Abstract
An air flow system for a back fed common cavity oven wherein a path is provided for forcing moisture purging air into the cavity during microwave operation and wherein air is forced along the path during self-cleaning to prevent the very hot air in the cavity from flowing backwards along the path. Accordingly, parts and components along the path are not subjected to the very hot self-cleaning temperatures. The path may pass through the waveguide of the microwave feed apparatus and through an aperture into the cavity.
