Hydraulic leveling base and washing machine

Abstract

The invention provides a hydraulic leveling base and a washing machine. The hydraulic leveling base comprises supports which can be combined and connected or used independently, as well as leveling bottom legs disposed under the supports, wherein the upper part of each support is a supporting face used for bearing; and each leveling bottom leg is filled with a hydraulic medium, and the hydraulic medium can flow inside the leveling bottom leg and/or flow between the leveling bottom legs, so automatic leveling can be achieved. According to the invention, the leveling bottom legs are disposed onthe lower parts of the support of the hydraulic leveling base, and the hydraulic medium can flow inside the leveling bottom legs and/or flow between the leveling bottom legs, so the compression amounts of the leveling bottom legs are big under bearing of huge pressure; and the leveling bottom legs bearing small pressure can be lengthened under hydraulic effects, so automatic height leveling can beachieved. The hydraulic leveling base provided by the invention is characterized in that the leveling bottom legs can be adjusted effectively in time according to actual use environments based on hydraulic principles; adjustment effects are better; and applicability is high.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a hydraulic leveling base and a washing machine. 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 foot into th...

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.
