Abstract
Description
본 발명은 로터리 타입 밀폐형 압축기에 관한 것으로, 특히 종래 밀폐형 압축기의 캡 상부에 부착된 터미널을 하단부로 옮기고 분리된 캡과 케이스를 하나로 일체화시킴으로써 생산성 향상과 제조원가를 줄인 로터리 타입 밀폐형 압축기에 관한 것이다.The present invention relates to a rotary type hermetic compressor, and more particularly, to a rotary type hermetic compressor which improves productivity and reduces manufacturing costs by moving a terminal attached to an upper portion of a cap of a conventional hermetic compressor to a lower end and integrating a separate cap and a case into one.
종래의 로터리 타입 밀폐형 압축기의 기술적 구성은 도 1에 도시된 바와 같이 케이스(1) 내주면에 압축기 펌프부의 실린더(5)와 모터(4)를 흔들림 없게 압입하고, 그 상부에 전원을 투입하는 목적으로 설치된 터미널(3)부가 부착된 캡(2)을 덮은 상태에서 모터(4)의 인출선을 터미널(3)에 접속시킨 후 "가"부를 용접하여 내부의 공간을 밀폐한다. 이때, 터미널(3)과 캡(2)은 정해진 공법에 의해 고정되는데 별도의 공정을 이용한다.The technical configuration of the conventional rotary type hermetic compressor is as shown in Figure 1 for the purpose of pressing the cylinder 5 and the motor (4) of the compressor pump portion without shaking and the power supply to the upper portion of the inner peripheral surface of the case (1). The lead wire of the motor 4 is connected to the terminal 3 in a state of covering the cap 2 with the installed terminal 3 attached thereto, and the inner space is sealed by welding the temporary portion. At this time, the terminal (3) and the cap (2) is fixed by a predetermined method using a separate process.
그런데, 이와 같이 구성된 종래의 로터리 타입 밀폐형 압축기에 있어서는, 모터(4)의 전원 투입을 위하여 모터(4)의 인출선과 캡(2)의 터미널(3)을 캡(2)을 덮은 상태에서 접속하는 제조적인 이유로 캡(2)과 케이스(1)는 반드시 분리되어 있어야 하는 문제가 있는데, 이를 위하여 캡(2)과 케이스(1)를 덮는 제조공정이 별도로 필요하게 되는 문제점이 있다.By the way, in the conventional rotary type hermetic compressor configured as described above, the lead wire of the motor 4 and the terminal 3 of the cap 2 are connected in a state in which the cap 2 is covered in order to supply power to the motor 4. There is a problem that the cap 2 and the case 1 must be separated for manufacturing reasons, and for this purpose, a manufacturing process for covering the cap 2 and the case 1 is required separately.
또한 터미널(3)과 모터(4)의 인축선을 접속한 후 내부 공간을 밀폐시키기 위하여 "가"부를 용접하는데, "가"부의 용접때 열기로 모터(4) 고정자 코일의 고정을 위해 코일 외측면에 형성시킨 "나"부의 레이싱(6)이 녹아 내릴 가능성이 아주 높기 때문에 제품의 전기적인 안전 측면에서의 신뢰성이 떨어질 우려가 있었다.In addition, after connecting the axis 3 of the motor (3) and the contraction line of the motor (4) to weld the "ga" part to seal the interior space, the outside of the coil for fixing the stator coil of the motor (4) by the heat during welding Since the racing 6 formed on the side is very likely to melt, the reliability in terms of electrical safety of the product was deteriorated.
그리고, 캡(2)이 "다"부와 같이 케이스(1)의 내부로 돌출하게 됨에 따라 "다"부와 모터(4)의 "나"부간의 사용자의 안전을 위하여 필요한 전기적인 공간거리 확보 때문에 케이스(1)의 전체적인 높이가 높아짐에 따라 재료비도 상승하게 되는 문제점이 있었다.In addition, as the cap 2 protrudes into the case 1 as in the "multi" portion, an electric space distance necessary for the safety of the user between the "multi" portion and the "b" portion of the motor 4 is secured. Therefore, as the overall height of the case 1 increases, there is a problem that the material cost also increases.
부수적으로 발생할 수 있는 문제점은 케이스(1)와 캡(2)의 일체화 용접시 용접작업 관리의 항목이 추가가 되며, 용접불량시 자재 손실의 문제점도 있었다.Incidentally, a problem that may occur incidentally is that an item of welding operation management is added when the case 1 and the cap 2 are integrally welded, and there is a problem of material loss when welding is poor.
따라서, 본 발명은 상기 문제점을 해결하기 위하여 이루어진 것으로, 본 발명의 목적은 종래 밀폐형 압축기의 캡 상부에 부착된 터미널을 하단부로 옮기고 분리된 캡과 케이스를 하나로 일체화시킴으로써 생산성 향상과 제조원가를 줄인 로터리 타입 밀폐형 압축기를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention is to move the terminal attached to the top of the cap of the conventional hermetic compressor to the lower end of the rotary type to improve productivity and reduce the manufacturing cost by integrating the separated cap and case into one It is to provide a hermetic compressor.

상기 목적을 달성하기 위하여, 본 발명의 로터리 타입 밀폐형 압축기는,In order to achieve the above object, the rotary type hermetic compressor of the present invention,
케이스 내주면에 압축기 펌프부의 실린더(10) 및 모터(9)가 압입 고정되고,The cylinder 10 and the motor 9 of the compressor pump part are press-fitted and fixed to the inner circumferential surface of the case,
상기 모터(9)의 하단부에 설치된 실린더(10)의 외곽 빈 공간에 상기 모터(9)로 전원을 공급하기 위해 터미널(8)이 형성되며,A terminal 8 is formed to supply power to the motor 9 in the outer empty space of the cylinder 10 installed at the lower end of the motor 9,
상기 압축기를 보호하기 위해 감싸고 있는 케이스(7)가 일체형으로 구비된 것을 특징으로 한다.In order to protect the compressor, it is characterized in that the case 7 is integrally provided.
이하, 본 발명의 일실시예에 관하여 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 의한 로터리 타입 밀폐형 압축기의 구조도로서, 케이스 내주면에 압입 고정된 모터(9)와, 상기 모터(9)의 하단부에 설치된 실린더(10)의 외곽 빈 공간에 상기 모터(9)로 전원을 공급하기 위해 형성된 터미널(8)과, 상기 압축기를 보호하기 위해 외곽을 감싸고 있는 케이스(7)가 일체형으로 구비된 것이 도 1에 도시된 종래의 로터리 타입 밀폐형 압축기와 다른 점이다.2 is a structural diagram of a rotary type hermetic compressor according to the present invention, in which the motor 9 is press-fitted and fixed to the inner circumferential surface of the case and the outer space of the cylinder 10 provided at the lower end of the motor 9. The terminal 8 formed to supply the furnace power and the case 7 surrounding the outer shell to protect the compressor are integrally provided, which is different from the conventional rotary type hermetic compressor shown in FIG. 1.
여기서, 본원 발명에 의해 일체화된 케이스(7)는 드로잉 공법(또는 기타 공법)을 적용하여 구현한 것으로, 종래의 캡(2)과 케이스(1)가 하나로 일체화시켰다.Here, the case 7 integrated by the present invention is implemented by applying a drawing method (or other method), and the conventional cap 2 and the case 1 are integrated into one.
그리고, 모터(4)의 전원 인출선 방향을 모터(4) 하단부의 실린더(5) 외주면에 설치된 터미널(8)로 변경하여 전원투입함으로써, 종래 레이싱(6)으로 인해 차지하던 공간을 줄였다.Then, the power take-off line direction of the motor 4 is changed to the terminal 8 provided on the outer peripheral surface of the cylinder 5 at the lower end of the motor 4 to supply power, thereby reducing the space occupied by the conventional racing 6.
이상에서 설명한 바와 같이, 본 발명에 의한 로터리 타입 밀폐형 압축기에 의하면, 압축기를 보호하기 위한 케이스를 종래 캡과 케이스로 분리되어 있던 것을 하나의 케이스로 일체화시킴으로써, 종래 밀폐형 압축기 구조에서의 캡(2)과 케이스(1)를 별도 공정을 이용하여 일체화시키는 용접공정과 용접에 따른 용접불량에 의한 냉매누설불량 및 용접되는 열로 인해 모터(4)의 레이싱(6)이 녹아내리는 문제점을 해결하였다. 그리고, 캡(2)의 모서리 부분이 모터의 레이싱(6) 부분에 닿는 것을 막기 위해 최소한의 공간 확보로 인해 압축기의 크기가 증가함으로써 발생되는 제조비용 증가문제를 해결할 수 있는 매우 뛰어난 효과가 있다.As described above, according to the rotary type hermetic compressor according to the present invention, the case for protecting the compressor is integrated into one case by separating a case for protecting the compressor into a case and a cap 2 in the conventional hermetic compressor structure. The problem that the racing 6 of the motor 4 melts due to the welding process of integrating the case 1 and the case 1 by using a separate process and the refrigerant leakage defect due to the welding failure due to the welding and the heat to be welded are solved. In addition, there is a very excellent effect to solve the manufacturing cost increase problem caused by increasing the size of the compressor due to the minimum space to prevent the edge portion of the cap (2) to contact the racing portion 6 of the motor.
