The bottom of a household appliance is provided with leveling feet. The leveling foot comprises 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. Under the action of pressure, the hydraulic medium can be circulated in the hollow chamber inside the leveling foot and/or the hollow chamber between leveling feet to realize the expansion and contraction of the movable part, to execute automatic leveling. The leveling device of a household appliance of the present disclosure, according to the hydraulic principle, is provided with a hydraulic medium in the leveling foot. Under different pressures, the leveling foot is made to automatically adjust adaptively due to the fluidity of the hydraulic medium.
