3,6 : 팽창형 챔버 7 : 공명자3,6: inflatable chamber 7: resonator
본 고안은 왕복동식 압축기의 프레임 구조에 관한 것으로, 좀더 구체적으로는 프레임을 상, 하로 분리시키고 각 프레임에 팽창형 챔버(Chamber)의 공명자(Reson-ator)등의 홈을 형성하여 압축기 구동시에 발생하는 소음을 감소시킬 수 있게한 것이다.The present invention relates to a frame structure of a reciprocating compressor, and more specifically, to separate the frame up and down, and to form a groove such as a resonator of an expandable chamber (Chamber) in each frame when the compressor is driven. The noise generated can be reduced.
종래에 일반적으로 사용되어온 왕복동식 압축기는 제5도와 같이 모터(10)의 구동에 의해 회전하는 크랭크축(12), 크랭크축의 회전에 의해 실린더(13)내를 이동하면서 냉매를 압축시키는 피스턴(14), 실린더의 일측에 설치된 실린더 헤드 및 밸브계(15) 크랭크축(12)과 실린더(13)를 지지하는 프레임(11), 쉘(16)의 일측에 연결된 흡입파이프(9)등으로 구성되어 있다.The reciprocating compressor generally used in the related art has a crank shaft 12 that rotates by driving the motor 10 as shown in FIG. 5, and a piston 14 that compresses a refrigerant while moving in the cylinder 13 by rotation of the crank shaft. ), The cylinder head and valve system (15) installed on one side of the cylinder, the crankshaft (12), the frame (11) for supporting the cylinder (13), and the suction pipe (9) connected to one side of the shell (16). have.
따라서 모터(10)를 구동시키면 크랭크축(12)이 회전함과 동시에 피스턴(14)이 실린더(13)내에서 왕복운동을 하게되고 흡입파이프(9)를 통해 흡입된 냉매는 실린더헤드와 밸브계(15)를 통해 압축된후 토출된다.Accordingly, when the motor 10 is driven, the crankshaft 12 rotates, and the piston 14 reciprocates in the cylinder 13, and the refrigerant sucked through the suction pipe 9 passes through the cylinder head and the valve system. It is compressed through 15 and then discharged.
상기한 왕복동식 압축기에서 구동시 발생하는 소음중 가장 큰 소음은 흡입파이프(9)를 통해 냉매가 흡입될때 냉매가스의 맥동에 의해 발생하는 소음이며, 이러한 맥동에 의한 소음을 줄이는 것이 압축기의 소음을 감소시키는 관건이 된다.Among the noises generated when the reciprocating compressor is driven is the noise generated by the pulsation of the refrigerant gas when the refrigerant is sucked through the suction pipe 9, and the noise caused by the pulsation reduces the noise of the compressor. The key to reducing.
또한 종래의 왕복동식에서는 실린더 헤드 부위에 머플러를 설치하여 상기와 같이 냉매가스의 맥동소음을 감소시키고 있다.In the conventional reciprocating type, a muffler is provided in the cylinder head portion to reduce pulsation noise of the refrigerant gas as described above.
그러나 머플러만으로 소음을 감소시키는 경우 제한된 공간면적에 제한된 크기의 머플러를 설치할 수 밖에 없기 때문에 충분한 소음 감소효과를 얻을 수 없다.However, when the noise is reduced by the muffler alone, a sufficient noise reduction effect cannot be obtained because a muffler of a limited size is installed in a limited space area.
본 고안은 실린더와 클랭크축등의 지지 고정을 위한 프레임을 이용하여 소음을 더욱 감소시킬 수 있는 장치를 제공하기 위한 것인바, 이를 첨부된 도면 제1도 내지 제4도를 참조하여 더욱 상세하게 설명하면 다음과 같다.The present invention is to provide a device that can further reduce the noise by using a frame for fixing the support such as the cylinder and the crankshaft, which will be described in more detail with reference to FIGS. Is as follows.
첨부도면 제1도 내지 제3도는 본 고안의 프레임을 도시한 사시도와 하부프레임의 평면도 및 조립 상태 단면도이다1 to 3 is a perspective view showing a frame of the present invention and a plan view and assembled state cross-sectional view of the lower frame.
프레임(1)은 상부프레임(2)과 하부프레임(5)으로 분할 형성되어 있으며, 상부프레임(2)에는 좁은 연결통로에 의해 서로 연결된 복수개의 팽창형 챔버(3) 및 냉매 가스 배출구(4)가 형성되어 있고 하부프레임(5)에는 상부 프레임과 같은 형상의 팽창형 챔버(6)와 공명자(7) 및 냉매가스 흡입구(8)가 형성되어 있다.The frame 1 is divided into an upper frame 2 and a lower frame 5, and the upper frame 2 has a plurality of expansion chambers 3 and refrigerant gas outlets 4 connected to each other by narrow connecting passages. Is formed, and the lower frame 5 is formed with an expandable chamber 6, a resonator 7, and a refrigerant gas inlet 8 having the same shape as the upper frame.
또 상기한 상, 하 프레임(2)(5)은 소정의 결합수단에 의해 결합된다.In addition, the upper and lower frames 2 and 5 are coupled by a predetermined coupling means.
제4도는 본 고안의 프레임이 설치된 왕복동식 압축기의 일부단면도로서, 하부 프레임(5)의 냉매가스 흡입구(8)에는 흡입파이프(9)가 연결되어 냉매가스는 상, 하 프레임(2)(5)에 형성된 복수개의 팽창형(3)(6)와 하부프레임(5)에 형성된 공명자(7)를 거친후 상부프레임의 냉매 가스 배출구(4)를 통해 배출되며, 냉매가스 배출구의 근접한 위치에는 종래 구조와 같은 형태의 머플러(도시는 생략함)가 설치된다.4 is a partial cross-sectional view of a reciprocating compressor provided with a frame according to the present invention, in which a suction pipe 9 is connected to a refrigerant gas inlet 8 of the lower frame 5 so that the refrigerant gas is connected to the upper and lower frames 2 and 5. After passing through the resonator (7) formed in the plurality of expansion type (3) (6) and the lower frame (5) formed in the) is discharged through the refrigerant gas outlet (4) of the upper frame, A muffler (not shown) of the same type as a conventional structure is provided.
상기와 같이된 본 고안은 압축기의 구동시 흡입파이프(9)를 통해 흡입된 냉매가 하부프레임(5)의 냉매 가스 흡입구(8)로 유입된 후, 상, 하 프레임(2)(5)에 형성된 복수개의 팽창형 챔버(3)(6)와 하부프레임(5)의 공명자(7)를 거쳐 냉매가스 배출구(4)를 통해 배출되므로 각 팽창형 챔버와 공명자를 거치는 동안 소음이 크게 줄어들게 되고 또 냉매가스 배출구 부근에 설치된 머플러에 의해 2차적으로 소음이 감소된다.According to the present invention as described above, the refrigerant sucked through the suction pipe 9 when the compressor is driven flows into the refrigerant gas inlet 8 of the lower frame 5, and then the upper and lower frames 2 and 5. It is discharged through the refrigerant gas outlet (4) through the resonator (7) of the plurality of expandable chamber (3) (6) and the lower frame (5) formed, the noise is greatly reduced during each of the expansion chamber and the resonator In addition, noise is secondarily reduced by the muffler provided near the refrigerant gas outlet.
이상에서와 같이 본 고안은 부품의 지지역할을 수행하는 프레임을 이용하여 압축기의 구동소음을 현저하게 감소시킬 수 있는 효과가 있다.As described above, the present invention has an effect of significantly reducing the driving noise of the compressor by using a frame that performs the localization of parts.
