Through the communication hole (32a) formed in the top plate 32 of 28 is introduced into the shelf member 28, respectively.
한편, 상기 선반부재(28)의 내측으로 유입된 냉기는 하부판(30)에 형성된 다수의 분사공(30a)을 통하여 냉장실(16)내로 분사됨으로써 냉각작용이 이루어지게 되는 것이다.On the other hand, the cold air introduced into the shelf member 28 is injected into the refrigerating chamber 16 through a plurality of injection holes (30a) formed in the lower plate 30 is to achieve a cooling action.
그리고, 상기 선반부재(28)의 내측에는 와류방지판(34)이 설치됨에 따라 연통공(32a)을 통하여 유입된 냉기가 와류를 형성시키지 않고 원활하게 분사공(30a)을 통하여 냉장실(16)내로 분사되어 진다.In addition, as the vortex preventing plate 34 is installed inside the shelf member 28, the cold air introduced through the communication hole 32a does not form a vortex, and the refrigerator compartment 16 is smoothly provided through the injection hole 30a. Sprayed into.
이때, 상기 냉장실(16)내에는 소정간격을 두고 삽입설치된 다수의 선반부재(28)에서 각각 냉기가 분사됨으로써 냉기의 순환작용이 원활하게 이루어질 뿐만 아니라 이로 인하여 냉각속도를 단축시킬수 있음은 물론 냉장실(16)내의 전체에 걸쳐서 온도분포가 균일하게 유지되어 저장물의 신선도를 현저히 향상시키게 되고, 저장물의 저장기간을 증대시킬 수 있게 된다.At this time, the cold air is sprayed from each of the plurality of shelf members 28 inserted into the refrigerator compartment 16 at predetermined intervals to smoothly circulate the cold air, thereby shortening the cooling rate, and of course, the refrigerator compartment ( 16) The temperature distribution is kept uniform throughout the whole, which significantly improves the freshness of the stored product and increases the storage period of the stored product.
또한, 상기 선반부재(28)상에 다량의 저장물이 놓여지더라도 선반부재(28)의 저면에 형성된 분사공(30a)내로 냉기가 분사됨으로써 냉기의 순환작용은 전혀 저하되지 않고 원활하게 이루어지게 된다.In addition, even if a large amount of storage is placed on the shelf member 28 by the cold air is injected into the injection hole (30a) formed on the bottom surface of the shelf member 28 so that the circulation action of the cold air is smoothly reduced without any degradation. do.
상술한 바와같이 본 고안에 따른 냉장고의 냉기공급장치에 의하면, 증발기에서 공급되는 냉기가 냉장실내에 각각 설치된 선반을 통하여 균일하게 분사됨으로써, 냉기의 원활한 순환작용으로 인하여 고내의 온도분포가 균일하게 유지될 뿐만 아니라 저장물의 신선도를 현저히 향상시킬 수 있음은 물론 저장물의 저장기간을 증대시킬 수 있는 등의 여러가지 이점을 갖는다.As described above, according to the cold air supply apparatus of the refrigerator according to the present invention, since the cold air supplied from the evaporator is uniformly sprayed through the shelves installed in the refrigerating chamber, the temperature distribution in the refrigerator can be maintained uniformly due to the smooth circulation of the cold air. In addition, the freshness of the storage can be significantly improved, as well as the storage period of the storage can be increased.
