Abstract

A home cooking appliance includes a housing having a cooktop surface on a top of the housing, a burner on the cooktop surface, a cooking grate disposed above the burner, a cooking compartment in the housing, an oven flue that exhausts air from the cooking compartment, and a flue gas air diverter configured to divert the air exiting from the oven flue under a portion of the cooking grate.

First claim

What is claimed is:

1. A home cooking appliance comprising:
a housing having a cooktop surface on a top of the housing;
a burner on the cooktop surface;
a cooking grate disposed above the burner;
a cooking compartment in the housing;
an exhaust channel that exhausts air from the cooking compartment out of the housing; and
a flue gas air diverter configured to divert the air exiting the housing from the exhaust channel under a portion of the cooking grate,
wherein the flue gas air diverter is on a plate portion, the plate portion being coupled to a rear wall of the housing without direct physical contact between the plate portion and the rear wall, and including an emboss facing the rear wall, the emboss being spaced from the rear wall.

2. The home cooking appliance of claim 1 , further comprising:
a rear vent trim at a rear side of the top of the housing, the rear vent trim having at least one opening in communication with the exhaust channel, the at least one opening configured to permit the air exiting the housing from the exhaust channel to flow under the portion of the cooking grate.

3. The home cooking appliance of claim 2 , wherein the rear vent trim has a front surface facing toward a front of the housing, and
wherein the at least one opening of the rear vent trim is formed in the front surface of the rear vent trim.

4. The home cooking appliance of claim 3 , further comprising:
a cooling fan,
wherein the rear vent trim has an upper surface including a vent opening for exhausting cooling air from the cooling fan upward from the rear vent trim.

5. The home cooking appliance of claim 1 , wherein the flue gas air diverter is positioned on a surface of a rear wall of the housing that faces the exhaust channel.

6. The home cooking appliance of claim 1 , wherein the flue gas air diverter is coupled to a rear wall of the housing without direct physical contact between the flue gas air diverter and the rear wall.

7. The home cooking appliance of claim 6 , further comprising:
a fastener for mounting the flue gas air diverter to the rear wall of the housing without direct physical contact between the flue gas air diverter and the rear wall.

8. The home cooking appliance of claim 1 , further comprising:
a fastener for mounting the flue gas air diverter to the rear wall of the housing without direct physical contact between the flue gas air diverter and the rear wall.

9. The home cooking appliance of claim 4 , wherein the flue gas air diverter is disposed at an angle with respect to the upper surface of the rear vent trim.

10. The home cooking appliance of claim 1 , further comprising:
a second exhaust channel that exhausts air from the cooking compartment; and
a second flue gas air diverter configured to divert the air exiting from the second exhaust channel under a second portion of the cooking grate.

11. The home cooking appliance of claim 10 , wherein the exhaust channel is spaced from the second exhaust channel.

12. The home cooking appliance of claim 10 , further comprising:
a rear vent trim at a rear side of the top of the housing, the rear vent trim having a plurality of openings,
wherein a first opening of the plurality of openings is in communication with the exhaust channel, the first opening configured to permit the air exiting from the exhaust channel to flow under the portion of the cooking grate, and
wherein a second opening of the plurality of openings is in communication with the second exhaust channel, the second opening configured to permit the air exiting from the second exhaust channel to flow under the second portion of the cooking grate.

13. The home cooking appliance of claim 12 , wherein the rear vent trim has a front surface facing toward a front of the housing, and wherein the first opening and the second opening of the rear vent trim are formed in the front surface of the rear vent trim.

14. The home cooking appliance of claim 13 , further comprising:
a cooling fan,
wherein the rear vent trim has an upper surface including a plurality of vent openings for exhausting cooling air from the cooling fan upward from the rear vent trim.

15. The home cooking appliance of claim 1 , wherein the flue gas air diverter includes a flange disposed at an angle above an exit of the exhaust channel, the flange configured to divert the air exiting upward from the exhaust channel in a direction under the portion of the cooking grate and toward a front of the appliance.

16. The home cooking appliance of claim 1 , wherein the flue gas air diverter includes a plate disposed at an angle above an exit of the exhaust channel, the plate configured to divert the air exiting upward from the exhaust channel in a direction under the portion of the cooking grate and toward a front of the appliance.

17. A home cooking appliance comprising:
a housing having a cooktop surface on a top of the housing;
a burner on the cooktop surface;
a cooking grate disposed above the burner;
a cooking compartment in the housing;
an exhaust channel that exhausts air from the cooking compartment;
a rear vent trim at a rear side of the top of the housing, the rear vent trim having at least one opening formed in a front surface of the rear vent trim, the at least one opening in communication with the exhaust channel; and
a flue gas air diverter capable of diverting the air exiting from the exhaust channel through the at least one opening and under a portion of the cooking grate,
wherein the flue gas air diverter is on a plate portion that is disposed between an exterior rear wall of the housing and a front wall of the exhaust channel and that forms an air gap between the plate portion and the exterior rear wall of the housing,
wherein the plate portion includes:
a first flange on an upstream side of the plate portion with respect to a flow of the air through the exhaust channel; and
a second flange on a downstream side of the plate portion with respect to the flow of the air through the exhaust channel,
wherein the plate portion, the first flange, and the second flange cooperate with the exterior rear wall to form the air gap.

18. The home cooking appliance of claim 17 , further comprising:
a second exhaust channel that exhausts air from the cooking compartment,
wherein the rear vent trim has at least one additional opening formed in the front surface of the rear vent trim, the at least one additional opening in communication with the exhaust channel; and
a second flue gas air diverter capable of diverting the air exiting from the exhaust channel through the at least one additional opening and under a second portion of the cooking grate, wherein the exhaust channel is spaced from the second exhaust channel.

19. A home cooking appliance comprising:
a housing having a cooktop surface on a top of the housing;
a burner on the cooktop surface;
a cooking grate disposed above the burner;
a cooking compartment in the housing;
an exhaust channel that exhausts air from the cooking compartment; and
means for diverting the air exiting from the exhaust channel under a portion of the cooking grate,
wherein the means for diverting is on a plate portion that is disposed between an exterior rear wall of the housing and a front wall of the exhaust channel and that forms an air gap between the plate portion and the exterior rear wall of the housing,
wherein the plate portion includes:
a first flange on an upstream side of the plate portion with respect to a flow of the air through the exhaust channel; and
a second flan
