<p><P>PROBLEM TO BE SOLVED: To provide an induction heating cooker which can control drive by detecting pan curvature correctly, while incorrect detection of the pan curvature does not occur. <P>SOLUTION: When an operation of the first temperature elevation value▵T1 between a first lapse of time t1 and a second lapse of time t2 from the start of heating is carried out, an instruction for a stop of a heating action is outputted if a comparison between the first temperature elevation value▵T1 and a detection level of the pan curvature set in advance is made and the first temperature elevation value▵T1 is smaller, and furthermore, when the calculation of the second temperature elevation value▵T2 between the first lapse of time t1 and the third lapse of time t3 which is longer than the second lapse of time t2 is carried out, the direction is made to enable a setting temperature to be reduced by a prescribed value if the comparison between the second temperature elevation value▵T2 and the detection level of the pan curvature set in advance is made and the second temperature elevation value▵T2 is smaller. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
