<p><P>PROBLEM TO BE SOLVED: To provide an induction heating cooker in which stable temperature adjustment can be carried out in consideration of overshoot due to remaining heat of a buoyancy reducing plate. <P>SOLUTION: The induction heating cooker is provided with heating coils 21, a control means 33, the buoyancy reducing plate 28 on the heating coils 21, a top plate 29 on the buoyancy reducing plate 28, a first temperature detecting means 31 for detecting the temperature of the top plate 29, and a second temperature detecting means 32 for detecting the temperature of the buoyancy reducing plate 28. Upon detecting that the temperature of the top plate 29 has reached a first threshold value, heating power is reduced, and when the temperature of the buoyancy reducing plate 28 is higher than that of the top plate 29, the first threshold value is changed to a second threshold value which is lower than the first threshold value. By this, overheating of heated materials 30 due to the remaining heat of the buoyancy reducing plate 28 is prevented, and when the buoyancy reducing plate 28 is not needed to be considered, heating can be made without changing the threshold value, and the stable temperature adjustment can be carried out. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
