도 1은 고압방식의 밀폐형 압축기의 일예를 도시한 것으로, 이에 도시한 바와 같이, 상기 밀폐형 압축기는 밀폐용기(10)와 그 밀폐용기(10)의 내부에 장착되는 전동기구부(20)와 상기 전동기구부(20)의 구동력을 전달받아 가스를 압축하는 압축기구부(30)와 상기 밀폐용기(10)의 측부에 위치하도록 그 밀폐용기(10)와 연결관(40)에 의해 연결되어 상기 압축기구부(30)로 액냉매의 유입을 방지하는 어큐뮬레이터(50)를 포함하여 구성된다.1 shows an example of a hermetic compressor of a high pressure type. As shown in FIG. 1, the hermetic compressor includes a hermetic container 10 and an electric mechanism 20 mounted inside the hermetic container 10 and the electric motor. The compression mechanism (30) and the compression vessel (30) for compressing the gas received by the driving force of the mechanism portion 20 is connected to the compression vessel (10) and the connecting tube (40) so as to be located on the side of the sealed container (10). 30) is configured to include an accumulator (50) for preventing the introduction of the liquid refrigerant.

한편, 상기 어큐뮬레이터(50)는 소정의 내부 공간을 갖는 원통 형태로 형성됨과 아울러 상기 연결관(40)의 일부가 내부에 소정의 길이로 위치하는 어큐뮬레이터 용기(51)와, 상기 어큐뮬레이터 용기(51)의 타측에 증발기(미도시)와 연결되는 냉매관(52)과, 상기 어큐뮬레이터 용기(51)의 내측에 위치하는 연결관(40)의 끝 상측에 위치하도록 상기 어큐뮬레이터 용기(51)에 장착되어 상기 냉매관(52)을 통해 어큐뮬레이터 용기(51)내로 유입되는 냉매에 섞여 있는 오일 및 이물질을 필터링하는 스크린(53) 및 그 스크린(53)을 어큐뮬레이터 용기(51) 내부에 고정시키는 스크린 홀더(54)를 포함하여 구성되어 있다.On the other hand, the accumulator 50 is formed in a cylindrical shape having a predetermined internal space, the accumulator container 51 and a portion of the connecting pipe 40 is located in a predetermined length therein, and the accumulator container 51 A refrigerant pipe 52 connected to an evaporator (not shown) on the other side of the accumulator, and mounted on the accumulator container 51 so as to be positioned above an end of the connection pipe 40 located inside the accumulator container 51; The screen 53 for filtering oil and foreign matter mixed in the refrigerant flowing into the accumulator container 51 through the refrigerant pipe 52 and the screen holder 54 for fixing the screen 53 to the inside of the accumulator container 51. It is configured to include.

상기 어큐뮬레이터(50)를 거친 가스를 상기 밀폐용기(10)내의 압축기구부(30)로 안내하는 연결관(40)은 일정 내경을 갖는 밴딩된 관으로 이루어진다.The connecting pipe 40 for guiding the gas passed through the accumulator 50 to the compression mechanism 30 in the hermetic container 10 is formed of a bent tube having a predetermined inner diameter.

미설명 부호 60은 어큐뮬레이터(50)를 상기 밀폐용기(10)에 고정하는 고정밴드이고, 61은 밀폐용기(10)를 지지하는 베이스판이다.Reference numeral 60 is a fixing band for fixing the accumulator 50 to the hermetic container 10, 61 is a base plate for supporting the hermetic container 10.

상기한 바와 같은 밀폐형 압축기의 작동은 먼저 전동기구부(20)의 구동력이 상기 압축기구부(30)에 전달되어 압축기구부(30)가 작동하게 되면 그 압축기구부(30)의 주기적인 체적변화 및 밸브의 작동에 의한 흡입력에 의해 증발기를 거친 냉매가 냉매관(52)을 통해 어큐뮬레이터 용기(51)로 유입된다.In the operation of the hermetic compressor as described above, the driving force of the electric mechanism unit 20 is first transmitted to the compression mechanism unit 30 so that the compression mechanism unit 30 is operated. The refrigerant passing through the evaporator is introduced into the accumulator vessel 51 through the refrigerant pipe 52 by the suction force caused by the operation.

상기 어큐뮬레이터 용기(51)로 유입되는 냉매는 상기 스크린(53)을 거치면서 냉매 중에 섞여 있는 이물질 및 액체 상태의 냉매가 필터링되고 그 스크린(53)을 거친 가스 상태의 냉매가 연결관(40)을 통해 압축기구부(30)로 유입된다. 상기 압축기구부(30)로 흡입되는 냉매 가스는 그 압축기구부(30)에서 압축되어 토출되며 그 토출되는 냉매 가스는 상기 밀폐용기(10)의 일측에 결합된 토출관(11)을 통해 응축기로 유입된다.As the refrigerant flowing into the accumulator container 51 passes through the screen 53, foreign substances mixed in the refrigerant and the refrigerant in a liquid state are filtered out, and the refrigerant in the gas state passing through the screen 53 passes through the connection pipe 40. Through the compression mechanism 30 is introduced.

그러나 상기한 바와 같은 종래 구조는 밀폐용기(10) 내부에 장착된 압축기구부(30)에서 주기적인 체적변화와 밸브의 작동에 의해 가스를 흡입하고 압축하여 토출시키는 과정에서 압력 맥동 및 밸브 개폐에 의한 진동 소음이 발생되며 그 압력 맥동 및 진동 소음은 상기 연결관(40)을 통해 어큐뮬레이터(50)에 전달되면서 그 어큐뮬레이터(50)를 가진시켜 진동에 의해 소음을 유발시키게 되는 문제점이 있었다.However, the conventional structure as described above is due to the pressure pulsation and the valve opening and closing in the process of inhaling, compressing and discharging the gas by the periodic volume change and the operation of the valve in the compression mechanism 30 mounted inside the sealed container 10. Vibration noise is generated, and the pressure pulsation and vibration noise are transmitted to the accumulator 50 through the connecting pipe 40, causing the accumulator 50 to cause noise by vibration.

상기한 바와 같은 점을 감안하여 안출한 본 발명의 목적은 밀폐용기내부에장착된 압축기구부에서 가스를 흡입하고 압축하여 토출시키는 과정에서 발생되는 압력 맥동 및 밸브 개폐에 의한 진동이 어큐뮬레이터로 전달되는 것을 최소화할 뿐만 아니라 상기 어큐뮬레이터에서 발생되는 압력 맥동이 상기 밀폐용기측으로 전달되는 것을 최소화할 수 있도록 한 밀폐형 압축기의 진동 저감구조를 제공함에 있다.The object of the present invention devised in view of the above point is that the vibration caused by pressure pulsation and valve opening and closing generated in the process of sucking, compressing and discharging gas from a compression mechanism mounted in an airtight container is transmitted to the accumulator. In addition to minimizing, it is to provide a vibration reducing structure of the hermetic compressor to minimize the pressure pulsation generated in the accumulator to the sealed container side.

먼저, 상기 밀폐형 압축기는 전원이 인가됨에 따라 상기 전동기구부(20)가 구동되면서 구동력을 발생시키게 되면 그 전동기구부(20)의 구동력이 상기 압축기구부(30)에 전달되어 압축기구부(30)가 작동하게 된다. 상기 압축기구부(30)가 작동함에 따라 주기적인 체적변화 및 밸브의 작동에 의한 흡입력에 의해 증발기를 거친 냉매가 어큐뮬레이터(50)로 유입되며 그 어큐뮬레이터(50)로 유입된 냉매는 그 어큐뮬레이터(50)를 거치면서 이물질과 액 냉매가 여과되면서 기체 상태의 냉매로 상기 진동 흡수형 연결관(70)을 통해 상기 밀폐용기(10) 내부에 장착된 압축기구부(30)로 흡입된다. 상기 압축기구부(30)로 흡입되는 냉매 가스는 그 압축기구부(30)에서 압축되어 토출되며 그 토출되는 냉매 가스는 상기 밀폐용기(10)의 일측에 결합된 토출관(11)을 통해 응축기로 유입된다.First, when the hermetic compressor generates a driving force while the power mechanism 20 is driven as power is applied, the driving force of the power mechanism 20 is transmitted to the compressor mechanism 30 to operate the compressor mechanism 30. Done. As the compression mechanism 30 is operated, the refrigerant passing through the evaporator flows into the accumulator 50 due to the periodic volume change and the suction force by the operation of the valve, and the refrigerant introduced into the accumulator 50 is the accumulator 50. While passing through the foreign matter and the liquid refrigerant is filtered through the vibration-absorbing connection tube 70 as a refrigerant in the gas state is sucked into the compression mechanism (30) mounted inside the sealed container (10). The refrigerant gas sucked into the compression mechanism (30) is compressed and discharged from the compression mechanism (30), and the discharged refrigerant gas flows into the condenser through a discharge pipe (11) coupled to one side of the sealed container (10). do.

그리고 상기 압축기구부(30)에서 주기적인 체적변화와 밸브의 작동에 의해 가스를 흡입하고 압축하여 토출시키는 과정에서 압력 맥동 및 밸브 개폐에 의한 진동이 발생되며 그 발생되는 압력 맥동 및 밸브 개폐에 의한 진동이 상기 진동 흡수형 연결관(70)을 통해 어큐뮬레이터(50)로 전달되는 과정에서 그 진동 흡수형 연결관(70)에 구비된 주름관부(72)(72')(72")에 의해 진동이 흡수된다. 아울러 상기 어큐뮬레이터(50)로 냉매가 유입되고 유출되는 과정에서 발생되는 압력 맥동에 의한진동이 상기 진동 흡수형 연결관(70)을 통해 밀폐용기(10)로 전달되는 과정에서 그 진동 흡수형 연결관(70)에 구비된 주름관부(72)(72')(72")에 의해 흡수된다.And in the process of inhaling, compressing and discharging the gas by the periodic volume change and the operation of the valve in the compression mechanism 30, the vibration caused by the pressure pulsation and the valve opening and closing is generated and the vibration caused by the pressure pulsation and valve opening and closing In the process of being transmitted to the accumulator 50 through the vibration absorbing connector 70, the vibration is absorbed by the corrugated pipe parts 72, 72 ′, 72 ″ provided in the vibration absorbing connector 70. In addition, vibration caused by pressure pulsation generated in the refrigerant flowing into and out of the accumulator 50 is transmitted to the sealed container 10 through the vibration absorbing connection pipe 70. It is absorbed by the corrugated pipe portions 72, 72 'and 72 "provided in the connection pipe 70.

이상에서 설명한 바와 같이, 본 발명에 의한 밀폐형 압축기의 진동 저감구조는 밀폐용기내부에 장착된 압축기구부에서 가스를 흡입하고 압축하여 토출시키는 과정에서 발생되는 압력 맥동 및 밸브 개폐에 의한 진동이 어큐뮬레이터로 전달되는 것을 최소화하게 될 뿐만 아니라 상기 어큐뮬레이터에서 발생되는 압력 맥동이 상기 밀폐용기측으로 전달되는 것을 최소화하게 됨으로써 진동에 의한 소음 발생을 억제하여 신뢰성을 높일 수 있는 효과가 있다.As described above, in the vibration reduction structure of the hermetic compressor according to the present invention, the pressure pulsation generated during the process of sucking, compressing and discharging the gas from the compression mechanism mounted in the hermetic container is transmitted to the accumulator. In addition to minimizing the noise, the pressure pulsation generated in the accumulator is minimized to be transmitted to the airtight container, thereby suppressing the generation of noise due to vibration, thereby increasing reliability.
