<P>PROBLEM TO BE SOLVED: To provide a high frequency induction heating device that reduces heating unevenness by reducing variation in level of an induced current of a high frequency induction heating coil used for the high frequency induction heating device, and making the quantity of variation in a heating state due to load variation small. <P>SOLUTION: The high frequency induction heating device uses the high frequency induction heating coils which are arranged in a wave shape partially or entirely on a forward path from one end side to the other end side, folded back at the other end side, and arranged in a wave shape partially or entirely on the return path while crossing the coil on the forward path. A plurality of unit coils each comprising a coil on the forward path and a coil on the return path are connected in series and arranged side by side in a horizontal or vertical direction. Then a high frequency power supply device 8 is connected to the high frequency induction heating coils 90a, 90b to supply high frequency currents. <P>COPYRIGHT: (C)2013,JPO&INPIT |
