    • First material discriminating unit for comparing a magnitude of an input current to inverter circuit and a magnitude of a heating coil current to discriminate a material of cooking container between a non-magnetic body and a magnetic body; second material discriminating unit for comparing a magnitude of the heating coil current and an ON time of switching element when discriminated as the magnetic body by first material discriminating unit to discriminate the material of cooking container as magnetic SUS or iron are arranged, where control unit sets a control temperature lower when the material is discriminated as magnetic SUS by second material discriminating unit than when the material is discriminated as iron so that the temperature of cooking container can be controlled to a predetermined temperature at high accuracy even if cooking container is configured by magnetic SUS, similar to when configured by iron.
    • 第一材料识别单元,用于比较输入电流与逆变器电路的大小和加热线圈电流的大小,以区分非磁性体和磁体之间的烹饪容器的材料; 第二材料识别单元,用于比较加热线圈电流的大小和开关元件的接通时间,当通过第一材料鉴别单元识别为磁性SUS或铁的烹饪容器的材料时,开关元件的导通时间被设置为,其中控制单元设置 当材料被鉴别为铁时,通过第二材料识别单元将材料区分为磁性SUS时的控制温度低于即使烹饪容器由磁性构造而将烹饪容器的温度高精度地控制到预定温度的烹饪容器的温度 SUS,类似于铁配置时。
