An oven appliance includes a cabinet. A chamber is defined within the cabinet for receipt of food items for cooking. The oven appliance also includes a gas burner positioned proximate to a bottom portion of the chamber with a combustion products guide structure positioned and oriented to guide combustion products from the gas burner to an outlet proximate a back wall of the chamber.

A burner assembly for an oven appliance, the oven appliance defining a vertical direction, a lateral direction, and a transverse direction and including a cooking chamber, the burner assembly including a gas burner provided in the cooking chamber, the gas burner defining a clean air port, and a shutter housing attached to a first end of the gas burner, the shutter housing defining an air inlet in fluid communication with the clean air port, and wherein the air inlet is positioned below the clean air port along the vertical direction.

An oven appliance includes a cabinet with a chamber for receipt of food items for cooking defined therein. The oven appliance also includes a gas burner positioned proximate to a top portion of the chamber. The oven appliance may also include a low-power electric heating element. The gas burner may be the only combustive heat source for the chamber. The oven appliance includes an electric power supply that may consist of a twenty amp or less circuit.

An oven appliance includes a cabinet with a chamber is defined within the cabinet for receipt of food items for cooking. The oven appliance also includes a gas burner positioned proximate to a bottom portion and/or a back wall of the chamber. A natural convection flow path is defined through the chamber. The natural convection flow path extends from an origin at the gas burner to a top wall of the chamber. The oven appliance further includes a convection fan positioned along the natural convection flow path above the gas burner and below the top wall. The convection fan is positioned and configured to divert combustion products generated by the gas burner from the natural convection flow path along a forced convection flow path towards a center of the chamber when the convection fan is activated.

An oven appliance includes a cabinet defining a vertical direction, a lateral direction, and a transverse direction. The vertical, lateral, and transverse directions are mutually perpendicular. The cabinet comprising a front portion spaced apart from a back portion along the transverse direction and a left side spaced apart from a right side along the lateral direction. The oven appliance also includes a chamber defined within the cabinet for receipt of food items for cooking. A broil heating element is positioned proximate to a bottom portion of the chamber.

An oven appliance includes a cabinet with a chamber defined within the cabinet for receipt of food items for cooking. The oven appliance also includes a gas burner positioned within the cabinet outside of the chamber. The gas burner is in thermal communication and in fluid communication with the chamber by a direct flow path from the gas burner to the chamber.

A cooking appliance having a broiler may include a housing defining an upper compartment above the broiler and a rear compartment behind the broiler. A gas mixing pipe extends through the upper compartment to the rear compartment via an opening in an interior wall of the housing. A cover is removably coupled to an outer surface of the interior wall, such that opposing U-shaped slots of the two cover portions collectively form an aperture that conforms to an outer periphery of the gas mixing pipe. Accordingly, the cover blocks one or more gaps in the interior wall, such that the cover is configured to prevent gases from passing into the rear compartment through the gaps.

An oven appliance includes a cooking chamber defined at least in part by a bottom wall having an outlet port defined therein, wherein the outlet port defines a virtual boundary projected in the vertical direction, a burner positioned below the bottom wall proximate the outlet port and outside of the virtual boundary of the outlet port, and a burner shield. The burner shield includes a cover portion positioned directly over the burner, and a first extension having a first edge connected to the cover portion and a second edge opposite the first edge, wherein the first extension extends toward the outlet port.

A cooking appliance is provided. The cooking appliance may include a convection fan installed in a cooking chamber; a fan motor installed outside of the cooking chamber and configured to rotate the convection fan; a cooling fan installed outside of the cooking chamber and rotated by the fan motor to generate air currents to flow to the fan motor; a duct that forms a passage that connects an inside of the cooking chamber and the outside of the cooking chamber, wherein an opening in the duct is opened toward the cooling fan; and a blocking member installed outside of the cooking chamber and configured to block a path of air flow from the opening to the cooling fan.

An oven according to the present invention includes: a body having a cooking chamber provided in the body; a heat source in the cooking chamber to heat the cooking chamber; and a drawer device under the body, and including: a drawer case having one or more holes in the upper surface of the drawer case; and a plate covering the one or more holes and forming a gap between the plate and the upper surface, wherein the gap is configured to allow a flow path through the gap for air in the drawer case to be supplied to the heat source through the one or more holes.
