Claims (2)
- 파워 온(Power On)이후 초기센서의 출력전압(VO)을 최대치로 인식하여 램(3)에 저장하고 가스센서(8)의 출력전압의 변화율(▲V/▲T)을 비교기(OA)에서 비교하여 기울기가 "0"보다 크면 오염풍량을 최대로 운전하는 단계와, 출력전압의 변화율(▲V/▲T)이 "0"으로 되는 값을 읽어서 새로운 최대치(V0<V1)를 인식하여 새로운 최대치(V1)를 램(3)에 저장하고 초기센서의 출력전압(V0)에 대한 새로운 센서의 최대 출력전압(V1)을 계산하여 N단계로 나누어 오염풍량을 제어하는 단계와, 출력전압의 변화율(▲V/▲T)이 "0"으로 되는 값을 읽어서 새로운 센서(8)의 출력전압(V0>V2)이 최소치일때 새로운 최소치(V2)를 램(3)에 저장하고 최대치(VO)에 대한 최소치(V0)를 계산하여 N단계로 나누어 오염풍량을 제어하는 단계를 포함하여 구성된 것을 특징으로 하는 공기청정기의 자동오염 조절방법.
- 가스센서(8)로 오염상태를 감지하는 오염감지부(1)의 아날로그 출력을 디지탈로 변환하는 아날로그/디지탈 변환부(10)와, 이 아날로그/디지탈 변환부(10)의 디지탈출력을 입력받아 오염도를 판별함과 아울러 그 판별된 데이타를 램(3)에 저항하는 오염도 인식부(2)와, 이 오염도 인식부(2)의 오염도 최대치와 최소치 사이를 N등분 하여 오염도 표시부(5)를 통해서는 오염도를 표시하고 풍량제어부(6)를 통해서는 풍량을 제어하도록 하는 디바이더(4)와, 상기 가스센서(8)의 출력전압 변환기를 측정하는 타이머(7)를 포함하는 공기청정기의 자동오염 조절장치.
