DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 The utility model provides a technical solution for a filtering device of a washing machine 20.

[0027] A water washing machine filtering device, comprising:

[0028] A filter box 1 is provided in the filter box 1, a filter chamber 2 is provided in the filter chamber 2, a filter plate 3 is fixed in the filter chamber 2, a plurality of filter holes are provided on the filter plate 3, a liquid inlet hole 4 and a liquid outlet hole 5 are provided on the side wall of the filter chamber 2, the liquid inlet hole 4 and the liquid outlet hole 5 are respectively arranged on both sides of the filter plate 3, a sewage hole 21 is provided at the bottom of the filter chamber 2, a sewage pipe 6 is connected to the sewage hole 21, and a sewage valve 7 is installed on the sewage pipe 6;

[0029] A liquid inlet pump 8, which is connected between the washing machine 20 and the liquid inlet hole 4 through a pipeline;

[0030] A liquid outlet pump 9, which is connected between the washing machine 20 and the liquid outlet hole 5 through a pipeline;

[0031] The liquid spraying device comprises a liquid spraying pipe 10 and a liquid spraying pump 11. The liquid spraying pipe 10 is installed in the filter cavity 2. A plurality of nozzles 12 are installed on the liquid spraying pipe 10. One end of the liquid spraying pipe 10 extending out of the filter cavity 2 is connected to the liquid outlet of the liquid spraying pump 11. The nozzle 12 faces the filter plate 3. The liquid inlet of the liquid spraying pump 11 is connected to a water source.

[0032] When the filter plate 3 in the filter box 1 needs to be cleaned, the liquid inlet pump 8 stops working and stops pumping water into the washing machine 20. At this time, the liquid spray pump 11 pumps water into the liquid spray pipe 10, and then the water is sprayed out from the nozzle 12. The sprayed water will rinse the filter plate 3 and rinse off the dirt on the filter plate 3. At this time, the sewage valve 7 is opened, and the washed sewage and dirt flow out from the sewage hole 21 and the sewage pipe 6. After the flushing is completed, the sewage valve 7 and the liquid spray pump 11 are closed, and the liquid inlet pump 8 continues to work. The liquid inlet pump 8 pumps the water in the washing machine 20 into the filter cavity 2, and the liquid outlet pump 9 pumps the water filtered by the filter plate 3 back into the washing machine 20.

[0033] In order to better clean the filter plate 3, a liquid spray outlet pipe 13 is fixed to the liquid outlet of the liquid spray pump 11, and the liquid spray pipe 10 is rotatably connected to the side wall of the filter box 1, and one end of the liquid spray pipe 10 extending out of the filter box 1 is rotatably connected to the liquid spray outlet pipe 13. Since the liquid spray pipe 10 is rotatably connected to the filter box 1, during the process of cleaning the filter plate 3, the nozzle 12 can be driven to rotate by rotating the liquid spray pipe 10, so that the nozzle 12 can spray a wider range and achieve a better cleaning effect.

[0034] The following is a driving method of the liquid spray pipe 10. The end of the liquid spray pipe 10 extending out of the filter box 1 is fixed with a driven gear 14. A connecting bracket 15 is fixed on the outer wall of the filter box 1. A driving motor 16 is fixed on the connecting bracket 15. A driving gear 17 is fixed on the rotating shaft of the driving motor 16. The driving gear 17 is meshed with the driven gear 14. The driving motor 16 drives the driving gear 17 to rotate, and the driving gear 17 drives the driven gear 14 to rotate, thereby driving the liquid spray pipe 10 to rotate.

[0035] A liquid inlet valve 18 is installed on the pipeline between the liquid inlet pump 8 and the liquid inlet hole 4. When the liquid is normally inlet, the liquid inlet valve 18 is opened, and when the liquid is cleaned, the liquid inlet valve 18 is closed. A liquid outlet valve 19 is installed on the pipeline between the liquid outlet pump 9 and the liquid outlet hole 5. When the liquid is normally inlet, the liquid outlet valve 19 is opened, and when the liquid is cleaned, the liquid outlet valve 19 is closed. A liquid spraying valve 22 is installed on the liquid spraying outlet pipe 13. When liquid spraying is required, the liquid spraying valve 22 is opened, and when liquid spraying is not required, the liquid spraying valve 22 is closed.

[0036] There are two liquid spraying devices, and the two liquid spraying devices spray the filter plate 3 from both sides of the filter plate 3 to clean it more thoroughly.

[0037] The following is a rotational connection method between the spray pipe and the spray outlet pipe. A rotating convex ring 23 is fixed to the inner wall of the spray outlet pipe outlet, and a rotating annular groove 24 is provided on the outer wall of the spray pipe. The rotating convex ring 23 is installed in the rotating annular groove 24, and the rotating convex ring 23 can be rotatably connected relative to the rotating annular groove 24.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
