본 고안은 밀폐형 압축기의 흡입장치에 관한 것으로서 특히 흡입측에서 발생되는 소음과 열접촉에 의한 냉매가스의 온도상승의 문제점을 해결할 수 있도록 한 것이다.The present invention relates to a suction device of a hermetic compressor, and in particular, to solve the problem of temperature rise of the refrigerant gas due to noise and heat contact generated on the suction side.

종래 압축기의 구성은 제1도 및 제2도에서와 같이 외곽케이스를 형성하는 쳄버(1)내부에는 프레임(4) 윗쪽에 장착된 압축부(17)와, 상기 프레임(4) 하부에 설치된 전동부(9)와, 상기 전동부(9) 중심에 삽입된 크랭크축(8)과, 상기 크랭크축(8)의 상부에 연결되어 실린더(6)내에서 왕복운동하는 피스톤(5)과, 상기 실린더(6)로 흡입파이프(3)를 통해 냉매가 흡입되는 흡입통로(10)와, 상기 실린더(6) 앞쪽 끝에 부착된 헤드커버부(7)에는 제1헤드커버(13)와 제2헤드커버(14)가 구성되었다.Conventional compressors have a compression unit 17 mounted above the frame 4 in the chamber 1 forming the outer case as shown in FIGS. A crankshaft 8 inserted into the eastern part 9, a center of the transmission part 9, a piston 5 connected to an upper portion of the crankshaft 8 and reciprocating in the cylinder 6, and The first head cover 13 and the second head are provided on the suction passage 10 through which the refrigerant is sucked into the cylinder 6 through the suction pipe 3, and the head cover portion 7 attached to the front end of the cylinder 6. The cover 14 was constructed.

도면중 미설명부호 11은 강판소음기이고 15는 로우터를 나타낸다.In the figure, reference numeral 11 denotes a steel sheet silencer and 15 denotes a rotor.

이와 같이 구성된 종래 밀폐형 압축기에 전원이 인가되면 먼저 전동부(9)의 로우터(15)가 회전하게 되므로 크랭크축(8)이 회전하게 되고 이에 의해 피스톤(5)이 실린더(6)내에서 왕복운동을 하게되며 이로인해 실린더(6)내에는 흡입력이 발생되어 냉매가 흡입파이프(1)를 통해 유입되고 유입된 냉매가 흡입통로(10)를 통해 실린더(6) 내부의 압축실로 들어가 실린더(6)내에서 고온고압으로 압축된후 토출소음기를 통해 쳄버(1) 외부로 토출되게 된다.When power is applied to the conventional hermetic compressor configured as described above, the rotor 15 of the electric drive unit 9 first rotates so that the crankshaft 8 rotates, thereby causing the piston 5 to reciprocate in the cylinder 6. Due to this, suction force is generated in the cylinder (6) so that the refrigerant is introduced through the suction pipe (1) and the introduced refrigerant enters the compression chamber inside the cylinder (6) through the suction passage (10). After being compressed to a high temperature and high pressure in the interior is discharged to the outside of the chamber (1) through the discharge silencer.

그러나 흡입측 소음저감장치는 공명부를 이루는 강판을 제작함에 있어서, 그 제조작업이 난해하고 상기 강판으로 완전 밀봉된 공명부를 형성하기에도 고도의 기술이 요구되며, 공명구멍이 흡입통로의 입구측에 근접형성되어 있기 때문에 소음감쇄 효과를 저하시키는 한편, 냉동유의 유입이 우려되는 문제점이 발생하였다.However, the suction side noise reduction device is difficult to manufacture the steel sheet forming the resonance portion, and even a high level of skill is required to form a resonance portion completely sealed with the steel sheet, and the resonance hole is close to the inlet side of the suction passage. Because it is formed, while reducing the noise damping effect, there is a problem that the inflow of refrigerated oil is concerned.

또한 헤드커버부(7)가 스틸(Steel)로 구성되어 있어 흡입되는 냉매가스의 온도를 상승시킴으로 압축기의 성능이 떨어지게 되는등의 문제점이 있었다.In addition, since the head cover portion 7 is made of steel, there is a problem such that the performance of the compressor is lowered by increasing the temperature of the refrigerant gas being sucked.

본 고안은 이러한 점을 감안하여 흡입소음기의 일측에는 상기 헤드커버와의 고정을 위한 돌기를 형성하고, 제1헤드커버의 상부에서 일측은 토출체적을 형성하고 타측은 상기 흡입소음기가 삽입되는 삽입홈을 형성하며, 상기 삽입홈의 일측에는 상기 흡입소음기의 돌기를 수용하는 수용부를 구비함으로서, 전동부로 부터의 열전달을 방지하여 열손실을 저감시키고 헤드커버와 플라스틱소음기의 소음투과를 방지하여 압축기의 성능을 향상시키도록 하는데 목적이 있다.The present invention has been made in view of this point, and a protrusion for fixing with the head cover is formed on one side of the suction silencer, one side of the first head cover is formed with a discharge volume and the other side is inserted groove into which the suction silencer is inserted And a receiving portion accommodating the protrusion of the suction silencer on one side of the insertion groove, to prevent heat transfer from the electric portion, to reduce heat loss, and to prevent noise transmission between the head cover and the plastic silencer. The aim is to improve the

본 고안을 제4도 및 제5도를 참조하여 이하에서 설명한다.The present invention is described below with reference to FIGS. 4 and 5.

헤드커버부(107) 흡입측의 제1헤드커버(13) 위측에 흡입통로(110)와 삽입홈(104)을 갖도록 제2헤드커버(14)를 위치시키고, 상기 헤드커버부(107)의 상부 일측은 토출체적(111)을 형성하고 타측의 삽입홈(104) 및 흡입통로(110)에는 플라스틱소음기(100)가 삽입된다.The second head cover 14 is positioned to have a suction passage 110 and an insertion groove 104 above the first head cover 13 on the suction side of the head cover unit 107. The upper side forms a discharge volume 111 and the plastic silencer 100 is inserted into the insertion groove 104 and the suction passage 110 on the other side.

그리고, 상기 플라스틱소음기(100)의 입구부(101)로 흡입된 냉매가스를 헤드커버부(107)로 안내하는 안내유로(108)와, 상기 흡입통로(110)의 수용부(112)에 고정을 위한 돌기부(103)가 형성되었다.In addition, the guide passage 108 for guiding the refrigerant gas sucked into the inlet portion 101 of the plastic silencer 100 to the head cover portion 107 and fixed to the receiving portion 112 of the suction passage 110. Protrusions 103 were formed.

도면중 미설명 부호 102는 공동부를 나타낸다.In the figure, reference numeral 102 denotes a cavity.

이와같이 구성된 상태에서 크랭크샤프트에 의해 동력을 전달받은 피스톤이 직선 왕복운동을 하게 되면 이에 의해 발생된 흡입력으로 냉매가 흡입되게 되는데 냉매가스가 플라스틱소음기(100)의 입구부(101)를 통해 헤드커버부(107)내로 들어와 실린더로 들어가게 된다. 이때 냉매가스는 플라스틱소음기(100)내에 형성된 안내유로(108)에 의해 실린더로 이동되게 되며 냉매가스 공동부(102)로서 소음이 저감된다.In this configuration, when the piston transmitted power by the crankshaft linearly reciprocates, the refrigerant is sucked by the suction force generated by the piston, and the refrigerant gas passes through the head cover part through the inlet portion 101 of the plastic silencer 100. It enters 107 and enters the cylinder. At this time, the refrigerant gas is moved to the cylinder by the guide passage 108 formed in the plastic silencer 100, and the noise is reduced as the refrigerant gas cavity 102.

또한 플라스틱소음기(100)는 헤드커버부(107) 내측에 결합되어 따로 융착할 필요도 없으며, 헤드커버와 플라스틱소음기가 이중으로 덮혀 있으므로 소음투과를 방지하여 소음을 저감시키게 되는 것이다.In addition, the plastic silencer 100 is coupled to the inside of the head cover portion 107, and does not need to be fused separately, so that the head cover and the plastic silencer are double-covered to reduce noise by preventing noise transmission.

이상에서 살펴본 바와같은 본 고안은 헤드커버부의 제1헤드커버와 제2헤드커버의 위치에 의해 흡입유로를 형성하게 되므로 제조작업이 용이하게 되고 재료비가 절감되는 효과가 있다.The present invention as described above, since the suction flow path is formed by the position of the first head cover and the second head cover of the head cover part, the manufacturing operation is easy and the material cost is reduced.

그리고 헤드커버부(107)내의 헤드커버 강판에 플라스틱소음기(100)가 설치되어 있어 전동부로 부터의 열전달을 방지하고 열손실을 줄임으로써 압축기의 효율을 향상시킬 수 있는 고안이다.In addition, the plastic silencer 100 is installed on the head cover steel plate in the head cover part 107 to prevent heat transfer from the electric part and to reduce heat loss, thereby improving the efficiency of the compressor.
