Embodiment 1

[0023] The present invention is an electrical appliance with self-leveling feet. There is at least one self-leveling foot among the plurality of feet provided at the bottom of the appliance. In this embodiment, the appliance is described by taking a washing machine as an example. figure 1 As shown, four self-leveling feet 13 are arranged at the bottom of the washing machine.

[0024] The self-leveling foot includes a bracket 2, a worm 3, a worm wheel 4 and an adjustment support rod 5. The driving device drives the worm of the self-leveling foot to rotate, and a clutch with adjustable frictional resistance is arranged between the driving device and the worm. The driving device is set on Inside the electrical appliance housing 11, the worm and the worm wheel are rotatably mounted on the bracket, and the worm and the worm wheel cooperate to make the worm wheel rotate. The adjusting support rod is set in the hole on the bracket, and the adjusting support rod is provided with teeth ...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that: Figure 2-4 As shown, the number of driving devices and clutches corresponds to the number of self-leveling feet, and the self-leveling feet include a worm 3 , a worm wheel 4 , an adjustment support rod 5 and a bracket 2 . The support 2 is groove-shaped, and the two groove walls are arranged up and down and arranged horizontally. The worm screw 3 is vertically arranged in the groove formed by the support 2. The motor 1 is used as a driving device to connect the input shaft of the clutch 9 with adjustable frictional resistance, and the output of the clutch 9 The shaft is connected with the worm screw 3. Both the motor 1 and the clutch 9 are fixed on the support 2 . A worm wheel 4 is arranged in the groove formed by the bracket 2, the worm wheel 4 meshes with the worm 3, the worm shaft 8 is perpendicular to the worm 3, the worm shaft 8 is installed on the bearing seat 7 through the bearing, and the bearing ...

Embodiment 3

[0034] The electrical appliance leveling method with self-leveling feet described in this embodiment is implemented on the electrical appliance with self-leveling feet described in Embodiment 1.

[0035] The bottom of the washing machine has a self-leveling foot. The clutch with adjustable friction resistance, the adjustment range of the friction resistance is 1 / 50-1 / 4 of the weight of the electric appliance. In this embodiment, the frictional resistance is specifically selected to be 1 / 4 of the self-weight of the electrical appliance.

[0036] After receiving the leveling command, the controller of the electrical appliance sends an instruction to make the driving device act and then drive the adjustment support rod of the self-leveling foot mounted on the bottom of the appliance to move downward, and the self-leveling foot moves until the setting between the driving device and the self-leveling foot The friction plate of the clutch with adjustable frictional resistance slips...

Abstract

The invention provides an electric appliance with self-leveled ground feet and a leveling method. At least one of a plurality of ground feet which are arranged at the bottom of the electric appliance is a self-leveled ground foot; the self-leveled ground foot comprises a bracket, a worm rod, a worm wheel and an adjusting support rod; a driving device is adopted to drive the worm rod of the self-leveled ground foot to rotate; a clutch with adjustable friction is arranged between the driving device and the worm rod; the driving device is arranged inside an electric appliance casing; the worm rod and the worm wheel are rotationally mounted on the bracket; the worm rod and the worm wheel are matched to drive the worm wheel to rotate; an adjusting support rod is arranged inside a hole in the bracket in a penetration manner; teeth are arranged on the adjusting support rod and are meshed with teeth of the worm wheel; the worm wheel is matched with the adjusting support rod to drive the upright adjusting support rod to move upwards or downwards; the driving device is electrically connected with a controller of the electric appliance. The clutch is driven by the driving device, furthermore the worm rod of the self-leveled ground foot is driven to act till the friction piece of the clutch slides off, then automatic leveling can be achieved, the operation is simple and convenient, the time and the labor can be saved, the leveling precision is high, and the user experience can be improved.

Description

technical field [0001] The invention relates to an electrical appliance with self-leveling feet and a leveling method, belonging to the field of electrical appliances and the leveling method thereof. Background technique [0002] Existing electrical appliances with feet, such as washing machines, require manual adjustment for the leveling of the feet, which is time-consuming and labor-intensive and has poor precision. Although the existing washing machine has carried out horizontal correction to the four feet of the washing machine when it leaves the factory, the support surfaces such as the bottom surface that each consumer placed on the washing machine is used to support the washing machine are completely different. Once the force on the feet is uneven, or due to the phenomenon of weak legs, the washing machine will produce serious vibration and noise problems during washing, rinsing, especially during the drying process, which will seriously affect the performance of the ...
