[0030] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. In this specification, identical or similar components are given identical or similar reference numerals even in different embodiments, and the description thereof is replaced with the first description. The singular expression used in this specification includes plural expressions unless the context clearly indicates otherwise. In addition, when describing the embodiments disclosed in this specification, if a detailed description of a related known technology is judged to obscure the gist of the embodiments disclosed in this specification, the detailed description thereof will be omitted. In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification should not be construed as being limited by the attached drawings.

[0031] Figure 1 illustrates the appearance of the clothing treatment device of the present invention.

[0032] Referring to FIG. 1, the cabinet (100) may form an exterior and include an opening at the front through which clothing is inserted. A first case (200) may be provided within the cabinet (100) to hold clothing inserted through the opening. The first case (200) 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, heated air, steam, or moisture.

[0033] The first case (200) may be provided with a height greater than its width. As a result, the clothing may be accommodated within the first case without being folded or wrinkled.

[0034] In addition, it may include a second case (300) that is rotatably coupled to the cabinet (100) to open and close the opening and includes an open surface through which clothes are inserted in the front.

[0035] The second case (300) may be formed of a plastic resin series like the first case (200), and may be formed of a reinforced plastic resin series that does not deform even when exposed to air at a temperature higher than room temperature, heated air, steam, or moisture. In addition, it may be formed in a shape corresponding to the first case. That is, the height may be formed to be longer than the width. However, the height of the second case may be higher than the height of the first case, and the width of the second case may be wider than the width of the first case. As a result, the first case (200) may be shielded by the second case (300).

[0036] In addition, a door may be provided that is rotatably coupled to the second case (300) and opens and closes the open surface. That is, the second case opens and closes the open surface of the first case (200), and the door can open and close the open surface of the second case.

[0037] Additionally, the door may be long enough to open and close not only the open surface of the second case but also the open surface of the cabinet. Accordingly, it can cover the machine room, which includes a water tank and a drain tank, etc., provided at the bottom of the second case. The machine room will be described later.

[0038] Additionally, the door may be made of a transparent material to allow the interior of the second case to be seen. Accordingly, the condition of clothing placed in the second case can be checked even when the second case is closed.

[0039] In addition, the clothing treatment device of the present invention may include a machine room (500) including a suction unit (510) positioned at the lower portion of the first case (200) to suck in air inside the first case, a heat exchange unit (520) positioned in front of the suction port to dry the sucked air at a high temperature, and a supply unit (530) positioned in front of the heat exchange unit to supply air that has passed through the heat exchange unit to the first case and the second case (300), and the first case and the second case may be provided so that they can simultaneously receive the air from the supply unit. A detailed structure will be described later.

[0040] Figures 2 and 3 illustrate the flow of air inside the clothing treatment device of the present invention.

[0041] Referring to FIG. 2, the first case (200) may include a first supply hole (210) communicating with the supply unit (530). The first supply hole may be provided through the bottom surface of the first case.

[0042] Additionally, the second case (300) may include a second supply hole (310) communicating with the supply unit (530). The second supply hole may be provided through the bottom surface of the second case.

[0043] The first supply hole (210) and the second supply hole (310) may be provided to face the supply unit (530). That is, the open surface of the supply unit may be provided to accommodate both the first supply hole and the second supply hole.

[0044] Accordingly, the high-temperature dry air discharged through the supply unit (530) can be supplied to both the first supply hole (210) and the second supply hole (310). Accordingly, air can be supplied to both the first case and the second case simultaneously in one machine room (500).

[0045] Additionally, the first case (200) may be provided with a first communication hole (230) penetrating the upper surface of the first case. Air may be introduced from the second case through the first communication hole.

[0046] In addition, the first case (200) may include a discharge hole (220) facing the suction part (510) and penetrating the lower surface of the first case. The air flowing inside the first case may be sucked into the suction part (510) through the discharge hole.

[0047] Since the first communication hole is provided on the upper surface of the first case and the exhaust hole is provided on the bottom surface of the first case, the air can flow from the upper surface to the lower surface. Accordingly, even when the clothing is placed facing forward, the area of ​​contact between the clothing and the air can be increased. In addition, since the upper surface of the cabinet (100) and the upper surface of the first case (200) can be provided to be spaced apart from each other, providing the first communication hole on the upper surface can facilitate the installation of a connecting passage described later.

[0048] Meanwhile, the second case (300) may include a second communication hole (320) positioned above the upper surface of the first case (200) and penetrating the rear surface of the second case. Air passing through the second supply hole may move upwards of the second case and into the interior of the first case through the second communication hole.

[0049] In addition, the second case (300) may include a connecting passage (340) provided to connect the first communication hole and the second communication hole. The connecting passage may be provided in the space between the cabinet (100) and the first case (200).

[0050] In addition, since the second case (300) is rotatably coupled to the cabinet (100), when the second case rotates to open the opening, the distance between the first communication hole (230) and the second communication hole (320) increases, so the connecting passage (340) may be provided in the form of a corrugated pipe so that its length can be shortened and then lengthened.

[0051] The air can move from the suction unit to the supply unit because a pressure difference occurs between the supply unit and the suction unit due to a blower fan provided between the suction unit (510) and the supply unit (530) in the machine room (500).

[0052] In addition, since the pressure of the first supply hole (210) and the second supply hole (310) is greater than the pressure of the discharge hole (220), the air can move from the first supply hole and the second supply hole to the discharge hole.

[0053] The air supplied from the supply unit (530) through the second supply hole (310) moves upwards of the second case (300), passes through the second communication hole (320) and the connection path (340), and is discharged from the first communication hole (230) to the first case (200). The air inside the first case passes through the discharge hole (220), is sucked into the suction unit (510), passes through the heat exchange unit (520), and is directed to the supply unit (530) to circulate.

[0054] Likewise, the air supplied from the supply unit (530) through the first supply hole (210) moves toward the upper surface of the first case (200), circulates inside the first case, passes through the discharge hole (220), is sucked into the suction unit (510), passes through the heat exchange unit (520), and is circulated toward the supply unit (530).

[0055] That is, the air discharged from the supply unit (530) passes through the first supply hole (210) and the second supply hole (310) and heads toward the first case (200) and the second case (300), and the air is sucked back into the suction unit (510) through the discharge hole (220) and passes through the heat exchange unit (520) and can flow toward the supply unit.

[0056] The above circulation can be achieved by a blower fan provided between the suction unit (510) and the supply unit (530).

[0057] Figure 3 shows the machine room of the garment treatment device of the present invention.

[0058] The above machine room (500) can be placed at the bottom of the first case (200).

[0059] The above machine room may include the suction unit (510) that sucks in air inside the first case through the discharge hole (220), the heat exchange unit (520) that is positioned in front of the suction unit and dries the sucked air at a high temperature, and the supply unit (530) that is positioned in front of the heat exchange unit and supplies air that has passed through the heat exchange unit to the first case (200) and the second case (300).

[0060] More specifically, the machine room (500) may be arranged to be separated or partitioned from the first case (200) and the second case (300), but may be provided to communicate with the first case (200) and the second case (300).

[0061] The above-mentioned machine room (500) can be placed below the first case (200) and the second case (300). Thus, when hot air having a low specific gravity is supplied to the first case (200) and the second case (300), the hot air can be naturally supplied to the clothing.

[0062] The above machine room (500) may include a circulation duct that circulates air inside the first case (200) and the second case (300), and a heat exchange unit (520) that includes a plurality of heat exchangers that are arranged on the circulation duct to cool and condense the air and heat the air.

[0063] The above machine room (500) may be equipped with a heat pump system including a compressor that is connected to the plurality of heat exchangers and can compress a refrigerant that cools or heats the air.

[0064] Additionally, a blower fan may be provided to circulate the air.

[0065] Meanwhile, the machine room (500) may also be equipped with a steam supply unit capable of supplying steam to the inside of the first case (200).

[0066] The above steam supply unit may be configured to heat water to generate steam. Thus, clothing contained within the first case may be exposed to hot air and steam, thereby undergoing deodorization, sterilization, and wrinkle removal.

[0067] The steam supply unit may include a water tank located below the supply unit and detachably provided to store water, a steam generator (542) that is connected to the water tank and receives the water and heats it to generate steam, and a steam nozzle (543) that is connected to the steam generator and is located on the side of the supply unit and sprays steam generated in the steam generator.

[0068] Additionally, it may include a drain tank that collects condensed water during the process of dehumidifying the air while passing through the heat exchanger.

[0069] The above water supply tank and drain tank may be detachably installed below the supply unit (530). Accordingly, even if the garment treatment device of the present invention is not placed near a water source or drain, the user can detach and transport the water supply tank and drain tank whenever necessary.

[0070] The above water supply tank and drain tank can be arranged in parallel along the width direction of the machine room (500).

[0071] In addition, the machine room (500) may further include a drawer for storing items necessary for managing the clothing. The drawer may be provided so as to be withdrawable from the machine room (500), and may be provided with a space therein for storing items such as an iron.

[0072] Meanwhile, the supply unit (530) may be provided so that its area increases as it goes upward. As the area of ​​the supply unit increases as it goes upward, it may be easy to supply the air simultaneously to the first supply hole (210) and the second supply hole (220).

[0073] In addition, the supply unit (530) may include a partition wall (531) that is provided to divide the supply unit into front and rear sections so that the air can be easily supplied by dividing it into the first supply hole (210) and the second supply hole (310).

[0074] That is, based on the partition wall (531), air directed toward the rear of the partition wall can be supplied to the first case (200) through the first supply hole (210), and air directed toward the front of the partition wall can be supplied to the second case (300) through the second supply hole (310).

[0075] It is preferable that the above-mentioned bulkhead (531) be provided at a position corresponding to the boundary between the second case (300) and the first case (200).

[0076] The above bulkhead (531) may be provided with the same material as the above supply unit (530), but 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, steam, or moisture.

[0077] FIG. 4 illustrates a process in which air supplied to the second case (300) through the second supply hole (310) passes through the first case (200) and is sucked into the suction unit (510), and a process in which air supplied to the first case (200) through the first supply hole (210) is sucked into the suction unit (510).

[0078] The air supplied from the supply unit (530) to the second case (300) through the second supply hole (310) can move upwards of the second case, pass through the second communication hole (320), and head toward the first case (200) through the connecting passage (340).

[0079] Additionally, the air can be supplied from the supply unit (530) to the first case (200) through the first supply hole (210).

[0080] Accordingly, all of the air supplied from the supply unit (530) is directed into the first case (200) and can be sucked into the suction unit (510) through the discharge hole (220) provided in the first case and circulated.

[0081] Figure 5 illustrates controlling the flow of air by a valve provided in the second case in the clothing treatment device of the present invention.

[0082] The second case (300) may include a valve that is rotatably coupled to the outer surface of the second case to open and close the second communication hole (320). The valve may be rotatably coupled to the outer surface of the rear surface of the second case.

[0083] Accordingly, the valve (330) can be rotated by air flowing from the second case (300) to the first case (200) to open the second communication hole (320), and when the air is not supplied, the second communication hole can be blocked by the valve.

[0084] Conversely, in order to prevent the valve from rotating into the second communication hole (320) by the rear surface of the second case (300), the valve may be provided with a wider width than the second communication hole. Accordingly, the valve may be supported on the outer surface of the second communication hole and may rotate into the second communication hole by air or steam flowing from the first case (200) to the second case (300), thereby preventing the second communication hole from being opened, and thus the second communication hole may be shielded.

[0085] That is, the valve (330) allows air to move from the second case (300) to the first case (200), but can block air or steam from moving from the first case (200) to the second case (300). However, in this case, the connecting passage (340) should be provided to be larger than the area of ​​the valve.

[0086] Meanwhile, a control unit that controls a motor connected to the valve is provided to control the flow of air.

[0087] The above valve is an example, and any configuration that allows air to flow in only one direction is acceptable.

[0088] Figure 6 illustrates the flow of steam supplied from the steam supply unit.

[0089] The steam nozzle of the garment treatment device of the present invention may be positioned at the rear of the second case and provided to face the first supply hole so as to supply steam to the first case.

[0090] The second case (300) may contain moisture-sensitive products. Therefore, it may be necessary to block the supply of steam to the second case.

[0091] Accordingly, the steam nozzle (543) of the garment treatment device of the present invention may be installed in the machine room (500) so as to communicate only with the first supply hole (210) and not with the second supply hole (310). That is, it may be located on the side of the supply unit (530), and may be installed closer to the first case at the boundary between the second case (300) and the first case (200). In addition, it may be located behind the partition wall (531).

[0092] Therefore, the steam discharged through the steam nozzle (543) can be supplied to the first case (200) through the second supply hole (310).

[0093] In addition, when the steam is supplied, air may not be supplied from the supply unit (530). Therefore, the valve (330) blocks the second communication hole (320), and since the valve does not rotate due to the steam, it cannot move to the second case through the second communication hole.

[0094] Accordingly, the steam flowing inside the first case (200) can be sucked into the suction unit (510) through the discharge hole (220).

[0095] Figure 7 illustrates a hanger section on which clothes are placed in the clothes treatment device of the present invention.

[0096] The garment treatment device of the present invention may include a hanger unit (600) that is coupled to the upper surface of the first case and is provided to support a hanger on which garments are placed. When the garments are placed on the hanger unit (600), the garments may be placed in a state of floating in the air within the first case (200).

[0097] Since the garment treatment device of the present invention is equipped with the second case (300), it may be necessary to have the garments face forward in order to maintain the amount of garments that can be hung while making the length of the cabinet (100) in the front-back direction the same as that of a cabinet of a conventional garment treatment device. Accordingly, the hanger section (600) may extend forward from the rear of the first case (200).

[0098] Since the above clothing is directed forward, if the air supplied from the supply unit (530) is directed from the front to the rear, the flow of the air may not be smooth.

[0099] Accordingly, the clothing treatment device of the present invention can guide air moving from the second case (300) to the first case from the upper side downward by providing the first communication hole (230) on the upper surface of the first case (200). This can increase the area of ​​contact between the clothing and the air and facilitate the flow of air.

[0100] The present invention may be implemented in various modified forms, and the scope of the invention is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
