When the rotary tub and the pulsator rotate in a state that laundry and detergent are introduced into the rotary tub, the pulsator agitates wash water together with the laundry introduced into the rotary tub, thereby removing stains from the laundry.

In order to increase the washing capacity of the washing machine, a larger rotary tub is required, that is, the height or diameter of the rotary tub needs to be increased. If the rotary tub has a larger size, the tub accommodating the rotary tub and the cabinet accommodating the tub also need to be enlarged as the rotary tub increases.

The increase of the casing corresponding to the appearance of the washing machine is limited by the space of the area where the washing machine is installed. The location of the washing machine in the general user's home is limited. It is not realistic to increase the capacity of the washing bucket by adding the casing of the washing machine. For example, how Under the premise of not increasing the casing of the washing machine, increasing the capacity of the rotary tub has become a major problem for designers.

Suspended shock absorbers are generally installed between the rotating barrel and the casing to reduce the vibration of the rotating barrel, but the suspended shock absorbers are generally cable-stayed, which tends to occupy a large space between the rotating barrel and the casing. The limited space severely limits the volume of the rotary bucket.
