Refrigeration with air purification

A refrigerator comprising:

• a cabinet that includes an interior area;
• an evaporator that is provided in the interior area and configured to cool a first portion of air in the interior area;
• a grill pan that faces the interior area, the grill pan including a first discharge port and a second discharge port;
• a purification device that is coupled to an upper portion of the grill pan and that is configured to (i) draw a second portion of the air from the interior area and (ii) purify the second portion of the air, the purification device including a suction port into which the second portion of the air is introduced and a purification fan;
• a cold air duct that is disposed rearward of the grill pan and that is configured to guide the first portion of the air that has been cooled by the evaporator through a first passage;
• a purification duct that is spaced apart from the cold air duct, the purification duct including (i) a duct hole communicated with the suction port and (ii) a second passage through which the second portion of the air passing through the purification fan flows to the interior area;
• and
• a cold air fan that is configured to provide the first portion of the air from the evaporator to the first passage,
• wherein the first passage is isolated from the second passage,
• wherein the cold air fan is located in a lower side of the grill pan such that the first portion of the air passing through the cold air fan flows upwardly and is discharged toward the interior area through the first discharge port, and
• wherein the suction port of the purification device is located above the second discharge port such that the second portion of the air passing through the purification fan flows downwardly and is discharged toward the interior area through the second discharge port.
