Abstract

PURPOSE: To reduce noise of an induction heating device, by making the external surface of an induction coil convex and concave alternatively so that the distance between the convex and concave surface is equal to half-wavelength of sound produced by the device for canceling the noise.
CONSTITUTION: The external surface of an inner cylinder 1 is wound up with the same type of induction coils 3, 4 being applied convex and concave alternatively along the length of the cylinder. The difference l between the external surface of the coils 3, 4 is equal to half-wavelength of sound produced by the frequency twice the power voltage. This makes the sound produced by by coils 3, 4 canceled each other, thus reducing the noise of the coils.
