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, title: Dryer, hereinafter referred to as "prior art") discloses a dryer that includes a filter cleaning unit (140) 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-mentioned 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.

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.

[0106] 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).

[0107] 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).

[0108] 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).

[0109] 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).

[0110] 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).

[0111] 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).

[0112] 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.

[0113] 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).

[0114] Below, the mounting status of the filter unit will be described in detail with reference to the attached drawings 3 and 4.

[0115] Fig. 3 is a perspective view showing the mounting state of the filter unit according to the present invention, and Fig. 4 is a perspective view showing the filter unit according to the present invention.

[0116] The filter unit (700) as shown 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).

[0117] 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.

[0118] 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).

[0119] 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).

[0120] 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.

[0121] 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).

[0122] 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).

[0123] 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).

[0124] 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).

[0125] 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).

[0126] 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.

[0127] 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).

[0128] 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.

[0129] Hereinafter, an internal filter (800) according to an embodiment of the present invention will be described in detail with reference to the attached drawings 5 ​​to 7.

[0130] FIG. 5 is an exploded perspective view showing an internal filter according to an embodiment of the present invention, FIG. 6 is an exploded perspective view showing the fastening of a brush part according to an embodiment of the present invention, and FIG. 7 is an operation diagram showing the operation of an internal filter according to an embodiment of the present invention.

[0131] As illustrated, an internal filter (800) according to an embodiment of the present invention may include a support body (810) that is supported by being mounted on a mounting portion (138) and a receiving body (820) that extends downward from the support body (810) and is at least partially received in the external filter (900). The 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).

[0132] 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 portion of the open surface (812). The blocking ribs (811) may be provided to block the inflow of large materials such as clothing in addition to small foreign substances such as air or lint into the open surface (812). The blocking ribs (811) may be provided in the form of a mesh on the open surface (812).

[0133] Meanwhile, the upper surface of the support body (810) may include a coupling portion (815) 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 provided to be larger than the area of ​​the receiving body (820).

[0134] 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).

[0135] Meanwhile, the receiving body (820) is provided in a box shape, extends from the lower portion of the support body (810), and can provide a space for foreign substances to accumulate inside. The receiving body (820) can have a large area formed by through holes, and a mesh portion (830) that can filter foreign substances on the surface by being connected to the through holes can be installed.

[0136] Here, the mesh portion (830) may be provided in the form of a mesh that forms a through hole penetrating the receiving body (820). The mesh portion (830) may be provided to occupy most of the surface area of ​​the receiving body (820), and due to the mesh portion (830), the receiving body (820) may appear to have the shape of a frame that supports the mesh portion (830).

[0137] 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 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).

[0138] That is, the first receiving body (821) and the second receiving body (823) are provided to be separated from each other, so that the receiving body (820) can have an open interior. 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).

[0139] Here, at least one reinforcing rib (8211, 8231) extending vertically may be formed in each of the first receiving body (821) and the second receiving body (823) to reinforce the strength of the first receiving body (821) and the second receiving body (823). Accordingly, the mesh portion (830) may be positioned in a space formed by the reinforcing rib (8211, 8231) extending vertically from the inside of the first receiving body (821) and the second receiving body (823).

[0140] Meanwhile, a plurality of lint protrusions (822) are formed on each reinforcing rib (8211, 8231) of the first receiving body (821) and the second receiving body (823), through which the filtered lint is caught on the mesh portion of the first receiving body (821) and the second receiving body (823) by the brush portion (871) of the pressing portion (860) to be described later.

[0141] Here, the lint protrusions (822) may be formed to be spaced apart at regular intervals in the longitudinal direction of each reinforcing rib (8211, 8231) as illustrated in FIG. 8. In addition, the lint protrusions (822) may be formed with an inclined surface (8221) that is upwardly directed outward based on the center of the inner filter (800), and a relatively vertical engaging surface (8222) may be formed on the surface facing the outer side of the inner filter (800) with respect to the reinforcing ribs (8211, 8231).

[0142] Meanwhile, the lint protrusions (822) formed on the reinforcing ribs (8211, 8231) cause the lint moved by the first brush (875) and the second brush (876) of the brush portion (871) to move along the inclined surface (8221) to the outside of the internal filter when the brush portion (871) described later moves toward the outside of the internal filter (800), and when the brush portion (871) moves toward the center of the internal filter (800), the lint can be caught on the catch surface (8222) of the lint protrusions (822) so that the lint can be captured on both sides of the internal filter.

[0143] Here, the lint protrusions (822) are formed at regular intervals along the reinforcing ribs (8211, 8231), and the first brush (875) and the second brush (876) of the brush portion (871) can be arranged to correspond to the intervals formed by the lint protrusions (822). The first brush (875) and the second brush (876) of the brush portion (871) will be described in detail when describing the brush portion (871).

[0144] 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.

[0145] The internal filter (800) may further include a connecting portion (840) connecting the first receiving body (821) and the second receiving body (823). The connecting portion (840) may be provided in the form of a rib extending in the width direction from the lower portions of the first receiving body (821) and the second receiving body (823). The connecting portion (840) may also function as a hinge by which the first receiving body (821) and the second receiving body (823) rotate.

[0146] Meanwhile, the filtering space formed by the first receiving body (821) and the second receiving body (823) may further be provided with a pressing unit (860) for pressing and moving the lint filtered in the filtering space to both sides of the filtering space while moving the filtering space.

[0147] 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 able to move to both sides in the longitudinal direction of the filtering space while moving along the moving groove (814).

[0148] 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 may be formed in an arc shape corresponding to the shape of the open surface (812). That is, in the case of the filter unit (700), it is mounted on the mounting unit (138) formed on the inlet (133) of the first support unit (130), and it is preferable that the open surface (812) of the internal filter (800) extends in accordance with the shape of the inlet (133) and is formed in an arc shape.

[0149] Meanwhile, the compression unit (860) includes a moving shaft (861) arranged in the length direction of the support body on one side of the inside of the support body, a moving unit (862) that is slidably connected to the moving shaft (861) and partially exposed through a moving groove formed in the support body, and a brush unit (871) that is detachably connected to the moving unit (862) and extends downward into the filtering space to scrape off lint collected in the mesh portion of the first receiving body (821) and the second receiving body (823).

[0150] The above moving axis (861) is fixed parallel to the length direction of the support body (810) on the inside of the open surface (812) formed in the support body (810).

[0151] The above-described moving part (862) is provided to move along a moving axis (861) within the inner surface of the support body (810). The moving part (862) includes a moving guide (864) that is fastened to the moving axis (861) and moves in a parallel direction along the moving axis (861), a moving knob (863) that is fastened to the upper side of the moving guide (864) and extends to the upper side of the open surface (812) by penetrating the moving groove (814) of the support body (810), a lifting guide (868) that is fastened to the moving guide (864) from the lower side of the moving guide (864) so ​​as to be able to move up and down, and a fixed guide (869) that is fastened to the moving guide (864) and prevents the lifting guide (868) from coming off.

[0152] Here, the moving guide (864) is formed with a through hole (8641) through which the moving axis (861) passes, and is provided so as to be able to slide in the extension direction of the moving axis (861) along the moving axis (861) inserted into the through hole (8641).

[0153] Additionally, the moving guide (864) may further be provided with a horizontal guide (865) to prevent the moving guide (864) from flowing in an axis other than the extension direction of the moving axis (861) when moving along the moving axis (861).

[0154] The horizontal guide (865) is attached to the moving guide (864) in a direction parallel to the extension direction of the moving axis (861) in the form of a bar of a predetermined length, and the lower surface of the horizontal guide (865) can be attached to the moving guide (864) in a state in which it is in contact with the upper surface of the moving axis (861).

[0155] Accordingly, when the moving guide (864) slides along the moving axis, the lower surface of the horizontal guide (865) attached to the moving guide (864) moves in a state in which it comes into contact with the upper surface of the moving axis, so that the moving guide (864) can be stably moved along the extension direction of the moving axis.

[0156] In addition, the moving guide (864) and the horizontal guide (865) may be coupled to each other by a separate auxiliary shaft (8651) so that the horizontal guide (865) can move in the moving direction of the moving guide (864). At this time, an auxiliary spring (8652) that exerts a tensile force between the moving guide (864) and the horizontal guide (865) may be further provided between the moving guide (864) and the horizontal guide (865).

[0157] Accordingly, the moving guide (864) and the horizontal guide (865) are maintained in a spaced state with a predetermined elastic force by an auxiliary spring (8652), and as the moving guide (864) moves to one side of the internal filter, the auxiliary spring (8652) provided in the horizontal guide (865) supports the moving guide (864) with a predetermined elastic force.

[0158] Here, when the moving guide (864) is moved further to one side of the internal filter with a force greater than the elastic force of the auxiliary spring (8652), the moving guide (864) can be moved further to one side of the internal filter while overcoming the elastic force of the auxiliary spring (8652).

[0159] The above-mentioned lifting guide (868) may be provided at the lower portion of the moving guide (864) so ​​as to be able to slide up and down relative to the moving guide (864). Accordingly, an lifting space in which the lifting guide (868) can be lifted up and down may be formed at the lower portion of the moving guide (864).

[0160] Here, a fastening part (872) of a brush part (871) to be described later can be fastened to the lifting guide (868). A fastening space in which the fastening part (872) can be mounted is formed in the lifting guide (868), and a catch groove (8682) is formed in the fastening space. The catch grooves (8682) are formed to face each other in opposite directions on both sides of the lifting guide (868), and a catch projection (873) of the fastening part to be described later is respectively mounted.

[0161] Meanwhile, an elevating shaft (866) may be further provided between the elevating guide (868) and the moving guide (864) to guide the elevating of the elevating guide (868). The elevating shaft (866) is fixed to the upper lower surface of the elevating space formed in the moving guide (864), and the elevating guide (868) is provided so that the elevating shaft (866) passes through it.

[0162] Here, the lifting shaft (866) may further be provided with a tension spring (867) that exerts tension between the moving guide (864) and the lifting guide (868). The tension spring (867) may provide elasticity to the lifting guide (868) in a downward direction with respect to the moving guide (864).

[0163] Since the lifting guide (868) is elastically supported in the downward direction with respect to the moving guide (864), the brush portion (871) attached to the lifting guide (868) can also be elastically supported in the downward direction of the moving guide (864) like the lifting guide (868). Accordingly, the brush portion (871) is always elastically supported in the downward direction of the internal filter (800) and can be elastically supported up to the lower part of the filtering space of the internal filter (800).

[0164] Meanwhile, the moving guide (864) may further be provided with a fixed guide (869) to prevent the brush portion (871) attached to the lifting guide (868) from being detached. The fixed guide (869) is hinge-connected to the upper end of the moving guide (864) and rotates in a direction in which the lower end presses the attachment portion (872) of the brush portion (871), thereby preventing detachment of the brush portion (871).

[0165] The above brush part (871) may be provided with a fastening part (872) that is inserted into and fastened to the lifting guide (868), a brush body (874) that extends from the lower portion of the fastening part (872) to the filtering space of the internal filter (800), and a plurality of brushes (875, 876, 877) provided on the brush body (874).

[0166] Here, the fastening portion (872) is formed in a shape corresponding to the fastening space (8681) of the lifting guide (868), and may be provided with a pair of catches (873) inserted into the catch grooves (8682) of the lifting guide (868) on both sides. Here, the catches (873) may be formed in the form of elastic pieces to have a predetermined elasticity toward the outside of the fastening portion (872), and as the fastening portion (872) is inserted into the lifting guide (868), the catches (873) may be inserted into the catch grooves (8682) to prevent detachment.

[0167] Meanwhile, the catch (873) of the fastening portion (872) may be detached from the catch groove (8682) when an external force is applied, and the fastening portion (872) may be separated from the lifting guide (868). That is, the brushes (875, 876, 877) provided in the brush portion (871) may be worn / aged when used for a long time, and the brushes (875, 876, 877) may be provided to be replaced after a certain period of use.

[0168] Meanwhile, the brush body (874) is formed to extend from the lower portion of the fastening portion (872) to the filtering space formed by the first receiving body (821) and the second receiving body (823) of the internal filter (800). The brush body (874) is formed to have one side facing the mesh portion of the first receiving body (821) and the other side facing the mesh portion of the second receiving body (823), and a first brush (875) and a second brush (876) that contact the mesh portion of the first receiving body (821) and the mesh portion of the second receiving body (823) may be provided on the one side and the other side, respectively.

[0169] Meanwhile, in the case of the first brush (875) and the second brush (876) 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, they may be detachably attached separately to the brush body (874).

[0170] Meanwhile, the brush part (871) of the internal filter (800) according to one embodiment of the present invention described above is as shown in FIG. 8.

[0171] FIG. 8 is an enlarged perspective view showing a portion of a brush frame and a receiving body according to one embodiment of the present invention.

[0172] As illustrated in FIG. 8, the first brush (875) 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). The first brush (875) and the second brush (876) may move the filtered lint on the surface of the mesh portion (830) of the first receiving body (821) and the second receiving body (823) to the outside of the inner filter according to the movement of the pressing portion (860).

[0173] Meanwhile, as the pressing part (860) moves to the outside of the inner filter (800), the lint moved by the first brush (875) and the second brush (876) moves to the outside of the inner filter (800) beyond the inclined surface (8221) of the lint protrusion (822) formed on the reinforcing rib of the first receiving body (821) and the second receiving body (823).

[0174] Here, the inclined surface (8221) of the lint protrusion (822) formed on the reinforcing rib (8211, 8231) is formed to be inclined so that the outer direction of the inner filter faces upward, and the lint moved by the first brush (875) or the second brush (876) passes over the inclined surface (8221) and is loaded on the inner outer side of the inner filter (800).

[0175] In addition, when the pressing part (860) is moved to the outside of the inner filter (800) and then to the center of the inner filter (800), the lint that has moved to the outside of the inner filter (800) due to the movement of the first brush (875) and the second brush (876) can be moved back to the center of the inner filter (800).

[0176] Meanwhile, on the opposite side of the inclined surface (8221) of the lint protrusion (822) formed on the reinforcing rib (8211, 8231), a catch surface (8222) extending in a direction perpendicular to the reinforcing rib (8211, 8231) is formed, and when the pressing part (860) moves to the center of the internal filter (800), the lint moved by the first brush (875) and the second brush (876) is caught on the catch surface (8222) and remains on the outside of the internal filter (800).

[0177] Meanwhile, the internal filter according to one embodiment of the present invention may further include a separate auxiliary filter (850) mounted on the inner lower portion. Hereinafter, the mounting of the auxiliary filter (850) will be described in detail with reference to FIG. 9.

[0178] Figure 9 is a perspective view showing the installation of an auxiliary filter according to one embodiment of the present invention.

[0179] As illustrated in Fig. 9, a separate additional auxiliary filter (850) may be further provided at the lower portion of the internal filter at a position where the first receiving body (821) and the second receiving body (823) come into contact. The auxiliary filter (850) may have a mesh of a different size from the mesh portion formed in the first receiving body (821) and the second receiving body (823).

[0180] 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).

[0181] Here, the auxiliary filter frame (852) is formed in a rectangular shape with the upper and lower portions open, and the auxiliary filter frame (852) is formed so that it can be placed between the lower portions of the first receiving body (821) and the second receiving body (823).

[0182] In addition, a plurality of reinforcing ribs (854) 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) to support the auxiliary filter (850) so that it is spaced apart from the first receiving body (821) and the second receiving body (823) by a predetermined distance when the auxiliary filter (850) is seated between the lower parts of 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 (854) toward the lower parts of the first receiving body (821) and the second receiving body (823).

[0183] In addition, a lower lint protrusion (855) that performs the same function as the lint protrusion (855) described above may be further formed on the reinforcing rib (854). The lower lint protrusion (855) extends from the upper portion of the reinforcing rib (854) toward the inside of the first receiving body (821) and the second receiving body (823), and may extend to the lower portion of the brush body (874) of the brush portion (871) described above.

[0184] Here, the lower lint protrusion (855) may be formed to be spaced apart at regular intervals in the longitudinal direction of each reinforcing rib (854) of the auxiliary filter frame (852), as illustrated in FIG. 9. In addition, the lower lint protrusion (855) may be formed with an inclined surface (855a) that rises outward based on the center of the auxiliary filter (850), and a relatively vertical engaging surface (855b) may be formed with respect to the reinforcing rib (854) on the surface facing the outside of the auxiliary filter (850).

[0185] Meanwhile, when an auxiliary filter (850) is provided, the brush unit (871) may further be provided with a third brush (877) for cleaning lint filtered by the auxiliary filter (850). The third brush (877) may extend from the lower part of the brush body (874) of the brush unit to the inside of the auxiliary filter frame (852).

[0186] Meanwhile, the third brush (877) may be integrally formed by insert injection at the bottom of the brush body (874) of the brush portion (871) during the manufacturing of the brush body (874), or alternatively, may be provided to be detachably attached to the bottom of the brush body (874).

[0187] Here, the lower lint protrusions (855) are formed at regular intervals along the reinforcing ribs (854), and the third brush (877) of the brush portion (871) can be positioned to correspond to the interval formed by the lower lint protrusions (855).

[0188] Accordingly, the lower lint protrusion (855) formed on the reinforcing rib (854) of the auxiliary filter frame (852) causes the lint moved by the third brush (877) of the brush portion (871) to move over the inclined surface (855a) of the lower lint protrusion (855) to the outside of the auxiliary filter (850) when the brush portion (871) moves toward the outside of the internal filter (800), and when the brush portion (871) moves toward the center of the auxiliary filter (850), the lint is caught on the catch surface (855b) of the lint protrusion (855) so that the lint can be captured on both sides of the auxiliary filter (850).

[0189] Meanwhile, the internal filter according to one embodiment of the present invention may further include a lint accumulation display unit (816) for displaying the amount of lint compressed in the filtering space according to the compression unit on the support body (810). Hereinafter, the lint accumulation display unit (816) will be described in detail with reference to FIG. 10.

[0190] Fig. 10 is a perspective view showing a lint accumulation indicator of an internal filter according to the present invention.

[0191] In the case of the compression unit (860) as described above, as the moving unit (862) reciprocates along the moving axis (861) inside the first and second receiving bodies (821, 823) of the internal filter (800), lint moved by the brush unit (871) of the compression unit (860) accumulates on both sides of the inside of the first and second receiving bodies (821, 823).

[0192] Accordingly, to enable the user to check the amount of lint accumulated in the internal filter (800), an accumulation display portion (816) for indicating the amount of lint accumulated can be formed on both adjacent sides of the moving groove (814) formed in the support body (810) of the internal filter (800).

[0193] Specifically, on one side of the support body (810) where the moving home (814) is formed, a stagnation indicator (816) that limits the moving distance of the moving part can be formed on both sides of the direction in which the moving part (862) of the pressing part (860) moves.

[0194] As described above, lint is accumulated on both sides of the first and second receiving bodies (821, 823) by the pressing unit (860) in the internal filter (800), and when the amount of lint accumulated on both sides of the first and second receiving bodies (821, 823) exceeds a certain amount, the brush unit (871) of the pressing unit is no longer moved by the accumulated lint. Therefore, an accumulation indicator unit (816) may be further formed on the support unit of the internal filter (800) at a position corresponding to the amount of lint accumulated in the internal filter (800).

[0195] Here, the position of the accumulation indicator (816) may be positioned differently depending on the internal volume of the internal filter (800), the accumulation space, etc. However, it may be formed at a shorter interval than the reciprocating movement distance of the moving knob (863) that moves along the moving groove (814) of the support body (810).

[0196] Hereinafter, an internal filter according to another embodiment of the present invention will be described in detail with reference to the attached drawings 11 to 13.

[0198] As illustrated, an internal filter (800) according to another embodiment of the present invention may include a support body (810) that is supported by being mounted on a mounting portion (138) and a receiving body (820) that extends downward from the support body (810) and is at least partially received in the external filter (900). The 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).

[0199] 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 portion of the open surface (812). The blocking ribs (811) may be provided to block the inflow of large materials such as clothing in addition to small foreign substances such as air or lint into the open surface (812). The blocking ribs (811) may be provided in the form of a mesh on the open surface (812).

[0200] Meanwhile, the upper surface of the support body (810) may include a coupling portion (815) 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 provided to be larger than the area of ​​the receiving body (820).

[0201] 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).

[0202] Meanwhile, the receiving body (820) is provided in a box shape, extends from the lower portion of the support body (810), and can provide a space for foreign substances to accumulate inside. The receiving body (820) can have a large area formed by through holes, and a mesh portion (830) that can filter foreign substances on the surface by being connected to the through holes can be installed.

[0203] Here, the mesh portion (830) may be provided in the form of a mesh that forms a through hole penetrating the receiving body (820). The mesh portion (830) may be provided to occupy most of the surface area of ​​the receiving body (820), and due to the mesh portion (830), the receiving body (820) may appear to have the shape of a frame that supports the mesh portion (830).

[0204] 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 (not shown) that is rotatably 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). Here, the second receiving body may be formed in a shape corresponding to the first receiving body (821) with the same configuration as the above-described embodiment of the present invention. Therefore, a detailed description of the second receiving body will be omitted.

[0205] Meanwhile, the first receiving body (821) and the second receiving body are provided to be separated from each other, so that the receiving body (820) can be opened internally. Accordingly, the user can remove foreign substances filtered through the first receiving body (821) and the second receiving body and accumulated in the receiving body (820).

[0206] Here, at least one reinforcing rib (8211) extending vertically in the first receiving body (821) and the second receiving body may be formed to reinforce the strength of the first receiving body (821) and the second receiving body, respectively. Accordingly, the mesh portion (830) may be positioned in a space formed by the reinforcing rib (8211) extending vertically from the inside of the first receiving body (821) and the second receiving body.

[0207] Meanwhile, a plurality of lint protrusions (822) are formed on each reinforcing rib (8211) of the first receiving body (821) and the second receiving body, through which the filtered lint is caught on the mesh portion of the first receiving body (821) and the second receiving body by the brush portion (871a) of the compression portion (860a) to be described later.

[0208] Here, the lint protrusions (822) may be formed to be spaced apart at regular intervals in the longitudinal direction of each reinforcing rib (8211). In addition, the lint protrusions (822) may be formed with an inclined surface that rises outward based on the center of the inner filter (800), and a relatively vertical engaging surface with respect to the reinforcing ribs (8211) may be formed on the surface facing the outside of the inner filter (800).

[0209] Meanwhile, the inclined surface and the engaging surface formed on the lint protrusion (822) of the reinforcing rib (8211) of the first receiving body (821) and the second receiving body have the same structure and function as the inclined surface (8221) and the engaging surface (8222) of the lint protrusion (822) formed on the first receiving body (821) in one embodiment of the present invention. Therefore, a detailed description thereof will be omitted.

[0210] Meanwhile, the lint protrusion (822) formed on the reinforcing rib (8211) moves along the inclined surface of the lint moved by the first brush (875a) and the second brush (876a) of the brush portion (871a) when the brush portion (871a) described later moves toward the outside of the internal filter (800), and when the brush portion (871a) moves toward the center of the internal filter (800), the lint can be caught on the catch surface of the lint protrusion (822) so that the lint can be captured on both sides of the internal filter.

[0211] Here, the lint protrusions (822) are formed at regular intervals along the reinforcing ribs (8211), and the first brush (875a) and the second brush (876a) of the brush portion (871a) can be arranged to correspond to the intervals formed by the lint protrusions (822). The first brush (875a) and the second brush (876a) of the brush portion (871a) will be described in detail when describing the brush portion (871a).

[0212] 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 is coupled are detachably coupled from each other.

[0213] The internal filter (800) may further include a connecting portion (840) connecting the first receiving body (821) and the second receiving body. The connecting portion (840) may be provided in the form of a rib extending in the width direction from the lower portions of the first receiving body (821) and the second receiving body. The connecting portion (840) may also function as a hinge for rotating the first receiving body (821) and the second receiving body.

[0214] Meanwhile, the filtering space formed by the first receiving body (821) and the second receiving body may further be provided with a pressing unit (860a) for pressing and moving the lint in the filtering space to both sides of the filtering space while moving the filtering space.

[0215] Meanwhile, a moving groove (814) is formed on one side of the support body (810) so that the compression part (860a) can be moved in the longitudinal direction of the support body (810), and the compression part (860a) can be provided so as to be able to move to both sides in the longitudinal direction of the filtering space while moving along the moving groove (814).

[0216] 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 may be formed in an arc shape corresponding to the shape of the open surface (812). That is, in the case of the filter unit (700), it is mounted on the mounting unit (138) formed on the inlet (133) of the first support unit (130), and it is preferable that the open surface (812) of the internal filter (800) extends in accordance with the shape of the inlet (133) and is formed in an arc shape.

[0217] Meanwhile, the compression unit (860a) includes a movable shaft unit (861a) arranged in the longitudinal direction of the support body on one side of the inside of the support body, a movable unit (862a) that is slidably connected to the movable shaft unit (861a) and partially exposed by a movable groove (814) formed in the support body (810), and a brush unit (871a) that is detachably connected to the movable unit (862a) and extends downward into the filtering space to scrape off lint collected in the mesh unit of the first receiving body (821) and the second receiving body.

[0218] The above-mentioned moving shaft part (861a) includes a moving shaft (8610a) arranged parallel to the length direction of the supporting body (810) on the inside of the open surface formed in the supporting body (810), a first axis support part (8611) in which one side of the moving shaft (8610a) is fixed and supported on one side of the inside of the receiving body (820), and a second axis support part (8612) in which the other side of the moving shaft (8610a) is fixed and supported on the other side of the inside of the receiving body (820).

[0219] Here, the first axis support (8611) and the second axis support (8612) are formed to face each other with respect to the moving axis (8610a), and the first axis support (8611) and the second axis support (8612) can be provided to face each other in the same shape. Therefore, the first axis support (8611) and the second axis support (8612) will be described together. However, the shape and function of the first axis support (8611) and the second axis support (8612) are not limited, and the function of supporting the moving axis (8610a) and the structure for supporting it inside the receiving body (820) may be varied as needed.

[0220] Meanwhile, the first axis support (8611) may be formed in the form of a bar that is detachably provided on one side of the inside of the receiving body (820). An axis insertion portion (8611a) into which one end of the moving shaft (8610a) is inserted and fixed may be formed on the upper portion of the first axis support (8611), and a catch (8611b) may be formed in the middle portion to fix the first axis support (8611) to the first receiving body (821) or the second receiving body constituting the receiving body (820).

[0221] Here, a catch groove (8213) into which a catch protrusion (8611b) of a first axis support member (8611) can be detachably inserted can be formed in the first receiving body (821) or the second receiving body constituting the receiving body (820). Specifically, a catch groove (8213) into which a catch protrusion (8611b) is inserted can be formed in an outer rib (8212) of the first receiving body (821) or the second receiving body at a position corresponding to the catch protrusion (8611b) of the first axis support member (8611).

[0222] Meanwhile, the moving part (862a) is provided to reciprocate within the interior of the receiving body (820) along the moving axis part (861a) within the inner surface of the supporting body (810). This moving part (862a) is provided with a rotation guide (864a) that rotates in an arc shape along the shape of the moving groove (814) formed in the supporting body (810), and an elevation guide (868a) that is rotatably connected to the rotation guide (864a) within the receiving body (820) and moves in a direction parallel to the moving axis (8610a) along the moving axis (8610a) in accordance with the rotation of the rotation guide (864a), and a brush part (871a) is elastically supported in the upper and lower directions at the lower portion.

[0223] Here, the rotation guide (864a) is formed with a rotation knob (8641a) that extends to the upper part of the open surface (812) by penetrating the moving groove (814) of the support body (810) at the top, and a guide groove (8642a) is formed on one side into which the longitudinal side of the moving groove (814) of the support body (810) is inserted to guide the rotation guide (864a) to move along the moving groove (814), and a rotation shaft groove (8651a) is formed on the other side into which the rotation shaft (8682a) of the lifting guide (868a) is rotatably inserted.

[0224] This rotation guide (864a) can be moved in an arc shape along the formation direction of the guide groove (8642a) as the user attaches and moves the rotation knob (8641a).

[0225] In addition, the lifting guide (868a) is formed in the shape of a bar extending in the vertical direction with an open bottom and an lifting space formed inside in which a brush portion (871a) moves. A moving shaft (8610a) is inserted into both upper sides of the lifting guide (868a), and an lifting slit (8681a) formed in the vertical direction so as to be able to be lifted and lowered with respect to the moving shaft (8610a) is formed. In addition, the open lower part of the lifting guide (868a) is provided so that a brush portion (871a) is inserted into the inside of the lifting guide (868a), and brush slits (8683a) may be further formed on the front and rear sides in which the first and second brushes (875a, 876a) of the brush portion (871a) to be described later can be moved.

[0226] This lifting guide (868a) is rotatably connected to the rotation guide (864a) so that the rotation guide (864a) moves in an arcuate direction along the moving groove (814) of the support body (810) when the user attaches and moves the rotation knob (8641a), and can be moved in accordance with the movement of the rotation guide (864a) in a vertically downward hanging state regardless of the arcuate movement of the rotation guide (864a).

[0227] In addition, the lifting guide (868a) is movably connected to the moving shaft (8610a) along the moving shaft (8610a), and when the lifting guide (868a) moves according to the rotation of the rotation guide (864a), it can move in a direction parallel to the moving shaft (8610a) along the moving shaft (8610a).

[0228] Here, the position of the lifting guide (868a) rotatably connected to the rotating guide (864a) can be changed in the up-and-down direction according to the rotation of the rotating guide (864a), and the moving shaft (8610a) is inserted into the lifting slit (8681a) of the lifting guide (868a), so that even if the position of the lifting guide (868a) changes in the up-and-down direction according to the movement of the rotating guide (864a), it can be moved left and right along the moving shaft (8610a) and raised and lowered in the up-and-down direction with respect to the moving shaft (8610a).

[0229] Meanwhile, the brush portion (871a) may be inserted into the lower portion of the lifting guide (868a) and provided to be elastically supported by the lower portion of the lifting guide (868a). Here, a separate spring (not shown) for elastically supporting the brush portion (871a) may be provided on the inner side of the lifting guide (868a), and the brush portion (871a) may be elastically supported downward of the lifting guide by the spring.

[0234] Meanwhile, the first brush (875a) and the second brush (876a) may be formed to extend from the brush body (874a) toward the inner surfaces of the first receiving body (821) and the second receiving body. The first brush (875a) and the second brush (876a) may move the filtered lint on the surface of the mesh portion (830) of the first receiving body (821) and the second receiving body to the outside of the inner filter according to the movement of the pressing portion (860a).

[0235] Meanwhile, as the pressing part (860a) moves to the outside of the inner filter (800), the lint moved by the first brush (875a) and the second brush (876a) moves to the outside of the inner filter (800) over the inclined surface of the lint protrusion (822) formed on the reinforcing rib of the first receiving body (821) and the second receiving body.

[0236] Here, the inclined surface of the lint protrusion (822) formed on the reinforcing rib (8211) is formed to be inclined so that the outer direction of the inner filter faces upward, and the lint moved by the first brush (875a) or the second brush (876a) goes over the inclined surface and is loaded on the inner and outer side of the inner filter (800).

[0237] In addition, when the pressing part (860a) is moved to the outside of the inner filter (800) and then moved to the center of the inner filter (800), the lint that has moved to the outside of the inner filter (800) due to the movement of the first brush (875a) and the second brush (876a) can be moved back to the center of the inner filter (800).

[0238] Meanwhile, on the opposite side of the inclined surface of the lint protrusion (822) formed on the reinforcing rib (8211), a catch surface is formed that extends in a direction perpendicular to the reinforcing rib (8211), and when the pressing portion (860a) moves to the center of the internal filter (800), the lint moved by the first brush (875a) and the second brush (876a) is caught on the catch surface and remains on the outside of the internal filter (800).

[0239] Meanwhile, in the internal filter (800) according to another embodiment of the present invention, a separate auxiliary filter (not shown) may be further mounted on the inner lower portion of the internal filter (800) as in one embodiment of the present invention. In addition, a third brush (not shown) for capturing lint of the auxiliary filter may be further provided on the lower portion of the brush body (874a). The auxiliary filter and the third brush may have the same configuration and function as in one embodiment of the internal filter described above, and a detailed description thereof will be omitted.

[0240] In addition, the internal filter (800) according to another embodiment of the present invention may further be formed with a lint accumulation display unit (not shown) to display the amount of lint compressed in the filtering space by the compression unit (860a) on the support body (810). The lint accumulation display unit may have the same configuration and function as the embodiment of the internal filter (800) described above, and a detailed description thereof will be omitted.

[0241] Hereinafter, an internal filter according to another embodiment of the present invention will be described in detail with reference to the attached drawings 14 to 16.

Here, the second receiving body may be formed in a shape corresponding to the first receiving body with the same configuration as the above-described embodiment of the present invention. Therefore, a detailed description of the second receiving body will be omitted.

[0250] Meanwhile, the first receiving body (821) and the second receiving body are provided to be separated from each other, so that the receiving body (820) can be opened internally. Accordingly, the user can remove foreign substances filtered through the first receiving body (821) and the second receiving body and accumulated in the receiving body (820).

[0251] Here, at least one reinforcing rib (8211) extending vertically in the first receiving body (821) and the second receiving body may be formed to reinforce the strength of the first receiving body (821) and the second receiving body, respectively. Accordingly, the mesh portion (830) may be positioned in a space formed by the reinforcing rib (8211) extending vertically from the inside of the first receiving body (821) and the second receiving body.

[0252] Here, the reinforcing ribs (8211) formed in the first receiving body (821) and the second receiving body may be formed radially with respect to the center of rotation of the brush portion (871b) to be described later. These reinforcing ribs (8211) may be formed to be spaced apart from the outside of the first receiving body (821) and the second receiving body with respect to the center of the receiving body.

[0253] Meanwhile, a plurality of lint protrusions (822) are formed on each reinforcing rib (8211) of the first receiving body (821) and the second receiving body, through which the filtered lint is caught on the mesh portion of the first receiving body (821) and the second receiving body by the brush portion (871b) of the compression portion (860b) to be described later.

[0255] Meanwhile, the lint protrusion (822) formed on the reinforcing rib (8211) moves the lint moved by the first brush (785b) and the second brush of the brush portion (871b) along the inclined surface when the brush portion (871b) described later moves toward the outside of the internal filter (800), and when the brush portion (871b) moves toward the center of the internal filter (800), the lint can be caught on the catch surface of the lint protrusion (822) so that the lint can be captured on both sides of the internal filter.

[0256] Here, the lint protrusions (822) are formed at regular intervals along the reinforcing ribs (8211), and the first brush (785b) and the second brush of the brush portion (871b) can be arranged to correspond to the intervals formed by the lint protrusions (822). The first brush (785b) and the second brush of the brush portion (871b) will be described in detail when describing the brush portion (871b).

[0257] 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 is coupled are detachably coupled from each other.

[0258] In addition, the internal filter (800) may further include a connecting portion (840) connecting the first receiving body (821) and the second receiving body. The connecting portion (840) may include a first hinge portion (841) provided at the lower portion of the first receiving body (821) and a second hinge portion (not shown) provided at the lower portion of the second receiving body. Meanwhile, the first hinge portion (841) formed at the first receiving body (821) may be formed to extend from the lower portion of the lower mesh portion (8223) when an auxiliary mesh portion (830) is formed at the first receiving body (821).

[0259] Here, the first hinge portion (841) and the second hinge portion are formed to extend from the lower portions of the first receiving body (821) and the second receiving body, and can extend in directions facing each other. In addition, a hinge groove (8411) can be formed in the first hinge portion (841), and a hinge protrusion (not shown) inserted into the hinge groove (8411) can be formed in the second hinge portion.

[0260] Accordingly, the first receiving body (821) and the second receiving body (823) can be rotatably coupled with each other by having the hinge projection of the second receiving body axially centered on the hinge groove (8411) of the first receiving body (821) according to the fastening of the first hinge portion (841) and the second hinge portion of the connecting portion (840).

[0261] Meanwhile, the filtering space formed by the first receiving body (821) and the second receiving body may further be provided with a pressing unit (860b) for pressing and moving the lint in the filtering space to both sides of the filtering space while moving the filtering space.

[0262] Meanwhile, a moving groove (814) is formed on one side of the support body (810) so that the compression part (860b) can be moved in the longitudinal direction of the support body (810), and the compression part (860b) can be provided so as to be able to move to both sides in the longitudinal direction of the filtering space while moving along the moving groove (814).

[0263] 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 may be formed in an arc shape corresponding to the shape of the open surface (812). That is, in the case of the filter unit (700), it is mounted on the mounting unit (138) formed on the inlet (133) of the first support unit (130), and it is preferable that the open surface (812) of the internal filter (800) extends in accordance with the shape of the inlet (133) and is formed in an arc shape.

[0264] Here, a lower mesh portion (8223) may be further formed at the lower portion of the first receiving body (821) or the second receiving body to connect the first receiving body (821) and the second receiving body while filtering lint moving to the lower portion of the receiving body (820).

[0265] Meanwhile, the lower mesh portion (8223) may be formed in a frame shape in which a hollow space is formed, and a number of lower reinforcing ribs may be further formed in the hollow space to maintain the shape of the lower mesh portion.

[0266] Meanwhile, the lower mesh portion (8223) may further include a lower frame (8223a) positioned in the lower space formed by the first receiving body (821) and the second receiving body when the first receiving body (821) and the second receiving body are fastened, and a lower mesh (8223b) provided in the lower open space of the lower frame (8223a). Here, the lower mesh portion (8223) may have a mesh of a different size from the mesh portions formed in the first receiving body (821) and the second receiving body.

[0267] Accordingly, the lower frame (8223a) is formed in a rectangular shape with the upper and lower parts open, and the lower frame (8223a) is formed at the lower part of the first receiving body (821), so that when the second receiving body is fastened to the first receiving body (821), a filtering space can be formed in the first receiving body (821) like the second receiving body.

[0268] Meanwhile, the lower mesh portion (8223) may be formed as a curved surface having a predetermined curvature to correspond to the rotation radius of the brush portion (871b) to be described later. That is, in the case of the movable groove (814) to which the brush portion (871b) is movably coupled, it may be formed in an arc shape centered on the inlet (133).

[0269] Accordingly, the brush portion (871b) movably connected to the moving home (814) can rotate along the curvature of the moving home. That is, the brush portion (871b) that rotates along the moving home (814) can rotate to have a fan-shaped rotation area within the receiving body (820).

[0270] Meanwhile, if the lower mesh portion (8223) is formed in a straight line, it is impossible to remove lint by the brush portion (871b) on the outer side of the rotation radius of the brush portion (871b) having a fan-shaped rotation area. Therefore, it is preferable that the lower mesh portion (8223) be formed to have a predetermined curvature corresponding to the rotation radius of the brush portion (871b).

[0271] In addition, a plurality of lower reinforcing ribs (8223c) are formed on the inside of the lower frame (8223a) to maintain the shape of the lower frame (8223a), and a lower lint protrusion (8223d) that performs the same function as the lint protrusion (8222) described above may be further formed on the lower reinforcing ribs (8223c) of the lower frame (8223a).

[0272] Here, the lower lint protrusion (8223d) extends from the upper portion of the reinforcing rib (8211) to the inside of the first receiving body (821) and the second receiving body, and can extend to the lower portion of the brush body (874b) of the brush portion (871b) described above.

[0273] Here, the lower lint protrusions (8223d) may be formed to be spaced apart at regular intervals in the longitudinal direction of each reinforcing rib (8211) of the lower frame (8223a). In addition, the lower lint protrusions (8223d) may be formed with an inclined surface that extends upward outward based on the center of the lower mesh portion (8223), and a relatively vertical engaging surface may be formed with respect to the reinforcing ribs (8211) on the surface facing the outside of the lower mesh portion (8223).

[0274] Meanwhile, the inclined surface and the catch surface formed on the lower lint protrusion (8223d) have the same structure and function as the inclined surface (8221) and the catch surface (8222) of the lint protrusion (822) formed on the first receiving body (821) in one embodiment of the present invention. Therefore, a detailed description thereof will be omitted.

[0275] Meanwhile, the compression part (860b) is slidably fastened along the shape of the movable groove (814) and includes a movable part (862b) that is partially exposed to the outside of the movable groove (814) formed in the support body (810) and has a brush part (871b) fastened to the lower part, and a brush part (871b) that is detachably fastened to the movable part (862b) 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.

[0276] Here, the moving part (862b) is provided so as to reciprocate in a fan shape within the receiving body (820) along the moving groove (814) of the supporting body (810). The moving part (862b) is formed with a rotation knob (864b) extending to the upper portion of the open surface (812) by penetrating the moving groove (814) of the supporting body (810) at the upper portion, a guide groove (not shown) that is movably connected to the moving groove (814) formed in the supporting body (810) and guides the moving part (862b) to rotate in an arc shape, and a brush connection part (867b) located within the receiving body (820) and to which the brush part (871b) is connected.

[0277] This moving part (862b) rotates in an arc shape along the direction of formation of the moving home (814) as the user moves it by attaching the rotation knob (864b), and the brush part connected to the brush connection part (867b) rotates in a fan shape to capture the lint filtered in the mesh part of the first receiving body (821) and the second receiving body.

[0278] Meanwhile, the brush portion (871b) is connected to and joined with the brush fastening portion (867b) and can move in conjunction with the rotation of the moving portion. In addition, the brush portion (871b) can be provided with an insertion portion (872b) connected to the brush fastening portion (867b), a brush body (874b) extending from the lower portion of the insertion portion (872b) to the filtering space of the internal filter (800), and a plurality of brushes provided on the brush body (874b).

[0279] Here, the insertion part (872b) of the brush part (871b) is detachably fastened to the brush fastening part on the inside of the internal filter, and the brush part (871b) that is worn out or damaged during long-term use of the compression part (860b) can be replaced.

[0280] Here, the insertion portion (872b) is formed in a shape corresponding to the insertion space of the brush fastening portion (867b), and the brush body (874b) is formed by extending to the filtering space formed by the first receiving body (821) and the second receiving body of the internal filter (800) at the bottom.

[0281] Meanwhile, the brush body (874b) is formed to have one side facing the mesh portion of the first receiving body (821) and the other side facing the mesh portion of the second receiving body, and a first brush (785b) that contacts the mesh portion of the first receiving body (821) is formed on one side, and a second brush (not shown) that contacts the mesh portion of the second receiving body may be provided on the other side.

[0282] Meanwhile, in the case of the first brush (785b) and the second brush of the brush body (874b) described above, they may be integrally formed by insert injection during the manufacturing of the brush body (874b), or alternatively, they may be detachably attached separately to the brush body (874b).

[0283] Meanwhile, the first brush (785b) and the second brush may be formed to extend from the brush body (874b) toward the inner surfaces of the first receiving body (821) and the second receiving body. The first brush (785b) and the second brush may move the filtered lint on the surface of the mesh portion (830) of the first receiving body (821) and the second receiving body to the outside of the inner filter (800) according to the movement of the pressing portion (860b).

[0284] Meanwhile, as the compression unit (860b) reciprocates to both sides of the internal filter (800), the lint moved by the first brush (785b) and the second brush moves to the outside of the internal filter (800) over the inclined surface of the lint protrusion (822) formed on the reinforcing rib of the first receiving body (821) and the second receiving body.

[0285] Here, the inclined surface of the lint protrusion (822) formed on the reinforcing rib (8211) is formed to be inclined so that the outer direction of the inner filter faces upward, and the lint moved by the first brush (785b) or the second brush goes over the inclined surface and is loaded on the inner and outer side of the inner filter (800).

[0286] In addition, when the pressing part (860b) is moved to the outside of the inner filter (800) and then to the center of the inner filter (800), the lint that has moved to the outside of the inner filter (800) due to the movement of the first brush (785b) and the second brush can be moved back to the center of the inner filter (800).

[0287] Meanwhile, on the opposite side of the inclined surface of the lint protrusion (822) formed on the reinforcing rib (8211), a catch surface is formed that extends in a direction perpendicular to the reinforcing rib (8211), and when the pressing portion (860b) moves to the center of the internal filter (800), the lint moved by the first brush (785b) and the second brush is caught on the catch surface and remains on the outside of the internal filter (800).

[0288] Meanwhile, when the first receiving body (821) is provided with a lower mesh portion (8223), the brush body (874b) of the brush portion (871b) may further be provided with a third brush (877b) for cleaning lint filtered in the lower mesh portion (8223). The third brush (877b) may extend from the lower portion of the brush body (874b) of the brush portion (871b) toward the lower mesh (8223b) of the lower mesh portion (8223).

[0289] Meanwhile, the third brush (877b) may be integrally formed by insert injection at the bottom of the brush body (874b) of the brush portion (871b) during the manufacturing of the brush body (874b), or alternatively, may be provided to be detachably attached to the bottom of the brush body (874b).

[0290] Here, the lower lint protrusions (8223d) are formed at regular intervals along the reinforcing ribs (8211), and the third brush (877b) of the brush portion (871b) can be arranged to correspond to the interval formed by the lower lint protrusions (8223d).

[0291] Accordingly, the lower lint protrusion (8223d) formed on the reinforcing rib (8211) of the lower frame (8223a) causes the lint moved by the third brush (877b) of the brush portion (871b) to move along the inclined surface of the lower lint protrusion (8223d) to the outside of the lower mesh portion (8223) when the brush portion (871b) moves toward the outside of the inner filter (800), and when the brush portion (871b) moves toward the center of the lower mesh portion (8223), the lint is caught on the catch surface of the lint protrusion (822) so that the lint can be captured on both sides of the lower mesh portion (8223).

[0292] In addition, the internal filter (800) according to another embodiment of the present invention may have a brush portion (871b) that can be elastically supported toward the lower mesh portion (8223) with respect to the moving portion (862b) as in another embodiment of the present invention.

[0293] That is, although not shown, a separate tension spring (not shown) may be further provided to elastically support the insertion portion (872b) of the brush portion (871b) toward the lower mesh portion (8223) in the brush fastening portion (867b) of the moving portion (862b).

[0294] That is, the insertion portion (872b) of the brush portion (871b) can be movably fastened to the brush fastening portion (867b) of the moving portion (862b) in the radial direction of the moving portion (862b), and a tension spring that elastically supports the insertion portion (872) in a direction away from the brush fastening portion (867b) can be provided between the brush fastening portion (867b) and the insertion portion (872b).

[0295] Accordingly, as the moving part (862b) of the pressing part (860b) rotates, the brush body (874b) of the brush part (871b) that rotates together with the moving part (862b) presses the lower mesh part (8223) side, thereby allowing the lint filtered in the lower mesh part (8223) to be captured in the direction of the rotation of the pressing part.

[0296] In addition, the internal filter (800) according to another embodiment of the present invention may further be formed with a lint accumulation display unit (not shown) to display the amount of lint compressed in the filtering space by the compression unit (860b) on the support body (810). The lint accumulation display unit may have the same configuration and function as in the above-described embodiment of the present invention, and a detailed description thereof will be omitted.

[0297] 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.
