Description

Technical Field

[0001] The utility model belongs to the technical field of washing machines, and particularly relates to a sewage filter device for washing machines. Background Art

[0002] The wastewater generated by the washing machine during operation needs to be filtered through a filtering device to avoid direct discharge of sewage, which may cause the drainage pipe to be blocked by objects in the sewage, or make some objects in the sewage unable to be easily retrieved. The existing sewage filter device for washing machines can meet the basic needs of sewage filtering and can make it convenient for users to disassemble the filter structure for cleaning. However, the sewage filter structure used often cannot automatically clear the filter structure during operation, so it is easy to cause a large number of filter holes in the filter structure to be blocked in a short time, so that users need to disassemble and clean the filter structure every short time, which will bring great inconvenience to people's use.

[0026] like Figure 1 , 2As shown in Figures 3, 4, 5, 6 and 7, a sewage filter device for a washing machine comprises a sewage treatment cylinder 102 which is detachably arranged at the lower end of the interior of a washing machine housing 101 and has an opening at the front end, a filter cylinder 103 with an opening at the front end is arranged on the rear side wall of the sewage treatment cylinder 102, a U-shaped fixing frame 104 which is located at the rear side of the filter cylinder 103 is arranged at the rear side end of the washing machine housing 101, a driving motor 105 whose output shaft extends to the front side of the fixing frame 104 is arranged at the front side end of the fixing frame 104, a plug-in cylinder 106 is arranged on the output shaft of the driving motor 105, a connecting shaft 107 is penetrated and rotatably arranged at the rear side end of the filter cylinder 103, a U-shaped cleaning brush 108 is arranged at the front side end of the connecting shaft 107, and a plug-in cylinder 106 is arranged at the rear side end of the connecting shaft 107 A matching plug-in rod 109 is provided, a water inlet conduit 110 extending to the inside of the filter cartridge 103 is penetrated through the top of the sewage treatment cartridge 102, and a water outlet conduit 111 is provided at the bottom of the sewage treatment cartridge 102. A drain hose 113 is provided inside the washing machine housing 101, one end of which is connected to the cleaning chamber 112 and the other end is clamped and fixed to the water inlet conduit 110. A water outlet hose 114 is penetrated through the side wall of the washing machine housing 101, one end of which is connected to the sewer pipe and the other end is plugged and fixed to the water outlet conduit. A first cover plate 115 is also screwed on the bottom of the front end of the washing machine, a second cover plate 116 is also screwed on the front side end of the sewage treatment cartridge 102, and a sealing plug 117 matching the front side end of the filter cartridge 103 is also provided on the rear side end of the second cover plate 116.

[0027] like Figure 4 , 5 As shown in Figures 7 and 8, the longitudinal section of the plug rod 109 is a rectangle, and the longitudinal section of the plug hole inside the plug tube 106 is a rectangle.

[0028] like Figure 2 , 3 As shown, a manual valve 201 is also provided on the water outlet conduit 111. Before the water outlet hose 114 is separated from the water outlet conduit 111, the manual valve 201 can be closed to prevent the water outlet hose 114 from being separated from the water outlet conduit 111 and the remaining water in the treatment cylinder body from being randomly spilled.

[0029] like Figure 2 , 3As shown, a fixing slot 202 located below the sewage treatment barrel 102 is also provided on the bottom inner wall of the washing machine housing 101, and a fixing plug plate 203 respectively matched with the fixing slot 202 is provided at the bottom of the sewage treatment barrel 102, and a fixing bolt 204 for screwing and fixing the fixing plug plate 203 is also provided on the fixing slot 202, and a threaded fixing hole matched with the fixing bolt 204 is provided on the fixing plug plate 203.

The sewage generated by the washing machine will enter the filter cartridge 103 through the drain hose 113 and the water inlet pipe 110, and the sewage will pass through the filter holes of the filter cartridge 103 to leave the filter cartridge 103 and enter the gap between the sewage treatment cartridge 102 and the filter cartridge 103, and then leave the sewage treatment cartridge 102 through the outlet pipe 111, and be discharged into the sewer pipe through the outlet hose 114. Dirt and other items in the sewage will be retained in the filter cartridge 103 because they cannot pass through the filter holes of the filter cartridge 103.

[0032] During the sewage filtering process, the driving motor 105 can be started to rotate the plug rod 109, the plug cylinder 106, the connecting shaft 107, and the cleaning brush 108, and the cleaning brush 108 can clean the dirt adhering to the inner wall of the filter cylinder 103, thereby avoiding a large number of filter holes of the filter cylinder 103 from being blocked; after a period of time, when the filter cylinder 103 needs to be cleaned, the manual valve 201 can be closed, and the plug cylinder 106 and the plug rod 109 can be separated, the drain hose 113 and the water inlet conduit 110 can be separated, and the plug rod 109 and the plug cylinder 106 can be separated, and then the sewage treatment cylinder 102 and the filter cylinder 103 can be taken out of the washing machine housing 101, and then the second cover plate 116 can be opened, and then the inside of the filter cylinder 103 and the cleaning brush 108 can be cleaned.

[0033] According to another embodiment of the present invention, Figure 3 , 7 As shown, the cleaning brush 108 is provided with a connecting cylinder 301 that is clamped and fixed with the connecting shaft 107, and the cleaning brush 108 is also provided with a connecting bolt 302 for screwing and fixing the connecting shaft 107, and the connecting shaft 107 is provided with a threaded connection hole that matches the connecting bolt 302. The connecting cylinder 301 can be clamped and fixed with the front side end of the connecting shaft 107, and then the connecting bolt 302 passes through the side wall of the cleaning brush 108 and is screwed and fixed with the threaded connection hole, so that the cleaning brush 108 and the connecting shaft 107 can be flexibly fixed, so that the user can easily replace the worn cleaning brush 108.

[0034] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
