Abstract
Abstract A cooking oven utilizing in combination, convection, radiant, and pregnation heating. The apparatus includes a cooking compartment positioned between combustion chambers that provide spaced apart confronting heating surfaces which provide radiant heating, and forced circulating heating air passages, each of which have an inlet opening with a closed heated plenum chamber so as to forcibly discharge pregnating heat therethrough into the cooking compartment, with the heated air contained in the cooking chamber providing normal convection heating therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
219 words
An apparatus for cooking a food product by convection, radiant and pregnating heating, including a cabinet like member providing a cooking compartment extending therethrough, and a product supporting and moving means in the cooking compartment, comprising; (a) elongated combustion chambers closed to the cooking compartment and formed by heat transfer plates extending the length of the cooking chamber and forming top and bottom walls thereof for heating the cooking chamber by radiant heat, (b) a heat source for each of said combustion chambers at one end thereof and air moving means in communication with said combustion chambers at the opposite end thereof, (c) plenums spaced from the cooking chamber by each of said combustion chambers and having communication with the combustion chamber through said opposite end thereof so as to receive the heated air moved therethrough by said air moving means, and (d) means providing closed restricted passageways through said combustion chambers between said plenums and said cooking compartment for directly impregnating heated cooking medium into the cooking compartment throughout its length wherein said means providing restricted passageways between said plenums and said cooking compartment comprise a series of tubular members having open communication at one end with said plenums and at the other end with said cooking compartment and extending in a closed condition through said combustion chambers.
Claim 2
Independent Claim
