【発明が解決しようとする課題】しかしながら、この様
な電気調理器の構成では電圧が変化してヒータの電力が
変わってしまうと調理の出来上りに著しく影響を与える
欠点があった。However, such a configuration of the electric cooker has a drawback that if the voltage changes and the power of the heater changes, the cooking is significantly affected.

く変化する。FIG. 12 shows a change in the heater power with respect to the power supply voltage. The heater power of 1000 W at 100 V is reduced to 810 W at 90 V, and 12 W at 110 V.
It will rise to 10 W and will vary greatly with voltage.

Therefore, a configuration has been used in which a change in the power supply voltage is detected and the duty ratio or the time is changed according to the change in the power supply voltage.

いた。However, even with such a configuration, if the voltage fluctuates periodically at regular time intervals, the quality of cooking will be affected. Further, in such a configuration, there is a difference in the detection value due to a variation of the component parts or the like, so that adjustment is necessary. Adjustment is performed by setting a semi-fixed resistor on the board.If the characteristics deviate once the board is assembled on the main body after adjustment, the semi-fixed resistor attached to the board must be adjusted. Therefore, there is a disadvantage that the adjustment value cannot be easily changed.
