A support for household appliance comprises a hydraulic plate internally provided with a liquid flow passage, a sheath fixedly connected with the hydraulic plate, a regulating support arranged in the sheath and axially movable relative to the sheath, an accommodation chamber is formed by the hydraulic plate, the sheath and the regulating support. A flexible accommodation body that accommodates a liquid medium in the accommodation chamber extends and retracts to drive the regulating support to move in the sheath for leveling under the action of pressure. The flexible accommodation body is provided with an mounted on the hydraulic plate through the sheath in a sealed manner and communicates with the a liquid flow passage. The hydraulic medium in the flexible accommodation body can circulate into the liquid flow passage and flow to the liquid outlet nozzle through the a liquid flow passage, and thus, among household-appliance-used bottom feet for automatic leveling.
