RICE COOKER

摘要

PROBLEM TO BE SOLVED: To provide a rice cooker which easily reduces a low-frequency leakage magnetic field included in a heating coil.

SOLUTION: The coiled wiring 12 which is disposed in a coil shape in the vicinity of the heating coil 1 in an inverter 11 to flow an electric current in a reverse direction of the heating coil 1 with the same frequency component of a low-frequency component of the electric current flowing in the heating coil 1 sharply reduces the low-frequency leakage magnetic field by a mutual counteraction of the low-frequency magnetic field generate by the coiled wiring 12 and the low-frequency magnetic field from the heating coil 1, and the magnetic field generated by the coiled wiring 12 can be prevented to penetrate in a first magnetic body 13 by disposing a second magnetic body 17 in the vicinity of the coiled wiring 12 so that a decline of a capacity of the rice cooker due to a decline of a magnetic capacity of the first magnetic body 13 can be prevented.
