Abstract

A refrigerator includes a first compartment, a second compartment and a multi-functional compartment that is disposed between the first compartment and the second compartment and is adjustable between temperature modes selected from the group consisting of a fresh food temperature mode, a soft freeze mode, a freezer mode and a chiller temperature mode.

Claims

1. A refrigerator comprising:

a first compartment;

a second compartment; and

a multifunctional compartment disposed between the first compartment and the second compartment, the multifunctional compartment being adjustable between temperature modes selected from the group consisting of a fresh food temperature mode, a soft freeze mode, a freezer mode, and a chiller temperature mode.

2. The refrigerator of claim 1, further comprising a heater for adjusting temperature in the multifunctional compartment.

3. The refrigerator of claim 2, further comprising a mullion which separates the multifunctional compartment from one of the first compartment and the second compartment, the multifunctional compartment being disposed above the one of the first compartment and the second compartment, the heater being supported by the mullion.

4. The refrigerator of claim 2, further comprising a sub-compartment, an evaporator disposed in the sub-compartment, a fan for distributing cooling air from the sub-compartment to the multifunctional compartment, a temperature sensor disposed in the multifunctional compartment for generating a temperature signal representing the temperature within the multifunctional compartment, and a controller operatively connected to the temperature sensor and the heater, the controller being configured to energize the heater after the temperature signal reaches a threshold.

5. The refrigerator of claim 4, further comprising a damper for selectively controlling an amount of the cooling air flowing into the multifunctional compartment from the sub-compartment.

6. A refrigerator comprising:

a fresh food compartment;

a freezer compartment; and

a multifunctional compartment disposed between the fresh food compartment and the freezer compartment, the multifunctional compartment being adjustable between temperature modes selected from the group consisting of a fresh food temperature mode, a soft freeze mode, a freezer mode, and a chiller compartment temperature mode.

7. The refrigerator of claim 6, further comprising a heater for adjusting temperature in the multifunctional compartment.

8. The refrigerator of claim 7, further comprising a mullion which separates the multifunctional compartment from one of the fresh food compartment and the freezer compartment, the multifunctional compartment being disposed above the one of the fresh food compartment and the freezer compartment, the heater being disposed in the multifunctional compartment and supported by the mullion.

9. The refrigerator of claim 8, wherein the mullion has a surface facing an interior of the multifunctional compartment, the heater being placed on the surface.

10. The refrigerator of claim 7, further comprising a first sub-compartment, a first evaporator disposed in the first sub-compartment, a first fan for distributing cooling air from the first sub-compartment to the multifunctional compartment, a temperature sensor disposed in the multifunctional compartment for generating a temperature signal representing the temperature within the multifunctional compartment, and a controller operatively connected to the temperature sensor and the heater, the controller being configured to energize the heater after the temperature signal reaches a threshold.

11. The refrigerator of claim 10, wherein the first fan is configured to distribute cooling air from the first sub-compartment to each of the fresh food compartment and the freezer compartment as well.

12. The refrigerator of claim 11, further comprising a conduit extending from the first sub-compartment to an upper location in the fresh food compartment, the first fan distributing cooling air from the first sub-compartment to the fresh food compartment through the conduit.

13. The refrigerator of claim 12, further comprising a first damper for selectively controlling an amount of cooling air flowing from the first sub-compartment to the conduit, and a second damper for selectively controlling an amount of cooling air flowing from the first sub-compartment to the multifunctional compartment.

14. The refrigerator of claim 12, further comprising a first damper for selectively controlling an amount of cooling air flowing from the first sub-compartment to the conduit, the mullion having an opening and a second fan for distributing cooling air from the one of the fresh food compartment and the freezer compartment to the multifunctional compartment.

15. The refrigerator of claim 10, further comprising a second sub-compartment, a second evaporator disposed in the second sub-compartment, and a second fan for distributing cooling air from the second sub-compartment to the freezer compartment.

16. The refrigerator of claim 15, wherein the first fan is configured to distribute cooling air from the first sub-compartment to the fresh food compartment as well.

17. The refrigerator of claim 16, further comprising a conduit extending from the first sub-compartment to an upper location in the fresh food compartment, the first fan being configured to distribute cooling air from the first sub-compartment to the fresh food compartment through the conduit.

18. The refrigerator of claim 17, further comprising a first damper for selectively controlling an amount of cooling air flowing from the first sub-compartment to the conduit, and a second damper for selectively controlling an amount of cooling air flowing from the first sub-compartment to the multifunctional compartment.

19. The refrigerator of claim 15, further comprising a conduit extending from the first sub-compartment to the multifunctional compartment, a first damper for selectively controlling an amount of cooling air flowing from the first sub-compartment to the conduit, and a second damper for selectively controlling an amount of cooling air flowing from the second sub-compartment to the freezer compartment.

20. The refrigerator of claim 7, further comprising a first sub-compartment, a second sub-compartment, a third sub-compartment, a first evaporator, a second evaporator and a third evaporator which are disposed in the first sub-compartment, the second sub-compartment and third sub-compartments, respectively, and a first fan, a second fan and a third fan for distributing cooling air from the first sub-compartment, the second sub-compartment and the third sub-compartment to the fresh food compartment, the multifunctional compartment, and the freezer, respectively.

21. A refrigerator comprising:

a fresh food compartment;

a freezer compartment disposed below the fresh food compartment;

a multifunctional compartment disposed between the fresh food compartment and the freezer compartment;

a heater disposed in the multifunctional compartment for increasing temperature in the multifunctional compartment;

a sub-compartment;

an evaporator disposed in the sub-compartment;

a fan for distributing cooling air from the sub-compartment to the multifunctional compartment;

a temperature sensor disposed in the multifunctional compartment for generating a temperature signal representing the temperature in the multifunctional compartment; and

a controller operatively connected to the temperature sensor and the heater, the controller being configured to energize at least one of the heater and the fan after the temperature signal reaches a threshold.
