[0054] An embodiment of the present application provides a laundry treatment device 1. Please refer to Figure 7 and Figure 8 , which includes a drum assembly 11, a cabinet 12, an air duct 13a, and a filtering device 10.

[0055] The drum assembly 11 has a laundry treatment chamber 11a, an air inlet, and an air outlet. The drum assembly 11 is disposed inside the cabinet 12.

[0056] The air duct 13a is communicated with the air outlet. That is to say, the air flow enters the laundry treatment chamber 11a from the air inlet, and the air flow in the laundry treatment chamber 11a is discharged from the air outlet and enters the air duct 13a.

[0057] It should be noted that in some embodiments, the air flow in the air duct 13a has two paths and can be directly discharged to the atmospheric environment (for example, indoors or outdoors). That is to say, the air flow in the air duct 13a will not enter the laundry treatment chamber 11a again. In other embodiments, the air duct 13a is communicated with the air inlet and the air outlet to form a circulating air duct 13a with the laundry treatment chamber 11a.

[0058] The laundry treatment device 1 can be a dryer, a washing and drying integrated machine, etc., which is not limited herein.

[0059] Exemplarily, taking the air duct 13a being communicated with the air inlet and the air outlet as an example, the principle of drying clothes by the laundry treatment device 1 is as follows: The dry hot air flow in the air duct 13a enters the laundry treatment chamber 11a from the air inlet at the downstream along the air flow direction in the air duct 13a. In the laundry treatment chamber 11a, the dry hot air flow flows through the surface of the wet clothes, performs heat and moisture exchange with the wet clothes, absorbs the moisture in the clothes, and becomes hot and humid air flow. The hot and humid air flow enters the upstream of the air duct 13a through the air outlet, and successively flows through a condensation dehumidifying member and a heating member. In the process of flowing through the condensation dehumidifying member, the water vapor in the hot and humid air flow precipitates from the air flow due to temperature reduction and condenses into water droplets. After the hot and humid air flow is condensed and dehumidified by the condensation dehumidifying member, it forms a low-temperature dry air flow. When the low-temperature dry air flow passes through the heating member, it is heated into a dry hot air flow. The dry hot air flow enters the laundry treatment chamber 11a again from the downstream of the air duct 13a, and circulates in this way to achieve continuous and efficient drying of the clothes.

[0060] It should be noted that the low-temperature dry air flow is relative to the hot and humid air flow, and the temperature of the low-temperature dry air flow is lower than that of the hot and humid air flow. The low temperature in the embodiments of the present application can be room temperature.

[0061] In some embodiments, the condensation dehumidifying member can be an evaporator 15 in a heat pump system, and the heating member can be a condenser 16 in a heat pump system. In other embodiments, the condensation dehumidifying member can condense and dehumidify the air flow through condensed water, and the heating member can be resistance wire heating, etc.

[0062] The filtering device 10 is arranged on the air flow path of the air duct 13a and can be pulled and moved in the first horizontal direction.

[0063] In some embodiments, the first horizontal direction can be the front-back direction, the left-right direction of the laundry treatment device 1, or any direction between the front-back direction and the left-right direction.

[0064] In the embodiments of the present application, the first horizontal direction is taken as an example of the front-back direction for description. Among them, the first horizontal direction includes the direction from front to back and also the direction from back to front.

[0065] Please refer to Figure 1 , the filtering device 10 includes: a box body 101, a first filtering component 102, and a cleaning component 103.

[0066] The filtering device 10 is slidably arranged on the air flow path of the air duct 13a for filtering impurities in the air flow passing through the air duct 13a. The filtering device 10 can be pulled and moved in the first horizontal direction. Specifically, the filtering device 10 is pulled away from the air duct 13a along the first side of the first horizontal direction and can be inserted into the air duct 13a along the second side of the first horizontal direction. Among them, the first side and the second side are two opposite directions of the first horizontal direction.

[0067] Please refer to Figure 1 , the box body 101 has a receiving space 101a, an air inlet 101b, and an air outlet 101c. The receiving space 101a communicates with the air inlet 101b and the air outlet 101c. It can be understood that the air flow entering the box body 101 flows into the receiving space 101a through the air inlet 101b and then flows out through the air outlet 101c. The first filtering component 102 is arranged in the box body 101 for filtering the air flow passing through the box body 101.

[0068] The air inlet 101b and the air outlet 101c are respectively located on the side walls of different sides of the box body 101. In this way. The area of the side wall of the box body 101 can be fully utilized, so that the opening areas of the air inlet 101b and the air outlet 101c are relatively large, improving the air flow rate, the filtering area, and the filtering efficiency.

[0069] It should be noted that the side wall refers to the side wall corresponding to the receiving space 101a of the box body 101, including the top wall and the bottom wall of the box body along the height direction, and the circumferential side walls along the first horizontal direction and the second horizontal direction.

[0070] The first filtering component 102 and / or the cleaning component 103 is arranged on the box body 101. In this way, the box body can provide an installation space and installation support for the first filtering component 102 and / or the cleaning component 103.

[0071] The cleaning component 103 is used to move along a horizontal plane to clean the first filtering component 102. In some embodiments, the cleaning component 103 is disposed in the box body 101. When the box body 101 is pulled, the box body 101 drives the cleaning component 103 and the first filtering component 102 to perform a pulling movement together; in some embodiments, at least a part of the installation space and / or installation support of the cleaning component 103 may also be disposed outside the box body 101.

[0072] Wherein, the cleaning component 103 moving along the horizontal plane means that the moving direction of the cleaning component 103 is at least partially parallel to the horizontal plane. For example, the moving trajectory of the cleaning component 103 is completely parallel to the horizontal plane, or alternatively, the moving trajectory of the cleaning component 103 forms an angle with the horizontal plane, and this angle is less than 90° (the minimum included angle). The moving trajectory of the cleaning component 103 can be a straight line or a curve, but whether it is a straight line or a curve, its moving trajectory is at least partially parallel to the horizontal plane.

[0073] In the filtering device 10 of the embodiment of the present application, since the filtering device 10 is pulled and moved along the first horizontal direction, during the pulling process of the filtering device 10, it does not need to occupy the space above the clothing treatment device 1, reducing the requirement for the installation space of the clothing treatment device 1. In addition, the first filtering component 102 is cleaned by the cleaning component 103 during the movement process, so that impurities such as lint accumulated in the filtering device 10 are cleaned, improving the operation convenience of the user for cleaning the filtering device 10. Moreover, since the cleaning component 103 moves along the horizontal plane, the box body 101 does not need to reserve a movement space for the cleaning component 103 in the height direction. In this way, it is beneficial to reduce the size of the box body 101 in the height direction, thereby reducing the size of the filtering device 10 in the height direction, and further reducing the influence of the filtering device 10 on the size of the clothing treatment device 1 in the height direction.

[0074] Exemplarily, the first filtering component 102 is disposed in the accommodation space 101a, and divides the accommodation space 101a into a first sub-space 101a1 and a second sub-space 101a2. The first sub-space 101a1 is located upstream of the second sub-space 101a2 along the air flow direction. It can be understood that when the air flow passes through the accommodation space 101a, it first passes through the first filtering component 102 in the first sub-space 101a1 and then flows into the second sub-space 101a2. The first filtering component 102 intercepts impurities in the air flow, so that the impurity content in the air flow flowing into the second sub-space 101a2 is reduced.

[0075] In some embodiments, please refer to Figure 1, the cleaning component 103 is disposed in the first sub-space 101a1 and is used to clean the surface of the first filtering component 102 facing the side where the first sub-space 101a1 is located. It should be noted that when the air flow passes through the first filtering component 102, impurities are mainly intercepted on the surface of the first filtering component 102 facing the side where the first sub-space 101a1 is located. Therefore, the cleaning component 103 is disposed in the first sub-space 101a1, which can better clean the first filtering component 102.

[0076] Exemplarily, please refer to Figure 2 , the filtering device 10 further includes a driving mechanism 104, which is connected to the cleaning component 103 and is used to drive the cleaning component 103 to move, so that one end of the cleaning component 103 (hereinafter simply referred to as the cleaning end 103a) moves along the surface of the first filtering component 102 to realize the cleaning of the first filtering component 102.

[0077] It can be understood that after the impurities in the air flow passing through the first filtering component 102 are intercepted, some impurities are left on the side of the first filtering component 102 facing the first sub-space 101a1. During the process of the driving mechanism 104 driving the cleaning component 103 to move, the cleaning end 103a of the cleaning component 103 moves relative to the surface of the first filtering component 102 facing the first sub-space 101a1 to scrape and clean the accumulated impurities on the first filtering component 102.

[0078] Exemplarily, please refer to Figure 1 , when the driving mechanism 104 does not drive the cleaning component 103 to move, the cleaning end 103a of the cleaning component 103 rests on the first filtering component 102 and is located at the end far from the air inlet 101b. In this way, when the cleaning component 103 is not working, the obstruction of the cleaning component 103 to the air flow flowing from the air inlet 101b to the air outlet 101c can be reduced. In addition, during cleaning, the cleaning end 103a of the cleaning component 103 moves towards the direction close to the air inlet 101b, which is convenient for pushing and gathering the impurities towards the air inlet 101b and facilitating the pouring out of the gathered impurities from the air inlet 101b.

[0079] During cleaning, the number of movements of the cleaning component 103 is not limited, and the user can decide according to actual usage needs.

[0080] Exemplarily, the driving mechanism 104 is disposed on the box body 101. In this way, the box body 101 can provide installation support for the driving mechanism 104, which is beneficial to the modular design and modular manufacturing of the filtering device 10.

[0081] Exemplarily, the box body 101 can be a cuboid hollow structure. The box body 101 forms the outer shell of the filtering device 10, and the appearance shape of the box body 101 can be designed according to needs and is not limited herein.

[0082] In some embodiments, please refer to Figure 1 , the first filter component 102 includes a first support frame 1021 and a first filter screen 1022 disposed on the first support frame 1021. In this way, the first support frame 1021 can provide a supporting force for the first filter screen 1022, so that the first filter screen 1022 can maintain its filtering ability under the impact of the air flow.

[0083] Please refer to Figure 1 , the bottom wall and / or the top wall of the box body 101 has a positioning groove 101f adapted to the first support frame 1021. In this way, the positioning groove 101f enables the first support frame 1021 to be reliably installed in the box body 101, reducing the possibility of the first filter component 102 being deflected under the impact of the air flow and improving the reliability and stability of the first support frame 1021; in addition, during the assembly process, the positioning groove 101f facilitates the rapid positioning of the first filter component 102, improving the assembly efficiency.

[0084] It can be understood that the setting of the positioning groove 101f includes three methods: the first is that the bottom wall of the box body 101 has a positioning groove 101f adapted to the first support; the second is that the top wall of the box body 101 has a positioning groove 101f adapted to the first support frame 1021; the third is that both the bottom wall and the top wall of the box body 101 have positioning grooves 101f adapted to the first support frame 1021.

[0085] In some embodiments, please refer to Figure 2 , the filtering device 10 further includes a second filter component 105. Along the air flow direction, the second filter component 105 is disposed upstream of the air outlet 101c, or the second filter component 105 is disposed at the air outlet 101c. In this way, the air flow flowing out of the accommodation space 101a still needs to pass through the second filter component 105 before flowing out through the air outlet 101c, so that the air flow filtered by the first filter component 102 is filtered a second time by the second filter component 105, further improving the filtering effect of the filtering device 10.

[0086] Exemplarily, the second filter component 105 is detachably connected to the box body 101. In this way, it is convenient to detach the second filter component 105 from the box body 101, facilitating the replacement, cleaning, or maintenance of the second filter component 105.

[0087] The manner in which the second filter component 105 is detachably connected to the box body 101 is not limited. For example, screw connection, sliding connection, snap connection, etc. are not limited herein.

[0088] In some embodiments, the second filter component 105 is slidably connected to the cartridge 101 so that the second filter component 105 can be withdrawn from the cartridge 101 along the sliding direction. Herein, withdrawing from the cartridge 101 means that the second filter component 105 is completely separated from the cartridge 101. When cleaning is required, the second filter component 105 is withdrawn from the cartridge 101 along the sliding direction, and the second filter component 105 can be cleaned separately. After the cleaning is completed, the second filter component 105 is inserted into the cartridge 101. The operation is simple and convenient, improving the convenience for the user to clean the filtering device 10.

[0089] In some embodiments, please refer to Figure 5 , the filtering device 10 includes a handle assembly 106. The handle assembly 106 is disposed at the first end of the cartridge 101 along the first horizontal direction to pull the filtering device 10 along the first horizontal direction. In this way, when the filtering device 10 is installed in the air duct 13a, the filtering device 10 can be withdrawn from the air duct 13a along the first horizontal direction through the handle assembly 106.

[0090] Exemplarily, the second filter component 105 can be withdrawn from the second end of the cartridge 101 along the first horizontal direction. The handle assembly 106 does not interfere with the withdrawal action of the second filter component 105, and the two do not interfere with each other; and when the filtering device 10 is placed in the air duct 13a, the side where the handle assembly 106 is located is generally the appearance surface, and the extraction structure reserved by the cartridge 101 for the second filter component 105 does not affect the appearance of the filtering device 10; in addition, when the second filter component 105 is withdrawn from the cartridge 101, the user can hold the handle assembly 106, which is convenient for withdrawing the second filter component 105 from the cartridge 101. In addition, the cartridge 101 does not need to reserve a movement space for the second filter component 105 in the height direction. Thus, it is beneficial to reduce the size of the cartridge 101 in the height direction.

[0091] Exemplarily, the filtering device 10 further includes a trigger and a locking member disposed on the handle assembly 106. The locking member is connected to the trigger. The locking member is used to lock the filtering device 10 on the air duct 13a, and the trigger is used to drive the locking member to move between the unlocking position and the locking position under an external force. It can be understood that when the locking member is in the locking position, a restraining effect is generated between the filtering device 10 and the air duct 13a, restricting the relative movement between the filtering device 10 and the air duct 13a, so that the filtering device 10 is fixed on the air duct 13a at this time, reducing the influence of the airflow in the air duct 13a on the filtering device 10, and improving the safety and reliability.

[0092] Exemplarily, please refer to Figure 2, the second filtering component 105 includes a second support frame 1051 and a second filter screen 1052 connected to the second support frame 1051. The second support frame 1051 can provide a supporting force for the second filter screen 1052 so that the second filter screen 1052 can maintain its filtering ability under the impact of air flow.

[0093] Exemplarily, please refer to Figure 1 , the box body 101 has a guide rail groove 101d adapted to the second support frame 1051. The second support frame 1051 is arranged in the guide rail groove 101d. The guide rail groove 101d extends along the first horizontal direction and penetrates through the end face of the box body 101 to define a bayonet 101d1. The bayonet 101d1 is used for the second support frame 1051 to be drawn out to the outside of the guide rail groove 101d. The second filtering component 105 is drawn out from the second end of the box body 101 along the first horizontal direction through the guide rail groove 101d and the bayonet 101d1.

[0094] In some embodiments, please refer to Figure 1 , the air inlet 101b is arranged on the side wall of the second end of the box body 101 along the first horizontal direction, the air outlet 101c is arranged on the side wall of the first end of the box body 101 along the second horizontal direction, and the driving mechanism 104 is arranged on the side wall of the second end of the box body 101 along the second horizontal direction. Wherein, the first horizontal direction and the second horizontal direction intersect and are both perpendicular to the height direction of the box body 101.

[0095] It can be understood that the handle assembly 106 and the air inlet 101b are respectively arranged at both ends of the box body 101 along the first horizontal direction, and the driving mechanism 104 and the air outlet 101c are respectively arranged at both ends of the box body 101 along the second horizontal direction. Wherein, the first horizontal direction intersects with the second horizontal direction. It should be noted that the included angle between the first horizontal direction and the second horizontal direction is not limited, for example, a vertical or nearly vertical angle, such as 60° - 120°. In the embodiments of the present application, the first horizontal direction and the second horizontal direction are perpendicular as an example for description.

[0096] In some embodiments, please refer to Figure 5 , the filtering device 10 includes a sealing structure 107. The handle assembly 106 is arranged at the first end of the box body 101 along the first horizontal direction, the air inlet 101b is arranged on the side wall of the second end of the box body 101 along the first horizontal direction, and the sealing structure 107 is arranged outside the second end of the box body 101 and surrounds the air inlet 101b. The air inlet 101b and the handle assembly 106 are arranged at both ends of the box body 101 along the first horizontal direction, so that when the handle assembly 106 is pushed along the first horizontal direction, the docking effect between the air inlet 101b and the sealing structure 107 is enhanced, and the sealing performance of the sealing structure 107 is improved.

[0097] It can be understood that the filtering device 10 is installed after the air duct 13a, and the sealing structure 107 seals the gap between the filtering device 10 and the air duct 13a, improving the waterproof level at the connection between the filtering device 10 and the air duct 13a. For example, it can reach the waterproof level of IP65 (full name: Ingress Protection 65, which means complete dust protection and prevention of water spray intrusion). In some embodiments, please refer to Figure 1 , the first filtering component 102 is arc-shaped, and both the air inlet 101b and the cleaning component 103 are located on the concave side of the first filtering component 102. It can be understood that the arc shape of the first filtering component 102 increases the effective area of the first filtering component 102, improving the filtering area of the first filtering component 102 for the air flow. The air flow rate passing through the first filtering component 102 at the same time increases, improving the filtering efficiency of the first filtering component 102. In addition, during the rotation of the cleaning component 103, the rotation trajectory of the cleaning end 103a adapts to the arc contour of the first filtering component 102, facilitating the contact between the cleaning end 103a and the first filtering component 102.

[0098] It can be understood that the rotation axis of the cleaning component 103 is parallel to the height direction of the laundry treatment device 1.

[0099] The manner in which the driving mechanism 104 drives the cleaning component 103 is not limited. For example, in some embodiments, the driving mechanism 104 has a power source, such as a motor, and can be automatically driven without the need for the user to apply force. In other embodiments, the driving mechanism 104 is a non-powered mechanism, and the user needs to manually apply force to the driving mechanism 104 to force the driving mechanism 104 to move, and then drive the cleaning component 103 to move through the driving mechanism 104.

[0100] In some embodiments, please refer to Figure 2 , the driving mechanism 104 includes a force-applying member 1041 and a transmission component 1042. The transmission component 1042 connects the force-applying member 1041 and the cleaning component 103. The force-applying member 1041 is disposed outside the box body 101 and can move relative to the box body 101 under an external force, and drives the cleaning component 103 to rotate through the transmission component 1042. Among them, the external force can be the force applied by the user. It can be understood that by applying force to the force-applying member 1041 outside the box body 101, the transmission component 1042 drives the cleaning component 103 to rotate, which can save the space inside the box body 101, leaving space for more air flow to enter the box body 101, improving the filtering efficiency of the filtering device 10; in addition, it is also convenient for the user to hold the force-applying member 1041 and apply force to the force-applying member 1041.

[0101] The manner in which the force-applying member 1041 moves relative to the box body 101 is not limited. For example, it can be relative sliding, relative rotation, etc., and is not limited here.

[0102] In some embodiments, please refer to Figure 3 and Figure 4 , on the outer surface of the side wall of the box body 101 close to the force application member 1041, there is a recessed area 101g. The force application member 1041 has an initial position. In the initial position, the force application member 1041 is received in the recessed area 101g. It can be understood that when the force application member 1041 is in the initial position, the degree to which the force application member 1041 protrudes from the outer surface of the box body 101 can be reduced, or the force application member 1041 does not protrude from the outer surface of the box body 101, reducing the influence of the force application member 1041 on the external dimensions of the filtering device 10 and also reducing the influence of the force application member 1041 on the pulling movement of the filtering device 10.

[0103] Among them, the initial position refers to the position where the force application member 1041 is located when the filtering device 10 is in the air duct 13a.

[0104] In some embodiments, please refer to Figure 3 , an opening 1011 is provided on the side wall of the box body 101 close to the force application member 1041. It should be noted that in the embodiments where there is a recessed area 101g, the opening 1011 can be within the range of the recessed area 101g or outside the range of the recessed area 101g, and no limitation is made here.

[0105] Exemplarily, the opening 1011 communicates with the first sub-space 101a1. The opening 1011 is used for an external cleaning member to extend into the box body 101 to clean the inner wall of the box body 101 and / or the first filtering assembly 102.

[0106] In some embodiments, the force application member 1041 is also used to open or close the opening 1011.

[0107] It can be understood that when the filtering device 10 is filtering air flow, the force application member 1041 is in the position of closing the opening 1011, reducing the probability of the air flow flowing through the accommodation space 101a leaking from the opening 1011 and ensuring the ability of the filtering device 10 to filter impurities in the air flow.

[0108] For the filtering device 10 of this embodiment, after the filtering device 10 is pulled out from the air duct 13a, first move the force application member 1041 to the position of opening the opening 1011, and extend an external cleaning member into the accommodation space 101a through the opening 1011, so that the cleaning member can clean the first filtering assembly 102 and / or the side wall of the accommodation space 101a.

[0109] It should be noted that the external cleaning member can be a cleaning tool such as a brush.

[0110] In other embodiments, a separate sealing plug may also be provided for the opening 1011, and the sealing plug can pluggably close the opening 1011.

[0111] In some embodiments, please refer to Figure 2 , the first end of the force application member 1041 is the force application end 1041a, and the second end of the force application member 1041 is rotatably connected to the transmission assembly 1042. Therefore, the user can hold the force application end 1041a by hand, so that the force application member 1041 swings around its second end.

[0112] The transmission assembly 1042 is connected to the cleaning assembly 103. The force application member 1041 can rotate under the action of an external force, and drive the cleaning assembly 103 to rotate through the transmission assembly 1042. In this way, the cleaning of the first filter assembly 102 can be realized.

[0113] The specific structure of the transmission assembly 1042 is not limited, as long as it can transmit the power of the force application member 1041 to the cleaning assembly 103 and drive the cleaning assembly 103 to rotate.

[0114] In some embodiments, please refer to Figure 4 , the transmission assembly 1042 includes at least one gear 10421. A tooth structure 10411 is provided at the second end of the force application member 1041, and the tooth structure 10411 meshes with the gear 10421 of the transmission assembly 1042 for transmission. In this way, when the force application member 1041 moves under the action of an external force, the tooth structure 10411 drives the engaged gear 10421 to move, thereby driving the transmission assembly 1042 to move, and further driving the cleaning assembly 103 to move, starting the cleaning work of the first filter assembly 102. In this embodiment, through the meshing transmission of the tooth structure 10411 and the gear 10421, the transmission reliability and transmission efficiency are high, it is not easy to slip, and the failure rate is low. In this embodiment, when the user holds the force application end 1041a and drives the force application member 1041 to rotate, the force application member 1041 and the tooth structure 10411 are similar to a lever structure. The force application member 1041 has a relatively long force arm. The user applies a relatively small force to form a relatively large torque on the tooth structure 10411, so that the tooth structure 10411 can reliably drive the gear 10421 to rotate, which can save the user's physical strength.

[0115] In this embodiment, when the filtering device 10 is inserted into the air duct 13a, the inner wall of the air duct 13a will contact and press the force applying member 1041, so that the force applying end 1041a of the force applying member 1041 rotates towards the direction close to the box body 101 until the force applying end 1041a of the force applying member 1041 is close to the box body 101. In this way, the reset of the force applying member 1041 can be realized during the process of inserting the air duct 13a, and the force applying member 1041 can also be restricted to prevent the force applying member 1041 from shifting. That is to say, the air duct 13a does not need to be provided with a special structure to reset and restrict the force applying member 1041, which is beneficial to simplifying the structure of the air duct 13a. Exemplarily, the rotation axis of the cleaning assembly 103 is substantially parallel to the height direction of the box body 101.

[0116] Exemplarily, please refer to Figure 4 and Figure 6 , the cleaning assembly 103 has a rotating shaft mounting portion 1031, the gear 10421 is coaxially connected to the rotating shaft mounting portion 1031, the force applying member 1041 rotates around the axis of the tooth structure 10411, and the tooth structure 10411 meshes with the gear 10421. It can be understood that when the force applying member 1041 rotates around the tooth structure 10411, the tooth structure 10411 rotates accordingly to drive the meshing gear 10421 to rotate, and then the gear 10421 drives the cleaning assembly 103 to rotate around the axis of the rotating shaft mounting portion 1031, so as to realize the force applying member 1041 driving the cleaning assembly 103 to rotate, with high transmission efficiency and low failure rate.

[0117] It should be noted that the coaxial connection between the gear 10421 and the rotating shaft mounting portion 1031 can be a plug-in connection with a plug-and-play fit or a welding, and the present application does not limit this here.

[0118] Exemplarily, please refer to Figure 1 and Figure 4 , when the force applying member 1041 is in the initial position, the force applying end 1041a is located at the first end of the force applying member 1041 along the first horizontal direction, and the cleaning end 103a is located at one end of the first filtering assembly 102 away from the air inlet 101b of the box body 101. It can be understood that the air inlet 101b is located at the second end of the box body 101 along the first horizontal direction. That is to say, when the force applying member 1041 is in the initial position, the force applying end 1041a and the cleaning end 103a are close to each other, which can not only save the internal space of the filtering device 10, but also save the use space of the filtering device 10 in the laundry treatment device 1.

[0119] The cooperation between the tooth structure 10411 and the gear 10421 is used to make the force - applying end 1041a move away from the box body 101, so that the cleaning end 103a can move along the surface of the first filter assembly 102 towards the air inlet 101b of the box body 101. It can be understood that during the movement of the cleaning assembly 103 driven by the force - applying member 1041, the force - applying end 1041a and the cleaning end 103a move away from each other, which conforms to ergonomics. At the same time, the cleaning end 103a can also carry the impurities on the surface of the first filter assembly 102 towards the air inlet 101b, facilitating the removal of the impurities from the filter device 10 through the air inlet 101b.

[0120] In some other embodiments, please refer to Figure 6 , the tooth structure 10411 is configured as a rack structure and is arranged on the side of the force - applying member 1041 facing the transmission component 1042. The force - applying member 1041 is slidably connected to the box body 101 to move linearly under an external force, so as to drive the cleaning assembly 103 to rotate through the transmission component 1042. Configuring the tooth structure 10411 as a rack structure enables the force - applying member 1041 to be generally in a flat structure, facilitating the force - applying member 1041 to fit on the outer surface of the side wall of the box body 101, making the structure compact.

[0121] It can be understood that the tooth structure 10411 is configured as a rack structure and is arranged on the side of the force - applying member 1041 facing the transmission component 1042. When the force - applying member 1041 moves linearly under an external force, the tooth structure 10411 remains meshed with the gear 10421, converting the linear motion of the force - applying member 1041 into the rotation of the gear 10421, thereby driving the cleaning assembly 103 to rotate and realizing the cleaning of the first filter assembly 102.

[0122] Exemplarily, please refer to Figure 6 , there is a sliding groove 101e outside the second end of the box body 101 along the second horizontal direction. The sliding groove 101e extends along the first horizontal direction. The force - applying member 1041 makes a linear reciprocating movement along the sliding groove 101e under an external force. In this way, the sliding groove 101e restricts the movement track of the force - applying member 1041 under an external force, so that when the force - applying member 1041 moves linearly, it always maintains a connection relationship with the box body 101, thereby enabling the tooth structure 10411 and the gear 10421 to remain in a meshed state.

[0123] In some embodiments, please refer to Figure 6, the cleaning component 103 includes a rotating shaft mounting portion 1031, a skeleton 1032, and a brush head 1033. One end of the skeleton 1032 is connected to the rotating shaft mounting portion 1031, and the brush head 1033 is disposed at the end of the skeleton 1032 away from the rotating shaft mounting portion 1031. Among them, the brush head 1033 is used to contact the first filter component 102 to clean the first filter component 102. It should be noted that the rotating shaft mounting portion 1031 is connected to the transmission component 1042. Driven by the force-applying member 1041, the transmission component 1042 drives the rotating shaft mounting portion 1031 to rotate, so that the brush head 1033 moves relative to the first filter component 102, thereby cleaning the first filter component 102.

[0124] Exemplarily, the cabinet 12 has a front panel located on the front side of the cylinder assembly 11, and the front panel has a first opening 12a through which the filtering device 10 can be withdrawn from the cabinet 12. When the filtering device 10 is located on the airflow path of the air duct 13a, the handle assembly 106 covers the first opening 12a. At this time, the surface of the handle assembly 106 away from the side where the box body 101 is located serves as the appearance surface of the clothing treatment device 1.

[0125] In some embodiments, please refer to Figure 7 , the clothing treatment device 1 includes a detergent box 14, and the filtering device 10 is located above the detergent box 14. In this way, the arrangement of the filtering device 10 conforms to the user's usage habit, improving the user's usage experience.

[0126] In some embodiments, please refer to Figure 8 , the air duct 13a has a docking port 13a1. The air inlet 101b of the box body 101 is disposed on the rear side wall of the box body 101, and the rear side wall of the box body 101 is hermetically docked with the docking port 13a1 along the first horizontal direction. It should be noted that the rear side wall of the box body 101 refers to the end of the box body 101 away from the handle assembly 106 along the first horizontal direction. It can be understood that the air flow flows from the docking port 13a1 of the air duct 13a to the air inlet 101b and enters the filtering device 10 for filtering treatment. The hermetic docking of the rear side wall of the box body 101 and the docking port 13a1 in the front-rear direction reduces the leakage amount of the air flow during the process of flowing to the air inlet 101b.

[0127] In some embodiments, please refer to Figure 8, the air duct 13a has a transition cavity 13b, a first installation cavity 13c and a second installation cavity 13d. The filtering device 10 is arranged in the first installation cavity 13c. The laundry treatment device 1 includes an evaporator 15 and a condenser 16, and the evaporator 15 and the condenser 16 are arranged in the second installation cavity 13d. The transition cavity 13b is connected to the air outlet 101c. The filtering cavity is arranged at the rear side of the first installation cavity 13c, and the junction between the two defines a docking port 13a1. It can be understood that the air flow is filtered by the filtering device 10 and then flows to the evaporator 15 and the condenser 16, so that the amount of lint attached to the evaporator 15 and the condenser 16 is reduced, and the heat exchange effect between the air flow and the evaporator 15 and the condenser 16 is improved.

[0128] Exemplarily, the laundry treatment device 1 includes a base 13, and the space inside the base 13 defines a part of the air duct 13a.

[0129] Exemplarily, the base 13 is arranged above the cylindrical body assembly 11.

[0130] The various embodiments / implementations provided in this application can be combined with each other without contradiction.

[0131] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included in the protection scope of this application.
