A drainage control mechanism and washing machine

Abstract

The invention relates to a drainage control mechanism and a washing machine. The drainage control mechanism includes: a valve plug capable of blocking the drain outlet, and a piston rod for driving the movement of the valve plug. , one end of the valve plug holder is fixedly connected with the valve plug, and the other end is movably connected with the piston rod. In the present invention, when the end of the valve plug is not parallel to the bottom of the inner bucket, the movable connection between the piston rod and the valve plug holder can adjust the angle so that the end of the valve plug fits the bottom of the inner bucket to ensure that the valve plug and the drain port There is no gap between them, and the seal is reliable.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a drainage control mechanism and a washing machine. Background technique [0002] In the existing pulsator type washing machine, there is a permeable hole in the inner barrel, and the inner and outer barrels are connected. The water that participates in washing is only the part in the inner tub, which leads to greater waste of water resources. In addition, too much water between the inner and outer tubs will also reduce the concentration of detergent / washing powder in the washing liquid. At the same time, due to the frequent flow of water in and out between the inner barrel and the outer barrel, after continuous use, the area between the side walls of the inner barrel and the outer barrel has also become a space for dirt. The cellulose of clothes, the organic matter of the human body and the dust and bacteria brought in by the clothes are very likely to stay between the side wall...

Problems solved by technology

But long-term operation, because the sealing structure is worn for a long time, it is easy to cause wear and leakage. If the water quality is poor and the sand content is high, the service life will be greatly shortened, and it will not be able to perform its due function.

It is also not suitable for use in the state of large washing capacity, and the reliability is poor

[0004] In the existing research, there is also a washing machine without water between the inner tub and the outer tub during washing. The upper part of the inner tub is provided with a plurality of water throwing holes near the edge, and the bottom of the inner tub is provided with at least one inner tub drain outlet. The drainage control mechanism for blocking the drainage hole, the drainage control mechanism at least includes a retractable valve plug, the valve plug moves upward to close the drainage hole, and the valve plug moves downward to open the drainage hole, but this drainage control mechanism for controlling the drainage of the inner barrel is different Due to the drainage control mechanism that controls the drainage of the outer tub, the inner tub is stationary during washing and rotates during dehydration. The eccentricity of the clothes placed in the inner tub may cause the inner tub to tilt, resulting in gaps in the fit between the valve plug and the inner tub, resulting in blockage weep hole failure
