[0053] Specifically, the filtering mechanism 1 has a basically cylindrical structure, after the washing water and impurities are filtered by the filtering mechanism 1, some small impurities will adhere to the filter screen 11 of the filtering mechanism 1, if the user forgets to clean the filter screen 11 regularly, the filter screen 11 will be blocked by the small impurities for a long time, which affects the filtering efficiency of the filtering mechanism 1. When the dishwasher in the present application executes the program of cleaning tableware, the self-cleaning of the filter screen 11 can be realized through the cooperation of the driving mechanism 3 and the cleaning mechanism 2, so as to avoid the situation that the small residues adhered to the filter screen 11 are not easy to be cleaned by the user, which affects the user experience.

[0054] Preferably, the dishwasher comprises a sprayer 4, the sprayer 4 is connected with the driving mechanism 3, and the driving mechanism 3 drives the sprayer 4 to be rotatably arranged in the tank. That is, the washing water is sprayed to the tableware to be washed in the tank through the rotation of the sprayer 4, so as to clean the tableware to be washed.

[0056] Further, when the water flows out through the spraying flow channel of the lower spraying arm, the spraying holes 44 of the upper spraying arm and the inside of the spraying support, the spraying arm 41 is driven to rotate on the spraying support, preferably, the driving direction of the driving mechanism 3 for driving the sprayer 4 to rotate is consistent with the driving direction of the water for driving the spraying arm 41 to rotate, further enhancing the impact force of the washing water, being able to more effectively flush the stains on the surface of the tableware, improving the cleaning effect of the washing water and improving the use experience of the user.

[0057] Further, the driving mechanism 3 can drive the sprayer 4 and the cleaning mechanism 2 to rotate simultaneously or at different times, in order to improve the overall cleaning efficiency of the dishwasher, the driving mechanism 3 in the application drives the sprayer 4 and the cleaning mechanism 2 to rotate simultaneously, the purpose of adopting this design is to: ensure that the dishwasher can clean the food residues filtered out by the filtering mechanism 1 while executing the cleaning tableware program, avoid the problem that the working time of the dishwasher is prolonged and the cleaning efficiency of the dishwasher is reduced when the cleaning tableware program ends and the filtering mechanism 1 is cleaned again, improve the intelligent level of the dishwasher, avoid the defect that the user's use experience is poor caused by the artificial periodical cleaning of the filtering mechanism 1, reduce the cost of artificial maintenance of the cleaning mechanism, and further avoid the situation that the filtering efficiency is reduced due to the artificial forgetting of the periodical cleaning of the filtering mechanism 1.

[0058] Preferably, the rotation axis of the sprayer 4 is arranged in different axes with the rotation axis of the cleaning mechanism 2, so that the positions of the sprayer 4 and the cleaning mechanism 2 in the dishwasher can be more flexibly configured to adapt to tableware of different sizes and shapes and cleaning requirements.

[0059] Preferably, the driving shaft 32 of the driving mechanism 3 is arranged in different axes with at least one rotation axis of the sprayer 4 and the cleaning mechanism 2, especially when the sprayer 4 or the cleaning mechanism 2 is maintained and overhauled, the staff can more easily realize the disassembly or installation of the sprayer 4 or the cleaning mechanism 2, which helps to reduce the maintenance cost and shorten the downtime of the dishwasher caused by maintenance.

[0060] More importantly, the driving shaft 32 of the driving mechanism 3 is arranged coaxially with at least one rotating shaft of the sprayer 4 and the cleaning mechanism 2, which helps to reduce resonance phenomenon generated by the sprayer 4 and the cleaning mechanism 2 during operation, reduce vibration generated by the dishwasher during operation, and improve user experience.

[0061] Preferably, the projection of the center of the sprayer 4 is located substantially at the center of the bottom of the inner container, which ensures that the water flow is uniformly sprayed from the center to the periphery, covering the entire space of the inner container and reducing the cleaning dead angle.

[0062] The projection of the center of the driving mechanism 3 and the projection of the center of the filtering mechanism 1 are both arranged away from the center of the bottom of the inner container, which can optimize the space layout inside the dishwasher, help to reduce the interference between various components in the dishwasher, improve the compactness and rationality of the overall structure inside the dishwasher, further avoid friction between various components during operation, reduce the risk of wear and damage of various components, and prolong the service life of the dishwasher.

[0063] Preferably, the cleaning mechanism 2 is sleeved on the outer periphery of the filtering mechanism 1, and is driven by the driving mechanism 3 to rotate relative to the filtering mechanism 1, while the filtering mechanism 1 is cleaned when the cleaning mechanism 2 rotates.

[0064] Further, the cleaning mechanism 2 includes an annular upper support 20, an annular lower support 21, and a cleaning member 22 connected between the upper support 20 and the lower support 21, and the inner side of the cleaning member 22 is at least partially in contact with the outer surface of the filtering mechanism 1 for cleaning the filtering mechanism 1.

It can be understood that the number of cleaning members 22 is at least two, and the two cleaning members 22 are arranged symmetrically relative to the central axis of the upper support 20 or the lower support 21. The upper support 20, the lower support 21 and the two cleaning members 22 form a sleeve-like structure.

[0066] Preferably, the upper support 20, the lower support 21 and the cleaning member 22 are of an integral structure, and preferably, the upper support 20, the lower support 21 and the cleaning member 22 are welded.

[0067] Preferably, in order to improve the cleaning effect of the cleaning mechanism 2, the cleaning member 22 is provided with a plurality of cleaning members, which are distributed at intervals in the circumferential direction of the cleaning mechanism 2.

[0068] Preferably, the multiple cleaning components 22 are evenly spaced in the circumferential direction, ensuring that the cleaning components 22 can fully cover the filter screen 11 on the filter mechanism 1 during rotation, thereby improving the filtration effect of the filter mechanism 1. Furthermore, the evenly spaced distribution of the multiple cleaning components 22 ensures that the force borne by each cleaning component 22 during cleaning is relatively balanced, guaranteeing that the filter screen 11 is subjected to the same force by the cleaning components 22, effectively preventing local wear and damage to the filter screen 11. In addition, the evenly spaced arrangement of multiple cleaning components 22 is more aesthetically pleasing, making the cleaning mechanism 2 look neater.

[0069] Specifically, the filtration mechanism 1 includes a filter and a filter screen 11 installed on the periphery of the filter. The filter has an approximately barrel-shaped structure with an open top and a detachable grid structure. The grid structure filters out larger-sized residues and some larger impurities.

When the cleaning mechanism 2 abuts against the flange on the peripheral wall of the filter, the limiting seat is installed at the lower end of the filter, and the cleaning mechanism 2 is assembled onto the filter. By setting the flange and the limiting seat, the range of motion of the cleaning mechanism 2 in the axial direction of the filter can be limited. Under the drive of the drive mechanism 3, the cleaning mechanism 2 achieves relative rotation with the filter, thereby cleaning the tiny impurities attached to the filter screen 11.

[0071] The filter mechanism 1 also includes a handle, which is integrated with the grid structure at the top of the filter, making it convenient for users to disassemble the grid structure and remove washing impurities from inside the filter.

[0075] A through hole is provided at the bottom of the water tank through which the drive shaft 32 passes, and a sealing ring is provided between the drive shaft 32 and the through hole.

[0076] Preferably, the first external gear ring 23 and the lower bracket 21 are an integral structure.

[0077] Preferably, the drive mechanism 3 includes a second transmission member 34 mounted on the drive shaft 32, and the second transmission member 34 is disposed above the first transmission member 33.

[0078] The second transmission component 34 is connected to the water inlet connector 42 of the dishwasher sprayer 4. The water inlet connector 42 forms the rotating shaft of the sprayer 4 and is installed on the outer periphery of the sprayer bracket.

[0079] The drive motor 31 drives the drive shaft 32 and the second transmission component 34 to rotate together, providing power to drive the sprayer 4 to rotate;
