PURPOSE: A heater efficiency detecting system is provided to inform replacement time of a heater by checking a current, voltage, efficiency, and short circuit of the heater in real time. CONSTITUTION: Input voltage(AC) is applied in the input side of a heater. A magnet and a heater efficiency detector are successively connected to a wire extend of the heater. The heater efficiency detector outputs a heater current, heater voltage, and an efficiency detection value. An output terminal of the heater efficiency detector comprises a temperature sensor(T). A temperature controller controls on/off of the magnet according to the change of a temperature value of the heater efficiency detector. |
