Hereinafter, with reference to the accompanying Figures 2 to 5 will be described in detail a preferred embodiment of the present invention.

2 and 3, the cold air supply structure of the French refrigerator according to the present invention includes a refrigerator main body 100 in which an upper refrigerating compartment 110 and a lower freezing compartment 120 are partitioned by partition walls, and the refrigerating compartment. Refrigerator door 130 for opening and closing the 110 and the freezer compartment 120, the evaporator 200 is installed on the rear wall surface of the freezer compartment 120, and the cold air cooled by passing the evaporator 200 is blown The blower fan 300 and the cold air blown by the blower fan 300 are guided to the refrigerating chamber 110 and the ice maker 140 installed in the refrigerating chamber 110, respectively. The damper 410 is configured to include a cold air duct 400 is installed.

First, the cold air duct 400 is disposed on the rear wall surface of the freezing chamber 120 of the refrigerator main body 100 to guide the cold air generated from the evaporator 200 to the refrigerating chamber 110 and the ice maker 140, respectively. do.

Specifically, the cold air duct 400 is a hollow cylindrical structure extending to a predetermined length, consisting of two passages bifurcated at any point extending from the bottom toward the top, one of the two passages Is communicated with the refrigerating compartment and the other passage is configured to communicate with an ice maker installed in the refrigerating compartment.
