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. 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] 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 present invention provides a kind of household appliances and household appliances. The bottom of the household appliances includes: hydraulic plate, liquid flow tract inside; fixed connection with the hydraulic plate;It can be moved relative to its axial movement; the hydraulic plate, protective cover, and adjustment of the feet form a cavity chamber; flexible tolerance body, internal capacity liquid medium, is set in the cavity chamber; under the action of pressure, the flexible flexibility is flexible, the flexible flexibilityThe accommodation of the body telescopic adjustment of the inner axis movement of the feet is tuned; the flexible capacity body has the opening part, which is installed on the hydraulic board through the protective cover sealing through the sheet seal.The present invention uses the fixed installation of the protective cover itself to seal the opening part of the flexible tolerant body on the hydraulic plate. The hydraulic medium in the flexible tolerance can be circulated to the liquid flow channel.Household appliances use the circulation between the bottom feet for automatic leveling.

Description

technical field [0001] The invention relates to the technical field of support and leveling of household appliances, in particular to a household appliance foot and the household 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...
