A gas cooking appliance includes a low profile gas burner assembly positioned within an oven cavity. The low profile gas burner assembly, formed from a tubular member having a defined diameter, includes a first end, defining an inlet portion, interconnected with a second end, defining an outlet portion, through an intermediate portion. In accordance with the invention, the intermediate portion maintains a vertically spaced relationship between the inlet portion and outlet portion from about 1.0 to 3.33 times the diameter of the tubular member, preferably about 1.33 to 2.66 times the diameter and, most preferably, approximately twice the diameter of the tubular member.

Low profile gas burner for a cooking appliance

A cooking appliance includes a gas burner module having a base structure upon which is secured at least a gas burner element and a gas orifice defining member in a predetermined alignment. The base structure is preferably formed from stamped steel. The burner module also preferably includes a gas igniter. The gas burner module is adapted to be mounted to heat an oven cavity of the cooking appliance. With this arrangement, tolerance build-up leading to misalignment between critical components is greatly reduced thereby improving manufacturing and combustion repeatability, as well as enhanced field replacement. In this manner, the cooking appliance will consistently operate within prescribed agency limitations.

Gas burner module for a cooking appliance

A cook appliance in the form of a range having upper and lower oven is provided with an exhaust system including an exhaust duct for the lower oven which extends through an exhaust duct for the upper oven. Each of the exhaust ducts leads to an exhaust air box which defines an exhaust outlet for the appliance. Preferably, the exhaust duct for the lower oven has associated therewith an extension sleeve which divides the exhaust air box into separate exhaust zones for the upper and lower ovens. Provisions are made to dilute and/or cool exhaust gases flowing through the ducts prior to the exhaust gases existing the appliance.

Exhaust cooling system for a cooking appliance

A range includes a cabinet, defined by at least a front, side, bottom and top portions, as well as upper and lower oven cavities each having a respective gas burner assembly. At least one passageway is formed to create an airflow path enabling a portion of an ambient airflow introduced into the cabinet to reach the gas burner assemblies of the upper and lower oven cavities for combustion purposes, preferably through natural convection, while the remaining portion of the airflow passes over and cools portions of the range. In a preferred form of the invention, insulation is maintained in a desired position below a respective oven cavity by a holder through which the airflow passes to the burner assembly.

Cooling and combustion airflow supply system for a gas range

A gas cooking appliance, having burner units mounted on an upper cooktop and an oven cavity arranged below the burner units, incorporates a fan for generating a flow of cooling air within the appliance, with the cooling air extending along an at least back and top wall portions of the oven cavity. The cooling air exits the appliance through a frontal gap formed between a door of the oven cavity and an upper frontal portion of the appliance. The burner units have associated combustion air inlets which are isolated from the flow of cooling air by being disposed in a chamber formed by sealing an isolation pan beneath the cooktop. The cooktop is formed with a plurality of openings for permitting a flow of combustion air to be drawn into the chamber for mixing with a regulated flow of combustion gas. With this arrangement, the gas burner units are isolated from the flow of cooling air within the appliance to enhance the operation of the burner units, particularly during low or simmer settings.

Gas cooking appliance with isolated combustion and cooling air flows

A sealed gas burner assembly provides fast spark ignition of the primary air/gas mixture by supporting the electrode in an electrically insulative member that is disposed in a fluid-tight sealing engagement through the electrode aperture of a burner head, whereby ignition is facilitated by providing an ignition port directly adjacent an exterior terminal end portion of the electrode. The burner head has a low profile defined partly by a circumferential curved sidewall which eliminates turbulence in secondary airflow to the burner ports during high burner rates. A venturi tube providing the primary air/gas mixture to the burner and ignition is fully contained within an internal chamber of the burner head. The assembly is detachably secured to the burner opening of a range top through a twist lock engagement therewith, and is also provided with a seal to prevent spillovers from leaking between the assembly and the range top into the burner box.
