스크롤압축기용 오일분리구조{OIL SEPARATING STRUCTURE FOR SCROLL TYPE COMPRESSOR}Oil Separation Structure for Scroll Compressor {OIL SEPARATING STRUCTURE FOR SCROLL TYPE COMPRESSOR}

본 발명은 스크롤압축기에 관한 것으로, 보다 상세하게는 스크롤압축기에서 토출되는 압축냉매에서 오일성분을 분리함으로써 냉매의 열교환효율을 향상시킬 수 있는 스크롤압축기용 오일분리구조에 관한 것이다. The present invention relates to a scroll compressor, and more particularly, to an oil separation structure for a scroll compressor that can improve the heat exchange efficiency of the refrigerant by separating the oil component from the compressed refrigerant discharged from the scroll compressor.

스크롤압축기는 프랑스의 Leon Creux에 의해 개발되어 1905년 미국에서 특허를 취득하였으나 초정밀가공기술 및 가스누설 방지기술의 적용이 가능해진 1980년대 들어와서 그 실용화가 이루어졌다. 이러한 스크롤압축기는 1981년에 Sanden이 자동차 에어컨용 냉매압축기로, 1983년에 Hitachi가 거주형 에어컨용 냉매압축기로 개발하여 그 실용화에 성공한 후에, 많은 제조업체에서 보다 개선된 구조를 구현하기 연구 및 개발이 진행되고 있다. The scroll compressor was developed by Leon Creux, France, and obtained a patent in the United States in 1905. However, the scroll compressor was put into practical use in the 1980s when ultra precision processing technology and gas leakage prevention technology could be applied. This scroll compressor was developed by Sanden in 1981 as a refrigerant compressor for automobile air conditioners and Hitachi in 1983 as a refrigerant compressor for residential air conditioners. It's going on.

스크롤압축기는 다른 종류의 압축기에 비해 고효율, 저소음, 저진동 및 경량 등의 장점을 가지고 있으며, 특히 인버터를 장착하였을 때의 적합성 및 압축기 내에 액냉매나 이물질이 주입되었을 때 과압을 자동으로 방지할 수 있는 구조적 특징을 가지고 있다. 이러한 장점에 의해 현재 스크롤압축기의 사용범위는 냉방능력이 2~20ton으로 확장되었으며, 이는 거주형 에어컨 뿐만 아니라 룸에어컨, 영업용 에어컨 등에도 적용가능하다. Scroll compressor has advantages such as high efficiency, low noise, low vibration and light weight compared to other types of compressors. Especially, it is suitable for the installation of inverter and it can automatically prevent overpressure when liquid refrigerant or foreign matter is injected into the compressor. It has structural features. Due to these advantages, the current range of use of scroll compressors has been extended to 2 to 20 tons of cooling capacity.

이러한 스크롤압축기는 서로 맞물려 상대적으로 선회가능한 2개의 스크롤을 포함하고, 2개의 스크롤은 고정스크롤(fixed scroll) 및 선회스크롤(orbiting scroll)로 구성된다. 각 스크롤은 원형 단부판(circular end plate)과 이 원형 단부판에서 돌출된 나선형요소(wrap or spiral element)를 가진다. 이에 고정스크롤 및 선회스크롤의 각 나선형요소는 서로 맞물려 배치되고, 선회스크롤이 고정스크롤에 대해 상대적으로 선회함에 따라 선회스크롤의 나선형요소와 고정스크롤의 나선형요소 사이에는 그 체적이 가변되면서 이동하는 하나 이상의 유체포켓(fluid pocket)이 형성된다. 선회스크롤의 선회작동이 진행될수록 유체포켓은 하우징의 토출포트로 이동하면서 그 체적이 감소하고, 이에 따라 유체포켓 내의 냉매유체는 압축되어 토출포트를 통해 토출된다. Such scroll compressors include two scrolls that are relatively pivotable in engagement with each other, and the two scrolls consist of a fixed scroll and an orbiting scroll. Each scroll has a circular end plate and a wrap or spiral element protruding from the circular end plate. Accordingly, each of the spiral elements of the fixed scroll and the swing scroll is interlocked with each other, and one or more of the spiral scrolls of the swing scroll and the fixed scroll spiral elements vary in volume as the swing scroll pivots relative to the fixed scroll. A fluid pocket is formed. As the turning operation of the turning scroll proceeds, the fluid pocket moves to the discharge port of the housing, and its volume decreases. Accordingly, the refrigerant fluid in the fluid pocket is compressed and discharged through the discharge port.

스크롤압축기의 선회스크롤은 구동축에 의해 구동되며, 이 구동축은 외부의 동력원에 의해 구동한다. 선회스크롤은 편심부시를 매개로 구동축에 대해 편심되게 설치되고, 구동축의 회전에 의해 선회스크롤은 구동축의 중심에 대해 편심적으로 선회한다. 구동축, 편심부시, 선회스크롤의 회전접촉하는 부분에는 베어링이 개재됨으로써 그 회전을 지지한다. The swing scroll of the scroll compressor is driven by a drive shaft, which is driven by an external power source. The swing scroll is eccentrically installed with respect to the drive shaft via the eccentric bush, and the swing scroll rotates eccentrically with respect to the center of the drive shaft by the rotation of the drive shaft. The bearing is interposed between the drive shaft, the eccentric bush, and the rotating scroll to support the rotation thereof.

압축기의 원활한 작동성 내지 내구성 등을 도모하기 위하여 베어링에는 적절한 윤활이 제공되어야 하며, 이러한 베어링의 적절한 윤활을 위해 냉매유체에는 미량의 오일이 함유되어 있다. 이에 오일이 함유된 냉매유체가 구동축, 편심부시, 선회스크롤 등의 베어링으로 이동하면서 베어링을 윤활하도록 구성된다. Proper lubrication should be provided to the bearings to achieve smooth operability and durability of the compressor, and a small amount of oil is contained in the refrigerant fluid for proper lubrication of such bearings. The oil-containing refrigerant fluid is configured to lubricate the bearing while moving to a bearing such as a drive shaft, an eccentric bush, a swing scroll, and the like.

스크롤압축기는 유체포켓에 의해 압축된 냉매를 증발기측으로 토출하고, 이렇게 토출되는 압축냉매에는 윤활을 위한 오일이 함유되어 있다. 이에 따라, 스크롤압축기는 오일을 함유한 압축냉매에서 오일을 분리한 후에, 이 분리된 오일을 하우징 내의 저압부로 리턴시킴으로써 토출되는 압축냉매의 열교환효율을 증대시킴과 더불어 오일의 낭비를 최소화할 수 있는 오일분리구조가 구비되어 있다. The scroll compressor discharges the refrigerant compressed by the fluid pocket to the evaporator side, and the compressed refrigerant thus discharged contains oil for lubrication. Accordingly, the scroll compressor separates the oil from the compressed refrigerant containing oil, and then returns the separated oil to the low pressure part in the housing to increase the heat exchange efficiency of the discharged compressed refrigerant and minimize waste of oil. Oil separation structure is provided.

한편, 종래의 스크롤압축기는 리어하우징의 내측면에 오일세퍼레이터가 설치되어 있으므로, 리어하우징 측에 토출포트를 형성함에 있어 다양한 위치에 형성할 수 없는 설계 상의 제한이 뒤따르는 단점이 있었다. On the other hand, the conventional scroll compressor is provided with an oil separator on the inner side of the rear housing, there is a disadvantage that the design restrictions that can not be formed in various positions in forming the discharge port on the rear housing side.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로, 오일세퍼레이터를 고정스크롤 측에 장착하는 구조를 적용함으로써 리어하우징의 보다 다양한 위치에 토출포트를 형성할 수 있어 그 설계자유도를 대폭 향상시킬 수 있는 스크롤압축기용 오일분리구조를 제공하는 데 그 목적이 있다.

In addition, an oil return passage 17 is formed at a portion adjacent to the closing portion 15b of the receiving portion 15, and one end of the oil return passage 17 communicates with the oil communication passage 16b, and the oil return passage ( The other end of 17) communicates with the oil storage space 13 of the fixed scroll 10 and the rear housing 30, and the oil return passage 17 is formed with a smaller diameter than the oil communication passage 16b.

이와 같은 구성에 의해, 고정스크롤(10) 및 리어하우징(30)의 냉매유입공간(11, 31)으로 오일을 함유한 압축냉매가 유입되면, 압축냉매는 냉매유입공(15c)을 통해 수용부(15) 내의 오일세퍼레이터(20)로 유입되고, 오일세퍼레이터(20)는 냉매와 오일 성분을 분리한다. 이렇게 분리된 냉매는 수용부(15)의 개구(15a)를 통과하여 냉매토출공간(12, 32)측으로 이송되고, 오일은 오일연통로(16b) 및 오일리턴통로(17)를 통과하여 오일저장공간(13, 33)측으로 이송된다. By such a configuration, when compressed refrigerant containing oil flows into the refrigerant inlet spaces 11 and 31 of the fixed scroll 10 and the rear housing 30, the compressed refrigerant is accommodated through the refrigerant inlet hole 15c. It flows into the oil separator 20 in 15, and the oil separator 20 isolate | separates a refrigerant | coolant and an oil component. The separated refrigerant passes through the opening 15a of the accommodating part 15 and is transferred to the refrigerant discharge spaces 12 and 32, and the oil passes through the oil communication path 16b and the oil return path 17 to store the oil. It is conveyed to the space 13, 33 side.

냉매토출공간(12, 32)으로 이송된 냉매는 리어하우징(30)의 토출포트(미도시)를 통해 외부로 토출되고, 오일저장공간(13, 33)으로 이송된 오일은 압력차이에 의해 전방하우징(미도시)의 내부공간으로 리턴된다. The refrigerant transferred to the refrigerant discharge spaces 12 and 32 is discharged to the outside through a discharge port (not shown) of the rear housing 30, and the oil transferred to the oil storage spaces 13 and 33 is moved forward by the pressure difference. Return to the interior space of the housing (not shown).

이와 같이, 본 발명은 오일세퍼레이터(20)를 수용하는 수용부(15)를 고정스크롤(10)측에 형성함으로써 리어하우징(30)의 토출포트(미도시)에 대한 설계자유도를 대폭 향상시킬 수 있는 장점이 있다. As described above, the present invention can greatly improve the design freedom of the discharge port (not shown) of the rear housing 30 by forming the receiving portion 15 accommodating the oil separator 20 on the fixed scroll 10 side. There is an advantage.
