The infrared sensor 26 outputs an detection signal having a substantially constant magnitude with respect to the temperature of the heated object 20 when the temperature of the heated object 20 is lower than a detection lower limit temperature, and outputs a detection signal having magnitude and rate of increase which become larger as the temperature of the heated object 20 becomes higher when the temperature of the heated object 20 is not lower than the detection lower limit temperature. The control unit 29 includes a storage unit 29a operable to store the output value of the infrared sensor 26 immediately after start of heating as an initial detection value, and reduces the output of the induction heating coils or stops the heating when an increased amount with respect to the initial detection value becomes greater than or equal to a predetermined value.

摘要： An induction heating cooker includes a cooking container heating coil, an inverter circuit to supply high-frequency current to the heating coil, an infrared ray sensor to detect radiation from the container, an electric power integrating section to integrate heating electric power from the inverter circuit, and a heating control section to control an inverter circuit output. If the power integrating section has less than a predetermined value when an increase in the output of the infrared ray sensor has a first value after start of heating, the cooker shifts to a first heating control mode and, if equal to or more than the predetermined value, shifts to a second heating control mode. The power, in the first heating control mode, is reduced to a second amount of power lower than the first amount and, in the second heating control mode, is a third amount larger than the second amount.

摘要： There is provided an induction heating cooker capable of preventing a pan having a pan bottom warped in a convex shape or a pan having a pan bottom with a small thickness from being excessively heated. The induction heating cooker includes a heating coil (2) operable to perform induction heating of a cooking container, an inverter circuit (7) operable to supply a high-frequency current to the heating coil, an infrared ray sensor (3) operable to detect an infrared ray radiated from the cooking container, an electric power integrating section (81) operable to integrate an amount of heating electric power outputted from the inverter circuit, and a heating control section (82) operable to control the output of the inverter circuit. If an integrated value from the electric power integrating section is less than a predetermined value when an amount of increase in the output of the infrared ray sensor has reached a first predetermined value after a start of heating with a first amount of heating electric power, the induction heating cooker shifts to a first heating control mode. If the integrated value from the electric power integrating section is equal to or more than the predetermined value, the induction heating cooker shifts to a second heating control mode. In the first heating control mode, the amount of heating electric power is reduced to a second amount of heating electric power lower than the first amount of heating electric power. In the second heating control mode, heating is performed with a third amount of heating electric power which is larger than the second amount of heating electric power.
