PROBLEM TO BE SOLVED: To accurately detect the temperature of a pan mounted on a top plate, in an induction heating cooker. SOLUTION: This induction heating cooker is provided with: a heating coil 21 for heating the pan 20; the top plate 23 disposed over the heating coil 21 for mounting the pan; an infrared sensor 22 disposed on the undersurface of the top plate 23 for sensing infrared rays emitted from the bottom face of the pan; an emissivity obtaining means 28 for obtaining infrared emissivity of the bottom face of the pan 20; a temperature calculation means 24 for calculating the pan bottom face temperature from the output of the infrared sensor 22 and the output of the obtaining means 28; and a control means 25 for controlling the power fed to the heating coil 21 according to the output of the temperature calculation means. Thereby, the temperature of the pan 20 can accurately be measured. COPYRIGHT: (C)2003,JPO |
