<p><P>PROBLEM TO BE SOLVED: To provide a heating cooker equipped with a system for energizing heating coils suitable for cooking stew. <P>SOLUTION: This heating cooker is equipped with a DC power supply circuit, an input current detecting means, a heating coil composed of an inner coil and an outer coil, an output current detecting means, an inverter circuit, and a control means. The control means individually controls the output of high frequency power to the inner coil and the output of high frequency power to the outer coil by controlling the inverter circuit, and controls both the inner coil and the outer coil so that they output base output heating power to make them output certain output heating power. Three heating periods of an inner coil output period T1, 5 in which the inner coil outputs heating power higher than the base output heating power, a base output period T2, 4, 6, 8 in which the inner coil and the outer coil output the base output heating power, and an outer coil output period T3, 7 in which the outer coil outputs heating power higher than the base output heating power are provided, and heating in the inner coil output period and heating in the outer coil output period are alternately performed with heating in the base output period placed between them. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
