The first filtering part 5 may include a filtering part body 51, 53, 57, and 58 inserted into the filter mounting hole 113 and the duct through-hole 34 and positioned between the second filtering part 8 and the heat absorbing part 41 and a filter 531, 551, and 571 provided in the filtering part body to filter the fluid (e.g., air and water) moving to the heat absorbing part 41 and the water collection body 371.
The filtering part body may be provided in various shapes according to the shape of cross-sections (e.g., Y-Z plane and X-Z plane of the connection duct 35) of the connection duct 35, and
In this case, the filtering part body may be provided to include a front surface 51 in a shape capable of closing the duct through-hole 34, a rear surface 53 positioned between the front surface and the heat absorbing part 41, a bottom surface 55 provided to connect the front surface and the rear surface, a first side surface 57 forming a left side surface of the filtering part body, and a second side surface 58 forming a right side surface of the filtering part body.
The front surface 51 may be provided with a lock 513 detachably coupled to a lock fastening portion 16 provided to the cabinet. The lock 513 may be provided as a bar rotatably coupled to the front surface 51 of the filtering part body, and the lock fastening portion 16 may be provided to form a recess in which a free end of the bar is accommodated. Preferably, the lock 513 may be provided at both confronting sides of the front surface 51 facing each other and the lock fastening portion 16 may be provided at both confronting sides of the filter mounting hole 113.
A handle 511 may be further provided on the front surface 51 to facilitate the filtering part body to be inserted into or separated from the connection duct 35.
The rear surface 53 and the bottom surface 55 may be provided with a first filter 531 and a second filter 551 that filter the fluid (e.g., air and water) introduced into the filtering part body, respectively. The rear surface 53 is provided with a rear surface through-hole allowing the inside of the filtering part body to communicate with the inner space of the duct 3A, and the first filter 531 is provided in the rear surface through-hole. The bottom surface 55 is provided with a bottom surface through-hole through which the inside of the filtering part body communicates with the inner space of the duct 3A, and the second filter 551 is provided in the bottom surface through-hole. Accordingly, the first filter 531 becomes a means for filtering the fluid (e.g., air and water) supplied to the heat absorbing part 41, and the second filter 551 becomes a means for filtering the fluid supplied to the water collection body 371.
The first side surface 57 and the second side surface 58 may be provided to connect the front surface 51, the rear surface 53, and the bottom surface 55.
The first filtering part 5 having the above-described structure may be provided to communicate with the exhaust duct 31 through the upper surface or the second side surface 58 of the filtering part body.
The first filter 531 may be inclined from 90 degrees to 100 degrees toward the front surface of the heat absorbing part 41 with respect to the bottom surface 55 of the filtering part body. That is, when water is sprayed to the first filter 531 through the cleaning unit 6 to be described later, foreign substances remaining in the first filter may be easily moved to the bottom surface 55.
The second filter 551 may be inclined downward from the front surface 51 toward the first filter 531 by an angle of 10 degrees to 20 degrees (e.g., the second filter may be inclined upward by an angle of 10 to 20 degrees from a lower end of the first filter toward a direction in which the filter mounting hole is located). When the second filter 551 is inclined downward toward the first filter 531, a connection point between the first filter 531 and the second filter 551 is the lowest point in the space provided by the first filtering part, and thus the foreign substance 1 of the first filtering part 5 may be concentrated on a connection point between the first filter 531 and the second filter 551. When the foreign substances are concentrated on the connection point between the first filter 531 and the second filter 551, a user may more easily remove foreign substances in the first filtering part 5.
Yet, when foreign substances are concentrated at the connection point between the first filter 531 and the second filter 551, it may happen that it takes a long time for the water sprayed through the cleaning unit 6 to be discharged to the water collection body 371. To solve this problem, the first side surface 57 may further include a bypass hole allowing the inside of the first filtering part 5 to communicate with the collecting body 371 and a third filter 571 provided in the bypass hole.
The bypass hole and the third filter 571 may be provided at a position higher than the uppermost end of the second filter 551 and lower than the uppermost end of the first filter 531. Therefore, the laundry treating apparatus may minimize a phenomenon in which water sprayed to the first filtering part 5 cannot be recovered to the water collection body 371 by the foreign substances remaining in the first filtering part 5.
Meanwhile, the drying device 20 may further include a cleaning unit 6 for cleaning the first filtering part 5 using water stored in the water collection body 371. That is, the water stored in the water collection body 371 may be separately collected to the water storage unit 7 or may be selectively moved to the cleaning unit 6.
The cleaning unit 6 may be provided as a means for cleaning at least one of the first filter 531, the second filter 551, the third filter 571, and the heat absorbing part 41 by spraying the water stored in the water collection body 371 to the first filtering part 5. The cleaning unit 6 may include a spray unit 65 provided in the duct 3A to supply water to the first filtering part 5 and a cleaning pump 61 to move the water stored in the water collection body 371 to the spray unit 65.
The cleaning pump 61 may be connected to the water collection body 371 through a first connection pipe 611, and may be connected to the spray unit 65 through a second connection pipe 613. If the laundry treating apparatus is provided with only one cleaning pump 61 to move the water of the water collection body 371 to the spray unit 65 and the water storing unit 7, the drying device 20 may further include a flow path switching unit 63. In this case, the flow path switching unit 63 may be connected to the cleaning pump 61 through the second connection pipe 613, the spray unit 65 may be connected to the flow path switching unit 63 through the spray supply pipe 631, and the water storage unit 7 may be connected to the flow path switching unit 63 through the water storage unit supply pipe 633.
In this case, the water storage unit supply pipe 633 should be provided to connect the nozzle 722a and the flow path switching unit 63.
The flow path switching unit 63 is provided with a valve that controls the opening and closing of the spray supply pipe 631 and the opening and closing of the water storage unit supply pipe 633. Accordingly, the drying device 20 may supply the water stored in the water collection body 371 to the spray unit 65 by controlling the valve provided in the flow path switching unit 63, or may supply the water to the water storage unit 7.
According to the example shown in the drawing, the spray unit 65 includes a duct through-hole 651 passing through the connection duct 35 and having the spray supply pipe 631 connected thereto, a first guide 653 for guiding the water supplied from the duct through-hole to the first filter 531, and a second guide 655 for guiding at least a portion of the water supplied through the first guide 653 to the front surface of the heat absorbing part 41. In this case, the second guide 655 may be provided as a means for allowing water to be supplied to the front surface of the heat absorbing part 41 through the first filter 531. That is, when the first filtering part 5 is fixed to the connection duct 35, the first filter 531 may be disposed between the first guide 653 and the second guide 655, and the second guide 655 may be provided as an inclined surface inclined downward from the upper surface of the connection duct 35 toward the first filter 531.
The first guide 653 may further include a guide through-hole 654. The guide through-hole 654 may be a hole provided to perforate the first guide 653, and the water introduced into the duct through-hole 651 may be supplied to a front area of the heat absorbing part 41 through the guide through-hole 654. The front area of the heat absorbing part refers to an area located in a direction toward the first filter 531 with respect to a vertical line passing through the center of the heat absorbing part 41.
Meanwhile, the laundry treating apparatus of the present disclosure preferably includes a water collection unit water level sensing unit 91 that measures a water level of the water collection body 371 and transmits the measured water level to the controller. When the water collection unit water level sensing unit 91 is provided, the laundry treating apparatus may determine a time point at which the water stored in the water collection body 371 is moved to the storage body 72, thereby preventing the water of the water collection body 371 from flowing back to the connection duct 35.
The water collection unit water level sensing unit 91 may be provided as any device capable of sensing a water level inside the water collection body 371, and
A dryness sensing unit may be provided to the drying device 20 so that an operation stop timing point of the heat exchange unit 4 may be determined by determining a dryness of laundry. The dryness sensing unit may include at least one of an electrode sensor 95 provided to be in contact with laundry to measure an amount of moisture contained in the laundry and a humidity sensor for measuring a humidity of air introduced into the duct 3A from the drum 2.
The electrode sensor may include a first electrode 951 and a second electrode 953 that may come in contact with the laundry inside the drum body 21 by being fixed to the first fixing body 171. As the degree of dryness increases, the amount of moisture contained in the laundry may be reduced (the electrical resistance of the laundry increases). Hence, the drying device 20 may determine the dryness of the laundry by observing the electrical resistance measured when the two electrodes 951 and 953 are connected through the laundry. Meanwhile, as the drying degree of the laundry increases, the amount of moisture contained in the air introduced into the duct 3A is reduced, and thus the drying device 20 may determine the dryness of the laundry by observing the humidity of the air introduced into the duct 3A through the humidity sensor.
In addition, the drying device 20 may further include a temperature sensing unit 96 for measuring a temperature of the air introduced into the duct 3A. The temperature sensing unit 96 may be fixed to an upper surface of the connection duct 35 to be positioned between the first filter 531 and the second filter 551.
The drive unit 28 may be directly fastened to a backside of the drying drum 2A. The drying drive unit 28 may be disposed on the second support portion 19 to directly rotate the drying drum 2A.
The drying drive unit 28 may include a stator supported by the second support portion 19, a rotor rotated by the stator, and a rotating shaft.
The drying drive unit 28 may be separately coupled to a decelerator 28A, and the decelerator 28A may be coupled to the center of the backside of the drying drum 2A to rotate the drying drum 2A.
Accordingly, the decelerator 28A may increase torque while reducing the RPM of the rotating shaft.
A steam unit 200 may be fixed to the first support portion supporting the front panel 11 or the drum 2 for space utilization. In addition, the steam unit 200 may be provided adjacent to a corner of the cabinet 1.
An internal supply unit 400 may include a water tank 420 for storing water, a water pump 430 providing power for supplying the water stored in the water tank 420 to the steam unit 200, and a tank housing 410 providing a space in which the water pump 430 and the water tank 420 are installed.
The tank housing 410 may be provided in a box shape with an open top surface, the water pump 430 is disposed on a front side of the cabinet 1, and the tank housing 410 may extend along front and rear sides of the cabinet 1 so that the water pump 430 may be disposed on the rear side of the cabinet 1.
The tank housing 410 may include a tank mounting portion 411 on which the water tank 420 is detachably seated and a pump mounting portion 412 on which the water pump 430 may be mounted. The tank mounting portion 411 and the pump mounting portion 412 may be provided in recess shapes to prevent water leaking from the water tank 420 or the water pump 430 from leaking to the drying drum 2A and the like.
In addition, the tank housing 410 may further include a partition wall 413 partitioning the tank mounting portion 411 and the pump mounting portion 412. Accordingly, the water tank 420 may be easily mounted on and separated from the tank housing 410. The partition wall 413 may play a role as a collector to prevent the remaining water in the tank mounting portion 411 or the remaining water on the pump mounting portion 412 from moving to other places.
An extension pipe 416 that allows the water tank 420 and the water pump 430 to communicate with each other may be installed on the partition wall 413. A valve system may be installed at the extension pipe 416 to prevent water leakage even when the water tank 420 is separated from the tank mounting portion 411.
The extension pipe 416 may extend from the partition wall 413 toward the water pump 430 or the water tank 420.
Meanwhile, the tank housing 410 may be formed such that the pump mounting portion 412 is disposed closer to the steam unit 200 than the tank mounting portion 411. Accordingly, a flow path for a supply from the water tank 420 to the steam unit 200 may be simplified.
The tank housing 410 may be formed such that the tank mounting portion 411 and the pump mounting portion 412 are disposed along the front-rear direction of the cabinet.
A water supply unit 300 may include a coupling part capable of fixing the tank housing 410 to at least one of a support bar 440 and one side surface of the cabinet.
Meanwhile, a drying drum 2A rotating inside the drying cabinet 1 is provided. Therefore, the configuration disposed inside the cabinet 1 needs to be spaced apart from the drying drum 2A. Therefore, it is necessary to prevent the water supply unit 300 and the steam unit 200 from being in contact with the drum 2. For example, a steam guide pipe 230 supplying steam from the steam unit 200 to the drum 2, a direct water pipe 510 supplying water to the steam unit 200, and the like need to be blocked from coming in contact with the drying drum 2A.
Meanwhile, it is necessary to support not only the water tank 420 and the water pump 430 but also the weight of the water accommodated in the water tank 420.
Therefore, the laundry treating apparatus according to the present disclosure may include a support bar 440 supporting the steam unit 200 and the water supply unit 300 to prevent the steam unit 200 and the water supply unit 300 from being in contact with the drum, the support bar 440 supporting the steam unit 200 and the water supply unit 300 within the drying cabinet.
The support bar 440 may be provided to support at least one portion of the steam unit 200 or at least one portion of the water supply unit 300. In addition, the support bar 440 may fix the tank housing 410 to the drying cabinet or support the same.
Both ends of the support bar 440 may be provided in a bar shape coupled to a drying front panel 11 and a drying rear panel 12. Accordingly, the support bar 440 may not only support the weight of the tank housing 410, but also fix the drying front panel 11 and the drying rear panel 12. The support bar 440 may be coupled to the drying front panel 11 and the drying rear panel 12 in a manner of being spaced apart from a drying side panel 14 by a predetermined distance. Meanwhile, both ends of the support bar 440 may be coupled to the cabinet 1, and the rest of the support bar 440 may be disposed at a position lower than an upper portion of a side surface of the cabinet 1. Accordingly, the support bar 440 may be prevented from interfering with the upper panel 13 by being spaced apart from the upper panel 13. In addition, a space capable of supporting some configurations of the water supply unit 300 and the steam unit 200 may be formed between the support bar 440 and the upper panel 13.
Owing to the support bar 440, the width of the tank housing 410 may be prevented from being excessively extended.
Although not shown, the tank housing 410 may further include a mounting sensor capable of sensing whether the water tank 420 is mounted on an inner surface of the tank housing 410. The mounting sensor may include a weight sensor and be provided to distinguish heaviness/lightness of the weight.
The mounting sensor may be connected to the drying control panel PA to transfer information indicating whether the water tank 420 is mounted as well as information on the quantity of water accommodated in the water tank 420.
The internal supply unit 400 may include a pump discharge pipe 433 that discharges water from the pump housing 430 to the steam unit 200.
The external supply unit 500 may include a direct water valve 520 seated on the second support portion 19A or the drying rear panel 12 and a direct water pipe 510 provided to supply water from the direct water valve 520 to the steam unit 200.
The direct water pipe 510 may extend from the drying rear panel 12 to the steam unit 200, and the direct water valve 520 may be provided to open/close the direct water pipe 510. The direct water pipe 510 may extend from the direct water valve 520 to the steam generator 210 across the support bar 440. In this case, at least one portion of the direct water pipe 510 may be supported by the support bar 440 to be prevented from coming into contact with the drying drum 2A.
The support bar 440 may be disposed between the direct water valve 520 and the water tank 430.
In addition, the direct water valve 520 may be seated on the drying rear panel 12 or the second support portion 19A to be exposed externally, and the direct water pipe 510 may be provided to extend from the direct water valve 520 toward the steam unit 200. Accordingly, the external supply unit 500 may supply water to the steam unit 200 in a direct water manner from an external water supply source.
The steam unit 200 may be provided to receive water from the external supply unit 500 and the internal supply unit 400, respectively. Yet, when the steam unit 200 is provided to receive water through each pipe, a steam unit 200 having a different shape should be manufactured, and thus a flow path and a control method may be complicated.
To this end, the laundry treating apparatus of the present disclosure may further include a combining junction unit 600 coupling the direct water pipe 510 and the pump discharge pipe 433 so that the direct water pipe 510 and the pump discharge pipe 433 are combined to form a junction. The combining junction unit 600 may be provided to collect both water stored in the internal supply unit 400 and water supplied from the external supply unit 500 in a direct water manner.
In addition, the combining junction unit 600 may be provided to transfer the supplied water to the steam unit 200. The combining junction unit 600 may be provided as a three-way valve, or may be provided in the shape of a combined junction pipe in which three pipes are coupled.
When the combining junction unit 600 is provided in a tubular shape, the external supply unit 500 and the internal supply part 400 may be provided with check valves to prevent backflow. Specifically, the direct water pipe 510 may be provided with a direct water check valve 511 provided to open the direct water pipe 510 in one direction, and the pump discharge pipe 433 may be provided with a discharge check valve 434 provided to open the pump discharge pipe 433 in one direction.
In addition, a check valve may be provided to each of the pump discharge pipe 433 and the direct water pipe 510. The external supply unit 500 may include an external check valve, and the internal supply unit 400 may include an internal check valve.
Accordingly, the water supplied to the direct water pipe 510 may be prevented from flowing back to the water pump 430, and the water supplied to the pump discharge pipe 433 may be prevented from flowing backward to the direct water valve 510.
Meanwhile, when the combining junction unit 600 is provided as a valve or a combining junction pipe, the combining junction unit 600 has a significant weight of its own. In addition, when water passes through the combining junction unit 600, a significant weight may be applied to the combining junction unit 600.
Therefore, the combining junction unit 600 may be provided in a manner of being mounted on the support bar 440.
The combining junction unit 600 and the support bar 400 may be coupled to each other by a separate fixing member to prevent the combining junction unit 600 from being separated from the support bar 400. Since the combining junction unit 600 is seated on the support bar 400, the positions of the direct water pipe 510 and the pump discharge pipe 433 may be stably fixed.
Meanwhile, the steam unit 200 may include a water guide pipe 220 connected to the combining junction unit 600 to be supplied with water of the water supply unit 300, a steam generator 210 generating steam by being supplied with water from the water guide pipe 220, and a steam guide pipe 230 guiding the steam generated from the steam generator 210 to the drying drum 2A or the duct 3A.
The steam generator 210 may be provided below the drying drum 2A to be stably supplied with water from the water supply unit 300 by gravity, and the generated steam may be stably moved to the drying drum 2A owing to a density difference.
The steam guide pipe 230 may be provided to communicate with a gasket provided in front of the drying drum 2A or the first support portion. Accordingly, the steam guide pipe 230 may stably supply steam into the drying drum 2A without coming in contact with the drying drum 2A.
Meanwhile, the tank housing 410 may be provided with a mounting sensor capable of sensing whether the water tank 420 is mounted. For example, the mounting sensor may be provided as a pressure sensor or the like.
In addition, a water level sensor capable of sensing the water level of the water tank 420 may be further provided. For example, the water level sensor may be provided as a weight sensor. The mounting sensor or the water level sensor may also be controlled by the control panel 820, and may be provided to transmit a signal to the control panel 820.
Meanwhile, the control panel P may indirectly recognize the water level of the water tank 420 by temporarily driving the water pump 430 and sensing a load added to the water pump 430.
The water storage tank 72 may have a significantly larger volume than the water tank 430, and may be disposed in a manner of being spaced apart from the water tank 430 to prevent user's confusion as to the water tank 430.
The water tank 430 and the steam unit 200 may be disposed between the support bar 440 and one side surface of the cabinet, and the water storage tank 72 may be disposed between the support bar 440 and the other side surface of the cabinet.
Since the water tank 430 is coupled to the tank mounting portion 411, it can be seen that the tank mounting portion 411 is also disposed between the support bar 440 and the one side surface of the cabinet.
As a result, the support bar 440 may be disposed between the water storage tank 72 and the steam generator 210, and may be disposed between the water storage tank 72 and the water tank 430.

In order to increase the fastening force of the mounting body 831, the accommodation body fastening portion 833 may be provided with an upper fastening portion positioned at a higher point than the seating surface 832 and a lower fastening portion positioned at a lower point than the seating surface 832. Unlike the drawings, the accommodation body fastening portion 833 may be provided on each of the left and right sides of the seating surface.
A window P85 may be further provided to the accommodation body 81a to prevent water and foreign substances from being introduced into the display P84 and the second circuit board P82.
Preferably, the window P85 is fixed to at least one of the accommodation body 81a and the mounting body 831 to close the accommodation body through-hole 812. The window P85 may be formed of a material having a transparency such that the information displayed on the display P84 and the light emitted from the lamp 821 can be checked externally.
When the window P85 is fixed to the mounting body 831, a cover fixing protrusion 851 protruding toward the mounting body 831 may be provided to the window P85, and a fixing protrusion fastening portion 834 to which the cover fixing protrusion 851 is coupled may be provided to the mounting body 831.
The second circuit board P82 may also be fixed to the mounting body 831. That is, the mounting part P83 may include a protrusion 838 protruding from the mounting body 831 toward the second circuit board 82, and the second circuit board 82 may be provided with a protrusion through-hole 823 into which the protrusion 838 is inserted.
In addition, a cover sheet 853 for lowering the transparency of the cover may be further provided to the window P85. The transparency of the cover sheet is preferably set to an extent that the inside of the mounting space 811 is difficult to be checked from the outside (e.g., the transparency of the cover sheet is set to be lower than the transparency of the cover). The cover sheet 853 may be fixed to the surface of the window P85, and a text or symbol H may be provided to an area onto which the lamp through-hole 835 is projected in the cover sheet.
Meanwhile, in the mounting part P83, the lamp through-hole 835 corresponding to the input area D3 of the lamp through-hole 835 may provide a user with a signal for pressing the input area D3.
The selector R may be provided inside the display unit P8. Specifically, the selector R may be provided as a configuration of the display unit P8, and may be provided to the display unit P8 to be disposed inside the manipulation unit P7.
Accordingly, it can be seen that the display unit P8 includes the selector R for receiving a determination command for determining the state information displayed on the display P84. Since the determination command determined by the selector R varies according to the state information, the selector R may correspond to a variable input unit.
For example, when selection information of a course and option is displayed on the display P84, the selector R may be configured to input a determination command for selecting or determining the course and option. In addition, when a guide text is displayed on the display P84, the selector R may be configured to input a determination command for checking the guide text.
As a result, the selector R may be configured to receive an input of a determination command for confirming or determining a corresponding control command according to a type of a control command displayed on the display 84.
The selector R may be configured to determine whether the control command displayed on the display P84 is selected by detecting whether a user's body is in contact with the window P85.
That is, the selector R may include a sensor R3 provided to the second circuit board 82 to sense static electricity of a user's body and a conductor R2 or a physical button R1 connecting the sensor R3 and the window P85.
The selector R may include a receiving portion R1 attached to or coupled to the window P85 and a transmitting portion R2 having one end connected to the receiving portion R1 and the other end connected to the sensor R3. In this case, a conductor through-hole 837 into which the transmitting portion R2 is inserted should be provided in the mounting body 831.
The receiving portion R1 is a means for facilitating an input of a control command by expanding an area in which a user can contact. In the control panel P having the above-described structure, the display area D1 is formed in the upper space of the window P85 and the input area D3 is formed in the lower space of the window P85. Therefore, when the width of the receiving portion R1 is set to be wide, the width of the input area D3 is expanded, and thus a user may more easily input a control command. It is preferable that the width of the receiving portion R1 is ¼ to ½ or less of the width of the window P85.
The transmitting portion R2 and the receiving portion R1 may be formed of a conductor. Accordingly, when the user's body is in contact, a body current of the user may be charged or transferred to transfer the current to the sensor R3.
In addition, the transmitting portion R2 and the receiving portion R1 may be provided as physical buttons. Accordingly, when a body of the user presses the receiving portion R1, a pressure of the body may be transferred to the sensor R3.
The receiving portion R1 may be provided as a film printed or attached to a rear surface of the window P85, or may be formed of a carbon-based material.
Meanwhile, the display unit P may include an inducing portion 839 for inducing the user to press the selector R.
The inducing portion 839 may guide the user to a position of the selector R to induce the user to input the selector R.
The inducing portion 839 may include a lamp 821 corresponding to the position of the receiving portion R1 and the lamp through-hole 835. Specifically, the inducing portion 839 may include the lamp through-hole 835 disposed under the display P84 and the lamp 821 installed in the lamp through-hole 835.
The lamp through-hole 835 and the lamp 821 constituting the inducing portion 839 may be disposed at the center under the display 84 with respect to the mounting part 83.
Accordingly, when the lamp 821 emits light in the inducing portion 839, the selector R or an area adjacent to the selector R may become bright.
In addition, the lamp 821 of the inducing portion 839 may be provided as an LED element or the like to display a separate text r or phrase.
The control panel P having the above-described structure enables the display of the control command, the search of the displayed control command, and the selection of the displayed control command, and can minimize the space required for installation. Yet, the control panel P having the above-described structure needs a means for blocking water or foreign substances from being introduced into the display unit P8 and the manipulation unit P7 or a means for discharging the introduced water or foreign substances externally.
The control panel P having the above-described structure may display a preset control command on the display P84 whenever a user turns the handle P73 (e.g., whenever the encoder generates an electrical signal) (search and change of a control command).
When a desired control command is displayed on the display P84, the user may select the displayed control command through the selector R. The control command selected through the selector R may be initiated when the user inputs an execution command through the execution unit P47.
Meanwhile, although the handle P73 is coupled to the first circuit board P4 so as to be rotatable, since the housing P81 of the display unit is fixed to the first circuit board P4, it is necessary to constantly maintain a gap between the handle P73 and the housing P81. This is because the rotation of the handle P73 may be restricted when the gap between the handle P73 and the housing P81 is not maintained.
In a state display area D1 of the display unit P8, whether the door is locked, whether a communication module is activated, whether a course or option is operated, whether a guide phrase is generated, and the like may appear in the form of icons.
In addition, the number of display contents that may appear while rotating the manipulation unit P7 may be displayed in the state display area D1. For example, a plurality of points may be disposed in a manner of being spaced apart from each other, and one of a plurality of the points may emit light to provide the number of contents displayed in a content display area D2.
The contents of a course and option, an execution state of the course or option, and a guide phrase necessary for a user may be displayed in the content display area D2.
The content display area D2 may be provided larger than the state display area D1.
An input area D3 may emit light to request a user's input, and a guide phrase indicating what kind of content the user should input may be displayed in the input area D3.
A power unit P46 may be provided on the left side of the display unit P8, and an execution unit P47 may be provided on the right side of the display unit P8.
The manipulation unit P7 may be rotatably provided on an outer circumferential surface of the display unit P8 and may be provided to rotate the drum 2.
The random course may be a series of control methods for performing a washing cycle of washing laundry.
When the manipulation unit P7 is rotated, a name of the corresponding course and a simple option name may be displayed in the content display area D2 of the display unit P8 according to a configured order, and a description of the course or option may be displayed.
The option may be selected by the setting unit P2. The setting unit P2 may be configured to receive an input of a selection command for selecting one or more of random options. The random option may include setting an additional condition of the course.
For example, the random option may include a configured algorithm or control method for adjusting at least one of the number of iterations for performing the course, the strength on performing each cycle, RPM of a drum on performing each cycle, a temperature of water, an amount of water, and a duration time of each cycle.
The setting unit P2 may be provided as a touch display capable of selecting the random option or may include a plurality of lamps and a plurality of conductor switches capable of sensing a user's body.
For example, the setting unit P2 may include an option selector B for receiving an input of a setting command for setting a condition for the course and an option display unit B4 for displaying option information corresponding to the option selector B.
For example, the option selector B may include a rinsing unit B1 for adjusting an RPM and duration time of the drum, an amount of water, and a rinsing power related to the number of rinsing times on performing a rinsing cycle in the course, a dewatering unit B2 for adjusting a dewatering force related to an RPM and duration time of a drum on performing a dewatering cycle in the course, and a temperature unit B3 for adjusting the temperature of the water on performing a washing cycle in the course.
The option display unit B4 may be configured to display the rinsing power, the dewatering force, and the temperature by objectifying and unitizing them.
Meanwhile, the setting unit P2 may be provided with a utilization unit C for receiving an input of a utilization command for utilizing the function of the laundry treating apparatus.
For example, the utilization unit C may include a washing unit C1 capable of inputting a special washing cycle for functional laundry, soft laundry, and tub cleaning, and the like, a reservation unit C2 for inputting a reservation command for performing a washing course at a specific time, a sterilization unit C capable of adding steam to laundry during the course cycle to promote sterilization, and an additional function unit C4 for utilizing additional functions such as pairing with other devices, etc.
In addition, the setting unit P2 may include a switching unit E for receiving an input of a connection command for communicating with the drying device 20 or the mini device 60.
Meanwhile, the setting unit P2 may turn on a light of a function that can be utilized at the present time or a function selected by a user, or turn off a light of a function that cannot be executed or a function that is not selected by the user.
The setting unit P2 may display all of the contents through an auxiliary display P19.
Hereinafter, an embodiment and control method of displaying and controlling the drying device 20 or the mini device 60 with the control panel P of the washing device 10 will be described. Yet, this is only to remove the repetitive description, and may be equally applied when the washing device 10 or the mini device 60 is controlled with the drying control panel PA.
In addition, the above embodiment and control method are equally applicable when the washing device 10 or the drying device 20 is controlled with the mini control panel PC.
The locking or unlocking of the control panel P described below may be applied to all of the washing device 10, the drying device 20, and the mini device 60.
The control panel P may perform a locking function that does not react to a user's command. In other words, the control panel P may perform a locking function in which a user's command input is deactivated.
The control panel P may omit an input unit capable of immediately performing a locking function. Accordingly, the control panel P may be locked only when a locking function intention of a user is reliably received.
To this end, when another separate input is performed on the control panel P, the control panel P may enter a step of setting a locking.
For example, referring to
Referring to
Only when a user selects and determines the approval information D21, the control panel P may be locked.
Referring to
The locking command may be approved by the input of the setting information D22.
The setting information D 22 may include receiving a user's selection by turning on/off a button locking.
As a result, in order for the user to perform a locking of the control panel P, the setting unit P2, the manipulation unit P7, and the selector R should be inputted. Therefore, the control panel P may be set to be locked only when there is a certain locking intention by inducing several configurations to be inputted instead of one configuration.
As a result, the control panel P may be prevented from being randomly locked.
Referring to
The locking information a may be displayed in a pop-up form on the display unit P8, and then removed after being displayed for a predetermined time only. Accordingly, a user may recognize that the control panel P is set to be locked, and immediately obtain state information of the laundry treating apparatus.
Referring to
That is, the locking information a disappears from the display unit P, but the locked state D11 is continuously displayed for other users to recognize that the control panel P is in a locked state.
In other words, the display unit P8 may externally display a state that an input of at least one of the manipulation unit P7, the execution unit P47, the power unit P46, and the setting unit P2 has been deactivated by using the locked state D11.
In this case, the light of the deactivated input unit P8 may be turned off to inform the user that the input is deactivated.
For example, all portions of the setting unit P2 except for the additional function unit C4 may be turned off and may not be displayed to the user. The additional function unit C4 may be set to enable an input for unlocking of the control panel P.
In addition, the display unit P8 may display a state that the input of the manipulation unit P7 is deactivated as the input of the selector R is deactivated.
Referring to
When the control panel P is set to be locked, the manipulation unit P7 may be configured to be deactivated not to receive an input. In addition, the execution unit P47 may also be configured to be deactivated not to receive an input. In addition, an input to the setting unit P2 may be also deactivated.
Accordingly, when the locking of the control panel P is performed, a progress of a course or option of the laundry treating apparatus may not be disturbed. As a result, confusion between one user controlling the laundry treating apparatus using the external terminal 40 and another user manipulating the laundry treating apparatus may be prevented.
Confusion between one user having performed the locking setting and another user may be prevented.
Yet, an input to the power unit P46 may be available. Hence, the operation of the laundry treating apparatus may be allowed to be stopped in an emergency situation.
Meanwhile, the user attempt to operate the control panel P without knowing that the control panel P is set to be locked.
Referring to
When a user applies an input to the remaining area except the manipulation unit P7, the execution unit P47, and the additional function unit C4 in the auxiliary display P19 of the setting unit P2, the control panel P may determine that the user is not aware of the locked state.
The input may include at least two inputs.
When the input is performed, the display unit P8 may display a guide a1 for releasing the locking command to the user. The guide a1 may include a phrase indicating a method of releasing the locking command.
Accordingly, the user may recognize the method of releasing the locking command, and the control panel P may confirm the user's certain unlocking intention.
Referring to
Hence, when the manipulation unit P7, the execution unit P47, and a portion of the setting unit are repeatedly inputted while the guide is displayed, the control panel P may display link information or a QR code, on which an image or phrase capable of releasing the locking command is displayed, on the display unit P8.
Accordingly, the user may intuitively recognize that the control panel P is currently in an input-deactivated state and acquire information for unlocking by photographing the QR code through the external terminal 40.
Furthermore, the user certainly recognizes that the control panel P is in a locked state according to the appearance of the QR code itself, so that the user may directly release the locking by pressing the additional function unit C 4.
The control panel P may input an unlocking command in a manner similar to inputting a locking command.
In other words, the control panel P may be unlocked in the same manner as the locking is set.
Referring to
Hence, the manipulation unit P7, the setting part P2, and the execution unit P47 may be in a state in which inputting is deactivated.
Yet, the additional function unit C4 in the auxiliary display P19 may remain in an input-activated state.
Referring to
The display unit P may display additional function lists on the display P84. The additional function list may include approval information D21 capable of releasing the locking command.
Only when a user selects and determines the approval information D21, the control panel P may be unlocked.
Referring to
The release of the locking command may be approved by the input of the setting information D22.
The setting information D22 may include receiving a user's selection through ON/OFF of a button lock.
As a result, in order to release the locking of the control panel P, the setting unit P2, the manipulation unit P7, and the selector R should be inputted. Accordingly, the locking of the control panel P may be released only when there is a certain unlocking intention by inducing the user to input several configurations instead of a single configuration.
When the locking of the control panel P is released, the display unit P8 may display unlocking information a2, which indicates that unlocking of the control panel is approved or set, on the display P84. The unlocking information a2 may display a guide message indicating that the input of the control panel P is activated. The guide message may include an explanatory a phrase “button lock is released.”
Referring to
Furthermore, the input of the selector R may also be activated on the display unit P8 to display a state in which the input of the manipulation unit P7 is activated.
The laundry treating apparatus according to the present disclosure may perform a setting entry step S1 of inputting the additional function unit C4 to the control panel P.
In the setting entry step S1, a locking selecting step S2 of selecting a locking command through the manipulation unit P7 may be performed.
In this case, an input checking step S3 of checking whether the locking command is finally determined with an input of the selector R or the execution unit P47 may be performed.
A time sensing step S4 of checking whether there is an input of the selector R or the execution unit P47 for a final determination for a reference time. If the reference time expires, the locking setting may be cancelled.
Hence, the display unit P8 may not be blocked from displaying the state of the laundry treating apparatus.
Meanwhile, when the locking command is finally determined by the input of the selector R or the execution unit P47, an excluding step S5 of excluding the additional function unit C4 from deactivation may be performed, and a locking setting step S6 of deactivating the input of the input unit P9 of the control panel P may be performed.
In doing so, the power unit P46 may be excluded from locking.
On the other hand, the display unit P8 may perform a locking displaying step S7 of displaying a guide phrase or a locked state D11 indicating that the locking is set.
A locking setting step N1 of setting a locking of the control panel P may be performed.
When the locked control panel P is inputted, a guide display step N8 of displaying a guide for unlocking may be displayed on the display unit P8.
Nevertheless, when the control panel P is repeatedly inputted, the display unit P8 may perform a link guide step N10 of displaying a link or QR code having an image for unlocking.
On the other hand, it may be able to perform a setting entry step N3 of inputting the additional display unit C4 for enabling a state of receiving an input of a command for performing an unlocking in the setting unit P2 rather than the locking area.
When the additional display unit C4 is inputted, an input checking step N5 of checking whether a locking command releasing command is finally determined with an input of the selector R or the execution unit P47 may be performed.
A time sensing step N6 of checking whether there is an input of a final determination to the selector R or the execution unit P47 is performed. When a reference time expires, the unlocking setting may be cancelled. Accordingly, it is possible to prevent the locking of the control panel P from being released randomly.
Meanwhile, when the unlocking command is finally determined by the input of the selector R or the execution unit P47, an unlocking step N7 of re-activating the input of the input unit P9 of the control panel P may be performed.
The present disclosure may be modified in various forms, and thus the scope of the present disclosure is not limited thereto. Therefore, if the modified embodiment includes the elements of the claims of the present disclosure, it should be construed as pertaining to the scope of the present disclosure.
