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 puts 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] In addition, in the case of the filter assembly of the dryer according to the prior art as described above, it is installed to be inserted into the exhaust duct through which air discharged from the drum passes. Such a filter assembly may be incorrectly installed or may come off from the installation location in the exhaust duct during operation of the dryer if it is inserted into the exhaust duct without an additional support structure.

[0016] Meanwhile, if the filter assembly is dislodged from the installation location formed in the exhaust duct, foreign substances contained in the air moving through the exhaust duct may not be filtered by the filter assembly and may flow into the air flow path, and these foreign substances may accumulate in the air flow path and the condenser or evaporator. If foreign substances accumulate in the air flow path and the condenser or evaporator in this way, the efficiency of the dryer may be seriously reduced.

[0017] Accordingly, a separate structure is required to fix and support the inserted state of the filter assembly so that the filter assembly does not come out of the installation position formed in the exhaust duct.

[0018] The present invention has been devised to solve the above problems, and its purpose is to provide a clothing treatment device capable of maintaining the installation state of a filter unit that filters lint generated during clothing treatment.

[0019] In addition, 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.

[0060] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. In this specification, identical or similar components are assigned identical or similar reference numerals even in different embodiments, and the description thereof is replaced with the first description. The singular expression used in this specification includes plural expressions unless the context clearly indicates otherwise. In addition, when describing the embodiments disclosed in this specification, if a detailed description of a related known technology is judged to obscure the gist of the embodiments disclosed in this specification, the detailed description thereof will be omitted. In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification should not be construed as being limited by the attached drawings.

[0061] Hereinafter, a garment treatment device according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0062] Fig. 1 is a perspective view showing the external appearance of a clothing treatment device according to the present invention, and Fig. 2 is a simplified diagram showing the internal structure of a clothing treatment device according to the present invention.

[0063] As shown, the clothing treatment device (1) of the present invention may include a cabinet (100), a drum (200) that is rotatably provided inside the cabinet to provide a space for storing clothing, a circulation duct (300) that forms a path for resupplying air discharged from the drum (200) to the drum (200), a heat exchange unit (400) that dehumidifies and heats air introduced into the circulation duct (300) and then resupplies it to the drum (200), and a driving unit (280) that provides rotational force to the drum.

[0064] The cabinet (100) may include a front panel (110) forming the front surface of the garment treatment device (1), an upper panel (125) forming the upper surface, a side panel (127) forming the side surface, etc. Here, the front panel (110) may be provided with an opening (111) provided to communicate with the drum (200) and a door (112) rotatably coupled to the cabinet (100) to open and close the opening (111).

[0065] Meanwhile, the door (112) may be hingedly connected to the front panel (110) of the cabinet (100) so that the opening (111) can be opened and closed. A door glass (113) may be further provided in the center of the door (112) so that the loading status and washing status of clothes loaded into the drum (200) can be checked.

[0066] Here, the door glass (113) can be formed to protrude in a convex shape in the inner direction of the drum (200) so as to allow the state inside the drum (200) to be checked and, at the same time, to move clothes moving toward the front (i.e., the opening (111)) of the drum (200) according to the rotation of the drum (200) toward the inner side of the drum (0).

[0067] In this case, the door glass (113) can prevent the clothes from being moved back to the inside of the drum (200) and caught in the gap between the door (113) and the drum (200) due to the protruding shape of the door glass when the clothes rotating inside the drum (200) are moved forward of the drum (200) by centrifugal force as the drum (200) rotates.

[0068] In addition, a pressure inclined surface (113a) for pressing the filter unit (700) to be described later may be further formed on the lower portion protruding toward the inside of the drum of the door glass (113). The pressure inclined surface (113a) may be formed as an upward inclined surface from the lower rear surface of the door glass (113) toward the inside of the drum (200), and may have a gap adjacent to the filter unit (700) but not completely in contact with the filter unit (700).

[0069] That is, when the pressure inclined surface (113a) of the door glass (113) directly contacts the filter unit (700) itself, the door (113) may not be completely closed depending on the clearance of the filter unit (700) when the filter unit (700) is not fully inserted. Therefore, the filter unit (700) may further be provided with a pressure portion (880, 880a, 880b, 880c) that contacts the pressure inclined surface (113a) of the door glass (113) so that the filter unit (700) can be seated on the mounting portion (138) described later by a predetermined elastic force.

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).

[0083] 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.

[0084] 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).

[0085] 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.

[0086] 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.

[0087] 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).

[0088] 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).

[0100] 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).

[0101] 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.

[0102] 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).

[0103] 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).

[0104] 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.

[0105] 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).

[0106] 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).

[0107] 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). In addition, the user can be guided to pull out the internal filter (800) and the external filter (900) as a single unit or mount them simultaneously on the mounting unit (138).

[0108] Meanwhile, the external filter (900) may include a mounting body (910) mounted on the mounting portion (138), and an insertion body (920) that extends downward from the mounting body (910) and is at least partially inserted into the mounting portion (138) while simultaneously accommodating the receiving body (820) of the internal filter (800).

[0109] Here, the mounting body (910) may include an open surface at the top through which air and foreign substances may enter, and may include a mounting base (911) that may be mounted and supported on the top of the mounting portion (138). In addition, the insertion body (920) may be provided to extend downward from the inner surface of the mounting base (911) and be inserted into the mounting portion (138).

[0110] Meanwhile, the insertion body (920) may be provided in a case shape that provides a space for foreign substances to accumulate inside. In addition, the insertion body (920) may be provided with a through hole for most of its area, and a mesh (921) that is coupled to the through hole and can filter foreign substances may be provided. The mesh (921) may be provided with a mesh member or the like so that air can pass through but foreign substances can be filtered.

[0111] Meanwhile, the insertion body (920) may include a first insertion body (922) that extends from the lower portion of the mounting body (910) to filter foreign substances, and a second insertion body (923) that is rotatably provided at the lower portion of the first insertion body (922) to form an insertion space in which an internal filter (800) is inserted together with the first insertion body (922).

[0112] Meanwhile, the external filter (900) may further include a rigid portion (930) that reinforces the rigidity of the first insertion body (922) and the second insertion body (923) and maintains the shape when the first insertion body (922) and the second insertion body (923) are inserted into the mounting portion (138). The rigid portion (930) is formed in a rib shape extending in the width direction of the mounting body (910) and may further include a hinge function so that the first insertion body (922) and the second insertion body (923) can rotate.

[0113] Hereinafter, an internal filter (800) according to an embodiment of the present invention will be described in detail with reference to the attached drawings 6 and 7.

[0114] FIG. 6 is an exploded perspective view showing an internal filter according to an embodiment of the present invention, and FIG. 7 is a cross-sectional view showing an internal filter according to an embodiment of the present invention.

[0116] The above support body (810) may be provided to correspond to the shape and area of ​​the mounting hole (138a), and may be provided to form a part of the inlet (133). In addition, the support body (810) may include an open surface (812) through which air and foreign substances may enter the upper surface, and a plurality of blocking ribs (811) provided to shield at least a part of the open surface (812).

[0117] Meanwhile, a blocking rib (811) may be provided to block the inflow of large materials such as clothing as well as small foreign substances such as air or lint into the open surface (812). The blocking rib (811) may be provided like a net on the open surface (812).

[0118] Meanwhile, the upper surface of the support body (810) may include a coupling portion (815a) that couples the support body (810) to the mounting portion (138) or guides the installation and withdrawal direction of the internal filter (800). The area of ​​the support body (810) may be larger than the area of ​​the receiving body (820).

[0119] Additionally, the support body (810) may include a mounting surface (813) extending further outward from the upper surface of the receiving body (820) at the lower portion. The mounting surface (813) may be supported on the upper portion of the mounting hole (138a) to prevent the internal filter (800) from falling into the mounting hole (138a).

[0120] The above-mentioned receiving body (820) is provided in a box shape with an internal space, extends from the lower portion of the support body (810), and can provide a space in which foreign substances accumulate inside.

[0121] Meanwhile, the receiving body (820) may include a first receiving body (821) that extends from the lower portion of the support body (810) to filter foreign substances, and a second receiving body (823) that is rotatably or detachably provided at the lower portion of the first receiving body (821) to form a space for accumulating foreign substances together with the first receiving body (821).

[0122] Here, the first receiving body (821) and the second receiving body (823) can be rotated or detached from each other, so that the receiving body (820) can be opened internally. Accordingly, the user can remove foreign substances filtered by the first receiving body (821) and the second receiving body (823) and accumulated in the receiving body (820).

[0123] 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).

[0124] Here, a plurality of spaces are formed by the first radius rib (8212) and the first radial rib (8211) formed on the inner side of the first outer frame (8210), and each space may be provided with a first mesh portion (8215) for filtering lint contained in air flowing in through the support body (810).

[0125] Meanwhile, the first radius rib (8212) may be formed in a plurality of parallel rotational radii of the compression member (860), and the outermost rib (i.e., the lowest rib) may be provided with a first auxiliary filter rib (8213) for supporting the auxiliary filter (850). 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).

[0126] 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).

[0127] 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).

[0128] 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).

[0129] 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).

[0130] 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).

[0131] 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).

[0132] 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).

[0133] 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.

[0134] 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.

[0135] 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).

[0136] This 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) and having an auxiliary filter mesh portion (856) provided on the inner side.

[0137] 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).

[0138] 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).

[0139] In addition, a plurality of reinforcing ribs may be 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 toward the hinge ribs (824).

[0140] 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).

[0141] 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).

[0142] 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).

[0143] 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).

[0144] 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.

[0145] 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).

[0146] 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).

[0147] 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).

[0148] 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).

[0149] 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.

[0150] 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) attached to the brush fastening 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.

[0151] 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).

[0152] 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.

[0153] 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.

[0154] 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).

[0155] 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.

[0156] 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).

[0157] 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).

[0158] 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).

[0159] 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).

[0160] 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).

[0161] 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).

[0162] Hereinafter, a structure in which the filter part (700) as described above is inserted into the mounting part (138) and is supported by pressure on the door glass (113) of the door will be described in detail with reference to the attached drawing.

[0163] Fig. 8 is a perspective view showing a door glass and a filter unit according to an embodiment of the present invention.

[0164] As illustrated in Fig. 8, the filter unit (700) is positioned at the bottom of the door glass (113) of the door (112) when the door (112) is closed in the inserted state of the mounting unit (138) into which the filter unit (700) is inserted. Here, a pressing unit (880, 880a, 880b, 880c) that comes into contact with the lower portion of the pressing slope (113a) of the door glass (113) may be provided at the upper portion of the inner filter (800) of the filter unit (700).

[0165] These pressurizing portions (880, 880a, 880b, 880c) can be formed anywhere on the upper surface of the filter portion (700) adjacent to the pressurizing inclined surface (113a) formed on the door glass (113) of the door (112). That is, in the case of the support body (810) of the internal filter (800) of the filter portion (700), it can be formed in an arc shape corresponding to the shape of the inlet, and in the case of the pressurizing inclined surface (113a) of the door glass (113), it can be formed to protrude in a cone shape toward the inside of the drum (200) corresponding to the shape of the inlet.

[0166] Accordingly, the outer surface of the pressure inclined surface (113a) of the door glass (113) is located on the upper portion of the support body of the internal filter, and regardless of where the pressure portion (880, 880a, 880b, 880c) is located between the arc shapes of the support body (810) of the internal filter (800), the pressure portion (880, 880a, 880b, 880c) can be pressed by the pressure inclined surface (113a), and as the pressure portion (880, 880a, 880b, 880c) is pressed, the filter portion (700) where the pressure portion (880, 880a, 880b, 880c) is located can be pressed and fixed to the mounting portion (138).

[0167] In addition, in the case of the filter unit (700), the internal filter (800) can be installed in a structure in which it is inserted into the external filter (900) and then inserted into the mounting unit (138). Accordingly, when a pressing unit (880, 880a, 880b, 880c) is formed in the internal filter (800), the external filter (900) into which the internal filter (800) is inserted can also be tightly inserted into the mounting unit (138) by the pressing force of the pressing unit (880, 880a, 880b, 880c).

[0168] Hereinafter, the main components of the present invention, the pressurizing parts (880, 880a, 880b, 880c), will be described in detail with reference to the attached drawings for examples. In the following description, the pressurizing parts (880, 880a, 880b, 880c) are described as being located in the internal filter (800), but the filter part (700) may not be composed of the internal filter (800) and the external filter (900), but may be composed of a single filter. However, if the filter part (700) composed of a single filter is supported by being pressed by the door glass (113), it should be considered to be included in the scope of the present invention.

[0169] [First embodiment]

[0170] Hereinafter, the pressurizing structure according to the first embodiment of the present invention will be described in detail with reference to FIG. 9.

[0171] Figure 9 is a cross-sectional view showing a pressurizing structure according to the first embodiment of the present invention.

[0172] As illustrated in FIG. 9, the first embodiment of the present invention exemplifies that a pressing portion (880) is provided in the rotating portion (862) of the pressing portion (860) provided in the internal filter (800) of the above-described embodiment. The pressing portion (880) according to the first embodiment is provided in the rotating knob (864) provided in the rotating portion of the pressing portion (860), so that when the door (112) is closed, the pressing portion (880) provided in the rotating portion (862) presses the pressing slope (113a) of the door glass (113), thereby supporting the inserted state of the filter portion (700).

[0173] Here, the rotation knob (864) is formed to be movable along the movable groove (814) of the support body (810) as in the embodiment described above, and an elevating groove (8641) into which a pressing part (880) can be inserted to be movable can be formed at the upper portion, and a support surface (8642) for supporting the pressing part (880) is formed at the lower portion of the elevating groove (8641).

[0174] Meanwhile, the pressurizing unit (880) may be provided with a pressurizing unit body (881) that is movably inserted into the lifting groove (8641) of the rotary knob (864), and an elastic rib (883) that extends obliquely from the lower portion of the pressurizing unit body (881) to the support surface (8642).

[0175] Here, the elastic rib (883) of the pressurizing body (881) exerts elastic force in the direction in which the pressurizing body (881) rises with respect to the support surface (8642), and elastically supports the pressurizing body (881) so that it can always protrude with respect to the lifting groove (8641).

[0176] In addition, when the pressurized body (881) is pressed by the pressurized inclined surface (113a) of the door glass (113), the support surface (8642) is pressed with a predetermined elastic force, so that the internal filter (800) formed by the support surface (8642) can be elastically supported so as to be inserted into the mounting portion (138) with a predetermined elastic force.

[0177] In addition, the upper surface of the pressurizing body (881) may be formed with a pressurizing surface (882) that is inclined corresponding to the pressurizing slope (113a) of the door glass (113). In addition, the elastic rib (883) may be extended from one side of the lower portion of the body of the pressurizing body (880) and positioned so that the end is in contact with the support surface (8642).

[0178] Meanwhile, a catch projection (8811) may be further formed on the outer surface of the pressurizing body (881) to be inserted into a catch groove (8641a) formed in the lifting groove (8641) to prevent the pressurizing body (881) from being separated from the lifting groove. Here, the catch groove (8641a) may be formed along the lifting groove (8641) to a predetermined length corresponding to the distance by which the pressurizing body (880) is lifted.

[0179] According to the pressurizing unit (880) according to the first embodiment as described above, when the filter unit (700) is inserted into the mounting unit (138), the pressurizing slope (113a) of the door glass (113) can pressurize the pressurizing unit (880) as the door (112) rotates in the direction of closing the opening.

[0180] Here, the pressure inclined surface (113a) of the door glass (113) presses the pressure surface (882) of the pressure body (881), and the pressure body (881) on which the pressure surface (882) is pressed descends along the lifting groove (8641).

[0181] Meanwhile, the pressurized body (881) is supporting the support surface (8642) by the elastic rib (883), and as the pressurized body (881) descends, it overcomes the elastic force of the elastic rib (883) and descends to pressurize the support surface (8642).

[0182] Accordingly, the pressure applied to the pressurizing portion (880) by the pressurizing slope (113a) of the door glass (113) is applied in the direction in which the internal filter (800) is inserted into the mounting portion (138), and the filter portion (700) including the external filter (900) into which the internal filter (800) is inserted can be inserted into the mounting portion (138) at a predetermined pressure.

[0183] In addition, as the door (112) is closed, the door glass (113) of the door (112) presses the pressurizing portion (880) of the filter portion (700), so that the filter portion (700) can be pressed against the mounting portion (138) and maintained in the inserted state.

[0184] [Second Embodiment]

[0185] Hereinafter, a pressurizing structure according to a second embodiment of the present invention will be described in detail with reference to FIGS. 10 and 11.

[0186] Fig. 10 is a perspective view showing a pressurizing structure according to a second embodiment of the present invention, and Fig. 11 is a cross-sectional view showing a pressurizing structure according to a second embodiment of the present invention.

[0187] The pressurizing portion (880a) according to the second embodiment of the present invention is formed on the support body (810) of the internal filter (800) and pressurizes the support body (810) itself, thereby maintaining the state in which the filter portion (700) is inserted into the mounting portion (138).

[0188] As shown in FIGS. 10 and 11, the pressurizing portion (880a) according to the second embodiment of the present invention can be formed by protruding integrally with the support body (810) on one side of the open surface (812) formed in the support body (810) of the internal filter (800).

[0189] That is, on one side of the support body (810), a pressure body (881a) that curves and protrudes toward the pressure slope (113a) of the door glass (113) and an insertion protrusion (884a) that is inserted into the space between the blocking rib (811) of the support body (810) at the end of the pressure body (881a) can be formed.

[0190] Here, the front end of the pressure body (881a) extending from the support body (810) can be formed with an elastic rib (883a) having a predetermined elasticity, and the upper surface of the pressure body (881a) (i.e., one surface facing the pressure inclined surface (113a)) can be formed with a pressure surface (882a) that is in contact with the pressure inclined surface (113a) of the door glass (113).

[0191] Meanwhile, the pressurized body (881a) can be bent toward the blocking rib (811) of the support body (810) by extending and protruding from the outer surface of the support body (810) and can be inserted into the open surface (812) formed between the blocking ribs (811).

[0192] The insertion projection (884a) formed at the end of the pressurizing body (881a) can be spaced apart from the blocking rib (811) by a predetermined gap (885a) when inserted into the open surface (812) of the support body (810). The gap between the insertion projection (884a) and the blocking rib (811) can form a space in which the pressurizing body (881a) can be elastically deformed when the pressurizing surface (882a) of the pressurizing body (881a) is pressed by the pressurizing inclined surface (113a) of the door glass (113).

[0193] According to the pressurizing part (880a) according to the second embodiment as described above, when the filter part (700) is inserted into the mounting part (138), the pressurizing slope (113a) of the door glass (113) can pressurize the pressurizing part (880a) as the door (112) rotates in the direction of closing the opening.

[0194] Here, the pressure inclined surface (113a) of the door glass (113) presses the pressure surface (882a) of the pressure body (881a), and the pressure body (881a) to which the pressure surface (882a) is pressed is inserted while the elastic rib (883a) of the pressure body (881a) is elastically deformed and the insertion projection (884a) is bent into the open surface (812) formed between the blocking ribs (811).

[0195] Meanwhile, the pressurizing body (881a) is elastically supported by the elastic force of the elastic rib (883a). Therefore, the pressure applied to the pressurizing portion (880a) by the pressurizing slope (113a) of the door glass (113) is applied in the direction in which the internal filter (800) is inserted into the mounting portion (138), and the filter portion (700) including the external filter (900) into which the internal filter (800) is inserted can be inserted into the mounting portion (138) with a predetermined pressure.

[0196] Accordingly, when the door (112) is closed, the door glass (113) of the door (112) presses the pressurizing portion (880a) of the filter portion (700), so that the filter portion (700) can be pressed against the mounting portion (138) and maintained in the inserted state.

[0197] [Example 3]

[0198] Hereinafter, a pressurizing structure according to a third embodiment of the present invention will be described in detail with reference to FIGS. 12 and 13.

[0199] Fig. 12 is an exploded perspective view showing a pressurizing structure according to a third embodiment of the present invention, and Fig. 13 is a cross-sectional view showing a pressurizing structure according to a third embodiment of the present invention.

[0200] The pressurizing unit (880b) according to the third embodiment of the present invention is provided on the support body (810) of the internal filter (800) and pressurizes the support body (810) itself, thereby maintaining the state in which the filter unit (700) is inserted into the mounting unit (138).

[0201] As shown in FIGS. 12 and 13, a pressurizing portion (880b) according to the third embodiment of the present invention may be provided on one side of an open surface (812) formed in a support body (810) of an internal filter (800) so as to be able to be lifted relative to the support body (810).

[0202] That is, a lifting groove (816) into which a pressing part (880b) is inserted is formed on one side of the support body (810), and the pressing part (880b) can be supported by a predetermined elastic force in the lifting groove (816) so as to be able to be lifted.

[0203] Meanwhile, a lifting groove (816) into which a pressing portion (880b) can be inserted in a lifting manner can be formed on one side or the central portion of the support body (810), and a support surface (816a) for supporting the pressing portion (880b) is formed on the lower portion of the lifting groove (816).

[0204] Meanwhile, the pressurizing part (880b) may be provided with a pressurizing part body (881b) that is movably inserted into the lifting groove (816) of the support body (810), and an elastic rib (883b) that extends obliquely from the lower portion of the pressurizing part body (881b) with respect to the support surface (816a).

[0205] Here, the elastic rib (883b) of the pressurizing body (881b) exerts elastic force in the direction in which the pressurizing body (881b) rises with respect to the support surface (816a), and elastically supports the pressurizing body (881b) so that it can always protrude with respect to the lifting groove (816).

[0206] In addition, when the pressurized body (881b) is pressed by the pressurized inclined surface (113a) of the door glass (113), the support surface (816a) is pressed with a predetermined elastic force, so that the internal filter (800) formed by the support surface (816a) can be elastically supported so as to be inserted into the mounting portion (138) with a predetermined elastic force.

[0207] In addition, the upper surface of the pressurizing body (881b) may be formed with a pressurizing surface (882b) that is inclined corresponding to the pressurizing slope (113a) of the door glass (113). In addition, the elastic rib (883b) may be extended from one side of the lower portion of the body of the pressurizing body (880b) and positioned so that its end contacts the support surface (816a).

[0208] Meanwhile, a catch rib (884b) may be further formed on the outer surface of the pressurizing body (881b) to be inserted into a catch groove (not shown) formed in the lifting groove (816) to prevent the pressurizing body (881b) from being separated from the lifting groove (816). Here, the catch groove may be formed along the lifting groove (816) to a predetermined length corresponding to the distance by which the pressurizing body (880b) is raised and lowered.

[0209] According to the pressurizing part (880b) according to the third embodiment as described above, when the filter part (700) is inserted into the mounting part (138), the pressurizing slope (113b) of the door glass (113) can pressurize the pressurizing part (880b) as the door (112) rotates in the direction of closing the opening.

[0210] Here, the pressure inclined surface (113a) of the door glass (113) presses the pressure surface (882b) of the pressure body (881b), and the pressure body (881b) to which the pressure surface (882b) is pressed descends along the lifting groove (816).

[0211] Meanwhile, the pressurizing body (881b) is supporting the support surface (816a) by the elastic rib (883b), and as the pressurizing body (881b) is lowered, it overcomes the elastic force of the elastic rib (883b) and is lowered to pressurize the support surface (816b).

[0212] Accordingly, the pressure applied to the pressurizing portion (880b) by the pressurizing slope (113a) of the door glass (113) is applied in the direction in which the internal filter (800) is inserted into the mounting portion (138), and the filter portion (700) including the external filter (900) into which the internal filter (800) is inserted can be inserted into the mounting portion (138) at a predetermined pressure.

[0213] In addition, as the door (112) is closed, the door glass (113) of the door (112) presses the pressurizing portion (880b) of the filter portion (700), so that the filter portion (700) can be pressed against the mounting portion (138) and maintained in the inserted state.

[0214] Hereinafter, a pressurizing structure according to a fourth embodiment of the present invention will be described in detail with reference to FIGS. 14 and 15.

[0215] Fig. 14 is an exploded perspective view showing a pressurizing structure according to a fourth embodiment of the present invention, and Fig. 15 is a cross-sectional view showing a pressurizing structure according to a fourth embodiment of the present invention.

[0216] The pressurizing part (880c) according to the fourth embodiment of the present invention is coupled to the support body (810) of the internal filter (800) and pressurizes the support body (810) itself, thereby maintaining the state in which the filter part (700) is inserted into the mounting part (138).

[0217] As shown in FIGS. 14 and 15, the pressurizing portion (880c) according to the fourth embodiment of the present invention can be provided by being fastened between the blocking ribs (811) of the open surface (812) formed in the support body (810) of the internal filter (800).

[0218] That is, the support body (810) is formed with an open surface (812) through which air flows in and a blocking rib (811) for filtering out the inflow of foreign substances of relatively large size other than air into the open surface (812), and the pressurizing portion (880c) may be provided to be fastened to the space formed by the blocking ribs (811). Here, the blocking rib (811) may be formed in a form in which a plurality of blocking ribs (811) intersect, and the pressurizing portion (880c) may be inserted into and fixed in the space between the intersecting blocking ribs (811).

[0219] Meanwhile, the pressurizing part (880c) is provided with a pressurizing part body (881c) having a length relatively larger than the space between the blocking ribs (811), and an elastic rib (883c) that extends upwardly in a direction parallel to the pressurizing part body (881c) from one end of the pressurizing part body (881c) to the other end of the pressurizing part body (881c).

[0220] Here, on both sides of the longitudinal direction of the pressurizing body (881c), a catch rib (884c) is formed that extends downward in the space formed by the blocking rib (811). A catch protrusion (not shown) that is mounted on the lower or inner side of the blocking rib (811) may be further formed at the end of the catch rib (884c). Accordingly, the pressurizing body (881c) can be fixed to the upper part of the support body (810) by the catch rib (884c) being mounted on the lower part of the blocking rib (811) while being seated on the upper part of the blocking rib (811).

[0221] In addition, the elastic rib (883c) may be extended from one end of the pressurizing body (881c) to the other end in parallel with the pressurizing body (881c), so that a pressurizing surface (882c) having an inclined surface parallel to the pressurizing inclined surface (113a) of the door glass (113) may be formed on the upper surface.

[0222] Meanwhile, the end of the elastic rib (883c) is formed with an insertion protrusion (887c) that is bent downward into the space between the blocking ribs (811), and the insertion protrusion (887c) can be formed to be spaced apart from the pressure body (881c) by a predetermined distance (885c) and at the same time spaced apart from the blocking rib (811) by a predetermined distance (886c). The intervals (885c, 886c) of the insertion protrusions (887c) form a space that can be elastically deformed when the elastic rib (883c) is elastically deformed.

[0223] According to the pressurizing part (880c) according to the fourth embodiment as described above, when the filter part (700) is inserted into the mounting part (138), the pressurizing slope (113c) of the door glass (113) can pressurize the pressurizing part (880c) as the door (112) rotates in the direction of closing the opening.

[0224] Here, the pressure inclined surface (113c) of the door glass (113) presses the pressure surface (882c) of the elastic rib (883c), and the elastic rib (883c) to which the pressure surface (882c) is pressed is elastically deformed in the direction of pressing the pressure body (881c). Here, the end of the elastic rib (883c) that is elastically deformed is bent and inserted into the space formed by the blocking ribs (811), and the elastic force of the elastic rib (883c) can be transmitted to the pressure body (881c).

[0225] Meanwhile, the pressurized body (881c) is fixed to the support body (810) by the catch rib (884c) while being secured to the upper portion of the blocking rib (811), and the support body (810) can be pressurized by the elastic force transmitted from the elastic rib (883c) to the pressurized body.

[0226] Accordingly, the pressure applied to the pressurizing portion (880c) by the pressurizing slope (113c) of the door glass (113) is applied in the direction in which the internal filter (800) is inserted into the mounting portion (138), and the filter portion (700) including the external filter (900) into which the internal filter (800) is inserted can be inserted into the mounting portion (138) at a predetermined pressure.

[0227] In addition, as the door (112) is closed, the door glass (113) of the door (112) presses the pressurizing portion (880c) of the filter portion (700), so that the filter portion (700) can be pressed against the mounting portion (138) and maintained in the inserted state.

[0228] 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.
