<p><P>PROBLEM TO BE SOLVED: To improve design flexibility inside a cooker body by efficiently cooling heating members such as an induction heating coil and a switching element, and to increase and decrease the output of the induction heating coil as required. <P>SOLUTION: A plurality of inverters corresponding to a plurality of induction heating coils 11a, 11b are arranged on one base board, and a radiator plate 3 mounting positive and negative switching elements 2a, 2b, 2c, 2d constituting these inverters is made common. Thereby, a control part 1 can be compactified, and also, when one of the induction heating coil out of the plurality of induction heating coils 11a, 11b is used at a rated output value or less, the other induction heating coil can be used at an output exceeding the rated value within the range not exceeding the heat radiation capacity of the radiator plate 3. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
