ARRANGING STRUCTURE OF CORE IN INDUCTION HEATING (IH) RICE COOKER

摘要

PROBLEM TO BE SOLVED: To provide an arranging structure of a core in an IH rice cooker by which nonuniformity of boiling is wholly or almost eliminated. SOLUTION: Two coils 2 and 3 are oppositely arranged on a bottom surface of an iron pot 1, and among these, the second coil 3 having a large diameter is arranged so as to wrap a peripheral edge part of the iron pot 1. An annular ring-shaped core 6 is arranged so as to run along only the coil 3. Since the core 6 is arranged, the peripheral edge part of the iron pot 1 is heated strongly and uniformly in the circumferential direction, and nonuniformity of boiling in the circumferential direction can be eliminated.
