PURPOSE:To permit automatic operation of the device by controlling the blow down directions of warm or cool air so as to be directed to the direction of the position of a remote control device. CONSTITUTION:The detecting and preset data of the temperature sensor S1 at the side of the remote control device and resistors or switches S2-S5 as respective control parameters setting means 6 are converted into signals in the control unit 7 of the control device and are transmitted from a transmitting unit 4 to the receiving unit of the air conditioner main body through infrared rays. The transmitting direction is detected based on the difference of respective receiving signals of photodiodes S6... as a transmitting directing detecting means 8 and the signals thereof are converted by receiving circuits 9... respectively and sent to driving motor circuits 13, 13 for driving louvers 11, 11, changing the blow down direction of warm air into up-and-down and right-and-left directions through comparating and amplifying circuits 10, 10 to control the blow down direction of warm air from blow down ports so as to be directed automatically toward the direction of the position of the control device. |
