본 고안은 공기조화기 등에 적용되는 대체로 용량이 큰 밀페형 전동압축기에 있어서, 냉매가스의 흡입시 발생되는 소음을 절감시키도록 한 밀폐형 전동 압축기의 소음 감소 장치에 관한 것이다.The present invention relates to a noise reduction device of a hermetic electric compressor, which is designed to reduce noise generated when suction of refrigerant gas in a large-capacity sealed electric compressor generally applied to an air conditioner.

일반적으로 밀폐형 전동압축기는 제 1 도에서와 같이 회전자(2)의 회전에 의해 이것과 일체화 되어 크랭크축(3)이 회전하게 되고, 크랭크축(3)은 편심부에 삽입되어 있는 피스톤(4)을 작동시켜 실린더(5)내의 냉매를 압축시키게 된다.In general, the hermetic electric compressor is integrated with this by the rotation of the rotor 2 as shown in FIG. 1 so that the crankshaft 3 rotates, and the crankshaft 3 is a piston 4 inserted into an eccentric part. ) To compress the refrigerant in the cylinder (5).

압축된 냉매가스는 밸브 플레아트(6)를 지나 토출관(7)을 경유하여 밀폐용기91) 상부의 토출연결관(8)을 거쳐서 도시되지 않은 냉동 싸이클로 송출되어 순환되어지며 저온저압으로 된 냉매가스는 다시 흡입연결과(9)을 통하여 밀폐용기(1)내로 흡입하게 된다.The compressed refrigerant gas passes through the valve plate 6 and is discharged to the refrigeration cycle (not shown) through the discharge connection pipe 8 above the sealed container 91 through the discharge pipe 7 and circulated to the low temperature and low pressure. The gas is sucked back into the sealed container 1 through the suction connection 9.

이 밀폐용기(1)내로 흡입된 냉매는 흡입통로(10)를 통하여 실린더헤드부(11)로 들어오게 되는 것이었다.The refrigerant sucked into the hermetic container 1 enters the cylinder head portion 11 through the suction passage 10.

이같은 밀폐형 전동 압축기에 있어서, 종래에는 제 2 도와 제 3 도에서와 같이 흡입통로(10)를 통하여 흡입되는 가스는 먼저 펴측양방에 설치된 흡입구(12)(12')를 거쳐 실린더해드(11)내의 흡입실(13)를 통과하여 실린더(5)내에 흡입되는 것이었다.In such a hermetic type electric compressor, conventionally, the gas sucked through the suction passage 10 as shown in FIG. 2 and FIG. 3 first passes through the suction ports 12 and 12 'provided on both sides of the cylinder head 11. It was sucked into the cylinder 5 through the suction chamber 13.

그러나. 이는 흡입통로(10)를 통하여 흡입되는 가스가 편측 양방에 설치된 양흡입구(12)(12')로 정확하게 흡입되지 않고, 양흡입구(12)(12')사이로도 떨어지기 때문에 이곳에서 소용돌기가 발생되고, 또한 공명(共鳴)으로 인해 냉매가스의 심한 흡입소음이 되는 결점이 있었다.But. This is because the gas sucked through the suction passage 10 is not accurately sucked into both suction inlets 12 and 12 'installed on both sides, and falls between the two suction inlets 12 and 12'. There was a drawback that was generated, and also due to resonance, severe suction noise of the refrigerant gas.

따라서 본 고안은 이와 같은 종래의 냉매 흡입구조에서 소음이 발생하던 문제점을 해소하고자 흡입통로 하부에 흡입 머플러 부재를 착설하여 흡입가스의 소용돌이와 공명음을 없애도록 한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, in order to solve the problem that noise occurs in the conventional refrigerant suction structure, the present invention installs the suction muffler member under the suction passage to remove the vortex and resonance sound of the suction gas. As follows.

밀폐형 전동 압축기내의 실린더헤드부(11)에 있어서, 중앙으로 유통공(140을 가진 타원형의 상부부재(15)와 이의 직하방이 양측방향으로 유통구멍(16)(16')을 가진 하부부재(17)를 일체로 형성한 흡입 머플러부재(18)를 실린더헤드(11)의 흡입통로(10) 하단에 설치하여서 흡입가스를 원활하게 유통시켜, 소음을 극소화 시킨 것이다.In the cylinder head portion 11 in a hermetic electric compressor, an elliptical upper member 15 having a distribution hole 140 in the center and a lower member 17 having distribution holes 16 and 16 'in both sides thereof in a lower side thereof. ), The suction muffler member 18 formed integrally is installed at the lower end of the suction passage 10 of the cylinder head 11 to smoothly distribute the suction gas and minimize noise.

이와 같은 본 고안은 종래와 같은 방법으로 압축기 내의 압축기 기구부에서 압축된 냉매가 토출연결과(8)을 거쳐서 냉동사이클로 송출되어 순환된 후 흡입연결관(9)를 통하여 밀폐용기(1)내로 흡입되게 되고, 이 흡입된 냉매는 흡입통로(10)를 통해 하단에 설치된 흡입머플러부재(18)를 거쳐 실린더 헤드부(11)로 흡입하게 되는데, 이때 흡입통로(10)를 통하는 냉매는 제 4 도와 같이 먼저 상부부재(15)의 중심부에 형성된 유통공(14)을 통과하게 되고, 이를 통과한 냉매는 직하방의 하부부재(17)의 양측으로 형성된 우통구명(16)(16')을 거치면서 실린더헤드(11)내의 흡입구(12)(12')로 흡입하게 흡입소음이 감소하게 되는 것이다.The present invention is designed such that the refrigerant compressed in the compressor mechanism in the compressor is discharged into the refrigeration cycle through the discharge connection section 8 and circulated through the suction connection pipe 9 in the same manner as the conventional method. The sucked refrigerant is sucked into the cylinder head portion 11 through the suction muffler member 18 installed at the bottom through the suction passage 10. At this time, the refrigerant passing through the suction passage 10 is the fourth degree. First, it passes through the distribution hole 14 formed in the center of the upper member 15, the refrigerant passing through the cylinder head while passing through the right life (16, 16 ') formed on both sides of the lower member 17 directly below Inhalation noise is reduced to be sucked into the suction ports 12 and 12 'in (11).

그리고, 흡입가스의 소용돌이와 공명소음을 감소하기 위하여 흡입 머플러부재(18)의 유통공(14)과 유통구멍(16)(16')의 크기를 소음의 주파수 특성 및 냉매의 유량에 상응하도록 조절하면 된다.Then, in order to reduce the vortex and resonance noise of the suction gas, the size of the distribution hole 14 and the distribution hole 16, 16 'of the suction muffler member 18 is adjusted to correspond to the frequency characteristics of the noise and the flow rate of the refrigerant. Just do it.

따라서 이와 같이 된 본 고안은 흡입통로(10)의 하단에 흡입머플러부재(18)를 착설하므로서 흡입되는 냉매가 유통공(14)과 유통구멍(16)(16')을 통해 원활하게 흡입되어 맥등에 의한 소용돌이 및 공명소음이 줄어드는 효과가 있는 유용한 고안인 것이다.Therefore, the present invention thus achieved, the refrigerant sucked by installing the suction muffler member 18 at the lower end of the suction passage 10 is smoothly sucked through the distribution hole 14 and the distribution hole 16, 16 ' It is a useful design with the effect of reducing the eddy and resonance noise by the back.
