Abstract

PURPOSE: To surely prevent the fire due to overheat or the like by a method wherein the protective means cuts off the electrical transmission at the abnormal heating temperature rise due to the joint use of a plurality of heating apparatus.
CONSTITUTION: When the temperatures of an electric carpet 5 and an electric KOTATSU rise abnormally and the temperature of the heating element 6 of the electric carpet 5 exceeds the predetermined temperature, the heat sensitive layer 6b of the heating element 6 melts to short the heating wire 6c of the heating element 6 with the short-circuit wire 6c of the heating element 6. At the time, there is formed the closed circuit consisting of an AC power source 1, a switch 2, a temperature fuse 3, a first heating reistance 12, a first diode 13, the short-circuit wire 6c, the heat sensitive layer 6b, the heating wire 6a and a relay contact 7a or the closed circuit consisting of the AC power source 1, a second heating resistance 15, a second diode 14, the short-circuit wire 6c, the heat sensitive layer 6b, the heating wire 6a, the temperature fuse 3 and the switch 2 to generate the heat in said first heating resistance 12 or said second heating resistance 15. As a result, the temperature fuse 3 is heated and molten, resulting in performing the protective operation.
