Abstract

The present disclosure relates to a cleaner, including: a compression assembly coupled to the main body housing and configured to compress the dust stored in the dustbin, and the dustbin may be separably coupled to the main body housing in a state in which the compression assembly is coupled to the main body housing, thereby the dustbin alone can be easily separated from the main body housing to be properly washed.

Description

TECHNICAL FIELD

The present disclosure relates to a cleaner, more particularly, a cleaner which sucks in outside air by a negative pressure, collects dust by separating dust from the sucked air, and reduces a volume of the dust by compressing the collected dust.

BACKGROUND ART

In general, a cleaner refers to an electrical appliance that draws in small garbage or dust by sucking air using electricity and fills a dustbin provided in a product with the garbage or dust. Such a cleaner is generally called a vacuum cleaner.

The cleaners may be classified into a manual cleaner which is moved directly by a user to perform a cleaning operation, and an automatic cleaner which performs a cleaning operation while autonomously traveling. Depending on the shape of the cleaner, the manual cleaners may be classified into a canister cleaner, an upright cleaner, a handy cleaner, a stick cleaner, and the like.

The canister cleaners were widely used in the past as household cleaners. However, recently, there is an increasing tendency to use the handy cleaner and the stick cleaner in which a dustbin and a cleaner main body are integrally provided to improve convenience of use.

In the case of the canister cleaner, a main body and a suction port are connected by a rubber hose or pipe, and in some instances, the canister cleaner may be used in a state in which a brush is fitted into the suction port.

The handy cleaner (hand vacuum cleaner) has maximized portability and is light in weight. However, because the handy cleaner has a short length, there may be a limitation to a cleaning region. Therefore, the handy cleaner is used to clean a local place such as a desk, a sofa, or an interior of a vehicle.

A user may use the stick cleaner while standing and thus may perform a cleaning operation without bending his/her waist. Therefore, the stick cleaner is advantageous for the user to clean a wide region while moving in the region. The handy cleaner may be used to clean a narrow space, whereas the stick cleaner may be used to clean a wide space and also used to a high place that the user's hand cannot reach. Recently, modularized stick cleaners are provided, such that types of cleaners are actively changed and used to clean various places.

as a prior art document, Korean patent no. 10-2020-0031509 is cited. The prior art document provides a cleaner capable of compressing dust inside a dustbin through manipulation of a cleaning apparatus and easily discharging dust from the dustbin. Hereinafter, the prior art document will be described referring to FIGS. 1 and 2. The reference numerals in FIGS. 1 and 2 are only used in the prior art document, and are not applied to the description of the cleaner according to the present disclosure.

FIG. 1 is a perspective view of a cleaner according to the prior art document, and FIG. 2 is a view illustrating an arrangement of a movable part 720′ and a filter portion 20′. Referring to FIG. 2, a means for compressing dust according to the prior art document includes a manipulation part 730′, a transfer part 740′ and the movable part 720′. The manipulation part 730′ is configured to operate when the user presses it with a finger. The movable part 720′ is disposed inside a dustbin, and compresses dust inside the dustbin as it ascends and descends. The transfer part 740′ is configured to deliver an operation of the manipulation part 730′ to the movable part 720′.

When the user manipulates the manipulation part 730′, the manipulation part 730′ descends. As the manipulation part 730′, the transfer part 740′, and the movable part 720′ are fixedly coupled to one another, as the manipulation part 730′ descends, the transfer part 740′ and and the movable part 720′ descend as well.

According to the prior art document, the movable part includes a connecting portion. The connecting portion protrudes radial outward from the movable part and allows the transfer part to be coupled thereto. At this instance, because the connecting portion is exposed to the internal space of the dustbin, a problem such as foreign substances such as strands of hair being trapped on the connecting portion and the like may occur.

MODE FOR INVENTION

Advantages and characteristics of the present disclosure and a method of achieving the advantages and characteristics will be clear by referring to exemplary embodiments described below in detail together with the accompanying drawings. However, the present disclosure is not limited to exemplary embodiment disclosed herein but will be implemented in various forms. The exemplary embodiments are provided by way of example only so that a person of ordinary skilled in the art can fully understand the disclosures of the present disclosure and the scope of the present disclosure. Therefore, the present disclosure will be defined only by the scope of the appended claims. Like reference numerals generally denote like elements throughout the specification.

Hereinafter, exemplary embodiments of the present disclosure with reference to accompanying drawings for explaining the cleaner will be described in detail.

FIG. 1 is a perspective view of a main body of a cleaner according to the prior art document. However, FIG. 1 may be cited to an extent the citation is not in conflict with the cleaner according to the present disclosure.

Referring to FIG. 1, the cleaner 1 according to an embodiment of the present disclosure may include a main body 2. The main body 2 may include a suction part 10 configured to suck in air which contains dust.

Based on a longitudinal axis of the suction part 10, a direction of one side in which the suction part 10 is positioned is defined as a front, and a direction of another side thereof is defined as a rear. Based on the main body of the cleaner illustrated in FIG. 1, an upper side is defined as an upward direction, and a lower side is defined as a downward direction.

The external appearance of the main body is formed by a main body housing 3.

A handle 40 is formed in the main body housing 3.

The suction part 10 is coupled to the front of the main body housing 3.

The dustbin 60 is coupled to the main body housing 3. An opening is formed in a coupling portion between the housing 3 and the dustbin 60, and the housing 3 and the dustbin 60 are communicated with each other.

A portion of a frontal lower part of the main body housing 3 is inserted into the dustbin 60. Since the portion of the frontal lower part of the main body housing 3 is inserted into the opening formed at an upper part of the dustbin 60, the dustbin 60 may be fixedly mounted to the main body housing 3.

A battery 50 is coupled to a bottom part of the main body housing 3. More particularly, the battery 50 is disposed in the bottom part at a rear of the main body housing 3.

A suction motor (not illustrated) is received inside the main body housing 3. The suction motor 20 may generate a negative pressure for sucking outside air into the inside of the main body housing 3.

The suction part 10 has a cylindrical shape with a hollow hole formed inside, is configured to suck in air containing dust, and may provide a suction flow path through which air containing dust may flow. The air containing dust may be guided to the main body 2 through the suction part 10.

The suction part 10 is communicated with an inlet of a cyclone unit 20. Air sucked in a nozzle passes through the suction part 10, and is introduced into the cyclone unit 20 through the inlet.

The main body 2 may further include a suction motor (not illustrated), the cyclone unit 20, the handle 40, and the battery 50.

Here, the suction motor (not illustrated) is configured to generate an air flow (that is, an air current) through which the air containing dust can be introduced into the suction part 10.

The suction motor 20 is disposed inside the housing 3.

The suction motor (not illustrated) is disposed above the dustbin 60. In addition, the suction motor (not illustrated) is disposed above the cyclone unit 20.

The suction motor (not illustrated) may be the BLDC (brushless DC) motor. the

BLDC motor is a type of a DC motor without a brush. Since the BLDC motor does not have a brush, which is a wearable part, the BLDC motor not only has an advantage of having little electrical and mechanical noise, but also has no problem in a high-speed rotation, and generates low rotation noise.

The cyclone unit 20 is communicated with the suction part 10 and is a component to which a principle of a dust collector using a centrifugal force is applied so as to separate dust sucked into an inside of the main body 2 through the suction part 10.

The cyclone unit 20 is coupled to the main body housing 3 or the dustbin 60, and disposed between the suction part and the suction motor.

The cyclone unit 20 is disposed between the suction part 10 and the suction motor (not illustrated). The suction part 10 is disposed upstream of the cyclone unit 20, and the suction motor (not illustrated) is disposed downstream of the cyclone unit 20. The suction part 10 is disposed forward of the cyclone unit 20, and the suction motor (not illustrated) is disposed rearward of the cyclone unit 20.

The handle 40 is configured to be gripped by a user to move the cleaner 1, and is disposed in the opposite direction to the suction part 10 with respect to the cyclone unit 20. The handle 40 has a substantially cylindrical shape, and extends along a longitudinal axis. In addition, the handle 40 may be disposed in a way that an upper part thereof is tilted forward.

An operating part 80 may be disposed on an upper surface of the handle. The user may give instructions to the cleaner using the operating part 80. The instructions may include turning on and turning off, and changes to the entire operation modes including changes to the output of the suction motor.

The battery 50 is configured to supply power to the suction motor (not illustrated). The battery 50 is disposed such that an upper part thereof is adjacent to the handle 40, and a front part thereof is adjacent to a portion of a lower part of an outer circumferential surface of the dustbin 60 which will be described below.

The cleaner 1 may further include the dustbin 60 for storing dust separated in the cyclone unit 20.

The dustbin 60 includes an internal space on the inside. Dust is collected on the internal space.

The dustbin 60 is separably coupled to the main body housing 3. Referring to FIG. 4, the dustbin 60 is separably coupled to a lower end of the main body housing 3.

Referring to FIGS. 3 and 8, the cleaner 1 according to the present disclosure includes a compression assembly 70. The compression assembly 70 is configured to compress dust collected inside the dustbin 60 to reduce a volume of the dust.

While the cleaner 1 is operated, a compression lever 730 and a compression plate 720 are disposed on an upper end of the dustbin 60. While the cleaner 1 is operated, dust is separated from air and is collected while dust spirally moves in the internal space of the dustbin 60.

After stopping the cleaner 1, the compression lever 730 and the compression plate 720 descend and compress dust collected in the internal space of the dustbin 60 to reduce the volume.

The dustbin is separably coupled to the main body housing 3 in a state in which the compression assembly 70 is coupled to the main body housing 3.

The dustbin 60 is coupled to the lower end of the main body housing 3. The compression assembly 70 is coupled to an outer circumferential surface of the main body housing 3, and comes into close contact with the outer circumferential surface of the dustbin 60. The compression assembly 70 is not coupled to the dustbin 60, and thus, the dustbin 60 may be separated from the main body housing 3 in a state in which the compression assembly 70 is coupled to the main body housing 3.

The compression assembly 70 includes a compression lever housing 710, the compression plate 720, the compression lever 730, and compression arms 741 and 744.

Referring to FIGS. 5 and 9, the cleaner 1 according to the present disclosure includes the compression lever housing 710. The compression lever housing 710 forms an external appearance of the compression assembly 70, forms a space inside, and is configured to store components configuring the compression assembly 70.

The compression lever housing 710 is disposed on the outside of the compression arm arrangement portion 310, and is mounted in the main body housing 3. The compression lever housing 710 covers the compression arm arrangement portion 310.

An inside of the compression lever housing 710 is open. The inside of the compression lever housing 710 faces the outer circumferential surface of the dustbin 60.

The inside of the compression lever housing 710 forms a curved surface. Therefore, the inside of the compression lever housing 710 comes into close contact with the outer circumferential surface of the dustbin 60 and does not form a gap.

The compression lever housing 710 is formed elongated along the compression arm arrangement portion 310.

A slit (not illustrated) parallel to the compression arm arrangement portion 310 is formed in the compression lever housing 710. The slit of the compression lever housing 710 is formed elongated along the compression arm arrangement portion 310. The slit of the compression lever housing 710 is elongated along the compression arm arrangement portion 310.

Referring to FIGS. 5 and 9, the cleaner 1 according to the present disclosure includes the compression plate 720. The compression plate 720 is disposed inside the dustbin 60, and is configured to compress dust collected inside the dustbin 60 to reduce the volume of the dust.

The compression plate 720 is disposed in the internal space of the dustbin 60, and ascends and descends in the longitudinal direction of the dustbin 60.

The compression plate 720 is formed in a shape similar to a donut.

An inner circumferential surface of the compression plate 720 comes into close contact with an inner circumferential surface of the cyclone unit 20. Therefore, when the compression plate 720 descends, dust attached to the cyclone unit 20 may be swept.

Referring to FIGS. 5 and 9, the cleaner 1 according to the present disclosure includes the compression lever 730. The compression lever 730 receives a force from the user and transfers the force to the compression plate 720 so as to ascend and descend the compression plate 720.

The compression lever 730 is manipulated by the user, and when manipulated, the compression lever 730 ascends and descends the compression plate 720.

The compression lever 730 is disposed in the compression lever housing 710, and is connected to the compression plate 720 through the compression arms 741 and 744.

The compression lever 730 is disposed on an outer side surface of the compression lever housing 710. The compression lever 730 ascends and descends along the slit of the compression lever housing 710.

The compression arms 741 and 744 are configured to deliver a movement of the compression lever 730 to the compression plate 720.

One side of each of the compression arms 741 and 744 are connected to the compression plate 720, and another side thereof is connected to the compression lever 730.

The compression arms 741 and 744 extend in the longitudinal direction of the dustbin 60. Referring to FIGS. 5 and 9, the compression arms 741 and 744 extend upward from the compression plate 720.

The compression arms 741 and 744 are not exposed to the internal space of the dustbin 60. Referring to FIGS. 5 and 9, the compression arms 741 and 744 are coupled to an upper surface of the compression plate 720. At this instance, the internal space of the dustbin 60 is specified by an internal circumferential surface of the dustbin 60 and a lower surface of the compression arms 741 and 744, and the compression arm is not exposed to the internal space of the dustbin 60. With this configuration, there is an effect that foreign substances such as strands of hair are not trapped in the compression arms 741 and 744 or a connecting portion between the compression arms 741 and 744 and the compression plate 720.

The main body housing 3 may include the compression arm arrangement portion 310.

The compression arm arrangement portion 310 is formed to be recessed radially inward from one side of an outer circumferential surface of the main housing 3, and at least a portion of the compression arms 741 and 744 is disposed in the compression arm arrangement portion 310.

The compression arm arrangement portion 310 shields the compression arms 741 and 744 from the outside.

The compression arm arrangement portion 310 is disposed on an upper side of the dustbin 60. With this configuration, it is possible to prevent the compression arms 741 and 744 from being exposed to the dustbin 60, and secure a sufficient stroke distance of the compression arms 741 and 744 and the compression plate 720 at the same time.

The main body housing 3 may further include a step 311 and a compression arm insertion hole 312.

The step 311 is disposed at a lower end of the compression arm arrangement portion 310, and is formed in a direction intersecting a longitudinal direction. For example, referring to FIG. 5, the step 311 extends radially outward of the dustbin 60.

An upper surface of the step 311 may be in contact with a compression lever connecting member 742 or a connecting portion 7442 of the compression arm. This configuration may serve as a stopper which prevents the compression plate 720 from descending further when the compression assembly 70 moves to a threshold descending position.

The compression arm insertion hole 312 is formed in the step 311, and at least a portion of the compression arms 741 and 744 is inserted into the compression arm insertion hole 312. The compression arms 741 and 744 are coupled to the compression plate 720 at a lower side of the compression arm insertion hole 312, and are coupled to the compression lever 730 at an upper side of the compression arm insertion hole 312.

Referring to FIG. 5, according to a first embodiment, the compression assembly 70 may further include the compression lever connecting member 742.

The compression arm 741 extends in the longitudinal direction of the dustbin 60. One end of the compression lever connecting member 742 is coupled to an end of the compression arm 741 and extends in a radial direction of the dustbin 60, and another end thereof is coupled to the compression lever 730.

Referring to FIG. 5, the compression arm 741 extends upward from the compression plate 720, and the compression lever connecting member 742 extends radially outward from an upper end of the compression arm 741, and thus, the compression lever connecting member 742 is formed in an L-shape as a whole.

The compression lever connecting member 742 may extend in a circumferential direction of the dustbin 60.

According to the first embodiment, when the compression assembly 70 descends to the threshold descending position, the compression lever connecting member 742 is stopped by the step 311 of the compression arm arrangement portion 310.

Referring to FIG. 9, the compression arm 744 may be divided into a vertical portion 7441 and a connecting portion 7442 according to a second embodiment.

One end of the vertical portion 7441 is coupled to the compression plate 720, and extends in the longitudinal direction of the dustbin 60. For example, referring to FIG. 9, a lower end of the vertical portion 7441 is coupled to an upper surface of the compression plate 720, and extends upward.

One end of the connecting portion 7442 is coupled to another end of the vertical portion 7441, extends in the radial direction of the dustbin 60, and another end thereof is coupled to the compression lever 730. For example, referring to FIG. 9, the connecting portion 74442 extends radially outward of the dustbin 60 from an upper end of the vertical portion 7441, and an outer end thereof is coupled to the compression lever 730.

According to the second embodiment, the compression arm 744 may be formed in an L-shape.

According to the second embodiment, when the compression assembly 70 descends to the threshold descending position, the connecting portion 7442 is stopped by the step 311 of the compression arm arrangement portion 310.

Referring to FIG. 8, the cleaner according to the second embodiment may further include a compression arm housing 320.

The compression arm housing 320 is disposed in the compression arm arrangement portion, forms a space inside, and receives the compression arm therein to separate the compression arm from the outside.

The compression arm housing 320 receives the compression arm 744 to separate the compression arm 744 from the outside, helps to form sealing between the compression arm insertion hole 312 and the compression arm 744, and guides ascending and descending of the compression arm 744.

A slit 321 extending in a direction in which the compression plate 720 and the compression arm 744 ascend and descend may be formed in the compression arm housing 320. At this instance, the connecting portion 7442 of the compression arm penetrates the slit 321 of the compression arm housing 320.

Although not illustrated in FIG. 5, the compression arm housing 320 may be disposed in the compression arm arrangement portion 310 of the cleaner according to the first embodiment.

Referring to FIGS. 9 and 10, the cleaner 1 according to the present disclosure includes a sealer 750. The sealer 750 is configured to cover the compression arm arrangement portion 310 and seal the slit of the compression lever housing 710.

The sealer 750 is disposed in the slit of the compression lever housing 710, and extends along the compression arm arrangement portion 310.

Although not illustrated in FIG. 5, the sealer 750 may be disposed in the compression arm arrangement portion 310 of the cleaner according to the first embodiment.

Referring to FIG. 10, the sealer 750 includes a fixing portion 751 and a deformation portion 752.

The deformation portion 752 is supported by the fixing portion 751, seals the slit of the compression lever housing 710, and forms a gap as at least a portion thereof is deformed.

The deformation portion 752 is formed in a cylindrical shape with a hollow hole provided therein. The deformation portion 752 extends in the longitudinal direction of the dustbin 60. An upper surface and a lower surface of the deformation portion 752 may be open.

The deformation portion 752 may strongly seal the gap as at least a portion thereof is deformed. Referring to FIG. 10, a front end of the deformation portion 752 may protrude toward a front of the compression lever housing 710. Therefore, when the compression lever housing 710 is mounted in the dustbin 60, a front end of the deformation portion 752 may come into close contact with the dustbin 60 while being slightly depressed rearward, thereby more strongly sealing the slit of the compression lever housing 710 from the outside.

Referring to FIG. 10, one side surface of the deformation portion 752 comes into close contact with the compression arm 744. At this instance, the one side surface of the deformation portion 752 is slightly pushed inward to come into close contact with the compression arm 744, thereby removing a gap between the deformation portion 752 and the compression arm 744. In particular, when the compression arm 744 descends, as the deformation portion 752 is deformed at a lower end of the compression arm 744, a gap in which the compression arm 744 can move is formed, and the gap for the compression arm 744 is removed as the deformation portion 752 is restored at an upper end of the compression arm 744, thereby a sealed state may be maintained between the sealer 750 and the compression arm 744.

In more detail, according to the first embodiment, the compression assembly 70 may include the compression arm 741 and the compression lever connecting member 742. In this case, the one side surface of the deformation portion 752 may come into close contact with the compression lever connecting member 742.

Unlike the first embodiment, according to the second embodiment, the compression arm 744 may be divided into the vertical portion 7441 and the connecting portion 7442. In this case, the one side surface of the deformation portion 752 may come into close contact with the connecting portion 7442.

The fixing portion 751 is fixed to the compression lever housing 710. The fixing portion 751 protrudes outward from an outer circumferential surface of the deformation portion 752. The fixing portion 751 extends along the longitudinal direction of the dustbin 60. The fixing portion 751 may be formed in a plate shape.

An end of the fixing portion 751 may be fitted into and coupled to the compression lever housing 710. An elongated groove may be formed in the compression lever housing 710, and as the fixing portion 751 is fitted into and coupled to the groove, the sealer 750 may be installed in the compression lever housing 710.

The fixing portion 751 may consist of a first extension 751a and a second extension 751b.

The first extension 751a extends along the outer circumferential surface of the dustbin 60 from the deformation portion. The first extension 751a may extend along the longitudinal direction of the dustbin 60. That is, the first extension 751a may extend in a direction of the outer circumferential surface of the dustbin 60, and may be formed in a shape of a plate extending along the longitudinal direction of the dustbin 60.

The first extension 751a may form a curved surface along the outer circumferential surface of the dustbin 60. Alternatively, the first extension 751a may form a plane.

The second extension 751b extends in a direction of the compression lever housing 710 from an end of the first extension 751a, and at least a portion of the second extension 751b is inserted into the groove formed in the compression lever housing 710. The second extension 751b may extend rearward from an end of the first extension 751a. The second extension 751b is fitted into and coupled to the groove formed in the compression lever housing 710, thereby fixing the sealer 750 to the compression lever housing 710. The second extension 751b may be formed elongated vertically along the longitudinal direction of the dustbin 60.

Referring to FIG. 10, the sealer 750 is provided in plural number, and the plurality of sealers 750 is disposed on left and right sides, respectively, about the compression lever housing 710.

Hereinafter, the functions and effects of the cleaner 1 according to the present disclosure described above will be described.

Before operation, the compression plate 720 is disposed in a threshold ascending position, at a lower end of the main body housing 3. When the user presses the compression lever 730 downward, the compression lever 730, the compression arms 741 and 744, and the compression plate 720 descend together, thereby compressing dust inside the dustbin 60. When the user takes hands off from the compression lever 730, the compression lever 730, the compression arms 741 and 744, and the compression plate 720 ascend together by a spring to return to their original positions.

According to the present disclosure, the dustbin 60 is coupled to the lower end of the main body housing 3, and the compression assembly 70 is coupled to the outer circumferential surface of the main body housing 3. At this instance, the dustbin 60 is separably coupled to the main body housing 3 in a state in which the compression assembly 70 is coupled to the main body housing 3. With this coupling structure, in a state in which the compression assembly 70 is coupled to the main body housing 3, there is an effect that the dustbin 60 can be properly washed because the dustbin 60 alone can be easily separated from the main body housing 3.

According to the present disclosure, one side of each of the compression arms 741 and 744 is coupled to the upper surface of the compression plate 720, and another side thereof is connected to the compression lever 730. With this configuration, there is an effect that foreign substances such as strands of hair are not trapped by the compression assembly 70 because the compression arms 741 and 744 are not exposed to the internal space of the dustbin 60.

The cleaner may include the compression arm arrangement portion 310 recessed radially inward from one side of the outer circumferential surface of the dustbin 60 and allowing at least a portion of the compression arms 741 and 744 to be disposed therein. At this instance, the dustbin 60 may include the step 311 disposed at the lower end of the compression arm arrangement portion 310 and formed in the direction intersecting the longitudinal direction, and the compression arm insertion hole 312 allowing at least a portion of the compression arms 741 and 744 to be inserted thereinto.

According to the present disclosure, the step 311 disposed in the radial direction of the dustbin 60 is disposed at the lower end of the compression arm arrangement portion 310. When the compression plate 720 descends to the threshold descending position, it is possible to prevent the compression plate 720 from descending further because the connecting portion 7442 of the compression arm or the compression lever connecting member 742 is stopped by the step 311.

According to an embodiment of the present disclosure, the cleaner according to the embodiment may further include the compression arm housing 320 configured to receive the compression arm 744 to separate the compression arm from the outside. Accordingly, the cleaner according to the embodiment may improve sealability between the compression arm insertion hole 312 and the compression arm 744 while separating the compression arm 744 from the outside at the same time, and may guide ascending and descending of the compression arm 744.

According to an embodiment of the present disclosure, the cleaner according to the embodiment may further include the sealer 750 disposed in the slit of the compression lever housing 710. Accordingly, it is possible to improve sealability between the dustbin 60 and the compression assembly 70.

Although some embodiments have been illustrated and described above, this specification is not limited to the aforementioned specific embodiments, and a person having ordinary skill in the art to which this specification pertains may modify the present disclosure in various ways without departing from the gist of the claims. Such modified embodiments should not be individually interpreted from the technical spirit or prospect of this specification.
