냉동·냉장용 압축기의 배관연결장치{Piping coupling device for freeze and refrigeration compressor}Piping coupling device for freeze and refrigeration compressor

본 고안은 냉동ㆍ냉장용 압축기의 배관연결장치에 관한 것으로, 더욱 상세하게는 압축기 내부에 구비된 관연결부를 일중강관 또는 이중강관으로 대체하고 압축기 외부로 돌출되는 관연결부만 동관을 사용함으로써 관연결부에 사용되는 동재료를 절감하여 압축기의 생산원가를 절감할 수 있으며, 용접부위를 감소시켜 압축기의 품질을 향상시키는 냉동ㆍ냉장용 압축기의 배관연결장치에 관한 것이다.The present invention relates to a pipe connecting device of a compressor for refrigeration and refrigeration. More specifically, the pipe connection part is replaced by a single steel pipe or a double steel pipe and a pipe connection part that protrudes out of the compressor uses a copper pipe. It is possible to reduce the production cost of the compressor by reducing the copper material used in the present invention, and relates to the pipe connection device of the refrigeration and refrigeration compressor for reducing the welding area to improve the quality of the compressor.

냉장고 등과 같은 냉동장치는 열교환 매체를 상변화시키기 위하여 흡입, 압축, 펌핑작용을 연속적으로 수행하는 압축기와, 압축기로부터 펌핑되는 열교환매체를 액화시키기 위한 응축기와, 응축된 열교환 매체를 교축밸브를 통하여 증발시킴으로써 증발잠열을 흡수하는 증발기 및 이들을 연결하는 배관을 포함하여 폐쇄회로를 구성한다.A refrigeration apparatus such as a refrigerator has a compressor that continuously performs suction, compression, and pumping operations to phase change the heat exchange medium, a condenser for liquefying the heat exchange medium pumped from the compressor, and evaporates the condensed heat exchange medium through the throttling valve. In this way, a closed circuit is formed, including an evaporator which absorbs latent heat of evaporation and a pipe connecting them.

압축기는 압축형태에 따라 왕복타입, 사판타입, 로터리 베인타입, 스크롤 타입 등 여러 종류의 것이 있는데, 가정용 냉장고 등에 이용되는 소형 압축기는 구동에 따른 소음을 줄이기 위하여 밀폐형으로 제작되고 있다.There are various kinds of compressors such as reciprocating type, swash plate type, rotary vane type and scroll type according to the compression type. Small compressors used in home refrigerators are manufactured in a closed type to reduce noise caused by driving.

도 1은 종래기술에 따른 밀폐형 압축기의 내부구성을 나타내는 도면이다.1 is a view showing the internal configuration of a hermetic compressor according to the prior art.

도 1을 참조하면, 종래기술에 따른 압축기는 상ㆍ하부로 구성되어 용접결합되며 내부에는 압축장치를 구비한 밀폐용기(10)와, 상기 밀폐용기(10)의 내부에 구비되며 냉매를 압축하여 응축기로 공급하는 압축장치(12)와, 냉동ㆍ냉장시스템을 순환하여 귀환하는 냉매를 유입하는 유입관(15)이 연결되는 유입관연결부(14) 및 상기 유입관연결부(14)를 통하여 유입된 냉매를 압축장치(12)로 압축한 후 응축기(미도시)로 이송하는 토출관(17)이 연결되는 토출관연결부(16)로 이루어진 관연결부(14,16)로 구성된다.Referring to Figure 1, the compressor according to the prior art is composed of the upper and lower welded and the inside is a sealed container (10) having a compression device, and the inside of the sealed container (10) and compresses the refrigerant The inlet pipe connection part 14 connected to the compression device 12 for supplying the condenser, the inlet pipe 15 for introducing the refrigerant circulating through the refrigerating and refrigerating system, and the inlet pipe connection part 14 are introduced. It consists of pipe connections (14, 16) consisting of a discharge pipe connecting portion 16 is connected to the discharge pipe 17 for compressing the refrigerant to the condenser (not shown) after compressing the compressor (12).

압축장치(12)는 고정자(21) 및 회전자(23)로 구성된 전동기구부와, 회전자(23)의 중앙에 압입 고정된 크랭크 샤프트(25)의 회전 동작에 의해 냉매를 유입, 압축 및 토출하는 압축기구부(27)로 구성되며, 외부로부터 전원을 공급받아 유입관연결부(14)를 통하여 유입되는 냉매를 압축하여 토출관연결부(16)를 통하여 고온·고압의 냉매를 토출한다.The compression device 12 introduces, compresses, and discharges refrigerant by a rotational operation of an electric mechanism part including a stator 21 and a rotor 23 and a crankshaft 25 press-fit fixed to the center of the rotor 23. Compressor mechanism 27 is configured to compress the refrigerant introduced through the inlet pipe connection part 14 by receiving power from the outside to discharge the high temperature and high pressure refrigerant through the discharge pipe connection part 16.

유입관연결부(14)는 일단이 밀폐용기(10)를 관통하여 외부로 돌출되며, 외부로 돌출된 유입관연결부(14)의 끝단에는 냉동·냉장시스템을 순환하여 냉동실 또는 냉장실 내부의 열을 회수한 냉매가 압축기(20)로 귀환하는 유입관(15)이 용접결합되어 있고, 타단은 유입되는 냉매의 소음을 흡수하는 흡입머플러(13)와 연결된다. 유입관연결부(14)와 흡입머플러(13)는 액상의 냉매가 압축기구부(27)의 실린더(31) 내로 유입되지 않도록 일정간격 떨어진 간접흡입방식을 취하고 있다.One end of the inlet pipe connection part 14 protrudes to the outside through the hermetic container 10, and at the end of the inlet pipe connection part 14 which protrudes to the outside, the freezing / refrigerating system is circulated to recover heat inside the freezing compartment or the refrigerating compartment. An inlet pipe 15 into which one refrigerant returns to the compressor 20 is welded and the other end is connected to a suction muffler 13 that absorbs noise of the refrigerant to be introduced. The inlet pipe connection part 14 and the suction muffler 13 take an indirect suction method spaced apart by a predetermined interval so that the liquid refrigerant does not flow into the cylinder 31 of the compression mechanism part 27.

토출관연결부(16)는 일단이 머플러관(30)에 연결되며, 타단은 밀폐용기(10) 를 관통하여 외부로 돌출된 상태에서 압축기(20)에 의하여 압축된 냉매를 응축기로 이송하는 토출관(17)이 연결된다. 토출관연결부(16)의 일단과 연결된 머플러관(30의 타단은 압축기구부(27)에 의하여 압축된 냉매가 배출되며, 상기 배출되는 냉매의 소음을 흡수하는 배기머플러(29)에 연결된다.Discharge pipe connecting portion 16 is one end is connected to the muffler pipe 30, the other end is discharge pipe for conveying the refrigerant compressed by the compressor 20 to the condenser in a state protruded to the outside through the sealed container 10 17 is connected. The other end of the muffler pipe 30 connected to one end of the discharge pipe connecting portion 16 is discharged from the refrigerant compressed by the compression mechanism 27, it is connected to the exhaust muffler 29 to absorb the noise of the discharged refrigerant.

냉동ㆍ냉장시스템을 순환하여 유입관(15)으로 귀환하는 냉매는 유입관연결부(14) 및 흡입머플러(13)를 거쳐 실린더(31)로 공급된다. 실린더(31)로 유입된 냉매는 압축기구부(31)에 의하여 압축된 다음 배기머플러(29)와 토출관연결부(16)를 지나 토출관(17)을 통하여 응축기로 이송된다.The refrigerant circulating in the refrigerating and refrigerating system and returned to the inlet pipe 15 is supplied to the cylinder 31 via the inlet pipe connecting portion 14 and the suction muffler 13. The refrigerant introduced into the cylinder 31 is compressed by the compression mechanism 31 and then passed through the exhaust muffler 29 and the discharge pipe connecting portion 16 to the condenser through the discharge pipe 17.

이와 같이 관연결부(14,16)는 일반적으로 밀폐용기(10)를 관통하여 외부로 돌출되어 외부시스템과 연결되는 유입관(15) 또는 토출관(17)과 연결되는 부분과, 밀폐용기(10) 내부에 구비되어 압축장치(12)에 연결되는 부분이 일체로서 L자 형상으로 구비된다.As described above, the pipe connection parts 14 and 16 are generally connected to the inlet pipe 15 or the discharge pipe 17 connected to the external system by penetrating the sealed container 10 and connected to the external system, and the sealed container 10. A portion provided inside) and connected to the compression device 12 is integrally provided in an L shape.

그리고, 관연결부(14,16)는 동(銅)도금을 한 강관에 비하여 5 내지 6배가량 비싼 고가의 동(銅)관이 사용된다.In addition, the pipe parts 14 and 16 are expensive copper pipes that are 5 to 6 times more expensive than copper-plated steel pipes.

상기와 같은 종래기술에 따른 밀폐형 압축기의 경우에, 관연결부(14,16)가 동관을 사용함으로써, 생산원가를 증가시키는 문제점이 있으며, 관연결부(14,16)가 밀폐용기(10)를 관통하는 부분 및 관연결부(14,16)와 유입관(15) 또는 토출관(17)이 결합하는 부위에 용접을 하여야 하므로 용접부위가 많아지는 문제점이 있다.In the case of the hermetic compressor according to the prior art as described above, there is a problem of increasing the production cost by using the pipes 14, 16, the copper pipe, the pipe 14, 16 penetrates the sealed container 10. There is a problem in that the welding site is increased because the welding portion should be welded to the portion and the joint portion (14, 16) and the inlet pipe 15 or the discharge pipe (17).

특히, 최근에는 원자재 가격이 급등함에 따라 생산원가에서 원자재 가격이 차지하는 비중에 점차 증가하여 원가를 절감하는 문제에 관한 관심이 고조되고 있으며, 이러한 노력은 제품의 부피나 무게도 감소시켜 줌으로서 제품경쟁에 있어서 상당한 도움을 주고 있다.In particular, as the price of raw materials has soared recently, there has been a growing interest in the issue of reducing costs by gradually increasing the share of raw material prices in production costs. This effort also reduces the volume and weight of products, leading to product competition. It is a great help.
