<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic cooker inhibiting a switching element from a hard-switching operation, aiming at reduction of leak electromagnetic waves at a low output power area, and realizing efficiency improvement. <P>SOLUTION: The electromagnetic cooker is provided with an inverter circuit 5, heating coils 8, a top plate 10 placed in opposition to and above the heating coils through a magnetic space gap 9, a heated body 13 arranged on the top plate, a lift 11 for adjusting relative positions of the top plate and the heating coils, a lift controlling means 12 activating the lift, adjusting the magnetic space gap, and controlling an output power, and a control means 6 for controlling these above. With this, it becomes possible to control magnetic coupling of the heating coils 8 and the heated body 13 to control loads of the inverter circuit 5, and supply necessary output power with the magnetic coupling of the heating coils 8 and the heated body 13 at the highest state, whereby, reduction of leak electromagnetic waves at a low output power area and efficiency improvement are realized. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
