Washing machine with automatic leveling function

Abstract

The invention provides a washing machine with an automatic leveling function. Fixed footings and hydraulic footings are installed on the bottom of a washing machine body respectively, and at least twofixed footings and at least one hydraulic footing form a supporting plane used for supporting the washing machine body; the hydraulic footings comprise fixed parts and movable parts, and hollow cavities are formed between the fixed parts and the movable parts and filled with a hydraulic medium; under the action of pressure, the hydraulic medium can circulate in the hollow cavities in the hydraulic footings and / or a hollow cavity between the hydraulic footings to drive the movable parts to stretch out and draw back; through cooperation of the hydraulic footings and the fixed footings, automatic leveling is conducted. According to the washing machine with the automatic leveling function, the basic principle is used that three points determine a plane, the two fixed footings determine two points, and one hydraulic footing determines the other point, so that it is ensured that even the ground surface is uneven, the fixed footings tightly bear gravity, the hydraulic footings can automatically stretch out and draw back according to borne pressure, and then automatic leveling of the washing machine is achieved.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine with an automatic leveling function. 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 i...

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.
