Abstract
버너와, 해당 버너로의 흡기와 배기를 행하는 연소팬과, 해당 버너로의 흡기 통로로부터 배기 통로에 이르는 공기 유통 경로내를 흐르는 풍량을 검출하는 풍량 센서를 구비한 연소 기기에 있어서, 연소팬을 소정의 회전수로 회전시켰을 때의 비정상 상태 또는 수명 판정의 기준이 되는 풍량 판정값을 기억시켜 두고, 연소팬이 0 회전 또는 일정 회전을 하는 것으로 검출되는 풍량 센서의 검출 풍량의 변동이 소정의 허용 범위내에 있을 때, 무풍 상태를 검지하여 그 때, 해당 연소팬을 소정 회전으로 회전시켰을 때의 풍량 센서의 검출 풍량이 풍량 판정값 보다 낮은 경우에, 비정상 상태 또는 수명을 검지하도록 한다. 이에 의해, 외부의 바람의 영향을 받지 않은 상태에서의 풍량과 연소팬의 회전수와의 관계가 양호한 지의 여부를 적절하게 행할 수 있으며, 비정상 상태 또는 수명을 정확하게 판정할 수 있다.A combustion device comprising a burner, a combustion fan that performs intake and exhaust to and from the burner, and an air flow sensor that detects the airflow flowing through the air flow path from the intake passage to the burner to the exhaust passage, The fluctuation of the detected air volume of the air flow sensor detected as the combustion fan rotating at zero or constant rotation is stored in a predetermined allowable range, And when the detected air volume of the air flow sensor at the time when the combustion fan is rotated by the predetermined rotation is lower than the air flow rate determination value, the abnormality state or the life span is detected. As a result, it is possible to appropriately determine whether or not the relationship between the air flow rate and the rotation speed of the combustion fan in a state of being unaffected by the external wind is appropriately performed, and to determine the abnormal state or the life span correctly.
