1. A gas burner device comprising:
an orifice holder including an orifice; and
a burner body including four venturi tubes arranged to receive a gas from the orifice, a burner port arranged to discharge the gas supplied through four venturi tubes, and four gas chambers arranged to guide the gas that passed the venturi tubes to the burner port, the gas chambers respectively corresponding to the venturi tubes and partitioned from each other,
wherein each of the venturi tubes comprises:
a venturi inlet through which the gas that is jetted from the orifice flows in,
a venturi outlet through which the gas flowing in through the venturi inlet is discharged, and
an acceleration part including a smaller inner diameter than the venturi inlet and the venturi outlet, wherein the smaller inner diameter is constant along a length of the acceleration part such that the acceleration part has a cylindrical shape,
wherein each of the gas chambers has a shape of a sector of a circle, and the shape of the sector of the circle includes an arc of the circle corresponding to an outer circumferential surface of the burner body on which the burner port is arranged, and a guide wall configured to guide the gas discharged from the venturi outlet toward the burner port,
wherein each of the gas chambers gradually expands as it extends from a portion closest to a center of the burner body to the burner port,
wherein the guide wall has a substantially constant height along its entire length such that a top surface of the guide wall is substantially planar, and
wherein the venturi outlet is spaced apart from the guide wall and the burner port, and the venturi outlet is arranged closer to a center of the respective gas chamber than to the arc of the respective gas chamber.
