Title:
WASHING MACHINE HAVING AUTOMATIC LEVELING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/049755
Kind Code:
A1
Abstract:
A washing machine having an automatic leveling function. Fixed feet (1000) and a hydraulic foot (800) are separately provided at the bottom of the washing machine. At least two fixed feet (1000) and at least one foot (800) constitute a support plane for supporting the washing machine. The hydraulic foot (800) comprises a fixed part and a movable part, and a hollow cavity (301) is formed between the fixed part and the movable part. The hollow cavity (301) is filled with a hydraulic medium. The hydraulic medium can flow, under pressure, inside the hollow cavity (301) of the hydraulic foot (800) and/or between hollow cavities (301) of the hydraulic feet (800), so as to drive the movable part to stretch and retract. The hydraulic foot (800) and the fixed feet (1000) can work in concert to implement automatic leveling. On the basis of the fundamental principle of determining a plane by using three points, at least two fixed feet (1000) determine two points, and the hydraulic foot (800) determines the other point, so as to ensure that even on uneven ground, the fixed feet (1000) withstand gravity and the hydraulic foot (800) automatically stretches or retracts according to the pressure, thereby implementing automatic leveling of the washing machine.
