Leveling device of household appliance and washing machine with same

Abstract

The invention provides a leveling device of a household appliance and a washing machine with the same. The leveling device comprises hydraulic bottom legs; each hydraulic bottom leg comprises a fixingpart, a movable adjusting part and a containing cavity; and for each hydraulic bottom leg, the movable adjusting part sleeves the outer side of the fixing part and can move axially relative to the fixing part, the containing cavity for containing a hydraulic medium is formed between the fixing part and the movable adjusting part, and along with the change of the pressure, the hydraulic medium drives the movable adjusting part to axially move along the exterior of a protective sleeve to carry out leveling. According to the leveling device, when the hydraulic bottom legs are fixed on a bottom plate of the household appliance, the movable adjusting part capable of moving up and down sleeves the outer side of the fixing part so that the transverse size of the movable adjusting part can be increased, the contact area between the movable adjusting part and a supporting surface is effectively increased, and the supporting stability of the leveling device on the household appliance is improved.

Description

technical field [0001] The invention relates to the technical field of support and leveling of household appliances, in particular to a leveling device for household appliances and a washing machine with the leveling device. 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...

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] 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.
