<P>PROBLEM TO BE SOLVED: To reduce power consumption by making a heat value of a tube body partially different or zero, in an induction heating device which generates an induction current on the tube body and heats the tube body by conducting an alternating current through an insulation electric wire inserted in the tube body. <P>SOLUTION: A tube body 22, in which an insulation electric wire 3 energized with an alternating current is inserted, is constituted by plural members 22a, 22b, 22c with different magnetic permeability. When the alternating current is conducted through the insulation electric wire 3, an induction current is generated on the tube body 22 according to its magnetic permeability by electromagnetic induction due to an alternate magnetic flux of the alternating current. The tube body 22 is constituted by plural members with different magnetic permeability, and therefore, induction currents with different magnitudes are generated on each member of the tube body 22 according to a level of the magnetic permeability. As a result, a heat value is different for each member constituting the tube body 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
