Bottom foot for household electrical appliance and household electrical appliance

Abstract

The invention provides a bottom foot for a household electrical appliance and the household electrical appliance. The bottom foot for the household electrical appliance comprises a hydraulic plate, asheath, an adjusting foot, hydraulic medium and a communicating device, wherein the sheath is fixedly connected with the hydraulic plate; the adjusting foot is arranged in the sheath and can move axially relative to the adjusting foot; a containing cavity is formed among the hydraulic plate, the sheath and the adjusting foot; the hydraulic medium is arranged in the containing cavity, and the hydraulic medium is compressed along with the change of the pressure and the adjusting foot is expanded to drive the adjusting foot to axially move in the sheath to be leveled; the communicating device communicates with bottom feet of at least two household electric appliances to achieve the circulation of the hydraulic medium in the bottom feet of the household electric appliances; and a throttling structure used for relieving the flow velocity of the hydraulic medium is arranged in the communicating device. According to the bottom foot for the household electrical appliance, the throttling structure is arranged in the communicating device, so that the rapid flowing of the hydraulic medium is avoided, and the adjusting process is more stable; and in addition, the throttling structure can havea good buffering function under the condition that the pressure change of the bottom foot of the household electrical appliance is large.

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...

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 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.
