상기 고저압 분리부재(80)와 원통체(50) 그리고 상부캡(70)이 결합되는 구조는, 도 4에 도시한 바와 같이, 원통체(50)의 단부에 다단으로 단턱진 제1 결합부(A)가 형성되고 상기 고저압 분리부재(80)의 단부에 상기 제1 결합부(A)에 상응하도록 다단으로 형성된 제2 결합부(B)가 되어 그 제2 결합부(B)가 원통체(50)의 제1 결합부(A)에 밀착되도록 얹혀지며 상기 상부캡(70)의 하단면(71)이 고저압 분리부재(80)의 돌기부(81) 상면에 얹혀지고 상기 원통체(50)와 고저압 분리부재(80) 그리고 상부캡(70)의 영역을 공유하도록 용접부(90)가 접합된다. 상기 원통체(50)의 내경 및 두께는 상부캡(70)의 내경 및 두께와 동일하도록 형성된다.The high and low pressure separating member 80, the cylindrical body 50 and the upper cap 70 is coupled to the structure, as shown in Figure 4, the first coupling portion stepped in multiple stages at the end of the cylindrical body 50 (A) is formed and the second coupling portion (B) is formed in the second coupling portion (B) formed in multiple stages to correspond to the first coupling portion (A) at the end of the high and low pressure separating member (80) is a cylindrical The lower surface 71 of the upper cap 70 is mounted on the upper surface of the protrusion 81 of the high and low pressure separating member 80 and the cylindrical body (20) is mounted to be in close contact with the first coupling portion A of the sieve 50. The welding portion 90 is joined so as to share the region of the 50 and the high and low pressure separating member 80 and the upper cap 70. The inner diameter and thickness of the cylindrical body 50 is formed to be the same as the inner diameter and thickness of the upper cap (70).
상기 원통체(50)의 제1 결합부(A)는 원통체(50)의 상단면의 일부면에 해당되는 제1 상단 접촉면부(51)와 상기 제1 상단 접촉면부(51)에 수직으로 연장 형성된 제1 수직 접촉면부(52)와 상기 제1 수직 접촉면부(52)에 수평으로 연장 형성된 제1 하단 접촉면부(53)로 형성된다.The first coupling portion A of the cylindrical body 50 is perpendicular to the first upper contact surface 51 and the first upper contact surface 51 corresponding to a part of the upper surface of the cylindrical body 50. The first vertical contact surface 52 is formed to be extended and the first lower contact surface 53 is formed to extend horizontally to the first vertical contact surface 52.
그리고 상기 고저압 분리부재(80)의 제2 결합부는 일정 두께와 폭을 갖도록 형성된 돌기부(81)와 상기 돌기부(81)의 하면에 상기 제1 수직 접촉면부(52)의 면적과 상응하도록 연장 형성된 제2 수직 접촉면부(82)와 상기 제2 수직 접촉면부(82)에 수평으로 연장 형성된 제2 하단 접촉면부(83)로 형성된다.The second coupling portion of the high and low pressure separating member 80 extends to correspond to the area of the first vertical contact surface 52 on the protrusion 81 and the lower surface of the protrusion 81 formed to have a predetermined thickness and width. The second vertical contact surface portion 82 and the second vertical contact surface portion 82 may be formed of a second lower contact surface portion 83 extending horizontally.
상기 고저압 분리부재(80)는 그 제2 결합부(B)가 원통체(50)의 제1 결합부(A)에 형합된다. 즉 고저압 분리부재(80)의 돌기부(81)가 제1 결합부(A)의 제1 상단 접촉면부(51)에 얹혀짐과 아울러 제2 수직 접촉면부(82)가 제1 수직 접촉면부(52)에 접촉되고 또한 제2 하단 접촉면부(83)가 제1 하단 접촉면부(53)에 접촉되도록 형합된다. 그리고 상기 돌기부(81)의 상면에 상부캡(70)의 하단면이 얹혀진 상태에서 용접하게 된다. 상기 용접부(90)는 원통체(50)와 고저압 분리부재(80) 그리고 상부캡(70)의 영역을 포함하도록 이루어진다.In the high and low pressure separating member 80, the second coupling part B is joined to the first coupling part A of the cylindrical body 50. That is, the protrusion 81 of the high and low pressure separating member 80 is mounted on the first upper contact surface 51 of the first engaging portion A, and the second vertical contact surface 82 is the first vertical contact surface ( 52) and the second bottom contact surface portion 83 is shaped to contact the first bottom contact surface portion 53. The lower surface of the upper cap 70 is welded on the upper surface of the protrusion 81. The weld 90 includes a cylindrical body 50, a high and low pressure separating member 80, and an area of the upper cap 70.
이하, 본 발명의 압축기 밀폐용기 조립구조의 작용효과를 설명하면 다음과 같다.Hereinafter, the operational effects of the compressor sealed container assembly structure of the present invention will be described.
먼저 압축기는 전원이 인가되어 전동기구부(M)에서 구동력을 발생시키게 되면 그 구동력을 전달받아 압축기구부(P)가 작동하면서 냉매 가스를 흡입하고 압축하여 토출시키게 된다. 이와 같은 과정이 지속되는 과정에서 상기 밀폐용기(V)의 내부는 외부보다 상대적으로 압력이 높은 상태가 될 뿐만 아니라 밀폐용기(V)의 일측에 결합된 토출관(91)이 위치하는 토출 영역은 고압 상태가 된다. 내부가 고압 상태인 밀폐용기(V)의 상부캡(70)과 고저압 분리부재(80) 그리고 원통체(50)의 결합부분은 원통체(50)의 제1 결합부(A)와 고저압 분리부재(80)의 제2 결합부(B)가 3개의 밀착면에 의해 접촉된 상태가 되므로 압력이 누설되는 패스(Path)가 복잡하여 압력 누설을 최소화시키게 된다. 즉, 밀폐용기(V) 내부의 압력이 누설될 경우 그 경로는 제1 하단 접촉면부(53)와 제2 하단 접촉면부(83)사이 그리고 제1,2 수직 접촉면부(52)(82)사이 그리고 돌기부(81)의 하면과 제1 상단 접촉면부(51)사이로 이루어지게 되므로 가스 유로가 복잡할 뿐만 아니라 접촉면적이 넓게 되어 압력 누설을 최소화시키게 된다.First, when the power is applied to generate a driving force in the electric mechanism (M), the driving force is received and the compression mechanism (P) operates while inhaling, compressing and discharging the refrigerant gas. As the process continues, the inside of the sealed container V is not only relatively high in pressure than the outside, but also the discharge region in which the discharge pipe 91 coupled to one side of the sealed container V is located. It is in a high pressure state. The coupling portion of the upper cap 70, the high and low pressure separating member 80, and the cylindrical body 50 of the sealed container V inside the high pressure state is the first coupling portion A and the high low pressure of the cylindrical body 50. Since the second coupling portion B of the separating member 80 is in contact with the three contact surfaces, a path through which pressure leaks is complicated, thereby minimizing pressure leakage. That is, when the pressure inside the sealed container V leaks, the path is between the first lower contact surface portion 53 and the second lower contact surface portion 83 and between the first and second vertical contact surface portions 52 and 82. In addition, since the bottom surface of the protrusion part 81 and the first upper contact surface part 51 are formed, the gas flow path is complicated and the contact area is widened to minimize the pressure leakage.
특히, 원통체(50)와 고저압 분리부재(80) 그리고 상부캡(70)을 접합시키는 용접 가공시 용접이 불량하게 될 경우에도 압력이 누설되는 패스가 복잡하게 되어 압력 누설이 최소화된다.In particular, in the welding process in which the cylindrical body 50, the high and low pressure separating member 80, and the upper cap 70 are welded, even if the welding becomes poor, the pressure leakage path is complicated, thereby minimizing the pressure leakage.
이상에서 설명한 바와 같이, 본 발명에 의한 압축기의 밀폐용기 조립구조는 내부가 고온 고압 상태를 유지하는 밀폐용기에서 그 밀폐용기를 구성하는 부품들을 용접에 의해 조립할 때 용접 불량이 발생하게 될 경우 압축기의 작동시 밀폐용기 내부의 압력이 외부로 누설되는 것을 방지하게 됨으로써 압축기의 압축 성능 저하를 방지하여 압축 효율을 높일 수 있는 효과가 있다.As described above, the sealed container assembly structure of the compressor according to the present invention in the sealed container that maintains the high temperature and high pressure state when the welding failure occurs when assembling the components constituting the sealed container by welding of the compressor Since the pressure inside the sealed container is prevented from leaking to the outside during operation, the compression performance of the compressor is prevented from being lowered, thereby increasing the compression efficiency.
