Drum type washing machine with retractable drum and drum retracting method

Abstract

The invention provides a drum type washing machine with a retractable drum and a drum retracting method. The washing machine comprises an outer drum assembly including a first outer drum and a second outer drum which is sleeved with the first outer drum and capable of retracting. The washing machine further comprises a door body and an inner drum assembly. The door body is arranged at the front end of the second outer drum. The inner drum assembly is provided with a first inner drum and a second inner drum which is sleeved with the first inner drum and capable of retracting. A structure ensuring synchronous retraction is arranged between the second outer drum and the second inner drum. By arranging the retractable second outer drum and the second inner drum, the volume of the inner drum of the washing machine is adjusted. By arranging the door body at the front end of the second outer drum, clothes are conveniently placed and the door body and the second outer drum can be conveniently sealed. In addition, operation is not required to be performed on the second outer drum and the second inner drum respectively due to the structure for synchronous retraction between the second outer drum and the second inner drum. Therefore, operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a drum washing machine with a retractable cylinder and a method for expanding and contracting the cylinder of the washing machine. Background technique [0002] With the development of science and technology and the improvement of people's living standards, users' requirements for washing machines are also constantly increasing, such as increasing the washing capacity while maintaining the same performance indicators. However, simply increasing the washing capacity of the washing machine means increasing the volumes of the inner and outer tubs and casings of the washing machine. Generally speaking, the larger the washing capacity of the washing machine, the larger its volume and the larger the space occupied by the user. [0003] The retractable washing machines in the prior art are all for the purpose of portability. They are based on the concept of lightne...
