Convection Cooking Appliance with Circular Air Flow System

摘要

A circular air flow pattern is created in a small oven cavity having a convection system including a convection cover which is mounted to and defines a duct in combination with a rear wall of the oven cavity. The convection cover includes an intake at one end portion arranged adjacent a first side wall of the oven cavity and a plurality of exhaust openings formed in another end portion arranged adjacent a second side wall of the oven cavity, with the convection cover progressively tapering through multiple sections. The rear wall can include an elongated recess over which the convection cover extends in forming the duct.

主权项

1. A method of recirculating air in an oven cavity of a cooking appliance comprising:
drawing a flow of air from adjacent one side wall of the oven cavity into an intake of a convection cover mounted to a rear wall of the oven cavity; directing the flow of air through a tapering duct defined between the convection cover and the rear wall to a plurality of exhaust ports provided in the convection cover adjacent an opposing side wall of the oven cavity; directing the flow of air out of the plurality of exhaust ports and along the opposing side wall toward a door of the oven cavity; and re-directing 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.
