Water level detection structure for buckets waterless washing machine and washing machine

Abstract

The invention relates to a water level detection structure for buckets waterless washing machine and a washing machine. The upper part of an inner barrel is provided with a plurality of water throwing holes near the edge, the bottom of the inner barrel is provided with at least one inner barrel drain outlet, the bottom of an outer barrel is provided with a telescopic drain valve which can block the inner bucket drain outlet, an air chamber is installed on the outer barrel, and a pressure sensor is arranged on the air chamber, which is connected with the inner barrel through a telescopic drain valve, the air chamber is provided with an air chamber drain outlet capable of draining water from the air chamber. The washing machine has the advantages of the complete drainage without any residual and fast drainage rate, water can be avoided to stop between the inner and the outer barrels, and dirt is prevented from being stained on the inner wall of the outer barrel. The water level detection is accurate, the structure is simple, and no residual water remains in the air chamber, which avoid an error when the water level detection is used again, also avoid the residual water to breed bacteria in the air chamber, and the line debris blockage is avoided through the connection between the telescopic drain valve and the inner barrel.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a water level detection structure for an anhydrous washing machine between tubs and the 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 ...

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
