이에 도시한 바와 같이 종래 왕복동식 압축기는, 케이싱(10)의 내부에 탄력적으로 설치하는 프레임 유니트(20)와, 프레임 유니트(20)에 설치하여 전동기구부를 이루는 왕복동식 모터(30)와, 왕복동식 모터(30)의 가동자(33)에 결합하여 함께 직선으로 왕복운동을 하면서 냉매가스를 흡입 압축하여 토출하는 압축 유니트(40)와, 압축 유니트(40)의 공진운동을 유도하도록 프레임 유니트(20)와 압축 유니트(40) 사이에 설치하는 공진스프링 유니트(50)를 포함하고 있다.As shown in the drawing, the conventional reciprocating compressor includes a frame unit 20 elastically installed inside the casing 10, a reciprocating motor 30 mounted on the frame unit 20 to form an electric mechanism, and a reciprocating method. Compression unit 40 coupled to the mover 33 of the same type motor 30 to reciprocate linearly together and suction and compress the refrigerant gas, and a frame unit to induce the resonant movement of the compression unit 40. 20 and a resonant spring unit 50 provided between the compression unit 40.

케이싱(10)에는 냉매가스를 냉동시스템(미도시)에서 흡입하는 가스흡입관(SP)과 압축한 냉매가스를 냉동시스템으로 토출하는 가스토출관(DP)을 설치하고, 그 중 가스토출관(DP)은 전술한 바와 같이 압축 유니트(40)의 토출공간(S)에 루프 파이프(roop pipe)(60)로 연결하고 있다.The casing 10 is provided with a gas suction pipe SP for sucking refrigerant gas from a refrigeration system (not shown) and a gas discharge pipe (DP) for discharging the compressed refrigerant gas into the refrigeration system. ) Is connected to the discharge space S of the compression unit 40 by a loop pipe 60.

또, 가스토출관(DP)은 도 2에서와 같이 정면투영시 엘(L)자 모양으로 형성하여 케이싱의 하반부에 관통한 후 직접 용접하여 고정하고 있다.In addition, as shown in Fig. 2, the gas discharge pipe DP is formed in an L-shape at the time of front projection, penetrates into the lower half of the casing, and is directly welded and fixed.

도면중 미설명 부호인 21 및 22 및 23은 전방 및 중간 및 후방 프레임, 31 및 32는 외측 및 내측 고정자, 41은 실린더, 42는 피스톤, 43은 흡입밸브, 44는 토출밸브 조립체, 51 및 52는 전방측 및 후방측 공진스프링, P는 압축공간, S는 토출공간이다.In the drawings, reference numerals 21 and 22 and 23 are front and middle and rear frames, 31 and 32 are outer and inner stators, 41 is cylinder, 42 is piston, 43 is suction valve, 44 is discharge valve assembly, 51 and 52 Is the front and rear resonant springs, P is the compression space, and S is the discharge space.

상기와 같은 종래 왕복동식 압축기는 다음과 같이 동작한다.The conventional reciprocating compressor as described above operates as follows.

즉, 왕복동식 모터(30)에 전원을 인가하면, 그 왕복동식 모터(30)의 외측 고정자(31)와 내측 고정자(32) 사이에 플럭스(flux)가 형성되어 가동자(33)가 플럭스의 방향에 따라 움직이면서 공진스프링 유니트(50)에 의해 직선으로 왕복운동을 하고, 이와 함께 피스톤(42)이 실린더(41)의 내부에서 직선으로 왕복운동을 하면서 그 실린더(41)의 압축공간(P)에 압력차를 발생시킴으로써 냉매가스를 가스흡입관(SP)을 통해 상기한 압축공간(P)으로 흡입하여 일정 압력까지 압축하였다가 가스토출관(DP)을 통해 토출하는 일련의 과정을 반복한다.That is, when power is applied to the reciprocating motor 30, a flux is formed between the outer stator 31 and the inner stator 32 of the reciprocating motor 30, so that the movable element 33 is formed of flux. While moving along the direction, the resonant spring unit 50 reciprocates in a straight line, and the piston 42 reciprocates in a straight line in the cylinder 41 while the compression space P of the cylinder 41 By generating a pressure difference in the gas, the refrigerant gas is sucked into the compression space P through the gas suction pipe SP, compressed to a predetermined pressure, and then discharged through the gas discharge pipe DP.

이때, 왕복동식 모터(30)와 압축 유니트(40)에서 발생하는 진동은 자체 진동 흡수 기능을 가지는 루프파이프(60)에 의해 일정 정도 감쇄되면서 압축기 진동이 감소되는 것이었다.At this time, the vibration generated in the reciprocating motor 30 and the compression unit 40 was reduced by a certain degree by the loop pipe 60 having its own vibration absorbing function to reduce the compressor vibration.

그러나, 상기와 같은 종래 왕복동식 압축기는, 가스토출관(DP)이 케이싱(10)에 직접 고정됨에 따라 루프파이프(60)의 비틀림 진동(torsional vibration)이 상기한 가스토출관(DP)을 통해 케이싱(10)으로 전달되면서 압축기 소음을 유발시키는 문제점이 있었다.However, in the conventional reciprocating compressor as described above, the torsional vibration of the loop pipe 60 is transmitted through the gas discharge pipe DP as the gas discharge pipe DP is directly fixed to the casing 10. There was a problem causing the compressor noise while being delivered to the casing (10).

본 발명은 상기와 같은 종래 왕복동식 압축기가 가지는 문제점을 감안하여 안출한 것으로, 가스토출관과 케이싱 사이에 전달되는 진동을 감쇄하여 소음을 줄일 수 있는 왕복동식 압축기의 소음 저감 장치를 제공하려는데 본 발명의 목적이 있다. The present invention has been made in view of the problems of the conventional reciprocating compressor as described above, to provide a noise reduction device of the reciprocating compressor that can reduce the noise by attenuating the vibration transmitted between the gas discharge pipe and the casing. There is a purpose.

The piston 42 is coupled to the reciprocating motor 30, which is installed in the frame unit 20, and the mover 33 reciprocates linearly, and the mover 33 of the reciprocating motor 30.

And a resilient spring unit 50 installed between the compression unit 40 and a sliding member that is slidably inserted into the outer circumferential surface of the gas discharge pipe DP to absorb vibrations transmitted through the gas discharge pipe DP. 100).

가스흡입관(SP)과 가스토출관(DP)은 모두 케이싱(10)의 일측에 관통하여 용접 고정하되, 그 중 가스토출관(DP)은 엘(L)자 모양으로 형성하여 내측 끝단은 탄성력을 가지는 루프파이프(60)를 이용하여 압축 유니트(40)의 토출측에 연결하는 반면 외측 끝단은 냉동사이클장치의 냉매관(미도시)에 직접 연결하여 이루어진다.The gas suction pipe SP and the gas discharge pipe DP both penetrate and weld to one side of the casing 10, of which the gas discharge pipe DP is formed in an L shape so that the inner end has an elastic force. The branch is connected to the discharge side of the compression unit 40 using the loop pipe 60, while the outer end is directly connected to the refrigerant pipe (not shown) of the refrigeration cycle apparatus.

미끄럼부재(100)는 도 4에서와 같이 케이싱(10)의 안쪽에 위치하는 가스토출관(DP)에 미끄러지게 삽입하거나 또는 도 5에서와 같이 케이싱(10)의 바깥쪽에 위치하는 가스토출관(DP)에 미끄러지게 삽입하여 상기한 가스토출관(DP)과의 마찰에 의해 진동을 감쇄하거나 또는 자체 마찰에 의해 진동을 감쇄할 수 있도록 가는 선재를 코일스프링과 같이 나선형으로 감아 형성하는 코일질량체로 이루어진다.The sliding member 100 is slidably inserted into the gas discharge pipe DP positioned inside the casing 10 as shown in FIG. 4, or the gas discharge pipe positioned outside the casing 10 as shown in FIG. 5. Slidingly inserted into the DP) to reduce the vibration by the friction with the gas discharge pipe (DP) or to the coil mass to form a thin wire wound spirally like a coil spring to attenuate the vibration by its own friction Is done.

또, 미끄럼부재(100)는 그 끝단, 예컨대 케이싱(10)에 접하는 일측 끝단이 상기한 케이싱(10)과 접촉할 수 있도록 설치하는 것이 마찰을 증가시켜 그만큼 진동을 감쇄할 수 있어 바람직하다.In addition, it is preferable that the sliding member 100 be installed such that one end of the sliding member 100 in contact with the casing 10 can contact the casing 10 so as to increase the friction and attenuate the vibration.

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 21 및 22 및 23은 전방 및 중간 및 후방 프레임, 31 및 32는 외측 및 내측 고정자, 43은 흡입밸브, 44는 토출밸브 조립체, 51 및 52는 전방측 및 후방측 공진스프링, P는 압축공간, S는 토출공간이다.In the drawings, reference numerals 21 and 22 and 23 are front and middle and rear frames, 31 and 32 are outer and inner stators, 43 are suction valves, 44 are discharge valve assemblies, 51 and 52 are front and rear resonant springs. , P is a compression space, S is a discharge space.

상기와 같은 본 발명 왕복동식 압축기의 소음 저감 장치는 다음과 같은 작용 효과를 갖는다.The noise reduction device of the reciprocating compressor of the present invention as described above has the following effects.

즉, 왕복동식 모터(30)의 고정자(31)(32)에 전원을 인가하면, 그 왕복동식 모터(30)의 가동자(33)와 결합한 피스톤(42)이 공진스프링 유니트(50)에 의해 실린더(41)의 내부에서 직선으로 왕복운동을 하면서 냉매가스를 압축공간(P)으로 흡입하여 일정 압력까지 압축하였다가 토출하는 일련의 과정을 반복한다.That is, when power is applied to the stators 31 and 32 of the reciprocating motor 30, the piston 42 coupled with the mover 33 of the reciprocating motor 30 is driven by the resonant spring unit 50. While reciprocating in a straight line in the cylinder 41, a series of processes of inhaling the refrigerant gas into the compression space P, compressing it to a predetermined pressure, and then discharging the gas are repeated.

이때, 왕복동식 모터(30)와 압축 유니트(40)는 도면의 좌우방향으로 움직이면서 진동을 유발하고, 이 진동은 루프파이프(60)와 가스토출관(DP)을 통해 케이싱(10)으로 전달되어 압축기 소음을 유발할 수 있으나, 본 발명에서와 같이 가스토출관(DP)의 외주면에 코일질량체로 된 미끄럼부재(100)를 삽입하는 경우에는 가스토출관(DP)이 도면의 좌우 방향으로 진동할 때 상기한 미끄럼부재(100)와 접촉하여 마찰을 발생하면서 진동이 감쇄되고 이로 인해 압축기의 진동과 소음이 현저하게 감소될 수 있다.At this time, the reciprocating motor 30 and the compression unit 40 is moved in the left and right direction of the drawing to cause a vibration, the vibration is transmitted to the casing 10 through the loop pipe 60 and the gas discharge pipe (DP) Compressor noise may be caused, but when the sliding member 100 made of a coil mass is inserted into the outer circumferential surface of the gas discharge pipe DP as in the present invention, when the gas discharge pipe DP vibrates in the left and right directions in the drawing. Vibration is attenuated by friction with the sliding member 100 in contact with the sliding member 100, which may significantly reduce vibration and noise of the compressor.

또, 미끄럼부재(100)가 코일질량체으로 형성됨에 따라 이 미끄럼부재(100)가 압축기의 진동에 따라 함께 움직이면서 선재 간 마찰을 일으키고 이 마찰에 의해 압축기 진동을 더욱 효과적으로 감쇄시킬 수 있다.In addition, as the sliding member 100 is formed as a coil mass, the sliding member 100 moves together with the vibration of the compressor, causing friction between the wire rods, and the friction of the compressor can be more effectively attenuated by the friction.

본 발명에 의한 왕복동식 압축기의 소음 저감 장치는, 가스토출관의 외주면에 미끄럼부재를 접촉하도록 삽입함으로써, 가스토출관을 통해 압축기구부에서 케이싱으로 전달되는 진동을 마찰에 의해 감쇄할 수 있고 이를 통해 압축기의 진동 소음을 효과적으로 줄일 수 있다.Noise reduction device of the reciprocating compressor according to the present invention, by inserting the sliding member in contact with the outer peripheral surface of the gas discharge pipe, it is possible to attenuate the vibration transmitted to the casing from the compression mechanism through the gas discharge pipe by friction and thereby The vibration noise of the compressor can be effectively reduced.
