<p><P>PROBLEM TO BE SOLVED: To provide an induction heating device capable of reducing stand-by electric power without damaging misoperation resistance amount due to noises from outside wherein electric power consumption is reduced in stand-by state that a heating sequence is not carried out. <P>SOLUTION: A pan 1 is induction heated by a coil 2, an electrification control element 5 to control an electric current is driven by a drive circuit 7, and the pan 1 is heated by a control means 11 according to the heating sequence. A power supply current is supplied to the drive circuit 7 from a first power supply circuit 12, the power supply current is stepped down by a second power supply circuit 13 and supplied to an operating part 9 and the control means 11 or the like, and an output voltage of the first power supply circuit 12 is switched by a power supply voltage changing means 14. It is constituted so that a set value of the output voltage of the first power supply circuit 12 is switched to a second voltage set value which is set lower than the first voltage set value in the waiting state that the heating sequence is not carried out. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
