PROBLEM TO BE SOLVED: To provide a heating cooker that accurately detects the existence of a load in a heating chamber and a situation of the load and is capable of performing heating control depending on a state of the load.SOLUTION: A heating cooker of the present invention comprises: a heating chamber for housing a load; a micro wave oscillator for oscillating a micro wave to be supplied to the heating chamber; a transmission path provided between the heating chamber and the micro wave oscillator, the transmission path transmitting the micro wave; temperature detection means provided outside the heating chamber, for detecting a surface temperature of the load; reflection wave detection means for detecting a micro wave reflected in the transmission path; and control means for controlling the micro wave oscillator on the basis of output of the temperature detection means and the reflection wave detection means. The control means varies control of the micro wave oscillator depending on a reflection amount or reflection ratio of a micro wave detected by the reflection wave detection means, even when the load's surface temperature detected by the temperature detection means has not varied.SELECTED DRAWING: Figure 1 【課題】 加熱室内の負荷の有無、負荷の状況を正確に検知し、負荷の状態に応じて加熱制御できる加熱調理器を提供する。【解決手段】 上記課題を解決するため、本発明の加熱調理器は、負荷を収納する加熱室と、該加熱室に供給するマイクロ波を発振するマイクロ波発振器と、前記加熱室と該マイクロ波発振器の間に設けられ、前記マイクロ波を伝送する伝送路と、前記加熱室の外側に設けられ、前記負荷の表面温度を検知する温度検知手段と、前記伝送路に反射するマイクロ波を検知する反射波検知手段と、前記温度検知手段と前記反射波検知手段の出力に基づいて前記マイクロ波発振器を制御する制御手段と、を具備し、前記制御手段は、前記温度検知手段が検知した前記負荷の表面温度が同じであっても、前記反射波検知手段が検知したマイクロ波の反射量または反射比に応じて前記マイクロ波発振器の制御を変えるものとした。【選択図】図１
