Convection Cooking Appliance with Circular Air Flow System

A cooking appliance incorporating a convection cooking system comprising:

• an oven cavity defined by interconnected top, bottom, rear and first and second, opposing side walls, with the rear wall extending from the bottom wall to the top wall and defining an overall height of the oven cavity;
• a door mounted for selectively providing access to the oven cavity;
• a control panel having a plurality of control elements for selecting a desired cooking operation including a convection cooking mode;
• and
• a convection cooking system including a fan exposed to the inside of the oven cavity directly adjacent the rear wall, a motor having a drive shaft drivingly coupled to the fan such that operation of the motor causes the fan to rotate, and a convection cover having a first end portion, an intermediate portion and a second end portion, said convection cover being arranged in the oven cavity and mounted to the rear wall to form a tapering duct therebetween, said convection cover being formed with an intake in the first end portion at which the fan is mounted and a plurality of exhaust ports in the second end portion, said duct configured to receive a flow of air through the intake, said flow flowing at a first flow rate into the tapering duct to the plurality of exhaust ports and at a second flow rate which is greater than the first flow rate out of the plurality of exhaust ports into the oven cavity, said oven cavity being configured to guide the airflow along the opposing side wall toward a door of the oven cavity and redirect the flow of air along the door and the one side wall back to the intake thereby establishing a single, circular convection airflow pattern through the oven cavity.
