Abstract

The present disclosure provides a support for household appliance and a household appliance, the support for household appliance comprises a hydraulic plate, which is fixed to the bottom of the household appliance; a sheath, which is fixedly connected with the hydraulic plate; a regulating support, 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 support; and a flexible accommodation body, which accommodates a liquid medium and is arranged in the accommodation chamber. The flexible accommodation body extends and retracts to drive the regulating support to axially move in the sheath for leveling under the action of pressure. The hydraulic plate is locally embedded inside the sheath, thus, the overall height of the support for household appliance is reduced while the overall strength of the hydraulic plate is guaranteed.

First claim

The invention claimed is:

an accommodation chamber formed by the hydraulic plate, the sheath and the regulating support; and
a flexible accommodation body accommodating a liquid medium and arranged in the accommodation chamber; wherein
the flexible accommodation body extends and retracts to drive the regulating support to axially move in the sheath for leveling under an action of pressure; and wherein,
the hydraulic plate is locally embedded inside the sheath.

2. The support for the household appliance according to claim 1 , wherein a bulging embedding part is arranged on a surface, facing to the sheath, of the hydraulic plate and is embedded inside the sheath.

3. The support for the household appliance according to claim 2 , wherein the sheath comprises a sleeve part which is internally hollow, and one end of the regulating support is sleeved by the sleeve part and is axially movable relatively;
an upper end of the sleeve part is flanged outward to form a mounting plane, and the mounting plane is fit with a bottom face of the hydraulic plate and is fixedly connected with the bottom face of the hydraulic plate; and the embedding part is embedded inside the sleeve part.

4. The support for the household appliance according to claim 3 , wherein the hydraulic plate comprises a square plate body, the sleeve part is of a cylindrical structure, an outward flanging of an upper end of the cylindrical structure forms a square mounting plane which is matched with the hydraulic plate, and the square plate body is fit with the square mounting plane and is fixedly connected with the square mounting plane;
and the embedding part is a cylindrical bulge which bulges from a surface of the square plate body, and the cylindrical bulge is embedded inside the cylindrical structure.

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

6. The support for the household appliance according to claim 5 , wherein the embedding part comprises a first embedding part bulging from a plane of the hydraulic plate and a second embedding part bulging from a plane of the first embedding part;
the pressing ring comprises a radial projecting part, an inner diameter of the radial projecting part is smaller than an outer diameter of the opening part of the flexible accommodation body, the pressing ring is fixed to a bottom face of the first embedding part, and the opening part of the flexible accommodation body is deformed under pressure of the radial projecting part and fills the hydraulic plate groove for sealing.

7. The support for the household appliance according to claim 1 , wherein the hydraulic plate comprises a liquid outlet nozzle, and a liquid flow passage is formed inside the hydraulic plate and communicates with the liquid outlet nozzle and an interior of the flexible accommodation body; and the liquid outlet nozzle is arranged in a manner of being lower than an upper plane of the hydraulic plate.

8. The support for the household appliance according to claim 7 , wherein a base part is projected and formed on the bottom face of the hydraulic plate, and the liquid outlet nozzle is arranged on the base part.

9. The support for the household appliance according to claim 7 , wherein a liquid nozzle outlet which is used for yielding a mounting of the liquid outlet nozzle is formed in the sheath.

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

11. The support for the household appliance according to claim 5 , wherein the hydraulic plate groove is formed in an end face of the embedding part.

12. The support for the household appliance according to claim 2 , wherein a hydraulic plate groove is formed in an end face of a part, embedded inside the sheath, of the hydraulic plate;
the flexible accommodation body is provided with an opening part, and the opening part of the flexible accommodation body is deformed under pressure of a pressing ring and fills the hydraulic plate groove for sealing.

13. The support for the household appliance according to claim 3 , wherein a hydraulic plate groove is formed in an end face of a part, embedded inside the sheath, of the hydraulic plate;
the flexible accommodation body is provided with an opening part, and the opening part of the flexible accommodation body is deformed under pressure of a pressing ring and fills the hydraulic plate groove for sealing.

14. The support for the household appliance according to claim 8 , wherein the projecting base part and the embedding part are arranged in a same level and are interconnected.

15. The support for the household appliance according to claim 9 , wherein openings which communicate with each other are correspondingly formed in the mounting plane and the sleeve part respectively to form the liquid nozzle outlet, and the base part is embedded in the liquid nozzle outlet for yielding mounting of the liquid outlet nozzle.

16. The support for the household appliance according to claim 8 , wherein a liquid nozzle outlet which is used for yielding a mounting of the liquid outlet nozzle is formed in the sheath.
