Abstract

A home cooking appliance includes a housing, a cooking surface on a top of the housing, the cooking surface having an upper surface, and a rear vent trim on the top of the housing and at a rear side of the top of the housing. The rear vent trim has an upper surface that is substantially flush with the upper surface of the cooking surface. The rear vent trim includes an opening permitting air to exit from within the rear vent trim, and the rear vent trim directs the air away from a 90° angle with respect to the upper surface of the cooking surface.

First claim

What is claimed is:

1. A home cooking appliance comprising:
a housing;
a cooking surface on a top of the housing, the cooking surface having an upper surface; and
a rear vent trim on the top of the housing and at a rear edge of the top of the housing, the rear vent trim having an upper surface that is substantially flush with the upper surface of the cooking surface, the rear vent trim including an opening permitting air to exit from within the rear vent trim and a second opening permitting additional air to exit from within the rear vent trim, the rear vent trim directing the air away from a 90° angle with respect to the upper surface of the cooking surface, wherein the opening directs the air above the cooking surface and the second opening directs the additional air in a forward direction and toward the cooking surface,
wherein the cooking surface has a side surface, the side surface facing toward the rear vent trim, and wherein the second opening directs the additional air exiting the second opening at least one of onto the side surface of the cooking surface and below the upper surface of the cooking surface.

2. The home cooking appliance of claim 1 , wherein the rear vent trim includes a deflector concealed under an outer surface of the rear vent trim and disposed at a predetermined angle with respect to the upper surface of the rear vent trim, and
wherein the deflector directs the air away from the 90° angle with respect to the upper surface of the cooking surface before the air exits the opening in the rear vent trim.

3. The home cooking appliance of claim 1 , wherein the opening is in the upper surface of the rear vent trim.

4. The home cooking appliance of claim 1 , wherein the rear vent trim includes a second upper surface disposed at an angle other than a 90° angle with respect to the upper surface of the rear vent trim and on a side of the rear vent trim that is adjacent to the cooking surface, and
wherein the opening is formed in the second upper surface.

5. The home cooking appliance of claim 1 , wherein the opening comprises one of:
a first opening in fluid communication with a first air channel for guiding ambient kitchen air through the housing;
a second opening in fluid communication with a second air channel for exhausting cooling air drawn through the appliance; and
a third opening in fluid communication with a flue for exhausting flue gas from a cooking compartment within the housing.

6. The home cooking appliance of claim 1 , wherein the rear vent trim includes a plurality of openings that permit air to exit from within the rear vent trim while directing the air away from a 90° angle with respect to the upper surface of the cooking surface.

7. The home cooking appliance of claim 6 , wherein the upper surface of the rear vent trim includes the plurality of openings.

8. The home cooking appliance of claim 6 , wherein the rear vent trim includes a second upper surface disposed at an angle other than a 90° angle with respect to the upper surface of the rear vent trim and on a side of the rear vent trim that is adjacent to the cooking surface, and
wherein the plurality of openings are formed in the upper surface of the rear vent trim and the second upper surface of the rear vent trim.

9. The home cooking appliance of claim 6 , wherein the plurality of openings comprises two of:
a first opening in fluid communication with a first air channel for guiding ambient kitchen air through the housing;
a second opening in fluid communication with a second air channel for exhausting cooling air drawn through the appliance, and
a third opening in fluid communication with a flue for exhausting flue gas from a cooking compartment within the housing,
wherein each of the first air channel, the second air channel, and the flue are separate from each other such that the ambient kitchen air, the cooling air, and the flue gas are prevented from mixing with each other prior to exiting the plurality of openings of the rear vent trim.

10. The home cooking appliance of claim 6 , wherein the plurality of openings comprises:
a first opening in fluid communication with a first air channel for guiding ambient kitchen air through the housing,
a second opening in fluid communication with a second air channel for exhausting cooling air drawn through the appliance, and
a third opening in fluid communication with a flue for exhausting flue gas from a cooking compartment within the housing,
wherein each of the first air channel, the second air channel, and the flue are separate from each other such that the ambient kitchen air, the cooling air drawn, and the flue gas are prevented from mixing with each other prior to exiting the rear vent trim.

11. The home cooking appliance of claim 10 , wherein the rear vent trim includes a second upper surface disposed at an angle other than a 90° angle with respect to the upper surface of the rear vent trim and on a side of the rear vent trim that is adjacent to the cooking surface,
wherein the upper surface of the rear vent trim includes the first opening, and
wherein the second upper surface includes the second opening and the third opening.

12. The home cooking appliance of claim 5 , wherein at least two of the plurality of openings have different dimensions.

13. The home cooking appliance of claim 6 , wherein the plurality of openings comprises:
a first plurality of openings in fluid communication with a first air channel for guiding ambient kitchen air through the housing;
a second plurality of openings in fluid communication with a second air channel for exhausting cooling air drawn through the appliance; and
a third plurality of openings in fluid communication with a flue for exhausting flue gas from a cooking compartment within the housing.

14. The home cooking appliance of claim 13 , wherein the first plurality of openings, the second plurality of openings, and the third plurality of openings have different dimensions.

15. A home cooking appliance comprising:
a housing;
a cooking surface on a top of the housing, the cooking surface having an upper surface; and
a rear vent trim on the top of the housing and at a rear edge of the top of the housing, the rear vent trim having an upper surface that is substantially flush with the upper surface of the cooking surface, the rear vent trim including an opening permitting air to exit from within the rear vent trim and a second opening permitting additional air to exit from within the rear vent trim, the rear vent trim directing the air away from a 90° angle with respect to the upper surface of the cooking surface,
wherein the opening directs the air above the cooking surface and the second opening directs the additional air in a forward direction toward the cooking surface,
wherein the rear vent trim includes a second upper surface having the second opening permitting the additional air to exit from within the rear vent trim,
wherein the rear vent trim directs the air exiting from within the rear vent trim through the opening in the upper surface of the rear vent trim away from the 90° angle with respect to the upper surface of the cooking surface and above the upper surface of the cooking surface, and
wherein the rear vent trim directs the additional air exiting from within the rear vent trim through the second opening in the second upper surface of the rear vent trim away from the 90° angle with respect to the upper surface of the cooking surface and below the upper surface of the cooking surface.

16. The home cooking appliance of claim 1 , wherein the rear vent trim extends across th
