<p>PURPOSE:To supply desired input power to two heating coils through simple constitution in an induction heating cooker loaded with a ceramic plate having the two heating coils. CONSTITUTION:An induction heating cooker is provided with a distributor 13 which performs duty control of the supply of high-frequency currents from first and second inverter circuits 9, 10 in a certain period and at a desired rate and a control portion 14 which controls ON and OFF of first and second switching elements 6, 7 according to signals from the distributor 13 so that power input from an AC power source 1 is equal at the first and second inverter circuits 9, 10. Thereby heating power at first and second heating coils 4, 5 can be freely set and operation with either one of the heating coils 4, 5 is made possible by heating one of them and stopping the other.</p> |
