Abstract
An oven includes an interior cavity and a convection heating system for developing a flow of heated air within the interior cavity. The convection heating system includes a plurality of fans to provide a plurality of airflows, and a single convection heating element for heating the plurality of airflows. A shroud is arranged in covering relationship over the convection heating system and includes at least one intake aperture, and a plurality of exhaust apertures for discharging air from the plurality of fans back into the interior cavity. A baffle is located within the shroud and generally between adjacent ones of the plurality of fans. The baffle inhibits mixture of the airflows of each of the fans within the shroud. In one example, a first fan provides a first airflow, a second fan providing a second airflow, and the baffle inhibits mixture of the first and second airflows within shroud.
