TECHNICAL FIELD The present application relates to the technical field of washing equipment, for example, to a drum-type washing machine.

As the most widely used household appliance in daily life, washing machines have helped people with their laundry problems and brought great convenience to people. However, washing machines also have certain drawbacks, such as taking a long time and consuming a large amount of water.As society develops, water resources become more and more important as an important natural resource, and people's People are also becoming more conscious of saving water. It is especially important to realize the water-saving function of washing machines.

In order to solve the water saving problem of washing machines, for example, the Chinese patent application with the application number CN201410215346.3 and the name of drum type washing machine includes a housing, and an inner tank and an outer tank are provided in the housing, A door seal is provided between the outer tank and the housing, the inner tank is in contact with the driving device, the inner tank is a non-porous inner tank, and the inner tank has a small diameter tank bottom; It is a tapered tank with a large diameter tank opening, and the opening of the inner tank is tapered inward to form an arc shape.
