Abstract: An induction heating cooking apparatus includes a magnetic flux-shielding plate 28 to restrain magnetic flux leakage from a heating coil 24 and define a cooling air trunk 33, through which cooling air from a fan 32 passes. An infrared sensor 26 for detecting infrared rays emitted from a cooking container 22 and a control circuit 27 for controlling an output of a heating coil 24 depending on an output from the infrared sensor 26 are accommodated within the same space with respect to the magnetic flux-shielding plate 28 to thereby enhance assemblage. Also, the infrared sensor 26 is mainly cooled by cooling air passing through a cooling air trunk 33 to thereby enhance the cooling efficiency of the infrared sensor 26 and conduct correct temperature detection.

Abstract: An induction cooking device being capable of heating one target heating object by two or more heating coils and also being capable of displaying the positions of the heating units clearly. The induction cooking device includes a control unit (11) and a plurality of light-emitting parts (21 to 24, etc.). The control unit includes a heating control unit (11a) that controls the output of an inverter circuit and a light-emission control unit (11b) that controls the light emission. When receiving a command for starting heating of one target heating object by one heating coil from an operation unit (7), the control unit turns on only the light-emitting parts provided near the outer circumference of the heating coil for starting heating, and when receiving a command for starting heating of one target heating object by two or more adjacent heating coils having centers at different positions from the operation unit (7), the control unit turns off the light-emitting parts disposed between the heating coils for starting heating out of the light-emitting parts provided near the outer circumference of each one of the heating coils for starting heating, and turns on the light-emitting parts other than the turned off light-emitting parts.

Abstract: An object of the present invention is to provide an induction heating cooker with improved assemblability, and with which a reduction in the temperature sensing precision of an infrared sensor can be suppressed and a reduction in the thickness of the induction heating cooker can be achieved. To this end, the induction heating cooker of the present invention includes a duct 33 that forms a cooling air path for guiding the cooling air produced by the air blower 32 to a control circuit 27 and to an infrared sensor 26. The infrared sensor 26 and the control circuit 27 are disposed at positions lower than the top wall of the duct 33.
