Background

Generally, a drum of a washing machine, which accommodates laundry, is rotatably disposed within an outer tub, which is used to provide water. The drum is formed with through holes, so that the water inside the outer tub flows into the drum through the through holes, and the washed matter moves with the rotation of the drum to eliminate dirt.

In the related art, in order to seal the space of the outer tub and prevent the washing water contained in the outer tub from leaking, a rubber door seal is usually used to connect the front end opening of the outer tub to the housing, and the outer tub is formed into a sealed space by a door assembly and the rubber door seal. The outer cylinder is connected with the shell through a shock absorber and a suspension spring, the roller is arranged on the outer cylinder through a main shaft on the roller and a bearing seat on the outer cylinder, and the power of the motor is transmitted to the roller through the main shaft. During washing, the outer tub will produce certain amount of axial and radial displacement due to the vibration of the machine. The roller motion is mainly the motion of rotating around the main shaft, and simultaneously comprises the vibration displacement along with the outer cylinder. Because the outer cylinder can produce certain displacement when vibrating, in order to prevent the door seal connected with the outer cylinder from being damaged and prevent the connecting part from loosening, the door seal is usually designed to be provided with a fold line structure.
