본 발명은 냉동기용 제상 시스템 장치에 관한 것으로, 구체적으로는 압축기와 응축기 사이에 설치된 축열탱크 내부를 순환하는 냉매관의 냉매열로 가온시켜 이를 증발기의 제상열원으로 하고 증발기 내부에 설치된 냉매관과 제상용 히터관이 병렬로 접촉되게 일체로 형성하여 효율적으로 제상운전이 가능한 냉동기용 제상 시스템 장치에 관한 것이다. The present invention relates to a defrosting system device for a refrigerator, and specifically, to the refrigerant heat of the refrigerant pipe circulating inside the heat storage tank installed between the compressor and the condenser, which is heated as a defrost heat source of the evaporator, and the refrigerant pipe and the defroster installed inside the evaporator.

일반적으로 냉동기라 하면 냉장고나 냉동창고와 같이 어류 육류 또는 기타 냉동식품과 같은 음식물을 보관하는 기기를 말하는데 원리는 냉매가 압축, 응축, 팽창, 증발 과정의 냉동사이클을 거쳐 순환하여 냉동기 내부에 냉기를 발생시킨다. Generally, a freezer refers to a device that stores food such as fish meat or other frozen food, such as a refrigerator or a freezer, and the principle is that refrigerant is circulated through a freezing cycle of compression, condensation, expansion, and evaporation.

이때 냉동기 내에 구비되어 냉기를 발생하는 역할을 하는 증발기의 표면에 성에가 발생하여 결빙되는데 점차 시간이 지남에 따라 결빙 면적이 커지면서 냉동효율이 저하되는 문제점이 있다.In this case, the frost is generated on the surface of the evaporator which serves to generate cold air in the freezer, and there is a problem in that the freezing efficiency decreases as the freezing area gradually increases over time.
상기와 같은 문제점으로 인해 냉동기의 원활한 냉각효과를 얻기 위해서는 지속적으로 증발기의 제상운전이 필요하다.Due to the above problems, defrosting of the evaporator is required continuously to obtain a smooth cooling effect of the freezer.
이와 관련된 선행기술로서 등록특허 10-0388720호(냉동창고용 냉동시스템의 제상장치 및 제상방법)는 도 1에 도시된 바와 같이, 증발기(20)의 상측부위에 물이 공급되는 공급부(52)로부터 분기되며, 상측방향으로 다수의 분무공(56)이 형성된 분배관(54)이 분기형성된 인렛파이프(50)와, 상기 인렛파이프(50)의 분배관(54)에 형성된 분무공(56)과 대응하게 본체(10)의 상부측에 형성되고, 양측이 외측방향으로 일정각도 경사지게 형성된 반사판(60)이 설치되어 상기 인렛파이프(50)의 분배관에 형성된 분무공(56)을 통해 분무된 물이 상기 반사판(60)에 부딪히면서 분수식으로 낙하되게 이루어진 구성이 제시되어 있다.As a related art, Patent No. 10-0388720 (Defrosting apparatus and defrosting method of a refrigeration system for a refrigerated warehouse), as shown in Figure 1, from the supply unit 52 is supplied water to the upper portion of the evaporator 20 The inlet pipe 50 is branched, the distribution pipe 54 is formed with a plurality of spray holes 56 in the upward direction and the spray hole 56 formed in the distribution pipe 54 of the inlet pipe 50 and Correspondingly formed on the upper side of the main body 10, the reflection plate 60 formed on both sides inclined at a predetermined angle in the outward direction is installed and sprayed through the spray hole 56 formed in the distribution pipe of the inlet pipe 50 A configuration made to fall in a fractional manner while hitting the reflecting plate 60 is presented.
그러나 상기 기술은 분배관(54)의 상측방향으로 형성된 분무공(56)을 통해 물이 분사되어 상부에 구비된 반사판(60)에 부딪히면서 하측방향의 증발기(20)로 분무 되는 과정에 있어서, 분배관(54)의 분무공(56)에 물이 다시 떨어져 형성된 물방울이 냉동이 가동되면서 그 부분이 얼게 되고 이 때문에 분무공(56)이 막혀 원활한 분무작용에 차질이 생기는 문제점이 있다.However, in the above technique, the water is sprayed through the spray hole 56 formed in the upper direction of the distribution pipe 54 to impinge on the reflecting plate 60 provided on the upper side, and sprayed into the lower evaporator 20 in the process of Water droplets formed in the spray hole 56 of the pipe 54 again is frozen, the portion of the water is frozen as the freezing is operated, and this causes the spray hole 56 to be blocked, resulting in a smooth spraying operation.
뿐만 아니라 반사판(60)에 부딪혀 하측 방향으로 분배관(54)을 지나서 증발기(20)로 분무 되기 때문에 분배관(54)이 차지하는 면적부분은 가려져 증발기(20) 전체에 골고루 분무 될 수 없고 이에 따른 제상효과가 저하되는 문제점이 있다.In addition, since it hits the reflecting plate 60 and is sprayed to the evaporator 20 through the distribution pipe 54 in the downward direction, the area portion occupied by the distribution pipe 54 is covered and cannot be evenly sprayed all over the evaporator 20. There is a problem that the defrosting effect is lowered.
또 다른 선행기술로서 공개특허 1995-0003760호(냉장고의 제상장치)는 도 2에서 도시된 바와 같이, 압축기(1)에서 발생되는 고온을 축열시키도록 소정물질을 저장하여 압축기(1)에 밀착 설치된 축열용기(7)와, 상기 축열용기(7) 내부를 선회하고, 증발기(5)를 소정형태로 감싸도록 하되, 상기 축열용기(7)와 증발기(5) 사이에 열교환이 가능하도록 폐회로로 구성한 제상용 냉매관(9)과, 상기 제상용 냉매관(9)의 소정부위에 설치되어 냉매의 흐름을 강제 구동시키는 순환펌프(10)로 이루어진 구성이 제시되어 있다. As another prior art, Korean Patent Publication No. 1995-0003760 (a defroster of a refrigerator) is installed in close contact with a compressor 1 by storing a predetermined material to accumulate high temperature generated in the compressor 1, as shown in FIG.

상기 기술은 축열용기(7)가 압축기(1)와 밀착하여 설치되는데 압축기(1)에서 발생되는 상당량의 진동에 의해 밀착설치된 축열용기(7)에 진동이 그대로 전달되어 축열용기(7)가 파손될 우려가 있고, 이에 따른 축열용기(7)의 교체 또는 유지비용문제와 내부물질이 누설되는 문제점이 있다.According to the above technique, the heat storage container 7 is installed in close contact with the compressor 1, and the vibration is transferred to the heat storage container 7 installed in close contact with the vibration generated in the compressor 1 so that the heat storage container 7 may be damaged. There is a concern, and thus there is a problem of replacement or maintenance cost of the heat storage container 7 and leakage of internal materials.
또한 상기 기술은 제상용 냉매관(9)이 증발기(5)의 외부만 감싸는 형태의 구조로서 내부까지 열이 제대로 전달되지 않기 때문에 열 효율이 저하될 뿐만 아니라 제상 효과에 비해 냉장고 내부온도가 상승하는 문제점이 있고, 이 때문에 원활한 제상효과를 얻기 위해서는 별도로 핫 가스 또는 물 분사장치를 구비해야 하는 문제점이 있다.In addition, the above-described technology is a structure in which the defrost refrigerant tube 9 only covers the outside of the evaporator 5, and since heat is not properly transferred to the inside, the thermal efficiency is lowered and the temperature inside the refrigerator is increased compared to the defrost effect. There is a problem, and therefore, in order to obtain a smooth defrosting effect, there is a problem in that a separate hot gas or water injector is provided.

본 발명의 축열탱크(250)는 압축기(100)를 거친 고온고압의 기체상태 냉매의 열을 회수하고 축열 하기 위한 구성으로써 내부에는 냉매관(1)과 제상용 히터관(2)의 열교환이 원활히 이루어지도록 축열물질이 채워지는데 이 축열물질은 상변화물질(PCM)로 구비되어 사용된다.The heat storage tank 250 of the present invention is configured to recover the heat of the high-temperature, high-pressure gaseous refrigerant passing through the compressor 100 and to accumulate heat, and the heat exchange between the refrigerant pipe 1 and the defrost heater tube 2 is performed smoothly. The heat storage material is filled to make the heat storage material, which is used as a phase change material (PCM).
상기 상변화물질(Phase Change material)은 공지된 것으로, 상변화과정을 통하여 많은 양의 열에너지를 축적하거나 저장된 열에너지를 방출하며, 일정온도에 따라 액체에서 고체, 고체에서 액체로 변하면서 잠열(열을 저장)하거나 방열(열을 방출)하는 축열 물질을 의미한다.The phase change material is known and accumulates a large amount of thermal energy or emits stored thermal energy through a phase change process, and changes latent heat (heat from heat to liquid, solid to liquid, depending on a predetermined temperature). Heat storage material that stores or radiates heat.
본 발명의 축열탱크(250)는 압축기(100)를 거친 냉매열을 축열하기 위한 구성으로써 압축기(100)와 응축기(200) 사이에 설치되는 구성이지만 도 3에 도시한 바와 같이 압축기(100)와는 이격 설치되고 응축기(200)와 근접되도록 설치한다. The heat storage tank 250 of the present invention is configured to accumulate the refrigerant heat passing through the compressor 100 and is installed between the compressor 100 and the condenser 200, but as shown in FIG. 3, the heat storage tank 250 is different from the compressor 100. Installed to be spaced apart and close to the condenser 200.
상기 축열탱크(250)는 내부에 선회되게 설치된 냉매관(1)의 냉매열로만 축열이 가능하지만 응축기(200)의 일측에 설치된 송풍팬(210)의 송풍유입방향 전방에 응축기(200)를 설치하고 후방에 축열탱크(250)를 구비함으로써, 상기 송풍팬(210)에 의해 외부로 방출되는 열이 축열탱크(250) 표면을 한번더 가열하여 축열효과를 높일 수 있다.The heat storage tank 250 may be regenerated only by the heat of the coolant of the coolant pipe 1 installed to be pivoted therein, but the condenser 200 is installed in the air inlet flow direction of the blower fan 210 installed at one side of the condenser 200. And by providing a heat storage tank 250 in the rear, the heat released to the outside by the blowing fan 210 can heat the surface of the heat storage tank 250 once more to increase the heat storage effect.
