Abstract

A refrigerator having a main body in which a freezer and a cooler are formed, including a freezer evaporator and a cooler evaporator connected with each other in series; a freezer fan and a cooler fan respectively ventilating cold air generated from the freezer evaporator and the cooler evaporator toward the freezer and the cooler; a cooler duct provided in front of the cooler evaporator to form a cold air pathway, and having an outlet provided on the cold air pathway and a ventilating hole formed to be penetrated in a lower side of the cooler evaporator to allow the cold air to be input/output; where the cold air generated at the cooler evaporator flows out to a lower area of the cooler through the ventilating hole when the cooler fan turns off, and the cold air of the lower area of the cooler flows into the cooler evaporator through the ventilating hole when the cooler fan turns on. Thus, the cold air flow of the refrigerator is increased which makes the cold air of the whole inside of the cooler flow smoothly and prevents a peripheral area of a cooler evaporator from overcooling or freezing.
