ABSTRACT:
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.
