During the twisting process of the flexible drum 13, the clothes and the clothes, and the clothes and the inner wall of the flexible drum 13 can be fully rubbed and extruded mutually, so that the rubbing type washing process can be better simulated. In the washing process, the flexible cylinder 13 can be driven to rotate forward and rotate to the end, and then rotate backward and rotate to the end, namely the forward rotation and the backward rotation of the flexible cylinder are alternately carried out until the whole rubbing type washing process is completed.
