본 고안은 냉장실 및 냉동실의 내측에 각각 증발기를 설치하여 자연대류에 의해 냉기를 순환시키는 직냉식 냉장고에 관한것으로, 더욱 상세하게는 단열재의 발포성형시 내상판의 변형을 방지할 수 있도록된 냉장고용 내상판구조에 관한것이다.The present invention relates to a direct-cooling refrigerator that circulates cold air by natural convection by installing an evaporator inside the refrigerating compartment and the freezing compartment, and more particularly, a refrigerator for preventing deformation of the inner plate during foaming of the insulating material. It is about the top structure.
일반적으로 전기냉장고는 고내의 냉각방식에 따라 냉기를 자연대류에 의해 순환시키는 자연대류방식(또는 직냉식)과, 냉장실 및 냉동실 이외의 곳에 증발기를 설치하여 팬의 작동에 따라 냉기를 강제순환시키는 강제순환방식(또는 팬식)으로 대별되어 진다.In general, the electric refrigerator is a natural convection method (or direct cooling) that circulates cold air by natural convection according to a cooling method in a refrigerator, and a forced circulation to force circulation of cold air according to the operation of a fan by installing an evaporator in a refrigerator or freezing room It is roughly divided into methods (or fans).
종래의 직냉식 냉장고는 제1도 및 제2도에 도시한 바와같이 내상판(1a) 및 외상판(1b)이 소정의 간격을 두고 형성됨과 동시에 그 내측에는 단열재(2)를 충진시킨 냉장고 본체(1)의 내측에는 냉장실(3)이 형성되어 있고, 상기 냉장실(3)의 내측면에는 압축기(4)에서 고온고압으로 압축된 기체냉매가 응축기(5)에서 상온고압의 액냉매로 되어 열을 방출한후 도시하지 않은 감압수단에 의해 감압되어 주위공기로 부터 열을 빼앗아 증발됨으로써 상기 냉장실(3)을 냉각시키는 증발기(6)가 설치되어 있다.In the conventional direct-cooling refrigerator, as shown in FIGS. 1 and 2, the inner body plate 1a and the outer plate 1b are formed at predetermined intervals and the inside of the refrigerator body filled with the heat insulating material 2 ( The refrigerator compartment 3 is formed inside 1), and the gas refrigerant compressed at high temperature and high pressure by the compressor 4 is a liquid refrigerant at room temperature and high pressure in the condenser 5 on the inner side of the refrigerator compartment 3 to heat. After the discharge, the evaporator 6 is provided to cool the refrigerating compartment 3 by decompressing the vacuum chamber by depressurization means (not shown) to take heat away from the ambient air.
그리고, 상기 냉장실(3)의 하측에는 야채, 과일등을 저장하기위한 저장박스(7)가 설치되어 있고, 상기 냉장실(3)의 전면에는 도어(8)가 개폐가능케 결합되어 있다.In addition, a storage box 7 for storing vegetables and fruits is provided below the refrigerating compartment 3, and a door 8 is coupled to the front of the refrigerating compartment 3 so as to be opened and closed.
따라서, 압축기(4), 응축기(5) 및 증발기(6)로 이루어지는 냉동싸이클의 작동에 따라 상기 증발기(6)의 주위에서 냉기가 형성됨으로써 냉장실(3)내에서는 냉장 또는 냉동이 이루어지게 된다.Therefore, the cold air is formed around the evaporator 6 in accordance with the operation of the refrigeration cycle consisting of the compressor 4, the condenser 5 and the evaporator 6, so that the refrigerating chamber 3 is refrigerated or frozen.
그러나, 이와같은 종래의 직냉식 냉장고에 있어서 내상판(1a)과 외상판(1b)의 사이에는 폴리우레탄등의 단열재(2)를 충진시킨후 발포성형하게 되는데, 이때에는 증발기(6)가 냉장실(3)의 내측에 설치됨에 따라 제3도 및 제4도에 도시한 바와같이 상기 내상판(1a)과, 이 내상판(1a)을 지지하는 지그판(J)의 접촉부분이 충분하지 못하게 됨으로써 액체상태로 주입되는 단열재(2)의 팽창시 작용하는 발포압력에 의해 내상판(1a)의 코너부(C)가 심하게 변형되어 불량율을 증대시킬 뿐만 아니라 이로 인하여 생산성이 현저히 저하되는 등의 여러가지 문제점이 있었다.However, in such a conventional direct-cooling refrigerator, the insulating material 2 such as polyurethane is filled between the inner plate 1a and the outer plate 1b, and then foamed. As it is installed inside 3), as shown in FIGS. 3 and 4, the contact portion between the inner upper plate 1a and the jig plate J supporting the inner upper plate 1a becomes insufficient. The corner portion C of the inner plate 1a is severely deformed by the foaming pressure acting upon the expansion of the heat insulator 2 injected into the liquid state, thereby increasing the defective rate, and thereby causing a significant decrease in productivity. There was this.
본 고안은 이와같은 종래기술의 문제점들을 해결하기 위하여 안출된것으로서, 본 고안의 목적은 단열재의 발포성형시 내상판의 변형을 방지하여 불량율을 최소화함과 동시에 생산성을 향상시킬 수 있는 냉장고용 내상판구조를 제공하는데 있다.The present invention is devised to solve the problems of the prior art, the object of the present invention is to prevent the deformation of the inner plate during the foam molding of the insulating material to minimize the defective rate and at the same time improve the productivity of the inner plate for refrigerators To provide structure.
이와같은 목적을 실현하기 위하여 이루어진 본 고안에 따른 냉장고용 내상판구조는 외상판과, 이 외상판의 내측에 소정의 간격을 두고 위치되는 내상판과, 상기 외상판과 내상판의 사이에 발포성형되는 단열재로 이루어지는 냉장고 본체를 구비하고, 상기 내상판의 내측에는 내상판에 인접하여 증발기가 배설되는 냉장고에 있어서, 상기 내상판에는 단열재(2)의 발포시 상기 증발기(6)를 감싸서 상기 내상판을 지지하는 지그판(J)과의 접촉면적을 증대시켜 변형을 방지하도록 상기 증발기(6)의 상측에는 계단부(11)가 내측으로 돌출형성된 것을 특징으로 한다.Refrigerator inner plate structure according to the present invention made to achieve the above object is a trauma plate, the inner plate is placed at a predetermined interval inside the outer plate, and the foam between the outer plate and the inner plate And a refrigerator body including a heat insulating material, the refrigerator having an evaporator disposed adjacent to the inner plate inside the inner plate, wherein the inner plate wraps the evaporator 6 when foaming the heat insulating material 2 and the inner plate. Stepped portion 11 is formed on the upper side of the evaporator 6 to protrude inward to increase the contact area with the jig plate (J) supporting the to prevent deformation.
이하, 본 고안의 바람직한 실시예를 첨부된 도면 제5도 내지 제8도에 따라서 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to FIGS. 5 to 8.
도면 제5도 및 제6도는 본 고안의 실시예에 따른 냉장고를 나타내는 도면으로서, 종래의 구성과 동일한 구성에 대해서는 동일명칭 및 동일부호를 병기하며 상세한 설명은 생략한다.5 and 6 are views showing a refrigerator according to an embodiment of the present invention, the same configuration and the same reference numerals are denoted with the same configuration as the conventional configuration, and detailed description thereof will be omitted.
도면에서 참조부호(10)은 외상판(1b)과 소정의 간격을 두고 형성된 내상판을 나타내고 있으며, 상기 내상판(10)의 내부상측에는 내측으로 돌출되는 계단부(11)가 형성되어 있고, 상기 계단부(11)의 상측에는 경사부(12)가 연장형성되어 있다.In the drawing, reference numeral 10 denotes an inner plate formed at predetermined intervals from the outer plate 1b, and a stepped portion 11 protruding inward is formed on the inner upper side of the inner plate 10. An inclined portion 12 is formed on the upper side of the step portion 11.
도면에서 미설명부호 13은 압축기(4), 응축기(5) 및 증발기(6)로 냉매가 순환되도록 하는 소정의 직경을 갖는 금속 또는 수지제의 냉매관을 나타내고 있다.In the drawing, reference numeral 13 denotes a metal or resin refrigerant tube having a predetermined diameter to allow refrigerant to be circulated to the compressor 4, the condenser 5 and the evaporator 6.
다음에 이와같이 구성된 본 고안에 따른 냉장고용 내상판구조의 작용 및 효과를 설명한다.Next will be described the operation and effect of the inner plate structure for a refrigerator according to the present invention configured as described above.
먼저, 외상판(1a)의 내측에 소정의 간격을 두고 내상판(10)을 설치하고, 상기 내상판(10)의 내측에 지그판(J)을 설치한후 그 내측으로 폴리우레탄등의 단열재(2)를 주입한다.First, the inner plate 10 is provided at a predetermined interval inside the outer plate 1a, and the jig plate J is installed inside the inner plate 10, and then a heat insulating material such as polyurethane is disposed inside thereof.

그리고, 상기 외상판(1a)과 내상판(10)의 사이에 소정량의 단열재(2)를 주입한후 발포시키면 단열재(2)의 발포성형이 완료된다.Then, the foaming of the heat insulating material 2 is completed by injecting and foaming a predetermined amount of heat insulating material 2 between the outer plate 1a and the inner plate 10.
이때, 상기 내상판(10)에는 상측에 계단부(11)가 형성됨에 따라 제7도 및 제8도에 도시한 바와같이 상기 계단부(11)의 내측에 위치되는 지그판(J)과 내상판(10)의 접촉면적이 특히 코너부에서 종래보다 넓게 분포됨으로써 상기 내상판(10)은 단열재(2)의 팽창시 작용하는 발포압력등에도 쉽게 변형되지 않고 원래의 형상을 유지할 수 있는 것이다.At this time, as the step portion 11 is formed on the inner plate 10, as shown in Figs. 7 and 8 jig plate (J) and the inner which is located inside the step portion (11) Since the contact area of the upper plate 10 is distributed in a wider area than the conventional one, the inner upper plate 10 can maintain its original shape without being easily deformed even under the foam pressure acting upon the expansion of the heat insulating material 2.
따라서, 본 고안에 따른 냉장고용 내상판구조에 의하면, 외상판의 내측에 소정의 간격을 두고 위치되는 내상판에 내측으로 돌출되는 계단부를 형성시켜 단열재의 발포성형시 내상판과 지그판과의 접촉면적을 증대시킴으로써 단열재의 팽창시 작용하는 발포압력등에도 쉽게 변형되지 않을 뿐만 아니라 이에따라 불량율이 현저히 감소됨은 물론 생산성을 증대시킬 수 있는 등의 여러가지 이점을 갖는다.Therefore, according to the structure of the inner plate for a refrigerator according to the present invention, by forming a step portion projecting inward to the inner plate located at predetermined intervals inside the outer plate to contact the inner plate and the jig plate during the foam molding of the insulating material Increasing the area is not easily deformed even in the foam pressure acting upon the expansion of the insulation, and accordingly has a number of advantages, such as significantly reduced defect rate and increase productivity.
