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.

A commercial oven, such as a combination oven providing steam and convection heating, may provide an equipment cabinet holding electronic equipment and having an external wall abutting other heating apparatus. The external wall includes an interior plenum through which air is circulated to provide compact virtual insulation from external heat sources.

A gas oven having a gas supplying passage to supply gas to a burner is provided. The gas oven includes an ON/OFF valve to open/close the gas supplying passage, and a flow rate modulating valve connected to the ON/OFF valve in series so as to change the cross-sectional area of a passage, thereby supplying a proper amount of gas to a cooking cavity in response to the change of a cooking area. When a cooking cavity is divided into individual cooking cavities while a divider is mounted, the flow rate modulating valve is open/closed at a smaller opening degree than the maximum operating degree, and thus may be able to prevent a cooking substance from being carbonized in the individual cooking cavities.

Disclosed herein is a gas oven including a body, a cooking space formed in the body, an air supply flow channel configured to connect the cooking space with an outside of the body to supply air to the cooking space, and a distribution unit configured to distribute or bend the air supplied through the air supply flow channel to supply the air to the cooking space. Through the distribution unit, it is possible to smoothly supply a primary air for mixing with gas and to smoothly supply a secondary air to an inside of the cooking space.

A cooking appliance for cooking food or other items is provided. The cooking appliance may include a main body having a cooking chamber; a fan cover provided on a back surface and forming an accommodation space separated within the cooking chamber, the fan cover having a suction port at a front of the fan cover and at least one exhaust port at a side of the fan cover; a heating element provided in the accommodation space to generate heat; a convection fan that generates an air circulation flow in the cooking chamber; and at least one guide vane, provided between a side surface of the cooking chamber and the at least one exhaust port, that guides a flow of air so that air discharged toward the side surface through the at least one exhaust port flows toward a front of the cooking chamber.

A gas oven and a control method thereof are The control method of the gas oven, that includes a cooking space that is divided into a first cooking space and a second cooking space by a removable divider, a burner that directly heats a cooked object accommodated in the first cooking space, and an auxiliary heater that heats air of the first cooking space, includes performing baking for the first cooking space when a baking mode for the first cooking space is selected among a plurality of cooking modes, wherein the baking may include operating the burner according to the comparison result of a temperature of the first cooking space and a first setting temperature, and operating the auxiliary heater according to the comparison result of the temperature of the first cooking space and a second setting temperature.

A gas-burning appliance includes a combustor and a flow guide device engaged with the combustor. The combustor has a gas outlet. The flow guide device includes a separator and two stop plates. The separator has an opening. Each of the stop plates is located at the opening, and a top edge thereof is higher than a top surface of the separator. The combustor is located below the separator with the gas outlet corresponding to a space between the stop plates. The flow guide device has at least one first air inlet, which is located below the separator, and communicates with the space between the stop plates. A gas fireplace includes a firebox, a translucent shield, and the gas-burning appliance. A separator divides the firebox into an air chamber, which receives the combustor, and a combustion chamber. Whereby, the visibility of flame and the combustion efficiency could be improved.

A commercial oven, such as a combination oven providing steam and convection heating, may provide an equipment cabinet holding electronic equipment and having an external wall abutting other heating apparatus. The external wall includes an interior plenum through which air is circulated to provide compact virtual insulation from external heat sources.

An appliance comprising a firebox, a first air duct and a room air chimney. During operation of the appliance heated room air adjacent to a viewing pane or the screen and heated room air from the first air duct is received within the chimney. The heated air within the chimney rises toward an open upper end causing the chimney to draw additional room air from adjacent to the viewing pane or screen.

According to one example, a convection oven comprises a cooking chamber having a front door and a rear door opposing the front door; a combustion chamber disposed below at least a portion of the cooking chamber; a side flue conduit configured to direct hot air from the combustion chamber to the cooking chamber; and a side sub-chamber with a convection fan configured to re-circulate at least a portion of the hot air within the cooking chamber, in which the side sub-chamber is disposed adjacent a side of the cooking chamber that is orthogonal to the front and rear door.
