[0037] Hereinafter, preferred embodiments of a laundry treating apparatus and a control method thereof will be described in detail with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the clothing processing device 100 may include a housing 1, and a storage portion, a circulation flow path and a heat exchange portion may be provided inside the housing. The storage portion is provided inside the housing and stores drying objects (hereinafter, clothing), and the circulation flow path removes moisture from the clothing in the storage portion.

[0039] The housing 1 may include: a front surface 11 located in front of the laundry processing device; a back surface 12 located behind the laundry processing device; and a base 13 forming a bottom surface of the laundry processing device.

[0040] A control panel may be provided on the front side 11. The control panel may include: a display unit 114 for displaying control instructions selectable by a user; and an input unit 113 for enabling a user to select a control instruction displayed on the display unit 114.

[0041] like Figure 2 As shown, a box inlet 111 for taking clothes in and out is provided on the front side 11 , and the box inlet 111 can be closed by a door 115 rotatably fixed to the front side 11 .

[0042] like Figure 3 As shown, the accommodating portion may be composed of a drum 17 rotatably disposed inside the box 1. The drum 17 may be composed of a cylindrical drum body 171 with the front and back sides respectively opened.

[0043] The housing 1 may include a front panel 14 rotatably supporting the front surface of the drum body 171 and a rear panel 15 rotatably supporting the rear surface of the drum body 171 , so as to rotatably support the drum body 171 .

[0044] The front panel 14 may include: a front panel body 141 fixed to the front side 11 or the housing 1 ; a drum inlet 142 penetrating the front panel body; and a drum exhaust hole 143 for exhausting the air inside the drum body 171 to the circulation path 2 .

[0045] The drum inlet 142 may be connected to the box inlet 111. Therefore, when the door 115 opens the box inlet 111, the user may put clothes into the drum body 171 or take clothes out of the drum body 171 through the box inlet 111 and the drum inlet 142.

[0046] In order to filter the air exhausted from the drum body 171 , a filter that is detachable from the front panel body 141 may be provided at the drum exhaust hole 143 .

[0047] The rear panel 15 may include: a rear panel body 151 fixed to the back side 12 or the box body 1 ; and a roller supply hole 152 penetrating the rear panel body 151 .

[0048] The drum body 171 can be rotated by a driving unit 18 disposed inside the housing 1. The driving unit 18 may include a drum motor 181 fixed to the base 13 and a belt 182 connecting a rotating shaft of the drum motor and a circumferential surface of the drum body 171.

[0049] In order to stir the clothes inside the drum body 171, a lifting member 172 may be further provided inside the drum body 171. The lifting member 172 may be composed of a board protruding from the circumferential surface of the drum body 171 toward the rotation center of the drum body.

[0050] The circulation flow path 2 may include: a first pipe 21 connected to the drum exhaust hole 143; a second pipe 22 connected to the drum supply hole 152; and a third pipe (connection pipe) 23 connecting the first pipe and the second pipe. The connection pipe 23 may be fixed to the base 13.

[0051] like Figure 4 As shown, the heat exchange unit 3 may include: a circulation fan 36 to move air along the circulation flow path 2; and heat pumps 31, 32, 33, 34, 35 to sequentially dehumidify and heat the air moving along the circulation flow path 2.

[0052] The circulation fan 36 may include: a fan impeller 361 located inside the circulation flow path 2; and a fan motor 362 located outside the circulation flow path 2 to rotate the fan impeller 361.

[0053] The heat pump may include: a refrigerant pipe 33, forming a flow path for refrigerant circulation; a compressor 34, causing the refrigerant to move along the refrigerant pipe 33; a first heat exchanger 31, fixed to the refrigerant pipe 33, transferring the heat of the air flowing into the connecting pipe 23 to the refrigerant; a second heat exchanger 32, fixed to the refrigerant pipe 33, transferring the heat of the refrigerant to the air passing through the first heat exchanger 31; and a regulating valve 35, adjusting the pressure of the refrigerant.

[0054] The connecting pipe 23 may include: a pipe body 231 fixed to the base 13; and a pipe cover 232 forming the top surface of the pipe body. Figure 5 As shown, the duct body 231 may include: a first mounting portion 233, the first heat exchanger 31 is mounted on the first mounting portion 233; a second mounting portion 234, the second heat exchanger 32 is mounted on the second mounting portion 234; and a third mounting portion (fan mounting portion) 235, the fan impeller 361 is rotatably accommodated in the third mounting portion 235.

[0055] The air flowing into the connection duct 23 is condensed while passing through the first heat exchanger 31 , is heated while passing through the second heat exchanger 32 , and moves toward the drum main body 171 through the second duct 22 and the drum supply hole 152 .

[0056] The circulation flow path 2 may be provided with a support portion 4 for supporting the bottom surface of the first heat exchanger 31. The support portion 4 divides the interior of the connecting pipe 23 into an installation space 233a where the first heat exchanger 31 is located and a drainage space 233b for guiding condensed water to the outside of the circulation flow path (see Figure 4 The drainage space 233b is located at the lower part of the installation space 233a, and a drainage flow path 5 is provided in the drainage space 233b.

[0057] like Figure 6 As shown, the support portion 4 may include: a support body 41 supporting the bottom surface of the first heat exchanger 31; an extension body 42 extending from the support body toward the second heat exchanger 32; and fastening parts 43 and 44 fixing the support body 41 and the extension body 42 to the connecting pipe 23.

[0058] As an example, Figure 6 It is shown that the fastening portion includes fastening protrusions 43 protruding from two side surfaces of the supporting body 41 and fastening grooves 44 provided on the connecting pipe 23 and accommodating the fastening protrusions 43 .

[0059] The support body 41 is provided with a support body through hole 411, and the extension body 42 is provided with an extension body through hole 421. Therefore, the inner space of the connecting pipe 23 (the space where the first installation portion is located) is divided into the installation space 233a and the drainage space 233b by the support body 41 and the extension body 42, but the condensed water in the installation space 233a can move to the drainage space 233b through the support body through hole 411 and the extension body through hole 421.

[0060] The support body through hole 411 may be located at the lower part of the first heat exchanger 31, and the extension body through hole 421 may be located between the first heat exchanger 31 and the second heat exchanger 32. This is to prevent the condensed water that fails to move to the drainage space 233b through the support body through hole 411 from moving to the second heat exchanger 32 along with the airflow inside the connecting pipe 23.

[0061] The base 13 may be provided with a water collecting portion 6 for storing condensed water generated when air passing through the first heat exchanger 31 is condensed.

[0062] like Figure 5 As shown, the water collecting part 6 may be located outside the circulation flow path 2. In this case, preferably, the water collecting part 6 may be connected to the drainage space 233b through a drainage port 51 penetrating the connecting pipe 23, and the drainage flow path 5 is provided on the bottom surface of the connecting pipe 23 to guide the condensed water to the drainage port 51.

[0063] In order to naturally drain the condensed water (allowing the condensed water to move from the drainage path to the water collecting part under the action of gravity), the bottom surface of the water collecting part 6 can be located at a position lower than the drainage port 51, and the drainage path 5 can be formed as an inclined surface inclined downward toward the drainage port 51.

[0064] like Figure 3 As shown, the condensed water stored in the water collecting part 6 can be discharged to the drainage box 8 through the drainage part 7. The drainage box 8 can be located at a higher position than the water collecting part 6.

[0065] The drainage box 8 may include: a drawer 81 , which is removably disposed on the box body 1 and provides a space for storing condensed water; and a drawer through hole 82 , which passes through the top surface of the drawer 81 .

[0066] The front face 11 may be provided with an outlet 112 for the drawer 81 to enter and exit, and the interior of the box body 1 may be provided with a water tank cover 16 for providing a space for accommodating the drawer 81 .

[0067] The condensed water discharged from the water collecting portion 6 through the drainage portion 7 may move toward the water tank cover 16 through the supply pipe 72 , and the condensed water discharged from the supply pipe 72 may move toward the inside of the drawer 81 through the drawer through hole 82 .

[0068] On the other hand, if too much condensed water is supplied to the drawer 81, the condensed water inside the drawer 81 may be discharged to the water tank cover 16 through the drawer through hole 82. Therefore, a recovery pipe 73 may be further provided in the drainage portion 7, and the recovery pipe 73 connects the bottom surface of the water tank cover 16 and the water collecting portion 6 to guide the condensed water discharged from the drawer 81 to the water collecting portion 6.

[0069] like Figure 5 As shown, the water collecting part 6 may include: a storage body 61, which is arranged on the base 13 and stores condensed water; and a cover 62, which closes the open top surface of the storage body. Since the drain port 51 is arranged on the circumferential surface of the storage body 61, the storage body 61 is connected to the inside of the circulation flow path 2 through the drain port 51.

[0070] The cover 62 is provided with a supply port 622 and a recovery port 623 . The supply port 622 is connected to the supply pipe 72 , and the recovery port 623 is connected to the recovery pipe 623 .

[0071] In addition, the cover 62 is provided with a cover through hole 621 for installing the drain pump 71 of the drain unit 7 and a chamber 63. The chamber 63 is fixed to the cover 62 and is located inside the storage body 61. As shown in the figure, the chamber 63 may include: a chamber body 631 formed in a cylindrical shape surrounding the cover through hole 621; and a supply body 632 connecting the internal space of the chamber body 631 with the supply port 622.

[0072] In this case, the drain pump 71 may include a drain motor 711 fixed to the cover 62 , and an impeller 713 fixed to a rotating shaft 712 of the drain motor and located inside the chamber body 631 .

[0073] A chamber inlet 633 is provided at the bottom surface of the chamber body 631, so when the impeller 713 rotates, the condensed water inside the storage body 61 flows into the chamber body 631 and then moves to the supply port 622 through the supply body 632. The condensed water moved to the supply port 622 moves to the drainage tank 8 through the supply pipe 72.

[0074] The recovery port 623 penetrates the cover 62 to communicate with the storage body 61 , so that the condensed water discharged from the drainage tank 8 can move to the storage body 61 through the recovery pipe 73 and the recovery port 623 .

[0075] The clothes processing device of the above structure needs to maintain a space between the chamber inlet 633 and the bottom surface of the storage body 61, so it is inevitable that condensed water remains inside the storage body 61. The phenomenon of condensed water remaining inside the storage body 61 may become a factor that makes the sanitation management of the storage body 61, the heat exchange part 3 and the drum 17 difficult.

[0076] In order to minimize the problem of residual condensed water in the water collecting portion 6 , a condensed water removing portion 9 may be further provided in the laundry treating apparatus 100 .

[0077] The condensed water removal unit 9 is fixed to the base 13 or the cover 62 and supplies heated air to the water collection unit 6 to evaporate the condensed water inside the water collection unit. Figure 5 1 and 2 are diagrams showing a state in which the condensed water removing unit 9 is fixed to the cover 62 and heated air is supplied to the communication hole 624 of the cover.

[0078] like Figure 7 As shown, the condensed water removal unit 9 may include: a hot air supply unit 91 for supplying heated air to the water collecting unit 6; and a valve 92 for controlling the opening and closing of the hot air supply unit.

[0079] like Figure 8 As shown, the hot air supply unit 91 may include: a supply flow path 911 to supply external air to the water collecting unit 6; a supply fan 916 to allow external air to flow into the supply flow path; and a heater 915 to heat the air flowing into the supply flow path 911.

[0080] The supply flow path 911 may include: a supply pipe 913 fixed to the communication hole 624; and a heating pipe 912 connected to the supply pipe 913, and the heater 915 is installed on the heating pipe 912. In this case, the supply pipe 913 extends toward the upper part of the cover 62 (extends along the Y axis), and the heating pipe 912 may extend from one end of the supply pipe 913 along the length direction of the drum 17 (extends along the Z axis).

[0081] If the heating duct 912 extends along the length direction of the drum, the length of the heating duct 912 can be set long. The purpose of setting the length of the heating duct 912 long is to allow the air flowing into the heating duct to fully exchange heat with the heater 915 (increasing the temperature of the air supplied to the supply duct).

[0082] The heating pipe 912 can guide the air inside the box 1 or the air outside the box 1 to the supply pipe 913. As an example, Figure 8 913 is a diagram showing a heating duct that guides the air inside the housing 1 to the supply duct 913. The supply fan 916 may be provided at an inlet of the heating duct 912.

[0083] If the supply flow path 911 is always kept open, when the heat exchange unit 3 is operated to dry the clothes stored in the drum 17, part of the air passing through the first heat exchanger 31 can be discharged through the water collecting unit 6 and the supply flow path 911. The valve 92 is a member for solving such a problem.

[0084] The valve 92 may be configured to open and close the communication hole 624 provided in the cover, or may be configured to open and close the supply flow path 911. For example, Figure 8 1 and 2 are diagrams showing a state in which the valve 92 opens and closes the exhaust port 914 of the supply pipe.

[0085] Figure 8The valve 92 may include: a valve body 921 having a shape capable of opening and closing the exhaust port 914 ; and a valve motor 922 for controlling a rotation angle of the valve body 921 .

[0086] If a drying step for drying clothes or a sterilization step for sterilizing the drum or the heat exchanger is performed, condensed water is stored in the storage body 61. When the impeller 713 rotates, the condensed water inside the storage body 61 is discharged to the drain tank 8 through the supply port 622. After the impeller 713 stops rotating, the condensed water remaining inside the storage body 61 can be removed by operating the heater 915 and the supply fan 916 in a state where the supply flow path 911 is open.

[0087] like Fig. 9 As shown, the condensed water removal unit 9 may also be provided with a connecting pipe 917, the connecting pipe 917 connects the circulation flow path 2 and the water collecting unit 6, and guides a part of the air passing through the second heat exchanger 32 to the water collecting unit 6. Different from what is shown in the figure, the condensed water removal unit 9 may also include only the connecting pipe 917 without including the hot air supply unit 91.

[0088] Furthermore, in order to shorten the time for removing the condensed water inside the water collecting part 6, an actuator 93 may be further provided inside the water collecting part 6. The actuator 93 may be composed of an impeller (water collecting part impeller) provided on the bottom surface of the storage body 61 and rotated by a motor (located outside the water collecting part) or an ultrasonic generator provided inside the storage body 61.

[0089] Fig.10 1 is a diagram showing an example of a control method of the laundry processing apparatus 100 , the control method including a sterilization step, a flow path opening step, and a condensed water removing step.

[0090] The sterilization step is a step of supplying high-temperature dry air (air having a temperature higher than normal temperature and a humidity lower than the humidity of a space where a laundry treatment device is installed) to the inside of the drum 17 by operating the compressor 34 and the circulation fan 36. In the sterilization step, the supply flow path 911 is preferably kept in a closed state, so during the execution of the sterilization step, the valve 92 is controlled to keep the supply flow path 911 in a closed state.

[0091] The flow path opening step is a step in which the valve 92 opens the supply flow path 911 . The flow path opening step may be started after a preset reference time has passed since the sterilization step was performed.

[0092] The condensed water removing step may be started when the supply flow path 911 is opened by the flow path opening step. The condensed water removing step is a step of supplying heated air to the inside of the water collecting part 6 by operating the supply fan 916 and the heater 915 .

[0093] The condensed water removal step may include: a first interval in which the heater 915 is continuously operated; and a second interval in which the heater 915 is repeatedly operated and interrupted. The condensed water removal step may be terminated together with the sterilization step.

[0094] If the sterilization step and the condensed water removal step are completed, the control method performs a residual water removal step. The residual water removal step is a step of removing the condensed water remaining in the water collecting part 6 by interrupting the operation of the compressor 34 and the supply fan 916 and operating the circulation fan 36 and the heater 915. In the residual water removal step, the heater 915 may be repeatedly operated and interrupted.

[0095] The above-mentioned residual water removal step is set to be performed for a preset time after the sterilization step is completed, so Fig.10 The control method can prevent or minimize the situation where condensed water remains in the water collecting part.

[0096] The structure and control method of the above-mentioned clothes processing device are an illustration of an example of the present application, and the scope of rights of the present application is not limited to the above-mentioned structure and control method.
