For residential use primarily, a compact quick-cooking convection oven for cooking a food product at least partially by hot gas flow, includes a housing defining (i) a cooking chamber having a top, a bottom and a support means therebetween and spaced above the chamber bottom for receiving and supporting a food product for cooking, and (ii) conduit means for providing gaseous communication outside of the cooking chamber upwardly from the chamber bottom to the chamber top. Associated with the cooking chamber are (i) adjacent the chamber top, directing means for directing gas flow from the conduit means downwardly onto a top of the food product on the support means, and (ii) adjacent the chamber bottom, return means for directing the gas flow from the cooking chamber into the conduit means. Flow means cause gas flow from the directing means via the conduit means. Control means independently vary without human intervention at least one of the effective volumetric flow rate of the gas flow into the cooking chamber and the temperature of the gas flow into the cooking chamber. The cooking means are selected from the group consisting of microwave radiant heating, non-microwave radiant heating, convection heating, and combinations thereof.

Compact quick-cooking oven

A microwave oven excitation system comprising a cylindrical microwave launcher for radiating microwave energy into a heating cavity of a microwave oven which is mounted adjacent to the heating cavity in either a substantially vertical position or a substantially horizontal position, a first hollow waveguide secured to the launcher, a first source of microwave energy at a predetermined operating frequency secured to the first waveguide, a second hollow waveguide secured to the launcher substantially perpendicular to the first waveguide, and a second source of microwave energy at a predetermined operating frequency secured to the second waveguide. Alternatively, a single waveguide is secured to the cylindrical launcher and has only a single source of microwave energy secured thereto. In either case, a mode stirrer can be installed within the cylindrical microwave launcher.
