Abstract: A multifunctional cooking oven for the preparation of food products including a cooking chamber, racks within the cooking chamber to support products to be prepared in the oven and a primary convection heat source. There is a drainable collection pan positioned below the racks to collect by-products rendered from the food products during preparation for later use. A steam source is positioned below the collection pan as well as a flavored smoke generator at the bottom of the preparation chamber. Airflow paths within the preparation chamber allow for the circulation of heat, steam and flavored smoke around the racks. The oven includes a programmable controller to control the primary heat source, the steam source and the flavored smoke generator that is programmed to operate any one of the heat source, the steam source and the flavor generator in any predetermined sequence, and for any predetermined duration of time to provide optimum preparation and flavoring of the products.

Abstract: A highly compact oven for preparing barbecued foods on a commercial basis includes a cabinet having a vertical partition wall that divides its interior into an oven chamber and an equipment compartment, and doors which provide access to the oven chamber. In addition, the oven has a rotisserie for supporting foods in the upper portion of the oven chamber opposite one of the doors, and this rotisserie is turned by a motor in the equipment compartment. A cylindrical firebox in which wood is burned is located in the lower portion of the oven chamber opposite another of the doors to provide the heat required for cooking the food and the smoke for imparting the barbecue flavor to that food. Food on the rotisserie is shielded from the firebox by a baffle wall which extends across the oven chamber, yet has its margins spaced from the front and back walls, so that heated air and smoke circulate freely between the region of the firebox and the region of the rotisserie.

Abstract: An oven that is particularly suited for preparing barbecued foods with minimal consumption of wood includes a housing that encloses an oven chamber and an apertured firebox that extends into the oven chamber from one of the housing walls. The firebox is closed by a door that is located at the exterior of the housing, and through this door firewood may be placed into the firebox. That wall of the housing which is located opposite the firebox door supports a conversion-type gas burner having a blast tube that is directed into the firebox to provide a gas flame that serves not only to ignite the wood in the firebox, but also to provide supplementary heat, if necessary. The firebox, although being in the oven chamber is shielded from the portion of the chamber in which the food is cooked by a partition wall, and that wall together with one of the housing end walls supports a rotisserie that carries the food as it is cooked.
