A cool air circulation apparatus in a refrigerator provides an upper curved lip extended from a front face of a lower shelf in a refrigerating chamber, by which cool air contacting with ambient air is discharged outside of the refrigerator and only the cool air adjacent to the refrigerating chamber flows into the refrigerating chamber. Accordingly, even though a door of the refrigerating chamber is open for a long time or is opened and closed frequently, ambient air does not enter into the refrigerating chamber and thus cooling efficiency of the refrigerator increases. As a result, a constant temperature in the refrigerating chamber is maintained at all times, thereby being capable of maintaining freshness of a stored foods for a long time.

[ What is claimed is:] [1.] A cool air circulation apparatus in a refrigerator comprising:a refrigerator having an access opening at a front portion, in which a plurality of shelves are transversely provided in stacking type;a cool air supply duct installed on an upper portion of the access opening and discharging the cool air from the upper portion of the access opening toward a lower portion of the access opening;a cross flow fan installed in an inlet part of the cool air supply duct and forcedly ventilating the cool air;a cool air collecting duct, one side of which is extended toward the cross flow fan and another side of which is communicated with a plurality of cool air collecting openings formed between the shelves; andan upper curved lip facing the cool air supply duct at a front face of the lowest shelf among the shelves, thereby guiding one portion of the cool air into the refrigerating chamber.
