A self-leveling washing machine

Abstract

The present invention provides a self-leveling washing machine, which includes a shell and a cylinder assembly arranged in the shell for washing. Leveling feet are installed on the bottom plate of the shell, and hydraulic medium is filled inside the leveling feet. The hydraulic medium can The automatic leveling of the washing machine is achieved through circulation inside the leveling feet and / or between the leveling feet, and the bottom plate of the housing is provided with installation grooves for fixing and installing the leveling feet. In the self-leveling washing machine of the present invention, the hydraulic medium and part of the gas can circulate inside each leveling foot and / or between the leveling feet, thereby achieving a large amount of compression of the leveling feet under high pressure and low pressure. The leveling feet can also be extended under the action of hydraulic pressure, and then the height can be automatically leveled; the installation groove can effectively and quickly position the leveling feet, and the circumference of the installation groove protects the leveling feet, even if it is adjusted The flat foot boots are made of plastic and also provide high reliability in operation.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a self-leveling 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] Take the washing machine as an example, such as figure 1 As shown, the existing washing machine is generally equipped with a support foot 19 at the bottom of the housing 9 or the complete machine. The support foot 19 includes a screw rod, a nut washer and a rubber pad. The nut washer can rotate up and down on the screw rod, and the screw rod can also 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 ...

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.
