Description

밀폐형 왕복동식 압축기Hermetic reciprocating compressor

본 발명은 밀폐형 왕복동식 압축기에 관한 것이다.The present invention relates to a hermetic reciprocating compressor.

종래의 밀폐형 왕복동식 압축기 특히, 냉장고에 채용되는 밀폐형 왕복동식 압축기에서는, 실린더(127)와 실린더헤드(139) 사이에, 도 6에 도시된 바와 같이, 냉매를 흡입 및 토출하는 냉매흡입공(121) 및 냉매토출공(123)을 가지는 밸브시트부재(125)가 개재되어 있고, 이 밸브시트부재(125)의 양면에 실린더(127) 내의 피스톤(128)의 왕복운동에 기인한 밸브시트부재(125) 양측의 압력차에 의해 냉매흡입공(121) 및 냉매토출공(123)을 각각 개폐하는 흡입밸브리이드(131)와 토출밸브리이드(133)가 배치된다. 토출밸브리이드(133)의 상면에는 토출밸브리이드(133)의 개방방향으로의 이격거리를 한정시키는 밸브스톱(135)이 위치하고 이 밸브스톱(135)의 상면에도 밸브스톱(135)을 지지하는 키퍼(137)가 순차적으로 배치된다. 밸브시트부재(125)의 일면에는 흡입밸브리이드(131)가 고정되고, 타면에는 토출밸브리이드(133), 밸브스톱(135), 키퍼(137)가 순차적으로 안착될 수 있는 그루브가 형성되어 있고 이것들이 실리더헤드(139)에 의해 가압되어 일체로 고정된다.In a conventional hermetic reciprocating compressor, particularly a hermetic reciprocating compressor employed in a refrigerator, a refrigerant suction hole 121 which sucks and discharges a refrigerant between the cylinder 127 and the cylinder head 139, as shown in FIG. And a valve seat member 125 having a coolant discharge hole 123, and the valve seat member due to the reciprocating motion of the piston 128 in the cylinder 127 on both sides of the valve seat member 125 ( 125, the suction valve lead 131 and the discharge valve lead 133 are respectively disposed to open and close the refrigerant suction hole 121 and the refrigerant discharge hole 123 by the pressure difference between both sides. A valve stop 135 is provided on the upper surface of the discharge valve lead 133 to limit the separation distance in the opening direction of the discharge valve lead 133, and a keeper supporting the valve stop 135 on the upper surface of the valve stop 135. 137 are sequentially arranged. The suction valve lead 131 is fixed to one surface of the valve seat member 125, and a groove on which the discharge valve lead 133, the valve stop 135, and the keeper 137 may be sequentially mounted is formed on the other surface of the valve seat member 125. These are pressed by the cylinder head 139 and fixed integrally.

이러한 구성에 의해서, 토출시에는 피스톤(128)이 상사점(B)으로 이동함으로써, 압축된 냉매가 냉매토출공(123)을 관통하여 토출밸브리이드(133)를 개방방향으로 이격하면서, 토출밸브리이드(133)와 접촉하고 있는 밸브스톱(135)도 일체로 이격된다. 이때 토출밸브리이드(133)는 밸브스톱(135)과 밸브스톱(135)은 키퍼(137)면과 각각 선접촉하여 마찰이격되면서 토출밸브리이드(133)의 이격거리를 한정시킨다.With this configuration, the piston 128 moves to the top dead center B at the time of discharge, so that the compressed refrigerant passes through the refrigerant discharge hole 123 and is spaced apart from the discharge valve lead 133 in the open direction to discharge the discharge valve. The valve stop 135 in contact with the lead 133 is also integrally spaced apart. At this time, the discharge valve lead 133, the valve stop 135 and the valve stop 135 is in line contact with the keeper 137 surface, respectively, while frictionally spaced to limit the separation distance of the discharge valve lead 133.

그런데, 토출밸브리이드(133)는 냉매토출공(123)의 연부영역과 접촉된 상태에서, 토출시에 개방방향으로 이격되도록 되어 있다. 따라서, 상사점(B)에서의 피스톤(128)과 냉매토출공(123)의 실린더헤드(139)측 연부 사이의 공간 즉, 극간체적 내에는 토출과정에서 실린더 (127)밖으로 빠져나가지 못한 압축된 냉매가 냉매흡입시에 다시 역류하여 재압축되는 현상이 발생하게 된다. 이는 압축기의 충전효율의 저하 혹은 전체효율을 저하시키는 요인으로 작용하게 된다. 또한, 토출밸브리이드(133)와 밸브스톱(135)은 상호 면접촉하고 있기 때문에, 냉매토출시 토출밸브리이드(133)와 밸브스톱(135)이 선접촉되어 마찰하면서 이격되어 고주파의 소음을 발생시키게 된다.By the way, the discharge valve lead 133 is spaced apart in the opening direction at the time of discharge, in contact with the edge region of the refrigerant discharge hole 123. Therefore, in the space between the piston 128 at the top dead center B and the edge of the cylinder head 139 side of the refrigerant discharge hole 123, that is, the interstitial volume, the compressed air cannot escape out of the cylinder 127 during the discharging process. The refrigerant flows again when the refrigerant is sucked back to recompress. This acts as a factor of lowering the charging efficiency of the compressor or lowering the overall efficiency. In addition, since the discharge valve lead 133 and the valve stop 135 are in surface contact with each other, when the refrigerant is discharged, the discharge valve lead 133 and the valve stop 135 are in line contact with each other and frictionally spaced to generate high frequency noise. Let's go.

따라서, 본 발명의 목적은 극간체적을 감소시켜 냉매의 재압축을 역류를 최소화하고 밸브의 선접촉을 배제하여 실린더내부의 충전효율 및 과압축을 개선하고 고주파소음을 저감시킨 밀폐형 왕복동식 압축기를 제공하는 것이다.Accordingly, an object of the present invention is to provide a hermetic reciprocating compressor which reduces inter-volume volume, minimizes recompression of refrigerant, minimizes backflow, eliminates line contact of valves, improves filling efficiency and overcompression in the cylinder, and reduces high frequency noise. will be.

이하에서 도면을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 밀폐형 왕복동식 압축기를 실린더의 측면에서 본 단면도이고, 도 2는 실린더헤드 측에서 본 측면도이다. 이 도면들에서 도시된 바와 같이, 외부케이싱(1) 내부에 수용된 밀폐형 왕복동식 압축기의 본체(3)의 하부영역에는 내부에서 왕복동하는 피스톤(28)을 가지고 흡입된 냉매가스를 압축하는 실린더(27)가 설치되어 있다. 실린더(27)에는 냉매흡입관(5)을 통해 외부케이싱(1)의 외부로부터 유동해 온 냉매를 수용하여 실린더(27)로 공급하는 냉매머플러(7)가 설치되어 있다.1 is a cross-sectional view of a hermetic reciprocating compressor according to the present invention from the side of a cylinder, and FIG. 2 is a side view of the cylinder head. As shown in these figures, the lower region of the main body 3 of the hermetic reciprocating compressor housed inside the outer casing 1 has a cylinder 28 for compressing the refrigerant gas sucked with the piston 28 reciprocating therein. ) Is installed. The cylinder 27 is provided with a refrigerant muffler 7 which receives the refrigerant flowing from the outside of the outer casing 1 through the refrigerant suction pipe 5 and supplies it to the cylinder 27.

도 3은 실린더헤드(27)부의 확대단면도이다. 실린더(27)와 실린더헤드(39) 사이에는 냉매를 흡입 및 토출하는 냉매흡입공(21) 및 냉매토출공(23)이 형성된 밸브시트부재(25)가 개재되어 있다. 밸브시트부재(25)의 피스톤(28)측 면에는, 판상의 흡입밸브리이드(31)가 설치되어 냉매흡입공(21)을 개폐할 수 있도록 되어 있다.3 is an enlarged cross-sectional view of the cylinder head 27 portion. A valve seat member 25 having a refrigerant suction hole 21 and a refrigerant discharge hole 23 for sucking and discharging the refrigerant is interposed between the cylinder 27 and the cylinder head 39. On the piston 28 side surface of the valve seat member 25, a plate-shaped suction valve lead 31 is provided so that the refrigerant suction hole 21 can be opened and closed.

밸브시트부재(25)의 실린더헤드(39)측 면에는, 냉매토출공(23)에 접리가능하게 설치되어, 냉매토출공(23)의 연부에 접촉하는 구면접촉부를 가지고 냉매토출공(23)을 개폐하는 구형밸브체(42)가 마련되어 있다. 이 구형밸브체(42)는 탄성재질의 판재형상을 갖는 가이드 플레이트(45)에 의해 접촉지지되어 냉매토출공(23)에 접리안내되도록 되어 있다. 가이드 플레이트(45)는 그 일측이, 도 4에 도시된 바와 같이, 냉매토출공(23)으로부터 이격된 실린더헤드(39)의 연부가 밸브시트부재(25)를 가압하는 위치에 고정되고, 타측자유단에 형성된 수용부에 구형밸브체(42)가 일부 삽입되어, 구형밸브체(42)가 냉매토출공(23)에 접리되는 것을 안내하도록 되어 있다. 냉매토출공(23)의 구형밸브체(42)와 접촉하는 연부는, 도 5에 도시된 바와 같이, 구형밸브체(42)의 구면과 대응접촉할 수 있도록 구면형상으로 이루어져 있다.The cylinder head 39 side surface of the valve seat member 25 is provided to be foldable in the refrigerant discharge hole 23, and has a spherical contact portion in contact with the edge of the refrigerant discharge hole 23. The spherical valve body 42 which opens and closes is provided. The spherical valve body 42 is brought into contact with the guide plate 45 having a plate shape of elastic material to be guided to the refrigerant discharge hole 23. As shown in FIG. 4, one side of the guide plate 45 is fixed to a position where the edge of the cylinder head 39 spaced apart from the refrigerant discharge hole 23 presses the valve seat member 25, and the other side thereof. A part of the spherical valve body 42 is inserted into the accommodating portion formed at the free end, and the spherical valve body 42 is guided to be folded into the refrigerant discharge hole 23. The edge contacting the spherical valve body 42 of the coolant discharge hole 23 has a spherical shape so as to be in contact with the spherical surface of the spherical valve body 42, as shown in FIG.

가이드 플레이트(45)에 지지된 구형밸브체(42)의 도면상 상측에는 구형밸브체(42)의 개방방향으로의 이격거리를 한정하는 밸브스톱(35)이 구형밸브체(42)와 점접촉되도록 설치되어 있다. 이 밸브스톱(35)의 도면상 상측에는 키퍼(37)가 구형밸브체(42) 및 밸브스톱(35)으로부터 이격되어 브릿지 형상으로 설치되어 있다.On the upper side of the drawing of the spherical valve body 42 supported by the guide plate 45, a valve stop 35 which defines a separation distance in the opening direction of the spherical valve body 42 is in point contact with the spherical valve body 42. It is installed if possible. Above the drawing of the valve stop 35, a keeper 37 is provided in a bridge shape spaced apart from the spherical valve body 42 and the valve stop 35.

이러한 구성에 의해서, 냉매흡입관(5)을 통해 머플러(7)로 유입된 냉매는 실린더헤드(39)로 유동하여 밸브시트부재(25)에 형성된 냉매흡입공(21)을 통해 실린더(27) 내부로 흡입된다. 흡입된 냉매는 피스톤(28)이 실린더(27) 내부의 하사점과 상사점(A) 사이를 왕복동하여 압축되고, 압축된 냉매는 냉매토출공(23)을 통해 실린더(27) 외부로 토출된다. 이 때, 냉매토출공(23)을 관통한 냉매가 가이드플레이트(45)에 의해 지지되는 구형밸브체(42)를 개방방향으로 가압하면, 구형밸브체(42)와 점접촉하고 있는 밸브스톱(35)도 밸브시트부재(25)로부터 일체로 이격된다. 밸브스톱(35)은 키퍼(37)면과 선접촉하여 이격이 제한되며, 이에 의해 구형밸브체(42)의 이격거리도 한정된다. 이에 따라, 토출밸브(41)의 구형밸브체(42)이 밸브스톱(35)과 점접촉하면서 이격되므로, 고주파 소음발생이 저감된다.By this configuration, the refrigerant introduced into the muffler 7 through the refrigerant suction pipe 5 flows into the cylinder head 39 to form the inside of the cylinder 27 through the refrigerant suction hole 21 formed in the valve seat member 25. Is inhaled. The sucked refrigerant is compressed by reciprocating the piston 28 between the bottom dead center and the top dead center A inside the cylinder 27, and the compressed refrigerant is discharged to the outside of the cylinder 27 through the refrigerant discharge hole 23. . At this time, when the refrigerant passing through the refrigerant discharge hole 23 presses the spherical valve body 42 supported by the guide plate 45 in the opening direction, the valve stop is in point contact with the spherical valve body 42 ( 35 is also integrally spaced from the valve seat member 25. The valve stop 35 is in line contact with the keeper 37 surface to limit the separation, thereby limiting the separation distance of the spherical valve body 42. Thereby, since the spherical valve body 42 of the discharge valve 41 is spaced apart by the point contact with the valve stop 35, high frequency noise generation is reduced.

압축된 냉매가 실린더(27) 외부로 토출되면, 냉매흡입공(21)을 통하여 새로운 냉매가 실린더(27) 내부로 흡입된다. 이 때, 토출밸브(41)의 구형밸브체(42)의 구면과 냉매토출공(23) 내부로 함몰형성된 구면형상의 연부에 접촉하여 냉매토출공의 내부공간을 점유하면서 폐쇄하게 된다. 이에 따라, 실린더(27) 내부의 극간체적이 감소되어, 냉매토출공(23)에 압축된 냉매가 잔류하지 않게 되어, 냉매흡입공(21)으로 흡입되는 냉매의 충전효율이 좋아지게 된다. 그래서, 압축기의 전체효율도 좋아진다.When the compressed refrigerant is discharged to the outside of the cylinder 27, new refrigerant is sucked into the cylinder 27 through the refrigerant suction hole 21. At this time, the spherical surface of the spherical valve body 42 of the discharge valve 41 and the spherical-shaped edge recessed into the refrigerant discharge hole 23 are closed to occupy the internal space of the refrigerant discharge hole. Accordingly, the intervolume volume inside the cylinder 27 is reduced, so that the compressed refrigerant does not remain in the refrigerant discharge hole 23, and the charging efficiency of the refrigerant sucked into the refrigerant suction hole 21 is improved. Thus, the overall efficiency of the compressor is also improved.

이상 설명한 바와 같이, 본 발명에 따르면, 극간체적을 감소시켜 냉매의 재압축을 역류를 최소화하고 밸브의 선접촉을 배제하여 실린더내부의 충전효율 및 과압축을 개선하고 고주파소음을 저감시킨 밀폐형 왕복동식 압축기가 제공된다.As described above, according to the present invention, the hermetic reciprocating compressor which reduces the intervolume volume, minimizes the recompression of the refrigerant, minimizes the reverse flow, eliminates the line contact of the valve, improves the filling efficiency and overcompression inside the cylinder, and reduces the high frequency noise. Is provided.
