Embodiment 1

[0029] This embodiment provides a method for controlling a lifting structure, the lifting structure is connected with a driving motor, comprising the following steps: supplying power to the driving motor according to a predetermined voltage, wherein the predetermined voltage is less than the rated voltage of the driving motor; obtaining The lifting speed of the lifting mechanism; when the lifting speed of the lifting structure is less than or equal to the preset speed, increase the value of the predetermined voltage according to the preset speed; when the predetermined voltage increases to the rated voltage, The current value of the drive motor is obtained, and when the current value is greater than a preset current value, the drive motor is powered off.

[0030] In this embodiment, after the predetermined voltage increases to a rated voltage, the current value of the driving motor is obtained, and when the current value is greater than a preset current value, the driving motor...

Embodiment 2

[0037] This embodiment provides a liftable gas cooker, comprising: a lifting structure, a burner head to be lifted is connected above the lift structure, and a cooking range is arranged on the burner head. The driving motor is connected with the lifting structure to drive the lifting structure to perform the lifting action; the lifting controller includes a processor and a memory, and a computer program is stored in the memory, when the computer program is executed by the processor When executed, the processor is made to execute the method provided by the present invention.

[0038]Through the liftable gas range provided in this embodiment, it is possible to lift and control the cooking range whose burner has been set above the burner, so that the position of the cooking range relative to the user can be adjusted, and it is convenient for cooks of different heights to carry out cooking operations. The cooking operation greatly improves the convenience of the gas stove.

Embodiment 3

[0040] This embodiment provides a computer-readable storage medium, which stores a computer program that can be executed by an electronic device. When the program is run on the electronic device, the electronic device executes the computer program provided in Embodiment 1. method steps.

Abstract

The invention provides a lifting structure control method, a liftable gas stove and a computer readable storage medium. In the invention, the current value of a driving motor is acquired when the predetermined voltage increases to the rated voltage, and the driving motor is powered off when the current value is greater than a preset current value. When the predetermined voltage increases to the rated voltage, it is indicated that the speed of the lifting structure itself is low enough. If the current value is greater than the preset current value, it is indicated that the lifting structure hasalmost stopped or completely stopped, so that the power-off operation needs to be performed on the driving motor at the moment no matter where the lifting structure moves.

Description

technical field [0001] The invention relates to the technical field of lifting structure control, in particular to a lifting control method of a lifting mechanism. Background technique [0002] In the prior art, a lifting mechanism is required for carrying out. For the lifting mechanism, the lifting stability of the lifting mechanism is very important. [0003] In the prior art, the PWM duty cycle is usually used to control the motor of the lifting mechanism. By controlling the duty cycle, energy consumption can be reduced. However, for some lifting structures, when the lifting structure rises or falls to the limit position, the lifting structure will stop moving. Or in the process of rising or falling of the lifting mechanism, the situation of stopping motion occasionally occurs. When the above two situations occur, the motor needs to be powered off immediately to avoid burning the motor. [0004] However, in the prior art, the above-mentioned power-off operation is oft...
