Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing, the utility model scheme is applicable to indoor set and powers and off-premises station is powered two kinds of modes.
As shown in Figure 1, the present embodiment proposes a kind of circuit of air conditioner low standby power loss, comprising indoor set circuit and off-premises station circuit, being connected by the holding wire C of power wiring L, N and signal transmission for transmitting alternating current between indoor set circuit and off-premises station circuit.When air conditioner normally works, AC power is by power wiring L, N to off-premises station circuit and indoor set circuit supply, and the telecommunication circuit of off-premises station circuit and indoor set circuit carries out transmission and the reception of signal by holding wire C.When air conditioner is standby, cut off off-premises station completely and power, and when air conditioner room unit receives enabled instruction, power to off-premises station, make it enter normal operating conditions, circuit structure is simple, and fail safe is high.
Below the circuit of the low standby power loss of the present embodiment is specifically described:
In the present embodiment indoor set circuit, alternating current L, N are by exporting direct current to Switching Power Supply after filter circuit filtering, the first rectifier circuit rectifies, and Switching Power Supply is powered to controller and other direct-flow current consumer parts.
Indoor set circuit comprises:
Binding post, connects with power wiring L, n-signal line C and ground wire GND.
Filter circuit, carries out electromagnetic interference suppression to the alternating current of power wiring L, N input.
First rectification circuit, the alternating voltage that filter circuit exports is converted to direct voltage, is indoor set circuit supply.
Second rectification circuit is half-wave rectifying circuit, comprises diode D and resistance R, and the alternating voltage that filter circuit exports is converted to direct voltage, for telecommunication circuit is powered.
Or the present embodiment only arranges the first rectification circuit, the alternating voltage that filter circuit exports being converted to direct voltage, is indoor set circuit supply on the one hand; On the other hand for telecommunication circuit is powered.Above two kinds of modes are all within protection range of the present utility model.
Switching Power Supply, the direct voltage exported by rectification circuit, current conversion are voltage, the electric current of controller and other relevant electricity consumption device requirement, for controller and other relevant electricity consumption devices are powered.
Indoor controller, for receiving remote signal, controlling the on off state of the second on-off switch K2, and remote signal is sent to telecommunication circuit.
Indoor communications circuit, connects with the second rectification circuit, and the second rectification circuit provides power supply for indoor communications circuit, and indoor communications circuit is by holding wire C and the communication of outdoor communication circuit.
Second on-off switch K2 is open type on-off switch, switches the connection of power wiring N and holding wire C and disconnection.
In the present embodiment off-premises station circuit, alternating current L, N are by exporting direct current to Switching Power Supply after filter circuit filtering, rectifier circuit rectifies, and Switching Power Supply is powered to controller and other direct-flow current consumer parts.
Off-premises station circuit comprises:
Binding post, connects with power wiring L, N, holding wire C and ground wire GND.
Filter circuit, carries out electromagnetic interference suppression to the alternating current of power wiring L, N input.
Rectification circuit, is converted to direct voltage, for Switching Power Supply is powered by the alternating voltage that filter circuit transmits;
