  • Publication number: 20040177845
    Abstract: 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.

  • Publication number: 20040177842
    Abstract: A gas cooking appliance includes at least one oven cavity which is coated with a heat resistant material, preferably porcelain. The cooking appliance includes a gas broil element and an associated baffle, as well as a gas igniter, arranged atop the oven cavity. The baffle is provided with one or more openings above the igniter for ventilation purposes. Each opening is preferably defined by a louver. With the inclusion of the louvered opening, enhanced combustion is assured and any potential crazing zone of the oven cavity is shifted to a position wherein, should any heat resistant material chip off due to heat from the igniter, the material will be blocked from falling into any food support zone of the oven cavity.

  • Publication number: 20040177840
    Abstract: 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.

  • Patent number: 6761159
    Abstract: 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.

  • Patent number: 6758206
    Abstract: 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.
