Abstract

A household appliance support and a household appliance are disclosed. The household appliance support comprises: a hydraulic plate; a sheath, being fixedly connected with the hydraulic plate; a regulating foot, being arranged in the sheath and axially movable relative to the sheath and provided with a supporting end part in supportable contact with a supporting surface; an accommodation chamber, being formed by the hydraulic plate, the sheath and the regulating foot; a hydraulic medium, being accommodated in the accommodation chamber in a sealed manner, wherein under the effect of a pressure, the hydraulic medium is compressed or expanded to drive the regulating foot to move axially in the sheath for leveling; and a damping element, being embedded and mounted on the supporting end part of the regulating foot, to increase the supporting damping force between the regulating foot and the supporting surface.

First claim

The invention claimed is:

1. A household appliance support, comprising:
a hydraulic plate;
a sheath, being fixedly connected with the hydraulic plate;
a regulating foot, being arranged in the sheath, and one end of the regulating foot is arranged in the sheath and axially movable relative to the sheath, another end of the regulating foot is a supporting end part in supportable contact with a supporting surface, the regulating foot configured to move axially in the sheath for leveling;
an accommodation chamber, being formed by the hydraulic plate, the sheath and the regulating foot, the accommodation chamber configured to accommodate a hydraulic medium in a sealed manner; and
a damping element, being embedded and mounted on the supporting end part of the regulating foot, to increase a supporting damping force between the regulating foot and the supporting surface;
wherein a mounting groove is arranged on the supporting end part;
the mounting groove comprises a first mounting groove and a second mounting groove;
both the first mounting groove and the second mounting groove are concave from the supporting end part, a depth of the second mounting groove is greater than a depth of the first mounting groove; and
the damping element is provided with a first convex part and a second convex part;
both the first convex part and the second convex part protrude out of an upper surface of the damping element, a height of the second convex part is greater than a height of the first convex part; and
the first convex part is correspondingly embedded into the first mounting groove, and the second convex part is correspondingly embedded into the second mounting groove.

2. The household appliance support according to claim 1 , wherein the first mounting groove is an annular groove which takes a central axis of the supporting end part as a central axis,
the first convex part is an annular convex step which protrudes out of the upper surface of the damping element and takes a central axis of the damping element as a central axis, and
the annular convex step is matched with the annular groove; and
the second mounting groove is a circular groove which is arranged in a center area of the supporting end part,
the second convex part is a convex column structure which protrudes out of the upper surface of the damping element and is arranged in a center area of the damping element, and
the convex column structure is embedded into the circular groove.

3. The household appliance support according to claim 1 , wherein the first mounting groove is formed by setting a middle part of a bottom wall of the supporting end part to be higher than an edge of the bottom wall, and
the second mounting groove is formed by enabling a central position of the bottom wall of the supporting end part to be concave towards an inside of the regulating foot.

4. The household appliance support according to claim 3 , further comprising a flexible accommodation body with a chamber therein,
wherein the chamber of the flexible accommodation body is configured to accommodate the hydraulic medium,
the flexible accommodation body is provided with an opening part, and is mounted on the hydraulic plate in a sealed manner, and
a liquid flow passage is formed inside the hydraulic plate and communicated with the chamber of the flexible accommodation body so the hydraulic medium can flow between the flexible accommodation body and the liquid flow channel, to drive the regulating foot to move axially in the sheath for leveling; and
an evading part is arranged, corresponding to the second mounting groove of the regulating foot, on the flexible accommodation body.

5. The household appliance support according to claim 4 , wherein the flexible accommodation body comprises an accommodating body which is stretchable,
the opening part is a thin-diameter structure which is communicated with the accommodation body,
the accommodation body is arranged inside the regulating foot, and
one end, in contact with an inner wall of the supporting end part, of the accommodation body is partially concave corresponding to the second mounting groove to form the evading part.

6. The household appliance support according to claim 4 , wherein a surface of one end of the hydraulic plate is provided with a mounting convex column,
the opening part of the flexible accommodation body covers the mounting convex column and is mounted on the hydraulic plate in a sealed manner, and
an end part of the mounting convex column is provided with a groove.

7. The hydraulic appliance support according to claim 4 , comprising a hydraulic medium, wherein the hydraulic medium is compressible and expandable to drive the regulating foot to move axially in the sheath for levelling.

8. A household appliance with the household appliance support according to claim 1 .

9. The household appliance according to claim 8 , comprising a hydraulic medium, wherein the hydraulic medium is compressible and expandable to drive the regulating foot to move axially in the sheath for levelling.

10. The household appliance support according to claim 1 , comprising a hydraulic medium, wherein the hydraulic medium is compressible and expandable to drive the regulating foot to move axially in the sheath for levelling.
