When the rectifying module 50 outputs a dc voltage at its output terminal, the dc voltage is input to the second control terminal of the second switching module 20, so that the second switching terminal is closed, and thus the power is introduced to the outdoor main board, thereby supplying power to the outdoor main board. In one embodiment, the rectifying module 50 includes a bridge rectifier circuit composed of four diodes, which has the advantages of high rectifying efficiency and low circuit cost.

the cathode of the voltage stabilizing diode D1 is connected with the first output end P, and the anode of the voltage stabilizing diode D1 is connected with the second output end Q.

After the outdoor unit main board is powered on to work, the power supply signal detected by the power supply detection module is received in real time, when the power supply module 40 is judged to work continuously according to the power supply signal, namely the indoor unit main board always controls the first switch module 10 to be kept in a closed state, the outdoor unit main board controls the third switch module 30 to be closed, at the moment, the power supply is introduced into the outdoor unit main board and the indoor unit load, and the outdoor unit load enters a working state after being powered on.
When the indoor unit main board receives an air conditioner standby signal B for controlling the standby of the air conditioner, the indoor unit main board controls the first switch module 10 to be turned off, at this time, the second switch module 20 is in an off state because no voltage/current is input, and when the second switch module 20 is turned off, the outdoor unit main board is still in a working state because the third switch module 30 is still in a closed state (the power supply supplies power to the outdoor unit main board and the outdoor unit load through the third switch module 30). Meanwhile, since the first switch module 10 is turned off, the power supply detection module cannot detect a power supply signal or detects that the power supply signal is 0, and the outdoor unit main board determines that the power supply module 40 stops working according to the power supply signal, then the outdoor unit main board controls the third switch module 30 to be turned off, so that the power supply of the outdoor unit load is turned off, and the outdoor unit main board also cuts off the power supply of the outdoor unit main board after the third power supply module is turned off, that is, the outdoor unit load and the outdoor unit main board are both in a power-off state.
In summary, in the embodiment of the method, the operation mode of the standby control circuit is controlled to be switched to the standby mode through the mutual cooperation of the indoor unit main board and the outdoor unit main board, in the working mode, the indoor unit main board controls the first switch module 10 to control the second switch module 20 to be closed, so that the outdoor unit main board is powered on, and the powered-on outdoor unit main board controls the third switch module 30 to be closed, so that the power supply supplies power to the outdoor unit main board and the outdoor unit load; in a standby mode, the indoor unit main board controls the first switch module 10 to control the second switch module 20 to be switched off, and the outdoor unit main board controls the third switch module 30 to be switched off according to a power supply signal, so that the outdoor unit main board and the outdoor unit load are both in a power-off state, the power supply of the outdoor unit is cut off, and the purpose of low-power standby of the air conditioner is achieved.
