[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5 As shown, the cleaning machine of this embodiment includes a box body 1 and a drying component 2. The side wall of the box body 1 is provided with an air inlet 11 and an air outlet 12. The drying component 2 is arranged outside the box body 1 and the output end is locked and connected to the air inlet 11 through an air inlet cover 3. The air inlet cover 3 is provided with an air guide port 31 which passes through the air axially. At least two rotatable cover plates 4 are arranged at the air inlet cover 3. The cover plate 4 is rotated to cover the air guide port 31 to constrain a first air guide area 10 which intakes air axially from the air guide port 31. The cover plate 4 is rotated to an inclined arrangement state relative to the air guide port 31 to constrain a second air guide area 20 which intakes air axially from the air guide port 31 and diffusely from the edge of the air guide port 31. The area of ​​the second air guide area 20 is larger than that of the first air guide area 10.

[0027] The cover plate 4 is formed by a fan-shaped plate partially missing at the inner end, and the outer edge of the cover plate 4 forms an arc-shaped edge 41 that matches the edge of the air guide port 31. The inner edges of each cover plate 4 jointly enclose a first air guide area 10 for exposing the central part of the air guide port 31. The above structure is adopted to achieve the control of the minimum air volume when the cover plate is closed. The inner edge of the cover plate 4 is rotationally constrained in the air guide port 31, and the cover plate 4 is rotated to a state where its arc-shaped edge 41 is tilted toward the box body 1 relative to the edge of the air guide port 31, and the second air guide area 20 is enclosed between the inner edges of each cover plate 4 and between the arc-shaped edge of each cover plate 4 and the edge of the air guide port 31. The above structure is adopted to achieve the control of the maximum air volume when the cover plate 4 is open, and the wind body is introduced in layers to eliminate the drying dead corners.

[0028] The central part of the second air guide area 20 forms a straight air duct 201, the edge part of the second air guide area 20 forms an inclined air duct 202, and the cover plate 4 forms an air guide surface for guiding the wind body along the radial direction of the air guide port 31 and obliquely into the box body 1. With the above structure, the wind body is introduced in layers, which is conducive to eliminating the drying dead corner.

[0029] In this embodiment, the cover plate 4 is composed of three pieces, and the arcuate edges 41 of the three cover plates 4 are spliced ​​together to form a circular structure that matches the edge of the air guide port 31. The inner edges of the three cover plates 4 are straight edges 42, and the straight edges 42 together enclose an air guide area with a triangular structure. The above structure is used to achieve the control of the minimum air volume.

[0030] In order to facilitate the assembly of the cover plate 4, a partition rib 32 for separating the wind body is provided in the air guide port 31, and the inner edge of the cover plate 4 is rotatably connected to the partition rib 32. The partition rib 32 encloses a hexagonal structure, and the central part of the hexagonal structure forms a hexagonal air outlet 321, and the central part of the second air guide area 20 is arranged corresponding to the air outlet 321. The partition rib 32 corresponding to the edge of the air outlet 321 is provided with spaced shaft grooves 322, and the straight edge 42 of the cover plate 4 is provided with a rotating shaft 421 that can be rotatably connected to the corresponding shaft groove 322. The above structure facilitates the rotatable connection of the cover plate 4, and the connection is hidden at the partition rib 32, so the assembly is reliable and reasonable.

[0031] When each cover plate 4 covers the air guide port 31, the straight sides 42 of each cover plate 4 together enclose a triangular air guide area corresponding to the three corners of the hexagonal air outlet 321 and its periphery. The above structure is used to achieve minimum air volume control.

[0032] The cleaning machine of this embodiment further includes a driving structure 5 capable of driving the cover plate 4 to rotate, the driving structure 5 being arranged corresponding to the central part of the air guide port 31 and being linked to the inner edge of the cover plate 4. Such a structure is adopted so as to control the air intake volume and air intake angle according to user needs.

[0033] The driving structure 5 includes an elastic member 51 and a driving member 52. The elastic member 51 is a spring. Each cover plate 4 is provided with a spring at its back. The rear end of the spring abuts against the partition rib 32. The spring keeps the cover plate 4 always inclined relative to the air guide port 31. The driving member 52 is a motor having an output shaft 521 extending along the central part of the air guide port 31 and reciprocating in the circumferential direction. The end of the output shaft 521 is connected to a pressing plate 53 that can abut against the side of each cover plate 4 located in the box body 1 and the abutment position is close to the inner edge of the cover plate 4. The above structure facilitates the rotation control of the cover plate by moving the pressing plate 53 forward and backward in coordination with the elastic force of the elastic member.

[0034] The back of the pressure plate 53 is provided with a guide sleeve 531 extending outward from the box body 1. Correspondingly, the central part of the air guide port 31 is provided with a guide hole 311 for the guide sleeve 531 to pass through and guide and cooperate with it. The output shaft 521 is connected to the guide sleeve 531. The end of the guide sleeve 531 is provided with a clamping foot 532 that can be relatively clamped with the outer edge of the guide hole 311. The output shaft 521 extends into the guide sleeve 531 and rotates with its thread. With the above structure, the adjustment of the air intake volume can be judged by the motor stall signal through the cooperation between 53 and the cover plate 4, and the cooperation between the clamping foot 532 and the end of the guide sleeve 531.

[0035] In this embodiment, three rotatable cover plates 4 are provided at the air inlet cover 3. When the cover plate 4 is rotated to cover the air guide port 31, a first air guide area 10 is constrained to intake air axially along the air guide port 31. When the cover plate 4 is rotated to be arranged obliquely relative to the air guide port 31, a second air guide area 20 is constrained to intake air axially and diffusely along the edge of the air guide port 31. When the washing machine needs to be dried after washing, it can be adjusted to the second air guide area 20 state with a large air intake volume to improve the drying efficiency. When the washing machine is in the state of storing tableware, it can be adjusted to the first air guide area 10 state with a small air intake volume, which is only used to keep the washing chamber dry to avoid bacterial growth, so as to reduce the user's usage cost.
