The air distribution cavity includes an air distribution cavity main port and a plurality of air distribution cavity branch ports. External air can enter the air distribution cavity through the air distribution cavity main port. By controlling any one of the air distribution cavity branch ports to open, the air in the air distribution cavity can enter the corresponding drum through the air distribution cavity branch port respectively; or by controlling the opening of any one of the air distribution cavity branch ports, the air in the corresponding drum can enter the air distribution cavity through the air distribution cavity branch port, and the air in the air distribution cavity can be discharged through the air distribution cavity main port; thus, the drying requirements of different drums are met.

[0049] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0052] It should also be noted that the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such commodity or system.

[0053] In the prior art, for a multi-cylinder washing machine to achieve multi-cylinder washing and drying, the required drying system has a complex structure and a cumbersome control process; someone proposed a wind distribution housing, which forms a wind distribution cavity. By controlling the movement of the baffle, any branch port of the wind distribution cavity can be opened to connect the wind distribution cavity with the cylinder corresponding to the branch port of the wind distribution cavity to meet the drying requirements of different cylinders; however, the radial length of the wind distribution frame cannot be adjusted. When the baffle moves along with the wind distribution frame, there is friction between the seal and the side wall of the wind distribution housing, resulting in wear of the seal and reducing the sealing effect of the seal on the branch port of the wind distribution cavity;

[0054] The present invention creatively provides a wind distribution component. The wind distribution housing forms a main air duct, a main air outlet is formed at one axial end of the main air duct, and a plurality of branch air outlets are formed on the side wall of the main air duct; the wind distribution frame forms a first wind distribution frame structure and a second wind distribution frame structure, the first driving member forms a first driving member structure, and the second driving member forms a second driving member structure; the first wind distribution frame structure is drivingly connected to the first driving member structure, and the second wind distribution frame structure is drivingly connected to the second driving member structure; while the first driving member drives the wind distribution frame to rotate, the second driving member drives the wind distribution frame to slide radially along the main air duct, so that the baffle opens or closes any one of the branch air outlets; on the one hand, when the baffle seals the branch air outlet, the sealing effect can be improved; on the other hand, when the baffle opens the branch air outlet, the distance between the baffle and the side wall of the main air duct is increased, and the wear of the sealing member on the baffle is reduced.

[0055] Embodiment 1

[0056] <Wind distribution component>

[0057] As Figures 1a to 4b shown, this embodiment provides a wind distribution component for a laundry treatment device, especially a double-barrel washing machine with a drying function; the wind distribution component includes:

[0058] A wind distribution housing 2, which forms a main air duct 231, a main air outlet 241 is formed at one axial end of the main air duct 231, and a plurality of branch air outlets 242 are formed on the side wall of the main air duct 231; the main air outlet 241 and the branch air outlets 242 are both communicated with the main air duct 231; specifically, the wind distribution housing 2 includes a main housing 21 and a plurality of branch housings 22, the main housing 21 is in a cylindrical structure, and the plurality of branch housings 22 are arranged at intervals along the circumference of the main housing 21 outside the main air duct 231 and each branch housing 22 forms a branch air duct 232, and the plurality of branch air ducts 232 are in one-to-one correspondence and communication with the plurality of branch air outlets 242;

[0059] A wind distribution frame 31, which is rotatably arranged in the main air duct 231; the wind distribution frame 31 forms a first wind distribution frame structure 313 and a second wind distribution frame structure 314, and the first wind distribution frame structure 313 and the second wind distribution frame structure 314 are arranged at intervals in the radial direction of the main air duct 231; a baffle 32 is arranged on one side of the wind distribution frame 31 away from the center line of the main air duct 231; a sealing member 34 is arranged on one side of the baffle 32 close to the side wall of the main air duct 231; the sealing member 34 is made of rubber material and is nested on the baffle 32; specifically, the baffle 32 is in an arc shape, and the baffle 32 and the main air duct 231 are coaxially arranged; the baffle 32 can close one of the plurality of branch air outlets 242 and open the other branch air outlets 242 or open all the plurality of branch air outlets 242; when the branch air outlet 242 is opened, by controlling the movement of the first wind distribution frame 31, the baffle 32 moves with the second wind distribution frame, and the opening degree of the branch air outlet 242 can be adjusted;

[0060] The first driving member 41 and the second driving member 42, the first driving member 41 is formed with a first driving member structure 411, and the second driving member 42 is formed with a second driving member structure 421; both the first driving member structure 411 and the second driving member structure 421 are arranged in the main air duct 231; specifically, the second driving member 42 is detachably arranged on the main housing 21, and according to actual needs, the second driving member with the corresponding structure can be arranged on the main housing; among them, for the second driving members with different structures, the distance between the second driving member structure 421 and the center line of the main air duct 231 is different;

[0061] The first air distribution frame structure 313 is drivingly connected to the first driving member structure 411, so that the first driving member 41 can drive the air distribution frame 31 to rotate around the center line of the main air duct 231; the second air distribution frame structure 314 is drivingly connected to the second driving member structure 421, so that the second driving member 42 can drive the air distribution frame 31 to slide along the radial direction of the main air duct 231; the second driving member 42 can adjust the sliding distance of the air distribution frame 31 in the radial direction of the main air duct 231;

[0062] While the air distribution frame 31 rotates and slides, the baffle 32 moves away from the side wall of the main air duct 231, and the seal 34 can open any one of the branch air outlets 242, increasing the radial distance between the seal 34 and the side wall of the main air duct 231 and reducing the frictional loss between the seal 34 and the side wall of the main air duct 231; or the baffle 32 approaches the side wall of the main air duct 231, and the seal 34 can seal any one of the branch air outlets 242, increasing the degree of fit between the seal 34 and the side wall of the main air duct 231 and improving the sealing degree of the seal 34 for the branch air outlet 242;

[0063] The structure is simple and occupies little space; there are various ventilation modes, the ventilation volume can be adjusted, and different ventilation requirements can be met.

[0064] The following further describes the first air distribution frame structure 313 and the first driving member structure 411. The first air distribution frame structure 313 is a groove structure, and the first driving member structure 411 is a column structure; both the first air distribution frame structure 313 and the first driving member structure 411 extend along the radial direction of the main air duct 231, and the first driving member structure 411 is arranged inside the first air distribution frame structure 313;

[0065] The first air distribution frame structure 313 has a limiting effect on the first driving member structure 411 in the circumferential direction of the main air duct 231, so that the first driving member 41 can drive the air distribution frame 31 to rotate;

[0066] The first driving member structure 411 and the first air distribution frame structure 313 are in sliding fit in the radial direction of the main air duct 231, and thus the air distribution frame 31 can slide relative to the first driving member 41;

[0067] That is, when the first driving member 41 drives the first air distribution frame 31 to rotate, the first air distribution frame 31 can slide radially along the main air duct 231.

[0068] Furthermore, the cross-sections of both the first air distribution frame structure 313 and the first driving member structure 411 are waist-shaped.

[0069] The following further describes the second air distribution frame structure 314 and the second driving member structure 421. The second air distribution frame structure 314 is a column structure, and the second driving member structure 421 is a groove structure; along the extending direction of the second driving member structure 421, the second driving member structure 421 includes a proximal end and a distal end, and the radial distance between the proximal end and the center line of the main air duct 231 is less than the radial distance between the distal end and the center line of the main air duct 231; the second air distribution frame structure 314 can slide along the second driving member structure 421 between the proximal end and the distal end;

[0070] When the second air distribution frame structure 314 cooperates with the proximal end, the baffle 32 is close to the side wall of the main air duct 231; when the second air distribution frame structure 314 cooperates with the distal end, the baffle 32 is close to the center line of the main air duct 231; that is, when the second air distribution frame structure 314 cooperates from the proximal end to the distal end, the air distribution frame 31 can slide radially along the main air duct 231, making the baffle 32 gradually approach the center line of the main air duct 231; when the second air distribution frame structure 314 cooperates from the distal end to the proximal end, the air distribution frame 31 can slide radially along the main air duct 231, making the baffle 32 gradually approach the side wall of the main air duct 231;

[0071] The first air distribution frame structure 313 includes a first radial end and a second radial end in the radial direction of the main air duct 231. The first radial end and the second radial end are respectively located on both sides of the center line of the main air duct 231. The first radial end is located on the side close to the baffle 32, and the second radial end is located on the side far from the baffle 32;

[0072] The radial distance between the first radial end and the center line of the main air duct 231 and the radial distance between the distal end and the center line of the main air duct 231 determine the radial sliding range of the air distribution frame 31 and the maximum radial distance between the baffle 32 and the side wall of the main air duct 231; it is designed that the radial distance between the first radial end and the center line of the main air duct 231 is greater than the radial distance between the distal end and the center line of the main air duct 231 to increase the radial sliding range of the air distribution frame 31 and the maximum radial distance between the baffle 32 and the side wall of the main air duct 231 when the baffle 32 is far from the branch air outlet 242; thus, when the baffle 32 is far from the branch air outlet 242, the maximum radial distance between the baffle 32 and the side wall of the main air duct 231 is determined by the radial distance between the distal end and the center line of the main air duct 231; therefore, when the baffle 32 rotates, there will be no friction between the seal 34 and the side wall of the main air duct 231, which can reduce the wear of the seal 34 and reduce problems such as abnormal noise caused by friction;

[0073] The radial distance between the second radial end and the center line of the main air duct 231 and the radial distance between the short-range end and the center line of the main air duct 231 determine the radial sliding range of the air distribution frame 31 and the minimum radial distance between the baffle 32 and the side wall of the main air duct 231. It is designed that the radial distance between the second radial end and the center line of the main air duct 231 is greater than the radial distance between the short-range end and the center line of the main air duct 231, so as to increase the radial sliding range of the air distribution frame 31 and reduce the minimum radial distance between the baffle 32 and the side wall of the main air duct 231. In this way, when the baffle 32 approaches the branch air outlet 242, the minimum radial distance between the baffle 32 and the side wall of the main air duct 231 is determined by the radial distance between the short-range end and the center line of the main air duct 231. The seal 34 is in interference fit with the side wall of the main air duct 231, and can squeeze the branch air outlet 242 to achieve a sealing effect.

[0074] The second driving member 42 is detachably arranged in the main air duct 231, and the second driving member 42 with a suitable structure can be selected according to actual needs. When the structures of the second driving members 42 are different, the radial distances between the remote end and the center line of the main air duct 231 and between the short-range end and the center line of the main air duct 231 are different, so that the second driving member 42 can be applicable to different air distribution casings 2, increasing the applicable range.

[0075] Furthermore, the second driving member structure 421 is annular, that is, the second driving member structure 421 is an annular groove structure. The second driving member structure 421 is arranged around the outside of the first driving member structure 411. The second driving member structure 421 includes a convex arc section 422 and a concave arc section 423. The convex arc section 422 protrudes towards the center line of the main air duct 231, the concave arc section 423 is connected to the convex arc section 422, and the concave arc section 423 concaves towards the side wall of the main air duct 231.

[0076] The convex arc section 422 forms a short-range end, and the concave arc section 423 forms a remote end. When the second air distribution frame structure 314 slides along the convex arc section 422, it can cooperate with the short-range end, and when the second air distribution frame structure 314 slides along the concave arc section 423, it can cooperate with the remote end.

[0077] In some embodiments, both the convex arc section 422 and the concave arc section 423 are provided with a plurality of them. The plurality of convex arc sections 422 are arranged at intervals, and a concave arc section 423 is connected between two adjacent convex arc sections 422.

[0078] Each convex arc section 422 forms a plurality of short-range ends, and the distances between at least two of the plurality of short-range ends and the center line of the main air duct 231 are equal. When the second air distribution frame structure 314 cooperates with the two short-range ends, the degrees of sealing the branch air outlet 242 by the baffle 32 are relatively close.

[0079] Each concave arc segment 423 is formed with a plurality of remote ends, and the distances between at least two of the plurality of remote ends and the center line of the main air duct 231 are not equal; when the second air distribution frame structure 314 is matched with the two remote ends, the distances between the baffle 32 and the side wall of the main air duct 231 are different; in this way, the rotation space of the air distribution frame 31 is larger and it can be applicable to different seals 34.

[0080] Preferably, the second driving member 42 is an annular cam.
