Abstract

The invention provides a washing machine filtering assembly self-cleaning method comprising the following steps: receiving a user operation order used for starting a self-cleaning program; executing the self-cleaning program so as to clean a washing machine filtering assembly, and only receiving the following user operation orders before the self-cleaning program is finished: stopping the washing machine order, pausing the self-cleaning program order, and canceling the self-cleaning program pausing state order; other user operation orders besides the stopping washing machine order, pausing the self-cleaning program order, and canceling the self-cleaning program pausing state order are forbidden to receive or neglected. In a filtering assembly cleaning process of the self-cleaning program, the washing machine cannot receive or neglect other user operation orders besides the stopping washing machine order, pausing the self-cleaning program order, and canceling the self-cleaning program pausing state order, so the washing machine filtering assembly can be thoroughly cleaned, thus prolonging the filtering assembly life, and ensuring the filtering assembly to have a high filtering flux.

Description

technical field

[0001] The invention relates to a washing machine, in particular to a self-cleaning method for a filter assembly of the washing machine. Background technique

[0002] The working process of conventional washing machines usually includes water intake, washing-spin-drying-drainage, multiple rinsing-spin-drying-drainage, etc., wherein washing and each rinse need to consume a large amount of clean water. The water used for washing or rinsing is discharged to the environment outside the washing machine through the drain pipe. The whole washing process consumes a lot of water, which greatly wastes water resources.

[0003] In order to achieve the purpose of saving water, the washing water and / or rinsing water of the washing machine can be filtered by the filter assembly for recycling. However, as the washing times of the washing machine increase, separated substances and some other impurities will gradually accumulate on the surface of the filter membrane, causin...

Embodiment Construction

[0031] figure 1 is a schematic schematic diagram of a washing machine according to an embodiment of the present invention. The washing machine may include a washing tub 12, a drain pump 22, and a filter assembly. The filter assembly includes a pre-filter 24 and an ultrafiltration membrane assembly 26 . The washing tub 12 is generally composed of an outer tub and an inner tub that can rotate in the outer tub. Washing tub 12 top is provided with clear water inlet, and it connects tap water outlet by pipeline 11, when opening valve 13 on the pipeline 11, can enter washing with clear water or rinse with clear water in washing tub 12. The lower part of the washing tub 12 is provided with a drain port, and the drain port communicates with the filter assembly via a drain pump 22 through a pipeline. The water production port of the ultrafiltration membrane module 26 communicates with the washing tub 12 through the water inlet pipeline 14 . When using the clean water washing functi...
