And the cold air circulated in the freezing chamber 110 are guided to the evaporator 150 through the return flow path of the partition wall 210. .
그리고 냉장실(120)에서의 냉기의 순환은 회전날개(220)의 구동으로 냉동덕트(170)의 냉기를 냉장덕트(180)로 안내하게 된다.In addition, circulation of the cold air in the refrigerating chamber 120 guides the cold air of the freezing duct 170 to the refrigerating duct 180 by driving the rotary vane 220.
이때 이 안내된 냉기는 안내덕트(300)를 통하여 냉장실(120) 내부의 양측벽으로 안내된 후 안내덕트(300)의 각각의 토출구(310a)(310b)(310c)(310d)를 통하여 냉기가 냉장실(120) 내부로 토출되게 된다.At this time, the guided cold air is guided to both side walls of the refrigerating chamber 120 through the guide duct 300, and then the cold air is discharged through the respective discharge ports 310a, 310b, 310c and 310d of the guide duct 300. It is discharged into the refrigerating chamber 120.
이때 토출되는 냉기는 각각의 제 1토출구(310a)는 냉기를 냉장실(120) 내부의 전방으로 냉장실도어(140)를 따라 냉기를 토출시키고, 제 2토출구(310b)는 냉기를 냉장실(120)의 우측벽의 전방으로 토출하여 이동시킨다.At this time, the discharged cold air discharges the cold air along the refrigerating chamber door 140 to each of the first discharge port 310a in front of the refrigerating chamber 120, and the second discharge port 310b of the cold discharge chamber 120 Discharge and move to the front of the right wall.
그리고 제 3토출구(310c)는 냉기를 냉장실(120)의 후벽을 따라 토출하여 이동하게 하고, 제 4토출구(310d)는 냉기를 냉장실(120)의 좌측벽의 후방으로 토출시키게 된다.The third discharge port 310c discharges and moves cold air along the rear wall of the refrigerating chamber 120, and the fourth discharge port 310d discharges cold air to the rear of the left wall of the refrigerating chamber 120.
따라서 이러한 각각의 토출구(310a)(310b)(310c)(310d)의 토출방향이 동일방향으로 꺾여있고, 또한 내벽에 의한 안내로 냉장실(120) 내부에서 냉기가 일방향으로 회전하게된다. 이러한 냉기의 회전순환으로 냉장실(120) 내부에서의 고른 냉기의 공급이 이루어지도록 한다.Therefore, the discharge direction of each of the discharge ports 310a, 310b, 310c, 310d is bent in the same direction, and the cold air rotates in one direction inside the refrigerating chamber 120 by the guide by the inner wall. The rotational circulation of the cold air is such that the even supply of cold air is made in the refrigerating chamber 120.
그리고 열교환한 냉기는 상승하여 상부 격벽(210)에 있는 복귀덕트(200)를 통하여 안내되어 증발기(150)로 복귀하여 다시 냉각되게 된다.The cold air that has exchanged heat rises to be guided through the return duct 200 in the upper partition 210 to be returned to the evaporator 150 to be cooled again.
이상과 같은 본 고안의 토출구의 구조는 전술한 실시예뿐만 아니라 냉장실에 별도의 증발기가 설치된 냉장고에서도 적용가능하며, 또한 대부분의 밀폐식 저장시스템에 적용 가능하다.The structure of the discharge port of the present invention as described above is applicable to the refrigerator as well as the above-described embodiment, a separate evaporator is installed in the refrigerating chamber, and is also applicable to most closed storage systems.
이상과 같은 본 고안에 따른 냉장고의 냉기토출덕트는 저장실 내부에서의 냉기가 나선방향으로 회전하도록 냉기의 흐름을 개선함으로써 저장실 내부의 고른 냉각과 이에 따른 음식물의 냉각효율을 향상시킬 수 있으며, 또한 도어 개방시 외부로 누출되는 냉기의 손실을 최소한으로 줄일 수 있는 효과가 있다.The cold air discharge duct of the refrigerator according to the present invention as described above improves the flow of cold air so that the cool air inside the storage compartment rotates in a spiral direction, thereby improving the cooling efficiency of the inside of the storage compartment and thus the cooling efficiency of food. When opening, it is effective to minimize the loss of cold air leaking to the outside.
