Abstract

A convection oven having multiple airflow patterns within a cooking chamber during a baking cycle. In one embodiment, at least one reversible blower wheel rotatable at varying speeds produces separate airflow states to create multiple airflow patterns within the cooking chamber during a baking cycle. In another preferred embodiment, at least one adjustable airflow control surface mounted within the cooking chamber creates multiple airflow patterns within the cooking chamber during the baking cycle.
