<p><P>PROBLEM TO BE SOLVED: To provide an induction heating apparatus that has a configuration and a structure where optimum characteristics are introduced to reduce copper loss and magnetic flux loss of a heating coil, in which the high-frequency resistance of the heating coil is set low, to reduce copper loss, and the magnetic flux loss of the heating coil is reduced for improved heating efficiency. <P>SOLUTION: The heating efficiency is attained by employing a configuration where the best value in the number of wires for avoiding proximity effect is selected, and such structure of best distance range of the interval between the core of the heating coil and coil-avoiding self magnetic field effect. The induction heating apparatus causes reduced copper loss of the heating coil and reduced magnetic flux loss, for improved heating efficiency. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
