<p><P>PROBLEM TO BE SOLVED: To correctly boil a cooking object, even if a pan having warpage in the inward direction in the bottom of the pan is used. <P>SOLUTION: This induction heating cooker is provided with a first temperature sensor 4, arranged substantially at the center of a heating coil 3 for sensing the temperature of a heating object 1; and a second temperature sensor 5, arranged halfway of the radial direction of the heating coil 3. A heating control part 12 calculates the differential calculated values of the first temperature sensor 4 and the second temperature sensor 5 at each first predetermined time, after the start of heating, and determines the boiling of a liquid in the heating object, by detecting that either of the variation from the maximum value of the differential values has reached a first predetermined value. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
