<p><P>PROBLEM TO BE SOLVED: To provide an induction heating type rice cooker reducing the low frequency magnetic field and reducing its release to the outside. <P>SOLUTION: This induction heating type rice cooker is provided with an aluminum shield means 12 having the thickness of 2 mm or more and canceling a leakage magnetic field generated from a heating coil 1 and having a commercial frequency component. Induction current having the low frequency component by the lower frequency magnetic field radiated from the heating coil 1 flows in the shield means 12, consequently the induction magnetic field is generated from the shield means 12 in the direction of canceling the induction magnetic field radiated from the heating coil 1, the mutual magnetic fields are canceled with each other to reduce the generating low frequency magnetic field and reduce its release to the outside. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
