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.

본 발명의 목적을 달성하기 위하여, 가동자와 이 가동자에 결합한 피스톤이 직선으로 왕복운동을 하면서 냉매가스를 흡입 압축하여 토출하는 압축기본체를 수용하는 케이싱과, 케이싱의 일측에 관통 결합하고 탄성을 가지는 루프파이프에 의해 상기한 압축기본체의 토출측과 연결되어 그 압축기본체에서 토출되는 냉매가스를 냉동사이클장치의 냉매관으로 전달하는 가스토출관과, 케이싱의 안쪽 또는 바깥쪽중에서 적어도 어느 한쪽 가스토출관의 외주면에 고정하여 진동을 흡수하는 댐핑부재를 포함한 왕복동식 압축기의 소음 저감 장치를 제공한다.In order to achieve the object of the present invention, a casing for accommodating the mover and the piston body coupled to the mover and the compressor main body for sucking and compressing and discharging the refrigerant gas while linearly reciprocating, and through the coupling to one side of the casing and elasticity The gas pipe is connected to the discharge side of the compressor main body by a loop pipe, and transfers the refrigerant gas discharged from the compressor main body to the refrigerant pipe of the refrigeration cycle apparatus, and at least one gas discharge tube inside or outside the casing. It provides a noise reduction device of the reciprocating compressor including a damping member to be fixed to the outer peripheral surface of the absorbing vibration.

이하, 본 발명에 의한 왕복동식 압축기의 소음 저감 장치를 첨부도면에 도시한 일실시예에 의거하여 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the noise reduction apparatus of the reciprocating compressor by this invention is demonstrated in detail based on one Example shown in an accompanying drawing.

이에 도시한 바와 같이 본 발명 왕복동식 압축기는, 가스흡입관(SP)과 가스토출관(DP)을 연통 설치하는 케이싱(10)과, 케이싱(10)의 내부에 탄력적으로 설치하는 프레임 유니트(20)와, 프레임 유니트(20)에 설치하여 가동자(33)가 직선으로 왕복운동을 하는 왕복동식 모터(30)와, 왕복동식 모터(30)의 가동자(33)에 피스톤(42)을 결합하여 이 피스톤(42)이 실린더(41)의 내부에서 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)와, 케이싱(10)과 가스토출관(DP)의 연결부위에 고정 설치하여 상기한 가스토출관(DP)을 타고 전달되는 진동을 흡수하는 댐핑부재(100)를 포함한다.As shown in the drawing, the reciprocating compressor of the present invention includes a casing 10 for communicating the gas suction pipe SP and the gas discharge pipe DP, and a frame unit 20 elastically installed in the casing 10. 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. Compression unit 40 for sucking and compressing and discharging refrigerant gas while the piston 42 reciprocates linearly inside cylinder 41, and frame unit 20 to induce a resonant movement of compression unit 40. And the resonant spring unit 50 installed between the compression unit 40 and the casing 10 and the connection part of the gas discharge pipe DP to fix the vibration transmitted through the gas discharge pipe DP. It includes a damping member 100 to absorb.

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.

댐핑부재(100)는 도 4에서와 같이 케이싱(10)의 내외 양측에 위치하도록 가스토출관(DP)에 삽입 고정하는 것으로, 케이싱(10)에 대향하는 일측면은 각각 그 케이싱(10)의 내벽면과 외벽면에 밀착하여 고정하는 것이 진동을 흡수하는데 보다 바람직하다.The damping member 100 is inserted into and fixed to the gas discharge pipe DP so as to be positioned at both inside and outside sides of the casing 10, as shown in FIG. 4. It is more preferable to absorb the vibration in close contact with the inner wall surface and the outer wall surface.

이를 위해, 댐핑부재(100)는 도 5에서와 같이 시링(C-ring) 모양으로 형성하여 가스토출관(DP)을 케이싱(10)에 용접 결합한 후 각각 후조립하거나 또는 도 6에서와 같이 시(C)형 클램프 모양으로 형성하여 역시 가스토출관(DP)을 케이싱(10)에 용접 결합한 후 각각 후조립할 수 있다.To this end, the damping member 100 is formed in a C-ring shape as shown in FIG. 5 to weld the gas discharge pipe DP to the casing 10, and then post-assemble each or as shown in FIG. 6. Formed in the form of the (C) clamp can also be post-assembled after the gas discharge pipe (DP) is also welded to the casing (10).

또, 댐핑부재(100)는 가급적이면 내열성 플라스틱과 같은 연성재질로 형성하는 것이 진동을 흡수하는데 바람직하다.In addition, the damping member 100 is preferably formed of a soft material such as heat-resistant plastic to absorb 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)과 케이싱(10)의 연결부위에 별도의 댐핑부재(100)를 삽입하는 경우에는 상기한 진동이 댐핑부재(100)에 흡수됨에 따라 왕복동식 모터(30)와 압축 유니트(40)에서 발생하여 루프파이프(60)와 가스토출관(DP)을 통해 케이싱(10)으로 전달되는 진동을 상쇄할 수 있고 이를 통해 압축기의 진동과 소음을 효과적으로 줄일 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 the vibration is absorbed by the damping member 100 when a separate damping member 100 is inserted into the connection portion of the gas discharge pipe DP and the casing 10 as in the present invention. The vibration generated in the reciprocating motor 30 and the compression unit 40 to be transmitted to the casing 10 through the loop pipe 60 and the gas discharge pipe (DP) to offset the vibration of the compressor through Noise can be effectively reduced.

또, 댐핑부재(100)와 케이싱(10)을 밀착 결합함에 따라 가스토출관(DP)의 진동시 상기한 댐핑부재(100)가 미세하게 움직이면서 케이싱(10)과 마찰을 일으켜 진동과 소음을 더욱 효과적으로 줄일 수 있다.In addition, as the damping member 100 and the casing 10 are closely coupled, the damping member 100 moves finely during vibration of the gas discharge pipe DP, causing friction with the casing 10 to further generate vibration and noise. Can be effectively reduced.

본 발명에 의한 왕복동식 압축기의 소음 저감 장치는, 케이싱과 가스토출관의 연결부위에 진동을 흡수하는 댐핑부재를 설치함으로써, 가스토출관을 통해 압축기구부에서 케이싱으로 전달되는 진동을 흡수하여 상쇄할 수 있고 이를 통해 압축기의 진동 소음을 효과적으로 줄일 수 있다.The noise reduction device of the reciprocating compressor according to the present invention is provided with a damping member for absorbing vibration at the connection portion between the casing and the gas discharge pipe, thereby absorbing and canceling the vibration transmitted from the compression mechanism to the casing through the gas discharge pipe. This can effectively reduce the vibration noise of the compressor.
