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] If you wash clothes frequently with water and detergent, the clothes may become damaged or deformed.

[0004] To address this, a garment treatment device has emerged that can perform a so-called refreshing process, removing wrinkles or odors from clothes or rearranging the fiber arrangement of clothes by spraying steam on the clothes without wetting them and evaporating it with high-temperature air. (Refer to Korean Patent Publication No. 10-2021-0144451)

[0005] The garment treatment device may also be called a garment management device, and the garment treatment device may be equipped to place the garment without folding or wrinkling it and supply at least one of hot air and steam to the garment.

[0006] Previously, a garment treatment device was developed that vibrated the garment, actively exposing its surface to steam / hot air and removing dust and foreign substances from the garment. (Korean Patent No. 10-1285890)

[0007] Recently, a garment treatment device has emerged that features a steam iron that can be removed from the machine and directly heat or pressurize the surface of the garment. This allows users to place garments inside the machine and then use the "refresh" cycle to maintain their condition. Alternatively, they can place garments inside the machine or against a door or wall, then remove the steam iron to directly apply steam and heat to the garments, removing wrinkles.

[0008] Recently, a garment treatment device has appeared that has a machine room including a refresh module (T) that supplies hot air to the hung garments and circulates it again to condense the dried water in the garments, and an ironing module (S) that has a steam iron (I) that directly supplies steam and hot air to the surface of the garments.

[0009] This garment treatment device is equipped with a steam supply unit (T1) that supplies steam to a space where garments are placed and a steam generation unit (S1) that supplies steam to a steam iron, and a water supply pump (T2) that supplies water to the steam supply unit (T1) and a high-pressure pump (S2) that supplies water to the steam generation unit (S1) are equipped separately.

[0010] Accordingly, the conventional clothing treatment device had the advantage of being able to selectively supply steam to the space where the clothing is placed and the steam iron (I), but had the disadvantage of having to have multiple components for heating water and also having to have multiple components for supplying water.

[0011] Because of this, the conventional clothing treatment device had a fundamental problem that included a production problem in which the manufacturing process was delayed and installation costs increased because all of the components had to be placed in the machine room, a management problem in which maintenance became difficult because the number of components that had to be maintained and repaired increased, and a control problem in which excessive current was consumed when the steam supply unit (T1) and the steam generation unit (S1) were controlled separately or simultaneously.

[0012] In addition, since the steam supply unit (T1) is generally equipped to spray steam with a lower pressure than the steam generation unit (S1), the conventional clothing treatment device always supplies only steam with a lower pressure than the steam iron (I) to the space where the clothing is placed, making it difficult to supply sufficient steam to the clothing, or there was also a problem that a lot of time was needed for the clothing to be exposed to sufficient steam.

[0013]

[0014] The present invention aims to provide a garment treatment device that can reduce the manufacturing process of the garment treatment device and lower the manufacturing cost, and that includes an inner case for holding garments and a steam iron for spraying steam.

[0015] The present invention aims to provide a garment treatment device that can be easily installed and maintained even when equipped with a refresh module that circulates air inside an inner case and an ironing module (T) that includes a steam iron.

[0016] The present invention aims to provide a clothing treatment device capable of simplifying the configuration of a machine room in which a refresh module and an ironing module are installed.

[0017] The present invention aims to provide a garment treatment device capable of controlling the pressure of steam sprayed to the inner case.

[0078] The cabinet (100) may be provided with a height longer than the width in the left-right direction and the thickness in the front-back direction. Accordingly, the garment treatment device may be installed inside the cabinet (100) without folding even long garments.

[0079] The above installation body (122) can be extended from the main body (121) toward the rear of the cabinet (100) to form a step.

[0080] The above installation body (122) may be provided with a different material or color than the main body (122). In addition, the above installation body (122) may be provided with a translucent material through which light emitted from the display can be transmitted.

[0081] A handle (123) may be provided in the stepped area of ​​the above-mentioned installation body (122) and the main body (121).

[0082] The handle (123) may be provided to extend from one side of the main body (121) toward the front of the installation body (122) in parallel with the main body (121). As a result, the handle (123) may be arranged to overlap at least a portion of the installation body (122) in the front-back direction, and may form a space that a user can grip.

[0083] The above cabinet (100) and the above door (120) may be made of metal.

[0084] Figure 2 illustrates the interior of the cabinet of the garment treatment device of the present invention.

[0085] The cabinet (100) may be provided with an inner case (200) that has a storage space (220) for storing clothing and forms an opening (210) in the front through which clothing is inserted.

[0086] The inner case (200) above is a rectangular parallelepiped shape with an opening at the front, and may be provided with a height smaller than that of the cabinet (100). As a result, an area in which a machine room (300) described below can be installed can be secured below the cabinet (100).

[0087] The inner case (200) may be provided with a height greater than its width and thickness. This allows the clothing to be placed inside the storage space (220) without being folded or wrinkled.

[0088] The inner case (200) above may be provided with a plastic resin series, and may be provided with a reinforced plastic resin series that does not deform even when exposed to air at a temperature higher than room temperature or heated air (hereinafter, hot air) and steam or moisture.

[0089] A mounting portion for mounting the garment in the receiving space (220) may be provided on the upper part of the inner surface of the inner case (200). The mounting portion may be provided in the shape of a clothes hanger and may be fixed to the upper surface of the inner case (200). Due to the mounting portion, the garment may be placed in the receiving space (220) in an unfolded state and in a state floating in the air.

[0090] The above-mentioned mounting portion may be provided in multiple numbers along the width direction of the inner case (200). As a result, multiple garments can be mounted spaced apart from each other inside the inner case (200).

[0091] The above-mentioned holding member may be provided as a moving hanger that moves back and forth in the width direction within the inner case (200) or rotates back and forth. The garment treatment device of the present invention can shake the garment within the inner case due to the holding member, and while the garment is moved within the receiving space (220), foreign substances and dust can be shaken off, and wrinkles formed on the garment can also be removed.

[0092] The clothing treatment device of the present invention may be equipped with a machine room (300) in which various devices capable of supplying high temperature air or heated air (hereinafter referred to as hot air) to the receiving space (220), supplying one or more steams to the receiving space (220), or purifying or dehumidifying the external air of the cabinet (100) are installed.

[0093] The above machine room (300) may be arranged to be separated or partitioned from the inner case (200), but may be provided to communicate with the receiving space (220).

[0094] The above-mentioned machine room (300) may be placed at the bottom of the inner case (200). Thus, when hot air and steam having a low specific gravity are supplied to the inner case (200), the hot air and steam can naturally rise in the receiving space (220) and be supplied to the placed clothing.

[0095] The inner case (200) can be partitioned and separated from the machine room (300) through the bottom surface (230). However, a plurality of through holes may be arranged in the bottom surface (230) to enable communication with the machine room (300).

[0096] To this end, the inner case (200) may be provided with a plurality of through holes (230) that penetrate one surface and communicate with the machine room (300).

[0097] Through the above-mentioned through hole (230), air in the receiving space (220) can be supplied to the machine room (300), and at least one of hot air or steam generated in the machine room (300) can be supplied to the receiving space (220).

[0098] The above-mentioned through hole (230) may include an inlet hole (232) penetrating the bottom surface (230) of the inner case (200) through which air inside the inner case (200) is discharged or sucked into the machine room (300), and an exhaust hole (231) penetrating the lower surface of the inner case (200) through which hot air generated in the machine room (300) is discharged.

[0099] The above discharge hole (231) may be arranged to be tilted toward the rear of the lower surface of the inner case (200). In addition, the above inlet hole (232) may be arranged to be tilted toward the front of the lower surface of the inner case (200). Accordingly, a distance between the inlet hole (231) and the discharge hole (232) on the bottom surface (230) of the inner case (200) can be secured, and hot air supplied from the discharge hole (232) can be prevented from being directly discharged to the inlet hole (231).

[0100] The above-described through hole (230) may further include a steam hole (233) to which steam generated from the steam supply unit (800) described below is supplied. It may be arranged closer to the discharge hole (231) than to the inlet hole (232). For example, the steam hole (233) may be arranged on one side of the discharge hole (231). This can prevent steam discharged from the steam hole (233) from directly flowing into the inlet hole (232).

[0101] The above door (120) can be rotatably coupled to the above cabinet (100).

[0102] The height of the door (120) may be provided to correspond to the height of the cabinet (100). Accordingly, the door (120) may be provided to open and close the opening (210) and may also be provided to shield the machine room (300).

[0103] When the above door (120) is closed, the opening (210) and the machine room (300) can be prevented from being exposed to the front.

[0104] The above door (120) may include a door body (121) forming the main body and a sealing member (123) coupled to the inner surface of the door body (121) to seal the opening (210).

[0105] The above sealing member (123) may be arranged in an area facing the perimeter of the opening (210) on the inner surface of the door body (121) to seal the opening (210).

[0106] Meanwhile, the door body (121) may include a protective panel (122) that shields the machine room (300) and protects the machine room (300) at the lower portion of the sealing member (123) that seals the opening (210).

[0107] The above sealing member (123) may be provided to extend further downward than the opening (210) so as to seal the front perimeter of the machine room (300).

[0108] The above door (120) may include a protrusion (125) that protrudes from the inside of the door body (121) and can be inserted at least partially into the opening (210).

[0109] The above protrusion (125) may be provided to protrude from the door body (121) to such an extent that it is positioned in front of the inlet hole (232) when the door (120) closes the opening (210).

[0110] The above protrusion (125) may be provided with a width corresponding to the width of the opening (210). The above protrusion (125) may be positioned closer to the lower portion of the opening (210) or the bottom surface (230) of the inner case (200) than to the upper portion of the door body (121).

[0111] In this way, it is possible to guide the hot air and steam placed in the receiving space (220) of the inner case to flow into the inlet hole (232), and prevent them from flowing out of the opening (210) and being exposed to the machine room (300).

[0112] The height of the protrusion (125) may be formed to be smaller than 1 / 3 of the height of the inner case (200), and the thickness of the protrusion (125) protruding from the door body (121) may be formed to be smaller than the distance from the front edge of the bottom surface (230) to the inlet hole (232).

[0113] The door body (120) may further include a curved surface (124) extending toward the protrusion (125) on the inner surface. The curved surface (124) may be provided in a downward convex shape. The curved surface (124) may induce hot air and steam supplied to the receiving space (220) to circulate within the receiving space (220).

[0114] The clothing treatment device of the present invention may include a pressurizing part (130) that is rotatably coupled to the inner surface of the door body (121) to pressurize clothing, and a fixing part (140) that can hold the clothing above the pressurizing part (130).

[0115] The above pressurizing part (130) is provided to rotate in the width direction of the door (120) and can pressurize clothing placed on the fixing part (140).

[0116] In this way, by pressing the clothing placed on the fixing member (140) with the pressing member (130), wrinkles in the clothing can be removed, and intended wrinkles can be formed in the clothing.

[0117] The above curved surface (124) may be provided to extend from the lower portion of the pressurizing portion (130) to the protrusion (125). As a result, when water condensed from clothes placed on the fixing portion (140) flows along the inner surface of the pressurizing portion (130) or the door body (121), it can be prevented from flowing along the curved surface (124) to the bottom surface (230) and moving to the opening (210) or the sealing member (123). As a result, the machine room (300) can be prevented from being contaminated with water, steam, hot air, foreign substances, etc.

[0118] The above protrusion (125) may have an exposed surface arranged parallel to the back surface of the inner case (200), and a lower surface extending from the lower portion of the exposed surface may be arranged parallel to the bottom surface (230) of the inner case.

[0119] The exposed surface of the above protrusion (125) may be provided with a penetration surface (126) through which air can pass, and a duct through which the air can flow may be provided in the space formed by the protrusion (125), the curved surface (124), and the door body (121).

[0120] The above door body (121) may be provided with a communication hole communicating with the duct in an area corresponding to the pressurizing portion (130) on the inner surface.

[0121] In this way, hot air and steam flowing in the inner case (200) are introduced into the through hole (126) and discharged through the communication hole, thereby drying clothes placed on the pressurized portion (130) or circulating the air inside the inner case (200).

[0122] Figure 3 illustrates the exterior of the machine room (300).

[0123] The above-mentioned machine room (300) is equipped to supply at least one of hot air and steam to the inner case (200). To this end, the machine room (300) must be supplied with water necessary to generate the steam, and must be equipped to collect steam supplied to the inner case (200) or water condensed from clothing.

[0124] To this end, the machine room (300) may include a water tank (301) for storing water used for steam, and a drain tank (302) for collecting water condensed inside the garment treatment device.

[0125] The above water supply tank (301) and the above drain tank (302) can be placed in front of the machine room (300). This makes it easy to fill the water supply tank (301) with water or empty the water in the drain tank (302), and the clothing treatment device can be placed without being restricted by the location of the water source and drain.

[0126] The garment treatment device of the present invention may include an iron module (S) in which a steam iron (1300) is installed.

[0127] The above ironing module (s) can be installed in the machine room (300).

[0128] The above ironing module (S) may be provided to supply heat and steam to the surface of the clothing.

[0129] The above ironing module (S) may further include a storage unit (1200) for storing a steam iron (1300) capable of spraying or supplying at least one of heat and steam to the surface of clothing inside the machine room (300).

[0130] The above storage unit (1200) may include a storage body (1210) that is mounted in the machine room (300) and provides a space in which the steam iron (1300) is stored, and an open surface (1220) that is provided on the front of the storage body (1210) and through which the steam iron (1300) is taken out.

[0131] The steam iron (1300) can be withdrawn from the machine room (300) by being withdrawn to the front of the storage body (1210). When the steam iron (1300) is withdrawn to the front of the machine room (300), it can be arranged to reach the surface of the clothing placed on the fixing member (140) or the stand.

[0132] The steam iron (1300) may be provided to transmit heat and steam to a position higher than half the height of the inner case (200), up to the top of the pressurizing portion (130) of the door (120). The steam iron (1300) may be placed in contact with the surface of the clothing or close to the clothing, so as to directly spray heat and steam onto the surface of the clothing.

[0133] For example, the steam iron (1300) may be provided to reach the stand or the fixed part (140). In addition, the steam iron (1300) may be provided to move to the upper surface of the receiving space (220) or the upper part of the inner surface of the door (120) when taken out from the storage part (1200).

[0134] The steam iron (1300) may be configured to supply heat to the surface of clothing, or may be configured to spray steam onto the surface of clothing. The steam iron (1300) may be a standard steam iron or a standard steamer. As long as it satisfies the conditions for removing wrinkles from clothing, the steam iron (1300) may be configured in any configuration.

[0135] The clothing (L) fixed to the above-mentioned stand or fixing member (140) may be supported on the inner surface of the door (120) or the inner surface of the inner case (200) and may be exposed to at least one of heat and steam supplied from the steam iron (1300). In this process, the clothing (L) may be refreshed or wrinkles may be removed.

[0136] The above ironing module (S) may be exposed to the front surface of the machine room (300) because the steam iron (1300) must be pulled out from the machine room (300) to the clothes placed on the inner case (200) or door (120).

[0137] For example, the front surface of the ironing module (S) may be placed on one side of the water supply tank (301) or the drain tank (302), and both sides may be placed inside the machine surface (300).

[0138] The above water supply tank (301) and drain tank (302) can be shared by the iron module (S) and the refresh module (T).

[0139] Figure 4 illustrates the structure of the machine room of the garment treatment device of the present invention.

[0140] The inside of the above machine room (300) may include a refresh module (T) configured to supply hot air and steam to clothes placed in the receiving space (220), circulate air inside the receiving space, or circulate air outside the cabinet, and an ironing module (S) including the steam iron (1300).

[0141] The above refresh module (T) may include all devices and configurations that can supply at least one of hot air and steam to the inside of the inner case (200).

[0142] Specifically, the refresh module (T) may include a base (310) that supports or provides a space for installing the various devices described above in the machine room (300), a circulation duct (320) that is installed or extended from the base (310) and provides a path for moving air inside the inner case (200) or air outside the cabinet (200), a blower (350) that is mounted on the circulation duct (320) and provides power to move the air, and a heat supply unit (340) that cools and heats the air moving along the circulation duct (320) to generate hot air.

[0143] The above base part (310) may be provided as a plate on which various devices are installed.

[0144] The above circulation duct (320) forms a path through which air flowing in from outside the inner case (200) or the cabinet (100) moves, and may be provided in the shape of a case with an open upper surface.

[0145] The heat supply unit (340) may include a heat exchanger that is arranged inside the circulation duct (320) to cool the air, condense moisture, and reheat the air, and a compressor that is arranged outside the circulation duct (320) to receive refrigerant from the heat exchanger or supply refrigerant.

[0146] The above refresh module may further include an outside air duct (370) that draws in outside air in front of the circulation duct (320) and guides it into the inside of the circulation duct (320).

[0147] The above circulation duct (320) is provided to communicate with the outside air duct (370) and can be provided to selectively suck in outside air.

[0148] The above water supply tank and the above drain tank may also be included in the above refresh module (T).

[0149] The water supply tank and drain tank can be detachably connected to the front of the above circulation duct (320). For example, the water supply tank (301) and drain tank (302) can be installed and arranged on the upper part of the outside air duct (370).

[0150] The above circulation duct (320) may be provided by being coupled to the base portion (310), but may also be provided as an integral part with the base portion (310). For example, the base portion (310) and the circulation duct (320) may be manufactured simultaneously through injection molding.

[0151] The above refresh module (T) may include a base cover (360) provided to connect the circulation duct (320) and the inlet hole (232).

[0152] The above base cover (360) may be coupled to the upper portion of the circulation duct (320) to guide air sucked in from the inlet hole (232) into the interior of the circulation duct (320).

[0153] The above base cover (360) can block the upper surface of the circulation duct (320) to prevent air inside the circulation duct (320) from being discharged to the outside. The lower portion of the base cover (360) and the upper surface of the circulation duct (320) can form one side of the flow path of the circulation duct (320).

[0154] The above base cover (360) may include an inlet portion (362) that connects the inlet hole (232) and the circulation duct (320) therein. The inlet portion (362) is provided in a duct shape and may function as an intake duct that delivers air inside the inner case (200) to the circulation duct (320).

[0155] The above blower (350) may be provided to communicate with the circulation duct (320) and the discharge hole (231).

[0156] The iron module (S) may be placed on the left or right side of the refresh module (T) inside the machine room (300). Specifically, the iron module (S) may be placed outside the circulation duct (320). As a result, the iron module (S) may not obstruct the air flow flowing through the circulation duct (320).

[0157] Meanwhile, the clothing treatment device of the present invention may further include a steam nozzle (900) that receives steam and is placed on the bottom surface of the inner case (200) to supply steam to the inside of the inner case (200).

[0158] The above steam nozzle (900) may be arranged on the bottom surface of the steam hole (233) and may be provided to communicate with the steam hole (233).

[0159] The above steam nozzle (900) is provided in a case shape with a width longer than the front-rear width, so that the supplied steam can be guided to be supplied to the entire inner case (200) and the transmitted steam can be prevented from leaking into the machine room (300).

[0160] The above ironing module (S) can be arranged parallel to the length direction of the circulation duct (320) on one side of the base part (310).

[0161] The above ironing module (S) can be placed on one side of the circulation duct (320).

[0162] The above iron module (S) may include a steam iron (1300) and a heating unit (2100) that supplies steam to the steam iron (1300).

[0163] The above heating unit (2100) may be provided to supply steam not only to the steam iron (1300) but also to the inner case (200).

[0164] The above iron module (S) may include a cable (1400) that extends from the heating unit (2100) to the steam iron (1300) to supply steam generated in the heating unit (2100), and a guide pipe (1500) that extends from the heating unit (2100) to the bottom surface of the inner case (200) or the steam nozzle (900) to supply steam generated in the heating unit (2100). As a result, the refresh module (T) and the iron module (S) may share one heating unit (2100).

[0165] In addition, since the steam iron (1300) is generally equipped to supply steam above atmospheric pressure, the heating unit (2100) may be equipped to generate high-pressure steam. Since the heating unit (2100) can also supply steam to the inside of the inner case (200), high-pressure steam can also be supplied to the inner case (200). As a result, sufficient steam can be supplied to the clothes placed in the inner case more quickly, and thus the time for supplying steam to the inside of the inner case (200) can be reduced. Accordingly, the time for performing the refresh cycle can also be reduced, and energy can also be saved.

[0166] Therefore, due to the heating unit (2100), the refresh module (T) can omit a separate steam generating device.

[0167] The configuration itself for supplying steam to the upper surface of the circulation duct (320) may be omitted. In this case, the distance between the upper surface of the circulation duct (320) and the bottom surface of the inner case (200) may be increased. Accordingly, the influence of the air flowing through the circulation duct (320) or the heat supply unit accommodated in the circulation duct (320) on the bottom surface of the inner case (200) can be minimized.

[0168] The above heating unit (2100) can be placed on the back of the steam iron (1300). Accordingly, the overall volume of the refresh module (T) can be reduced, so that the manufacturing, installation, as well as maintenance and repair of the refresh module (T) can be simplified.

[0169] In addition, since the overall configuration of the machine room (300) is relatively simple and the volume is reduced, the installation, maintenance, and repair of the iron module (S) can also be simplified.

[0170] Meanwhile, the heating unit (2100) may further include a valve unit (2800) that determines whether to supply steam to the steam iron (1300) and the inner case (200).

[0171] The garment treatment device of the present invention can control the valve unit (2800) to determine whether steam will be supplied to the inner case (200) and the steam iron (1300).

[0172] As a result, even if steam is generated in the heating unit (2100), it can be prevented from being arbitrarily supplied to the inner case (200) and the steam iron (1300).

[0173] Figure 5 illustrates the rear of the machine room.

[0174] The above blower (350) may include a blower fan (353) that provides power for the air inside the circulation duct (320) to move in one direction, and a fan housing (351) that accommodates the blower fan (353) and is coupled to or extended from the circulation duct (320).

[0175] The above blower (350) may be equipped with an exhaust duct (352) that is provided to communicate the circulation duct (320) and the exhaust hole (232).

[0176] The above exhaust duct (352) may be provided so as to extend toward the exhaust hole (232) in the fan housing (351) with a cross-section corresponding to the area of ​​the exhaust hole (232).

[0177] As a result, the air inside the inner case (200) can be introduced through the base cover (360), pass through the circulation duct (320), and then be supplied back into the inner case (200) through the fan installation part (350).

[0178] The heat supply unit (340) may include a compressor (343) installed in the base unit (310) and exchanging heat with air flowing through the circulation duct (320). The compressor (343) may be placed on the left or right side of the circulation duct (320), and may be placed between the circulation duct (320) and the iron module (S).

[0179] Figure 6 illustrates the circulation duct and base structure in the machine room of the garment treatment device of the present invention.

[0180] The above base portion (310) can form the lower surface of the clothing treatment device.

[0181] The above base portion (310) may include a base bottom portion (311) forming a support surface. The base bottom portion (311) may form the lower surface of the garment treatment device.

[0182] Of course, the base bottom part (311) can be installed on the upper surface of the bottom surface of a cabinet (100) separately provided to form the lower surface of the clothing treatment device.

[0183] The above base portion (310) may be integrally provided with the circulation duct (320) that forms at least a portion of the path through which air moves. The circulation duct (320) may be formed by extending upward from the base bottom portion (311).

[0184] The above circulation duct (320) may include a duct body (321) that extends from the base bottom portion (311) to form a flow path, a heat exchanger installation portion (3212) that provides a space in which an evaporator (341) or a condenser (343) is installed inside the duct body (321), and an air discharge portion (323) that is provided at the rear of the duct body (321) and discharges air in the duct body (321) to a blower portion (350).

[0185] The above air discharge unit (323) may be provided in the shape of a pipe extending rearward from the duct body (321). The diameter of the air discharge unit (323) may be provided to be smaller than the width of the duct body (321).

[0186] The above air discharge unit (323) can be connected to the above blower unit (350). Air discharged from the air discharge unit (323) can be guided into the inner case (200) through the blower unit (350).

[0187] The above circulation duct (320) may further include an outside air intake portion (322) formed by penetrating the front of the duct body (321). The outside air intake portion (322) may be provided to communicate with the outside air duct (370). The outside air duct (370) may be supported by being installed in front of the outside air intake portion (322).

[0188] The above circulation duct (320) may be equipped with a damper that opens and closes the outside air intake section (322). Opening and closing the damper allows or blocks outside air from flowing into the inside of the circulation duct (320).

[0189] The above base part (310) may include a compressor installation part (312) that provides a space in which the compressor (343) is installed. The compressor installation part (312) may be formed on one side of the base bottom part (311) and may be formed integrally with the base bottom part (311).

[0190] The compressor installation part (312) may be formed with a protrusion capable of supporting the compressor (343). The compressor installation part (312) may be positioned to be offset to the rear of the base part (310). The compressor installation part (312) may be positioned so that at least a portion thereof overlaps the air discharge part (323) in the width direction.

[0191] The above compressor installation part (312) may be equipped with a buffer member that reduces vibration transmitted from the compressor (343). The buffer member may be fixed to the protrusion.

[0192] The above base part (310) may be equipped with a compressor installation part (313) in which the compressor (343) that supplies refrigerant to the heat exchanger (341, 343) is installed. The compressor installation part (313) may be placed outside the circulation duct (320).

[0193] The above iron module (S) may be mounted on one side of the compressor installation part (312) or the base part (310). The iron module (S) may also be mounted on the base part (310). 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).

[0194] 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).

[0195] Figure 7 illustrates the inside of the circulation duct of the clothing treatment device of the present invention.

[0196] The above circulation duct (320) can extend upward from the base floor to form a flow path through which air flows.

[0197] 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).

[0198] 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.

[0199] 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 (343) 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 (343) 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 (343).

[0200] 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).

[0201] 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).

[0202] The above duct body (321) may be provided with an open upper surface. A condenser (343) and an evaporator (341) may be installed by inserting them through the opening of the duct body (321).

[0203] 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).

[0204] The front surface of the above duct body (321) can be arranged rearwardly 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 one or more of the above-described water supply tank (30) or drain tank (40) and outdoor air duct (370) are installed and supported.

[0205] 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 (343) and the evaporator (341) can also be increased accordingly.

[0206] As a result, the width of the condenser (343) 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.

[0207] Meanwhile, the sum of the length of the evaporator (341) and the length of the condenser (343) 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).

[0208] The above blower (350) can be arranged to overlap the condenser (343) or the evaporator (341) in the front-rear direction. Accordingly, the air that has passed through the evaporator (341) and the condenser (343) 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).

[0209] The length of the above ironing module (S) may be provided to be longer than the length of the above circulation duct (320).

[0210] Figure 8 illustrates the structure of a control unit installation unit provided on the base of the garment treatment device of the present invention.

[0211] The above refresh module (T) may further include a main control unit (700) that supplies power to the heat supply unit (340) and the steam supply unit (800) or controls the heat supply unit (340) and the steam supply unit (800).

[0212] The above main control unit (700) can be placed inside the machine room (300). This allows the volume of the inner case (200) to be secured to the maximum extent possible.

[0213] The above main control unit (700) can be mounted on the base unit (310).

[0214] The above main control unit (700) can be placed outside the circulation duct (320).

[0215] For example, the main control unit (700) may be placed on the left or right side of the circulation duct (320).

[0216] For example, the base portion (310) may be provided with a control unit installation portion (312) that forms a space in which the main control unit (700) can be inserted at the bottom of the circulation duct (320).

[0217] The above base part (310) may include a control part installation part (313) in which the main control part (700) is installed. The control part installation part (313) may be formed between the base bottom part (311) and the circulation duct (320). The control part installation part (313) may be formed between the base bottom part (311) and the bottom surface of the circulation duct (320). The control part installation part (313) may be provided in the shape of a duct that is open at either the front or the rear at the bottom of the circulation duct (320).

[0218] The above main control unit (700) is equipped to be connected to an external power source to receive power, and can be equipped to supply power to all electronically controlled components, such as the compressor (343), the heating unit (2100), and the blower fan (353).

[0219] In addition, the main control unit (700) is equipped to control all electronically controlled components, such as the compressor (343), the heating unit (2100), and the blower fan (353), so that various courses and options for processing clothing can be performed.

[0220] When the main control unit (700) is inserted into and supported by the control unit installation unit (312), vibrations or shocks applied to the main control unit (700) can be buffered. In addition, since the main control unit (700) is positioned close to the electrical components constituting the refresh module (T), the occurrence of control errors such as noise can be minimized.

[0221] The circulation duct (320), the outdoor air duct (370), the main control unit (700), and the heat supply unit (340) can be installed in a module format in the base unit (310). As a result, the base unit (310) can be easily installed and maintained by being pulled in or out from the front or rear of the machine room (300).

[0222] Figure 8(a) illustrates an embodiment in which the main control unit (700) is installed in the control unit installation unit (313).

[0223] The above main control unit (700) may be provided as a PCB board, but is not limited thereto and may be provided as various devices for control.

[0224] The above main control unit (700) can be inserted and installed in the control unit installation unit (313) provided at the lower portion of the circulation duct (320). The bottom surface of the circulation duct (320) can form the upper surface of the control unit installation unit (313). The control unit installation unit (313) can be positioned lower than the air discharge unit (323).

[0225] The above control unit installation part (313) may be formed integrally with the base bottom part (311). The above control unit installation part (313) may be formed as a sunken space at the bottom of the circulation duct during the process of forming the circulation duct (320) in the base part (310).

[0226] The above main control unit (700) can be introduced in a sliding manner from the rear to the front in the control unit installation unit (313).

[0227] The surface of the above main control unit (700) may further be provided with a bracket (3131) that surrounds the control unit. The bracket (3131) may be positioned above and below the control unit to prevent foreign substances from entering the control unit.

[0228] In addition, the bracket (3131) can prevent damage to the circuit board inside the main control unit (700) due to heat or vibration being transmitted to the main control unit (700). The bracket (3131) can be made of a metal material.

[0229] Figure 8(b) illustrates a state in which the control unit is installed in the control unit installation section.

[0230] As shown in the drawing above, the main control unit (700) may be installed at a predetermined angle with respect to the base bottom portion (311). For example, the main control unit (700) may be arranged to be inclined toward the water reservoir (326). Accordingly, when water flows out from the upper portion of the main control unit (700), the water can quickly leave the main control unit (700).

[0231] The above main control unit (700) may include a supporter (3132) that is formed to protrude laterally.

[0232] The above control unit installation part (313) may include ribs (3134) protruding from both sides of the installation part. The supporter (3132) of the control unit may be mounted on the upper side of the ribs (3134).

[0233] The supporter (3132) of the above control unit can support the entire load of the main control unit (700). When the supporter (3132) of the control unit is supported on the upper side of the rib (3134), the main control unit (700) can be spaced apart from the base bottom part (311) by a predetermined distance.

[0234] The above rib (3134) can be formed integrally with the base portion (310). The above rib (3134) can be formed together with the base portion (310) when injection molding, and can be formed integrally with the base bottom portion (311), circulation duct (320), etc.

[0235] The front surface of the main control unit (700) may be provided with a protruding projection (3133). In addition, the inner surface of the control unit installation unit (313) may be provided with a guide protruding backward. The projection may be coupled with the guide. The projection may be inserted into the guide. When the control unit is inserted into the control unit installation unit, the control unit can be aligned in the correct position by coupling the projection to the guide.

[0236] Additionally, the two sides of the control unit can be positioned in such a way that the supporter is secured to the rib, as described above. Using this joining process, the control unit can be joined to the correct position on the control unit installation part without a separate fastener.

[0237] Figure 9 illustrates a water supply and drainage system of the clothing treatment device of the present invention.

[0238] The clothing treatment device of the present invention may include a water supply tank (301) that supplies water to the heating unit (2100) and a drain tank (302) that collects water condensed in the circulation duct (320) or steam iron (1300) and the cable (1400).

[0239] 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).

[0240] 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).

[0241] The above detachable part (380) is provided in a plate shape to prevent the inside of the machine room (300) from being exposed.

[0242] 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).

[0243] The above ironing module (S) may be provided so that a part thereof penetrates the detachable portion (380).

[0244] 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.

[0245] 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.

[0246] Figure 10 illustrates the drainage structure of the clothing treatment device of the present invention.

[0247] When the compressor (343) and the blower fan (352) are driven in the clothing treatment device of the present invention, the air supplied from outside the cabinet (100) and the air supplied from the inner case (200) are cooled while passing through the evaporator (341), and the water vapor contained in the air is condensed.

[0248] The water condensed in the above evaporator (341) may accumulate on the lower surface of the above circulation duct (320).

[0249] The clothing treatment device of the present invention may include a water storage portion (326) provided by sinking a portion of the bottom surface of the duct body (321) to collect condensed water condensed in the evaporator (341).

[0250] The above-mentioned reservoir (326) is a space formed by a depression in the bottom surface of the duct body (321), and may also form one side of the control unit installation portion (313).

[0251] The above reservoir (326) can be formed by sinking downward from the bottom surface of the circulation duct (320).

[0252] The above reservoir (326) can be formed integrally with the circulation duct (320). The reservoir (326) can be created by injection-molding the circulation duct (320) onto the base portion (310) and molding a portion of the bottom surface of the circulation duct (320) to be sunken.

[0253] The above reservoir (326) may have at least a portion of its upper surface arranged parallel to the heat exchanger installation portion (313).

[0254] The above base portion (310) may include a guide pipe (3263) that discharges water collected in the reservoir (326) to the outside.

[0255] The above guide pipe (3263) may be provided so as to protrude from the lower portion of the reservoir (362) to the outside of the circulation duct (320). The guide pipe (3263) may discharge water stored in the reservoir to the outside of the base portion. This may prevent water collected in the reservoir (326) from decaying or flowing back to the bottom surface of the circulation duct (320).

[0256] The above circulation duct (320) is provided with the partition wall (3211) that extends from the inner surface of the duct body (321). The partition wall (3211) may protrude inwardly from the inner wall of the circulation duct (320), or may protrude inwardly by forming the outer wall of the circulation duct (320) to be recessed inwardly. The partition wall (3211) may guide the position where the heat exchanger (341, 343) is installed, and may prevent air entering the heat exchanger from bypassing the heat exchanger. The partition wall (3211) may be provided in the water reservoir (326).

[0257] Figure 11 illustrates the drainage tank installation structure of the clothing treatment device of the present invention.

[0258] The above drainage tank (302) may be provided in a box shape for storing water.

[0259] The above drain tank (302) may be provided with a supply hole on the back surface to receive water, and the supply hole may be positioned closer to the top than the bottom surface of the drain tank (302).

[0260] The above-mentioned detachable part (380) may include a load supporting part (381) capable of supporting at least one of the drain tank (302), the water supply tank (301), and the ironing module (S), and a detachable supporting part (382) disposed in front of the circulation duct (320) on the load supporting part (381) so that the drain tank (302) and the water supply tank (301) can be installed.

[0261] The above load support member (381) is provided in a plate shape and can support the lower surface of the water supply tank (301) and the drain tank (302), and the detachable support member (382) is also provided in a plate shape and can be provided to support the back surface of the water supply tank (301) and the drain tank (302).

[0262] The above-mentioned detachable portion (380) may include a detachable separating portion (383) protruding from the load supporting portion (381) so as to be positioned between the water supply tank (301) and the drain tank (302). The detachable separating portion (383) may space the water supply tank (301) and the drain tank (302) apart by a predetermined distance. Accordingly, when one of the water supply tank (301) and the drain tank (302) is withdrawn, the other of the water supply tank (301) and the drain tank (202) may be prevented from being withdrawn arbitrarily.

[0263] The clothing treatment device of the present invention may further include a drainage unit (330) that collects water condensed in the circulation duct (320) into a drainage tank (302).

[0264] The above drainage unit (330) may include a drainage pump (331) that receives water from the guide pipe (3263) and a drainage hose (333) that receives water from the drainage pump (331) and guides it to a drainage tank (301).

[0265] The drainage unit (330) of the present invention may further include a discharge pipe (334) that connects the drain hose (333) and the drain tank (301). The discharge pipe (334) may be provided to receive water from the drain hose (333) and guide it into the drain tank (302).

[0266] Meanwhile, the discharge pipe (334) may be directly connected to the drain hose (333) or may be provided as an integral part with the drain hose (333).

[0267] However, the clothing treatment device of the present invention can install the discharge pipe (334) in the circulation duct (320) so that water can be continuously supplied even when the water level inside the drain tank (302) reaches full, and the circulation duct (320) can be provided so that water flowing back from the discharge pipe (334) or the drain tank (301) can be received back inside.

[0268] In this way, the circulation duct (320) and the reservoir (326) can temporarily function as a drainage tank (302) to expand the reservoir capacity. As a result, water can be prevented from overflowing outside the drainage tank (302).

[0269] For example, the detachable portion (380) may include a detachable communication portion (384) that is provided to penetrate the detachable support portion (382) so as to allow the drain hose (333) and the drain pipe (302) to communicate with each other.

[0270] The above-mentioned detachable connection part (384) can be formed in an area facing the supply hole provided in the drain pipe (301) when the drain pipe (301) is installed on the load-bearing part (381).

[0271] The above discharge pipe (334) may be provided by extending from the circulation duct (320) or may be provided by extending from the detachable portion (380). The discharge pipe (334) may be provided as an injection molded product. Accordingly, the discharge pipe (334) can stably fix the end of the drain hose (333) and prevent the drain hose (333) from being bent abruptly.

[0272] In addition, the discharge pipe (334) is provided as a pipe-shaped injection molded product that is fixed to the circulation duct (320) or the support (380), so that the installation position can always be fixed. Accordingly, the end of the discharge pipe (334) and the supply hole provided in the drain tank (302) are always positioned in the correct position, so that the condensate supplied from the drain pump (331) can stably flow into the drain tank (302).

[0273] The clothing treatment device of the present invention may further include a backflow unit (335) that allows water contained inside the drain (302) to flow back into the circulation duct (320) or the residual water treatment unit (330).

[0274] The above-mentioned backflow portion (335) may be provided at the lower portion of the discharge pipe (334) and may be provided to communicate between the circulation duct (320) and the inside of the drainage tank (302). The above-mentioned backflow portion (335) may be provided to guide water inside the drainage tank (302) into the inside of the circulation duct (320).

[0275] Figure 12 illustrates in detail the structure of the reflux section of the clothing treatment device of the present invention.

[0276] The above circulation duct (320) may have the evaporator (341) and the condenser (343) arranged inside it. At this time, the evaporator (341) may be arranged in front of the condenser (343) in the circulation duct (320).

[0277] The above-mentioned reflux unit (335) may be arranged in front of the circulation duct (320). At this time, if water flowing into the circulation duct (320) from the reflux unit (335) comes into contact with the evaporator (341), the evaporator (341) may be unnecessarily corroded or contaminated, and the efficiency of the evaporator (341) in cooling air may be reduced.

[0278] Accordingly, so that the water supplied from the reflux unit (335) does not contact the evaporator (341) along the air flowing toward the evaporator (341), the evaporator (341) may be placed closer to the rear of the circulation duct (320) than the reflux unit (335).

[0279] The above-mentioned backflow portion (335) or the discharge pipe (334) may be exposed to the front of the circulation duct (320) by penetrating the detachable connection portion (384). When the drain pipe (302) is seated on the detachable support portion (382), the end of the backflow portion (335) or the discharge pipe (334) may be inserted into the drain pipe (302).

[0280] As a result, water discharged outside the circulation duct (320) through the drain pump (331) can be collected in the drain tank (302) along the drain hose (333) and the discharge pipe (334).

[0281] When the water level of the above drain (302) reaches the discharge pipe (334) or the backflow portion (335), water overflowing from the backflow portion (335) flows back into the circulation duct (320) along the backflow portion (335), thereby preventing water from leaking outside the machine room (300).

[0282] The above guide channel (338) may be provided to extend along the width direction of the front surface of the circulation duct (320). One end of the guide channel (338) may be arranged to communicate with the reflux view (335), and the other end may be arranged on the upper portion of the reservoir (326).

[0283] In addition, the circulation duct (320) may further include a blocking wall (337) that guides water flowing in from the reflux view (335) to the guide path (338).

[0284] Figure 13 illustrates the lower configuration of the bottom surface of the inner case.

[0285] The above-mentioned bottom surface (230) can introduce air inside the inner case (200) into the circulation duct (320) through the inlet hole (232), and can receive dehumidified and heated air while passing through the circulation duct (320) through the discharge hole (231). In addition, steam supplied from the steam supply unit (800) can be supplied through the steam hole (233).

[0286] However, the bottom surface (230) can block air, moisture, and foreign substances inside the inner case (200) from leaking into the machine room (300) except for the through holes.

[0287] A detachable part (380) is provided in front of the machine room (300) to prevent external air, moisture, or foreign substances from entering the machine room (300).

[0288] The garment treatment device of the present invention can install the ironing module (S) in the machine room (300). This can prevent the ironing module (S) from being exposed to air, moisture, and foreign substances inside the inner case (200).

[0289] In addition, the machine room (300) is positioned lower than the floor surface (230) in its entirety, so that it can be positioned and installed independently from the inner case (200). As a result, the machine room (300) can be manufactured as a module and installed in the cabinet (100).

[0290] The above ironing module (S) can be installed in a modular manner in the machine room (300). Therefore, the ironing module (S) can also be selectively installed in the machine room (300) without affecting the internal configuration of the machine room (300) and the cabinet (100).

[0291] Accordingly, even if the garment treatment device of the present invention is a product that does not have the ironing module (S), the ironing module (S) can be installed in the machine room (300) at a later date.

[0292] The above ironing module (S) may be arranged to one side of the two sides of the machine room (300). The ironing module (S) may minimize interference with existing components such as the circulation duct (320).

[0293] The above ironing module (S) may further include a storage module (1000) capable of storing the steam iron (1300) that supplies at least one of heat and steam to the clothing inside a machine room (300), and a heating module (2000) that includes the heating unit (2100) that generates at least one of heat and steam supplied to the steam iron (1300).

[0294] The heating module (2000) may be positioned at the rear of the storage module (1000), and the storage module (1000) may be exposed at the front of the machine room (300). Accordingly, the steam iron (1300) may be provided so that it can be pulled out to the front of the machine room (300) and accessible to clothing.

[0295] The above-mentioned detachable portion (380) may have a pass-through surface that supports the steam iron (1300) so that it can be pulled out and inserted forward within the machine room (300).

[0296] The above ironing module (S) may further include a base module (3000) that supports the storage module (1000) and the heating module (2000). The base module (3000) provides a space in which the storage module (1000) and the heating module (2000) are installed, and may be provided to fix the position and connection state of the storage module (1000) and the heating module (2000).

[0297] In addition, the base module (3000) may be provided to place the storage module (1000) and the heating module (2000) at a predetermined height or higher than the bottom surface of the base (310) or cabinet.

[0298] Accordingly, water or residual water condensed in the storage module (1000) and the heating module (2000) can be automatically discharged by gravity, and the storage module (1000) and the heating module (2000) can be prevented from being damaged by vibration or impact.

[0299] The above storage module (1000) and the above heating module (2000) can be mounted on the base module (3000) and installed inside the machine room (300).

[0300] Of course, if the storage module (1000) and the heating module (2000) can be stably installed in the machine room (300), the base module (3000) may be omitted.

[0301] Figure 14 illustrates in detail the structure of the above iron module.

[0302] The above storage module (1000), the heating module (2000), and the base module (3000) may be manufactured as one unit, or may be manufactured separately and then combined and fixed to each other.

[0303] In the following description, the storage module (1000), the heating module (2000), and the base module (3000) are described as being provided as independent modules, but this does not exclude the possibility that they are provided as an integrated unit.

[0304] The storage module (1000), the heating module (2000), and the base module (3000) can be manufactured independently of each other and installed in the machine room (300). Accordingly, the storage module (1000), the heating module (2000), and the base module (3000), which are smaller in volume than the entire iron module (S), can be sequentially installed in the machine room (300), so that the work of installing the iron module (S) in the machine room (300) can be facilitated.

[0305] In addition, if any one of the storage module (1000), the heating module (2000), and the base module (3000) is damaged or defective, only a specific module needs to be replaced or repaired, so maintenance and repair of the iron module (S) can be easy.

[0306] The storage module (1000) may include a steam iron (1300) capable of approaching the garment and supplying at least one of heat and steam to the garment. The steam iron (1300) has a surface facing the garment made of a material capable of transmitting heat, and can remove wrinkles from the garment when in contact with the garment.

[0307] In addition, the steam iron (1300) is equipped with a spray hole through which steam is sprayed onto the surface facing the clothing, so that high-temperature steam is supplied to the surface of the clothing to not only remove wrinkles from the clothing, but also perform refreshing processes such as sterilization and deodorization of the clothing.

[0308] The above steam iron (1300) may be equipped to generate heat and steam by being supplied with its own power, but may also be equipped to receive and transmit at least one of heat and steam from the heating module (2000).

[0309] When the above steam iron (1300) is equipped to receive at least one of heat and steam, the weight and volume of the steam iron (1300) are reduced, so that a user can easily lift the iron to the surface of clothing placed on a stand or fixed part.

[0310] The above storage module (1000) may further include a storage section (1200) for accommodating the steam iron (1300). The storage section (1200) may be provided in the shape of a case having a storage space for storing the steam iron (1300) therein.

[0311] The storage unit (1200) above serves to store the steam iron (1300) inside the machine room (300), and the position at which the steam iron (1300) is stored inside the machine room (300) can be changed.

[0312] The width of the storage unit (1200) may be provided to be greater than the width of the steam iron (1300), and the length of the storage unit (1200) may be provided to be greater than the length of the steam iron (1300).

[0313] For example, the width of the storage unit (1200) may be provided to be approximately 1 to 3 cm larger than the width of the steam iron (1300). However, the width of the storage unit (1200) may not be provided to be more than 5 cm larger than the width of the steam iron (1300). This may prevent the steam iron (1300) from vibrating or moving left and right inside the storage unit (1200).

[0314] The storage unit (1200) may be provided such that the length in the front-back direction is longer than the width in the left-right direction, and the height in the up-down direction is longer than the width in the left-right direction. Accordingly, the steam iron (1300) may be stably inserted and stored within the storage unit (1200).

[0315] The above storage unit (1200) may include a storage body (1210) that accommodates the steam iron (1300), and an open surface (1220) provided at the front of the storage body (1210) through which the steam iron (1300) can be withdrawn.

[0316] The above storage body (1210) can accommodate the steam iron (1300) so as to block the steam iron (1300) from being exposed to the upper, both sides, and rear of the machine room.

[0317] The above storage body (1210) may be configured to receive and withdraw the steam iron (1300) only through the open surface (1220). As a result, the steam iron (1300) may be exposed only to the front of the machine room (300), and may be prevented from being exposed or withdrawn in other directions.

[0318] The above-mentioned open surface (1220) may be provided to open the entire front of the storage body (1210). If the stylus (1300) can be withdrawn and inserted, it may be provided to open only a portion of the front surface of the storage body (1210).

[0319] The above storage module (1000) may further include a drawer that is pulled out to the front of the storage section (1200) to expose the steam iron (1300).

[0320] In addition, as illustrated, the storage module (1000) may further include a cover door (1130) that is rotatable forward from the storage body (1210) or base module (3000) to open the open surface (1220).

[0321] An independent control unit (4000) that independently controls the iron module (S) and the refresh module (T) may be placed at the rear of the storage module (1000). The independent control unit (4000) will be described later.

[0322] The above heating module (2000) may include a heating unit (2100) that receives water from a water tank (301), supplies steam to the steam iron (1300), and also supplies steam to the inner case (200).

[0323] The above heating unit (2100) can receive power, heat water, generate steam, and then transmit the steam to the steam iron (1300) through the cable (1400).

[0324] For example, the heating unit (2100) may be equipped with a steam generating unit that receives electricity and water to generate steam.

[0325] In addition, the heating unit (2100) can supply steam to the steam iron (1300) through the valve unit (2800), the cable (1400), and the guide tube (1500), and can also supply steam to the inside of the inner case (200).

[0326] The above heating unit (2100) may include an outlet (2110) through which steam is discharged.

[0327] The above valve unit (2800) may be provided to open and close the outlet (2110) or to selectively open and close the steam discharged from the outlet (2110) from moving to the cable (1400) or guide tube (1500).

[0328] The valve part (2800) opening the guide tube (1500) may mean a series of states in which the guide tube (1500) is set to a state in which it is connected to the heating part (2100) and can receive steam, and the valve part (2800) closing the guide tube (1500) may mean a series of states in which the guide tube (1500) is set to a state in which it is blocked from communicating with the heating part (2100) and cannot receive steam.

[0329] For example, the valve unit (2800) may directly open and close the guide tube (1500), or may indirectly open and close the guide tube (1500) by opening and closing the outlet of the heating unit or a separate branch pipe, etc.

[0330] The valve part (2800) opening the cable (1400) may mean a series of states in which the cable (1400) is set to a state in which it is connected to the heating part (2100) and can receive steam, and the valve part (2800) closing the cable (1400) may mean a series of states in which the cable (1400) is set to a state in which it is blocked from communicating with the heating part (2100) and cannot receive steam.

[0331] For example, the valve unit (2800) may directly open and close the cable (1400), or may indirectly open and close the cable (1400) by opening and closing the outlet of the heating unit or a separate branch pipe, etc.

[0332] The above valve part (2800) may include a first valve part (2810) that determines whether to supply steam to the inner case (200), and a second valve part (2820) that determines whether to supply steam to the steam iron (1300).

[0333] The above guide tube (1500) and the above cable (1400) can be arranged completely separated from each other from one end to the other.

[0334] In addition, the first valve part (2810) and the second valve part (2820) may also be positioned completely separately. In this case, the first valve part (2810) may be directly coupled to the guide tube (1500) to open and close the guide tube (1500), and the second valve part (2820) may be directly coupled to the cable (1400) to directly open and close the cable (1400).

[0335] The above valve unit (2800) may be equipped with a solenoid valve and may be controlled by the main control unit (700) or the independent control unit (4000).

[0336] Regardless of where the valve part (2800) is coupled and placed, the valve part (2800) can be controlled to close the cable (1400) when the guide tube (1500) is opened, and to close the guide tube (1500) when the cable (1400) is opened.

[0337] The above valve unit (2800) can be controlled to prevent the cable (1400) and the guide tube (1500) from communicating with the heating unit (2100) at the same time. That is, the valve unit (2800) can be controlled to open only one of the cable (1400) and the guide tube (1500) to supply steam.

[0338] In this way, steam can be supplied intensively to only one of the cable (1400) and the guide tube (1500), thereby securing the minimum amount of steam required for processing clothes.

[0339] The heating unit (2100) may be configured in any manner as long as it can receive water and heat steam. The heating unit (2100) may include a receiving body (2110) forming an outer appearance and a heater provided inside the steam container to heat water.

[0340] In addition, the heating module (2000) may further include a water pump (2200) that supplies water stored in the water tank (301) to the heating unit (2100).

[0341] The above-mentioned water supply pump (2200) can supply water to the heating unit (2100) at a pressure higher than atmospheric pressure. Accordingly, the heating unit (2100) can generate steam while receiving water even when the internal pressure is formed higher than atmospheric pressure.

[0342] Unlike the storage module (1000), the heating module (2000) can be prevented from being withdrawn from the machine room (300). That is, when the heating module (2000) is installed in the machine room (300), it can be fixed inside the machine room (300). For example, the heating unit (2100) can be mounted and fixed to the base module (3000).

[0343] The heating module (2000) may be positioned rearward relative to the storage module (1000) in its entirety. This prevents the storage module (1000) from being exposed to the front of the machine room (300) and the steam iron (1300) from being drawn in and out of the front of the machine room. In addition, the storage module (1000) may be prevented from being exposed to the rear of the machine room (300).

[0344] The heating module (2000) may be mounted and fixed to the base module (3000) or the base portion (310). In order for the entire configuration of the heating module (2000) to be stably installed, the heating module (2000) may be entirely accommodated in a heating case (2700). The heating case (2700) may have an opening at the front through which the cable (1400) may pass, and may be provided in a box shape in which both sides and the upper surface are not exposed to the outside.

[0345] Most of the components of the heating module (2000) can be installed inside the heating case (2700). Therefore, maintenance and repair of the heating module (2000) can be easy.

[0346] The above base module (3000) may include a base panel (3200) provided parallel to the base portion (310), and a mounting panel (3100) extending from the base panel (3200) and on which the storage module (1000) and the heating module (2000) are mounted.

[0347] The above base panel (3200) may be provided integrally with the base portion (310).

[0348] However, if the ironing module (S) is provided as an independent module from the circulation duct (320), the base panel (3200) may be provided separately from the base part (310).

[0349] The above fixing panel (3100) may be provided to fix the lower portion of the storage module (1000) and the heating module (2000), but to allow the storage module (1000) and the heating module (2000) to be spaced apart from the base panel (3200) by a certain height.

[0350] As a result, a space can be secured between the storage module (1000) and the heating module (2000) and the base panel (3200) in which a water supply structure connected to the cable (1400) or the heating module (2000) to supply water to the heating module (2000) and a drainage structure (2600) to discharge water from the heating module (2000) can be installed.

[0351] Furthermore, because the storage module (1000) and the heating module (2000) are positioned above the drainage structure (2600) due to the fixing panel (3100), condensate or residual water formed in the storage module (1000) and the heating module (2000) can be guided to the drainage structure without a separate power unit.

[0352] The above-mentioned fixing panel (3100) may be provided to extend upward from both sides of the base panel (3200).

[0353] The above base module (3000) can be coupled to the inner surface of the above mounting panel (3100) and a rail (3300) for pulling out the above withdrawal portion (1110) can be coupled thereto.

[0354] Figure 15 illustrates the water supply and drainage structure of the heating module (2000).

[0355] In order for the above heating unit (2100) to generate steam and deliver it to at least one of the steam iron (1300) and the inner case (200), it is necessary to supply water.

[0356] The above water supply pump (2200) may be connected to the water supply tank (301) and may be provided to supply water from the water supply tank (301).

[0357] Of course, the above water supply pump (2200) can supply water to the heating unit (2100) through a separate water supply source other than the above water tank.

[0358] Meanwhile, the above water supply pump (2200) can supply water while increasing the pressure inside the heating unit (2100), rather than simply supplying water to the heating unit (2100).

[0359] The above heating unit (2100) may be equipped with a pressure sensor (2300) that measures internal pressure.

[0360] The above valve part (2800) can be controlled to open and close depending on the pressure inside the heating part (2100).

[0361] The above heating unit (2100) may have only one outlet (2120) through which steam is discharged. The branch pipe (2900) is connected to the outlet (2120), and the branch pipe (2900) may have multiple outlets to transmit steam to the guide pipe (1500) and the cable (1400).

[0362] The above guide tube (1500) and the above cable (1400) may be respectively connected and fixed to the branch tube (2900).

[0363] The above first valve part (2810) and the above second valve part (2820) may be connected to a branch pipe (2900) that communicates with the guide pipe (1500) and may be provided so as to be in communication with each other.

[0364] The first valve part (891) and the second valve part (892) may be provided to selectively open and close the branch pipe (2900).

[0365] For example, the first valve part (2810) may be coupled to the branch pipe (2900) to selectively connect the branch pipe (2900) and the guide pipe (1500) to open and close the guide pipe (1500), and the second valve part (2820) may be coupled to the branch pipe (2900) to selectively connect the branch pipe (2900) and the cable (1400) to open and close the cable (1400).

[0366] The pressure sensor (2300) can be connected to an outlet (2120) extending from the above-mentioned receiving body (2110), and a valve unit (2800) for opening and closing the outlet (2120) can be coupled thereto.

[0367] The above valve unit (2800) can be controlled by the independent control unit (4000) of the iron module (S) or the main control unit (700) of the refresh module (T). The opening and closing of the valve unit (2800) can be controlled according to the pressure and temperature inside the receiving body (2110) or the pressure and temperature of the outlet (2120).

[0368] The above heating unit (2100) may be connected to both the steam iron (1300) and the inner case (200) to supply steam.

[0369] The above guide tube (1500) and the cable (1400) may be provided in any configuration as long as they can guide the steam supplied from the heating unit (800) to the end. For example, the guide tube (1500) and the cable (1400) may be provided in a pipe shape, or may be provided with a flexible material such as a hose.

[0370] The above cable (1400) may have one end connected to the branch pipe (2900) or the valve portion (2800), and the other end connected to the steam iron (1300). In addition, the guide pipe (1500) connected to the inner case (200) may have one end connected to the branch pipe (2900) or the valve portion (2800), and the other end connected to the steam nozzle (900) or the steam hole (233) of the inner case (200).

[0371] Of course, the garment treatment device of the present invention may omit the configuration of the steam nozzle (900) and be provided so that the guide tube (1500) directly communicates with the steam hole (233).

[0372] The above pressure sensor (2300) may be placed upstream of the valve unit (2800). Accordingly, the valve unit (2800) may be controlled to determine whether to open or close depending on the pressure detected by the pressure sensor.

[0373] Accordingly, the main control unit (700) can control the valve unit (2800) to open and close the guide tube (1500) and cable (1400) according to the pressure detected by the steam sensor (860).

[0374] Meanwhile, the pressure sensor (2300) may be fixedly connected to the branch pipe (2900). That is, the pressure sensor (2300) may be installed anywhere as long as it can detect the pressure of the steam upstream of the valve unit (2800).

[0375] The main control unit (700) or independent control unit (4000) can control the valve unit (2800) to open when the pressure inside the heating unit (2100) is higher than atmospheric pressure through the pressure sensor (2300). As a result, high pressure and a large amount of steam can be supplied to the inner case (200) and the steam iron (1300).

[0376] As a result, the time required to spray steam during the refreshing process or to remove wrinkles from clothing can be saved, and the time required for the heating unit (2100) to operate can be shortened. In addition, the performance of deodorizing and wrinkle removal from clothing can be further improved.

[0377] The garment treatment device of the present invention can supply high-pressure steam to the inner case (200) and the steam iron (1300) through the control of the valve unit (2800). Furthermore, the garment treatment device of the present invention can set the pressure of the steam supplied to the inner case (200) and the steam iron (1300) differently.

[0378] For example, the heating unit (2100) can supply steam to the steam iron through the valve unit (2800) at a pressure higher than the pressure of steam supplied to the inner case.

[0379] Accordingly, even if the cable (1400) is longer than the guide tube (1300), steam can be sufficiently transmitted to the steam iron (1300), and steam with stronger pressure can be sprayed onto the surface of the clothing, so that wrinkles on the clothing can be more reliably removed.

[0380] For example, the valve unit (2800) may be controlled to allow the supply of steam to the steam iron when the pressure of the steam generated in the heating unit (2100) is higher than a set value and to block the supply of steam to the inner case.

[0381] Conversely, the valve unit (2800) can be controlled to block the supply of steam to the steam iron and supply steam to the inner case when the pressure of the heating unit (2100) or the pressure of the steam is below a set value.

[0382] That is, when the pressure of the heating unit (2100) is equal to or higher than the set value, the first valve unit (2810) is controlled to close the guide tube (1500), and the second valve unit (2820) can be controlled to open the cable (1400). Conversely, when the pressure of the heating unit (2100) is equal to or lower than the set value, the first valve unit (2810) can open the guide tube (1500) according to the refresh cycle, but the second valve unit (2820) can be fundamentally blocked from opening the cable (1400). The set value may correspond to a pressure that is two to three times higher than the atmospheric pressure.

[0383] As a result, even if the heating unit (2100) is provided in one unit, steam of different pressures can be supplied to the inner case (200) and the steam iron (1300) through the valve unit (2800).

[0384] The pressure sensor (2300) may induce the water supply pump (2200) to operate more when the pressure of the heating unit (2100) is lower than the reference pressure, and may induce water or steam to be drained from the inside of the heating unit (2100) when the pressure of the heating unit (2100) is higher than the reference pressure. For example, the reference pressure may be set to be 1 bar to 3 bar higher than the atmospheric pressure.

[0385] The heating module (2000) may further include a water supply structure (2500) that supplies water to the heating unit (2100). Specifically, the water supply structure (2500) may include a path for supplying water to the water supply pump (2200) and a path for supplying water supplied to the water supply pump (2200) to the heating unit (2100).

[0386] The above heating unit (2100) can be mounted on the base module (3000) and fixed using a fastening member, etc., and the above water supply pump (2200) can also be mounted on the base module (3000).

[0387] The above heating module (2000) may include a pump connection pipe (2540) that connects the water supply pump (2200) and the heating unit (2100). The pump connection pipe (2540) is made of a flexible material such as a rubber hose and can guide high-pressure water into the interior of the heating unit (2100).

[0388] The above water supply structure (2500) may include a supply pipe (2530) that supplies the water from the water supply pump (2200) to the heating unit (2100). The water supply pump (2200) is connected to a device connection pipe (2520) that is also connected to a drainage device (2400), and the supply pipe (2530) may be provided to connect the heating unit (2100) to the device connection pipe (2520).

[0389] Meanwhile, the heating module (2000) may include a drainage device (2400) that discharges water inside the heating unit (2100) when the heating unit (2100) stops operating or when steam generated in the heating unit (2100) condenses to form water.

[0390] The above drainage device (2400) may be equipped with a pump or a simple valve. The drainage device (2400) may be positioned lower than the heating unit (2100) and may be equipped to receive water from the drain port (216) of the heating unit (2100).

[0391] The above drainage device (2400) can be connected to both the water supply structure (2500) and the drainage structure (2600). As a result, the structure for supplying or discharging water to the heating unit (2100) is unified, simplifying the flow path and saving space.

[0392] In this case, water supplied to the device connection pipe (2520) can be delivered to the drainage device (2400), and the drainage connection pipe (2610) can be provided to communicate with the device connection pipe (2520).

[0393] The above drainage device (2400) can be controlled to selectively open at least one of the drainage connection pipe (2610) and the device connection pipe (2520). When the drainage device (2400) locks at least one of the drainage connection pipe (2610) and the device connection pipe (2520), water supplied from the pump connection pipe (2540) can pass through the device connection pipe (2520) and be supplied to the sting generating unit (2100).

[0394] When the above drainage device (2400) opens both the drainage connection pipe (2610) and the device connection pipe (2520), water collected or condensed in the heating unit (2100) can be completely discharged through the drainage connection pipe (2610). Accordingly, the device connection pipe (2520) can perform the role of both a conduit for supplying water to the heating unit (2100) and a conduit for discharging water from the heating unit (2100).

[0395] The above drainage device (2400) can be controlled by an independent control unit described later.

[0396] Figure 16 illustrates another embodiment of the heating unit of the present invention.

[0397] The above heating unit (2100) may be provided with a cylindrical pressure case as a receiving body (2110) and may be provided with two outlets (2120).

[0398] That is, the above-mentioned receiving body (2110) may be provided as a one-piece metal case capable of withstanding a pressure of steam that is two to three times higher than atmospheric pressure.

[0399] In addition, the heating unit (2100) may have two outlets through which steam is discharged. For example, the heating unit (2100) may include a first outlet (2121) through which steam is discharged from the receiving body (2110), and a second outlet (2122) spaced apart from the first outlet (2121) through which steam is discharged from the receiving body (2110).

[0400] Accordingly, the heating unit (2100) of the present invention can omit the branch pipe (2900).

[0401] The first outlet (2121) can be connected to the guide tube (1500), and the second outlet (2122) can be connected to the cable (1400).

[0402] The first valve part (2810) may be coupled to the first outlet (2121) to open and close the guide tube (1500), and the second valve part (2820) may be coupled to the second outlet (2122) to open and close the cable (1400).

[0403] The first valve part (2810) and the second valve part (2820) may be arranged to be spaced apart from each other by the same distance as the first outlet (2121) and the second outlet (2122).

[0404] Accordingly, even if the positions of the steam iron (1300) and the steam holes of the inner case (200) are arranged at different angles with respect to the heating unit (800), the first outlet (2121) and the second outlet (2122) can be spaced apart, thereby preventing the guide tube (1500) or cable (1400) from interfering with each other or being excessively bent.

[0405] The control of the above valve unit (2800) may be the same as in the above-described embodiment.

[0406] Figure 17 illustrates a structure in which the above water supply structure and the above water supply unit are connected.

[0407] Hereinafter, the description is based on the heating unit (2100) having one outlet, but this is only an example, and the description can be made in the same way when the heating unit (2100) has multiple outlets, excluding the branch pipe configuration.

[0408] The above ironing module (S) is installed independently from the refresh module (T), but may be installed to communicate with the heating unit (2100) provided in the machine room (300). As a result, the ironing module (S) can be supplied with steam generated from water stored in the water tank (301).

[0409] Accordingly, the above ironing module (S) may be omitted from being connected to a separate water source or from having an additional water tank.

[0410] In addition, the garment treatment device of the present invention can supply steam to both the inside of the inner case (200) and the steam iron (1300) through one water tank (301).

[0411] When the water stored in the water tank (301) is driven by the water supply pump (2200), the water can pass through the water supply pump (2200) via the supply pipe (882) and be supplied to the heating unit (2100) via the water supply connection pipe (2510).

[0412] When the water supplied to the above heating unit (2100) is heated, steam can be generated, and the steam can be discharged through the outlet (2120).

[0413] The above valve unit (2900) can selectively open the outlet (2120), selectively open the branch pipe (2900), or selectively open the guide pipe (1500) and the cable (1400) to selectively move the steam from the heating unit (2100) to the outside.

[0414] If the valve part (2800) above opens the guide tube (1500), the steam passing through the guide tube (1500) can be discharged into the steam hole of the inner case (200), or, if the steam nozzle (900) is provided, can be discharged into the steam hole through the steam nozzle (900).

[0415] If the valve part (2800) above opens the cable (1400), the steam passing through the cable (1400) can move to the steam iron (1300) and be discharged.

[0416] Meanwhile, the clothing treatment device of the present invention can control only one of the refresh module (T) and the ironing module (S) to operate. When the door is closed, not only is the ironing module (S) unable to operate, but it is also intended to prevent excessive power consumption.

[0417] When the closing of the above door or one or more of the above refresh module (T) operations occur, the second valve unit (2820) can be controlled to close the cable (1400) so that steam is not supplied to the cable (1400).

[0418] When one or more of the above-mentioned door opening and the above-mentioned refresh module (T) termination occurs, the first valve unit (2810) can be controlled to close the cable (1300) so that steam is not supplied to the guide pipe (1300).

[0419] The above branch pipe (2900) may include a main body pipe (2910) that provides a space for steam to move, an inlet (2920) that connects the main body pipe (2910) and the outlet (2120), a first outlet (2930) that connects the main body pipe (2910) and the guide pipe (1500), and a second outlet (2940) that connects the main body pipe (2910) and the cable (1400).

[0420] The above main body (2910) may be provided in a pipe shape and may be provided with a material having strong rigidity so that the valve part (2800) can be fixed.

[0421] The first valve part (2810) may be coupled to the first discharge part (2930) to open and close the first discharge part (2920). Thus, the first valve part (2810) may be controlled to selectively allow the guide tube (1500) to communicate with the heating part (2100).

[0422] In addition, the second valve unit (2820) may be coupled to the second outlet (2940) to open and close the second outlet (2940). Accordingly, the second valve unit (2820) can be controlled to selectively allow the cable (1400) to communicate with the heating unit (2100).

[0423] As a result, when steam is generated in the heating unit (2100), it may flow into the main body pipe (2910), but when the valve unit (2800) closes the outlets of the branch pipe (2900), the steam may be blocked from being supplied to the inner case (200) and the steam iron (1300).

[0424] The above drainage structure (2600) may be provided to discharge water condensed in the steam generator (2100) or collected in the drainage device (2400).

[0425] The above water supply structure (2500) may further include a water supply connection pipe (2510) that supplies water from the water supply tank (301) to the heating unit (2100) or the water supply pump (2200).

[0426] The above drainage structure (2600) may include an inlet pipe (2620) that guides water discharged from the drainage device (2400) to a drain tank (302).

[0427] The above ironing module (S) may be provided to receive water from a water tank (301). Accordingly, the ironing module (S) may be omitted from being connected to a separate water source or from having an additional water tank. In addition, the garment treatment device may supply steam to both the inner case (200) and the steam iron (1300) through a single water tank (301).

[0428] Figure 18 illustrates a pre-existing structure that allows the above drainage structure and the above drainage section to communicate with each other.

[0429] The above circulation duct (320) may further include an inlet pipe (3264) that guides water discharged from the drainage structure (2600) to the reservoir (260).

[0430] The direction in which the above inlet pipe (3264) is provided and the direction in which the above guide pipe (3263) is provided may be different from each other.

[0431] For example, the guide tube (3263) may be formed on the front surface of the circulation duct (320), and the inlet tube (3264) may be formed on the left or right surface of the circulation duct (320).

[0432] The above inlet pipe (3264) may be provided in an area corresponding to the side of the reservoir (326) among the side surfaces of the above circulation duct (320).

[0433] The above inlet pipe (3264) is provided to communicate between the inside of the reservoir (326) and the outside of the circulation duct (320), and may be provided to protrude to the outside from the side of the circulation duct (320).

[0434] The above inlet pipe (3264) can be installed at a higher position than the bottom surface of the reservoir (326) or the guide pipe (3263).

[0435] When the above drainage structure (2600) discharges water into the inlet pipe (3264), the water is collected in the reservoir (326) and discharged into the guide pipe (3263) so that it can communicate with the drainage unit (330).

[0436] In this way, a separate drain for the ironing module (S) can be omitted.

[0437] Figure 19 illustrates a structure in which the above drainage structure and the above drainage section are connected.

[0438] The above ironing module (S) is installed separately and independently from the structure of the machine room (300), but can communicate with the drainage unit (330) of the refresh module (T) through the circulation duct (320).

[0439] As a result, the ironing module (S) may be provided to discharge residual water into a drain (302). Accordingly, the ironing module (S) may be provided with an additional drain (302) or may be provided with a structure that is connected to a separate drain.

[0440] The garment treatment device of the present invention can collect both the residual water collected in the circulation duct (320) and the residual water collected in the ironing module (S) into a single drainage tank (302). By discarding the water in the drainage tank (302), the user can discharge all the water collected in the circulation duct (320) and the ironing module (S).

[0441] The above drainage structure (2600) may be provided to communicate with the drainage unit (330) through the circulation duct (320).

[0442] The above drainage structure (2600) may include a drainage connection pipe (2610) connected to a drainage device (2400), and an inlet pipe (2620) connected from the drainage connection pipe (2610) and communicating with the drainage unit (330). The inlet pipe (2620) may be connected to the inlet pipe (3264).

[0443] The water and residual water condensed in the heating unit (2100) can be collected in the drainage device (2400). (Direction II) The water condensed in the steam iron (1300) can move along the cable (1400) and be collected in the drainage device (2400) through the heating unit (2100). (Direction I) The water collected in the drainage device (2400) can be connected to the inlet pipe (3264) along the inlet pipe (2620). It can be collected in the drain tank (302). (Direction III) That is, when the drainage pump (331) is driven, the water collected in the drainage device (2400) by negative pressure can be collected in the drain tank (302).

[0444] The above injection pipe (2620) may be provided to communicate with the inside of the circulation duct (320).

[0445] Accordingly, all of the water collected in the drainage device (2400) can be collected inside the circulation duct (320) and then moved to the drainage pump (331) through the guide pipe (3263). Even if the amount of water collected in the drainage device (2400) is large or the amount of water discharged through the drainage device (2400) is large, the water can be collected inside the circulation duct (320), thereby preventing the water from overflowing outside the machine room (300).

[0446] Meanwhile, the drainage device (2400) may be mounted on the base module (3000) and positioned higher than the end of the inlet pipe (2620). Accordingly, even if the drainage device (2400) does not generate any special power, the water collected in the drainage device (2400) may be collected in the reservoir (326) along the inlet pipe (2620).

[0447] When the above drain pump (331) is driven, the water collected in the reservoir (326) can be stored in the drain tank (302).

[0448] Figure 20 illustrates the structure and layout of the iron module and control unit.

[0449] The above main control unit (700) may be equipped to be connected to an external power source and to receive power.

[0450] The above main control unit (700) may be equipped to supply power to the refresh module (T) including the heat supply unit (340), the heating unit (2100), the water supply unit (2500), the drain unit (2600), and the blower unit (350), as well as to supply power to all electrical components of the clothing treatment device (1).

[0451] Meanwhile, the above iron module (S) must also supply power to the steam iron (1300).

[0452] For this purpose, the main control unit (700) may be equipped to supply power to the iron module (S).

[0453] In addition, the steam iron (1300) needs to have the amount of steam sprayed, the pressure of the steam, and the temperature of the steam controlled by the user's operation.

[0454] In this case, if the main control unit (700) is provided to supply power to the iron module (S) or control the iron module (S), there is a concern that the size of the main control unit (700) may be larger than the area of ​​the circulation duct (320), and there is a concern that the main control unit (700) may not be compatible with a clothing treatment device that does not have an iron module (S).

[0455] Accordingly, the iron module (S) may further include an independent control unit (4000) capable of supplying power to the steam iron (1300) or controlling the steam iron (1300).

[0456] Meanwhile, the above steam iron (1300) may be provided as a separate configuration from the independent control unit (4000).

[0457] If the independent control unit (4000) is placed inside the steam iron (1300), the steam iron (1300) may become too large for the user to hold, and the weight of the steam iron (1300) may also make it impossible for the user to hold it.

[0458] Therefore, the iron module (S) of the present invention can fix the independent control unit (4000) to the storage unit (1200) without installing the independent control unit (4000) to the steam iron (1300).

[0459] As a result, the steam iron (1300) can be equipped with a simple configuration that only includes an ON / OFF switch or a steam injection switch.

[0460] The above independent control unit (4000) may be connected to the main control unit (700) via a wire without being directly connected to an external power source, and may be provided to receive the necessary power from the main control unit (700). In this case, the main control unit (700) may serve as an external power source for the iron module (S).

[0461] Accordingly, the clothing treatment device of the present invention may further include a control line (L1) electrically connecting the independent control unit (4000) and the main control unit (700).

[0462] The independent control unit (4000) can receive various types of information from the main control unit (700) via the control line (L1). The independent control unit (4000) can receive information about whether the door (120) that can be recognized by the main control unit (700) has closed the opening (220) and information about whether the refresh module (T) is operating, and control the iron module (S).

[0463] The above ironing module (S) can operate regardless of the control state of the refresh module (T) due to the independent control unit (4000). However, the ironing module (S) is provided to operate only when the door (120) is opened, and the heat supply unit (340) and the heating unit (800) must be controlled to operate on the premise that the door (120) is not opened. To this end, the independent control unit (4000) is provided to receive power from the main control unit (700) through the control line (L2) and to communicate with the main control unit (700), thereby recognizing the opening state of the door (120) and the operating states of the heat supply unit (340) and the heating unit (800) to control the ironing module (S).

[0464] Meanwhile, the steam iron (1300) may be equipped with a heater that receives power through an independent control unit (4000) and further heats the condensed water inside. Since the heater is provided separately from the independent control unit (4000), its capacity may be reduced, and the steam iron (1300) may be maintained in a compact size.

[0465] Although not shown, the control line extending from the independent control unit (4000) may be inserted into or built into the cable (1400) and extended to the steam iron (1300).

[0466] Figure 21 illustrates an additional embodiment of the storage module.

[0467] The storage unit (1200) of the present invention may include a storage body (1210) for storing the steam iron (1300) inside the machine room, and a cover door (1130) that is rotatably provided at the front of the storage body (1210) or at the detachable part (380) to shield the inside of the storage body (1210).

[0468] The above storage unit (1200) may include an open surface (1220) provided in front of the storage body (1210) through which the steam iron (1300) can be withdrawn.

[0469] The above cover door (1130) can expose the steam iron (1300) accommodated in the storage body (1210) by simply rotating. As a result, a structure such as a drawer for pulling the steam iron (1300) forward from the storage unit (1200) can be omitted.

[0470] The cover door (1130) may be provided with an area capable of shielding the open surface (1220) or the through hole of the detachable portion (380). When the cover door (1130) shields the open surface (1220) or the through hole, it may be arranged parallel to the water tank (301).

[0471] The above cover door (1130) may be provided with a lower portion that can be rotated to a detachable portion (380) and an upper portion that can be moved away from the housing (1200).

[0472] Accordingly, when the door (120) is closed, the cover door (1130) can automatically close the open surface (1220) of the housing.

[0473] The storage unit (1200) may further include an iron mounting portion (1190) that supports the steam iron (1300) at the lower portion of the housing (1200). The iron mounting portion (1190) may be provided so that the head portion of the steam iron (1300) is detachable.

[0474] The above-mentioned iron mounting portion (1190) may include a mounting body (1191) mounted on the storage body (1210), and a mounting groove (1192) sunken into the upper surface of the mounting body (1191) to which the head of the steam iron (1300) is mounted.

[0475] The above ironing mounting portion (1190) can be accommodated in the storage body (1210) without being pulled out to the open surface (1220).

[0476] Figure 22 illustrates a steam iron housed in the housing body.

[0477] The above storage body (1210) may include a first body (1211) mounted on the support panel (3200), and a second body (1222) coupled to the upper portion of the first body (1211) to provide a space for storing the steam iron (1300) therein.

[0478] The front of the first body (1211) can form the lower part of the open surface (1220), and the front of the second body (1212) can form the upper part of the open surface (1220).

[0479] The iron mounting portion (1190) that supports the steam iron (1300) may be installed inside the storage body (1210).

[0480] The above support panel (3200) may further include a hinge portion (3400) to which the cover door (1130) is rotatably coupled at the front.

[0481] The above hinge portion (3400) can be placed in front of the iron mounting portion (1190) and the open surface (1220).

[0482] The above hinge portion (3400) may be provided so that the lower end of the cover (1130) can be positioned at a height below the through hole (385). Accordingly, the cover door (1130) may be provided to selectively block or open the through hole (385).

[0483] The above cover door (1130) can expose the open surface (1220) by opening the through hole (385) and can expose the steam iron (1300).

[0484] The above cover (1130) can close the through hole (385) to prevent the open surface (1220) and the steam iron (1300) from being exposed to the outside.

[0485] Figure 23 illustrates how the steam iron is inserted and removed. (Translator's Note: Same as Figure 23.)

[0486] Referring to Fig. 23(a), the cover (1130) can be rotated forward to open the through hole (385). Accordingly, the steam iron (1300) can be pulled forward from the housing (1200) through the open surface (1220) and the through hole (385).

[0487] In addition, the steam iron (1300) can be pulled out to spray steam on the surface of clothing, then inserted into the through hole (385) again, and inserted into the open surface (1220) to be mounted on the iron mounting portion (1190) from the head portion (1310).

[0488] Referring to Fig. 23(b), a user can roll up the cable (1400) and insert it into the through hole (385). At this time, a portion of the cable (1400) is inserted into the storage body (1210), but the remaining portion can be placed between the open surface (1220) and the through hole (385).

[0489] Referring to Fig. 23(c), the cover (1130) can close the through hole (385). The steam iron (1300) has an iron cover (1350) that is mounted on the iron mounting portion (1190), and the handle portion (1311) can be supported on the back surface of the cover (1310).

[0490] Additionally, at least a portion of the cable (1400) may be supported on the back surface of the cover (1310).

[0491] Accordingly, the user can easily insert the steam iron (1300) and the cable (1400) into the through hole (385), and if the storage body (1210) accommodates only the iron cover (1350), it is sufficient to provide a space that accommodates only a portion of the steam iron (1300) and a portion of the cable (1400).

[0492] In other words, the space between the open surface (1220) and the through hole (385) can be utilized as a space for accommodating the steam iron (1300) and the cable (1400).

[0493] Accordingly, the overall length and volume of the ironing module (s) can be reduced.

[0494] Figure 24 illustrates an embodiment of a control method for supplying steam to a steam iron and an inner case using one heating unit.

[0495] The clothing treatment device of the present invention can supply steam to both the inner case (200) and the steam iron (1300) by heating one of the heating parts (2100).

[0496] In addition, the clothing treatment device of the present invention may be equipped to determine whether to supply steam to the inner case (200) and the steam iron (1300) through the valve unit (2800), even if steam is generated in the heating unit (2100).

[0497] To this end, the garment treatment device of the present invention can perform a mode check step (A1) for checking whether a command to operate the ironing module (S) has been input or the ironing module (S) has been activated, or a command to operate the refresh module (T) has been input or the refresh module (T) has been activated.

[0498] The above mode inspection step (A1) may correspond to detection through an operation command input to the main control unit (700) or independent control unit (4000).

[0499] Alternatively, the above mode check step (A1) may be determined by whether the door (120) is open or closed. That is, when the door (120) is open, only the damiri module (S) can be activated, and when the door (120) is closed, the ironing module (S) cannot be activated.

[0500] If it is determined that the refresh module (T) is operating in the above mode check step (A1), the first opening step (A2-1) of opening the first valve unit (2810) can be performed.

[0501] In this case, the second valve part (2820) is closed to prevent the steam from moving arbitrarily to the steam iron (1300).

[0502] In the first opening stage (A2-1), if the heating unit (800) is provided so that steam is immediately supplied to the inner case (200) when steam is generated and only steam corresponding to atmospheric pressure is provided to the inner case (200), the first valve unit (2810) will be maintained in an open state from the beginning, and thus, the first valve unit (2810) can correspond to being maintained in an open state.

[0503] In the first opening step (A2-1), the heating unit (800) may include a simple drive (A3-1) that simply drives the water until it is converted into steam. That is, the heating unit (2100) may simply heat the water until steam can be generated.

[0504] When the heating unit (2100) generates steam, the steam can pass through the first valve unit (2810) and be naturally sprayed into the inner case (200) along the guide tube (1500), in a steam spraying step (A6).

[0505] If the iron module (S) is determined to be operating in the above mode check step (A1), the second valve unit (2820) may be closed in a first closing step (A2-2). In this case, the first valve unit (2810) may also be closed, thereby preventing the steam from moving arbitrarily to the inner case (200).

[0506] The above heating unit (800) can perform a high-pressure driving step (A3-2) of heating the steam until the pressure becomes higher than atmospheric pressure. The pressure sensor (2300) can perform a pressure detection step (A4) of detecting that the pressure inside the heating unit (2100) corresponds to a set value, and the heating unit (2100) can maintain the high-pressure driving step (A3-3) until the pressure corresponds to the set value.

[0507] When the pressure inside the heating unit (2100) reaches the set value in the pressure sensing step (A4), a second opening step (A5) in which the second valve unit (2820) is opened can be performed.

[0508] In the second opening step (A5), the first valve part (2810) can be kept closed. As a result, the steam injection step (A6), in which the steam generated in the heating part (2100) is injected only to the steam iron (1300), can be performed.

[0509]

[0510] Figure 25 illustrates a control method for supplying steam to a steam iron and an inner case using one heating unit.

[0511] The clothing treatment device of the present invention may be provided with a single outlet (2120) of the heating unit (2100) and branched into a steam iron (1300) and an inner case (200) through a branch pipe (2900), and may be provided with a plurality of outlets (2120) and connected to the steam iron (1300) and the inner case (200) respectively, and may be provided with a plurality of valve units (2800).

[0512] The first valve part (2810) may be provided to open and close a guide pipe (1500) that supplies steam from the heating part (2100) to the inner case (200), and the second valve part (2820) may be provided to open and close a cable (1400) that supplies steam from the heating part (2100) to the steam iron (1300).

[0513] Meanwhile, the inner case (200) and the steam iron (1300) can physically supply steam simultaneously.

[0514] However, since the refresh process is performed when the door (120) seals the receiving space (220) of the inner case, it is preferable that steam be supplied to the inner case (200) only when the door (120) closes the cabinet (100).

[0515] In addition, since the steam iron (1300) is assumed to be withdrawn from the machine room (300), it is preferable that steam be supplied only when the door (120) opens the cabinet (100).

[0516] Accordingly, the garment treatment device of the present invention can control the valve unit (2800) so that only one of the guide tube (1500) and the cable (1400) is opened.

[0517] In addition, since the steam iron (1300) directly sprays steam and heat on the surface of clothing in an open space to remove wrinkles from clothing, and the inner case (200) steams clothing in a closed space, it is preferable that the pressure of the steam supplied to the steam iron (1300) be set higher than the pressure of the steam supplied inside the inner case (200), and it may be more advantageous for the pressure of the steam supplied inside the inner case (200) to be higher than the atmospheric pressure.

[0518] As a result, the garment treatment device of the present invention can set the control of the first valve unit (2810) and the second valve unit (2820) differently depending on whether the steam iron (1300) and the heat supply unit (340) are in operation, whether the door is open, and the pressure state of the steam generated in the heating unit (2100).

[0519] For example, before power is supplied to the garment treatment device of the present invention, or even if power is supplied, before the refresh cycle or the steam iron starts operating, the garment treatment device of the present invention can perform a closing step (S1) in which the valve unit (2800) is controlled to close all steam-related paths.

[0520] In the above closing step (S1), the first valve part (2810) can be controlled to close the guide tube (1500), and the second valve part (2820) can be controlled to close the cable (1400).

[0521] When the refresh cycle starts or a command to operate the steam iron is input, the garment treatment device of the present invention can perform a heating step (S2) of boiling water and generating steam by driving the heating unit (2100).

[0522] The above heating step (S2) can be performed during the process of performing the above closing step (S1). Therefore, in the heating step (s2), water, rather than steam, can be prevented from being supplied to the guide tube (1500) and the cable (1400), and even if steam is generated in the heating step (s2), it can be prevented from being supplied to the guide tube (1500) and the cable (1400).

[0523] The above heating step (s2) can be continuously operated until steam is generated in the heating unit (2100). The garment treatment device of the present invention can perform a detection step (s3) for detecting whether steam is generated in the heating unit (2100). The detection step (S3) can confirm whether steam is generated through a temperature sensor or pressure sensor (2300) coupled to the heating unit (2100).

[0524] When it is detected that steam is generated in the above heating unit (2100), the garment treatment device of the present invention can first determine at least one of whether the door (120) is open and whether the generated steam has reached a target value.

[0525] For example, the garment treatment device of the present invention can maintain the second valve unit (2820) in a closed state if the door is closed, and can maintain the first valve unit (2810) in a closed state if the door is open.

[0526] In addition, even when the door is closed, if the pressure of the steam does not reach the reference value, the first valve part (2810) can be maintained in a closed state, and even when the pressure of the steam reaches the reference value, the first valve part (2810) can be opened only when the steam injection stage is reached in the refresh cycle.

[0527] In addition, even when the door is open, if the pressure of the steam does not reach a set value higher than the reference value, the second valve part (2820) can be maintained in a closed state, and even if the pressure of the steam reaches the set value, the second valve part (2820) can be opened only when a spray button or the like on the steam iron (1300) is pressed.

[0528] For example, the clothing treatment device of the present invention can perform a judgment step (S4) of determining whether the door is open in the detection step (S3) or the driving step (S2).

[0529] If it is detected that the door is open in the above judgment step (S4), the garment treatment device of the present invention can perform a high pressure judgment step (S5-1) to determine whether the pressure of the heating unit (2100) has reached a set value (or maximum value) while keeping the first valve unit (2810) closed in any case.

[0530] In this case, the driving step (S2) can be continued until the pressure of the steam reaches the set value.

[0531] In the above high pressure determination step (s5-1), when the pressure of the steam reaches the set value, the garment treatment device of the present invention can perform a spraying step (S6-1) in which the second valve part (2820) is opened. In the spraying step (S6-1), steam can be sprayed at high pressure to the steam iron (1300), and the first valve part (2810) can remain closed.

[0532] If the door is detected to be closed in the above judgment step (S4), the garment treatment device of the present invention can perform a target judgment step (S5-2) of judging whether the pressure of the heating unit (2100) has reached a reference value (target value) while maintaining the second valve unit (2820) closed in any case.

[0533] In this case, the driving step (S2) can be continued until the pressure of the steam reaches the reference value.

[0534] In the above target judgment step (s5-2), when the pressure of the steam reaches the reference value, the garment treatment device of the present invention can perform a supply step (S6-2) in which the first valve part (2810) is opened. In the above supply step (S6-1), steam can be sprayed into the inner case (200), and the second valve part (2820) can remain closed.

[0535] The above reference value may be set higher than atmospheric pressure, and may be set to be more than 1 atm and less than 2 atm.

[0536] The above setting value can be set to 2 atm or more and less than 4 atm as described above.

[0537] In addition, whether the door is closed can be determined by a reed switch and magnet provided in the door (120) and cabinet (100).

[0538] The present invention may be implemented in various modified forms, and the scope of the invention 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.
