Description

Ironing module including a steam iron and a garment treatment device including the same

[0001] The present invention relates to a garment treatment device including an ironing module including a steam iron capable of spraying steam onto garments.

[0002] Typically, the iron module that includes a steam iron is different from a regular iron in that the steam generating unit that generates steam and the steam iron that discharges steam are placed separately and connected by a cable.

[0003] Since these steam irons are installed separately from the steam generator, they have the advantage of being lighter than regular irons that have the steam generator and heating plate integrated into one, and they can freely move in three directions and spray steam within the range allowed by the cable without being restricted by the installation location of the steam generator, so they have the effect of removing wrinkles even when clothes are placed on a hanger or the like.

[0004] Accordingly, various ironing modules have recently emerged in which the steam iron, which sprays steam, and the steam generating unit, which generates steam, are separately arranged. (See U.S. Patent Application Publication No. 2008 / 0040953)

[0005] However, when the power to the steam generating unit of these iron modules is turned off, the temperature inside the steam generating unit decreases, and as the temperature decreases, the high-temperature air remaining inside condenses.

[0006] Therefore, as the air condenses into water, the internal pressure decreases, and external air is supplied into the steam generating section by negative pressure.

[0007] The steam valve, which opens and closes by connecting the above steam iron and the steam generator, closes when the power of the steam generator is turned off, and is connected to the lower part of the steam generator so as to communicate with the outside, and air is supplied through the open inlet.

[0008] Since water is stored in the lower part of the steam generator, there is a problem in that bubbles are generated in the water stored inside the steam generator by the supplied air, and noise is generated due to the generation of the bubbles.

[0009] The present invention aims to provide a clothing treatment device that reduces noise generated after using a steam iron.

[0010] The present invention aims to provide a clothing treatment device that prevents the formation of bubbles in water remaining in a steam generating unit.

[0011] The present invention aims to solve the problem of providing a clothing treatment device that opens and closes a steam valve according to temperature changes.

[0012] The present invention, in order to solve the above-described problem, comprises a cabinet, an inner case provided inside the cabinet to provide a space for accommodating clothes, a machine room disposed under the inner case and provided to supply at least one of hot air and steam to the inside of the inner case, and a steam iron provided to be withdrawable forward in the machine room to supply steam to the surface of the clothes, wherein the machine room includes a steam generating unit provided to receive water and generate steam supplied to the steam iron, a water supply tank for storing water supplied to the steam generating unit, a water supply pump for receiving water from the water supply tank and supplying it to the steam generating unit, a supply pipe for guiding the water supplied from the water supply pump to the steam generating unit, a cable for connecting the steam generating unit and the steam iron to guide the steam, and a steam valve provided to open and close the cable and controlled to close the cable when the power of the steam iron is cut off or the operation of the steam generating unit is terminated, and the steam valve is controlled to close the cable when the power of the steam iron is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit. If the cable is blocked or the operation of the steam generator is terminated, the cable can be controlled to be opened again.

[0013] In order to solve the above-described problem, the steam valve can close the cable again after a certain period of time has passed when the cable is opened.

[0014] In order to solve the above-described problem, the present invention can be controlled so that when the power of the steam iron is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit, the steam valve closes the cable if steam remains inside the steam generating unit, and opens the cable again while the steam is condensed inside the steam generating unit.

[0015] In order to solve the above-described problem, the steam valve can be controlled to re-seal the cable after all of the steam is condensed inside the steam generating unit.

[0016] In order to solve the above-described problem, the present invention is characterized in that, when the power of the steam iron is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit, the steam valve is controlled to close the cable until the inside of the steam generating unit reaches a vaporization temperature at which steam is generated or a first temperature lower than the vaporization temperature, and the inside of the steam generating unit can be controlled to open the cable until the inside of the steam generating unit reaches a second temperature lower than the vaporization temperature or the first temperature.

[0017] In order to solve the above-described problem, the difference between the first temperature and the second temperature can be set to be much larger than the difference between the vaporization temperature and the first temperature.

[0018] In order to solve the above-described problem, the steam valve can be controlled to close the cable again when the inside of the steam generating unit drops below the second temperature.

[0019] In order to solve the above-described problem, the second temperature can be set to a temperature higher than room temperature or the temperature outside the cabinet.

[0020] In order to solve the above-described problem, the present invention can be controlled so that, after the steam is generated in the steam generating unit, when the power of the steam iron is cut off or the operation of the steam generating unit is terminated, the cable is opened for at least a certain period of time so that air can flow into the steam generating unit from the steam iron.

[0021] In order to solve the above-described problem, the steam generating unit may be provided so as to accommodate a certain amount of water inside when the power of the steam iron is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit.

[0022] In order to solve the above-described problem, the present invention further includes a drainage pipe for collecting water condensed in the inner case and the steam generating unit, a drainage pipe for guiding water inside the steam generating unit to the drainage pipe, and a drainage valve for opening and closing the drainage pipe, and the drainage valve can be controlled to close the drainage pipe in a state where a certain amount of water remains inside the steam generating unit when the power of the steam iron is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit.

[0023] In order to solve the above-described problem, the end of the supply pipe can be connected to the lower part of the steam generating unit.

[0024] In order to solve the above-described problem, the end of the supply pipe can be connected closer to the lower end than the upper end of the steam generating unit.

[0025] The present invention has the effect of reducing noise generated after using a steam iron.

[0026] The present invention has the effect of preventing bubbles from forming in water remaining in a steam generating unit.

[0027] The present invention has the effect of opening and closing a steam valve according to temperature changes.

[0051] Figure 1 illustrates an embodiment in which the ironing module (S) of the present invention is installed in a clothing treatment device equipped with a clothing manager.

[0052] The ironing module (S) of the present invention can be installed in a machine room located inside or below the door of the garment treatment device.

[0053] Specifically, the garment treatment device may include a cabinet (100) forming an exterior and a door (120) rotatably coupled to the cabinet (100).

[0054] The above door (120) may include a main body (121) forming the front of the cabinet (100), and an installation body (122) extending from one side of the main body (121) and on which a display for displaying information of the clothing treatment device may be installed.

[0055] 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.

[0056] The above installation body (122) can be extended from the main body (121) toward the rear of the cabinet (100) to form a step.

[0057] 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.

[0058] A handle (123) may be provided in the stepped area of ​​the above-mentioned installation body (122) and the main body (121).

[0059] 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.

[0060] The above cabinet (100) and the above door (120) may be made of metal.

[0061] Figure 2 illustrates the interior of the cabinet of the garment treatment device of the present invention.

[0062] 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.

[0063] 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).

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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).

[0068] 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.

[0069] 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.

[0070] 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).

[0071] 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.

[0072] 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).

[0073] 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).

[0074] 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).

[0075] 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.

[0076] 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).

[0077] 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).

[0078] The above door (120) can be rotatably coupled to the above cabinet (100).

[0079] 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).

[0080] When the above door (120) is closed, the opening (210) and the machine room (300) can be prevented from being exposed to the front.

[0081] 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).

[0082] 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).

[0083] 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).

[0084] 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).

[0085] 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).

[0086] 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).

[0087] 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).

[0088] 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).

[0089] 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).

[0090] 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).

[0091] 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).

[0092] 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).

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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).

[0097] 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.

[0098] 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).

[0099] Figure 3 illustrates the exterior of the machine room (300).

[0100] 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.

[0101] 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.

[0102] 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.

[0103] The above ironing module (S) can be installed in the above machine room.

[0104] The above ironing module (S) may be provided to supply heat and steam to the surface of the clothing.

[0105] The above ironing module (S) may further include a storage box (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).

[0106] The storage box (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.

[0107] 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.

[0108] 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.

[0109] 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 box (1200).

[0110] 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.

[0111] 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.

[0112] 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).

[0113] 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 room (300).

[0114] The above water supply tank (301) and drain tank (302) can share the iron module (S) and the above refresh module (T).

[0117] 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).

[0118] Specifically, the refresh module (T) may include a base part (310) that supports the various devices described above or provides a space for installation, a circulation duct (320) that is installed or extended from the base part (310) and provides a path for air inside the inner case (200) or air outside the cabinet (200) to move, a blower part (350) that is mounted on the circulation duct (320) and provides power to move the air, a heat supply part (340) that cools and heats the air moving along the circulation duct (320) to generate hot air, and a steam supply part (800) that is supported on the base part (310) or mounted on the circulation duct (320) and supplies steam to the inside of the inner case (200).

[0119] The above base part (310) may be provided as a plate on which various devices are installed.

[0120] 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.

[0121] 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.

[0122] 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).

[0123] 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.

[0124] The above water supply tank and the above drain tank may also be included in the above refresh module (T).

[0125] 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).

[0126] 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.

[0127] The above refresh module (T) may include a base cover (360) provided to connect the circulation duct (320) and the inlet hole (232).

[0128] 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).

[0129] 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).

[0130] 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).

[0131] The steam supply unit (800) can be connected to the water tank (301) to receive water and generate steam. The steam supply unit (800) can be installed and positioned on the upper portion of the circulation duct (320). The steam supply unit (800) can be positioned at the rear of the base cover (360).

[0132] The above refresh module (T) may further include a steam nozzle (900) that receives steam from the steam supply unit (800) and supplies it to the inside of the inner case (200). The steam nozzle (900) may be placed between the steam supply unit (800) and the steam hole (233).

[0133] The water that is condensed and cannot be discharged from the steam nozzle (900) to the steam hole (233) can be recovered back to the steam supply unit (800).

[0134] The above blower (350) may be provided to communicate with the circulation duct (320) and the discharge hole (231).

[0135] 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).

[0136] 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).

[0137] Figure 5 illustrates the rear of the machine room.

[0138] 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).

[0139] 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).

[0140] 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).

[0141] 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).

[0142] 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).

[0143] Figure 6 illustrates the circulation duct and base structure in the machine room of the garment treatment device of the present invention.

[0144] The above base portion (310) can form the lower surface of the clothing treatment device.

[0145] 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.

[0146] 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.

[0147] 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).

[0148] 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).

[0149] 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).

[0150] 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).

[0151] 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).

[0152] 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).

[0153] 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).

[0154] 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.

[0155] 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.

[0156] 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).

[0157] 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).

[0158] 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).

[0159] Figure 7 illustrates the inside of the circulation duct of the clothing treatment device of the present invention.

[0160] The above circulation duct (320) can extend upward from the base floor to form a path through which air flows.

[0161] 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).

[0162] 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.

[0163] 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).

[0164] 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).

[0165] 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).

[0166] 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).

[0167] 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).

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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).

[0172] 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).

[0173] The length of the above ironing module (S) may be provided to be longer than the length of the above circulation duct (320).

[0174] Figure 8 illustrates a water supply and drainage system of the clothing treatment device of the present invention.

[0175] The clothing treatment device of the present invention may include a water supply tank (301) that supplies water to the steam supply unit (900) and a drain tank (302) that collects water condensed in the circulation duct (320) or ironing module (S).

[0176] 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).

[0177] 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).

[0178] The above detachable part (380) is provided in a plate shape to prevent the inside of the machine room (300) from being exposed.

[0179] 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).

[0180] The above ironing module (S) may be provided so that a part thereof penetrates the detachable portion (380).

[0181] 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.

[0182] 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.

[0183] Figure 9 illustrates the installation structure of a steam supply unit that receives water from a water tank.

[0184] The above steam supply unit (800) can be supported by being installed on the base cover (360).

[0185] The above base cover (360) may include an inlet body (361) that is coupled to the upper surface of the circulation duct (320) to connect the inner case (200) and the circulation duct (320), and a shielding body (363) that extends from the inlet body (361) to shield the upper surface of the circulation duct (320).

[0186] The above inlet body (361) may be provided in a duct shape to communicate between the inlet hole (231) of the inner case and the inside of the circulation duct (320). The inlet body (361) may be provided to protrude further upward than the shielding body (363).

[0187] The above inlet body (361) may be placed in front of the evaporator (341) so as not to face the evaporator (341) and the condenser (343).

[0188] The above inlet body (361) can serve as an inlet duct that moves air from the inner case (200) to the circulation duct (320). The inlet body (361) can be provided with an inlet portion (362) therein through which air from the inner case (200) can pass.

[0189] The above inlet (362) may be provided in multiple sections, and a filter may be inserted and installed in one of the sections.

[0190] The above shielding body (363) may include a shielding panel (3631) that blocks the evaporator (341) and the condenser (343) from being exposed to the outside and supports the steam supply unit (800), a power terminal (3632) that extends from the shielding panel (3631) or the inlet body (361) to supply power to the steam supply unit (800), and a protection panel (3632) that accommodates and protects one of both sides of the steam supply unit (800).

[0191] The outer surface of the above protective panel (3632) may be provided with a plurality of reinforcing ribs to enhance rigidity. This prevents vibrations or shocks generated in the inner case (200) or machine room (300) from being transmitted to the steam supply unit (800).

[0192] The above steam supply unit (800) can be supported by being mounted on the base cover (360).

[0193] The above steam supply unit (800) may include a steam case (810) that stores water that generates the steam.

[0194] The above steam supply unit (800) may further include an installation bracket (870) that can fix the steam case (810) to the base cover (360).

[0195] The above installation bracket (870) can be coupled to the base cover (360) to fix the steam case (810).

[0196] The above installation bracket (870) may include a lower panel (871) that supports the lower surface of the steam case (810) and a side panel (872) that supports both sides of the steam case (810) on the lower panel (871).

[0197] The above-mentioned installation bracket (870) may further include a support panel (873) that extends stepwise from the lower panel (871) to support the lower surface of the steam case (810). As a result, the lower panel (871) may receive and support a portion of the bottom surface of the steam case (810).

[0198] The compressor (343) may be placed below the steam supply unit (800).

[0199] The above installation bracket (870) may be provided to block heat generated from the compressor or heat generated from the refrigerant compressed in the compressor from being transferred to the steam supply unit (800).

[0200] The above installation bracket (870) can also prevent the fire from spreading to the steam supply unit (800) in the event of a fire occurring in the compressor (343).

[0201] Meanwhile, the base cover (360) may include a fastening portion (3631) that is provided on the shielding body (363) and detachably coupled to the steam supply unit (800). The fastening portion (3631) may be provided with a structure that detachably couples with a protrusion protruding from the lower portion of the steam case (810).

[0202] Accordingly, even if a large amount of water is contained inside the steam case (810), the steam case (810) can be stably placed on the base cover (360).

[0203] In addition, since the steam case (810) is positioned above the circulation duct (320) and the distance from the inner case (200) becomes shorter, it is possible to minimize condensation of the steam generated in the steam case (810) before it reaches the inner case (200).

[0204] Figure 10 illustrates a structure for supplying water to the steam supply unit.

[0205] Steam generated inside the above steam case (810) can be supplied directly into the inner case (200) through the steam pipe (823).

[0206] However, if steam is directly supplied into the inner case (200) through the steam pipe (823), there is a risk that water contained in the steam case (810) will also be discharged into the inner case (200). In addition, there is a risk that the water heated in the steam case (810) will heat the bottom surface of the inner case (200), causing heat damage to the inner case (200).

[0207] To prevent this, the steam supply unit (800) of the present invention may further include a steam nozzle (900) that receives steam generated in the steam case (810) and supplies it to the inner case (200).

[0208] The above steam nozzle (900) may be positioned apart from the steam case (810) and may be provided so as to receive only steam formed in the steam case (810) and not receive water contained in the steam case (810).

[0209] For example, the steam nozzle (900) may be positioned above the steam case (810) and connected to a steam pipe (813). Accordingly, the steam generated in the steam case (810) rises due to the density difference and is supplied to the steam nozzle (900) along the steam pipe (833), and the water contained in the steam case (810) may not flow into the steam pipe (833) or the steam nozzle (900) due to gravity.

[0210] The above steam nozzle (900) can be placed between the bottom surface of the inner case (200) and the steam case (810), and can be provided to communicate with the steam hole (233).

[0211] Meanwhile, the steam supply unit (800) of the present invention is provided to receive water from the water supply tank (301) and generate steam.

[0212] To this end, the garment treatment device of the present invention may include a water supply unit (880) that supplies water contained in the water supply tank (301) to the steam supply unit (800).

[0213] The above water supply unit (880) may include a water supply pump (881) that provides pressure to supply water supplied to the water supply tank (301) to the steam supply unit (800) or the steam nozzle (900), a supply pipe (882) that is connected to the water supply tank (301) and delivers water to the water supply pump (881), and a connection pipe (883) that connects the water supply pump (880) and the steam nozzle (900).

[0214] The above supply pipe (882) may be provided as a hose connecting the water supply tank (301) and the water supply pump (881), and the above connection pipe (883) may be provided as a hose connected to the water supply pump (881).

[0215] The clothing treatment device of the present invention may be equipped to supply water contained in the water tank (301) to the steam nozzle (900) rather than the steam case (810).

[0216] The above water supply pump (881) may not be directly connected to the steam case (810).

[0217] The above steam nozzle (900) can receive water through the connection pipe (883) and then supply water to the steam supply unit (800) through the water supply pipe (884). The water supply pipe (884) can be connected to the return pipe (824).

[0218] Since the steam nozzle (900) is positioned above the steam case (810), water supplied to the steam nozzle (900) can be automatically supplied to the steam case (810) through the water supply pipe (884).

[0219] The steam pipe (823) through which steam is introduced into the steam nozzle (900) and the return pipe (824) through which water is discharged from the steam nozzle (900) may be provided as separate flow paths. Accordingly, the water supplied from the steam nozzle (900) can be prevented from interfering with the movement of the steam supplied from the steam case (810).

[0220] Meanwhile, the water supply pipe (884) may be provided in a U-shape. That is, the middle region of the water supply pipe (884) may be arranged to be lower in height than the two ends. As a result, a certain amount of water, such as a water trap, may be accumulated in the water supply pipe (884), thereby preventing steam or water supplied from the steam case (810) through the water supply pipe (884) from being re-introduced.

[0221] In addition, since the steam case (810) is not directly connected to the water supply pump (881), the possibility of water flowing into the steam case (810) flowing back to the water supply pump (881) can be blocked.

[0222] In addition, a large amount of water can be supplied to the steam nozzle (900) at a considerable pressure through the water supply pump (810). As a result, foreign substances or bacteria that are growing in the steam nozzle (900) can be washed away by the water supplied to the steam nozzle (900) and moved down into the steam case (810). Therefore, the steam nozzle (900) can always be maintained in a clean state.

[0223] Meanwhile, when the steam supplied from the steam nozzle (900) is condensed, the condensed water can be reintroduced into the steam case (810) through the water supply pipe (884). That is, the condensed water generated from the steam nozzle (900) can be recovered into the steam case (810) in the same direction as the movement of the water supplied from the water supply pump (800) and can be recycled as water that generates the steam. Therefore, the garment treatment device of the present invention can prevent the water level of the water supply tank (301) from rapidly decreasing and can also prevent waste of water.

[0224] Figure 11 illustrates the drainage structure of the clothing treatment device of the present invention.

[0225] 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.

[0226] The water condensed in the above evaporator (341) may accumulate on the lower surface of the above circulation duct (320).

[0227] 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).

[0228] 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).

[0229] The above reservoir (326) can be formed by sinking downward from the bottom surface of the circulation duct (320).

[0230] 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.

[0231] The above reservoir (326) may have at least a portion of its upper surface arranged parallel to the heat exchanger installation portion (3212).

[0232] The above base portion (310) may include a guide pipe (3263) that discharges water collected in the reservoir (326) to the outside.

[0233] 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).

[0234] 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).

[0235] Figure 12 illustrates the drainage tank installation structure of the clothing treatment device of the present invention.

[0236] The above drainage tank (302) may be provided in a box shape for storing water.

[0237] 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).

[0238] 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.

[0239] 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).

[0240] 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.

[0241] 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).

[0242] 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).

[0243] 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).

[0244] 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).

[0245] 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.

[0246] 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).

[0247] 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.

[0248] 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).

[0249] 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.

[0250] 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).

[0251] 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).

[0252] 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).

[0253] Figure 13 illustrates in detail the structure of the reflux section of the clothing treatment device of the present invention.

[0254] 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).

[0255] 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.

[0256] 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).

[0257] 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).

[0258] 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).

[0259] 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).

[0260] 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).

[0261] 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).

[0262] Figure 14 illustrates the lower configuration of the bottom surface of the inner case.

[0263] 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).

[0264] 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.

[0265] 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).

[0266] 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).

[0267] 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).

[0268] 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).

[0269] 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.

[0270] 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).

[0271] 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 a steam generating unit (2100) that receives water and heats it to generate at least one of heat and steam supplied to the steam iron (1300).

[0272] 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.

[0273] 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).

[0274] 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).

[0275] 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.

[0276] 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.

[0277] 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).

[0278] 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.

[0279] Figure 15 illustrates in detail the structure of the above iron module.

[0280] 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.

[0281] 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.

[0282] 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.

[0283] 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.

[0284] The above storage module (1000) may include a steam iron (1300) capable of accessing the clothing and supplying at least one of heat and steam to the clothing.

[0285] The above steam iron (1300) is provided with a surface facing the clothing made of a material capable of transmitting heat, so that when it comes into contact with the clothing, it can remove wrinkles from the clothing.

[0286] 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.

[0287] 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).

[0288] 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.

[0289] The above storage module (1000) may further include a storage box (1200) for accommodating the steam iron (1300). The storage box (1200) may be provided in the shape of a case having a storage space for storing the steam iron (1300) therein.

[0290] The storage box (1200) above serves to store the steam iron (1300) inside the machine room (300), and the steam iron (1300) can be stored at a variable location inside the machine room (300).

[0291] The width of the storage box (1200) may be provided to be greater than the width of the steam iron (1300), and the length of the storage box (1200) may be provided to be greater than the length of the steam iron (1300).

[0292] For example, the width of the storage box (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 box (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 box (1200).

[0293] The storage box (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 vertical direction is longer than the width in the left-right direction. Accordingly, the steam iron (1300) can be stably placed and stored inside the storage box (1200).

[0294] The storage box (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.

[0295] 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.

[0296] 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.

[0297] 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).

[0298] The above storage module (1300) may further include a withdrawal portion (1100) that exposes the steam iron (1300) to the front of the storage box (1200).

[0299] The above-mentioned withdrawal portion (1100) may be provided to support the steam iron (1300) inside the storage box (1200). The steam iron (1300) may be secured to the withdrawal portion (1100) and stored inside the storage box (1200).

[0300] The above-described withdrawal portion (1100) may be provided to expose at least a portion of the steam iron (1300) stored inside the storage box (1200) to the outside of the storage box (1200). The withdrawal portion (1100) may withdraw the steam iron (1300) to the front of the storage box (1200) so that the steam iron (1300) may be exposed to the front of the machine room (300) or the detachable portion (380). Accordingly, even if the steam iron (1300) is stored in the storage box (1200), the steam iron (1300) may be easily withdrawn to the outside of the machine room (300).

[0301] The above withdrawal part (1100) may be provided as a drawer type that is withdrawn forward from the storage box (1200), or may be provided as a hatch type that is opened by rotating forward from the front of the storage box (1200).

[0302] The above-mentioned withdrawal part (1100) may be provided in any configuration as long as it can selectively expose the steam iron (1300) to the front of the storage box (1200) while storing the steam iron (1300) inside the storage box (1200).

[0303] The above-mentioned withdrawal part (1100) may include a support part (1120) on which the steam iron (1300) is mounted, and a cover (1130) provided in front of the support part (1120) to shield the open surface (1220).

[0304] The above support member (1120) may be provided to be accommodated in the storage box (1200) and to fix the steam iron (1300). The support member (1120) may be provided in the shape of a case that accommodates the steam iron (1300), or may be provided in the shape of a plate that supports the lower part of the steam iron (1300). The support member (1120) may be provided as a drawer that is accommodated in the storage body (1210) and is drawn in and out through the open surface (1220).

[0305] When the support member (1120) is pulled out from the open surface (1220), the steam iron (1300) mounted on the support member (1120) can be pulled out to the front of the storage box (1200), and when the support member (1120) is inserted into the open surface (1120), the steam iron (1300) mounted on the support member (1120) can be completely accommodated in the storage box (1200).

[0306] The above-described withdrawal portion (1110) may further include a cover panel (1130) extending from the front of the support portion (1120) to shield the open surface (1220). The cover panel (1130) may be provided to prevent the interior of the storage body (1210) from being exposed to the outside through the open surface (1220). As a result, not only the steam iron (1300) accommodated in the storage body (1210), but also the entire interior of the iron module (S) can be prevented from being contaminated with foreign substances, steam, or air.

[0307] The above cover panel (1130) may be provided so as to shield a through hole provided to allow the withdrawal portion (1110) to be withdrawn from the detachable portion (380). As a result, the inside of the machine room (300) can be prevented from being exposed to the outside due to the through hole, and foreign substances, steam, and air can be prevented from entering the inside of the machine room (300).

[0308] The area of ​​the commercial cover panel (1130) may be wider than the front surface area of ​​the support member (1120). The area and shape of the cover panel (1130) may be provided in an area and shape that can completely shield the space where the iron module (S) is exposed in the detachable member (380).

[0309] The width of the cover panel (1130) may be the same as the width of the support portion (1120) or the width of the open surface (1220), and the height of the cover panel (1130) may be higher than the height of the support portion (1120) and the same as the height of the open surface (1220).

[0310] The upper portion of the cover panel (1130) may be provided with a recessed portion (1150) that is recessed inward, and a pull-out handle (1140) positioned on the upper portion of the recessed portion (1150).

[0311] The above withdrawal part (1100) may be provided with a guide groove (1110) at the lower portion of the support part (1120) to guide the support part (1120) to slide forward and backward without moving left and right.

[0312] The above guide groove (1110) can be mounted on a rail provided within the storage body (1210) or a rail (3300) provided on the base module (3000) and inserted into the storage body (1210). When the guide groove (1110) moves forward and backward along the rail (3300), the entire withdrawal portion (1100) can be withdrawn or inserted into the open surface (1220).

[0313] The storage body (1210) may be provided with an insertion hole in the lower back surface into which the rail (3300) can be inserted. In addition, the storage body (1210) may be provided with an open hole through which a cable (1400) extending from the heating module (2000) can pass through the back surface.

[0314] The above insertion hole and the above opening hole may be provided as one piece.

[0315] However, the steam iron (1300) can be prevented from being pulled out or exposed through the insertion hole and the opening hole. For example, the insertion hole and the opening hole can be positioned lower than the support member (11120) or the steam iron (1300).

[0316] The heating module (2000) may include a heating generator (2100) that supplies heat and steam to the steam iron (1300). The heating generator (2100) may receive power to heat a wire and transmit the heat to the steam iron (1300) through the cable (1400), or may heat water to generate steam and transmit the steam to the steam iron (1300) through the cable (1400).

[0317] For example, the heating generation unit (2100) may be provided as a steam generation unit that generates steam by receiving electricity and water.

[0318] The above steam generating unit (2100) may be provided separately from the steam supply unit (800) installed in the machine room (300). The steam generating unit (2100) may be provided to receive water and electricity and heat the water to generate steam.

[0319] In addition, the steam generating unit (2100) may be provided to supply steam to the steam iron (1300) and generate steam at a higher pressure than the steam supply unit (800) so that the steam supplied to the steam iron (1300) can be sprayed onto clothing.

[0320] The above steam generating unit (2100) can be coupled with a connector (2800) that receives power, and can include a pressure sensor that detects the pressure of steam generated inside.

[0321] The above steam generating unit (2100) may be configured in any way as long as it can receive water and heat steam. The steam generating unit (2100) may include a steam container forming an exterior and a steam heater provided inside the steam container to heat water.

[0322] Additionally, the heating module (2000) may be connected to a high-pressure pump (2200) that increases the pressure inside the steam generating unit (2100) to generate high-pressure steam.

[0323] 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 module (2000) can be mounted and fixed to the base module (3000).

[0324] 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).

[0325] 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.

[0326] 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.

[0327] 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.

[0328] The above base panel (3200) may be provided integrally with the base portion (310).

[0329] 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).

[0330] 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.

[0331] 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 to discharge water from the heating module (2000) can be installed.

[0332] Furthermore, because the storage module (1000) and the heating module (2000) are positioned above the drainage structure 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.

[0333] The above-mentioned fixing panel (3100) may be provided to extend upward from both sides of the base panel (3200).

[0334] 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.

[0335] Figure 16 illustrates the supply and drainage structure of the heating module (2000).

[0336] In order for the above steam generating unit (2100) to generate steam and transmit it to the steam iron (1300), it is necessary to supply water.

[0337] To this end, the steam generator (2100) may include a high-pressure pump (2200) connected to a water source to supply water to the steam generator (2100).

[0338] The above high-pressure pump (2200) may be provided to communicate with a water supply tank (301) and receive water from the water supply tank (301).

[0339] Of course, the high pressure pump (2200) can supply water to the steam generator (2100) through a separate water source other than the water tank.

[0340] Meanwhile, the high-pressure pump (2200) can supply water not only by simply supplying water to the steam generator (2100), but also by increasing the pressure inside the steam generator (2100). As a result, water can be heated while the pressure inside the steam generator (2100) is higher than atmospheric pressure, thereby generating high-pressure steam.

[0341] The above steam generating unit (2100) may be equipped with a pressure sensor (2300) that measures internal pressure.

[0342] The pressure sensor (2300) can be connected to an outlet (2150) extending from the body portion (2110), and a steam valve (2800) that opens and closes the outlet (2150) can be coupled.

[0343] The above steam valve (2800) can be controlled by the control panel of the iron module (S). The steam valve (2800) can be opened and closed according to the pressure and temperature inside the body (2110) or the pressure and temperature of the outlet (2150).

[0344] The above cable (1400) can have one end connected to the steam valve (2800) and the other end connected to a steam iron (1300).

[0345] When the steam valve (2800) is opened, steam generated in the steam generating unit (2100) can be supplied to the steam iron (1300), and when the steam valve (2800) is closed, the supply of both water and steam to the steam iron (1300) can be blocked.

[0346] The above pressure sensor (2300) can induce the high-pressure pump (2200) to operate more when the pressure of the steam generator (2100) is lower than the reference pressure, and can induce water or steam to be drained from the inside of the steam generator (2100) when the pressure of the steam generator (2100) is higher than the reference pressure.

[0347] For example, the reference pressure may be set to 1 bar to 3 bar higher than atmospheric pressure.

[0348] The above steam generating unit (2100) can be mounted on the base module (3000) and fixed using a fastening member, etc., and the above high-pressure pump (2200) can also be mounted on the base module (3000).

[0349] The above heating module (2000) may include a pump connection pipe (2540) that connects the high-pressure pump (2200) and the steam generation 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 steam generation unit (2100).

[0350] The above high-pressure pump (2200) may include a pump discharge pipe (2210) that supplies and discharges water, and a pump supply pipe (2211) that extends from the pump discharge pipe (2210) and supplies water to the pump connection pipe (2540).

[0351] The above pump supply pipe (2211) may be provided by branching from the pump discharge pipe (2210) so as to effectively transfer water of various pressures or high pressures, and the pump connection pipe (2540) may also be provided in the form of a single pipe at one end, but may be formed as a plurality of branch pipes at the other end so as to be connected to the pump supply pipe (2211).

[0352] The above water supply structure (2500) may include a water supply connection pipe (2510) that supplies water from the water source to the steam generator (2100) or high-pressure pump (2200), and a branch supply pipe (2530) that supplies the water from the high-pressure pump (2200) to the steam generator (2100).

[0353] Meanwhile, when the steam generating unit (2100) stops operating or when the steam generated from the steam generating unit (2100) condenses to form water, a drainage device (2400) for discharging water inside the steam generating unit (2100) may be included.

[0354] 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 steam generation unit (2100) and may be equipped to receive water from the drain outlet (216) of the steam generation unit (2100).

[0355] The above drainage structure (2600) may be provided to discharge water condensed in the steam generator (2100) or collected in the drainage device (2400).

[0356] The above drainage structure (2600) may include a drainage connection pipe (2610) extending from the drainage device (2400) to the drain port (2160), and an inlet pipe (2620) coupled to the drainage connection pipe (2610) to guide water discharged from the drainage device (2400) to a drain tank (302).

[0357] 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 steam generator (2100) is unified, simplifying the flow path and saving space.

[0358] 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).

[0359] 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).

[0360] 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 steam generation 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 steam generation unit (2100) and a conduit for discharging water from the steam generation unit (2100).

[0361] The above drainage device (2400) can be controlled by an independent control unit described later.

[0362] Figure 17 illustrates a structure in which the above water supply structure and the above water supply unit are connected.

[0363] The above ironing module (S) is installed separately and independently from the structure of the machine room (300), but may be installed to communicate with the water supply unit (880) provided in the machine room (300).

[0364] As a result, the ironing module (S) may be provided so that it can receive water from the 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 inside of the inner case (200) and the steam iron (1300) through a single water tank (301).

[0365] Meanwhile, when the steam supply unit (800) is driven, the steam generation unit (2100) is not driven, and when the steam generation unit (2100) is driven, the steam supply unit (800) is controlled not to be driven.

[0366] To this end, the garment treatment device of the present invention may further include a switching valve (890) provided to selectively supply water contained in the water tank (301) to the steam supply unit (800) and the steam generation unit (2100).

[0367] The above switching valve (890) can be placed between the water supply pump (881) and the supply pipe (882) and can be controlled by the main control unit (700).

[0368] The above switching valve (890) may be provided as a three-way valve.

[0369] When the above door is closed or one or more of the above refresh module (T) is operated, the switching valve (890) can be controlled to communicate the water tank (301) and the water supply pump (881), and the water tank (301) and the water supply structure (2500) can be controlled to block the communication.

[0370] When one or more of the above door opening and the refresh module (T) terminating operation occurs, the switching valve (890) can be controlled to block the communication between the water tank (301) and the water supply pump (881), and the water tank (301) and the water supply structure (2500) can be controlled to communicate.

[0371] When the above switching valve (890) connects the water supply tank (301) and the water supply structure (2500), the water supply connection pipe (2510) can receive water from the water supply tank (301) and transfer it to the high-pressure pump (2200).

[0372] The above water supply connection pipe (2510) can have one end connected to the water supply (2501) and the other end connected to the high-pressure pump (2200).

[0373] Of course, the above-mentioned switching valve (890) may be provided as a simple T-shaped pipe rather than a valve that changes the flow path. In this case, when the above-mentioned feed pump (881) is not driven and only the above-mentioned high-pressure pump (2200) is driven, water in the above-mentioned feed tank (301) may be introduced into the above-mentioned high-pressure pump (2200) by negative pressure. The water introduced into the above-mentioned high-pressure pump (2200) may be introduced into the above-mentioned steam generator (2100) through the above-mentioned pump connection pipe (2540), etc.

[0374] In addition, when the above-mentioned water supply pump (881) is driven and the above-mentioned high-pressure pump (2200) is not driven, water in the above-mentioned water tank (301) can be supplied to the above-mentioned water supply pump (881) by negative pressure and moved along the connecting pipe (833) to be supplied to the steam supply unit (800).

[0375] Regardless of the configuration of the above switching valve (890), when the steam generating unit (2100) is operated to generate steam, the steam can be transmitted to the steam iron (1300) along the cable (1400) and sprayed to the outside of the steam iron (1300).

[0376] If the above steam nozzle (900) is provided separately, water supplied through the water supply pump (881) can be supplied to the steam nozzle (900) and then supplied to the steam supply unit (800).

[0377] As a result, the garment treatment device of the present invention can supply water contained in the water tank (301) to both the steam supply unit (800) and the steam generation unit (2100). Therefore, the installation of a separate water tank for the ironing module (S) can be omitted.

[0378] Figure 18 illustrates a pre-existing structure that allows the above drainage structure and the above drainage section to communicate with each other.

[0379] 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).

[0380] 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.

[0381] 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).

[0382] 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).

[0383] 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).

[0384] 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).

[0385] 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).

[0386] In this way, a separate drain for the ironing module (S) can be omitted.

[0387] Figure 19 illustrates a structure in which the above drainage structure and the above drainage section are connected.

[0388] 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).

[0389] 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.

[0390] 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).

[0391] The above drainage structure (2600) may be provided to communicate with the drainage unit (330) through the circulation duct (320).

[0392] 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).

[0393] The water and residual water condensed in the steam generating 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 steam generating 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).

[0394] The above injection pipe (2620) may be provided to communicate with the inside of the circulation duct (320).

[0395] 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).

[0396] 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).

[0397] When the above drain pump (331) is driven, the water collected in the reservoir (326) can be stored in the drain tank (302).

[0398] Figure 20 illustrates the structure of the above steam iron.

[0399] The steam iron (1300) of the present invention may include a gripping part (1310) connected to the cable (1400) so that the user can grip it by hand.

[0400] The above-mentioned holding unit (1310) may be provided to spray and supply at least one of water and steam to the surface of the clothing.

[0401] The above-mentioned grip portion (1310) may include a handle portion (1311) capable of supporting the weight of the steam iron (1300) and an extension portion (1312) extending from the upper end of the handle portion (1311).

[0402] The above-mentioned grip section (1310) may have an installation space formed therein through which steam can pass and in which various components can be installed, and at least one of steam and heat may be discharged from the end of the above-mentioned grip section (1310).

[0403] The above grip part (1310) is provided with a length longer than the width or thickness to prevent the user's body from being damaged by steam and heat discharged from the end of the grip part (1310).

[0404] The above grip portion (1310) may include a handle portion (1311) having a pipe shape or the like and providing an area that can be gripped by a user's hand, a bend portion (1312) that is bent from the handle portion (1311), and an extension portion (1313) that extends from the bend portion (1312) to the end.

[0405] The above handle portion (1311) is provided in a cylindrical shape to accommodate the cable (1400) and may be provided with a length longer than the diameter. This allows a space for the user to grip the cable.

[0406] The above-mentioned bending portion (1312) may be provided to bend within 90 degrees from the end of the handle portion (1311). Due to the bending portion (1312), at least one of steam and heat moving along the handle portion (1311) can easily come into contact with clothing.

[0407] The above-mentioned expansion portion (1313) may be provided with a cross-sectional area that is wider than that of the above-mentioned bending portion (1312) and the above-mentioned handle portion (1311). This allows for supplying at least one of steam and heat to a wide area.

[0408] A space can also be formed in the above-mentioned expansion portion (1313) to accommodate a heating device that heats the supplied steam and heat.

[0409] The above-mentioned grip part (1310) may be provided in two pieces to facilitate installation and accommodation of the internal configuration.

[0410] For example, the gripping part (1310) may include a lower gripping part (1310b) that forms a lower surface and a part of both sides of the gripping part (1310), and an upper gripping part (1310a) that may form the remaining part of the upper surface and both sides of the gripping part (1310).

[0411] The above-mentioned gripping portion (1310) may further include a converging portion (1314) that extends further from the extension portion (1313) toward the end but has a smaller cross-sectional area than the extension portion (1313). The converging portion (1314) may prevent the internal structure of the gripping portion from being arbitrarily discharged to the outside.

[0412] The above convergence portion (1341) is provided so that the interior thereof is permeable, so that at least one of the steam and heat transmitted to the expansion portion (1313) can be moved to the outside of the steam iron (1300).

[0413] The above steam iron (1300) is supported by the above-mentioned support member (1310) and may include a spray member (1320) that discharges water and steam supplied from the above-mentioned steam generating member (2100).

[0414] The above-mentioned injection unit (1320) may include a chamber unit (1321) that is coupled to the cable (1400) and supplies water and steam to be injected, an insulating receiving unit (1322) that prevents heat generated in the chamber unit from being transferred to the grip unit (1310), a fixing bracket (1323) that is coupled to the front of the chamber unit (1321) and prevents the chamber unit (1321) from being separated from the front of the grip unit (1310), and an injection cover (1324) that is arranged in front of the fixing bracket (1323) and shields the end of the grip unit (1310).

[0415] The above chamber portion (1321) provides a space for storing water and steam transmitted from the cable (1400), and may be provided to transmit the steam to the outside of the steam iron (1300).

[0416] The above chamber unit (1321) may be provided in the shape of a case that receives steam or water supplied from the steam generating unit (2100).

[0417] In this way, even if the steam condenses into water in the heater base (1320), it can be reheated and sprayed as steam, and even before the steam condenses into water, it can be prevented from being reheated and condensed into water.

[0418] The above spray cover (1324) can form the end of the steam iron (1300).

[0419] The above-mentioned spray cover (1324) may include a coupling surface (13241) coupled to the end of the grip portion (1310), an exposed surface (13242) extending from the coupling surface (13241) to form the end surface of the steam iron (1300), and an injection hole (13243) penetrating the exposed surface (13242) to inject steam to the outside.

[0420] The above injection cover (1324) may include a fixed fastening portion (13244) that can be fixed by being combined with the grip portion (1310) or an internal configuration, and may include guide ribs (13245) arranged on both sides of the injection hole (13243) to guide the movement of the steam.

[0421] The above-mentioned exposed surface (13242) may be provided flat so as to be in contact with the surface of clothing, and may be provided so as to transfer steam and heat generated in the chamber portion (1321) to the surface of the clothing.

[0422] The steam iron (1300) of the present invention may further include a fixing bracket (1323) that fixes the chamber part (1320) to the end of the grip part (1310).

[0423] The above fixed bracket (1323) may include a receiving circumference (13231) that receives the front surface of the chamber portion (1321), a transmission hole (13232) provided inside the receiving circumference to transmit at least one of steam and heat discharged from the chamber portion (1321) to the injection cover (1334), and an expansion body (13233) that is provided to extend from the receiving circumference (13231) and to contact the coupling surface.

[0424] The steam iron (1300) of the present invention may include an insulating receiving portion (1322) that receives the chamber portion (1321) and insulates the chamber portion (1321).

[0425] The above insulation receiving portion (1322) may include a receiving body (13221) that receives the chamber portion, a passage hole (13222) through which steam supplied from the cable (1400) passes through the rear of the receiving body (13221), and a power hole (13223) through which a power line extending from the cable (1400) passes.

[0426] The above-mentioned receiving body (13221) may be provided to receive all surfaces except the front surface of the heater base (1320) and may be provided with an insulating material.

[0427] This prevents the chamber part (1321) from cooling, thereby preventing steam from condensing inside the chamber part (1321) or reducing the thermal efficiency of the steam iron (1300).

[0428] The above-mentioned gripper (1310) may further include a steamer panel (1360) that can control the on / off of the iron module (S) and the amount of sprayed from the iron module (S). The steamer panel (1360) may be provided as a PCB panel.

[0429] The above steamer panel (1360) may be provided to control one or more of the steam generation unit (2100), the pressure sensor unit (2300), the temperature sensor unit (2320), the water supply structure, the drainage structure, and the steam valve (2800), and may be provided to allow the ironing module (S) to perform any mode for supplying steam and heat to clothing.

[0430] The above mode may include a first mode for spraying first steam onto the clothing, a second mode for spraying second steam in excess of the first steam, and a third mode for spraying third steam in excess of the second steam.

[0431] Meanwhile, the chamber part (1321) of the present invention may be equipped not only to receive and discharge steam, but also to reheat water and steam supplied from the cable (1400).

[0432] Specifically, the steam generating unit (2100) heats water to generate and discharge steam.

[0433] However, the steam generating unit (2100) and the steam iron (1300) are spaced apart by the length of the cable (1400), and during the process of steam passing through the cable (1400), the steam may at least partially condense into water due to heat exchange with the outside.

[0434] In addition, even if the steam generating unit (2100) generates and discharges steam at high pressure, the internal pressure of the steam iron (1300) corresponds to atmospheric pressure, so that the pressure decreases during the process of high pressure steam moving between the cable (1400) and the steam iron (1300), and water may condense.

[0435] For example, even if steam corresponding to 150 degrees Celsius and 4 bar is discharged from the steam generating unit (2100), it can be changed into steam of 100 degrees Celsius and 1 atm as it is transmitted to the cable (1400) and the steam iron (1300), and further can be changed into condensate of 100 degrees Celsius or lower.

[0436] In addition, even if only steam is normally supplied to the steam iron (1300), the steam may be condensed into water as it passes through the grip section (1310) and the injection section (1320) of the steam iron (1300).

[0437] In this case, water may be discharged from the steam iron (1300), causing the clothes to become wet.

[0438] To prevent this, the iron module (s) of the present invention may be equipped to reheat at least one of water and steam transmitted through the cable (1400) inside the steam iron (1300).

[0439] Since the above-mentioned grip part (1310) is a part that comes into contact with the user's body, the iron module (S) of the present invention may be provided so that the injection part (1320) is heated to reheat at least one of the water and steam supplied from the cable (1400).

[0440] Accordingly, even if water is supplied from the cable (1400) or some of the steam is condensed when passing through the spray unit (1320), it can be reheated in the spray unit (1320) and sprayed out of the steam iron (1300) in a steam state.

[0441] In addition, the steam iron (1300) of the present invention may be provided with a separate space for collecting condensate inside. Accordingly, even if water condenses inside the steam iron (1300) or the condensed water is transferred to the steam iron (1300), the water can be prevented from being discharged as is to the outside of the steam iron (1300).

[0442] In addition, the steam iron (1300) of the present invention may be equipped to reheat the collected water in the injection unit (1320) to regenerate it into steam and then discharge it.

[0443] The steam iron (1300) of the present invention may be provided with at least a portion of the spray unit (1320) configured to reheat the water and steam.

[0444] For example, since the chamber part (1321) is configured to directly communicate with the cable (1400), the chamber part (1321) can be provided to be heatable. In addition, all other components of the injection part (1320) are provided with an insulating material or a material having a high specific heat, so that the user can be prevented from being burned by the chamber part (1321) or from water condensing inside the chamber part (1321).

[0445] The above-mentioned gripper (1310) may be provided with an operation input unit (1370) that receives a command to control the iron module (S).

[0446] The above-mentioned operating input unit (1370) may include a power unit (1371) that determines the on / off of the chamber unit (1321) and the steam generating unit (2100), and a selection unit (1372) that selects an arbitrary mode that can adjust the heating intensity of the chamber unit (1321) and the steam generating unit (2100) to control the spray amount of the iron module (S).

[0447] The above power supply unit (1371) and the above selection unit (1372) may be provided in any configuration as long as they can receive user input, such as button type, slide type, or touch type.

[0448] Figure 21 illustrates a cross-section of the steam generating unit of the present invention.

[0449] The steam generating unit (2100) of the present invention may be provided to heat water to generate steam and supply it to the steam iron (1300).

[0450] However, when the steam generating unit (2100) and the steam iron (1300) are arranged to be spaced apart from each other and connected via the cable (1400), the steam generated in the steam generating unit (2100) may have a reduced power transmitted to the steam iron (1300) or may condense while passing through the cable (1400), preventing a sufficient amount of steam from being supplied to the steam iron (1300).

[0451] In other words, even if the steam generating unit (2100) generates a sufficient amount of steam and supplies it to the steam iron (1300), the steam discharged through the injection unit (1320) of the steam iron (1300) may be small in amount or water may be discharged.

[0452] Therefore, the iron module (S) of the present invention may be equipped so that the steam generating unit (2100) generates and discharges steam having a higher pressure than atmospheric pressure. Since the injection unit (1320) of the steam iron (1300) is placed in an atmospheric pressure state, the high-pressure steam having a higher pressure than atmospheric pressure in the steam generating unit (2100) can pass through the cable (1400) and be discharged as is to the injection unit (1320) due to the pressure difference.

[0453] In addition, even if the high-pressure steam generated in the steam generating unit (2100) is cooled to a certain level and a pressure drop occurs through heat exchange with the surroundings during the process of passing through the cable (1400) or passing through the steam iron (1300) and being discharged, if the high-pressure steam is higher than the atmospheric pressure, the high-pressure steam may not be cooled below 100 degrees Celsius, or may be maintained in a state where it is not condensed into water even if cooled. As a result, the steam generated in the steam generating unit (2100) may be discharged to the outside of the injection unit (1320) without any problem.

[0454] To this end, the steam generating unit (2100) does not discharge steam as it is through the outlet (2150) even when water is heated inside the steam body (2110) and steam is generated, but rather, the outlet (2150) is locked by the steam valve (2800) to continuously heat the steam. As a result, the steam generating unit (2100) can further heat the steam and water, thereby increasing the pressure of the steam to be higher than the atmospheric pressure.

[0455] Even if steam is generated inside the steam body (2110) and the water level inside the steam body (2110) decreases, the steam body (2110) needs to be continuously heated.

[0456] Accordingly, the heating heater (2130) may not be positioned inside the steam body (2110) to be submerged in the stored water, but may be attached to the surface of the steam body (2110) to heat the steam body (2110) itself. Accordingly, the heating heater (2130) can heat the steam body (2110) regardless of the water level inside the steam body (2110), and even if only steam is contained inside the steam body (2110), the steam pressure contained in the steam body (2110) can be increased by continuously heating the steam body (2110).

[0457] As a result, the steam generating unit (2100) can generate steam higher than atmospheric pressure by heating the water contained therein in the same manner as a pressure cooker.

[0458] The above heating heater (2130) may be attached to the lower surface of the steam body (2110). As a result, heat can be directly transferred to the water contained in the steam body (2110) to generate steam more quickly.

[0459] The steam generator (2100) may further include a thermostat (2121) that detects the temperature of the heating heater (2130). The thermostat (2121) may be provided to cut off power supplied to the heating heater (2130) when the heating heater (2130) is heated above a limit temperature, or may be provided to control ON / OFF of the heating heater (2130).

[0460] Meanwhile, even if it is high-pressure steam, the temperature, pressure, and amount of steam sprayed from the steam iron (1300) need to be precisely controlled to protect clothing. However, in a pressure range higher than atmospheric pressure, it is difficult to precisely measure the pressure of the steam generated from the steam generator (2100), and it may be difficult for the steam valve (2800) to open the outlet (2150) at a precise time.

[0461] Accordingly, the iron module (S) of the present invention can be equipped with a pressure sensor unit (2300) as a pressure switch that detects a set pressure so that the pressure and injection amount of steam can be accurately controlled even under high pressure conditions.

[0462] That is, the pressure switch may be configured to react immediately when the pressure at the outlet (2150) reaches a set specific pressure. Such a pressure switch may be any pressure switch disclosed in the public domain.

[0463] When the pressure switch detects a specific pressure, the steam valve (2800) can be controlled to immediately open the outlet (2150). Accordingly, steam of a specific pressure can be uniformly discharged whenever the steam generator (2300) operates.

[0464] Meanwhile, the temperature of steam at a specific pressure is determined according to the properties of water, and the total amount of steam (injection amount) is determined at the outlet (2150) having the same cross-sectional area.

[0465] Therefore, the iron module (S) of the present invention can spray steam having a specific pressure, temperature, and spray amount when the pressure switch is set to react to a specific pressure.

[0466] However, if the steam injection is determined by the pressure switch, the ironing module (S) of the present invention has a limitation in that it can only inject one type of steam, which is not suitable for processing various types of clothing.

[0467] For example, for garments made of common fabrics like cotton and towels, high steam rates and high temperatures can cause minimal damage. However, for fabrics vulnerable to moisture and temperature, such as silk and cashmere, lower steam rates and temperatures are recommended. Furthermore, thicker fabrics like jeans, coats, and blankets require a high amount of steam to remove wrinkles.

[0468] To this end, if pressure switches with various pressure conditions are installed in the steam generator (2300), multiple outlets (2150) must be installed to correspond to the pressure switches, and multiple cables (1400) and steam valves (2800) must also be installed, which causes the inconvenience of this.

[0469] To solve this, the iron module (S) of the present invention can control the opening and closing of the steam valve (2800) by also utilizing the temperature sensor unit (2120) that detects the temperature of the steam generator unit (2100). Specifically, when the temperature of the steam in the saturation state (saturated state) is determined, the pressure of the corresponding steam is also determined. Therefore, when the temperature of a pressure range different from a specific pressure detected by the pressure switch is detected by the temperature sensor, the steam generator unit (2100) can discharge steam at a pressure and temperature different from the specific pressure.

[0470] As a result, the iron module (S) of the present invention can accurately spray steam having two or more pressures, temperatures, and spray amounts by using both the pressure switch (2300) and the temperature sensor unit (2120).

[0471] The above temperature sensor unit (2120) may include at least one of a thermometer (2122) inserted into the steam generator (2100) to detect the saturated steam temperature and the thermostat (2121). Both the thermometer (2122) and the thermostat (2121) may be provided, or only one of them may be provided.

[0472] In the iron module (S) of the present invention, the steamer panel (1360) can perform the role of a control unit, and the control panel installed adjacent to the steam generating unit (2100) can also perform the role of a control unit.

[0473] The above control unit may be provided to control the heating heater (2130), the steam valve (2800), the temperature sensor unit (2120), and the steam iron (1300).

[0474] The above control unit can control the steam valve (2800) to open when the temperature of at least one of the thermometer (2122) and the thermostat (2121) reaches a set temperature.

[0475] Meanwhile, the heating heater (2130) is not configured to be constantly submerged in water. Even if the heating heater (2130) is placed inside the steam generator (2100), at least a portion of the area is exposed to the steam when the water is almost evaporated into steam. If the heating heater (2130) is placed outside the steam generator (2100), it is directly exposed to the air. Therefore, the heating heater (2130) has limitations in that the temperature deviation increases as the temperature increases and precise temperature control is impossible.

[0476] Accordingly, the iron module (S) of the present invention can be controlled to open the steam valve (2800) using a pressure switch (2300) when spraying high-temperature, high-pressure steam, and to open the steam valve (2800) using a temperature sensor unit (2120) when spraying relatively low-temperature, low-pressure steam.

[0477] As a result, the iron module (S) of the present invention can control the spraying of a large amount of high-temperature, high-pressure steam or a relatively small amount of low-temperature, low-pressure steam using only one pressure switch (2300).

[0478] Meanwhile, the above heating heater (2130) can measure or control the temperature relatively precisely even when exposed to air or steam below the reference temperature.

[0479] For reference, the above reference temperature can be normally set to 140 degrees Celsius, and it is known that in an area above 140 degrees Celsius, the accuracy of detecting the temperature of the heating heater (2130) or the temperature of the steam by the temperature sensor unit (2120) decreases exponentially.

[0480] Accordingly, if the heating element (2130) of the present invention or the steam generator (2100) is below a reference temperature, the temperature sensor unit (2120) can accurately detect multiple temperature ranges. Accordingly, if at least one set temperature is reached below the reference temperature, the steam valve (2800) can be controlled to open even if the pressure switch does not respond to a specific pressure.

[0481] If there are two set temperatures lower than the above reference temperature, the iron module (S) of the present invention can be controlled to spray steam with a total of three types of temperature, pressure, and spray amount.

[0482] In addition, if there are n set temperatures lower than the reference temperature, the iron module (S) of the present invention can be controlled to inject steam having a total of n+1 types of temperatures, pressures, and injection amounts. The n types of steam are all steam having a relatively small injection amount at a temperature lower than the reference temperature, and one type of steam corresponds to steam having a relatively large injection amount higher than the reference temperature and a specific pressure.

[0483] Meanwhile, the higher the specific pressure, the higher the temperature / pressure of the steam injection. However, it is preferable that the specific pressure be limited by comprehensively considering stability and the maximum required injection amount. However, in any case, the steam at the specific pressure will correspond to steam having a temperature higher than the reference temperature.

[0484] In summary, the iron module (S) of the present invention can be seen as being controlled so that the steam valve (2800) is opened when the temperature of the steam generating unit (2100) reaches a set temperature until the steam generating unit (2100) reaches a reference temperature, and is controlled so that it is opened when the steam generating unit reaches a specific pressure after the reference temperature.

[0485] For example, the reference temperature may correspond to 140 degrees, and the specific pressure may correspond to 4 bar.

[0486] Since the above steam valve (2800) is controlled only by a pressure switch above the reference temperature, it can be controlled to open only when the specific pressure is reached.

[0487] Meanwhile, the set temperature should be at least the temperature at which steam is to be generated, and should be a temperature that can remove basic wrinkles from clothing.

[0488] Additionally, the specific pressure should be at least sufficient to ensure stability, and should be less than the spray amount that would wet the clothing.

[0489] Accordingly, the iron module (S) of the present invention can be operated in a minimum mode or a first mode in which the heating heater (2120) or the steam generator (2100) is heated to an initial temperature at which steam of a minimum temperature condition is generated and the initial temperature is maintained, and a maximum mode or a third mode in which the heating heater (2120) or the steam generator (2100) is heated to a maximum temperature at which steam of a maximum pressure condition is generated and the maximum temperature is maintained.

[0490] The above initial temperature may be lower than the reference temperature.

[0491] When controlled in the minimum mode or the first mode, the minimum injection amount or the first injection amount of steam is generated and injected from the steam generating unit (2100), and when controlled in the maximum mode or the third mode, the maximum injection amount or the third injection amount of steam is generated and injected from the steam generating unit (2100).

[0492] In addition, the iron module (S) of the present invention can be operated in an intermediate mode or a second mode in which the heating heater (2120) or the steam generator (2100) is heated to at least one intermediate temperature that is higher than the initial temperature at which steam is generated under the minimum temperature condition and lower than the maximum temperature at which steam is generated under the maximum temperature condition, and at least one of the intermediate temperatures is maintained.

[0493] The above intermediate temperature may be set below the above reference temperature.

[0494] That is, the steam valve (2800) can be controlled to open when the steam generator (2100) reaches the initial temperature below the reference temperature. In addition, the steam generator (2100) can be controlled to open each time it reaches one or more intermediate temperatures that are higher than the initial temperature and lower than the reference temperature.

[0495] In the following description, it is assumed that the second mode corresponds to one temperature range, but the second mode may be provided in N numbers as long as it is a temperature range higher than the initial temperature and lower than the reference temperature.

[0496] A selection command for selecting whether or not to operate the iron module (S) in the minimum / medium / maximum mode can be input through the input unit of the selection unit (1372) provided in the steam iron (1300).

[0497] The above control unit will drive the heating heater (1320) at the corresponding temperature condition when one of the minimum / medium / maximum modes is determined, and will drive the heating heater (1320) so that the corresponding temperature condition is maintained. In addition, the control unit will open the steam valve (2800) when the corresponding temperature condition is reached.

[0498] When in the above minimum mode, the amount of steam generated from the steam generating unit (2100) is less than the amount of steam generated from the steam generating unit (2100) when in the above maximum mode.

[0499] In addition, the amount of steam generated from the steam generating unit (2100) in the intermediate mode is smaller than in the maximum mode and larger than in the minimum mode.

[0500] Meanwhile, when the power of the steam iron (1300) is cut off or the operation of the steam generator (2100) is terminated, the steam valve (2800) can be controlled to close the cable (1400).

[0501] When the power of the steam iron (1300) is cut off or the operation of the steam generator (2100) is terminated, the steam valve (2800) is closed so that steam is not sprayed to the spray unit (1340).

[0502] In addition, when the power of the steam iron (1300) is cut off or the operation of the steam generator (2100) is terminated, the inside of the steam generator (2100) is filled with high-temperature, high-pressure steam generated in the steam generator in the empty space inside the steam generator.

[0503] For example, the temperature inside the steam generating unit (2100) immediately after use of the steam iron may be higher than the temperature at which water boils, which is the temperature at which steam is generated, and the internal pressure may be about 4 bar.

[0504] Figure 22 illustrates the condensation of steam remaining inside the steam generating unit (2100).

[0505] After a certain period of time, when the temperature inside the steam generating unit (2100) becomes lower than a certain temperature, the steam remaining inside the steam generating unit can be condensed.

[0506] Since the volume of steam is much larger than the volume of condensed water, when the temperature drops below a certain temperature and the steam condenses, the sum of the volumes of steam and water remaining inside the steam generating unit (2100) decreases, so that negative pressure may be formed inside the steam generating unit.

[0507] Accordingly, in order to relieve the pressure, air must be introduced from the outside, but when the steam valve (2800) is closed, air cannot be introduced through the cable (1400) connected to the upper part of the steam generator and communicating with the steam generator, and air introduced from the outside through the vacuum relief valve provided in the water supply structure (2500) is combined with the back surface of the steam generator and air can be introduced through the pump connection pipe (2540) communicating with the water supply structure.

[0508] The steam generating unit (2100) may be provided to accommodate a certain amount of water inside even when the power of the steam iron (1300) is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit, and the drain valve may be controlled to close the drain pipe so that the water remains.

[0509] Accordingly, when the steam valve (2800) is closed, the air introduced through the pump connection pipe passes through the water remaining inside the steam generator (2100) and flows toward the empty space, so that bubbles are created in the water remaining in the steam generator, and noise may be generated when the bubbles burst.

[0510] As a result, in order to block out noise, the steam valve (2800) may need to be opened when the temperature of the steam iron (1300) falls below a certain level after use.

[0511] Figure 23 illustrates the steam condensing when the steam valve (2800) is open.

[0512] When the steam remaining inside the steam generating unit (2100) condenses, the water level of the remaining water inside the steam generating unit may rise and its volume may increase. However, since the volume occupied per unit particle of steam is significantly larger than that of water, the total volume occupied by the steam and water remaining inside the steam generating unit may decrease, and a negative pressure may be formed inside the steam generating unit (2100).

[0513] For example, when the temperature inside the steam generating unit (2100) is 140 degrees and the pressure is 4 bar, if the temperature inside the steam generating unit is lowered to 90 degrees, the volume can be reduced by 600 times.

[0514] When the use of the steam iron (1300) is stopped and the temperature of the steam generator (2100) drops, the steam is condensed and a negative pressure is formed, and the steam valve (2800) is opened, air introduced into the spray unit of the steam iron (1300) can be introduced into the steam generator through the cable (1400).

[0515] Since the above cable can be placed on the upper side of the steam generator (2100), water remaining in the steam generator can be introduced directly into the empty space inside, rather than passing through, thereby preventing noise from being generated due to bubble generation.

[0516] Figure 24 illustrates a cross-section of the steam generating unit (2100) with the steam valve (2800) closed.

[0517] When air is introduced into the steam generator (2100) to relieve the negative pressure or when the air introduced through the pump connection pipe (2540) forms a negative pressure that does not allow bubbles to form, the steam valve (2800) may be closed. At this time, the temperature inside the steam generator may be a temperature at which the steam generator and the outside are in equilibrium or a temperature at which a negative pressure is formed that allows air to be introduced through the pump connection pipe but does not allow noise due to bubble generation to leak out to the outside.

[0518] In summary, immediately after the power of the steam generator (2100) is cut off, high temperature and high pressure steam fills the inside of the steam generator, and when the temperature drops and the high temperature and high pressure steam condenses, the volume inside the steam generator decreases and negative pressure may be generated.

[0519] In order to relieve the above negative pressure, air must be introduced from the outside. However, if air is introduced through the pump connection pipe (2540) connected to the back of the steam generator, it passes through the water remaining inside, which may generate noise due to bubble generation.

[0520] Therefore, air can be introduced through the cable (1400) connected to the steam generator (2100) at a level higher than the remaining water level, thereby preventing noise caused by bubble generation.

[0521] To this end, the steam valve (2800) can be controlled to re-open the cable (1400) when the power of the steam iron (1300) is cut off or the operation of the steam generator is terminated after the steam is generated in the steam generator (2100). That is, the steam valve is closed immediately after the power of the steam iron is cut off or the operation of the steam generator is terminated, and after a certain period of time has elapsed and the steam reaches a temperature at which the steam condenses or a temperature slightly lower than this, the steam valve can be controlled to open the cable (1400).

[0522] Since the volume change may be small at the temperature at which condensation begins, the steam valve can be controlled to open the cable at a temperature lower than this.

[0523] Additionally, the steam valve (2800) can be controlled to close the cable (1400) after a certain period of time has elapsed after the cable has been opened. After a certain period of time, an equilibrium state is reached and no air flows in, but steam or water may flow back through the cable, causing the cable to be closed.

[0524] When steam is generated in the steam generating unit (2100), the power of the steam iron (1300) is cut off or the operation of the steam generating unit (2100) is terminated, and the steam valve (2800) can be controlled to open the cable (1400) after a certain period of time has elapsed, and when air can flow into the steam generating unit (2100) from the steam iron (1300) for a certain period of time while the cable is open, and when the negative pressure is relieved by the inflow of air after a certain period of time or the negative pressure is small enough not to cause noise, the steam valve (2800) can be controlled to close the cable again.

[0525] That is, the steam valve (2800) can be controlled to open the cable (1400) for a certain period of time.

[0526] Meanwhile, the steam valve (2800) can be controlled to close the cable (1400) when steam remains inside the steam generating unit when the power of the steam iron (1300) is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit, and to open the cable again while the steam is condensed inside the steam generating unit.

[0527] When the power of the above steam iron (1300) is cut off and high temperature and high pressure steam remains, the steam valve (2800) can be controlled to close the cable so that steam can be sprayed to the outside through the steam iron.

[0528] In addition, when the power of the steam iron (1300) is cut off and steam is condensed inside the steam generating unit, negative pressure is formed, so external air flows into the inside through the cable, and even if the steam valve (2800) is controlled to open the cable, steam may not be sprayed to the outside.

[0529] Meanwhile, the steam valve (2800) can be controlled to re-seal the cable (1400) after all of the steam has been condensed inside the steam generator (2100).

[0530] When the negative pressure formed in the steam generating unit is completely relieved by external air introduction during the time when all steam is condensed, or when the negative pressure is small enough to not generate noise, the steam valve (2800) can be controlled to close the cable again.

[0531] The steam valve (2800) may be controlled to close the cable until the inside of the steam generating unit reaches a vaporization temperature at which steam is generated or a first temperature lower than the vaporization temperature when the power of the steam iron (1300) is cut off or the operation of the steam generating unit is terminated after the steam is generated in the steam generating unit (2100), and may be controlled to open the cable until the inside of the steam generating unit reaches a second temperature lower than the vaporization temperature or the first temperature.

[0532] When the cable (1400) is opened at the vaporization temperature at which the steam is generated, the steam is sprayed to the outside, so the steam valve (2800) can be controlled to close the cable.

[0533] Meanwhile, at the first temperature lower than the vaporization temperature or the second temperature lower than the first temperature, condensation of the steam occurs, so that negative pressure is formed inside, and the steam valve (2800) can be controlled to open the cable so that external air can flow in through the cable (1400). The first temperature may be a temperature at which negative pressure is formed that causes noise to be generated due to condensation of steam, and the second temperature may be a temperature at which negative pressure is relieved or a temperature at which negative pressure is formed that blocks noise generation.

[0534] The difference between the first temperature and the second temperature can be set to be much larger than the difference between the vaporization temperature and the first temperature.

[0535] Additionally, the second temperature may be set to a temperature higher than room temperature or the temperature outside the cabinet. That is, it may be set to a temperature at which a sound pressure level is formed to block noise generation before equilibrium is achieved.

[0536] Figure 25 illustrates a flow chart for controlling the steam valve (2800) according to the temperature measured by the temperature sensor unit (2120) to relieve negative pressure.

[0537] In the step (S1) where the above steam generating unit (2100) is turned off, the steam valve (2800) can be closed.

[0538] When the steam generator is turned off, the temperature sensor unit (2120) can measure the temperature inside the steam generator, and the control unit that receives the temperature measured by the temperature sensor unit can include a first temperature measurement step (S2) that determines whether the measured temperature is lower than a first temperature. The first temperature may be lower than the vaporization temperature and may be a temperature at which the steam is condensed and a negative pressure is formed.

[0539] The above control unit may proceed with the first temperature measurement step again if the temperature is higher than the first temperature, and may proceed with the steam valve opening step (S3) of opening the steam valve if the temperature is lower than the first temperature.

[0540] The control unit receiving the temperature measured by the temperature sensor unit while the steam valve is open may include a second temperature measurement step (S4) for determining whether the measured temperature is lower than or equal to a second temperature. The second temperature may be a temperature at which steam remaining inside the steam generator (2100) condenses and negative pressure is relieved, or a temperature at which negative pressure is formed to block noise generation.

[0541] The above control unit may proceed with the second temperature measurement step again if the temperature is higher than the second temperature, and may proceed with the steam valve off step (S5) of closing the steam valve if the temperature is lower than the second temperature.

[0542] In conclusion, the control unit can control to open the steam valve (2800) at a temperature where the high-temperature, high-pressure steam inside the steam generator (2100) condenses to form a negative pressure, and to close the steam valve at a temperature where the negative pressure is relieved or the negative pressure is formed to block noise generation by introducing external air. For example, the first temperature may be 90 degrees, and the second temperature may be 50 degrees or lower.

[0543] Through this, the effect of minimizing the noise generated after use of the steam iron (1300) can be obtained.
