Abstract
A washing machine hydraulic leveling device comprises hydraulic feet, wherein each hydraulic foot comprises a fixed part and a movable part, a hollow chamber is formed between the fixed part and the movable part, and the hollow chamber is provided with a hydraulic medium; two said hydraulic feet communicate with each other through high-pressure oil pipes: the hydraulic medium flows under pressure between the hollow chambers of the hydraulic feet to drive the movable parts to extend and retract, thereby implementing automatic leveling; and the fixed parts are provided with oil nipples communicating with the hollow chambers, and the oil nipples of the two hydraulic feet are connected to a same connecting piece through the high-pressure oil pipes, thereby implementing communication between the two hydraulic feet.
