한편, 상기 어큐뮬레이터(15) 내의 상부측에는 어큐뮬레이터(15) 내부로 유입된 냉매에 포함된 이물질을 걸러내는 스크린어셈(18)이 구비된다. 상기 스크린어셈(18)은 도 2a 및 도 2b에 도시된 바와 같이 상향으로 만곡진 망체 형태의 스크린(18A)과, 상기 스크린(18A)을 지지 및 고정하는 스크린홀더(18B)로 구성되어 있고, 상기 스크린홀더(18B)의 평면상에는 수개의 흡입공(18C)이 형성되어 있다. 그리고 스크린홀더(18B)의 흡입공(18C) 하부측에는 흡입관(14)가 위치하는 것으로, 도 3에 도시된 바와 같이 어큐뮬레이터(15) 내부로 유입된 냉매중에 이물질은 상향으로 만곡진 망 형태의 스크린(18A)에 의해서 걸러지고, 상기 스크린(18A)을 통과한 냉매는 스크린홀더(18B)에 형성된 흡입공(18C)을 통과하게 된다. 이때 상기 스크린홀더(18B)의 흡입공(18C)을 통과한 냉매중에 액냉매는 어큐뮬레이터(15) 내의 하부측으로 낙하되고 기체상태의 냉매만 압축을 위해 흡입관(14)로 유입되도록 하고 있다.On the other hand, the upper side in the accumulator 15 is provided with a screen assembly 18 for filtering foreign matter contained in the refrigerant introduced into the accumulator 15. The screen assembly 18 is composed of a screen 18A having a curved mesh shape upward as shown in Figs. 2A and 2B, and a screen holder 18B for supporting and fixing the screen 18A. Several suction holes 18C are formed on the plane of the screen holder 18B. In addition, the suction pipe 14 is positioned at the lower side of the suction hole 18C of the screen holder 18B. As illustrated in FIG. 3, the foreign matter in the refrigerant introduced into the accumulator 15 is upwardly curved. The refrigerant filtered by 18A and passed through the screen 18A passes through the suction hole 18C formed in the screen holder 18B. At this time, in the refrigerant passing through the suction hole 18C of the screen holder 18B, the liquid refrigerant falls to the lower side in the accumulator 15, and only the gaseous refrigerant is introduced into the suction pipe 14 for compression.

그러나 이러한 종래의 밀폐형 회전식 압축기의 액냉매 유입방지장치는 가스냉매 및 액냉매가 유입되어 나오는 흡입공 하부측에 흡입관이 위치하고 있어 상기 흡입관을 통한 가스냉매 및 액냉매와의 혼입으로 인해 압축기구부의 유막 파괴 및 이상 마모현상이 발생되는 문제점이 있었다. 또한 상기에서와 같은 가스냉매 및 액냉매의 혼입을 방지하기 위해 흡입관의 높이를 올려 설치하게 되면 스크린홀더와 흡입파이프 간의 공간이 협소해져 유로저항의 증대에 따른 흡입손실을 가져오게 됨은 물론 체적공간의 축소로 성능 및 효율이 저하되는 문제점이 있었다. 따라서 본 발명의 목적은 스크린홀더와 흡입파이프 간의 공간 및 체적공간을 축소하지 않으면서 흡입관을 통한 가스냉매 및 액냉매와의 혼입을 방지하는데 있다.However, the liquid refrigerant inflow preventing device of the conventional hermetic rotary compressor has a suction pipe located at the lower side of the suction hole through which the gas refrigerant and the liquid refrigerant flow in, and thus the oil film of the compression mechanism due to the mixing with the gas refrigerant and the liquid refrigerant through the suction pipe. There was a problem that fracture and abnormal wear phenomenon occurs. In addition, in order to prevent the mixing of gas refrigerant and liquid refrigerant as described above, if the height of the suction pipe is installed up, the space between the screen holder and the suction pipe becomes narrow, resulting in suction loss due to the increase in flow resistance, as well as the volumetric space. There was a problem that the performance and efficiency is reduced by reduction. Therefore, an object of the present invention is to prevent the mixing of gas refrigerant and liquid refrigerant through the suction pipe without reducing the space and volume space between the screen holder and the suction pipe.
