Abstract

본 발명은 가스센서로 실내공기의 오염정도를 검지하여 실내가 오염되면 사용자에게 이를 알리는 동시에, 오염에 대응하여 온풍난방기를 구동함으로써, 난방을 하면서 실내공기를 쾌적한 상태로 유지하기 위한 것으로, 키입력부로 부터의 입력에 따라 난방기의 구동부를 제어하는 마이콤과, 상기 마이콤의 출력신호에 따라 구동되는 릴레이부와, 상기 릴레이부의 개폐에 따라 구동되는 난방부와, 실내의 공기오염상태를 감지하여 상기 마이콤에 그에 따른 신호를 인가하는 가스센서와, 상기 마이콤이 출력에 연결되어 오염여부를 표시하는 표시기로 구성됨을 특징으로 하고, 난방부를 구동시켜 소정시간 초기운전을 한 시점에서 가스센서에 의한 기준전압을 가스의 기준치로 저장하는 단계와, 상기 기준전압과 기준센서에 의해 변화되는 전압을 비교판별하여, 기준치를 넘지 않으면 계속 난방부를 구동하고 넘으면 표시기를 통해 오염표시를 하는 동시에 송풍모터를 제외한 난방부를 정지시키는 단계와, 오염표시 동안에 계속 기준전압과 변화 전압을 비교판별하여 기준치를 넘지 않게 되면 다시 난방부를 정상구동시키는 단계를 포함함을 특징으로 하는 가스센서를 이용한 쾌적난방 회로 및 그 방법이다.The present invention is to maintain the indoor air in a comfortable state while heating by detecting the pollution degree of the indoor air with a gas sensor to notify the user when the room is polluted, and at the same time to drive the warm air heater in response to the pollution, key input The microcomputer for controlling the driving unit of the heater according to the input from the unit, the relay unit driven according to the output signal of the micom, the heating unit driven in accordance with the opening and closing of the relay unit, and the air pollution in the room by detecting the And a gas sensor for applying a signal according to the present invention, and an indicator for displaying whether the microcomputer is connected to the output and indicating contamination. The reference voltage of the gas sensor is driven when the heating unit is driven for a predetermined time. Storing as a reference value of gas, and comparing the reference voltage and the voltage changed by the reference sensor Separately, if the reference value is not exceeded, the heating unit continues to be driven. If the reference value is exceeded, the display unit displays the contamination and stops the heating unit except for the blower motor. The comfort heating circuit using the gas sensor and the method comprising the step of driving the heating unit again normal.
