본 발명은 밀폐형 압축기에 관한 것으로, 더욱 상세하게는 압축기 내부의 오일이 토출 측으로 배출되는 현상을 최소화 할 수 있도록 한 밀폐형 압축기에 관한 것이다.The present invention relates to a hermetic compressor, and more particularly, to a hermetic compressor to minimize the phenomenon that the oil inside the compressor is discharged to the discharge side.

대한민국 공개특허공보 10-2004-0023069호(2004년 3월 18일 공개)에 개시된 바와 같은 밀폐형 회전압축기는 압축기의 동작이 이루어질 때 밀폐용기 하부에 고인 오일이 압축기구부 쪽으로 공급될 수 있도록 회전축에 오일유로가 형성되어 있다. 이 오일유로는 회전축의 하부로부터 상부까지 관통하는 형태로 형성되는 상승유로와, 상승유로의 중도에서 반경방향으로 연통하는 연통유로를 구비하여, 회전축이 고속으로 회전할 때 연통유로를 통해 반경방향으로 토출되는 오일이 압축기구부 쪽으로 공급될 수 있도록 되어 있다. 즉 연통유로를 통해 공급되는 오일이 압축기구부의 상부플랜지와 일체로 된 상부 축지지부의 내면과 회전축의 외면 사이로 공급되어 기기의 동작이 원활해질 수 있도록 하고 있다.The hermetic rotary compressor, as disclosed in Korean Patent Laid-Open Publication No. 10-2004-0023069 (published March 18, 2004), allows oil accumulated in the lower portion of the hermetic container to be supplied toward the compressor section when the compressor is operated. A flow path is formed. The oil passage has a rising passage formed in a form penetrating from the lower portion to the upper portion of the rotating shaft, and a communication passage communicating radially in the middle of the rising passage so that the rotating shaft rotates at a high speed in a radial direction through the communicating passage. The discharged oil can be supplied to the compression mechanism portion. In other words, the oil supplied through the communication flow path is supplied between the inner surface of the upper shaft support portion and the outer surface of the rotary shaft integrated with the upper flange of the compression mechanism so as to facilitate the operation of the device.

그러나 이러한 밀폐형 회전압축기는 연통유로를 통해 반경방향으로 분출하여 압축기구부의 상부 쪽으로 공급되는 오일 중에서 미립자 상태로 분출하는 오일이 밀폐용기 내부의 토출가스와 섞여 배출되기 때문에 압축기 내부의 오일량이 점차 감소하게 되는 문제가 있었다. 즉 연통유로를 통해 반경방향으로 분출하는 오일 중 미립자 성분이 전동기구부의 고정자와 회전자 사이의 틈새를 통해 토출가스와 함께 상승하여 배출되기 때문에 압축기를 장기간 사용할 경우 압축기 내부의 오일량이 감소하여 압축기구부의 마모가 생길 수 있는 문제가 있었다.However, the hermetic rotary compressor discharges radially through the communication flow path, so that the oil ejected in the particulate state from the oil supplied to the upper portion of the compression mechanism is discharged mixed with the discharge gas in the hermetic container. There was a problem. That is, since the particulate matter in the oil ejected in the radial direction through the communication flow path is discharged together with the discharge gas through the gap between the stator and the rotor of the electric mechanism part, the amount of oil in the compressor decreases when the compressor is used for a long time. There was a problem that can cause wear.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 압축기 내부의 오일이 토출 측으로 배출되는 현상을 최소화할 수 있도록 한 밀폐형 압축기를 제공하는 것이다.The present invention is to solve such a problem, it is an object of the present invention to provide a hermetic compressor to minimize the phenomenon that the oil inside the compressor is discharged to the discharge side.

In addition, the present invention is coupled to the upper portion of the sealed container 10 to minimize the phenomenon that some of the radially ejected oil through the second oil passage 53 is discharged together with the refrigerant gas inside the sealed container 10. An oil repellent coating layer 60 is provided on the inner surface of the upper cover 12 to reduce adhesion of oil. As shown in FIG. 3, the oil repellent coating layer 60 is formed by coating or coating a thin film on the inner surface of the upper cover 12 with a material such as silicon wax, phosphoric acid, or teflon, which can reduce the adhesion of oil. Is done.

이러한 피막층(60)의 구성은 압축기의 동작이 이루어질 때 제2오일유로(53) 를 통해 배출되는 미립자성분의 오일이 냉매가스와 함께 상승하여 상부커버(12)의 내면에 부착될 때 오일이 액적형태로 응집된 후 상부커버(12)의 내면으로부터 쉽게 분리되도록 함으로써 오일이 밀폐용기(10) 하부의 오일저장부 쪽으로 낙하하여 쉽게 회수 될 수 있도록 한 것이다. 즉 상부커버(12)의 내면에 부착되는 오일의 액적이 발유 피막층(60)으로 인해 상부커버(12)로부터 쉽게 분리되어 낙하하도록 함으로써 오일의 회수가 용이하도록 하고 이를 통해 오일이 토출되는 냉매가스와 함께 밀폐용기(10)의 외부로 배출되는 현상을 최소화 할 수 있도록 한 것이다.The composition of the coating layer 60 is when the oil of the particulate component discharged through the second oil passage 53 when the operation of the compressor rises with the refrigerant gas to adhere to the inner surface of the upper cover 12, oil droplets After agglomerated in the form, the oil is easily separated from the inner surface of the upper cover 12 so that the oil can be easily recovered by dropping toward the oil storage part of the lower container 10. That is, the droplets of oil attached to the inner surface of the upper cover 12 are easily separated from the upper cover 12 by the oil repellent coating layer 60 so that the oil is easily recovered and thus the refrigerant gas from which the oil is discharged. Together to minimize the phenomenon that is discharged to the outside of the sealed container (10).

다음은 이러한 구성의 본 발명에 따른 회전압축기의 동작을 설명한다.The following describes the operation of the rotary compressor according to the present invention in this configuration.

전동기구부(20)의 동작에 의해 회전축(21)이 회전하면 회전축(21)에 마련된 편심부(38)의 회전이 이루어지고, 이를 통해 압축실(31) 내부의 링 피스톤(39)이 편심회전을 한다. 또 압축실(31) 내부는 회전하는 링 피스톤(39)과 베인(40)의 동작에 의해 흡입구(42) 쪽과 연통되는 흡입공간과 토출구(43) 쪽과 연통되는 토출공간의 용적이 상반되도록 변화하는 현상이 반복되면서 흡입구(42)를 통해 흡입되는 저압의 냉매가 토출구(43) 쪽으로 가압 토출된다. 그리고 토출구(43)로부터 토출되는 냉매는 밀폐용기(10) 내부공간을 거쳐 상부의 토출배관(14)으로 배출된다. 이때 가압된 냉매는 밀폐용기(10) 내부의 회전자(23)와 고정자(22) 사이 틈새를 통해 상부의 토출배관(14) 쪽으로 상승한다.When the rotary shaft 21 is rotated by the operation of the power mechanism 20, the eccentric portion 38 provided on the rotary shaft 21 is rotated, through which the ring piston 39 inside the compression chamber 31 is eccentrically rotated. Do it. In addition, the inside of the compression chamber 31 is operated such that the volume of the suction space communicating with the suction port 42 side and the discharge space communicating with the discharge port 43 side are opposite by the operation of the rotating ring piston 39 and the vane 40. As the changing phenomenon is repeated, the low pressure refrigerant sucked through the suction port 42 is discharged to the discharge port 43. And the refrigerant discharged from the discharge port 43 is discharged to the upper discharge pipe 14 through the inner space of the sealed container 10. At this time, the pressurized refrigerant rises toward the upper discharge pipe 14 through a gap between the rotor 23 and the stator 22 inside the sealed container 10.

한편 이러한 압축동작이 이루어지는 동안 밀폐용기(10) 하부의 오일은 회전축(21)에 형성된 제1오일유로(51)와 제2오일유로(53)를 거쳐 압축기구부(30)의 상측으로 공급된다. 이때 제2오일유로(53)를 통해 분출하는 오일은 상부 축지지부 (35) 내면과 회전축(21) 외면 사이의 마찰부분으로 공급되어 기기의 윤활작용을 하므로 압축기구부(30)의 동작이 원활히 이루어진다. Meanwhile, during the compression operation, the oil under the sealed container 10 is supplied to the upper side of the compression mechanism 30 through the first oil channel 51 and the second oil channel 53 formed on the rotating shaft 21. At this time, the oil ejected through the second oil passage 53 is supplied to the friction portion between the inner surface of the upper shaft support portion 35 and the outer surface of the rotary shaft 21 to lubricate the device, thereby smoothly operating the compression mechanism 30. .

또한 제2오일유로(53)로부터 분출되는 오일 중 비산하는 오일은 배출되는 냉매가스와 함께 상부커버(12) 쪽으로 상승하여 상부커버(12) 내면에 부착되는데, 상부커버(12)의 내면에는 오일의 부착력을 감소시키는 피막층(60)이 형성되어 있기 때문에 상부커버(12) 내면에 부착되어 응집되는 액적상태의 오일이 상부커버(12) 내면으로부터 쉽게 분리되어 하부로 낙하된다. 즉 오일이 밀폐용기(10) 하부의 오일저장부 쪽으로 쉽게 회수된다. 따라서 본 발명의 압축기는 냉매가스와 함께 오일이 배출되는 현상을 최소화할 수 있어, 장기간 사용하더라도 밀폐용기(10) 하부의 오일량이 크게 감소하지 않아 압축기구부 원활한 윤활을 장기간 보장할 수 있게 된다.In addition, the oil splashing out of the oil ejected from the second oil passage 53 rises toward the upper cover 12 together with the refrigerant gas discharged, and is attached to the inner surface of the upper cover 12. The inner surface of the upper cover 12 is oil. Since the coating layer 60 is formed to reduce the adhesive force of the oil, the oil in the droplet state, which is attached to the inner surface of the upper cover 12 and aggregates, is easily separated from the inner surface of the upper cover 12 and falls to the lower side. That is, oil is easily recovered toward the oil storage part of the bottom of the sealed container 10. Therefore, the compressor of the present invention can minimize the phenomenon that the oil is discharged together with the refrigerant gas, even if it is used for a long time, the amount of oil in the lower portion of the hermetic container 10 is not greatly reduced, thereby ensuring a smooth lubrication of the compressor section.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 밀폐형 압축기는 밀폐용기의 상부커버 내면에 오일의 부착력을 감소시키는 피막층이 형성됨으로써 상부커버의 내면 쪽으로 상승하는 오일이 상부커버의 내면으로부터 쉽게 분리되어 회수되므로, 밀폐용기 내부의 오일이 냉매가스와 함께 외부로 배출되는 현상을 최소화할 수 있는 효과가 있다.As described in detail above, the hermetic compressor according to the present invention is formed on the inner surface of the upper cover of the sealed container is formed by the coating layer to reduce the adhesion of oil, so that the oil rising toward the inner surface of the upper cover is easily separated from the inner surface of the upper cover is recovered In addition, there is an effect to minimize the phenomenon that the oil inside the sealed container is discharged to the outside with the refrigerant gas.
