Abstract
The cooking chamber is defined at least in part by at least two pairs of oppositely disposed first and second wall structures, each of the wall structures including at least one slot opening for the passage of air therethrough. The rotating valve is in heated air distributing communication with the first wall structure and in return air communication with the second wall structure of only one of the two pairs of oppositely disposed first and second wall structures at a selected point in time such that heated air is passed through the slot opening in the first wall structure into the cooking chamber and return air from the cooking chamber is passed through the slot opening in the oppositely disposed second wall structure and to the rotating valve for return to the heat source. The rotating valve is capable of rotation to be in heated air distributing communication with the first wall structure and in return air communication with the second wall structure of the other of the two pairs of oppositely disposed first and second wall structures at a subsequent selected point in time.
