Abstract

A refrigerator is disclosed. The refrigerator is able to store food at a low temperature and to effectively remove bacteria of the food stored in a storage room, to maintain the storage room clean.

First claim

What is claimed is:

1. A refrigerator, comprising:
a cabinet having at least one storage compartment;
at least one door that selectively opens and closes the cabinet and the at least one storage compartment;
plurality of shelves vertically disposed within the at least one storage compartment, that partitions the at bast one storage compartment into a plurality of storage sections;
a first duct mounted on a rear wall of the at least one storage compartment to supply cold air, the first duct extending between the plurality of storage sections and having plurality of cold air supply holes that supplies the cold air into the plurality of storage sections;
a filter module that filters air inside of the at least one storage compartment, the filter module comprising:
a filter mounted on the rear wall of the at least one storage compartment to filter air within the at least one storage compartment;
a second duct connected to toe niter, wherein the second duct supplies air filtered by the filter to the at least one storage compartment, extends between the plurality of storage sections, and includes a plurality of passing holes through which the filtered air is supplied into the plurality of storage sections; and
a fan that allows air within the storage compartment to flow into the second duct through the filter,
wherein air flow through the second duct does not cross with air flow through the first duct.

2. The refrigerator of claim 1 , wherein the filter module further comprises a housing, and wherein the filter and the fan are disposed within the housing.

3. The refrigerator of claim 2 , wherein the filter is removably disposed within the housing.

4. The refrigerator of claim 1 , wherein the first and second ducts are integrated as a multi-duct adjacent the at least one storage compartment.

5. The refrigerator of claim 1 , wherein the at least one first duct comprises at least two first ducts, and the second duct is positioned between the at least two first ducts.

6. The refrigerator of claim 1 , wherein the filter comprises at least one sterilization device.

7. The refrigerator of claim 6 , wherein the at least one sterilization device comprises at least one sterilization filter.

8. The refrigerator of claim 7 , wherein the at least one sterilization filter is coated with a leuconostoc enzyme.

9. The refrigerator of claim 7 , wherein the filter further comprises an anti-allergen filter.

10. The refrigerator of claim 9 , wherein the filter farther comprises a deodorization filter.

11. The refrigerator of claim 1 , wherein the module further comprises a housing, and wherein the filter and the fan are disposed within the housing.

12. The refrigerator of claim 11 , wherein the filter is removably disposed within the housing.

13. The refrigerator of claim 6 , wherein the at least one sterilization device comprises a UV light source.

14. The refrigerator of claim 13 , wherein the UV light source is disposed within the second duct.

15. The refrigerator of claim 13 , wherein the UV light source comprises a UV LED.

16. The refrigerator of claim 13 , wherein the filter further comprises a photocatalyst filter.

17. The refrigerator of claim 16 , wherein the photocatalyst filter is coated with titanium.

18. The refrigerator of claim 6 , wherein the at least one sterilization device comprises a UV LED.

19. The refrigerator of claim 18 , wherein the LED is disposed within the second duct.

20. The refrigerator of claim 1 , further comprising:
a plurality of shelves disposed within the at least one storage compartment.

21. The refrigerator of claim 1 , further comprising a controller that selectively drives the fan.

22. The refrigerator of claim 21 , further comprising an input that receives input of an operational mode of the filter module.

23. The refrigerator of claim 21 , further comprising a display that displays the operational mode of the filter module.

24. The refrigerator of claim 1 , wherein the second duct extends vertically in the cabinet and the plurality of passing holes extends vertically along the second duct.

25. The refrigerator of claim 24 , wherein the filter module further comprises a housing, and wherein the filter and the fan are, disposed within the housing.

26. The refrigerator of claim 25 , wherein the filter is removably disposed within the housing.

27. The refrigerator of claim 24 , wherein the filter comprises at least one sterilization filter.

28. The refrigerator of claim 24 , wherein the at least one sterilization filter is coated with a leuconostoc enzyme.

29. The refrigerator of claim 28 , wherein the filter further comprises an anti-allergen filter.

30. The refrigerator of claim 29 , wherein the filter further comprises a deodorization filter.

31. The refrigerator of claim 24 , wherein the filter comprises a UV light source.

32. The refrigerator of claim 31 , wherein the light source comprises a UV LED.

33. The refrigerator of claim 31 , wherein the filter further comprises a photocatalyst filter.

34. The refrigerator of claim 24 , further comprising:
a plurality of shelves disposed within the at least one storage compartment.

35. The refrigerator of claim 24 , further comprising a controller that selectively drives the fan.

36. The refrigerator of claim 35 , further comprising an input that receives input of an operational mode of the filter module.

37. The refrigerator of claim 36 , farther comprising a display that displays the operational mode of the filter module.

38. The refrigerator of claim 1 , further comprising:
a sensor that senses a status of stored goods within the at least one storage compartment; and
a controller that controls an operation of the filter module based on a detection result of the sensor.

39. The refrigerator of claim 38 , wherein the filter module comprises:
at least one steam generator.

40. The refrigerator of claim 39 , wherein the sensor comprises at least one of:
a bio-sensor that detects a specific bacteria contaminant;
a gas sensor that detects an offensive smell;
a weight sensor that measures a weight of stored goods; or
a temperature sensor that senses a temperature of the at least one storage compartment.

41. The refrigerator of claim 40 , wherein the sensor comprises a bio-sensor.

42. The refrigerator of claim 41 , further comprising:
a microbial response viewer (MRV) system that manages microbes for each of a predetermined kind of stored goods.

43. The refrigerator of claim 42 , wherein the controller controls a spraying time and a spraying temperature of the at least one steam generator based on a kind and amount of bacteria detected by the bio-sensor and MRV system.
