The drainage device 70 may be connected to the tub 20 through a tub connection pipe 72. The drainage device 70 may discharge water from the tub 20 to the outside of the housing 10 through a drain pipe 73.


The clothes care apparatus 1 may include a water level sensor 200 for detecting a water level of the tub 20. The water level sensor 200 may be located outside the tub 20. For example, the water level sensor 200 may be installed below the upper detergent supply device 50. The location of the water level sensor 200 is not limited thereto.


The water level sensor 200 may be connected to a connection hose 201 extending from a branch pipe 72a of the tub connection pipe 72. The water level sensor 200 may be installed at an end of the connection hose 201 connected to the tub connection pipe 72. A water level of the connection hose 201 may be the same as that of the tub 20.


As the water level in the tub 20 increases, the water level in the connection hose 201 increases. An increase in the water level in the connection hose 201 may increase a pressure in the connection hose 201. The water level sensor 200 may detect pressure changes in the connection hose 201 and may detect the water level in the tub 20 corresponding to the pressure in the connection hose 201. The water level sensor 200 may generate an electrical signal corresponding to the pressure in the connection hose 201. A frequency of the electrical signal generated by the water level sensor 200 may vary depending on pressure changes in the connection hose 201.


In another example, the water level sensor 200 may be installed inside the tub 20. As the water level in the tub 20 increases, a pressure applied to the water level sensor 200 may increase. The water level sensor 200 may detect the water level in the tub 20 corresponding to the pressure.

The compressor 91, the condenser 92, the evaporator 93, and the expansion valve, that constitute the heat pump, may be disposed in the drying case 81. For example, the drying device 80 may further include a cooling fan 91a for cooling the compressor 91. For example, the drying device 80 may be formed as a single module.


The compressor 91 may compress the refrigerant, and the compressed high-temperature and high-pressure refrigerant may move to the condenser 92. The condenser 92 may cool the refrigerant to heat the surrounding air. The heated air may flow into the drum 30 to dry laundry.


The refrigerant expanded through the expansion valve may absorb heat from the evaporator 93 and cool the surrounding air. That is, the evaporator 93 may remove moisture by cooling the high-temperature and humid air that has passed through the inside of the drum 30. The air from which moisture has been removed may pass through the condenser 92, and may be heated again while exchanging heat with the refrigerant in the condenser 92. That is, the condenser 92 may heat the air that has passed through the evaporator 93. The condenser 92 and the evaporator 93 may correspond to a heat exchanger. The condenser 92 may be referred to as a ‘first heat exchanger’. The evaporator 93 may be referred to as a ‘second heat exchanger’.


For example, the drying device 80 may further include a drying heater 99. The drying heater 99 may increase a drying efficiency of the drying device 80. The heat pump components of the drying device 80 may be replaced with the drying heater 99.


The drying heater 99 may heat the air introduced into the drying device 80. The drying heater 99 may be disposed in a heating flow path 86.

The filter 95 may be located on a flow path through which air flowing into the drying device 80 moves to the evaporator 93 and the condenser 92.


The heat exchangers 92 and 93 may be disposed on the heating flow path 86. The heat exchangers 92 and 93 may include the condenser 92 and the evaporator 93. Because the air flowing into the heating flow path 86 has already passed through the inside of the tub 20, the introduced air may be humid. The humid air may be cooled in the evaporator 93 disposed in the heating flow path 86 to remove moisture. The air from which moisture has been removed in the evaporator 93 may pass through the condenser 92 and may be heated again.


The drying device 80 may include a nozzle device 96 to clean the heat exchangers 92 and 93. The nozzle device 96 may be arranged in the heating flow path 86. The nozzle device 96 may receive water from the water supply device 40 and may spray water toward the heat exchangers 92 and 93. The water sprayed from the nozzle device 96 may clean one side of the heat exchangers 92 and 93.


Meanwhile, the clothes care apparatus 1 may include a drain line 97 to guide the water discharged from the drying device 80 to the tub 20. The drain line 97 may be provided as a flexible hose, plastic pipe, or metal pipe.

The nozzle device 96 may be located adjacent to an area where air of the evaporator 93 is introduced.


The drain line 97 may be connected to the drainage device 70. The drain line 97 may be connected to the drain pump 71. Water discharged from the drying device 80 may flow to the drainage device 70 along the drain line 97. Water flowing into the drainage device 70 through the drain line 97 may be guided to the tub 20. Condensate water flowing into the tub 20 may be discharged to the outside of the clothes care apparatus 1 by an operation of the drain pump 71.


The supply flow path 87 may supply the air, heated while passing through the condenser 92, back to the inside of the tub 20. The supply flow path 87 may communicate with the heating flow path 86 and extend downward to discharge the heated air toward an opening of the tub 20.


The fan 87a may be provided on the supply flow path 87 to allow air to flow into the tub 20. That is, the fan 87a may supply air to the laundry in the drum 30. For example, the fan 87a may include a sirocco fan.


The inlet flow path 85, the heating flow path 86, and the supply flow path 87 may cause air to circulate into the inside of the tub 20 and the drying device 80.


In the clothes care apparatus 1, air discharged from the tub 20 may sequentially pass through the inlet flow path 85, the heating flow path 86, and the supply flow path 87 of the drying device 80 located above the tub 20, and then may be supplied into the tub 20.


The air heated in the drying device 80 may flow into the drum 30. In order to secure an area where the heated air supplied into the drum 30 comes into contact with the laundry, a tub exhaust port 27 may be disposed at a position opposite to an air inlet 26 through which the air heated in the drying device 80 flows into the tub 20. In order to increase a distance and/or time for the heated air to flow inside the drum 30 to allow the heated air to come into more contact with the laundry, the tub exhaust port 27 may be disposed at a position opposite to the air inlet 26 through which the air heated in the drying device 80 flows into the tub 20. The supply flow path 87 for supplying the heated air into the drum 30 and the tub exhaust port 27 may be arranged to be spaced apart from each other. By increasing the area of contact between the heated air and the laundry, drying efficiency may be improved.

The air in the tub 20 may be discharged to a tub duct 28 through the tub exhaust port 27 formed at the rear of the tub 20. The air discharged from the tub duct 28 may flow along the exhaust flow path P and be supplied to the drying device 80.


The clothes care apparatus 1 according to various embodiments may include the tub duct 28 to form a portion of the exhaust flow path P. For example, the tub duct 28 may be formed integrally with the tub 20. For example, the tub 20 may include the tub duct 28. The tub duct 28 may surround the tub exhaust port 27.


The clothes care apparatus 1 according to various embodiments may include a duct cover 29 to form a portion of the exhaust flow path P. The duct cover 29 may cover an open rear side of the tub duct 28. For example, the tub 20 may include the duct cover 29. The duct cover 29 may form at least a portion of the exhaust flow path P through which the air discharged through the tub exhaust port 27 flows to the drying device 80.


In the clothes care apparatus 1 according to various embodiments, the exhaust flow path P may be formed by coupling the duct cover 29 and the tub duct 28.


The tub duct 28 according to an embodiment may include a recess portion 28a that forms a portion of the exhaust flow path P through which the air discharged from the inside of the tub 20 flows. A reinforcing rib 23 may be arranged on a rear surface of the tub 20 to reinforce a rigidity of the tub 20. The recess portion 28a may be recessed from an end of the reinforcing rib 23 protruding from the rear surface of the tub 20. The recess portion 28a may be a portion of the rear surface of the tub 20 where the reinforcing rib 23 is not formed. The tub exhaust port 27 may be formed in the recess portion 28a to discharge air from the inside of the tub 20.

The duct connection portion 28b may protrude approximately upward from the outer circumferential surface of the tub 20. For example, the duct connection portion 28b may protrude upward from a rear end of the tub 20. However, the duct connection portion 28b is not limited thereto, and the duct connection portion 28b may be located at various positions depending on a location of the drying device 80.


The duct connection portion 28b may connect the tub duct 28 and the inlet guide 84 of the drying device 80. The duct connection portion 28b may extend the exhaust flow path P upward. The duct connection portion 28b may form a portion of the exhaust flow path P together with the recess portion 28a, the partition rib 28d, and the duct cover 29.


The duct connection portion 28b may be formed in a rectangular parallelepiped shape with an open top and rear surface. The duct cover 29 may cover an open rear side of the duct connection portion 28b. Only one side of the exhaust flow path may be formed by the duct cover 29, thereby facilitating coupling and sealing structure.


The duct cover 29 may cover the tub duct 28 and the duct connection portion 28b. The duct cover 29 may cover one open side of the tub duct 28 and the open rear side of the duct connection portion 28b. The duct cover 29 covers the recess portion 28a and the duct connection portion 28b, and thus the exhaust flow path P may be formed. Because the exhaust flow path P is connected to the inlet flow path 85, the air flowing into the exhaust flow path P through the tub exhaust port 27 may move along the exhaust flow path P, and may flow into the drying device 80 through the inlet flow path 85.


Although not illustrated, the duct connection portion 28b may be provided in a rectangular parallelepiped shape with only an upper surface open for air discharge and a rear surface closed. In this case, the duct cover 29 may cover only the tub duct 28.


Meanwhile, the duct connection portion 28b according to an embodiment of the disclosure may be included in the tub duct 28. The duct connection portion 28b of the tub duct 28 according to an embodiment may extend from the recess portion 28a to the inlet guide 84.

The water supplied to the tub 20 may pass through the lower detergent supply device 60. The detergent introduced into the lower detergent supply device 60 may flow into the tub 20 together with water. In a case where a water level in the tub 20 reaches a predetermined level, the controller 300 may close the first water supply valve 41 and the second water supply valve 42 to stop the supply of water to the tub 20. Thereafter, the controller 300 may rotate the drum 30 to agitate the laundry in the drum 30.


In a case where the detergent for the washing process 1501 is also introduced into the upper detergent supply device 50, the controller 300 may control the water supply device 40 to supply water to the upper detergent supply device 50 as well. Once water is supplied to the upper detergent supply device 50, the detergent introduced into the upper detergent supply device 50 may flow into the tub 20 together with the water.


To deliver the detergent to the tub 20, at least one of the upper detergent supply device 50 or the lower detergent supply device 60 may be used.


Once the washing process 1501 is completed, the rinsing process 1502 may be performed. The rinsing process 1502 may be performed one or more times. To perform the rinsing process 1502, the controller 300 may control the water supply device 40 to supply water to the tub 20.


In a case where the rinsing process 1502 is performed multiple times, in a first rinsing process, a softener introduced into at least one of the upper detergent supply device 50 or the lower detergent supply device 60 may flow into the tub 20 together with water. For example, the controller 300 may control the second water supply valve 42 to move the softener introduced into the upper detergent supply device 50 to the tub 20. Water may be supplied to the upper detergent supply device 50 through the second water supply valve 42 and the first pipe 441.


In a case where a water level in the tub 20 reaches a predetermined level, the controller 300 may control the water supply device 40 to stop the supply of water to the tub 20. That is, the controller 300 may close the first water supply valve 41 and the second water supply valve 42 to stop the supply of water to the tub 20. Thereafter, the controller 300 may rotate the drum 30 to agitate the laundry in the drum 30.


Once the rinsing process 1502 is completed, the spin-drying process 1503 may be performed. To perform the spin-drying process 1503, the controller 300 may operate the drain pump 71 to discharge water in the tub 20 to the outside of the clothes care apparatus 1. In addition, the controller 300 may rotate the drum 30 at a relatively high speed. By rotating the drum 30 rapidly, water may escape from the laundry due to centrifugal force.


Once the spin-drying process 1503 is completed, the drying process 1504 may be performed. To perform the drying process 1504, the controller 300 may operate the drying device 80 to supply hot air into the tub 20 and the drum 30. In addition, the controller 300 may rotate the drum 30 at a relatively low speed.


Immediately after entering the drying process 1504 or before the start of the drying process 1504, water may be supplied to the upper detergent supply device 50 for a predetermined period of time (e.g., 1 second) to prevent leakage of moisture in the tub 20. As described above, the detergent connection pipe 51 connecting the tub 20 and the upper detergent supply device 50 may be U-shaped, and a bent portion of the detergent connection pipe 51 may be filled with water by supplying water to the upper detergent supply device 50. The detergent connection pipe 51 blocked by (filled with) water may prevent the moisture in the tub 20 from being discharged to the outside through the upper detergent supply device 50.


Once the drying process 1504 is completed, the clothes care apparatus 1 may be stopped and be turned off.



FIG. 16 is a table illustrating a method for controlling a clothes care apparatus according to an embodiment of the disclosure.


Referring to a table 1600 of FIG. 16, based on an operation course selected by a user input to the clothes care apparatus 1, whether to perform at least one of a washing process, a rinsing process, a spin-drying process, or a drying process may be determined. To perform at least one of the washing process, the rinsing process, the spin-drying process, or the drying process, the controller 300 may control the water supply device 40 to supply water to at least one of the upper detergent supply device 50, the nozzle device 96, or the tub 20.


A first water supply flow path for supplying water to the upper detergent supply device 50 may refer to the first pipe 441. A second water supply flow path for supplying water to the nozzle device 96 may refer to the second pipe 442. A third water supply flow path for supplying water to the tub 20 may refer to the third pipe 443. As described above, the water supply device 40 may be connected to the first pipe 441, the second pipe 442, and the third pipe 443. The controller 300 may control the water supply device 40 to open or close each of the first pipe 441, the second pipe 442, and the third pipe 443.


For example, the second water supply valve 42 may include the first valve 42a for opening or closing the first water supply flow path, the second valve 42b for opening or closing the second water supply flow path, and the third valve 43c for opening or closing the third water supply flow path.


In another example, the second water supply valve 42 may be provided as a single valve having a flow path switching structure to guide water to at least one of the first water supply flow path, the second water supply flow path, or the third water supply flow path.


To perform the washing process, the controller 300 may control the water supply device 40 to supply water to the tub 20 and block the supply of water to the upper detergent supply device 50 and the nozzle device 96. For example, in the washing process, the controller 300 may close the first valve 42a to close the first water supply flow path connected to the upper detergent supply device 50, may close the second valve 42b to close the nozzle device 96 connected to the second water supply flow path, and may open the third valve 42c to open the third water supply flow path connected to the tub 20.


As the third water supply flow path is opened, water may be supplied to the tub 20. The water supplied to the tub 20 may pass through the lower detergent supply device 60, and the detergent contained in the lower detergent supply device 60 may be automatically introduced into the tub 20. As the detergent is introduced into the tub 20, the washing process may be performed. A user may select automatic detergent dispensing from the control panel 100. In response to a selection of automatic detergent dispensing, the detergent contained in the lower detergent supply device 60 may be automatically dispensed into the tub 20.


To perform the rinsing process, the controller 300 may control the water supply device 40 to supply water to the tub 20 and the upper detergent supply device 50 and block the supply of water to the nozzle device 96. For example, in the rinsing process, the controller 300 may open the first valve 42a to open the first water supply flow path connected to the upper detergent supply device 50, may close the second valve 42b to close the second water supply flow path connected to the nozzle device 96, and may open the third valve 42c to open the third water supply flow path connected to the tub 20.


The control of the opening of the first water supply flow path for supplying water to the upper detergent supply device 50 may be set for the rinsing process as a default. In addition, the opening of the first water supply flow path may be controlled according to user's settings.


For example, a user may select a manual setting for manually adding softener and/or bleach on the control panel 100. The user may add the softener and/or bleach to the upper detergent supply device 50. The controller 300 may operate the first valve 42a to move the water supplied to the upper detergent supply device 50 together with the softener and/or bleach added to the upper detergent supply device 50 to the tub 20 during the rinsing process.


In a case where a user selects an automatic setting for automatically adding softener and/or bleach on the control panel 100, the controller 300 may close the first valve 42a to close the first water supply flow path connected to the upper detergent supply device 50.


In the spin-drying process, water may be supplied to the tub 20 for a predetermined period of time to clean the door 17. In order to clean the door 17 based on the start of the spin-drying process, the controller 300 may control the water supply device 40 to supply water to the tub 20 and block the supply of water to the upper detergent supply device 50 and the nozzle device 96 for a predetermined door cleaning time (e.g., 3 seconds). For example, in order to clean the door 17 in the spin-drying process, the controller 300 may close the first valve 42a to close the first water supply flow path connected to the upper detergent supply device 50, may close the second valve 42a to close the second water supply flow path connected to the nozzle device 96, and may open the third valve 42c to open the third water supply flow path connected to the tub 20.


The water sprayed toward a front upper side of the tub 20 through the third pipe 443 may clean the door 17 located in front of the tub 20. The door cleaning may be performed early in the spin-drying process. After the door cleaning time has elapsed, all the water supply flow paths may be closed. The water supplied to the tub 20 for cleaning the door 17 may be discharged to the outside of the clothes care apparatus 1 as the spin-drying process proceeds.


In the drying process, water may be supplied to the upper detergent supply device 50 for a predetermined period of time to prevent moisture in the tub 20 from leaking to the outside. Based on entering the drying process, the controller 300 may control the water supply device 40 to supply water to the upper detergent supply device 50 and block the supply of water to the tub 20 and the nozzle device 96 for a predetermined period of time (e.g., 1 second) in order to prevent moisture leakage from the tub 20. For example, in the early drying process, the controller 300 may open the first valve 42a to open the first water supply flow path connected to the upper detergent supply device 50. Once water is supplied to the upper detergent supply device 50, a bent portion of the detergent connection pipe 51 connecting the tub 20 and the upper detergent supply device 50 may be blocked by (filled with) water, and the moisture in the tub 20 may be prevented from leaking to the outside through the upper detergent supply device 50.


While the drying device 80 is operating in the drying process, the controller 300 may close all of the water supply flow paths. In other words, while hot air is supplied to the tub 20 and the drum 30, water may not be supplied to the upper detergent supply device 50, the nozzle device 96, and the tub 20.


The clothes care apparatus 1 may clean the heat exchangers 92 and 93 included in the drying device 80 before completing the drying process. Water may be supplied to the nozzle device 96 for a predetermined period of time to clean the heat exchangers. The controller 300 may control the water supply device 40 to supply water to the nozzle device 96 for a predetermined heat exchanger cleaning time (e.g., 1 second) before completing the drying process and block the supply of water to the tub 20 and the upper detergent supply device 50. For example, the controller 300 may close the first valve 42a to close the first water supply flow path connected to the upper detergent supply device 50, may open the second valve 42b to open the second water supply flow path connected to the nozzle device 96, and may close the third valve 42c to close the third water supply flow path connected to the tub 20. By cleaning the heat exchangers 92 and 93, contamination (e.g. dust, lint) of the heat exchangers 92 and 93 may be removed, and the heat exchangers 92 and 93 may be kept clean.
