Description

TECHNICAL FIELD

[0001] Various embodiments of the disclosure relate to a lint cleaning device and a laundry treating apparatus including the same. BACKGROUND

[0002] A laundry treating apparatus is an apparatus configured to dry laundry by rotating a drum in which laundry articles such as laundry, a towel, a blanket, etc. are accommodated and supplying hot air into the drum. Depending on how moisture absorbed from laundry articles to be dried is treated, the laundry treating apparatus can be classified into two types - a condensing type laundry treating apparatus (or a circulating type laundry treating apparatus) and an exhaust type laundry treating apparatus.

[0003] In the condensing type laundry treating apparatus, moist air (or moisture) can be formed by heat exchange with laundry articles (e.g., laundry, a towel, or shoes) in the drum, and such moist air is circulated within the apparatus without being discharged to the outside. A heat exchanger of the laundry treating apparatus treats the moist air to produce condensate, which is then discharged to the outside of the apparatus. The exhaust type laundry treating apparatus can perform a heat exchange process on laundry articles to be dried in the drum, thereby forming moist air, which is directly discharged from the drum to the outside of the laundry treating apparatus via an exhaust duct.

[0069] The various embodiments shown below Figures 1 to 19d and the principles of the present disclosure illustrated in this patent document are by way of example only and should not be construed as limiting the scope of the present disclosure in any way. It will be understood by those skilled in the art that the principles of the present disclosure can be implemented in any suitably arranged system or device.

[0070] Embodiments of the present disclosure are now described with reference to the accompanying drawings so as to be easily practiced by those of ordinary skill in the art. However, the present disclosure can be implemented in other various forms, and is not limited to the embodiments set forth herein. Throughout the specification and the drawings, like or similar reference numerals can be used to refer to like or similar elements. Also, for the sake of brevity and clarity, well-known functions and constructions are not described in detail herein.

[0071] Figure 1 ​​is a perspective view showing an example laundry treating apparatus according to an embodiment. Figure 2 is a cross-sectional view schematically showing an example laundry treating apparatus according to an embodiment. Figure 3 is a conceptual view schematically showing Figure 2 an example air circulation path of air circulating inside and outside a drum of a laundry treating apparatus and an example refrigerant circulation path of a heat exchanger.

[0072] For convenience of description, Figures 1 to 3 A laundry dryer is shown as an example of the laundry treating apparatus 1, but the present disclosure is not limited thereto.

[0073] Referring to Figures 1 to 3 , the laundry treating apparatus 1 can include a main body 10, a drum 20 (or a laundry containing unit), a door 30, a control panel 40, an air circulation path 50, a driver 60, or a heat exchanger 70.

[0074] According to an example embodiment, the main body 10 can be provided to contain therein components such as the drum 20 or the heat exchanger 70. The main body 10 can have, for example, a hexahedral shape, but the present disclosure is not limited thereto. The main body 10 can include an upper frame 10a, a lower frame 10b, a rear frame 10d, a front frame 10c, a left frame 10e, and a right frame (not shown). An opening can be formed in the front frame 10c, and the door 30 can be provided at a portion corresponding to the opening. Here, at least two of the upper frame 10a, the lower frame 10b, the front frame 10c, the rear frame 10d, the left frame 10e, or the right frame can be integrally formed, or each of them can be separately manufactured and assembled. Further, each of the upper frame 10a, the lower frame 10b, the front frame 10c, the rear frame 10d, the left frame 10e, or the right frame can be press-formed with a sheet iron material or injection-molded with a resin material.

[0075] According to an example embodiment, the door 30 can be rotatable in conjunction with a hinge fixed to the front frame 10c. For example, at least a portion of the door 30 can be formed with a transparent material so that the inside is visible from the outside. The door 30 can be opened or closed to put a drying article (e.g., clothes) into the drum 20 located inside the main body or take out the drying article (e.g., clothes) from the drum 20. For example, the door 30 can be locked by a locking device (not shown) to prevent opening while the laundry treating apparatus 1 is driven (or operated).

[0076] According to an example embodiment, the door 30 can include a door frame 31 or a glass member 32. The glass member 32 can be formed with, for example, a transparent tempered glass material to allow visibility through the inside of the main body 10. The glass member 32 can protrude toward the inside of the drum 20 to prevent a drying article (e.g., laundry) to be inclined toward the door 30 while the laundry treating apparatus 1 is driven.

[0077] According to an example embodiment, the drum 20 can have a cylindrical shape, and the opening 20a can be formed at one side of the drum 20. Specifically, the drum 20 can have a cylindrical shape horizontally disposed in the main body 10, and the opening 20a can be formed at a front portion of the drum 20. The opening can be disposed at a position corresponding to the door 30. A user can put the laundry to be dried into the drum 20 through the opening 20a of the drum 20, or take out the dried laundry from the inside of the drum 20. The drum 20 can be disposed to be rotatable by receiving power from the driver 60.

[0078] According to an embodiment, the drum 20 can include a plurality of lifters 21 disposed inside and spaced apart from each other by a predetermined interval along a circumferential direction. For example, the lifters 21 can lift the laundry to be dried (e.g., clothes) while the drum 20 rotates, such that the laundry to be dried (e.g., clothes) repeatedly rises and falls, thereby uniformly drying a plurality of surfaces of the laundry to be dried (e.g., clothes).

[0079] According to an example embodiment, the control panel 40 can include an input unit 41 or a display unit 42. For example, the input unit 41 can be configured to acquire a user input for controlling the laundry treatment apparatus 1. For example, the input unit 41 can include a power button for turning on / off a power source of the laundry treatment apparatus 1 or an operation button for setting a drying operation of the laundry treatment apparatus 1. The power button or the operation button can be, for example, a tactile switch, a press switch, a slide switch, a jog switch, a micro switch, or a touch switch, but the present disclosure is not limited thereto. Alternatively, the input unit 41 can include an input device in the form of a jog shuttle as shown in FIG. 2B, which can be held and rotated. The display unit 42 can display, for example, a drying setting or drying operation information in response to a user input. The display unit 42 can include, for example, various types of display panels such as a liquid crystal display (LCD), a light emitting diode (LED), an organic light emitting diode (OLED), a quantum dot light emitting diode (QLED), or a micro LED, and can be implemented as a touch screen by providing a touch panel on a front surface thereof, but the present disclosure is not limited to a specific type of display. Figure 1

[0080] According to an example embodiment, the air circulation flow path 50 can include an inlet flow path 51, a connection flow path 52, or a discharge flow path 53. When the laundry treatment apparatus 1 is operated, high-temperature high-humidity air can be introduced into the inlet flow path 51 to dry the laundry to be dried (e.g., laundry) put into the drum 20, and high-temperature low-humidity air can be discharged into the discharge flow path 53. The high-temperature high-humidity air introduced through the inlet flow path 51 can be heated and dehumidified by the heat exchanger 70 when passing through the connection flow path 52 to be converted into high-temperature low-humidity air. Referring to FIG. 1B, the air circulation flow path 50 is shown by a solid line. The air circulation flow path 50 can be formed by the drum 20, the heat exchanger 70, and the duct 80. Figure 3 , the air circulation flow path 50 is shown by a solid line. The air circulation flow path 50 can be formed by the drum 20, the heat exchanger 70, and the duct 80.​Figure 3 The solid line sequentially passes through the blower 64, the evaporator 71, or the condenser 73, is dehumidified, and is heated.

[0081] According to an example embodiment, the inlet flow path 51 can be formed by an inlet duct 11. The inlet duct 11 can be positioned at, for example, a lower front portion of the drum 20. In other words, the inlet duct 11 can be disposed adjacent to a front frame 10c of the main body 10, but is not limited thereto.

[0082] According to an example embodiment, the laundry treating apparatus 1 can include a filter member 12. The filter member 12 can be installed or disposed on the lint cleaning device 90. For example, the filter member 12 can be disposed on an upstream side of the heat exchanger 70 in the air circulation path. Air introduced into the inlet flow path 51 through the inlet 51a inside the drum 20 can include foreign substances (e.g., lint or dust). If the air is introduced into the inlet flow path 51, such foreign substances can be filtered or treated by the filter member 12.

[0083] According to an example embodiment, the connection flow path 52 can be disposed below the drum 20. The air filtered by the filter member 12 can pass through the inlet flow path 51 and enter the connection flow path 52. The air can be heated and dehumidified by the heat exchanger 70 as it passes through the connection flow path 52. The process of heating and dehumidifying the air by the heat exchanger 70 is described below.

[0084] According to an example embodiment, the exhaust flow path 53 can be formed by an exhaust duct 13. The exhaust duct 13 can be positioned, for example, behind the drum 20. In other words, the exhaust duct 13 can be disposed adjacent to a rear frame 10d of the main body 10, but is not limited thereto. The exhaust duct 13 can be connected to, for example, a rear surface of the drum 20. Accordingly, the high-temperature, low-humidity air passing through the exhaust flow path 53 can be exhausted to an exhaust outlet 53a located on the rear surface of the drum 20 to dry the articles (e.g., laundry) to be dried in the drum 20.

[0085] According to an embodiment, the driver 60 can include a driving motor 61, a pulley 62, a driving belt 63, or a blower 64. The driver 60 can form an air flow in the air circulation flow path 50 by, for example, rotating the drum 20 or using the blower 64. The illustrated driver 60 is disposed such that one driving motor 61 rotates the drum 20 and the blower 64 at the same time, but this is merely an example, and multiple driving motors can be provided to rotate the drum 20 and the blower 64 independently.

[0086] According to an example embodiment, the driving motor 61 can be disposed to transmit rotational power to the pulley 62 and the blower 64. The driving motor 61 can be disposed inside the main body 10. The driving motor 61 can be disposed, for example, below the drum 20.

[0087] According to an example embodiment, the driving belt 63 can be connected to the pulley 62 and can be partially disposed to surround the outer circumferential surface of the drum 20. In other words, the driving belt 63 can rotate the drum 20 by transmitting the rotational power of the pulley 62 to the drum 20. The drum 20 can rotate clockwise or counterclockwise according to the driving or operation of the driving motor 61.

[0088] According to an example embodiment, the blower 64 can receive the rotational power from the driving motor 61. The blower 64 can be disposed to internally circulate air by forming an air flow in the air circulation flow path 50. The blower 64 can be disposed, for example, in the connection flow path 52. The blower 64 can be disposed, for example, adjacent to the inlet flow path 51. Alternatively, the blower 64 can be disposed at a portion or region where the inlet flow path 51 and the connection flow path 52 are connected. Accordingly, the air in the drum 20 can be effectively introduced into the inlet flow path 51 by the rotation of the blower 64.

[0089] According to an example embodiment, the heat exchanger 70 can include an evaporator 71, a compressor 72, a condenser 73, or an expansion valve 74. The evaporator 71, the compressor 72, the condenser 73, or the expansion valve 74 can be disposed below the drum 20. A refrigerant is internally circulated in the heat exchanger 70, and a refrigerant circulation path is shown by a dotted line in Figure 3 As shown in Figure 3 As shown in

[0090] According to an example embodiment, the evaporator 71 can be disposed to evaporate the refrigerant that has become a liquid (or is in a liquid state) at a low temperature and low pressure when passing through the expansion valve 74. As the liquid refrigerant evaporates, heat exchange can occur between the evaporator 71 and the gas around it. The air passing through the connection flow path 52 first passes through the evaporator 71, and the evaporator 71 can absorb the latent heat of the air while evaporating the liquid refrigerant. The air that has absorbed the latent heat can cause the moisture contained in the air to condense as the temperature decreases.

[0091] According to an example embodiment, the compressor 72 can be disposed to compress the gaseous refrigerant delivered from the evaporator 71. The compressor 72 can compress the gaseous refrigerant into a high-temperature and high-pressure state. Specifically, the compressor 72 can receive electric power from the outside and compress the gaseous refrigerant at a high temperature and high pressure using a rotational force such as from a motor. Alternatively, the compressor 72 can compress the refrigerant by reciprocating motion of a piston, but the present disclosure is not limited thereto.

[0092] According to an example embodiment, the condenser 73 can condense the high-temperature and high-pressure refrigerant delivered from the compressor 72. The condenser 73 can dissipate heat generated while condensing the refrigerant to the outside of the condenser 73. The gas that has passed through the evaporator 71 in the connection flow path 52 and is in a low-temperature and low-humidity state can become a high-temperature and low-humidity state due to the heat dissipation of the condenser 73 when passing through the condenser 73. In other words, when the air in a high-temperature and high-humidity state passes through the connection flow path 52, the air can be converted into a high-temperature and low-humidity state by the evaporator 71 and the condenser 73, and is discharged into the drum 20 through the discharge flow path 53. The condensed refrigerant can move back to the evaporator 71 and circulate inside the heat exchanger 70.

[0093] According to an example embodiment, the heat exchanger 70 can further include a refrigerant temperature sensor 75. The refrigerant temperature sensor 75 can be disposed, for example, on a path through or flowed by the refrigerant. In particular, the refrigerant temperature sensor 75 can be disposed on a path between the compressor 72 and the condenser 73 to measure the temperature of the refrigerant discharged from the compressor 72, but is not limited thereto.

[0094] According to an example embodiment, the laundry treatment apparatus 1 can further include a heater 80 disposed inside the air circulation flow path 50. The heater 80 can be positioned, for example, on the discharge flow path 53. In particular, the heater 80 can be disposed downstream of the evaporator 71 and the condenser 73. Accordingly, the heater 80 can additionally heat the air passing through the heat exchanger 70. The heater 80 can further heat the air by assisting the condenser 73, thereby more rapidly increasing the temperature of the air supplied to the drum 20.

[0095] According to an example embodiment, the laundry treatment apparatus 1 can include a lint cleaning apparatus 90. The lint cleaning apparatus 90 can be disposed at a lower portion of the laundry treatment apparatus 1. The lint cleaning apparatus 90 can be disposed to be accessible from the outside by opening the lower door 13. The lint cleaning apparatus 90 can be configured to clean and / or store the lint (or foreign matter) filtered or loaded on the surface of the filter member 12. The structure of the lint cleaning apparatus 90 will be described in detail below.

[0096] Figure 4a and Figure 4b are diagrams illustrating example states in which the lint cleaning apparatus is disposed in the laundry treatment apparatus according to an embodiment.

[0097] Figure 4a and Figure 4b The laundry treatment apparatus 1 shown in Figure 1 and Figure 2 can be substantially the same as the laundry treatment apparatus 1 shown in Figure 1 and Figure 2 . Hereinafter, the same reference numerals will be assigned to components substantially the same as or similar to those shown in .

[0098] Referring to Figure 4a and Figure 4b , the lint cleaning device 90 can be provided at a lower portion of the laundry treating apparatus 1. For example, the lint cleaning device 90 can be provided below the drum (e.g., the drum 20 of Figure 2 ). The lint cleaning device 90 can be provided to be invisible from the outside due to the lower door 13. When the lower door 13 is opened, some of the modular components of the lint cleaning device 90 can be separated from the laundry treating apparatus 1 in a sliding manner. The configuration of the lint cleaning device 90, which is modular and detachable from the laundry treating apparatus 1, is described below.

[0099] According to an embodiment, the lint cleaning device 90 can include a housing 91. Components for removing lint loaded on a surface of a filter member (e.g., the filter member 12 of Figure 2 ) can be accommodated in the housing 91.

[0100] According to an embodiment, the lint cleaning device 90 can include a lint chamber 92. The lint chamber 92 can be provided to accommodate lint cleaned by a brush portion (e.g., the brush portion 540 of Figure 5 ). The lint chamber 92 can be provided to be detachable from the housing 91. The lint chamber 92 can slide into or out of the housing 91. A user can open the lower door 13 and slide the lint chamber 92 out to remove the lint accommodated therein.

[0101] Figure 5 is a perspective view illustrating an example lint cleaning device according to an embodiment. Figure 6 is an exploded perspective view illustrating an example lint cleaning device according to an embodiment. Figure 7 is a view illustrating an example upper portion of a lint cleaning device according to an embodiment. Figure 8 is a view illustrating an example lower portion of a lint cleaning device according to an embodiment.

[0102] Figures 5 to 8 The lint cleaning device 500 illustrated in Figure 1 and Figure 2 may be substantially the same as or similar to the lint cleaning device 90 of the laundry treating apparatus 1 illustrated in Figures 5 to 8 . The lint cleaning device 500 illustrated in Figure 1 and Figure 2 may be included in the laundry treating apparatus 1 illustrated in .

[0103] Figures 5 to 8 The lint cleaning device 500 illustrated in Figure 4a and Figure 4b may be provided on a laundry dryer as illustrated in Figures 5 to 8 , but the laundry treating apparatus 1 described in the disclosure is not limited to a laundry dryer. In other words,The lint removal device 500 shown may include or may be installed in any device that includes a heat exchanger and is used to contain clothes to be dried in a specific space and to dry and heat the humid air discharged from the specific space.

[0104] According to an example embodiment, the lint removal device 500 can be modular. The lint removal device 500 can be installed in a garment processing device (e.g., Figure 4a The garment holding unit of the garment handling device 1) (e.g., Figure 2 Below the roller 20), and can be modularly installed so that it can slide in or out. For example, the components of the lint removal device 500, except for the drive 520, can be modularly installed or disposed in the garment handling device 1 for removable installation.

[0105] Reference Figures 5 to 8 The lint removal device 500 may include all or some of the following: housing 510, drive 520, shaft 530, brush section 540, lint chamber 550, chamber door 560, or operating assembly 570. In garment handling devices (e.g., Figure 1 During the drying cycle of the garment handling device 1), when air containing lint passes through a filter element (e.g., Figure 2 When the filter element 12 is in use, the lint removal device 500 can automatically remove the lint accumulated on the surface of the filter element 12. The lint removal device 500 can be attached to the filter element 12 to remove the lint filtered on the surface of the filter element 12. When the wiped (or removed) lint is contained and fills the lint chamber 550, the garment handling device 1 can detect whether the lint chamber is full.

[0106] According to an example embodiment, housing 510 may form the appearance of lint-removing device 500. Housing 510 may form receiving spaces for placing components such as brush portion 540, lint chamber 550, operating assembly 570, and chamber door 560 therein. For example, a first space 512a may be formed in housing 510 in which brush portion 540 rotates to remove lint. For example, a second space 512b may be formed in housing 510 in which operating assembly 570 is received. For example, the first space 512a in which brush portion 540 is received and the second space 512b in which operating assembly 570 is received may be spatially separated (e.g., separated by a partition wall).

[0107] The housing 510 may form a third space 512c to accommodate the fluff chamber 550. The third space 512c may be connected to the first space 512a. The third space 512c may be spatially separable from the second space 512b. The fluff chamber 550 may be removably accommodated in the third space 512c.

[0108] According to an example embodiment, the housing 510 can include an upper housing 511, a main body housing 512, and a lower housing 513. The upper housing 511 is a portion forming an upper surface of the housing 510, and can be detachably coupled to the main body housing 512. An opening 511a can be formed in the upper housing 511. Air can be circulated through the opening 511a of the upper housing 511. For example, air including lint introduced through the inlet flow path 51 of the laundry treating apparatus (e.g., the laundry treating apparatus 1 of FIG. 1) can be introduced inside the lint cleaning apparatus 500 through the opening 511a. The introduced air can pass through the filter member 12 to filter the lint. Although not shown, the upper housing 511 and the main body housing 512 can be integrally formed. Figure 2

[0109] The main body housing 512 can be configured to define a first space 512a, a second space 512b, and a third space 512c. For example, the second space 512b can be positioned and disposed between the main body housing 512 and the lower housing 513.

[0110] According to an embodiment, the housing 510 can include a filter mounting portion 514 and a shaft through-hole 515. The filter mounting portion 514 can be coupled to the main body housing 512. The shaft through-hole 515 can be formed through one surface of the main body housing 512.

[0111] The filter mounting portion 514 can be a portion formed to mount the filter member 12. The filter mounting portion 514 can be disposed in a direction of movement of a tip portion 540a of a brush portion 540 described below. The filter mounting portion 514 can be open to allow air to penetrate (or pass through). The filter member 12 can be mounted or disposed outside or inside the filter mounting portion 514. For example, the filter mounting portion 514 can have an arc-shaped cross-section. The filter mounting portion 514 can be integrally formed with the housing 510, but is not limited thereto, and can be configured as a separate component coupled to the housing 510.

[0112] The shaft through-hole 515 can be a portion through which a shaft 530 to be coupled (or connected) to the brush portion 540 penetrates or is inserted. The shaft through-hole 515 can be formed through a partition wall between, for example, the first space 512a and the second space 512b.

[0113] ​According to an example embodiment, the driver 520 can be provided to rotate the brush part 540 and the chamber door 560. In the present disclosure, an operation structure in which one driver 520 is used to sequentially open and close the brush part 540 and the chamber door 560 can be provided. The brush part 540 and the chamber door 560 can be rotated due to rotation of a motor provided in the driver 520. For example, rotational power of the driver 520 can be directly transmitted to the brush part 540. Here, the direct transmission of the rotational power can mean not only that the driver 520 and the brush part 540 are directly coupled to each other, but also that even if the motors of the driver 520 are indirectly coupled to each other, the rotational power is transmitted such that an angle of rotation of the motor of the driver 520 and an angle of rotation of the brush part 540 are substantially the same.

[0114] According to an example embodiment, the shaft 530 can be configured to connect the driver 520 and the brush part 540. The shaft 530 can be coupled to a rotation shaft of the driver 520, and can be coupled to the brush part 540 through the shaft through-hole 515 of the housing 510. The shaft 530 can be coupled to the brush part 540 by being inserted into a shaft hole of the brush part 540.

[0115] According to an example embodiment, the brush part 540 can be provided to rotate between a first position and a second position. The brush part 540 can be configured to clean (e.g., remove or clean) lint attached to the filter member 12 by rotating about a rotation axis. The brush part 540 can be configured such that the tip portion 540a rotates along an inner circumferential surface of the filter member 12. When the brush part 540 rotates, the tip portion 540a of the brush part 540 can be adjacent to the inner circumferential surface of the filter member 12 to clean the lint attached to the filter member 12. Here, the rotation axis of the brush part 540 can be the same axis as the rotation axis of the shaft 530. Here, the first position can refer to a position before the brush part 540 starts to clean the lint. Here, the second position can refer to a position in which the brush part 540 is rotated from the first position to complete cleaning of the lint attached to the filter member 12. The second position can be a position relatively closer to the chamber door 560 than the first position. The second position can be a position relatively closer to the lint chamber 550 than the first position.

[0116] The brush portion 540 can rotate in a reciprocating manner between the first position and the second position. For example, when the motor of the driver 520 is driven in a first rotation direction (e.g., a forward direction or a clockwise direction), the brush portion 540 can rotate in a direction from the first position to the second position. For example, when the motor of the driver 520 is driven in the first rotation direction, the brush portion 540 can also rotate in the first rotation direction. The brush portion 540 can move from the first position to the second position to clean lint on the filter member 12, and when reaching the second position, deliver the lint to the lint chamber 550. For example, when the motor of the driver 520 is driven in a second rotation direction (e.g., a reverse direction or a counterclockwise direction) opposite the first rotation direction, the brush portion 540 can rotate from the second position toward the first position. For example, when the motor of the driver 520 is driven in the second rotation direction, the brush portion 540 can also rotate in the second rotation direction. However, the present disclosure is not limited thereto, and the rotation direction of the motor of the driver 520 and the rotation direction of the brush portion 540 can be opposite to the directions shown. The brush portion 540 can be referred to as a "wiper", a "scraper", or a "blade".

[0117] According to an example embodiment, the brush portion 540 can include an elastic body 541 formed of an elastic material or a rubber material. The elastic body 541 can be disposed on a tip portion 540a of the brush portion 540. The elastic body 541 can be a portion positioned adjacent to an inner circumferential surface of the filter member 12 when the brush portion 540 rotates. The tip portion 540a of the brush portion 540 can be formed with the elastic body 541 to prevent the filter member 12 from being damaged when the brush portion 540 rotates.

[0118] According to an example embodiment, the brush portion 540 can include a shaft hole. The shaft 530 can be inserted into the shaft hole to form a rotation axis. The brush portion 540 can rotate between the first position and the second position using the shaft 530 as a rotation axis.

[0119] According to an example embodiment, the lint chamber 550 can be disposed to accommodate lint removed by the brush portion 540. Lint cleaned by rotation of the brush portion 540 can be transported to the lint chamber 550.

[0120] According to an example embodiment, the lint chamber 550 can include a lint inlet 550a. Lint cleaned by rotation of the brush portion 540 can be accommodated in the lint chamber 550 through the lint inlet 550a. When the lint chamber 550 is installed or disposed in the housing 510, the lint inlet 550a can be located between the first space 512a and the third space 512c of the housing 510.

[0121] The lint chamber 550 can be accommodated in the third space 512c of the housing 510. The lint chamber 550 can slide into or out of the housing 510. When the lint chamber 550 is full of lint, the lint chamber 550 can be simply detached to remove the lint.

[0122] According to an example embodiment, a chamber door 560 can be provided to open or close the lint chamber 550. The chamber door 560 can be installed or provided in the housing 510. The chamber door 560 can be provided to open or close a portion of the housing 510 connecting between the first space 512a and the third space 512c. When the chamber door 560 is opened, the chamber door 560 can be opened by moving toward the brush part 540. For example, when the chamber door 560 is opened, the chamber door 560 can be opened by moving toward the first space 512a. The chamber door 560 can open or close the lint chamber 550 by receiving power from the driver 520 through the operation assembly 570 to be described below. The chamber door 560 can be referred to as an opening and closing plate. The chamber door 560 can separate a space in which the brush part 540 cleans lint from a space in the lint chamber 550, thereby preventing the lint in the lint chamber 550 from flowing back into the first space 512a in which the brush part 540 is accommodated and contaminating the inside.

[0123] According to an example embodiment, the chamber door 560 can include a rotation shaft 561. The rotation shaft 561 of the chamber door 560 can be fixed by the housing 510 for other movements other than rotation. For example, the rotation shaft of the chamber door 560 can be rotatably coupled to the upper housing 511 and the main body housing 512.

[0124] According to an example embodiment, the operation assembly 570 can be configured to move the chamber door 560 in response to the operation of the driver. The operation assembly 570 can be accommodated in the second space 512b of the housing 510. The operation assembly 570 can be configured such that the moving direction of the chamber door 560 varies according to the rotation direction of the motor of the driver 520. For example, when the motor of the driver 520 rotates in a first rotation direction, the chamber door 560 can open the lint chamber 550. For example, when the motor of the driver 520 rotates in a second rotation direction, the chamber door 560 can close the lint chamber 550.

[0125] According to an example embodiment, the operation assembly 570 can include a cam 571 coupled to the driver 520, a lever 572 configured to rotate in response to the rotation of the cam 571, and a latch 573 configured to rotate in response to the rotation of the lever 572. Each of the cam 571, the lever 572, and the latch 573 can be accommodated in the second space 512b of the housing 510.

[0126] The cam 571 can be rotatably coupled to the driver 520. The cam 571 can be coupled to a rotation shaft of, for example, the motor of the driver 520, and can rotate according to the operation of the motor. The cam 571 can be provided between the shaft 530 and the driver 520.

[0127] According to an example embodiment, the cam 571 can include a first pressing protrusion 5711, a second pressing protrusion 5712 spaced apart from the first pressing protrusion 5711 in a circumferential direction, and a recess 5713 formed between the first pressing protrusion 5711 and the second pressing protrusion 5712. The first pressing protrusion 5711 can rotate the lever 572 by the pressing of the lever 572. The second pressing protrusion 5712 can rotate the lever 572 by the pressing of the lever 572.

[0128] The first pressing protrusion 5711 and the second pressing protrusion 5712 can have substantially the same radius, but are not limited thereto. The first pressing protrusion 5711 and the second pressing protrusion 5712 can protrude to be spaced apart from the rotation axis by substantially the same distance. The first pressing protrusion 5711 can protrude while maintaining a constant (or same) radius along the circumferential direction, but is not limited thereto. The second pressing protrusion 5712 can protrude while maintaining a constant (or same) radius along the circumferential direction, but is not limited thereto.

[0129] As illustrated, the circumferential length of the first pressing protrusion 5711 can be shorter than the circumferential length of the second pressing protrusion 5712. However, the disclosure is not limited thereto, and unlike what is illustrated, the circumferential length of the first pressing protrusion 5711 can be equal to or greater than the circumferential length of the second pressing protrusion 5712.

[0130] According to an example embodiment, the recess 5713 can be formed between the first pressing protrusion 5711 and the second pressing protrusion 5712. The radius of the recess 5713 can be smaller than the radius of the first pressing protrusion 5711 or the radius of the second pressing protrusion 5712.

[0131] The lever 572 can include a lever protrusion 5721 formed to protrude radially outward. The lever protrusion 5721 can be a portion pressed by the first pressing protrusion 5711 or the second pressing protrusion 5712 of the cam 571. If the lever protrusion 5721 is pressed by the first pressing protrusion 5711 or the second pressing protrusion 5712 of the cam 571, the lever 572 can rotate. When the lever protrusion 5721 is positioned in the recess 5713 of the cam 571, the lever 572 can not be pressed by the cam 571.

[0132] If the lever 572 is pressed by the pressing protrusion 5711 or 5712 of the cam 571 and rotates in one direction, the latch 573 combined to the lever 572 can rotate in response thereto.

[0133] The latch 573 can be configured to rotate in response to the rotation of the lever 572. The latch 573 can be configured to open or close the chamber door 560. The chamber door 560 can rotate together according to the rotation of the latch 573.

[0134] The operation assembly 570 can further include a first spring 574 disposed between the housing 510 and the lever 572. The elastic force of the first spring 574 can apply a force to the lever 572 in a direction in which the chamber door 560 is closed, through rotation of the lever 572.

[0135] The operation assembly 570 can further include a second spring 575 disposed between the housing 510 and the latch 573. The elastic force of the second spring 575 can apply a force to the latch 573 in a direction in which the chamber door 560 is opened.

[0136] According to an example embodiment, the elastic modulus of the first spring 574 can be less than the elastic modulus of the second spring 575, but is not limited thereto.

[0137] Detailed operation methods and processes of the operation assembly 570 are described below.

[0138] According to an example embodiment, the lint cleaning device 500 can include a filter member 12. The filter member 12 can be mounted or disposed on the filter mounting portion 514 of the housing 510. The filter member 12 can have a curved shape. The filter member 12 can have, for example, a cylindrical shape in which some of the side surfaces are open. The filter member 12 can have, for example, an arc shape. However, the present disclosure is not limited thereto, and the filter member 12 can be omitted from the lint cleaning device 500 and can be separately provided and mounted on the filter mounting portion 514.

[0139] According to an example embodiment, the laundry treatment apparatus (for example, the laundry treatment apparatus 1 of Figure 1 ) can further include a sensor (not shown) configured to detect whether the lint chamber is full of lint.

[0140] For example, the sensor can be a current sensor that detects a current flowing through a motor of the driver 520. When the lint chamber 550 is full of lint, a greater force can be required to close the chamber door 560 due to the reaction force of the lint. When a greater force is required, a greater load can be generated on the motor. The laundry treatment apparatus 1 can estimate the load of the motor of the driver 520 based on a current value sensed by the current sensor, and if the load of the motor exceeds a set value, the laundry treatment apparatus 1 can determine that the lint chamber 550 is filled.

[0141] For example, the sensor can be a reed switch. If a reed switch is used as the sensor, a magnetic force forming device can be provided in a portion of the chamber door 560. The reed switch can be coupled to the housing 510 to detect the magnetic force forming device in a state in which the chamber door 560 is closed. If the reed switch detects the magnetic force forming device, the laundry treatment apparatus 1 can determine that the chamber door 560 is closed. When the lint chamber 550 is filled with lint, the chamber door 560 can not be completely closed due to the pressure of the lint. In this case, since the magnetic force forming device is not detected by the reed switch, the laundry treatment apparatus 1 can determine that the lint chamber 550 is filled with lint. The magnetic force forming device can include, for example, a common magnet or an electromagnet, but is not limited thereto. The reed switch can detect the magnetic force forming device.

[0142] Figures 9a to 9e FIG. 1 is a diagram illustrating an example operating assembly according to an embodiment.

[0143] Figures 9a to 9e The operating assembly 570 shown in FIG. 1 can be substantially the same as or similar to the operating assembly 570 shown in FIG. 1. Figures 5 to 8 Among the components of the operating assembly 570 shown in FIG. 1, the same reference numerals are assigned to components that are substantially the same as or similar to the components shown in FIG. 1. Figures 9a to 9e Among the components of the operating assembly 570 shown in FIG. 1, the same reference numerals are assigned to components that are substantially the same as or similar to the components shown in FIG. 1. Figures 5 to 8 Among the components of the operating assembly 570 shown in FIG. 1, the same reference numerals are assigned to components that are substantially the same as or similar to the components shown in FIG. 1.

[0144] Referring to FIG. 1, Figures 9a to 9e The lever 572 can be rotated in a first state or a second state according to a rotation direction of the cam 571. The first rotation direction of the cam 571 can refer to a direction in which the motor of the driver 520 rotates the brush portion (e.g., the brush portion 540 of FIG. 1) from a first position toward a second position. The second rotation direction of the cam 571 can refer to a direction in which the motor of the driver 520 rotates the brush portion 540 from the second position toward the first position. Figure 6

[0145] Figure 9a An example state of the operating assembly 570 when the lever 572 is in the first state is shown. Referring to FIG. 1, Figure 9a The lever 572 can be pressed and fixed by the first pressing protrusion 5711 of the cam 571. The lever protrusion of the lever 572 can be pressed by the first pressing protrusion 5711 of the cam 571. In this case, the lever 572 can be maintained in the first state by the pressing of the cam 571. Here, the first state can refer to a state in which the lever 572 fixes the latch 573 to a specific position to close the chamber door (e.g., the chamber door 560 of FIG. 1). Figure 6 ​In a state in which the lever 572 is fixed to the first state, the latch 573 can be fixed to a certain position such that the latch 573 closes the chamber door 560. The second spring 575 connected to the latch 573 can apply an elastic force to the latch 573 in a direction opposite to a direction in which the lever 572 presses the latch 573 in the first state. Although the second spring 575 applies a force in a direction in which the chamber door 560 is opened, the latch 573 can be fixed in a certain position by the lever 572 to close the chamber door 560.

[0146] Referring to Figure 9b , the cam 571 can be rotated in a first rotation direction. For example, the first rotation direction can refer to a clockwise direction with reference to the drawings. When the cam 571 is rotated in the first rotation direction, the lever protrusion 5721 of the lever 572 can be positioned in the recess 5713 of the cam 571. At any time when the cam 571 is rotated in the first rotation direction, the lever protrusion 5721 of the lever 572 is positioned in the recess 5713 of the cam 571, so that a force applied to the lever 572 by the cam 571 can be removed. In this case, the lever 572 can be rotated in a second rotation direction opposite to the first rotation direction by a predetermined angle to be positioned in a neutral state. Here, the second rotation direction can refer to a counterclockwise direction in the drawings. Here, the neutral state can refer to any one state between the first state and the second state of the lever 572.

[0147] Referring to Figure 9c , the cam 571 can be further rotated in the first rotation direction in a state in which the lever 572 is rotated in the second rotation direction. Figure 9b When the cam 571 is further rotated in the first rotation direction from the state illustrated in FIG. 6B, the lever 572 can be pressed by the second pressing protrusion 5712 of the cam 571. When the lever protrusion 5721 of the lever 572 is pressed by the second pressing protrusion 5712 of the cam 571, the lever 572 can be rotated from the neutral state to a third state. When the lever protrusion 5721 of the lever 572 is pressed by the second pressing protrusion 5712 of the cam 571, the lever 572 can be rotated in the second rotation direction by a predetermined angle. Here, the third state can refer to a state of the lever 572 for fixing the latch 573 to a certain position to open the chamber door (for example, the chamber door 560 of the cooking apparatus 100). Figure 9b Figure 6 When the cam 571 is further rotated in the first rotation direction from the state illustrated in FIG. 6B, the lever 572 can be pressed by the second pressing protrusion 5712 of the cam 571. When the lever protrusion 5721 of the lever 572 is pressed by the second pressing protrusion 5712 of the cam 571, the lever 572 can be rotated from the neutral state to a third state. When the lever protrusion 5721 of the lever 572 is pressed by the second pressing protrusion 5712 of the cam 571, the lever 572 can be rotated in the second rotation direction by a predetermined angle. Here, the third state can refer to a state of the lever 572 for fixing the latch 573 to a certain position to open the chamber door (for example, the chamber door 560 of the cooking apparatus 100).

[0148] Referring to Figure 9d , the cam 571 can be further rotated in the first rotation direction in a state in which the lever 572 is rotated in the second rotation direction. Figure 9c Figure 9d ​​The state shown can be the state when the brush part 540 reaches the second position. The rod protrusion of the rod 572 can pass through the second pressing protrusion 5712 of the cam 571, so that the rod 572 can be unpressed by the cam 571. In this case, the rod 572 can rotate from the second state to the neutral state due to the first spring 574.

[0149] Reference Figure 9e Cam 571 can Figure 9e In the state of rotation in the second rotation direction, the rod 572 rotates. If the cam 571 rotates in the second direction, the rod protrusion 5721 of the rod 572 can be pressed by the second pressing protrusion 5712 of the cam 571. When the cam 571 rotates in the second rotation direction and the rod 572 is pressed, the rod 572 can rotate in the first rotation direction. Due to the pressing of the second pressing protrusion 5712 of the cam 571, the rod 572 can rotate from the neutral state to the first state. In response to the rod 572 rotating to the first state, the chamber door 560 can be closed by rotating the latch 573. When in Figure 9e When the operating assembly is further rotated in the second rotation direction under the given state, it can have Figure 9a The state.

[0150] Figures 10a to 10d This is a diagram illustrating an example operation of the lint removal device according to an embodiment.

[0151] Figures 10a to 10d The lint removal device 500 shown can be used with Figures 5 to 8 The lint removal device 500 shown is essentially the same as or similar to the one described. Figures 10a to 10d Among the components of the operating assembly 570 shown, the same reference numerals are assigned to... Figures 5 to 8 The components shown are essentially the same or similar.

[0152] Figures 10a to 10d The process of organically operating the brush section 540 and the chamber door 560 in the lint cleaning device 500 by operating the driver 520 is shown. Figures 10a to 10d The description of the operation process of the lint removal device 500 and the operation process of the operation assembly 570 will be provided by [the relevant authority / organization]. Figures 9a to 9e The description is replaced by [the description].

[0153] Figure 10a An example state is shown when the brush section 540 is in the first position. When the brush section 540 is in the first position, the chamber door 560 can be closed, separating the space between the first space 512a and the fluff chamber 550. Figure 10a This can be a state where the lint removal device 500 has not yet removed the lint adhering to the filter element 12. When the brush section 540 is in the first state, the operating assembly 570 can remain in place. Figure 9a The state shown in the image.

[0154] Figure 10b The illustration shows an example initial operation of the lint cleaning device 500 configured to rotate the brush portion 540 to clean lint adhering to the filter member 12. The actuator (e.g., Figure 6 The motor of the driver 520 is operable to rotate the brush section 540 and the cam 571. When the motor of the driver 520 rotates in a first rotation direction, the brush section 540 and the cam 571 can rotate in the first rotation direction. When the brush section 540 rotates in the first rotation direction, the lint attached to the filter member 12 can be swept or removed. Here, the first rotation direction may refer to the clockwise direction in the figures. The chamber door 560 can be opened in advance before the brush section 540 reaches the second position. For example, as Figure 9b As shown, the chamber door 560 is opened before the brush portion 540 reaches the second position because the lever 572 is pressed by the second pressing protrusion 5712 of the cam 571. The chamber door 560 can be opened by a latch 573 that rotates in response to the rotation of the cam 571. (See reference...) Figure 9b and Figure 9c Detailed description Figure 10b The mechanism of the operating assembly 570 in the state shown.

[0155] Figure 10c An example state of the brush portion 540 reaching the second position is shown. As the brush portion 540 moves from the first position to the second position, lint adhering to the surface of the filter member 12 can be cleaned. Lint is cleaned or removed by the rotation of the brush portion 540, and the chamber door 560 remains open when the brush portion 540 reaches the second position. The lint cleaned by the brush portion 540 can reside in the space between the open chamber door 560 and the lint chamber 550. (Refer to...) Figure 9d Detailed description Figure 10c The mechanism of the operating assembly 570 in the state shown.

[0156] Figure 10d An example operation is shown whereby the lint-removing device 500 rotates the brush section 540 from a second position to a first position after cleaning. The motor of the driver 520 is operable to rotate the brush section 540 and the cam 571. When the motor of the driver 520 rotates in a second rotation direction opposite to the first rotation direction, the brush section 540 and the cam 571 can rotate in the second rotation direction. Here, the second rotation direction may refer to the counterclockwise direction shown in the figures. The chamber door 560 can be closed before the brush section 540 reaches the first position. For example, as... Figure 9eAs shown in FIG. 11, since the lever 572 is pressed by the second pressing protrusion 5712 of the cam 571 to close the chamber door 560, the chamber door 560 can be closed before the brush part 540 reaches the first position. For example, when the brush part 540 starts to rotate in the second rotational direction at the second position, the chamber door 560 can close the lint chamber 550. For example, when the brush part 540 is still located near the second position, the chamber door 560 can close the lint chamber 550. By spatially separating the space in which the brush part 540 moves from the lint chamber 550, it is possible to prevent the lint contained in the lint chamber 550 from being discharged back to the first space 512a. The chamber door 560 can be opened by the latch 573 that rotates in response to the rotation of the cam 571. Referring to Figure 9e The operation of the mechanism of the assembly 570 in the state shown in FIG. 11 is described in detail. Figure 10d The operation of the mechanism of the assembly 570 in the state shown in FIG. 11 is described in detail.

[0157] According to an example embodiment, the lint cleaning device 500 can include the assembly 570 as described above, and can organically control the operations of the brush part 540 and the chamber door 560 using one driver 520 (or actuator). By minimizing the number of drivers 520, the lint cleaning device 500 can minimize the volume occupied by the lint cleaning device 500 in the limited internal space of the laundry treating apparatus (for example, the laundry treating apparatus 1 of Figure 1 FIG. 1), and reduce manufacturing costs.

[0158] Figure 11 is a perspective view showing an example lint cleaning device according to an embodiment.

[0159] Figure 11 The lint cleaning device 1100 shown in FIG. 11 can be substantially the same as or similar to the lint cleaning device 90 of the laundry treating apparatus 1 shown in Figure 1 and Figure 2 Figure 11 The lint cleaning device 1100 shown in FIG. 11 can include the lint cleaning device 90 of the laundry treating apparatus 1 shown in Figure 1 and Figure 2

[0160] Figure 11 The lint cleaning device 1100 shown in FIG. 11 can be provided in the laundry dryer as shown in Figure 4a and Figure 4b Figure 11 The lint cleaning device 1100 shown in FIG. 11 can include or can be provided in any device including a heat exchanger and for accommodating laundry to be dried in a specific space and drying and heating moist air discharged from the specific space.

[0161] ​​​According to an example embodiment, the lint removal device 1100 can be modular. The lint removal device 1100 can be installed in a garment processing device (e.g., Figure 4a The garment holding unit of the garment handling device 1) (e.g., Figure 2 Below the roller 20), and can be modularly installed so that it can slide in or out. For example, components of the lint removal device 1100, except for the drive 1120, can be modularly installed or disposed in the garment handling device 1 for removable installation.

[0162] Reference Figure 11 The lint removal device 1100 may include all or some of the housing 1110, drive 1120, shaft 1130, or brush section 1140. In garment handling devices (e.g., Figure 1 During the drying cycle of the garment handling device 1), when air containing lint passes through a filter element (e.g., Figure 2 When the filter element 12 is in use, the lint removal device 1100 can automatically remove the lint accumulated on the surface of the filter element 12. The lint removal device 1100 can be attached to the filter element 12 to clean (e.g., remove) the lint filtered onto the surface of the filter element 12.

[0163] According to an example embodiment, housing 1110 may form the appearance of lint removal device 1100. Housing 1110 may form receiving space for placing components such as brush portion 1140 therein. For example, in housing 1110, space 1110a may be formed in which brush portion 1140 rotates to remove lint.

[0164] According to an example embodiment, housing 1110 may include filter mounting portion 1111 or shaft through hole (e.g., Figure 14 (1112) shaft through hole.

[0165] The filter mounting portion 1111 may be a portion configured to mount the filter member 12. The filter mounting portion 1111 may be arranged along the direction of movement of the tip portion 1140a of the brush portion 1140, as described below. The filter mounting portion 1111 may be open to allow air to pass through (e.g., flow through or enter). The filter member 12 may be mounted or disposed outside or inside the filter mounting portion 1111. For example, the filter mounting portion 1111 may have an arcuate cross-section. The filter mounting portion 1111 may be integrally formed with, but is not limited to, the housing 1110, and may be configured as a separate component integrated into the housing 1110.

[0166] The shaft through-hole 1112 can be a portion through which the shaft 1130 to be coupled to the brush portion 1140 passes (e.g., flows through or enters). The shaft through-hole 1112 can be formed to penetrate, for example, the wall surface 1110b of the housing 1110.

[0167] According to an example embodiment, the housing 1110 may include a guide rail 1150. The guide rail 1150 may be formed on a wall surface 1110b of the housing 1110. The guide rail 1150 may be formed, for example, in the form of a groove cut out in the wall surface 1110b of the housing 1110. The guide rail 1150 may be formed within a range of motion (described below) of the brush portion 1140 moving between a first position and a second position. The guide rail 1150 may be configured such that a guide protrusion 1141 of the brush portion 1140, described below, is inserted into the guide rail 1150 to guide the movement path of the guide protrusion 1141.

[0168] According to an example embodiment, the guide rail 1150 may include a first path 1151 and a second path 1152. The first path 1151 may be, for example, a path for guiding the rotation of the brush portion 1140 when it rotates in a first rotational direction at a first position (described below). The second path 1152 may be, for example, a path for guiding the rotation of the brush portion 1140 when it rotates in a second rotational direction at a second position (described below). Each of the first path 1151 and the second path 1152 may be formed in an arc shape. The brush portion 1140 may rotate along either the first path 1151 or the second path 1152.

[0169] According to an example embodiment, the first path 1151 may be positioned radially outward compared to the second path 1152. The radius of the first path 1151 may be larger than the radius of the second path 1152.

[0170] According to an example embodiment, the first path 1151 and the second path 1152 may be connected to each other. The guide protrusion 1141 of the brush portion 1140, described below, can move between the first path 1151 and the second path 1152 via a connecting portion. For example, one end 1151a of the first path 1151 may be connected to one end 1152a of the second path 1152. For example, the other end 1151b of the first path 1151 may be connected to the other end 1152b of the second path 1152.

[0171] According to an example embodiment, the driver 1120 may be configured to rotate the brush portion 1140. In this disclosure, the brush portion 1140 may rotate due to the rotation of a motor included in the driver 1120. For example, the rotational power of the driver 1120 may be directly transmitted to the brush portion 1140. Here, direct transmission of rotational power may mean not only that the driver 1120 and the brush portion 1140 are directly coupled to each other, but also that even if the motor of the driver 1120 and the brush portion 1140 are indirectly coupled to each other, the rotational power is transmitted such that the angle of rotation of the motor of the driver 1120 and the angle of rotation of the brush portion 1140 are substantially the same.

[0172] According to an example embodiment, shaft 1130 may be configured to connect driver 1120 and brush portion 1140. Shaft 1130 may be coupled to the rotating shaft of driver 1120 and may be coupled to brush portion 1140 through shaft through hole 1112 of housing 1110. Shaft 1130 may be coupled to brush portion 1140 by insertion into shaft hole 1142 of brush portion 1140, which will be described below.

[0173] According to an example embodiment, the brush portion 1140 may be configured to rotate between a first position and a second position. The brush portion 1140 may be configured to sweep (e.g., remove or clean) lint adhering to the filter member 12 by rotating about a rotation axis. The brush portion 1140 may be configured such that a tip portion 1140a rotates along the inner circumferential surface of the filter member 12. As the brush portion 1140 rotates, the tip portion 1140a of the brush portion 1140 may be positioned adjacent to the inner circumferential surface of the filter member 12 to clean the lint adhering to the filter member 12. Here, the rotation axis of the brush portion 1140 may be the same axis as the rotation axis of the shaft 1130. Here, the first position may refer to the position before the brush portion 1140 begins cleaning the lint. Here, the second position may refer to the position where the brush portion 1140 has rotated from the first position to complete cleaning the lint adhering to the filter member 12.

[0174] The brush portion 1140 can rotate reciprocally between a first position and a second position. When the motor of the driver 1120 rotates in a first rotational direction (e.g., forward or clockwise), the brush portion 1140 can rotate in a direction from the first position toward the second position. When the brush portion 1140 rotates from the first position to the second position, the tip portion 1140a can be positioned adjacent to the filter element 12. For example, when the motor of the driver 1120 rotates in the first rotational direction, the brush portion 1140 can also rotate in the first rotational direction. The brush portion 1140 can move from the first position to the second position to clean lint from the filter element 12.

[0175] If the motor of the driver 1120 rotates in a second rotation direction opposite to the first rotation direction (e.g., in the opposite or counterclockwise direction), the brush portion 1140 can rotate from the second position toward the first position. For example, when the motor of the driver 1120 rotates in the second rotation direction, the brush portion 1140 can also rotate in the second rotation direction. However, this disclosure is not limited thereto, and the rotation direction of the motor of the driver 1120 and the rotation direction of the brush portion 1140 may be opposite to the directions shown. The brush portion 1140 may be referred to as a "wiper," "scraper," or "blade."

[0176] According to an example embodiment, the brush portion 1140 may include an elastomer 1143 formed of an elastic material or rubber material. The elastomer 1143 may be disposed on the tip portion 1140a of the brush portion 1140. The elastomer 1143 may be a portion positioned adjacent to the inner peripheral surface of the filter member 12 when the brush portion 1140 rotates. The tip portion 1140a of the brush portion 1140 may be formed using the elastomer 1143, thereby preventing damage to the filter member 12 when the brush portion 1140 rotates.

[0177] Figure 12 yes Figure 11 An exploded perspective view of the brush and shaft shown. Figure 13 It is shown Figure 11 The diagram shows the brush section and the shaft.

[0178] Figure 12 and Figure 13 The brush portion 1140 and shaft 1130 shown are compatible with Figure 11 The brush portion 1140 and the shaft 1130 shown are substantially the same or similar. Figure 12 and Figure 13 The brush portion 1140 and shaft 1130 shown may be included in Figure 11 The lint removal device 1100 shown is used in this device.

[0179] Reference Figure 12 and Figure 13 The brush portion 1140 may include a guide protrusion 1141 inserted into a side surface of the brush portion 1140, at least partially protruding from it. At least a portion of the guide protrusion 1141 may be inserted into a recess 1144 formed in the side surface of the brush portion 1140. When the brush portion 1140 rotates, the guide protrusion 1141 may move along the housing (e.g., Figure 11 The guide rail of the housing 1110 (e.g., Figure 11 The path movement formed by the guide rail 1150.

[0180] According to an example embodiment, when the brush portion 1140 rotates from the second position to the first position, the tip portion 1140a may be configured to interact with the filter member (e.g., Figure 2 The brush portion 1140 is spaced apart from the filter element 12. For example, when the brush portion 1140 rotates from the second position to the first position, the guide protrusion 1141 can move to the second path 1152, the oscillation radius of the second path 1152 being smaller than the oscillation radius of the first path 1151. Therefore, the brush portion 1140 can rotate while being spaced apart from the filter element 12.

[0181] According to an example embodiment, brush portion 1140 may include shaft hole 1142. Shaft 1130 may be inserted into shaft hole 1142 to form a rotation axis. Brush portion 1140 may use shaft 1130 as rotation axis to rotate between a first position and a second position.

[0182] According to an example embodiment, the shaft hole 1142 may be formed such that the shaft 1130 can move relative to it. The shaft 1130 may be inserted to move within the shaft hole 1142. The shaft hole 1142 may be configured such that the shaft 1130 can move in one direction within it. For example, the shaft hole 1142 may be configured such that the shaft 1130 can move relative to the radial direction of the arcuate filter member 12. The brush portion 1140 can move in one direction while the shaft 1130 is fixed. From a relative viewpoint with respect to the brush portion 1140, the shaft 1130 can move in one direction within the shaft hole 1142.

[0183] According to an example embodiment, if the shaft 1130 moves relative to the shaft hole 1142, the axis of rotation or radius of rotation of the brush portion 1140 can be changed. According to an embodiment, the lint removal device 1100 can be configured such that the axis of rotation or radius of rotation of the brush portion 1140 varies depending on the relative position of the shaft 1130 with respect to the shaft hole 1142. The shaft 1130 can be fixedly disposed, and the brush portion 1140 can be configured to move due to additional space provided in the shaft hole 1142. From a relative perspective, the shaft 1130 can move relative to the brush portion 1140. In the shaft hole 1142, when the shaft 1130 is positioned relative to the tip portion 1140a of the brush portion 1140, the oscillation radius of the brush portion 1140 can be reduced. In the shaft hole 1142, when the shaft 1130 is positioned relative to the tip portion 1140a of the brush portion 1140, the oscillation radius of the brush portion 1140 can be increased.

[0184] According to the example embodiment, when the brush part 1140 rotates from the first position to the second position, the rotation radius of the brush part 1140 may be greater than the rotation radius of the brush part 1140 when it rotates from the second position to the first position. When the brush part 1140 rotates from the first position to the second position, the guide protrusion 1141 of the brush part 1140 moves along the first path 1151 of the guide rail 1150, and when the brush part 1140 rotates from the second position to the first position, the guide protrusion 1141 of the brush part 1140 moves along the second path 1152 of the guide rail 1150 located radially inside the first path 1151. Therefore, the oscillation radius may differ.

[0185] According to an example embodiment, in response to the guide protrusion 1141 of the brush portion 1140 moving from the first path 1151 to the second path 1152, the rotation axis or rotation radius of the brush portion 1140 can be changed. For example, if the guide protrusion 1141 moves from the first path 1151 to the second path 1152 while the brush portion 1140 is adjacent to the second position, the rotation axis or rotation radius of the brush portion 1140 can be changed. If the guide protrusion 1141 of the brush portion 1140 moves from the first path 1151 to the second path 1152, the rotation radius of the brush portion 1140 can be reduced. Due to the reduction in the rotation radius of the brush portion 1140, the tip portion 1140a of the brush portion 1140 can be spaced apart from the filter member 12. In other words, if the guide protrusion 1141 of the brush portion 1140 moves along the second path 1152, the brush portion 1140 can be spaced apart from the filter member 12, thereby preventing the lint remaining on the surface of the filter member 12 from being swept away in the opposite direction.

[0186] According to an example embodiment, the axis of rotation or radius of rotation of the brush portion 1140 can be changed in response to the guide protrusion 1141 of the brush portion 1140 moving from the second path 1152 to the first path 1151. For example, if the guide protrusion 1141 moves from the second path 1152 to the first path 1151 while the brush portion 1140 is adjacent to a first position, the axis of rotation or radius of rotation of the brush portion 1140 can be changed. If the guide protrusion 1141 of the brush portion 1140 moves from the second path 1152 to the first path 1151, the tip portion 1140a of the brush portion 1140 can be positioned adjacent to the filter member 12. In other words, if the guide protrusion 1141 of the brush portion 1140 moves along the first path 1151, the brush portion 1140 can sweep (e.g., clean or remove) lint adhering to or filtered onto the surface of the filter member 12.

[0187] According to an example embodiment, the brush portion 1140 may include a spring 1145. The spring 1145 may be disposed within the interior space of a guide protrusion 1141 in a recess 1144 formed in the side surface of the brush portion 1140. The spring 1145 may be pressed by the guide protrusion 1141 in the recess 1144 formed in the side surface of the brush portion 1140. The spring 1145 may be configured to apply a spring force to the outside of the guide protrusion 1141. When the brush portion 1140 is mounted or disposed in the housing 1110, the guide protrusion 1141 is disposed on a guide rail 1150 of the housing 1110, and the brush portion 1140 may be configured such that the guide protrusion 1141 is pressed against the guide rail 1150 of the housing 1110 due to the spring force of the spring 1145. For example, the brush portion 1140 may be configured such that the guide protrusion 1141 is pressed (or pressed downwards) against the bottom surface of the guide rail 1150 due to the spring force of the spring 1145.

[0188] According to an example embodiment, the horizontal cross-sectional area of ​​the shaft 1130 may be smaller than the horizontal cross-sectional area of ​​the shaft hole 1142. Due to the difference in horizontal cross-sectional areas between the shaft 1130 and the shaft hole 1142, the brush portion 1140 may be coupled to the shaft 1130 to be movable relative to the shaft 1130. The brush portion 1140 may be coupled to the shaft 1130 such that the shaft 1130 is movable relative to the brush portion 1140. The horizontal cross-section of the shaft 1130 may have a generally elongated shape. However, this disclosure is not limited thereto, and the horizontal cross-section of the shaft 1130 may have, for example, a generally circular shape, an elliptical shape, or a rectangular shape. The horizontal cross-section of the shaft hole 1142 may have a generally elongated shape. However, this disclosure is not limited thereto, and the horizontal cross-section of the shaft hole 1142 may have, for example, a generally elliptical shape or a rectangular shape.

[0189] Figure 14 This is a diagram illustrating an example guide rail structure of a lint removal device according to an embodiment.

[0190] Figure 14 The housing 1110 shown can be with Figure 11 and Figure 12 The housing 1110 shown is substantially the same or similar. Figure 14 The housing 1110 shown may include in Figure 11 and Figure 12 The lint removal device 1100.

[0191] Reference Figure 14 The guide rail 1150 may include a first connecting portion 1153 and a second connecting portion 1154. (e.g., brush portion) Figure 12 The guide protrusion of the brush part 1140 (e.g., Figure 12 The guide protrusion 1141 can move between the first path 1151 and the second path 1152 of the guide rail 1150 via the first connecting part 1153 or the second connecting part 1154.

[0192] The first connecting portion 1153 may be the portion connecting the first path 1151 and the second path 1152 when the brush portion 1140 is set to be adjacent to the first position. The first connecting portion 1153 may be the portion connecting one end 1151a of the first path 1151 to one end 1152a of the second path 1152.

[0193] The second connecting portion 1154 may be the portion connecting the first path 1151 and the second path 1152 when the brush portion 1140 is positioned adjacent to the second position. The second connecting portion 1154 may be the portion connecting the other end 1151b of the first path 1151 to the other end 1152b of the second path 1152. The other end 1151b of the first path 1151 may refer to the end opposite to one end 1151a of the first path 1151. The other end 1152b of the second path 1152 may refer to the end opposite to one end 1152a of the second path 1152.

[0194] According to an example embodiment, in the first connecting portion 1153 of the guide rail 1150, a first step 1155 may be formed at the boundary dividing the first path 1151 and the second path 1152. In the first connecting portion 1153, the second path 1152 may be formed with a step that is higher than the first path 1151. One end 1152a of the second path 1152 may be formed with a step that is higher than the end 1151a of the first path 1151. Here, "upward step" may refer to an upward step in the direction toward the brush portion 1140.

[0195] According to an example embodiment, if the guide protrusion 1141 of the brush portion 1140 moves along the guide rail 1150, the guide protrusion 1141 of the brush portion 1140 can move from the second path 1152 to the first path 1151 at the first connecting portion 1153. Due to the step formed in the first connecting portion 1153, the guide protrusion 1141 can move in only one direction. As described above, due to the spring (e.g., Figure 12 The spring 1145 is pressed (or pressed down) on the bottom surface of the guide rail 1150, so that the guide protrusion 1141 can move in only one direction.

[0196] According to an example embodiment, in the second connecting portion 1154 of the guide rail 1150, a second step 1156 may be formed at the boundary dividing the first path 1151 and the second path 1152. In the second connecting portion 1154, the first path 1151 may be formed with a step that is higher than the second path 1152. The other end 1151b of the first path 1151 may be formed with a step that is higher than the other end 1152b of the second path 1152. Here, "upward step" may refer to an upward step in the direction toward the brush portion 1140.

[0197] When the guide protrusion 1141 of the brush portion 1140 moves along the guide rail 1150, the guide protrusion 1141 of the brush portion 1140 can move from the first path 1151 to the second path 1152 at the second connecting portion 1154. Due to the step formed in the second connecting portion 1154, the guide protrusion 1141 can move in only one direction. As described above, due to the spring (e.g., Figure 12 The spring 1145 is pressed (or pressed down) on the bottom surface of the guide rail 1150, so that the guide protrusion 1141 can move in only one direction.

[0198] Figure 15 This is a graph illustrating an example inclined structure of the guide rail of the lint cleaning device according to an embodiment.

[0199] Figure 15 The graph is used to describe the inclined structure of guide rail 1150.

[0200] Reference Figure 15 The heights of the first path 1151 and the second path 1152 of the guide rail 1150 are shown. Here, the heights of the first path 1151 and the second path 1152 may refer to the thickness of the housing 1110 at the corresponding locations.

[0201] According to an example embodiment, the first path 1151 may be configured to slope upwards along the direction in which the brush portion 1140 moves from the first position to the second position. For example, the first path 1151 may be configured such that its height increases along the direction in which the brush portion 1140 moves from the first position to the second position. For example, the first path 1151 may be configured to slope as the brush portion 1140 moves from the first position to the second position to approach the brush portion 1140.

[0202] According to an example embodiment, the second path 1152 may be configured to slope upwards along the direction in which the brush portion 1140 moves from the second position to the first position. For example, the second path 1152 may be configured such that its height increases along the direction in which the brush portion 1140 moves from the second position to the first position. For example, the second path 1152 may be configured to slope as the brush portion 1140 moves from the second position to the first position to approach the brush portion 1140.

[0203] As shown in the figure, the first path 1151 and the second path 1152 can be formed to be inclined upward in different directions, so that in the first connecting part (e.g., Figure 14 First connecting part 1153) and second connecting part (e.g., Figure 14 A difference in step size is formed at the second connecting part 1154.

[0204] Figures 16a to 16d This is a diagram illustrating an example operation of the lint removal device according to an embodiment.

[0205] Figures 16a to 16d The lint removal device 1100 and its components shown are compatible with Figures 11 to 15 The lint removal device 1100 and its components shown are substantially the same or similar. In the following, the same reference numerals will be assigned to those with reference to the reference numerals. Figures 11 to 15 The components described are essentially the same or similar to the components.

[0206] Figure 16a The diagram illustrates the state of the brush portion 1140 in a first position. When the brush portion 1140 is in the first position, the guide protrusion 1141 of the brush portion 1140 can be positioned on the first path 1151 of the guide rail 1150. For example, the guide protrusion 1141 can be positioned at one end 1151a of the first path 1151. Due to the step formed at the boundary between one end 1151a of the first path 1151 and one end of the second path 1152, the guide protrusion 1141 will not move into the second path 1152. When the brush portion 1140 is in the first position, the shaft 1130 can be disposed in the shaft hole 1142 to be adjacent to the opposite end of the tip portion 1140a of the brush portion 1140.

[0207] Figure 16b An example operation is shown where the lint cleaning device 1100 rotates the brush portion 1140 to clean lint adhering to the filter member 12. As the brush portion 1140 rotates in a first rotation direction, the lint adhering to the filter member 12 can be swept away (e.g., cleaned or removed). A drive (e.g., Figure 11 The motor of the driver 1120 is operable to rotate the brush portion 1140. When the motor of the driver 1120 rotates in a first rotation direction, the shaft 1130 can rotate in the first rotation direction, and the brush portion 1140 coupled to the shaft 1130 can rotate in the first rotation direction. Here, the first rotation direction may refer to the clockwise direction in the figures. When the brush portion 1140 rotates in the first rotation direction, the guide protrusion 1141 can move along the first path 1151 of the guide rail 1150.

[0208] Figure 16cThe state of the brush portion 1140 in the second position is shown. As the brush portion 1140 moves from the first position to the second position, lint adhering to the surface of the filter member 12 can be cleaned. When the brush portion 1140 reaches the second position, the lint swept away by the rotation of the brush portion 1140 can move to a separate lint container (not shown). When the brush portion 1140 reaches the second position, the guide protrusion 1141 can move from the first path 1151 of the guide rail 1150 to the second path 1152. As the guide protrusion 1141 moves from the first path 1151 to the second path 1152, the brush portion 1140 can move such that the shaft 1130 approaches the direction relatively close to the tip portion 1140a of the brush portion 1140 in the shaft hole 1142. Therefore, the rotation radius of the brush portion 1140 can be reduced.

[0209] Figure 16d An example operation is shown whereby the lint removal device 1100 rotates the brush portion 1140 from a second position to a first position after cleaning. The motor of the driver 1120 is operable to rotate the brush portion 1140. When the motor of the driver 1120 rotates in a second rotation direction opposite to the first rotation direction, the brush portion 1140 can rotate in the second rotation direction. Here, the second rotation direction may refer to the counterclockwise direction in the figures. When the brush portion 1140 rotates in the second rotation direction, the guide protrusion 1141 can move along the second path 1152 of the guide rail 1150. Therefore, since the radius of rotation of the brush portion 1140 decreases, the tip portion 1140a of the brush portion 1140 can be spaced apart from the filter member 12 when the brush portion 1140 rotates in the second rotation direction. By separating the brush portion 1140 from the filter member 12 when the brush portion 1140 rotates in the second rotation direction, it is possible to prevent the lint remaining on the surface of the filter member 12 from being swept in the opposite direction along the tip of the brush portion 1140 after cleaning.

[0210] exist Figure 16d In the middle, when the brush unit 1140 reaches the first position, the brush unit 1140 returns to the starting position. Figure 16a The state. For example, as the guide protrusion 1141 moves from the second path 1152 to the first path 1151, when the brush part 1140 reaches the first position, the brush part 1140 can return to the first position. Figure 16a The state.

[0211] Figure 17 This is a perspective view showing an example lint removal device according to an embodiment. Figure 18 This is an exploded perspective view showing an example lint removal device according to an embodiment.

[0212] Figure 17 and Figure 18 The lint removal device 1700 shown can be used with Figure 1 and Figure 2The lint removal device 90 of the garment processing device 1 shown is substantially the same as or similar to that of the garment processing device 1 shown. Figure 17 and Figure 18 The lint removal device 1700 shown may include in Figure 1 and Figure 2 In the clothing processing device 1 shown.

[0213] Figure 17 and Figure 18 The lint removal device 1700 shown can be the same as the one described above. Figures 5 to 10d The technical features of the described lint removal device 500 are the same as those described above. Figures 11 to 16d The technical features of the described lint removal device 1100 are combined in the embodiments.

[0214] Figure 17 and Figure 18 The lint removal device 1700 shown can be installed or set in, for example, Figure 4a and Figure 4b The clothes dryer shown is not limited to clothes dryers, but the clothes handling apparatus 1 described in this disclosure is not limited to clothes dryers. In other words, Figure 17 and Figure 18 The lint removal device 1700 shown may include or may be installed in any device that includes a heat exchanger and is used to contain clothes to be dried in a specific space and to dry and heat the humid air discharged from the specific space.

[0215] According to an example embodiment, the lint removal device 1700 can be modular. The lint removal device 1700 can be installed in a garment processing device (e.g., Figure 4a The garment holding unit of the garment handling device 1) (e.g., Figure 2 Below the roller 20), and can be modularly installed so that it can slide in or out. For example, components of the lint removal device 1700, except for the drive 1720, can be modularly installed or disposed in the garment handling device 1 for removable installation.

[0216] Reference Figure 17 and Figure 18 The lint removal device 1700 may include all or some of the following: housing 1710, actuator 1720, shaft 1730, brush section 1740, lint chamber 1750, chamber door 1760, or operating assembly 1770. In garment handling devices (e.g., Figure 1 During the drying cycle of the garment handling device 1), when air containing lint passes through a filter element (e.g., Figure 2When the filter element 12 is in use, the lint removal device 1700 can automatically clean or remove lint accumulated on the surface of the filter element 12. The lint removal device 1700 can be attached to the filter element 12 to clean or remove lint filtered onto the surface of the filter element 12. When the cleaned lint is contained in the lint chamber 1750 and the lint fills the lint chamber 1750, the garment handling device 1 can detect whether the lint chamber 1750 is full.

[0217] According to an example embodiment, housing 1710 may form the appearance of lint-removing device 1700. Housing 1710 may include receiving spaces for placing components such as brush portion 1740, lint chamber 1750, operating assembly 1770, and chamber door 1760 therein. For example, a first space 1712a may be formed in housing 1710 in which brush portion 1740 rotates to remove lint. For example, a separate second space 1712b may be formed in housing 1710 in which operating assembly 1770 is received. For example, the first space 1712a in which brush portion 1740 is received and the second space 1712b in which operating assembly 1770 is received may be spatially separated (e.g., separated by a partition wall).

[0218] The housing 1710 may form a third space 1712c to accommodate the pile chamber 1750. The third space 1712c may be connected to the first space 1712a. The third space 1712c may be spatially separable from the second space 1712b. The pile chamber 1750 may be removably accommodated in the third space 1712c.

[0219] According to an example embodiment, housing 1710 may include filter mounting portion 1714 or shaft through hole 1715.

[0220] The filter mounting portion 1714 may be a portion configured to mount the filter element 12. The filter mounting portion 1714 may be arranged along the direction of movement of the tip portion 1740a of the brush portion 1740, as described below. The filter mounting portion 1714 may be open to allow air to enter or pass through. The filter element 12 may be mounted or disposed outside or inside the filter mounting portion 1714. For example, the filter mounting portion 1714 may have an arcuate cross-section. The filter mounting portion 1714 may be integrally formed with, but is not limited to, the housing 1710, and may be configured as a separate component integrated into the housing 1710.

[0221] The shaft through hole 1715 can be a portion through which the shaft 1730 to be coupled to the brush portion 1740 passes. The shaft through hole 1715 can be formed as a partition wall that passes through, for example, the first space 1712a and the second space 1712b.

[0222] According to an example embodiment, housing 1710 may include an upper housing 1711, a main housing 1712, and a lower housing 1713. The upper housing 1711 is the portion forming the upper surface of housing 1710 and may be detachably coupled to the main housing 1712. An opening 1711a may be formed in the upper housing 1711. Air can circulate through the opening 1711a of the upper housing 1711. For example, through a garment handling device (e.g., Figure 2 The inlet flow path of the garment handling device 1) (e.g., Figure 2 The air containing lint introduced through the inlet flow path 51) can be introduced into the lint cleaning device 1700 through the opening 1711a. The introduced air can pass through the filter member 12 to filter lint. Unlike what is shown, the upper housing 1711 and the main housing 1712 can be integrally formed.

[0223] The main housing 1712 may be configured to define a first space 1712a, a second space 1712b, and a third space 1712c. For example, the second space 1712b may be located between the main housing 1712 and the lower housing 1713.

[0224] According to an example embodiment, housing 1710 may include guide rail 1780. Figure 17 and Figure 18 The guide rail 1780 shown can be used with Figures 11 to 15 The guide rail 1150 shown is basically the same or similar. Figures 11 to 15 The guide rail 1150 shown can also be applied to Figure 17 and Figure 18 The guide rail is 1780.

[0225] The guide rail 1780 may be formed on the wall surface 1712d of the housing 1710. The guide rail 1780 may be formed, for example, in the form of a groove cut out in the wall surface 1712d of the housing 1710.

[0226] The guide rail 1780 may be formed within the range of motion (described below) of the brush portion 1740 moving between the first position and the second position. The guide rail 1780 may be formed on the partition wall between the first space 1712a and the second space 1712b. For example, the guide rail 1780 may be formed on the partition wall between the first space 1712a and the second space 1712b facing the first space 1712a. The guide rail 1780 may be configured such that the guide protrusion 1741 of the brush portion 1740, described below, is inserted into the guide rail 1780 to guide the movement path of the guide protrusion 1741.

[0227] Reference Figures 19a to 19dThe guide rail 1780 may include a first path 1781 and a second path 1782. The first path 1781 may be, for example, a path for guiding the rotation of the brush portion 1740 when it rotates in a first rotational direction at a first position (described below). The second path 1782 may be, for example, a path for guiding the rotation of the brush portion 1740 when it rotates in a second rotational direction at a second position (described below). Each of the first path 1781 and the second path 1782 may be formed in an arc shape. The brush portion 1740 may rotate along either the first path 1781 or the second path 1782.

[0228] According to an example embodiment, the first path 1781 may be positioned radially outward compared to the second path 1782. The radius of the first path 1781 may be larger than the radius of the second path 1782.

[0229] According to an example embodiment, the first path 1781 and the second path 1782 may be connected to each other. The guide protrusion 1741 of the brush portion 1740, described below, can move between the first path 1781 and the second path 1782 via a connecting portion. For example, one end 1781a of the first path 1781 may be connected to one end 1782a of the second path 1782. For example, the other end 1781b of the first path 1781 may be connected to the other end 1782b of the second path 1782.

[0230] According to an example embodiment, the guide rail 1780 may include a first connecting portion 1783 and a second connecting portion 1784. The guide protrusion 1741 of the brush portion 1740 may move between a first path 1781 and a second path 1782 of the guide rail 1780 via the first connecting portion 1783 or the second connecting portion 1784.

[0231] The first connecting portion 1783 may be the portion connecting the first path 1781 and the second path 1782 when the brush portion 1740 is set to be adjacent to the first position. The first connecting portion 1783 may be the portion connecting one end 1781a of the first path 1781 to one end 1782a of the second path 1782.

[0232] The second connecting portion 1784 may be the portion connecting the first path 1781 and the second path 1782 when the brush portion 1740 is positioned adjacent to the second position. The second connecting portion 1784 may be the portion connecting the other end 1781b of the first path 1781 to the other end 1782b of the second path 1782. The other end 1781b of the first path 1781 may refer to the end opposite to one end 1781a of the first path 1781. The other end 1782b of the second path 1782 may refer to the end opposite to one end 1782a of the second path 1782.

[0233] According to an example embodiment, in the first connecting portion 1783 of the guide rail 1780, a step may be formed at the boundary dividing the first path 1781 and the second path 1782. In the first connecting portion 1783, the second path 1782 may be formed with a step that is higher than the first path 1781. One end 1782a of the second path 1782 may be formed with a step that is higher than the end 1781a of the first path 1781. Here, "upward step" may refer to an upward step in the direction toward the brush portion 1740.

[0234] According to the example embodiment, when the guide protrusion 1741 of the brush portion 1740 moves along the guide rail 1780, the guide protrusion 1741 of the brush portion 1740 can move from the second path 1782 to the first path 1781 at the first connecting portion 1783. Due to the step formed in the first connecting portion 1783, the guide protrusion 1741 can move in only one direction. As described above, since the guide protrusion 1741 is pressed (or pressed downward) on the bottom surface of the guide rail 1780 by the spring 1745, the guide protrusion 1741 can move in only one direction.

[0235] According to an example embodiment, in the second connecting portion 1784 of the guide rail 1780, a step may be formed at the boundary dividing the first path 1781 and the second path 1782. In the second connecting portion 1784, the first path 1781 may be formed with an upward step compared to the second path 1782. The other end 1781b of the first path 1781 may be formed with an upward step compared to the other end 1782b of the second path 1782. Here, "upward step" may refer to an upward step in the direction toward the brush portion 1740.

[0236] When the guide protrusion 1741 of the brush portion 1740 moves along the guide rail 1780, the guide protrusion 1741 of the brush portion 1740 can move from the first path 1781 to the second path 1782 at the second connecting portion 1784. Due to the step formed in the second connecting portion 1784, the guide protrusion 1741 can move in only one direction. As described above, since the guide protrusion 1741 is pressed (or pressed downward) against the bottom surface of the guide rail 1780 by the spring 1745, the guide protrusion 1741 can move in only one direction.

[0237] According to an example embodiment, the first path 1781 may be configured to slope upwards along the direction in which the brush portion 1740 moves from the first position to the second position. For example, the first path 1781 may be configured such that its height increases along the direction in which the brush portion 1740 moves from the first position to the second position. For example, the first path 1781 may be configured to slope as the brush portion 1740 moves from the first position to the second position to approach the brush portion 1740.

[0238] According to an example embodiment, the second path 1782 may be configured to slope upwards along the direction in which the brush portion 1740 moves from the second position to the first position. For example, the second path 1782 may be configured such that its height increases along the direction in which the brush portion 1740 moves from the second position to the first position. For example, the second path 1782 may be configured to slope as the brush portion 1740 moves from the second position to the first position to approach the brush portion 1740.

[0239] As shown in the figure, the first path 1781 and the second path 1782 can be formed to be inclined upward in different directions, thereby creating a difference in step size at the first connecting part 1783 and the second connecting part 1784.

[0240] According to an example embodiment, the actuator 1720 may be configured to rotate the brush section 1740 and the chamber door 1760. In this disclosure, an operating structure may be configured to sequentially open and close the brush section 1740 and the chamber door 1760 using a single actuator 1720. The brush section 1740 and the chamber door 1760 may rotate due to the rotation of a motor disposed in the actuator 1720. For example, the rotational power of the actuator 1720 may be directly transmitted to the brush section 1740. Here, direct transmission of rotational power can mean not only that the actuator 1720 and the brush section 1740 are directly coupled to each other, but also that even if the motor of the actuator 1720 and the brush section 1740 are indirectly coupled to each other, the rotational power is transmitted such that the angle of rotation of the motor of the actuator 1720 is substantially the same as the angle of rotation of the brush section 1740.

[0241] According to an example embodiment, shaft 1730 may be configured to connect driver 1720 and brush portion 1740. Shaft 1730 may be coupled to the rotating shaft of driver 1720 and may be coupled to brush portion 1740 through shaft through hole 1715 of housing 1710. Shaft 1730 may be coupled to brush portion 1740 by insertion into shaft hole 1742 of brush portion 1740, which will be described below.

[0242] According to an example embodiment, the brush portion 1740 may be configured to rotate between a first position and a second position. Figure 17 and Figure 18 The brush section 1740 shown can be connected to Figures 11 to 13 The brush section 1140 shown is substantially the same as or similar to the brush section shown. Figures 11 to 13 The description of the brush section 1140 shown can also be applied to... Figure 17 and Figure 18 The brush part is 1740.

[0243] The brush portion 1740 can be configured to sweep (e.g., clean or remove) lint adhering to the filter member 12 by rotating about a rotation axis. The brush portion 1740 can be configured such that the tip portion 1740a rotates along the inner circumferential surface of the filter member 12. As the brush portion 1740 rotates, the tip portion 1740a of the brush portion 1740 can be positioned adjacent to the inner circumferential surface of the filter member 12 to clean the lint adhering to the filter member 12. Here, the rotation axis of the brush portion 1740 can be the same axis as the rotation axis of the shaft 1730. Here, the first position can refer to the position before the brush portion 1740 begins cleaning the lint. Here, the second position can refer to the position where the brush portion 1740 rotates from the first position to complete cleaning the lint adhering to the filter member 12. The second position can be a position relatively closer to the chamber door 1760 than the first position. The second position can be a position relatively closer to the lint chamber 1750 than the first position.

[0244] The brush portion 1740 can rotate reciprocally between a first position and a second position. For example, if the motor of the driver 1720 rotates in a first direction of rotation (e.g., forward or clockwise), the brush portion 1740 can rotate in a direction from the first position toward the second position. The brush portion 1740 can move from the first position to the second position to clean (or remove) lint from the filter member 12, and when it reaches the second position, it delivers lint to the lint chamber 1750.

[0245] When the motor of the driver 1720 rotates in a second rotation direction opposite to the first rotation direction (e.g., in the opposite or counterclockwise direction), the brush portion 1740 can rotate from the second position toward the first position. For example, if the motor of the driver 1720 rotates in the second rotation direction, the brush portion 1740 can also rotate in the second rotation direction. However, this disclosure is not limited thereto, and the rotation direction of the motor of the driver 1720 and the rotation direction of the brush portion 1740 may be opposite to the directions shown. The brush portion 1740 may be referred to as a "wiper," "scraper," or "blade."

[0246] According to an example embodiment, the brush portion 1740 may include an elastomer 1743 formed of an elastic material or rubber material. The elastomer 1743 may be disposed on the tip portion 1740a of the brush portion 1740. The elastomer 1743 may be a portion positioned adjacent to the inner peripheral surface of the filter member 12 when the brush portion 1740 rotates. The tip portion 1740a of the brush portion 1740 may be formed using the elastomer 1743, thereby preventing damage to the filter member 12 when the brush portion 1740 rotates.

[0247] According to an example embodiment, the brush portion 1740 may include a guide protrusion 1741 that is inserted into at least partially protruding from a side surface of the brush portion 1740. At least a portion of the guide protrusion 1741 may be inserted into a recess 1744 formed in a side surface of the brush portion 1740. If the brush portion 1740 rotates, the guide protrusion 1741 may move along a path formed by a guide rail 1780 of the housing 1710.

[0248] According to the example embodiment, when the brush portion 1740 rotates from the second position to the first position, the tip portion 1740a can be spaced apart from the filter member 12. For example, when the brush portion 1740 rotates from the second position to the first position, the guide protrusion 1741 can move to the second path 1782, the oscillation radius of the second path 1782 being smaller than the oscillation radius of the first path 1781. Therefore, the brush portion 1740 can rotate while being spaced apart from the filter member 12.

[0249] According to an example embodiment, the brush portion 1740 may include a shaft hole 1742. A shaft 1730 may be inserted into the shaft hole 1742 to form a rotation axis. The brush portion 1740 may use the shaft 1730 as a rotation axis to rotate between a first position and a second position.

[0250] According to an example embodiment, the shaft hole 1742 may be formed such that the shaft 1730 can move relative to it. The shaft 1730 may be inserted to be movable within the shaft hole 1742. The shaft hole 1742 may be configured such that the shaft 1730 can move within it in one direction. For example, the shaft hole 1742 may be configured such that the shaft 1730 can move within an arc-shaped filter member (e.g., Figure 2 The filter element 12) moves relative to the filter element in the radial direction. The brush part 1740 can move in one direction while the shaft 1730 is fixed. From a relative viewpoint with respect to the brush part 1740, the shaft 1730 can move in one direction within the shaft hole 1742.

[0251] According to an example embodiment, the axis of rotation or radius of rotation of the brush portion 1740 can be changed when the shaft 1730 moves relative to the shaft hole 1742. According to an example embodiment, the lint removal device 1700 can be configured such that the axis of rotation or radius of rotation of the brush portion 1740 varies depending on the relative position of the shaft 1730 with respect to the shaft hole 1742. The shaft 1730 can be fixedly disposed, and the brush portion 1740 can be configured to move due to additional space provided in the shaft hole 1742. From a relative perspective, the shaft 1730 can move relative to the brush portion 1740. In the shaft hole 1742, when the shaft 1730 is positioned relative to the tip portion 1740a adjacent to the brush portion 1740, the oscillation radius of the brush portion 1740 can be reduced. In the shaft hole 1742, when the shaft 1730 is positioned relative to the tip portion 1740a away from the brush portion 1740, the oscillation radius of the brush portion 1740 can be increased.

[0252] According to the example embodiment, when the brush part 1140 rotates from the first position to the second position, the rotation radius of the brush part 1740 may be greater than the rotation radius of the brush part 1140 when it rotates from the second position to the first position. When the brush part 1740 rotates from the first position to the second position, the guide protrusion 1741 of the brush part 1740 may move along the first path 1781 of the guide rail 1780, and when the brush part 1740 rotates from the second position to the first position, the guide protrusion 1741 of the brush part 1740 may move along the second path 1782 of the guide rail 1780 located radially inside the first path 1781, so the swing radius may differ.

[0253] According to an example embodiment, in response to the guide protrusion 1741 of the brush portion 1740 moving from the first path 1781 to the second path 1782, the rotation axis or rotation radius of the brush portion 1740 can be changed. For example, when the brush portion 1740 is positioned adjacent to the second position, and the guide protrusion 1741 moves from the first path 1781 to the second path 1782, the rotation axis or rotation radius of the brush portion 1740 can be changed. When the guide protrusion 1741 of the brush portion 1740 moves from the first path 1781 to the second path 1782, the rotation radius of the brush portion 1740 can be reduced. Due to the reduction in the rotation radius of the brush portion 1740, the tip portion 1740a of the brush portion 1740 can be spaced apart from the filter member 12. In other words, when the guide protrusion 1741 of the brush portion 1740 moves along the second path 1782, the brush portion 1740 can be spaced apart from the filter member 12, thereby preventing the lint remaining on the surface of the filter member 12 from being swept or removed in the opposite direction.

[0254] According to an example embodiment, in response to the guide protrusion 1741 of the brush portion 1740 moving from the second path 1782 to the first path 1781, the axis of rotation or radius of rotation of the brush portion 1740 can be changed. For example, when the brush portion 1740 is positioned adjacent to a first position, the axis of rotation or radius of rotation of the brush portion 1740 can be changed when the guide protrusion 1741 moves from the second path 1782 to the first path 1781. When the guide protrusion 1741 of the brush portion 1740 moves from the second path 1782 to the first path 1781, the tip portion 1740a of the brush portion 1740 can be adjacent to the filter member 12. In other words, when the guide protrusion 1741 of the brush portion 1740 moves along the first path 1781, the brush portion 1740 can sweep away lint adhering to or filtered on the surface of the filter member 12.

[0255] According to an example embodiment, the brush portion 1740 may include a spring 1745. The spring 1745 may be disposed within the interior space of a guide protrusion 1741 in a recess 1744 formed in the side surface of the brush portion 1740. The spring 1745 may be pressed by the guide protrusion 1741 in the recess 1744 formed in the side surface of the brush portion 1740. The spring 1745 may be configured to apply a resilient force to the outside of the guide protrusion 1741. If the brush portion 1740 is mounted or disposed in the housing 1710, the guide protrusion 1741 is disposed on a guide rail 1780 of the housing 1710, and the brush portion 1740 may be configured such that the guide protrusion 1741 is pressed against the guide rail 1780 of the housing 1710 due to the spring 1745. For example, the brush portion 1740 may be configured such that the guide protrusion 1741 is pressed (or pressed downwards) against the bottom surface of the guide rail 1780 due to the resilient force of the spring 1745.

[0256] According to an example embodiment, the horizontal cross-sectional area of ​​the shaft 1730 may be smaller than the horizontal cross-sectional area of ​​the shaft hole 1742. Due to the difference in horizontal cross-sectional areas between the shaft 1730 and the shaft hole 1742, the brush portion 1740 may be coupled to the shaft 1730 to be movable relative to the shaft 1730. The brush portion 1740 may be coupled to the shaft 1730 such that the shaft 1730 is movable relative to the brush portion 1740. The horizontal cross-section of the shaft 1730 may have a generally elongated shape. However, this disclosure is not limited thereto, and the horizontal cross-section of the shaft 1730 may have, for example, a generally circular shape, an elliptical shape, or a rectangular shape. The horizontal cross-section of the shaft hole 1742 may have a generally elongated shape. However, this disclosure is not limited thereto, and the horizontal cross-section of the shaft hole 1742 may have, for example, a generally elliptical shape or a rectangular shape.

[0257] According to an example embodiment, the lint chamber 1750 may be configured to contain lint removed by the brush section 1740. Lint swept or removed by the rotation of the brush section 1740 may be conveyed into the lint chamber 1750.

[0258] According to an example embodiment, the lint chamber 1750 may include a lint inlet 1750a. Lint swept up by the rotation of the brush portion 1740 can pass through the lint inlet 1750a and be accommodated in the lint chamber 1750. When the lint chamber 1750 is installed in the housing 1710, the lint inlet 1750a may be located between the first space 1712a and the third space 1712c of the housing 1710.

[0259] The lint chamber 1750 may be accommodated in the third space 1712c of the housing 1710. The lint chamber 1750 may slide into or out of the housing 1710. If the lint chamber 1750 is filled (e.g., partially or completely filled) with lint, the user may separate the lint chamber 1750 to remove the lint.

[0260] According to an example embodiment, chamber door 1760 may be configured to open or close the fluff chamber 1750. Chamber door 1760 may be mounted in housing 1710. Chamber door 1760 may be configured to open or close the portion of housing 1710 connected between the first space 1712a and the third space 1712c. If chamber door 1760 is open, chamber door 560 may be opened by moving it toward brush portion 1740. For example, if chamber door 1760 is open, chamber door 560 may be opened by moving it toward the first space 1712a. Chamber door 1760 may be opened / closed by receiving power from actuator 1720 via operating assembly 1770, which will be described below. Chamber door 1760 may be referred to as an opening / closing plate. The chamber door 1760 can separate the space in which the brush section 1740 cleans the lint from the space in the lint chamber 1750, thereby preventing the lint in the lint chamber 1750 from flowing back into the first space 1712a that houses the brush section 1740 and contaminating the interior.

[0261] According to an example embodiment, the chamber door 1760 may include a rotation shaft 1761. The rotation shaft 1761 of the chamber door 1760 may be fixed by the housing 1710 for movements other than rotation. For example, the rotation shaft of the chamber door 1760 may be rotatably coupled to the upper housing 1711 and the main housing 1712.

[0262] According to an example embodiment, the operating assembly 1770 may be configured to move the chamber door 1760 in response to operation of the actuator. Figure 17 and Figure 18 The operating assembly 1770 shown can be used with Figures 5 to 10d The operating assembly 570 shown is substantially the same or similar. Figures 5 to 10d The description of the operating assembly 570 shown can also be applied to... Figure 17 and Figure 18 Operating assembly 1770.

[0263] The operating assembly 1770 can be accommodated in the second space 1712b of the housing 1710. The operating assembly 1770 can be configured such that the direction of movement of the chamber door 1760 changes according to the rotation direction of the motor of the actuator 1720. For example, if the motor of the actuator 1720 rotates in a first rotation direction, the chamber door 1760 can open the fluff chamber 1750. For example, if the motor of the actuator 1720 rotates in a second rotation direction, the chamber door 1760 can close the fluff chamber 1750.

[0264] According to an example embodiment, the operating assembly 1770 may include a cam 1771 coupled to the actuator 1720, a lever 1772 configured to rotate in response to rotation of the cam 1771, and a latch 1773 configured to rotate in response to rotation of the lever 1772. Each of the cam 1771, lever 1772, and latch 1773 may be accommodated in a second space 1712b of the housing 1710.

[0265] Cam 1771 can be rotatably coupled to driver 1720. Cam 1771 can be coupled to the rotating shaft of a motor, such as driver 1720, and can rotate according to the operation of the motor. Cam 1771 can be disposed between shaft 1730 and driver 1720.

[0266] According to an example embodiment, the cam 1771 may include a first pressing protrusion 1771a, a second pressing protrusion 1771b spaced circumferentially from the first pressing protrusion 1771a, and a recess 1771c formed between the first pressing protrusion 1771a and the second pressing protrusion 1771b. The first pressing protrusion 1771a can rotate the lever 1772 by pressing the lever 1772. The second pressing protrusion 1771b can rotate the lever 1772 by pressing the lever 1772.

[0267] The first pressing protrusion 1771a and the second pressing protrusion 1771b may have substantially the same radius, but are not limited thereto. The first pressing protrusion 1771a and the second pressing protrusion 1771b may protrude to be spaced substantially the same distance from the axis of rotation. The first pressing protrusion 1771a may protrude while maintaining a constant radius in the circumferential direction, but is not limited thereto. The second pressing protrusion 1771b may protrude while maintaining a constant radius in the circumferential direction, but is not limited thereto.

[0268] As shown in the figure, the circumferential length of the first pressing protrusion 1771a may be shorter than the circumferential length of the second pressing protrusion 1771b. However, this disclosure is not limited thereto, and unlike what is shown, the circumferential length of the first pressing protrusion 1771a may be equal to or greater than the circumferential length of the second pressing protrusion 1771b.

[0269] According to an example embodiment, a recess 1771c may be formed between a first pressing protrusion 1771a and a second pressing protrusion 1771b. The radius of the recess 1771c may be smaller than the radius of the first pressing protrusion 1771a or the radius of the second pressing protrusion 1771b.

[0270] The lever 1772 may include a lever protrusion 1772a formed to project toward the cam 1771. The lever protrusion 1772a may be a portion pressed by a first pressing protrusion 1771a or a second pressing protrusion 1771b of the cam 1771. If the lever protrusion 1772a is pressed by the first pressing protrusion 1771a or the second pressing protrusion 1771b of the cam 1771, the lever 1772 may not be pressed by the cam 1771.

[0271] If lever 1772 is pressed by the pressing protrusion 1771a or 1771b of cam 1771 and rotated in one direction, latch 1773 engaged with lever 1772 may rotate in response.

[0272] The latch 1773 may be configured to rotate in response to rotation of the lever 1772. The latch 1773 may be configured to open or close the chamber door 1760. The chamber door 1760 may rotate together with the latch 1773.

[0273] The operating assembly 1770 may also include a first spring 1774 disposed between the housing 1710 and the rod 1772. The elastic force of the first spring 1774 can be applied to the rod 1772 in the direction along which the chamber door 1760 is closed by rotation of the rod 1772.

[0274] The operating assembly 1770 may also include a second spring 1775 disposed between the housing 1710 and the latch 1773. The spring force of the second spring 1775 can apply a force to the latch 1773 in the direction along which the chamber door 1760 is opened.

[0275] According to the example embodiment, the elastic modulus of the first spring 1774 may be less than that of the elastic modulus of the second spring 1775, but is not limited thereto.

[0276] A detailed description of the operating methods and procedures for assembly 1770 will be provided by [the relevant authority / organization]. Figures 9a to 9e The description is replaced by [the description].

[0277] According to an example embodiment, the lint removal device 1700 may include a filter member 12. The filter member 12 may be mounted or disposed on a filter mounting portion 1714 of the housing 1710. The filter member 12 may have a curved shape. The filter member 12 may have, for example, a cylindrical shape in which some of its side surfaces are open. The filter member 12 may have, for example, an arcuate shape. However, this disclosure is not limited thereto, and the filter member 12 may be omitted from the lint removal device 1700 and may be separately disposed and mounted on the filter mounting portion 1714.

[0278] According to an example embodiment, a garment handling device (e.g., Figure 1 The garment handling device 1) may also include a sensor (not shown) configured to detect whether the fluff chamber is filled with fluff.

[0279] For example, the sensor could be a current sensor that detects the current flowing through the motor of the driver 1720. If the lint chamber 1750 is full of lint, a greater force may be needed to close the chamber door 1760 due to the reaction force of the lint. When a greater force is required, a greater load can be generated on the motor. The garment handling apparatus 1 can estimate the load on the motor of the driver 1720 based on the current value sensed by the current sensor, and if the load on the motor exceeds a set value, the garment handling apparatus 1 can determine that the lint chamber 1750 is full.

[0280] For example, the sensor could be a reed switch. If a reed switch is used as the sensor, a magnetizing device can be provided in a portion of the chamber door 1760. The reed switch can be integrated into the housing 1710 to detect the magnetizing device when the chamber door 1760 is closed. If the reed switch detects the magnetizing device, the garment handling apparatus 1 can determine that the chamber door 1760 is closed. If the fluff chamber 1750 is full of fluff, the chamber door 1760 may not be able to close completely due to the pressure of the fluff. In this case, since no magnetizing device is detected by the reed switch, the garment handling apparatus 1 can determine that the fluff chamber 1750 is full of fluff. The magnetizing device can include, for example, a common magnet or an electromagnet, but is not limited thereto. The reed switch can detect the magnetizing device.

[0281] Figures 19a to 19d This is a diagram illustrating an example operation of the lint removal device according to an embodiment.

[0282] Figures 19a to 19d The lint removal device 1700 and its components shown are compatible with Figure 17 and Figure 18 The lint removal device 1700 and its components shown are substantially the same or similar. In the following, the same reference numerals will be assigned to those with reference to the reference numerals. Figure 17 and Figure 18 The components described are essentially the same or similar to the components.

[0283] Figures 19a to 19d The process of organically operating the brush section 1740 and the chamber door 1760 in the lint cleaning device 1700 by operating the actuator 1720 is shown. Figures 19a to 19d The description of the operation process of the lint removal device 1700 and the operation process of the operating assembly 1770 will be provided by [the relevant authority / organization]. Figures 9a to 9e The description is replaced by [the description].

[0284] Figure 19a The brush section 1740 is shown in the first position. If the brush section 1740 is in the first position, the chamber door 1760 can separate the space between the first space 1712a and the fluff chamber 1750 in the closed state. Figure 19a This can be the state in which the lint removal device 1700 remains when cleaning lint adhering to the filter element 12 is not performed. If the brush section 1740 is in the first state, the operating assembly 1770 can remain in the first state. Figure 9a The state shown in the image.

[0285] Figure 19a The diagram shows the brush portion 1740 in a first position. When the brush portion 1740 is in the first position, the guide protrusion 1741 of the brush portion 1740 can be positioned on the first path 1781 of the guide rail 1780. For example, the guide protrusion 1741 can be positioned at one end 1781a of the first path 1781. Due to the step formed at the boundary between one end 1781a of the first path 1781 and one end 1782a of the second path 1782, the guide protrusion 1741 will not move into the second path 1782. When the brush portion 1740 is in the first position, the shaft 1730 can be disposed in the shaft hole 1742, positioned adjacent to the opposite end of the tip portion 1740a of the brush portion 1740.

[0286] Figure 19b The diagram illustrates the initial operation of the lint-removing device 1700, configured to rotate the brush portion 1740 to remove lint adhering to the filter member 12. The actuator (e.g., Figure 17 The motor of the driver 1720 is operable to rotate the brush section 1740 and the cam 1771. When the motor of the driver 1720 rotates in a first rotation direction, the brush section 1740 and the cam 1771 can rotate in the first rotation direction. When the brush section 1740 rotates in the first rotation direction, the lint attached to the filter member 12 can be swept away (e.g., cleaned or removed). Here, the first rotation direction may refer to the clockwise direction in the figures. The chamber door 1760 can be opened in advance before the brush section 1740 reaches the second position. For example, as Figure 9bAs shown, because the chamber door 1760 opens when the lever 1772 is pressed by the second pressing protrusion 1771b of the cam 1771, the chamber door 1760 can open before the brush portion 1740 reaches the second position. The chamber door 1760 can be opened by a latch 1773 that rotates in response to the rotation of the cam 1771. (See reference...) Figure 9b and Figure 9c Detailed description Figure 19b The mechanism of the operating assembly 1770 in the state shown.

[0287] Figure 19b The diagram illustrates the operation of the lint removal device 1700, which rotates the brush portion 1740 to remove lint adhering to the filter element 12. As the brush portion 1740 rotates in a first rotation direction, the lint adhering to the filter element 12 can be swept away (e.g., cleaned or removed). A drive (e.g., Figure 17 The motor of the driver 1720 is operable to rotate the brush portion 1740. When the motor of the driver 1720 rotates in a first rotation direction, the shaft 1730 can rotate in the first rotation direction, and the brush portion 1740 coupled to the shaft 1730 can rotate in the first rotation direction. Here, the first rotation direction may refer to the clockwise direction in the figures. When the brush portion 1740 rotates in the first rotation direction, the guide protrusion 1741 can move along the first path 1781 of the guide rail 1780.

[0288] Figure 19c The diagram shows the brush section 1740 in its second position. As the brush section 1740 moves from the first position to the second position, it cleans lint adhering to the surface of the filter member 12. Lint is cleaned or removed by the rotation of the brush section 1740, and the chamber door 1760 remains open when the brush section 1740 reaches the second position. The lint cleaned by the brush section 1740 can reside in the space between the open chamber door 1760 and the lint chamber 1750. (See reference...) Figure 9d Detailed description Figure 19c The mechanism of the operating assembly 1770 in the state shown.

[0289] Figure 19cThe state of the brush portion 1740 in the second position is shown. As the brush portion 1740 moves from the first position to the second position, lint adhering to the surface of the filter member 12 can be cleaned. When the brush portion 1740 reaches the second position, the lint swept away by the rotation of the brush portion 1740 can move to a separate lint container (not shown). If the brush portion 1740 reaches the second position, the guide protrusion 1741 can move from the first path 1781 of the guide rail 1780 to the second path 1782. If the guide protrusion 1741 moves from the first path 1781 to the second path 1782, the brush portion 1740 can be moved such that the shaft 1730 approaches the direction relatively close to the tip portion 1740a of the brush portion 1740 in the shaft hole 1742. Therefore, the rotation radius of the brush portion 1740 can be reduced.

[0290] Figure 19d The diagram illustrates the operation of the lint-removing device 1700 rotating the brush section 1740 from a second position to a first position after cleaning. The motor of the driver 1720 is operable to rotate the brush section 1740 and the cam 1771. When the motor of the driver 1720 rotates in a second rotation direction opposite to the first rotation direction, the brush section 1740 and the cam 1771 can rotate in the second rotation direction. Here, the second rotation direction may refer to the counterclockwise direction shown in the diagram. The chamber door 1760 can be closed before the brush section 1740 reaches the first position. For example, as... Figure 9e As shown, because the lever 1772 is pressed by the second pressing protrusion 1771b of the cam 1771, the chamber door 1760 is closed, so the chamber door 1760 can close before the brush portion 1740 reaches the first position. For example, when the brush portion 1740 begins to rotate in the second rotation direction in the second position, the chamber door 1760 can close the fluff chamber 1750. For example, when the brush portion 1740 is still near the second position, the chamber door 1760 can close the fluff chamber 1750. By spatially separating the space in which the brush portion 1740 moves from the fluff chamber 1750, it is possible to prevent the fluff contained in the fluff chamber 1750 from being discharged back into the first space 1712a. The chamber door 1760 can be opened by a latch 1773 that rotates in response to the rotation of the cam 1771. See reference. Figure 9e Detailed description Figure 19d The mechanism of the operating assembly 1770 in the state shown.

[0291] Figure 19dThe diagram illustrates the operation of the lint removal device 1700 rotating the brush portion 1740 from a second position to a first position after cleaning. The motor of the driver 1720 is operable to rotate the brush portion 1740. When the motor of the driver 1720 rotates in a second rotation direction opposite to the first rotation direction, the brush portion 1740 can rotate in the second rotation direction. Here, the second rotation direction may refer to the counterclockwise direction in the figures. When the brush portion 1740 rotates in the second rotation direction, the guide protrusion 1741 can move along the second path 1782 of the guide rail 1780. Therefore, due to the reduced radius of rotation of the brush portion 1740, the tip portion 1740a of the brush portion 1740 can be spaced apart from the filter member 12 when the brush portion 1740 rotates in the second rotation direction. By separating the brush portion 1740 from the filter member 12 when the brush portion 1740 rotates in the second rotation direction, it is possible to prevent the lint remaining on the surface of the filter member 12 from being swept away (e.g., removed) in the opposite direction along the tip portion of the brush portion 1740 after cleaning.

[0292] If the brush reaches 1740 Figure 19d The first position in the middle, then brush 1140 returns to Figure 19a The state. For example, as the guide protrusion 1741 moves from the second path 1782 to the first path 1781, if the brush part 1740 reaches the first position, the brush part 1140 can return to the first position. Figure 19a The state.

[0293] The lint removal device 1700 may include the operating assembly 1770 as described above, and the operation of the brush section 1740 and the chamber door 1760 can be organically controlled using a single drive 1720 (or actuator). By minimizing the number of drives 1720, the lint removal device 1700 can facilitate the operation of garment handling devices (e.g., Figure 1 The volume occupied by the lint removal device 1700 in the limited internal space of the garment processing device 1) is minimized and the manufacturing cost is reduced.
