Abstract

A convection steam cooking device utilizes forced recirculation of gases along a primary recirculation path that extends through a steam chamber so that gases from the cooking cavity flow through the steam chamber and are subjected to a “steam bath” that alters the gases by adding heat and/or moisture. The cooking device includes a cooking cavity, a fan, a steam chamber disposed beneath the cooking cavity with a lower pool area for holding water and an upper steam collecting area disposed directly above the pool area, and a removable baffle disposed between the cooking cavity and the steam chamber with a perforated section remote from the fan and disposed at an upward angle. The primary forced recirculation path extends from the main cooking cavity, through the baffle, substantially across the steam collecting area, through a duct to the fan, and back to the main cavity.
