誘導加熱調理器

Induction heating cooker

Abstract

【課題】鍋の中の液体に対流を発生させ、吹き零れを抑制する誘導加熱調理器の提供 【解決手段】主加熱コイルMCと、副加熱コイルSC1〜4と、主加熱コイルMCおよび副加熱コイルSC1〜4と、インバータ回路MIV,SIV1〜SIV4と、これらインバータ回路MIV,SIV1〜SIV4に対して調理メニューに対応した通電パターンを指令する通電制御回路200を有し、通電制御回路200は、初期加熱時の期間T1と、その後の加熱期間T3およびT5において、それぞれ所定の異なる電力を主加熱コイルMCと副加熱コイルSC1〜4に同時に供給し、それぞれの加熱期間の間に、主加熱コイルMCと副加熱コイルSC1〜4に供給する電力を停止する期間T2,T4,T6を挟み、初期加熱T1、T2以降のT3〜T6の期間を繰り返すようインバータ回路MIV,SIV1〜SIV4に指令する。 【選択図】図1
PROBLEM TO BE SOLVED: To provide an induction heating cooker which inhibits boiling over by generating convection of a liquid in a pan.SOLUTION: An induction heating cooker comprises: a main heating coil MC: sub-heating coils SC1-4; inverter circuits MIV, SIV1-SIV4 for the main heating coil MC and the sub-heating coils SC1-4; and an energization control circuit 200 providing the inverter circuits MIV, SIV1-SIV4 with an instruction of an energization pattern corresponding to a cooking menu. The energization control circuit 200 simultaneously supplies predetermined different powers to the main heating coil MC and the sub-heating coils SC1-4 during an initial heating period T1 and following heating periods T3 and T5, respectively, in which periods T2, T4, T6 for stopping supply of power to the main heating coil MC and the sub-heating coils SC1-4 are inserted, and instructs the inverter circuits MIV, SIV1-SIV4 to repeat the periods T3-T6 after the initial heating periods T1, T2.
