Abstract

A home cooking appliance includes a rear vent trim at a rear side of the top of the housing that is configured to guide flue gases exiting from an exhaust channel of a cooking compartment in an upward direction out of the housing. The rear vent trim includes a body, a back panel closing a rear side of the body, and a heat shield disposed between the back panel and the flue gases flowing in the rear vent trim. The heat shield is spaced from the back panel and forms an air gap between the back panel and the heat shield.

First claim

What is claimed is:

1. A home cooking appliance comprising:
a housing having a cooktop on a top of the housing and a cooking compartment in the housing;
an exhaust channel that exhausts flue gases from the cooking compartment; and
a rear vent trim at a rear side of the top of the housing and configured to guide the flue gases exiting from the exhaust channel in an upward direction out of the housing,
the rear vent trim including:
a body having a front surface, a first side surface, a second side surface, and an upper surface, the upper surface including at least one opening in fluid communication with the exhaust channel, the at least one opening configured to permit the flue gases exiting from the exhaust channel to flow in the upward direction out of the rear vent trim;
a back panel closing a rear side of the body of the vent trim, the back panel forming a back of the appliance configured to be adjacent to a back wall of a kitchen; and
a heat shield disposed adjacent to the back panel, and between the back panel and the flue gases flowing in the rear vent trim, wherein the heat shield is spaced from the back panel and forms an air gap between the back panel and the heat shield,
wherein the back panel or the heat shield has a plurality of embosses and the heat shield is supported on the back panel by the plurality of embosses such that the heat shield is spaced from the back panel.

2. The home cooking appliance of claim 1 , wherein the heat shield includes:
a front surface configured to guide the flue gases in the upward direction through the body; and
a rear surface spaced from a forward facing surface of the back panel.

3. The home cooking appliance of claim 1 , wherein side edges of the heat shield are spaced from the first side surface and the second side surface, respectively.

4. The home cooking appliance of claim 1 , wherein the heat shield includes an angled flange configured to induce turbulent flow in the flue gases exiting in the upward direction from the at least one opening of the rear vent trim.

5. The home cooking appliance of claim 4 , wherein the angled flange extends from an upper edge of the heat shield.

6. The home cooking appliance of claim 5 , wherein the angled flange extends along an entire length of the upper edge of the heat shield.

7. The home cooking appliance of claim 5 , wherein the angled flange extends along only a portion of a length of the upper edge of the heat shield.

8. The home cooking appliance of claim 7 , wherein the angled flange is centered along the length of the heat shield.

9. The home cooking appliance of claim 1 , wherein the rear vent trim includes a first side shield spaced from the first side surface of the body and a second side shield spaced from the second side surface of the body.

10. The home cooking appliance of claim 9 , wherein the first side shield includes an inward facing surface configured to guide the flue gases in the upward direction through the body and an outward facing surface facing the first side surface of the body and spaced from the first side surface of the body, and
wherein the second side shield includes an inward facing surface configured to guide the flue gases in the upward direction through the body and an outward facing surface facing the second side surface of the body and spaced from the second side surface of the body.

11. The home cooking appliance of claim 1 , wherein the back panel includes a stiffening rib extending along a portion of the back panel.

12. The home cooking appliance of claim 11 , wherein the stiffening rib is stamped into the back panel.

13. A home cooking appliance comprising:
a housing having a cooktop on a top of the housing and a cooking compartment in the housing;
an exhaust channel that exhausts flue gases from the cooking compartment; and
a rear vent trim at a rear side of the top of the housing and configured to guide the flue gases exiting from the exhaust channel in an upward direction out of the housing,
the rear vent trim including:
a body having a front surface, a first side surface, a second side surface, and an upper surface, the upper surface including at least one opening in fluid communication with the exhaust channel, the at least one opening configured to permit the flue gases exiting from the exhaust channel to flow in the upward direction out of the rear vent trim;
a back panel closing a rear side of the body; and
a heat shield disposed between the back panel and the flue gases flowing in the rear vent trim, wherein the heat shield is spaced from the back panel and forms an air gap between the back panel and the heat shield,

wherein the rear vent trim includes at least one standoff bracket on a rearward facing surface of the back panel.

14. The home cooking appliance of claim 1 , wherein the upper surface of the body of the rear vent trim is disposed at an elevated position with respect to the rear side of the top of the housing.

15. The home cooking appliance of claim 1 , wherein the air gap between the back panel and the heat shield is configured to guide cooling air in the upward direction between the back panel and the heat shield.

16. A home cooking appliance comprising:
a housing having a cooktop on a top of the housing and a cooking compartment in the housing;
an exhaust channel that exhausts flue gases from the cooking compartment; and
a rear vent trim at a rear side of the top of the housing and configured to guide the flue gases exiting from the exhaust channel in an upward direction out of the housing,
the rear vent trim including:
a body having a front surface, a first side surface, a second side surface, and an upper surface, the upper surface including at least one opening in fluid communication with the exhaust channel, the at least one opening configured to permit the flue gases exiting from the exhaust channel to flow in the upward direction out of the rear vent trim;
a back panel closing a rear side of the body of the vent trim, the back panel forming a back of the appliance configured to be adjacent to a back wall of a kitchen; and
a heat shield disposed adjacent to the back panel, and between the back panel and the flue gases flowing in the rear vent trim, wherein the heat shield is spaced from the back panel and forms an air gap between the back panel and the heat shield,
wherein the back panel includes a plurality of first embosses facing the heat shield and the heat shield includes a plurality of second embosses facing the back panel, and
wherein the plurality of first embosses are secured to the plurality of second embosses to support the heat shield on the back panel in a spaced manner from the back panel.

17. The home cooking appliance of claim 16 , wherein the rear vent trim includes a plurality of fasteners securing the plurality of first embosses to the plurality of second embosses.
