PROBLEM TO BE SOLVED: To provide an induction heating cooker capable of coping with both of an operation condition where high heating power such as is required for water boiling is required for only a short time and an operation condition where the high heating power such as is required by a fried dish is required to be maintained for a long-time, and capable of simplifying a cooling constitution. SOLUTION: When the pan bottom temperature detected by an infrared ray sensor 3 shows a predetermined value or higher, and the set heating power shows a first predetermined power or higher, the set time of a timer 10 is extended to a second predetermined time by a fried dish detection means 11.

PROBLEM TO BE SOLVED: To automatically and accurately perform preheating and facilitate transfer to a heating mode after preheating. SOLUTION: A control part 5 executes a first preheating process 20 of performing heating at first heating output 23 after transfer to the preheating mode and completing the heating when detection temperature by a temperature detection part reaches predetermined preheating completion temperature; and a second preheating process 21 of performing heating at second heating output smaller than the first heating output after completion of the first preheating process 20. In the first preheating process 20, change in the heating output by a heating output adjusting part 11 is prohibited, and after transfer to the second preheating process, transfer to the heating mode is performed by operating the heating output adjusting part. Thus, this improves usability of heating cooking accompanied by preheating. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an induction cooking device, which has satisfactory assembling property in setting of a coil support unit and high flexibility of design. SOLUTION: The induction cooking device includes a coil support unit 16 which supports a heating coil 21, a spring 23 which presses the coil support unit 16 in the direction of a top plate 12, and a positioner 26 which regulates horizontal movement of the coil support unit 16 by being fixed to a bottom surface 18 or side surface 19 or both of an outer case 11 to abut on an end 25 of the coil support unit 16. The position of the coil support unit 16 can be easily determined by fitting the end 25 of the coil support unit 16 close to the positioner 26, so that the satisfactory assembling property can be secured. The arrangement of the heating coil 21 is never limited on the coil support unit 16, thereby the flexibility of design is improved. COPYRIGHT: (C)2011,JPO&INPIT
