본 발명은 로타리 압축기에 관한 것으로서, 보다 상세하게는 압축기의 셀내부의 압력과 스프링의 힘에 의해 밸브가 상하방향으로 왕복운동을 하여 실린더에서 압축된 냉매가스를 토출할 수 있는 로타리 압축기에 관한 것이다.The present invention relates to a rotary compressor, and more particularly, to a rotary compressor capable of discharging a refrigerant gas compressed from a cylinder by reciprocating the valve in a vertical direction by pressure of a spring and pressure of a spring inside the compressor. .
지금까지 개발된 로타리 압축기의 일반적인 토출방식은 제1도와 제2a,2b도에 나타나 있는 것과 같이 모타회전자(4)를 따라 회전축(5)이 회전하게되면, 상기 회전축(5)의 편심 부위에 조립된 롤러(8)가 회전하게 되고 모타고정자(3)과 롤러(8)의 운동에 의해 토출관(12)이 같이 움직이게 되면서 실린더(7)의 가스 흡입구를 따라 들어온 흡입가스(A)를 고온 고압으로 만들게 된다.The general discharge method of the rotary compressor developed so far is that when the rotary shaft 5 is rotated along the motor rotor 4 as shown in FIGS. 1 and 2a and 2b, the rotary compressor 5 is disposed at an eccentric portion of the rotary shaft 5. The assembled roller 8 is rotated and the discharge tube 12 is moved together by the movement of the motor stator 3 and the roller 8 so that the suction gas A that has entered the gas inlet of the cylinder 7 is heated at a high temperature. It will be made high pressure.
여기서, 고온 고압으로 압축된 압축가스(B)는 제1실린더 토출구(C)를 따라 상측 베어링(6) 또는 하측 베어링(9)에 설치된 토출관(14)을 열면서 토출관(11) 내부로 압축가스가 토출되게 된다.Here, the compressed gas B compressed at a high temperature and high pressure is discharged into the discharge tube 11 while opening the discharge tube 14 installed in the upper bearing 6 or the lower bearing 9 along the first cylinder discharge port C. Compressed gas is discharged.
상기 압축가스가 토출할때 토출관(14)을 열게되고 흡입에서 압축될때 까지는 원래 위치로 돌아가 닫히게 되며 또한, 되고 흡입에서 압출될때 까지는 원래 위치로 돌아가 닫히게 되며 이때 밸브가 닫히는 순간 토출관(14)이 베어링 면에 접촉하면서 소음이 발생하게 되는데 이때 발생되는 소음이 로타리 압축기의 진동 소음의 발생 주원인이기도 하다.When the compressed gas is discharged, the discharge tube 14 is opened, and the suction tube is closed by returning to the original position until it is compressed in the suction, and the discharge tube 14 is closed by returning to the original position until the extrusion is extruded. Noise is generated when the bearing surface is in contact, and the noise generated at this time is a main cause of vibration noise of the rotary compressor.
근래에 와서는 로타리 압축기 용량에 따라 상측 베어링(6) 및 하측 베어링(9) 2곳에 동시에 토출관(14)을 설치하거나 압축실린더를 2개로 분리하는 방법 등을 통해 진동, 소음을 줄이는 노력을 하고 있으나 로타리 압축기의 특성상 토출밸브스프링을 사용한 압축가스(B)의 토출방법으로서는 소음을 줄이는데 문제가 있다.Recently, according to the capacity of rotary compressor, efforts are made to reduce vibration and noise by installing discharge pipes 14 on two upper bearings (6) and lower bearings (9) at the same time, or by separating two compression cylinders. However, the discharge method of the compressed gas (B) using the discharge valve spring due to the characteristics of the rotary compressor has a problem in reducing the noise.
따라서, 본 발명은 상기와 같은 제반결점을 해소하기 위해 안출한 것으로서, 본 발명의 목적은 냉매가스를 압축하여 토출하는데 있어 진동소음을 줄일 수 있는 로타리 압축기를 제공하는데 있다.Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a rotary compressor that can reduce vibration noise in compressing and discharging refrigerant gas.
상기의 목적을 달성하기 위해 본 발명은 베인과 롤러 등을 구비하여 흡입된 가스를 압축하여 토출하는 로타리 압축기에 있어서, 실린더의 일측단부에 실린더 토출구를 형성하고, 상기 실린더 토출구와 직각방향이 되도록 실린더 외부에 고착된 일측베어링에 제2배출구를 형성하며, 상기 실린더 토출구와 제2배출구 사이의 실린더 몸체에 조립구멍을 형성하여 제1배출구를 가진 밸브와 스프링을 삽입시켜 형성된 것을 특징으로 한다.In order to achieve the above object, the present invention provides a rotary compressor including a vane and a roller to compress and discharge the sucked gas, wherein a cylinder discharge port is formed at one end of the cylinder, and the cylinder is perpendicular to the cylinder discharge port. A second discharge port is formed on one side of the bearing fixed to the outside, and an assembly hole is formed in the cylinder body between the cylinder discharge port and the second discharge port to insert a valve and a spring having the first discharge port.
이하, 예시된 도면을 참조하여 본 발명을 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the illustrated drawings.
제3a,3b도는 본 발명에 따른 로타리 압축기가 흡입된 가스를 압축하였을때 작동관계를 나타낸 도면이고, 제4도는 본 발명에 따른 로타리 압축기가 흡입된 가스를 토출하였을때 작동관계를 나타낸 도면이다.3a and 3b are views showing the operating relationship when the rotary compressor according to the present invention compressed the sucked gas, Figure 4 is a view showing the operating relationship when the rotary compressor according to the present invention discharged the sucked gas.
본 발명의 로타리 압축기는 제3a,3b도 및 제4도에 도시된 바와 같이, 실린더(7)의 압축 공간 끝부분에 실린더 토출구(F)를 형성함과 동시에 상기 실린더(7)의 직각방향으로 상측 베어링(6)에 제2배출구(G)가 형성되어 있다.As shown in FIGS. 3A, 3B, and 4, the rotary compressor of the present invention forms a cylinder discharge port F at the end of the compression space of the cylinder 7, and at the same time in a direction perpendicular to the cylinder 7. The second discharge port G is formed in the upper bearing 6.
한편, 실린더(7)의 몸체에는 토출관(15)와 밸브 토출관(16)이 조립될 수 있는 조립구멍이 상기 제2배출구(G)와 일치되도록 형성되어 있다.On the other hand, the body of the cylinder 7 is formed so that the assembling hole into which the discharge pipe 15 and the valve discharge pipe 16 can be assembled is coincident with the second discharge port G.
그리고, 상기 토출관(15)는 압축가스 토출이 끝나면 토출관(16)에 의해 닫혀지도록 토출관(16)를 설치하고, 실린더의 가스압력이 높아지면 토출관(15)가 열리고 압축가스가 토출관(15)에 형성된 제1배출구(E)와 제2배출구(G)를 지나 토출되도록 형성되어 있다.The discharge tube 15 is provided with a discharge tube 16 to be closed by the discharge tube 16 after the discharge of the compressed gas. When the gas pressure of the cylinder is increased, the discharge tube 15 is opened and the compressed gas is discharged. It is formed to be discharged through the first discharge port (E) and the second discharge port (G) formed in the pipe (15).
상기한 바와 같은 구성을 가진 본 발명의 작동관계를 상세히 기술하면 다음과 같다.Referring to the operation of the present invention having the configuration as described above in detail.
제3a,3b도에 도시된 로타리 압축기에서 실린더(7)의 흡입구(D)로 흡입된 가스(A)는 토출관(12)과 롤러(8)의 작동에 의해 고온, 고압의 압축가스(B)로 된다.In the rotary compressors shown in FIGS. 3A and 3B, the gas A sucked into the inlet D of the cylinder 7 is a compressed gas B of high temperature and high pressure by the operation of the discharge pipe 12 and the roller 8. ).
상기 압축가스(B)는 상기 실린더 토출구(F)를 통한 후, 토출관(15)의 저면과 실린더의 내면 사이의 미세한 틈으로 흐르게 된다.After the compressed gas B passes through the cylinder discharge port F, the compressed gas B flows into a minute gap between the bottom surface of the discharge tube 15 and the inner surface of the cylinder.
이때, 상기 토출관(15)에 가해진 압축가스(B)의 압력이 토출관(16)의 탄성력 보다 높아지게 되면, 토출관(15)가 제4도에 도시된 바와 같이 상승되어, 실린더 토출구(F)에서 토출된 고온, 고압가스는 밸브(15)내에 형성된 제1배출구(E)와 토출관(16)에 형성된 제2배출구(G)를 통해 토출된다.At this time, when the pressure of the compressed gas B applied to the discharge tube 15 becomes higher than the elastic force of the discharge tube 16, the discharge tube 15 is raised as shown in FIG. 4, and the cylinder discharge port F ), The high temperature and high pressure gas discharged from the air is discharged through the first discharge port E formed in the valve 15 and the second discharge port G formed in the discharge pipe 16.
여기서 압축가스(B)의 압력을 높이는 것을 실린더 토출구(F) 크기가 많은 영향을 주며, 상기 압축가스(B)를 일정압력으로 유지시켜주는 것은 토출관(15)에 형성되어 압력을 조절해 주는 토출관(16)의 힘과 토출관(11)내압에 의해 유지된다.In this case, the pressure of the compressed gas (B) has a large influence on the size of the cylinder discharge port (F), and maintaining the compressed gas (B) at a constant pressure is formed in the discharge pipe (15) to control the pressure. It is maintained by the force of the discharge tube 16 and the internal pressure of the discharge tube 11.
한편, 실린더 토출구(F)를 통과해 토출되는 압축가스(B)의 압력이 토출관(16)의 탄성력보다 작으면 토출관(15)는 서서히 하강하게 되어 제3b도에 도시된 바와 같이 토출관(15)가 실린더 토출구(F)를 닫게 된다.On the other hand, if the pressure of the compressed gas B discharged through the cylinder discharge port F is less than the elastic force of the discharge tube 16, the discharge tube 15 is gradually lowered, as shown in Figure 3b discharge tube (15) closes the cylinder discharge port (F).
상술한 바와 같이 작동하는 본 발명의 로타리 압축기는 압축가스를 토출하는 압력과 스프링의 힘에 의해 토출가스를 안내하는 밸브를 상하방향으로 왕복운동을 하여 압축가스를 토출하므로, 토출시 진동소음을 최소화하는 장점이 있다.The rotary compressor of the present invention operating as described above discharges the compressed gas by reciprocating the valve guiding the discharge gas in the vertical direction by the pressure and the force of the spring to discharge the compressed gas, thereby minimizing vibration noise during discharge. There is an advantage.
