LOW-POWER CONSUMPTION STANDBY CIRCUIT DEVICE, AIR CONDITIONER AND CONTROL METHOD FOR AIR CONDITIONER

摘要

Disclosed is a low-power consumption standby circuit device, comprising a primary power supply (13), a secondary power supply (11), a first control switch (12) and a control circuit module, wherein an input end of the primary power supply (13) is connected to an external power supply via the first control switch (12), and an output end thereof is connected to an external load for supplying power to the external load; an input end of the secondary power supply (11) is directly connected to the external power supply, and an output end thereof is connected to the control circuit module; and the control circuit module comprises an MCU module and a signal receiving circuit, wherein the MCU module controls the on-off of the first control switch. Further disclosed are an air conditioner using the above-mentioned low-power consumption standby circuit device, and a control method for the air conditioner. By means of a reasonable power supply distribution, the air conditioner achieves a quasi-0 W standby target, thereby reducing the power consumption in a standby state and also enhancing the anti-interference capability of a main chip.
