Abstract
An oven appliance defines a vertical direction, a lateral direction and a transverse direction. The vertical, lateral and transverse directions are mutually perpendicular. The oven appliance includes a cabinet extending between a first side portion and a second side portion along the lateral direction. The cabinet also extends between a top portion and a bottom portion along the vertical direction. The cabinet defines an upper cooking chamber positioned adjacent the top portion of the cabinet and a lower cooking chamber positioned adjacent the lower portion of the cabinet. The oven appliance also includes a single heat source selectively in thermal communication with one or both of the upper cooking chamber and the lower cooking chamber.

An oven appliance defining a vertical direction, a lateral direction and a transverse direction, the vertical, lateral and transverse directions being mutually perpendicular, the oven appliance comprising:
- a cabinet extending between a first side portion and a second side portion along the lateral direction, the cabinet also extending between a top portion and a bottom portion along the vertical direction, the cabinet defining an upper cooking chamber positioned adjacent the top portion of the cabinet and a lower cooking chamber positioned adjacent the lower portion of the cabinet, wherein the upper cooking chamber is thermally isolated from the lower cooking chamber;
- a single heat source selectively in direct thermal communication with one or both of the upper cooking chamber and the lower cooking chamber, wherein the single heat source is positioned outside of the upper cooking chamber and the lower cooking chamber;
- a first duct extending from the single heat source to a broil outlet in the upper cooking chamber;
- a second duct extending to a bake outlet in the lower cooking chamber;
- and
- a fan configured to urge heated air from the single heat source into the second duct.
An oven appliance, comprising:
- a cabinet;
- an upper cooking chamber defined in the cabinet adjacent a top portion of the cabinet;
- a lower cooking chamber defined in the cabinet below the upper cooking chamber and adjacent a lower portion of the cabinet, wherein the upper cooking chamber is thermally isolated from the lower cooking chamber;
- a single heat source selectively in direct thermal communication with one or both of the upper cooking chamber and the lower cooking chamber, wherein the single heat source is positioned outside of the upper cooking chamber and the lower cooking chamber;
- a first duct extending from the single heat source to a broil outlet in the upper cooking chamber;
