Airflow system for a convection oven

A cooking appliance comprising:

• an oven cavity having top, bottom, rear, and opposing side walls that collectively define a cooking chamber;
• a door mounted for movement relative to the oven cavity for selectively closing the cooking chamber;
• a convection fan for establishing a convection airflow within the cooking chamber;
• a heating element for raising a temperature of the convection airflow, said heating element including first and second sections symmetrically disposed about the convection fan substantially parallel to and downstream of the convection fan, each of said first and second sections having at least three lobes and four 180° turns, while establishing a thin profile heating unit;
• and
• a convection fan cover including a main body portion having an inlet portion for receiving the convection airflow from the cooking chamber and an outlet portion for directing the convection airflow back into the cooking chamber.

A cooking appliance comprising:

• an oven cavity having top, bottom, rear, and opposing side walls that collectively define a cooking chamber;
• a door mounted for movement relative to the oven cavity for selectively closing the cooking chamber;
• a convection fan for establishing a convection airflow within the cooking chamber, said convection fan having an innermost diametric portion and an outermost diametric portion;
• a heating element for raising a temperature of the convection airflow;
• and
• a convection fan cover including a main body portion having an inlet portion for receiving the convection airflow from the cooking chamber and an outlet portion for directing the convection airflow back into the cooking chamber, said outlet portion including an angled louver and a trip edge portion which cooperate to alter a direction of the convection airflow from being substantially parallel to the main body portion to being substantially perpendicular to the main body portion.
