[0031] The following embodiments are used to illustrate the present utility model, but the present utility model is not limited by these embodiments. Modifying the specific embodiments of the present utility model or making equivalent replacements for some technical features without departing from the spirit of the present utility model scheme shall all be covered within the scope of the technical solution claimed by the present utility model.

[0032] Embodiment 1

[0033] Please refer to Figures 1-6, the present utility model provides a water storage tank structure for a dishwasher, including a water tank structure 1 and a water pipe 4. The water tank structure 1 includes a water tank body 11, a water inlet part 12, a ventilation part 13, a water outlet part 15, a limiting channel 14, and a float 31. The water tank body 11 is connected to a water cup 2 through the water inlet part 12. The water inlet part 12 and the ventilation part 13 are both arranged at the upper end of the water tank body 11. The ventilation part 13 is connected to the atmosphere outside the water tank body 11. The water outlet part 15 is arranged at the bottom of the water tank body 11. The limiting channel 14 is arranged vertically in the cavity of the water tank body 11. The upper end of the limiting channel 14 is connected to the water inlet part 12, and the lower end of the limiting channel 14 is connected to the cavity. The float 31 is arranged in the limiting channel 14 and can move along the limiting channel 14. The float 31 can float on the water surface of the cavity and rise and fall with the water surface of the cavity to block and open the water inlet part 12. The upper end of the water pipe 4 is connected to the water cup 2, and the lower end is connected to the water inlet part 12.

[0034] The water storage tank structure of the dishwasher provided by the present utility model stores the water flowing out of the water cup 2 by setting the water tank body 11. The water in the water cup 2 can continuously flow into the water tank body 11 until the float 31 rises with the water surface in the cavity and blocks the water inlet part 12, so that when the water in the water tank body 11 is transported to the steam generator of the dishwasher through the water outlet part, there is enough water stored in the water tank body 11 to avoid water shortage in the water tank body 11, thus preventing the steam generator of the dishwasher from dry burning. The structure is simple.

[0035] Optionally, a water pump is arranged between the water cup 2 and the water tank body 11. The water in the water cup 2 is pumped into the water tank body 11 by the water pump.

[0036] Optionally, it further includes a water pipe 4. The water tank body 11 is arranged below the water cup 2. The upper end of the water pipe 4 is connected to the water cup 2, and the lower end is connected to the water inlet part 12. By arranging the water tank body 11 below the water cup 2 of the dishwasher, there is a height difference H between the water tank body 11 and the water cup 2, so that when the water in the water tank body 11 is pumped to the steam generator of the dishwasher through the water outlet part 15 by the water pump, the water in the water cup 2 can continuously flow into the water tank body 11 through the water pipe 4 until the float 31 rises with the water surface in the cavity and blocks the water inlet part 12, thereby realizing timely water replenishment for the water tank body 11, avoiding water shortage in the water tank body 11, and preventing the steam generator of the dishwasher from dry burning. The structure is simpler and the cost is lower.

[0037] Optionally, the water tank body 11 further includes a partition 16 disposed in the cavity. The partition 16 is disposed horizontally and divides the cavity into an upper cavity 200 and a lower cavity 100. A water passing hole 160 is provided on the partition 16. The water passing hole 160 communicates the upper cavity 200 and the lower cavity 100. The upper end of the limiting channel 14 communicates with the water passing hole 160. The float 31 can float on the water surface of the cavity and rise and fall with the water surface of the cavity to block and open the water passing hole 160. When the lower cavity 100 is full of water, the float 31 blocks the water passing hole 160, and the water in the water cup 2 continues to flow into the upper cavity 200. The water in the upper cavity 200 plays a role in preventing the water in the lower cavity 100 from being polluted.

[0038] Optionally, the partition 16 is inclined and the water passing hole 160 is located at the lowest position of the partition 16, so as to facilitate the water in the upper cavity 200 to flow into the lower cavity 100 through the water passing hole 160.

[0039] Optionally, the water passing hole 160 is located directly below the water inlet part 12. A plug 32 is further provided at the upper end of the float 31. When the float 31 blocks the water passing hole 160, the plug 32 blocks the water inlet part 12. When the float 31 opens the water passing hole 160, the plug 32 opens the water inlet part 12. In this way, it can also prevent the water in the upper cavity 200 from flowing out through the ventilation part 13.

[0040] Optionally, the limiting channel 14 is formed by enclosing two adjacent side plates of the water tank body 11 with two enclosing plates. There is a water outlet gap between the enclosing plates and the bottom plate of the water tank body 11, and the structure is simple.

[0041] Embodiment 2

[0042] Please refer to Figure 7 , and Figure 8 , the difference between Embodiment 2 and Embodiment 1 is that the water passing hole 160 does not need to be located directly below the water inlet part 12, and the plug 32 does not need to be provided at the upper end of the float 31. In addition, it further includes an air pipe (not shown in the figure). The upper end of the air pipe is disposed higher than the water inlet end of the water pipe 4, and the lower end of the air pipe communicates with the ventilation part 13 to prevent the water in the upper cavity 200 from flowing out through the air pipe.

[0043] Optionally, the upper end of the air pipe communicates with the washing cavity of the dishwasher so that the pressure at the water inlet part 12 is the same as the pressure at the air inlet end.

[0044] On the other hand, the present utility model provides a dishwasher, including a water cup 2 and the water storage tank structure 1 of the above-mentioned dishwasher.

[0045] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
