Multi-zone oven with variable cavity sizes
First Claim
1. A multi cavity air oven comprising:
- multiple cooking cavities, each cooking cavity including;
(a) an upper plenum defining an upper wall for each given cooking cavity, the upper plenum receiving heated air through an upper air outlet from a wall of the cooking cavity to direct that heated air downwardly into the cooking cavity;
(b) an air return communicating with the cooking cavity to receive return air after passing out of the upper plenum;
(c) an air circulation system including passageways interconnecting the air outlet and air return of the cooking cavity;
(d) a blower positioned to move air from the air return to the air outlet through the passageways;
(e) a heater for heating the air of the cooking cavity;
(f) a lower plenum defining a lower wall of each given cooking cavity, the lower plenum receiving heated air through a lower air outlet from a wall of the cooking cavity to direct that heated air upwardly into the cooking cavity;
a controller independently controlling the heater of each cooking cavity to provide separate temperature control of each cooking cavity;
wherein the air circulation systems of each cooking cavity are isolated from each other to provide separate air circulation within each cavity;
wherein at least one upper plenum is movable to allow changing a size of at least one cooking cavity of the multiple cooking cavities; and
wherein the lower plenum of a first cavity is movable with an upper plenum of a second cavity to allow changing of the size of the at least one cooking cavity.
