Abstract

A support for household appliance includes 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 and the sheath can be rapidly, reliably and fixedly connected, the requirements on the strength of connection between the hydraulic plate and the sheath are lowered, and the essential space and height required by the connection are further lowered.

First claim

The invention claimed is:

1. A support for a household appliance, comprising
a hydraulic plate being fixed to a bottom of the household appliance;
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; 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
the sheath and the hydraulic plate are fixedly mounted at the bottom of the household appliance through a connecting device and the hydraulic plate is clamped between a mounting plane of the sheath and the bottom of the household appliance.

2. The support for the household appliance according to claim 1 , wherein an upper end of the sheath is flanged outward to form the 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.

3. The support for the household appliance according to claim 2 , wherein an outline of the mounting plane is matched with an outline of the hydraulic plate, and the mounting plane is fit with the bottom face of the hydraulic plate and is fixedly connected with the bottom face of the hydraulic plate.

4. The support for the household appliance according to claim 3 , wherein the outline of the hydraulic plate is similar to or the same as the outline of the mounting plane.

5. The support for the household appliance according to claim 2 , wherein the sheath comprises a sleeve part which is internal hollow, 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 the mounting plane, and the mounting plane is fit with the bottom face of the hydraulic plate and is fixedly connected with the bottom face of the hydraulic plate.

6. The support for the household appliance according to claim 2 , wherein the sheath and the hydraulic plate are fixedly mounted at the bottom of the household appliance through a connecting device and the hydraulic plate is clamped between the mounting plane of the sheath and the bottom of the household appliance.

7. The support for the household appliance according to claim 1 , wherein the sheath comprises a sleeve part which is internally hollow, 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 the 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.

8. The support for the household appliance according to claim 7 , wherein the hydraulic plate is of a square flat-plate structure, the sleeve part is of a cylindrical structure, an outward flanging of an upper end of the cylindrical structure forms the mounting plane which is square in shape and matched with the hydraulic plate, and the flat-plate structure is fit with the square mounting plane and is fixedly connected with the mounting plane.

9. The support for the household appliance according to claim 1 , wherein the bottom of the household appliance is provided with a mounting hole, a hydraulic plate hole is formed in the hydraulic plate, and a sheath hole is formed in the sheath;
the connecting device is a connecting bolt/connecting screw, and the connecting bolt/connecting screw sequentially penetrates through the sheath hole and the hydraulic plate hole and is fastened to the mounting hole.

10. The support for the household appliance according to claim 9 , wherein a plurality of the sheath holes are uniformly distributed along a circumferential direction of the mounting plane, a plurality of the hydraulic plate holes are uniformly distributed along a circumferential direction of the hydraulic plate, and the mounting holes are formed in the bottom plate of the household appliance corresponding to the plurality of hydraulic plate holes and the plurality of sheath holes.

11. The support for the household appliance according to claim 9 , wherein at least two mounting holes, at least two hydraulic plate holes and at least two sheath holes are formed.

12. The support for the household appliance according to claim 9 , wherein four mounting holes, four hydraulic plate holes and four sheath holes are formed.

13. The support for the household appliance according to claim 1 , wherein the sheath and the hydraulic plate are fixedly connected in a snap-in connection, a bonding, a hot-melting or a welding manner.

14. The support for the household appliance according to claim 1 , wherein the hydraulic plate is made of plastics through integral injection molding or made of metal through die-casting, and the sheath is made of plastics through integral injection molding or made of a metallic material through die-casting.

15. The support for the household appliance according to claim 14 , wherein the hydraulic plate is made of plastics through integral injection molding, and the sheath is made of metal through die-casting.
