Description

밀폐형 압축기의 압력파이프 진동저감장치Pressure Pipe Vibration Reduction Device for Hermetic Compressor

본 발명은 밀폐형 압축기에 관한 것으로, 더욱 상세하게는 고압으로 압축된 냉매의 토출소음을 최소로 저감시키기 위한 밀폐형 압축기의 토출소음저감장치에 관한 것이다.The present invention relates to a hermetic compressor, and more particularly, to a discharge noise reduction device of a hermetic compressor for minimizing the discharge noise of the refrigerant compressed to high pressure.

도 1에는 종래 기술에 의한 커넥팅로드 방식의 밀폐형 압축기의 내부 구성이 도시되어 있다.Figure 1 shows the internal configuration of a hermetic compressor of the connecting rod method according to the prior art.

이에 따르면, 상부용기(1t)와 하부용기(1b)로 이루어지는 밀폐용기(1)가 구비되고, 상기 밀폐용기(1)의 내부에는 프레임(2)이 지지되어 있다. 상기 프레임(2)에는 고정자(3)가 고정되어 있고, 이와 같은 프레임(2)은 스프링(2S)에 의해 밀폐용기(1) 내부에 지지되어 있다.According to this, the sealed container 1 which consists of the upper container 1t and the lower container 1b is provided, and the frame 2 is supported inside the sealed container 1. The stator 3 is fixed to the frame 2, and the frame 2 is supported inside the sealed container 1 by a spring 2S.

그리고, 상기 프레임(2)의 중앙을 관통하여서는 크랭크축(5)이 설치되어 있다. 상기 크랭크축(5)에는 회전자(4)가 일체로 설치되어 상기 고정자(3)와의 전자기적 상호작용에 의해 상기 크랭크축(5)과 함께 회전된다.The crankshaft 5 is provided through the center of the frame 2. The crankshaft 5 is integrally provided with a rotor 4 and rotated together with the crankshaft 5 by electromagnetic interaction with the stator 3.

상기 크랭크축(5)의 상단에는 편심핀(5b)이 상기 크랭크축(5)의 회전중심에대해 편심되게 형성되어 있다. 그리고 상기 편심핀(5b)이 형성된 반대쪽에는 균형 추(5c)가 형성되어 있다. 상기 크랭크축(5)의 하단에는 하부용기(1b)이 저면에 있는 오일(L)을 크랭크축(5)에 형성되어 있는 오일유로(5a)로 빨아 올리기 위한 프로펠러(5d)가 설치되어 있다.At the upper end of the crankshaft 5, an eccentric pin 5b is eccentrically formed with respect to the center of rotation of the crankshaft 5. And the counterweight 5c is formed on the opposite side of the eccentric pin (5b) is formed. The lower end of the crankshaft 5 is provided with a propeller 5d for sucking up the oil L on the bottom of the lower container 1b into the oil flow passage 5a formed on the crankshaft 5.

한편, 내부에 압축실(6')이 구비된 실린더(6)가 상기 프레임(2)에 일체로 성형되어 있다. 그리고 상기 압축실(6')에는 피스톤(7)이 설치되어 있는데, 상기 피스톤(7)은 상기 크랭크축(5)의 편심핀(5b)과 커넥팅로드(8)로 연결되어 있다.On the other hand, the cylinder 6 provided with the compression chamber 6 'inside is integrally molded with the said frame 2. As shown in FIG. A piston 7 is installed in the compression chamber 6 ', which is connected to an eccentric pin 5b of the crankshaft 5 and a connecting rod 8.

그리고 상기 실린더(6)의 선단에는 상기 압축실(6')로 유입되고 배출되는 냉매를 제어하는 밸브어셈블리(9)가 설치된다. 상기 밸브어셈블리(9)에는 헤드커버가 장착되어 압축된 후 토출되는 냉매가 지나가는 토출방(10')을 형성하게 된다. 그리고, 도면부호 12는 냉매를 밀폐용기(1)의 내부로 전달하는 흡입파이프이고, 13은 압축된 냉매를 압축기의 외부로 토출하는 토출파이프이고, 15는 베어링이다.At the front end of the cylinder 6, a valve assembly 9 for controlling the refrigerant flowing into and out of the compression chamber 6 'is installed. The valve assembly 9 is equipped with a head cover to form a discharge chamber (10 ') through which the refrigerant discharged after being compressed. In addition, reference numeral 12 is a suction pipe for delivering the refrigerant to the inside of the sealed container 1, 13 is a discharge pipe for discharging the compressed refrigerant to the outside of the compressor, and 15 is a bearing.

한편 냉매에 의해 발생되는 소음을 감소시키기 위한 흡입머플러(11)가 상기밸브어셈블리(9)를 통해 실린더(6) 내부에 있는 압축실(6')과 연결되어 있다.Meanwhile, a suction muffler 11 for reducing noise generated by the refrigerant is connected to the compression chamber 6 'inside the cylinder 6 through the valve assembly 9.

그리고, 압축되어 토출되는 냉매의 소음을 저감시키기 위한 구성이 도2에 도시되어 있다. 즉 압축되어 토출된 냉매가 토출유로(도시되지 않음)를 통해 전달되는 토출소음부(16)가 상기 프레임(2)에 구비되어 있다. 상기 토출소음부(16)에는 토출부커버(17)가 씌워져 내부에 일정한 공간을 형성하게 된다. 상기 토출부커버 (17)는 나사(S)에 의해 상기 고정된다.And, a configuration for reducing the noise of the refrigerant discharged by compression is shown in FIG. That is, the frame 2 is provided with a discharge silencer 16 through which the compressed and discharged refrigerant is transferred through a discharge passage (not shown). The discharge noise control unit 16 is covered with a discharge unit cover 17 to form a predetermined space therein. The discharge part cover 17 is fixed by the screw (S).

상기 토출소음부(16) 내의 공간으로 전달된 냉매를 배출하기 위한 루프파이프(18)가 상기 토출부커버(17)를 관통하여 설치되어 있다. 상기 루프파이프(18)는 상기 토출부커버(17)에 용접되어 고정된다.A loop pipe 18 for discharging the refrigerant transferred to the space in the discharge noise controller 16 is provided through the discharge unit cover 17. The roof pipe 18 is fixed to the discharge part cover 17 by welding.

그러나, 상기 루프파이프(18)는 고압으로 압축된 냉매를 전달하는 역할을 하는 압력파이프이다. 따라서, 상기 루프파이프(18) 내부를 통해서는 항상 고압의 냉매가 유동된다. 그러므로 상기 루프파이프(18)에는 고압냉매에 의한 진동이 많이 발생하게 된다.However, the loop pipe 18 is a pressure pipe that serves to deliver the refrigerant compressed at high pressure. Therefore, a high pressure refrigerant always flows through the loop pipe 18. Therefore, the loop pipe 18 generates a lot of vibration by the high pressure refrigerant.

상기와 같이 진동이 많이 발생하게 되면, 상기 루프파이프(18)의 진동 상기 소음부커버(17)에도 전달된다. 하지만, 상기 루프파이프(18)와 소음부커버(17)는 용접부에 의해 연결되어 있어 루르파이프(18)와 소음부커버(17) 사이에서 진동이 차단되지 않고 전달된다. 이와 같이 진동이 차단되지 않고 루프파이프(18)와 소음부커버(17) 사이에서 전달되면 용접부가 쉽게 손상되어 진동과 소음이 심해지고 누설이 발생하는 등의 문제가 발생된다.When a lot of vibration occurs as described above, the vibration of the loop pipe 18 is also transmitted to the silencer cover (17). However, the loop pipe 18 and the silencer cover 17 are connected by the welded portion, so that the vibration is not blocked between the loupe pipe 18 and the silencer cover 17. As such, when the vibration is not blocked and transmitted between the loop pipe 18 and the silencer cover 17, the welding part is easily damaged, causing the vibration and noise to be severe and leakage.

따라서 본 발명의 목적은 상기한 바와 같은 종래의 문제점을 해결하기 위한것으로, 압력파이프와 타부품과의 연결부를 통해 전달되는 진동을 차단하는 장치를 제공하는 것이다.Therefore, an object of the present invention is to solve the conventional problems as described above, to provide a device for blocking the vibration transmitted through the connection between the pressure pipe and the other parts.

상기한 바와 같은 목적을 달성하기 위한 본 발명의 제 1 특징에 따르면, 본 발명은 압력파이프가 연결되고 내부에 압력파이프와 연통되는 연통공간을 구비하는 체결몸체와, 상기 체결몸체가 체결되어 압력파이프와 상기 연통공간을 통해 내부가연통되는 부품과의 사이에서 진동전달을 차단하는 방진수단과, 상기 채결몸체를 상기 부품에 체결하기 위한 체결나사를 포함하여 구성된다.According to a first aspect of the present invention for achieving the object as described above, the present invention is a fastening body having a communication space connected to the pressure pipe and communicate with the pressure pipe therein, the fastening body is fastened by the pressure pipe And dustproof means for blocking vibration transmission between the parts communicating with the inside through the communication space, and fastening screws for fastening the chucking body to the parts.

상기 방진수단은 상기 체결몸체의 상하면에서 상기 체결나사에 의해 상기 체결몸체 및 상기 부품에 압착된다.The dustproof means is pressed to the fastening body and the component by the fastening screw on the upper and lower surfaces of the fastening body.

이와 같은 구성에 의하면 고압의 냉매가 유동되는 압력파이프에서 발생되는 진동 전달이 차단되어 압축기 전체의 진동과 소음이 저감된다.According to such a configuration, the transmission of vibration generated in the pressure pipe through which the high-pressure refrigerant flows is blocked, thereby reducing vibration and noise of the entire compressor.

이하 상기한 바와 같은 본 발명의 바람직한 실시예를 첨부된 도면을 참고하여 상세하게 설명한다. 종래 기술의 것과 동일한 것은 동일부호를 사용하여 설명한다.Hereinafter, preferred embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings. The same as in the prior art will be described using the same reference numerals.

도 3은 본 발명에 의한 밀폐형 압축기의 압력파이프 진동저감장치의 구성을 보인 분해사시도이고, 도 4는 본 발명에 의한 밀폐형 압축기의 압력파이프 진동저감장치가 설치된 것을 보인 단면도.Figure 3 is an exploded perspective view showing the configuration of the pressure pipe vibration reducing device of the hermetic compressor according to the present invention, Figure 4 is a sectional view showing that the pressure pipe vibration reducing device of the hermetic compressor according to the present invention is installed.

도면에 도시된 바에 따르면, 체결몸체(20)의 내부에는 연통공간(21)이 형성되어 있다. 이와 같은 연통공간(21)은 상기 체결몸체(20)에 연결되는 루프파이프 (18)와 토출소음부(16)의 내부공간을 연통시켜 주는 역할을 한다. 상기 체결몸체 (20)의 일측면으로는 루프파이프(18)가 상기 연통공간(21)까지 관통하여 설치되어 있다. 이와 같은 체결몸체(20)는 상기 소음부커버(17)에 나사(S)로 장착된다.As shown in the figure, a communication space 21 is formed inside the fastening body 20. The communication space 21 serves to communicate the internal space of the loop pipe 18 and the discharge noise unit 16 connected to the fastening body 20. On one side of the fastening body 20, a loop pipe 18 penetrates to the communication space 21. Such fastening body 20 is mounted to the silencer cover 17 with a screw (S).

상기 체결몸체(20)의 상하단에는 각각 방진부재(30,30')가 설치된다. 이와 같은 방진부재(30,30')는 상기 체결몸체(20)와 소음부커버(17) 사이에서 진동이 전달되는 것을 차단하고, 누설이 발생되는 것을 막아주는 역할을 한다.The upper and lower ends of the fastening body 20 are provided with dustproof members 30 and 30 ', respectively. Such dustproof members 30 and 30 'block the transmission of vibration between the fastening body 20 and the silencer cover 17, and serve to prevent leakage.

이와 같은 방진부재(30,30')는 상기 나사(S)에 치해 압착되어 고정된다.The dustproof members 30 and 30 'are pressed against and fixed to the screw S.

즉, 상기 체결몸체(20)와 소음부커버(17) 사이에 위치된 방진부재(30')는 상기 나사(S)의 체결력에 의해 상기 소음부커버(17)와 체결몸체(20) 사이에 압착된다. 그리고, 상기 체결몸체(20)의 상단부에 구비된 방진부재(30)는 상기 나사(S)의 머리 부에 의해 상기 체결몸체(20) 상단에 압착된다. 물론 상기 나사(S)의 머리부와 방진부재(30)의 사이에 와셔와 같은 것을 게재시켜 압착할 수도 있다.That is, the dustproof member 30 'positioned between the fastening body 20 and the silencer cover 17 is disposed between the silencer cover 17 and the fastening body 20 by the fastening force of the screw S. Squeezed. In addition, the dustproof member 30 provided at the upper end of the fastening body 20 is compressed to the upper end of the fastening body 20 by the head of the screw (S). Of course, it may be compressed by placing a thing such as a washer between the head of the screw (S) and the dustproof member (30).

이하 상기와 같은 구성을 가지는 본 실시예에 의해 진동이 저감되는 것을 설Hereinafter, the vibration is reduced by the present embodiment having the configuration as described above.

명한다.Order.

압축기가 구동되면, 압축된 냉매가 상기 토출소음부(16) 내부의 공간으로 전달된다. 일단 토출소음부(16)로 전달된 냉매는 다시 상기 체결몸체(20)의 연통공간 (21)을 통해 루프파이프(18)로 전달된다. 그리고 상기 루프파이프(18)와 연결되어 있는 토출파이프(12)를 통해 압축기의 외부로 토출된다.When the compressor is driven, the compressed refrigerant is delivered to the space inside the discharge noise controller 16. The refrigerant once delivered to the discharge noise controller 16 is again transferred to the loop pipe 18 through the communication space 21 of the fastening body 20. The discharge pipe 12 is discharged to the outside of the compressor through the discharge pipe 12 connected to the loop pipe 18.

이 과정에서 상기 루프파이프(18)로 전달되는 냉매는 고압상태이므로 맥동에 의한 진동이 발생하게 된다. 하지만 이와 같은 진동이 상기 루프파이프(18)나 소음 부커버(17)에서 발생하더라도 상기 방진부재(30,30')에 흡수되어 진동이 전달되지 않게 된다. 따라서, 종래에 비해 발생되는 진동이나 소음이 현저하게 줄어들게 된다.In this process, since the refrigerant delivered to the roof pipe 18 is in a high pressure state, vibration caused by pulsation is generated. However, even if the vibration is generated in the roof pipe 18 or the noise sub-cover 17, the vibration is not absorbed by the dustproof members 30 and 30 '. Therefore, the vibration and noise generated compared to the prior art is significantly reduced.

그리고, 상기 방진부재(30,30')에 의해 진동이 흡수되어 루프파이프(18)와 소음부커버(17) 사이에서 진동이 전달되지 않게 되면, 상대적으로 상기 루프파이프 (18)와 소음부커버(17) 사이의 연격부 파손현상이 줄어들게 된다. 또한, 상기 방진부재(30,30')는 냉매의 누설을 방지하는 역할도 하게 된다.When the vibration is absorbed by the dustproof members 30 and 30 'so that the vibration is not transmitted between the roof pipe 18 and the silencer cover 17, the loop pipe 18 and the noise cover are relatively. The breakage between the spaces between (17) is reduced. In addition, the dustproof members 30 and 30 'also serve to prevent leakage of the refrigerant.

위에서 상세히 설명한 바와 같은 본 발명에 의한 밀폐형 압축기의 압력파이프 진동저감장치는 압력파이프와 소음부커버를 연결하는 채결몸체에 방진부재를 설The pressure pipe vibration reducing device of the hermetic compressor according to the present invention as described in detail above is provided with a dustproof member on the coupling body connecting the pressure pipe and the silencer cover.

치하여 이들 사이에서 진동이 전달되는 것을 차단하였으므로 진동과 소음발생이 현저하게 줄어들고, 상기 방진부재에 의해 누설이 방지되는 효과도 기대할 수 있다.In addition, since the vibration is prevented from being transmitted between them, the vibration and noise are significantly reduced, and the effect of preventing leakage by the dustproof member can be expected.
