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. When drying and dehydrating, 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

[0051] like Figure 1-Figure 5 As shown, this embodiment takes a washing machine as an example to provide a foot for household appliances, including:

[0052] Sheath 500, fixed on the bottom of the washing machine;

[0053] The adjustment foot 300 is arranged in the sheath 500 and can move axially relative thereto;

[0054] a flexible body assembly 200 containing a hydraulic medium inside;

[0055] The flexible body assembly 200 is fixedly connected with the sheath 500, and includes a flexible telescopic part arranged in the adjustment foot 300, and the flexible telescopic part expands and contracts under the action of pressure to drive the adjustment foot 300 to move axially for leveling;

[0056] And the frictional damping assembly 900 is arranged between the sheath 500 and the adjustment foot 300 to generate frictional damping to attenuate the vibration of the washing machine.

[0057] When the washing machine is dehydrating, the washing inner cylinder and the clothes in...

Embodiment 2

[0088] like Figure 1-8 As shown, this embodiment takes the washing machine as an example, and provides a foot for household appliances including:

[0089] Sheath 500;

[0090] The adjustment foot 300 is arranged in the sheath 500 and can move axially relative thereto;

[0091] And the flexible body assembly 200 is arranged in the adjustment foot 300 for containing the hydraulic medium;

[0092] 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;

[0093] 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.

[0094] In this embodiment, the feet for household appliances 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 pla...

Embodiment 3

[0159] Such as Figure 9 As shown, the principle of leveling is explained in detail. After the washing machine is installed, due to the unevenness of the ground 600 , the level heights of the feet 800 for different household appliances are different. It can be seen from this that the home appliance foot 800 at a high position first bears the weight of the washing machine, and bears a large gravity, and the home appliance foot 800 at a low position has weak legs or bears little gravity.

[0160] The adjustment foot 300 of the foot 800 for household appliances at a high position will move up under great pressure, and the height of the whole foot will become smaller so that the volume of the hollow chamber of the oil bag 250 filled with hydraulic oil will be compressed and reduced, forcing the hydraulic oil The orifice or valve hole enters the lower foot through the high-pressure oil pipe 700, so that the hydraulic oil in the oil bag 250 of the lower foot becomes more and more, s...

Abstract

The invention provides a foot for a household apparatus and the household apparatus. The foot for the household apparatus comprises a jacket, an adjusting foot, a flexible body assembly and a frictional damping assembly, wherein the jacket is fixed to the bottom of the household apparatus; the adjusting foot is arranged in the jacket and can move axially relative to the jacket; the flexible body assembly contains a liquid pressure medium; the flexible body assembly comprises a flexible telescopic part arranged in the adjusting foot and the flexible telescopic part stretches to drive the adjusting foot to move axially to level under the action of pressure; and the frictional damping assembly is arranged between the jacket and the adjusting foot to generate frictional damping to attenuate vibration of the household apparatus. The frictional damping assembly arranged in the foot for the household apparatus attenuates the vibrating amplitude of the adjusting foot in the jacket effectivelybut does not affect the maximum moving distance H of the adjusting foot in the jacket, so that the maximum range of automatically leveling the household apparatus by the foot for the household apparatus is not affected.

Description

technical field [0001] The invention relates to the technical field of home appliance leveling, in particular to a foot for a home appliance and the home appliance. 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 fo...
