Field of the Invention The present invention relates to a cabinet forming a cooling chamber, and at least one cold air discharge port provided in a side wall of the cooling chamber to form a cool air passage and open toward the inside of the cooling chamber. More particularly, the present invention relates to a refrigerator having a cool air distribution device for uniformly distributing cool air into a cooling room.

される。2. Description of the Related Art In general, a refrigerator has a cabinet forming a pair of cooling chambers, ie, a freezer compartment and a refrigerator compartment, separated by an intermediate partition, a freezer compartment door and a refrigerator compartment door for opening and closing each cooling compartment, and a freezer compartment and a refrigerator. A refrigeration system including a compressor, a condenser, and an evaporator for supplying cool air to the chamber is provided. Cool air generated from the evaporator flows along a supply duct formed in a rear wall of each cooling chamber, and is supplied to each cooling chamber through a cool air discharge port toward the cooling chamber by a blower fan.

を図っている。However, in such a conventional refrigerator, there is a region where the cool air discharged through the cool air discharge port is provided intensively and a region where the cool air is supplied in a relatively small amount. There is a problem that uniform cooling is not performed. Then, a so-called three-dimensional cooling type refrigerator that has solved such problems has been proposed.
In the three-dimensional cooling refrigerator, a large number of cooling air discharge ports are provided on the rear wall surface and both side wall surfaces of the cooling chamber, respectively, so as to uniformly supply the cool air.

趨勢と関連してとても大切な問題点となってきた。However, even in such a refrigerator of the three-dimensional cooling type, since cool air is discharged in a certain direction through a cool air discharge port, there may be a dead zone in an angle region where the supply of cool air is insufficient. In particular, since the supply duct must be provided not only on the rear wall but also on the side wall of the cooling chamber, there is a problem that the accommodation space for food and drink is reduced, and the number of parts and the number of processes increase, thereby increasing the manufacturing cost. . The uniform distribution of cool air in the cooling room has become a very important problem in connection with the trend of refrigerators becoming larger.
