Drain valve assembly and washing machine

Abstract

The invention belongs to the technical field of washing machines, and discloses a drain valve assembly and a washing machine, the drain valve assembly comprises a valve plug and a driving part driving the valve plug to move, the driving part comprises a centrifugal sliding block and a reversing transmission mechanism, and the reversing transmission mechanism is connected with the centrifugal sliding block and the valve plug; the centrifugal sliding block slides under the action of centrifugal force and drives the valve plug to move through the reversing transmission mechanism. The sliding direction of the centrifugal sliding block is different from the moving direction of the valve plug. According to the drainage valve assembly, the reversing transmission mechanism is arranged, so that the centrifugal sliding block and the valve plug can move in different directions, when the drainage valve assembly is applied to the washing machine to achieve centrifugal drainage, the installation position of the drainage valve assembly is more flexible, meanwhile, the installation space can be saved, and expansion of an inner barrel of the washing machine is facilitated.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a drain valve assembly and a washing machine. Background technique [0002] Most of the existing washing machines include an outer tub and an inner tub disposed inside the outer tub, and a plurality of dewatering holes are arranged on the tub wall of the inner tub, so that the inner tub and the outer tub communicate with each other. When the washing machine is working, the outer bucket holds washing water, and the inner bucket holds the laundry to be washed. The washing water can exist between the inner and outer buckets, but this part of the washing water will not be used, resulting in a waste of washing water. Moreover, as the working time of the washing machine increases, the dirt and lint in the washing water will remain in the space between the inner tub and the outer tub, which is difficult to clean, resulting in bacteria and odors caused by perennial u...

Problems solved by technology

[0004] However, in the above scheme, the valve plug slides along the radial direction of the inner barrel to open / block the drainage hole, and the sealing effect is not ideal due to the influence of water pressure

At the same time, limited by the rotational speed of the pulsator washing machine, the centrifugal force provided by the centrifugal block is limited, and the drain sealing device may not be able to open the drain hole

Adding a drainage sealing device under the inner barrel occupies the space at the bottom of the inner barrel, which is not conducive to the expansion of the inner barrel

And if the installation position of the drainage sealing device in the above-mentioned scheme is changed, since the valve plug and the centrifugal block slide radially along the inner barrel synchronously, it can only be arranged on the barrel wall of the inner barrel, that is, a drain hole is opened on the barrel wall. Because the drainage hole is set at the bottom of the barrel, the drainage efficiency will be reduced
