摘要： A household appliance foot (100) and a household appliance are provided. The household appliance foot comprises a hydraulic plate (101); a sheath (103), being fixedly connected with the hydraulic plate; a regulating foot (104), being arranged in the sheath and being axially movable relative to the sheath; an accommodation chamber, being formed by the hydraulic plate, the sheath and the regulating foot; a hydraulic medium (102), being in the accommodation chamber and being compressed or expanding with pressure changes to drive the regulating foot to axially move in the sheath for leveling; a communicating device, communicating at least two household appliance feet for allowing the hydraulic medium to flow between the household appliance feet; and a throttling structure (300, 500), being arranged in the communicating device for slowing down a flow velocity of the hydraulic medium. The throttling structures are arranged in the communicating devices, so that the rapid flowing of the hydraulic medium among the household appliance feet is prevented, and a regulating process can be more stable. In addition, in view of the condition that pressure of the household appliance feet changes greatly, the throttling structures can cushion well.

摘要： A support for washing machine with automatic leveling function and a washing machine are provided. The support for washing machine comprises: a sheath (500); a regulating mechanism (300), which is arranged in the sheath (500) and is axially movable relative to the sheath; and a flexible body assembly (200), which is arranged in the regulating mechanism (300) and accommodates a hydraulic medium. One end of the flexible body assembly (200) is limited and arranged in the sheath (500), another end is a stretchable end which acts on the regulating mechanism (300). The stretchable end expands and contracts under the action of the hydraulic medium and drives the regulating mechanism (300) to move axially for automatic leveling. The flexible body assembly (200) comprises a flexible accommodating body, a mounting assembly for mounting the flexible accommodating body, and a protection mechanism provided between the mounting assembly and the flexible accommodating body for protecting the flexible accommodating body. The flexible body assembly (200) is limited and arranged in the sheath (500) to avoid any damage to the flexible body assembly (200). In addition, the arrangement of the protection mechanism avoids the flexible accommodating body from directly contacting with the mounting assembly which greatly reduces the chance of breakage of the flexible accommodating body and extends the service life.

摘要： A washing machine leg (800) with automatic leveling function and a washing machine are provided. The washing machine leg (800) comprises: a jacket (500); an adjusting leg (300), which is arranged in the jacket (500) and moves axially relative to the jacket; and a flexible assembly (200), which is arranged in the adjusting leg (300) and is used for accommodating a hydraulic medium. One end of the flexible assembly (200) is mounted in the jacket (500) in a limiting manner, and another end of the flexible assembly (200) is a telescopic end acting on the adjusting leg (300). The telescopic end of the flexible assembly (200) extends and contracts under action of the hydraulic medium to drive the adjusting leg (300) to move axially, thereby implementing automatic leveling. According to the hydraulic principle, the washing machine leg (800) is provided with the hydraulic medium, the washing machine feet can automatically adjust adaptively for different pressures due to the fluidity of the hydraulic medium, and the hydraulic medium is contained in the sealed flexible assembly (200), and the flexible assembly is arranged inside the adjusting leg (300) to effectively solve the problem of the leakage of the hydraulic medium and ensure the stability of the work of the washing machine feet.

摘要： The present disclosure provides a support for household appliance and a household appliance. The support for household appliance comprises a hydraulic plate; a sheath, which is fixedly connected with the hydraulic plate; a regulating element, 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 element; a hydraulic medium, which is arranged in the accommodation chamber and is compressed/expands depending on pressure changes to drive the regulating element to axially move in the sheath for leveling; at least two supports for household appliance communicate with each other to allow the hydraulic medium to flow between the supports; and the hydraulic plate is provided with a one-way flow stop mechanism for conducting the hydraulic medium in one direction. When the support for household appliance is subjected to a large impact and the hydraulic medium flows to a direction that does not conform to the conduction direction of the one-way flow stop mechanism, the one-way flow stop mechanism prevents the sudden flow of the hydraulic medium from causing a sudden expansion and contraction of the support for household appliance, and that improves the stability and service life of household appliances.
