Patent ID: 7435931

Claim:
An oven for cooking a food product, comprising: a cooking chamber comprising a top and a support for receiving the food product for cooking; a conduit for providing a gas into the cooking chamber; a thermal energy source for heating the gas disposed in the conduit; a first nozzle for causing a first impingement of the gas from the conduit into the cooking chamber; a second nozzle for causing a second impingement of the gas from the conduit into the cooking chamber; one or more magnetrons; a first microwave resonator for directing a first microwave energy generated by the one or more magnetrons into the cooking chamber; and a second microwave resonator for directing a second microwave energy generated by the one or more magnetrons into the cooking chamber, wherein the first nozzle is configured and positioned to direct the first impingement of the gas generally toward a first side of the support, the second nozzle is configured and positioned to direct the second impingement of the gas generally toward a second side of the support, the first and the second sides being generally opposite sides of the support, and the first and the second nozzles are further configured and positioned to respectively direct the first and the second impingements of the gas to meet each other above the food product on the support in the cooking chamber, and wherein the first microwave resonator is configured and positioned to direct the first microwave energy to propagate generally toward the first side of the support, the second microwave resonator is configured and positioned to direct the second microwave energy to propagate generally toward the second side of the support, and the first and the second microwave resonators are further configured and positioned to respectively direct the first and the second microwave energies to cross at a distance from the support in the cooking chamber.
