Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, 11 is an AC power supply, 12 is a rectifier circuit, 13 is an inverter to which the output voltage of the rectifier circuit 12 is applied and generates high-frequency power, 14 is a control circuit for the inverter 13, and 16
is the power supply terminal of the control circuit 14 and the rectifier circuit 1
This is a DC fan motor that is connected in series between the two output terminals and cools the components that become hot in the induction heating cooker. This DC fan motor 16 and the control circuit 14 constitute a series connection body 15.

To explain the operation in the above configuration, the output voltage of the rectifier circuit 12 is divided between the power supply terminals of the fan motor 16 and the control circuit 14, so the voltage between the power supply terminals of the control circuit 14 is divided between the power supply terminals of the control circuit 14. 12, and the fan motor 16 is also supplied with power.

As for the DC power input to the control circuit 14, it is necessary to input a DC power of about 20V and 120mA as described in the related art.

On the other hand, the fan motor 16 requires an input of about 10 W in order to sufficiently cool the inside of the induction heating cooker. The terminal voltage and current of the fan motor can be adjusted by the wire diameter and number of turns of the coil of the fan motor 16, so the terminal voltage is 80V and the current is 80V.
By setting the current to 120 mA, it is possible to replace the conventional resistor.

Note that if the current value of the DC power input to the control circuit 14 is very small, sufficient current will not be able to flow through the fan motor 16, so in that case, connect a resistor between the power input terminals of the control circuit 14. Therefore, it is necessary to increase the current of the fan motor 16. However, in that case, if the power loss in the resistor becomes extremely large, this embodiment is not suitable.
Even in that case, the voltage applied to the voltage dropr can be lowered by the amount of the fan motor compared to the conventional technology, making it possible to downsize the voltage dropr and supply current to the fan motor. There is an effect that it can be done.
