The temporary square wave generated by the temporary square wave generator 7 is input to the controller 1. The control unit 1 drives the fan motor 8 for the blowing fan based on the temporary square wave input through the conversion operation of the transistor 11 (S9), and continues the normal cooling or heating operation of the air conditioner (S9).
이에 따라, 공조기기의 송풍팬용 팬모터 제어장치는, 팬모터의 회전감지회로로부터의 감지신호가 없을 경우에도, 임시구형파발생을 위한 제어명령을 임시구형파발생회로로 제공하여 소정의 팬모터 속도에 대응하는 임시구형파를 발생시켜 적어도 일정시간동안 공조기기의 송풍팬용 팬모터를 정상적으로 동작시켜 공조기기를 정상적으로 운전시킨다.Accordingly, the fan motor control device for the blower fan of the air conditioning apparatus provides a control command for generating a temporary square wave to the temporary square wave generator circuit even when there is no detection signal from the rotation sensing circuit of the fan motor. Generate a corresponding temporary square wave to operate the fan motor of the air conditioning fan of the air conditioner for at least a predetermined time, thereby operating the air conditioner normally.
이상에서 설명한 바와 같이, 본 발명에 따르면, 송풍팬용 팬모터의 회전감지회로에 감지신호가 없을 경우 임시구형파발생을 위한 제어명령을 임시구형파발생회로로 제공하여 소정의 팬모터 속도에 대응하는 임시구형파를 발생시켜 적어도 일정시간동안 공조기기의 송풍팬용 팬모터를 정상적으로 동작시키는 공조기기의 송풍팬용 팬모터 제어장치 및 그 제어방법이 제공된다.As described above, according to the present invention, when there is no detection signal in the rotation sensing circuit of the fan fan motor, a temporary square wave corresponding to a predetermined fan motor speed is provided by providing a control command for generating a temporary square wave to the temporary square wave generation circuit. There is provided a fan motor control apparatus and a control method for a fan fan of the air conditioner to generate a normal operation of the fan motor of the air conditioning fan for at least a predetermined time.
