<p><P>PROBLEM TO BE SOLVED: To suppress AD conversion variance of an AD conversion means without having an adjustment step in the manufacturing process, in an induction heating rice cooker in which a pot is heated by supplying, from an inverter means, a high frequency current flowing in a heating coil. <P>SOLUTION: The pot 1 is heated by supplying a high frequency electric power from an inverter means 3 to a heating coil 2 which is electromagnetically connected to the pot 1 for containing objects to be cooked. A prescribed voltage is outputted from an AD conversion correcting voltage source 10 to the AD conversion means 8 having at least two input terminals, and an AD conversion result by the AD conversion means 8 is corrected using the AD conversion correcting means 11. The AD conversion correcting means 11 corrects the AD-converted result of a prescribed voltage by the AD conversion means 8 and the AD conversion result by the AD conversion means 8 based on an AD conversion theoretical value. A control means 12 is constituted so as to control the inverter means 3 by an input from the AD conversion correcting means 11. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
