Washing machine without water between barrels and control method

Abstract

The invention relates to a washing machine without water between barrels and a control method. The washing machine comprises an outer barrel, an inner barrel, an air chamber and a pressure sensor, wherein the pressure sensor is connected with the air chamber. A plurality of water throwing holes are formed in the upper portion of the inner barrel and close to the edge of the inner barrel, at least one inner barrel drain port is formed in the bottom of the inner barrel, telescopic drain valves capable of plugging the inner barrel drain ports are arranged at the bottom of the outer barrel, an outer barrel drain port is formed in the bottom of the outer barrel and provided with a washing machine drain pipeline, and the air chamber communicated with the inner barrel is arranged on the outer barrel and provided with an air chamber drain port capable of draining water in the air chamber. The washing machine thoroughly drains the water without residual water and is high in drain speed, accurate in water level detection and simple in structure, stay of water flow between the inner barrel and the outer barrel is avoided, dirt is prevented from staining the inner wall of the outer barrel, the residual water in the air chamber is avoided, errors caused by reuse of water level detection are avoided, the residual water is prevented from breeding bacteria in the air chamber, the outer barrel is communicated with the inner barrel through the telescopic drain valves, and line chip blockage is avoided.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a waterless washing machine between tubs and a control method. 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 th...

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
