SAFETY DEVICE FOR PREVENTING GENERATION OF FUME/FIRE

摘要

PURPOSE:To prevent the generation of fume/fire by stopping heating of heating source and suppressing ventilation when the temperature of the heating source reaches an abnormal temperature. CONSTITUTION:A heater 1 to be the heating source is built in a case body 11, a fan 3 to be a ventilation means for the intake of cooled air is fixed to the case body 11 and power is supplied from a power source to the heater 1 and the fan 3 by respective wires 8, 9 through a control device 8. If the temperature of the heater 1 is abnormally raised and exceeds a previously regulated temperature, a power supply circuit is interrupted and the heater 1 is forcedly stopped. Thereby, even if the temperature of combustibles reaches fume/fire generation temperature due to the abnormal temperature rise of the heater 1, air circulation in the device is suppressed and an air lacking state is formed. Thus, the generation of fume/fire can be prevented.
