The infrared sensor outputs an initial detection value having a substantially constant magnitude with respect to the temperature of the heated object when the temperature of the heated object is lower than a detection lower limit temperature, and outputs a detection signal having a magnitude and a rate of increase which become larger as the temperature of the heated object becomes higher in the vicinity of a control temperature range in which the control unit controls the output of the induction heating coils to perform temperature control of the heated object. The control unit includes a storage unit to measure and store the initial detection value, and reduces the output of the induction heating coils or stops the heating when an increased amount of the output value of the infrared sensor with respect to the initial detection value stored in the storage unit becomes greater than or equal to a predetermined value.

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.
