본 고안은 냉장고에 관한 것으로, 특히 직냉식 판형 증발기를 식품저장실(냉동실 또는 냉장실)을 좌우로 양분하도록 설치하여 적어도 그 양면에서 열교환이 이루어지게 함으로써 냉동능력을 향상시킨 직냉식 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a direct-cooling refrigerator having a refrigeration capacity by installing a direct-cooling plate evaporator to bisect the food storage compartment (freezer or refrigerating compartment) to the left and right to perform heat exchange on at least both sides thereof.

종래의 직냉식 냉장고는, 제1도에 도시한 바와 같이, 중간격벽(1)에 의해 냉동실(2)과 냉장실(2')로 구획된 식품저장실을 갖는 냉장고 본체(3)에 냉동실도아(4)와 냉장실도아(4')가 설치되어 구성된다.In the conventional direct-cooling refrigerator, as shown in FIG. 1, a freezer compartment 4 is provided in a refrigerator main body 3 having a food storage compartment divided into a freezing compartment 2 and a refrigerating compartment 2 'by an intermediate partition 1. And a refrigerating chamber door 4 '.

냉동실(2)과 냉장실(2')의 후방에는 직냉식 증발기(5)가 설치되고 본체(3) 하방에는 압축기(6)가 설치된다.A direct cooling evaporator 5 is provided at the rear of the freezing chamber 2 and the refrigerating chamber 2 ', and a compressor 6 is installed below the main body 3.

이 직냉식 증발기(5)는 판형(plate-type)으로 형성되어 냉동실(2)과 냉장실(2')의 후면에 설치되는데, 이 직냉식 증발기(5)의 측면에는 제상히터(7)가 설치되고 그 하방에는 제상수받이(8)가 설치된다. (9)은 제상수를 외부로 배출하기 위한 배수관이다.The direct-cooling evaporator 5 is formed in a plate-type and is installed at the rear of the freezing chamber 2 and the refrigerating chamber 2 ', and a defrost heater 7 is installed on the side of the direct-cooling evaporator 5. The defrosting receiver 8 is installed below. (9) is a drain pipe for discharging defrost water to the outside.

이러한 직냉식 냉장고에서는 간냉식 증발기인 핀형(fin-type) 증발기를 사용하는 간냉식 냉장고와는 달리 고내에 냉기순환유로가 없다.In the direct-cooling refrigerator, unlike the cold-cooling refrigerator using a fin-type evaporator, which is an intercooling evaporator, there is no cold air circulation path in the refrigerator.

즉 고내의 냉기는 제1도에 화살표로 나타낸 바와 같이, 직냉식 증발기와 직접열교환을 이루어 자연대류에 의해 냉기로 되는 것이다.In other words, the cold air in the refrigerator is directly heat exchanged with the direct-cooling evaporator, as indicated by the arrow in FIG. 1, to be cold by natural convection.

이러한 종래의 직냉식 냉장고는 자연대류에 의한 냉각방식으로 고내를 냉각시키므로 간냉식 냉장고보다 냉각시간이 길어지고 증발기가 위치한 냉동실과 냉장실의 후면에서 냉장고 앞면쪽으로의 냉기순환이 충분히 이루어지지 않아 필요에 따라 팬을 추가해야 하는 문제점이 있었다. 또한 직냉식 증발기가 냉장실과 냉동실의 후면에 설치되므로 증발기의 한면만이 고내공기와 열교환을 하게 되고 이에 따라 다른면에서는 에너지 손실이 생기게 되어 냉동능력이 떨어지는 문제점이 있었다.Since the conventional direct-cooling refrigerator cools the inside of the refrigerator by a natural convection cooling method, the cooling time is longer than that of the inter-cooling refrigerator, and the cooling air circulation from the rear of the freezer and the refrigerating compartment where the evaporator is located to the front of the refrigerator is not sufficient. There was a problem that needs to be added. In addition, since the direct-cooling evaporator is installed at the rear of the refrigerating chamber and the freezing chamber, only one side of the evaporator exchanges heat with the air in the high temperature, resulting in energy loss on the other side, thus reducing the freezing capacity.

따라서 본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 직냉식 증발기의 양면을 사용하여 증발기의 효율을 극대화 시키고 고내 냉기의 순환공간을 최대한 감소시켜 냉동능력 및 에너지의 효율을 향상시킬 수 있는 직냉식 냉장고를 제공하는 것이다.Therefore, the present invention is to solve this problem, the purpose of the present invention is to maximize the efficiency of the evaporator by using both sides of the direct-cooled evaporator and to reduce the circulation space of the cold air as possible to improve the freezing capacity and energy efficiency It is to provide a direct-cooling refrigerator.

이러한 목적을 달성하기 위한 본 고안은, 저장실에 직냉식 증발기가 마련되어 냉동사이클을 수행하는 직냉식 냉장고에 있어서, 상기 직냉식 증발기는 상기 저장실을 좌우로 양분하여 그 양면에서 열교환이 이루어지도록 설치된 것을 특징으로 한다.The present invention for achieving the above object, in the direct-cooling refrigerator provided with a direct-cooling evaporator in the storage compartment to perform a refrigeration cycle, the direct-cooling evaporator is characterized in that the heat exchange is installed on both sides by dividing the storage compartment to the left and right.

이하에서는 첨부도면을 참조하면서 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

제2도는 본 고안의 구성도인데 제1도와 동일한 요소에 대해서는 동일 참조번호를 사용한다. 제2도에 도시된 바와 같이, 본 고안에 따른 냉장고는 중간격벽(1)에 의해 냉동실(2)과 냉장실(2')로 구획된 식품저장실을 갖는 냉장고 본체(3)에 냉동실도아(4)와 냉장실도아(4')가 설치되어 구성된다. 냉장실에는 직냉식 증발기(50)가 설치되는데, 종래의 직냉식 증발기와 달리냉장실(2')을 좌우 양쪽으로 양분하도록 설치된다.2 is a block diagram of the present invention, the same reference numerals are used for the same elements as in FIG. As shown in FIG. 2, the refrigerator according to the present invention includes a freezer compartment 4 in a refrigerator body 3 having a food storage compartment divided into a freezer compartment 2 and a refrigerator compartment 2 ′ by an intermediate partition 1. And a refrigerating chamber door 4 '. In the refrigerating chamber, a direct cooling evaporator 50 is installed. Unlike the conventional direct cooling evaporator, the refrigerating chamber 2 'is installed to bilaterally align the left and right sides.

즉 냉장실의 양측면과 소정간격을 두고 대략 평행하게 설치되는 것이다.That is, they are installed in substantially parallel with both sides of the refrigerating chamber at predetermined intervals.

이러한 직냉식 증발기를 제외한 나머지 구성은 제1도에 도시한 종래의 직냉식 증발기와 동일하다.Except for the direct cooling evaporator, the rest of the configuration is the same as that of the conventional direct cooling evaporator shown in FIG.

제3도에 도시된 바와 같이, 본 고안에 채용된 직냉식 증발기는 판형(plate-type) 증발기이며 그 양측면에는 격자판(51)이 설치된다. 이 격자판은 증발기의 양면과 수납되는 식품 또는 음식물과의 접촉을 방지함과 동시에 증발기 양면과 고내의 냉기와의 자연대류가 원활히 이루어지도록 하기 위한 것으로 이러한 목적을 충분히 달성할 수 있는 적절한 크기의 격자로 구성되는 것이 바람직하다. 또한 격자판(51)에는 식품을 올려 놓는 선반을 지지할 수 있는 받침턱(52)이 마련된다. 이러한 받침턱(52)은 선반의 수에 따라 다수개가 마련될 수 있다. 증발기(50)와 격자판(51)사이의 증발기 양면에는 제상히타(53)가 설치되며 증발기의 하측에는 제상수받이(54)가 설치된다. 이 증발기 조립체는 받침대(55)에 의해 냉장실(2')에 설치되는데, 이 받침대는 냉장실의 후면측에 설치되어 증발기(50)의 하측을 지지한다.As shown in FIG. 3, the direct-cooling evaporator employed in the present invention is a plate-type evaporator, and grating plates 51 are provided on both sides thereof. The grating is designed to prevent the contact between both sides of the evaporator and the food or food stored in it, and to facilitate the natural convection between both sides of the evaporator and the cold inside the oven. It is preferred to be configured. In addition, the grid plate 51 is provided with a support jaw 52 that can support the shelf on which the food is placed. The base jaw 52 may be provided in plurality depending on the number of shelves. Defrost heaters 53 are installed on both sides of the evaporator between the evaporator 50 and the grid 51, and a defrosting receiver 54 is installed below the evaporator. This evaporator assembly is installed in the refrigerating compartment 2 'by the pedestal 55, which is installed on the rear side of the refrigerating compartment to support the lower side of the evaporator 50.

이러한 증발기는 다수개가 설치될 수도 있고 본 실시예에서와 같이 하나만 설치될 수도 있다. 이는 냉장고의 사양에 따라 결정된다. 또한 증발기의 크기는 냉장실의 폭과 깊이에 따라 결정된다.A plurality of such evaporators may be installed or only one may be installed as in this embodiment. This depends on the specifications of the refrigerator. The size of the evaporator also depends on the width and depth of the refrigerator compartment.

한편, 도시하지는 않았지만 냉기의 순환을 강제시키기 위해 팬을 증발기의 상측 또는 하측에 설치할 수 있다.On the other hand, although not shown, a fan may be installed above or below the evaporator to force circulation of cold air.

이와 같이 구성된 본 고안에 따른 직냉식 냉장고의 작용을 설명하면 다음과 같다.Referring to the operation of the direct-cooling refrigerator according to the present invention configured as described above are as follows.

증발기(50)가 작동함에 따라 증발기의 내부를 흐르는 냉매의 증발작용으로 고내의 열을 흡수함으로써 냉기를 생성하고 이 냉기는 제4도에 도시한 바와 같이 증발기를 중심으로 양쪽에서 고내를 순환한다. 즉 증발기의 양면에서 열교환이 이루어지므로 열교환율이 높은 뿐만 아니라 증발기의 양면에서 자연대류가 이루어지므로 냉기순환이 종래에 비해 훨씬 용이하게 된다. 이와 동시에 증발기가 냉장실을 양분하므로 냉기순환공간이 감소되어 보다 신속하고 완전하게 냉기순환이 이루어진다. 한편 제상시에는 제상히타(53)가 작동되어 제상을 수행하고 이 제상작용으로 생긴 제상수는 일단 제상수받이(54)에 모인 후 별도의 배수관에 의해 고외로 배출된다.As the evaporator 50 operates, cold air is generated by absorbing heat in the refrigerator by the evaporation of the refrigerant flowing through the inside of the evaporator, and the cold air circulates in the refrigerator from both sides around the evaporator as shown in FIG. That is, since the heat exchange is performed on both sides of the evaporator, not only the heat exchange rate is high, but also natural convection occurs on both sides of the evaporator, thereby making the cold air circulation much easier than in the related art. At the same time, since the evaporator bisects the refrigerating chamber, the cold air circulation space is reduced, thereby making the cold air circulation more quickly and completely. Meanwhile, during defrosting, the defrost heater 53 is operated to perform defrosting, and the defrost water generated by the defrosting action is collected in the defrosting receiver 54 and then discharged to the outside by a separate drain pipe.

본 실시예에서는 직냉식 증발기가 냉장실에 설치되는 것으로만 설명하였지만 냉동실에도 동일한 구성으로 설치될 수 있음은 물론이다.In this embodiment, the direct-cooling evaporator has been described as being installed only in the refrigerating chamber, but of course, the freezing chamber may be installed in the same configuration.

제5도는 본 고안의 다른 실시예를 도시한 것으로, 증발기의 구성은 상기한 실시예와 동일하며 다만 냉장실 도아 및 냉동실 도아가 2개로 양쪽에서 개폐할 수 있는 구조의 냉장고에도 본 고안이 적용될 수 있음을 나타낸 것이다.5 is a view showing another embodiment of the present invention, the configuration of the evaporator is the same as the above embodiment, but the present invention can be applied to a refrigerator having a structure that can be opened and closed from both sides of the refrigerator compartment door and the freezer compartment door. It is shown.

이상에서 상세히 설명한 바와 같이, 본 고안에 따른 직냉식 냉장고에 의하면, 증발기의 양면에서 열교환 및 자연대류가 이루어지므로 한쪽면에서만 열교환 및 자연대류가 이루어지는 동일한 크기의 종래 직냉식 냉장고에 비해 증발기 효율이 높아지며 이에 따라 에너지효율의 향상을 꾀할 수 있다. 또한 크기가 작은 증발기로도 종래와 동일한 성능을 가지도록 구성할 수 있으므로 크기가 작아짐에 따른 제작비용이 줄어들게 된다.As described in detail above, according to the direct-cooling refrigerator according to the present invention, since the heat exchange and natural convection is made on both sides of the evaporator, the evaporator efficiency is higher than that of the conventional direct-cooling refrigerator of the same size where heat exchange and natural convection are performed only on one side. The energy efficiency can be improved. In addition, even a small evaporator can be configured to have the same performance as the prior art, the manufacturing cost is reduced as the size is reduced.
