Abstract: A cooking apparatus includes a fan 13 provided at the top wall of a heating chamber 2 with its front face directed downwards. A spiral coil 14 in the form of a flat disc is provided around a rotation shaft 12 above the heating chamber 2. When high-frequency current is supplied to the coil 14, the coil 14 generates an alternating magnetic flux. The magnetic flux penetrates a shielding plate 16 and the fan 13, whereby the fan 13 is inductively heated. The fan 13 draws air from the heating chamber 2 and propels the air back to the heating chamber 2, where the air is heated when it contacts the fan 13. As a result, the temperature in the heating chamber rises, so that an object placed on a turntable 5 is cooked. By such a constitution, it is not necessary to keep additional space open for a heating element because the fan 13 functions as a heating element. Accordingly, it is possible to enlarge the diameter of the fan 13 so that the blowing efficiency is enhanced.
