Abstract

PURPOSE:To permit to transmit or receive in both of indoor and outdoor directions and to operate normally even when the connection of the polarities of power cables is erroneously performed by a method wherein transmission elements, connected to indoor side and outdoor side in anti-parallel connections respectively, are operated mutually during a half cycle of an AC electric source while auxiliary transmission elements are operated instead of an indoor side or outdoor side transmission element when the polarities of the power cables are connected in reverse. CONSTITUTION:When an indoor side controller 8 transmits by conducting a photocoupler 13 at the half cycle A of an electric source 1, an outdoor side controller 12 receives it through another photocoupler 20. On the other hand, the outdoor side controller 12 transmits by conducting the other photocoupler 19 at the half cycle B and the indoor side controller 8 receives it through the other photocoupler 14. Next, when the polarities of power cables 3, 4 are connected in reverse, the photocoupler 25 operates instead of the photocoupler 13 and the photocoupler 26 operates instead of the photocoupler 14. This means that the indoor side controller 8 transmits through the photocoupler 25 when the power cable 4 is positive and the outdoor side controller 12 receives it through the photocoupler 20. Under next half cycle, the power cable 3 becomes positive, therefore, a signal transmission from outdoor side to indoor side may be effected.

(1) An indoor load, an indoor controller for controlling it, and an indoor transmission element are installed on the indoor side, and the indoor transmission element is connected to the indoor side with a voltage applied in one direction. When there is an input signal from the controller, there is an indoor transmitting element that detects it in a non-contact state and sends it out, and when a voltage is applied in the opposite direction to the above direction, the input signal is sent to the indoor controller in a non-contact state. The outdoor side load, the outdoor side controller that controls it, and the outdoor side transmission element are installed on the outdoor side. When there is a signal from the outdoor controller in the applied state, the outdoor transmitter element detects the signal in a non-contact state and sends it out, and when a voltage is applied in the opposite direction to the above direction, the input signal is transmitted to the indoor controller. An auxiliary device configured in the same manner as the indoor transmission device or the outdoor transmission device and arranged in parallel on the indoor side or the outdoor side. installing an auxiliary transmission element consisting of a transmitting element and an auxiliary receiving element, connecting the indoor load and the outdoor load to an AC power source, and connecting one end of the indoor transmission element to a first terminal of the power source; One end of the outdoor transmission element is connected to a second terminal of the power supply, and one end of the auxiliary transmission element is connected to the indoor transmission element on the same side as the auxiliary transmission element among the first and second terminals. A signal transmission device for an air conditioner, which is connected to a terminal different from the terminal to which the outdoor transmission element is connected, and the other ends of the indoor transmission element, the outdoor transmission element, and the auxiliary transmission element are connected to each other.
