본 고안은 밀폐형 전동압축기의 흡입머플러 구조에 관한 것으로, 특히 흡입공명실 내부에 격막과 격막으로 분리된 미세 공명유로를 형성하여 흡입되는 냉매가스의 불연속적인 유동특성과 운전중의 진동특성을 감쇠하도록 한 밀폐형 전동압축기의 흡입머플러 구조에 관한 것이다.The present invention relates to a suction muffler structure of an enclosed electric compressor, and in particular, to form a micro resonance path separated into a diaphragm and a diaphragm inside the suction resonance chamber to attenuate the discontinuous flow characteristics of the refrigerant gas sucked and vibration characteristics during operation. A suction muffler structure of a hermetic electric compressor.
일반적인 밀폐형 전동 압축기는 제1도에 도시한바와 같이, 외부전원을 인가받아 전기적 에너지를 회전자(4)와 고정자(3)를 통해서 기계적 에너지로 변환시켜 크랭크 샤프트(5)의 회전력을 편심부와 피스톤(6)에 의해 왕복 압축운동으로 변환시키게 된다. 외부인가 전원에 의해 생성된 왕복운동 에너지는 제2도의 흡입머플러(11)를 통해 냉매가스를 흡입하고 압축실에서 냉매가스를 압축하여 루우프 파이프(9)를 통해 압축된 냉매가스를 내보내게 된다.As shown in FIG. 1, a general hermetic electric compressor receives external power and converts electrical energy into mechanical energy through the rotor 4 and the stator 3 to convert the rotational force of the crankshaft 5 into an eccentric portion. The piston 6 converts it into a reciprocating compression motion. The reciprocating kinetic energy generated by the externally applied power source sucks the refrigerant gas through the suction muffler 11 of FIG. 2 and compresses the refrigerant gas in the compression chamber to discharge the compressed refrigerant gas through the loop pipe 9.
그러나, 이러한 종래의 흡입머플러(11) 구조는 흡입머플러 내부공명소(12)가 단일체적요소를 갖고 있어, 외부 또는 내부로 부터의 진동 및 맥동음을 저감하는 효과가 미비한 구조로 구성되어 있다. 흡입되는 냉매가스와 압축일을 하는 동안 발생되는 진동 및 맥동음이 흡입머플러(11)를 통해서 전달되는 유체압력을 받아서 흡입머플러가 전체적으로 단일변동 특성을 지니게 되어 진동 및 맴동음의 산포가 심하게 발생되는 문제점이 있다.However, the structure of the conventional suction muffler 11 has a structure in which the suction muffler internal resonance element 12 has a single volume element, so that the effect of reducing vibration and pulsation noise from the outside or the inside is insufficient. The vibration and pulsation sound generated during the compression work with the refrigerant gas being sucked receives the fluid pressure transmitted through the suction muffler 11, and the suction muffler has a single fluctuation characteristic as a whole. There is a problem.
따라서, 본 고안의 목적은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 흡입공명실 내부에 격막과 격막으로 분리된 미세 공명유로를 형성하여 흡입되는 냉매가스의 불연속적인 유동특성과 운전중의 진동특성을 감쇠하도록 한 밀폐형 전동압축기의 흡입머플러 구조를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, to form a fine resonance flow path separated into the diaphragm and the diaphragm inside the suction resonance chamber, the discontinuous flow characteristics of the refrigerant gas is sucked and vibration during operation It is to provide a suction muffler structure of a hermetic electric compressor to attenuate characteristics.
상기한 목적을 달성하기 위해 본 고안은 냉매가스를 흡입하기 위한 유로가 형성되는 흡입 머플러에 있어서, 상기 흡입머플러의 유로의 압측과 연통되도록 형성되는 공명소와, 상기 공명소의 내부에 격막이 형성된 것을 특징으로 하는 밀폐형 전동압축기의 흡입머플러 구조가 제공되므로써 달성된다.In order to achieve the above object, the present invention provides a suction muffler, in which a flow path for sucking refrigerant gas is formed, a resonance element formed to communicate with the pressure side of the flow path of the suction muffler, and a diaphragm formed inside the resonance point. It is achieved by providing a suction muffler structure of a hermetically sealed electric compressor.
여기서, 상기 공명소 내부의 격막은 서로 엇갈리게 형성되어 상기 공명소가 미세한 유로로 형성되는 것을 그 특징으로 한다.Here, the diaphragm inside the resonator are alternately formed so that the resonator is formed in a fine flow path.
이하, 상기한 목적을 달성하기 위한 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object in detail as follows.
제4도는 본 고안에 의한 압축기의 흡입머플러의 내부구조를 나타내는 단면도를 보인 것으로, 이에 도시한 바와 같이, 본고안에 의한 밀폐형 전동압축기의 흡입머플러(21) 구조는 내부벽에 의해 유로(13) 및 공명소(12)를 형성한 밀폐형 전동압축기의 흡입머플러 구조에 있어서, 상기 흡입머플러의 내부에 유로의 일측과 연통되도록 공명소(21)가 형성되고, 상기 공명소(12)의 내부에 격막(22)을 다수개 형성하여 내부체적을 미세하게 분리하도록 한다.4 is a cross-sectional view showing the internal structure of the suction muffler of the compressor according to the present invention, as shown in the drawing, the structure of the suction muffler 21 of the hermetic electric compressor according to the present invention has a flow path 13 and an empty space by the inner wall. In the suction muffler structure of the hermetic electric compressor, in which the spot 12 is formed, a resonance point 21 is formed in the suction muffler so as to communicate with one side of the flow path, and the diaphragm 22 is formed inside the resonance point 12. ) To form a plurality of) to finely separate the internal volume.
상기 격막이 공명소(12) 내부에 서로 엇갈리게 형성되어, 흡입유체의 미세 공명유로(23)가 지그재그로 되어 길어지도록 형성된다.The diaphragm is alternately formed inside the resonance element 12, so that the fine resonance flow path 23 of the suction fluid is zigzag long.
이와 같이 구성된 본 고안에 의한 밀폐형 전동압축기의 흡입머플러 구조의 작용효과를 설명하면 다음과 같다.Referring to the effect of the suction muffler structure of the hermetic electric compressor according to the present invention configured as described above are as follows.
흡입되는 냉매가스가 흡입초기에 흡입머플러(21)의 흡입공명실내에 유입되어 유로(13)와 공명소(12)로 이루어진 흡입공명실을 가득 채우게 되는데 이때 밀폐형 전동압축기의 냉매흡입과정에서 생기는 불연속적인 유체유동과 압축기의 압축운전 과정에서 전파되는 진동특성을 감쇠하는 역할을 하게 되는데 종래의 던일체적으로 구성된 흡입공명소는 상호 감쇠하는 특성이 미비한데 반하여 본 고안이 흡입머플러 내부의 공명소(12)에 설치한 격막(22)은 단일체적요소를 미세하게 상호분리하여 미세공명 유로(23)를 형성하여 격막(22)으로 분리된 각각의 미세공명유로의 완충효과를 증대시킬 수 있게 된다. 유체압력의 맥동특성과 운전중의 진동특성이 흡입머플러에 영향을 미치게 될 때 격막(22)과 격막으로 분리된 미세 공명유로(23)가 상호작용하여 흡입머플러의 흡입공명실의 제기능을 높이는 역할을 하게 된다.The refrigerant gas to be sucked is introduced into the suction resonance chamber of the suction muffler 21 at the beginning of the suction to fill the suction resonance chamber composed of the flow path 13 and the resonance chamber 12. In this case, discontinuity generated during the refrigerant suction process of the hermetic electric compressor. In the conventional fluid flow and the compression operation of the compressor to act to attenuate the vibration characteristics propagation of the conventional dunilil suction respiratory features are inadequate mutual attenuation characteristics, while the present design is the resonant internals of the suction muffler ( The diaphragm 22 installed in 12 can finely separate single volume elements to form a micro resonance channel 23 to increase the buffering effect of each micro resonance channel separated by the diaphragm 22. When the pulsation characteristics of the fluid pressure and the vibration characteristics during operation affect the suction muffler, the diaphragm 22 and the micro resonance path 23 separated by the diaphragm interact to enhance the function of the suction resonance chamber of the suction muffler. It will play a role.
본 고안의 목적달성을 위해 내주구조의 단일체적 요소를 각각의 체적으로 상호분리하여 각각의 체적요소가 상호 완충작용하여 진동 및 맥동특성을 감쇠하도록 여러 형상으로 조정하여도 같은 효과를 얻을 수 있다.In order to achieve the object of the present invention, the same effect can be obtained even if the single volume elements of the inner circumferential structure are separated into each volume and each volume element is mutually buffered to reduce vibration and pulsation characteristics.
이상에서 설명한 바와같이, 본 고안에 의한 밀폐형 전동압축기의 흡입머플러 구조는 내부벽에 의해 유로 및 공명소를 형성한 밀폐형 전동압축기의 흡입머플러 구조에 있어서, 상기 공명소내부에 격막을 다수개 형성하여 내부체적을 미세하게 분리 하므로, 흡입공명실 내부에 격막과 격막으로 분리된 미세 공명유로로 흡입되는 냉매가스의 불연속적인 유동특성과 운전중의 진동특성을 감쇠하도록 한 효과가 있다.As described above, the suction muffler structure of the hermetic electric compressor according to the present invention has a suction muffler structure of the hermetic electric compressor in which a flow path and a resonance point are formed by an inner wall, and a plurality of diaphragms are formed inside the resonance chamber.
