Description

Technology Field

[0001] The present invention relates to a garment processing device, and more specifically, to a garment processing device capable of performing processes such as sterilization, wrinkle removal, deodorization, and drying of garments by supplying steam and hot air to the garments. Background Technology

[0002] A clothing processing device refers to a washing machine that washes items such as clothing through a washing process and a dryer that dries items through a drying process. Generally, while washing machines and dryers may be provided as separate devices, there are clothing processing devices capable of performing washing and drying simultaneously to overcome space constraints and enhance user convenience.

[0003] For the execution of laundry administration, the garment processing device is equipped with a cabinet, a tub for storing water, a drum providing a space for accommodating the object to be processed, a drive unit fixed to the tub for rotating the drum, a support unit for supporting the tub, a water supply unit for supplying water to the tub, and a drainage unit for draining water from the tub.

[0004] Meanwhile, for the execution of the drying process, the garment processing device is equipped with a circulation path section that draws air from inside the tub and recirculates it to the tub, and a heat exchanger section provided in the path section that sequentially performs dehumidification and heating of the air.

[0005] In other words, among conventional clothing processing devices, there was one equipped with both a washing process device and a drying process device inside the cabinet, allowing the user to selectively perform the washing and drying processes according to their convenience.

[0006] In the conventional clothing processing device according to the above-described technology, components such as a tub, a drum, a circulation channel, and a heat exchanger are arranged in a very complex configuration within a cabinet forming the exterior, in the space between the cabinet and the tub.

[0007] Meanwhile, in the case of the prior art (Korean Patent Publication No. 10-2014-0095788, title: Clothing Processing Device), a hot air supply module (4) for heating and circulating air is provided at the top of the tub, and the hot air supply module (4) includes a circulation path (41, 43, 47) that guides air drawn out from inside the tub (2) to the front surface of the tub (2) (one surface of the tub formed in the direction where the inlet (11) is located), a heat exchanger (45) that exchanges heat with the air flowing along the circulation path, and a blower (49) located between the heat exchanger (45) and the front surface of the tub to circulate the air inside the tub (2).

[0008] Here, in the case of a clothing processing device according to the prior art, a hot air supply module (4) including a circulation channel (41, 43, 47), a heat exchanger (45), a blower (49), etc. is fixedly installed on the upper part of the tub (2).

[0009] Meanwhile, in the case of the tub (2), a drum (3) is provided to be rotatable inside the tub (2), and the drum (3) can be rotated together with the laundry put into it to perform washing / drying of the put-in laundry.

[0010] When the drum (3) described above rotates, vibration may occur in the drum (3) due to the imbalance of the laundry, and the vibration generated in the drum (3) may be transmitted through the tub (2) to a hot air supply module (4) that is fixedly installed on the upper part of the tub (2).

[0011] As described above, in the case of a garment processing device according to the prior art, vibrations generated when the drum (3) rotates can be transmitted to the hot air supply module (4) through the tub (2), and a structure in which such vibrations can be transmitted may have an adverse effect on the durability and performance of the hot air supply module (4).

[0012] Therefore, in order to improve the space utilization of the garment processing device, the arrangement structure of each component placed inside the device is one of the important design considerations, and arranging the components to prevent vibrations generated during drum rotation from being transmitted to other components was also an important design consideration.

[0040] Hereinafter, a clothing processing device according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0041] In describing the present invention, embodiments disclosed in this specification are described in detail with reference to the accompanying drawings. In this specification, identical or similar reference numbers are assigned to identical or similar components even if they are different embodiments, and the description thereof is replaced by the first description. Singular expressions used in this specification include plural expressions unless the context clearly indicates otherwise. Furthermore, in describing embodiments disclosed in this specification, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the embodiments disclosed in this specification.

[0042] First, a clothing processing device according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0043] FIG. 1 is a perspective view showing a clothing processing device according to an embodiment of the present invention.

[0044] 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). 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).

[0045] 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).

[0046] 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).

[0047] The front panel (110) may be provided in a plate shape, and a door (112) for opening and closing the opening (111) may be rotatably coupled thereto. An interface (I) for receiving user commands or displaying the status of a clothing processing device may be installed above the opening (111) on the front panel (110). At least a portion of the interface (I) may be provided as a touch panel.

[0048] 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. The installation panel (120) may be equipped with a control panel (not shown) capable of receiving commands to control the garment processing device or displaying the operating status of the garment processing device externally.

[0049] The above installation panel (120) may be positioned at the rear of the above front panel (110) (110) and may be coupled to the upper front of the above side panel (150). The above 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), and may also be provided with a front fastening hole (122) in the shape of a hole through which a fastening member fastened to the rear of the circulation duct (800) passes.

[0050] The tub (210) may be provided in a cylindrical shape and may be provided with an inlet (213) at the front for introducing clothing. The 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).

[0051] 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.

[0052] 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 (200). The water supply and drainage unit (400) may include a water supply unit (410) for supplying water to the tub (210) and a drainage unit (420) for draining water contained in the tub (210) to the outside of the cabinet (100).

[0053] 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 (200), 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 (200).

[0054] 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.

[0055] 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).

[0056] 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).

[0057] The above circulation unit (430) may include a circulation nozzle (431) coupled to the inlet (213) of the tub to discharge water into the tub (200), 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).

[0058] The clothing processing device of the present invention may further include a base (600) forming a bottom surface. 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).

[0059] The clothing processing device of the present invention may further include a support member (500) that flexibly supports the tub (200) 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 (200) and the other end of which is connected to the base (600).

[0060] 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.

[0061] 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).

[0062] 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 (910, 920) disposed inside the circulation duct (800) and a compressor (940) disposed outside the circulation duct (800) to supply high-temperature refrigerant to the heat exchanger (910, 920).

[0063] The compressor (940) may be positioned below the tub (210). Accordingly, a wider space may be secured between the top of the tub (210) and the side panel (150) for installing the circulation duct (800).

[0064] Accordingly, in the clothing processing device of the present invention, the circulation duct (800) can be arranged to extend 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).

[0065] Additionally, as the compressor (940) is moved from the upper part of the tub (210) to the lower part of the tub (210), the circulation duct (800) can be positioned offset toward one of the two side panels (150) from the top of the tub (210), and the cross-sectional area of ​​the circulation duct (800) can be expanded accordingly.

[0066] Accordingly, the clothing processing device of the present invention can circulate a larger flow of air to the outside of the tub (210) than when the compressor (940) is positioned at the top of the tub (210).

[0067] The clothing processing device of the present invention may further include a circulation fan (1000) mounted in 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 circulation fan (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).

[0068] Additionally, since the compressor (940) is positioned below the tub (210), the circulation fan (1000) can utilize the entire space between the top of the tub (210) and the side panel (150). As a result, the circulation fan (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.

[0069] 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.

[0070] FIG. 2 is a perspective view showing a circulation duct and a heat exchanger of a clothing processing device according to an embodiment of the present invention.

[0071] 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).

[0072] 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.

[0073] 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.

[0074] Meanwhile, the compressor (940) may be positioned so as to be offset from the left or right side of the center (O) in the width direction of the cabinet (100) to the direction in which the circulation duct (800) is offset. For example, the compressor (940) may be positioned at the bottom of the circulation duct (800), and the circulation duct (800) and the compressor (940) may be positioned so that at least a portion overlaps in the height direction.

[0075] As a result, the distance between the circulation duct (800) and the compressor (940) in the vertical direction can be reduced, and the length of the refrigerant pipe (950) connecting the compressor (940) and the heat exchanger (910, 920) placed inside the circulation duct (800) can be reduced. Accordingly, the refrigerant pipe (950) can be arranged in a straight line in the vertical direction as much as possible, so the flow resistance of the refrigerant is reduced and the heat loss generated in the refrigerant pipe (950) can be minimized.

[0076] 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.

[0077] Accordingly, 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.

[0078] 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.

[0079] The above circulation duct (800) may include a duct body (810) on which the heat exchanger (910, 920) is seated, and a duct cover (820) coupled to the duct body (810) to shield the duct body (810).

[0080] 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).

[0081] 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).

[0082] 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).

[0083] 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).

[0084] 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).

[0085] FIG. 3 is a perspective view showing the base and back panel of a clothing processing device according to an embodiment of the present invention.

[0086] 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).

[0087] 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.

[0088] The clothing processing device of the present invention may further include a control unit (not shown) 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).

[0089] 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.

[0090] 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 current supplied from various sensors of the clothing processing device or external power, or from 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.

[0091] 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), and a rear fastening hole (162) in the shape of a hole through which a fastening member fastened to the rear of the circulation duct (800) passes is provided.

[0092] FIG. 4 is a perspective view showing a tub of a clothing processing device according to an embodiment of the present invention.

[0093] The above tub (210) may include a cylindrical tub body (211) and an inlet (214) provided at the front of the tub body (211) into which clothing can be inserted.

[0094] The diameter of the inlet (214) may be smaller than the diameter of the tub body (211). The circulation part (430) may be coupled and fixed to the outer surface of the inlet (214).

[0095] The above tub body (211) may be formed by dividing it into a front body and a rear body and joining them together, or it may be formed as a single unit.

[0096] The above tub (210) may further include an air outlet (212) provided at the upper rear of the tub body (211) through which air inside the tub (210) is discharged, and an air inlet (213) provided at the upper part of the inlet (214) through which air discharged from the circulation duct (800) is introduced.

[0097] The air outlet (212) may be formed offset to one side from the top of the tub body (211). By doing so, the air outlet (212) extends from a position lower than the top of the tub body (211), thereby ensuring sufficient space for the circulation fan (1000) to be installed. The air inlet (211) may be formed at the top of the inlet (211).

[0098] 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 (211) and communicates with the outside, and a connecting pipe (216) that communicates the vent hole (215) with the outside of the cabinet (100).

[0099] FIG. 5 is a perspective view showing a tub and a circulation duct of a clothing processing device according to an embodiment of the present invention.

[0100] FIG. 5(a) illustrates the tub (210) as viewed from the front, and FIG. 5(b) illustrates the tub (210) as viewed from the rear.

[0101] The above circulation duct (800) may include a duct body (810) that receives air from an air outlet (212) formed at the upper rear of the tub (210) and discharges air to an air inlet (213) 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).

[0102] 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.

[0103] The rear connecting part (850) may be provided to connect the rear of the duct body (810) and the air outlet (212), and the front connecting part (840) may be provided to connect the front of the duct body (810) and the air inlet (213).

[0104] The above 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 above 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 (213).

[0105] The above rear connecting part (850) may be provided in a pipe shape or in a zarab type.

[0106] However, the rear connecting part (850) may be positioned between the duct body (810) and the tub body (211). 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).

[0107] The above circulation fan (1000) may be positioned with at least a portion 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).

[0108] The above circulation fan (1000) may be configured to suck in air from the air outlet (212) and supply it into the duct body (810). That is, the circulation fan (1000) can supply air from inside the tub (210) into the circulation duct (800) at positive pressure.

[0109] 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.

[0110] FIG. 6 is a simplified diagram showing the positional relationship between the tub and the circulation duct of a clothing processing device according to an embodiment of the present invention.

[0111] The above circulation duct (800) is provided with a resin-based material, and the heat exchanger (910, 920) 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 (910, 920) and the circulation fan (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), the above circulation duct (800) and the tub (210) may collide with each other or, in severe cases, be damaged. Therefore, the above circulation duct (800) may be installed inside the cabinet (100) while maintaining a certain distance from the tub (210).

[0112] 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).

[0113] FIG. 7 is a perspective view showing a duct body of a clothing processing device according to an embodiment of the present invention.

[0114] The above duct body (810) may include an inlet duct (811) that receives air from the air outlet (212), a fan housing (812) that extends from the inlet duct (811) and accommodates the circulation fan (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 (910, 920), and an exhaust duct (815) that extends forward or downward from the installation duct (814) and discharges air to the air inlet (213).

[0115] The inlet duct (811) may be positioned above the air inlet (813) and may be positioned to overlap the air inlet (813) in the height direction. The inlet duct (811) may be provided in the shape of a pipe or in the shape of a through hole so that the rear connecting part (850) can be connected. One end or the lower end of the rear connecting part (850) may be connected to or in contact with the air inlet (212), and the other end or the upper end may be connected to or in contact with the inlet duct (811).

[0116] The above fan housing (812) may be provided in a circular or spiral shape. The above fan housing (812) may be provided larger than the diameter or area of ​​the inlet duct (811) to secure space for the circulation fan (1000) to be installed. The above circulation fan (1000) may be provided to be seated in the above fan housing (812) to suck in air from the tub (210) and supply it to the heat exchanger (910, 920).

[0117] The above connecting duct (813) may extend forward from one side of the fan housing (812). The connecting duct (813) may guide the radial airflow formed by the circulation fan (1000) forward.

[0118] 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 circulation fan (1000) can be distributed evenly as its flow velocity slows down.

[0119] The above installation duct (814) is provided with a width greater than that of the front end of the above connection duct (813) so that the heat exchanger (910, 920) can be seated thereon. The above installation duct (814) can form a space in which the evaporator (910) and the condenser (920) are seated.

[0120] The exhaust duct (815) may be formed with a smaller diameter than the installation duct (814). The exhaust duct (815) may be formed such 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 (213). The exhaust duct (815) may extend forward from the installation duct (814) with a decreasing width and may form an opening at the lower front.

[0121] 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 a circulation fan (1000). 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).

[0122] 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).

[0123] 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).

[0124] 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).

[0125] Additionally, the front fixing part (861) may be provided with a protruding front fastening boss (862) in the shape of a projection that protrudes from the front of the exhaust duct (815). The front fastening boss (862) may be provided in multiple numbers and may be 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).

[0126] Additionally, 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).

[0127] Additionally, the rear fixing part (862) may be provided with a rear fastening boss (864) having a protruding shape that protrudes from the rear of the fan housing (812). The rear fixing part (862) may be provided in multiple numbers and may be 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).

[0128] Accordingly, the circulation duct (800) can be fixedly supported on the cabinet (100) relatively compared to the tub (210) being flexibly supported by the support member (500) with respect to the base (600).

[0129] That is, the circulation duct (800) is fixed to the cabinet (100), and even if the tub (210) moves due to vibrations generated by the rotation of the drum (220), the vibrations of the tub (210) are reduced at the front connection part (840) and the rear connection part (850), so that the circulation duct (800) can be prevented from moving.

[0130] FIG. 8 is a perspective view showing the communication structure between the duct body and the tub of a clothing processing device according to one embodiment of the present invention.

[0131] The above duct body (810) can be extended from the rear to the front of the tub.

[0132] Additionally, the duct body (810) may be provided with a wide width to accommodate the diameter of the circulation fan (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 in the height direction from the upper part of the air outlet (212) to the upper part of the air inlet (213). Since the air inlet (213) is provided at the inlet (214), a space may be formed in which the front connecting part (840) is installed in front of the tub (210).

[0133] However, since the air outlet (212) extends upward from the tub body (211), if the inlet duct (811) is positioned above the air outlet (212), there may be insufficient space for the rear connecting part (850) to be installed or assembled between the air outlet (212) and the inlet duct (811).

[0134] Accordingly, the bracket (830) may be provided to be seated on the upper part of the tub body (211) to connect the rear connecting part (850) to the air outlet (212). The bracket (830) may be coupled to the upper part of the tub body (211) and the lower end of the rear connecting part (850) may be brought into close contact with the air outlet (212).

[0135] 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).

[0136] FIG. 9 is a partial cross-sectional perspective view showing the flow path structure of a circulation duct of a clothing processing device according to an embodiment of the present invention.

[0137] The above circulation fan (1000) may be positioned above the inlet duct (811). The circulation fan (1000) may include an impeller (1100) that is housed in the fan housing (812) and introduces air inside the tub body (211), a fan motor (1200) that is seated 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).

[0138] 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).

[0139] The above evaporator (910) may be positioned behind the above condenser (920) and close to the circulation fan (1000), and the above condenser (920) may be connected to the compressor (940) and the refrigerant pipe (950) to receive high-temperature refrigerant.

[0140] When the fan motor (1200) rotates the impeller (1100), air inside the tub (210) can be introduced into the inlet duct (811). 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).

[0141] The air passing through the condenser (920) can be discharged through the exhaust duct (815) and then discharged through the air inlet (213). This process is performed continuously so that the clothing contained in the drum (220) can be dried.

[0142] FIG. 10 is a perspective view showing the internal structure of a circulation duct of a clothing processing device according to an embodiment of the present invention.

[0143] 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 (814). 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 (210) with greater force and without loss.

[0144] 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.

[0145] 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).

[0146] 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.

[0147] 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).

[0148] Hereinafter, a circulation duct according to an embodiment of the present invention will be described in detail with reference to FIGS. 11 and 12.

[0149] FIG. 11 is an exemplary diagram showing the connection state of a circulation duct of a clothing processing device according to an embodiment of the present invention, and FIG. 12 is an exploded perspective view showing the connection of a duct body (810) and a duct cover (820) of a circulation duct (800) according to an embodiment of the present invention.

[0150] As described above, the front and rear ends of the circulation duct (800) of the clothing processing device (10) of the present invention are respectively fastened and fixed to the installation panel (120) and the rear panel (160) of the cabinet (100).

[0151] Here, a front fixing part (861) is formed at the front of the duct body (810) constituting the circulation duct (800) to be fastened to a front fastening hole (122) formed in the panel installation part (121) of the installation panel (120), and a rear fixing part (863) is formed at the rear of the duct body (810) to be fastened to the rear fastening part of the rear panel (160).

[0152] Accordingly, the duct body (810) can be fixedly fastened to a separate fastening member between the installation panel and the back panel. Additionally, the duct cover (820) can be detachably coupled to the upper part of the duct body to form the circulation duct (800).

[0153] As described above, the duct body (810) may include an inlet duct (811) that receives air from the air outlet (212), a fan housing (812) that extends from the inlet duct (811) and accommodates the circulation fan (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 (213).

[0154] Here, the inlet duct (811), the fan housing (812), the installation duct (814), and the exhaust duct (815) forming the duct body (810) can be formed integrally by injection molding of the same material.

[0155] Additionally, a sealing groove (894) may be extended and formed on the upper outer surface of the duct body (810) to which a sealing member (not shown) is inserted to form a seal with the duct cover (820) when fastened to the duct cover (820). Meanwhile, the sealing member may be formed along the shape of the outer surface of the duct body (810).

[0156] That is, the sealing groove (894) can be formed along the outer surface of the inlet duct (811), the fan housing (812), the installation duct (814), and the discharge duct (815), and across the entire outer surface of the duct body (810).

[0157] Meanwhile, the duct cover (820) may include a housing cover (821) that shields the fan housing (812), a connection cover (822) that shields the connection duct (813), an installation cover (823) that shields the installation duct (814), and an exhaust cover (824) that shields the exhaust duct (815).

[0158] Here, the housing cover (821), the connecting cover (822), the installation cover (823), and the discharge cover (824) forming the duct cover (820) can be formed integrally by injection molding of the same material.

[0159] A sealing projection (892) may be extended and formed on the lower outer surface of the duct cover (820) to press the sealing member provided in the duct body (810) when connected to the duct body (810). The sealing projection (892) may be formed to extend in correspondence with the shape of the sealing groove (894) formed in the duct body (810).

[0160] Here, the sealing projection (892) may be formed along the outer surface of the housing cover (821), the connecting cover (822), the installation cover (823), and the discharge cover (824) that form the duct cover (820).

[0161] Accordingly, when the duct cover (820) is fastened to the duct body (810), the sealing projection (892) of the duct cover (820) presses the sealing member inserted into the sealing groove (894) of the duct body (810), thereby forming an airtight seal between the duct cover (820) and the duct body (810).

[0162] Here, the duct body (810) is provided so as to be fixedly fastened with the installation panel (120) and the rear panel (160) in contact at the front and rear, respectively, and the duct cover (820) may be detachably provided to the duct body (810) by a separate fastening structure.

[0163] That is, the duct cover (820) must be detachably provided to the duct body (810) for the convenience of installation and maintenance of the circulation fan (1000) and the heat exchanger, etc., installed in the duct body (810).

[0164] Meanwhile, in the case of the above duct body (810), the installation panel (120) and the back panel (160) are fixedly connected in a contact state, so the connection structure of the duct cover (820) connected to the above duct body (810) is necessarily limited.

[0165] The connection between the duct body (810) and the duct cover (820) may be provided with an outer connection part (870) formed on the outer surface of the duct body (810) and the duct cover (820), and an inner connection part (880) formed through the duct body (810) and the duct cover (820) at the front of the duct body (810) and the duct cover (820).

[0166] The outer fastening portion (870) may include a locking hook (874) formed on the outer surface of the duct body (810) and a locking projection (872) elastically extended toward the locking hook (874) on the outer surface of the duct cover (820) corresponding to the position of the locking hook (874).

[0167] Additionally, the internal fastening portion (880) may include an upper fastening portion (880a) formed on the inner side of the discharge cover (824) of the duct cover (820), and a lower fastening portion (880b) formed on the inner side of the discharge duct (824) of the duct body (810) and inserted into the upper fastening portion (880a).

[0168] Meanwhile, as described above, the circulation duct (800) may have an air passage formed from one side of the upper rear of the tub (210) to the other side of the front, and according to this air passage, the flow path from the circulation fan (1000) to the exhaust duct (815) is not formed uniformly and must be formed eccentrically.

[0169] Below, the flow path structure of the above-mentioned circulation duct (800) will be explained in detail with reference to FIG. 13.

[0170] FIG. 13 is a simplified diagram showing the flow path structure of a circulation duct according to an embodiment of the present invention.

[0171] Here, FIG. 13 schematically illustrates a plan view of the duct body (810) among the structures of the circulation duct (800), and the duct cover (820) may be formed to correspond to the shape of the duct body (810). That is, the air flow path of the circulation duct (800) may be formed by the combination of the duct body (810) and the duct cover (820), and the duct body and the duct cover may form the same flow path. Therefore, in describing the air flow path of the circulation duct (800), the duct body (810) will be described in detail, and the description of the duct cover (820) will be omitted.

[0172] As illustrated in FIG. 13, the duct body (810) may include a fan housing (812) in which the circulation fan (1000) is housed, a connecting duct (813) extending forward from the fan housing (812), an installation duct (814) extending forward from the connecting duct (813) in which a heat exchanger (910, 920) is installed, and an exhaust duct (815) extending forward or downward from the installation duct (814) to discharge air to the air inlet (213).

[0173] Meanwhile, the fan housing (812) is formed in a shape that surrounds the circulation fan (1000), and its outer surface may extend toward the connecting duct (813) in a shape having an Archimides curve.

[0174] That is, the outer surface of the fan housing (812) is expanded radially with a constant expansion angle according to the Archimides curve function, with the radius (R1-R2) gradually expanding based on the center of the fan housing (812) (C0, i.e., the center of the circulation fan (1000)), and the center being separated to form a cutoff point (P).

[0175] Accordingly, the outlet side of the fan housing (812) is formed so that the connecting duct (813) is connected based on the cutoff point (P), and the connecting duct (813) can be formed to be connected from the cutoff point (P) and the outer wall (D4) corresponding parallel to the cutoff point (P).

[0176] Meanwhile, one side of the connecting duct (813) may be extended in a manner different from the outer surface of the fan housing (812) being extended by an Archimedes curve function at the outer wall (D4) corresponding to the cutoff point (P).

[0177] That is, the outer wall of the fan housing (812) may be formed by continuously connecting radii (R1-R2) having a center facing the center of the fan housing (812), but the outer wall (D4) of the connecting duct (813) may have a radius (R3) having a center facing the radius (R1-D2) of the fan housing (812).

[0178] Meanwhile, the other side of the connecting duct (813) may have an outer wall (D3) connected to the cutoff point (P), and the other outer wall (D3) of the connecting duct (813) may be formed in a straight line shape, unlike the one outer wall (D4) of the connecting duct (813).

[0179] That is, the above connecting duct (813) may have a curved outer wall (D4) on one side and a straight outer wall (D3) on the other side, and may expand the airflow path of the air moved by the blower fan (1000) in the above fan housing (812).

[0180] Additionally, the discharge port (D1) of the fan housing (812) to which the connecting duct (813) is connected may be formed based on the cut-off point (P), and the discharge port (D2) of the connecting duct (813) to which the installation duct (814) is connected may be formed by one outer wall (D4) and the other outer wall (D3) of the connecting duct (813).

[0181] Meanwhile, in the case of air discharged from the discharge port (D1) of the fan housing (812), it is discharged to the discharge port (D1) of the fan housing (812) by the centrifugal force of the blower fan (100), and the difference in length between one outer wall (D4) and the other outer wall (D3) of the connecting duct (813) affects the air flow velocity, so the air flow velocity and density passing through the connecting duct (813) may become unstable.

[0182] That is, in the case of air discharged from the discharge port (D1) of the fan housing (812), the air flow velocity on one side outer wall (D4) of the connecting duct (813) is formed faster than the air flow velocity on the other side outer wall (D3) of the connecting duct (813) due to the centrifugal force of the blower fan (1000).

[0183] Accordingly, by changing the shape and length of the outer wall (D4) on one side and the outer wall (D3) on the other side of the connecting duct (813), the air flow velocity and density of the air passing through the connecting duct can be stabilized.

[0184] Preferably, the length of one side outer wall (D4) of the connecting duct (813) may be formed to be equal to or longer than the length of the other side outer wall (D3) of the connecting duct (813). Accordingly, by forming the length of one side outer wall (D4) of the connecting duct (813) to be equal to or longer than the length of the other side outer wall (D3) of the connecting duct (813), the air flow velocity can be stabilized.

[0185] Alternatively, the shape of one side outer wall (D4) of the connecting duct (813) may be formed to have a radius (R3) so as to be recessed into the side of the connecting duct, and the other side outer wall (D3) of the connecting duct (813) may be formed in a straight shape to stabilize the air flow velocity.

[0186] Meanwhile, the discharge port (D1) of the fan housing (812) and the discharge port (D2) of the connecting duct (813) may have a ratio of 4:6. That is, air passing through the discharge port (D1) of the fan housing (812) moves to the installation duct (814) through the discharge port of the connecting duct (813), and if the size of the discharge port (D2) of the connecting duct (813) is relatively smaller than the discharge port of the fan housing (812), instability in the flow velocity and a decrease in flow velocity of the air passing through the connecting duct (813) occur.

[0187] Accordingly, by forming the discharge port (D1) of the fan housing (812) and the discharge port (D2) of the connecting duct (813) to have a ratio of 4:6, the airflow velocity passing through the connecting duct (813) can be stabilized and the velocity can be prevented at the same time.

[0188] Additionally, the shape and length of one outer wall (D4) and the other outer wall (D3) of the connecting duct (813) may be formed differently, and in this case, the center (C1) of the discharge port (D1) of the fan housing (812) and the center (C2) of the discharge port (D2) of the connecting duct may be formed to be spaced apart from each other by a certain distance (G0).

[0189] As described above, preferred embodiments of the present invention have been described in detail; however, a person skilled in the art to which the present invention pertains will be able to modify the present invention in various ways without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, future modifications to the embodiments of the present invention will not depart from the technology of the present invention.
