본 발명은 냉장고용 압축기의 내부 구성본체를 지지하기 위한 일체화된 지지구에 관한 것으로, 특히 하우징속에 장착된 기구부와 구동부들로 이루어지는 구성 본체를 하나로 일체화된 지지구로 지지하도록 개선된 구조의 압축기 구성 본체 지지구에 관한 것이다.The present invention relates to an integrated support for supporting an internal component of a compressor for a refrigerator, and in particular, a compressor configured main body having an improved structure to support a component main body including a mechanism part and a driving part mounted in a housing as an integrated support part. It is about a support.

일반적으로, 냉장고에서 냉매 가스를 압축하기 위한 압축기는 도 1에 개략적으로 도시된 바와같이 밀폐되는 하우징(1)속에 고정자(2)를 포함한 프레임(3)이 스프링으로 진동이 흡수되게 지지되어 있으며, 고정자의 중심부 위치의 프레임에 형성된 홀에 회전자(4)가 구비된 샤프트(5)가 회전가능하게 장착되어 있고, 샤프트의 상단은 편심되어 냉매를 흡입 및 압축하기 위하여 제공된 실린더(6)의 피스톤(7)을 구동하도록 구성되어 있다. In general, the compressor for compressing the refrigerant gas in the refrigerator is a frame (3) including the stator (2) in the sealed housing (1) as schematically shown in Figure 1 is supported so that the vibration is absorbed by the spring, A shaft 5 with a rotor 4 is rotatably mounted in a hole formed in a frame at the center position of the stator, and an upper end of the shaft is eccentric to provide a piston of the cylinder 6 provided for sucking and compressing the refrigerant. (7) is configured to be driven.

이러한 구조의 냉장고 압축기에서 고정자에 전류가 인가되면 고정자와 회전자 사이의 전자기적 작용에 의해 회전자와 함께 샤프트가 회전하게 되며, 이와같이 샤프트의 회전에 의해 샤프트에 연결된 피스톤(7)이 왕복운동하여 실린더(6)에서 냉매를 압축 및 토출하게 된다. 이를 위하여 상기 실린더(6)에는 압축된 냉매의 토출을 위하여 판상의 토출밸브(10)가 제공된다.In a refrigerator compressor having such a structure, when a current is applied to the stator, the shaft rotates together with the rotor by the electromagnetic action between the stator and the rotor. As such, the piston 7 connected to the shaft reciprocates by the rotation of the shaft. The refrigerant is compressed and discharged from the cylinder 6. To this end, the cylinder 6 is provided with a plate-shaped discharge valve 10 for discharging the compressed refrigerant.

상기 압축기의 하우징 하부에는 회전하는 샤프트의 원활한 회전을 위하여 그리고 냉각작용을 위하여 오일이 저장되고, 샤프트에는 내부에 유로(8)가 형성되어 있으며 샤프트의 하단부에는 오일을 샤프트의 상단부로 공급하도록 오일 펌프(9)가 내장되어 있다.The oil is stored in the lower part of the housing of the compressor for smooth rotation of the rotating shaft and for cooling, the oil passage is formed in the shaft, and the oil pump is provided at the lower end of the shaft to supply oil to the upper end of the shaft. (9) is built in.

상기와 같은 압축기 내부의 구성 요소들은 전체적으로 프레임에 의해 일체화되어 통상적으로 도 2 내지 도 5에 도시된 바와같이 하우징의 저면에 미리 설정된 4곳에 스프링 지지구(11)가 용접에 의해 고정되어 구성 본체를 지지하며 중앙부에는 하부 스토퍼(12)가 배치되어 샤프트의 하단부를 회전가능하게 지지하도록 되어 있다. 도 2와 도 3 그리고 도 4와 도 5는 다른 형태의 하부 스토퍼를 보여주지만 공통적으로 정확한 위치선정 및 용접의 어려움이 존재한다.The components inside the compressor as a whole are integrated by a frame, and as shown in FIGS. 2 to 5, the spring supports 11 are fixed by welding at four preset positions on the bottom of the housing to form a component main body. The lower stopper 12 is disposed at the center and rotatably supports the lower end of the shaft. 2 and 3 and 4 and 5 show different types of lower stoppers, but there are common difficulties in accurate positioning and welding.

이와같은 종래 압축기의 구성 본체의 지지구조에서는 4개의 독립된 지지구와 하나의 스토퍼를 정확한 위치에 용접해야 하므로 정위치 용접에 어려움이 있었다.In the conventional support structure of the constituent body of the compressor, four independent supports and one stopper have to be welded in the correct position, which causes difficulty in welding in place.

따라서, 본 발명은 상술한 종래 압축기의 구성 본체의 지지구조에 따른 문제점을 해소하도록 스토퍼를 포함한 5개의 지지요소들을 하나로 일체화하여 한번의 용접으로 5곳의 지지요소들을 배치할 수 있도록 개선된 압축기 구성 본체의 지지용의 일체화된 지지구의 제공을 목적으로 한다.Accordingly, the present invention is an improved compressor configuration to integrate the five support elements including the stopper into one in order to solve the problems caused by the support structure of the main body of the conventional compressor described above to arrange the five support elements in one welding. An object of the present invention is to provide an integrated support for supporting the main body.

상기한 목적을 달성하기 위한 냉장고 압축기의 구성본체 지지용의 일체화된 지지구는 하우징 저면에 복수개의 스프링 지지구와 중앙의 샤프트 지지용의 스토퍼가 제공되는 압축기용 구성 본체 지지구로서, 상기 지지구들과 스토퍼는 하나의 장방형 판상의 부재를 프레스가공에 의해 소정의 이격된 위치에 하부의 스프링 지지 용 돌출부들을 형성하고, 중앙부에는 홀이 형성된 샤프트 하단부 지지용의 스토퍼부를 성형하여 일체화되게 구성된다.The integrated support for supporting the main body of the refrigerator compressor for achieving the above object is a component main body support for the compressor provided with a plurality of spring support on the bottom of the housing and a stopper for supporting the shaft in the center, the support and the stopper The single rectangular plate-like member is formed by forming a lower spring support protrusions at predetermined spaced apart positions by pressing, and forming a stopper portion for supporting a shaft lower end portion having a hole formed at the center thereof to be integrated.

이하, 본 발명의 실시예를 도시한 첨부 도면을 참고하여 본 발명을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

도 6 내지 도 8은 본 발명에 따라 압축기 구성 본체를 스프링으로 지지하도록 4개의 지지구들과 샤프트의 하단부를 회전가능하게 지지하기 위한 하부 스토퍼를 하나의 판상의 부재(20)를 성형하여 구성한 것을 보여준다.6 to 8 show that the four stoppers and the lower stopper for rotatably supporting the lower end of the shaft are formed by molding one plate-like member 20 to support the compressor configuration main body with a spring according to the present invention. .

즉, 하나의 장방형 판상의 부재를 소정의 이격된 위치에 종래의 지지구와 동일한 형상의 스프링 지지용 돌출부(22)들을 형성하고, 중앙부에는 종래 중앙의 스토퍼와 같이 홀이 형성된 샤프트 지지용 스토퍼(23)를 성형하여 일체화된 지지구를 구성한다(도 7참조). That is, one rectangular plate-like member is formed at a predetermined distance from the spring support protrusions 22 having the same shape as the conventional support, and the shaft support stopper 23 having a hole formed in the center portion, such as a conventional stopper. ) To form an integrated support (see FIG. 7).

상기 일체화된 지지구는 하우징의 저면에 용접하게 되는데 용접을 용이하게 하기 위하여 스프링 지지용 돌출부(22)의 측부에 용접 돌기(25)을 형성하여 스폿 용접을 하도록 한다.The integrated support is welded to the bottom of the housing to form a welding projection 25 on the side of the spring support projection 22 to facilitate the welding spot welding.

또한, 판상의 일체화된 지지구에 의해 하우징 하부에 수용되는 오일의 흐름이 방해되지 않도록 본 발명의 지지구에는 도 6에 도시한 바와같이 복수개의 홀(24)들을 형성하는 것이 바람직하다.In addition, it is preferable to form a plurality of holes 24 in the support of the present invention as shown in FIG. 6 so that the flow of oil contained in the lower portion of the housing is not hindered by the plate-like integrated support.

또한, 변형예로서 4개의 스프링 지지구를 돌출되게 형성하는 대신 그 위치에 기준 홀을 형성하고 종래의 지지구를 압접에 의해 고정하는 것도 가능하다. In addition, as a modification, instead of forming four spring supports to protrude, it is also possible to form a reference hole at the position and fix the conventional supports by pressure welding.

본 발명에 따라, 하나의 판상에 4개의 스프링 지지구와 중앙에 하나의 샤프트 지지용 돌출부를 프레스 성형에 의해 형성하므로 서로의 상대적 위치를 정확히 제어할 수 있으며, 용접하는 부품 수가 종래 5개에서 하나로 감소되므로 용접 불량이 크게 감소되는 장점이 있다. According to the present invention, four spring supports on one plate and one shaft support protrusion at the center are formed by press molding, so that the relative positions of each other can be precisely controlled, and the number of parts to be welded is reduced from one to five conventionally. Therefore, there is an advantage that the welding failure is greatly reduced.
