PROBLEM TO BE SOLVED: To provide an induction heating cooling device which allows obtaining the desired input regardless of the size of the load, has a good temp. distribution at a large load, and involves less loss of a switching element. SOLUTION: An interior circumferential side heating coil 25 and an exterior circumferential side heating coil 26 are wound in the same direction, and the inside terminals each other and the outside terminals each other of these heating coils 25 and 26 are connected together so that one parallel connection coil is constituted, whereby it is possible to have a good temp. distribution at a large load, obtain the desired input without causing too high oscillation frequency even with a small load, and lessen the loss of a switching element 27. |
