상기 흡입관조립체(16)와 그 흡입관조립체(16)에 삽입되어 실린더의 흡입구(5b)에 결합되는 흡입관(12)사이에 압축기구부를 구성하는 실린더(5)를 용접에 의해 밀폐용기(1)에 고정 결합시 압축기구부내로 침투되는 용접 전류가 접지부로 흐르도록 하는 접촉부(17)가 형성된다. 상기 접촉부(17)는 그 일예로 흡입관조립체(16)에 삽입되는 흡입관(12)의 일측에 한 개 이상 돌출 형성된 돌기로 이루어진다. 상기 흡입관(12)에 형성된 돌기는 흡입관조립체의 연결관부(16b) 내주면에 접촉 지지된다.Between the suction pipe assembly 16 and the suction pipe assembly 16 inserted into the suction pipe assembly 16 and coupled to the suction port 5b of the cylinder, the cylinder 5 constituting the compression mechanism is welded to the sealed container 1 by welding. In the fixed coupling, a contact portion 17 is formed so that a welding current penetrating into the compression mechanism portion flows to the ground portion. For example, the contact part 17 may include a protrusion formed at one or more protrusions on one side of the suction pipe 12 inserted into the suction pipe assembly 16. The protrusion formed on the suction pipe 12 is in contact with and supported on the inner circumferential surface of the connection pipe part 16b of the suction pipe assembly.

The protrusion protrudes from the inner circumferential surface of the connection pipe part 16b of the suction pipe assembly into which the suction pipe 12 is inserted, and is supported in contact with the outer circumferential surface of the suction pipe 12.
또한 상기 접촉부의 또다른 일예로, 도 6에 도시한 바와 같이, 흡입관(12)의 외주면에 돌출 형성된 돌기와 상기 흡입관(12)이 삽입되는 흡입관조립체(16)의 연결관부내주면에 돌출 형성된 돌기로 이루어지며 상기 돌기들은 흡입관(12)과 흡입관조립체(16)를 접촉 지지하게 된다.In addition, as another example of the contact portion, as shown in Figure 6, the protrusion formed on the outer peripheral surface of the suction pipe 12 and the protrusion formed on the inner peripheral surface of the connection pipe portion of the suction pipe assembly 16 into which the suction pipe 12 is inserted. The protrusions contact and support the suction pipe 12 and the suction pipe assembly 16.
이하, 본 발명의 밀폐형 회전식 압축기 소부발생 방지구조의 작용효과를 설명하면 다음과 같다.Hereinafter, the operational effects of the closed type rotary compressor burnout prevention structure of the present invention will be described.
먼저 전동기구부 및 압축기구부가 조립된 조립체가 밀폐용기(1)내에 삽입된 상태에서 압축기구부를 구성하는 실린더(5)를 3점 용접에 의해 밀폐용기(1)에 고정 결합하게 된다. 상기 용접은 밀폐용기(1)를 접지(EARTH)시키고 밀폐용기(1)의 용접부에 용접봉을 접촉시킴에 의해 압축기구부를 구성하는 실린더(5)를 밀폐용기(1)내에 용접하게 된다. 상기 실린더(5)를 밀폐용기(1)에 용접하는 과정에서 용접봉을 통하는 용접 전류가 모두 접지부로 직접 흐르지 못하고 용접 전류의 일부가 압축기구부로 침투하게 되면 그 침투된 용접 전류가 압축기구부를 구성하는 실린더(5)의 흡입구(5b)에 삽입된 흡입관(12)을 거쳐 접촉부를 통해 밀폐용기에 고정 결합된 흡입관조립체(16)로 흐르면서 밀폐용기(1)에 접지된 접지부로 흐르게 된다. 이와 같이압축기구부로 침투된 용접 전류가 접촉부(17)를 통해 폐회로를 이루면서 흐르게 되므로 압축기구부를 구성하는 부품의 스파크로 인한 소부 발생을 억제하게 되며 아울러 용접 상태를 보다 개선시키게 된다.First, the cylinder 5 constituting the compression mechanism part is fixedly coupled to the sealed container 1 by three-point welding in a state where the assembly of the electric mechanism part and the compression mechanism part is inserted into the sealed container 1. The welding causes the sealed container 1 to be welded to the sealed container 1 by grounding the sealed container 1 and bringing the welding rod into contact with the welding part of the sealed container 1. In the process of welding the cylinder 5 to the hermetic container 1, if all the welding current through the welding rod does not flow directly to the ground portion and part of the welding current penetrates into the compression mechanism, the penetrated welding current constitutes the compression mechanism. It flows through the suction pipe 12 inserted into the suction port 5b of the cylinder 5 to the suction pipe assembly 16 fixedly coupled to the airtight container through the contact part, and flows to the ground part grounded in the airtight container 1. In this way, the welding current penetrated into the compression mechanism part flows while forming a closed circuit through the contact part 17, thereby suppressing the occurrence of burning due to sparks of the parts constituting the compression mechanism part, and further improving the welding state.
이상에서 설명한 바와 같이, 본 발명에 의한 밀폐형 회전식 압축기의 소부발생 방지구조는 압축기구부를 구성하는 실린더를 용접에 의해 밀폐용기에 고정 결합하는 과정에서 용접 전류의 일부가 압축기구부로 침투될 경우 그 침투된 용접 전류가 밀폐용기를 통해 접지부로 흐르도록 하여 압축기구부를 구성하는 부품들의 스파크로 인한 소부 발생을 방지하게 됨으로써 부품의 파손을 방지하게 될 뿐만 아니라 조립 상태를 견고하게 할 수 있는 효과가 있다.As described above, the seizure prevention structure of the hermetic rotary compressor according to the present invention is penetrated when a part of the welding current penetrates into the compressor sphere in the process of fixing the cylinder constituting the compressor sphere to the sealed container by welding. The welding current flows to the ground part through the sealed container, thereby preventing occurrence of burning due to sparks of the parts constituting the compression mechanism, thereby preventing damage to the parts and strengthening the assembled state.
