PURPOSE:To reduce the fire extinguishing time and increase the safety of the titled device by constituting the device so that an ignition device is stopped and only a blower is driven, when the device is turned over and fire is extinguished. CONSTITUTION:When the device is overthrown and fire is extinguished, the seismic automatic fire extinguisher 27 operates and a contact (k) is switched from (l) to (m), a stabilization power source becomes of a low potential, a transistor 38 is turned OFF, and supply of current to a solenoid 6 is lowered and fire is extinguished. However, upon this occasion, the contact 27a is switched to (m). Therefore, different from the ordinary fire extinguishment, even when a temperature switch 26 is closed, supply of current to the ignition heater 25 is not carried out but supply of current only to the blower motor 17a is carried on. Similarly as the time of ordinary fire extinguishment, when the temperature switch 26 is opened, supply of current to the blower motor 17a is stopped. |
