Water-saving washing machine drainage device and washing machine

Abstract

The invention discloses a water-saving washing machine drainage device. The water-saving washing machine drainage device comprises an outer drum, an inner drum located in the outer drum, a drainage hole and a drainage sealing device; the drainage hole is formed in the bottom of the inner drum and communicated with an inner cavity of the inner drum and an inner cavity of the outer drum; the drainage sealing device is arranged between the drainage hole and the bottom of the outer drum; the drainage sealing device comprises a drainage driving device and a corrugated pipe; the drainage driving device drives the corrugated pipe to stretch out or draw back to seal and close or open the drainage hole. The water-saving washing machine drainage device achieves the function of achieving no water between the outer drum and the inner drum by using the drainage driving device to drive the corrugated pipe to stretch out or draw back to seal and close or open the drainage hole, water sources are saved, and meanwhile, dirt storage and accumulation between the outer drum and the inner drum can be avoided. The invention further provides a washing machine with the water-saving washing machine drainage device.

Description

Technical field [0001] The present invention relates to the technical field of washing machines, in particular to a water-saving washing machine drain device, and also to a washing machine having the water-saving washing machine drain device. Background technique [0002] From a national perspective, the current popularity of my country’s washing machine market has exceeded 76%, of which the urban market has exceeded 96%, and the rural market has exceeded 53%. With the country’s policy of promoting home appliances to the countryside and expanding domestic demand, washing machine Companies have set their sights on rural markets with greater consumption potential. In this huge market, companies are paying more and more attention to the improvement of washing machine performance to meet the needs of users.

Problems solved by technology

[0003] However, in the existing pulsator washing machine, the part of water filled between the inner cylinder and the side wall of the outer cylinder does not participate in washing, and the water that really participates in washing is only The part in the inner cylinder, which causes a large waste of water resources, and too much water between the inner and outer cylinders will also reduce the concentration of detergent or washing powder in the washing liquid, resulting in waste; and the area between the inner cylinder and the outer cylinder It has also become a space for dirt and dirt, such as scale in tap water, free matter in washing powder, cellulose in clothes, organic matter in the human body, and dust and bacteria brought in by clothes are very easy to stay on the side walls of the inner cylinder and the outer cylinder between
