A microwave delivery system for a cooking appliance includes a toroidal waveguide, a launching zone and a waveguide cover. The launching zone includes opposing top, bottom and side walls that form a pathway for a microwave energy field to travel from a magnetron through the waveguide and into a cooking chamber. In accordance with one aspect of the overall invention, the bottom wall of the launching zone is aligned with a bottom surface of the waveguide to establish a direct conducting surface for the microwave energy field. The waveguide cover shields a hollow interior portion of the waveguide from cooking byproducts generated in the cooking chamber during a cooking process. The waveguide cover is preferably constituted by a metallic conductor having a finish that enhances the microwave energy field distribution in the cooking chamber.

A rapid cook convection oven is constructed to efficiently cook a food item by breaking down a thermal insulation layer maintained about the food, while effectively removing contaminates from within a convection air flow. The rapid cook oven preferably includes both a microwave cooking system and a convection cooking system. The convection cooking system is provided with a dual flow fan adapted to simultaneously draw in an oven air flow from a cooking chamber and a fresh air flow from the surroundings. In order to reduce the presence of contaminates and, by extension, smoke, the two air flows are combined in a mixing chamber and passed over a heating element arranged within a combustion chamber prior to re-entry into the cooking chamber.
