Abstract
A convection oven is described that provides a more desirable cooking condition. The convection oven includes a cooking cavity having sidewalls, a ceiling and a floor and a combustion chamber below the cooking cavity for heating combustion gases to be supplied to the cooking cavity. A blower fan within the cooking cavity circulates air inside the cavity. As part of the airflow path from combustion chamber to the blower fan is an intermediate flow chamber disposed between the cooking cavity and the combustion chamber. By causing the combustion gases to flow through the intermediate flow chamber, a more uniform heat distribution of the combustion gases is achieved. In addition, some heat is transferred from the combustion gases to the cooking cavity floor while the combustion gases are flowing through the intermediate flow chamber. Because this heat is supplied to the cooking cavity floor rather than to the top or sides of the cooking cavity, a more desirable cooking condition is achieved.
