ABSTRACT:
The present invention relates to an apparatus and method for controlling cold air circulation in a refrigerator. The present invention re-circulates cold air, which has been discharged into a refrigerating chamber (35), so that the interior of the refrigerating chamber (35) can be maintained at a substantially uniform temperature and relatively low temperature cold air is prevented from being delivered to an evaporator (39). Particularly, the present invention further facilitates the cold air circulation at a lower portion of the refrigerating chamber (35) so that the temperature of the entire refrigerating chamber (35) can be kept to be uniform and the temperature of a vegetable storage chamber (36) can be set at a desired temperature. To this end, an embodiment of the present invention includes a circulation duct (50) configured to suck the cold air around the vegetable storage chamber (36) and to discharge it to a relatively upper portion of the refrigerating chamber (35). An inlet (51) of the circulation duct (50) is installed in vicinity of a reward lower portion of the vegetable storage chamber (36), and an outlet of the circulation duct (50) is open to above a shelf (35′) corresponding to a top end of the vegetable storage chamber (36). Further, a circulation fan (54) is installed at the outlet (52).
