Abstract
A supporting and leveling device for a household appliance and a household appliance are provided, wherein the supporting and leveling device is provided with leveling bottom legs. Each of the leveling bottom legs includes a hydraulic connection piece, a connection sleeve, a flexible deformation membrane, an adjustment leg, and a hydraulic medium. An edge of the flexible deformation membrane is hermetically mounted at a joint of the hydraulic connection piece and the connection sleeve to form an accommodating chamber together with the hydraulic connection piece. The hydraulic medium is arranged in the accommodating chamber. When the leveling bottom leg is arranged on an uneven supporting surface, the adjustment leg axially moves along the connection sleeve to squeeze the flexible deformation membrane to deform, so as to change a volume of the accommodating chamber, and the hydraulic medium is stressed to act on the adjustment leg for leveling.
