PURPOSE:To improve the sensitivity of smoke-detection by arranging a smoke- detecting element in on air flow route made by a fan of an air cleaner and the like for controlling the operational state of the air cleaner and the like on the basis of the detected signal of the smoke detecting element. CONSTITUTION:A fan motor 3 is rotated with a ciger lighter and an ash tray being drawn out to form an air flow shown by arrows. At this stage, a smoke detection element 1 arranged in the air flow route ensures the detection of smoke, and a responding signal is rapidly outputted to control the operational state of the air cleaner with sharp response. |
