流れ、フォトカプラ１２の２次側１２ｂを導通させる。In this embodiment, a separate type air conditioner for home use is assumed. As shown in FIG. 2, a commercial power supply 2 is supplied to the outdoor unit 1, and power is supplied to the indoor unit 5 through the connection line 3 and the connection line 4. The commercial power supply 2 is supplied to the outdoor unit load 6 and the indoor unit load 7 through the above power supply line. Figure 2 shows
A case is shown in which the indoor unit 5 is on the control signal transmitting side and the outdoor unit 1 is on the control signal receiving side. In the indoor unit 5 on the transmitting side, the commercial power supply 2 supplied through the connection lines 3 and 4 is half-wave rectified by a diode 8 and smoothed by an electrolytic capacitor 9 to obtain a DC power supply section 10. This DC power supply section 1Q includes a circuit formed by the resistor 11 and the secondary side 12b of the photocoupler 12, and the resistor 11. There is a circuit that returns to the DC power supply section 1o of the indoor unit 6 via the connection line 13, the resistor 15, the primary side 14a1 of the photocoupler 14 of the outdoor unit 1, and the connection line 4. Now, considering the time when the transmission control signal 17 is "1", when this transmission control signal 17 is applied to the transmission input terminal 18, the resistance 1
A current flows through the primary side 12& of the photocoupler 12 through the photocoupler 9, making the secondary side 12b of the photocoupler 12 conductive.

１は、「０」となる。Then, current flows from the DC power supply section 10 to the circuit formed by the resistor 11 and the secondary side 12b of the photocoupler 12, but no current flows to the circuit connected to the outdoor unit 1 via the connection line 13. Therefore, photocoupler 1 on the outdoor unit 1 side
Since no current flows through the primary side 14a of 4 and the secondary side 5 vane 14b is not conductive, the voltage at the reception output terminal 2o becomes the power supply voltage ■co, and the reception control signal 21 becomes "1". In other words, the signal "1" has been transmitted from the indoor unit 6 to the outdoor unit 1. Next, the transmission control signal 17 is roJO
Considering the time, when this transmission control signal 17 is applied to the transmission input terminal 18, the primary side 12a of the photocoupler 12
No current flows through. Therefore, since the secondary side 12b of the photocoupler 12 is not conductive, the resistor 11. Via the connecting wire 13, a resistor 15. Current flows through the circuit of the primary side 14a of the photocoupler 14 of the outdoor unit 1 and the connection line 13, the secondary side of the photocoupler 14 becomes conductive, and the voltage at the reception output terminal 2o becomes almost zero. signal 2
1 becomes "0".
即ち、室内機５より、室外機１へ、信号ｒＯＪが送信で

い。Further, as can be easily seen from FIG. 1, even if the connection lines 3, 4 and 13 are connected incorrectly, there is no risk of the equipment breaking down even if it does not operate normally. Therefore, there is no need to separately provide a protection circuit for incorrect connection. 16 Bezo Incidentally, in the above embodiment, the commercial power supply 2 is supplied to the outdoor unit 1 on the receiving side, but it may be supplied to the indoor unit 5 on the transmitting side.
