Abstract
본 발명은 쇼케이스의 콤퓨레서에서 발생되는 열을 방열하기 위하여 사용되는 팬모터의 회전수를 변경하는 회로에 관한 것이다. 더욱 구체적으로는 쇼케이스가 설치된 장소의 주변 온도 변화에 따라서 팬 구동 모터의 회전수를 제어하여 냉기가 불균일하게 분산되는 것을 방지하고 에너지를 더욱 효율적으로 사용하기위한 쇼케이스의 팬모터 회전수 변경회로에 관한 것이다.The present invention relates to a circuit for changing the rotational speed of a fan motor used to dissipate heat generated by a compressor of a showcase. More specifically, the fan motor rotation speed change circuit for controlling the rotation speed of the fan drive motor according to the change of the ambient temperature of the place where the showcase is installed to prevent the uneven distribution of cold air and use the energy more efficiently. will be.
본 발명의 실온에 따른 쇼케이스 팬모터 회전수 변경회로는, 소정의 전압을 발생시키기 위한 브릿지 정류기와, 실내 온도를 측정하기 위한 온도 감지 센서와, 상기 온도 감지 센서로부터 입력되는 신호에 따라서 실내 온도를 파악하여 온도에 따른 제어 신호를 출력하는 주제어부와, 상기 주제어부의 신호에 따라서 소정의 제어신호를 출력하는 구동부와, 팬모터의 권선에 각각 연결되는 다수의 릴레이로 구성되는 것을 특징으로 한다.The showcase fan motor rotation speed change circuit according to the room temperature of the present invention includes a bridge rectifier for generating a predetermined voltage, a temperature sensor for measuring an indoor temperature, and a room temperature according to a signal input from the temperature sensor. It is characterized by consisting of a main control unit for grasping and outputting a control signal according to the temperature, a driving unit for outputting a predetermined control signal according to the signal of the main control unit, and a plurality of relays respectively connected to the winding of the fan motor.
