(2) automatically sensing program by inductive switch entrance, thermosensitive probe starts to detect ambient temperature, and the temperature signal detected is sent to controller by thermosensitive probe immediately, and smog probe enters armed state；
(3) when starting to cook, pot produces temperature, when controller will detect that temperature automatically turns on blower fan to the most high-grade operating when rising and reach setting value with the initial environment temperature approach cooked before starting；
(4) along with the end of culinary art, pot temperature declines, and the temperature difference of detection is reached automatically to reduce rotation speed of fan to respective notch when setting temperature approach by controller；During downshift; downshift can stop 2～4 minutes at corresponding gear every time; if now temperature rises, controller will control blower fan upshift, when blower fan is preferably minimized grade; pot temperature is close to original ambient temperature; thermosensitive probe enters armed state, and the remaining cigarette of smog probe detection is until can't detect remaining cigarette, and controller enters delay procedure; reach after the delay time set fan parking, enter holding state；
(5) under holding state, if thermosensitive probe detects that ambient temperature rises again, (3), (4) flow process are repeated；If ambient temperature does not rise, and smog probe also can't detect remaining cigarette, and automatic shutdown is cut off the electricity supply；
(6) whole flow process restarts to need to press the most successively by and off switch and inductive switch.
This control flow correspondence culinary art early stage variation of ambient temperature, starts blower fan operating range hood by detection ambient temperature rising change contrast and works；Culinary art regulates rotation speed of fan with variations in temperature and carries out gear shift；Culinary art terminates, jointly acted on by oil smoke and temperature detection and make controller enter time delay, setting delaying of time by one makes blower fan remain in operation with the abundant whole oil smoke getting rid of residual, if now restarting to cook, blower fan accelerated service, the intelligence control system being prevented effectively from existing use is shut down after can't detect oil smoke immediately, again also again button startup whole system to carry out repetitive operation during culinary art, use more scientific, more meet the practice situation of culinary art；Also it is finally to confirm shutdown power-off by smog and temperature detection effect jointly during shutdown.
