Washer

Abstract

The invention provides a washer. The washer comprises a circulating water filter system. The circulating water filter system is configured that water in a washing cylinder of the washer flows into the circulating water filter system in at least one operating flow of the washer, and then circularly flows back the washing cylinder after the water is filtered in the circulating water filter system; the circulating water filter system comprises at least two filters which are connected serially, and the at least two filters are arranged to be an integrated component. According to the washer provided by the invention, the circulating water filter system is compact in structure and convenient to mount / dismount.

Description

technical field [0001] The invention relates to a washing machine, in particular to 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 (regardless of the pulsator washing machine or the drum washing machine, and no matter whether it is a semi-automatic washing machine or a fully automatic washing machine) is working, it generally discharges ...

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
