Field of the Invention The present invention relates to a hermetic compressor for a refrigeration cycle of a refrigerator. In particular, a reciprocating compressor employs a side branch resonator to reduce the noise of a compressor, particularly a specific frequency band. It relates to a noise reduction device of the hermetic reciprocating compressor used.
압축기는 일반적으로 증발이 쉽게 이루어지도록 증발된 저온, 저압의 냉매증기를 흡입하는 펌프의 역할, 흡수된 증기를 쉽게 응축될 수 있도록 고온, 고압의 증기로 압축하는 역할 및 압축의 힘으로 냉매를 냉동기 내에 순환시키는 역할을 연속적으로 행하는 냉장고 부품이다. 그러므로 압축기는 증발압력, 응축압력등과 같은 압력과, 압축비, 피스턴 배출량, 냉매의 종류, 고온 고압으로 압축된 냉매증기를 응축시키기 위하여 공급하는 공기나 물(응축재)의 온도와 유동상태에 따라 그 구조 및 형태, 작동방법에 많은 차이가 있다.The compressor generally serves as a pump for sucking low-temperature and low-pressure refrigerant vapor evaporated to facilitate evaporation, compressing the absorbed vapor into high-temperature and high-pressure steam for easy condensation, and compressing the refrigerant with a compression force. It is a refrigerator component which performs the role which circulates continuously inside. Therefore, the compressor is used according to the pressure such as evaporation pressure and condensation pressure, and the compression ratio, piston output, type of refrigerant, temperature and flow state of air or water (condensing material) supplied to condense the refrigerant vapor compressed to high temperature and high pressure. There are many differences in the structure, form and method of operation.
이러한 압축기의 종류에는 피스톤의 왕복운동을 통해서 냉매가스를 압축하는 왕복동식 압축기와, 실린더 내의 회전자를 회전시켜 냉매가스를 압축하는 회전식 압축기 및 임펠러의 원심력을 이용하여 속도에너지를 압력에너지로 변환시켜 냉매가스를 압축하는 터보 압축기등이 있다.This type of compressor includes a reciprocating compressor that compresses refrigerant gas through a reciprocating motion of a piston, a rotary compressor that rotates a rotor in a cylinder, and converts velocity energy into pressure energy using centrifugal force of an impeller. And a turbo compressor for compressing refrigerant gas.
도 1a는 종래기술에 따른 밀폐형 왕복동식 압축기의 평단면도이고, 도 1b는 그 정단면도이다.FIG. 1A is a plan sectional view of a hermetic reciprocating compressor according to the prior art, and FIG. 1B is a front sectional view thereof.
도시된 압축기에는 용접에 의해 밀폐된 상하부 케이스(10,20)에 압축기 본체가 내장되어 있다. 압축기 본체는 크게 프레임(30)과, 프레임의 하부에 설치되어 전동매체인 샤프트(60)를 회전시키는 모터부(40)와, 샤프트(60)의 회전운동을 직선운동으로 변환하여 흡입된 냉매가스를 압축 및 토출시키는 기계부(50)로 구성되어있다.In the illustrated compressor, a compressor body is built in upper and lower cases 10 and 20 sealed by welding. The compressor main body is largely provided with a frame 30, a motor unit 40 installed at a lower portion of the frame to rotate the shaft 60, which is a transmission medium, and a refrigerant gas sucked by converting the rotational movement of the shaft 60 into a linear movement. It consists of a mechanical part 50 for compressing and discharging.
프레임(30)은 모터부(40)와 기계부(50) 전체를 지지하며, 상하부 케이스(10,20)에 각각 완충 및 소음방지 수단인 사이드 스토퍼(70)와 코일 스프링(80)을 통하여 지지된다.The frame 30 supports the entire motor portion 40 and the mechanical portion 50, and is supported by the upper and lower cases 10 and 20 through side stoppers 70 and coil springs 80, which are cushioning and noise preventing means, respectively. do.
기계부(50)는 프레임 상단에 고정되는 실린더(110)와, 실린더(110)에 삽입되어 직선 왕복운동을 하는 피스톤(120) 및 상기 피스톤(120)과 샤프트(60)의 크랭크부(61) 사이에 연결되어 샤프트(60)의 회전운동을 직선운동으로 변환시켜 주는 피스톤 로드(130)로 구성되어 있다. 따라서, 모터부(40)에 의해 회전하는 샤프트(60)가 크랭크부(61)를 통하여 기계부(50)의 피스톤 로드(130)를 왕복운동시킴으로써 피스톤(120)이 실린더(110) 내에서 직선 왕복운동을 하여 실린더(110) 내로 흡입된 냉매가스를 압축 및 토출시켜 주고, 냉매가스는 냉동장치를 순환하면서 피냉각물체로부터 열을 빼앗아 소정의 냉동목적을 달성하게 된다.The mechanical part 50 includes a cylinder 110 fixed to the upper end of the frame, a piston 120 inserted into the cylinder 110 to linearly reciprocate, and a crank part 61 of the piston 120 and the shaft 60. Is connected to the piston rod 130 is configured to convert the rotational movement of the shaft 60 to a linear movement. Thus, the shaft 120 rotated by the motor portion 40 reciprocates the piston rod 130 of the mechanical portion 50 through the crank portion 61 so that the piston 120 is linear in the cylinder 110. The reciprocating motion compresses and discharges the refrigerant gas sucked into the cylinder 110, and the refrigerant gas takes heat from the object to be cooled while circulating the refrigeration apparatus to achieve a predetermined refrigeration purpose.
또한, 실린더(110)의 일측에는 흡입 및 토출밸브를 구비하는 밸브 플레이트(140)가 설치되어 있고, 밸브 플레이트의 외측에는 냉매가스의 흡입 및 토출을 안내하는 흡입 및 토출 머플러(150,160)가 설치되어 있으며, 흡입 및 토출 머플러에는 각각 흡입 및 토출 파이프(170,180)가 연결된다. 토출 머플러(160)는 실린더(110)에서 압축된 고온·고압의 냉매가스가 토출되는 토출측에 설치되어 냉매가스의 토출시 압력의 맥동에 의한 소음발생을 감소시키게 된다.In addition, a valve plate 140 having suction and discharge valves is installed at one side of the cylinder 110, and suction and discharge mufflers 150 and 160 which guide suction and discharge of refrigerant gas are installed outside the valve plate. The suction and discharge mufflers are connected to suction and discharge pipes 170 and 180, respectively. The discharge muffler 160 is installed on the discharge side through which the high-temperature / high-pressure refrigerant gas compressed from the cylinder 110 is discharged to reduce noise generated by the pulsation of the pressure during the discharge of the refrigerant gas.
도 2는 종래 토출 머플러의 구조를 나타낸 개략적인 조립 평면도로서, 토출 머플러(260)는 밸브 플레이트(140)와 함께 실린더(110)의 토출 측에 체결되며 냉매가스의 흡입을 위한 흡입구와 토출구 및 배출구를 구비하는 머플러 플레이트(270)와, 토출 및 배출구와 연통되는 1차방을 구비하며 내판과 외판으로 구성되는 밸브커버(280)와, 머플러 플레이트(270)의 배출구 측에 접합되며 배출구와 연통되는 2차방을 구비하는 머플러컵(290)과, 머플러컵(290)에 접합되는 토출파이프(180)와, 머플러컵(290)의 측면부에 연결 파이프(310)를 통하여 연결되는 별도의 공명형 소음기(300)로 구성되어 있다.Figure 2 is a schematic assembly plan view showing the structure of a conventional discharge muffler, the discharge muffler 260 is fastened to the discharge side of the cylinder 110 together with the valve plate 140, the inlet and outlet and discharge port for the suction of the refrigerant gas 2 is provided with a muffler plate 270 having a primary chamber communicating with discharge and discharge ports and having a valve cover 280 composed of an inner plate and an outer plate and being connected to the discharge port side of the muffler plate 270 and communicating with the discharge port. Muffler cup 290 having a differential, a discharge pipe 180 bonded to the muffler cup 290, and a separate resonance type silencer 300 connected to the side portion of the muffler cup 290 through a connecting pipe 310 It consists of).
이와 같은 토출 머플러(260)는 기계부(50)의 피스톤(120)이 샤프트(60)에 의해 왕복운동을 하면서 실린더(110) 내의 냉매가스를 압축하면, 이 냉매가스가 머플러 플레이트(270)의 토출구를 통하여 밸브커버(280)의 1차방으로 토출된 다음, 다시 배출구와 머플러컵(290) 및 토출 파이프(180)를 통하여 토출되도록 되어있다. 이 때, 토출시 발생하였던 냉매가스의 맥동음 및 밸브의 타격음은 머플러컵(290)과 연결 파이프(310)로 연결된 공명형 소음기(300)를 통과하면서 투과손실에 의해 감쇠되어진다.The discharge muffler 260 compresses the refrigerant gas in the cylinder 110 while the piston 120 of the mechanical part 50 reciprocates by the shaft 60. After the discharge port is discharged to the first direction of the valve cover 280, it is discharged again through the discharge port, the muffler cup 290 and the discharge pipe 180. At this time, the pulsation sound of the refrigerant gas and the blow sound of the valve generated during the discharge are attenuated by the transmission loss while passing through the resonance silencer 300 connected to the muffler cup 290 and the connection pipe 310.
그러나, 상술한 바와 같은 밀폐형 왕복동식 압축기의 소음 저감구조는, 머플러컵(290)에 단순히 그와 동일한 형태의 공명형 소음기(300)를 부착한 것에 불과하므로 공명에 의한 투과손실량이 적어 토출 밸브의 타격음이나 냉매 압축으로 인해 발생하는 소음을 감쇠시키기에는 미약한 단점이 있다. 즉, 토출시 발생하였던 냉매가스의 밸브의 타격음이나 맥동음이 머플러컵과 공명형 소음기에 의해서 전량 감쇠되지 못할 뿐만 아니라, 큰 설치공간을 필요로한다는 문제점이 있었다.However, the noise reduction structure of the hermetic reciprocating compressor as described above is simply attached to the muffler cup 290 with a resonance type silencer 300 of the same type. There is a weak point to attenuate the noise caused by the blow sound or refrigerant compression. That is, the blow and pulsation noises of the valve of the refrigerant gas generated at the time of discharging are not all attenuated by the muffler cup and the resonance silencer, but also require a large installation space.
본 발명은 상술한 바와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로, 압축기 작동시 토출밸브의 타격음이나 냉매 압축으로 인해 발생하는 소음 중에서 특정 주파수대의 소음을 감쇠시킬 수 있으면서, 설치공간을 거의 차지하지 않는 밀폐형 왕복동식 압축기의 소음 저감장치를 제공하는 것이다.The present invention has been made to solve the conventional problems as described above, while being able to attenuate the noise of a specific frequency band from the noise generated by the blow sound of the discharge valve or the refrigerant compression during operation of the compressor, while occupying almost no space for installation It is to provide a noise reduction device of the hermetic reciprocating compressor.
이와 같은 목적을 달성하기 위하여 본 발명은, 실린더 블록에 순차적으로 조립되는 밸브 플레이트와, 토출밸브와, 개스킷 및 토출 머플러를 구비하는 밀폐형 왕복동식 압축기에 있어서, 상기 개스킷의 토출유로 일측에, 압축기의 발생 소음 중 소정의 주파수를 감쇠시킬 수 있는 크기를 가지며 그 상방과 하방이 상기 토출머플러와 토출밸브에 의해 폐쇄되는 측지 공명기가 마련된 것을 특징으로 하는 밀폐형 왕복동식 압축기의 소음 저감장치를 제공한다.In order to achieve the above object, the present invention provides a closed-type reciprocating compressor including a valve plate sequentially assembled to a cylinder block, a discharge valve, a gasket and a discharge muffler, wherein the discharge flow path of the gasket is provided on one side of the compressor. It provides a noise reduction device of a closed-type reciprocating compressor having a size that can attenuate a predetermined frequency of the noise generated, and a geodetic resonator is closed up and down by the discharge muffler and the discharge valve.
