[0051] FIG. 1 illustrates the clothing processing device of the present invention.

[0052] The clothing processing device of the present invention may include a cabinet (100) forming an exterior and a clothing receiving section (200) provided to store clothing inside the cabinet (100).

[0053] The clothing receiving section (200) may include a drum (220) for storing clothing inside the cabinet (100). The drum (220) may be provided to rotate the clothing inside the cabinet (100).

[0054] Alternatively, the clothing receiving section (200) may further include a tub (210) for storing water inside the cabinet (100), and the drum (220) may be rotatably provided inside the tub (210).

[0055] The cabinet (100) may include a front panel (110) having an opening (111) communicating with the interior of the drum (220), side panels (150) arranged on both sides of the front panel (110), and a back panel (160) connecting the back of the side panels (150).

[0056] The above front panel (110) may be provided in a plate shape, and a door (112) for opening and closing the opening may be rotatably coupled.

[0057] The above front panel (110) may be equipped with an interface (I) that receives user commands or displays the status of the clothing processing device above the opening (111). At least a portion of the interface (I) may be provided as a touch panel.

[0058] The cabinet (100) may further include an installation panel (120) that is positioned above the opening of the drum (220) and coupled to side panels (150) positioned on both sides.

[0059] The above installation panel (120) may be equipped with a control panel capable of receiving commands to control the clothing processing device or displaying the operating status of the clothing processing device to the outside.

[0060] The above installation panel (120) can be positioned at the rear of the above front panel (110) (110) and can be coupled to the upper part of the front of the above side panel (150).

[0061] The above-described installation panel (120) may have a panel installation part (121) formed therein for fixing the front of the circulation duct (800) described later. The panel installation part (121) may be provided in a groove shape for mounting the rear of the circulation duct (800), or in a hole shape through which a fastening member, which is fastened to the rear of the circulation duct (800), passes.

[0062] The tub (210) may be provided in a cylindrical shape and may be provided with a tub inlet (213) at the front for introducing clothing. The tub inlet (213) may be provided to communicate with the opening of the front panel (110) and may also be provided to communicate with the inside of the drum (220).

[0063] The drum (220) may be provided with a cylindrical metal material with an open front, and may have a through hole on its outer surface so that water and detergent stored in the tub (210) can be introduced or discharged.

[0064] The clothing processing device of the present invention may further include a water supply and drainage unit (400) for supplying or draining water to the tub (210).

[0065] The above water supply and drainage unit (400) may include a water supply unit (410) that supplies water to the tub (210) and a drainage unit (420) that drains the water contained in the tub (210) to the outside of the cabinet (100).

[0066] The above water supply unit (410) may include a water supply valve (411) that receives water from an external water source, a water supply pipe (413) that guides the water supplied from the water supply valve (411) toward the tub (210), and a detergent box (412) that stores detergent and receives water supplied from the water supply valve (411) to supply the detergent to the tub (210).

[0067] The above water supply valve (411) can be connected to the back panel (160) and, if necessary, may be provided in multiple numbers to selectively open and supply water. The above water supply pipe (413) may also be provided in multiple numbers to supply water to at least one of the detergent box (411), the tub (210), and the circulation duct (800) described later.

[0068] The above drainage section (420) may include a drain pipe (421) extending from the lower part of the tub (210) and a drain pump (422) that provides power to discharge water discharged from the drain pipe (421) to the outside of the cabinet (100).

[0069] Additionally, the above-mentioned water supply and drainage unit (400) may further include a circulation unit (430) that recirculates water drained from the drain pipe (421) back into the tub (210).

[0070] The above circulation unit (430) may include a circulation nozzle (431) coupled to the tub inlet (213) to discharge water into the tub (210), and at least one of a circulation hose and a circulation pump that supply water discharged from the drain pipe (421) to the circulation nozzle (431).

[0071] The present invention may further include a base (600) forming the bottom surface of the clothing processing device. The base (600) may be provided to support the cabinet (100) on which the cabinet (100) is seated. Additionally, the base (600) may support electrical components such as the drainage pump (421).

[0072] The clothing processing device of the present invention may further include a support member (500) that supports the tub (210) inside the cabinet (100). The support member (500) may be provided with a plurality of suspensions, one end of which is connected to the tub (210) and the other end of which is connected to the base (600).

[0073] The garment processing device of the present invention may further include a circulation duct (800) capable of circulating air inside the tub (210). The circulation duct (800) may form a flow path for circulating air inside the drum (220) outside the tub (210). Thus, the garment processing device of the present invention may be equipped as a washing machine with a drying function.

[0074] Since components such as a drainage section (420) and a support section (500) are arranged in the lower part of the tub (210), the circulation duct (800) can be placed above the tub (210).

[0075] The clothing processing device of the present invention may further include a heat exchanger (900) for heating air moving through the circulation duct (800). The heat exchanger (900) may include a heat exchanger disposed inside the circulation duct (800) and a compressor (940) disposed outside the circulation duct (800) for supplying high-temperature refrigerant to the heat exchanger.

[0076] The compressor (940) may be positioned below the tub (210). Therefore, a wider space may be secured between the upper part of the tub (210) and the side panel (150) for installing the circulation duct (800). Accordingly, in the clothing processing device of the present invention, the circulation duct (800) may be extended and arranged in the front-rear direction. As a result, the circulation duct (800) extends in the same direction as the extension of the tub (210) and the drum (220), thereby reducing flow resistance and allowing hot air to be supplied evenly inside the drum (220).

[0077] Additionally, by omitting the compressor (940) above the tub (210), the circulation duct (800) can be positioned offset toward either of the two side panels (150) from the top of the tub (210), thereby expanding the cross-sectional area of ​​the circulation duct (800). Accordingly, the clothing processing device of the present invention can circulate a larger flow rate of air to the outside of the tub (210) than when the compressor (940) is positioned above the tub (210).

[0078] The clothing processing device of the present invention may further include an air circulation unit (1000) mounted on a circulation duct (800) to circulate air in the tub (210). Since the compressor (940) is not positioned at the top of the tub (210), the air circulation unit (1000) may be positioned at the rear of the circulation duct (800) to suck in air from inside the tub (210) and supply it into the circulation duct (800).

[0079] Additionally, since the compressor (940) is positioned below the tub (210), the air circulation unit (1000) can utilize the entire space between the top of the tub (210) and the side panel (150). As a result, the air circulation unit (1000) can be positioned with a diameter in the width direction and arranged to rotate around a vertical axis of rotation, thereby enabling the circulation of a more abundant flow rate.

[0080] As a result, in the clothing processing device of the present invention, the compressor (940) is positioned lower than the tub (210), so that a larger flow rate per unit time can circulate through the circulation duct (800), thereby increasing the drying efficiency.

[0081] Figure 2 illustrates the arrangement of the circulation duct and the heat exchanger.

[0082] The tub (210) is provided in a cylindrical shape extending in the front-rear direction, and the cabinet (100) is provided in an internal rectangular shape. Accordingly, in the upper region of the tub (210), more space is secured to the left and right of the center (O) in the width direction of the cabinet (100).

[0083] The above circulation duct (800) may be positioned offset from the center (O) in either the left or right direction. That is, the width-direction center of the above circulation duct (800) may also be positioned offset from the width-direction center (O) of the cabinet in either the left or right direction.

[0084] At this time, a portion of the circulation duct (800) may be arranged to overlap the width-direction center (O) and the height-direction of the cabinet. Additionally, a portion of the circulation duct (800) may be arranged spaced apart from the width-direction center (O) of the cabinet in either the left or right direction. As a result, the cross-sectional area of ​​the circulation duct (800) may be expanded.

[0085] Meanwhile, the compressor (940) may be positioned so as to be offset from the left or right side of the width direction center (O) of the cabinet (100) where the circulation duct (800) is offset.

[0086] For example, the compressor (940) may be placed at the bottom of the circulation duct (800), and the circulation duct (800) and the compressor (940) may be placed so that at least a portion overlaps in the height direction.

[0087] As a result, the vertical distance between the circulation duct (800) and the compressor (940) can be reduced, and the length of the refrigerant pipe (950) connecting the compressor (940) and the heat exchanger placed inside the circulation duct (800) can be reduced. Accordingly, the refrigerant pipe (950) can be arranged in a straight line in the maximum height direction, thereby reducing the flow resistance of the refrigerant and minimizing heat loss occurring in the refrigerant pipe (950).

[0088] Meanwhile, the heat exchanger (900) of the present invention may further include a fixing plate (960) for fixing the refrigerant pipe (950) to the back panel (160) of the cabinet (100). The fixing plate (960) may be provided in the shape of a bracket in which at least one of the back and both sides of the refrigerant pipe (950) is mounted and the height is longer than the width. Thus, the refrigerant pipe (950) can be spaced apart from the tub (210) and supported by the fixing plate (850) and the cabinet (100), and vibrations generated in the tub (210) are prevented from being directly transmitted to the refrigerant pipe (950), thereby enhancing durability.

[0089] Consequently, the compressor (940), the circulation duct (800), the refrigerant pipe (950), and the fixing plate (960) can all be positioned on the left side of the tub (210) or on the right side of the tub (210). Thus, the compressor (940), the circulation duct (800), the refrigerant pipe (950), and the fixing plate (960) can all be easily installed, repaired, and replaced when a single side panel (150) is removed.

[0090] The above circulation duct (800) may include a duct body (810) on which the heat exchanger is seated, and a duct cover (820) coupled to the duct body (810) to shield the duct body (810).

[0091] The above duct body (810) may be provided in a case shape or duct shape with an open top, and the above duct cover (820) may be provided in a plate shape or case shape corresponding to the shape of the duct body (810).

[0092] The above duct body (810) may include a rear connecting part (850) connected to the rear of the tub (210) and communicating with the tub (210), and a front connecting part (840) connected to the front of the tub (210) and communicating with the tub (210).

[0093] The rear connecting part (850) and the front connecting part (840) may be provided in the shape of a duct or pipe through which air can move. The rear connecting part (850) and the front connecting part (840) may be provided with an elastic material. Thus, even if the tub (210) vibrates, the vibration of the tub (210) can be prevented from being transmitted to the duct body (810).

[0094] The above circulation duct (800) may be connected to the tub (210) only at the front connection part (840) and the rear connection part (850), and the duct body (810) may be spaced apart from the tub (210). It may further include a bracket (830) that fixes the position of the rear connection part (850) by fixing the rear connection part (850) to the tub (210).

[0095] The bracket (830) can be positioned at the bottom of the duct body (810) and seated on the tub (210). Thus, even if the duct body (810) is positioned to block the air inlet / outlet of the tub (210), the position of the rear connecting part (850) is fixed through the bracket (830), allowing the air inlet / outlet of the tub (210) and the duct body (810) to be easily connected via the rear connecting part (850).

[0096] FIG. 3 illustrates the structure of the base and the back panel.

[0097] The above base (600) may include a base body (610) that supports the load of the clothing processing device and an installation groove (620) that is recessed in at least one of the left and right sides of the base body (610).

[0098] The above installation groove (620) may be positioned offset to one side of the base body (610) and may be positioned at the rear of the base body (610). The above installation groove (620) may form a space on which the compressor (940) is seated.

[0099] The clothing processing device of the present invention may further include a control unit or a control panel (2000) capable of controlling electrical components placed in the clothing processing device. A circulation duct (800) may be installed on one side of the upper part of the tub (210), and a detergent box or a water storage tank, etc., may be installed on the other side. Accordingly, the control panel (2000) may be installed on the base body (610) and positioned below the tub (210).

[0100] The control panel (2000) may be positioned on the base body (610) spaced apart from the installation groove (620). For example, the control panel (2000) may be positioned offset to the other side of the base body (610). As a result, the control panel (2000) may be prevented from being exposed to heat generated by the compressor (940). Additionally, by positioning the control panel (2000) and the compressor (940) on both lower sides of the tub (210), interference between the control panel (2000) and the compressor (940) and the tub (210) may be prevented.

[0101] The control panel (2000) may include an HP case (2100) that controls the heat exchanger (900) and a main PCB (2200) coupled to the HP case (2100) to control electrical components other than the heat exchanger (900). Since the HP case (2100) has a larger volume and generates more heat than the main PCB (2200), the control panel (2000) may include a panel fan (2300) coupled to one side of the HP case (2100) to cool the HP case (2100). Additionally, the control panel (2000) may further include a noise filter (2300) capable of removing noise from various sensors of the clothing processing device, current supplied from external power, or electrical signals generated from the HP case (2100) and the main PCB (2200). The noise filter (2300) may be mounted on the upper part of the main PCB (2200) to receive current or transmit a current signal.

[0102] The above rear panel (160) may be provided with a panel fixing part (161) on the upper part for fixing the rear of the circulation duct (800). The panel fixing part (161) may be provided in a groove shape for mounting the rear of the circulation duct (800), or in a hole shape through which a fastening member that is fastened to the rear of the circulation duct (800) passes.

[0103] Figure 4 illustrates the structure of the above tub.

[0104] The above tub (210) may include a cylindrical tub body and a tub inlet (213) provided at the front of the tub body through which clothing can be inserted.

[0105] The diameter of the tub inlet (213) may be smaller than the diameter of the tub body. The circulation part (430) may be coupled and fixed to the outer surface of the tub inlet (213).

[0106] The above tub body may be formed by dividing it into a front body and a rear body and joining them together, or it may be molded as a single unit.

[0107] The above tub (210) may further include an air outlet (211) provided at the upper rear of the tub body for discharging air inside the tub (210), and an air inlet (212) provided at the upper part of the tub inlet (213) for receiving air discharged from the circulation duct (800).

[0108] The air outlet (211) may be formed offset to one side from the top of the tub body. By doing so, the air outlet (211) can be extended at a position lower than the top of the tub body, thereby ensuring sufficient space for the air circulation unit (1000) to be installed.

[0109] The air inlet (212) may be formed at the top of the tub inlet (213).

[0110] The above tub (210) may further include a vent hole (215) that is offset to the other side from the top of the tub body and communicates with the outside, and a connecting pipe (216) that communicates the vent hole (215) with the outside of the cabinet (100).

[0111] FIG. 5 illustrates the state in which a circulation duct is installed in the above tub.

[0112] FIG. 5(a) illustrates the tub viewed from the front, and FIG. 5(b) illustrates the tub viewed from the rear.

[0113] The above circulation duct (800) may include a duct body (810) that receives air from an air outlet (211) formed at the upper rear of the tub (210) and discharges air to an air inlet (212) formed at the upper front of the tub (210), and a duct cover (820) that is coupled to the upper part of the duct body (810) and shields the inside of the duct body (810).

[0114] The above duct body (810) can be extended from the rear to the front and can be arranged in a direction corresponding to the front-rear direction of the tub (210) and the drum (220). By doing so, the air resistance flowing through the clothing receiving section (200) and the circulation duct (800) can be reduced.

[0115] The rear connecting part (850) may be provided to connect the rear of the duct body (810) and the air outlet (211), and the front connecting part (840) may be provided to connect the front of the duct body (810) and the air inlet (212).

[0116] The front connecting part (840) may be provided in a square duct shape or in a bellows type. One end or the upper end of the front connecting part (840) may be connected to the duct body (810), and the other end or the lower end may be connected to the air inlet (212).

[0117] The above rear connecting part (850) may be provided in a pipe shape or in a zarab type.

[0118] However, the rear connecting part (850) may be positioned between the duct body (810) and the tub body. Accordingly, the duct body (810) may pressurize the rear connecting part (850) toward the air inlet (212) due to the load. Accordingly, the rear connecting part (850) may be provided such that one end or the upper end is connected to or in close contact with the duct body (810), and the end or lower end is connected to or in close contact with the air inlet (212).

[0119] The above air circulation unit (1000) may be positioned at least partially between the duct body (810) and the duct cover (820), and may be positioned closer to the rear than to the front of the duct body (810).

[0120] The air circulation unit (1000) may be configured to suck in air from the air outlet (211) and supply it into the duct body (810). That is, the air circulation unit (1000) may supply air from inside the tub (210) into the circulation duct (800) at positive pressure.

[0121] A drive unit (300) for rotating the drum (220) may be coupled to the rear of the tub (210). The drive unit (300) may be provided as an outer rotor type.

[0122] FIG. 6 illustrates the positional relationship between the circulation duct of the present invention and the tub.

[0123] The above circulation duct (800) is provided with a resin-based material, and the heat exchanger housed inside may be provided with a metal material. Therefore, the above circulation duct (800) may be susceptible to vibration. In addition, since the above circulation duct (800) has a large self-weight due to the heat exchanger and the air circulation unit (1000), it may vibrate with a frequency and amplitude separate from the vibration of the tub (210). As a result, if the above circulation duct (800) is directly seated on the tub (210), a problem may occur in which the above circulation duct (800) and the above tub (210) collide with each other or, in severe cases, are damaged. Therefore, the above circulation duct (800) may be installed inside the cabinet (100) while maintaining a certain distance from the above tub (210).

[0124] The front connecting part (840) and the rear connecting part (850) are coupled to the tub (210), and the duct body (810) may be positioned such that its lower surface is spaced apart from the tub (210) by a specific distance (h). The front connecting part (840) and the rear connecting part (850) are provided with an elastic material to block vibrations and noise from the tub (210) from being transmitted to the duct body (810).

[0125] FIG. 7 illustrates a specific structural embodiment of the above-mentioned duct body.

[0126] The above duct body (810) may include an inlet duct (811) that receives air from the air outlet (211), a fan housing (812) that extends from the inlet duct (811) and accommodates the air circulation unit (1000), a connecting duct (813) that extends forward from the fan housing (812), an installation duct (814) that extends forward from the connecting duct (813) and installs a heat exchanger, and an exhaust duct (815) that extends forward or downward from the installation duct (814) and discharges air to the air inlet (212). The connecting duct and the installation duct together may be referred to as a moving duct that forms the air flow path of the air passing through the inlet duct.

[0127] The above inlet duct (811) may be positioned above the air outlet (211) and may be positioned overlapping the air outlet (211) in the height direction.

[0128] The above inlet duct (811) may be provided in the shape of a pipe or in the shape of a through hole so that the above rear connecting part (850) can be connected.

[0129] The rear connecting part (850) may have one end or the lower end connected to or in contact with the air inlet (212), and the other end or the upper end connected to or in contact with the inlet duct (811).

[0130] The above-mentioned fan housing (812) may be provided in a circular or spiral shape.

[0131] The above fan housing (812) is provided to be larger than the diameter or area of ​​the above inlet duct (811) so as to secure a space for the air circulation unit (1000) to be installed.

[0132] The above air circulation unit (1000) may be installed in the fan housing (812) to suck in air from the tub (210) and supply it to the heat exchanger.

[0133] The above connecting duct (813) may extend forward from one side of the fan housing (812). The above connecting duct (813) may guide the radial air flow formed by the air circulation unit (1000) forward.

[0134] The above connecting duct (813) may be configured so that its cross-sectional area gradually widens from the rear toward the front. As a result, the air supplied by the air circulation unit (1000) can be evenly distributed while slowing down the flow velocity.

[0135] The above installation duct (814) is provided with a width greater than that of the connecting duct (813) so that the heat exchanger can be seated thereon.

[0136] The above installation duct (814) can form a space in which the evaporator and condenser described later are seated.

[0137] The exhaust duct (815) may be formed with a smaller diameter than the installation duct (814). The exhaust duct (815) may be formed so that its width decreases as it extends forward from the installation duct (814). The end of the exhaust duct (815) may be provided with an area and shape corresponding to the air inlet (212).

[0138] The above exhaust duct (815) is extended forward from the above installation duct (814) with a reduced width and can form an opening at the lower front.

[0139] The above duct body (810) may further include a receiving rib (816) that partitions the fan housing (812) and the connecting duct (813) and accommodates the air circulation section (1000).

[0140] The receiving rib (816) may be provided to discharge air circulating around the inner surface of the fan housing (812) forward. That is, the receiving rib (816) can perform the function of an outlet of the fan housing (812) together with one side of the installation duct (813).

[0141] The clothing processing device of the present invention may further include a fixing part (860) that fixes the front and rear of the circulation duct (800) to the cabinet (100) to separate the circulation duct (800) from the tub (210).

[0142] The above fixing part (860) may include a front fixing part (861) provided at the front of the duct body (810) and fixed to the installation panel (120), and a rear fixing part (862) provided at the rear of the duct body (810) and fixed to the rear panel (160).

[0143] For example, the front fixing part (861) may be provided so that a fastening member, etc., can be attached to the front of the exhaust duct (815).

[0144] Additionally, the front fixing part (861) may be provided in the shape of a protruding projection that protrudes from the front of the exhaust duct (815). The front fixing part (861) may be provided in multiple numbers and arranged spaced apart in the width direction in front of the exhaust duct (815). The front fixing part (861) may be inserted into and seated in the panel installation part (121).

[0145] For example, the rear fixing part (862) may be provided so that a fastening member, etc., can be attached to the rear of the fan housing (812).

[0146] Additionally, the rear fixing part (862) may be provided in the shape of a protruding projection that protrudes from the rear of the fan housing (812). The rear fixing part (862) may be provided in multiple numbers and arranged spaced apart in the width direction at the rear of the fan housing (812). The rear fixing part (862) may be inserted into and seated in the panel fixing part (161).

[0147] FIG. 8 illustrates an example of a structure in which a duct body communicates with a tub.

[0148] The above duct body (810) can be extended from the rear to the front of the tub.

[0149] Additionally, the duct body (810) may be provided with a wide width to accommodate the diameter of the air circulation section (1000) in the width direction and to further expand the cross-sectional area. As a result, the duct body (810) may be arranged to completely overlap the upper part of the air outlet (211) and the upper part of the air inlet (212) in the height direction.

[0150] Since the air inlet (212) is provided in the tub inlet (213), a space can be formed in which the front connecting part (840) is installed in front of the tub (210).

[0151] However, since the air outlet (211) extends upward from the tub body, if the inlet duct (811) is positioned above the air outlet (211), there may be insufficient space for the rear connecting part (850) to be installed or assembled between the air outlet (211) and the inlet duct (811).

[0152] Accordingly, the bracket (830) may be provided to be seated on the upper part of the tub body to connect the rear connecting part (850) to the air outlet (211). The bracket (830) may be coupled to the upper part of the tub body and bring the lower end of the rear connecting part (850) into close contact with the air outlet (211).

[0153] The rear connecting part (850) can be connected to the inlet duct (811) at its upper end while fixed to the bracket (830). The duct body (810) can fix the position of the rear connecting part (850) by pressing the rear connecting part (850) toward the bracket (830).

[0154] The above bracket (830) may include a bracket body (831) that is seated on the tub body and provided in a plate shape, and a coupling hole (832) provided to penetrate the bracket body. The air outlet (211) may be provided protruding upward from one side of the tub body, and the coupling hole may be positioned spaced above the air outlet, and the bracket body may be provided in a plate shape extending in the width direction so as to be seated on the upper surface of the tub body.

[0155] Figure 9 illustrates the internal configuration of a circulation duct.

[0156] The above air circulation unit (1000) can be positioned above the inlet duct (811).

[0157] The above air circulation unit (1000) may include an impeller (1100) that is housed in the fan housing (812) and introduces air inside the tub body, a fan motor (1200) that is mounted on the outside of the duct cover (820) and provides power to rotate the impeller (1100), and a rotating shaft (1300) that passes through the duct cover (820) and connects the fan motor (1200) and the impeller (1100).

[0158] The heat exchanger (900) may include an evaporator (910) seated in the installation duct (814) and a condenser (920) spaced apart from the evaporator (910) toward the exhaust duct (815).

[0159] The above evaporator (910) may be positioned behind the above condenser (920) and close to the air circulation unit (1000), and the above condenser (920) may be connected to the compressor (940) and the refrigerant pipe (950) to receive high-temperature refrigerant.

[0160] When the fan motor (1200) rotates the impeller (1100), the air inside the tub (210) can be introduced into the inlet duct (811) (1). The air introduced into the inlet duct (811) can be introduced into the installation duct (814) along the connecting duct (813) while rotating radially by the impeller (1100). The air introduced into the installation duct (814) can be cooled as it passes through the evaporator (910) to condense moisture, and can be heated as it passes through the condenser (920) (2).

[0161] The air that has passed through the condenser (920) can be discharged through the exhaust duct (815) and then discharged through the air inlet (212) (3 times).

[0162] This process is performed continuously so that the clothing contained in the drum (220) can be dried.

[0163] Figure 10 illustrates the internal structure of a circulation duct.

[0164] Referring to FIG. 10(a), the diameter (w2) of the fan housing (812) may be larger than half the width (w1) of the installation duct. Thus, as shown in FIG. 10(b), the impeller (1100) may be positioned to rotate around a vertical axis of rotation (1300). As a result, more air inside the tub (210) can be drawn into the duct body (810) with greater force and without loss.

[0165] That is, the diameter (R) of the impeller (1100) is provided to be longer than the thickness (H), and the impeller (1100) can be accommodated inside the fan housing (812) such that the diameter (R) is arranged in the width direction and the thickness (H) is arranged in the up-down direction.

[0166] Referring to FIG. 10(a), due to the receiving rib (816), the rear or inlet width (W3) of the connecting duct (813) can be formed to be smaller than the width of the installation duct (W1) and smaller than the diameter (W2) of the fan housing (812). Additionally, the connecting duct (813) can be configured so that its width gradually increases as it faces the evaporator (810).

[0167] Thus, the connecting duct (813) can function as a diffuser that evenly disperses the air supplied from the fan housing (812) in the width direction toward the front.

[0168] The clothing treatment device of the present invention may further include a nozzle part (3000) capable of cleaning the evaporator (910) by spraying water onto the evaporator (910).

[0169] The nozzle section (3000) may be configured to receive water from the water supply section (410) and spray it onto the evaporator (910). The nozzle section (3000) may be arranged to extend in the width direction of the evaporator (910) so as to supply water to the entire rear surface of the evaporator (910).

[0170] The above circulation duct (800) may be provided to discharge water condensed in the evaporator (910) and water sprayed into the evaporator (910) back to the drain (420) or the tub (210).

[0171] The rear surface of the evaporator (910) corresponds to the area where it is first exposed to the air introduced from the tub (210). Accordingly, the nozzle part (3000) can spray water onto the rear of the evaporator (910) to remove foreign matter adhering to the rear surface of the evaporator (910).

[0172] FIG. 11 illustrates a structure for supplying water to the above-mentioned circulation duct.

[0173] The nozzle part (3000) can be positioned between the lower part of the duct cover (820) and the evaporator (910).

[0174] The above water supply unit (410) may include a water supply pipe (413) connected to the above water supply valve (411) to supply water to the above nozzle unit (3000).

[0175] The above water supply pipe (413) is provided in multiple numbers and can extend from the water supply valve (411) toward both ends of the nozzle section (3000). As a result, water can be evenly supplied to the entire width of the nozzle section (3000).

[0176] FIG. 12 shows a front view with the front panel removed.

[0177] Referring to FIG. 12, the tub inlet (213) is provided at the front of the tub (210), and the air inlet (212) may be provided at the upper center of the tub inlet.

[0178] Meanwhile, the air outlet (211) may be provided offset to one side from the rear of the tub (210).

[0179] Additionally, the circulation duct (800) may be provided above the tub (210) and fixed to the installation panel (120). The circulation duct may be provided above the tub, offset to one side where the air outlet (212) is provided, and the circulation duct may be provided to be longer than half the width of the tub. That is, the circulation duct may be provided to encroach upon the center of the tub from one side of the tub.

[0180] Meanwhile, the air inlet (212) and the exhaust duct (815) may be connected by a front connection part (840) to be described later, and the air outlet (211) and the fan housing (812) may be connected by a rear connection part (850) to be described later.

[0181] FIG. 13 illustrates the connection between the circulation duct and the air inlet.

[0182] The connection portion configured to communicate between the tub (210) and the circulation duct (800) may include a front connection portion (840) configured to connect the air inlet (212) and the exhaust duct (815), and a rear connection portion (850) configured to connect the air outlet (211) and the inlet duct (811).

[0183] Referring to FIG. 13, the exhaust duct (815) may protrude forward of the air inlet (212) such that at least a portion of the air inlet overlaps in the vertical direction. This ensures a gap between the exhaust duct and the tub (210), thereby preventing damage to the exhaust duct caused by vibration of the tub.

[0184] Since the exhaust duct (815) protrudes forward from the air inlet (212), the front connecting part (840) may be provided at an angle so as to gradually move forward from the front of the tub (210) as it gets closer to the exhaust duct from the air inlet.

[0185] The above-mentioned front connecting part (840) may be configured to connect the exhaust duct (815) and the air inlet (212) at an angle such that the upper part is positioned further forward than the lower part. This allows the gap with the tub (210) to widen as it goes toward the top, and reduces the frequency of contact with the front connecting part caused by vibrations occurring in the tub, thereby preventing damage to the front connecting part.

[0186] Meanwhile, the front connecting part (840) may be provided to include an upper connecting part (841) coupled to the exhaust duct (815), a lower connecting part (843) coupled to the air inlet (212), and a front connecting pipe (8421) configured to connect the upper connecting part and the lower connecting part.

[0187] The upper coupling portion (841) is provided to surround the outer surface of the exhaust duct (815) and can be press-fitted. For example, the exhaust duct may be provided with a rib protruding outward, and the upper coupling portion may be provided with a groove of a size corresponding to a position corresponding to the rib. In addition, a fastening portion (870) surrounding the outer surface of the upper coupling portion may be provided to improve the coupling force. The fastening portion will be described below.

[0188] The lower coupling portion (843) is provided to surround the outer surface of the air inlet (212) so as to be press-fitted. For example, the air inlet may be provided with a rib protruding outward, and the lower coupling portion may be provided with a groove of a size corresponding to a position corresponding to the rib. In addition, a fastening portion (870) surrounding the outer surface of the lower coupling portion may be provided to improve the coupling force. The fastening portion will be described below.

[0189] Since the above circulation duct (800) is fixed to the above installation panel (120) and the tub vibrates, the front connecting pipe (842) may be provided in the form of a corrugated pipe (8421) with variable length to prevent damage caused by the vibration of the tub. For example, it may be provided as a bellows pipe. The corrugated pipe may be provided to include an extension pipe (84211) that does not contract in the vertical direction and a contraction pipe (84212) that protrudes outward from the extension pipe and is provided to be contractible in the vertical direction.

[0190] The corrugated tube (8421) may be provided at an angle such that as it approaches the upper coupling part (841) from the lower coupling part (843), it moves further away from the tub (210). By doing so, a space between the tub and the corrugated tube is secured, thereby preventing damage to the front connecting part (840) caused by vibration of the tub.

[0191] Additionally, the upper coupling part (841) may be coupled to the discharge duct (815) so as to be parallel to the ground, and the lower coupling part (843) may be coupled to the air inlet (212) so as to be parallel to the ground. In this case, the corrugated pipe (8421) may be provided to be inclined to the ground by varying the length of the contraction pipe (84212).

[0192] Meanwhile, by varying the length of the above-mentioned shrink pipe (84212), the exhaust duct (815) provided in the circulation duct (800) fixed to the cabinet (100) and the air inlet (212) provided in the tub (210) can remain connected even if their relative positions change.

[0193] Additionally, the corrugated tube (8421) can be formed into a curve by cutting the surface adjacent to the tub (210). This minimizes contact with the tub, and even if contact occurs, the curved shape increases the contact area, thereby reducing stress and preventing breakage.

[0194] FIG. 14 illustrates an embodiment of a front connecting pipe from the side.

[0195] Referring to FIG. 14, the corrugated tube (8421) is positioned parallel to the bottom surface and may protrude forward as it approaches the upper coupling part (841) from the lower coupling part (843). That is, it may be provided in a stepped manner that protrudes forward as it goes upward.

[0196] Specifically, the process of providing the extension tube (84211) at the top of the lower coupling part (843), the contraction tube (84212) provided at the top of the extension tube and protruding forward from the extension tube, and the extension tube provided at the top of the contraction tube and protruding forward from the contraction tube is repeated so as to extend to the upper coupling part (841).

[0197] In the case of being provided in a stepped manner, the corrugated pipe (8421) may be provided such that the slope of the rear side is inclined forward more than the slope of the front side, and the corrugated pipe (8421) may be provided such that the length in the front-rear direction becomes shorter as it approaches the upper connecting part (841) from the lower connecting part (843). That is, while the slopes of the front and rear sides of the corrugated pipe are the same, the distance between the rear side and the tub may be provided such that it becomes greater as it goes upward.

[0198] In one embodiment provided in a stepped manner, the extension tube (84211) may be provided in multiple numbers, and the cross-sectional area of ​​the extension tube may be provided such that the lengths in the front and rear directions are equal. That is, they may be provided such that the lengths in the front and rear directions are equal.

[0199] Additionally, the above shrink tubes (84212) may be provided in multiple numbers, and the shrink tubes may be provided such that their cross-sectional area becomes smaller as they approach the upper joint. That is, they may be provided so that their length in the front-rear direction becomes shorter.

[0200] In summary, the lengths of the extension tube (84211) and the contraction tube (84212) may be configured to become shorter towards the top, but the length of the contraction tube may also be configured to become shorter towards the top. This is because the length of the contraction tube is longer than that of the extension tube, so contact with the tub (210) can be prevented even if only the length of the contraction tube is reduced.

[0201] FIG. 15 illustrates a verification unit provided on the side of the exhaust duct and the air inlet.

[0202] The above discharge duct (815) may include a first verification part (8151) that protrudes outward from the outer surface.

[0203] Likewise, the air inlet (212) may include a second verification part (2121) that protrudes outward from the outer surface.

[0204] The first verification part (8151) and the second verification part (2121) are provided on one side and can serve to guide the front connecting part (840) to be connected in the correct direction.

[0205] FIG. 16 illustrates a side view of the state in which the front connecting part is connected to the exhaust duct and the air inlet.

[0206] As described above, since the direction of inclination of the front connecting part (840) is determined, if the front and rear sides of the front connecting part are reversed and connected in the wrong direction, the exhaust duct (815) and the air inlet (212) may not be connected.

[0207] Accordingly, the front connection part (840) may be provided to include a display part (844) positioned at either the front or the rear relative to the center of the side to indicate whether it is the front or the rear. Thus, the user can accurately perform the task of connecting the exhaust duct (815) and the air inlet (212).

[0208] Referring to FIG. 16, the display portion (844) is provided on both the upper coupling portion (841) and the lower coupling portion (843), and is located on the rear side relative to the center. Thus, it can be seen that the surface on which the display portion is provided is the rear side, and the user can connect the rear side to be adjacent to the tub (210).

[0209] Additionally, the clothing processing device of the present invention may include a fastening part (870) provided to secure the front connecting part (840), the discharge duct (815), and the air inlet (212). The fastening part (870) includes a clamp body (871) provided to surround the outer surface of the front connecting part, and a fixing member that connects both ends of the clamp body, and the clamp body may be supported by the indicator part.

[0210] The clamp body (871) is provided to surround the outer surface of the upper coupling part (841) and the lower coupling part (843), and the fixing member (872) may be provided to fix the two opposing ends of the clamp body. The position where the two ends of the clamp body face each other may be where the verification part (8151, 2121) is located. That is, the fixing member may be provided to fix the two ends of the clamp body at a position corresponding to the verification part.

[0211] Additionally, the upper coupling portion (841) may be provided with a first fastening seating portion (8461, see FIG. 16) that protrudes outwardly in a shape corresponding to the first verification portion (8151) in the center, and the fastening seating portion may be provided to accommodate the first verification portion (8151).

[0212] The lower coupling part (843) may be provided with a second fastening seating part (8462, see FIG. 16) that protrudes outwardly in a shape corresponding to the second verification part (2121) in the center, and the second fastening seating part may be provided to accommodate the second verification part (2121).

[0213] The clamp body (871) may be provided in the upper coupling part and the lower coupling part, and both ends of the clamp body (871) may be seated on the first fastening seating part (8461) and the second fastening seating part (8462), respectively, and the two ends may be joined together by a fixing member. That is, it may be provided to surround the outer surface of the upper coupling part and the lower coupling part in the form of a band. Both ends of the clamp body (871) are formed of a through body (872) having a through hole, and the fixing member may pass through the through hole to join both ends of the clamp body.

[0214] Meanwhile, referring to FIG. 15, the first verification part (81511) and the second verification part (81512) may be provided such that their width narrows as they approach the free end, and both sides may be provided with a downwardly convex curve. That is, the first verification part and the second verification part may be provided such that the slope of the tangent increases as they protrude outward.

[0215] Since the first fastening and the second fastening and the second fastening and the second fastening and the first and second fastening and the second fastening and the first and second fastening and the second fastening and the space between the clamp body (871) and the first and second fastening and the

[0216] Thus, the front connecting part (840) can be closely connected to the exhaust duct (815) and the air inlet (212).

[0217] Meanwhile, the above-mentioned display portion (844) may include a first display portion (8441) and a second display portion (8442). The first display portion may be provided to protrude outward from the outer surface of the upper coupling portion (841) and have a free end bent upward, and the second display portion may be provided to protrude outward from the outer surface of the lower coupling portion (843) and have a free end bent upward. By providing a bending surface, the fastening portion (870) can be supported on the bending surface to prevent it from detaching outward.

[0218] Referring to FIG. 16, the first display part (8441) and the second display part (8442) are both provided, but are not limited thereto, and the front coupling part (840) may be provided with at least one of the first display part and the second display part.

[0219] Figure 17 illustrates the side view of the front connection part.

[0220] The above-mentioned front connecting part (840) may be provided with an incline so as to protrude forward as it goes upward.

[0223] FIG. 18 is a perspective view of the front connecting part.

[0224] The first display part (8441) and the second display part (8442) may be provided to protrude further outward than the first fastening and seating part (8461) and the second fastening and seating part (8462), and the shrink tube (84212) may be provided to protrude further outward than the first display part and the second display part.

[0225] FIG. 19 illustrates a connection between a front connection and an exhaust duct, and a fastening part surrounding the front connection.

[0226] The clothing processing device of the present invention may include a fastening part (870) provided to secure the front connecting part (840), the discharge duct (815), and the air inlet (212). The fastening part (870) includes a clamp body (871) provided to surround the outer surface of the front connecting part, and a fixing member (872) that connects both ends of the clamp body, and the clamp body may be supported by the indicator part.

[0227] The clamp body (871) is provided to surround the outer surface of the upper coupling part (841) and the lower coupling part (843), and the fixing member (872) may be provided to fix the two opposing ends of the clamp body. The position where the two ends of the clamp body face each other may be where the fastening seating part (8461, 2121) is located. That is, the fixing member may be provided to fix the two ends of the clamp body at a position corresponding to the fastening seating part and the verification part.

[0228] FIG. 20 illustrates the upper surface of the front coupling portion.

[0229] The above-mentioned front connecting part (840) may include a gripping part (845) extending outward from both sides. A user can grip the gripping part to connect the front connecting part to the discharge duct (815).

[0230] Meanwhile, the gripping part (845) may be provided on the upper part of the front connecting part (840).

[0231] That is, it may be provided on the upper connecting part (841) or on the upper part of the front connecting pipe (842). Since the front connecting part (840) is connected to the exhaust duct (815) while connected to the air inlet (212) and the exhaust duct is located above the air inlet, it may be easier to operate if the gripping part is provided on the upper part of the front connecting part.

[0232] Additionally, the gripping portion (845) may protrude further outward than the shrink tube (84212). This makes it easier for the user to grip.

[0233] Meanwhile, the width of the gripping portion (845) in the front-rear direction may be smaller than the width of the shrink tube (84212) in the front-rear direction. As a result, the gripping portion is spaced further from the tub (210) than the shrink tube, thereby minimizing contact with the tub.

[0234] The present invention may be modified and implemented in various forms, and its scope of rights is not limited to the embodiments described above. Therefore, if a modified embodiment includes the components of the claims of the present invention, it should be considered to fall within the scope of rights of the present invention.
