본 고안은 냉장고 중간벽 열차단장치, 더욱 상세하게는 냉동실과 냉장실을 구분하게 설치된 중간벽의 단열효율을 향상시키는 한편 부피를 축소시켜 내부용적을 증대시킬 수 있게 한 냉장고 중간벽 열차단장치에 관한 것이다.The present invention relates to a refrigerator intermediate wall thermal barrier device, and more particularly to a refrigerator intermediate wall thermal barrier device, which can increase the internal volume by reducing the volume while improving the thermal insulation efficiency of the intermediate wall installed to separate the freezer compartment and the refrigerator compartment. will be.

일반적으로, 냉장고는 냉매의 냉동사이클에 의해 고내에 냉기를 공급하여 음식물을 신선하게 보관하게 된 것으로, 제1도에서와 같이 고내에 중간벽(3)을 설치하여 냉기의 온도 및 공급량을 다르게 함으로써 냉동실(1)과 냉장실(2)로 구분된다.In general, the refrigerator is to cool the food in the refrigerator by the refrigeration cycle of the refrigerant to keep the food fresh, by installing an intermediate wall (3) in the refrigerator as shown in Figure 1 by varying the temperature and supply of cold air It is divided into a freezer compartment 1 and a refrigerating compartment 2.

상기 중간벽(3)에 의해 형성되는 냉동실(1)은 통상 -5℃∼-24℃의 온도를 유지하여 냉동식품등을 보존하며, 냉장실(2)은 -3℃∼-10℃ 정도의 온도를 유지하여 냉장식품과 야채 및 과일등을 보존한다.The freezer compartment 1 formed by the intermediate wall 3 generally maintains a temperature of -5 ° C to -24 ° C to store frozen foods, and the refrigerating chamber 2 has a temperature of about -3 ° C to -10 ° C. Maintain preservation of refrigerated foods, vegetables and fruits.

또한, 냉동실(1) 및 냉장실(2)을 세분화 하기 위한 중간벽도 설치하였다.In addition, an intermediate wall for subdividing the freezing chamber 1 and the refrigerating chamber 2 was also provided.

한편, 제 2도는 상기 냉동실과 냉장실을 구분하는 중간벽의 일예를 나타낸 단면도로서, 이 중간벽(3)은 외부에 형성된 케이스(4)의 내부공간에 우레탄 수지를 발포 및 경화시켜 단열층(5)을 형성한 구조로 되어 있다.On the other hand, Figure 2 is a cross-sectional view showing an example of the intermediate wall that separates the freezer compartment and the refrigerating compartment, this intermediate wall 3 is a heat insulating layer (5) by foaming and curing the urethane resin in the inner space of the case (4) formed on the outside It has a structure formed.

이 단열층(5)은 온도차가 약 30℃ 내외인 냉동실(1)과 냉장실(2)의 열전도를 차단하는 작용을 하였으나, 단열기능이 미흡하여 부분적인 열교환이 빈번히 발생하였다.The heat insulation layer 5 blocks the heat conduction between the freezer compartment 1 and the refrigerating compartment 2 having a temperature difference of about 30 ° C., but partial heat exchange occurs frequently due to the insufficient heat insulation function.

이러한 열교환 현상은 냉장실측에 이슬이나 결빙 및 과냉각을 유발하여 냉장실에 보존된 식품에 악영향을 주게되었고, 냉동실측에는 온도가 저하되면서 냉동사이클의 부하를 증가시켜 소비전력을 늘어나게 하는 등의 비경제적인 영향을 주게 된다.This heat exchange phenomenon adversely affects the food stored in the refrigerating compartment by causing dew, freezing, and supercooling on the refrigerating compartment side. On the freezing compartment side, the temperature decreases, increasing the load of the refrigerating cycle and increasing power consumption. Given.

상기의 열교환을 방지하기 위해 통상적인 중간벽의 두께(110㎜)보다 증가시켜 제작할 경우에는 두께의 증가에 비례하여 냉동 및 냉장실의 내부 용적이 줄어들게 되는 문제점이 있었다.In order to prevent the heat exchange, if the fabrication is made to increase the thickness of the conventional intermediate wall (110 mm), there is a problem that the internal volume of the freezing and refrigerating chamber is reduced in proportion to the increase of the thickness.

본 고안은 상기와 같은 종래의 냉장고용 중간벽의 단열구조의 문제점을 해결하기 위해 안출된 것으로, 냉장실과 냉동실의 열 전도를 차단하고 고내의 용적을 증대시킬 수 있는 냉장고 중간벽 열차단장치를 제공함을 목적으로 한다.The present invention has been devised to solve the problems of the conventional thermal insulation structure of the intermediate wall for the refrigerator, and provides a refrigerator intermediate wall thermal barrier device that can block the heat conduction of the refrigerating compartment and the freezing compartment and increase the volume in the refrigerator. For the purpose.

이러한 본 고안의 목적은 중간벽의 내부에 열차단부재를 착설함으로써 달성된다.The object of this invention is achieved by installing a thermal barrier member inside the intermediate wall.

즉, 중간벽을 형성하는 케이스의 내부에 판체 혹은 진공실을 갖춘 판체로 된 열차단 부재를 설치하여 냉동실과 냉장실의 열전도를 보다 정확하게 차단하고 중간벽의 두께를 줄일수 있게한 것을 특징으로 한다.That is, by installing a heat shield member made of a plate body or a plate having a vacuum chamber inside the case forming the intermediate wall, it is possible to more accurately block the heat conduction of the freezer compartment and the refrigerating compartment and to reduce the thickness of the intermediate wall.

이하, 본 고안의 냉장고 중간벽 열차단장치의 단열구조를 첨부된 도면에 의거 하여 상세히 설명한다.Hereinafter, the insulation structure of the refrigerator intermediate wall heat shield device of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 고안의 실시예의 중간벽 열차단장치의 단열구조를 나타낸 것으로, 냉동실(1)과 냉장실(2)을 구분하게 설치되는 중간벽(10)은 적정두께의 공간부를 갖춘 케이스(11)로 구성되며, 이 벽케이스의 일측면에는 고내와의 온도차로 인한 결로를 방지하도록 히트파이프(12)가 배관되어 있다.3 is a heat insulation structure of the intermediate wall heat shield device according to the embodiment of the present invention, wherein the intermediate wall 10 installed to separate the freezer compartment 1 and the refrigerating compartment 2 has a case 11 having a space having an appropriate thickness. The heat pipe 12 is piped on one side of the wall case to prevent condensation due to a temperature difference with the inside of the refrigerator.

한편, 상기 벽케이스(11)내의 내벽 사이에 형성된 공간부에는 열교환을 차단하는 열차단부재(20)가 판체로 설치되며, 이 열차단부재의 양면에는 적어도 하나의 완충판(21)이 개재되어 있다.On the other hand, in the space formed between the inner wall in the wall case 11, a heat shield member 20 for blocking heat exchange is installed in a plate body, at least one buffer plate 21 is interposed on both sides of the heat shield member. .

즉, 상기의 박판의 열차단부재(20)는 내면에 열접촉을 차단하는 진공실을 형성하여 냉장실(2)의 고온이 냉동실(1)의 저온으로 열 이동하는 것을 차단한다.That is, the thermal barrier member 20 of the thin plate forms a vacuum chamber for blocking thermal contact on the inner surface to block the high temperature of the refrigerating chamber 2 from being thermally moved to the low temperature of the freezing chamber 1.

따라서, 상기의 열차단부재(20)는 종래 단열층 보다 얇은 두께로도 우수한 단열효과를 발휘하며, 이 열차단부재가 설치된 중간벽(10)은 종래 110㎜이던 중간벽의 두께를 약 40㎜ 줄여 170㎜로 형성할 수 있어서 고내의 내부용적을 30Liter 이상 늘려준다.Therefore, the heat shield member 20 exhibits excellent heat insulation effect even at a thickness thinner than the conventional heat insulation layer, and the intermediate wall 10 provided with the heat shield member reduces the thickness of the middle wall, which was 110 mm, by about 40 mm. It can be formed to 170mm, increasing the internal volume of the interior more than 30 liters.

한편, 상기 열차단부재(20)의 표면에 홈을 형성하거나, 진공실에 칸막이를 설치하여 열차단부재의 강도를 높여 주어도 무방하며, 상기 완충판(21) 대신에 우레탄등의 단열재로 발포 성형하여도 무방하다.On the other hand, a groove may be formed on the surface of the heat shield member 20 or a partition may be provided in a vacuum chamber to increase the strength of the heat shield member, and instead of the buffer plate 21, foam molding may be performed using a heat insulating material such as urethane. It's okay.

상기와 같은 본 고안의 열차단부재(20)가 구비된 중간벽(10)은 종래와 같이 냉장고의 냉동실(1)과 냉장실(2) 사이에 설치되어, 고온의 냉장실(2)의 열이 저온의 냉장실(1)로 전도되는 것을 차단하여 각실이 균일한 온도로 유지할 수 있게 한다.The intermediate wall 10 provided with the heat shield member 20 of the present invention as described above is installed between the freezing chamber 1 and the refrigerating chamber 2 of the refrigerator as in the prior art, so that the heat of the high temperature refrigerating chamber 2 is low. Blocking the conduction of the refrigerating chamber (1) of each to maintain a uniform temperature.

또한 상기 열차단부재(20)는 종래 단열재를 사용할 때보다 중간벽(10)의 부피를 슬림화하여 내부용적을 넓혀 주며, 반영구적으로 사용할 수 있어서 중간벽의 냉장실측 면에 형성되던 결로와 결빙 및 과냉동을 방지한다.In addition, the thermal barrier member 20 increases the internal volume by slimming the volume of the intermediate wall 10 than when using a conventional heat insulator, and can be used semi-permanently. Prevent copper.

상기와 같은 본 고안의 중간벽은 냉동실과 냉장실의 열전도를 차단하여 각 실이 균일한 온도를 유지할 수 있게하여 냉장고의 가동시간을 줄여줌으로써 전기료를 절감하는 효과가 있다.Intermediate wall of the present invention as described above has the effect of reducing the electric charge by reducing the operating time of the refrigerator by blocking the heat conduction of the freezer compartment and the refrigerating compartment to maintain a uniform temperature of each chamber.
