御電源のみで行っている。2. Description of the Related Art The applicant of the present invention has disclosed a control circuit for an indoor unit and an outdoor unit of an air conditioner, a control power supply for supplying power to the control circuit, and means for reducing standby power.
No. 700, proposed by the present applicant. Here, the electric power supplied to the control circuits of the indoor unit and the outdoor unit is controlled only by the control power supply of the outdoor unit.

There are various fan motors for heat exchange and wind direction plate driving.
DC power is supplied to the control object excluding the compressor by the control power supply of the outdoor unit. On the other hand, a DC power is supplied to the compressor by separately rectifying and smoothing a commercial power supply for driving the compressor.

御回路に供給されることによる。A switch is connected to a path for supplying DC power by rectifying and smoothing a commercial power supply for driving the compressor. When the compressor is turned off, the switch is turned off to stop power supply to the compressor. are doing. Also, various valves such as an electric expansion valve constituting a refrigeration cycle excluding a compressor, and various fans such as a fan motor for heat exchange and wind direction plate driving are controlled even when power supply to the compressor is stopped. The DC power is always supplied from the control power supply of the outdoor unit to the control circuits of the indoor unit and the outdoor unit. This is because commercial power is directly input through the rectifier circuit at the input stage of the control power supply, so even when the power supply to the compressor is stopped, DC power is always supplied from the control power supply of the outdoor unit. This is due to being supplied to the control circuits of the indoor unit and the outdoor unit.

を低減している。[0005] The control circuit of the indoor unit and the outdoor unit includes a communication circuit. Normally, during operation, it is necessary to control the indoor unit and the outdoor unit in accordance with the operation mode and the set temperature with a remote controller. For this purpose, communication is performed with the indoor unit and the outdoor unit, but there is no necessity at the time of standby. Therefore, the standby power of the air conditioner is reduced by stopping the communication to reduce the power consumption of the communication circuit.

とに対し配慮されていない。In the above-mentioned circuit and the means for reducing standby power, no consideration is given to unnecessary power consumption during a light load when the compressor is stopped, that is, during standby.

Although various fan motors and the like for heat exchange and wind direction plate driving are driven, they are not required at all.

る。Therefore, when the compressor is stopped, there is no need to supply power to the control circuits of the outdoor unit and the indoor unit for controlling these various valves, various fan motors for heat exchange and wind direction plate driving, and the like. The same applies to the communication circuits in the control circuits of the indoor unit and the outdoor unit. Although power is supplied to the control circuits of the indoor unit and the outdoor unit using the control power supply of the outdoor unit, since the commercial power supply is directly input through the rectifier circuit at the input stage of the control power supply, the drive of the compressor is performed. Even when the power is off, DC power is always supplied to the control circuits of the indoor unit and the outdoor unit by the control power supply of the outdoor unit, and unnecessary power is consumed by the control power supply of the outdoor unit and its load. I have.

な理由である。In general, since the control power supply of the outdoor unit is usually designed to be most efficient at the time of load, when various valves, various fan motors for heat exchange and wind direction plate driving are stopped, etc. When the load is light, the efficiency decreases. These are the main reasons for consuming unnecessary power during standby.

Safety issues such as the mounting of parts for the equipment have newly occurred, and the conventional circuit, that is, the commercial power received indoors is transmitted outside, the outdoor unit converts to low-voltage DC, and the standby power is supplied to the indoor unit to reduce standby power. There was a need for a reduced air conditioner.

れる。A description will be given of a case where a transition is made from the normal operation to the standby operation in the above configuration. Upon receiving a stop command from the remote controller (not shown), the compressor 19 is stopped from supplying power from the commercial power supply 1 and turns off the power relay 14. At this time, the power relay 14 receives a signal from the outdoor microcomputer 33 so as to maintain the off state.

To turn it off, power may be supplied or stopped to the coil portion of the relay used for the outdoor control power switch 21,
A transistor 21C is provided for this. Next, a control signal 35 of HI or LOW is output from the outdoor microcomputer 33 to turn on / off the transistor 21C. However, since the power supply potentials of the outdoor microcomputer 33 and the outdoor control power switch 21 are different, the photocoupler 21A is turned off. They are used to insulate and control each other. Therefore, the transistor 2 on the primary side of the photocoupler 21A
By giving a HI or LOW control signal 35 to 1B, the outdoor control power switch 21 can be turned on / off. By the above operation, the power consumption of the load connected to the outdoor control power supply 23 becomes zero. By turning off the outdoor control power supply 23, power is supplied to the indoor unit 11 from the auxiliary power supply 29. At this time, a voltage (12 V in the embodiment) lower than the voltage (35 V in the embodiment) output from the outdoor control power supply 23 to the indoor unit 11 in the normal state is supplied from the auxiliary power supply 29 to the indoor unit 11, and Power consumption is reduced.

通常運転時より低減できる。FIG. 3 is a circuit diagram for reducing the power supplied to the communication relay 26. 26A and 26B are transistors, and 26C is a resistor. In order to reduce the power supplied to the communication relay 26, the power supplied to the coil of the communication relay 26 may be reduced. Therefore, the current flowing through the coil of the communication relay 26 is reduced by the resistor 26C. Here, the electric power flowing through the coil portion of the communication relay 26 can be reduced after the contact of the communication relay 26 is held. Therefore, when the communication relay 26 is turned on, the on / off signal 36 of the communication relay 26 is supplied to the transistor 26A by HI.
The transistor 26A is turned on during standby when the communication relay 26 is in a holding state, and the transistor 26A is turned on.
In order to turn B off, the power supply reduction signal 37 when the communication relay 26 is on is given to HI, and the on / off signal 36 for the communication relay 26 is given LOW. Thus, the power supplied to the communication relay 26 is reduced. The same effect can be obtained by using a MOS relay or a latch relay as the communication relay 26. Further, the power consumed by the outdoor microcomputer 33 can be reduced from that in the normal operation by setting the power consumption mode in which the operation of the CPU is stopped.

R1 and R2 are resistors, and 5A is a transistor. The output voltage of the indoor control power supply 5 is set by 1 + R1 / R2. Therefore, the output voltage of the indoor control power supply 5 can be switched by changing the resistance value of the resistor R2. Here, the switching voltage of the output voltage of the indoor control power supply 5 is given to the transistor 5A to change the resistance value of the resistor R2, thereby switching the output voltage. That is, at normal times,
The switching signal of the output voltage of the indoor control power supply 5 is set to LOW, the resistance value of the resistor R2 is reduced to increase the output voltage, and during standby, the switching signal of the output voltage of the indoor control power supply 5 is set to HI and the resistance value of the resistance R2 is set to HI. The power consumption of the indoor control circuit is reduced by increasing the output voltage and decreasing the output voltage.
