ELECTROMAGNETIC INDUCTION THERMAL COOKER AND RESIN COATED FERRITE CORE

摘要

PROBLEM TO BE SOLVED: To reduce the cost of parts by arranging at least two ferrite core parts and a resin coated part coated with a resin so that the ferrite core part forms a bent part to be connected thereto. SOLUTION: The bottom of a housing part of the body 9 comprises a coil base 2 which is arranged crossing the body 9 to be formed with the center thereof corresponding to the outline of an inner pot. A coil 5 is provided below the coil base and a resin coated ferrite core 1 is provided at a lower part thereof. The ferrite core 1 is constituted of linear parts 15a and 15b and a bent part 13 made between the linear parts, ferrite core parts 51a and 51b comprising a pair of square bar-shaped ferrite core pieces are arranged to make an obtuse angle therebetween that allows the ferrite core parts to correspond to the bottom of the inner pot 7 and a resin coated part 21 is formed by a resin coating. The bent part 13 is formed by the resin coated part 21 between both one ends as opposed to each other of the ferrite core parts 51a and 51b.
