PURPOSE: A heating controller having no magnetic field in a double safety structure is provided to prevent fire or an overheated heating wire due to an abnormal electronic component by forming a power device for controlling heating into a double safety structure. CONSTITUTION: A heating controller having no magnetic field in a double safety structure is composed of a DC power supply unit, a main control unit, a first signal sensing unit, a second signal sensing unit, a trigger generation unit, power control unit, and an action display unit. The action display unit displays existence and nonexistence of a drawing voltage. The action display unit displays supply of a current provided to a heating wire. The DC power supply unit receives the power necessary for a trigger action of a triac(Triode Ac Switch) and MICOM(Microprocessor Computer). One end of a condenser is connected to an input terminal of a diode and an output terminal of a Zener diode. The input terminal of the Zener diode is connected to the drawing voltage. |
