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.

Embodiment 1

[0050] Such as Figure 1-8 As shown, the foot of the washing machine with automatic leveling function in this embodiment includes:

[0051] Sheath 500;

[0052] The adjustment foot 300 is arranged in the sheath 500 and can move axially relative thereto;

[0053]And the flexible body assembly 200 is arranged in the adjustment foot 300 for containing the hydraulic medium;

[0054] One end of the flexible body assembly 200 is limitedly installed in the sheath 500, and the other end is a telescopic end acting on the adjustment foot 300;

[0055] The telescopic end of the flexible body assembly 200 expands and contracts under the action of the hydraulic medium to drive the adjustment foot 300 to move axially to achieve automatic leveling.

[0056] In this embodiment, the feet of the washing machine in this embodiment are arranged on the four corners of the bottom plate of the washing machine or at least four are evenly arranged along the circumferential direction of the bottom p...

Embodiment 2

[0116] Such as Figure 1-11 As shown, the foot of the washing machine with automatic leveling function in this embodiment includes:

[0117] Sheath 500;

[0118] The adjustment foot 300 is arranged in the sheath 500 and can move axially relative thereto;

[0119] And the flexible body assembly 200 is arranged in the adjustment foot 300 for containing the hydraulic medium;

[0120] One end of the flexible body assembly 200 is limitedly installed in the sheath 500, and the other end is a telescopic end acting on the adjustment foot 300; the telescopic end stretches under the action of the hydraulic medium to drive the axial movement of the adjustment foot to realize automatic Leveling;

[0121] The flexible body assembly 200 includes a flexible container body, an installation assembly for installing the flexible container body, and a protection mechanism arranged between the installation assembly and the flexible container body for protecting the flexible container body.

[...

Embodiment 3

[0137] This embodiment also provides a washing machine with the above-mentioned washing machine foot with automatic leveling function, which includes a shell, and a plurality of the above-mentioned washing machine feet are installed on the bottom of the shell, and the hydraulic medium filled inside the foot of the washing machine can be Circulation between washing machine feet for leveling.

[0138] The factory setting of the washing machine of this embodiment is preferably that the heights of the feet of the four washing machines are consistent. The washing machine is randomly placed on an uneven bottom surface. The lengths of the press-in sheaths are different, which in turn enables the automatic leveling of the washing machine.

[0139] Need to further illustrate above-mentioned embodiment is:

[0140] 1. The feet in the embodiment of the present invention are connected in pairs, or there may be three or more, the number N≥2, preferably two, the cost is the lowest, and bette...

Abstract

The invention provides a washing machine foot with an automatic leveling function and a washing machine. The washing machine foot includes: a sheath; an adjustment foot arranged in the sheath and capable of moving axially relative to it; and a flexible body assembly arranged in the adjustment foot It is used to accommodate hydraulic medium; one end of the flexible body component is limitedly installed in the sheath, and the other end is a telescopic end acting on the adjustment foot; the telescopic end stretches under the action of the hydraulic medium to drive the adjustment foot to the axial direction The movement realizes automatic leveling; the flexible body component includes a flexible containing body, an installation component for installing the flexible containing body, and a protection mechanism arranged between the mounting component and the flexible containing body for protecting the flexible containing body. In the present invention, the flexible body component is installed in the sheath in a limited position to avoid damage to the flexible body component. In addition, through the setting of the protection mechanism, the flexible containing body is prevented from directly contacting the installation component, which greatly reduces the damage probability of the flexible containing body and prolongs its life. service life.

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...
