Abstract
The bottom of a washing machine is provided with feet that compromise a fixed part and a movable part, and a hollow chamber is formed between the fixed part and the movable part. The hollow chamber is provided with a hydraulic medium. The feet are connected by high-pressure oil pipes, to communicate hollow chambers of the feet. Under the action of pressure, the hydraulic medium can be circulated between hollow chambers of connected feet to realize the expansion and contraction of the movable part, to execute automatic leveling. Under different pressures, the foot is made to automatically adjust adaptively due to the fluidity of the hydraulic medium. The hydraulic medium can flow between the feet, so the adjusting range is larger and can achieve better results.
