Compact barbecue oven

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. Moreover, the firebox is exposed to the oven chamber along its cylindrical side wall and end walls, so that maximum transfer of heat to the circulating air occurs. Wood that is placed within the firebox is ignited by a burner that is located in the equipment compartment and projects its flame through a sleeve that extends between the firebox and the vertical partition wall. |

DETAILED DESCRIPTION Referring now to the drawings, a highly compact barbecue oven B includes a cabinet 50 that houses or otherwise supports all of the major components of the oven B.
Among those components are a rotisserie 52 located in the upper portion of the cabinet 50, a firebox 54 located in the lower portion of the cabinet 50, and a burner 56 positioned to direct a flame into the firebox 54.
The cabinet 50 possesses a box-like configuration in that it has four corners formed by left and right side walls 62, 64, a top wall 66, a bottom wall 68, a back wall 70, a front wall 72, all of which are joined rigidly together into the box-like configuration.
In addition, the cabinet 50 has a vertical partition wall 74 which is located between and parallel to the side walls 62, 64, it being closer to the latter than the former.
The partition wall 74 extends upwardly from the bottom wall 68, and near the top wall 66 a small portion of the partition wall 74 flares outwardly toward the side wall 64 to form a flue chamber 76.
The partition wall 74 divides the interior of the cabinet 50 into an oven chamber 78 and equipment compartment 80, the former being between the partition wall 74 and the left side wall 62, while the latter is between the partition wall 74 and the right side wall 64.
The back wall 70 behind the equipment compartment 80 is perfectly flat and extends from the top wall 66 to the bottom wall 68.
However, behind the lower portion of the oven chamber 78 the rear wall 70 is offset forwardly somewhat, it having an oblique section and a short vertical section which provides a recess 82 at the rear of the cabinet 50.
The left side wall 62, the top wall 66, the front wall 72 and the partition wall 74 are all heavily insulated, as it is that portion of the back wall 70 which closes the oven chamber 78.
By reason of the offset at the lower end of the back wall 70, the upper portion of the oven chamber 78 is somewhat deeper that the lower portion.
The upper portion of the oven chamber 78 contains the rotisserie 52 which revolves on an axle 84 that extends between and is supported on the left side wall 62 and the partition wall 74
