Description
본 고안은 냉각 덕트가 구비된 냉장고 선반에 관한 것으로, 특히 냉동실의 냉기를 냉장실 측으로 유입시키기 위해 냉장고 캐비넷 내측에 형성된 주냉각 덕트와 연결되어 냉기를 냉장실 고내 전체에 토출하는 구성을 갖는 냉각 덕트가 구비된 냉장고 선반에 관한 것이다.The present invention relates to a refrigerator shelf provided with a cooling duct, and in particular, the cooling duct is connected to the main cooling duct formed inside the refrigerator cabinet to introduce the cold air of the freezer compartment into the refrigerating compartment side to discharge the cold air to the entire inside of the refrigerating compartment. It is about a refrigerator shelf.
일반적으로 냉장고는 영하의 온도를 유지하는 냉동실과 영상의 온도로 유지되는 냉장실이 냉장고 캐비넷의 내측에 저장공간으로 제공되고, 상기 냉장실에는 복수개의 냉장고 선반이 장착되었다.In general, a refrigerator is provided with a freezer compartment that maintains a temperature below zero and a refrigerator compartment maintained at an image temperature as a storage space inside the refrigerator cabinet, and the refrigerator compartment is equipped with a plurality of refrigerator shelves.
이러한 냉장고 선반은 상면에 물건이 놓이게 되면 물품의 하중에 의해 변형되므로 강화 플라스틱으로 성형되거나 강화 유리판 제작되고, 이물질이 묻어 더럽혀질 경우 냉장실로부터 용이하게 분리 가능하도록 냉장실 내상벽에 슬라이드 가능하게 설치되었다.Since the refrigerator shelf is deformed by the load of the article when the article is placed on the upper surface, the refrigerator shelf is formed of reinforced plastic or made of tempered glass, and is slidably installed on the inner wall of the refrigerating compartment so that it can be easily separated from the refrigerating compartment when foreign matter gets dirty.
한편, 통상적인 냉장고는 냉각 성능을 고려하여 1개의 냉각 시스템 즉, 냉동실측에 설치된 1개의 증발기에 의해 냉각되며, 상기 증발기는 냉장고 하단부에 설치된 압축기와 유체 소통 가능하게 연결되어 있고 상기 압축기로부터 압축된 냉매가 팽창 밸브를 통과하면서 저온 감압되어 전달됨으로써, 냉매가 증발기에서 냉동실 고내의 열을 흡수하면서 증발되어 냉동실을 저온 상태로 유지하였다. 이와 같은 과정을 통해 발생된 냉동실의 냉기는 냉장고 캐비넷 내측에 형성된 냉기 덕트를 통해 냉장실로 유입되어 냉장고 선반에 놓여진 물품을 냉각하는데 사용되어 왔다.On the other hand, the conventional refrigerator is cooled by one cooling system, that is, one evaporator installed on the freezer side in consideration of cooling performance, and the evaporator is connected in fluid communication with a compressor installed at the lower end of the refrigerator and compressed from the compressor. As the refrigerant passed through the expansion valve at low temperature and reduced pressure, the refrigerant was evaporated while absorbing heat in the freezer compartment in the evaporator to keep the freezer at a low temperature. The cold air of the freezer compartment generated through such a process has been used to cool the goods placed on the refrigerator shelves through the cold air duct formed inside the refrigerator cabinet.
종래의 냉장고가 개략적으로 도시된 도 1을 참고하면, 냉장고는 냉장고 캐비넷(5)의 내상 벽(7)으로 둘러싸여 형성된 냉장실(2)과 냉동실을 구비한다.Referring to FIG. 1, in which a conventional refrigerator is schematically illustrated, the refrigerator includes a refrigerating chamber 2 and a freezing chamber formed by an inner wall 7 of the refrigerator cabinet 5.
또한, 냉장고 선반(9)이 장착되어 전후 슬라이드되도록 냉장고의 고내측 내상 벽(7))에 돌출하여 가이드 부재(8)가 형성되고, 상기 가이드 부재의 홈(8a)에선반(9)의 양측단부가 끼워져 장착되었다. 더욱이, 냉장실에 보관된 물품이 저온으로 보관되도록 도 2에 도시된 바와 같이, 냉각 덕트(3)가 냉장고 캐비넷(5)의 내측 즉, 냉장실의 내상 벽(7)의 후측에 형성된다.In addition, a guide member 8 is formed by protruding from the inner inner inner wall 7 of the refrigerator so that the refrigerator shelf 9 is mounted and slides back and forth, and both sides of the shelf 9 are formed in the groove 8a of the guide member. The end was fitted and fitted. Moreover, as shown in FIG. 2, the cooling duct 3 is formed inside the refrigerator cabinet 5, that is, on the rear side of the inner wall 7 of the refrigerator compartment, so that the article stored in the refrigerator compartment is stored at low temperature.
이때, 냉동실의 냉기가 유입되도록 냉각 덕트(3)는 냉동실과 유체소통 가능하게 연결되어 있어, 냉동실에 설치된 냉각팬(6)에 의해 송풍된 냉기가 유입된다. 더욱이, 상기 냉각팬에 의해 송풍된 냉기는 냉장실 내상벽(7)에 형성된 냉기 토출구(4)를 통해 냉장실로 유입됨으로써 냉장실에 저장된 물품을 저온으로 유지시켰다.At this time, the cooling duct 3 is connected in fluid communication with the freezing compartment so that the cold air of the freezing compartment flows, and the cold air blown by the cooling fan 6 installed in the freezing compartment flows in. Furthermore, the cold air blown by the cooling fan was introduced into the refrigerating chamber through the cold air discharge port 4 formed in the upper wall 7 of the refrigerating chamber, thereby keeping the article stored in the refrigerating chamber at a low temperature.
그러나, 상기된 바와 같은 냉장고의 냉각 덕트는 냉동실의 냉기를 냉장실로 유입시키는 통로로 사용될 뿐 냉장실의 고내의 전체 걸쳐 고루 분산시키지 못함으로써 냉기를 강제적으로 순환시키도록 냉각팬이 냉동실에 설치되어야 했고, 더욱이 이러한 경우에도 냉장고 선반에 물품이 놓여진 경우에는 그 물품에 의해 냉기의 흐름이 방해되어 냉기가 용이하게 전달되지 못하여 냉장실 고내 온도의 편차를 발생시키는 문제가 있었다.However, the cooling duct of the refrigerator as described above was used as a passage for introducing the cold air of the freezer compartment into the refrigerating compartment, and a cooling fan had to be installed in the freezer compartment to force circulation of the cold air by not evenly distributing it throughout the inside of the refrigerating compartment. Moreover, even in this case, when the article is placed on the refrigerator shelf, the flow of cold air is disturbed by the article, and thus the cold air cannot be easily transferred, thereby causing a variation in the temperature in the refrigerator compartment.
따라서, 본 고안은 냉각 덕트로부터 전달된 냉기가 냉장실 전체에 걸쳐 고루 분산되어 냉장실 고내 온도의 편차를 줄일 수 있는 구조를 갖는 냉장고 선반을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a refrigerator shelf having a structure in which cold air delivered from a cooling duct is evenly distributed throughout the refrigerating compartment to reduce the variation in the temperature in the refrigerating compartment.
