본 발명은 밀폐형 압축기에 관한 것으로, 보다 구체적으로는 로터리 압축기의 인렛튜브(inlet tube)에 관한 것이다.The present invention relates to a hermetic compressor, and more particularly to an inlet tube of a rotary compressor.

일반적으로 에어컨 등에 적용되는 밀폐형 압축기는 케이싱의 내부에 전동기구부와 압축기구부가 함께 마련되어 기계적에너지를 냉매의 압축에너지로 전환하는 것이다.In general, a hermetic compressor applied to an air conditioner is provided with an electric mechanism part and a compression mechanism part inside the casing to convert mechanical energy into compressed energy of a refrigerant.

상기 밀폐형 압축기는 그 압축방식에 따라 왕복동식, 로터리식, 스크롤식, 베인식 등으로 구분할 수 있다. 이 중 상기 로터리식 압축기(이하, 로터리 압축기로 약칭함)는 환형으로 형성되어 밀폐된 케이싱의 내부에 설치되는 실린더와, 상기 실린더의 내부 공간에서 편심 회전하면서 직선운동을 하는 베인과 함께 냉매가스를 압축하는 롤링피스톤으로 이루어져 있다.The hermetic compressor may be classified into a reciprocating type, a rotary type, a scroll type and a vane type according to the compression method. Among these, the rotary compressor (hereinafter, abbreviated as rotary compressor) is formed in an annular shape and installed inside the sealed casing, and the refrigerant gas together with the vane for linear movement while eccentrically rotating in the inner space of the cylinder. It consists of a rolling piston that compresses.

이러한 로터리 압축기는 그 실린더의 흡입홀에 인렛튜브가 삽입되어 결합되고, 그 인렛튜브는 상기 케이싱의 외부에 구비되어 액냉매와 가스냉매를 분리하는 어큐뮬레이터의 연결관과 용접 결합되어 있다.The rotary compressor is coupled to the inlet tube is inserted into the suction hole of the cylinder, the inlet tube is provided on the outside of the casing is welded to the connecting tube of the accumulator separating the liquid refrigerant and gas refrigerant.

상기와 같은 종래 로터리 압축기의 인렛튜브는, 용접성을 고려하여 상기 어큐뮬레일의 연결관과 동일한 재질인 동관으로 형성됨에 따라 타발삽입시 변형될 우려가 있으므로 종래에는 통상 칼라라고 하는 고정용 파이프를 상기 인렛튜브의 내측에 삽입한 후 지그 등으로 상기 칼라를 압입하여 상기 인렛튜브가 상기 실린더의 흡입홀에 긴밀하게 삽입되도록 하는 것이었다. Since the inlet tube of the conventional rotary compressor is formed of a copper tube made of the same material as the connecting tube of the accumulator in consideration of weldability, there is a possibility that the inlet tube may be deformed during insertion. After inserting into the inlet tube, the collar was press-fitted with a jig or the like so that the inlet tube was tightly inserted into the suction hole of the cylinder.

그러나, 이는 별도의 부재, 즉 칼라를 사용함에 따라 그만큼 부품수가 증가하여 생산비용이 증가하게 될 뿐만 아니라, 상기 칼라를 인렛튜브의 내부에 압입하는 과정에서 압입력이 과도할 경우에는 상기 인렛튜브가 손상될 수 있고 반대로 압입력이 너무 작으면 냉매의 누설이 발생하는 등 조립공정이 난해하여 생산성이 저하되는 문제점이 있다.However, this increases the production cost by increasing the number of parts according to the use of a separate member, that is, the collar, as well as the inlet tube when the pressing force is excessive in the process of pressing the collar into the inlet tube. On the contrary, if the pressure input is too small, the assembly process is difficult, such as leakage of refrigerant, and thus there is a problem in that productivity is lowered.

본 발명은 상술한 문제점을 해결한 것으로서, 별도의 고정용 파이프를 사용하지 않고도 상기 인렛튜브를 상기 실린더의 흡입홀에 긴밀하게 삽입할 수 있어 생산비용을 절감하고 생산성을 높일 수 있는 밀폐형 압축기를 제공하는데 목적이 있다.The present invention solves the above-mentioned problems, it is possible to insert the inlet tube into the suction hole of the cylinder tightly without using a separate fixing pipe to provide a hermetic compressor that can reduce production costs and increase productivity The purpose is to.

There is provided a hermetic compressor, characterized in that a true coupling is formed.

또, 밀폐된 내부공간을 가지는 케이싱; 상기 케이싱의 내부공간에 설치되어 압축공간을 형성하고 그 압축공간에 연통되도록 흡입홀이 형성되는 실린더; 상기 실린더의 압축공간에 연통되도록 연결관이 구비되어 상기 케이싱의 외부에 설치되는 어큐뮬레이터; 및 상기 실린더의 흡입홀에 요철 결합되어 상기 어큐뮬레이터의 연결관에 연결되는 인렛튜브;를 포함한 밀폐형 압축기가 제공된다.In addition, the casing having a closed inner space; A cylinder installed in the inner space of the casing to form a compression space and a suction hole formed to communicate with the compression space; An accumulator provided with a connection pipe so as to communicate with a compression space of the cylinder and installed outside the casing; And an inlet tube coupled to the suction hole of the cylinder and connected to the connection tube of the accumulator.
