[0038] The following embodiments illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific embodiments of the present invention or making equivalent replacements for some technical features without departing from the spirit of the present invention scheme shall all be covered within the scope of the technical solution claimed by the present invention.

[0039] Please refer to Figures 1-10 , the present invention provides a filter cleaning structure for a dishwasher. The filter 2 is installed in the cup cavity 30 of the water cup 3 of the dishwasher. The filter cleaning structure includes a breather 44 and a spray cleaning assembly 1. The spray cleaning assembly 1 includes a water ring 11 and a water inlet part 15 provided on the water ring 11. The water ring 11 is sleeved outside the filter 2 of the dishwasher. A water cavity 10 is formed inside the water ring 11. One end of the water inlet part 15 is communicated with the water cavity 10, and the other end is communicated with the breather 44. The breather 44 is communicated with the water supply structure of the dishwasher. Spray holes are formed on the inner side of the water ring 11 and are opened towards the filter 2. The spray holes are communicated with the water cavity 10. In this way, the water supply structure of the dishwasher can supply water to the water cavity 10 through the breather 44, and the water in the water cavity 10 can flow out from the spray holes into the filter 2 to clean the filter 2, with a simple structure.

[0040] Optionally, the water ring 11 is sleeved on the upper part outside the filter 2. The spray holes include first spray holes 121 formed on the inner side of the water ring 11 and second spray holes 122 formed on the lower side of the water ring 11. In this way, the water flow can spray the filter 2 from top to bottom, finally fall to the bottom of the water cup 3, and then be discharged into the sewer outside the dishwasher, avoiding secondary pollution of the filter 2 by the sewage located at the bottom of the water cup 3.

[0041] Optionally, the upper hole wall of the first spray hole 121 is inclined upward from outside to inside, and the lower hole wall of the first spray hole 121 is inclined downward from outside to inside, so that the water sprayed out through the first spray hole 121 can be sprayed onto the upper part of the filter 2 along the upper and lower directions, ensuring the cleaning range of the upper part of the filter 2.

[0042] Optionally, the second spray hole 122 is arranged to incline downward and inward, so that the water ejected through the second spray hole 122 can be sprayed downward to the lower part of the filter 2, ensuring the cleaning range of the lower part of the filter 2.

[0043] Optionally, the spray assembly 1 further includes a sealing ring 14. The water ring 11 includes an upper ring body 111 and a lower ring body 112. The upper ring body 111 and the lower ring body 112 are covered to form a water cavity 10. The sealing ring 14 is arranged between the upper ring body 111 and the lower ring body 112 to prevent the water in the water cavity 10 from overflowing through the gap between the upper ring body 111 and the lower ring body 112.

[0044] Optionally, the spray assembly 1 further includes a buckle structure 13. The upper ring body 111 and the lower ring body 112 are buckled through the buckle structure 13, with a simple structure and easy installation. Of course, in other embodiments, the upper ring body 111 and the lower ring body 112 can also be connected by a threaded connection.

[0045] Optionally, the buckle structure 13 includes a clamping groove and a buckle body. The clamping groove is arranged on one of the upper ring body 111 and the lower ring body 112, and the buckle body is arranged on the other of the upper ring body 111 and the lower ring body 112. The buckle body is snapped into the clamping groove, thereby realizing the connection between the upper ring body 111 and the lower ring body 112.

[0046] Optionally, it further includes a cleaning water pump 43 and a cleaning water pipe 42. The first end of the cleaning water pipe 42 is connected to the water supply structure, the second end of the cleaning water pipe 42 is connected to the water inlet part 15, and the cleaning water pump 43 is installed on the cleaning water pipe 42. By setting the cleaning pump, the water in the water supply structure can be ejected into the filter 2 from the first spray hole 121 and the second spray hole 122 at a higher speed, thereby improving the cleaning effect.

[0047] Optionally, the breather 44 includes a breather body 441, a regenerated water cavity 10 arranged in the breather body 441, and a water outlet part 442 arranged on the breather body 441 and communicating with the regenerated water cavity 10. A water receiving port for connecting to the water supply pipe outside the dishwasher is arranged on the breather body 441. The water outlet part 442 includes a first water outlet port 4421 and a second water outlet port 4422. The first water outlet port 4421 is connected to the salt cavity of the dishwasher, and the second water outlet port 4422 is connected to the first end of the cleaning water pipe 42. Utilizing the water storage function of the breather 44 originally provided in the dishwasher, clean cleaning water is provided for the cleaning structure of the filter 2 without affecting the water supply to the salt cavity of the dishwasher, ensuring the cleaning effect and with a simple structure.

[0048] Optionally, a water inlet valve 41 is further arranged between the water receiving port and the water supply pipe outside the dishwasher.

[0049] On the other hand, the present utility model provides a dishwasher, which includes a water cup 3 and a filter 2 disposed in the cup cavity 30 of the water cup 3, and further includes the filter 2 cleaning structure of the above-mentioned dishwasher.

[0050] Optionally, it further includes a drainage structure, which includes a drainage pipe 51 and a drainage pump 52 installed on the drainage pipe 51. One end of the drainage pipe 51 communicates with the cup cavity 30, and the other end of the drainage pipe 51 communicates with a sewer outside the dishwasher to drain away the sewage after cleaning the filter 2 and the sewage after cleaning the tableware. The structure is simple.

[0051] Optionally, it further includes a dishwashing pipeline 62 and a water softener 61. One end of the dishwashing pipeline 62 is connected to the cup cavity 30 of the water cup 3, and the other end is connected to the water softener 61. The water softener 61 is connected to the respirator 44. The water in the respirator 44 is softened by the water softener 61 and then enters the water cup 3 through the dishwashing pipeline 62 to provide dishwashing water for the dishwasher.

[0052] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can be made, and these all belong to the protection scope of the present utility model.
