Abstract
A convection based cooking apparatus with an insulating baffle to provide improved air-flow and isolation between a cooking chamber and a heating chamber. The heating chamber and the cooking chamber are positioned side by side, and separated by the insulating baffle. The insulating baffle is hollow for holding a liquid and includes an opening for emitting steam. An air passage exists between the heating chamber and the cooking chamber, in such a way that, heated air passes through the passage, flows over the insulating baffle to combine with the steam, and then into the cooking chamber. The air passage is located near the top of the heating chamber and the cooking chamber. As the air passes over the insulating baffle, the air is diffused throughout the cooking chamber and thereby uniformly distributed across a cooking surface within the cooking chamber.
