[0031] A first water level sensor 5 and a second water level sensor 6 are provided in the dishwasher body 1. It should be noted that the first water level sensor 5 and the second water level sensor 6 are connected to the controller in the dishwasher body 1 through a wire 7. This is a prior art and will not be described in detail here. By providing the first water level sensor 5 and the second water level sensor 6, the water level inside the dishwasher body 1 can be monitored, so that the water level inside the dishwasher body 1 is between the first water level sensor 5 and the second water level sensor 6.

[0032] The water level control component is arranged on the dishwasher body 1, the first water level sensor 5 and the second water level sensor 6. The water level control component comprises a vertical displacement block 4, a screw rod 9 and a threaded barrel 11. The first water level sensor 5 and the second water level sensor 6 are both fixedly mounted on the vertical displacement block 4. It should be noted that the first water level sensor 5 and the second water level sensor 6 are driven to move vertically by the vertical displacement block 4, so that the positions of the first water level sensor 5 and the second water level sensor 6 can be regulated. When the number of dishes to be washed is small and not very dirty, the first water level sensor 5 and the second water level sensor 6 can be regulated downward, which can save water resources and avoid excessive waste of water resources; when the number of dishes to be washed is large and relatively dirty, the first water level sensor 5 and the second water level sensor 6 can be regulated upward to ensure the cleaning effect.

[0033] A through hole 10 is formed at the top of the vertical moving block 4 , a screw rod 9 is fixedly installed inside the dishwasher body 1 , a threaded barrel 11 is threadedly installed on the outside of the screw rod 9 , and an end of the threaded barrel 11 abuts against the vertical moving block 4 .

[0034] Through the above structure, when the first water level sensor 5 and the second water level sensor 6 need to be adjusted downward, the lower threaded barrel 11 is first rotated to move the lower threaded barrel 11 downward, and then the vertical movement block 4 automatically moves downward due to gravity, and then the upper threaded barrel 11 is rotated, and the vertical movement block 4 is tightened and limited by the two threaded barrels 11; when the first water level sensor 5 and the second water level sensor 6 need to be adjusted upward, the upper threaded barrel 11 is first rotated to move the upper threaded barrel 11 upward, and then the vertical movement block 4 is moved upward, and then the lower threaded barrel 11 is rotated, and the vertical movement block 4 is tightened and limited by the two threaded barrels 11, which makes the adjustment more convenient.

[0035] Example 2

[0036] In order to avoid the influence of the wire when regulating the water level sensor, the water level control assembly also includes a sealing pad 15 and two guide rods 3, the guide rod 3 is fixedly installed inside the dishwasher body 1, and the vertical movement block 4 is slidably sleeved on the outside of the two guide rods 3. A wire storage cavity 8 is opened on the side of the dishwasher body 1, and the first water level sensor 5 and the second water level sensor 6 are both connected with a wire 7, and the wire 7 is located in the wire storage cavity 8. It should be noted that in this way, the loose wire 7 can be stored in the wire storage cavity 8, and the wire 7 will not affect the movement of the vertical movement block 4. The line hole is arranged in advance on the dishwasher body 1, and the wire 7 is connected to the controller in the dishwasher body 1 through the pre-arranged line hole;

[0037] The sealing gasket 15 is installed on the vertical moving block 4, and the vertical moving block 4 is in sealing contact with the side wall of the dishwasher body 1 through the sealing gasket 15. Through the above structure, the sealing between the vertical moving block 4 and the side wall of the dishwasher body 1 can be ensured, and a certain water blocking effect can be achieved.

[0038] Specifically, a concave chamber is formed on the side of the vertical moving block 4 facing the wire storage chamber 8, and the wire 7 and other components can be accommodated in the chamber. The vertical moving block 4 can be sealed corresponding to the outer periphery of the inner chamber by the sealing gasket 15, and fit with the bottom surface of the storage chamber 8 to form a basically sealed state, thereby being able to roughly play a waterproof role and prevent water from directly impacting the inside. In addition, waterproof glue or other waterproof parts can be applied to the connection of the wire 7 to make it suitable for use in the environment inside the dishwasher.

[0039] In addition, the dishwasher in this embodiment may adopt a sink-type structure or a cabinet-type structure. If a sink-type structure is adopted, water can be directly stored in the sink; if a cabinet-type structure is adopted, it is necessary to ensure the sealing between the sealed door body and the dishwasher body, and multiple sealing structures may be provided to seal the connection between the two.
