본 발명은 직냉식 냉장고의 증발장치에 관한 것으로, 특히 조립 및 제작성을 향상시킬 수 있는 직냉식 냉장고의 증발장치에 관한 것이다.The present invention relates to an evaporation apparatus for a direct-cooling refrigerator, and more particularly to an evaporation apparatus for a direct-cooling refrigerator that can improve assembly and manufacturability.
직냉식 냉장고로써는 냉동·냉장 각 저장실내의 주벽면에 증발기를 직접 설치하고, 그의 증발기에 실내측 공기가 직접 접촉되면서 열교환을 이루어 저장실내를 소기의 저장온도로 유지케하고 있다. 그러한 직냉식 냉장고는 일반적으로 저장실의 저장공간 확보 또는 외관성을 고려하여 저장실의 주벽면을 이루는 내상과 단열층의 사이에 매몰되어 설치되는데, 이렇게 증발기가 내상에 파묻혀 설치되는 것에 의하여 내상과 증발기의 전열면적 제공에 많은 연구와 노력을 기울여 왔다.As a direct-cooling refrigerator, an evaporator is directly installed on the main wall surface of each of the freezing and refrigerating storage chambers, and the inside air is directly contacted with the evaporator to heat exchange to maintain the storage chamber at a desired storage temperature. Such a direct-cooling refrigerator is generally installed buried between an inner layer and an insulation layer forming the main wall surface of the storage compartment in consideration of securing the storage space or appearance of the storage compartment. Much research and effort has been put into providing.
이러한 내상은 일반적으로 제조비용을 줄이기 위해 간단한 진공 성형사출공정에 의해 제되고 있는데, 이 제조과정에서는 구조개발에 제한이 따르고, 그러한 구조제한으로 단순한 구조에서만 제조가 가능한 것이다.Such internal wounds are generally limited by a simple vacuum injection molding process in order to reduce manufacturing costs. In this manufacturing process, there is a limitation in the development of the structure, and only such a structure can be manufactured in a simple structure.
그 일례를 들어 보면 통상 제4도에서와 같이 저장실 중심측으로 돌출되는 반원호형상의 돌출부(110)을 적절한 가격으로 배열하고, 이의 각 돌출부 사이사이에 면적부(120)를 구비하고 있다. 그리고 상기 각 돌출부(110)의 이면에는 증발기(200)가 삽입·이탈 가능하도록 일방이 개방되고, 증발기의 형태를 따라 구성되는 반원호형상이 수용홈(111)이 제공된다. 이렇게 제조된 내상(100)의 수용홈(111)에 증발기(200)를 넣고 그 내상의 이면상에 열전도성이 우수한 알루미늄재로 구성되는 열전도판지(300)를 전면적으로 도포하여 소기목적을 달성케하고 있다. 즉 내상에 증발기의 전열면적을 증대하여 증발효율을 높힘과 아울러, 증발기가 수용홈 내주벽에 밀접되게 하고 수용홈으로 부터 이탈되는 것을 방지하는 유지력을 제공하게 된다. 그런데 이렇게 내상의 이면에 구비되는 수용홈의 내에 증발기를 조립하는 작업이 용이하지 못한, 다시 설명하면 파이프를 적정한 길이내에서 좌·우단을 교대적이고 연속적으로 절곡하여 하나의 몸체로 구성되는 증발기의 형태에 맞추어 내상의 이면에 수용홈을 동형으로 구비하고, 이러한 수용홈내에 증발기를 끼워넣어 조립시키고 있는데, 증발기의 밴딩공정에서 규격이 다소 변화되거나 운반 또는 작업과정에서 다소 비틀리어 증발기의 수평도가 유지되지 않은 상태에서 조립시, 증발기자체의 탄발력에 의해 수용홈으로 부터 튀쳐나오려 하여 이를 별도로 잡아주어야 하거나, 별도의 과정장치를 이용하여 잡아주며 열전도판지의 접착작업을 수행하고 있다.For example, as shown in FIG. 4, a semicircular arc-shaped protrusion 110 projecting toward the center of the storage compartment is arranged at an appropriate price, and an area portion 120 is provided between the protrusions. In addition, one side of the protrusions 110 may be opened on the rear surface of each of the protrusions 110 so that the evaporator 200 may be inserted and separated, and a semi-circular arc shape accommodating the shape of the evaporator is provided with the receiving groove 111. The evaporator 200 is placed in the receiving groove 111 of the inner phase 100 manufactured as described above, and the thermal conductive cardboard 300 made of aluminum material having excellent thermal conductivity is applied to the entire surface of the inner phase 100 to achieve a desired purpose. Doing. That is to increase the heat transfer area of the evaporator in the inner phase to increase the evaporation efficiency, and to provide a holding force to close the evaporator to the inner circumferential wall of the receiving groove and to prevent the evaporator from being separated from the receiving groove. By the way, it is not easy to assemble the evaporator in the receiving groove provided on the back of the inner box, that is, the shape of the evaporator composed of one body by bending the left and right ends alternately and continuously in a proper length. The receiving groove is provided on the back of the inner box in the same shape, and the evaporator is inserted into the receiving groove to assemble. The specification is somewhat changed in the bending process of the evaporator, or the level of the twisted evaporator is maintained somewhat during transportation or operation. When it is not assembled, it is necessary to catch it separately by trying to pop out of the receiving groove by the elasticity of the evaporator itself, or by using a separate process device, and is carrying out the bonding work of the thermal conductive cardboard.
따라서 조립성이 좋지 않고 생산능률을 떨어뜨리고 있는 것이다. 또 그렇게 비틀어져 수평도가 유지되지 않은 부분은 수용홈으로 부터 튀쳐나오려는 힘이 계속 가해져, 그 부분의 열전도판지 접합력을 약화시키고 증발기가 수용홈의 주벽면으로 부터 들뜨게 되어 전열을 떨어뜨리고 냉장성능에 영향을 끼치게 된다.Therefore, assembly is not good and production efficiency is falling. In addition, the part that is not leveled so as to keep the level is continuously applied, and the force to pop out of the receiving groove is continued to weaken the bonding force of the heat conduction board of the part, and the evaporator is lifted from the main wall of the receiving groove to reduce the heat transfer and the refrigeration performance. Will be affected.
또한, 이러한 구조에서는 증발기(200)의 무효부위가 필연적을 발생하고 있다. 더 상세하게는 증발기(200)가 반원호형상의 수용홈(111)에 끼워져 그 수용홈(111)과 약 절반정도 면접촉되고, 수용홈(111)의 개방측에서는 증발기(200)주벽면에 정점부위에서 열전도판지(300)와 부분적으로 접합되어 있다.In addition, in such a structure, an invalid portion of the evaporator 200 inevitably occurs. In more detail, the evaporator 200 is inserted into the semicircular arc-shaped receiving groove 111 and is in surface contact with the receiving groove 111 about half, and on the open side of the receiving groove 111, the vertex is formed on the main wall surface of the evaporator 200. It is partially bonded with the thermal conductive paper 300 at the site.
따라서, 수용홈(111)개방측에서 증발기(200)정접부위를 벗어난 양측부분은 내상 또는 열전도판지와 전혀 접촉되지 않고 떠있는 공간부가 제공되며, 이러한 공간부는 단열, 즉 증발기와 내상 및 열전도판지사이를 차단하는 공기층이 형성되어 그 공기층측으로 흐르는 증발기내의 냉매는 증발을 이루지 못한채 압축기측으로 회수되는 등 증발효율을 떨어뜨리고 있을 뿐만 아니라, 내장(100)의 돌출부(110)사이사이에 구비되는 면적부(120)의 전열면적에 비해 열전도판지(300)와 증발기(200)의 접합면적이 극소하여 면적부(120)의 전열량을 채 수용하지 못하고, 미쳐 증발기에서 흡열하지 못한 잔유열은 다시 실내로 방출되어 열교환효율이 떨어지고 냉장 성능이 저하되는 결함이 있다.Therefore, both sides of the evaporator 200 in the open side of the accommodating groove 111 are provided with a floating space that is not in contact with the inner or thermal conductive cardboard at all, and the space is insulated, that is, between the evaporator and the inner and thermal conductive cardboard. The air layer is formed to block the refrigerant in the evaporator flowing to the air layer side is not only to reduce the evaporation efficiency, such as being recovered to the compressor side without evaporation, the area between the protrusions 110 of the interior (100) ( Compared with the heat transfer area of 120, the bonding area between the heat conducting board 300 and the evaporator 200 is so small that the heat transfer amount of the area 120 cannot be accommodated, and the remaining heat of heat not absorbed by the evaporator is discharged back to the room. There is a defect that the heat exchange efficiency is lowered and the refrigeration performance is lowered.
본 발명은 상기와 같은 사정으로 고려하여 이루어진 것으로, 그 목적은 증발기를 미끄럼 삽입식으로 간단하고도 효과적으로 끼워맞춤 결합시킬 수 있는 직냉식 냉장고의 증발장치를 제공하는 것이다.The present invention has been made in view of the above circumstances, and an object thereof is to provide an evaporator of a direct-cooling refrigerator which can be simply and effectively fitted with an evaporator by sliding insertion.
본 발명의 다른 목적은 조리작업 및 생산성을 향상시킬 수 있는 직냉식 냉장고의 증발장치를 제공하는 것이다.Another object of the present invention is to provide an evaporation apparatus of a direct cooling refrigerator which can improve cooking operation and productivity.
본 발명의 또다른 목적은 증발기의 무효부위를 완전 배제하고 열교환효율을 향상시킨 직냉식 냉장고의 증발장치를 제공함에 있다.It is another object of the present invention to provide an evaporator of a direct-cooling refrigerator which completely eliminates an invalid part of an evaporator and improves heat exchange efficiency.
이러한 발명의 목적은 음식물을 냉장하는, 즉 기계적인 방법으로 압축, 응축, 팽창 및 증발의 과정을 연속적으로 이루면서 소기의 열교환을 이루는 냉매를 사용하도록 된 증발장치를 제공함에 의해 달성되게 되는데, 이 증발장치는 내상에 적정간격으로 저장실측으로 튀어나오는 돌출부를 갖고있고, 이의 돌출부는 평활면상으로 구성되어 증발면적을 제공하고, 돌출부 사이사이에는 면적부를 일체로 구비하고 있다.The object of this invention is achieved by providing an evaporator which refrigeration of food, ie using a refrigerant which achieves a desired heat exchange while successively compressing, condensing, expanding and evaporating in a mechanical manner. The apparatus has protrusions protruding to the storage compartment at appropriate intervals in the inner phase, and the protrusions are formed on a smooth surface to provide an evaporation area, and have an integral area between the protrusions.
돌출부이면 양측에는 또한 그 내상이면상에 돌출부와는 상반되는 방향으로 연장하여 걸림턱을 일체로 구성하고 이의 걸림턱과 돌출부이면 사이에 증발기가 미끄럼식으로 끼워맞춤 결합되는 열호형상의 수용부를 구비하고 있다. 따라서 증발기를 용이하고도 견고히 조립하고 전열면적을 증대시키게 된다.If it is a protrusion, both sides also extends in a direction opposite to that of the protrusion on the inner surface of the hook to form a locking jaw integrally, and has a recessed arc-shaped receiving portion in which the evaporator is slidably fitted between the locking jaw and the protrusion. have. Therefore, the evaporator can be easily and firmly assembled and the heat transfer area is increased.
다음 본 발명의 실시예를 도면에 의거하여 구체적으로 설명하겠다. 제1도는 본 발명에 따른 증발구조가 설치되는 냉장고가 도시되어 있는데, 이 냉장고는 냉장실(10)과 냉동실(20)을 분리벽(30)으로 하여 상하측에 격리 구성하고 있다.Next, embodiments of the present invention will be described in detail with reference to the drawings. 1 shows a refrigerator in which an evaporation structure is installed according to the present invention, and the refrigerator is separated from the upper and lower sides by using the refrigerating chamber 10 and the freezing chamber 20 as the separating walls 30.
각 냉장·냉동실(10), (20)은 별도의 증발기(200)를 갖고 있으며, 이러한 증발기(200)는 실의주벽을 이루는 내상(100)에 감싸여 냉장고 주벽내에 파묻혀 설치될 것이다.Each refrigeration and freezing chamber (10), 20 has a separate evaporator 200, this evaporator 200 will be installed in the inner wall of the refrigerator immersed in the inner wall of the refrigerator forming the main wall of the chamber.
이렇게 파묻혀 설치되는 증발기(200)는 실내공기와는 직접 접촉되지 못하고 내상을 통해 간접적인 열교환을 이루게 된다. 상기 냉장고는 본 발명의 증발장치가 설치될 수 있는 냉장기구의 일실시예이다.The buried evaporator 200 is thus not in direct contact with the indoor air and indirect heat exchange through the inner phase. The refrigerator is one embodiment of a refrigeration apparatus in which the evaporator of the present invention can be installed.
제2도 및 제3도는 증발장치에 관해 상세히 도시되어 있다. 즉, 내상(100)에 적정간격으로 돌출부(110)을 구비하고, 이 돌출부(110)의 이면에 증발기(200)을 설치하고 있다. 돌출부(110)는 내상에서 저장실측으로 튀어나아가 설치되는데, 이때 그 돌출부의 높이는 증발기(200)의 지름보다 낮은 높이를 가지고 있다.2 and 3 show details of the evaporator. That is, the inner part 100 is provided with the protrusion part 110 at appropriate intervals, and the evaporator 200 is provided in the back surface of this protrusion part 110. As shown in FIG. Protruding portion 110 is installed to protrude from the inner side to the storage compartment, wherein the height of the protrusion has a height lower than the diameter of the evaporator (200).
이러한 돌출부(110)는 평활면상으로 구성되어 증발면적을 제공하게 될 것이다.This protrusion 110 will be configured on a smooth surface to provide an evaporation area.
그리고 돌출부(110)의 사이사이에는 면적부(120)를 구비하고있다. 또 상기 돌출부(110)이면 양측에는 그 내상(100)이면상에 돌출부(110)와는 상반되는 방향에 일체로 연장하여 돌출부(110)양단과 동일한 반경을 갖는 원호상의 걸림턱(130)을 구비함과 아울러, 이 걸림턱(130)과 돌출부(110)양단의 사이에 증발기(200)가 미끄럼방식으로 끼워맞춤 결합되는 열호형상의 수용공간을 제공한다.The area 120 is provided between the protrusions 110. In addition, both sides of the protruding portion 110 have an arc-shaped locking jaw 130 having the same radius as both ends of the protruding portion 110 by integrally extending in a direction opposite to the protruding portion 110 on its inner surface 100. In addition, there is provided an accommodating space in which the evaporator 200 is fitted in a sliding manner between the engaging jaw 130 and the both ends of the protrusion 110.
이때 걸림턱(130)는 증발기의 외경보다 다소 적은 반경을 가지는 원호로 구성되고, 자체에 탄성력을 보유하여 증발기(200)가 유동되지 않도록 하는 유지력을 가지고 있다. 이러한 걸림턱(130)은 내상(100)의 이면적당장소에 설치되어 증발기의 끼움을 수용하게 되는데, 더 상세하게는 내상은 제1도에서와 같이 수직면(101)과, 그 수직면(10)상하단에 한쌍의 수평면(102), (103)을 평행하게 일체로 구성시키고, 이의 내상 상하측 수평면(102), (103)이면상에 제2도에서와 같이 적당한 길이내에 설치되는 걸림턱(130)의 내에 ㄷ자형상으로 구성된 증발기(200)를 내상의 수직면(101)후방에서 미끄럼식으로 끼워맞춤 결합되게 하여 조립을 이룬다.At this time, the locking step 130 is composed of a circular arc having a radius slightly smaller than the outer diameter of the evaporator, and has a retaining force to prevent the evaporator 200 from flowing by having an elastic force in itself. The locking jaw 130 is installed at a place per back surface of the inner box 100 to accommodate the fitting of the evaporator. More specifically, the inner box has a vertical surface 101 and upper and lower ends of the vertical surface 10 as shown in FIG. A pair of horizontal surfaces 102 and 103 are integrally formed in parallel to each other, and the locking jaw 130 is installed in an appropriate length on the inner surface of the upper and lower horizontal surfaces 102 and 103 of the upper surface as shown in FIG. An evaporator 200 having a U-shape in the interior is assembled by slidingly fitting in the rear of the vertical surface 101 of the inner box.
이러한 내상(100)은 적합한 사출성형공정을 통해 제조될 것이다. 그리고 내상의 이면에서 제공되는 수용부는 증발기의 일부주벽만을 수용한다.This inner bed 100 will be manufactured through a suitable injection molding process. And the receiving portion provided on the back of the inner phase receives only a part of the peripheral wall of the evaporator.
즉, 증발기 전체 외주면에서 약 절반정도의 주면을 수용하게 되고 수용부(140)이외 타측에는 증발기(200)가 노출되도록 개방되고 있고, 이러한 개방측으로 노출되는 증발기(200)의 타주벽면은 열전도판지(300)가 직접 접합될 수 있는 접합면으로 제공될 것이다. 그러면, 제2도 및 제3도를 참조하여 증발장치의 작용효과에 관해 설명하겠다.That is, about half of the main surface is accommodated on the entire outer circumferential surface of the evaporator, and the other side of the evaporator is opened to expose the evaporator 200 on the other side, and the other circumferential wall surface of the evaporator 200 exposed to the open side is made of thermal conductive cardboard ( 300 will be provided as a joining surface that can be joined directly. Next, the working effects of the evaporator will be described with reference to FIGS. 2 and 3.
내상(100)의 돌출부(110) 양단부에 구비되는 걸림턱(130)을 이용하여 증발기(200)을 내상이면에 미끄럼식 끼워맞춤으로 결합되게 하므로써, 증발기가 내상이면에 간편하고도 견고히 조립되고, 따라서 종래 조립작업시 증발기가 내상으로 수용홈으로 부터 증발기가 이탈하려 하여 별도로 잡아주거나 가조립하는등 조립작업에 번거러움을 배제하고 열전도판지(300)의 접착작업을 간단히 이루어 조립성은 물론 생산성을 향상시키게되는 효과가 있다.By using the locking projections 130 provided at both ends of the protrusions 110 of the inner box 100, the evaporator 200 is coupled to the inner surface by sliding fitting, so that the evaporator is easily and firmly assembled to the inner surface of the inner box. Therefore, the conventional assembling work to remove the hassle in the assembly work, such as holding the evaporator separate from the receiving groove from the receiving groove to the inner phase to eliminate the hassle in the assembly work and to simplify the bonding work of the heat conducting cardboard 300 to improve the assembly and productivity It works.
그리고 그 걸림턱의 지탱력으로 증발기를 내상이면에 밀접시키어 전열성이 우수할 뿐만 아니라, 열전도판지의 접합력이 약화되어 내상이면에서 떨어져도 증발기를 수용부에서 이탈시키지 않고 유지케하므로 제품성 및 신뢰성이 우수한 효과가 있다.In addition, the holding force of the locking jaw closes the evaporator to the inner surface of the inner plate to provide excellent heat transfer properties. Also, the bonding force of the thermal conductive paper is weakened, so that the evaporator can be maintained without detaching from the receiving part even if the inner surface of the inner sheet is separated. Excellent effect.
또한, 증발기(200)에서 걸림턱(130)에 끼워지는, 그 이외주벽에 미접합 부분없이 열전도판지(300)가 전면적으로 접합되어 증발기를 무효히 버려지는 부분없이 전면적으로 증발을 이루게 하므로써 증발효율을 높이고, 더나아가서 증발이 완전하여 냉각싸이클의 구동이 원활하고 압축기에 무리를 줄이어 가동성은 물론 소비전력을 줄이는 경제적인 이점도 있다.In addition, the evaporation efficiency by evaporating the entire surface of the evaporator 200 without the portion of the heat conduction cardboard 300, which is fitted to the locking step 130, the other circumferential wall without the non-bonded portion is completely bonded to the evaporator is discarded. In addition, there is an economical advantage that the cooling cycle can be smoothly driven and the compressor can be reduced and the power consumption is reduced by further improving the evaporation.
그리고, 증발기(200)를 양측으로 등분하여 걸림턱(130)측에서는 면적부(120)로부터 전열되는 열을 흡열하고, 걸림턱이외의 개방측에서는 돌출부(110)으로 부터 전열되는 열을 흡여케 하므로써, 열교환성능이 더욱 우수하고도 신속한 효과가 있고, 더 구체적으로 설명하면 돌출부(110)의 너비는 증발기 외경절반의 외주변 길이 2배보다 다소 적은 길이를 가지고 있게 하므로 돌출부측에 전열된 열을 인접한 증발기와 동시적이고 분배적으로 흡열하고, 이렇게 흡열된 열은 증발기에서 충분한 전열면적을 제공하여 열손실없이 열교환을 이루게 된다.Then, by dividing the evaporator 200 to both sides by absorbing the heat transferred from the area portion 120 on the locking step 130 side, by absorbing the heat transferred from the protrusion 110 on the open side other than the locking step, The heat exchange performance is excellent and has a quick effect, and more specifically, the width of the protrusion 110 has a length less than twice the outer periphery of the evaporator outer diameter, so that the heat transferred to the protrusion side is adjacent to the evaporator. And endothermic to endothermic, and the endothermic heat provides sufficient heat transfer area in the evaporator to achieve heat exchange without heat loss.
또 이러한 증발구조는 그 증발기의 설치간격을 다소 넓게 가지고 있어 증발기의 제조비용을 줄이게 되는 이점이 있었을 뿐 아니라, 증발기 설치면적을 넓히고 실내의 전체 온도대를 고루 유지하여 공조성은 물론 저장성을 향상시키게 되는 이점이 있다.In addition, this evaporation structure has the advantage of reducing the installation cost of the evaporator because the evaporator has a somewhat wider spacing, and also improves the air-conditioning and storage properties by increasing the evaporator installation area and maintaining the entire temperature range in the room. There is an advantage.
