  • Patent number: 10801578
    Abstract: A household appliance foot comprises a hydraulic plate; a sheath, which is fixedly connected with the hydraulic plate; a regulating foot, 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 foot; and a hydraulic medium, which is arranged in the accommodation chamber and is compressed or expands with pressure changes to drive the regulating foot to axially move in the sheath for leveling. Based on the hydraulic principle, the regulating foot can perform adaptive regulation automatically because of the fluidity of the hydraulic medium due to different pressures resulting from unflatness, the hydraulic medium stops circulating until the household appliance foot achieves balance, and automatic leveling is achieved.

  • Patent number: 10704188
    Abstract: An automatic leveling washing machine includes a shell and a barrel assembly. A bottom plate of the shell has leveling bottom feet with hydraulic medium therein and hydraulic medium flows between leveling bottom feet to execute automatic leveling washing machine. The bottom plate of the shell has mounting grooves for fixing and mounting leveling bottom feet. Hydraulic medium and some gas flows inside each leveling bottom foot or between leveling bottom feet. The amount of compression of the leveling bottom foot which is under bigger pressure is big, and the amount of compression of the leveling bottom foot which is under smaller pressure can still stretch, thereby automatically realizing the leveling of the height. The mounting groove effectively and quickly positions the leveling bottom feet. A circumferential surface of the mounting groove protects the leveling bottom feet and allows high reliability of operation.

  • Publication number: 20200173095
    Abstract: A support for washing machine with automatic leveling function comprises a sheath; a regulating mechanism arranged inside the sheath in an axial movable manner, whose circumferential rotation is limited by the sheath; and a flexible body inside the regulating mechanism for accommodating a hydraulic medium. The flexible body comprises a telescopic end which acts on the regulating mechanism, the telescopic end expands and contracts under an action of the hydraulic medium and drives the regulating mechanism to move axially for automatic leveling. Based on the hydraulic principle, the support can perform adaptive regulation automatically by means of the fluidity of the hydraulic medium of different pressures. Moreover, the structures of the regulating mechanism and the sheath are designed to avoid that the automatic leveling for washing machine is influenced by the regulating mechanism's rotation in inside the sheath. Thus, the automatic leveling effect is ensured.
