Abstract

The present disclosure discloses a support for household appliance and a household appliance. The support for household appliance comprises a fixed part and a moving part, a hollow chamber is formed between the fixed part and the moving part and the hollow chamber is provided with a hydraulic medium. At least two household-appliance-used supports communicate with one another through high-pressure pipes; and the hydraulic medium circulates among the household-appliance-used supports under action of pressure to drive the moving part to extend and retract to achieve automatic leveling. Liquid outlet nozzles communicating with the hollow chamber are arranged on the fixed part, the high-pressure pipes are in sealed connection with the liquid outlet nozzles through snap-in connecting members, and the snap-in connecting members have reinforcing aprons which are fit with the fixed part. In the present disclosure, the hydraulic medium circulates between the two supports for the household appliance for automatic leveling.
