FIRE PROTECTION INTERLOCK METHOD FOR FIRE ALARM, ELECTROMAGNETIC-INDUCED HEATING COOKER, EXHAUST DEVICE SUCH AS RANGE HOOD, AND ALL-TIME VENTILATOR

PROBLEM TO BE SOLVED: To provide a fire protection interlock method for a fire alarm, an electromagnetic-induced heating cooker, an exhaust device such as a range hood, and an all-time ventilator. SOLUTION: A fire detecting unit 3 having a top plate 1a of the electromagnetic-induced heating cooker and its vicinity as a fire detection range 7, and a control unit 4 are attached to be connected each other via a signal line 9, in the exhaust device 2 such as the range hood positioned in an upper side of the electromagnetic-induced heating cooker, detect an ultraviolet ray emitted from a flame 15, or an infrared ray 15a therefrom, sound an acoustic device 5b of a fire alarm unit 5 when an accumulation time exceeds a fixed time (for example, 10 seconds), light a fire lamp 5a on, and transmit an output signal to the electromagnetic-induced heating cooker 1, the exhaust device 2 such as the range hood, and safety devices 10, 10a of the all-time ventilator 8 connected via the control unit 4 and the signal line 9, to interrupt electrification.
