[0054] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0055] The terms used in the embodiments of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The singular forms "a," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise. "A plurality" generally includes at least two, but does not exclude the inclusion of at least one.

[0056] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0057] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0058] In the prior art, a filter and a spray mechanism are provided in the air duct. The filter traps the hair in the air, and the spray mechanism cleans the hair trapped by the filter. However, the spray holes of the spray mechanism are fixed in position, and the spray coverage area is limited. Therefore, the hair removal is not comprehensive and thorough, the cleaning efficiency is low, a large amount of spray water is required, and new hair is easily accumulated.

[0059] The present invention creatively provides a lint cleaning device, in which a shaking mechanism is arranged on the outside of a frame, a sliding member is slidably arranged on a bracket, and a connecting member is connected between the sliding member and the frame; when the shaking mechanism is in a first working state, the sliding member slides in a direction away from the frame, and the connecting member stretches the frame; when the shaking mechanism is in a second working state, the sliding member slides in a direction close to the frame, and the connecting member compresses the frame; the frame alternately stretches and compresses to cause the filter to shake, thereby reducing the adhesion between the lint and the filter, breaking up the lint on the filter, and improving the efficiency of cleaning lint.

[0060] Example 1

[0061] like Figures 1 to 3 As shown, this embodiment provides a lint cleaning device for an air duct of a clothes processing device; the lint cleaning device is arranged in the air duct and includes:

[0062] The filter assembly includes a frame 11, a filter 12 and a bracket 13. The frame 11 is made of elastic material. When an external force acts on the frame 11, the frame 11 can undergo tensile deformation toward the outside of the frame 11 and compressive deformation toward the inside of the frame 11. The filter 12 is provided on the inside of the frame 11, and the bracket 13 is provided on the outside of the frame 11. The bracket 13 is used to be provided on the side wall of the air duct. When air flows through the air duct, the filter 12 can intercept hair in the air. There is a gap between the frame 11 and the side wall of the air duct, leaving space for the tensile deformation of the frame 11. The frame 11 is detachably mounted on the side wall of the air duct via the bracket 13, allowing the filter 12 to be replaced in a timely manner. A filter 12 of a corresponding filtration level can be provided according to actual filtering needs to effectively intercept debris in the air. Alternatively, multiple filters 12 of gradually decreasing filtration levels can be provided along the extending direction of the air duct according to actual filtering needs. This, on the one hand, expands the range of debris intercepted in the air, intercepting debris of different sizes to meet various interception needs; on the other hand, it extends the life of the filter 12, avoiding the problem of premature accumulation of a large amount of debris on the filter 12, which leads to a reduction in ventilation volume.

[0063] The de-tangling mechanism 2 includes a sliding member 21 and a connecting member 22. The sliding member 21 is slidably disposed on the bracket 13. The sliding direction of the sliding member 21 is consistent with the deformation (tension and compression) direction of the frame 11. The connecting member 22 is connected between the sliding member 21 and the frame 11. When the sliding member 21 slides, the connecting member 22 can drive the frame 11 to undergo tensile and compressive deformation. The de-tangling mechanism 2 has a first working state and a second working state.

[0064] When the shaking mechanism 2 is in the first working state, the sliding member 21 is controlled to slide relative to the bracket 13 in a direction away from the frame 11, and the connecting member 22 can stretch the frame 11 toward the outside of the frame 11, causing the frame 11 to be stretched and deformed toward the outside of the frame 11;

[0065] When the shaking mechanism 2 is in the second working state, when the sliding member 21 is controlled to slide relative to the bracket 13 toward the frame 11, the connecting member 22 can compress the frame 11 toward the inside of the frame 11, causing the frame 11 to be compressed and deformed toward the inside of the frame 11;

[0066] When the shaking mechanism 2 switches between the first working state and the second working state, the filter 12 can shake with the tensile deformation and compressive deformation of the frame 11, thereby reducing the adhesion between the filter 12 and the hair debris, which is conducive to the rapid separation of the hair debris and the filter 12, improving the cleaning efficiency of the filter 12, and solving the problem in the prior art that the adhesion between the hair debris and the filter 12 is large, resulting in difficulty in cleaning the hair debris on the filter 12, incomplete cleaning and low cleaning efficiency.

[0067] Furthermore, the connecting member 22 is made of an elastic material; preferably, the connecting member 22 is a spring; when the sliding member 21 is controlled to slide back and forth, the connecting member 22 can be periodically deformed, so that the frame 11 can be periodically stretched and compressed;

[0068] When the connecting member 22 stretches the frame 11 toward the outside of the frame 11 and the length of the connecting member 22 is greater than the original length of the connecting member 22 , the tensile force provided to the frame 11 by the connecting member 22 gradually increases, and the tensile deformation of the frame 11 gradually increases;

[0069] When the connecting member 22 compresses the frame 11 toward the inside of the frame 11 and the length of the connecting member 22 is less than the original length of the connecting member 22 , the compressive force provided to the frame 11 by the connecting member 22 gradually increases, and the compressive deformation of the frame 11 gradually increases;

[0070] This is beneficial to reducing the adhesion between the hair debris and the filter screen 12, allowing the hair debris to be quickly separated from the filter screen 12, thereby increasing the speed of cleaning the hair debris.

[0071] As mentioned above, the sliding member 21 can slide relative to the bracket 13. The structure for driving the sliding member 21 to slide affects the movement stability of the sliding member 21 and the space occupied by the shaking mechanism 2. The specific structure for driving the sliding member 21 to slide is further described below. The shaking mechanism 2 also includes a driving motor 23 and a screw rod 24. The driving motor 23 is arranged on the bracket 13 and is away from one end of the frame 11. One end of the screw rod 24 is drivingly connected to the output shaft of the driving motor 23, and the screw rod 24 and the sliding member 21 are connected by a threaded transmission. The driving motor 23 rotates the screw rod 24, and then the sliding member 21 can slide along the extension direction of the screw rod 24.

[0072] When the drive motor 23 is controlled to run alternately in forward and reverse directions, the slider 21 can slide back and forth under the action of the screw rod 24 , that is, the slider 21 slides away from the frame 11 or slides towards the frame 11 relative to the bracket 13 .

[0073] The deformation of the frame 11 is related to the number of the de-stacking mechanisms 2 and the coordination of the de-stacking mechanisms 2. The number and location of the de-stacking mechanisms 2 are further described below. Multiple brackets 13 and multiple de-stacking mechanisms 2 are provided, and the multiple brackets 13 are spaced apart around the frame 11. The multiple de-stacking mechanisms 2 and the multiple brackets 13 are provided in a one-to-one correspondence, and the sliding member 21 of each de-stacking mechanism 2 can be controlled to move independently.

[0074] When the sliding member 21 of each shaking mechanism 2 is controlled to move, the sliding members 21 of the plurality of shaking mechanisms 2 can slide in a coordinated manner to adjust the shaking direction and / or shaking size of the filter screen 12 .

[0075] Specifically, the air duct includes a heating air duct and a condensing air duct 5 connected to the heating air duct. The cross-section of the connecting point between the heating air duct and the condensing air duct 5 is circular, and the frame 11 is circular; the bracket 13 extends radially along the frame 11, and multiple brackets 13 are arranged at intervals along the circumference of the frame 11. The sliding member 21 of each shaking mechanism 2 can be controlled to slide radially along the frame 11.

[0076] Preferably, there are four brackets 13 and four shaking mechanisms 2, and the four brackets 13 are respectively a first bracket, a second bracket, a third bracket and a fourth bracket, and the first bracket, the second bracket, the third bracket and the fourth bracket are arranged on the outside of the frame 11 in a counterclockwise direction; the first bracket is located on the right side of the center line of the frame 11, the second bracket is located on the upper side of the center line of the frame 11, the third bracket is located on the left side of the center line of the frame 11, and the fourth bracket is located on the lower side of the center line of the frame 11; the four shaking mechanisms 2 are respectively a first shaking mechanism, a second shaking mechanism, a third shaking mechanism and a fourth shaking mechanism; the sliding member 21 of the first shaking mechanism is slidably provided on the first bracket, the sliding member 21 of the second shaking mechanism is slidably provided on the second bracket, the sliding member 21 of the third shaking mechanism is slidably provided on the third bracket, and the sliding member 21 of the fourth shaking mechanism is slidably provided on the fourth bracket;

[0077] When the sliding member 21 of the second and fourth loosening mechanisms slide away from the frame 11, and the sliding member 21 of the first and third loosening mechanisms slide toward the frame 11, the frame 11 may undergo tensile deformation in the vertical direction and compressive deformation in the horizontal direction.

[0078] When the sliding member 21 of the first and third shaking mechanisms slide away from the frame 11, and the sliding member 21 of the second and fourth shaking mechanisms slide toward the frame 11, the frame 11 may undergo tensile deformation in the left-right direction and compressive deformation in the up-down direction.

[0079] Example 2

[0080] Based on Example 1, this example proposes that Figure 4 As shown, the frame 11 is formed with a water outlet 111 downstream of the filter screen 12. The water outlet 111 faces the inner side of the frame 11 and can spray water toward the filter screen 12.

[0081] There are multiple water outlet holes 111, and the multiple water outlet holes 111 are arranged at intervals around the frame 11; specifically, the multiple water outlet holes 111 are evenly spaced along the circumference of the frame 11;

[0082] When water is input into the water outlet 111 , the water outlet 111 sprays water toward the filter screen 12 , thereby cleaning the hair debris on the filter screen 12 .

[0083] The trajectory of the water sprayed from the water outlet 111 affects the coverage area of ​​the water flow. In this embodiment, the trajectory of the water sprayed from the water outlet 111 is designed to be arc-shaped and convex toward the downstream of the filter 12; that is, the water flows first toward the downstream of the filter 12 and then toward the filter 12. In this way, by adjusting the speed of the water sprayed from the water outlet 111, the coverage area of ​​the water sprayed from the water outlet 111 can be adjusted, thereby comprehensively and thoroughly cleaning the filter 12 from the debris.

[0084] In other embodiments, the water outlet end of the water outlet 111 is provided with a movable water-guiding structure; by controlling the movement of the water-guiding structure, the movement trajectory of the water flow sprayed from the water outlet 111 can be adjusted; in this way, the water flow sprayed from the water outlet 111 can cover the filter 12, thereby achieving comprehensive and thorough cleaning of the filter 12 on the hair debris; specifically, the water-guiding structure is a water-guiding plate, which can swing along the upstream and downstream directions of the filter 12; by adjusting the swinging angle of the water-guiding plate, the water flow sprayed from the water outlet 111 can flow to different positions of the filter 12, and then the water flow can cover the entire area of ​​the filter 12.

[0085] The size of the water outlet 111 affects the flow rate of the water sprayed by the water outlet 111. From the outside to the inside of the frame 11, the center line of the water outlet 111 gradually moves away from the filter 12, and the flow area of ​​the water outlet 111 gradually decreases; when the water flows through the water outlet 111, the flow velocity increases, which can increase the coverage area of ​​the water flow, which is conducive to comprehensively and thoroughly cleaning the filter 12 on the hair debris.

[0086] Example 3

[0087] Based on Example 1, this example proposes that Figures 5a to 5d As shown, the lint cleaning device further includes a spray arm assembly, which includes a main spray arm 31, a main shaft 32, an auxiliary spray arm 33 and a secondary shaft 34. The main spray arm 31 is rotatably arranged in the air duct through the main shaft 32, and the auxiliary spray arm 33 is rotatably arranged on the main spray arm 31 through the secondary shaft 34.

[0088] A main shaft cavity is formed inside the main shaft 32, and a main spray cavity 312 communicating with the main shaft cavity is formed inside the main spray arm 31. A main spray hole 311 is formed on the side wall of the main spray arm 31, communicating with the main spray hole 311 and the main spray cavity 312. The main spray hole 311 faces the filter 12 and can spray water onto the filter 12. Specifically, the main spray arm 31 is formed with a plurality of main spray holes 311 spaced apart along the extension direction of the main spray arm 31. When the main shaft cavity delivers water to the main spray cavity 312, the water in the main spray cavity 312 can be sprayed out through the plurality of main spray holes 311, thereby washing away the debris on the filter 12.

[0089] A secondary shaft cavity is formed inside the secondary shaft 34, and a secondary spray cavity is formed inside the secondary spray arm 33. The main spray cavity 312, the secondary shaft cavity, and the secondary spray cavity are sequentially connected. A secondary spray hole 331 is formed on the side wall of the secondary spray arm 33, and the secondary spray hole 331 is connected to the secondary spray cavity. The secondary spray hole 331 faces the filter 12 and can spray water onto the filter 12. Specifically, the secondary spray arm 33 is formed with a plurality of secondary spray holes 331 spaced apart along the extension direction of the secondary spray arm 33. When the main spray cavity 312 transports water to the secondary spray cavity, the water in the secondary spray cavity can be sprayed out through the plurality of secondary spray holes 331, thereby washing away the debris on the filter 12.

[0090] When the main shaft 32 and the auxiliary shaft 34 are controlled to rotate, the main spray arm 31 and the auxiliary spray arm 33 can spray and flush the filter screen 12;

[0091] Specifically, the main spray arm 31, the main shaft 32, the auxiliary spray arm 33 and the auxiliary shaft 34 are all linear structures. The extension direction of the main shaft 32 is parallel to the extension direction of the auxiliary shaft 34. The axis of the main shaft 32 is collinear with the center line of the frame 11. The extension direction of the main spray arm 31 is consistent with the diameter direction of the frame 11. The extension direction of the main spray arm 31 is parallel to the extension direction of the auxiliary spray arm 33. The extension length of the main spray arm 31 is less than the extension length of the auxiliary spray arm 33.

[0092] Furthermore, a movable main valve core 35 is provided at the main spray hole 311. The main valve core 35 can slide along the depth direction of the main spray hole 311 and / or rotate along the first direction. When the water in the main spray chamber 312 flows through the main spray hole 311, the main valve core 35 moves, and the position of the main valve core 35 relative to the main spray hole 311 changes, thereby adjusting the spraying effect of the water flow. Specifically, the flow direction, flow rate or flow rate of the water flow can be adjusted to achieve spraying effects of different angles and different intensities. The first direction is perpendicular to the depth direction of the main spray hole 311; and / or,

[0093] A movable auxiliary valve core is provided at the auxiliary spray hole 331, and the auxiliary valve core can slide along the hole depth direction of the auxiliary spray hole 331 and / or rotate along the second direction; when the water in the auxiliary spray hole 331 flows through the auxiliary spray hole 331, the auxiliary valve core moves, and the position of the auxiliary valve core relative to the auxiliary spray hole 331 changes, which can adjust the spraying effect of the water flow; specifically, the flow direction, flow velocity or flow rate of the water flow can be adjusted to achieve spraying effects of different angles and different intensities; wherein, the second direction is perpendicular to the hole depth direction of the auxiliary spray hole 331.
