Washing machine self-cleaning circulating filtering system and self-cleaning method

Abstract

The invention discloses a washing machine self-cleaning circulating filtering system and a self-cleaning method. The system comprises a water storage tank communicated with a washing machine, a filter module disposed in the water storage tank and processing water and a siphon pipeline communicated with the water storage tank, wherein the internal space of the water storage tank is divided into two cavities; the two cavities are communicated via the filter module; the two cavities are a first cavity to filter drainage water in a washing machine water accommodating barrel, and a second cavity discharging the filtered water to the water accommodating barrel; one end of the siphon pipeline is communicated with the first cavity and the other end lifts, then passes through a washing machine body and then descends; a highest point of the siphon pipeline is higher than a height between a water outlet position of the water storage tank and a circulating water inlet position of the water accommodating barrel; when the filter module is blocked, large absorption force is formed in the siphon pipeline due to the siphon principle, so block can be automatically cleaned and back wash can be formed; after cleaning is finished, the siphon is automatically destroyed and circulating water is continued; and the washing machine self-cleaning circulating filtering system is simply structured, requires low cost, and hand-operated block cleaning work via circulating water program stop can be avoided.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine circulating water system, in particular to a washing machine self-cleaning circulating filter system and a self-cleaning method. Background technique [0002] In order to save water, the existing washing machine has been improved and adopts a circulating water purification method, including: a bucket used to hold washing water; a washing bucket used to hold laundry clothes; a circulating water circuit with a water filter device . The washing water enters the water filter device through the three-way pipe of the drainage pump, and then enters the water tank for washing after being filtered, so as to save water. [0003] There are many ways to filter and treat water in washing machines. The most common one is to use a filter to filter and then spray for washing. After the water is filtered by the filter device, the flocs, etc. are filtered and discharged into the...

AI Technical Summary

Problems solved by technology

However, in the process of filtering washing water or rinsing water, as the washing cycle increases, impurities will gradually accumulate on the filter membrane or even block it, and the filter will lose its filtering function.

[0006] This kind of filter membrane water purification method is classified according to the filtration grade of the filter membrane, so that it can be applied to the purification of tap water in the family to make the effluent water directly drinkable, and it can also be applied to the treatment of industrial water, because the household water purification drinking is for the treatment of tap water , the amount of treated water is small and there are few impurities in tap water. Generally, the filter membrane needs to be cleaned after half a year to one year. The time for cleaning and filtering impurities is relatively fixed, while the amount of industrial water is relatively large. , Generally, chemicals, chlorine, etc. are used to deal with the clogging of organic matter, while acid is needed to deal with the clogging of inorganic matter, which is extremely harmful to the washing machine and laundry, and is not suitable for the field of washing machine
