PROBLEM TO BE SOLVED: To make the surface temperature even of a painted object, having a complicated shape, uniform with high accuracy.SOLUTION: A paint drying apparatus includes a position detector 1a for holding three-dimensional proportional control constant information D3 that is set based on the three-dimensional heat capacity information of a painted object 10, and detecting a three-dimensional position, i.e., the heating object position of the painted object 10 by an induction heating coil 3, a temperature detector 1b for detecting the temperature of the painted object 10 corresponding to the three-dimensional position detected by the position detector 1a, and a temperature control unit 1c performing proportional control of the energization power to the induction heating coil 3, by setting the proportional control constant P' so that the temperature of the painted object 10, detected by the temperature detector 1b at the three-dimensional position, based on the three-dimensional proportional control constant information D3 of the painted object 10 corresponding to the three-dimensional position detected by the position detector 1a, becomes the set temperature. |
