Non-return device of clothes treatment equipment and clothes treatment equipment

Abstract

The invention discloses a non-return device of clothes treatment equipment and the clothes treatment equipment, and belongs to the technical field of household appliances. The non-return device comprises a main channel for fluid to flow, a non-return piece and a bypass channel; the non-return piece is arranged in the main channel and has an opening state allowing downstream fluid in the main channel to pass through and a closing state preventing countercurrent fluid in the main channel from passing through; and the bypass channel is communicated with the main channel and is used for dredging countercurrent fluid in the main channel when the non-return piece is in the closed state. After the countercurrent fluid enters the main channel, the non-return piece is in the closed state to prevent the countercurrent fluid from passing through the non-return piece, and part of the countercurrent fluid blocked by the non-return piece is guided outwards from the bypass channel, so that the burden of the non-return piece is relieved, and the risk that the non-return piece is permeated by the countercurrent fluid and even fails is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of household appliances, in particular to a non-return device for clothes treatment equipment and the clothes treatment equipment. 【Background technique】 [0002] A known laundry processing device (such as a drum washing machine, an integrated washing and drying machine, etc.) has a water tub and a washing tub, the washing tub is rotatably arranged in the water tub, and during the washing process, the clothes are washed in the washing tub The rotation of the bucket drives the tumbling, and the joint action of washing water and detergent achieves the washing effect of clothes. [0003] The above-mentioned clothes processing equipment is usually equipped with a drying device, a nursing device, etc., and these devices send hot air, nursing media and other fluids into the bucket through the fluid channel, and perform drying, deodorizing, antibacterial, wrinkle-removing and other functions on the clothes.

AI Technical Summary

Problems solved by technology

During the washing process, a large amount of foam is generated in the bucket and the washing tub. With the operation of the washing tub, fluids such as foam and washing water will be squeezed out and flow in the reverse direction (opposite to the fluid flow direction in the original fluid channel) into the above-mentioned In the fluid channel, there are problems such as foam overflow and electronic devices being damp. The commonly used non-return means in the prior art is to add a non-return structure (such as a check valve, a non-return sheet, etc.) in the fluid channel to block the reverse flow of fluid (such as the above foam, washing water), however, when the counterflow flow is large and lasts for a long time, a large amount of counterflow fluid will accumulate in front of the non-return structure, which will easily lead to leakage or even failure of the non-return structure
