Abstract
PURPOSE: To attain safety by providing a temperature fuse that stops electric feed to a heating element through the breaking of the wire of the heating element or a heat sensitive element and operates at a temperature beyond the allowable range of the heating element or a higher temperature at which a melting layer melts.
CONSTITUTION: While the temperature of a heat sensitive element is low and the impedance of heat sensitive layer 10 of it is high with electric power switch 2 turned on, heating element 47 is turned on and the temperature of the carpet rises. Then, when the temperature reaches the saturation temperature (dangerous state) of the carpet exceeding the set temperature of variable resistor 18, the 3rd heating resistance 41 is turned on through the operation of the 2nd SCR42, and consequently temperature fuse 3 is brown for its safey. In this state, in case that temperature fuse 3 is not brown when the 2nd SCR42 is not in operation due to some reason, the temperature of the heating element further rises and melting layer 46 melts, setting a short-circuit state. In accordance with the short-circuit point, the 1st or 2nd heating resistance 4 or 44 is heated up to blow temperature fuse 3.
