Leveling device, washing machine with leveling device and control method of washing machine with leveling device

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...

AI Technical Summary

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.
