Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, and more specifically to a filter screen component of a washing machine. Background Art

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. The filter of the washing machine is one of the key accessories. The filter is needed to filter the water when water is entering, and the filter is needed to filter the hair produced by the friction between clothes when washing. Due to the different water quality in different regions of my country, there will be some tiny sand and other granular substances in daily water use. Therefore, a water inlet filter is needed to filter the water to prevent the granular substances from dirtying the clothes, which will also damage the washing machine and shorten its service life. At the same time, it plays a role in protecting the washing machine. Water must be filtered before it can be used. When setting a filter at the water inlet, the filter is installed together with the automatic water inlet device, and its outer side is tied together with the water inlet of the washing machine by steel wire. After the filter has been used for a long time, a series of particulate impurities will accumulate on the filter, resulting in poor filtering effect and inconvenience in disassembly. At the same time, long-term water flow impact will cause certain damage to the filter, reducing the service life of the filter. Utility Model Content

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The filter assembly of a washing machine involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0017] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0018] Embodiment 1

[0019] Reference Figure 1-5 , a filter assembly for a washing machine, firstly, a speed reduction fan 13 is installed at the bottom of a connecting shaft 12, then the connecting shaft 12 is installed on the outside of a connecting column 9, and then the filter ball 10 is installed on both sides of the connecting shaft 12 outside the connecting column 9, and then the connecting column 9 is installed inside a guide tube 7, and then the metal filter 11 is installed at the bottom of the guide tube 7, and then the card plate 8 is installed on the top of the guide tube 7, and then the guide tube 7 is installed inside a connecting filter tube 4, and then the sealing plate 6 is installed on the top of a rotating ring 5, and then the rotating ring 5 is installed on the top of the connecting filter tube 4, and then the No. 2 sealing ring 14 is installed on the inner side of the bottom of the connecting filter tube 4, and then a rotating groove 3 is opened on the inner side of the bottom of an automatic water inlet device 1, and then the No. 1 sealing ring 2 is installed on the inner side of the bottom of the automatic water inlet device 1, and then the connecting filter tube 4 is screwed into the bottom of the automatic water inlet device 1, and finally the No. 2 sealing ring 14 is installed on the inner side of the bottom of the connecting filter tube 4, and the sealing assembly 15 is screwed into the bottom of the connecting filter tube 4 to fix it.

[0020] The working principle of the utility model is as follows: the staff connects the water inlet pipe to one end of the automatic water inlet device 1, and then connects one end of the sealing assembly 15 to the water inlet of the washing machine, and then after the whole is installed, the rotating ring 5 and the rotating groove 3 rotate together, and then the sealing plate 6 on the top of the rotating ring 5 is tightly clamped with the No. 1 sealing ring 2 inside the automatic water inlet device 1, and the connection between the sealing assembly 15 and the connecting filter tube 4 is also the same, thereby increasing the connection sealing between the automatic water inlet device 1, the connecting filter tube 4, and the sealing assembly 15; at the same time, water flows into the automatic water inlet device 1 and rushes to the outside of the connecting column 9 On the filter ball 10, at this time, the filter ball 10 performs initial adsorption filtration on the water flow that impacts its outer side and slows down the speed of the water flow. The slowed water flow impacts the speed reduction fan 13 along the guide tube 7, so that the inclined fan blades on the outer side of the speed reduction fan 13 drive the speed reduction fan 13 to start rotating. The rotating speed reduction fan 13 splashes the water flow around the inner side of the metal filter mesh 11, so that the water flow first impacts the inner wall of the metal filter mesh 11, and then flows to the bottom along its inner wall for filtration, thereby preventing the water flow from directly impacting the filter mesh at the bottom of the metal filter mesh 11, thereby damaging the filter mesh, and increasing the service life of the metal filter mesh 11 and its filter mesh.

[0021] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
