상술한 바와 같은 냉기유로 구성에서 냉장실(R) 내부에 냉기의 유동경로를 살펴보면, 상기 제1냉기유입구(26)에 공급된 냉기는 냉장실 후측벽(21)면에 형성된 제1냉기토출공(32)을 통해 냉기의 일부가 냉장실(R) 후측으로 토출되면서, 제1냉기덕트(30)를 따라 냉장실 우측벽(23)으로 이동하며, 상기 우측벽(23)으로 이동된 냉기는 우측벽(23) 전단에 형성된 제2냉기토출공(34)을 통해 냉장실(R) 우측으로 토출된다. 또한, 상기 제2냉기유입구(28)에 공급된 냉기는 제2냉기덕트(40)를 따라 냉장실 좌측벽(22) 전단으로 이동하며, 상기 좌측벽(22)면 전단에 형성된 제3냉기토출공(42)을 통해 냉장실(R) 좌측으로 토출된다. 이와 같이 각각 냉장실(R) 후측, 좌측 그리고 우측으로 토출된 냉기는 냉장실(R) 내부를 냉각시키게 된다.Looking at the flow path of the cold air in the refrigerating chamber (R) in the configuration of the cold air flow path as described above, the cold air supplied to the first cold air inlet 26 is formed in the first cold air discharge hole 32 formed on the rear wall 21 side of the refrigerating chamber (32). A portion of the cold air is discharged to the rear side of the refrigerating chamber (R), and moves to the refrigerating chamber right wall 23 along the first cold duct 30, and the cold air moved to the right wall 23 is the right wall 23. ) Is discharged to the right side of the refrigerating chamber (R) through the second cold air discharge hole (34) formed at the front end. In addition, the cold air supplied to the second cold air inlet 28 moves to the front end of the left side wall 22 of the refrigerating chamber along the second cold air duct 40, and the third cold air discharge hole formed at the front end of the left side wall 22. It is discharged to the left side of the refrigerating chamber R through the 42. As described above, the cold air discharged to the rear side, the left side, and the right side of the refrigerating chamber R cools the inside of the refrigerating chamber R, respectively.

그러나 상술한 바와 같은 종래기술에 의한 냉장실 유로구조는 냉장실 후측벽면의 냉기유입구과 냉장실 좌측벽면의 제2냉기유입구에 다른 경로로 냉기 공급되어, 냉장실의 우측 및 좌측에 공급되는 냉기의 풍량이 동일하지 않게 된다. However, the refrigerating chamber flow path structure according to the related art as described above is supplied with cold air through different paths to the cold air inlet on the rear wall of the refrigerating compartment and the second cold air inlet on the left side of the refrigerating compartment, so that the air volume of the cold air supplied to the right and left sides of the refrigerating compartment is not the same. do.

즉, 상기 냉장실 우측으로는 증발기로부터 직선유로를 통해 이동하는 냉기가 공급되고, 상기 냉장실 좌측으로는 수직으로 꺽이는 유로를 통해 이동하는 냉기가 공급되므로, 냉장실의 좌측벽으로 공급되는 냉기는 상기 제1냉기유입구로 공급되는 냉기보다 유로저항을 크게 받게되어, 상기 냉장실의 좌우측의 냉장상태가 달라지게 되고, 이에 따라 냉장실의 냉장성능이 저하되는 문제점이 있다. That is, since the cold air moving through the straight passage from the evaporator is supplied to the right side of the refrigerating compartment, the cold air moving through the vertically curved passage is supplied to the left side of the refrigerating compartment, so the cold air supplied to the left wall of the refrigerating compartment is supplied to the first wall. There is a problem in that the flow resistance is greater than that of the cold air supplied to the cold air inlet, and thus the refrigerating state of the left and right sides of the refrigerating compartment is changed, and thus the refrigerating performance of the refrigerating compartment is degraded.

본 발명은 상기 문제점을 해결하기 위해 안출된 것으로 냉장실 냉기유로를 단순화하는 것을 목적으로 한다. An object of the present invention is to simplify the refrigerating chamber cold air flow path to solve the above problems.

It is configured to supply cold air to the refrigerating chamber through a plurality of cold air discharge holes.

상기 제1냉기덕트 및 제2냉기덕트는 서로 대칭되게 구성되는 것이 바람직하다. Preferably, the first cold air duct and the second cold air duct are configured to be symmetric with each other.

The structure for simultaneously connecting two cold air ducts to the cold air inlet formed in one side wall of the refrigerating chamber may be configured in various shapes.

본 발명에 따르면, 냉장실 일측벽에 냉기유입구를 형성하고, 상기 냉기유입구에 두 개의 냉기유로가 동시에 연결되어, 냉기유로의 구조가 동일하게 형성됨으로써 유로구조가 단순하게 되고, 냉장실의 각측에 토출되는 냉기의 풍량이 균일해진다. According to the present invention, a cold air inlet is formed on one side wall of the refrigerating chamber, and two cold air flow passages are simultaneously connected to the cold air inlet, so that the structure of the cold air flow passage is the same, thereby simplifying the flow path structure and being discharged to each side of the refrigerating compartment. The air volume of cold air becomes uniform.

따라서, 유로저항이 감소하게 되고, 냉장고의 냉장실 내부가 균일하게 냉각되어 냉장실의 냉각성능이 향상된다. Therefore, the flow path resistance is reduced, and the inside of the refrigerator compartment of the refrigerator is uniformly cooled to improve the cooling performance of the refrigerator compartment.
