Description
본 발명은 밀폐형 회전식 압축기의 토출소음저감장치에 관한 것으로, 특히 압축기의 운전시 발생되는 토출 맥동음을 실린더의 단면에 소체적의 공명기를 형성하여 저감하도록 한 것을 특징으로 하는 밀폐형 회전식 압축기의 토출소음저감장치에 관한 것이다.The present invention relates to a discharge noise reduction device for a hermetic rotary compressor, and in particular, to discharge discharge pulsation generated during operation of the compressor by reducing a small volume resonator on the cross section of the cylinder to reduce the discharge noise of the hermetic rotary compressor. It relates to an abatement device.
일반적인 밀폐형 회전식 압축기는 도 1 및 도 2에 도시한 바와 같이 실린더(10)와, 회전축에 연결되어 상기 실린더(10)내를 회전하며 냉매를 압축하는 롤러(15)와, 상기 실린더(10)내에 설치되며 롤러(15)와 접동하므로 실린더(10)내를 고압실과 저압실로 구분하는 베인(도면에 도시되지 않음)과, 상기 베인이 직선왕복운동 하도록 실린더(10)의 일측에 형성한 베인슬롯(14)과, 상기 베인에 의해 나누어진 실린더(10)의 고압실 일측에 형성하여 압축된 냉매를 실린더밖으로 토출하는 토출포트(11)와, 상기 실린더(10)의 상면에 체결되는 상부베어링(20)과, 상기 상부베어링(20)에 형성하여 상기 토출포트(11)와 연통되는 냉매토출통로(21)와, 상기 토출포트(11)일측에 형성한 냉매도입로(12)와, 그 냉매도입로(12)의 단부에 형성한 공명소(13)를 포함하여 구성된다.1 and 2, a general hermetic rotary compressor includes a cylinder 10, a roller 15 connected to a rotating shaft to rotate inside the cylinder 10 and compressing a refrigerant, and the cylinder 10. Since the vane (not shown) divides the inside of the cylinder 10 into a high pressure chamber and a low pressure chamber because it is slid with the roller 15, and a vane slot formed at one side of the cylinder 10 to linearly reciprocate the vane ( 14), a discharge port 11 formed at one side of the high pressure chamber of the cylinder 10 divided by the vanes to discharge the compressed refrigerant out of the cylinder, and an upper bearing 20 fastened to the upper surface of the cylinder 10. ), A refrigerant discharge passage 21 formed in the upper bearing 20 to communicate with the discharge port 11, a refrigerant introduction passage 12 formed at one side of the discharge port 11, and a refrigerant introduction thereof. It is comprised including the resonance point 13 formed in the edge part of the furnace 12.
이와 같이 구성된 밀폐형 회전식 압축기의 동작은 다음과 같다. 실린더(10)내의 롤러(15)에 의해 압축된 냉매는 실린더(10)의 고압실 일측의 토출포트(11)를 통해 실린더(10) 상부로 토출되고, 상기 토출되는 냉매의 일부는 토출포트(11) 일측의 냉매도입로(12)를 통해 공명소(13)로 들어가게 된다. 이러한 밀폐형 압축기의 실린더 또는 베어링 근방의 일정공간은 토출직전의 고압 가스의 완충역할을 할 뿐만 아니라 토출되는 냉매의 맥동소음을 저감하는 기능을 하게 되며, 상기 일정공간인 공명소(13)에 유입된 냉매는 공명소(13)를 거쳐 다시 냉매토출통로(21)를 통해 실린더 밖으로 토출된다.The operation of the hermetic rotary compressor configured as described above is as follows. The refrigerant compressed by the roller 15 in the cylinder 10 is discharged to the upper portion of the cylinder 10 through the discharge port 11 on one side of the high pressure chamber of the cylinder 10, and a part of the discharged refrigerant is discharge port ( 11) through the refrigerant introduction path 12 of one side is to enter the resonance (13). A certain space near the cylinder or bearing of the hermetic compressor not only serves as a buffer for the high pressure gas immediately before the discharge, but also serves to reduce the pulsation noise of the discharged refrigerant, and flows into the resonance space 13 as the constant space. The refrigerant is discharged out of the cylinder through the refrigerant discharge passage 21 through the resonance point 13 again.
그러나, 상기 공명소(13)가 고압가스의 토출직전 완충역할을 충분히 하기 위해서는 공명소(13)의 체적이 클수록 유리한 구조가 되나, 토출시 미처 토출되지 못하고 남아있는 냉매가스는 실린더(10) 내부로 다시 회수되어 손실로써 작용하게 되는 문제점이 있다.However, in order for the resonator 13 to sufficiently buffer the discharge of the high pressure gas, the larger the volume of the resonator 13 becomes, the more advantageous the structure becomes. However, the refrigerant gas remaining undischarged at the time of discharge remains in the cylinder 10. There is a problem in that it is recovered again to act as a loss.
따라서, 본 발명의 목적은 상기와 같은 문제점을 고려하여 안출한 것으로, 공명소의 체적을 줄이면서도 토출되는 냉매의 소음저감성능을 높일 수 있도록 한 밀폐형 회전식 압축기의 토출소음저감장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a discharge noise reduction device for a hermetic rotary compressor to increase the noise reduction performance of the refrigerant discharged while reducing the volume of the resonance.
