A support for household appliance includes a hydraulic plate which is fixed to the bottom of the household appliance; a sheath, which is fixedly connected with the hydraulic plate; a regulating support, 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 support; and a flexible accommodation body, which accommodates a liquid medium and is arranged in the accommodation chamber. The flexible accommodation body extends and retracts to drive the regulating support to axially move in the sheath for leveling under the action of pressure. The hydraulic plate and the sheath can be rapidly, reliably and fixedly connected, the requirements on the strength of connection between the hydraulic plate and the sheath are lowered, and the essential space and height required by the connection are further lowered.

An elevation device includes a mounting frame, a rotary actuator fixed to the mounting frame, a shaft connected to the rotary actuator and rotatable with respect to the mounting frame, a drive bar slidably connected to the mounting frame, and a connecting member fixed to the shaft. The shaft defines a helical groove in a lateral surface thereof. The drive bar includes a post that is movably fit in the helical groove. The mounting frame, the shaft and the drive bar constitute a conversion mechanism that converts rotation of the shaft into linear motion of the drive bar. The drive bar is slidable with respect to the mounting frame along a direction that is parallel to an axis of rotation of the shaft.

A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.
