ABSTRACT:
A heating apparatus includes a central support axle positioned within a heating chamber of the heating apparatus. The heating apparatus provides both hot-air heating and micro-wave heating. A turntable has a central portion supported by the central support axle so that the turntable is rotated around the central support axle. A driving source is positioned at an upper side of the heating chamber for generating a rotating torque, and a connecting shaft for transmitting the rotating torque generated by the driving source to the turntable is provided in the heating chamber. The turntable has an entirely flat shaped section including a plane on which food products to be heated are mounted. A central portion of the flat shaped section is defined at a concave which is downwardly recessed into the plane and arranged to be fixed to and supported by the central support axis. The plane and the concave of said flat shaped section are provided with a plurality of openings so that hot air and micro-waves can be passed therethrough. The driving axle is engaged, at a lower end portion thereof, with an outer periphery of the flat shaped section to transmit the rotating torque to the flat shaped section.
