    • It is an object of the present invention to provide a highly-reliable induction heating cooker capable of considerably reducing erroneous detection of boiling over of a cooking container generated at the time of cooking. The induction heating cooker includes a boiling over detecting portion to reduce a heating output of an inverter to a predetermined value when a change amount of electrostatic capacitance detected by an electrostatic capacitance detecting portion with respect to a reference value reaches an output reducing threshold value or more, and the boiling over detecting portion stops a heating action or reduces the heating output to a third set value lower than a second set value when a change rate of the detected electrostatic capacitance reaches a predetermined change rate or more, and maintains the heating output at the second set value when the change rate of the detected electrostatic capacitance is less than the predetermined change rate, during a boiling over determining period started from the time when the change amount of the detected electrostatic capacitance with respect to the reference value reaches the output reducing threshold value or more.
    • 本发明的目的是提供一种高度可靠的感应加热烹调器,其能够显着地减少在烹饪时产生的烹饪容器的沸腾的错误检测。 感应加热烹调器包括沸腾检测部分,当由静电电容检测部分检测到的相对于参考值检测的静电电容的变化量达到输出降低阈值或更大时,将逆变器的加热输出减小到预定值 并且当检测到的静电电容的变化率达到预定变化率或更大时,沸腾检测部分停止加热动作或将加热输出减小到低于第二设定值的第三设定值,并将加热输出保持在 在从检测到的静电电容相对于基准值的变化量达到输出降低的时间开始的沸腾判定期间,当检测到的静电电容的变化率小于预定变化率时的第二设定值 阈值以上。
