본 발명은 왕복동식 압축기의 흡입머플러에 관한 것으로 특히 압축기의 맥동에 의한 소음을 저감시킬 수 있도록 한 것이다.The present invention relates to a suction muffler of a reciprocating compressor, in particular to reduce the noise caused by the pulsation of the compressor.
종래 왕복동식 압축기는 제1도에 도시된 바와 같이 고정자 및 회전자로 이루어지는 전동기구부(1)와 상기 전동기구부에서 전달된 회전운동을 왕복직선운동으로 바꾸어 냉매를 압축하고 피스톤 등으로 형성되는 압축기구부(2)와 상기 압축기구부에서 압축되는 냉매의 흡, 토출기구부(3)와 상기 구성원들을 모두 포함하는 밀폐용기(4)로 구성되었다.In the conventional reciprocating compressor, as shown in FIG. 1, the compressor mechanism 1 is formed of a piston and the like by compressing a refrigerant by changing the rotational motion transmitted from the electric mechanism part 1 consisting of a stator and a rotor into a reciprocating linear motion. (2) and an airtight container (4) including both the suction and discharge mechanism (3) of the refrigerant compressed by the compression mechanism unit and the members.
그리고, 상기 흡, 토출기구부는 흡입구(5)로 유입된 냉매가스가 압축기구부로 흡입될 때 냉매가스의 소음 및 고온상승을 방지하는 흡입머플러(6)와 상기 흡입머플러를 나와 흡입실(7), 압축실, 토출실(8)을 지나 냉매가스가 토출되는 토출머플러(9)로 구성된다.In addition, the suction and discharge mechanisms include a suction muffler 6 and a suction chamber 7 which prevent the noise and high temperature rise of the refrigerant gas when the refrigerant gas introduced into the suction port 5 is sucked into the compressor mechanism. And a discharge muffler 9 through which the refrigerant gas is discharged through the compression chamber and the discharge chamber 8.
이상고 같은 구성을 가지는 종래 것의 부가적인 설명과 이에 따르는 문제점을 이하에서 기술한다.Additional explanations of the conventional one having the same configuration as above and the problems thereof will be described below.
왕복동식 압축기는 연속적은 압축이 이뤄지는 터보형 압축기와는 달리 압축을 단속적으로 실시한다.Reciprocating compressors perform compression intermittently, unlike turbo compressors where continuous compression is achieved.
따라서 압축장치내의 작동유체는 일정한 시간을 주기로 소음을 동반한 맥동현상을 일으킨다.Therefore, the working fluid in the compression device causes pulsation with noise at regular intervals.
따라서, 작동유체로 냉매가스를 사용하는 경우에는 흡입실(7)에서 맥동이 두드러지게 나타나지만 공동형의 종래 흡입머플러 구조는 맥동에 의한 소음을 막기에는 역부족이다.Therefore, in the case of using the refrigerant gas as the working fluid, the pulsation is prominent in the suction chamber 7, but the cavity type conventional suction muffler structure is insufficient to prevent the noise caused by the pulsation.
본 발명은 종래의 이러한 문제점을 해결하기 위한 것으로 흡입머플러에 흡입실에서 발생하는 맥동소음을 저감시키는 맥동소음저감수단을 구비함으로써 압축기의 맥동에 의한 소음을 저감시키도록 하는데 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve such a problem in the related art, and has an object to reduce noise caused by pulsation of a compressor by providing a pulsation noise reducing means for reducing pulsation noise generated in a suction chamber in a suction muffler.
본 발명 왕복동식 압축기의 흡입머플러는 맥동소음저감수단을 구비한 것을 특징으로 한다.The suction muffler of the reciprocating compressor of the present invention is characterized by including pulsation noise reduction means.
그리고, 상기 맥동수음저감수단은 제3도에 도시된 바와 같이 피스톤의 왕복동으로 인하여 흡입실(107)에서 발생한 맥동소음을 저감토록 흡입머플러(200)에서 연장되어 흡입구쪽으로 일정각도 굽어지도록 형성한 흡입머플러 입구관(201)과, 상기 흡입머플러 입구관(201)내에 설치되어 위상상쇄효과로 소음을 저감하도록 흡입실(107)에서 연장된 내관(202)를 구비하였다.In addition, the pulsation sound absorbing means is formed in such a way that the pulsation noise generated in the suction chamber 107 due to the reciprocating motion of the piston extends from the suction muffler 200 so as to bend at a predetermined angle toward the suction port as shown in FIG. A muffler inlet tube 201 and an inner tube 202 installed in the suction muffler inlet tube 201 extend from the suction chamber 107 to reduce noise by phase canceling effect.
이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
냉매가스를 압축시키기 위하여 압축기의 전동기에 전원이 인가되면 회전자가 회전력을 발생시킨다.When power is applied to the motor of the compressor to compress the refrigerant gas, the rotor generates a rotational force.
상기 회전력은 슬라이더 및 슬라이더쉘에 의하여 피스톤의 직선왕복운동으로 변환된다.The rotational force is converted into a linear reciprocating motion of the piston by a slider and a slider shell.
상기 피스톤의 직선왕복운동은 등엔트로피과정으로 매분당 수천회 이루어져 흡입구(5)와, 흡입머플러(200), 흡입실(107)과, 흡입밸브를 통하여 유입된 냉매가스를 고온고압으로 압축하여 토출배브와, 토출실(8)과, 토출머플러(9)를 통하여 외부로 배출한다.The linear reciprocating motion of the piston is performed thousands of times per minute in an isotropic process, and the refrigerant gas introduced through the suction port 5, the suction muffler 200, the suction chamber 107, and the suction valve is discharged by high temperature and high pressure. It discharges to the exterior through the barb, the discharge chamber 8, and the discharge muffler 9.
한편, 본 발명 흡입머플러(200)로 유입되는 냉매가스는 흡입머플러 내관(202)을 지나게 된다.On the other hand, the refrigerant gas flowing into the suction muffler 200 of the present invention passes through the suction muffler inner tube (202).
상기 내관(202)은 흡입머플러의 출구(OUT)쪽에서 흡입머플러의 입구관(201)내까지 연장되고 다수개의 구멍(203)이 뚫려 있는 것으로서,The inner pipe 202 extends from the outlet (OUT) side of the suction muffler to the inlet pipe 201 of the suction muffler and a plurality of holes 203 are drilled,
여기서, 다수개 구멍(203)의 역활은 흡입실(107)에서 가스맥동에 의한 소음이 흡입머플러의 출구(OUT)를 거쳐 냉매유입방향의 역방향으로 전파되어 나올 때, 흡입머플러의 공동(VA)과 공명현상에 의해 맥동소음을 저감시키는 것이다.Here, the role of the plurality of holes 203 is the cavity VA of the suction muffler when the noise caused by the gas pulsation propagates out in the reverse direction of the refrigerant inflow direction through the outlet OUT of the suction muffler in the suction chamber 107. Pulsation noise is reduced by over resonance.
또한, 맥동소음은 흡입머플러 내관(202)이 흡입머플러 입구관(201)내에 일정 깊이만큼 연장되어 형성되어 있으므로 발생하는 위상상쇄효과(Phase cancellation effect)로 감쇄된다.In addition, the pulsation noise is attenuated by a phase cancellation effect that occurs because the suction muffler inner tube 202 extends by a predetermined depth in the suction muffler inlet tube 201.
이와 같이 본 발명은 기존의 흡입머플러 외형은 거의 유지한 채 내부에 구멍 뚫은 내관을 이중관 형식으로 설치함으로써 냉매가스의 맥동에 의한 소음을 크게 줄일 수 있도록 한 것이다.As described above, the present invention is to reduce the noise caused by the pulsation of the refrigerant gas by installing the inner tube bored inside the double tube type while maintaining the outer shape of the existing suction muffler.
