Washing machine filtering assembly and washing machine

Abstract

The invention provides a washing machine filtering assembly and a washing machine; the filtering assembly comprises a preposition filter and a filtering membrane assembly; a water distributing gas distribution member is arranged in a fluid path between the preposition filter and the filtering membrane assembly, so the fluid from a water outlet of the preposition filter is split by the water distributing gas distribution member and then enters the filtering membrane assembly. The filtering assembly is well applied to the washing machine having a circulating water filtration system so as to filter washing water and / or rinsing water; furthermore, the filtering assembly is applied to the washing machine so as to solve thread chips blocking problems, and can be conveniently cleaned online, thus prolonging the life of the filtering assembly of the washing machine, and ensuring the filtering assembly to have a high filtering flux.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a filter assembly suitable for washing machines and a washing machine with a circulating water filtering system. 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 each rinse needs to consume a large amount of clean water. Generally speaking, the water consumption of the entire working process of the existing pulsator washing machine can reach 20-30 liters per kilogram of clothing, while the water consumption of the entire working process of the existing drum washing machine can also reach 12 liters of water per kilogram of clothing. That is to say, when the existing conventional washing machine (no matter the pulsator type washing machine or the drum type washing machine, and no matter whether it is a semi-automatic washing machine or ...

AI Technical Summary

Problems solved by technology

However, because the rinsing water has many impurities and the water quality is unstable, the solution 1 cannot really solve the water quality problem of the rinsing water

Moreover, this solution usually requires manual cleaning of the water storage tank and filter screen, which is inconvenient for maintenance

[0009] Option 2 uses a reverse osmosis filter to purify laundry wastewater, which not only requires the use of a high-pressure pump, but also has a slow purification rate, and the water output is difficult to meet the normal use requirements of the washing machine

In addition, this solution requires regular replacement of the reverse osmosis filter, which is costly

[0010] Option 3 uses large-scale water treatment devices and auxiliary equipment such as ozone generators to purify laundry wastewater. These auxiliary equipment are not only expensive in themselves, occupy a large space, but also require many supporting devices and related cleaning devices, further greatly increasing equipment costs and maintenance. cost, totally unsuitable for ordinary household use

[0011] It can be seen that in the washing machine itself with a circulating water filtration system, such as the washing machine according to the aforementioned schemes 1 and 2, the filter screen and the reverse osmosis filter used in it are common in the field of water treatment technology, and when assembled on the washing machine, they are not Does not consider the structure and pipeline setting characteristics of the washing machine itself

Moreover, the filter assembly in the existing washing machine will be polluted when filtering, causing the filtration flux to gradually decrease with the running time, because the existing filter assembly used in the washing machine cannot be cleaned without disassembly, resulting in its It is troublesome to clean or needs to be replaced more frequently, and the service life is short
