Problems solved by technology

[0004] Although the feet of the above-mentioned washing machine realize the leveling of the washing machine, the user needs to manually adjust it. If the washing machine has a large weight or the installation space is small, the user's operation is inconvenient
In addition, the vibration of the washing machine during the long-term working process also has an effect on the leveling feet, which can easily lead to the failure of its support and cause the washing machine to be placed unevenly.
[0005] For example, the existing 8KG drum washing machine is generally about 80Kg, which is relatively heavy, and it is extremely inconvenient for consumers to adjust. Even if the adjustment is completed, the washing machine cannot be adjusted to the best state. The washing machine is accelerated from 0r / min to about 1600r / min when washing. During drying and dehydration, once the washing machine is not level or there is a problem with weak legs, it will cause great vibration, which greatly affects the comfort of consumers
[0006] The vibration caused by the unevenness of the washing machine may loosen the foot screws, allowing the foot brackets to move vertically, this instability may change the level of the washing machine, resulting in stronger vibrations
This vicious cycle makes the washing machine use for a long time, the noise will become louder, and it will also cause some damage to the washing machine itself, shortening the service life.
[0007] Therefore, the leveling of the existing washing machine requires manual adjustment, which is time-consuming, laborious and has poor precision.

Embodiment 1

[0039] like Figure 1-Figure 2 As shown, a leveling device of this embodiment is used for supporting and leveling household appliances, and includes an adjustment foot 100, and the adjustment foot 100 includes:

[0040] The fixing part is installed on the bottom of the household appliance;

[0041] The movable adjustment part is sheathed with the fixed part and can move axially relative to it, and there is an accommodation chamber between the movable adjustment part and the fixed part;

[0042] A phase change material medium 102 is arranged in the containing chamber;

[0043] At least two adjusting feet 100 communicate with each other through the communication device 200, wherein at least one of the adjusting feet 100 and / or the communication device is provided with a heating device 300;

[0044] The heating device 300 heats the phase change material medium 102, and the phase change material medium 102 turns into a liquid state, flows between the adjustment feet 100 and driv...

Embodiment 2

[0076] This embodiment provides a washing machine with a leveling device as described in Embodiment 1, which includes a housing, a plurality of leveling feet are installed on the bottom of the housing, and the phase change material medium filled inside the leveling feet is in a liquid state. It can be circulated between the leveling feet for leveling;

[0077] Preferably, the housing is evenly arranged along the circumference of the bottom of the housing, and the feet of the household appliances are connected to each other, or all the feet of the household appliances are connected to each other, and the liquid phase change material medium can Leveling by circulation between the feet of interconnected household appliances.

[0078] Further, the washing machine in this embodiment further includes a controller, the heating device is electrically connected to the controller, and the controller controls whether the heating device is heated.

[0079] The leveling device in this emb...

Embodiment 3

[0085]This embodiment provides a washing machine control method as described in Embodiment 3. The washing machine starts the automatic leveling program, controls the heating device to be powered on and heated, and the phase change material medium is transformed into a liquid state under the heating of the heating device. The phase change material medium flows between the leveling feet to automatically adjust the height until the pressure of each leveling foot is balanced, and the automatic leveling is completed;

[0086] After the washing machine detects that the automatic leveling is completed, it controls the heating device to cut off the power, and the phase change material medium turns into a solid state, maintaining the rigid support of the leveling state.

[0087] Further, the washing machine controls the heating device to heat for a certain period of time, and judges whether the washing machine has reached a pressure balance state through the pressure sensor. If the judg...

Abstract

The invention provides a leveling device, a washing machine with the leveling device and a control method of the washing machine with the leveling device. The leveling device is used for supporting and leveling of a household appliance and comprises adjusting bottom feet; the adjusting bottom feet comprise fixed parts, movable adjusting parts and phase-change material media, wherein the fixed parts are arranged at the bottom of the household appliance, the movable adjusting parts sleeve the fixed parts and can move axially relative to the fixed parts, containing cavities are formed between themovable adjusting parts and the fixed parts, and the phase-change material media are arranged in the containing cavities; at least two adjusting bottom feet communicate with each other through a communicating device, wherein at least one adjusting bottom foot and / or the communicating devices are provided with heating devices correspondingly; the heating devices are used for heating the phase-change material media, the phase-change material media are converted into liquid, and the liquid flows among the adjusting bottom feet and drives the movable adjusting parts to move axially so as to carryout leveling under the action of pressure; and when the heating devices stop heating, the phase-change material media are converted into solid, and the rigid support in a leveling state is kept.

Description

technical field [0001] The invention relates to the technical field of support and leveling of household appliances, in particular to a leveling device, a washing machine with the leveling device and a control method thereof. Background technique [0002] Household appliances are generally equipped with a leveling device at the bottom of the shell. When placing the household appliance, the leveling device can be adjusted to make it reach a stable placement state. After leveling and placing, the leveling device can support the household appliance to keep it Stablize. [0003] Taking the washing machine as an example, the existing washing machines are generally equipped with bolt feet at the bottom of the shell or the whole machine. The bolt feet include screw rods, nut washers and rubber pads. The nut washers can be rotated up and down on the screw rods, and the screw rods can also be Rotate up and down in the screw hole of the bottom plate of the shell, and adjust the heigh...
