Description

밀폐형 왕복동식 압축기용 흡입머플러Suction Muffler for Hermetic Reciprocating Compressors

본 발명은 밀폐형 왕복동식 압축기용 흡입머플러에 관한 것이다.The present invention relates to a suction muffler for a hermetic reciprocating compressor.

냉장고 등의 냉동장치에는 증발기로부터의 기상냉매를 압축하여 고압의 냉매기체로 만들어 토출하는 압축기가 구비되어 있다. 냉매의 압축작용을 수행하는 실린더장치는 실린더내를 왕복동하는 피스톤과, 이 피스톤을 수용하며 압축공간을 형성하는 실린더블럭을 가진다. 실린더블럭에는 실린더의 개구를 차단하는 실린더헤드가 결합되며, 실린더블럭과 실린더헤드사이에는 냉매의 흡입과 토출이 순차적으로 가능하도록 밸브장치가 개재되어 있다. 압축기는 주기적으로 냉매를 흡입하게 되므로 충분한 흡입량을 확보하기 위하여 흡입머플러를 구비하고 있다. 냉매의 흡입시에는 얇은 판상의 금속재질의 흡입밸브가 흡입공을 반복적으로 개폐함에 따라 타격소음이 발생하게되며, 이 소음을 감소시키기 위해서 흡입머플러는 그 내부에 소음감쇠구조를 형성하고 있다.Refrigerating apparatuses, such as a refrigerator, are provided with the compressor which compresses the gaseous-phase refrigerant from an evaporator, and makes it into a high pressure refrigerant gas, and discharges it. The cylinder device which performs the compression action of the refrigerant has a piston reciprocating in the cylinder, and a cylinder block for accommodating the piston and forming a compression space. The cylinder block is coupled to the cylinder block to block the opening of the cylinder, and a valve device is interposed between the cylinder block and the cylinder head to sequentially allow the suction and discharge of the refrigerant. Since the compressor periodically sucks the refrigerant, the compressor has a suction muffler to secure a sufficient suction amount. When the refrigerant is sucked in, a thin plate-shaped metal suction valve opens and closes the suction hole repeatedly, and blow noise is generated. In order to reduce the noise, the suction muffler has a noise damping structure therein.

도 3은 종래의 밀폐형 왕복동식 압축기용 흡입머플러의 단면도이다. 도시된 바와 같이, 흡입머플러는 압축될 기상매체의 수용공간을 형성하며 주공명실(65)를 이루고 있는 머플러본체(60)와 머플러본체(60)의 상단부에 기밀이 유지되도록 결합되는 상부커버(61)와 머플러본체(60)의 하부영역에 결합되며 냉매를 실린더장치에 전달하는 토출구를 형성하고 있는 베이스부재(63)를 가진다. 또한, 머플러본체(60)의 내부에는 베이스부재(63)의 상부커버(61)측 단부에 결합되는 관상의 배플(67)이 결합되어 있다. 주공명실(65)과 배플(67)사이에는 부공명실(66)을 형성하는 격벽이 마련되어 있다. 머플러본체(60)의 일측에는 냉매가 유입될 수 있도록 흡입구(62)가 형성되어 있으며, 이 흡입구(62)에는 흡입스프링(59)을 매개하여 흡입관(58)이 결합되어 있다.3 is a cross-sectional view of a conventional suction muffler for hermetic reciprocating compressor. As shown, the suction muffler forms a receiving space of the gaseous medium to be compressed and the upper cover 61 coupled to maintain the airtight portion at the upper end of the muffler main body 60 and the muffler main body 60 forming the main resonance chamber 65. ) And a base member 63 coupled to the lower region of the muffler main body 60 and forming a discharge port for transferring the refrigerant to the cylinder device. In addition, a tubular baffle 67 coupled to the inner end of the upper cover 61 side of the base member 63 is coupled to the muffler body 60. Between the main resonance chamber 65 and the baffle 67, the partition which forms the sub resonance chamber 66 is provided. A suction port 62 is formed at one side of the muffler main body 60 to allow a refrigerant to flow therein, and the suction pipe 62 is coupled to the suction port 62 via a suction spring 59.

한편, 흡입관(58)으로부터 유입된 냉매는 머플러본체(60)와 상부커버(61)에 의해 형성된 수용공간에 수용되고, 관상의 배플(67)을 지나 베이스부재(63)에 형성된 토출구를 따라 실린더헤드(69)에 마련된 흡입공(70)으로 전달되어 진다. 흡입공(70)에 전달된 냉매는 압축기의 구동모터의 고속회전에 따라 실린더내로 흡입된다. 이때, 금속재질의 얇은 판상으로 형성된 흡입밸브플레이트는 반복적인 타격음을 발출하게 되고, 이 타격음은 냉매의 흡입경로를 역행하여 흡입머플러(51)내로 전파된다. 머플러본체(60)의 내부로 전달된 타격음은 배플(67)의 주변영역에서 저주파대역의 음파가 공명을 일으켜 감쇠된다.On the other hand, the refrigerant introduced from the suction pipe 58 is accommodated in the receiving space formed by the muffler main body 60 and the upper cover 61, and passes through the tubular baffle 67 to the cylinder along the discharge port formed in the base member 63 It is delivered to the suction hole 70 provided in the head (69). The refrigerant delivered to the suction hole 70 is sucked into the cylinder according to the high speed rotation of the drive motor of the compressor. At this time, the suction valve plate formed of a thin metal plate emits a repeated blow sound, which blows back into the suction path of the refrigerant and propagates into the suction muffler 51. The blow sound transmitted to the interior of the muffler body 60 is attenuated by the sound waves in the low frequency band in the peripheral region of the baffle 67.

그런데, 종래의 밀폐형 왕복동식 압축기용 흡입머플러에서는, 실린더로부터의 소음이 그 내부에서 충분히 감쇠되지 못하고, 흡입관을 통하여 압축기내부 및 외부로 배출된다는 문제점이 있다.By the way, in the conventional hermetic suction reciprocating compressor suction muffler, the noise from the cylinder is not sufficiently attenuated therein, and there is a problem that it is discharged into and out of the compressor through the suction pipe.

따라서, 본 발명의 목적은, 흡입관을 통해 외부로 전달되는 소음을 최소화할 수 있도록 하는 밀폐형 왕복동식 압축기용 흡입머플러를 제공하는 것이다.Accordingly, an object of the present invention is to provide a suction reciprocating suction muffler for minimizing the noise transmitted to the outside through the suction pipe.

이하에서는 첨부된 도면을 참조하여 본 발명에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

도 1은 본 발명에 따른 흡입머플러가 장착된 밀폐형 왕복동식 압축기의 단면도로서, 실린더헤드측에서 본 단면도이다. 도시된 바와 같이, 압축기의 외부케이싱(1)내에는 압축기본체(3)가 수용되어 있다. 압축기본체(3)는 하부 영역에 냉매압축용 실린더장치가 마련되어 있고, 실린더장치의 전면에는 실린더헤드(19)가 결합되어 있다. 이 실린더헤드(19)에는 냉매를 공급할 수 있도록 상부에 흡입머플러(7)가 결합되어 있다. 또한, 흡입머플러(7)는 압축기 외부로부터 냉매가 공급될 수 있도록 흡입관(8)에 흡입스프링(9)을 매개로 결합되어 있다.1 is a cross-sectional view of a hermetic reciprocating compressor equipped with a suction muffler according to the present invention, seen from the cylinder head side. As shown, the compressor body 3 is housed in the outer casing 1 of the compressor. The compressor main body 3 has a cylinder device for refrigerant compression in a lower region, and a cylinder head 19 is coupled to the front surface of the cylinder device. The cylinder head 19 has a suction muffler 7 coupled to the upper portion to supply a refrigerant. In addition, the suction muffler (7) is coupled to the suction pipe (8) via the suction spring (9) so that the refrigerant can be supplied from the outside of the compressor.

도 2는 본 발명에 따른 흡입머플러의 단면도이다. 본 발명에 따른 밀폐형 왕복동식 압축기용 흡입머플러는, 도 3에 도시된 종래의 흡입머플러와 마찬가지로, 압축될 냉매의 수용공간을 형성하며 주공명실(15)을 형성하는 머플러본체(10)와, 머플러본체(10)에 결합되는 상부커버(11)와, 머플러본체(10)의 하부영역에 결합되며 냉매의 토출구를 형성하고 있는 베이스부재(13)를 가진다. 머플러본체(10)의 일측에는 냉매가 유입될 수 있도록 흡입구(12)가 형성되어 있으며, 이 흡입구(12)에는 흡입스프링(9)을 매개하여 흡입관(8)이 결합되어 있다. 또한, 머플러본체(10)의 내부에는 베이스부재(13)의 상부커버(11)측 단부에 결합되는 관상의 배플(17)이 결합되어 있다. 배플(17)은 머플러본체(10)의 내부공간을 구획하여 유로를 형성하는 한편, 외측으로 연장된 플랜지부와 상부커버(11)측으로 연장된 리브부를 가진다. 배플(17)의 플랜지부는 주공명실(15)과 배플(17)사이에 마련된 격벽과 함께 부공명실(16)을 형성하고 있다. 관상의 냉매토출구를 형성하고있는 베이스부재(13)는 실린더장치에 압축될 냉매를 공급하도록 실린더헤드(19)에 마련된 그루브에 결합되어 있다.2 is a cross-sectional view of the suction muffler according to the present invention. The suction muffler for the hermetic reciprocating compressor according to the present invention, like the conventional suction muffler shown in FIG. 3, includes a muffler main body 10 forming a receiving space for the refrigerant to be compressed and forming a main resonance chamber 15, and a muffler. An upper cover 11 coupled to the main body 10 and a base member 13 coupled to the lower region of the muffler main body 10 and forming a discharge port of the refrigerant. On one side of the muffler main body 10, a suction port 12 is formed to allow the refrigerant to flow therein, and the suction pipe 8 is coupled to the suction port 12 via the suction spring 9. In addition, a tubular baffle 17 coupled to the inner end of the upper cover 11 side of the base member 13 is coupled to the muffler body 10. The baffle 17 partitions the inner space of the muffler body 10 to form a flow path, and has a flange portion extending outwardly and a rib portion extending toward the upper cover 11 side. The flange part of the baffle 17 forms the sub resonance chamber 16 with the partition provided between the main resonance chamber 15 and the baffle 17. The base member 13 forming the tubular refrigerant discharge port is coupled to a groove provided in the cylinder head 19 to supply the refrigerant to be compressed to the cylinder device.

머플러본체(10)의 일측에는 형성된 관상의 흡입구(12)가 형성되어 있어, 실린더헤드(19)로부터 전달되는 진동의 흡수가 용이하도록 흡입스프링(9)이 결합되어 있다. 흡입스프링(9)은 원통형상으로 코일이 밀착되게 형성되어 있어 냉매가스의 누설이 방지되도록 되어 있다. 이 흡입구(12)에 인접한 배플(17)의 상부연부와 이에 대향하는 상부커버(11)의 내측표면에는 하부소음감쇠리브(21b)와 상부소음감쇠리브(21a)가 각각 형성되어 있다. 이 소음감쇠리브(21b, 21a)들은 얇은 판상부재로 형성되어 흡입구(12)에 근접할수록 유동단면적이 좁아 지도록 서로 대향하여 배치되어 있다.One side of the muffler main body 10 is formed with a tubular suction port 12 is formed, the suction spring 9 is coupled to facilitate the absorption of the vibration transmitted from the cylinder head (19). The suction spring 9 is formed in a cylindrical shape so that the coil is in close contact with each other to prevent leakage of the refrigerant gas. Lower noise attenuation ribs 21b and upper noise attenuation ribs 21a are respectively formed on the upper edge of the baffle 17 adjacent to the suction port 12 and on the inner surface of the upper cover 11 opposite thereto. These noise damping ribs 21b and 21a are formed of a thin plate-like member and are disposed to face each other so that the flow cross-sectional area becomes narrower as the inlet 12 is closer.

한편, 이러한 구성에 의하여 냉매는 압축기외부로부터 흡입관(8)을 통하여 압축기내로 유입되고, 흡입스프링(9) 및 소음감쇠리브(21a, 21b)를 거쳐 배플(17) 과 주공명실(15)로 향하게 된다. 배플(17)을 지난 냉매는 베이스부재(13)에 형성된 토출구를 따라 실린더헤드(19)의 냉매흡입공(20)을 통하여 실린더(미도시)내부로 유입된다. 한편, 고속으로 회전하는 구동모터의 회전에 따라 흡입밸브는 개폐를 반복하고, 이에 따라 발생되는 연속타격소음은 냉매가 흡입되는 경로와는 반대 경로를 거쳐 흡입관(8)을 통해 외부로 배출되게 된다.On the other hand, by this configuration, the refrigerant flows into the compressor from the outside of the compressor through the suction pipe 8, and passes through the suction spring 9 and the noise damping ribs 21a and 21b to the baffle 17 and the main resonance chamber 15. do. The refrigerant passing through the baffle 17 is introduced into the cylinder (not shown) through the refrigerant suction hole 20 of the cylinder head 19 along the discharge hole formed in the base member 13. On the other hand, the suction valve is opened and closed repeatedly as the drive motor rotates at a high speed, and the continuous blow noise generated by this is discharged to the outside through the suction pipe 8 through a path opposite to the path through which the refrigerant is sucked. .

그런데, 소음을 일으키는 진동의 일부는 베이스부재(13)를 지나 배플(17)의 주위에 형성되어 있는 부공명실(16)에 투과파를 발생시키면서 음파에너지가 감쇠된다. 또한, 일부는 배플(17)을 지나 주공명실(15)로 전달되어 가스상태의 냉매분자를 직접진동시키고, 이에 따라, 음파에너지가 소실되어 소음이 감쇠된다. 한편, 주공명실(15)과 부공명실(16)에서 일부 음파에너지를 소실한 소음은 흡입구(12)측을 향하여 유동단면적이 좁아지도록 형성된 소음감쇠리브(21a, 21b)를 통과하게 된다. 이때, 소음은 소음감쇠리브(21a, 21b)에 부딪치면서 내향하는 반사파를 발생시키고, 소음감쇠리브(21a, 21b)를 진동시키면서 음파에너지의 일부가 소실되게 된다. 그리고, 다시 좁은 곳에서 넓은 곳으로 팽창되면서 회절하여 다시 일부의 음파에너지를 소실하게 된다. 이와 같이, 머플러본체(10)의 내부에 한 쌍의 소음감쇠리브(21a, 21b)를 마련하여 부공명실(16)과 주공명실(15)에 의해 감쇠되지 못한 소음을 소음감쇠리브(21a, 21b)를 통하여 감쇠시킴으로써, 소음감쇠효과를 중대시킬 수 있다.By the way, a part of the vibration which causes noise attenuates sound wave energy while generating a transmission wave to the sub resonance chamber 16 formed around the baffle 17 through the base member 13. In addition, a part of the gas is transferred to the main resonance chamber 15 through the baffle 17 to directly oscillate the refrigerant molecules in a gaseous state. On the other hand, the noise that has lost some sound wave energy in the main resonance chamber 15 and the secondary resonance chamber 16 passes through the noise attenuation ribs 21a and 21b formed to narrow the flow cross-section toward the suction port 12 side. At this time, the noise hits the attenuation ribs 21a and 21b to generate an inward reflection wave, and part of the sound wave energy is lost while vibrating the attenuation ribs 21a and 21b. Then, it expands again from a narrow place to a wide place and diffracts it again to lose some sound wave energy. In this way, a pair of noise damping ribs 21a and 21b are provided in the muffler main body 10 to prevent noise that is not attenuated by the sub resonance chamber 16 and the main resonance chamber 15 by the noise damping ribs 21a and 21b. By damping through), the noise damping effect can be significant.

전술 및 실시예에서는, 흡입구의 인접영역에 판상의 한 쌍의 소음감쇠리브를 대향하도록 형성하여 설명하고 있지만, 형상이나 개수는 필요에 따라 달리 구성할 수 있다.In the above description and the embodiment, a pair of plate-shaped noise attenuation ribs are formed in the adjacent area of the suction port so as to face each other, but the shape and number can be configured differently as necessary.

상술한 바와 같이, 본 발명에 따르면, 흡입관을 통해 외부로 전달되는 소음을 최소화할 수 있도록 하는 밀폐형 왕복동식 압축기용 흡입머플러가 제공된다.As described above, according to the present invention, there is provided a suction muffler for hermetic reciprocating compressor that can minimize the noise transmitted to the outside through the suction pipe.
