Abstract

왕복동식 압축기의 토출밸브 소음 감소장치에 관하여 개시되어 있다.Disclosed is a discharge valve noise reduction device of a reciprocating compressor.

종래의 압축기는 토출밸브(6)와 밸브 플레이트 시트면(5d)이 직접 접촉되어 실린더내의 토출 가스 압력에 따라 토출밸브(6)가 개폐될때 마찰에 의한 고주파 소음이 발생되었으나, 본 고안에 의한 소음 감소장치는 토출밸브(6)와 밸브 플레이트(5)의 사이에 소음감쇄부(D)를 삽입함으로써 토출밸브(6)가 개폐시에 완충작용을 하여 소음을 줄일 수 있는 이점이 있다.In the conventional compressor, when the discharge valve 6 and the valve plate seat surface 5d are in direct contact and the discharge valve 6 is opened and closed according to the discharge gas pressure in the cylinder, high frequency noise is generated due to friction. The reducing device has an advantage of reducing noise by inserting a noise damping unit D between the discharge valve 6 and the valve plate 5 when the discharge valve 6 is opened and closed.

본 고안은 냉장고용 압축기에 관한 것으로서, 상세하게는 압축기의 토출밸브에서 발생하는 소음을 감소시키는 장치에 관한 것이다.The present invention relates to a compressor for a refrigerator, and more particularly, to an apparatus for reducing noise generated in a discharge valve of a compressor.

일반적으로 냉장고의 소음은 압축기의 토출밸브에서 비롯되는 바, 종래의 압축기를 참조하여 이를 설명하면 아래와 같다.In general, the noise of the refrigerator comes from the discharge valve of the compressor, which will be described below with reference to a conventional compressor.

제1도 내지 제3도는 종래의 냉장고용 압축기를 나타낸다. 제1도는 종래 왕복동식 압축기의 구조, 제2도는 상기 제1도의 밸브 및 실린더 헤드부를 분해한 사시도, 제3도는 상기 제2도의 밸브 플레이트부의 조립단면도를 각각 나타낸다. 제2도에서 보는 바와 같이, 흡입밸브(4)는 밸브 플레이트(5)와 접촉되고 토출밸브(6)는 밸브 스토퍼(Stopper, 7) 및 밸브 키퍼(Keeper, 8)에 의해 밸브 플레이트(5)에 고정된다. 또한 헤드 가스켓(9) 및 실린더 헤드(10)는 밸브 플레이트(5)와 함께 헤드볼트(12)로 조여져 실린더 블럭(1)에 고정되는 구조로 되어 있다.1 to 3 show a conventional compressor for a refrigerator. 1 is a structure of a conventional reciprocating compressor, FIG. 2 is an exploded perspective view of the valve and cylinder head of FIG. 1, and FIG. 3 is an assembled sectional view of the valve plate of FIG. As shown in FIG. 2, the intake valve 4 is in contact with the valve plate 5 and the discharge valve 6 is connected to the valve plate 5 by the valve stopper 7 and the valve keeper 8. Is fixed to. In addition, the head gasket 9 and the cylinder head 10 are tightened by the head bolt 12 together with the valve plate 5 to be fixed to the cylinder block 1.

종래 압축기의 동작과정에 있어서, 냉매 가스는 피스톤(15)의 운동에 의해 흡입튜브(13)를 지나 실린더 헤드(10) 및 밸브 플레이트 흡입구(5a)를 통과하여 실린더 블럭(1)내의 실린더로 흡입된다. 실린더내에서 압축되 가스는 다시 밸브 플레이트의 토출구(5b) 및 실린더 헤드(10)의 토출방을 거쳐 밸브 플레이트의 패스 홀(Pass hole, 5c)과 실린더 블럭(1)의 패스 홀(1a)로 들어간 후, 라인(Line) 토출튜브(16)를 지나 토출튜브(17)로 배출된다. 흡입밸브(4)는 흡입 리드부(4a)가 형성되어 가스 흡입시 실린더 쪽으로 여닫히는 작용을 하고, 토출밸브(6)는 실린더내에서 압축된 토출가스의 압력에 의해 개폐된다. 제3도를 참조하여 상기 토출밸브(6)의 작동을 더 상세히 설명하면, 토출밸브(6)가 토출가스의 압력에 의해 개폐될때 토출밸브(6)는 밸브 플레이트 시트면(5d)과 단속적인 접촉이 이루어지는데 이때 토출밸브와 밸브 플레이트는 통상 금속 재질로 이루어져 있으므로 마찰 소음이 발생한다. 즉, 가스 토출시 토출밸브(6)와 밸브 플레이트 시트면(5d)이 오일(Oil)로 점착된 상태에서 토출밸브(6)가 열리기 때문에 소음이 발생하고, 토출이 끝난 후 가스 흡입시 토출밸브(6)가 닫힐 때에도 밸브 플레이트 시트면(5d)과 부딪히게 되므로 소음이 발생하는데 이러한 소음은 압축기 소음의 주원인이 되는 고주파 소음(3.5kHz 내지 4kHz)으로 문제가 되고 있다.In the operation of the conventional compressor, the refrigerant gas is sucked into the cylinder in the cylinder block 1 through the cylinder head 10 and the valve plate suction port 5a through the suction tube 13 by the movement of the piston 15. do. The gas compressed in the cylinder is again passed through the discharge port 5b of the valve plate and the discharge chamber of the cylinder head 10 to the pass hole 5c of the valve plate and the pass hole 1a of the cylinder block 1. After entering, it passes through the line discharge tube 16 and is discharged to the discharge tube 17. The suction valve 4 has a suction lead 4a formed to open and close to the cylinder when gas is sucked, and the discharge valve 6 is opened and closed by the pressure of the discharge gas compressed in the cylinder. Referring to FIG. 3, the operation of the discharge valve 6 will be described in more detail. When the discharge valve 6 is opened and closed by the pressure of the discharge gas, the discharge valve 6 is intermittent with the valve plate seat surface 5d. In this case, since the discharge valve and the valve plate are usually made of metal, friction noise is generated. That is, since the discharge valve 6 is opened while the discharge valve 6 and the valve plate seat surface 5d are adhered with oil at the time of gas discharge, noise is generated. Even when (6) is closed, noise is generated because it hits the valve plate seat surface 5d. This noise is a problem due to high frequency noise (3.5 kHz to 4 kHz) which is the main cause of the compressor noise.

본 고안은 상기와 같은 문제점을 개선하고자 창안된 것으로, 압축기 소음의 주원인이 되고 있은 고주파 소음을 감소시키는 소음 감소장치를 제공하여 왕복동식 압축기의 소음을 감소시키는데 그 목적이 있다.The present invention was devised to improve the above problems, and an object of the present invention is to provide a noise reduction device for reducing high frequency noise, which is the main cause of the compressor noise, to reduce the noise of the reciprocating compressor.

상기와 같은 목적을 달성하기 위하여 본 고안에 따른 왕복동식 압축기의 소음 감소장치는, 토출구를 가진 밸브 플레이트와 그 밸브 플레이트의 토출구에 단속적으로 결합되는 토출밸브를 포함하는 압축기에 있어서, 상기 토출밸브와 밸브 플레이트의 시트면 사이에 소음감쇄부를 가진 것을 특징으로 한다.In order to achieve the above object, a noise reduction device of a reciprocating compressor according to the present invention includes a valve plate having a discharge port and a discharge valve intermittently coupled to the discharge port of the valve plate, wherein the discharge valve and It characterized in that it has a noise reduction portion between the seat surface of the valve plate.

제4도는 본 고안에 따른 소음감쇄부(D)의 사시도(a) 및 그 소음감쇄부(D)를 결합시킨 밸브 플레이트부의 조립 단면도(b)이다. 도시한 바와 같이, 토출구(5b)는 부분의 밸브 플레이트(5)와 토출밸브(6)사이에 소음을 감소시킬 수 있는 소음감쇄부(D)를 삽입한다. 즉, 종래 압축기의 토출밸브(6) 개폐과정에 있어서는 토출밸브(6)가 밸브 플레이트(5)와 직접적으로 접촉함으로써 소음이 발생하였으나 본 고안에 따라 완충작용을 하는 감쇄부를 삽입하여 토출밸브(6)가 소음감쇄부(D)와 단속적으로 접촉되게 함으로써 마찰소음이 감소된다.Figure 4 is a perspective view (a) of the noise damping portion (D) according to the present invention and the assembled cross-sectional view (b) of the valve plate portion combined with the noise damping portion (D). As shown, the discharge port 5b inserts a noise attenuation portion D capable of reducing noise between the valve plate 5 and the discharge valve 6 of the portion. That is, in the opening and closing process of the discharge valve 6 of the conventional compressor, noise is generated by the discharge valve 6 directly contacting the valve plate 5, but according to the present invention, the damping part having a buffering function is inserted and the discharge valve 6 is inserted. ) Is brought into intermittent contact with the noise attenuation portion D, thereby reducing the friction noise.

덧붙여, 소음감쇄부(D)는 그 외경에 수나사를 형성하고 밸브 플레이트(5)의 토출구(5b)의 내경에 암나사를 형성함으로써 상호 나사결합되는 것이 바람직하다.In addition, it is preferable that the noise attenuating portion D is mutually screwed by forming a male screw at the outer diameter and a female screw at the inner diameter of the discharge port 5b of the valve plate 5.

본 고안에 따른 소음감쇄부(D)의 재료는 토출밸브(6)의 단속적인 마찰을 완화시킬 수 있는데 적합한 재료가 사용될 수 있으나, 바람직하게는 테프론 플라스틱 재질이 사용된다.The material of the noise damping unit (D) according to the present invention can be used a suitable material to alleviate the intermittent friction of the discharge valve (6), preferably Teflon plastic material is used.

상술한 바와 같이 본 고안에 의하면, 토출밸브(6)와 밸브 플레이트 시트면(5d)의 접촉에 있어서 토출밸브 개폐로 인한 고주파 소음을 줄임으로써 저소음 왕복동식 압축기를 제공할 수 있는 이점이 있다.According to the present invention as described above, there is an advantage that a low noise reciprocating compressor can be provided by reducing the high frequency noise due to opening and closing the discharge valve in contact between the discharge valve 6 and the valve plate seat surface 5d.
