INDUCTION HEATING COOKER

摘要

PROBLEM TO BE SOLVED: To solve a problem wherein food during the cooking is spoiled and should be disposed of when heating during the cooking is often stopped since heating is stopped when a surrounding temperature of an induction heating cooker is too high or when an internal temperature rapidly increases due to clogging by dust and oiling at a cooling wind intake port. SOLUTION: This induction heating cooker supplies to a heating coil L after changing into a high frequency alternating current pulse voltage by an inverter circuit connected by a half bridge. A control process calculation circuit SC for controlling the inverter circuit such that a multiplication process signal Sa value is identical with a value set by a power set circuit PC and a first thermostat TH1 are installed in the vicinity of the heating coil L and when the value reaches a predetermined second temperature increase value T2, power of the inverter circuit is lowered by a variable attenuation circuit OA for restraining the temperature increase.
