example 1

[0059] Example 1: When the non-relay module is a stepper motor, the control module outputs a reduced target control voltage signal to reduce the power supply voltage to the stepper motor (the power supply voltage under normal conditions is 12V / 24V), thereby reducing the stepper motor The energy consumption of the motor. For example, the corresponding relationship between the adjustment value of the target control signal and the voltage difference between the current power supply voltage and the first voltage threshold is stored in advance, and the pre-stored The corresponding relationship of the target control voltage signal is obtained, and the power supply voltage of the stepping motor is adjusted according to the adjusted target control signal.

example 2

[0060] Example 2: When the non-relay module is a display module, the control module outputs a reduced target control voltage signal to reduce the power supply voltage to the display module (normally the power supply voltage is 5V), for example, by adjusting the double-eight digital tube The power supply voltage of the display board is used to reduce the display brightness of the LEDs of the display board, so as to realize the purpose of prompting low voltage and reduce the power consumption of the display module at the same time. For example, the corresponding relationship between the voltage difference between the current power supply voltage and the first voltage threshold and the adjustment value of the target control voltage signal, and the corresponding relationship between the target control voltage signal and the LED display brightness of the display panel, according to the voltage The difference acquires the adjustment value of the target control voltage signal, and adj...

Abstract

The invention provides an air conditioner and a control method and device thereof. The method comprises the following steps that the current power supply voltage of the air conditioner is obtained; and the current power supply voltage is determined to be less than or equal to the first voltage threshold, and the effective power supply voltage of an electric load in the air conditioner is adjusted.According to the control method, the voltage of the electric load under the low voltage can be adjusted, the power consumption of the electric load is reduced, and meanwhile the reliable operation ofthe whole air conditioner under the low voltage is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioner control method, an air conditioner control device and an air conditioner with the control device. Background technique [0002] At present, when the air conditioner operates in heating mode and is powered by ultra-low voltage, the output power of the electronic device will be too large, and even the communication between the indoor unit and the outdoor unit will be affected, resulting in a decrease in the reliability of the air conditioner. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the first object of the present invention is to propose a control method for an air conditioner, which can adjust the voltage of the electric load under low voltage, reduce the power consumption of the electric load, and improve the air ...
