Appliance exhaust duct cover and method of assembling same

1. A method for assembling an appliance vent duct cover assembly, said method comprising:

providing a first cover portion having a first cross-sectional profile;

slidably coupling a second cover portion defining a plurality of openings to the first cover portion forming a vent duct cover defining an upstream end and a downstream end, the second cover portion having a second cross-sectional profile substantially similar to the first cross-sectional profile; and

selectively positioning a first end portion of the second cover portion within the first cover portion such that a first end portion of the first cover portion substantially covers the second cover portion openings in a first orientation facilitating venting gases through the downstream end, and an opposing second end portion of the second cover portion within the first cover portion such that the second cover portion openings are substantially unobstructed in a second orientation facilitating venting the gases through the plurality of openings.

2. A method in accordance with claim 1 wherein the first cross-sectional profile defines a first cross-sectional area and the second cross-sectional profile defines a second cross-sectional area that is smaller than the first cross-sectional area, said slidably coupling the second cover portion to the first cover portion further comprises positioning the second cover portion at least partially within the first cover portion.

3. A method in accordance with claim 1 wherein slidably coupling the second cover portion and the first cover portion further comprises slidably coupling the first cover portion and the second cover portion such that a lower surface of the first cover portion contacts an upper surface of a range hood and such that an upper surface or the second cover portion contacts a ceiling.

4. A method in accordance with claim 1 further comprising securing the first cover portion to the second cover portion using at least one fastener.

5. An appliance vent duct cover assembly comprising:

a first cover portion having a first cross-sectional profile; and

a second cover portion comprising a plurality of openings extending therethrough, said second cover portion slidably coupled to said first cover portion and having a second cross-sectional profile substantially similar to the first cross-sectional profile, a first end portion of said second cover portion is selectively positionable within said first cover portion to enable said plurality of openings to be substantially covered by said first cover portion in a first orientation facilitating venting gases through said second cover portion, and an opposing second end portion of the second cover portion is selectively positionable within said first cover portion such that said plurality of openings are substantially unobstructed in a second orientation facilitating venting gases through said plurality of openings.

6. An appliance vent duct cover assembly in accordance with claim 5 wherein said first cross-sectional profile defines a first cross-sectional area and said second cross-sectional profile defines a second cross-sectional area that is smaller than said first cross-sectional area.

7. An appliance vent duct cover assembly in accordance with claim 5 wherein at least a portion of said second cover portion is positioned at least partially within said first cover portion.

8. An appliance vent duct cover assembly in accordance with claim 5 wherein said first cover portion comprises a stainless steel material, said second cover portion comprises a stainless steel material.

9. An appliance vent duct cover assembly in accordance with claim 5 wherein said first cover portion comprises a first coupling apparatus, said second cover portion comprises a second coupling apparatus configured to couple to said first coupling apparatus.

10. An appliance vent duct cover assembly in accordance with claim 5 wherein said first cover portion is configured to contact a range hood and said second cover portion is configured to contact a ceiling.

11. An appliance vent duct cover assembly in accordance with claim 5 wherein said second cover portion comprises a plurality of openings in flow communication with a vent duct.

12. An appliance vent duct cover assembly in accordance with claim 5 wherein said second cover portion comprises a first end and a second end, said first end positioned at least partially within said first cover portion to enable said openings to be substantially covered by said first cover portion, or said second end positioned at least partially within said first cover portion to enable said openings to be in flow communication with a vent duct.

13. An appliance range hood comprising:

a vent duct coupled to said range hood and extending from an upper surface of said range hood at least partially towards a ceiling; and

a vent duct cover assembly at least partially circumscribing said vent duct, said vent duct cover assembly comprising:

a first cover portion; and

a second cover portion comprising a plurality of openings defined therethrough, said second cover portion slidably coupled to said first cover portion defining a downstream end and an upstream end, said second cover portion is selectively positionable with respect to said first cover portion such that said plurality of openings are substantially covered by said first cover portion in a first orientation facilitating venting gases through said downstream end, and said plurality of openings are substantially unobstructed in a second orientation facilitating venting gases through said plurality of openings.

14. An appliance range hood in accordance with claim 13 wherein said first cover portion comprises an outer surface having a first cross-sectional area, said second cover portion comprises an outer surface having a second cross-sectional area that is smaller than said first cross-sectional area.

15. An appliance range hood in accordance with claim 13 wherein at least a portion of said second cover portion is positioned at least partially within said first cover portion.

16. An appliance range hood in accordance with claim 13 wherein said first cover portion comprises a stainless steel material, said second cover portion comprises a stainless steel material.

17. An appliance range hood in accordance with claim 13 wherein said first cover portion comprises a first coupling apparatus, said second cover portion comprises a second coupling apparatus configured to couple to said first coupling apparatus.

18. An appliance range hood in accordance with claim 13 wherein said first cover portion extends at least partially over an outer surface of said second cover portion such that said second cover portion is selectively extended from said first portion to fit between said range hood and a ceiling.

19. An appliance range hood in accordance with claim 13 wherein said second cover portion comprises a plurality of openings coupled in flow communication with a vent duct.

20. An appliance range hood in accordance with claim 13 wherein said second cover portion comprises a first end and a second end, said first end positioned at least partially within said first cover portion to enable said plurality of openings to be substantially covered by said first cover portion, said second cover portion positioned at least partially within said first cover portion to enable said plurality of openings to be coupled in flow communication with a vent duct.
