본 발명은 냉장고에 관한 것으로, 특히 냉장고의 닥트구조에 관한 것이다.The present invention relates to a refrigerator, and more particularly to a duct structure of the refrigerator.
종래의 냉장고는 제2도에 도시한 바와 같이, 주응축기(10), 결로방지파이프(11) 및 보조응축기(12)로 구성되어 있다. 이때, 주응축기(10)는 냉장고(1)의 후레임 뒷판(13)이나 캐비넷트(14)의 좌우측 전면적에 걸쳐서 지그재그 형상으로 배치된 후, 알루미늄테이프의 부착에 의해 단열부재(15)의 측벽에 설치되어 왔었다.A conventional refrigerator is composed of a main condenser 10, a condensation prevention pipe 11 and an auxiliary condenser 12, as shown in FIG. At this time, the main condenser 10 is arranged in a zigzag shape over the right and left front surface of the frame back plate 13 or the cabinet 14 of the refrigerator 1, and then attached to the side wall of the heat insulating member 15 by attaching aluminum tape. It has been installed.
한편, 상기 결로방지 파이프(11)는 이슬맺힘을 방지하도록 냉장고(1)의 전면의 후렌지 외주면에 매설되어 왔었다.On the other hand, the condensation preventing pipe 11 has been buried in the outer peripheral surface of the flange of the front of the refrigerator 1 to prevent dew condensation.
그리고, 상기 보조응축기(12)는 한 곳에 모여진 제상수를 증발시키도록 증발접시(16)의 하단에 설치되어 왔었다.In addition, the auxiliary condenser 12 has been installed at the lower end of the evaporation plate 16 to evaporate the defrost water collected in one place.
이와 같이 구성된 응축장치는 냉장고(1)의 하단에 장착된 압축기(17)가 고내에 설정된 온도에 도달하기 위하여 작동을 시작하면, 고온고압의 기채냉매는 보조응축기(12)와 주응축기(10), 결로방지파이프(11)를 순차적으로 통과하면서 실온고압으로 변환되어 액화되고, 모세관을 통해 감압되어 증발기(19)를 통과하면서 팽창함으로써 냉각되어 진다.The condenser configured as described above operates when the compressor 17 mounted on the lower end of the refrigerator 1 starts to reach a temperature set in the refrigerator, and the high-temperature and high-pressure gas refrigerant is the auxiliary condenser 12 and the main condenser 10. In order to pass through the condensation prevention pipe (11) in order to be converted to a high temperature room pressure and liquefied, it is cooled by expanding through the evaporator (19) under reduced pressure through a capillary tube.
그리고 냉각된 냉매는 증발기(19)의 일측면에 장착된 모터(20)의 구동에 의한 송풍팬(21)의 회전력에 댐퍼부재(22)의 안내를 받아 분배되어 냉동실(23)과 냉장실(24)로 각각 토출되어 진다.The cooled refrigerant is distributed under the guidance of the damper member 22 to the rotational force of the blower fan 21 driven by the motor 20 mounted on one side of the evaporator 19 to distribute the freezer compartment 23 and the refrigerating compartment 24. Are each discharged.
제2도 내지 제4도에 도시한 바와 같이, 냉장고(1)의 하단 후측에 형성된 기계실(30)과, 상기 기계실(30)내에 일측에 장착되어 냉매를 고온 고압의 기체로 압축시키는 압축기(17)와, 상기 기계실(30) 내에 고정수단(40)을 매개로 장착되어 응축열을 이용하기 위한 주응축기(50)와 상기 주응축기의 일측에 상기 고정수단(40)을 매개로 지지고정되어 주응축기(50)와 압축기를 냉각시키도록 전원을 인가받아 작동되는 냉각수단(60)과, 상기 기계실(30)내에 외부공기가 유입 및 배출되도록 덮어주는 카바부재(70)로 이루어져 있다.As shown in FIGS. 2 to 4, the machine chamber 30 formed at the lower rear side of the refrigerator 1 and the compressor 17 mounted on one side in the machine chamber 30 to compress the refrigerant into gas of high temperature and high pressure. And the main condenser 50 mounted on the machine room 30 via the fixing means 40 to support the condensation heat and the one side of the main condenser by the fixing means 40. 50 and a cooling means 60 which is operated by being supplied with power to cool the compressor, and a cover member 70 which covers the outside air to be introduced into and discharged from the machine room 30.
이러한 구성의 냉장고의 작동을 살펴보면, 냉장고(1)의 냉동실(23)과 냉장실(24)의 고내가 소정의 설정온도에 도달하기 위하여 메인스위치(도시안됨)를 작동시키면, 압축기(17)와 동시에 냉각수단(60)이 작동하게 된다.Referring to the operation of the refrigerator having such a configuration, when the inside of the freezer compartment 23 and the refrigerating compartment 24 of the refrigerator 1 operates the main switch (not shown) to reach a predetermined set temperature, simultaneously with the compressor 17 Cooling means 60 is activated.
즉, 압축기(17)가 작동하게 되면, 압축기(17)의 압축작용에 의해 고온고압의 기체냉매 가스가 토출되어 보조응축기(12)를 통과하여 환상용 주응축기(50)의 내부를 흐르면서 크게 냉각되고, 순차적으로 결로방지파이프(11)를 거쳐서 냉장고의 주위온도인 실온보다 약 6℃ 내지 13℃ 정도인 다소높은 온도와 고압액체 냉매로 상변화되어 모세관(18)을 통과함으로써 감압된다.That is, when the compressor 17 is operated, the gas refrigerant gas having a high temperature and high pressure is discharged by the compression action of the compressor 17 and passes through the auxiliary condenser 12 to flow largely inside the annular main condenser 50. Subsequently, through the condensation prevention pipe 11, the phase change to a somewhat higher temperature and a high-pressure liquid refrigerant, which is about 6 ° C to 13 ° C than the ambient temperature of the refrigerator, is reduced in pressure by passing through the capillary tube 18.
이때, 액체냉매는 증발기(19)로 유입되어 팽창됨으로써 저온저압으로 기화됨과 동시에 증발하여 냉각작용을 행하게 되는 것으로, 이상과 같이 통상적인 냉장고(1)의 냉동사이클에 따라 일정시간 동안 운전이 이뤼어지면 고내는 소정의 온도로 냉각되는 것이다.At this time, the liquid refrigerant is introduced into the evaporator 19 and expanded to evaporate at a low temperature and low pressure and to evaporate to perform a cooling action. As described above, operation is performed for a predetermined time according to a conventional refrigeration cycle of the refrigerator 1. The ground chamber is cooled to a predetermined temperature.
제5도에 도시된 냉장고 덕트를 설명하면, 가이드(100)와 후면단열벽 사이의 증발기(19)에서 발생된 냉기는 단순히 팬모터(21)에 의해 저장실로 공급된다. 그러나, 이러한 종래의 기술은 냉장실의 팬이 오프시 증발기에 남아 있는 냉기가 자연대류에 의하여 고내로 유입되어 냉장실의 하부에 과냉(過冷)이 발생하는 문제점이 있었다.Referring to the refrigerator duct shown in FIG. 5, the cold air generated in the evaporator 19 between the guide 100 and the rear insulation wall is simply supplied to the storage compartment by the fan motor 21. However, this conventional technology has a problem that the cold air remaining in the evaporator when the fan of the refrigerating compartment is off flows into the refrigerator by natural convection, so that subcooling occurs in the lower part of the refrigerating compartment.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 냉장실의 팬 오프시 증발기에 남아 있는 냉기가 자연대류에 의해 고내로 유입되어 과냉현상이 발생되는 문제점을 해결하기 위한 것이다.The present invention is to solve this problem, to solve the problem that the cold air remaining in the evaporator during the fan-off of the refrigerating chamber flows into the interior by the natural convection to cause the supercooling phenomenon.
이러한 목적을 달성하기 위한 본 발명에 따른 냉장고 덕트구조는, 전면이 개방된 본체, 도아, 냉기를 발생시키는 증발기, 상기 증발기를 덮고 냉기유입구가 형성된 커바와, 송풍팬으로 구성된 냉장공에 있어서, 냉기가 유입되는 증발기의 상기 냉기유입구의 위치를 증발기의 하부면보다 높은 위치에 설치한 것을 특징으로 한다.Refrigerator duct structure according to the present invention for achieving the above object, the front body is open, the evaporator for generating a cold air, the cold air inlet consisting of a cover covered with the evaporator and a cold air inlet, blower fan, cold air Characterized in that the position of the cold air inlet of the evaporator is introduced into a position higher than the lower surface of the evaporator.
이하에서는 본 발명의 실시예를 첨부도면을 참조하면서 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
제1도는 본 발명의 냉장고를 도시한 것이다. 냉장실에는 증발기(104)가 수납된 카바(100)가 냉장실 배면에 설치되고, 이 카바(100)의 후면에는 가이드(101)가 설치되어, 카바(100)와 가이드(101) 사이에는 통로가 형성된다. 또한 가이드(101)는 증발기(104)의 최하단 부보다 낮은 위치까지 연장되어 설치되며, 가이드(101)의 상부는 ㄱ자로 꺽어져 고내를 순환한 냉기가 유입될 때, 증발기 상부로 흘러들어가는 것을 방지한다.1 shows a refrigerator of the present invention. In the refrigerating chamber, the cover 100 in which the evaporator 104 is stored is installed on the rear side of the refrigerating chamber, and a guide 101 is installed at the rear of the cover 100, and a passage is formed between the cover 100 and the guide 101. do. In addition, the guide 101 is installed to extend to a position lower than the lowest end of the evaporator 104, the upper portion of the guide 101 is bent by the letter A to prevent the flow into the upper evaporator when the cold air circulated in the inflow do.
동작 및 효과를 설명하면, 본 발명은 냉장실의 팬이 오프시에 증발기에 남아 있는 냉기가 자연대류에 의하여 고내로 유입되어 냉장실의 하부에 과냉이 발생하는 것을 방지할 수 있도록 냉장실 증발기의 하면을 차단하고 흡입구를 냉장실 증발기의 밑면보다 높게 설치함으로써 팬오프시 냉기가 냉장실의 하부로 빠져 나가는 것을 방지하는 트랩부가 설치되어, 냉장실 하부에 과냉이 발생하는 것을 방지할 수 있다.Referring to the operation and effect, the present invention blocks the lower surface of the refrigerating compartment evaporator so that the cold air remaining in the evaporator when the fan of the refrigerating compartment is turned off is introduced into the refrigerator by natural convection to prevent overcooling from occurring in the lower part of the refrigerating compartment. In addition, by installing the suction port higher than the bottom of the refrigerating compartment evaporator, a trap unit is provided to prevent cold air from escaping to the lower part of the refrigerating compartment during fan-off, thereby preventing overcooling from occurring in the refrigerating compartment lower portion.
