Abstract
A cooking appliance includes a frame having a bottom wall for supporting heating elements and a peripheral side portion that extends from and about an outer periphery of the bottom wall so as to define a chassis upon which is arranged a cooktop. The peripheral side portion includes a plurality of openings that lead into the chassis. A control box is mounted in the chassis for housing control elements and associated electronics. The control box includes a plurality of side walls, with at least one of the side walls being provided with a vent which opens into the chassis. A fan is mounted within the chassis wherein, when the fan is activated, a cooling airflow is developed, with a first portion being drawn directly into the chassis, while a second portion first enters the control box housing before being directed into the chassis. A cover can be disposed beneath the chassis to guide and disperse the airflow.
