Abstract

A support for household appliance comprises a hydraulic plate internally provided with a liquid flow passage, a sheath fixedly connected with the hydraulic plate, a regulating support arranged in the sheath and axially movable relative to the sheath, an accommodation chamber is formed by the hydraulic plate, the sheath and the regulating support. A flexible accommodation body that accommodates a liquid medium in the accommodation chamber extends and retracts to drive the regulating support to move in the sheath for leveling under the action of pressure. The flexible accommodation body is provided with an mounted on the hydraulic plate through the sheath in a sealed manner and communicates with the a liquid flow passage. The hydraulic medium in the flexible accommodation body can circulate into the liquid flow passage and flow to the liquid outlet nozzle through the a liquid flow passage, and thus, among household-appliance-used bottom feet for automatic leveling.

Claims

1. A support for a household appliance, comprising:

a hydraulic plate being internally provided with a liquid flow passage;

a sheath being fixedly connected with the hydraulic plate;

a regulating support 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 support; and

a flexible accommodation body accommodating a liquid medium and being arranged in the accommodation chamber;

the flexible accommodation body extending and retracting to drive the regulating support to axially move in the sheath for leveling under an action of pressure;

wherein the flexible accommodation body is provided an opening part, and the opening part is mounted on the hydraulic plate through the sheath in a sealed manner and communicates with the liquid flow passage.

2. The support for the household appliance according to claim 1, wherein an upper end of the sheath is fixedly connected with the hydraulic plate and tightly presses the opening part of the flexible accommodation body onto the hydraulic plate for sealed connection.

3. The support for the household appliance according to claim 1, wherein an upper end of the sheath is flanged to form a mounting plane, the mounting plane is fit with a bottom face of the hydraulic plate and is in fastened connection with the bottom face of the hydraulic plate through a connecting device, and the opening part of the flexible accommodation body is tightly pressed to the mounting plane and the bottom face of the hydraulic plate for sealed connection.

4. The support for the household appliance according to claim 1, wherein the flexible accommodation body comprises an accommodating body, a chamber used for accommodating the liquid medium is formed inside the accommodating body, an opening end of the accommodating body outwards extends to form the opening part;

and the accommodating body is arranged in the accommodation chamber, and the opening part extends into a connection part of the sheath and the hydraulic plate and is tightly sealed.

5. The support for the household appliance according to claim 1, wherein a hydraulic plate groove is formed in the bottom face of the hydraulic plate, and the opening part of the flexible accommodation body is deformed under pressure of an end part of the sheath and fills in the hydraulic plate groove for sealing.

6. The support for the household appliance according to claim 5, wherein a sheath projecting part bulges from an end face of one end, connected with the hydraulic plate, of the sheath, and the opening part of the flexible accommodation body is deformed under pressure of the sheath projecting part and fills the hydraulic plate groove for sealing.

7. The support for the household appliance according to claim 1, wherein a sheath groove is formed in an end part of one end, connected with the hydraulic plate, of the sheath;

the sheath is fastened to the bottom face of the hydraulic plate, and the opening part of the flexible accommodation body deforms and fills the sheath groove for sealing.

8. The support for the household appliance according to claim 7, wherein a projecting annular bulge is formed on the bottom face of the hydraulic plate, the sheath is fixed to the bottom face of the hydraulic plate, and the opening part of the flexible accommodation body is deformed under pressure of the annular bulge and fills the sheath groove for sealing.

9. The support for the household appliance according to claim 1, wherein an upper limiting stopper, which is used for preventing the regulating support from excessively moving upwards to be abutted against the flexible accommodation body, is arranged on an internal wall of the sheath;

and/or, one end, sleeved by the sheath, of the regulating support is a smooth transition end.

10. A household appliance with the support for household appliance according to claim 1.

11. The support for the household appliance according to claim 2, wherein the upper end of the sheath is flanged to form a mounting plane, the mounting plane is fit with a bottom face of the hydraulic plate and is in fastened connection with the bottom face of the hydraulic plate through a connecting device, and the opening part of the flexible accommodation body is tightly pressed to the mounting plane and the bottom face of the hydraulic plate for sealed connection.

12. The support for the household appliance according to claim 2, wherein the flexible accommodation body comprises an accommodating body, a chamber used for accommodating the liquid medium is formed inside the accommodating body, an opening end of the accommodating body outwards extends to form the opening part;

and the accommodating body is arranged in the accommodation chamber, and the opening part extends into a connection part of the sheath and the hydraulic plate and is tightly sealed.

13. The support for the household appliance according to claim 5, wherein a volume enclosed by the end part of the sheath and the hydraulic plate groove is smaller than a volume of the opening part of the flexible accommodation body.

14. The support for the household appliance according to claim 2, wherein a hydraulic plate groove is formed in the bottom face of the hydraulic plate, and the opening part of the flexible accommodation body is deformed under pressure of an end part of the sheath and fills in the hydraulic plate groove for sealing.
