본 고안은 냉장고의 증발기구조에 관한 것으로, 특히, 냉장 및 냉동실로부터 흡입되는 공조공기를 서로 분리시켜 각기 다른 온도대에서 열교환을 이룰 수 있게 함으로써, 각 실의 저장특성에 따라 열교환효율을 극대화할 수 있게 하는 냉장고의 증발기구조에 관한한 것이다.The present invention relates to an evaporator structure of a refrigerator, and in particular, by separating the air conditioning air sucked from the refrigerating and freezing compartment with each other to achieve heat exchange at different temperatures, it is possible to maximize the heat exchange efficiency according to the storage characteristics of each chamber To the evaporator structure of the refrigerator.
냉장고는 각종 식품을 냉동, 냉장 상태로 저장하여 장시간 신선도를 유지시키는데 사용되는 것으로, 그러한 냉장고는 냉동싸이클의 증발기를 식품저장공간에 설치하여 직접열교환을 이루게하는 직접냉각방식과, 증발기를 식품저장공간으로부터 격리된 통로상에 설치하여 증발기를 통해 열교환된 냉기를 냉각판의 송풍력에 의해 강제로 순환시켜 저장된 식품을 냉각시키는 간접냉각방식이 사용되고 있다.Refrigerators are used to store various foods in a frozen and refrigerated state to maintain freshness for a long time. Such refrigerators include a direct cooling method for direct heat exchange by installing an evaporator of a refrigeration cycle in a food storage space, and a food storage space for an evaporator. Indirect cooling is used to cool the stored food by forcibly circulating cold air that has been heat-exchanged through an evaporator by the blowing force of the cooling plate.
이러한 간냉식 냉장고는 제4도에 도시된 바와같이 냉장고본체(1)의 중앙부에 분리벽(7)을 횡방향으로 설치하여 냉동실(2)과 냉동실(3)을 상하로 격리되게 구성하고, 상기 분리벽(7)의 내부에는 증발기(4)를 설치하여, 그 직후방에는 공조공기를 냉장실(2)와 냉동실(3)로 강제로 송풍시키는 냉각팬(5)이 장착된다.In the intercooled refrigerator, as illustrated in FIG. 4, the separation wall 7 is installed at the center of the refrigerator body 1 in the transverse direction so that the freezer compartment 2 and the freezer compartment 3 are vertically separated from each other. An evaporator 4 is provided inside the wall 7, and immediately after that, a cooling fan 5 for forcibly blowing air to the refrigerating chamber 2 and the freezing chamber 3 is mounted.
이와같이 구성되는 냉장고에 있어 종래의 증발기는 상부에서 하부로 냉매를 유도하여 회류시키는 냉매파이프가 다수의 전열판에 지그자그식으로 절곡배관되어 분리벽(7)내부공간에 수평으로 설치되는 것이다.In the refrigerator configured as described above, the conventional evaporator is a refrigerant pipe for guiding and circulating the refrigerant from the top to the bottom by zigzag bending the pipes in a plurality of heat plates to be installed horizontally in the inner space of the separation wall (7).
그런데 상기에서와 같은 종래의 증발기는 온도차이를 가지고 있는 냉장, 냉동실의 공조공기를 함께 통과시키면서 증발기의 냉매파이프로 통과되는 혼합냉매와 열교환을 이루게 될때 높고 낮은 두 온도가 간섭되는 현상이 발생하고, 또한 냉매파이프로 유입되어 흐르는 혼합냉매의 흐름방향이 공조공기를 흐름방향과 동일하게 증발기의 후단에 이른 공조공기가 이미 증발기의 선단에서 주위열을 흡수하여 기화된 혼합냉매의 열교환을 이루게 되므로써 열교환율이 저하될 뿐만 아니라 각기 다른 온도를 유지하여 냉동 및 냉각상태로 식품을 저장해야 하는 냉장실과 냉동실의 저장특성이 상실되는 문제점이 있었다.By the way, the conventional evaporator as mentioned above occurs when the heat exchange with the mixed refrigerant passing through the refrigerant pipe of the evaporator while passing through the air conditioning air of the refrigerating and freezing chamber having a temperature difference, the high and low temperature interference occurs, In addition, the airflow rate of the mixed refrigerant flowing into the refrigerant pipe is the same as that of the airflow, so that the airflow that reaches the rear end of the evaporator has already absorbed the ambient heat at the tip of the evaporator to achieve heat exchange of the vaporized mixed refrigerant. In addition to the deterioration, there is a problem in that the storage characteristics of the refrigerating compartment and the freezing compartment which have to store foods at different temperatures by maintaining different temperatures are lost.
이에 본 고안은 상술한 바와같은 종래의 제반결함을 감안하여 이루어진 것으로, 그 목적은 냉장실과 냉동실의 저장특성에 따른 열교환효율을 극대화할 수 있게 하는 냉장고의 증발기구조를 제공함에 있다.Accordingly, the present invention has been made in view of the above-mentioned general defects, and an object thereof is to provide an evaporator structure of a refrigerator capable of maximizing heat exchange efficiency according to storage characteristics of a refrigerator compartment and a freezer compartment.
상기 목적을 달성하기 위하여 본 고안은 냉장실과 냉동실을 상호 격리 냉각실과 냉동실을 상호 격리하는 분리벽 내부가 분리판에 의해 냉장실 및 냉동실과 각각 연통되는 상, 하부공간으로 구획되고 상기 각 상, 하부공간에 저온냉매가 흐르는 냉매파이프가 설치된 증발기에 있어서, 상기 냉동실과 연통된 냉매파이프의 직경이 상기 냉장실과 연통된 냉매파이프의 직경보다 크게 하고, 상기 각 냉매파이프를 흐르는 냉매의 흐름방향과 상기 냉장실 및 냉동실을 순환하는 공조공기의 흐름방향이 서로 반대방향인 특징이 있다.In order to achieve the above object, the present invention separates the refrigerating compartment and the freezing compartment from each other. The interior of the partition wall separating the refrigeration compartment and the freezing compartment from each other is divided into upper and lower spaces communicating with the refrigerating compartment and the freezing compartment, respectively. An evaporator provided with a refrigerant pipe in which a low temperature refrigerant flows, wherein the diameter of the refrigerant pipe communicating with the freezing compartment is larger than the diameter of the refrigerant pipe communicating with the refrigerating compartment, and the flow direction of the refrigerant flowing through each refrigerant pipe and the refrigerating compartment and The flow direction of the air conditioning air circulating in the freezing compartment is characterized in that the opposite direction.
이하, 첨부된 도면에 의거하여 본 고안 일실시예의 구성을 상세히 설명하면 다음과 같다.Hereinafter, the configuration of an embodiment of the present invention in detail with reference to the accompanying drawings.
제1도는 본 고안이 적용된 냉장고의 개략단면도로서, 이 냉장고는 통상에서와 같이 본체(1)중앙의 중간벽(7)에 의해 냉장실(2)과 냉동실(3)이 분리 구성되고, 상기 중간벽(7)내에는 냉장실(2)과 냉동실(3)로부터 유입되는 공조공기와 열교환을 이루게 하는 증발기(400)가 수평형으로 냉장되는 것이며, 상기 증발기(400)의 직후방에는 공조공기를 각 실내로 강제 순환시키는 냉장팬(5)이 구성되는 것이다.FIG. 1 is a schematic cross-sectional view of a refrigerator to which the present invention is applied. The refrigerator includes a refrigerator compartment 2 and a freezer compartment 3 separated by an intermediate wall 7 in the center of the body 1 as usual. In (7), the evaporator 400 for heat exchange with the air conditioning air introduced from the refrigerating chamber 2 and the freezing chamber 3 is refrigerated horizontally, and immediately after the evaporator 400, the air conditioning air is stored in each room. The refrigeration fan (5) forcibly circulating in the configuration.
이러한 냉장고에 있어 본고안 증발기(400)는 제2도에서와 같이 상기 중간벽(7)내에 판체상의 분리판(430)을 횡설하여 그 상, 하부가 냉장, 냉동실(2,3)과 연통되도록 구획시키며, 상기 분리판(430)의 상, 하부에는 냉매파이프(410)(420)를 카운터플로우(Counter Flow)방식, 즉, 혼합냉매의 흐름방향이 공조공기의 흐름방향과 반대방향이 되도록 배관하게 된다.In such a refrigerator, the evaporator 400 of the present invention rolls up a plate-shaped separator 430 in the intermediate wall 7 as shown in FIG. 2 so that the upper and lower portions thereof communicate with the refrigerating and freezing chambers 2 and 3. The refrigerant pipes 410 and 420 are arranged in the upper and lower portions of the separation plate 430 so that the flow direction of the mixed refrigerant is opposite to the flow direction of the air conditioning air. Done.
이때 냉장실(2)에 비하여 저온을 유지하여야 하는 냉동실(3)로 냉각팬(5)에 의해 유동되는 많은량의 냉기를 안내할 수 있도록 상기 분리판(430)의 후단을 냉동실(3)의 반대방향으로 만곡되게 절곡시킨다.At this time, the rear end of the separating plate 430 is opposite to the freezer compartment 3 so as to guide a large amount of cold air flowing by the cooling fan 5 to the freezer compartment 3 which should be kept at a lower temperature than the freezer compartment 2. Bend in the direction.
또한 상기 분리판(430)에 의해 분리된 두공간 중에서 냉장실(2)과 연통되는 상부공간에 위치하는 냉매파이프(410)는 작은 직경으로 하고 냉동실(3)과 연통되는 하부공간에는 다소 큰 직경으로 하여 혼합냉매의 유입량이 많도록 구성하게 되는 것이다.In addition, the refrigerant pipe 410 located in the upper space communicating with the refrigerating chamber 2 among the two spaces separated by the separating plate 430 has a small diameter and has a rather large diameter in the lower space communicating with the freezing chamber 3. In this case, the inflow of the mixed refrigerant is large.
이상에서와 같이 결합구성된 본 고안 증발기에 의한 열교환과정과 그에 따른 작용효과를 상세히 설명하면 다음과 같다.When described in detail the heat exchange process and the effect according to the present invention evaporator coupled configuration as described above as follows.
먼저 냉동싸이클의 압축기(6)로부터 고온고압으로 압축된 기체냉매가 응축기(미도시)에서 주위공기와 열교환되어 상온의 액체상태로 변하게 되고, 이러한 액상의 냉매는 모세관(미도시)을 통과하면서 저온저압의 상태로 감압되어 증발기(400)의 냉매파이프(410,420)로 유입된다.First, the gas refrigerant compressed to high temperature and high pressure from the compressor 6 of the refrigeration cycle is exchanged with ambient air in a condenser (not shown) to change into a liquid state at room temperature, and the liquid refrigerant passes through a capillary tube (not shown). The pressure is reduced to a low pressure and flows into the refrigerant pipes 410 and 420 of the evaporator 400.
이러한 과정을 통하여 증발기(400)의 냉매파이프(410,420)로 저온저압의 기체냉매가 통과하는 상태에서 냉장실(2)과 냉동실(3)로 순환된 공조공기가 중간벽(7)의 흡입구(40)를 통해 각각 흡입되면, 이 공조공기는 제3도에서와 같이 분리판(430)에 의해 상, 하부로 분리된 상태로 증발기(400)를 통과하면서 열교환을 이루게 된다.Through this process, the air conditioning air circulated to the refrigerating compartment 2 and the freezing compartment 3 in the state where the low-temperature low-pressure gas refrigerant passes through the refrigerant pipes 410 and 420 of the evaporator 400 is the inlet 40 of the intermediate wall 7. When each is sucked through, the air conditioning is heat exchange while passing through the evaporator 400 in a state separated into the upper, lower by the separating plate 430 as shown in FIG.
이와같이 열교환을 이루는 과정에서 냉장실(2)로부터 유입된 공조공기는 작은 직경의 냉매파이프(410)를 통과하게 되므로써 냉장실의 저장특성에 맞는 온도로 열교환을 이룬후 냉장실(2)로 급기되는 것이며, 냉동실(3)로부터 유입된 공조공기는 상기 냉매파이프(410)보다 큰 직경의 냉매파이프(420)를 통과하게 되므로써 냉동실의 저장특성에 맞는 비교적 낮은 온도로 열교환을 이룬후 냉동실(3)로 급기된다.In this way, the air-conditioning air introduced from the refrigerating chamber 2 passes through the refrigerant pipe 410 having a small diameter so as to exchange heat at a temperature suitable for the storage characteristics of the refrigerating chamber, and is then supplied to the refrigerating chamber 2. The air-conditioning air introduced from (3) passes through the refrigerant pipe 420 having a diameter larger than that of the refrigerant pipe 410, thereby performing heat exchange at a relatively low temperature suitable for the storage characteristics of the freezer compartment, and then is supplied to the freezer compartment (3).
이때 증발기(400)와 열교환되는 공조공기는 냉매파이프(410,420)를 통과하는 혼합냉매의 흐름방향과 반대방향으로 흐르게 되므로써 증발기(400)의 후단에 이른 공조공기가 각 냉매파이프(410,420)의 선단으로 유입되는 혼합냉매와 열교환을 이루게 되는 것이며, 냉각팬(5)으로부터 발생하는 송풍력은 그 전방에 상향으로 만곡지게 절곡된 반대방향으로 강하게 작용되므로써 냉장실(2)측에 비하여 많은 량의 냉기가 냉동실(3)측으로 급기되는 것이다.At this time, the air conditioning heat exchanged with the evaporator 400 flows in the direction opposite to the flow direction of the mixed refrigerant passing through the refrigerant pipes 410 and 420, so that the air conditioning air reaching the rear end of the evaporator 400 is the front end of each refrigerant pipe 410 and 420. The heat exchange with the mixed refrigerant flows in, and the blowing force generated from the cooling fan 5 acts strongly in the opposite direction bent upwardly in front of it, so that a large amount of cold air is more than that of the refrigerator compartment 2 side. It is supplied to (3) side.
따라서 본 고안은 냉장 및 냉동실로부터 흡입되는 공조공기를 서로 분리시켜 각기 다른 온도대에서 열교환을 이룰 수 있게함과 동시에 공조공기와 혼합냉매의 흐름방향을 서로 반대로 하므로써 냉장실과 냉동실의 저장특성에 따른 열교환효율을 극대화 할수 있게 함을 특징으로 하는 것이다.Therefore, the present invention separates the air-conditioning air sucked from the refrigerating and freezing compartments from each other to achieve heat exchange at different temperature ranges and at the same time reverses the flow direction of the air-conditioning air and the mixed refrigerant. It is characterized by maximizing efficiency.
