Refrigerator

A refrigerator, comprising:

• an ultraviolet discharging lamp, for irradiating ultraviolet rays to an air duct inside the refrigerator, and irradiating a visible light to a cold storage compartment of the refrigerator;
• a light catalyst filter, installed in the air duct and activated by the ultraviolet rays;
• a fan for forming an air curtain when a door of the cold storage compartment of the refrigerator is opened;
• and
• a controlling device for lighting the ultraviolet discharging lamp when the door of the cold storage compartment of the refrigerator is opened.
