Washing machine and control method for sterilizing filter components of washing machine

Abstract

The invention provides a washing machine and a control method for disinfection of a filter component of the washing machine. The washing machine comprises a circulating water filter system which comprises the filter component, an air flow supply device, and an ozone supply device. The filter component is configured to filter water discharged from a washing drum of the washing machine so that the water can be circulated and sent back to the washing drum for reuse. The air flow supply device is configured to supply air flow to the filter component for air washing of the filter component. The ozone supply device is configured to provide ozone-containing gas, and the ozone-containing gas is carried into the filter component by the air flow to disinfect the filter component. When the air washing of the filter component is performed, the ozone-containing gas is carried into the filter component by the air flow to disinfect the filter component, so that bacterium breeding in the filter component is reduced, the peculiar smell of produced water of the filter component is greatly reduced and users can enjoy better user experience.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine with a circulating water filtering system and a control method for sterilizing 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 w...

AI Technical Summary

Problems solved by technology

However, with the increase in washing times of the washing machine, separated substances and some other impurities will gradually accumulate on the surface of the filter membrane, causing blockage and pollution of the filter membrane, which will greatly affect the filtering effect

In addition, because the filter membrane of the filter module can retain bacteria, the bacteria multiply and decompose on the surface of the filter membrane, causing the water produced by the filter module to have a peculiar smell when it is filtered again, which affects the user's laundry.

Moreover, some bacteria in the filter membrane will also enter the washing tub together with the produced water, causing pollution to other clothes and affecting the health of users

Although emptying the water in the filter membrane can reduce the generation of odor, the bactericidal effect of this method is not obvious, and the produced water will still have odor during the next filtration
