<p>PURPOSE:To simplify the constitution of a temperature detecting device by equipping the device for sending a radiowave signal to a control device upon detecting the temperature of contents in a cooking unit, with a power supply device for generating power from magnetic field given by an alternating magnetic field supply device. CONSTITUTION:A wireless probe 18 is set in a pot 11 and a variable resistor 22 is adjusted to set a temperature value corresponding to a cooking temperature. When a DC power supply circuit 1 is supplied with power, a magnetic field feed device operates and alternating magnetic field is generated from an induction heating coil 7. This magnetic field is given to the pot 11 and a heating process starts. In the wireless probe 18, the alternating magnetic field generated from the induction heating coil 7 acts on an induction coil 28 and an electromotive force is generated in the induction coil 28, due to electromagnetic induction. This electromotive force is rectified with a diode 29 and stored in a capacitor 30 for use as a power supply for the succeeding operation of the wireless probe 19.</p> |
