Drainage device and washing machine

Abstract

The invention belongs to the technical field of washing machines and particularly relates to a drainage device and a washing machine. The drainage device comprises a shell with a filter cavity, the filtering device is arranged in the filtering cavity, the shell is providedwith a water inlet ,a circulating water outlet and a water outlet which can be communicated with the filter cavity, the circulating water outlet is connected with a circulating pump, the circulating pump and the circulating water outlet are arranged at one end part of the shell, the filtering device enables a first waterway and a second waterway to be formed in the filtering cavity, the first waterway filters purified water and outputs the water through the circulating water outlet, and the second waterway drains water and discharges filtered materials intercepted by the first waterway at the same time. The drainage device is simple in structure and good in scrap removing effect, automatic cleaning can be achieved, the trouble of manual disassembling and cleaning is avoided, the structural space of the washing machine does not need to be increased, and a larger installation space is not needed.

Description

Technical field [0001] The invention belongs to the technical field of washing machines, and specifically relates to a drainage device and a washing machine. Background technique [0002] While the washing ratio of the existing drum washing machine is increased, the rate of wear on the clothes also gradually increases, resulting in an increase in lint in the washing water during washing, which tends to remain on the clothes and cannot be washed. Not only is it troublesome to washing clothes, but it is also easy to breed bacteria and pollute clothes. A drain pump filter is installed in the drum washing machine to filter large debris such as coins, but it cannot filter the thread debris in the water. [0003] The existing pulsator washing machine has generally adopted a manually detachable lint filter to clean the lint during the washing process. However, after each washing or after a period of time, it needs to be manually disassembled for scouring and washing to remove thread scr...

AI Technical Summary

Problems solved by technology

This solution has a better effect of removing lint, but the cost is high, the washing machine occupies an increased area, the structure is complicated, and the operation of adding flocculants and coagulants is difficult

[0006] Therefore, the existing washing machine generally installs a coarse filter device at the water inlet of the washing machine or at the bottom of the washing machine to filter and retain larger particles suspended in the incoming water or washing and rinsing water such as lint, but there is no circulation filtering function and no self-cleaning Function, limited water purification effect, poor user experience

Or the structural setting is too complicated, the cost is high, and it is difficult to promote in the market
