이에 도시된 바와 같이, 종래의 리니어 압축기는 저면에 오일이 채워지는 케이싱(V)의 내부에 횡방향으로 설치되어 냉매를 흡입하여 압축 및 토출하는 압축 유니트(C)와, 그 압축 유니트(C)의 외부에 고정되어 미끄럼부에 오일을 공급하는 오일피더(O)로 구성되어 있다.As shown in the drawing, a conventional linear compressor has a compression unit (C) installed in the transverse direction inside a casing (V) filled with oil on a bottom surface thereof to suck, compress, and discharge refrigerant, and the compression unit (C).

An inner stator assembly 4A fixed to the outer circumferential surface of the frame 1 supporting the cylinder 3 and an outer stator assembly 4B fixed with a predetermined gap on the outer circumferential surface of the inner stator assembly 4A; The magnet assembly 5 interposed between the inner and outer stator assemblies 4A and 4B, which constitutes the mover of the linear motor, and is integrally fixed to the magnet assembly 5 so as to slide in the cylinder 3. The inner and outer resonant springs 7A and 7B for inducing and continuously compressing the piston 6 and the magnet assembly 5 to continuously resonate in the air gap between the inner and outer stator assemblies 4A and 4B. Consists of including.
상기 피스톤(6)의 내부에는 냉매유로(6a)가 형성되고, 그 냉매유로(6a)의 선단면에는 흡입밸브(6b)가 장착되며, 그 냉매유로(6a)의 입구측에는 냉매가스의 흡입시 발생된 소음을 제거하는 흡입소음기(10)가 삽입되어 마그네트 조립체(5)에 장착되어 있다.A refrigerant passage 6a is formed inside the piston 6, and a suction valve 6b is mounted at the front end surface of the refrigerant passage 6a, and at the inlet side of the refrigerant passage 6a when suction of refrigerant gas occurs. A suction silencer 10 for removing the generated noise is inserted and mounted in the magnet assembly 5.

도면중 미설명 부호인 8은 토출밸브 조립체, 9는 냉매가스 흡입관이다.In the drawings, reference numeral 8 denotes a discharge valve assembly, and 9 denotes a refrigerant gas suction pipe.
상기와 같이 구성된 종래 리니어 압축기는 다음과 같이 동작된다.The conventional linear compressor configured as described above is operated as follows.
즉, 상기 내 외측 고정자 조립체(4A,4B)로 이루어지는 리니어 모터의 고정자에 전류가 인가되어 유도자기가 발생되면, 상기 고정자 사이에 개재되는 가동자인 마그네트 조립체(5)가 직선 왕복운동을 하게 되어 이에 결합된 피스톤(6)이 실린더(3)의 내부를 직선으로 왕복운동하게 되고, 그 피스톤(6)이 실린더(3)내를 직선으로 왕복운동함에 따라 실린더(3)내의 압력차가 발생되며, 이 실린더(3)내의 압력차에 의해 냉매가스가 냉매가스 흡입관(9)을 통해 흡입소음기(10) 및 피스톤(6)의 냉매유로(6a)로 유입되었다가 실린더(3)로 흡입 압축되어 토출된다.That is, when an electric current is applied to the stator of the linear motor including the inner and outer stator assemblies 4A and 4B to generate an induction magnet, the magnet assembly 5, which is the mover interposed between the stators, performs a linear reciprocating motion. The combined piston 6 reciprocates in the cylinder 3 in a straight line, and as the piston 6 reciprocates in the cylinder 3 in a straight line, a pressure difference in the cylinder 3 is generated. Due to the pressure difference in the cylinder (3), the refrigerant gas flows into the refrigerant passage (6a) of the suction silencer (10) and the piston (6) through the refrigerant gas suction pipe (9), and is sucked into the cylinder (3) and discharged. .
이때, 상기 냉매가스가 피스톤(6)의 흡입밸브(6b) 등을 거쳐 흡입되는 과정에서 소음이 발생하게 되는데, 이 소음은 흡입소음기(10)의 소경부(11) 및 대경부(12)를 거치면서 음향학적 특성에 의해 감쇠되는 것이었다.At this time, noise is generated in the process of the refrigerant gas is sucked through the suction valve (6b) of the piston (6), this noise is the small diameter portion 11 and the large diameter portion 12 of the suction silencer (10) It was attenuated by the acoustic characteristics as it went through.
그러나, 상기와 같은 종래 리니어 압축기에서는 흡입소음기(10)가 피스톤(6)에 체결되어 함께 공진운동을 하게 되므로, 그 흡입소음기(10)의 흡입단과 커버(2)의 냉매통구(2a) 사이에는 상대운동을 위한 틈새(c)가 발생되는데, 이 틈새(c)는 커버(2)의 냉매통구(2a)에 흡입소음기(10)의 흡입단이 내삽되어 커버(2) 외곽측에서 노출되므로 케이싱(C)에 채워지는 냉매가스의 일부가 피스톤(6)의 냉매유로(6a)로 유입되지 않고 상기한 틈새(c)를 통해 커버(2)의 내부공간(V1)으로 스며들게 되고, 이 커버(2)의 내부공간(V1)으로 스며든 냉매가스는 구동모터에 직접 접촉되어 고온으로 가열되었다가 피스톤(6)의 다음 흡입행정시 상기한 틈새(c)를 통해 다시 피스톤(6)의 냉매유로(6a)로 흡입되어 실린더(3)에서 압축되므로 흡입가스의 비체적이 감소하여 압축기의 효율이 저하되는 문제점이 있었다.However, in the conventional linear compressor as described above, since the suction silencer 10 is fastened to the piston 6 and resonates together, the suction silencer 10 is connected between the suction end of the suction silencer 10 and the refrigerant passage 2a of the cover 2. A gap c for a relative movement is generated, which is a casing because the suction end of the suction silencer 10 is inserted into the refrigerant passage 2a of the cover 2 to be exposed from the outside of the cover 2. A portion of the refrigerant gas filled in (C) does not flow into the refrigerant passage 6a of the piston 6 but is permeated into the internal space V1 of the cover 2 through the above-mentioned gap c, and this cover ( The refrigerant gas penetrated into the internal space V1 of 2) is directly contacted with the driving motor and heated to a high temperature, and then the refrigerant flow path of the piston 6 again through the aforementioned clearance c at the next suction stroke of the piston 6. Since it is sucked into 6a and compressed in the cylinder 3, the specific volume of the suction gas is reduced and the efficiency of the compressor is lowered. Had a problem.
본 발명은 상기와 같은 종래 리니어 압축기가 가지는 문제점을 감안하여 안출한 것으로, 케이싱의 내부에 충진되는 냉매가스의 흡입행정시 그 일부가 커버의 내부공간으로 누설되는 것을 방지할 수 있는 리니어 압축기의 흡입손실 저감구조를 제공하려는데 그 목적이 있다.The present invention has been made in view of the above problems of the conventional linear compressor, and the suction of the linear compressor which can prevent a part of leakage into the inner space of the cover during the suction stroke of the refrigerant gas filled in the casing. The purpose is to provide a loss reduction structure.

The refrigerant gas filled in the casing (C) is passed through the refrigerant gas guide pipe 200 and the suction silencer 100 and the refrigerant passage 6a of the piston 6 during the suction stroke of the piston 6. It is sucked into the cylinder 3 and discharged by compression.
이때, 상기 케이싱(C)의 내부에 채워지는 냉매가스를 냉매유로(6a)로 유도하는 냉매가스 안내관(200)의 끝단이 흡입소음기(100)의 대경부(120)에 깊이 내삽되고, 상기 흡입소음기(100)는 피스톤(6)의 냉매유로(6a)에 삽입 장착되어 있으므로, 상기 냉매가스의 흡입방향에 대해 냉매가스 안내관(200)과 흡입소음기(100) 사이에 틈새가 발생되지 않게 되고, 이로 인해 상기 케이싱(C)에 채워졌다가 피스톤(6)의 흡입행정시 냉매가스 안내관(200)을 거쳐 흡입소음기(또는, 피스톤의 냉매유로)(100)로 흡입되는 냉매가스의 누설이 방지되는 것이다.At this time, the end of the refrigerant gas guide pipe 200 for guiding the refrigerant gas filled in the casing C to the refrigerant passage 6a is deeply interpolated in the large diameter portion 120 of the suction silencer 100, Since the suction silencer 100 is inserted into the refrigerant passage 6a of the piston 6, a gap is not generated between the refrigerant gas guide pipe 200 and the suction silencer 100 in the suction direction of the refrigerant gas. Due to this, leakage of the refrigerant gas filled in the casing C and sucked into the suction silencer (or the refrigerant flow path of the piston) 100 through the refrigerant gas guide tube 200 during the suction stroke of the piston 6 is achieved. This is to be avoided.
이렇게, 상기 피스톤의 냉매유로에 흡입측 소음기를 삽입 장착하고, 상기 냉매유로의 흡입측을 복개하는 커버의 흡입구 내측면에 냉매가스 안내관을 체결시키되 그 냉매가스 안내관의 내측단이 흡입측 소음기에 내삽되도록 하게 되면, 상기 피스톤의 흡입행정시 케이싱에 채워졌다가 냉매유로로 흡입되는 냉매가스가 냉매가스 안내관을 통해 소음기로 누설없이 흡입되므로, 냉매가스의 흡입손실이 최소한으로 감소되어 압축기의 효율이 현저하게 향상된다.In this way, the suction side silencer is inserted into the refrigerant passage of the piston and the refrigerant gas guide tube is fastened to the inner side of the suction port of the cover covering the suction side of the refrigerant passage, and the inner end of the refrigerant gas guide tube is the suction side silencer. When it is inserted into the piston, the refrigerant gas filled in the casing during the suction stroke of the piston and sucked into the refrigerant passage is sucked without leakage into the silencer through the refrigerant gas guide tube, so that the suction loss of the refrigerant gas is reduced to a minimum. The efficiency is significantly improved.
본 발명에 의한 리니어 압축기의 흡입소음기 구조는, 피스톤의 냉매유로에 흡입측 소음기를 삽입 장착하고, 상기 냉매유로의 흡입측을 복개하는 커버의 흡입구 내측면에 냉매가스 안내관을 체결시키되 그 냉매가스 안내관의 내측단이 흡입측 소음기에 내삽되도록 함으로써, 상기 피스톤의 흡입행정시 케이싱에 채워졌다가 냉매유로로 흡입되는 냉매가스가 냉매가스 안내관을 통해 소음기로 누설없이 흡입되므로, 냉매가스의 흡입손실이 최소한으로 감소되어 압축기의 효율이 현저하게 향상된다.The suction silencer structure of the linear compressor according to the present invention includes a suction silencer inserted into a refrigerant passage of a piston and fastening a refrigerant gas guide tube to an inner side of a suction port of a cover covering the suction side of the refrigerant passage. By allowing the inner end of the guide tube to be inserted into the suction side silencer, the refrigerant gas filled in the casing during suction operation of the piston and sucked into the refrigerant passage is sucked without leakage into the silencer through the refrigerant gas guide tube. The loss is reduced to a minimum, which significantly improves the efficiency of the compressor.
