[0025] like Figures 1 to 5 As shown, the cleaning machine of this embodiment includes a water tank 1, a door body 2 and a switch assembly 3. The rear edge of the door body 2 is rotatably connected to the rear edge of the top opening of the water tank 1. A sink groove 121 is provided on the periphery of the top opening of the water tank 1. When the door is closed, the door body 2 is located in the sink groove 121, and the rear edge of the door body 2 can be rotatably constrained in the sink groove 121.

[0026] In this embodiment, the switch assembly 3 can be movably arranged on the door body 2. When the door is closed, the rear part of the switch assembly 3 covers the gap 21 formed between the rear edge of the door body 2 and the rear side wall of the sink groove 121.

[0027] Specifically, the switch assembly 3 is accommodated in the door body 2, and the top of the switch assembly 3 is covered with a panel 32. The area of ​​the panel 32 is larger than the area of ​​the switch assembly body. From a top view, the front edge of the panel 32 is located in front of the front side wall of the switch assembly 3, the rear edge of the panel 32 is located behind the rear side wall of the switch assembly 3, and the side edge of the panel 32 is located outside the side edge of the switch assembly 3. In the closed state, the rear side wall of the switch assembly 3 is arranged close to the rear inner wall of the door body 2, and the rear edge of the panel 32 extends to the rear side of the door body 2 and covers the gap 21. With the above structure, the gap is covered by the panel.

[0028] The door body 2 has an open top receiving groove 22 at the rear, and the edge of the receiving groove 22 extends upward to form a mounting edge 23 higher than the upper surface of the front portion of the door body 2. The switch assembly 3 is arranged in the receiving groove 22 so as to be movable forward and backward, and the panel 32 is movable forward and backward and covers the mounting edge 23. The above structure is adopted to eliminate the resistance to the movement of the panel 32, so that the panel 32 can move smoothly and maintain a beautiful appearance.

[0029] In this embodiment, the switch assembly 3 is arranged at the rear edge of the door body 2, which can avoid accidental touching of the switch key and improve the user experience. At the same time, the switch assembly 3 of this embodiment can adaptively move forward and backward with the opening and closing of the door body 2. It moves backward in the closed state to cover the gap 21 to prevent debris from entering and bacteria from growing, and moves forward in the switched state to avoid interference between the panel 32 and the sink groove 121, greatly improving the user experience.

[0030] This embodiment is provided with a driving structure 4 that can move the switch assembly 3 forward and backward, and the driving structure 4 is connected to the side of the switch assembly 3 through a screw drive mechanism 4. The above structure facilitates the adaptive movement of the switch assembly with the door opening and closing action.

[0031] Specifically, the driving mechanism 4 includes an elastic member 41, a screw rod 42, a driving block 43 and a driving member 44. The elastic member 41 keeps the switch assembly 3 always moving forward. The screw rod 42 is rotatably disposed transversely in front of the switch assembly 3. The driving block 43 is disposed on the screw rod 42 so as to reciprocate along the screw rod 42. The driving block 42 applies or cancels the backward thrust to the switch assembly 3 as it reciprocates. The driving member 44 is disposed at the end of the screw rod 42 and is used to drive the screw rod 42 to rotate. The above structure is adopted to drive the switch assembly 3 to move forward and backward.

[0032] The side of the switch assembly 3 is provided with a limit block 031, and the elastic member 41 is a spring, which is provided on the side of the switch assembly 3 and has its front end abutting against the limit block 031 and its rear end abutting against the inner side wall of the rear edge of the door body 2. This structure enables the switch assembly 3 to automatically move forward when the thrust on the switch assembly 3 is canceled, avoiding interference during the switching process.

[0033] The bottom of the switch assembly 3 is provided with a convex catch 032 arranged near the front edge, and correspondingly, the driving block 43 is formed with a guide inclined surface 431 that can cooperate with the convex catch 032 during the movement of the driving block 43 toward the convex catch 032, thereby driving the switch assembly 3 to move backward. With the above structure, when the driving block 42 moves toward the midpoint of the screw rod 42, it can gradually touch the convex catch 032 and push the switch assembly 3 backward through the convex catch 032. When the driving block 43 moves toward the end of the screw rod 42, it can gradually cancel the contact with the convex catch 032, thereby canceling the backward thrust on the switch assembly 3, facilitating the switch assembly 3 to move forward under the action of the elastic member 41, thereby eliminating switch interference.

[0034] In this embodiment, there are two drive blocks 43, which are arranged corresponding to the two sides of the switch assembly 3 respectively. The guide slope 431 gradually tilts outward and backward from the switch assembly 3. The door body 2 is also provided with a micro switch 45 located beside the switch assembly 3 and can be triggered by the drive block 43 when the drive block 43 completely cancels the thrust on the switch assembly 3. Two sets of drive blocks 43 are provided, and the drive can be realized by a screw rod 42, and the force applied to the switch assembly 3 can be balanced, so that the switch assembly 3 can move forward and backward stably and reliably. When the micro switch 45 is triggered, it can be used to accurately determine whether the thrust on the switch assembly 3 is completely canceled.

[0035] The driving member 44 is a motor disposed at the end of the screw rod 42, and the output shaft of the motor 44 is connected to the end of the screw rod 42 through a gear 441. This structure is more convenient for controlling the rotation speed of the screw rod 42, improving the accuracy of the backward movement of the switch assembly 3, so that the gap can be covered without causing friction and collision problems caused by the transition of the switch assembly 3.

[0036] The water tank 1 of this embodiment includes a first water tank 11 and a second water tank 12 arranged side by side, and the door body 2 is arranged on the top of the second water tank 12. A groove 111 is formed at the top opening of the first water tank 11, which is connected with the sink groove 121 of the second water tank 12. A decoration 112 is arranged at the rear of the groove 111. In the closed state, the rear edge of the decoration 112 is substantially flush with the rear edge of the panel 32. The above structure can prevent the overflow of accumulated water on the one hand, and improve the exquisiteness of the product appearance on the other hand.

[0037] The upper surface of at least the front portion of the door body 2 forms a water guide slope 20, which is gradually inclined downward from the side edge of the second water tank 12 away from the first water tank 11 toward the first water tank 11. With such a structure, it is convenient to drain the accumulated water on the upper surface of the door body 2 into the adjacent water tank in time, so that the door body has the function of draining water after washing items.

[0038] When the door is closed, the switch assembly 3 is located at the rear edge of the door body 2, and the rear part of the switch assembly 3 covers the gap 21 formed between the rear edge of the door body 2 and the rear side wall of the countersunk groove 121; when opening the door, the user presses the door opening button on the switch assembly 3, and the switch assembly 3 starts to move forward. After the switch assembly 3 moves forward a set distance, it remains so that the rear edge of the switch assembly 3 does not interfere with the countersunk groove 121; when closing the door, the user flips the door body 2 downward and presses the door body 2. When the door body 2 is fully closed, the switch assembly 3 starts to move backward until the rear part of the switch assembly 3 covers the gap 21 formed between the rear edge of the door body 2 and the rear side wall of the countersunk groove 121, and remains there.
