Abstract

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; an overall height h and a transverse length D of the support for household appliance are determined by specification parameters of a household appliance with the foot. The range defined in the embodiment of the support for household appliance can meet the leveling requirements of household appliances.

First claim

The invention claimed is:

1. A support for household appliance, comprising:
a hydraulic plate;
a sheath, fixedly connected with the hydraulic plate;
a regulating element arranged in the sheath and configured to be axially movable relative to the sheath, the regulating element configured to be driven by a hydraulic medium; and
an accommodation chamber formed by the hydraulic plate, the sheath and the regulating element for containing the hydraulic medium;
wherein the hydraulic plate includes a first mounting hole and a second mounting hole, the hydraulic plate configured to be fixedly connected to a bottom plate of a household appliance in a manner that a first connecting member passes through the first mounting hole, and the hydraulic plate is fixedly connected with the sheath in a manner that a second connecting member passes through the second mounting hole,
an upper end of the sheath is flanged to form a mounting plane, and the mounting plane is fit with a bottom surface of the hydraulic plate and is fixedly connected with the bottom surface of the hydraulic plate, and
an overall height h and a transverse length D of the support for household appliance and a weight m of the household appliance have a relationship: h/D is inversely proportional to m.

2. The support for household appliance according to claim 1 , wherein the overall height h of the support for household appliance is a sum of a height of the regulating element and a height of the sheath when the regulating element completely stretches out from the sheath.

3. The support for household appliance according to claim 1 , wherein a main body of the sheath is of a cylindrical structure, and the regulating element is sleeved in the cylindrical structure and is axially movable, and the transverse length D of the support for household appliance is a diameter of the sheath.

4. The support for household appliance according to claim 3 , wherein the regulating element is of a cylindrical structure, and a diameter d of the regulating element meets: 5 mm≤d≤590 mm.

5. The support for household appliance according to claim 1 , wherein the overall height h and the transverse length D of the support for household appliance meet: 0<h/D≤10.

6. The support for household appliance according to claim 1 , wherein at least two supports for household appliance communicate with each other through hydraulic pipes so as to allow the hydraulic medium to flow between the supports; and a diameter d1 of each hydraulic pipe meets: 0.5 mm≤d1≤h.

7. The support for household appliance according to claim 6 , wherein the two supports for household appliance communicate with each other through a hydraulic pipe to form a supports group for household appliance, and an overall length of the supports group for household appliance is not smaller than the width of the household appliance.

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

9. The household appliance according to claim 8 , wherein the household appliance is a washing machine, and the overall height h and the transverse length D of the support for household appliance and a capacity V of the washing machine have a relationship: h/D is inversely proportional to the V.

10. The support for household appliance according to claim 2 , wherein the overall height h of the support for household appliance meets: 5 mm≤h≤100 mm.

11. The support for household appliance according to claim 10 , wherein the overall height h of the support for household appliance is 25±15 mm.

12. The support for household appliance according to claim 3 , wherein the transverse length D of the support for household appliance meets: 5 mm≤D≤590 mm.

13. The support for household appliance according to claim 12 , wherein the transverse length D of the support for household appliance is 50±30 mm.

14. The support for household appliance according to claim 4 , wherein the diameter d of the regulating element is 50±30 mm.

15. The support for household appliance according to claim 5 , wherein the overall height h and the transverse length D of the support for household appliance meet: 0.1≤h/D≤1.

16. The support for household appliance according to claim 15 , wherein the overall height h and the transverse length D of the support for household appliance meet: 0.4≤h/D≤0.8.

17. The support for household appliance according to claim 6 , wherein a diameter d1 of each hydraulic pipe is 10±9 mm.

18. The support household appliance according to claim 1 , comprising:
the hydraulic medium, the hydraulic medium being compressible/expandable depending on pressure changes.
