본 발명은 로터리 압축기의 유토출 저감 장치에 관한 것으로, 특히 토출관 입구에 유분리기를 장착한 로터리 압축기의 유토출 저감 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil discharge reducing apparatus for a rotary compressor, and more particularly, to an oil discharge reducing apparatus for a rotary compressor equipped with an oil separator at a discharge pipe inlet.

일반적으로 에어컨 등에 적용되는 로터리 압축기는 전동기구부에 결합한 회전축에 압축기구부의 롤링피스톤을 편심되게 결합하고, 롤링피스톤이 원형 실린더 내에서 선회운동을 하면서 냉매가스를 흡입 압축하여 토출하는 것으로, 종래의 로터리 압축기는 도 1에 도시한 바와 같다.In general, a rotary compressor applied to an air conditioner is eccentrically coupled to a rotating shaft coupled to an electric mechanism, and a rolling piston is eccentrically, and a rolling piston sucks and discharges refrigerant gas while rotating in a circular cylinder. The compressor is as shown in FIG.

이에 도시한 바와 같이 종래의 로터리 압축기는, 소정량의 오일이 채워지고 흡입관(SP)과 토출관(DP)을 구비하는 케이싱(1)의 내부에 전동기구부인 고정자(2) 및 회전자(3)를 설치하고, 그 중 회전자(3)의 중심에는 회전축(4)을 압입하며, 회전축(4)의 하부에는 냉매가스를 흡입 압축하는 압축기구부를 설치하여 이루어져 있다.As shown in the drawing, the conventional rotary compressor includes a stator 2 and a rotor 3 which are electric motor parts inside a casing 1 filled with a predetermined amount of oil and having a suction pipe SP and a discharge pipe DP. ), A rotary shaft (4) is press-fitted to the center of the rotor (3), and a compression mechanism for suction-pressing refrigerant gas is provided at the lower portion of the rotary shaft (4).

압축기구부는 케이싱(1)의 내주면에 고정하여 흡입관(SP)과 연통하는 원형의 실린더(5)와, 실린더(5)의 양측면에 밀착하는 동시에 회전축(4)이 관통하여 지지되는 상부베어링(6A) 및 하부베어링(6B)과, 회전축(4)에 접동하여 자전하면서 실린더(5)내에서 편심 회전하는 롤링피스톤(7)과, 롤링피스톤(7)의 외주면에 압접하여 롤링피스톤(7)의 선회운동시 직선운동을 하면서 실린더(5)를 흡입공간과 압축공간으로 구분하는 베인(미도시)을 포함하여 이루어져 있다. The compression mechanism is fixed to the inner circumferential surface of the casing 1 and has a circular cylinder 5 which communicates with the suction pipe SP, and an upper bearing 6A which is in close contact with both sides of the cylinder 5 and supported by the rotating shaft 4 therethrough. ) And the lower bearing 6B, the rolling piston 7 which eccentrically rotates in the cylinder 5 while rotating in rotation with the rotating shaft 4, and the outer circumferential surface of the rolling piston 7, It includes a vane (not shown) for dividing the cylinder (5) into a suction space and a compression space while performing a linear movement during the pivoting movement.                         

회전축(4)의 내부에는 오일유로(4a)가 축방향으로 길게 관통하도록 형성하고, 오일유로(4a)의 하단에는 케이싱(1)에 채워진 오일을 흡상하는 오일피더(미도시)가 장착하여 이루어져 있다.The oil passage 4a is formed in the rotary shaft 4 so as to penetrate long in the axial direction, and an oil feeder (not shown) is installed at the lower end of the oil passage 4a to suck up the oil filled in the casing 1. have.

도면중 미설명 부호인 6a는 토출구멍, 8은 토출밸브 조립체, 9는 토출머플러, A는 어큐뮬레이터이다.In the figure, reference numeral 6a denotes a discharge hole, 8 denotes a discharge valve assembly, 9 denotes a discharge muffler, and A denotes an accumulator.

상기와 같이 구성된 종래의 로터리 압축기의 동작은 다음과 같다.Operation of the conventional rotary compressor configured as described above is as follows.

즉, 고정자(2)에 전원을 인가하면 회전자(3)가 고정자(2)의 내부에서 회전하고, 이와 함께 회전축(4)이 회전하면서 롤링피스톤(7)이 실린더(5)내에서 편심 회전하며, 롤링피스톤(7)의 편심회전에 따라 냉매가스가 실린더(5)의 흡입공간으로 흡입되었다가 일정압력까지 지속적으로 압축되고, 실린더(5)의 압축공간 압력이 임계압력을 지나 케이싱(1)내의 압력보다 고압이 되는 순간 상부베어링(6A)에 장착한 토출밸브(9)가 열리면서 압축가스가 압축공간에서 케이싱(1)의 내부로 토출되며, 토출가스는 케이싱(1)과 고정자(2) 사이의 틈새 또는 고정자(2)와 회전자(3) 사이의 틈새 등을 통해 상부로 이동하여 토출관(DP)을 거쳐 냉동사이클시스템으로 배출한다.That is, when power is applied to the stator 2, the rotor 3 rotates inside the stator 2, and the rotating shaft 4 rotates with the rolling piston 7 eccentrically rotating in the cylinder 5. In addition, the refrigerant gas is sucked into the suction space of the cylinder (5) in accordance with the eccentric rotation of the rolling piston (7) is continuously compressed to a constant pressure, the pressure of the compression space of the cylinder (5) passes the critical pressure of the casing (1) At the moment when the pressure is higher than the pressure in the cylinder, the discharge valve 9 mounted on the upper bearing 6A is opened, and compressed gas is discharged into the casing 1 in the compression space, and the discharge gas is discharged from the casing 1 and the stator 2. ) Is moved upward through a gap between the stator 2 or between the stator 2 and the rotor 3 and discharged through the discharge pipe DP to the refrigeration cycle system.

이때, 케이싱(1)의 내부에 채워져 있던 오일은 회전축(4)의 오일피더(미도시) 및 오일유로(4a)에 의해 상단까지 흡상되었다가 비산되면서 각 습동부를 윤활하는 동시에 전동기구부를 냉각하면서 다시 케이싱(1)의 바닥으로 흘러내리게 되는 것이었다.At this time, the oil filled in the casing 1 is sucked up to the upper end by the oil feeder (not shown) and the oil flow path 4a of the rotating shaft 4, and lubricated each sliding part while being scattered, while cooling the electric mechanism part. While again flowing down to the bottom of the casing (1).

그러나, 상기와 같은 종래 로터리 압축기에 있어서는, 비산되는 오일의 일부가 토 출가스와 혼합되어 토출관(DP)을 통해 함께 토출되고, 이 토출관(DP)을 통해 냉매가스와 함께 토출되었던 오일이 냉동사이클시스템을 지나면서 압력이 강하되어 냉매관의 하부나 또는 구부러진 부위 등에 잔류하고, 이로 인해 토출되는 오일량에 비해 흡입되는 오일량이 적어져 결국 케이싱(1)내의 오일이 점진적으로 감소함에 따라 각 습동부에 오일부족으로 인한 건마모가 발생하면서 각 부품의 수명이 단축될 우려가 있었다.However, in the conventional rotary compressor as described above, a part of the oil scattered is mixed with the discharge gas and discharged together through the discharge pipe DP, and the oil discharged together with the refrigerant gas through the discharge pipe DP is frozen. As the pressure drops through the cycle system, it remains in the lower part of the refrigerant pipe or in a bent part, and as a result, the amount of oil to be sucked decreases compared to the amount of oil discharged, and eventually the oil in the casing 1 gradually decreases. Dry wear caused by oil shortage in the eastern part was likely to shorten the life of each part.

본 발명은 상기와 같은 종래 로터리 압축기가 가지는 문제점을 감안하여 안출한 것으로, 회전축으로부터 비산되는 오일이 토출가스와 함께 토출관을 통해 유출되는 것을 줄일 수 있는 로터리 압축기의 유토출 저감 장치를 제공하려는데 그 목적이 있다.The present invention has been made in view of the problems of the conventional rotary compressor as described above, to provide an oil discharge reduction device of the rotary compressor that can reduce the flow of the oil scattered from the rotary shaft through the discharge pipe with the discharge gas. There is a purpose.

본 발명의 목적을 달성하기 위하여, 흡입관과 토출관을 구비하고 소정량의 오일을 채운 케이싱의 내부에 고정자와 회전자로 이루어져 구동력을 발생하는 전동기구부와, 상기 전동기구부의 회전자와 함께 회전하는 회전축의 회전시 유체를 흡입 압축하여 토출하는 압축기구부와, 소정의 내부체적을 구비하여 토출관에 연통하도록 결합하는 유분리통과, 상기 유분리통의 내부에 설치하여 토출관으로 향하는 토출가스 중에서 오일을 분리하는 필터부재와, 상기 압축기구부에서 토출된 토출가스가 상기 유분리통으로 유도되도록 그 유분리통의 바닥면을 관통하여 상기 필터부재에 근접하도록 연장 삽입되는 토출안내관을 포함한 것을 특징으로 하는 로터리 압축기의 유토출 저감 장치가 제공된다.In order to achieve the object of the present invention, there is provided with a suction pipe and a discharge pipe and the rotor is filled with a predetermined amount of oil in the casing of the electric motor unit for generating a driving force, and rotating with the rotor of the electric machine unit A compression mechanism for suction and compression of the fluid upon rotation of the rotating shaft, an oil separation tube having a predetermined internal volume to be connected to the discharge tube, and an oil separation tube installed inside the oil separation cylinder to the discharge tube. And a filter member for separating and a discharge guide tube extending through the bottom surface of the oil separation cylinder to approach the filter member so that the discharge gas discharged from the compression mechanism portion is guided to the oil separation cylinder. An apparatus for reducing oil discharge is provided.

이하, 본 발명에 의한 로터리 압축기의 유토출 저감 장치를 첨부도면에 도시한 일 실시예에 의거하여 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the oil discharge reduction apparatus of the rotary compressor by this invention is demonstrated in detail based on one Example shown in an accompanying drawing.

도 2는 본 발명 로터리 압축기의 일례를 보인 종단면도이고, 도 3 및 도 4는 본 발명 로터리 압축기의 유토출 저감 장치를 보인 종단면도 및 일부를 파단하여 보인 사시도이다.Figure 2 is a longitudinal sectional view showing an example of the rotary compressor of the present invention, Figure 3 and Figure 4 is a longitudinal sectional view showing the oil discharge reduction device of the rotary compressor of the present invention and a perspective view showing a broken part.

이에 도시한 바와 같이 본 발명에 의한 유토출 저감장치가 구비된 로터리 압축기는, 소정량의 오일이 채워지고 흡입관(도 1에 도시)(SP)과 토출관(DP)을 구비한 케이싱(1)과, 케이싱(1)의 내부에 장착하여 구동력을 발생하도록 고정자(2)와 회전자(3)로 된 전동기구부와, 회전자(3)에 결합하여 함께 회전하고 케이싱(1)의 오일을 흡상하도록 오일유로(4a)를 축방향으로 관통 형성하는 회전축(4)과, 회전축(4)에 의해 전동기구부의 구동력을 전달받아 냉매가스를 흡입 압축하여 케이싱(1)의 내부로 토출하는 압축기구부와, 케이싱의 토출관(DP) 입구에 장착하여 토출가스와 오일을 분리하는 유분리장치(10)를 포함하여 구성된다.As shown in the drawing, the rotary compressor equipped with the oil discharge reducing device according to the present invention includes a casing 1 having a predetermined amount of oil filled therein and having a suction pipe (shown in FIG. 1) SP and a discharge pipe DP. And an electric mechanism part consisting of the stator 2 and the rotor 3 and the rotor 3 to be rotated together to be mounted inside the casing 1 to generate a driving force, and to suck up the oil of the casing 1. A rotary shaft 4 penetrating the oil channel 4a in the axial direction so as to receive the driving force of the electric mechanism by the rotary shaft 4, and a compressor mechanism for sucking and compressing the refrigerant gas and discharging it into the casing 1; And an oil separation device 10 mounted at an inlet of the discharge pipe DP of the casing to separate the discharge gas and the oil.

유분리장치(10)는 도 3 및 도 4에 도시된 바와 같이, 소정의 내부체적을 구비하여 토출관(DP)에 연통하도록 결합하는 유분리통(11)과, 유분리통(11)의 내부에 설치하여 토출관(DP)으로 향하는 토출가스 중에서 오일을 분리하는 필터부재(12)로 이루어진다.As shown in FIGS. 3 and 4, the oil separation device 10 includes a oil separation cylinder 11 having a predetermined internal volume and coupled to communicate with the discharge pipe DP, and inside the oil separation cylinder 11. It is provided with a filter member 12 for separating the oil from the discharge gas toward the discharge pipe (DP).

유분리통(11)은 필터부재(12)에 의해 분리된 오일을 케이싱(11)의 내부로 배출하는 오일회수구(11a)를 바닥면 일 측에 형성하되, 바닥면은 오일회수구(11a)쪽으로 하향 경사지게 형성하는 것이 바람직하다.The oil separation container 11 has an oil recovery port 11a for discharging the oil separated by the filter member 12 into the casing 11 on one side of the bottom surface, but the bottom surface of the oil recovery port 11a. It is preferable to form it inclined downwardly.

또, 유분리통(11)의 바닥면 중앙에는 압축기구부에서 토출한 토출가스를 유분리통(11)으로 유도하는 토출안내관(13)을 필터부재(12)에 근접하도록 연장 삽입하여 고정판(14)으로 고정한다. 고정판(14)은 다수개의 배유공(14a)을 구비한 환형으로 형성하여 그 내주면은 토출안내관(13)의 외주면에 고정하는 반면 외주면은 유분리통(11)의 내주면에 고정한다.In addition, in the center of the bottom surface of the oil separation cylinder 11, a discharge guide tube 13 for guiding the discharge gas discharged from the compression mechanism portion into the oil separation cylinder 11 is extended and inserted close to the filter member 12 to fix the plate 14. Secure with. The fixing plate 14 is formed in an annular shape having a plurality of drainage holes 14a so that its inner circumferential surface is fixed to the outer circumferential surface of the discharge guide tube 13 while the outer circumferential surface is fixed to the inner circumferential surface of the oil separation tube 11.

필터부재(12)와 토출관(DP)의 입구 사이에는 그 필터부재(DP)를 거친 토출가스에서 오일을 다시 분리하도록 가스통공(15a)을 다수개 구비한 유분리판(15)을 장착한다.Between the filter member 12 and the inlet of the discharge pipe DP, an oil separation plate 15 having a plurality of gas through holes 15a is mounted to separate oil from the discharge gas which has passed through the filter member DP. .

필터부재(12)는 소정의 두께를 갖는 망상부재로 형성하여 그 외주면을 유분리통(11)의 내주면에 용접 등으로 고정 결합한다. 또, 필터부재(12)는 그 메시 정도가 지나치게 촘촘할 경우 냉매의 유로저항을 증가시켜 압축기 효율이 저하되는 반면 너무 넓을 경우에는 유분리 작용이 저하될 우려가 있으므로 이를 감안하여 적절한 메시 크기로 형성하여야 한다.The filter member 12 is formed of a reticular member having a predetermined thickness and fixedly coupled to the inner circumferential surface of the oil separation tube 11 by welding or the like. In addition, the filter member 12 is formed with an appropriate mesh size in consideration of this, because if the mesh degree is too dense, the flow efficiency of the refrigerant is increased to reduce the compressor efficiency while the filter member 12 is too wide. shall.

도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.

도면중 미설명 부호인 6a는 토출구멍, 8은 토출밸브 조립체, 9는 토출머플러, A는 어큐뮬레이터이다.In the figure, reference numeral 6a denotes a discharge hole, 8 denotes a discharge valve assembly, 9 denotes a discharge muffler, and A denotes an accumulator.

상기와 같은 밀폐형 회전식 압축기의 일반적인 동작은 종래와 유사하다.The general operation of such a hermetic rotary compressor is similar to the prior art.

즉, 전동기구부에 전원을 인가하여 회전축(4)이 회전자(3)와 함께 회전을 하면, 회전축(4)의 편심부(미부호)에 결합한 롤링피스톤(7)이 실린더(5)의 밀폐공간에서 편심 회전을 하면서 냉매가스를 흡입영역으로 흡입하였다가 점차 압축영역으로 밀어 일정압력까지 압축하고, 압축영역의 압력이 케이싱(1)의 내부압력보다 높아지는 시점에서 압축가스를 케이싱(1)으로 토출하며, 토출된 압축가스는 토출관(DP)을 통해 냉동사이클장치로 토출되었다가 다시 흡입되는 일련의 과정을 반복한다.That is, when the rotary shaft 4 rotates together with the rotor 3 by applying power to the electric mechanism, the rolling piston 7 coupled to the eccentric portion (unsigned) of the rotary shaft 4 seals the cylinder 5. The refrigerant gas is sucked into the suction zone while being eccentrically rotated in the space and gradually pushed into the compression zone to compress to a certain pressure. At the point where the pressure in the compression zone becomes higher than the internal pressure of the casing 1, the compressed gas is moved into the casing 1. After the discharge, the discharged compressed gas is discharged to the refrigerating cycle apparatus through the discharge pipe (DP) and repeated a series of processes to be sucked again.

이때, 실린더(5)에서 토출되는 압축가스는 회전축(4)에서 비산하는 오일과 섞여 토출될 우려가 있으나, 토출관(DP)의 입구에는 필터부재(12)를 구비한 유분리통(11)이 설치되어 있어 먼저 토출안내관(13)을 따라 유분리통(11)으로 유입되고, 이어서 필터부재(12)를 통과하면서 가스는 토출관(DP)을 통해 상기한 냉동사이클로 유입되는 반면 오일은 필터부재(12)에 걸러져 케이싱(11)으로 다시 회수된다.At this time, the compressed gas discharged from the cylinder (5) may be discharged mixed with the oil flying from the rotary shaft (4), but the oil separation cylinder (11) having a filter member 12 at the inlet of the discharge pipe (DP) First, the oil is introduced into the oil separation cylinder 11 along the discharge guide tube 13, and then the gas is introduced into the refrigeration cycle through the discharge tube DP while the oil passes through the filter member 12. Filtered by (12), it is recovered to the casing (11) again.

이를 보다 상세히 살펴보면, 오일을 함유한 가스가 필터부재(12)를 거치면서 가스는 필터부재(12)를 통과하는 반면 오일은 필터부재(12)에 걸러져 통과하지 못하게 되는데, 필터부재(12)를 통과한 가스는 다시 유분리판(15)을 거치면서 아직 남아 있던 오일도 가스에서 분리하게 된다. 이렇게 분리된 오일은 필터부재(12)에 의해 걸러진 오일과 함께 고정판(14)의 배유공(14a)을 통해 유분리통(11)의 바닥면으로 흘러내려 오일 회수구(11a)를 통해 케이싱(1)으로 회수되므로 압축기가 장시간 운전을 지속하더라도 오일이 원활하게 공급될 수 있다.Looking at this in more detail, while the gas containing the oil passes through the filter member 12, the gas passes through the filter member 12, while the oil is filtered out of the filter member 12, it does not pass through, the filter member 12 The gas passed through the oil separation plate 15 again separates the remaining oil from the gas. The oil separated in this way flows down to the bottom surface of the oil separation container 11 through the drain hole 14a of the fixing plate 14 together with the oil filtered by the filter member 12, and the casing 1 through the oil recovery port 11a. ), The oil can be supplied smoothly even if the compressor is operated for a long time.

한편, 유분리통(11)을 토출관(DP)에 장착함에 따라 회전자(3)와 기구부를 용이하게 분리할 수 있을 뿐만 아니라 회전자의 파손도 미연에 방지할 수 있다. On the other hand, as the oil separator 11 is mounted on the discharge pipe DP, not only the rotor 3 and the mechanism part can be easily separated, but also the damage of the rotor can be prevented in advance.

본 발명에 의한 로터리 압축기의 유토출 저감 장치는, 소정의 내부체적을 구비하고 그 내부에 오일분리를 위한 필터부재를 구비하는 유분리통을 토출관의 입구에 장착함으로써, 압축기 구동시 필요한 오일이 토출가스에 섞여 유출되는 것을 줄여 압축기의 장시간 운전에도 오일 공급이 원활하게 유지되도록 함에 따라 압축기의 안정 성과 신뢰성을 향상할 수 있다.
The oil discharge reduction device of the rotary compressor according to the present invention is provided with an oil separation container having a predetermined internal volume and a filter member for oil separation therein at the inlet of the discharge pipe, whereby the oil required for driving the compressor is discharged. It is possible to improve the stability and reliability of the compressor by reducing the outflow by mixing with gas to keep the oil supply smooth even during long operation of the compressor.
