<p><P>PROBLEM TO BE SOLVED: To provide a rice cooker which easily reduces a low-frequency leaking magnetic field contained in a heating coil. <P>SOLUTION: A magnetic field generated from a low-frequency magnetic field cancelling means 12 which is located in a high-frequency oscillating section 11, has the same frequency component as a low-frequency component of a current flowing on a side surface heating coil 1b, and is arranged in such a manner that a current may flow in the direction opposite to that of the side surface heating coil 1b mutually negates leaking magnetic fields from the side surface heating coil 1b where many leaking magnetic fields of low frequencies are generated, and the leaking magnetic fields of the low frequencies are greatly reduced. At the same time, by arranging the low-frequency magnetic field cancelling means 12 on the side surface of an internal frame 16, a distance can be placed from the bottom surface and the side surface heating coil, and the effects to the high-frequency magnetic field which is used for induction-heating can be reduced, and the effects to the rice cooking performance can be suppressed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
