Specific implementation

[0027] The utility model concepts of the present disclosure will be described below using terms generally used by those skilled in the art to convey the substance of their work to other skilled artisans in the art. However, these utility model concepts can be embodied in many different forms, and therefore should not be considered limited to the embodiments described herein.

[0028] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0029] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0030] In order to solve the problem that the lint in the prior art can block the filter screen 3, resulting in a decrease in the drying efficiency of the clothes treatment device, the present embodiment proposes a drying air duct self-cleaning structure, as shown in the accompanying drawings. Figures 1-6 The drying air duct self-cleaning structure includes an air duct piece 2 and a water distribution plate 4. The air duct piece 2 has an air duct cavity 23 therein. The filter screen 3 is arranged in the air duct cavity 23. The water inlet 41 of the water distribution plate 4 is in communication with an external water supply device. At least the water outlet 42 of the water distribution plate 4 is arranged above the filter screen 3.

[0031] Therefore, by arranging the water distribution plate 4 at the air duct cavity 23 and arranging the water outlet 42 of the water distribution plate 4 above the filter screen 3, the external water can be introduced into the air duct cavity 23 through the water distribution plate 4 and flush the filter screen 3, which can effectively reduce the lint attached to the filter screen 3 and avoid the lint blocking the filter screen 3, resulting in a decrease in the drying air volume, and is conducive to ensuring that the clothes treatment device always has good drying efficiency.

[0032] The external water supply device can be a common faucet in daily life or a water storage device such as a water tank. Since the laundry treatment device often has a main water inlet system for supplying washing water to the washing tub, the water inlet 41 of the water distribution plate 4 can be connected to the main water inlet system of the laundry treatment device, and correspondingly, the water inlet 41 of the water distribution plate 4 can share an inlet valve with the main water inlet system of the laundry treatment device, or a separate inlet valve can be provided on the pipeline connected to the water inlet 41 of the water distribution plate 4 to independently control the water supply at the water distribution plate 4.

[0033] The water distribution plate 4 can be arranged entirely in the air duct cavity 23 and connected to the pipeline outside the air duct cavity 23 only through the water inlet 41; or the water distribution plate 4 can be arranged entirely outside the air duct cavity 23, with the water outlet 42 extending into the air duct cavity 23 and arranged above the filter screen 3.

[0034] The filter screen 3 is arranged horizontally or obliquely in the air duct cavity 23. Preferably, the included angle between the water flow sprayed by the water distribution plate 4 towards the filter screen 3 and the filter screen 3 is 30°-90°, so that the water flow can be sprayed more uniformly on the filter screen 3, and under the action of gravity, the lint on the filter screen 3 is washed to some extent, thereby improving the cleaning efficiency of the self-cleaning structure of the drying air duct.

[0035] The self-cleaning structure of the drying air duct includes a tub 1, one end of the air duct cavity 23 is in communication with a tub cavity 11 of the tub 1, and the other end is in communication with an air outlet 22 of the air duct 2, so that the hot air in the tub can carry water vapor out of the tub to realize drying of the clothes in the tub. Specifically, the tub 1 is provided with an air inlet 21, so that the tub cavity 11 can be in communication with the air duct cavity 23 through the air inlet 21.

[0036] The air duct 2 can be a component independent of the tub 1, or a structural component belonging to the tub 1. Preferably, the tub 1 and the air duct 2 are integrally formed. Correspondingly, the air duct 2 is located on the outer side of the tub 1, and the air duct cavity 23 in the air duct 2 extends upward as a whole. It should be noted that for the tub 1 structure of the prior art in the form of inner and outer tubs, the tub 1 of the present application is an outer tub.

[0037] The upper end of the barrel body 1 is provided with a cover plate 5, which is the same as the conventional outer barrel assembly. On this basis, in order to simplify the structure, simplify the assembly, and avoid the interference between the cover plate 5 and the air duct piece 2, the entire air duct piece 2 is divided into two parts in the application, specifically: the air duct piece 2 includes an air cavity part 24 and an air outlet part 25, the air cavity part 24 is connected with the outer wall of the barrel body 1 as a whole (integrally formed), the air outlet part 25 is connected with the cover plate 5 as a whole (integrally formed), and the air cavity part 24 and the air outlet part 25 are connected through a sealing structure. Therefore, the application does not need to additionally provide an independent air duct piece 2, and the assembly of the entire air duct piece 2 can be completed at the same time as the assembly of the barrel body 1 and the cover plate 5, which not only reduces the number of parts and the complexity of the structure and assembly, but also eliminates the interference problem between the cover plate 5 and the independent air duct piece 2.

[0038] Correspondingly, the air cavity part 24 and the air outlet part 25 are in communication and jointly form an air duct cavity 23; along the flow direction of the gas in the air duct cavity 23, the inlet of the air cavity part 24 corresponds to the air inlet 21, and the outlet of the air outlet part 25 corresponds to the air outlet 22.

[0039] For the sealing between the air cavity part 24 and the air outlet part 25, the upper end surface 241 of the air cavity part 24 is provided with a first sealing piece, and the lower end surface of the air outlet part 25 is provided with a second sealing piece, and the first sealing piece and the second sealing piece are connected to form a sealing structure, for example: the first sealing piece and the second sealing piece are sealing butt groove structures, and preferably, a sealing ring can be further provided to further improve the sealing effect.

[0040] For the split structure of the air duct piece 2, the water distribution plate 4 has a mounting part that can be lapped on the upper end surface 241 of the air cavity part 24. During assembly, the water distribution plate 4 can be pre-assembled on the upper end surface 241 of the air cavity part 24, and then the barrel body 1 and the cover plate 5 are assembled at the same time, and the air outlet part 25 and the upper end surface 241 of the air cavity part 24 will automatically form a limit to the water distribution plate 4, so that the water distribution plate 4 does not need to be assembled and fixed separately, which is beneficial to simplify the assembly operation of related parts. Specifically, the water distribution plate 4 is provided with a first mounting part 43, a second mounting part 44 and a third mounting part 45, so that the water distribution plate 4 can be stably mounted on the upper end surface 241 of the air cavity part 24.

[0041] For the assembly of the barrel body 1 and the cover plate 5, the barrel body 1 is provided with a first clamping piece 12 and a first fixing piece 13, the cover plate 5 is provided with a second clamping piece 51 and a second fixing piece 52, the first clamping piece 12 and the second clamping piece 51 are clamped, and the first fixing piece 13 and the second fixing piece 52 are connected through fasteners.

[0042] In the present application, for any clothes treatment device with drying function, the drying air duct self-cleaning structure described in the present embodiment can be included, and on the basis of the related structure and assembly relationship provided in the present embodiment, the clothes treatment device also includes conventional components such as a shell, a motor and the like; since they are all prior art, they will not be described here.

[0043] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
