Abstract

A control method for opening a door of a drum washing machine comprises the steps: S1, receiving a door opening instruction sent by a user; S2, judging whether a water level at a front end of a drum assembly satisfies a condition of opening the door, if yes, entering step S4, if no, entering step S3; S3, tilting the drum assembly with a tilting mechanism, and then returning to step S2; and S4, unlocking a door lock. Through a manner of lifting a front end of the drum assembly, the operation of opening the door during running is realized. In this way, the original parts of the washing machine do not need to be changed, and the drum assembly is tilted only through a driving device arranged at a lower part of the drum assembly or through a hanging spring arranged at a top part of the drum assembly.

First claim

The invention claimed is:

1. A support for a household appliance, comprising:
a hydraulic plate;
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 action of pressure;
wherein a fixing member for sealingly mounting the flexible accommodation body to the hydraulic plate and a protecting member for protecting the flexible accommodation body are provided, wherein the fixing member is embedded in the protecting member, and one end of the protecting member is provided with a protecting curved surface and the protecting curved surface is matched with an outer surface of the flexible accommodation body to prevent the flexible accommodation body from being damaged by pressure;
another end of the protecting member is provided with an insertion groove, and the fixing member is embedded in the insertion groove of the protecting member.

2. The support for the household appliance according to claim 1 , wherein at least one of the fixing member and the protecting member is provided with a limiting mechanism for limiting a circumferential rotation of the protecting member relative to the fixing member.

3. The support for the household appliance according to claim 2 , wherein a limiting protrusion is provided on an inner wall of the insertion groove of the protecting member, and a limiting recess cooperating with the limiting protrusion is provided on the fixing member.

4. The support for the household appliance according to claim 3 , wherein the flexible accommodation body comprises an opening part and a retractable accommodating body; the opening part is sealingly mounted to the hydraulic plate by the fixing member;

6. The support for the household appliance according to claim 1 , wherein the flexible accommodation body comprises an opening part and a retractable accommodating body; the opening part is sealingly mounted to the hydraulic plate by the fixing member;
the protecting member is arranged between the accommodation body and the fixing member; and the protecting curved surface cooperates with the accommodation body.

7. The support for the household appliance according to claim 6 , wherein the fixing member is a pressing ring and the pressing ring includes an annular body;
an inside of the annular body has a pressing ring opening;
the opening part of the flexible accommodation body passes through the pressing ring opening and is sealingly mounted to the hydraulic plate by the annular body;
the protecting member comprises a protecting ring, and a protecting ring opening for allowing the opening part to pass through is provided inside the protecting ring;
the insertion groove for allowing the pressing ring to be inserted is provided in one end of the protecting ring, proximate to the pressing ring, and the protecting curved surface is provided on an other end of the protecting ring, in touch with the flexible accommodation body.

8. The support for the household appliance according to claim 7 , wherein an internal wall of the insertion groove of the protecting ring is provided with at least one limiting protrusion, and an outer peripheral wall of the pressing ring is provided with a limiting recess matched with a limiting protrusion.

9. The support for the household appliance according to claim 8 , wherein the limiting protrusion has an arc-shaped limiting outer convex surface, and the limiting recess has an arc-shaped limiting inner concave surface, and the limiting outer convex surface and the limiting inner concave surface cooperate with each other.

10. The support for the household appliance according to claim 9 , wherein the flexible accommodation body comprises a small-diameter part communicating with the accommodating body; and
an inner diameter of the small-diameter part is smaller than an inner diameter of the accommodating body;
an end part of the small-diameter part is flanged to form the opening part, the fixing member sleeves on the small-diameter part to sealingly mount the opening part to the hydraulic plate;
the protecting member sleeves on the small-diameter part and is located between the accommodating body and the fixing member.

11. The support for the household appliance according to claim 8 , wherein a plurality of limiting protrusions are provided, which are respectively distributed along a circumferential direction of the internal wall of the insertion groove, and
a plurality of limiting recesses are provided, which are distributed on the outer peripheral wall of the pressing ring.

12. The support for the household appliance according to claim 8 , wherein the flexible accommodation body comprises a small-diameter part communicating with the accommodating body; and
