An oven has a cooking cavity and a gas heating element provided at a lower portion of the cooking cavity and a low power electric heating element provided at an upper portion of the cooking cavity. Thermal radiation provided to the upper portion by the electric heating element combined with reflected thermal radiation provided from the gas heating element is enough to broil a food item in a predetermined broiling cycle of the oven.

A cooking apparatus includes a frame configured to form a cooking chamber; a burner cover provided inside the frame and configured to form a combustion chamber; a burner accommodated in the combustion chamber; a fan provided at an outside of the burner cover in the frame; and a fan cover configured to cover the fan and the burner cover.

A cooking device includes a frame forming a cooking chamber; a door opening and closing the cooking chamber; a burner cover disposed in the cooking chamber; and a burner located in the burner cover, the burner generating a flame, wherein the burner cover is provided with a first hole providing a path through which air flows, and the frame is provided with a second hole communicating with the first hole, the second hole providing a path through which the air flows.

A cooking device includes an outer case configured to form an exterior thereof; a cavity provided in the outer case and configured to form a cooking space in which food is cooked; a burner assembly installed in the cavity and configured to cook the food by burning a gas; and an air guide unit which is in communication with the burner assembly and exposes to an outside of the outer case so that air outside the outer case is guided to the burner assembly.

A method, system, and apparatus for roasting product such as chile comprises an inner roasting chamber, an exterior housing, housing the inner roasting chamber, a fixed engagement between the inner roasting chamber and the exterior housing on a burner end of the roaster system, an end cap fitting on a product exit end of the roaster system such that the inner roasting chamber can expand and contract within the exterior housing, a conveyor assembly comprising a conveyor belt, a motor configured to drive the conveyor belt, and a tensioning mechanism to adjust tension in the conveyor belt, and a gas distribution assembly connected to at least one burner.

A cooking device includes a frame to form a cooking chamber; a burner cover disposed inside the frame and to form a combustion chamber and have an air inlet hole in which air is introduced; a burner in the combustion chamber; an ignition device in the combustion chamber and to have an ignition unit for igniting a mixed gas discharged from the burner; and a flow guide to change a flow direction of the air which is introduced through the air inlet hole at a side of the ignition unit, wherein the flow guide is formed as a portion of the burner cover protrudes to the combustion chamber by forming.

A cooking apparatus includes a frame configured to form a cooking chamber; a burner cover provided inside the frame and configured to form a combustion chamber; a burner accommodated in the combustion chamber; a fan provided at an outside of the burner cover in the frame; and a fan cover configured to cover the fan and the burner cover.

A cooking device includes a frame forming a cooking chamber; a door opening and closing the cooking chamber; a burner cover disposed in the cooking chamber; and a burner located in the burner cover, the burner generating a flame, wherein the burner cover is provided with a first hole providing a path through which air flows, and the frame is provided with a second hole communicating with the first hole, the second hole providing a path through which the air flows.

A cooking device including a frame that defines a cooking chamber, a burner cover provided in the frame to form a combustion chamber and includes an opening for flowing air, a burner provided inside the combustion chamber, and a barrier member provided between the burner cover and the frame in order to prevent heat of air discharged from the combustion chamber from being delivered to the frame.

Aspects and features of a burner for a cooking appliance include a first plate defining flame ports arranged in flow-sharing groups around a periphery of a combustion surface and a second plate coextensive with the first plate. Each plate is contoured so that the plates define an annular void within the burner. The annular void is fluidly coupled to the flame ports. In some aspects, each flow-sharing group includes clusters of flame ports, with each cluster including flame ports of two different diameters. The plates can each be made using the same tool such as a die, stamp, or mold, and the burner can be sized and installed in a cooking appliance so that it extends to cover a large portion of a wall of the cooking cavity of the appliance.
