Claim:
A cooling air supply apparatus of a refrigerator compartment and a freezing compartment that stores food at low temperature, a barrier that partitions the refrigerating compartment and the freezing compartment from each other, and a receiving box mounted in the refrigerating compartment that receives food, wherein the cooling air supply apparatus comprises: a communication port formed through the barrier that guides cooling air from the freezing compartment into the refrigerating compartment; a hollow box-shaped cover mounted at a top part of the receiving box, wherein the cover includes: an upper plate, comprising: a top wall; and a sidewall that extends all the way along and downward from an outer peripheral edge of the top wall, including: a front wall that extends downward from a front edge of the top wall; a rear wall that extends downward from a rear edge of the top wall; left and right lateral side walls that extend downward from left and right side edges, respectively, of the top wall; and a rim that extends inward from a lower peripheral edge of the sidewall so as to form a coupling surface; an introduction port formed in the upper plate, at a peripheral portion thereof, so as to communicate with the communication port; a lower plate coupled to a lower portion of the upper plate along corresponding edge portions thereof so as to define a hollow interior space therebetween, wherein the lower plate is coupled to the rim of the upper plate; and at least one cooling air supplying hole formed in the lower plate so as to communicate with an interior of the receiving box; and a duct that extends between the communication port and the introduction port such that the communication port and the introduction port communicate with each other, wherein the duct provides cooling air from the freezing compartment into the interior of the cover, and wherein substantially all of the cooling air provided through the duct is guided into the cover and into the interior of the receiving box through the at least one cooling air supplying hole.
