Embodiment 1

[0025] The present invention is an electrical appliance with self-leveling feet. In this embodiment, a washing machine is taken as an example, as figure 1 As shown, in this embodiment, four feet are provided at the four corners of the bottom of the washing machine, of which the two feet at the rear are conventional feet 14, and the conventional feet cannot be automatically leveled, but have been fixed at the factory high.

[0026] In this embodiment, the two feet near the front of the appliance are self-leveling feet 13 . In other embodiments, the four feet may also be self-leveling feet.

[0027] Such as Figure 2-5 As shown, the self-leveling foot includes a driving device, a worm, a worm wheel, an adjusting support rod and a bracket. The self-leveling feet are installed on the washing machine through the brackets, and the washing machine is placed on the supporting surface of the feet through the feet.

[0028] The support 2 is groove-shaped, and the two groove walls ar...

Embodiment 2

[0033] The automatic leveling method for electrical appliances with self-leveling feet described in this embodiment is implemented on the electrical appliances with self-leveling feet described in Embodiment 1.

[0034] The electrical appliances are placed on the supporting surface of the feet, which can be a desktop or the ground, depending on the placement of the electrical appliances.

[0035] When the user operates the leveling program, the controller of the appliance sends an instruction to make the pressure sensor installed on the self-leveling foot of the appliance detect the pressure on the supporting surface of the foot and compare it with the set pressure. The set pressure is a range value, and its value It is 1 / 50-1 / 4 of the self-weight of the electrical appliance. If the pressure detected by the pressure sensor is within the set pressure range, the controller of the appliance considers that the ground of the appliance is level and prompts the user; if the pressure ...

Abstract

The invention provides an electrical appliance provided with self-leveling feet and an automatic leveling method. The bottom part of the electrical appliance is provided with the self-leveling feet. Each self-leveling foot comprises a driving device, a bracket, a worm, a worm wheel and an adjustment supporting rod, wherein the driving device is installed on the bracket and drives the worm to rotate, the worm is matched with the worm wheel and drives the worm wheel to rotate, the adjustment supporting rod is threaded in a hole in the bracket, the adjustment supporting rod is provided with teeth which are meshed with teeth of the worm wheel to move upward or downward, the bottom end of the adjustment supporting rod is provided with a pressure sensor, the pressure sensor and the driving device are electrically connected with a controller of the electrical appliance, the controller sends an instruction so that the pressure sensor detects pressure thereon from a ground foot supporting surface and compares the magnitude of the pressure with that of a set pressure, and if the pressure detected by the pressure sensor is within a set pressure range, the controller considers that the electrical appliance is leveled and prompts a user. The electrical appliance can realize automatic leveling, is simple and high in leveling precision, avoids the cumbersome operation of manually screwing the ground feet for leveling, and enhances the user experience.

Description

technical field [0001] The invention relates to an electric appliance with self-leveling feet and an automatic leveling method, belonging to the field of electric appliance leveling devices and methods. 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 t...
