HORINZONTAL CONTROL DEVICE OF A WASHING MACHINE

摘要

A leveling device for washers is disclosed for adjusting the horizontal level and preventing noise. The device has a leveling device (4) attached on the exterior frame (1) by the opening of a choke valve (44) fitted to an oil pipe (42) of the leveling device (4). When the floor is sloped, the oil reversely flows into the oil reservoir (41) and pushes a piston (45) in a cylinder (43) through the oil pipe (42). The base plate (46) fitted on the piston contacts the floor and elevates the exterior frame (1) of the washing machine as the piston actuates downwardly. Then the oil pressure of the cylinder (43) from the oil reservoir (41) equalizes to regulate the level. When the leveling is finished, the oil pipe (42) is shut off by closing the choke valve (44) to prevent oil reversing and pressure change.
