Description

Garment treatment device and method for controlling the garment treatment device

[0001] The present invention relates to a garment treatment device and a control method thereof. More specifically, the present invention relates to a garment treatment device and a control method thereof capable of performing refreshing processes, such as sterilizing, wrinkle removal, deodorizing, and drying, on garments by supplying steam and hot air to the garments.

[0002]

[0003] Recently, clothing treatment devices have emerged that can sterilize, deodorize, and dry clothing without washing with water or detergent, using hot air and steam to provide a refreshing experience. Examples of such conventional clothing treatment devices include Korean Patent Publication Nos. 10-2020-0057545 and 10-2011-0067832.

[0004] The above-mentioned clothing treatment device has the advantage of being able to manage clothing without water or detergent, so there is no damage to the clothing, and the time it takes to manage and wear the clothing again is faster than that of a washing machine or dryer.

[0005] In addition, since the above-mentioned clothing treatment device manages clothing while it is placed on the clothes without folding them, it has the advantage of being able to remove wrinkles without causing wrinkles in the clothes during the clothing treatment process.

[0006] These garment treatment devices are equipped to refresh garments by supplying steam to the garments and then supplying hot air to the garments to dry the garments.

[0007] However, if the supply of hot air is cut off after the clothes have dried, the temperature in the space where the clothes are placed can drop sharply, causing the relative humidity to increase. During this process, if moisture supplied by steam exists in the inner case and the clothes, this moisture can condense and remain on the surfaces of the clothes and inner case, potentially causing problems.

[0008] Therefore, the conventional clothing treatment device had a problem in that if the clothing was stored inside the clothing treatment device for a long period of time after the refreshing process was completed, the clothing would absorb moisture again, which had the adverse effect of causing the clothing to become wet again.

[0009] In addition, the conventional clothing treatment device had a problem in that if the clothes were not taken out after the refresh cycle was completed, there was a high possibility that bacteria would grow as air did not circulate inside the clothing treatment device as well as the clothes.

[0010]

[0011] The present invention aims to provide a clothing treatment device that can prevent the moisture content of clothing from increasing again even if the clothing is not taken out for a long period of time after the supply of steam and hot air to the clothing has been completed and the refreshing course has ended.

[0012] The present invention aims to provide a clothing treatment device capable of preventing internal humidity from increasing even after a course for refreshing clothing has ended.

[0013] The present invention aims to provide a clothing treatment device capable of maintaining the dry state of clothing even after the course for refreshing clothing has ended.

[0014] In order to solve the above-described problem, the present invention provides a clothing treatment device including a cabinet, an inner case provided inside the cabinet and having an opening at the front to provide a space for accommodating clothing, a circulation duct provided at a lower portion of the inner case and having a blower fan installed therein for circulating air inside the inner case, a machine room including an outside air duct for communicating the circulation duct with air outside the cabinet, a door rotatably provided on the cabinet to block at least one of the opening and the machine room, and a control unit for performing at least one of a drying course for drying the clothing by controlling the blower fan, a storage mode for circulating air inside the inner case to control humidity inside the inner case, and an outside air mode for receiving air outside the cabinet to control humidity inside the inner case.

[0015] The above storage mode and the above external mode can be set to be performed alternatively.

[0016] The above storage mode and the above external mode can be set to be performed when the above drying course is completed.

[0017] The above machine room may include a plurality of heat exchangers installed in the circulation duct to cool and heat the air, a compressor to heat refrigerant supplied to the heat exchangers, and an outside air damper to selectively open the outside air duct.

[0018] The above circulation duct may include an inlet duct that receives air inside the inner case or receives air outside the cabinet by communicating with the outside air duct, a moving duct that extends from the inlet duct and in which the heat exchanger is installed, an exhaust duct that extends from the moving duct and in which the blower fan is installed or in which the air is discharged to the inner case, and an inlet damper that selectively opens the inlet duct.

[0019] The above door may include a guide hole for receiving air from the inner case, a door chamber for connecting the guide hole with the outside of the cabinet, a lower communication portion spaced apart from the door chamber for connecting the outside air damper with the outside of the cabinet, and a door damper for selectively opening the guide hole.

[0020] The above storage mode and the above external mode can be controlled so that the inlet damper, the external damper, and the door damper open and close in opposite directions.

[0021] The above inlet damper, the outside air damper, and the door damper can open and close the inlet duct, the outside air duct, and the guide hole in opposite directions when the storage mode is performed and when the outside air mode is performed.

[0022] The above-mentioned external damper and the above-mentioned door damper can be controlled so that the external air duct and the above-mentioned guide hole are opened or closed together.

[0023] When the above storage mode is performed, the inlet damper can be controlled to open the inlet duct, the outside air damper can be controlled to close the outside air duct, and the door damper can be controlled to close the guide hole.

[0024] When the above storage mode is performed, the compressor and the blower fan can be operated.

[0025] At least one of the compressor and the blower fan can be operated intermittently or continuously during the storage mode.

[0026] The above door may further include an input unit for receiving a storage command for performing the above storage mode.

[0027] The above storage mode can be performed only when the above storage command is entered.

[0028] When the above external mode is performed, the inlet damper can be controlled to close the inlet duct, the external damper can be controlled to close the external duct, and the door damper can be controlled to close the guide hole.

[0029] When the above external mode is performed, the above blower fan can be operated.

[0030] When the above external mode is performed, the compressor may be blocked from operating.

[0031] The above outdoor mode can be set to be automatically performed when the above drying course is completed.

[0032] The above door further includes an input unit for receiving a storage command for performing the above storage mode, and the outside mode can be automatically performed when the drying course is completed if there is no input of the above storage command.

[0033] The above outdoor mode can be automatically terminated after a certain period of time has elapsed after the above drying course is completed.

[0034] The present invention has the effect of preventing the moisture content of clothing from increasing again even if the clothing is not taken out for a long time after the supply of steam and hot air to the clothing is completed and the refreshing course of the clothing is completed.

[0035] The present invention has the effect of preventing internal humidity from increasing even after the course for refreshing clothing has ended.

[0036] The present invention has the effect of maintaining the dry state of clothes even after the course for refreshing clothes has ended.

[0089] The heat supply unit (340) may be equipped with a heat pump system, or may be equipped with a heater that directly heats air using electric energy. If the heat supply unit (340) is equipped with a heat pump system, it may be equipped to dehumidify and heat the air discharged from the inner case (200) and supply it to the inner case (200). The detailed structure will be described later.

[0090] The above steam supply unit (800) may be provided to directly supply steam to the inside of the inner case (200).

[0091] The above steam supply unit (800) can generate steam by receiving water from the water supply tank (301) and heating the water by driving a heater. The heated steam can be supplied to a steam nozzle (900) positioned above the steam supply unit (800) and below the bottom surface of the inner case (200).

[0092] The above steam nozzle (900) is provided to communicate with the steam hole (233) and can supply the steam to the steam hole (233).

[0093] The water that is condensed and cannot be discharged from the steam nozzle (900) to the steam hole (233) can be recovered back to the steam supply unit (800).

[0094] The above base part (310) may be provided as a plate on which various devices are installed.

For example, the base bottom part (311) may extend from the circulation duct (320) to the corners of both sides of the machine room (300), and the iron module (S) may be mounted on the upper part of the base bottom part (311).

[0137] In addition, the iron module (S) may be installed in the machine room (300) by being placed outside the base floor portion (311). That is, the base floor portion (311) may have a smaller area than the floor surface of the machine room (300), and the iron module (S) may form the remaining floor surface of the machine room (300).

[0138] Figure 5 illustrates the inside of the circulation duct of the clothing treatment device of the present invention.

[0139] The above circulation duct (320) can extend upward from the base floor to form a flow path through which air flows.

[0140] The heat supply unit (340) may include an evaporator (341) that cools and condenses air moving along the circulation duct (320), a compressor (343) that receives refrigerant from the evaporator (341) and compresses and heats it, and a condenser (342) that receives refrigerant from the compressor (343) and heats the air moving along the circulation duct (320).

[0141] The above heat supply unit (340) may further include an expansion valve that expands the refrigerant that has passed through the condenser (342) to lower the temperature of the refrigerant.

[0142] The heat supply unit (340) may include an evaporator (341) installed inside the circulation duct (320) and equipped with a heat exchanger that cools and dehumidifies air introduced into the circulation duct (320), a condenser (342) equipped with a heat exchanger that heats air that has passed through the evaporator (341) to form hot air, a compressor (343) that supplies refrigerant that exchanges heat with the air to the condenser (342) and is arranged outside the circulation duct (320), and an expansion valve (344) that expands and cools the refrigerant that has passed through the condenser (342).

[0143] The above evaporator (341) and condenser (342) are placed inside the circulation duct (320), and the compressor (343) can be placed outside the circulation duct (320).

[0144] The above circulation duct (320) may include a heat exchanger installation part (3212) that provides a space in which an evaporator (341) and a condenser (342) are installed. The heat exchanger installation part (3212) may be provided inside the duct body (321).

[0145] The above duct body (321) may be provided with an open upper surface. A condenser (342) and an evaporator (341) may be installed by inserting them through the opening of the duct body (321).

[0146] The opening of the above duct body (321) can be shielded by the base cover (360), and the base cover (360) and the duct body (321) can form a path through which air moves inside the circulation path (320).

[0147] The front surface of the above duct body (321) can be arranged to be spaced rearward from the front end of the base bottom portion (311). As a result, the base bottom portion (311) can secure a support surface (3111) on which at least one of the above-described water supply tank (301) or drain tank (302) and the outdoor air duct (370) is installed and supported.

[0148] Meanwhile, as the duct body (321) is integrally formed with the base portion (310), the height of the heat exchanger installation portion (3212) can be secured longer, and the heights of the condenser (342) and the evaporator (341) can also be increased accordingly.

[0149] As a result, the width of the condenser (342) and the evaporator (341) in the front-rear direction can be reduced, thereby reducing the number of refrigerant pipes passing through the condenser and the evaporator. In addition, the effect of reducing the flow loss of air passing through the condenser and the evaporator is achieved.

[0150] Meanwhile, the sum of the length of the evaporator (341) and the length of the condenser (342) may be provided to be smaller than the length of the heat exchanger installation part (3212). Accordingly, the front-rear length of the heat exchanger installation part (3212) may be provided to be equal to or smaller than half of the length of the duct body (321).

[0151] The above blower (350) may be arranged to overlap the condenser (342) or the evaporator (341) in the front-rear direction. Accordingly, the air that has passed through the evaporator (341) and the condenser (342) can be introduced into the blower (350) without bending the flow path. That is, the air introduced into the circulation duct (320) can minimize flow loss because the flow path is not bent during the process of moving to the blower (350).

[0152] The length of the above ironing module (S) may be provided to be longer than the length of the above circulation duct (320).

[0153] Figure 6 illustrates a water supply and drainage system of the clothing treatment device of the present invention.

[0154] The clothing treatment device of the present invention may include a water supply tank (301) that supplies water to the steam supply unit (900) and a drain tank (302) that collects water condensed in the circulation duct (320) or ironing module (S).

[0155] The above water supply tank (301) and the above drain tank (302) should be selectively separated from the machine room (300) so that a user can easily fill the water supply tank (301) with water and discard the water collected in the drain tank (302).

[0156] The above machine room (300) may further include a detachable part (380) that is positioned in front of the refresh module (T) and supports the water supply tank (301) and the drain tank (302). The detachable part (380) may be detachably coupled to the water supply tank (301) and the drain tank (302).

[0157] The above detachable part (380) is provided in a plate shape to prevent the inside of the machine room (300) from being exposed.

[0158] A drainage pump (330) or the like may be provided at the lower portion of the detachable portion (380), and a circulation duct (320) may be provided at the rear of the detachable portion (380).

[0159] The above ironing module (S) may be provided so that a part thereof penetrates the detachable portion (380).

[0160] The above ironing module (S) may be placed on one side of either the water supply tank (301) or the drain tank (302). The ironing module (S) may not be placed between the water supply tank (301) and the drain tank (302). As a result, the front-rear length of the ironing module (S) can be sufficiently secured.

[0161] The above ironing module (S) can be arranged closer to the water supply tank (301) than to the drain tank (302). As a result, water can be easily supplied from the water supply tank (301), heated, and delivered to the steam iron (1300), and the structure for supplying water from the water supply tank (301) can be simply designed, and the volume occupied by the structure can also be minimized.

[0162] Figure 7 illustrates the structure of the base cover of the garment treatment device of the present invention.

[0163] The above base cover (360) may be provided to be coupled to the upper surface of the circulation duct (320) to prevent the interior of the circulation duct (320) from being exposed.

[0165] The above inlet body (361) may be provided in a duct shape to communicate between the inlet hole (231) of the inner case and the inside of the circulation duct (320). The inlet body (361) may be provided to protrude further upward than the shielding body (363).

[0166] The above inlet body (361) may be placed in front of the evaporator (341) so as not to face the evaporator (341) and the condenser (343).

[0167] The above inlet body (361) can serve as an inlet duct that moves air from the inner case (200) to the circulation duct (320).

[0168] The above inlet body (361) may be provided with an inlet port (362) through which air of the inner case (200) can pass.

[0169] Specifically, the base cover (360) may include a first rib (362a) extending along the width direction of the inlet body (361), and a second rib (362b) extending along the width direction of the inlet body (361) and spaced rearward from the first rib (362a).

[0170] The first rib (362a) and the second rib (362b) may be provided in parallel. The first rib (362a) and the second rib (362b) may be provided in a plate shape extending in a vertical direction, and the height may be provided to correspond to the height of the inlet body (361).

[0171] The front edge of the inlet body (361) and the first rib (362a) can form a first inlet port (3621) communicating with the first inlet hole (2311), the first rib (362a) and the second rib (362b) can form the central inlet port (3623) communicating with the second inlet hole (2312), and the rear edge of the second rib (362b) and the inlet body (361) can form a second inlet port (3623) communicating with the second inlet hole (2312).

[0172] The first inlet (3621) and the second inlet (3622) may be provided with the same area, and the central inlet (3623) may be provided with a smaller area than the first inlet (3621) and the second inlet (3622).

[0173] The above base cover (360) may include an inlet damper (364) provided to open and close the inlet portion (362), and a damper driving unit (365) coupled to the inlet damper (364) to control the opening and closing of the inlet damper (364).

[0174] The above inlet damper (364) may include a first damper part (3641) provided to open and close the first inlet port (3621), and a second damper part (3642) provided to open and close the second inlet port (3622).

[0175] The above first damper part (3641) is provided in a plate shape with an area corresponding to the first inlet (3621), and can be rotatably coupled to both sides of the inlet body (361) inside the first inlet (3621).

[0176] The second damper part (3642) is provided in a plate shape with an area corresponding to the second inlet (3622), and can be rotatably coupled to both sides of the inlet body (361) inside the second inlet (3622).

[0177] The central inlet (3623) above may be equipped with a blocking filter (366) that allows air to pass through but filters out foreign substances such as fine dust and lint.

[0178] The above blocking filter (366) may be provided so as to be inserted into the central inlet (3623) to partition the first inlet (3621) and the second inlet (3622). The blocking filter (366) may be arranged to extend from the central inlet (3623) to contact the bottom surface of the circulation duct (320).

[0179] The above blocking filter (366) may be provided as a filter capable of filtering moisture. For example, the above blocking filter (366) may be provided as a HEPA filter, etc.

[0180] Meanwhile, when the blocking filter (366) is inserted into the central inlet (3623), a shielding member that shields the central inlet (3623) can be further combined.

[0181] The above damper driving unit (365) may include a motor that provides power to selectively rotate the first inflow damper (3641) and the second inflow damper (3642), and a plurality of gear members that rotate while being engaged with the motor to selectively rotate the first inflow damper (3641) and the second inflow damper (3642).

[0182] The first inlet (3611) and the second inlet (3622) can be selectively opened due to the above damper driving unit (365).

[0183] Due to the above damper driving part (365), the air contained inside the inner case (200) may be introduced into the circulation duct (320) along the first inlet (3621) or may be introduced into the circulation duct (320) along the second inlet (3622).

[0184] Of course, the damper driving unit (365) may control the first inlet damper (3641) and the second inlet damper (3642) to open both the first inlet (3611) and the second inlet (3622), or may control the first inlet damper (3641) and the second inlet damper (3642) to block both the first inlet (3611) and the second inlet (3622).

[0185] The above damper driving unit (365) may be provided with any structure as long as it can rotate the first inflow damper (3641) and the second inflow damper (3642).

[0186] For example, the damper driving unit (365) may be provided as a combination of a motor, a driving gear that rotates by the motor, and a driven gear that is coupled to the first inflow damper and the second inflow damper and rotates by the rotation of the driving gear.

[0187] The above base cover (360) may include a shielding body (363) that extends from the inlet body (361) and can shield the evaporator (341) and the condenser (342). The shielding body (363) may be provided in a plate shape.

[0188] The above base cover (360) can be detachably connected to the upper surface of the circulation duct (320) through an inlet hook (3612) extending from the lower surface of the inlet body (361).

[0189] The above circulation duct (320) may be provided with a connecting portion that is detachably connected to the above inlet hook (3612).

[0190] Figure 8 illustrates the structure of an external air duct.

[0191] Referring to Fig. 8(a), the external air duct (370) can be coupled to the base portion (310).

[0192] The above-mentioned external air duct (370) may be provided to communicate with the above-mentioned external air intake unit (322).

[0193] The above-mentioned external air duct (370) may include an external air damper (373) that opens and closes the external air intake section (322) and an external drive section (374) that rotates the external air damper (373) to selectively open the external air intake section (322).

[0194] The above-mentioned external damper (373) may be provided in a plate shape capable of sealing the external air intake portion (322), and may be rotatably coupled to both sides of the external air intake portion (322).

[0195] The above external driving unit (374) may be provided as an actuator that is coupled to the external air duct (370) or circulation duct (320) and rotates the external air damper (373).

[0196] The above-mentioned external air duct (370) may further include an extension duct (372) extending forward from the external air intake portion (322) in front of the external air intake portion (322), and an intake duct (371) extending forward from the extension duct (372) to allow external air to be introduced.

[0197] The above intake duct (371) may be provided by extending from the lower portion of the extension duct (372), and a water supply tank (301) and a drain tank (302) may be arranged at the upper portion. The water supply tank (30) and the drain tank (302) may be coupled to or installed in the intake duct (371).

[0198] The above-mentioned intake duct (371) may include an external port (3711) through which external air is sucked at one end or a free end, and a partition rib (3712) provided to partition the external port (3711).

[0199] The above external device (3711) may be provided to communicate with the external hole (304).

[0200] The above partition rib (3712) is provided to partition the inside of the external device (3711) and can prevent foreign substances or the user's body from entering the inside of the external air duct (370).

[0201] Referring to Fig. 8(b), when the external driving unit (374) rotates the external damper (373) to open the external air intake unit (322), the intake duct (371) and the circulation duct (320) can be connected.

[0202] At this time, when the blower fan (352) is driven, the air outside the cabinet can be introduced into the circulation duct (320). When the compressor (342) is driven, the introduced outside air can be dehumidified while passing through the circulation duct (320) and supplied into the inner case (200).

[0203]

[0204] The above external air is filtered while passing through the blocking filter (366), and then flows into the guide hole (481) of the door through the inner case (200) and can be discharged to the outside of the cabinet (100).

[0205] Figure 9 illustrates the rear structure of the door of the garment treatment device of the present invention.

[0206] The above door (400) may include, in order from the front, a main panel (440), an auxiliary panel (450), a door body (410), and a door sealer (430).

[0207] The above door body (410) forms the main body of the door and is coupled to the cabinet (100) to open and close the opening (210).

[0208] The above door body (410) can have the main panel (440) and auxiliary panel (450) combined at the front, and the combination panel (420) can be combined at the rear.

[0209] The above door body (410) may be made of resin and may be provided with a certain thickness or more to ensure the rigidity of the door (400).

[0210] An exposed portion (482) may be provided on the upper part of the door body (410) so that air or moisture can be discharged to the outside.

[0211] The door body (410) may have lattice-shaped ribs arranged along the height direction. That is, the door body (410) may be provided in a combination of ribs that can reinforce or maintain rigidity, and may be provided with a penetration pattern over most of the area. This allows the weight of the door (400) to be reduced.

[0212] The above main panel (440) is provided in the shape of a plate made of glass or metal and can be combined with the front of the door body (410).

[0213] The above main panel (440) can also serve to protect the door body (410) and can be provided to serve as a mirror.

[0214] The above auxiliary panel (450) may be provided to shield a control panel that is coupled to the door body (410) to display the status of the control unit or to receive commands from a user.

[0215] The above auxiliary panel (450) may be made of a different material or color than the main panel (440).

[0216] Additionally, the auxiliary panel (450) may be made of a translucent material (e.g., glass, acrylic, etc.) through which light emitted from the control panel can be transmitted.

[0217] The above-mentioned coupling body (420) may be coupled to the rear of the door body (410) to form a door chamber in which air can flow between the coupling body and the door body (410), and may be provided with a structure in which a door sealer (430) can be coupled to the rear.

[0218] The above-mentioned joining body (420) is provided in the shape of a resin series plate and can form the back surface of the door (400) and can be exposed inside the inner case (200).

[0219] As a result, the main panel (440) and the joining panel (420) can perform the function of joining the front and rear of the door body (410) to shield the through hole formed in the front-back direction in the door body (410).

[0220] Accordingly, the door (400) can shield the inner case (200) and prevent the machine room (300) from being exposed to the outside. In addition, the weight of the door (400) itself can be reduced due to the above structure.

[0221] The door sealer (430) may be provided so as to correspond to the area and shape of the opening of the inner case (200). The door sealer (430) may be coupled to the back surface of the coupling body (420) and may be provided so as to be in contact with the entire perimeter of the opening of the inner case (200).

[0222] The above door sealer (430) may be provided to form a circumference of a closed curve or rectangle, and may be provided with an elastic material. Accordingly, when the door (400) closes the inner case (200), air and steam can be prevented from leaking between the door (400) and the inner case (200).

[0223] The above-mentioned joining body (420) may be provided with the guide hole (481) penetrating therethrough.

[0224] The above guide hole (481) can be placed inside the door sealer (430).

[0225] That is, the door sealer (430) may be placed outside the perimeter of the guide hole (481).

[0226] Accordingly, the internal air or moisture of the inner case (200) can flow into the guide hole (481) along the direction of the arrow and can be discharged through the exposed portion (482).

[0227] In this way, the inside of the inner case (200) and the outside of the cabinet (100) are directly connected, so that the humidity or temperature inside the inner case (200) can be controlled, and the inside of the inner case (200) can be prevented from rotting.

[0228] Figure 10 illustrates a structure in which the door connects the inside of the inner case and the outside of the cabinet.

[0229] The above door (400) may further include a door chamber (C) that can receive air or moisture inside the inner case (200) and guide it to the outside of the cabinet.

[0230] The above door chamber (C) can serve as a duct through which the air or moisture can move, and at the same time, provide a space in which a door damper (460) that opens and closes the guide hole (481) or the exposed portion (482) is installed.

[0231] The above door chamber (C) can be formed between the door body (410) and the joining panel (420).

[0232] The above door chamber (C) may be formed to protrude from the back surface of the door body (410) and may be formed to protrude from the front surface of the joining panel (420).

[0233] Alternatively, the door chamber (C) may be formed by combining the door body (410) and the joining panel (420).

[0234] For example, the above-mentioned joining panel (420) may be arranged closer to the top than the bottom on the back side, and a guide hole (481) may be formed in an area that can be arranged inside the door sealer (430), and a joining case (422) may be provided that protrudes along the perimeter of the guide hole (481) on the back side of the joining panel (420) and is provided to accommodate the guide hole (481).

[0235] The above-mentioned joining case (422) may be provided in a duct shape, with the surface facing the door body (410) being open, and the upper portion may be provided to be open based on the guide hole (481). The joining case (422) may be provided to shield both sides and the lower portion of the guide hole (481).

[0236] The above-mentioned joining case (422) may be provided to prevent air flowing into the guide hole (481) from leaking between the joining panel (420) and the main body (410) except for the exposed portion (482).

[0237] The above door body (410) may further include a body case (412) that protrudes from the rear surface to accommodate the coupling case (422) and be coupled to the coupling case (422) or be engaged with the coupling case (422).

[0238] The above body case (412) may be provided in a duct shape, but may be provided so that the surface facing the coupling body (420) is open, and the upper portion may be provided so as to be open based on the guide hole (481). The body case (412) may be provided so as to shield both sides and the lower portion of the guide hole (481).

[0239] The above body case (412) and the above combination case (422) may be combined with each other to provide a door chamber (C) having a certain volume.

[0240] The above door body (410) may further include an upper frame (413) provided above the door chamber (C) to form the upper end of the door (400).

[0241] The above door chamber (C) may be provided lower than the upper frame (413), and may be provided so that at least a portion thereof overlaps the upper frame (413) in the vertical direction.

[0242] The above exposure portion (482) may be provided to penetrate the upper frame (413) in the vertical direction to connect the door chamber (C) with the upper exterior of the door (400).

[0243] Accordingly, air flowing into the guide hole (481) can be received or guided into the door chamber (C) and discharged through the exposed portion (482).

[0244] The above door body (410) may further include a service panel (416) that is provided to penetrate an area corresponding to the front of the body case (412) and expose the guide hole (481) to the outside. The service panel (416) may be detachably provided on the door body (410).

[0245] The above service panel (416) can be coupled to the door body (410) to perform the function of sealing the door chamber (C), and can be detached from the door body (410) to expose the guide hole (481) and the door damper (460) described below to the front of the cabinet, thereby facilitating installation and maintenance of the door damper (460).

[0246] The above door damper (460) may be provided in a flap shape to shield the guide hole (481).

[0247] The above door damper (460) can be placed between the door body (410) and the joining panel (420).

[0248] The above door damper (460) may be accommodated inside the door chamber (C) and provided to selectively open the guide hole (481).

[0249] The above door body (410) may be arranged so that a straight plate (414) and a grid plate (415) form a pattern at the bottom of the door chamber (C) and extend downward.

[0250] Figure 11 illustrates a structural example of the above door damper.

[0251] The door damper (460) may include a door flap (461) having a shape corresponding to the guide hole (481) or an area larger than the guide hole (481) so as to be able to shield the entire guide hole (481), a door actuator (462) provided to rotate the door flap (461) and selectively open the guide hole (481), a damper hinge (464) forming a center of rotation of the door flap (461), and a damper support (463) provided to support the door actuator (462).

[0252] The above guide hole (481) may be provided in a rectangular shape with a width longer than a height, and the damper hinge (464) and the door actuator (462) may be provided to be arranged at the bottom of the door flap (461) so that the door flap (461) rotates up and down based on the bottom surface.

[0253] In this way, the guide hole (481) can be opened in such a way that the upper end of the door flap (461) moves closer to or further away from the guide hole (481).

[0254] Figure 12 illustrates a structure in which inner case air or moisture is discharged from the door.

[0255] The upper communication portion (480) may include the guide hole (481), the door chamber (C), and the exposed portion (482).

[0256] When the guide hole (481) is opened by the door damper (460), the air or moisture inside the inner case (200) can flow in the front and rear directions through the guide hole (481), then reach the door chamber (C) and be discharged upward through the exposed portion (482).

[0257] When moisture condenses as air or moisture is discharged, the moisture cannot pass through the exposed portion (482) and can be collected and evaporated in the door chamber (C). Therefore, excessive moisture can be prevented from being discharged all at once outside the garment treatment device.

[0258] The above-mentioned exposed portion (482) may include an upper frame (413) provided on the upper portion of the door body (410), an exposure hole (4821) penetrating the upper and lower direction of the upper frame (413) to expose the door chamber (C) to the outside, and a plurality of exposure ribs (4822) extending in the front-rear direction of the exposure hole (4821) but spaced apart in the width direction.

[0259] The above-mentioned exposed rib (4822) can reinforce the rigidity of the exposed portion (482) and prevent foreign substances from entering or being discharged, and can also guide the direction in which the air moves.

[0260] The above-mentioned exposed portion (482) may further include a coupling portion (4833) to which the main panel (440) can be coupled or fixed at least on one of the upper and front portions.

[0261] The above-mentioned connecting portion (4833) can be placed between the above-mentioned exposed ribs (4822).

[0262] Accordingly, when the door damper (461) opens the guide hole (481), the inner case (200) can communicate with the door chamber (C). Air containing moisture inside the inner case (200) can be discharged to the exposed portion (482) through the door chamber (C).

[0263] Hereinafter, various embodiments of the clothing treatment device of the present invention controlling the door damper, inlet damper, and external air damper will be described through FIGS. 13 to 16. The clothing treatment device of the present invention can perform any drying course (or drying course) for treating clothing by driving the refresh module (T).

[0264] The above drying course may be composed of a series of control methods that perform a refreshing process of removing wrinkles, deodorizing, and drying the clothing by supplying steam and heated air, which is hot air, to the clothing.

[0265] The garment treatment device of the present invention may be equipped to drive the moving hanger (500) to shake the garment when performing the above course.

[0266] Meanwhile, the clothing treatment device of the present invention may perform a communication course that connects at least one of the inside of the inner case (200) and the inside of the machine room (300) with the outside of the cabinet (100).

[0267] The above-mentioned ventilation course may include introducing external air of the cabinet (100) into the inner case (200) and the circulation duct (320), or discharging air from the inner case (200) and the circulation duct (320) to the outside of the cabinet (100).

[0268]

[0269] The above-mentioned chimney course can be used for the purpose of dehumidifying or purifying the air in the room where the clothing treatment device is placed.

[0270] Alternatively, the above-mentioned ventilation course may be used for the purpose of ventilating the inner case (200) and the inside of the machine room (300), lowering the humidity, or cooling the residual heat.

[0271] The above drying course corresponds to a course in which the clothing treatment device of the present invention processes clothing stored inside while minimizing environmental changes in temperature and humidity of the indoor space in which the clothing treatment device is installed, and the above ventilation course may correspond to a course in which the clothing treatment device of the present invention allows changes in the indoor space. The drying course may perform at least one of a hot air mode that supplies hot air to the inside of the inner case (200) and a steam mode that supplies steam to the inside of the inner case (200).

[0272] When the garment treatment device of the present invention performs the drying course, it can control the external air damper (373) and the door damper (460) to close the external air duct (370) and the guide hole (481), and the inlet damper (364) to open the inlet duct (361). Accordingly, the garment treatment device of the present invention can isolate the inner case (200) or the machine room (300) from the outside of the cabinet (100) when performing the drying course. Accordingly, it is possible to prevent the environment, such as the temperature and humidity of the indoor space, from changing during the drying course. In addition, when the clothing treatment device of the present invention performs the above-described communication course, it can be controlled to drive the outside air damper (373) and the door damper (460) to open at least one of the outside air duct (370) and the guide hole (481), and to drive the inlet damper (364) to close the inlet duct (361).

[0273] Accordingly, when the garment treatment device of the present invention performs the above-described communication course, the inner case (200) and the inside of the machine room (300) communicate with the outside of the cabinet (100), but the air inside the inner case (200) and the air inside the machine room (300) can be prevented from circulating with each other.

[0274] In this way, it is possible to prevent the temperature and humidity of the indoor space and other environmental conditions from being changed during the process of performing the above-mentioned communication course, and to prevent the internal conditions of the inner case (200) and the machine room (300) from being maintained.

[0275] Figures 13 and 14 illustrate examples of operation of the external damper (373), door damper (460), and inlet damper (364) when performing a drying course.

[0276] When performing the above drying course, the external air duct (370) and the guide hole (481) are commonly closed, and the inlet duct (361) can be performed in an open state.

[0277] Figure 13(a) illustrates the hot air mode being performed during the drying course, and Figure 13(b) illustrates the internal flow path of the machine room when the hot air mode is performed.

[0278] The above hot air mode may include the door damper (461) shielding the guide hole (481), the outside air damper (373) shielding the outside air intake (322), the first damper (3641) opening the first inlet (3621), and the second damper (3642) shielding the second inlet (3622).

[0279] The above hot air mode may include driving the blower fan (352).

[0280] When the above blower fan (352) is driven, a negative pressure is formed inside the machine room (300), so the air inside the inner case (200) can be filtered by flowing into the first inlet (3621) and passing through the filter (366).

[0281] The above hot air mode may include driving the compressor (342). When the compressor (342) is driven, air that has passed through the filter (366) by the blower fan (352) may be heated after being dehumidified while passing through the evaporator (341) and the condenser (343).

[0282] The air that has passed through the heat exchanger passes through the fan installation unit (350) and is supplied into the inner case (200) to be supplied to the clothing placed on the moving hanger. In this process, clothing containing moisture can be dried and sterilized.

[0283] The state in which the above hot air mode is performed may be a state in which steam is not supplied to the inner case (200) or after steam is supplied. This is in consideration of the fact that when steam is supplied to the inner case (200), the moisture may wet the filter (600), which may cause the performance of the filter (366) to be unguaranteed, or the filter (366) may be contaminated with bacteria or mold.

[0284] As a result, the hot air mode can be performed when steam is not supplied to the inner case (200), before steam is supplied inside the inner case (200), or when the absolute humidity is low even after steam is supplied inside the inner case (200). In the hot air mode, the air inside the inner case (200) can be introduced into the first inlet (3641) after being exposed to the clothing. As a result, foreign substances discharged from the clothing or remaining inside the inner case (200) can be filtered by passing through the filter (366). As a result, clean hot air can be supplied inside the inner case (200).

[0285] Figure 14(a) illustrates the steam mode being performed during the drying course, and Figure 14(b) illustrates the flow path of the machine room when the steam mode is performed.

[0286] The above steam mode may include the door damper (461) shielding the guide hole (481), the outside air damper (373) shielding the outside air intake (322), the first damper (3641) shielding the first inlet (3621), and the second damper (3642) opening the second inlet (3622).

[0287] The above steam mode may include driving the steam supply unit (800). That is, in the steam mode, steam may be generated and supplied to the inside of the inner case (200) from the steam supply unit (800).

[0288] The steam injected into the inner case (200) may rise due to the density difference and be exposed to clothing placed on the moving hanger (500). The steam (S) may heat the surface of the clothing, increase the moisture content of the clothing, and sterilize the clothing.

[0289] The above steam mode may include driving the blower fan (352). Air inside the inner case (200) may be introduced into the second inlet (3622). Since the second inlet (3622) is provided downstream of the blocking filter (366), air introduced into the second inlet (3622) may not pass through the blocking filter (366).

[0290] The above steam mode may include driving the compressor (342). In the above steam mode, the compressor (342) may be driven after driving the steam supply unit (800).

[0291] When the compressor (342) is operated in the steam mode, the air introduced into the second inlet (3622) can be dehumidified and heated while passing through the evaporator (341) and the condenser (343) without passing through the filter (366).

[0292] The air that has passed through the above heat exchanger can pass through the fan installation part (350) and be supplied into the inner case (200).

[0293] Accordingly, even if the humidity inside the inner case (200) is high, the moisture added by the steam can be condensed and removed in the evaporator (341). Accordingly, dry, high-temperature hot air can be supplied again to the inner case (200).

[0294] During this process, volatile substances and odor-causing substances on the clothing can evaporate along with the moisture contained in the clothing. Additionally, wrinkles on the clothing can also be removed.

[0295] As a result, when steam is supplied to the inner case (200) due to the steam mode, or when the steam mode is terminated and the humidity inside the inner case (200) is very high, the air of the inner case (200) is allowed to flow into the second inlet (3622) and is blocked from flowing into the first inlet (3621), thereby preventing the blocking filter (366) from being exposed to moisture.

[0296] Accordingly, the clothes placed on the moving hanger (500) can be refreshed, and the environment outside the cabinet (100) can remain unchanged.

[0297] Figures 15 and 16 illustrate examples in which a communication course is performed.

[0298] The above-mentioned communication course can perform at least one of an external air mode that connects the inner case (200) and the machine room (300) to the outside, and a dehumidification mode that controls the temperature and humidity of the environment in which the cabinet (100) is placed through the inner case (200) and the machine room (300).

[0299] The above external mode can be performed to remove moisture or humidity remaining inside the inner case (200) and the machine room (300) and to release high-temperature residual heat.

[0300] The above dehumidification mode can be performed to control the temperature and humidity of the external environment through at least one of the heat pump system and the steam supply unit (800) provided in the machine room (300).

[0301] Figure 15(a) illustrates a clothing treatment device in which the above-mentioned external mode is performed, and Figure 15(b) illustrates the flow path of the machine room when the above-mentioned external mode is performed.

[0302] The above external mode can perform at least one of the following: the door damper (461) opens the guide hole (481) and the external damper (373) opens the external air intake part (322).

[0303] That is, the external mode may include opening at least one of the guide hole (481) and the external air duct (370) to allow air to flow between the inner case (200) and the inside of the circulation duct (320) and the outside of the cabinet (100).

[0304] In addition, the external mode may further include the first damper (3641) shielding the first inlet (3621) and the second damper (3642) shielding the second inlet (3622). As a result, the air inside the inner case (200) and the air inside the circulation duct (320) can be prevented from circulating with each other.

[0305] The above external mode may include blocking the operation of the compressor (342).

[0306] Accordingly, the air outside the cabinet (100) can communicate with the inside of the inner case (200) and the inside of the circulation duct (320) without being separately dehumidified or heated.

[0307] The moisture inside the inner case (200) can be discharged to the outside of the cabinet (100) through the outside air duct (370) or the guide hole (481) due to diffusion, and the temperature inside the inner case (200) and the inside of the circulation duct (320) can be in equilibrium with the outside air exposed to the outside air duct (370) or the guide hole (481).

[0308] Meanwhile, the above external mode may include blocking the operation of the blower fan (352).

[0309] In this way, while using energy, it is possible to actively introduce outside air from the cabinet (100) into the machine room (300) or the inner case (200) through the outside air duct (370), or not to discharge the air inside the machine room (300) and the inner case (200) to the outside.

[0310] That is, the external air mode may correspond to maintaining a state in which the inside of the circulation duct (320) and the inside of the inner case (200) are connected to the outside of the cabinet (100) through the external air duct (370) and the guide hole (481). Accordingly, the external air mode can induce the conditions such as temperature and humidity inside the inner case (200) and the circulation duct (320) to be in equilibrium with the outside of the cabinet (100) without consuming separate energy. Accordingly, moisture condensed inside the circulation duct (320) or moisture remaining in the inner case (200) can evaporate to the outside of the cabinet (100), and residual heat inside the circulation duct (320) and the inner case (200) can be cooled.

[0311] As a result, the clothing is not damaged by residual heat, the clothing is prevented from rotting due to moisture, etc., and the growth of bacteria, etc., inside the circulation duct (320) and the inner case (200) can be prevented.

[0312] Meanwhile, the outdoor mode may include driving the blower fan (352).

[0313] When the above blower fan (352) is driven, the external air of the cabinet (100) is introduced into the circulation duct (320) through the outdoor air duct (370), passes through the blocking filter (366), and can be discharged through the guide hole (481) through the inside of the inner case (200).

[0314] However, the air inside the inner case (200) can be blocked from flowing into the machine room (300) through the inlet (362).

[0315] Accordingly, foreign substances such as fine dust contained in the outside air can be filtered by the blocking filter (366) and supplied to the inside of the circulation duct (320) and the inner case (200) and discharged through the guide hole (481). As a result, moisture inside the inner case (200) and the circulation duct (320) can be evaporated more quickly and residual heat can be cooled.

[0316] Of course, even if the blower fan (352) operates in the above-described outdoor mode, the operation of the compressor (342) can be blocked. Therefore, it is possible to prevent power consumption from increasing in the outdoor mode.

[0317] In addition, in the above external mode, the blower fan (352) may be operated intermittently. This induces the formation of a flow path in a certain direction inside the machine room (300) and inside the inner case (200), thereby preventing moisture or heat from accumulating.

[0318] Meanwhile, the above-described external mode can be set to end when the humidity inside the inner case (200) and the circulation duct (320) corresponds to the humidity outside the cabinet, or when the temperature inside corresponds to the temperature outside the cabinet, or when the mode is performed for a certain period of time.

[0319] Fig. 16(a) illustrates a clothing treatment device in which the dehumidification mode is performed, and Fig. 16(b) illustrates the flow path of the machine room when the dehumidification mode is performed.

[0320] The above dehumidification mode can be achieved by the door damper (461) opening the guide hole (481) and the outside air damper (373) opening the outside air intake portion (322).

[0321] That is, the dehumidification mode can actively introduce air from outside the cabinet (100) into the circulation duct (320) and the inner case (200) by opening both the guide hole (481) and the external air duct (370), and can actively discharge air from inside the circulation duct (320) and the inner case (200) to the outside of the cabinet (100).

[0322] In addition, the dehumidification mode may further include the first damper (3641) shielding the first inlet (3621) and the second damper (3642) shielding the second inlet (3622). As a result, the air inside the inner case (200) and the air inside the circulation duct (320) can be prevented from circulating with each other.

[0323] Additionally, the dehumidification mode may include driving the blower fan (352).

[0324] In this way, the dehumidification mode can draw in outside air through the outside air duct (370), pass it through the machine room (300) and the inner case (200), and then discharge it back to the outside of the cabinet (100). In this process, the inside of the inner case (200) and the machine room (300) can be dehumidified.

[0325] Meanwhile, the dehumidification mode may include driving the compressor (342).

[0326] The above dehumidification mode can remove moisture from air drawn in from outside the cabinet (100) by driving the compressor (342) and heat it. As a result, the humidity of the air outside the cabinet (100) can be lowered, thereby dehumidifying the indoor space. In addition, by drying the air outside the cabinet (100) at a high temperature and then passing it through the circulation duct (320) and the inner case (200), the circulation duct (320) and the inside of the inner case (200) can also be dehumidified.

[0327] When the compressor (342) is driven, the outside air that has passed through the filter (366) can be dehumidified while passing through the evaporator (341) and the condenser (343).

[0328] The air that has passed through the above heat exchanger passes through the fan installation part (350) and is supplied into the inner case (200), so that purified hot air can be supplied to the placed clothing.

[0329]

[0330] That is, the outside air introduced into the outdoor air duct (370) can be filtered by passing through the filter (366). As a result, the indoor space can be not only dehumidified but also the air can be purified.

[0331] As a result, unlike the outdoor mode, the dehumidification mode can simultaneously dehumidify not only the outside of the cabinet but also the inside of the inner case (200) and the circulation duct (320) by using energy by driving at least one of the compressor (342) and the blower fan (352).

[0332] In addition, since the guide hole (481) is opened in both the external mode and the dehumidification mode, the door (120) can circulate air outside the cabinet (100) and inside the inner case (200) and the machine room (300) without opening the inner case (200) and the machine room (300). Consequently, the garment treatment device of the present invention can determine the flow direction or circulation direction of the air inside the inner case (200) and the air outside the cabinet by controlling the external driving unit (374), the damper driving unit (365), the door driving unit (462), and the blower fan (352) by the control unit (700).

[0333] When the clothing treatment device of the present invention performs the drying course, it can refresh the clothing by supplying at least one of hot air and steam to the clothing.

[0334] Even if steam is supplied to the above clothing and the moisture content of the above clothing increases, hot air is ultimately supplied to the above clothing so that the above clothing can be dried. Drying course Drying course

[0335] At the time the above drying course is completed, the inside of the inner case (200) and the inside of the circulation duct (320) may be at a higher temperature than the outside of the cabinet (100) due to the supplied hot air, and may be in a dry state with low relative humidity.

[0336] However, as the temperature inside the inner case (200) gradually decreases, the relative humidity inside the inner case (200) may gradually increase.

[0337] In addition, as the temperature inside the circulation duct (320) drops, moisture may condense, and a certain amount of moisture remaining inside the circulation duct (320) may evaporate and flow into the inner case (200) through the exhaust duct or the inlet duct.

[0338] In this situation, if the clothing is left for a long time, the moisture content of the clothing placed in the inner case (200) may increase again even after the drying cycle has been performed. In this state, if the inside of the inner case (200) and the circulation duct (320) are not ventilated with the outside of the cabinet (100), bacteria may breed inside the inner case (200) and the circulation duct (320), and the clothing placed in the inner case (200) may become re-contaminated, or even if not contaminated, it may cause the user to misunderstand that the clothing has not been properly handled.

[0339]

[0340] To prevent this, the clothing treatment device of the present invention may be configured to perform at least one of the drying course and the ventilation course additionally after the drying course is completed, thereby maintaining a dehumidification state of at least one of the inner case (200), the circulation duct (320), and the clothing.

[0341] For example, the control unit of the clothing treatment device of the present invention can be controlled to selectively perform either the hot air mode of the drying course or the outside air mode of the ventilation course when the drying course is finished.

[0342] The above-mentioned outside mode can lower the humidity and temperature of the inner case (200) and the circulation duct (320) by connecting the machine room (300) and the inner case (200) with the outside of the cabinet (100), and the above-mentioned hot air mode can lower the humidity and temperature of the inner case (200) and the circulation duct (320) by increasing the temperature inside the machine room (300) and the inner case (200) and circulating the air.

[0343] The above control unit may be set to automatically perform at least one of the hot air mode and the outdoor air mode when the drying course is completed.

[0344] In addition, the control unit may receive a command from a user through the input unit and perform at least one of the hot air mode and the outdoor air mode when the drying course is completed.

[0345] For example, the control unit may be configured to automatically perform the outdoor mode when the drying course is completed. For example, the outdoor mode may be performed until the door is opened after the drying course is completed.

[0346] When the above door is opened, it can be expected that clothing will be taken out of the inner case (200) and the inner case (200) and the outside of the cabinet (100) will be in a state of equilibrium. This is because even after the door is opened, if the guide hole (481) and the outside air duct (370) are opened, foreign substances may be introduced into the inner case (200) and the circulation duct (320).

[0347] Alternatively, the control unit may be provided with an option to set a hot air mode to be performed when a command to perform the drying course is input through an input unit or an external terminal provided on the door (400) and the drying course is completed. For example, the hot air mode may be performed until the door is opened when the drying course is completed. When the door is opened, it is expected that clothing will be taken out of the inner case (200) and the inner case (200) and the outside of the cabinet (100) will be in an equilibrium state. This is because even after the door is opened, if the guide hole (481) and the outside air duct (370) are opened, foreign substances may be introduced into the inner case (200) and the circulation duct (320).

[0348] Meanwhile, the hot air mode performed after the above drying course is completed may have a different duration or operating rate of the compressor (342) and blower fan (352) from the hot air mode performed during the above drying course.

[0349] That is, since it is sufficient to remove the moisture remaining inside the inner case (200) and the circulation duct (320) and lower the relative humidity after the drying course is finished, the hot air mode performed after the drying course is finished can have at least one of the operating time, operating rpm, and actual operating rate of the compressor (342) and the blower fan (352) set to be smaller than the hot air mode performed while the drying course is being performed.

[0350] Therefore, the hot air mode performed after the above drying course is completed can be defined as a storage mode because it keeps the clothes in a refreshed state and prevents the humidity of the inner case (200) and the circulation duct (320) from rising above a standard value.

[0351] Meanwhile, after the drying course is completed, the steam mode can be prevented from being performed. This prevents the absolute humidity inside the inner case (200) and the circulation duct (320) from increasing after the drying course is completed.

[0352] Of course, in order to remove wrinkles, the steam mode may be performed intermittently after the drying course ends, but in this case, the storage mode may be performed immediately after the steam mode ends, thereby preventing the absolute humidity inside the inner case (200) and the circulation duct (320) from increasing. Meanwhile, the control unit may be set to selectively perform the storage mode and the outdoor mode.

[0353] Therefore, when the above storage mode is set to be performed, the above external mode can be blocked from being performed.

[0354] Additionally, if the external mode is set to be performed, the storage mode may be blocked from being performed.

[0355] Of course, the control unit may be set to sequentially perform the storage mode and the external mode. That is, when the storage mode is terminated, the external mode may be subsequently performed.

[0356] When the above control unit performs the external mode, the door damper (460) can be controlled to open the guide hole (481).

[0357] Accordingly, the inside of the inner case (200) and the outside of the cabinet (100) are connected, so that moisture inside the inner case (200) can pass through the door (400) and be discharged to the outside of the cabinet (100).

[0358] When the above control unit performs the above external mode, the external damper (373) may be controlled to open the external air intake unit (322). Accordingly, the inside of the circulation duct (320) is connected to the outside of the cabinet (100) through the outside air duct (370) and the machine room (300), so that the moisture inside the circulation duct (320) can be discharged to the outside of the cabinet (100) through the outside air duct (370) or the inner case and the door. In addition, the outside air duct (370) and the inlet hole (481) are all open, so that a path can be formed through which the outside air of the cabinet (100) is introduced into the clothing treatment device, circulated, and discharged. Accordingly, due to the temperature difference and pressure difference between the outside of the cabinet (100) and the inner case (200) and the circulation duct (320), the air can be introduced from the outside air duct (370) and discharged to the outside of the cabinet (100) through the circulation duct (320) and the inner case (200) through the door chamber (c), or the air can be discharged to the outside of the cabinet (100). It may be introduced from the door chamber (c) and discharged to the outside air duct (370) through the inner case (200) and the circulation duct (320).

[0359] Of course, the control unit can also control the outside air damper (373) to close the outside air intake (322) when the outside air mode is performed. As a result, all moisture evaporated inside the circulation duct (320) or the inner case (200) can be induced to rise and discharged to the outside through the inlet hole (481).

[0360] The above control unit can control the inflow damper (364) to close the entire inflow duct (361) when the outside air mode is performed. As a result, the air flowing in from the outside air duct (370) can be induced to be completely discharged through the discharge hole (232), and moisture in the inner case (200) can be prevented from flowing back into the circulation duct (320) or the blocking filter (366).

[0361] The above control unit may not operate the blower fan (352) and the compressor (342) when the outside mode is performed. As a result, after the drying course is completed, it is possible to prevent the humidity inside the inner case (200) and the circulation duct (320) from rising above a reference value while minimizing energy consumption.

[0362] Of course, the control unit may intermittently and continuously drive the blower fan (352) when the outside air mode is performed. As a result, a path for the outside air of the cabinet (100) to circulate and discharge through the machine room (300) and inner case (200) can be easily formed, moisture can be easily discharged, and the heat exchanger and blocking filter can also be kept dry.

[0363] Through the above-mentioned external mode, the humidity inside the inner case (200) and the circulation duct (320) is prevented from rapidly increasing or rising above a standard value, so that the inside of the circulation duct (320) and the inner case (200) can be maintained in a dry state, and contamination of clothing can also be prevented.

[0364] Meanwhile, when the storage mode of the clothing treatment device of the present invention is performed, the inlet damper (364) is controlled to open the inlet duct (361), the outside air damper (373) is controlled to close the outside air duct (370), and the door damper (460) can be controlled to close the guide hole (481).

[0365] In this way, it is possible to fundamentally block the air outside the cabinet from flowing into the inner case (200) and the machine room (300).

[0366] When the storage mode is performed, the control unit can drive the blower fan (352) and the compressor (342). As a result, hot air is supplied into the inner case (200), so that the relative humidity inside the inner case (200) is lowered, and as a result, the clothes can be maintained in a dry state, and moisture existing inside the inner case (200) can be condensed and removed in the evaporator.

[0367] When the storage mode is performed, the control unit may drive a drain pump to collect water collected in the circulation duct (320) into the drain tank (302). As a result, the air inside the inner case (200) and the air inside the circulation duct (320) can be continuously circulated and dehumidified, and the condensed water can be collected in the drain tank (301).

[0368] Accordingly, the clothes placed in the inner case (200) can be maintained in a dry state, and the inside of the inner case (200) and the circulation duct (320) can be prevented from rotting.

[0369] As described above, the control unit can intermittently drive the compressor (342) while the storage mode is being performed. That is, since the purpose of the storage mode is not to process clothing but to prevent clothing and the inside of the inner case (200) from becoming over-humidified, the compressor (342) can be temporarily driven to prevent the humidity inside the inner case (200) from increasing.

[0370] For example, the compressor (342) may be set to stop for a longer time than the operating time during the storage mode. For example, the compressor (342) may be controlled to operate for 1 minute and stop for 5 minutes, or to operate for 3 minutes and stop for 10 minutes.

[0371] The above control unit can drive the compressor (342) and the blower fan (352) together when the storage mode is performed. The control unit can be set to drive the blower fan (352) simultaneously when the compressor (342) is driven.

[0372] The above control unit can control the second inflow damper (3642) to close the second inflow duct (3622) and the first inflow damper (3641) to open the inflow duct (3621) as shown in FIG. 13 when the above storage mode is performed. As a result, dehumidification can be performed up to the blocking filter (366).

[0373] Alternatively, the control unit may control the second inflow damper (3642) to open and the first inflow damper (3641) to close the inflow duct (361) as shown in FIG. 14 when the storage mode is performed. This prevents moisture in the inner case (200) from being exposed to the blocking filter (366).

[0374] FIG. 17 illustrates an embodiment of a control method for performing a drying course and a communication course when the drying course is completed in the garment treatment device of the present invention. The garment treatment device of the present invention can perform a course completion step (A1) for completing the drying course when the drying course is performed. The course completion step (A1) can be viewed as a step for confirming that the drying course is completed.

[0375] The above control unit can perform a check step (A2) to check whether there is a command or setting to perform the above storage mode.

[0376] If a command to perform the storage mode is input from the input unit in the above inspection step (A2) or the control unit is set to perform the storage mode, the control unit can perform a post-processing step (A3) of performing the storage mode.

[0377] When the above post-processing step (A3) is performed, the control unit can perform a duct opening step (A3-1) that controls the inflow damper (364) so ​​that the inflow duct (361) is opened, a door closing step (A3-2) that controls the door damper (460) so that the guide hole (481) is closed, and an outside air closing step (A3-3) that controls the outside air damper (373) so that communication between the outside air duct (370) and the outside of the cabinet (100) is blocked.

[0378] The above control unit can perform a heating step (A3-4) for driving the compressor (342) and a blowing step (A3-5) for driving the blowing fan (352) when the door chamber and the outside air duct are closed and the inlet duct is opened.

[0379] The above heating step (A3-4) and the above blowing step (A3-5) may be performed continuously while the above post-processing step (A3) is performed.

[0380] Alternatively, the heating step (A3-4) and the blowing step (A3-5) may be intermittently performed while the post-processing step (A3) is being performed. The heating step (A3-4) and the blowing step (A3-5) may be paused for a longer time than the time for which the post-processing step (A3) is performed. This prevents the clothing from being overdried and saves energy.

[0381] Meanwhile, if there is no command or setting for performing the storage mode in the inspection step (A2), the control unit can perform a confirmation step (A4) for detecting whether a command for performing the external mode has been input or whether there is a setting for performing the external mode.

[0382] Even in the above confirmation step (A4), if there is no input or setting of a command for performing the external mode, the control unit may maintain the course as it is in the finished state and the power supply may be cut off.

[0383] Alternatively, if there is an input or setting of a command for performing the external mode in the above confirmation step (A4), the external circulation step (A5) for performing the external mode can be performed.

[0384] Alternatively, if there is no command or setting for performing storage mode in the inspection step (A2), the control unit may be set to automatically perform the external air circulation step (A5) by omitting the confirmation step (A4) itself.

[0385] When the above-mentioned outside air circulation step (A5) is performed, the control unit can perform a duct closing step (A5-1) that controls the inflow damper (364) so ​​that the inflow duct (361) is closed, a door opening step (A5-2) that controls the door damper (460) so that the guide hole (481) is opened, and an outside air opening step (A5-3) that controls the outside air damper (373) so that the outside air duct (370) and the outside of the cabinet (100) are connected.

[0386] The above control unit can perform a stop step (A5-4) that blocks the operation of the compressor (342) in the external air circulation step (A5). That is, the situation in which the compressor (342) is operated again in the external air circulation step (A5) after the drying course is completed can be completely omitted.

[0387] The above control unit may also perform a blocking step (A5-5) that blocks the operation of the blower fan (352) in the above external air circulation step (A5). This makes it possible to block the humidity control inside the inner case (200) from being controlled while consuming separate energy in the above external air mode.

[0388] However, unlike the illustrated embodiment, the control unit may also perform a circulation step of driving the blower fan (352) in the external air circulation step (A5). This allows moisture inside the inner case (200) and the circulation duct (320) to be easily discharged.

[0389] The above circulation step may be performed intermittently while the external air circulation step (A5) is being performed. The pause time of the circulation step may be set to be longer than the time for which the external air circulation step (A5) is performed. This eliminates the misconception that the garment treatment device is still operating after the cycle has ended, and also saves energy.

[0390] FIG. 18 illustrates an additional embodiment of a control method for performing a drying course and a communication course when the drying course is completed in the clothing treatment device of the present invention. The clothing treatment device of the present invention can perform the communication course in the dehumidifying mode when the drying course is completed.

[0391] The control unit of the clothing treatment device of the present invention can be controlled to selectively perform either the storage mode or the dehumidification mode of the communication course when the drying course is finished.

[0392] The above storage mode can lower the humidity and temperature of the inner case (200) and the circulation duct (320) by increasing the temperature inside the machine room (300) and the inner case (200) and circulating the air while blocking the communication between the machine room (300), the inside of the inner case (200), and the outside of the cabinet (100).

[0393] The above dehumidification mode, like the outside mode, can lower the humidity and temperature of the inner case (200) and the circulation duct (320) by connecting the machine room (300) and the inner case (200) with the outside of the cabinet (100).

[0394] However, unlike the outdoor mode, the dehumidification mode can operate the compressor (342) and the blower fan (352) by consuming energy. Accordingly, in the process of dehumidifying the outside of the cabinet (100) through the dehumidification mode, the inside of the inner case (200) and the machine room (320) can also be dehumidified, and the clothing can be kept in a refreshed state.

[0395] The above control unit may be set to automatically perform at least one of the storage mode and the dehumidification mode when the drying course is completed.

[0396] In addition, the control unit can receive a command from a user through the input unit and perform at least one of the storage mode and the dehumidification mode when the drying course is completed.

[0397] For example, the control unit may be configured to automatically perform the dehumidification mode when the drying course is completed. For example, the dehumidification mode may be performed until the humidity outside the cabinet (100) reaches an appropriate level after the drying course is completed.

[0398] The above optimal humidity can be defined as the humidity at which people feel comfortable and clothing remains dry. For example, it can be set to less than 30%.

[0399] Accordingly, the inner case (200) and the inside of the circulation duct (320) can also be dehumidified while the dehumidification mode is performed until the humidity outside the cabinet (100) reaches an appropriate humidity level.

[0400] In addition, during the process of performing the dehumidification mode, the moisture remaining in the inner case (200) and the circulation duct (320) can be discharged into the indoor space by the blower fan (352) and then removed by being introduced into the machine room (300).

[0401] Meanwhile, the dehumidification mode performed after the above drying course is completed can operate the compressor (342) and blower fan (352) differently from the storage mode.

[0402] Since the above dehumidification mode is intended to dehumidify an indoor space, the RPM, operating time, and actual operating rate of the compressor (342) and the blower fan (352) can be operated at a higher rate than in the storage mode.

[0403] Meanwhile, the control unit can be set to selectively perform the storage mode and the dehumidification mode.

[0404] When the above storage mode is set to be performed, the dehumidification mode may be prevented from being performed. In addition, when the dehumidification mode is set to be performed, the storage mode may be prevented from being performed.

[0405] Of course, the control unit may be set to sequentially perform the storage mode and the dehumidification mode. That is, the storage mode may be performed when the dehumidification mode is terminated.

[0406] Referring to Fig. 18, another embodiment of the present invention may be the same as the embodiment of Fig. 17 in that the post-processing step (B3) is performed when the above drying course is performed.

[0407] That is, the course end step (B1), inspection step (B2), and post-processing step (B3) are the same as the previous embodiment.

[0408] Meanwhile, if there is no command or setting for performing the storage mode in the inspection step (A2), the control unit can perform a setting step (B4) for detecting whether a command for performing the dehumidification mode has been input or whether there is a setting for performing the dehumidification mode.

[0409] Even in the above setting step (B4), if there is no input or setting of a command for performing the external mode, the control unit may maintain the course as it is in the finished state and the power supply may be cut off.

[0410] Alternatively, if there is an input or setting of a command for performing the dehumidification mode in the above setting step (B4), a dehumidification step (B5) for performing the dehumidification mode can be performed.

[0411] Alternatively, if there is no command or setting for performing storage mode in the inspection step (B2), the control unit may be set to automatically perform the dehumidification step (B5) by omitting the setting step (B4) itself.

[0412] When the above dehumidification step (B5) is performed, the control unit can perform a duct closing step (B5-1) that controls the inlet damper (364) so ​​that the inlet duct (361) is closed, a door opening step (B5-2) that controls the door damper (460) so that the guide hole (481) is opened, and an outside air opening step (B5-3) that controls the outside air damper (373) so that the outside air duct (370) and the outside of the cabinet (100) are connected. This may be the same as the outside air circulation step (A5).

[0413] However, the control unit may perform a driving step (B5-4) for driving the compressor (342) in the dehumidifying step (B5). That is, the compressor (342) may be controlled to drive when the inlet damper (364), door damper (460), external damper (373), etc. are operated after the drying course is completed and the flow path of the clothing treatment device is changed.

[0414] The above control unit may also perform a circulation step (B5-5) of driving a blower fan (352) in the dehumidification step (B5). As a result, the process of external air of the cabinet (100) being introduced into the machine room (300), dehumidified and heated, then passing through the inner case (200), dehumidifying the inside of the inner case (200) again, and then being discharged to the outside through the door (120) can be repeated.

[0415] In addition, the inside of the machine room (300) can be prevented from overheating through the above circulation step (B5-5).

[0416] In this way, it is possible to control not only the humidity inside the inner case (200) but also the humidity of the indoor space while consuming separate energy in the dehumidification mode.

[0417] The above driving step (B5-4) and the above circulation step (B5-5) can be performed simultaneously.

[0418] The above circulation step (B5-5) may be performed longer than the above driving step (B5-4). When the compressor (342) is driven, the blower fan (352) is driven, but when the blower fan (352) is driven, the compressor (342) may not be driven. As a result, the inner case (200) and the machine room (300) can be prevented from overheating, and moisture can be prevented from condensing and remaining during cooling.

[0419] Figure 19 illustrates an embodiment in which a dehumidification course is performed independently of a drying course in a clothing treatment device of the present invention.

[0420] Meanwhile, the clothing treatment device of the present invention can perform a dehumidification course that performs the dehumidification mode regardless of the drying course.

[0421] That is, the clothing treatment device of the present invention may be set to perform a dehumidification course in which clothing is not placed inside the inner case (200) or the dehumidification mode is performed for the purpose of dehumidifying an indoor space rather than for the purpose of refreshing clothing inside the inner case (200).

[0422] The clothing treatment device of the present invention can be set to perform either a drying course or a dehumidifying course.

[0423] For example, the clothing treatment device of the present invention may be equipped to select either a drying course or a dehumidifying course through an input unit or an external terminal, and when the dehumidifying course is selected, the dehumidifying course may be performed immediately regardless of whether the drying course is performed.

[0424] Accordingly, the user can use the clothing treatment device of the present invention without using a dehumidifier or air conditioner to dehumidify an indoor space.

[0425] Meanwhile, since the garment treatment device of the present invention can perform the dehumidification course regardless of whether the door (120) is opened, the user can input the power supply of the garment treatment device of the present invention and select and perform the dehumidification course without opening the door (120).

[0426] To this end, the clothing treatment device of the present invention can perform a selection step (C1) of checking whether the dehumidification course is selected when a power supply unit receiving a command to supply power is input.

[0427] If the dehumidification course is not selected in the above selection step (C1), it may wait until the drying course or dehumidification course is selected.

[0428] If a dehumidification course is selected in the above selection step (C1), the clothing treatment device of the present invention can perform a dehumidification performance step (C2) that performs the dehumidification mode.

[0429] The above dehumidification step (C2) can be set identically to the above dehumidification step (B5).

[0430] That is, a duct closing step (C2-1) for controlling the inlet damper (364) so ​​that the inlet port (361) is completely closed, a door opening step (C2-2) for controlling the door damper (460) so that the guide hole (481) is opened, and an outside air opening step (C2-3) for controlling the outside air damper (373) so that the outside air duct (370) and the outside of the cabinet (100) are connected can be performed. This can be the same as the outside air circulation step (A5).

[0431] Additionally, a driving step (C2-4) for driving the compressor (342) and a circulation step (C2-5) for driving the blower fan (352) can be performed.

[0432] The control contents of the corresponding step may be identical to the above dehumidification step (B5).

[0433] The present invention may be implemented in various modified forms, and its scope is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
