with the first positioning groove 1304, or guiding detachment of the first clamping portion 132 from the first positioning groove 1304. Specifically, the first guiding inclined surface can reduce the frictional resistance during the clamped connection between the first clamping portion 132 and the first positioning groove 1304, thereby improving the smoothness of the support feet 13 during splicing, and further improving mounting efficiency.
As shown in FIG. 4, in some embodiments, the support foot 13 is detachably connected to the chassis 12. A detachable connection structure may be between the support foot 13 and the chassis 12. In this way, the user can selectively use the support feet 13 to support the chassis 12. For example, rollers 16 are disposed on the chassis 12, and the user moves the air conditioner to the usage position and can fix the position of the air conditioner by mounting the support feet 13. When the user needs to move the air conditioner, the support feet 13 can be detached from the chassis 12, thereby preventing the friction force formed between the support feet 13 and the ground and increasing the movement difficulty.
As shown in FIG. 4, in some embodiments, the support foot 13 and the chassis 12 may be connected through an insertion structure. The insertion structure between the support foot 13 and the chassis 12 can reduce the difficulty for the user to mount and detach the support foot 13, improving the usage convenience for the user.
As shown in FIG. 4, in some embodiments, a side of the chassis 12 facing the support foot 13 can be provided with an insertion portion. The insertion portion can be used for being connected to the support foot, such that the support foot 13 is connected to the peripheral side of the chassis 12. Next take the insertion portion as an insertion groove 1201 for example, to describe a connection structure between the insertion portion and the chassis 12 in detail.
As shown in FIG. 4 and FIG. 9, in some embodiments, a side of the support foot 13 facing the chassis 12 can be provided with an insertion column 133. The insertion column 133 can extend toward the chassis 12. A side of the chassis 12 facing the support foot 13 can be provided with an insertion groove 1201. The insertion groove 1201 can extend toward a side away from the support foot 13. The insertion column 133 can be disposed opposite to the insertion groove 1201.
The insertion column 133 extends along the support foot 13 toward the chassis 12, such that an accurate alignment fixed structure can be formed between the support foot 13 and the chassis 12. In this way, the support foot 13 can be directly inserted in an aligned manner and connected to the chassis 12, reducing the mounting difficulty between the support foot 13 and the chassis 12, and effectively improving mounting efficiency. Furthermore, the support foot 13 is directly inserted into the insertion groove 1201 of the chassis 12 through the insertion column 133, such that a connection fixed structure is provided between the support foot 13 and the chassis 12, further preventing the support foot 13 from shifting or detachment due to vibration or external force action. Meanwhile, the insertion structure makes force reception of the support feet 13 more uniform, improving the durability of the support feet 13.
As shown in FIG. 3 and FIG. 4, in some embodiments, a plurality of insertion grooves 1201 may be formed. The plurality of insertion grooves 1201 are formed corresponding to the insertion columns 133 of the plurality of support feet 13. The insertion column 133 of each support foot 13 is inserted into the corresponding insertion groove 1201 in an aligned manner.
Specifically, a plurality of insertion grooves 1201 can be formed corresponding to the support feet 13, and the plurality of support feet 13 can be inserted into the insertion grooves 1201 through the insertion columns 133, respectively, such that the plurality of support feet 13 are respectively connected to the chassis 12.
As shown in FIG. 4 and FIG. 5, in some embodiments, a side of the support foot 13 facing the chassis 12 may be provided with a plurality of insertion columns 133.
It should be noted that due to relying solely on a single insertion column 133 to connect the support foot 13 and the chassis 12, the connection is prone to loosening from external force or vibration. By arranging the plurality of insertion columns 133 on the support foot 13, correspondingly, a corresponding number of insertion grooves 1201 are formed in the chassis 12, such that the connection points between the support foot 13 and the chassis 12 can be increased. The plurality of insertion columns 133 of the same support foot 13 are inserted into the corresponding insertion grooves 1201 in the chassis 12, respectively, such that a more stable multi-point support structure is formed, effectively preventing each support foot 13 from loosening or shifting from the chassis 12.
As shown in FIG. 4 and FIG. 5, in some embodiments, a side of the support foot 13 facing the chassis 12 may be provided with two insertion columns 133.
As shown in FIG. 4, in some embodiments, the shape and depth of the insertion column 133 can fit those of the insertion groove 1201. For example, the insertion column 133 may be of a cuboid columnar structure; correspondingly, the insertion groove 1201 may be configured as a groove being of a cuboid columnar structure.
As shown in FIG. 9 and FIG. 10, in some embodiments, a second clamping portion 134 can be convexly disposed on the insertion column 133. A second positioning groove 1202 can be concavely formed in the insertion groove 1201. The second positioning groove 1202 can be formed corresponding to the second clamping portion 134. When the insertion column 133 is inserted into the insertion groove 1201 in place, the second clamping portion 134 can be embedded into the second positioning groove 1202 to fix the insertion column 133 within the insertion groove 1201 in a clamped manner.
Specifically, by convexly disposing the second clamping portion 134 on the insertion column 133, the second positioning groove 1202 is concavely formed in the insertion groove 1201, and the second clamping portion 134 can be clamped into the second positioning groove 1202, such that an additional connection point is provided for the insertion structure between the insertion column 133 and the chassis 12, improving the connection strength between the insertion column 133 and the insertion groove 1201 of the chassis 12, and preventing the insertion column 133 from loosening or detachment within the insertion groove 1201. Regarding mounting efficiency, during insertion of the insertion column 133 into the insertion groove 1201 by the user, as the insertion column 133 moves within the insertion groove 1201 until the second clamping portion 134 is clamped into the second positioning groove 1202, the support foot 13 can be fixed to the chassis 12, achieving rapid mounting between the support foot 13 and the chassis 12, significantly simplifying mounting steps, and improving mounting efficiency.
As shown in FIG. 4 and FIG. 10, in some embodiments, the shape and dimensions of the second clamping portion 134 can fit those of the second positioning groove 1202. For example, the second clamping portion 134 may be configured as a triangular structure; correspondingly, the second positioning groove 1202 may be configured as a triangular groove.
As shown in FIG. 10, in some embodiments, the surface of the second clamping portion 134 can form a second guiding inclined surface 1308. The second guiding inclined surface 1308 can tilt toward the second positioning groove 1202. The second guiding inclined surface 1308 can be used for guiding cooperative clamped-connection of the second clamping portion 134 with the second positioning groove 1202, or guiding detachment of the second clamping portion 134 from the second positioning groove 1202. Specifically, the second guiding inclined surface 1308 can reduce the frictional resistance during the clamped connection between the second clamping portion 134 and the second positioning groove 1202, thereby improving the smoothness during insertion where the support feet 13 are inserted and fixed to the chassis 12, and further improving mounting efficiency.
In some other embodiments, a second clamping portion 134 can also be convexly disposed in the insertion groove 1201. A second positioning groove 1202 can also be concavely formed in the insertion column 133. The second positioning groove 1202 can be formed corresponding to the second clamping portion 134, and the second clamping portion 134 can be clamped into the second positioning groove 1202.
As shown in FIG. 6 and FIG. 7, in some embodiments, the insertion column 133 can include a connection column 1331. The connection column 1331 can be connected to the support foot 13. The connection column 1331 can be convexly disposed from a side of the support foot 13 facing the chassis 12. The connection column 1331 serves as a main body portion of the insertion column 133. The shape and dimensions of the connection column 1331 can be identical to those of the insertion groove 1201, such that the connection column 1331 can be easily inserted into the insertion groove 1201, and sufficient supporting force is provided when insertion is in place.
As shown in FIG. 6, FIG. 7, and FIG. 10, in some embodiments, the insertion column 133 can include an extension arm 1332. The extension arm 1332 can be disposed on the connection column 1331. The extension arm 1332 can have a fixed end 13321 and a free end 13322. The fixed end 13321 can be connected to the insertion column 133. The free end 13322 can extend toward a direction close to the support foot 13. The free end 13322 can be provided with the second clamping portion 134.
The fixed end 13321 of the extension arm 1332 is connected to the connection column 1331, and the free end 13322 of the extension arm 1332 extends toward a direction close to the support foot 13. By disposing the free end 13322, the extension arm 1332 possesses a certain elasticity and restoring force, and the second clamping portion 134 is disposed at the free end 13322. When the user inserts the connection column 1331 into the insertion groove 1201, the extension arm 1332 gradually extends into the insertion groove 1201 as the connection column 1331 moves within the insertion groove 1201, the second clamping portion 134 is clamped into the second positioning groove 1202 and applies force to the extension arm 1332, and the free end 13322 of the extension arm 1332 deforms correspondingly under force, providing certain buffer and adaptive capabilities during insertion. Thus, the insertion column 133 can adapt to different insertion angles and depths during insertion into the insertion groove 1201, improving flexibility during insertion.
As shown in FIG. 6 and FIG. 10, in some embodiments, the connection column 1331 can be provided with a through hole 1305. The through hole 1305 can penetrate vertically through the connection column 1331. The extension arm 1332 can be disposed in the through hole 1305. The fixed end 13321 can be connected to a sidewall of the through hole 1305 close to the chassis 12. The free end 13322 can extend toward a direction away from the chassis 12.
Specifically, the fixed end 13321 of the extension arm 1332 can be disposed close to the chassis 12 and connected to a sidewall of the through hole 1305 close to the chassis 12, and the free end 13322 can extend toward a side of the support foot 13 and can be disposed corresponding to the through hole 1305. When the second clamping portion 134 on the extension arm 1332 is inserted into or detached from the second positioning slot 1202, the extension arm 1332 can perform elastic buffering movement within the through hole 1305 due to the reaction force from the chassis 12. In this way, by forming the through hole 1305, the extension arm 1332 can be bent toward a direction away from the chassis 12 when subjected to external force, thereby providing necessary buffering and restoring force for the extension arm 1332. The through hole 1305 can accommodate the extension arm 1332 and allow the extension arm 1332 to undergo elastic buffering movement during insertion into or detachment from the second positioning groove 1202, not only improving the insertion smoothness between the connection column and the chassis 12, but also improving the durability and stability of the insertion structure.
In some embodiments, the through hole 1305 may not penetrate through the upper and lower ends of the connection column 1331. The depth of the through hole 1305 can fit the dimensions and shape of the extension arm 1332, meeting that the extension arm 1332 undergoes elastic movement during insertion into or detachment from the second positioning groove 1202.
As shown in FIG. 7 and FIG. 10, in some embodiments, the fixed end 13321 of the extension arm 1332 can be disposed at the lower end of the through hole 1305. The second clamping portion 134 can be disposed at the bottom of the free end 13322, and the second positioning groove 1202 is concavely formed in the bottom wall of the insertion groove 1201.
As shown in FIG. 6, in some embodiments, the insertion column 133 can include a reinforcement portion 1333. The reinforcement portion 1333 can be connected between a sidewall of the through hole 1305 and the extension arm 1332. By additionally disposing the reinforcement portion 1333, the structural strength between the extension arm 1332 and the connection column 1331 can be improved, thereby improving the reliability of the insertion process between the insertion column 133 and the chassis 12.
As shown in FIG. 4 and FIG. 11, in some embodiments, an inclined surface 1306 can be formed on the outer side of the support foot 13 away from the chassis 12. The inclined surface 1306 can extend from the first end 1301 of the support foot 13 to the second end 1302 of the support foot 13. In a top-to-bottom direction, the inclined surface 1306 can tilt toward a direction away from the chassis 12. The outer surfaces of the plurality of support feet 13 can be sequentially spliced end to end to form an annular inclined structure 1300. The first end 1301 of the support foot 13 extends to the second end 1302 of the support foot 13. When the plurality of support feet 13 are spliced end to end to form an encircling structure on the outer side of the chassis 12, the first end 1301 and the second end 1302 of each inclined surface 1306 are correspondingly spliced to form an outside continuous surface that can cover the outer side of the chassis 12, thereby improving the appearance effect.
In some embodiments, as shown in FIG. 1, in a top-to-bottom direction, the inclined surface 1306 tilts toward a direction away from the chassis 12, that is, the lower end of the inclined surface 1306 tilts and extends toward the outer side of the air conditioner. When the plurality of support feet 13 are spliced end to end into one, the annular inclined structure 1300 can be formed. Compared with the current technical solution where a plurality of rod-shaped support feet 13 are individually arranged to be supported at the bottom of the chassis 12, the annular inclined structure 1300 not only better conforms to user aesthetics but also prevents the user from striking against the support feet 13 when passing by the outer side of the air conditioner, thereby improving the usage experience of the user.
It should be noted that the annular inclined structure 1300 may also be conical. That is, the outer surface of the annular inclined structure 1300 formed by splicing multiple inclined surfaces 1306 is a conical peripheral surface.
As shown in FIG. 6 and FIG. 7, in some embodiments, the support foot 13 can be provided with a handle portion 135. The handle portion 135 can be formed by the inclined surface 1306 being concave toward the inner side of the housing 1.
Because the outer side of the support foot 13 away from the chassis 12 is configured as an inclined surface 1306, the user may find it inconvenient to grip or difficult to find a grip point during mounting and disassembly, affecting the usage process of the support foot 13. In the embodiments of the present disclosure, by concavely forming the handle portion 135 directly on the inner side of the inclined surface 1306 of the support foot 13 facing the housing 1, the user conveniently grips the handle portion 135 directly during mounting and assembly, disassembly, or transportation, reducing incidents of hand slippage or difficulty in gripping, and facilitating the mounting and disassembly processes of the support feet 13. Moreover, the handle portion 135 is concavely formed from the inclined surface 1306 of the support foot 13, and the handle portion 135 may be of a groove structure. In this way, the addition of extra components of the support feet 13 is avoided, and the configuration of the handle portion 135 does not affect the overall appearance of the support feet 13, balancing aesthetics and functionality.
As shown in FIG. 7, in some embodiments, the edge of the handle portion 135 is configured with a smooth edge or a non-slip texture. This can improve the comfort when the user grips the handle portion 135.
As shown in FIG. 12, in some embodiments, the air conditioner can include rollers 16. The rollers 16 can be disposed at the bottom of the chassis 12. By disposing the rollers 16 at the bottom of the chassis 12, the user can effortlessly push the air conditioner, enabling the air conditioner to flexibly move. This design is suitable for scenarios requiring frequent location adjustments and simultaneously reduces physical effort.
As shown in FIG. 12, in some embodiments, a plurality of rollers 16 may be disposed.
As shown in FIG. 12, in some embodiments, the plurality of rollers 16 can be arranged respectively close to the edge of the chassis 12. In this way, the space of the bottom occupied by the rollers 16 can be reduced, such that the overall air conditioner is more compact.
As shown in FIG. 12, in some embodiments, the bottom of the chassis 12 can be provided with an accommodating portion. The accommodating portion is used for accommodating the rollers, such that the rollers can be movably mounted at the bottom of the chassis 12. Next take the insertion portion as an accommodating groove 1203 for example, to describe a mounting structure between the chassis 12 and the rollers in detail.
As shown in FIG. 9 and FIG. 12, in some embodiments, the bottom of the chassis 12 can be provided with an accommodating groove 1203. A side of the support foot 13 facing the chassis 12 can be provided with a clearance groove 1307. The support foot 13 can be disposed on the outer side of the roller 16. When the support feet 13 are arranged around the outer side of the chassis 12, a portion of each roller 16 can be located within the accommodating groove 1203, while another portion of each roller 16 can be located within the clearance groove 1307.
By forming the accommodating groove 1203 at the bottom of the chassis 12, a portion of each roller 16 is embedded within the accommodating groove 1203 of the chassis 12, such that a portion of the roller 16 is embedded into the structure of the chassis 12, thereby reducing the overall height, preventing the machine body from being elevated by the rollers 16, reducing shaking of the air conditioner even during pushing or pulling, and improving the usage experience. Moreover, the accommodating groove 1203 partially encloses the roller 16, providing a certain dust protection effect, reducing the foreign matter entering the roller 16, and improving the durability of the roller 16.
In addition, because the support feet 13 and the rollers 16 are typically arranged independently, structural interference between them can occur, preventing the rollers 16 from achieving full ground contact, thereby affecting the movement effect. By forming the clearance groove 1307 on the side of the support foot 13 facing the chassis 12, the other portion of the roller 16 is embedded within the clearance groove 1307. By reasonably utilizing the spatial arrangement of the support feet 13 and the rollers 16, the interference between the rollers 16 and the support feet 13 is prevented, such that the rollers 16 can roll smoothly.
As shown in FIG. 11, in some embodiments, the outer surface of the support foot 13 can be provided with a first mark 136. The first mark 136 can be disposed close to the first end 1301 of the support foot 13. The outer surface of the support foot 13 can be provided with a second mark 137. The second mark 137 can be disposed close to the second end 1302 of the support foot 13. The first mark 136 and the second mark 137 can be arranged opposite to each other at the junction of any two adjacent support feet 13. By arranging the first mark 136 and the second mark 137 on the outer surface of the support foot 13, the arrangement of the marks enables the user to quickly identify the correct splicing direction during mounting, thereby improving mounting efficiency. Moreover, by arranging the first mark 136 and the second mark 137 opposite to each other at the junction of adjacent support feet 13, it is beneficial for the user to visually judge whether splicing is correct, preventing mounting issues caused by directional errors, thereby reducing the mounting difficulty for the user during routine use.
The air conditioner according to the embodiments of the present disclosure can further be used for solving the problem of water storage space of the chassis so as to increase the water storage space of the chassis of the air conditioner. In related air conditioners, the chassis further undertakes the function of collecting and draining condensate water or rainwater to ensure normal device operation. The chassis design in related air conditioners exhibits certain defects, particularly regarding the water storage space. Due to the structural constraints in the chassis, the water storage space of the chassis is typically smaller in volume or lacks a dedicated water storage region, resulting in drainage blockages or overflow during rainy weather.
To solve the above problem, as shown in FIG. 13 and FIG. 14, an air conditioner provided by some embodiments of the present disclosure can include a housing 1. The housing 1 can be configured as a shell outside the air conditioner.
As shown in FIG. 13 and FIG. 14, in some embodiments, the housing 1 can include a main shell 11. The main shell 11 can extend along the height direction. The height dimension of the main shell 11 can be greater than the lateral width dimension and longitudinal width dimension of the main shell 11 so as to increase the height of the housing 1 and reduce the space occupied by the housing 1.
As shown in FIG. 15 and FIG. 16, in some embodiments, the housing 1 can include a chassis 12. The chassis 12 can be disposed at the bottom of the main shell 11. An accommodating space 10 can be formed between a space above the top of the chassis 12 and the interior of the main shell 11. The accommodating space 10 serves as a mounting space for other components of the air conditioner.
As shown in FIG. 15 and FIG. 16, in some embodiments, support feet 13 can be disposed on the peripheral side of the chassis 12. The support feet 13 can extend toward the peripheral direction of the chassis 12. The support feet 13 can be used for increasing the contact area between the bottom of the housing 1 and the ground, thereby improving the reliability of supporting the air conditioner by the chassis 12, and improving the stability of the air conditioner.
As shown in FIG. 15 and FIG. 16, in some embodiments, a plurality of support feet 13 may be disposed. The plurality of support feet 13 can be sequentially spliced end to end, such that the plurality of support feet 13 are arranged circumferentially around the peripheral side of the chassis 12. Thus, the plurality of support feet 13 can be arranged in an annular structure on the peripheral side of the chassis 12, improving the structural strength between the plurality of support feet 13 to form a complete annular structure. Meanwhile, the support feet 13 are prevented from causing collisions with the user, thereby improving the usage safety of the air conditioner.
As shown in FIG. 15 and FIG. 16, in some embodiments, the air conditioner can include a refrigerant circuit. The refrigerant circuit can be disposed in the housing 1. The refrigerant circuit can be disposed in the accommodating space 10. The refrigerant circuit can include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end to end. A refrigerant flows circularly in the refrigerant circuit formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant cycle, the outdoor heat exchanger 22 and the indoor heat exchanger 23 may serve as a condenser and an evaporator, respectively, so that the refrigerant is evaporated in the evaporator to absorb heat and is condensed in the condenser to release heat, thereby enabling a refrigerating cycle or a heating cycle of the air conditioner to be executed.
As shown in FIG. 14, FIG. 15, and FIG. 16, in some embodiments, the air conditioner can include an outdoor fan assembly 3. The outdoor fan assembly 3 can be disposed opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used for introducing outdoor air into the housing 1 to exchange heat with the outdoor heat exchanger 22 to form a heat exchange air flow.
As shown in FIG. 13, FIG. 14, and FIG. 15, in some embodiments, the air conditioner can include an indoor fan assembly 4. The indoor fan assembly 4 can be disposed opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used for introducing indoor air into the housing 1 to exchange heat with the indoor heat exchanger 23 to form a heat exchange air flow.
As shown in FIG. 15 and FIG. 16, in some embodiments, the accommodating space 10 inside the housing 1 can include three layers of sub-spaces. The three layers of sub-spaces are respectively a first sub-space 110, a second sub-space 120, and a third sub-space 130 arranged in sequence from bottom to top. The compressor 21 can be disposed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 can be disposed in the second sub-space 120. The indoor heat exchanger 23 and the indoor fan assembly 4 can be disposed in the third sub-space 130. Thus, through the three layers of sub-spaces in sequence from bottom to top, the components such as the compressor 21, the outdoor heat exchanger 22, the outdoor fan assembly 3, the indoor heat exchanger 23, and the indoor fan assembly 4 can be arranged in a scattered manner at different height positions inside the housing 1, which is beneficial to improving the overall height of the air conditioner, reducing the width and thickness dimensions of the air conditioner, and reducing the space of the usage site occupied by the air conditioner.

The indoor air outlet 112 can be in communication with the exterior of the housing 1. The indoor air outlet 112 can be in communication with an indoor space. The indoor air outlet 112 can be formed in the corresponding outer wall of the third sub-space 130 and can be disposed opposite to an air outlet end of the indoor fan assembly 4. Thus, during operation, the indoor fan assembly 4 can draw indoor air through the indoor air inlet 111 to exchange heat with the indoor heat exchanger 23. The heat-exchanged air can be discharged back into the indoor space outside the housing 1 through the air outlet end of the indoor fan assembly and the indoor air outlet 112.
As shown in FIG. 13 and FIG. 15, in some embodiments, an outer wall of the housing 1 can be provided with an air deflector 113. The air deflector 113 is rotatably disposed at the indoor air outlet 112. A plurality of air deflectors 113 may be disposed. The plurality of air deflectors 113 can be arranged side by side at the indoor air outlet 112. During rotation, the air deflectors 113 can open or close the indoor air outlet 112. When the air deflectors 113 rotate to open the indoor air outlet 112, the air deflectors 113 can further change the air outlet direction of the indoor air outlet 112.
As shown in FIG. 14 and FIG. 16, in some embodiments, the air conditioner can include an air inlet pipe 14. The air inlet pipe 14 can be disposed inside a space outside the housing 1. One end of the air inlet pipe 14 can be in communication with the air inlet end of the outdoor fan assembly 3. The other end of the air inlet pipe 14 can be in communication with the outdoor space. The air outlet end of the outdoor fan assembly 3 can be disposed toward the outdoor heat exchanger 22. Thus, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet pipe 14, introduce the outdoor air into the housing 1, and blow it toward the outdoor heat exchanger 22 to heat or cool the outdoor heat exchanger 22. As shown in FIG. 14 and FIG. 16, in some embodiments, the air conditioner can include an air outlet pipe 15. The air outlet pipe 15 can be disposed inside a space outside the housing 1. One end of the air outlet pipe 15 can be in communication with the inner space of the housing 1. The other end of the air outlet pipe 15 can be in communication with the outdoor space. Thus, during operation, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet pipe 14, introduce the outdoor air into the housing 1, and blow it toward the outdoor heat exchanger 22. The air flowing through the outdoor heat exchanger 22 inside the housing 1 is discharged to the outdoor space through the air outlet pipe 15, achieving the outdoor air cycle.
It should be noted that in some other embodiments, the air inlet pipe 14 can also be used for air discharge, and the air outlet pipe 15 can also be used for air entering. The air outlet pipe 15 can introduce outdoor air into the housing 1 to exchange heat with the outdoor heat exchanger 22. The heat-exchanged air can be conveyed to the outdoors through the air inlet pipe 14 under the action of the outdoor fan assembly 3.
As shown in FIG. 14 and FIG. 16, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 can be disposed on the outer side of the third sub-space 130. A receiving region 140 can be concavely disposed on the outer wall of the upper portion of the housing 1 corresponding to the third sub-space 130. The air inlet pipe 14 and the air outlet pipe 15 can be disposed within the receiving region 140, such that the air inlet pipe 14 and the air outlet pipe 15 can be disposed above the second sub-space 120, enabling the air inlet pipe 14 and the air outlet pipe 15 to be disposed above the outdoor heat exchanger 22 and the outdoor fan assembly 3.
As shown in FIG. 14 and FIG. 16, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 can be arranged side by side within the receiving region 140 on the outer wall of the housing 1. The lower end of the air inlet pipe 14 can be in communication with the air inlet end of the outdoor fan assembly 3. The lower end of the air outlet pipe 15 can be in communication with the second sub-space 120 inside the housing 1. The upper end of the air inlet pipe 14 and the upper end of the air outlet pipe 15 can be connected to the outdoor space. During mounting of the air conditioner, the air inlet pipe 14 and the air outlet pipe 15 can be lengthened and mounted and fixed to a wall or window, thereby establishing communication with the outdoor space.
As shown in FIG. 15 and FIG. 16, in some embodiments, the air conditioner can include a first water collection tray 5. The first water collection tray 5 can be disposed in the accommodating space 10 inside the housing 1. The first water collection tray 5 can be disposed in a region between the first sub-space 110 and the second sub-space 120. The outdoor heat exchanger 22 can be disposed above the first water collection tray 5. The first water collection tray 5 can be used for receiving condensate water flowing down from the outer wall of the outdoor heat exchanger 22. During heating operation of the air conditioner, the refrigerant can be evaporated to absorb heat in the outdoor heat exchanger 22, such that the surface temperature of the outdoor heat exchanger 22 is decreased. Water vapor in the air condenses into water, falling into the first water collection tray 5 at the bottom of the outdoor heat exchanger 22 to be collected within the first water collection tray 5 or discharged through a drainage outlet on the first water collection tray 5, thereby preventing risks of air conditioner slip and human slip due to condensate water dripping to the ground.
As shown in FIG. 15 and FIG. 16, in some embodiments, a bottom end opening of the air outlet pipe 15 can be disposed in a space above the first water collection tray 5. After outdoor rainwater enters the housing 1 through the air outlet pipe 15, the outdoor rainwater can be received by the first water collection tray 5, preventing the rainwater from direct flow toward other regions inside the housing 1 or leakage from the exterior of the housing 1 to flow toward the ground.
As shown in FIG. 16, in some embodiments, a sidewall of the first water collection tray 5 can be provided with a first drainage outlet 51. A drain valve 52 can be disposed at the first drainage outlet 51. The drain valve 52 can block the first drainage outlet 51. When the drain valve 52 opens the first drainage outlet 51, the first drainage outlet 51 can be in communication with the exterior of the first water collection tray 5, and water within the first water collection tray 5 can flow out of the first water collection tray 5 through the first drainage outlet 51.
As shown in FIG. 14 and FIG. 16, in some embodiments, the drain valve 52 can be disposed outside the housing 1, and the first drainage outlet 51 can be in communication with the exterior of the housing 1. When the drain valve 52 opens the first drainage outlet 51, water within the first water collection tray 5 can flow out of the housing 1 through the first drainage outlet 51.
As shown in FIG. 15 and FIG. 16, in some embodiments, the air conditioner can include a second water collection tray 6. The second water collection tray 6 can be disposed in the accommodating space 10 inside the housing 1. The second water collection tray 6 can be disposed in a region between the second sub-space 120 and the third sub-space 130. The indoor heat exchanger 23 can be disposed above the second water collection tray 6. The indoor heat exchanger 4 can be disposed above the second water collection tray 6. The second water collection tray 6 can be used for receiving condensate water flowing down from the outer wall of the indoor heat exchanger 23. During refrigerating operation of the air conditioner, the refrigerant can be evaporated to absorb heat in the indoor heat exchanger 23, such that the surface temperature of the indoor heat exchanger 23 is decreased. Water vapor in the air condenses into water, falling into the second water collection tray 6 at the bottom of the indoor heat exchanger 23 to be collected within the second water collection tray 6 or discharged through a drainage outlet on the second water collection tray 6, thereby preventing risks of air conditioner slip and human slip due to condensate water dripping to the ground.
As shown in FIG. 15 and FIG. 16, in some embodiments, a bottom surface of the second water collection tray 6 can be provided with a second drainage outlet (not shown in the figures). The second drainage outlet is disposed above the outdoor heat exchanger 22 and the first water collection tray 5. Condensate water within the second water collection tray 6 can flow to the outdoor heat exchanger 22 through the second drainage outlet to cool the outdoor heat exchanger 22, and then flow down into the first water collection tray 5 along the outer wall of the outdoor heat exchanger 22. Thus, condensate water within the second water collection tray 6 can be drained into the first water collection tray 5 to be collected to exchange heat with the outdoor heat exchanger 22 to cool the outdoor heat exchanger 22. For example, during refrigerating operation of the air conditioner, the outdoor heat exchanger 22 serves as a condenser requiring heat dissipation to the outside, and the indoor heat exchanger 23 serves as an evaporator requiring heat absorption from the outside. Air condenses into condensate water on the surface of the indoor heat exchanger 23, and the condensate water can flow into the second water collection tray 6 along the surface of the indoor heat exchanger 23, flow onto the outer wall of the outdoor heat exchanger 22 through the second drainage outlet of the second water collection tray 6 to dissipate hear from and cool the outdoor heat exchanger 22, and finally flow down into the first water collection tray 5 along the outer wall of the outdoor heat exchanger 22 to be collected.
As shown in FIG. 15 and FIG. 16, in some embodiments, the air conditioner can include a housing 1. The housing 1 can include a main shell 11 and a chassis 12. The main shell 11 and the chassis 12 form an inner accommodating space 10. The air conditioner can include a refrigerant circuit disposed in the accommodating space and including a compressor 21, a condenser, and an evaporator connected end to end. One of the condenser and the evaporator serves as the outdoor heat exchanger 22 and the other one serves as the indoor heat exchanger 23. The air conditioner can include an outdoor fan assembly 3, and the outdoor fan assembly 3 is disposed on one side of the outdoor heat exchanger 22 to drive outdoor air to flow through the outdoor heat exchanger 22 to exchange heat. The air conditioner can include an indoor fan assembly 4, and the indoor fan assembly 4 is disposed on one side of the indoor heat exchanger 23 to drive indoor air to flow through the indoor heat exchanger 23 to exchange heat. The air conditioner can include a first water collection tray 5, and the outdoor heat exchanger 22 is disposed above the first water collection tray 5. The air conditioner can include a second water collection tray 6, and the indoor heat exchanger 23 is disposed above the second water collection tray 6. The second water collection tray 6 is disposed above the outdoor heat exchanger 22. The air conditioner can include an air inlet pipe 14, and the air inlet pipe 14 is used for delivering the outdoor air to the outdoor heat exchanger 22 to exchange heat. The air conditioner can include an air outlet pipe 15, and the air outlet pipe 15 is used for delivering the heat exchange air to the outdoors under the action of the outdoor fan assembly 3. The air inlet pipe and the air outlet pipe are disposed above the outdoor heat exchanger and horizontally spaced apart from the indoor fan assembly. The compressor is disposed at the bottom of the shell, and the first water collection tray is disposed above the compressor.
As shown in FIG. 16 and FIG. 17, in some embodiments, the air conditioner can include a first air duct member 35. The first air duct member 35 can be disposed in the main shell 11. The first air duct member 35 can be disposed in the accommodating space 10. The first air duct member 35 can be used for supporting the internal structure of the air conditioner.

Thus, the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 in the second sub-space 120 can be improved.
It should be noted that in some other embodiments, the first air duct member 35 can also be used for supporting any one or more of the outdoor heat exchanger 22, the outdoor fan assembly 3, the first water collection tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, and the second water collection tray 6. For example, the first air duct member 35 can also be used for individually supporting the outdoor heat exchanger 22 and/or the indoor heat exchanger 23.
As shown in FIG. 16 and FIG. 17, in some embodiments, the outdoor fan assembly 3 can include a second air duct member 31.

The outdoor fan motor 32 can be fixed at the outer side of the second air duct member 31, such that an output shaft of the outdoor fan motor 32 extends into the volute structure to be in transmission connection with the outdoor fan. Thus, the outdoor fan motor 32 can drive the outdoor fan to rotate within the volute structure, thereby drawing the air from the outdoor space into the volute structure through the air inlet pipe 14 and blowing it into the second sub-space 120 for heat exchange contact with the outdoor heat exchanger 22. The heat-exchanged air can flow to the outdoors through the air outlet pipe 15. In this solution, a portion of the volute structure of the outdoor fan assembly 3 is integrated on the first air duct member 35, significantly improving the structural strength and stability of the outdoor fan assembly 3, thereby ensuring the reliable operation of the outdoor fan assembly 3.

The cooperation of the first water collection tank 124 and the second water collection tank 125 can effectively increase the water storage space of the chassis 12. Given the requirement for the first air duct member 35 to be supported on the chassis 12, the structural arrangement of the first water collection tank 124 and the second water collection tank 125 can effectively improve the space utilization efficiency of the chassis 12, thereby reasonably expanding the water storage space of the chassis 12.
As shown in FIG. 18, FIG. 20, and FIG. 22, in some embodiments, the first groove portion 12131 can be disposed between the first water collection tank 124 and the second water collection tank 125 in a transversely extending manner.

One end of the connection channel 122 can be in communication with the first water collection tank 124. The other end of the connection channel 122 can be in communication with the second water collection tank 125. The connection channel 122 can make the first water collection tank 124 in communication with the second water collection tank 125, such that rainwater or condensate water within the first water collection tank 124 can enter the second water collection tank 125 through the connection channel 122, and rainwater or condensate water within the second water collection tank 125 can also enter the first water collection tank 124 through the connection channel 122, fully utilizing the water storage space of the first water collection tank 124 and the second water collection tank 125, and improving the rainwater or condensate water storage effect, thereby effectively increasing and efficiently utilizing the water storage space of the chassis 12.
As shown in FIG. 18, FIG. 23, and FIG. 24, in some embodiments, the first water collection tank 124 can be disposed on one side of the first support rib 1211 away from the second support rib 1212.

The second overflow opening 1253 can be respectively in communication with the second water collection units 1251 on the two sides of the second partition plate 1252. Thus, the adjacent second water collection units 1251 can be in communication with each other through the second overflow opening 1253. When the water level of rainwater or condensate water within one of the second water collection units 1251 is higher than the first overflow opening 1243, it can flow into the adjacent second water collection unit 1251 through the second overflow opening 1253, thereby fully utilizing the water storage space of each second water collection unit 1251.

The top surface of the stepped portion 126 can be provided with a discharge opening 1261. The discharge opening 1261 can be in communication with a space below the bottom of the chassis 12. Thus, when the water level within the second water collection tank 125 is higher than the top end of the discharge opening 1261, excess condensate water or rainwater within the second water collection tank 125 can be discharged to outside the housing 1 through the discharge opening 1261; excess condensate water or rainwater within the first water collection tank 124 can first enter the second water collection tank 125 before being discharged outside the housing 1 through the discharge opening 1261. When a large amount of rainwater or condensate water exists, and the first water collection tank 124 and the second water collection tank 125 can no longer accommodate more water, excessive water on the chassis 12 can be discharged through the discharge opening 1261, preventing excessive accumulation of rainwater or condensate water inside the housing 1.
In some other embodiments, the stepped portion 126 and the discharge opening 1261 can also be disposed in the first water collection tank 124.

The rainwater entering the volute structure can be discharged in time through the drain hole 33, thereby flowing down onto the chassis 12 through the outer wall of the first air duct member 35 to be collected on the chassis 12. Through the drainage structure design and rational structural arrangement within the volute structure, rainwater accumulation inside the volute structure can be effectively prevented, ensuring stable operation of the outdoor fan assembly 3.
In some other embodiments, during heating operation of the air conditioner, condensate water generated within the outdoor fan assembly 3 can also be discharged in time through the drain hole 33, thereby flowing down onto the chassis 12 through the outer wall of the first air duct member 35 to be collected on the chassis 12, effectively preventing accumulation of condensate water inside the volute structure, and ensuring stable operation of the outdoor fan assembly 3.
The air conditioner according to embodiments of the present disclosure can further be used for solving the problem of heat dissipation of a reactor to improve the heat dissipation effect and efficiency of a reactor in the air conditioner. In related air conditioners, reactors are typically provided to serve functions including filtering, stabilizing current and voltage, improving power factor, and suppressing inrush currents. The reactor in related air conditioners is typically disposed on the chassis through a protective cover for protection and heat dissipation. However, the heat dissipation efficiency of the reactor relies on airflow flowing within the internal space of the air conditioner. Due to the irrational internal component layout within the air conditioner, the reactor is prone to poor heat dissipation.
To solve the above problem, as shown in FIG. 13 and FIG. 14, an air conditioner provided by some embodiments of the present disclosure can include a housing 1. The housing 1 can be configured as a shell outside the air conditioner.

A refrigerant flows circularly in the refrigerant circuit formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant cycle, the outdoor heat exchanger 22 and the indoor heat exchanger 23 may serve as a condenser and an evaporator, respectively, so that the refrigerant is evaporated in the evaporator to absorb heat and is condensed in the condenser to release heat, thereby enabling a refrigerating cycle or a heating cycle of the air conditioner to be executed.
As shown in FIG. 16 and FIG. 25, in some embodiments, the air conditioner can include a first air duct member 35. The first air duct member 35 can be disposed in the main shell 11. The first air duct member 35 can be disposed in the accommodating space 10. The first air duct member 35 can be used for supporting the internal structure of the air conditioner. For example, the first air duct member 35 can be used for supporting the outdoor heat exchanger 22, the outdoor fan assembly 3, the first water collection tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the second water collection tray 6, etc., thereby enhancing the structural strength and stability inside the air conditioner.

As shown in FIG. 28 and FIG. 29, in some embodiments, a collection groove 127 concave downward is formed in the bottom surface of the water collection tank 100. The heat sink 93 can be disposed vertically opposite to the collection groove 127. The lower end of the heat sink 93 can extend into the collection groove 127. Thus, the collection groove 127 can be lower than the bottom surface of the water collection tank 100, such that water within the water collection tank 100 can be preferentially stored within the collection groove 127, elevating the water level within the collection groove 127, thereby increasing the contact area between the lower end of the heat sink 93 and the water, improving the heat dissipation efficiency of the heat sink 93, and thus improving the heat dissipation performance of the reactor 91.

As shown in FIG. 26, FIG. 32, and FIG. 33, in some embodiments, the mounting base 92 can include a mounting base plate 922. The mounting base plate 922 can extend from one side of the lower end of the mounting side plate 921 toward the bottom of the reactor 91. The mounting base plate 922 can be erected above the chassis 12. The reactor 91 can be fixed above the mounting base plate 922. The mounting base plate 922 can be supported at the bottom of the reactor 91, such that the reactor 91 can be stably fixed on the mounting base 92.
It should be noted that in some other embodiments, the heat sink 93 may also extend downward from the mounting base plate 922. At this time, the bottom of the reactor 91 can be attached to the top surface of the mounting base plate 922. Thus, the heat from the reactor 91 can be transferred to the heat sink 93 through the mounting base plate 922, such that through the cooperation between the mounting base plate 922 and the heat sink 93, the heat dissipation efficiency of the reactor 91 is improved, thereby improving the overall heat dissipation performance of the reactor 91.
As shown in FIG. 29, FIG. 32, and FIG. 33, in some embodiments, a first heat dissipation opening 9221 is formed in the mounting base plate 922. Air below the bottom of the mounting base 92 can enter the space above the mounting base plate 922 through the first heat dissipation opening 9221 and flow through the reactor 91, such that the heat from the reactor 91 is dissipated by utilizing air flow.

The first heat dissipation opening 9221 can be in communication with the discharge opening 1261. Thus, air outside the housing 1 can enter the water collection tank 100 through the discharge opening 1261 on the chassis 12, and then enter the mounting base 92 through the first heat dissipation opening 9221 on the mounting base plate 922 to be in contact with the reactor 91, achieving heat dissipation of the reactor 91. Thus, fresh air outside the housing 1 can be utilized to dissipate heat from the reactor 91 inside the housing 1.
As shown in FIG. 26, FIG. 30, and FIG. 32, in some embodiments, the reactor assembly 9 can include a protective cover 94. The protective cover 94 can cover the mounting base 92. The protective cover 94 and the mounting base 92 can be spliced into a reactor box 90. The reactor 91 can be located in the reactor box 90. Thus, by splicing the protective cover 94 and the mounting base 92 into the reactor box 90, the reactor 91 can be protected in the reactor box 90.
As shown in FIG. 17, FIG. 26, FIG. 30, and FIG. 32, in some embodiments, the mounting side plate 921 can be provided with a vent 9213 in communication with the interior of the reactor box 90, and the protective cover 94 is provided with a second heat dissipation opening 941 in communication with the interior of the reactor box 90. An air vent 3521 can be formed in the sidewall of the first air duct member 35. The air vent 3521 can be formed opposite to and in communication with the vent 9213. Air outside the protective cover 94 can enter the reactor box 90 through the second heat dissipation opening 941 to dissipate heat from the reactor 91, and then be discharged through the vent 9213 and the air vent 3521. Thus, a stable airflow heat dissipation channel can be formed inside the reactor box 90.
As shown in FIG. 17, FIG. 26, FIG. 32, and FIG. 33, in some embodiments, air outside the reactor box 90 can also enter the reactor box 90 through the first heat dissipation opening 9221 on the mounting base plate 922 to dissipate heat from the reactor 91, and then be discharged through the vent 9213 and the air vent 3521.
It should be noted that in some other embodiments, air outside the reactor box 90 can also enter the reactor box 90 through the air vent 3521 and the vent 9213 to dissipate heat from the reactor 91, and then be discharged through the first heat dissipation opening 9221 or the second heat dissipation opening 941.
As shown in FIG. 17, FIG. 26, and FIG. 31, in some embodiments, a ventilating grille 942 can be disposed on the sidewall of the protective cover 94. The ventilating grille 942 can be in communication with the interior of the reactor box 90. Air outside the reactor box 90 can also enter the reactor box 90 through the ventilating grille 942 to dissipate heat from the reactor 91, and then be discharged through the vent 9213 and the air vent 3521.
As shown in FIG. 31 and FIG. 33, in some embodiments, a hook portion 943 can be disposed on one side of the protective cover 94 close to the vent 9213. The hook portion 943 can extend into the vent 9213 and be in clamped connection with the side edge of the vent 9213.
The air conditioner according to embodiments of the present disclosure can further be used for solving the problem of heat dissipation of electronic control components such as an electric control box to improve the heat dissipation effect on electronic control components. In related air conditioners, the electrical control component includes an electric control box and an electric control board. The electric control board is disposed within the electric control box, and the electric control box is provided with a heat dissipation inlet and a heat dissipation outlet. Air can flow into the electric control box through the heat dissipation inlet, and the air flows out of the heat dissipation outlet after flowing through the electric control board, to carry away heat from the electric control board, thereby achieving heat dissipation and cooling of the electric control board. However, due to the irrational structural arrangement in related technologies, the effect of generating flowing airflow in the electric control box is poor, the airflow flowing rate in the electric control box is relatively slow or the airflow rate is smaller, failing to effectively carry away heat from the electric control board, resulting in poor heat dissipation and cooling effects.
To solve the above problem, as shown in FIG. 34 and FIG. 35, an air conditioner according to some embodiments of the present disclosure can include a housing 1. The housing 1 is provided with an indoor air inlet 111 and an indoor air outlet 112. Indoor air can enter the housing 1 through the indoor air inlet 111 and flow back to the indoors through the indoor air outlet 112.
As shown in FIG. 36, in some embodiments, the housing 1 can also be provided with an outdoor air inlet 114 and an outdoor air outlet 115. Indoor air can enter the housing 1 through the outdoor air inlet 114 and flow back to the outdoors through the outdoor air outlet 115.
As shown in FIG. 36, in some embodiments, the air conditioner can include an indoor heat exchanger 23. The indoor heat exchanger 23 is disposed in the housing 1. Indoor air after entering the housing 1 through the indoor air inlet 111 can exchange heat with the indoor heat exchanger 23.
As shown in FIG. 36, in some embodiments, the air conditioner can include an indoor fan assembly. The indoor fan assembly is disposed in the housing 1. The indoor fan assembly drives indoor air to enter the housing 1 from the indoor air inlet 111, and the indoor air after exchanging heat with the indoor heat exchanger 23 flows back to the indoors through the indoor air outlet 112. The indoor fan assembly can guide the flow of indoor air, to accelerate the flow rate of indoor air to flow into the housing 1 from the indoor air inlet 111 and flow back to the indoors from the indoor air outlet 112, thereby improving the heat exchange efficiency between the indoor air and the indoor heat exchanger 23.
As shown in FIG. 36 and FIG. 37, in some embodiments, the air conditioner can include an outdoor heat exchanger 22. The outdoor heat exchanger 22 is disposed in the housing 1. Outdoor air can enter the housing 1 through the outdoor air inlet 114 and exchange heat with a refrigerant in the outdoor heat exchanger 22. For example, during indoor refrigerating operation of the air conditioner, a high-temperature refrigerant flowing out of the compressor can first flow to the outdoor heat exchanger 22 and release heat to the outdoor air through the outdoor heat exchanger 22. After the temperature of the refrigerant is decreased, the refrigerant flows to the indoor heat exchanger 23, to absorb heat from the indoor air through the indoor heat exchanger 23, such that the temperature of the indoor air is decreased, thereby achieving indoor refrigerating. During indoor heating operation of the air conditioner, a high-temperature refrigerant flowing out of the compressor can first flow to the indoor heat exchanger 23 and release heat to the indoor air through the indoor heat exchanger 23, such that the indoor temperature is increased, thereby achieving indoor heating. Then, after the temperature of the refrigerant is decreased, the refrigerant flows to the outdoor heat exchanger 22 and absorbs heat from the outdoor air through the outdoor heat exchanger 22; after the temperature of the refrigerant is increased, the refrigerant flows back to the compressor, thereby completing the heating cycle.
As shown in FIG. 37, in some embodiments, the air conditioner can include an air duct assembly 300. The air duct assembly 300 is disposed in the housing 1, and the air duct assembly 300 is respectively in communication with the outdoor air inlet 114 and the outdoor air outlet 115. The air duct assembly 300 can guide outdoor air, such that the outdoor air flowing into the housing 1 flows more orderly in the housing 1.
As shown in FIG. 37, in some embodiments, the air conditioner can include an outdoor fan 34. The outdoor fan 34 is disposed in the air duct assembly 300. The outdoor fan 34 drives outdoor air to enter the housing 1 from the outdoor air inlet 114, and the outdoor air after exchanging heat with the outdoor heat exchanger 22 flows back to the outdoors through the outdoor air outlet 115. That is, the outdoor fan 34 can guide the flow of outdoor air, to accelerate the flow rate of outdoor air to flow into the housing 1 from the outdoor air inlet 114 and flow back to the outdoors from the outdoor air outlet 115, thereby improving the heat exchange efficiency between the outdoor air and the outdoor heat exchanger 22. The outdoor fan 34 may be a centrifugal fan.
As shown in FIG. 36 and FIG. 37, in some embodiments, the air conditioner can include an electric control component 800. The electric control component 800 can be disposed inside the housing 1 and located on the lower side of the outdoor fan 34. The electric control component 800 can be electrically connected to the compressor, the indoor fan assembly, and the outdoor fan 34.
As shown in FIG. 40 and FIG. 41, in some embodiments, the electric control component 800 can include an electric control box 8. The electric control box 8 is provided with a heat dissipation inlet 813 and a heat dissipation outlet 812. In this way, air can flow into the electric control box 8 through the heat dissipation inlet 813 and flow out of the electric control box 8 through the heat dissipation outlet 812. The airflow flowing through the interior of the electric control box 8 can carry away heat within the electric control box 8, thereby reducing the internal temperature of the electric control box 8 and preventing the electric control component 800 from reaching excessive temperatures.
As shown in FIG. 40 and FIG. 41, in some embodiments, the electric control component 800 can further include an electric control board 820. The electric control board 820 is disposed in the electric control box 8. The electric control box 8 can provide a mounting position for the electric control board 820, and serves a function of protecting the electric control board 820. When the airflow flows through the interior of the electric control box 8, the airflow can carry away heat from the electric control board 820, thereby preventing the electric control board 820 from reaching excessive temperatures, and enabling stable operation of the electric control board 820.
As shown in FIG. 37 and FIG. 38, in some embodiments, the outdoor heat exchanger 22 can be disposed on one side of the air duct assembly 300, and a negative-pressure space 340 is formed between the outdoor heat exchanger 22 and the air duct assembly 300. The heat dissipation outlet 812 can be in communication with the negative-pressure space 340. Specifically, during operation of the air conditioner, the outdoor fan 34 rotates, such that a negative pressure can be generated within the negative-pressure space 340, that is, suction is generated within the negative-pressure space 340. The suction can suck airflow from the outdoor heat exchanger 22 and the electric control box 8 into the air duct assembly 300 and discharge the airflow to the outdoors. That is, the negative pressure within the negative-pressure space 340 can be utilized to generate forced convection within the electric control box 8, such that more air can flow into the electric control box 8 from the heat dissipation inlet 813, and then flow to the negative-pressure space 340 from the heat dissipation outlet 812. The volume of airflow flowing through the interior of the electric control box 8 can be larger, such that the heat from the electric control board 820 can be carried away by utilizing the flowing airflow, preventing the electric control component 800 from reaching excessive temperatures, and achieving a better heat dissipation effect on the electric control component 800.
Moreover, the heat dissipation outlet 812 can be in direct communication with the negative-pressure space 340 without being blocked by other components, such that the suction generated within the negative-pressure space 340 can be utilized more effectively to generate forced convection within the electric control box 8, further improving the airflow volume within the electric control box 8, and achieving a better heat dissipation effect of the flowing airflow on the electric control component 800.
In addition, by utilizing the flowing airflow to carry away heat from the electric control component 800, the heat dissipation effect on the electric control component 800 is good, such that there is no need to set too many heat dissipation holes on the electric control box 8, not only facilitating the processing of the electric control box 8, but also improving the sealing performance of the electric control box 8, achieving better fireproof and rainproof effects. Moreover, even if the electric control component 800 catches fire, the probability of flame propagation can also be effectively reduced.
Thus, the air conditioner according to the embodiments of the present disclosure can utilize the negative pressure formed by the negative pressure space 340 to accelerate the airflow rate within the electric control box 8, such that forced convection can be formed within the electric control box 8, to utilize the airflow to dissipate heat from and cool the electric control component 800, facilitating the improvement of heat dissipation effect on the electric control component 800.

The electric control component 800 is disposed on one side of the first air duct member 35 and located on the lower side of the second air duct member 31. For example, the second air duct member 31 can be disposed on one side of the first air duct member 35 away from the outdoor heat exchanger 22, and the electric control component 800 and the second air duct member 31 can be located on the same side of the first air duct member 35. The second air duct member 31 and the first air duct member 35 are connected to form a cavity for mounting the outdoor fan 34.
In some embodiments, as shown in FIG. 36 and FIG. 38, the first air duct member 35 is provided with a communication hole 3501. The heat dissipation outlet 812 is in communication with the negative-pressure space 340 through the communication hole 3501. In this way, the first air duct member 35 does not isolate the negative-pressure space 340 from the heat dissipation outlet 812, such that the suction generated within the negative-pressure space 340 can act upon the interior of the electric control box 8 through the communication hole 3501 and the heat dissipation outlet 812, thereby producing forced convection within the electric control box 8, to utilize the flowing airflow to carry away heat from the electric control board 820, thereby improving the heat dissipation efficiency of the electric control component 800.
In some embodiments of the present disclosure, as shown in FIG. 41 and FIG. 42, the electric control box 8 is provided with an air outlet portion 811. The air outlet portion 811 protrudes from one side of the electric control box 8 facing the first air duct member 35, and the heat dissipation outlet 812 is formed in the air outlet portion 811. The air outlet portion 811 extends into the communication hole 3501. The air outlet portion 811 can extend along the circumferential direction of the communication hole 3501, and the outer contour of the air outlet portion 811 can fit that of the communication hole 3501. In this way, the air outlet portion 811 is facilitated to extend into the communication hole 3501, such that the relative positioning of the electric control box 8 and the first air duct member 35 can be achieved through the cooperation between the air outlet portion 811 and the communication hole 3501.
In some embodiments, as shown in FIG. 38, the outer sidewall of the air outlet portion 811 can cooperate with the inner wall of the communication hole 3501, facilitating the improvement of the sealing performance between the heat dissipation outlet 812 and the communication hole 3501, preventing air leakage, such that the negative pressure within the negative-pressure space 340 can be more effectively utilized to generate suction within the electric control box 8, to generate the flowing airflow within the electric control box 8, thereby improving the heat dissipation effect on the electric control component 800. Certainly, to facilitate assembly between the electric control box 8 and the first air duct member 35, the outer sidewall of the air outlet portion 811 and the inner wall of the communication hole 3501 may be in clearance fit.
In some embodiments of the present disclosure, as shown in FIG. 36, FIG. 38, and FIG. 39, the air conditioner can further include a first water collection tray 5. The first water collection tray 5 can be disposed on the lower side of the outdoor heat exchanger 22. An air guide rib 3502 is disposed on one side of the first air duct member 35 facing the outdoor heat exchanger 22. The air guide rib 3502 extends along the circumferential direction of the communication hole 3501, and the air guide rib 3502 and the first water collection tray 5 collectively define an air guide duct 3503. The air guide duct 3503 is respectively in communication with the communication hole 3501 and the negative-pressure space 340. By disposing the air guide rib 3502, the structural strength of the first air duct member 35 around the communication hole 3501 can be improved by utilizing the air guide rib 3502. Moreover, the air guide rib 3502 and the first water collection tray 5 define the air guide duct 3503, with a simple structure. The air guide duct 3503 can be utilized to guide air, facilitating the flowing airflow within the electric control box 8 to flow to the negative-pressure space 340.
Specifically, during operation of the air conditioner, the outdoor fan 34 runs, and a negative pressure is generated in the negative-pressure space 340. Under the action of the negative pressure, a flowing airflow is forced to be generated within the electric control box 8. That is, air can flow into the electric control box 8 from the heat dissipation inlet 813. After flowing through the electric control board 820 and carrying away heat from the electric control board 820, the air passes through the heat dissipation outlet 812, the communication hole 3501, and the air guide duct 3503 in sequence to flow into the negative-pressure space 340. Finally, the air can be driven by the outdoor fan 34 to be discharged to the outdoors, thereby improving the heat dissipation efficiency of the electric control board 820.
In some other embodiments, the air conditioner can further include an air guide pipe (not shown in the figures). The air guide pipe is connected to one side of the first air duct member 35 facing the outdoor heat exchanger 22, and the communication hole 3501 is in communication with the negative-pressure space 340 through the air guide pipe. That is, the communication hole 3501 may be in communication with the negative-pressure space 340 through the air guide pipe. That is, one end of the air guide pipe is connected to the communication hole 3501, and the other end of the air guide pipe is in communication with the negative-pressure space 340. In this way, the air guide pipe can be utilized to make the communication hole 3501 in communication with the negative-pressure space 340, and the sealing effect and air-guiding effect are better, such that the flowing airflow within the electric control box 8 can smoothly flow into the negative-pressure space 340, facilitating the improvement of the heat dissipation efficiency of the electric control component 800.
As shown in FIG. 40 and FIG. 41, in some embodiments, the heat dissipation inlet 813 is adjacent to the lower side of the electric control box 8, and the heat dissipation outlet 812 is adjacent to the upper side of the electric control box 8. Thus, air can flow into the electric control box 8 through the heat dissipation inlet 813 on the lower side and then flow out of the electric control box 8 through the heat dissipation outlet 812 on the upper side, that is, air can maintain a “bottom-in and top-out” flow direction, such that the flowing airflow within the electric control box 8 can better flow through the electric control board 820. The contact area between the flowing airflow and the electric control board 820 can be larger, such that the flowing airflow can be utilized to more effectively carry away heat from the electric control board 820, facilitating the improvement of the heat dissipation effect on the electric control board 820.
As shown in FIG. 36 and FIG. 37, in some embodiments, the first air duct member 35 is provided with a ventilating grille 3504. The first air duct member 35 and the housing 1 define a heat dissipation air inlet duct 160. The ventilating grille 3504 is in communication with the outdoor air inlet 114 through the heat dissipation air inlet duct 160, and the heat dissipation inlet 813 is in communication with the ventilating grille 3504. That is, the ventilating grille 3504 is respectively in communication with the heat dissipation inlet 813 and the outdoor air inlet 114. In this way, the first air duct member 35 does not fully block the heat dissipation inlet 813. Outdoor air can flow to the heat dissipation inlet 813 through the heat dissipation air inlet duct 160 and the ventilating grille 3504, such that the outdoor air can flow into the electric control box 8, thereby utilizing the outdoor air to dissipate heat from and cool the electric control board 820 in the electric control box 8.
Specifically, the outdoor air can pass through the outdoor air inlet 114, the heat dissipation air inlet duct 160, the ventilating grille 3504, and the heat dissipation inlet 813 in sequence to enter the electric control box 8. Then, the outdoor air can flow vertically upward and flow out of the electric control box 8 through the heat dissipation outlet 812. Finally, the outdoor air can flow to the negative-pressure space 340 through the air guide duct 3503, and is driven by the outdoor fan 34 to be discharged to the outdoors.
As shown in FIG. 36, FIG. 40, and FIG. 41, in some embodiments, the electric control component 800 can further include a heat dissipator 830. The heat dissipator 830 is connected to the electric control board 820. The heat dissipator 830 is exposed from the heat dissipation inlet 813 and adjacent to the ventilating grille 3504. In this way, the heat dissipator 830 can be closer to the ventilating grille 3504. When outdoor air flows to the heat dissipation inlet 813 through the ventilating grille 3504, it can be ensured that the airflow can pass through the heat dissipator 830, such that the heat from the heat dissipator 830 can be carried away by utilizing the flowing airflow, thereby improving the heat dissipation efficiency of the heat dissipator 830 on the electric control board 820.
As shown in FIG. 40 to FIG. 44, in some embodiments, the heat dissipation inlet 813 can include a first inlet 814. The first inlet 814 is formed in one side of the electric control box 8 facing the first air duct member 35. The first inlet 814 is adjacent to the ventilating grille 3504, and the heat dissipator 830 is exposed from the first inlet 814. That is, the first inlet 814 can be in communication with the outdoor air inlet 114 through the ventilating grille 3504. In this way, outdoor air can flow into the electric control box 8 through the first inlet 814 to dissipate heat from and cool the electric control component 800.
As shown in FIG. 40 to FIG. 44, in some embodiments, the heat dissipation inlet 813 can include a second inlet 815. The second inlet 815 is formed in one side of the electric control box 8 in a width direction. The housing 1 is provided with an air inlet grille 150. The second inlet 815 is adjacent to the air inlet grille 150. For example, the first inlet 814 and the second inlet 815 can be formed in the two adjacent sides of the electric control box 8. In this way, indoor air can pass through the air inlet grille 150 and the second inlet 815 in sequence to flow into the electric control box 8, to dissipate heat from and cool the electric control component 800 by utilizing the indoor air. Thus, by forming the first inlet 814 and the second inlet 815, the air inlet volume of the electric control box 8 can be increased, such that more flowing airflow can be generated within the electric control box 8, facilitating the improvement of heat dissipation efficiency of flowing airflow on the electric control component 800, and achieving a better heat dissipation effect.
As shown in FIG. 36 and FIG. 37, in some embodiments, an air duct air inlet 301 is formed in one side of the air duct assembly 300 facing the outdoor heat exchanger 22, and the heat dissipation outlet 812 is in communication with the air duct air inlet 301. In this way, during operation of the air conditioner, the outdoor fan 34 rotates, such that a negative pressure can be generated at the air duct air inlet 301, that is, suction is generated at the air duct air inlet 301. The suction can suck airflow from the outdoor heat exchanger 22 and the electric control box 8 into the air duct assembly 300 and discharge the airflow to the outdoors. That is, the negative pressure generated at the air duct air inlet 301 can be utilized to generate forced convection within the electric control box 8, such that more air can flow into the electric control box 8 from the heat dissipation inlet 813, and then flow to the air duct air inlet 301 from the heat dissipation outlet 812. The volume of airflow flowing through the interior of the electric control box 8 can be larger, such that the heat from the electric control board 820 can be carried away by utilizing the flowing airflow, preventing the electric control component 800 from reaching excessive temperatures, and achieving a better heat dissipation effect on the electric control component 800.
Moreover, the heat dissipation outlet 812 can be in direct communication with the air duct air inlet 301 without being blocked by other components, such that the suction generated at the air duct air inlet 301 can be utilized more effectively to generate forced convection within the electric control box 8, further improving the airflow volume within the electric control box 8, and achieving a better heat dissipation effect of the flowing airflow on the electric control component 800.
In addition, through this arrangement, by utilizing the flowing airflow to carry away heat from the electric control component 800, the heat dissipation effect on the electric control component 800 is good, such that there is no need to set too many heat dissipation holes on the electric control box 8, not only facilitating the processing of the electric control box 8, but also improving the sealing performance of the electric control box 8, achieving better fireproof and rainproof effects. Moreover, even if the electric control component 800 catches fire, the probability of flame propagation can also be effectively reduced.
Thus, the air conditioner according to the embodiments of the present disclosure can generate the negative pressure at the air duct air inlet 301, and can utilize the negative pressure generated at the air duct air inlet 301 to accelerate the airflow rate within the electric control box 8, such that forced convection can be formed within the electric control box 8, to utilize the airflow to dissipate heat from and cool the electric control component 800, facilitating the improvement of heat dissipation effect on the electric control component 800.
