Abstract

An air baffle unit includes a major housing wall extending in first and second directions to define an exterior side and an interior side, two upper corner output vent openings, first and second laterally opposed side vent openings, and an air intake opening arrangement defined within an intake area along the major housing wall and extending therealong in the first and second directions. The air intake opening arrangement is defined in an intake area and includes first and second pluralities of intake vents positioned within respective first and second open areas of the intake area with first and second closed areas extending between the first and second open areas. The first and second open areas and first and second closed areas each positioned within respective quarters of the intake area. The open areas are displaced relative to each other in both the first direction and the second direction.

First claim

What is claimed is:

1. An air baffle unit for use within an oven, the baffle unit comprising:
a major housing wall extending in first and second directions to define an exterior side and an interior side;
two upper corners output vent openings defined on top left and right corners of the baffle unit extending from an upper edge of the major housing wall on the interior side thereof;
first and second laterally opposed side vent openings defined along respective lateral sides of the baffle unit extending from respective side edges of the major housing wall on the interior side thereof; and
an air intake opening arrangement defined within an intake area along the major housing wall and extending therealong in the first and second directions, the air intake opening arrangement including first and second pluralities of radially-spaced, concentric arced vent openings defining respective first and second open areas of the intake area by each vent opening extending circumferentially between sequential boundaries of the respective open area, with first and second closed areas extending uninterrupted and completely between the first and second open areas, the first and second open areas and the first and second closed areas each occupying a respective quarter of an entirety of the intake area, the open areas being displaced relative to each other in both the first direction and the second direction.

2. The air baffle unit of claim 1 , wherein first and second axes extending, respectively, in the first and second directions, divide the intake area into the respective quarters, the first and second axes intersecting adjacent a geometric center of the major housing wall.

3. The air baffle unit of claim 2 , wherein the first and second open areas are on opposite sides of both the first and second axes and extend generally away from an intersection of the axes.

4. The air baffle unit of claim 2 , wherein the intake area defines a generally circular area disposed around the intersection of the axes.

5. The air baffle unit of claim 2 , wherein the open areas of the intake area are open between the exterior and interior sides of the major housing wall, a fan being disposed on the interior side underlying the intake area.

6. The air baffle unit of claim 5 , wherein:
the fan operating within the two open areas draw air in from the exterior through the open areas and directs air to the first and second lateral side vent openings and to the first and second upper corner vent openings.

7. The air baffle unit of claim 1 , wherein each of the quarters is defined by curved boundary lines.

8. The air baffle unit of claim 7 , wherein each of the quarters is propeller-shaped.

9. A convection unit for a gas oven, comprising:
an air baffle unit, including:
a major housing wall extending in first and second directions to define an exterior side and an interior side;
two upper output vent openings defined on top left and right corners of the baffle unit extending from an upper edge of the major housing wall on the interior side thereof;
first and second laterally opposed side vent openings defined along respective lateral sides of the baffle unit extending from respective side edges of the major housing wall on the interior side thereof; and
an air intake opening arrangement defined within an intake area along the major housing wall and extending therealong in the first and second directions, the air intake opening arrangement including first and second pluralities of radially-spaced, concentric arced vent openings defining respective first and second open areas of the intake area by each vent opening extending circumferentially between sequential boundaries of the respective open area, with first and second closed areas extending uninterrupted and completely between the first and second open areas, the first and second open areas and the first and second closed areas each occupying a respective quarter of an entirety of the intake area, the open areas being displaced relative to each other in both the first direction and the second direction; and

a fan disposed within the air baffle unit and including a plurality of blades extending radially from a first axis.

10. The convection unit of claim 9 , wherein second and third axes extend the first and second directions, respectively, and divide the intake area into the respective quarters, the second and third axes intersecting along the first axis.

11. The convection unit of claim 10 , wherein the intake area defines a generally circular area disposed around the first axis.

12. The convection unit of claim 10 , wherein the open areas of the intake area are open between the exterior and interior sides of the major housing wall, the fan being disposed on the interior side underlying the intake area.

13. The convection unit of claim 12 , wherein:
the fan underlying the open areas draws air in from the exterior through the open areas and directs air to the first and second side vent openings and to the first and second upper corner vent openings.

14. The convection unit of claim 9 , wherein each of the quarters is defined by curved boundary lines.

15. The convection unit of claim 14 , wherein each of the quarters is propeller-shaped.

16. An oven, comprising:
an interior cavity including an opening, a rear wall opposite the opening, and a floor extending between the opening and the rear wall; and
an air baffle unit including:
a major housing wall extending in first and second directions to define an exterior side and an interior side;
two upper output vent openings defined on top left and right corners of the baffle unit extending from an upper edge of the major housing wall on the interior side thereof;
first and second laterally opposed side vent openings defined along respective lateral sides of the baffle unit extending from respective side edges of the major housing wall on the interior side thereof; and
an air intake opening arrangement defined within an intake area along the major housing wall and extending therealong in the first and second directions, the air intake opening arrangement including first and second pluralities of radially-spaced, concentric arced vent openings defining respective first and second open areas of the intake area defining by each vent opening extending circumferentially between sequential boundaries of the respective open area, with first and second closed areas extending uninterrupted and completely between the first and second open areas, the first and second open areas and the first and second closed areas each occupying a respective quarter of entirety of the intake area, the open areas being displaced relative to each other in both the first direction and the second direction.

17. The oven of claim 16 , wherein the air baffle unit is included within a convection unit disposed within the interior cavity of the oven and further including:
a fan having a plurality of blades extending radially from an axis.

18. The oven of claim 17 , wherein the axis of the fan extends from the rear wall generally normal thereto and the air baffle unit is mounted on the rear wall.

19. The oven of claim 18 , further comprising:
a burner unit having a heat output extending from the floor adjacent the rear wall, the fan drawing air through the open areas of the intake areas and distributing air flow among upper corners and side vent openings.

20. The oven of claim 16 , wherein:
the upper corners output vent openings of the air baffle unit are defined between the upper e
