Oven appliances with improved gas burner assembly

Abstract

An oven appliance incudes a cabinet extending between a first side portion and a second side portion along the lateral direction. The cabinet also extends between a top portion and a bottom portion along the vertical direction. The cabinet defines a cooking chamber. A broil gas burner assembly is positioned at a back wall of the cooking chamber and is in direct thermal communication with the cooking chamber. The broil gas burner assembly includes a burner tube extending in the lateral direction. The burner tube defines a series of outlets dispersed along the lateral direction. The series of outlets are positioned on a top of the burner tube in the vertical direction. An air deflector extends away from the burner tube in one or more of the vertical direction and the transverse direction.
