Abstract
A convection cooking appliance includes a convection fan for establishing a convection airflow which is heated by a heating element including first and second sections that are symmetrically disposed about the convection fan substantially parallel to and downstream of the convection fan. Each of the first and second sections is formed so as to include at least three lobes and four 180° turns, while establishing a thin profile heating element. A convection fan cover extends across the convection fan and includes a main body portion having an outlet portion for directing the convection airflow into a cooking chamber of the appliance. The outlet portion includes an angled louver and a trip edge portion. The angled louver and trip edge portion cooperate to alter a direction of the convection airflow from being substantially parallel to the main body portion to being substantially perpendicular the main body portion.
