    [050] Clothes treatment equipment capable of drying clothes can be classified into two categories based on the airflow methods to supply air at a high temperature (hot air) to the clothes: an exhaust treatment equipment and circulation treatment equipment (condensation type). In the circulation treatment equipment, the air in an accommodation space, where the clothes are placed, is circulated so that the air discharged from the accommodation space is dehumidified and heated and the dehumidified and heated air is supplied again to the accommodation space. In extractor type laundry treatment equipment, heated air is supplied to an accommodation space so that the air discharged from the accommodation space is not circulated and is discharged out of the laundry treatment equipment.
    [051] In the case of circulation treatment equipment, as the air discharged from the accommodation space is dehumidified and heated by a heat exchanger and is then fed back into the accommodation space, if foreign substances are not removed from the room. air discharged from the accommodation space, foreign substances accumulate in the heat exchanger and thus the efficiency of the heat exchange may be reduced.
    [052] In the case of extractor type laundry treatment equipment, if the air is discharged from the accommodation space without being filtered, lint or dust present in the discharged air can be taken to an internal space provided in the laundry treatment equipment.
    [053] Therefore, it may be desirable to filter the air discharged from an accommodation space for the laundry treatment equipment capable of drying clothes. Consequently, a filter is provided in a laundry treatment equipment to filter foreign substances from the air exhausted from the accommodation space. A mechanism can be provided in the laundry equipment that allows the filter to be cleaned automatically, thus eliminating the need for the user to check the condition of the filter before or after the laundry equipment is used.
    [054] FIG. 1 illustrates an example of a laundry treatment equipment. Hereinafter, with reference to FIG. 1, a general configuration of the laundry equipment will be described.
    [055] A laundry treatment equipment 100 in accordance with the present disclosure includes a cabinet 1 forming the external appearance of the laundry treatment equipment 100 and an accommodation space 2 formed in cabinet 1 to receive the clothing.
    [056] Accommodation space 2 includes a drum 21 to provide a space to receive an object to be dried, eg, clothes, and a drum 21 with a cylindrical shape equipped with open front and rear surfaces.
    [057] A front support piece 25 to support the open front surface of the drum 21 is provided on the front portion of the drum 21, and a rear support piece 27 to support the open back surface of the drum 21 is provided on the rear portion of the drum. 21.
    [058] The front support piece 25 is equipped with an opening 251 through which the clothes are placed on the drum 21 or removed from the drum 21, and the opening 251 is opened and closed by a door 3 rotationally provided in the cabinet 1.
    [059] The door 3 includes a door glass 31 extended towards the opening 251. The glass of the door 31 guides the laundry to be washed in the direction of the door 3 into the interior of the drum 21 during the rotation of the drum 21 as well as allows a user to look inside the drum 21 during operation of the laundry equipment.
    [060] The rear support part 27 is equipped with a supply port 271 through which external air is introduced in the drum 21, and a supply port 271 is connected to a supply port 43 which will be described later.
    [061] The drum 21 supported by a front support piece 25 and the rear support piece 27 is rotated by means of a drum motor 213 and a belt 215, and elevators 211 that facilitate the rolling of an object to be dried as well are provided on the inner circumferential surface of the drum 21.
    [062] The laundry treatment equipment in accordance with the present disclosure also includes a duct unit 4 and an air supply unit 5 to supply air (eg hot air) for the clothes to be washed received in the drum 21 .
    [063] Duct unit 4 includes a discharge duct 41 to discharge air from drum 21 and a supply duct 43 to supply air to the interior of drum 21.
    [064] The discharge duct 41 is equipped with a suction port 411 into which the air discharged from the drum 21 is introduced. The supply duct 43 communicates with a discharge duct 41 and is connected to the supply port 271 of the rear support part 27, thus supplying air that has passed through the air supply unit into the interior of the drum 21.
    [065] In the case of a circulation treatment equipment, the discharge duct 41 and a supply duct 43 may be connected together to form a channel. The air supply unit 5 includes a fan 57 for blowing air, a condensing piece for dehumidifying the air flowing inside the duct unit 4, and a heating piece for heating the dehumidified air.
    [066] The fan 57 is an air circulation device that causes the air in the drum 21 to be introduced into the discharge duct 41. The fan 57 can be rotated by means of the drum motor 213.
    [067] When the fan 57 is rotated, the air in the duct unit 4 flows into the drum 21. When the air in the duct unit 4 is introduced into the drum 21, the air in the drum 21 is introduced into the discharge duct 41 through suction port 411.
    [068] While the air introduced in the discharge duct 41 flows towards the supply duct 43 through an air supply unit 5, the air is dehumidified and heated, thereby drying the clothes in the drum 21.
    [069] In circulation-type clothing treatment equipment, foreign substances, such as lint, can be discharged from the clothes during a drying process, and foreign substances discharged from the clothes are circulated along the duct unit 4. Therefore , if foreign substances are not filtered out of the air discharged from drum 21, foreign substances stick to the surface of a heat exchanger, such as the condensing part or the heating part, thus reducing the drying efficiency of the treatment equipment with clothes.
    [070] In an attempt to solve the problem, the clothing treatment equipment in accordance with the present disclosure also includes a filter set 6 to filter foreign substances from the air circulated along the duct unit 4 to reduce the fall of an air flow rate due to foreign substances, as well as a decrease in drying efficiency.
    [071] The filter set 6 can be detachable in the suction hole 411 of the discharge duct 41. In this case, a user can separate the filter set 6 from the laundry equipment or connect the filter set 6 to the laundry equipment after opening the door 3.
    [072] The connection structure described above between the filter set 6 and a discharge duct 4 is provided in the circulation treatment equipment for drying clothes. However, this connection structure between the filter set 6 and a discharge duct 4 can be applied to a laundry treatment equipment capable of washing and drying clothes and an exhaust type laundry treatment equipment for the sole purpose of drying. clothes.
    [073] That is, the filter set described above 6 can be applied to an extractor type laundry treatment equipment (for the purpose of drying clothes only) shown in FIG. 22.
    [074] In the extractor type laundry treatment equipment as shown in FIG. 22, the air outside an accommodation space is heated by an air supply unit 5 and heated air is supplied inside the accommodation space (eg drum 21), so that air discharged from the accommodation space 21 is discharged out of the laundry equipment.
    [075] Therefore, in the case of extractor type laundry treatment equipment, the air supply unit 5 is supplied separately in the discharge duct 41 to discharge air from the drum 21 and a supply duct 43 to supply air to the interior of the drum 21.
    [076] In this case, the filter assembly 6 is detachably coupled to the suction port 411 of the discharge duct 41, and a heating part and a condensing part of the air supply unit 5 are provided in the supply duct. 43. Although FIG. 22 illustrate supply duct 43 as communicating with the outside of cabinet 1, supply duct 43 may be provided to supply air within cabinet 1 to the interior of drum 21.
    [077] FIG. 23 illustrates a circulation treatment equipment capable of washing and drying clothes.
    [078] As shown in FIG. 23, in some implementations, a tub 23, where a drum 21 is provided, and which stores washing water, is equipped inside a cabinet 1. Therefore, in the laundry treatment equipment capable of washing and drying clothes, a space for Accommodation 2 includes bowl 23 and drum 21.
    [079] To load and remove clothes from the accommodation space 2, the bowl 23 is equipped with a bowl opening 231 and a drum 21 is equipped with a drum opening 217 communicating with the opening of the bowl 231.
    [080] In addition, this structure includes a supply hose 18 to supply wash water to bowl 23 and a drain hose 19 to drain bowl 23. Supply hose 18 is connected to bowl 23 by means of a detergent 17.
    [081] In some implementations, a space between the bowl 23 and a cabinet 1 is sealed by a joint 233, and a discharge duct 41 is connected to the front surface of the bowl 23 and a supply duct 43 is connected to the rear surface of the bowl 23.
    [082] However, unlike FIG. 23, supply duct 43 may be located in any position where air is supplied to vat 23 through the front surface of vat 23.
    [083] A filter set 6 can be detachably provided in the suction hole 411 of the discharge duct 41. A drum motor 213 for turning the drum 21 can be provided to simultaneously turn a fan 57 and a drum 21 of the same so that in FIG. 1 or be provided to rotate the drum 21 alone as shown in FIG. 23.
    [084] In the previous case, a drive pulley is provided on drum motor 213 and a driven pulley connected to the drive pulley by the belt is provided on the rear surface of bowl 23. Here, the driven pulley is attached to the rear surface of the drum 21 by a rotating shaft.
    [085] Although not shown in the drawings, in the case of an extractor type laundry treatment equipment capable of washing and drying clothes, a supply duct and a discharge duct are separated from each other in the same way as in FIG. 22 and thus a detailed description of them will be omitted.
    [086] FIGS. 2A, 2B and FIG. 3 illustrate an example of a filter assembly. The filter assembly 6 includes a housing 61 detachably provided in the suction port 411 of the discharge duct 41, an inflow surface 63 communicating with a suction port 411 and allowing air to be introduced into the housing 61, units filter 65 to filter foreign substances, such as lint, introduced into housing 61 and a foreign substance removal unit 67 to move remaining foreign substances in filter units 65 to one side (eg, a storage space) from inside the housing 61 and to compress foreign substances.
    [087] enclosure 61 includes a first part of enclosure 611 and a second part of enclosure 612 which are connected together by a hinge 613, as shown in FIGS. 2A and 2B.
    [088] In this case, the inflow surface 63 may be provided on the upper surface made of the first part of the housing 611 and the second part of the housing 612. FIGs. 2A and 2B illustrate the inflow surface 63 as provided on the upper surface of the first part of housing 611.
    [089] The inflow surface 63 may be formed in a shape corresponding to the shape of the suction port 411 provided in the discharge duct 41 and a plurality of inflow holes 631 to guide the air introduced in the suction port 411 into the interior of the casing 61.
    [090] Filter units 65 are used to remove foreign substances from the air discharged from the accommodation space and to supply air, from which foreign substances are removed, to duct unit 4. Filter units 65 are supplied in at least least one surface of the housing 61.
    [091] That is, filter units 65 may be provided as a form of mesh that removes foreign substances from the air introduced into housing 61 and allows air, from which foreign substances are removed, to flow along the duct unit 4 .
    [092] The filter set 6 in accordance with the present disclosure includes a pair of filters respectively supplied at the two opposite ends of the inflow surface 63 to increase a filtering capacity (eg, an amount of air passing through the filter set 6 ).
    [093] That is, filter units 65 may be a first filter 651 provided in the first part of housing 611 and a second filter 653 provided in the second part of housing 612.
    [094] In this case, since the first part of housing 611 and the second part of housing 612 are connected by hinge 613, if a large amount of foreign substances are stored within filter set 6, a user separates the first part from the housing 611 and the second part of housing 612 from each other and removes foreign substances stored within filter assembly 6.
    [095] The foreign substance removal unit 67 is provided rotationally within the housing 61 and serves to move the remaining foreign substances in the filter units 65 to one side within the housing 61 and to compress the foreign substances.
    [096] For this purpose, the foreign substance removal unit 67 includes a brush 671 that contacts filter units 65, a brush structure 673 to which brush 671 is attached, a axis of rotation of brush 675 to receive propulsion energy from an engine 7 (see, for example, Figures 4A and 4B), which are described in more detail later, and to transmit the received propulsion energy to the brush frame 673, and a insertion of shaft 677 provided in brush frame 673 so that the axis of rotation of brush 675 is inserted into the insertion hole of shaft 677.
    [097] For example, the rotation axis of the brush 675 passes through the filter unit 65 and is inserted into the insertion hole of the axis 677 of the brush structure 673, and a driven gear 6751 located on the outside of the housing 61 is connected to the axis of rotation of the brush 675, as shown in FIG. two.
    [098] Drive gear 6751 engages drive gear 73 provided on motor 7 (see, for example, FIGS. 4a and 4b) provided on the outside of housing 61.
    [099] In an alternative implementation, the foreign matter removal unit 67 includes an air generator that blows air over the filter unit 65. The air generator blows air over the filter unit so that air is only blown over a portion of the air covered by the first filter 651 and a second filter 653. Foreign substances are removed from the portion of the filter unit 65 over which the air is blown by the air generator, so that foreign substances are moved to one side inside the housing 61 and compressed by the force of the air blown by the air generator.
    [0100] Unlike what is shown in FIG. 2, a gap between the first part of the housing 611 and the second part of the housing 612 can be gradually narrowed in the direction of the inflow surface 63 to the hinge 613 (see FIG. 3). This serves to allow foreign substances to be stacked in the lower portion of the casing 61, as the air introduced in the casing 61 through the inflow surface 63 is discharged out of the casing 61 via the first filter 651 and second filter 653.
    [0101] As shown in FIGs. 4A and 4B, the motor 7 includes a motor rotation shaft 71 and a control gear 73 connected to the motor rotation shaft 71. The motor 7 can be supplied in a position in which the driven gear 6751 is engaged in the driving gear. command 73 when the filter set 6 is inserted into the suction port 411 of the discharge duct 4.
    [0102] Therefore, when the motor 7 is operated, the driven gear 6751 is rotated by the driven gear 73 and a axis of rotation of the brush 675 is rotated by the driven gear 6751. Since the axis of rotation of the brush 675 is fixed on the shaft insertion hole 677 provided in brush frame 673, brush 671 attached to brush structure 673 is also rotated within housing 61 when motor 7 is rotated.
    [0103] Additionally, the control gear 73 and the control gear 6751 can be connected by means of a connection gear 75, as shown in FIG. 4B.
    [0104] This connection structure serves to transmit propulsion energy from the motor 7 to the foreign substance removal unit 67 if it is difficult to engage the control gear 73 provided on the motor rotation shaft 71 directly with the driven gear 6751 due to a structural arrangement of the laundry treatment equipment.
    [0105] In some implementations, the rotation axis of the motor 71 is provided in a position separate from the insertion direction (X) of the rotation axis of the 675 brush by an angle designated θl. That is, the axis of rotation of the motor 71 and a axis of rotation of the brush 675 cannot be supplied in a straight line.
    [0106] The filter assembly 6 is inserted into the discharge duct 41 through the suction port 411. Here, if the driven gear 6751 and the driven gear 73 are located in a straight line, the teeth of the driven gear 73 and the teeth of the 6751 driven gear may not engage correctly with each other.
    [0107] Although the control gear teeth 73 and the control gear teeth 6751 are not correctly engaged with each other, when the filter assembly 6 is inserted into the discharge duct 41, the control gear teeth 73 and the teeth of the 6751 driven gear may be damaged. The structure described above can resolve this issue.
    [0108] That is, when the center of rotation of drive gear 73 and a center of rotation of driven gear 6751 are separated from each other by a distance in the Y direction perpendicular to the insertion direction X of filter set 6, the problem above can be resolved.
    [0109] The angle 01 between the axis of rotation of the motor 71 and a axis of rotation of the brush 675 may be in the range of approximately 10 to 80 degrees in relation to the insertion direction of the filter set 6, and preferably in the range of 30 at 60 degrees.
    [0110] If command gear 73 and command gear 6751 are connected by connection gear 75, as shown in FIG. 4B, the center of rotation of the connecting gear 75 and a center of rotation of the driven gear 6751 can be connected in the angle range above.
    [0111] Hereinafter, a structure for fixing the connection between the filter assembly 6 and a discharge duct 41 will be described with reference to FIG. 5 and FIGs. 6A and 6B.
    [0112] Since the foreign substance removal unit 67 rotated by the propulsion energy transmitted from the engine 7 is provided inside the housing 61, as described above, if the filter assembly 6 is not fixed in the suction port 411, the assembly filter 6 can be separated from the suction port 411 when the engine 7 is operated.
    [0113] That is, drive gear 6751 receives propulsion energy transmitted from drive gear 73 when motor 7 is rotated, and if filter set 6 is not attached to suction port 411, filter set 6 can be separated from the discharge duct 41. Therefore, a structure can be used to prevent the housing 61 from being separated from the suction port 411.
    [0114] For this purpose, the housing 61 of the filter assembly 6 can be provided to apply pressure to the interior of the discharge duct 41 through the glass 31 when the door 3 is closed.
    [0115] That is, the housing 61 may also include a protrusion 614 projected from the inflow surface 63, as shown in FIG. 5.
    [0116] In this case, the protrusion may be long enough to contact the glass 31 when door 3 is closed and has the same radius of curvature as the radius of curvature of glass 31.
    [0117] Additionally, the protrusion may be tilted at an angle C designated to not interrupt the opening and closing of door 3.
    [0118] The protrusion may be a handle 614 equipped with a space to receive a user's hand (see, for example, Figures 4A and 4B). The handle 614 serves to facilitate the coupling and uncoupling of the filter assembly from the discharge duct 41, as well as to restrict the movement of the filter assembly 6.
    [0119] The filter set 6 may also include a housing securing the unit 615 to connect the filter set 6 to the suction port 411 (see, for example, FIG. 6A).
    [0120] As shown in FIG. 6A, the housing securing the unit 615 includes a lever 6151 located within the space provided by the handle 614 and hooks 6153 respectively provided at the two opposite ends of the lever 6151.
    [0121] In this case, grooves of the hooks to receive the hooks 6153 or hooks of the duct to fix the hooks 6153 are preferably provided in the discharge duct 41.
    [0122] The lever 6151 folds up to the space provided by the handle 614 and is supported in an elastic way by elastic members, such as springs 6155, as shown in FIG. 6B.
    [0123] Therefore, when a user opens the door, rotates lever 6151 to separate hooks 6153 from the hook grooves provided in the discharge duct 41 and raises housing 61 using handle 614, filter assembly 6 can be separated from discharge duct 41.
    [0124] Hereinafter, a detailed structure of the foreign substance removal unit 67 will be described with reference to FIGs. 7A and 7B and FIGs. 8A to 8C.
    [0125] The foreign substance removal unit 67 can be configured so that brush 671 is inserted into a hole provided in the center of brush structure 673.
    [0126] In this case, brush 671 may have a length equal to or greater than a radius of the filter unit 65.
    [0127] Additionally, brush 671 may be formed of an elastic material, such as rubber, as brush 671 removes foreign substances remaining in filter units 65 as it is rotated.
    [0128] That is, if brush 671 has high hardness, there is a possibility that brush 671 will damage filter units 65, and if brush 671 has low hardness, it may be more difficult to remove the remaining foreign substances in the filter units 65.
    [0129] For this purpose, brush 671 includes a plurality of recesses 6711 provided in the longitudinal direction of brush 671.
    [0130] The plurality of recesses 6711 locally reduces the thickness of brush 671, thus allowing the shape of brush 671 to be deformed when brush 671 comes into contact with filter units 65.
    [0131] Therefore, the plurality of recesses 6711 facilitates a change in the direction of brush 671 when the foreign substance removal unit 67 is repeatedly rotated clockwise and counterclockwise (eg, reciprocally rotated).
    [0132] Additionally, instead of the plurality of recesses 6711, a plurality of holes 6713 may be provided, as shown in FIG. 7B.
    [0133] Structures of the foreign substance removal unit 67 shown in FIGs. 8A to 8C differ from the structures of the foreign substance removal unit 67 shown in FIGs. 7A and 7B where holes 6731 are provided at the two opposite ends of brush structure 673 and brush 671 includes inserts 6715 inserted into holes 6731.
    [0134] The foreign substance removal unit 67 is repeatedly rotated clockwise and counterclockwise within the housing. Therefore, if a contact angle between the brush 671 and the filter unit 65 is not changed when the direction of rotation of the foreign substance removal unit 67 is changed, it may be difficult for the foreign substance removal unit 67 to remove the foreign substances remaining in the filter unit 65.
    [0135] This problem can be solved by brush 671, which is rotated in relation to brush structure 673.
    [0136] That is, if brush 671 additionally includes contact parts 6717 extended from insertion parts 6715 and exposed out of holes 6731 through the holes in holes 6731, the above question can be resolved.
    [0137] The 6731 holes may have several molded cross sections, eg, they may have a circular cross section or a rectangular cross section, as shown in FIGs. 8B and 8C. Here, the insert parts 6715 of brush 671 have a shape corresponding to the cross-sectional shape of holes 6731.
    [0138] Additionally, the brush frame 673 may include a pair of support pieces 6733 extended from the two opposite ends of each hole.
    [0139] The support parts 6733 establish a Q2 rotation range of the contact part 6717 of the brush 671, thus preventing the brush 671 from being excessively rotated and thus fail to remove the remaining foreign substances in the filter unit 65.
    [0140] For this purpose, a distance between the support parts 6733 may be greater than the width of the contact part 6717, which will be described later, and an inclined surface 6735 at a designated angle can be provided at the end of each part of support 6733.
    [0141] Brush 671 having the structure described above is reciprocally rotated clockwise and counterclockwise within the angle range predetermined by the motor 7. From now on, the reciprocal rotation of the angle range of brush 671 will be described with reference to FIGs. 9A to 9D.
    [0142] Brush 671 is rotated reciprocally in the housing by motor 7 rotatable clockwise and counterclockwise, thus moving the remaining foreign substances in the filter unit 65 to a storage space 69 located inside the housing and compressing the foreign substances.
    [0143] The reciprocal rotation of the brush 671 serves to move the remaining foreign substances in the filter unit 65 including the first filter and the second filter to one side of the housing in order to reduce the remaining foreign substances in the filter unit 65.
    [0144] The compression of foreign substances in the storage space 69, provided in the wrapper, by brush 671 serves to increase the frequency of operation of the clothing treatment equipment in order to reduce the inconvenience in which a user frequently empties the filter set 6 even if a large amount of foreign substances are stored in the filter set 6.
    [0145] In this case, the reciprocal rotation of the angle range A of brush 671 can be configured to have areas B overlapping a storage space 69.
    [0146] However, although foreign substances are stored in a compressed state within the housing 61 of the filter assembly 6, the foreign substances obstruct a part of the filter unit 65 and thus the filtering capacity of the filter assembly 6 is inevitably reduced .
    [0147] Therefore, a format of the filter unit 65 to reduce the decrease in the filtering capacity of the filter set 6 even if foreign substances are stored in the filter set 6 will be described hereinafter.
    [0148] The filter unit 65 may have an asymmetric circular shape, as shown in FIG. 9A. That is, the filter unit 65 may be formed by connecting at least two circular arcs having different radii of curvature.
    [0149] In this case, a radius R of curvature of a part of the filter unit 65 formed in the direction of stored foreign substances may be greater than a radius r of curvature of a part of the filter unit 65 formed in the direction of the inflow surface. 63, and the brush 671 is rotationally equipped within the circle formed by the connection of the circular arc having the radius r of curvature and a circular arc having radius R of curvature.
    [0150] The circular arc having the radius r of curvature can be provided in the circular arc having the radius R of curvature, as shown in FIG. 9A, and a circular arc having radius r of curvature may be provided under the circular arc having radius R of curvature, which is different from that shown in FIG. 9A.
    [0151] In some implementations, storage space 69 is located within a space provided by the circular arc having radius R of curvature. This causes the storage space 69 to be located within a space having a greater radius of curvature, thereby reducing a drop in the filtering capacity of the filter assembly 6 even though foreign substances are located within the storage space 69.
    [0152] Unlike the above description, the filter unit 65 can be supplied of a type in which a circular arc having the same radius of curvature r as the radius of rotation of brush 671 and a circular arc having a radius of curvature R less than the radius of rotation of the brush 671 in order to reduce the drop in the filter rate of the filter assembly.
    [0153] Additionally, FIG. 9B illustrates the filter unit 65 having a polygonal shape equipped with a plurality of sides.
    [0154] In this case, the filter unit 65 can be configured so that a width w2 of a part of the filter unit 65 formed in areas B in which foreign substances are accumulated is greater than the width wl of a part of the unit of the filter. filter 65 equipped with inflow surface 63.
    [0155] Since brush 671 is rotated reciprocally by the axis of rotation of brush 675, if the width of the filter unit 65 is increased in the direction of the inflow surface 63 to the storage space 69, the drop in the filtering capacity of the filter set 6 may be reduced although foreign substances are stored at the lower end of filter unit 65.
    [0156] FIG. 9C illustrates the filter unit 65 having a rectangular shape. Such a shape of the filter unit 65 is useful if the filter assembly 6 has the structure of FIG. 3.
    [0157] In this case, the axis of rotation of the brush 675 may be provided in the center on one side of the filter unit 65, and a storage space 69 is located on the side of the filter unit 65 equipped with the axis of rotation of the brush 675.
    [0158] If the rotation axis of brush 675 is provided in the upper portion of the filter unit 65, as shown in FIG. 9C, the filter assembly may also include discharge orifices 619 and a suction device connected to discharge orifices 619, as shown in FIG. 3, to discharge foreign substances into storage space 69 out of the housing.
    [0159] FIG. 9D illustrates the filter unit 65 having a semicircular shape. Here, a radius of the semicircular filter unit 65 is equal to or less than a brush length 671.
    [0160] The control of the rotational direction of the motor 7 in order to rotate the brush 671 reciprocally within the predetermined angle range A can be achieved by the method of using a brush position detection sensor 671 and a control unit (not shown) to receive a signal from the sensor and then change the rotational direction of the motor, or a method of using stops and a motor to automatically change a rotational direction if the disturbance rotation of the 671 brush resistance is detected. The last example is described in the following section.
    [0161] Motor 7 may be a synchronous motor that automatically changes the rotational direction of the rotation axis of motor 71 when the disturbance rotation of brush 671 resistance is detected, and stops can contact brush 671 in a way to restrict the rotation of brush 671 if brush 671 is rotated in one direction by the predetermined angle.
    [0162] Therefore, when the 671 brush is rotated in a direction outside the clockwise and counterclockwise direction and comes into contact with the stop, the motor automatically changes the rotational direction of that, thus rotating the brush 671 in the opposite direction .
    [0163] FIGS. 10A and 10B and FIGs. 11A and 11B illustrate stops in accordance with implementations of the present disclosure. The stops are described in more detail below.
    [0164] The stops 616 may be a pair of protrusions provided in the housing 61 and separated from each other by the same angle as the angle of rotation of the brush 671.
    [0165] In this case, the stops 616 may be provided within a filter area of the filter unit 65, as shown in FIG. 10A, or be provided outside the filter area of the filter unit 65, as shown in FIG. 10B.
    [0166] FIGs. 11A and 11B illustrate a stop 6551 provided in the filter unit 65. In this case, a groove for receiving stop 6737 for receiving stop 6551 is provided in the frame of brush 673.
    [0167] That is, the stop 6551 shown in FIG. 11 is projected from the outer circumferential surface of a shaft through hole 655 provided in the filter unit 65 so that the axis of rotation of brush 675 passes through shaft through hole 655, and a receiving groove of stop 6737 is provided. folded into the 673 brush frame.
    [0168] In this case, a width of the receiving groove of the stop 6737 can be configured to make the stop 6551 contact the receiving groove of the stop 6737 when the brush structure 673 is rotated by the predetermined angle.
    [0169] The clothing treatment equipment having the configuration described above filters out foreign substances, such as lint, generated during a drying process of clothing and discharges the remaining foreign substances in the filter unit to the outside of the filter assembly, thus reducing a decrease in drying efficiency.
    [0170] Additionally, the garment treatment equipment compresses foreign substances and then stores the compressed foreign substances in the storage space, thus reducing the frequency of cleaning the filter set.
    [0171] However, clothing treatment equipment in accordance with this disclosure requires a user to periodically remove foreign substances stored in the filter assembly. Therefore, a detection unit to determine whether an amount of foreign substances stored in the filter set exceeds an acceptable amount of foreign substances (eg, a predetermined reference storage quantity) will now be described.
    [0172] The detection unit may be an angle detection unit for detecting a range of rotation angle of brush 671. In this case, cabinet 1 may include a display unit 11 (with reference to FIG. 1) to inform a user that the amount of foreign substances collected exceeds the amount of reference storage based on a signal provided from the detection unit.
    [0173] When the quantity of foreign substances stored in the filter set exceeds a reference storage quantity, brush 671 is rotated reciprocally within an angle range less than the predetermined angle range.
    [0174] Therefore, if the angle detection unit is provided in order to detect whether the 671 brush is rotated within the angle range less than the predetermined angle range in a regular direction or in the reverse direction, the The detection unit can determine the discharge time of foreign substances stored in the filter assembly.
    [0175] The angle detection unit may include at least one contact sensor provided in the same position as the 616 or 6551 stop position, or two contact sensors having an angle range less than the configured reciprocal rotation angle range of brush 671.
    [0176] In an alternative implementation, the filter set may include at least one weight sensor to weigh the amount of foreign substances collected. The weight sensor may trigger an alert to inform a user, using display unit 11, that the amount of foreign matter collected exceeds a reference weight based on the weight of the foreign substance collected detected by the weight sensor. In yet another alternative implementation, the filter set may include at least one infrared (IR) sensor that intercepts an IR beam produced by an IR beam generation unit. If the quantity of foreign substances collected exceeds the reference storage quantity, then the IR sensor will not be able to intercept (eg "detect") the IR beam and will therefore trigger an alert to indicate to a user that the quantity of foreign substances collected exceeds the reference storage quantity.
    [0177] Display unit 11 may be provided as a panel (an LCD panel or an LED panel) to display a message to a user to empty the filter assembly where foreign substances are stored, or to be supplied as a speaker to provide an alarm.
    [0178] FIGS. 12A and 12B illustrate a filter assembly 6 in accordance with another implementation of the present disclosure. The filter assembly 6 in accordance with this implementation is characterized in that the storage space 69 is provided as a collection unit 691 coupled and uncoupled from the housing 61.
    [0179] In this case, positional relationships between the filter assembly 6, the storage space 69 and the discharge duct 41 are shown in FIG. 22 or 23.
    [0180] The filter set 6 in accordance with this implementation additionally includes a communication port 617 provided in the lower portion of the housing 61 for discharging foreign substances to the collection unit 691.
    [0181] The collection unit 691 includes a connection piece 693 connected to the lower portion of the housing 61 and a storage piece 695 attached to connection piece 693 to store foreign substances.
    [0182] Connection piece 693 may be equipped with an opening 6931 communicating with connection hole 617 and with storage part 695.
    [0183] The connection piece 693 may have several structures that cause the take-up unit 691 to be coupled and decoupled from the housing 61, ex. : a pair of male and female holes or a set of clamps and clamp grooves.
    [0184] Therefore, to remove foreign substances stored in the collection unit 691, a user separates the filter assembly 6 from the discharge duct 41, separates the collection unit 691 from the housing 61, and then washes the storage piece 695.
    [0185] The storage part 695 may be formed of various materials in various forms provided that the storage part 695 can store the foreign substances discharged through the communication hole 617.
    [0186] If storage part 695 is provided as a mesh, storage part 695 may function as a third filter.
    [0187] That is, the air introduced in the casing 61 can be supplied to the interior of the duct unit 4 through the storage part 695 of the collection unit 691, as well as the filter unit 65, and thus the storage part in the form of a 695 mesh, you can perform the filter function.
    [0188] As shown in FIG. 13, in the filter set 6 in accordance with this implementation, the rotation area A of the brush 671 can be configured to overlap the storage area provided by the collection unit 691 in order to form overlap areas B.
    [0189] When brush 671 is rotated in one direction (for example, counterclockwise), the remaining foreign substances in the filter unit 65 move to the take-up unit 691 through the communication hole 617.
    [0190] Here, motor 7 rotates the axis of rotation of brush 675 until the free end of brush 671 (eg, one end of brush 671 into which the axis of rotation of brush 675 is not inserted) is received at pickup unit 691, and then causes brush 671 to be rotated clockwise when the free end of brush 671 is received at pickup unit 691.
    [0191] Changing the rotational direction of brush 671 when the free end of brush 671 is received in the take-up unit 691 serves to compress foreign substances stored in storage part 695.
    [0192] Therefore, although the frequency of operation of the laundry equipment is increased and thus a large amount of foreign substances is stored in the storage part 695, the brush 671 compresses the foreign substances and thus the filter set 6 accordingly this disclosure may reduce the volume of foreign substances stored in the 691 collection unit.
    [0193] The configuration and method of rotating the 671 brush reciprocally within the predetermined angle range are described above, and thus a detailed description of these is not repeated.
    [0194] FIG. 14 illustrates a structure of a filter set for automatically disposing of foreign substances stored in a collection unit in accordance with another implementation of the present disclosure. The collection unit 691 in accordance with this implementation includes an introduction hole 6951 that communicates with the outside and a discharge hole 6953.
    [0195] A fluid supply unit 8 for supplying a fluid, such as air or water, is connected to the introduction port 6951, and a discharge hose 697 through which foreign substances in the collection unit 691 together with a fluid are discharged to the outside, connected to the discharge port 6953.
    [0196] Although the introduction port 6951 and the discharge port 6953 provided in the collection unit 691 will now be described, in the case of the filter assembly (with reference to FIG. 2) where a storage space is provided inside the housing, the insertion port and the discharge port can be provided in the filter assembly housing.
    [0197] FIGS. 15A to 15E illustrate cases in which washing water is supplied to the collection unit 691 by means of the fluid supply unit 8. In particular, FIG. 15A illustrates a case in which the introduction port 6951 is connected to a source of water supply supplied to the outside of the garment treatment equipment by means of a supply hose 81.
    [0198] In this case, the recovery unit 691 provided detachably in the communication hole 617 of the housing 61 can be located in the discharge duct 41.
    [0199] Therefore, an orifice communicating with the opening 6931 of the collection unit 691 with a communication orifice 617 of the housing 61 may be provided in the discharge duct 41.
    [0200] Additionally, a nozzle 83 can be provided at the end of the supply hose 81 in order to effectively remove foreign substances in the 691 take-up unit. In addition, the bottom surface of the 691 take-up unit can be tilted towards the hose discharge 697.
    [0201] FIGs. 15B and 15C respectively illustrate structures in which washing water is supplied to the interior of the collection unit using a condensation piece provided in the circulation type treatment equipment.
    [0202] A circulation type clothing treatment equipment of FIG. 15B includes a heating piece 57 and a condensing piece 51 for spraying condensation water, supplied from a water supply source provided on the outside of the garment treatment equipment into the interior of the duct unit 4.
    [0203] Therefore, if the supply hose 81 is supplied in order to supply condensation water, sprayed from the condensation piece 51 and discharged from the duct unit 4, to the collection unit 69, an effect may be achieved in the which the condensation water allows foreign substances inside the collection unit 69 to be discharged outside.
    [0204] FIG. 15C illustrates a circulation-type garment equipment equipped with a heat pump as an air supply unit 5.
    [0205] Heat pump 5 is a heat exchange device in which an evaporator 511, a compressor P, a condenser 513 and an expander E are connected via a cooling circulation channel.
    [0206] Evaporator 511 absorbs heat from the air introduced into duct unit 4 and evaporates a refrigerant, thus removing moisture from the air that comes in contact with evaporator 511. Additionally, condenser 513 discharges latent heat generated from a condensation process of the refrigerant into the duct unit 4, thus heating air that comes in contact with condenser 513. Therefore, if the heat pump is supplied as an air supply unit 5, evaporator 511 serves as a condensing piece and a capacitor 513 serves as a heating part.
    [0207] In this case, since air flowing into the duct unit 4 is condensed through heat exchange with an evaporator 511, the evaporator 511 generates condensation water.
    [0208] Therefore, if a sump 59 for collecting condensation water is provided in the lower portion of the evaporator 511 and a supply hose 81 is provided in order to connect the sump 59 with a 691 collection unit, the washing of the 691 recovery using condensation water is possible.
    [0209] FIG. 15D illustrates a filter assembly 6 in accordance with another implementation of the present disclosure in which a collection unit 691 and a sump 59 are fitted within a basket and a basket serves as a fluid supply unit 8.
    [0210] In this case, the bottom surface of the basket can be tilted so that the condensation water collected in the pit 59 can flow towards the collection unit 691.
    [0211] FIG. 15E illustrates a filter assembly 6 in accordance with another implementation of the present disclosure in which a basket is tilted towards the pit 59. In this case, the fluid supply unit 8 includes a supply hose 81 to supply washing water supplied from an external water supply source for the inside of the basket, and a nozzle 83 is provided on the supply hose 81.
    [0212] FIG. 16 illustrates a filter set 6 in accordance with another implementation of the present disclosure.
    [0213] Filter set 6 in accordance with this implementation is characterized by the fact that foreign substances inside storage space 69 are compressed when brush 671 is rotated in a specific direction and a spiral foreign substance guide 657 is provided in the outer circumferential direction of the filter unit 65 from the center of the filter unit 65.
    [0214] If the brush 671 is not formed in the center of the filter unit 65, the foreign substance guide 657 can be supplied in a spiral in the outer circumferential direction of the filter unit 65 of the rotation axis of the brush 675.
    [0215] In the filter set 6 having the configuration described above, when the brush 671 is rotated, foreign substances remaining in the filter unit 65 are moved to the storage space 69 under the guidance of the foreign substance guide 657. In this case, the foreign substance guide 657 has a spiral structure, the width of which decreases in the direction closest to the outer circumferential surface of the filter unit 65, and thus foreign substances are compressed and stored in an area (eg storage space 69) where the outer circumferential surface of the filter unit 65 and a foreign substance guide 657 come into contact (with reference to FIGS. 17 (a) to 17 (c)).
    [0216] The filter set 6 in accordance with this implementation may also include a brush guide 68 to rotate brush 671 under the guidance of foreign substance guide 657. Brush guide 68 serves to enable brush 671 to pass through storage space 69 during brush rotation 671.
    [0217] The brush guide 68 can be supplied in various formats as long as the brush guide 68 can perform the function described above, and a detailed description of that is not repeated.
    [0218] Although FIG. 16 and FIGS. 17 (a) to 17 (c) illustrate the brush having a curved shape, a brush having a straight shape can be provided.
    [0219] FIG. 18 illustrates a filter set in accordance with another implementation of the present disclosure. The filter assembly in accordance with this implementation includes a brush frame 673 rotationally provided on filter unit 65, a brush 671 provided on brush frame 673, and a pair of protrusions 659 projected from the center of rotation of the brush structure 673 in the outer circumferential direction of the filter unit 65.
    [0220] In this case, a space provided between the protrusion pair 659 becomes a storage space 69.
    [0221] Protrusions 659 are projected from the surface of filter unit 65, and brush 671 has a length to contact the surface of filter unit 65. Therefore, when brush structure 673 is rotated, foreign substances in the filter unit 65 is moved in the direction of protrusions 659 by brush 671, and brush 671 compresses foreign substances as they pass protrusions 659 and then moves compressed foreign substances into storage space 69.
    [0222] Storage space 69 may be sufficiently deep to prevent brush 671 from coming into contact with storage space 69. This depth of storage space 69 is used to allow foreign substances moved to storage space 69 to be separated. of brush 671 and then stored within storage space 69.
    [0223] The filter set in accordance with this implementation may also include a pressure unit 66 (see, for example, FIG. 19) to supply pressure to brush 673 in order to maintain brush 671 contact with the unit filter 65.
    [0224] Pressure unit 66 includes a pressure protrusion 661 designed from brush frame 673 and a groove for receiving protrusion 663 to receive pressure protrusion 661.
    [0225] If the filter assembly has a frame where a first housing part and a second housing part are folded, brush structure 673 can be provided in the first housing part and a protrusion receiving slot 663 can be provided in the second part of the enclosure.
    [0226] The lengths of the brush bristles 671 provided in the brush structure 673 may be the same along the brush structure 673 (eg, having an aerodynamic shape), as shown in FIG. 20A, be irregular, as shown in FIG. 20B, or be gradually increased or decreased as the brush bristles 671 distance from the axis of rotation of the brush 675, as shown in FIG. 20C.
    [0227] When the bristle lengths of brush 671 are regular, brush 671 comes into contact with the surface of filter unit 65 at regular pressure and thus completely removes the remaining foreign substances in filter unit 65, but an amount of Brush wear 671 increases and the motor load increases. Therefore, if brush bristles 671 are of uneven length, a reduction in the amount of brush 671 wear and a reduction in motor load can be expected.
    [0228] Since components, such as driven gear and motor, are located around the axis of rotation of the 675 brush, more foreign substances may be collected at the edge of the filter unit 65 than at the center of the filter unit filter 65. Therefore, if the bristles of brush 671 have lengths that gradually increase or decrease while the bristles of brush 671 move away from the axis of rotation of brush 675, an area where foreign substances are locally concentrated can be effectively cleaned.
    [0229] FIG. 21 illustrates a filter assembly in accordance with another implementation of the present disclosure characterized in that a storage space 69 provided in a housing 61 includes a foreign substance inflow orifice 699 and a collection unit 698.
    [0230] That is, the storage space 69 in accordance with this implementation includes the collection unit 698 located within an internal space formed by the first part of the housing and the second part of the housing and an inflow orifice of foreign substance 699 for guide foreign substances removed from a rotating brush to the 698 take-up unit.
    [0231] As apparent from the description above, the present disclosure provides clothing treatment equipment with a filter set that removes foreign substances from the air discharged from a clothing accommodation space.
    [0232] Additionally, the present disclosure provides a garment treatment equipment with a filter set in which the filter units for removing foreign substances are automatically cleaned.
    [0233] Additionally, the present disclosure provides a clothing treatment equipment with a filter set where foreign substances removed by the filter unit are compressed and then stored.
    [0234] Additionally, the present disclosure provides a clothing treatment equipment in which a storage space for storing foreign substances is automatically washed.
    [0235] It will be apparent to those with experience in the technique that various modifications and variations can be made in the present disclosure without departing from the essence or scope of the implementations. Thus, it is intended that the present disclosure includes the modifications and variations provided provided that they are within the scope of the attached claims and their equivalents.
