[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 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 axial direction. 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 the first air duct 10 which enters the axial direction of the air guide port 31. The cover plate 4 is rotated to be in an open state relative to the air guide port 31 to constrain the second air duct 20 which extends radially and obliquely along the air guide port 31.

[0025] The cover plate 4 is formed by partially missing a sector plate at the inner end, and the outer edge of the cover plate 4 forms an arc edge 41 matching the edge of the air guide port 31, and the inner edges of the cover plates 4 jointly enclose a first air duct 10 for exposing the central part of the air guide port 31. With the above structure, when the cover plate 4 is closed, the air inlet direction is controlled to be concentrated and straight, so as to achieve rapid renewal of the airflow in the washing chamber.

[0026] The inner edge of the cover plate 4 is rotated and constrained in the air guide port 31. When 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, a second air duct 20 is enclosed between the arc-shaped edge 41 of each cover plate 4 and the edge of the air guide port 31. With the above structure, when the cover plate 4 is opened, the air inlet direction is controlled to be multi-directionally diffused, so that the drying range covers the return water area, filter plate, spray arm, etc. at the bottom of the box body in addition to the bowl basket, eliminating cleaning dead corners and improving the drying effect.

[0027] When the second air duct 20 is formed, the back of the cover plate 4 forms an air guide surface 43 for guiding the air body obliquely along the radial direction of the air guide port 31 into the box body 1. With the above structure, the air body is obliquely guided into a large area, which is conducive to eliminating the drying dead corner.

[0028] In order to facilitate the assembly of the cover plate 4, a partition rib 32 for separating the air 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 a hexagonal opening 321 is formed in the central part of the hexagonal structure. The cover plate 4 is composed of three pieces, and the inner edge of 4 is a straight edge 42. The partition rib 32 corresponding to the edge of the opening 321 is provided with an axis groove 322 arranged at intervals, and a rotating shaft 421 that can be rotatably connected to the corresponding axis groove 322 is provided at the straight edge 42 of the cover plate 4. The above structure facilitates the rotatable connection of the cover plate 4, and the connection is hidden at the partition rib, so the assembly is reliable and reasonable.

[0029] The cleaning machine of this embodiment also includes a driving structure 5 that can drive the cover plate 4 to rotate. The driving structure 5 is arranged corresponding to the central part of the air guide port 31 and is linked to the inner edge of the cover plate 4. Such a structure is adopted to control the air intake direction according to user needs. The driving structure 5 includes an elastic member 51 and a pressure plate 52. The elastic member 51 is a spring, which is arranged on the back of the cover plate 4 and makes the cover plate 4 always maintain a tendency to tilt relative to the air guide port 31. The pressure plate 52 can be reciprocated along the axial direction of the air guide port 31 and is located in the box body 1 and abuts against each cover plate 4. The above structure is adopted to facilitate the rotation control of the cover plate by moving the pressure plate 52 forward and backward in combination with the elastic force of the elastic member 51.

[0030] The central part of the air guide 31 is provided with an axial hole 311 which penetrates in the axial direction, and correspondingly, the back of the pressing plate 52 is provided with a threaded column 521 which is threadedly connected to the axial hole. The adjustment of the air inlet direction can be achieved by manually twisting the pressing plate before washing according to the amount of tableware placed in the bowl basket. For example, when there are many tableware placed in the bowl basket, the inclination of the second air duct 20 can be adjusted to the maximum to allow the incoming air to spread quickly and dry a large area; when the tableware placed in the bowl basket is small, the inclination of the second air duct 20 can be slightly reduced to shorten the travel of the incoming air to the bowl basket, thereby further improving the drying efficiency.

[0031] In this embodiment, the drying assembly 2 includes an air duct 21, a fan 22 and a heating element 23. The air duct 21 is provided on the outer wall of the box body 1 and surrounds the air inlet cover 3. The heating element 23 is provided in the air duct 21 and is used to heat the intake air. The fan 22 is provided in the air duct 21 and is located upstream of the heating element 23 to provide air supply power. The above structure is convenient for providing hot air for drying dishes and improving the drying effect.

[0032] In this embodiment, three rotatable cover plates 4 are provided at the air inlet cover 3. The cover plate 4 is rotated to cover the air guide port 31 to constrain a first air duct 10 for axial air intake along the air guide port 31. The cover plate 4 is rotated to be open relative to the air guide port 31 to constrain a second air duct 20 extending radially and obliquely along the air guide port 31. When the washing machine needs to be dried after washing, it can be adjusted to the second air duct 20 forming state, with a large air intake area and dispersed air intake direction, which is conducive to eliminating drying dead corners and improving drying efficiency. When the washing machine is not used for a long time, it can be adjusted to the first air duct 10 forming state, with concentrated air intake, which is only used to keep the washing chamber dry to avoid bacterial growth.
