Refrigerator and method of manufacturing metal photocatalyst filter of the refrigerator

A refrigerator, comprising:

• a main body having a storage room formed therein;
• a cool air circulation path through which air within the storage room is circulated, the cool air circulation path having a cool air suction hole and a cool air outlet;
• a cool air circulation fan disposed in the cool air circulation path, and the cool air circulation fan to rotate about a rotating shaft that extends in front-rear direction and is disposed in a center of the cool air circulation path when viewed from a front side;
• a metal photocatalyst filter disposed in the cool air circulation path, the metal photocatalyst filter for filtering cool air to be conveyed to the storage room;
• and
• an ultraviolet ray (UV) LED module configured to radiate UV rays to the metal photocatalyst filter,
• wherein the metal photocatalyst filter and the UV LED module are sequentially disposed in an air flow direction of the cool air, the UV LED module is disposed to a rear of the metal photocatalyst filter, and
• the UV LED module includes a plurality of UV LEDs arranged across the cool air circulation path when viewed from a front side,
• wherein the UV LED module includes a frame disposed across the cool air circulation path when viewed from the front side, and the plurality of UV LEDs are arranged along the frame,
• wherein the plurality of UV LEDs comprising:
• a first LED disposed in the center of the cool air circulation path when viewed from a front side;
• and
• a plurality of pairs of second LEDs arranged symmetrically with respect to the first LED,
• wherein the frame has at least one pair of air outlets arranged symmetrically with respect to the first LED.
