In this state, an electric current is applied to the suction pipe 21, the discharge pipe 22, and the refrigerant injection pipe 23, and each of the welding protrusions 21b, 22b, 23b is melted by resistance heat and the lower container. (5) to be welded to the through holes (5), (5b) and (5c), respectively.

다음, 상기 하부용기(5)에 구동모터(2)와 압축기 본체(3)를 결합한 후 상기 흡입관(21)에 연결부재를 결합하거나 또는 상기 토출관(22)에 루프파이프를 결합하고, 상기 하부용기(5)에 상부용기(6)를 복개한 후 그 하부용기(5)와 상부용기(6)의 이음부를 용접하여 결합한다.Next, the drive motor 2 and the compressor main body 3 are coupled to the lower container 5, and then a coupling member is coupled to the suction pipe 21, or a loop pipe is coupled to the discharge pipe 22. After the upper container 6 is covered in the container 5, the lower container 5 and the joints of the upper container 6 are welded to each other.

이렇게 하여, 상기 흡입관이나 토출관 그리고 냉매주입관을 조립할 때 별도의 용접관을 사용하지 않고도 용이하게 조립할 수 있고 저렴한 강관을 사용할 수 있어 생산비용을 크게 절감할 수 있을 뿐만 아니라, 상기 흡입관이나 토출관 그리고 냉매주입관을 강 재질로 형성함에 따라 각 관의 강도가 증가되어 파손을 미연에 방지할 수 있다.In this way, when assembling the suction pipe, the discharge pipe and the refrigerant injection pipe, it is possible to easily assemble without using a separate welding pipe, and to use an inexpensive steel pipe, which not only greatly reduces the production cost, but also the suction pipe or the discharge pipe. And as the refrigerant inlet pipe is formed of a steel material, the strength of each pipe can be increased to prevent damage in advance.
