Abstract

A double oven range appliance and a gas burner and floor assembly for an oven appliance are provided. The gas burner and floor assembly includes a cooking chamber bottom panel with a projection defining a plurality of openings. A gas burner is positioned above the plurality of openings. A floor panel is positioned below the cooking chamber bottom panel. An insulation panel is mounted to the floor panel such that the insulation panel is disposed below the plurality of openings. The gas burner and floor assembly can assist with limiting heat transfer along a vertical direction while also providing a suitable flow of air at the gas burner.

First claim

What is claimed is:

1. A double oven range appliance that defines a vertical direction and a transverse direction that are perpendicular to each other, comprising:
a cabinet that extends between a top portion and a bottom portion along the vertical direction, the cabinet having an upper cooking chamber positioned adjacent the top portion of the cabinet and a lower cooking chamber positioned adjacent the bottom portion of the cabinet;
a baking gas burner; and
a floor assembly positioned at the bottom portion of the cabinet, the floor assembly comprising
a cooking chamber bottom panel having an upper surface and a projection, the projection extending away from the upper surface of the bottom panel along the vertical direction, the projection including a top wall and a pair of sidewalls, the projection defining a plurality of openings that are spaced apart from each other along the transverse direction, the plurality of openings defined through each sidewall of the pair of sidewalls, the baking gas burner positioned at the plurality of openings defined through the top wall such that the baking gas burner is positioned above the plurality of openings along the vertical direction,wherein the plurality of openings defined through each sidewall are directed towards the upper surface of the bottom panel as a plurality of thermal breaks;
a floor panel positioned below the cooking chamber bottom panel along the vertical direction such that the floor panel and the cooking chamber bottom panel define a baffle therebetween; and
an insulation panel mounted to the floor panel such that the insulation panel is disposed below the plurality of openings along the vertical direction.

2. The double oven range appliance of claim 1 , wherein the floor panel and the cooking chamber bottom panel are spaced apart from each other such that the baffle has a height along the vertical direction, the height of the baffle being less than about one half of an inch.

3. The double oven range appliance of claim 1 , wherein the floor panel includes a plurality of supports, the cooking chamber bottom panel positioned on distal end portions of the plurality of supports in order to support the cooking chamber bottom panel.

4. The double oven range appliance of claim 1 , wherein the double oven range appliance defines a lateral direction, the vertical, transverse and lateral directions being mutually perpendicular, further comprising a pair of insulation panels, each insulation panel of the pair of insulation panels positioned on the upper surface of the cooking chamber bottom panel and spaced apart from each other along the lateral direction such that each insulation panel of the pair of insulation panels is positioned on opposite lateral sides of the cooking chamber bottom panel.

5. The double oven range appliance of claim 1 , wherein the floor assembly further comprises a flame spreader, the flame spreader positioned above the baking gas burner along the vertical direction, the flame spreader and the floor panel spaced apart from each other along the vertical direction such that the floor assembly has a total height along the vertical direction, the total height of the floor assembly being less than about two inches.

6. The double oven range appliance of claim 1 , Wherein the double oven range appliance defines a lateral direction, the vertical, transverse and lateral directions being mutually perpendicular, the floor panel and the cooking chamber bottom panel defining inlet openings at opposite lateral side portions of the floor assembly and at a back portion of the floor assembly.

7. The double oven range appliance of claim 6 , wherein the inlet openings are configured for permitting a flow of air into the baffle with the baffle directing the flow of air to the plurality of openings and the flow of air exiting the plurality of openings at the baking gas burner.

8. The double oven range appliance of claim 1 , wherein the plurality of openings define a total opening area and the baking gas burner has a power output, a ratio of the power output of the baking gas burner and the total opening area of the plurality of openings being less than about four thousand British Thermal units per hour per inch squared.

9. The double oven range appliance of claim 1 , further comprising a pair of wings position on opposite lateral sides of baking gas burner, wherein each wing extends to a position below the baking gas burner and above the plurality of openings defined through each sidewall.

10. A gas burner and floor assembly for an oven range appliance, the gas burner and floor assembly defining a vertical direction, a lateral direction and a transverse direction, the vertical, lateral and transverse directions being mutually perpendicular, the gas burner and floor assembly comprising:
a baking gas burner extending between a first end portion and a second end portion along the transverse direction; and
a floor assembly comprising
a cooking chamber bottom panel having an upper surface and a projection, the projection extending away from the upper surface of the bottom panel along the vertical direction, the projection including a top wall and a pair of sidewalls,the projection defining a plurality of openings that are spaced apart from each other along the transverse direction, the plurality of openings including a plurality of opening defined through the top wall and a plurality of openings defined through each sidewall of the pair of sidewalls,the baking gas burner positioned above the plurality of openings along the vertical direction, the plurality of openings dispersed along the transverse direction between about the first and second end portions of the baking gas burner, wherein the plurality of openings defined through each sidewall are directed toward the upper surface of the bottom panel as a plurality of thermal breaks;
a floor panel positioned below the cooking chamber bottom panel along the vertical direction such that the floor panel and the cooking chamber bottom panel define a baffle therebetween; and
an insulation panel mounted to the floor panel such that the insulation panel is disposed below the plurality of openings along the vertical direction.

11. The gas burner and floor assembly of claim 10 , wherein the floor panel and the cooking chamber bottom panel are spaced apart from each other such that the baffle has a height along the vertical direction, the height of the baffle being less than about one half of an inch.

12. The gas burner and floor assembly of claim 10 , wherein the floor panel includes a plurality of supports, the cooking chamber bottom panel positioned on distal end portions of the plurality of supports in order to support the cooking chamber bottom panel.

13. The gas burner and floor assembly of claim 10 , further comprising a pair of insulation panels, each insulation panel of the pair of insulation panels positioned on the upper surface of the cooking chamber bottom panel and spaced apart from each other along the lateral direction such that each insulation panel of the pair of insulation panels is positioned on opposite lateral sides of the cooking chamber bottom panel.

14. The gas burner and floor assembly of claim 10 , wherein the floor assembly further comprises a flame spreader, the flame spreader positioned above the baking gas burner along the vertical direction, the flame spreader and the floor panel spaced apart from each other along the vertical direction such that the floor assembly has a total height along the vertical direction, the total height of the floor assembly being less than about two inches.

15. The gas burner and
