Washing machine footing with automatic leveling function and washing machine

Abstract

The invention provides a washing machine footing with an automatic leveling function and a washing machine. The washing machine footing includes a sheath, an alignment pin and a flexible body assembly, wherein the alignment pin is arranged in the sheath in an axial motion mode, and the sheath defines the circumferential rotation of the alignment pin; the flexible body assembly is arranged in the alignment pin and used for accommodating a hydraulic medium; the flexible body assembly includes an extension-type end acting on the alignment pin, and under the action of the hydraulic medium, the extension-type end conducts extension and contraction to drive the alignment pin to move in the axial direction so as to achieve automatic leveling. According to the hydraulic principle, the footing is filled with the hydraulic medium, and for different pressure, the footing automatically conducts adaptive adjustment because of the liquidity of the hydraulic medium; besides, through the structural design of the alignment pin and the sheath, the limiting installment of the alignment pin in the sheath is achieved, and it is avoided that the rotation of the alignment pin in the sheath affects automatic leveling of the washing machine, so that the effect of automatic leveling is ensured.

Description

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

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.
