LEVELING DEVICE FOR HOUSEHOLD APPLIANCE AND HOUSEHOLD APPLIANCE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2018/006561
Kind Code:
A1
Abstract:
Provided are a leveling device for a household appliance and a household appliance having same. The leveling device comprises at least two leveling foot members (100, 300) attached to the bottom of a household appliance. The leveling foot members (100, 300) comprise fixing members (102, 302) and movable members (101, 301). The fixing members are attached to the bottom of the household appliance. The movable member has one end retractably sleeved into the interior or onto the exterior of the fixing member and the other end disposed at a supporting surface. A closed cavity is arranged between the fixing member and the movable member. A hydraulic medium (400) is filled in the closed cavity. The closed cavities of the at least two leveling foot members mutually communicate by means of a high-pressure oil pipe (200). The hydraulic medium can flow between the mutually communicated closed cavities of the leveling foot members. Flowing of the hydraulic medium causes the movable members to extend or retract so as to perform automatic leveling. Areas of acting surfaces in contact with the hydraulic medium in the respective leveling foot members mutually communicated by the high-pressure oil pipe can be the same or different. The leveling device for a household appliance is applicable to a household appliance in which the center of gravity and the geometrical center do not coincide. After leveling, the respective leveling foot members uniformly bear forces acting thereon.
