상기와 같이 구성되는 본 발명의 덕트선반에 의한 냉기의 순환과정을 설명하기 위해 제3도 내지 제4도를 다시 인용한다.In order to explain the circulation process of the cold air by the duct shelf of this invention comprised as mentioned above, the 3rd-4th drawing is quoted again.

상기 냉각실(미도시) 토출되는 찬냉기의 일부가 쉬라우드와 그릴팬(미도시)에 의해 낙하되어 냉장실 덕트(10)로 유입되고, 그 유입된 냉기는 냉장실 덕트(10)의 중앙측에 구비된 냉장실 토출덕트(11)를 통해 덕트선반(20)의 각 토출유로(21)로 안내되고, 그 덕트선반 토출유로(21)로 안내된 찬냉기는 그 토출유로(21)의 하측면에 형성된 각덕트선반 토출공(21a)를 통해 칸칸마다에 분산되며, 그 분산되는 찬냉기는 각 칸의 수납물과 열교환 된 후에 더워져 다시 각각의 덕트선반 흡입공(22a)(22a')로 흡입되어 덕트선반 흡입유로(22)(22')를 통해 냉장실 흡입덕트(12)(12')로 유입된다. 그 유입된 더운 냉기는 상기 냉장실 흡입덕트(12)(12')를 따라 흡상되어 다시 냉각실(미도시)에서 재냉각되는 것이다.A portion of the cold air discharged from the cooling chamber (not shown) is dropped by the shroud and the grill pan (not shown) to flow into the refrigerator compartment duct 10, and the introduced cold air is located at the center side of the refrigerator compartment duct 10.
