Description
본 고안은 냉장고의 기계실 방열 구조에 관한 것으로, 더욱 상세하게는 냉장고의 기계실에 장착된 압축기, 응축기에서 발생된 열을 냉장고 외부로 용이하게 발산시키는 구조를 갖되 그 압축기와 응축기를 냉각하기 위해 구비된 냉각팬에 의해작업자가 상해를 입지 않는 구조를 갖는 냉장고의 기계실 방열 구조에 관한 것이다.The present invention relates to a heat dissipation structure of a machine room of a refrigerator, and more particularly, a compressor, which is mounted in a machine room of a refrigerator, has a structure for easily dissipating heat generated from a condenser to the outside of the refrigerator, and is provided to cool the compressor and the condenser. The present invention relates to a machine room heat dissipation structure of a refrigerator having a structure in which a worker is not injured by a cooling fan.
일반적으로 냉장고의 기계실은 도 1에 도시한 바와 같이, 냉각싸이클을 따라 순환하던 냉매가스는 저온저압의 상태에서 고온고압으로 변화시켜 주는 압축기(20), 열을 방출시켜 냉매가스를 액화시키는 응축기(30), 액화된 냉매가 고온고압의 상태로 증발기에 유입되지 못하도록 압력을 강하시키는 수단인 캐필라리튜브 등의 냉각싸이클 상 중요한 구성부품들이 구비되어 있고, 냉각싸이클을 따라 순환하는 냉매는 캐필라리튜브를 거친 후에 냉동실 후방에 마련되어 있는 냉각실에 설치된 증발기을 통해 증발되면서 기화되는 증발잠열로 인하여 냉장고를 냉각시키는 일련의 냉각싸이클을 반복하고 있다.In general, as shown in FIG. 1, the machine room of a refrigerator includes a compressor 20 that circulates along a cooling cycle in a state of low temperature and low pressure, and a condenser that liquefies refrigerant gas by releasing heat. 30) Important components in the cooling cycle, such as capillary tube, which is a means for lowering the pressure to prevent the liquefied refrigerant from flowing into the evaporator at a high temperature and high pressure, are provided, and the refrigerant circulating along the cooling cycle is capillary. After passing through the tube, a series of cooling cycles are repeated to cool the refrigerator due to the latent vaporization of evaporation as it evaporates through an evaporator installed in a cooling chamber located behind the freezing chamber.
이와 같이 기계실(10)에 설치된 냉각싸이클상의 주요 구성부품들을 따라 냉매가 순환되는 과정에서, 증발기에서 기화되면서 저온저압의 기체상태로 상변화를 일으킨 냉매가스는 흡입 파이프를 통해 압축기(20)로 유입되면서 고온고압으로 변화될 때에 압축기(20) 작동시 약 90 ∼ 100 ℃ 정도의 고열이 발생하며, 아울러 응축기(30)에서 방열된 약 40 ∼ 50 ℃의 열 등에 의해 기계실(10) 내부는 상당한 고온상태로 유지되기 때문에 압축기(20)의 운전효율이 저하되어 전반적인냉장고의 냉각성능이 열화되는 문제를 방지코자 기계실(10) 내부의 일측에 냉각팬(40)을 설치하여 압축기(20) 및 응축기(30)를 냉각시키고 있었다.As the refrigerant is circulated along the major components on the cooling cycle installed in the machine room 10, the refrigerant gas vaporized in the evaporator and caused a phase change to a low-temperature low-pressure gas state flows into the compressor 20 through the suction pipe. When the compressor 20 is operated at a high temperature and high pressure, high heat of about 90 to 100 ° C. is generated, and at a high temperature of about 40 to 50 ° C., which is radiated from the condenser 30, the inside of the machine room 10 is substantially hot. In order to prevent the problem that the operating efficiency of the compressor 20 is lowered and the overall cooling performance of the refrigerator is deteriorated, the cooling fan 40 is installed on one side of the inside of the machine room 10 so that the compressor 20 and the condenser ( 30) was cooled.
그런데, 상술한 종래의 기계실 방열장치는 그 일측에 설치된 냉각팬(40)에 의해 가열된 내기(內氣)가 기계실(10) 내부에서 강제순환되면서 냉각되기 때문에기계실커버(50) 양측에 천공형성된 통기공(60)을 통하여 흡입되는 외기(外氣)량이 작아 내기가 원활하게 외부로 배출되지 못하여 냉각효율이 저하되는 문제와, 이로 인하여 압축기(20)가 과열되어 열화되는 문제가 있어 왔다.However, the conventional machine room heat dissipation device described above is perforated on both sides of the machine room cover 50 because the bet heated by the cooling fan 40 installed at one side thereof is cooled while being forcedly circulated inside the machine room 10. Since the amount of outside air sucked through the air vent 60 is insufficient, the internal air cannot be discharged to the outside smoothly, and thus the cooling efficiency is lowered. As a result, the compressor 20 is overheated and deteriorated.
이러한 문제점을 해결하도록, 1997년에 출원된 실용 신안 출원 제 025475호가 개시되었다. 그러나, 상기 출원에 의하면, 응축기, 압축기 및 상기 응축기와 압축기를 냉각하기 위한 냉각팬이 각각 기계실에 내장됨으로써 냉장고 외기에 의한 응축기 및 압축기의 냉각이 원활하게 이루어지지 못하는 문제가 있고, 기계실에 장착된 기계실 커버가 제거된 경우에는 냉장고 외기의 유출입이 원할하나 냉각팬이 회전 동작 중 손상되거나 주위 물건을 손상시킬 우려가 있었다.To solve this problem, Utility Model Application 025475 filed in 1997 has been disclosed. However, according to the above application, a condenser, a compressor, and a cooling fan for cooling the condenser and the compressor are respectively installed in the machine room, thereby preventing the cooling of the condenser and the compressor by the outside air of the refrigerator smoothly. When the machine room cover is removed, the outside air of the refrigerator may be desired to flow in, but the cooling fan may be damaged during the rotation operation or the surrounding objects may be damaged.
따라서, 본 고안은 냉장고 외기가 기계실측으로 원활하게 유입됨으로써 응축기와 압축기를 용이하게 냉각시킬 수 있으며 냉각팬이 회전 동작 중 파손되거나 주위 물건을 손상시키지 않는 구조를 갖는 냉장고의 기계실 방열 구조를 제공하는 데 그 목적이 있다.Accordingly, the present invention provides a machine room heat dissipation structure of a refrigerator having a structure in which the outside air of the refrigerator is smoothly introduced into the machine room, thereby allowing the condenser and the compressor to be easily cooled, and the cooling fan is not damaged during rotational operation or damaging the surrounding objects. Its purpose is to.

이하에서는 도면을 참조하여 본 고안을 더욱 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 냉장고의 기계실 방열 구조를 도시하기 위한 개략적인 기계실의 평단면도이다.Figure 2 is a plan sectional view of a schematic machine room for showing the heat dissipation structure of the machine room of the refrigerator according to the present invention.
냉장고는 냉장실을 냉각하기 위한 냉각장치들, 예컨대 압축기(130)과 응축기(110)이 기계실(100)에 설치된다. 상기 기계실(100)은 냉장고 후측면에 제공된 외벽판(250)과, 상기 외벽판으로부터 이격하여 대면하게 배치된 내벽판(220)과, 냉장고 후부 양측면에 제공된 양측판(210, 240)에 의해 구획된 공간으로서, 내벽판(220)에 의해 저장실(300)로부터 구획되며, 양측판(240, 210)에 의해 냉장고 외부로부터 격리된다.The refrigerator includes cooling devices for cooling the refrigerating compartment, for example, the compressor 130 and the condenser 110 in the machine room 100. The machine room 100 is partitioned by an outer wall plate 250 provided on the rear side of the refrigerator, an inner wall plate 220 disposed to face away from the outer wall plate, and both side plates 210 and 240 provided on both sides of the rear side of the refrigerator. The space is partitioned from the storage compartment 300 by the inner wall plate 220 and is isolated from the outside of the refrigerator by the side plates 240 and 210.
한편, 냉매는 상기 압축기(130)에서 고온 고압으로 압축되어 응축기(110)에서 저온 고압으로 응축된다. 이때, 기계실(100)은 냉장고 외부 공기가 유입되도록 외기 유입구(200)와 상기 외기 유입구를 통해 유입된 냉장고 외기가 응축기(110)와 압축기(130)를 냉각한 후 냉장고 외부로 방출되도록 외기 유출구(205)가 제공된다.Meanwhile, the refrigerant is compressed to high temperature and high pressure in the compressor 130 and condensed to low temperature and high pressure in the condenser 110. At this time, the machine room 100 is an external air inlet 200 to cool the condenser 110 and the compressor 130 through the outside air inlet 200 and the outside air inlet so that the outside air is introduced into the refrigerator. 205 is provided.
또한, 양측판(210, 240)사이에 외벽판(250)이 배치됨으로써 상기 외벽판과 양측판이 이격한 틈으로 된 외기 유입구(200, 205)가 상기 외벽판의 양측에 각각 제공된다. 더욱이, 상기 외벽판은 외기 유입구(200)를 통해 유입된 외기를 냉각팬(120)측으로 유입시키도록 격판(215)과 차폐판(230)이 제공된다. 상기격판(215)는 상기 외기 유입구를 통해 유입된 외기를 안내하도록 외벽판의 일단부가 절곡되어 형성되어 이에 따라, 응축기(110)를 냉각한 외기는 내벽판(220)과 격판(215)사이에 제공된 틈을 통해 냉각팬(120)으로 유입된다. 또한, 상기 냉각팬(120)이 구동됨에 따라 외기가 압축기(130)로 집중하여 분출되도록 상기 냉각팬은 차폐판(230)의 통풍공(231)에 장착된다.In addition, the outer wall plate 250 is disposed between the two side plates 210 and 240, so that the outside air inlets 200 and 205 formed as gaps between the outer wall plate and the two side plates are provided at both sides of the outer wall plate, respectively. Further, the outer wall plate is provided with a diaphragm 215 and a shielding plate 230 to introduce the outside air introduced through the outside air inlet 200 to the cooling fan 120 side. The plate 215 is formed by bending one end of the outer wall plate to guide the outside air introduced through the outside air inlet, and thus, the outside air cooling the condenser 110 is disposed between the inner wall plate 220 and the diaphragm 215. It is introduced into the cooling fan 120 through the gap provided. In addition, as the cooling fan 120 is driven, the cooling fan is mounted in the ventilation hole 231 of the shielding plate 230 so that outside air is concentrated and ejected to the compressor 130.
이와 같이 냉각팬에 의해 분출된 외기는 압축기(130)를 냉각한 후 외벽판(250)과 측판(240)으로 형성된 외기 유출구(205)를 통해 냉장고 외부로 방출된다.As such, the outside air blown out by the cooling fan is cooled to the outside of the refrigerator through the outside air outlet 205 formed by the outer wall plate 250 and the side plate 240 after cooling the compressor 130.
따라서, 양측판, 외벽판, 내벽판, 차폐판, 격판은 외기를 유입시키기 위한 냉각 덕트를 형성하고, 냉각 팬(120)이 구동됨에 따라 외기는 상기 냉각 덕트를 따라 응축기를 통과하면서 상기 냉각팬으로 유입되는 것이다.Accordingly, both side plates, outer wall plates, inner wall plates, shielding plates, and diaphragms form cooling ducts for introducing outside air, and as the cooling fan 120 is driven, the outside air passes through the condenser along the cooling ducts and the cooling fan. It will flow into.
나아가, 상기 격판과 차폐판 사이에 냉각팬이 배치됨으로써 냉각팬이 구동중 이물질에 의해 파손되는 것은 방지된다.Furthermore, the cooling fan is disposed between the diaphragm and the shield plate to prevent the cooling fan from being damaged by foreign matters while driving.
상술된 바와 같이, 본 고안에 따른 냉장고 기계실의 방열 구조는 냉각팬이 구동되면 외기가 외기 입구 측판과 격판에 의해 안내되어 응축기를 냉각하면서 냉각팬으로 유입되고, 이때 냉각 팬으로 유입된 외기가 압축기를 다시 냉각하여 냉장고 외부로 방출되므로 압축기와 응축기가 동시에 냉각되고, 나아가 응축기와 압축기는 냉장고 외기에 노출되게 설치됨으로써 열교환이 원활하게 수행됨은 물론 냉각팬이 외벽판에 의해 둘러싸여 있어서 냉각팬이 파손되는 것을 방지할 수 있다.As described above, in the heat dissipation structure of the refrigerator machine room according to the present invention, when the cooling fan is driven, outside air is guided by the outside air inlet side plate and diaphragm to cool the condenser, and the air is introduced into the cooling fan. After cooling again to the outside of the refrigerator, the compressor and the condenser are cooled at the same time, and furthermore, the condenser and the compressor are exposed to the outside of the refrigerator, so that the heat exchange is smoothly performed, and the cooling fan is surrounded by the outer wall plate, which causes the cooling fan to be damaged. Can be prevented.
