The switch assembly is arranged on the door body. The switch assembly includes a switch module and a panel covering the upper surface of the switch module. The switch module is built into the door body and arranged near the rear edge of the door body. The panel constitutes a part of the upper surface of the door body.

[0008] The utility model configures the switch component as a switch module part and a panel part. The switch module is arranged in the door body and close to the rear edge. The switch module is covered by the panel to constitute a part of the upper surface of the door body, thereby realizing the rear placement of the switch component with a large distance from the human body, which can effectively avoid accidental touching of the switch key and improve the user experience.

[0009] Preferably, a sink groove is provided at the outer periphery of the top opening of the water tank, and when the door is closed, the door body is located in the sink groove, and the rear edge of the door body can be rotatably constrained in the sink groove. With such a structure, it is convenient to install the door body, and water stains on the top edge of the door body can enter the water tank through the sink groove.

[0010] As an improvement, when the door is closed, a gap is formed between the rear edge of the door body and the rear side wall of the sink trough, and the switch assembly can be arranged on the door body so as to move forward and backward and cover at least part of the gap when the door is closed. For a sink dishwasher that adopts a sink-type door body, it is inevitable that there will be a gap between the rear edge of the door body and the sink trough when the door is closed. The existence of this gap is not only unsightly, but also difficult to clean if small and broken things enter the gap. Since there is often accumulated water in the sink trough, problems such as mold and bacterial growth will occur over time, seriously affecting the user experience. In order to solve the above problems, the utility model places the switch assembly at the rear and arranges it into a structure that can move forward and backward. When the door is closed, the panel of the switch assembly moves backward to cover the gap.

In this embodiment, the switch assembly 3 is configured as a switch module part and a panel part. The switch module 31 is arranged in the door body 2 and arranged near the rear edge. The switch module 31 is covered by the panel 32 to constitute a part of the upper surface of the door body 2, thereby realizing the rear placement of the switch assembly 3, which is at a greater distance from the human body, can effectively avoid accidental touch of the switch key, and improve the user experience.

[0032] A sink groove 121 is arranged at the outer periphery of the top opening of the water tank. 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. With such a structure, it is convenient to install the door body 2, and water stains on the top edge of the door body 2 can enter the water tank through the sink groove 121.

[0033] In the closed state, a gap 21 is formed between the rear edge of the door body 2 and the rear side wall of the sink groove 121, and the switch assembly 3 can be arranged on the door body 2 so as to move forward and backward and cover at least part of the gap 21 in the closed state. For a sink dishwasher that adopts a sink-type installation of the door body 2, it is inevitable that there will be a gap 21 between the rear edge of the door body 2 and the sink groove 121 in the closed state. The existence of the gap 21 is not only unsightly, but also difficult to clean if small things enter the gap 21. Since there is often water accumulation in the sink groove 121, it will cause mold and breed bacteria over a long period of time, seriously affecting the user experience. In order to solve the above problems, the switch assembly 3 is rear-placed in this embodiment and is set to a structure that can move forward and backward. When the door is closed, the panel 32 of the switch assembly 3 moves backward to cover the gap 21. When the door is opened, the panel 32 moves forward a certain distance with the switch assembly 3 to avoid interference between the panel 32 and the sink groove 121 during the door opening process.

[0034] The rear part of the door body 2 is provided with a receiving groove 23 with an open top, and the edge of the receiving groove 23 extends upward to form an assembly edge 24 higher than the upper surface of the front part of the door body 2. The switch module 31 is arranged in the receiving groove 23 so as to be movable forward and backward, and the panel 32 is covered on the assembly edge 24 so as to be movable forward and backward. The above structure is adopted to facilitate the movement of the switch assembly 3 forward and backward, and during the movement of the panel 32, the appearance does not change much and remains relatively consistent. The receiving groove 23 of the door body 2 is provided with an assembly groove 22 arranged close to its rear edge, and the rear part of the switch module 31 is arranged in the assembly groove 22 so as to be movable forward and backward. This structure can guide the switch module 31 and improve the reliability and stability of the forward and backward movement of the switch assembly 3.

[0035] The cleaning machine of this embodiment further includes a driving structure 4 capable of moving the switch assembly 3 forward and backward, and the driving structure 4 is connected between the switch module 32, the door body 2 and the top opening of the second water tank 12, and is used to drive the switch assembly 3 to move forward as the door body 2 is opened, and to drive the switch assembly 3 to move backward as the door body 2 is closed. With the above structure, when the door is closed, the panel 32 of the switch assembly 3 moves backward to cover the gap 21, and when the door is opened, the panel 32 moves forward a certain distance with the switch assembly 3 to avoid interference between the panel 32 and the sink tank 121 during the door opening process.

[0036] The driving structure 4 includes an elastic member 41, a guide wheel 42 and a pull rope 43. The elastic member 41 is a spring, which is arranged in the door body 2. The first end of the spring abuts against the front side wall of the switch module 31, and the second end abuts against the front side wall of the accommodating groove 23, so that the switch assembly 3 always maintains a tendency to move backward. The guide wheel 42 is arranged near the front edge of the switch module 31. The first end of the pull rope 43 is connected to the outer end wall of the switch module 31. The pull rope 43 bypasses the guide wheel 42 and its second end is constrained in the sink groove 121. With the above structure, when closing the door, the elastic member 41 presses the switch module 31 to move it backward, thereby covering the gap 21; when opening the door, the pull rope 43 pulls the switch module 31 forward, and the switch assembly 3 overcomes the elastic force of the elastic member 41 and moves forward.

[0037] The rotation center of the door body 2 is A, and the rotation center of the second end of the pull rope 43 is B. B is located in front of A and is arranged lower than A. The rotation center of the guide wheel 42 is C, and the rotation center of the first end of the pull rope 43 is D. The distance between B and C is L1, and the distance between C and D is L2. During the door opening process, L1 gradually increases and L2 gradually decreases; during the door closing process, L1 gradually decreases and L2 gradually increases.

[0039] In this embodiment, when the door is closed, the distance between the rear edge of the panel 32 and the rear edge of the sink groove 121 is less than or equal to 1.2 mm. This structure ensures that the gap is small enough to prevent debris from entering and maintains beauty.

[0040] The door body 2 is arranged on the top of the second water tank 12, and 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. When the door is closed, the decoration 112 is substantially flush with 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.

[0041] The upper surface of the front part of the door body 2 forms a water guide slope 27, 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.
