Abstract

PURPOSE:To improve the safety by detecting not only the change of the temperature resistance of an electrode wire but also the potential difference between both ends of the electrode wire. CONSTITUTION:A temperature control circuit consists of an electrode wire 2 which has a one-body constitution and has the resistance value changed by temperature, a heater wire 3, a resin 4 whose impedance is changed by temperature, a power control means 5, a constant current circuit 6, a heating resistance 7, a detecting means 8, a smoothing circuit 9, a temperature setting means 10, a control means 11, a power supply circuit 12, a safety circuit 16, etc. Since the current leaked from the resin 4 is increased at the time of local warming in comparison with the potential difference between both ends of the electrode wire at the time of normal temperature control, the surface temperature of an electric carpet for normalcy is reduced. If the resin is fused, the heater wire 3 and the electrode wire 2 are brought into contact with each other to operate the safety circuit 16 and an AC power source 1 is cut off.
