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 1400r / min for washing. When drying and dehydrating, 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] Also, the vibration caused by the unevenness of the washing machine may loosen the foot screws, causing the foot bracket to move vertically, this instability may change the level of the washing machine, resulting in stronger vibration
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.

Abstract

The invention provides a household electrical appliance and a foot of the household electrical appliance. The foot comprises a protective sleeve which is fixed at the bottom of the household electrical appliance, an adjusting foot which is arranged in the protective sleeve and capable of moving relative to the axial direction of the protective sleeve, a flexible body assembly in which a hydraulicmedium is contained, wherein the flexible body assembly comprises a flexible telescopic part arranged in the adjusting foot which is driven telescopically to move in the axial direction by the flexible telescopic part under the action of pressure force for leveling, a friction damping assembly which is arranged between the protective sleeve and the adjusting foot for generating frictional dampingto damp the vibration of the household electrical appliance and an elastic buffering component which comprises an elastic buffering end part abutted against the adjusting foot used for buffering the vibration of the household electrical appliance. According to the foot, a better leveling effect is achieved by matching the friction damping assembly and the elastic buffering component with the hydraulic medium in the foot of the household electrical appliance, and better absorbing and adjusting effects can be achieved particular aiming at the vibration generated in the dehydrating process of a washing machine to reduce dehydrating vibration and dehydrating noise.

Description

technical field [0001] The invention relates to the technical field of home appliance leveling, in particular to a foot for a home appliance and the home appliance. 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 height of the washing machine by screwing the screw of the bolt fo...
