ABSTRACT:
The present invention relates, in general, to a temperature controller and heating cable used for electric heating bedding, such as an electric blanket, electric papered floor or electric fomentation device, or warmers and, more particularly, to a controller having a safety device, which can immediately shut off the supply of power when the disconnection, breakage or local overheating of a heating cable occurs while preventing the generation of an induced magnetic field and the leakage of an electric field, in warmers, such as simple bedding or fomentation devices that are operated by allowing a user to simply control a heating temperature to a high or low level without measuring the temperature of a separate heating cable. The controller, having a safety device, for blocking electromagnetic waves includes a switch unit, a heating current U-turn and detection unit, a fuse, and a cutting operation unit.
