Abstract
An induction heating cooker includes a scorching detection portion adapted to output scorching detection information, when the temperature of a cooking container comes to be equal to or higher than a second set temperature, based on infrared-ray detection information (A) from an infrared sensor for detecting infrared rays from the cooking container, in a heating mode which enables setting the output. A control portion is adapted to perform heating-output suppression operations for preventing the progress of scorching, when the scorching detection portion outputs scorching detection information. Further, the control portion is adapted to prohibit such heating-output suppression operations and to continue heating operations, even if the scorching detection portion outputs scorching detection information, until the measured cooking time period after start of heating operations reaches a first set elapsed time period (T1).
