Abstract

A refrigerator includes a plurality of walls forming a refrigeration compartment, an evaporator is positioned proximate at least one of the walls, a thermal insulator is positioned proximate the evaporator, and an airflow duct is positioned proximate the thermal insulator such that the thermal insulator is between the evaporator and the airflow duct.

Claims (21)

1. A refrigerator comprising:

a plurality of walls forming a refrigeration compartment and a freezer compartment;

an evaporator positioned proximate at least one of said walls;

a thermal insulator positioned proximate said evaporator;

a cover positioned a distance from said thermal insulator, said cover comprising an inner surface and an outer surface, said outer surface exposed to the refrigeration compartment, said inner surface facing said thermal insulator; and

an airflow duct defined between said inner surface of said cover and said thermal insulator, said airflow duct configured to channel airflow from the refrigeration compartment along said thermal insulator, said thermal insulator positioned between said evaporator and said airflow duct, wherein a combined thickness of said airflow duct and said thermal insulator is less than one inch.

2. A refrigerator according to claim 1 , wherein said evaporator is positioned proximate one of said walls and extends to said thermal insulator.

3. A refrigerator according to claim 1 , wherein said thermal insulator linearly extends between two vertical sides.

4. A refrigerator according to claim 1 , wherein said thermal insulator includes a planar side comprising a surface of said airflow duct and an opposite side adjoining said evaporator.

5. A refrigerator according to claim 1 , wherein said cover comprises a plurality of openings.

6. A refrigerator according to claim 1 , wherein said cover comprises a plurality of louvers.

7. A refrigerator according to claim 1 , wherein the airflow channeled along said thermal insulator is configured to increase a temperature of said thermal insulator.

8. A method for assembling a refrigerator, said method comprising:

providing a plurality of walls forming a refrigeration compartment and a freezer compartment;

positioning an evaporator proximate at least one of the walls;

positioning a thermal insulator proximate the evaporator; and

positioning a cover a distance from the thermal insulator, the cover comprising an inner surface and an outer surface, the outer surface exposed to the refrigeration compartment, the inner surface facing the thermal insulator, such that an airflow duct is defined between the cover and the thermal insulator, wherein airflow from the refrigeration compartment is configured to be channeled through the airflow duct along the thermal insulator, and wherein the thermal insulator is positioned between the airflow duct and the evaporator such that a combined thickness of the airflow duct and the thermal insulator is less than one inch.

9. A method according to claim 8 , wherein positioning an evaporator proximate at least one of the walls comprises positioning the evaporator proximate one of the walls and extending the evaporator to the insulator.

10. A method according to claim 8 , wherein positioning a thermal insulator proximate the evaporator comprises positioning the thermal insulator such that the thermal insulator linearly extends between two vertical sides.

11. A method according to claim 8 , wherein positioning a thermal insulator proximate the evaporator comprises positioning the thermal insulator such that a planar side of the thermal insulator comprises a surface of the airflow duct and an opposite side of the thermal insulator adjoins the evaporator.

12. A method according to claim 8 , wherein the airflow channeled along the thermal insulator is configured to increase facilitates increasing a temperature of the thermal insulator.
