Abstract

An icemaking compartment is provided in the refrigerator compartment of a bottom mount refrigerator. An icemaker is within the icemaking compartment. A cold air duct supplies cold air from the freezer compartment to the icemaker. The cold air duct is formed in the rear wall of the refrigerator. A fan controls the flow of air through the cold air duct. A return air duct is provided to direct a portion of the air from the icemaker back to the freezer compartment. An air vent in the icemaker directs another portion of air into the refrigerator compartment.

Claims (41)

1. A bottom mount refrigerator, comprising:

a freezer compartment having a freezer door;

a fresh food compartment located over the freezer compartment and having a fresh food door with an ice dispenser;

an icemaking compartment located away from a mullion wall of the refrigerator having an air temperature 32° F. or less;

an icemaker in the icemaking compartment wherein ice is frozen in the ice maker through below freezing air;

a fan for moving air from the freezer compartment into the icemaking compartment;

a cold air duct extending between a source of below freezing air and the icemaking compartment to supply cold air to the icemaking compartment, wherein the cold air duct remains uninterrupted by opening of the fresh food door; and

a return air duct extending between the icemaking compartment and the source of below freezing air.

2. The bottom mount refrigerator of claim 1 wherein the icemaking compartment includes an ice storage area.

3. The bottom mount refrigerator of claim 2 wherein the icemaker includes an ice mold positioned so that ice from the ice mold can be discharged into the storage area and dispensed by the ice dispenser.

4. The bottom mount refrigerator of claim 1 wherein the icemaking compartment is within the fresh food compartment.

5. The bottom mount refrigerator of claim 1 further comprising an air outlet in the icemaking compartment to vent air from the icemaking compartment to the fresh food compartment.

6. The bottom mount refrigerator of claim 1 wherein the fan is located adjacent the icemaker.

7. The bottom mount refrigerator of claim 5 wherein the icemaking compartment is located in an upper corner of the fresh food compartment.

8. The bottom mount refrigerator of claim 6 further comprising an air outlet in the icemaking compartment to vent air to the fresh food compartment.

9. A refrigerator, comprising:

a freezer compartment having a freezer door;

a fresh food compartment having a pair of fresh food doors;

an insulated intermediate temperature compartment located behind one of the pair of fresh food doors and away from a mullion wall having an air temperature between 0-32° F.;

a cold air duct in a wall of the refrigerator extending between the a source of below freezing air and the intermediate compartment;

a fan for moving air through the cold air duct from the freezer compartment to the intermediate compartment; and

a return air duct spaced apart from the fresh food door and extending between the intermediate compartment and the freezer compartment, wherein the cold air duct remains uninterrupted by opening of the fresh food door.

10. The refrigerator of claim 9 further comprising an icemaker in the intermediate compartment wherein ice is formed in the icemaker through below freezing air.

11. The refrigerator of claim 10 further comprising an ice dispenser in a fresh food door positioned so that ice from the intermediate temperature compartment can be dispensed.

12. The refrigerator of claim 11 further comprising an ice storage area within a fresh food door in engagement with the intermediate compartment when the fresh food door is closed.

13. The refrigerator of claim 9 wherein the intermediate compartment has an ice storage area.

14. A bottom mount refrigerator, comprising:

a freezer compartment;

a freezer compartment door providing access to the freezer compartment;

a fresh food compartment located over the freezer compartment;

a fresh food compartment door providing access to the fresh food compartment and having an ice dispenser;

an icemaking compartment spaced from a mullion wall separating the freezer compartment and fresh food compartment;

an icemaker with an ice mold in the icemaking compartment wherein ice is made in the ice mold through below freezing air;

a cold air duct extending between the freezer compartment and the icemaking compartment to supply cold air from a source of below freezing air to the icemaker, wherein the cold air duct remains uninterrupted by opening of the fresh food compartment door;

a fan for moving air from over the ice mold; and

a return air duct extending between the icemaker and the source of below freezing air.

15. The bottom mount refrigerator of claim 14 wherein the fan is located adjacent the icemaker.

16. The bottom mount refrigerator of claim 14 wherein the icemaking compartment is located in an upper corner of the fresh food compartment.

17. The bottom mount refrigerator of claim 14 further comprising an air outlet in the icemaking compartment to vent air to the fresh food compartment.

18. The bottom mount refrigerator of claim 14 wherein the icemaking compartment has a temperature maintained between 0-32° F.

19. The bottom mount refrigerator of claim 14 wherein the cold air duct is at least partially disposed within an insulated wall of the refrigerator.
