When the washing machine is a washing and dewatering integrated washing machine, the drum 2 is a drum for washing and dewatering by the washing machine, and when the washing machine is a washing and dewatering separated washing machine, the drum 2 is a dewatering tub for dewatering laundry.

The washing machines are generally classified into a drum washing machine and a pulsator washing machine, the drum washing machine is generally a washing and dewatering integrated washing machine, and a drum shaft of the drum washing machine is generally horizontally arranged or arranged at a certain inclination angle with the horizontal. Pulsator washing machines are classified into washing and dehydrating integrated washing machines and washing machines in which washing and dehydrating are performed separately, and a drum axis of the pulsator washing machine is generally vertically disposed. The description of the washing machine in the present embodiment is based on the drum washing machine, and when the laundry device 3 is provided in the pulsator washing machine, the corresponding setting may be made with reference to the setting of the laundry device 3 in the drum washing machine.

As shown in fig. 1, the washing machine includes a housing 1 having a cavity, one side of the housing 1 has an opening, and the housing 1 is hinged with a door 11 at the opening for opening or closing the opening. The cylinder 2 comprises an inner cylinder 21 and an outer cylinder 22, the outer cylinder 22 is used for containing water and is elastically supported in the shell 1, specifically, the front end of the outer cylinder 22 is elastically connected with the shell 1 through an elastic window pad 5, and the side part and the rear end of the outer cylinder 22 are connected with a shock absorber 7 through a spring 6 and are supported on the inner wall of the shell 1. The spring 6 and the damper 7 play a role in damping during the operation of the washing machine, so as to prevent the outer tub 21 from vibrating to a large extent during the washing or dewatering process of the laundry, attenuate the vibration, and prevent the vibration from being transmitted to the housing 1. In fig. 1, the position and number settings of the spring 6 and the damper 7 are both exemplary settings.

The inner drum 21 is used for containing washing clothes, and the inner drum 21 and the outer drum 22 are coaxially arranged. The lateral wall of the inner cylinder 21 is provided with a water permeable hole, the center of the rear end of the inner cylinder 21 is fixed with an inner cylinder shaft, the inner cylinder shaft penetrates out of the bottom of the outer cylinder 22 and is connected with the output shaft of the roller motor 4, and the fixed seat of the roller motor 4 is connected with the rear end of the outer cylinder 22 through a motor support. When the washing machine is used for washing and dewatering clothes, the inner drum 21 of the washing machine is driven by the drum motor 4 to rotate, and the outer drum 22 is kept relatively fixed under the action of elastic supporting members such as the spring 6, the shock absorber 7 and the elastic window pad 5.

In the present embodiment, the central axis of the cylindrical body 2 is disposed horizontally, and in other embodiments, the central axis of the cylindrical body 2 may be disposed obliquely to the horizontal direction. The casing 1, the drum 2, the drum motor 4, the elastic support structure of the outer drum 22 and the casing 1 of the washing machine can be arranged by referring to the structure of the existing washing machine, and the detailed description of the embodiment is omitted.
