[0032] The rotary disc 3 can rotate relative to the mounting member 2 about a horizontal axis. The peripheral edge of the rotary disc 3 is close to the inner wall surface of the mounting member 2 with a small gap. This reduces the air leakage from the gap between the rotary disc 3 and the mounting member 2, and does not affect the rotation of the rotary disc 3.

[0033] In this embodiment, the rotary disc 3 rotates under the reaction force of the air sprayed from the nozzles 31. Of course, the rotary disc 3 can also be driven to rotate by a driving mechanism such as a motor.

There are at least two groups of nozzles which are arranged along the radial direction of the rotation axis of the rotary disc 3. In this way, the air sprayed from the nozzles 31 generates a thrust force along the circumferential direction of the rotary disc 3. All the nozzles 31 initially spray air along the same rotational direction (clockwise or counterclockwise) of the circumferential direction of the rotary disc 3, so as to provide sufficient force to push the rotary disc 3.

[0035] The inner wall surface of the first side wall 21 is provided with a plurality of flow guide ribs 23. Each flow guide rib 23 extends along the radial direction of the air inlet 22. The flow guide ribs 23 are radially distributed around the air inlet 22. The projection of the nozzles 31 in the horizontal direction falls between two adjacent flow guide ribs 23. The flow guide ribs 23 guide the air to the nozzles 31 so that the air is sprayed from the nozzles 31.

[0036] It is to be noted that the projection of each nozzle 31 falls between two adjacent flow guide ribs 23.

[0037] The central part of the air inlet 22 is provided with a mounting shaft 24 which extends along the left-right direction. The mounting shaft 24 is connected to the wall surface of the air inlet 22 by a rib 25. The rotary disc 3 is rotatably mounted on the mounting shaft 24, i.e. the mounting shaft 24 is the rotation axis of the rotary disc 3.

[0038] In order to reduce the rotating friction of the rotary disc 3, a mounting groove 32 is arranged on the wall surface of the rotary disc 3 which is away from the washing cavity 11, a bearing 33 is arranged in the mounting groove 32, and the mounting shaft 24 passes through the bearing 33. The bearing 33 adopts the existing structure, and the cooperation among the bearing 33, the rotary disc 3 and the mounting shaft 24 also adopts the existing technology.

[0039] The fan 4 is also rotatably mounted on the mounting shaft 24, and the bearing 33 is located at the inner side of the fan 4, i.e. the side close to the washing cavity 11.
