The present disclosure provides a support for household appliance and a household appliance. The support for household appliance comprises a hydraulic plate; a sheath, which is fixedly connected with the hydraulic plate; a regulating element, which is arranged in the sheath and is axially movable relative to the sheath; an accommodation chamber, which is formed by the hydraulic plate, the sheath and the regulating element; a hydraulic medium, which is arranged in the accommodation chamber and is compressed/expands depending on pressure changes to drive the regulating element to axially move in the sheath for leveling; at least two supports for household appliance communicate with each other to allow the hydraulic medium to flow between the supports; and the hydraulic plate is provided with a one-way flow stop mechanism for conducting the hydraulic medium in one direction. When the support for household appliance is subjected to a large impact and the hydraulic medium flows to a direction that does not conform to the conduction direction of the one-way flow stop mechanism, the one-way flow stop mechanism prevents the sudden flow of the hydraulic medium from causing a sudden expansion and contraction of the support for household appliance, and that improves the stability and service life of household appliances.
