Description

Garment processing equipment

[0001] The present invention relates to a clothing treatment device, and more specifically, to a clothing treatment device having a filter cartridge for filtering out foreign substances in the air.

[0002] In general, a clothes dryer is a device that places laundry that has been washed and dehydrated into the drum (or tub) of the dryer and supplies hot air into the drum to evaporate the moisture in the laundry and dry the laundry.

[0003] The air that evaporates the moisture from the laundry in the drum of the clothes dryer contains the moisture from the laundry inside the drum, becoming hot and humid air. At this time, dryers can be classified based on the method of handling this hot and humid air. That is, they can be divided into condensation dryers, which condense the moisture contained in the hot and humid air by allowing heat exchange in a heat exchanger while the hot and humid air circulates rather than being discharged outside the dryer, and exhaust dryers, which directly discharge the hot and humid air that passes through the drum to the outside.

[0004] Meanwhile, the air exiting the drum after drying the object may contain foreign substances, such as lint, from the object. These foreign substances can cause malfunctions in the mechanical components of the clothes dryer or, if released outside, contaminate the outside air. Therefore, the air passing through the drum must be filtered to remove foreign substances.

[0005] Typically, a filter is provided at the front of the drum to remove foreign substances contained in the air passing through the drum. However, with continuous use of the dryer, foreign substances such as lint accumulate in the filter.

[0006] When these foreign substances accumulate to a certain level, they impede airflow, requiring regular cleaning. This filter is cleaned by the user after the drying cycle ends, removing the filter from the dryer, removing any foreign substances, and then reattaching it to the dryer.

[0007] However, since cleaning as described above must be done by hand by the user, it is not only cumbersome, but also cannot be done every time the product is dried, which may cause problems such as air flow being gradually obstructed before cleaning, preventing the sufficient amount of air required for drying from being secured.

[0008] To address these issues, a filter device has been developed that automatically and continuously cleans the filter in addition to regular filter cleaning. Meanwhile, Korean Patent Publication No. 10-2011-0123346 (published on November 15, 2011, titled "Dryer," hereinafter referred to as "prior art") discloses a filter assembly including a filter cleaning unit for automatically cleaning the filter.

[0009] These filter cleaners are composed of a brush that comes into contact with the filter to clean lint, and a drive motor for driving the brush. As the brush rotates by the rotational force of the drive motor, foreign substances on the filter surface are removed by dropping them.

[0010] However, in the prior art, the filter cleaner is mounted at the center of a symmetrical filter. Accordingly, the filter cleaner rotates along a circular orbit or is driven along a symmetrical reciprocating orbit.

[0011] However, dryers typically feature a drum at the center of the body, with the blower fan, which drives airflow through the drum, mounted on the side of the body. This is to minimize the dryer's volume while efficiently arranging internal components.

[0012] Here, the filter unit is installed between the drum and the blower fan on the diaphragm. Therefore, air containing foreign substances discharged from the drum and passing through the filter is affected by the blower fan. As previously mentioned, the blower fan is positioned on the side of the drum to maximize the space efficiency of the dryer. Therefore, air passing through the filter is also affected by the blower fan, causing it to flow biased toward one side.

[0013] Therefore, in the case of conventional symmetrical filters, the accumulation of foreign substances such as lint is concentrated in the center of the filter, toward the blower fan. In particular, in the case of auto filters, foreign substances removed from the filter surface by the brush and accumulated on the bottom are also concentrated in one side, leaving a lot of free space on the other side.

[0014] That is, in the case of conventional symmetrical filters or auto filters, since the position of the blower fan is not taken into consideration, the filter cannot be used efficiently and must be cleaned early, or there is a problem of the wind volume being reduced early.

[0015] The present invention has been devised to solve the above-mentioned problems, and its purpose is to provide a clothing treatment device capable of securing a flow path in a filter unit by compressing lint loaded in a filter unit that filters lint generated during clothing treatment within the filter unit.

[0016] In addition, the present invention has been devised to solve the above-mentioned problems, and the purpose of the present invention is to provide a clothing treatment device capable of reducing the number of times the filter part is cleaned by compressing the lint loaded in the filter part that filters the lint generated during the treatment of clothing inside the filter part.

[0017] In addition, the present invention has been devised to solve the above problems, and its purpose is to provide a clothing treatment device capable of squeezing lint inside the filter part by improving the structure of the filter part that filters lint generated during clothing treatment.

[0018] In order to achieve the above object, an embodiment of the present invention provides a clothing treatment device, comprising: a cabinet having an opening at the front; a drum having an inlet communicating with the opening and accommodating clothing; a driving unit accommodated inside the cabinet and rotating the drum; a circulation duct circulating air discharged from the inlet outside the drum and resupplying the air to the drum; a heat supply unit installed inside the circulation duct and including one or more heat exchangers for condensing moisture from the air or heating the air; a mounting unit configured to communicate the inlet and the circulation duct and guiding air inside the drum to the circulation duct; and a first filter provided on the mounting unit and filtering foreign substances from the air flowing into the mounting unit.

In addition, the mounting portion (138) may be provided to allow air discharged from the drum (200) to flow in, and the introduced air may pass through the mounting portion (138) and move to the circulation duct (300).

[0064] Meanwhile, the second support member (140) may be provided to include a second fixed body (141) fixed inside the cabinet (100), and a second support body (145) provided on the second fixed body (141) and inserted into the rear surface of the drum body (210). The second support member (140) is provided with an air inlet (148) that penetrates the second fixed body (141) and connects the inside of the drum body (210) with the inside of the cabinet (100). In this case, a circulation duct (300) may be provided to connect the mounting member (138) and the air inlet (148).

[0065] In addition, the first support member (130) may be provided with a first roller (139) that rotatably supports the circumference of the drum body (210), and the second support member (140) may be provided with a second roller (149) that rotatably supports the circumference of the drum body.

[0066] Meanwhile, the drum body (210) can be rotated by a rotational force transmitted from a driving unit (280). The driving unit (280) can include a motor (230) fixed inside the cabinet (100), a pulley (250) rotated by the motor, and a belt (270) connecting the circumference of the pulley (250) and the circumference of the drum body (210).

[0067] The circulation duct (300) may be provided to include an exhaust duct (310) connected to the mounting portion (138), a supply duct (330) connected to the air inlet (148), and a connecting duct (350) connecting the exhaust duct and the supply duct.

[0068] The heat exchange unit (400) may be equipped with various devices capable of sequentially dehumidifying and heating the air introduced into the circulation duct (300). For example, the heat exchange unit (400) may be equipped with a heat pump system.

[0069] Meanwhile, the heat exchange unit (400) may include a fan (490) that moves air along the circulation duct (300), a first heat exchanger (evaporator, 41) that removes moisture from air flowing into the circulation duct (300), and a second heat exchanger (condenser, 43) that is provided inside the circulation duct (300) and heats air that has passed through the first heat exchanger (410).

[0070] Here, the fan (490) may be provided to include an impeller (491) provided inside the circulation duct (300) and an impeller motor (493) that rotates the impeller (491). The impeller (491) may be provided in any of the exhaust duct (310), the connection duct (350), and the supply duct (330). In the present invention, a case where the impeller (491) is provided in the supply duct (330) will be described as an example.

[0071] Meanwhile, the first heat exchanger (410) may be provided with a plurality of metal plates arranged along the width direction of the connecting duct (350) or the height direction of the connecting duct, and the second heat exchanger (430) may be provided with a plurality of metal plates arranged along the width direction of the connecting duct or the height direction of the connecting duct. The first heat exchanger (410) and the second heat exchanger (430) are sequentially arranged in the direction from the exhaust duct (310) toward the supply duct (330) inside the connecting duct (350), and are connected to each other through a refrigerant pipe (480) that forms a circulation path of the refrigerant.

[0072] Here, the refrigerant moves along the refrigerant pipe (480) by a compressor (450) located outside the circulation duct (300), and the refrigerant pipe (480) is equipped with a pressure regulator (470) that regulates the pressure of the refrigerant that has passed through the second heat exchanger (430).

[0073] Meanwhile, the first heat exchanger (410) is a means for cooling the air and evaporating the refrigerant by transferring the heat of the air introduced into the exhaust duct (310) to the refrigerant. The second heat exchanger (430) is a means for heating the air and condensing the refrigerant by transferring the heat of the refrigerant that has passed through the compressor (450) to the air. In this case, when the moisture contained in the air passes through the first heat exchanger (410), it will collect on the bottom surface of the connecting duct (350) along the surface of the first heat exchanger (410). Here, in order to collect the water removed from the air passing through the first heat exchanger (410), a water collecting part (360) is provided at the bottom of the circulation duct (300).

[0074] Meanwhile, the water collected in the water collection unit (360) may be collected in a reservoir (600) so that it can be discharged in batches later. The reservoir (600) may be provided to include a storage body (620) that is detachably mounted on the cabinet (100) and provides a space for storing water, and an inlet (622) that is provided to penetrate the storage body (620) and allows water discharged from the reservoir supply pipe (510) to be introduced into the storage body (620).

[0075] In addition, the storage body (620) may be provided as a drawer-type tank that is withdrawn from the cabinet (100), in which case the front panel (110) of the cabinet must be provided with a reservoir mounting hole into which the storage body (620) is inserted. A panel (610) is fixed to the front surface of the storage body (620), and the panel (610) may be provided to be detachably coupled to the reservoir mounting hole (138a) to form a part of the front panel (110).

[0076] Meanwhile, the panel (610) may further be provided with a groove (611) into which the user's hand is inserted. In this case, the panel (610) will also function as a handle for withdrawing the storage body (620) from the cabinet (100) or inserting it into the cabinet (100).

[0077] Here, the inlet (622) may be provided to receive water discharged from a nozzle (623) fixed to the cabinet (100). The nozzle (623) may be fixed to the upper panel (125) of the cabinet so as to be positioned above the inlet (622) when the storage body (620) is inserted into the cabinet (100).

[0078] Meanwhile, in order to minimize foreign substances (hereinafter referred to as “lint”) discharged from the drum body (210) from accumulating on the first heat exchanger (410) and the second heat exchanger (430), the clothing treatment device (1) may further be equipped with a filter unit (700) that filters lint in the air.

[0079] The filter unit (700) is a means for filtering air flowing into the exhaust duct (310) from the drum body (210), and can be detachably inserted into the exhaust duct (310) through the mounting unit (138).

[0080] Below, the mounting status of the filter unit will be described in detail with reference to the attached drawings 3 and 4.

[0081] Fig. 3 is a perspective view showing the mounting state of a filter unit according to the present invention, Fig. 4 is a perspective view showing a filter unit according to the present invention, and Fig. 5 is an exploded perspective view showing a filter unit according to one embodiment of the present invention.

[0082] As shown in Fig. 3, the filter unit (700) is provided so as to be insertable into the mounting unit (138) formed at the lower portion of the connecting body (137) of the first support unit (130). Here, the mounting unit (138) may be provided so as to penetrate the connecting body (137) and communicate with the circulation duct (300).

[0083] Meanwhile, the mounting portion (138) may be provided to connect the inlet (133) and the circulation duct (300) to provide a path through which air discharged from the drum (200) initially passes. The mounting portion (138) may be provided in a duct shape in the first support portion (130) and may provide a space in which the filter portion (700) is accommodated and mounted.

[0084] Meanwhile, the filter unit (700) may be mounted on the mounting unit (138) to allow air to pass through while filtering lint and foreign substances contained in the air. Here, the filter unit (700) may include an internal filter (800) mounted on the mounting unit (138) to filter foreign substances from the air discharged from the drum (200).

[0085] Here, the internal filter (800) can be mounted on the mounting portion (138) to form the inner surface of the inlet (133), and is formed so as not to protrude from the inner surface of the inlet (133) toward the inside of the inlet (133). In addition, the internal filter (800) can be provided with an area or shape corresponding to the shape of the inlet of the mounting portion (138). Accordingly, the gap between the internal filter (800) and the mounting portion (138) can be minimized, thereby preventing foreign substances or parts of clothing from being inserted between the internal filter (800) and the mounting portion (138).

[0086] Meanwhile, the filter unit (700) may further include an external filter (900) mounted on a mounting unit (138) at the bottom of the internal filter (800) to filter out foreign substances. The external filter (900) may be positioned downstream of the internal filter (800) in the flow path to additionally filter out lint and foreign substances that the internal filter (800) cannot filter.

[0087] Accordingly, the filter unit (700) can more reliably remove foreign substances such as lint from the air discharged from the drum (200). When the external filter (900) is mounted on the mounting unit (138), it may not be exposed to the inlet (133).

[0088] Meanwhile, the filter unit (700) can be supported by the mounting unit (138) to prevent it from being separated from the circulation duct (300). Here, at least a portion of the internal filter (800) can be accommodated in the external filter (900).

[0089] Accordingly, the space occupied by the internal filter (800) and the external filter (900) can be reduced to the maximum extent possible to minimize the volume of the filter unit (700).

[0105] The above first receiving body (821) is provided with a first outer frame (8210) extending from the lower portion of the support body (810) to form a mesh. On the inside of the first outer frame (8210), a plurality of first radial ribs (8212) are formed that extend in a direction parallel to the rotational radius of a compression member (860) to be described later. In addition, on the inside of the first outer frame (8210), a first radial rib (8211) is formed that intersects the first radial ribs (8212) and extends in a direction parallel to the extension direction of the compression member (860).

The first auxiliary filter rib (8213) may be in close contact with one side of the auxiliary filter (850) when the auxiliary filter (850) is installed between the first receiving body (821) and the second receiving body (823).

[0108] Here, in the case of the first and second auxiliary filter ribs (8213, 8233), they are in contact with both longitudinal sides of the auxiliary filter (850) to form a close contact between the auxiliary filter (850) and the first and second receiving bodies (821, 823), thereby preventing air flowing into the internal filter (800) and lint contained in the air from leaking between the auxiliary filter (850) and the first and second receiving bodies (821, 823).

[0109] In addition, a first auxiliary filter support member (8210a) for fixing the auxiliary filter (850) may be further formed on the inside of the first outer frame (8210) to which the first auxiliary filter rib (8213) is connected. The first auxiliary filter support member (8210a) may protrude inward from the first outer frame (8210) and be inserted into a fastening groove (855) formed in the auxiliary filter (850).

[0110] The second receiving body (823) is provided with a second outer frame (8230) extending from the lower portion of the support body (810) to form a mesh. On the inner side of the second outer frame (8230), a plurality of second radius ribs (8232) are formed that extend in a direction parallel to the rotation radius of the compression member (860) to be described later. In addition, on the inner side of the second outer frame (8230), a second radial rib (8231) is formed that intersects the second radius ribs (8232) and extends in a direction parallel to the extension direction of the compression member (860).

[0111] Here, a plurality of spaces are formed by the second radius rib (8232) and the second radial rib (8231) formed on the inner side of the second outer frame (8230), and each space may be provided with a second mesh portion (8235) for filtering lint contained in the air flowing in through the support body (810).

[0112] Meanwhile, the second radius rib (8232) may be formed in a number of parallel rotational radii of the compression member (860), and the outermost rib may be provided as a second auxiliary filter rib (8233) for supporting the auxiliary filter (850). The second auxiliary filter rib (8233) may be in close contact with the other side of the auxiliary filter (850) when the auxiliary filter (850) is installed between the second receiving bodies (823) and the second receiving bodies (823).

[0113] Additionally, a second auxiliary filter support member (8230a) for fixing the auxiliary filter (850) may be further formed on the inner side of the second outer frame (8230) to which the second auxiliary filter rib (8233) is connected. The second auxiliary filter support member (8230a) may protrude inward from the second outer frame (8230) and be inserted into a fastening groove (855) formed in the auxiliary filter (850).

[0114] Meanwhile, a hinge rib (824) may be further provided on the lower portion of the first receiving body (821) and the lower portion of the second receiving body (823) to connect the first receiving body (821) and the second receiving body (823). Accordingly, the first receiving body (821) and the second receiving body (823) may be rotatably coupled with the hinge rib (824) as an axis. A plurality of such hinge ribs (824) may be provided to connect the lower portion of the first outer frame (8210) of the first receiving body (821) and the lower portion of the second outer frame (8230) of the second receiving body (823).

[0115] In addition, the hinge rib (824) described above may be provided so that the support rib (853) of the auxiliary filter (850) described later is fixedly supported. That is, the hinge rib (824) may be formed in a state in which the first receiving body (821) and the second receiving body (823) are connected in a curved shape when the first receiving body (821) and the second receiving body (823) are combined, and the support rib (853) of the auxiliary filter (850) may be fixed between the first receiving body (821) and the second receiving body (823) by being fixed on the inner side of the curved surface of the hinge rib (824) that is curved in a curved shape.

[0116] Meanwhile, not only the receiving body (820) but also the supporting body (810) may be provided so as to be detachable from each other. The supporting body (810) may be provided so that the portion where the first receiving body (821) is coupled and the portion where the second receiving body (823) is coupled are detachably coupled from each other.

[0117] The above auxiliary filter (850) is attached to the inner lower portion of the first receiving body (821) and the second receiving body (823) to filter lint contained in the air flowing into the receiving body (820) from the support body (810) and moving to the inner lower portion of the receiving body (820). This auxiliary filter (850) will be described in detail with reference to the drawings after the description of the compression part.

[0118] The above compression unit (860) can move and collect the filtered lint by compressing it to both sides of the filtering space by rotating the filtering space formed by the first receiving body (821) and the second receiving body (823) in the first mesh portion (8215) of the first receiving body (821) and the second mesh portion (8235) of the second receiving body (823).

[0119] Meanwhile, a moving groove (814) is formed on one side of the support body (810) so that the compression part (860) can be moved in the longitudinal direction of the support body (810), and the compression part (860) can be provided so as to be rotatable in both directions in the longitudinal direction of the filtering space while moving along the moving groove (814).

[0120] Here, the moving home (814) extends in the longitudinal direction of the support body (810) along the open surface (812) of the internal filter (800), and can be formed in an arc shape corresponding to the shape of the open surface (812).

[0121] Meanwhile, the compression part (860) is slidably fastened along the shape of the movable groove (814) and includes a rotating part (862) that is partially exposed to the outside of the movable groove (814) formed in the support body (810) and has a brush part (871) fastened to the lower part, and a brush part (871) that is detachably fastened to the rotating part (862) and extends downward into the filtering space to capture lint filtered in the mesh part of the first receiving body (821) and the second receiving body (823).

[0122] Here, the rotating part (862) is provided so as to reciprocate in a fan shape inside the receiving body (820) along the moving groove (814) of the support body (810). This rotating part (862) is formed with a rotating knob (864) that extends to the upper part of the open surface (812) by penetrating the moving groove (814) of the support body (810) at the upper part, a guide groove (not shown) that is movably connected to the moving groove (814) formed in the support body (810) and guides the rotating part (862) to rotate in an arc shape, and a brush connecting part (867) that is located inside the receiving body (820) and to which the brush part (871) is connected.

[0123] This rotating part (862) rotates in an arc shape along the direction of formation of the moving groove (814) as the user attaches and moves the rotating knob (864), and the brush part (871) connected to the brush connecting part (867) rotates in a fan shape so that the lint filtered and captured by the first mesh part (8215) of the first receiving body (821) and the second mesh part (8235) of the second receiving body (823) can be moved to both sides of the receiving space.

[0124] Meanwhile, the brush portion (871) is connected to and joined with the brush fastening portion (867) and can move in conjunction with the rotation of the rotating portion. In addition, the brush portion (871) can be provided with an insertion portion (872) connected to the brush fastening portion (867), a brush body (874) extending from the lower portion of the insertion portion (872) to the filtering space of the internal filter (800), and a plurality of brushes provided on the brush body (874).

[0125] Here, the insertion part (872) of the brush part (871) is detachably fastened to the brush fastening part on the inside of the internal filter, and the brush part (871) that is worn out or damaged during long-term use of the compression part (860) can be replaced.

[0126] Here, the insertion portion (872) is formed in a shape corresponding to the insertion space of the brush fastening portion (867), and the brush body (874) is formed by extending to the filtering space formed by the first receiving body (821) and the second receiving body (823) of the internal filter (800) at the bottom.

[0127] Meanwhile, the brush body (874) is formed to have one surface facing the first mesh portion (8215) of the first receiving body (821), the other surface facing the second mesh portion (8235) of the second receiving body (823), and the lower surface facing the auxiliary filter mesh portion (856) of the auxiliary filter (850).

[0128] Such a brush body (874) may be provided with a first brush (785) that contacts the first mesh portion (8215) of the first receiving body (821) on one side, a second brush (876) that contacts the second mesh portion (8235) of the second receiving body (823) on the other side, and a third brush (877) that contacts the auxiliary filter mesh portion (856) of the auxiliary filter (850) on the lower side.

[0129] Meanwhile, in the case of the first brush (785), the second brush (876), and the third brush (877) of the brush body (874) described above, they may be integrally formed by insert injection during the manufacturing of the brush body (874), or alternatively, each of the first brush (785), the second brush (876), and the third brush (877) may be separately and detachably attached to the brush body (874).

[0130] Meanwhile, the first brush (785) and the second brush (876) may be formed to extend from the brush body (874) toward the inner surfaces of the first receiving body (821) and the second receiving body (823), as illustrated in FIG. 11. The first brush (785) and the second brush (876) may move the filtered lint on the surface of the first mesh portion (8215) of the first receiving body (821) and the second mesh portion (830) of the second receiving body (823) to both sides of the internal filter (800) according to the rotation of the pressing portion (860).

[0131] Additionally, the third brush (877) of the brush body (874) can move the filtered lint on the surface of the auxiliary filter mesh portion (856) of the auxiliary filter (850) to both sides of the inner filter (800) according to the rotation of the compression portion (860).

[0132] Meanwhile, the brush portion (871) may be elastically supported toward the auxiliary filter (850) with respect to the rotating portion (862). That is, although not shown, a separate tension spring (not shown) may be further provided in the brush fastening portion (867) of the rotating portion (862) to elastically support the insertion portion (872) of the brush portion (871) toward the auxiliary filter (850).

[0133] That is, the insertion part (872) of the brush part (871) can be movably fastened to the brush fastening part (867) of the rotating part (862) in the radial direction of the rotating part (862), and a tension spring that elastically supports the insertion part (872) in a direction away from the brush fastening part (867) can be provided between the brush fastening part (867) and the insertion part (872).

[0134] Accordingly, as the rotating part (862) of the compression part (860) rotates, the brush body (874) of the brush part (871) that rotates together with the rotating part (862) presses the auxiliary filter mesh part (856) of the auxiliary filter (850), thereby allowing the lint filtered in the auxiliary filter (850) to be captured on both sides of the rotational movement direction of the compression part (860).

[0135] Hereinafter, the auxiliary filter (850) inserted and fixed between the first receiving body (821) and the second receiving body (823) of the internal filter (800) as described above will be described in detail with reference to the attached drawing.

[0136] FIG. 8 is a perspective view showing an auxiliary filter according to an embodiment of the present invention, FIG. 9 is a front view showing an auxiliary filter according to an embodiment of the present invention, and FIG. 10 is a plan view showing an auxiliary filter according to an embodiment of the present invention.

[0137] The above auxiliary filter (850) may be provided with an auxiliary filter frame (852) having a shape corresponding to the inner surface of the first receiving body (821) and the second receiving body (823) as illustrated in FIG. 8 and having an auxiliary filter mesh portion (856) provided on the inner side.

[0138] Here, the auxiliary filter mesh portion (856) provided in the auxiliary filter (850) may have a mesh having a different size from each mesh portion formed in the first receiving body (821) and the second receiving body (823).

[0139] Meanwhile, the auxiliary filter (850) may further include an auxiliary filter frame (852) positioned in a lower space formed by the first receiving body (821) and the second receiving body (823) when the first receiving body (821) and the second receiving body (823) are connected, and an auxiliary filter mesh portion (856) provided in a lower open space of the auxiliary filter frame (852).

[0140] Here, the auxiliary filter frame (852) is formed in a rectangular shape with the upper and lower parts open, and the auxiliary filter frame (852) is formed so that it can be placed between the lower parts of the first receiving body (821) and the second receiving body (823).

[0141] In addition, a plurality of reinforcing ribs (852a) are formed on the inside of the auxiliary filter frame (852) to maintain the shape of the auxiliary filter frame (852), and a plurality of support ribs (853) may be formed on the lower part of the auxiliary filter frame (852) so that the auxiliary filter (850) is supported by a hinge rib (824) connecting the first receiving body (821) and the second receiving body (823). Here, the support ribs (853) may be formed to extend from the lower part of the reinforcing ribs (852a) toward the hinge ribs (824). Therefore, the reinforcing ribs (852a), the support ribs (853), and the hinge ribs (824) may be formed in the same number.

[0142] Meanwhile, the auxiliary filter (850) and the auxiliary filter mesh portion (856) may be formed as a curved surface having a predetermined curvature to correspond to the rotation radius of the brush portion (871) to be described later. That is, in the case of the movable groove (814) to which the brush portion (871) is movably coupled, it may be formed in an arc shape centered on the inlet (133).

[0143] Accordingly, the brush portion (871) that is movably connected to the moving home (814) can rotate along the curvature of the moving home (814). That is, the brush portion (871) that rotates along the moving home (814) can rotate to have a fan-shaped rotation area within the receiving body (820).

[0144] Meanwhile, if the auxiliary filter mesh portion (856) is formed in a straight line, it is impossible to remove lint by the brush portion (871) on the outer side of the rotation radius of the brush portion (871) having a fan-shaped rotation area. Therefore, it is preferable that the auxiliary filter mesh portion (856) be formed to have a predetermined curvature (R1) corresponding to the rotation radius of the brush portion (871), as illustrated in FIG. 9.

[0145] Accordingly, when the brush portion (871) of the pressing portion (860) rotates in accordance with the movement of the rotating portion (862), the third brush (877) located at the bottom of the brush portion (871) moves along the curvature (R1) of the auxiliary filter mesh portion, thereby allowing the lint filtered in the auxiliary filter mesh portion (856) to be moved and collected to both sides of the auxiliary filter (850).

[0146] Meanwhile, the auxiliary filter frame (852) may be interposed and fixed between the first receiving body (821) and the second receiving body (823). To this end, a first auxiliary filter support (8210a) and a second auxiliary filter support (8230a) on which the auxiliary filter frame (852) is mounted may be formed on the inner side of each of the first outer frame (8210) of the first receiving body (821) and the second outer frame (8230) of the second receiving body (823).

[0147] In addition, fastening portions (854) are formed at both longitudinal ends of the auxiliary filter frame (852) to be mounted on the first auxiliary filter support portion (8210a) and the second auxiliary filter support portion (8230a), respectively. Here, the first and second auxiliary filter support portions (8210a, 8230a) and the fastening portion (854) may be formed in a structure in which they are fastened to each other, and when the first and second auxiliary filter support portions (8210a, 8230a) are formed in a protrusion shape, fastening grooves (855) may be formed in the fastening portion (854) to insert the first and second auxiliary filter support portions (8210a, 8230a), respectively.

[0148] Meanwhile, the auxiliary filter (850) is fastened in a state where it is interposed between the first receiving body (821) and the second receiving body (823) when the first receiving body (821) and the second receiving body (823) are fastened. At this time, if a gap occurs between the auxiliary filter (850) and the first receiving body (821) or the auxiliary filter (850) and the second receiving body (823), the air introduced into the internal filter (800) and the lint contained in the air may leak out through the gap between the auxiliary filter (850) and the first receiving body (821) or the auxiliary filter (850) and the second receiving body (823).

[0149] Therefore, it is necessary to prevent a gap from occurring between the auxiliary filter (850) and the first receiving body (821) or the auxiliary filter (850) and the second receiving body (823). The longitudinal sides of the auxiliary filter frame (852) may be formed convexly with a predetermined curvature toward the first receiving body (821) and the second receiving body (823).

[0150] That is, as shown in FIG. 10, the longitudinal sides of the auxiliary filter frame (852) can be formed convexly with a predetermined curvature (R2) toward the first receiving body (821) and the second receiving body (823), respectively, and the center side of the auxiliary filter (850) can be formed wider than the gap between the first receiving body (821) and the second receiving body (823) where the auxiliary filter (850) is installed.

[0151] Accordingly, in the case of the auxiliary filter (850) interposed between the first receiving body (821) and the second receiving body (823), it is interposed between the first auxiliary filter rib (8213) of the first receiving body (821) and the second auxiliary filter rib (8233) of the second receiving body (823), and a convex shape formed with a predetermined curvature on both sides of the longitudinal direction of the auxiliary filter (850) is in close contact with the first auxiliary filter rib (8213) and the second auxiliary filter rib (8233), thereby preventing air introduced into the internal filter (800) and lint contained in the air from leaking out.

[0152] Although preferred embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that various modifications and variations of the present invention can be made without departing from the spirit and scope of the invention as defined in the appended claims, or that the individual components of the embodiments included in the present invention can be combined and implemented. Accordingly, modifications to future embodiments of the present invention will not depart from the scope of the present invention.
