The existing water purifier structure includes a housing and a filter element located in the housing, and there is a certain gap between the filter core and the housing. This gap is a water inlet channel, and the housing is provided with a purified water outlet, tap water Inlet and tap water outlet, during the purification process of the water purifier, various impurities and harmful substances in the tap water will gradually absorb and accumulate on the outer surface of the filter element. Therefore, when the water purifier is used for a long time, the purification effect of the filter element will be greatly improved. weakened, the filter element needs to be replaced

Embodiment Construction
[0024] Referring to the accompanying drawings, the specific implementation method of the present invention is that a high-speed fluid space 2 is set between the shell 1 and the inner filter core 4 of the water purifier, so that the flow direction of tap water in this high-speed fluid space 2 is tangent to the outer surface of the inner filter core 4 , the water flow velocity in this high-speed fluid space 2 is more than 5 times of the water flow velocity in the water inlet, and the high-speed fluid space 2 is divided into front and rear through, reciprocating and tortuous high-speed flow channels by setting a partition plate 23, so as to improve the flow rate in the high-speed fluid space. Water flow velocity; at the same time, between the high-speed fluid space 2 and the inner filter element 4, a layer of 2.5 micron pore size particle impurity barrier layer 3 is set between the high-speed fluid space 2 and the inner filter element 4 on the outer surface of the inner filter elem...

The invention discloses a self-cleaning method of a water purifier. According to the method, a high speed fluid space is arranged between a shell and an inner filter element of the water purifier, the flow direction of tap water in the high speed fluid space is tangential to the outer surface of the inner filter element, a water inlet and a water outlet are formed in the high speed fluid space, when the purifier is in use, the water inlet and the water outlet in the high speed fluid space are opened at the same time, at the moment, the tap water flows by the high speed fluid space along the tangential direction to scour filtering residues on the outer surface of the inner filter element via high speed water flow to achieve self cleaning, water containing the filtering residues flows out from the water outlet is used as non-drinking washing water, and thus the self-cleaning of the water purifier is achieved when domestic washing water is obtained. According to the self-cleaning method disclosed by the invention, not only can the quality of purified water be improved, and particularly the service life of the filter element can be prolonged.
Description
technical field [0001] The invention relates to the technical field of water purification, in particular to a self-cleaning method for a water purifier. Background technique [0002] In recent years, with the intensification of environmental pollution, people's requirements for drinking water have become increasingly strict, and water purifiers have gradually entered thousands of households and become a necessity of life. The existing water purifier structure includes a housing and a filter element located in the housing, and there is a certain gap between the filter core and the housing. This gap is a water inlet channel, and the housing is provided with a purified water outlet, tap water Inlet and tap water outlet, during the purification process of the water purifier, various impurities and harmful substances in the tap water will gradually absorb and accumulate on the outer surface of the filter element. Therefore, when the water purifier is used for a long time, the pur...
