This stored force allows the body to be suspended from the stationary frame and thus provides a supporting load to the main body 100. When the washing and dehydrating machine body 100 rotates, centrifugal force is generated to swing the machine body up and down, and the force generated by the up-and-down swing is transmitted to the pull rod 440, so that the spring 420 is deformed to generate a certain acting force. The heave oscillation of the body is stopped by the resilience of the spring 420, which has a damping effect and evolves into a damping force. The damping force generated by the supporting damping member 400 can reduce the swing amplitude of the body, thereby achieving the damping effect.
