일반적으로 밀폐형 압축기는 전기 모터나 터빈과 같은 동력 발생 장치로부터 동력을 전달받아 공기나 냉매 또는 그 밖의 다양한 작동 유체를 피스톤의 왕복 운동으로 압축시켜서 작동 유체의 압력을 높여주는 장치로써, 냉장고와 에어컨 등과 같은 가전 기기 또는 산업 전반에 걸쳐 널리 사용되고 있다. In general, a hermetic compressor is a device that receives power from a power generating device such as an electric motor or a turbine and compresses air, refrigerant, or various other working fluids through a reciprocating motion of a piston to increase the pressure of the working fluid, such as refrigerators, air conditioners, etc. It is widely used throughout the same home appliance or industry.
냉동 시스템에 탑재되는 밀폐형 압축기 역시 고 효율화를 구현하기 위하여 상용 전원 주파수 미만의 낮은 운전 주파수대부터 상용 전원 주파수 이상의 높은 운전 주파수대까지 넓은 주파수 대역에서 운전 가능한 밀폐형 압축기가 적용되고 있는 추세이다. Hermetic compressors installed in refrigeration systems also tend to be operated in a wide frequency band from a low operating frequency band below the commercial power frequency to a high operating frequency band higher than the commercial power frequency in order to realize high efficiency.
종래 밀폐형 압축기는 밀폐 용기 내 실린더 블록에 고정된 스테이터가 네 개의 코일 스프링에 의해 탄성 지지된다. 이때, 코일 스프링의 상단은 스테이터 하면의 고정 부재에 연결되고, 코일 스프링의 하단은 밀폐 용기의 바닥면에 고정된다. In the conventional hermetic compressor, the stator fixed to the cylinder block in the hermetic container is elastically supported by four coil springs. At this time, the upper end of the coil spring is connected to the fixing member of the lower surface of the stator, and the lower end of the coil spring is fixed to the bottom surface of the sealed container.
그런데, 밀폐형 압축기에 낙하, 운반, 또는 진동이 발생되는 경우, 밀폐 용기의 내부에 설치된 구동부(일 예로, 실린더 블록) 또는 압축 유닛(일 예로, 압축실)등이 코일 스프링 탄성 지지대로부터 이탈될 수 있으며, 밀폐 용기의 내벽에 접촉하여 마찰 소음이 크게 발생될 수 있고, 이로 인해 부품들의 파손이 야기될 수 있다.However, when the hermetic compressor is dropped, transported, or vibrated, the driving unit (eg, cylinder block) or compression unit (eg, compression chamber) installed inside the sealed container may be separated from the coil spring elastic support. In addition, friction noise may be generated greatly in contact with the inner wall of the sealed container, which may cause damage to parts.

상기 리어 댐퍼 조립체는 상기 실린더 블록에 삽입되는 결합부를 더 포함할 수 있다.The rear damper assembly may further include a coupling part inserted into the cylinder block.
상기 제1 완충부와 상기 상부 셀은 제1 유격 거리를 형성하고, 상기 제1 유격 거리는 상기 제1 완충부와 상기 상부 셀 사이에서의 수직 방향으로 이격된 최소 거리로 정의될 수 있다.The first buffer unit and the upper cell may form a first clearance distance, and the first clearance distance may be defined as a minimum distance spaced apart in a vertical direction between the first buffer unit and the upper cell.
상기 제2 완충부와 상기 상부 셀은 제2 유격 거리를 형성하고, 상기 제2 유격 거리는 상기 제2 완충부와 상기 상부 셀 사이에서의 수평 방향으로 이격된 최소 거리로 정의될 수 있다.The second buffer unit and the upper cell may form a second clearance distance, and the second clearance distance may be defined as a minimum distance spaced apart in a horizontal direction between the second buffer unit and the upper cell.
상기 리어 댐퍼 조립체는, 상기 결합부, 상기 몸체 및 상기 제1 완충부에 삽입되는 보강부재를 더 포함할 수 있다.The rear damper assembly may further include a reinforcing member inserted into the coupling part, the body, and the first buffer part.
상기 고정 부재는 상기 결합부와 동일선상에 위치하도록 상기 스테이터를 관통하고, 적어도 일부가 상기 실린더 블록에 삽입될 수 있다.The fixing member may pass through the stator so as to be positioned on the same line as the coupling part, and at least a part thereof may be inserted into the cylinder block.
상기 제2 완충부는 상기 실린더 블록의 측면 형상을 따라 곡률지게 형성될 수 있다.The second buffer may be formed to be curved along the side shape of the cylinder block.
밀폐 용기의 상부 셀과 실린더 블록에 리어 댐퍼 조립체를 설치하여, 셀과 압축 유닛 및 구동부 간의 거리를 감소시킴으로써 코일 스프링 지지대에서 압축 유닛 또는 구동부의 이탈과 파손을 방지할 수 있고, 셀과 실린더 블록 간 충격으로 인한 소음을 방지할 수 있다는 이점이 있다.By installing a rear damper assembly in the upper shell and cylinder block of the sealed container, it is possible to reduce the distance between the cell and the compression unit and the driving part, thereby preventing separation and damage of the compression unit or the driving part from the coil spring support, and between the cell and the cylinder block.

As an example, the fixing member 400 may be configured as a stator bolt. The stator bolt includes a head portion 410 and a screw portion 420 extending from the head portion 410 to pass through the stator 310 and inserted into one side of the insertion hole 222 of the cylinder block 220 to be screwed together. may include
예컨대, 스테이터 볼트는 스테이터(310) 및 실린더 블록(220)에 삽입한 상태에서, 이들 스테이터(310) 및 실린더 블록(220)을 상호 고정할 수 있다. 이때, 스테이터 볼트의 헤드부(410)는 스테이터(310)의 하면에 노출되어 탄성 부재(500)에 의해 탄성 지지될 수 있다.For example, in a state in which the stator bolts are inserted into the stator 310 and the cylinder block 220 , the stator 310 and the cylinder block 220 may be mutually fixed. In this case, the head portion 410 of the stator bolt may be exposed to the lower surface of the stator 310 to be elastically supported by the elastic member 500 .
탄성 부재(500)는 구동부(300)를 지지하도록 고정 부재(400)의 하단(스테이터 볼트의 헤드부)과 하부 셀(110)의 소켓 사이에 설치될 수 있다.The elastic member 500 may be installed between the lower end of the fixing member 400 (the head of the stator bolt) and the socket of the lower cell 110 to support the driving unit 300 .
탄성 부재(500)는 밀폐 용기(100)의 내부에서 구동부(300)를 탄성 지지함으로써, 구동부(300)에서 발생하는 진동을 흡수하여 감쇄시킬 수 있다. 예컨대, 탄성 부재(500)의 하단부는 밀폐 용기(100)의 저면에 마련된 소켓에 삽입될 수 있다. 그리고 탄성 부재(500)의 상단부는 고정 부재(400)를 탄성 지지할 수 있다. 이러한 탄성 부재(500)는 코일 스프링을 포함할 수 있다.The elastic member 500 may absorb and attenuate vibrations generated in the driving unit 300 by elastically supporting the driving unit 300 inside the sealed container 100 .

리어 댐퍼 조립체(600)는 상부 셀(120) 간에 유격 거리가 제한되도록 실린더 블록(220)에 결합될 수 있다. 보다 자세하게, 리어 댐퍼 조립체(600)는 실린더 블록(220)의 모서리부분에 위치할 수 있다.The rear damper assembly 600 may be coupled to the cylinder block 220 such that the clearance distance between the upper cells 120 is limited. In more detail, the rear damper assembly 600 may be located at a corner of the cylinder block 220 .
리어 댐퍼 조립체(600)는 사출 성형되는 플라스틱 소재일 수 있다. 이에 따라, 밀폐형 압축기(10)의 낙하, 운반, 또는 진동 등으로 인해, 실린더 블록(220)과 상부 셀(120) 간 접촉을 방지하여, 실린더 블록(220)과 상부 셀(120) 간 충격 및 소음을 감소시킬 수 있으며, 상부 셀과 실린더 블록 간의 충격에 의한 칩 이물 발생을 미연에 방지 할 수 있다.The rear damper assembly 600 may be made of an injection-molded plastic material.

도 3 내지 도 5를 참고하면, 리어 댐퍼 조립체(600)는 몸체(610), 제1 완충부(620), 제2 완충부(630), 결합부(640), 및 보강부재(660)를 포함할 수 있다.3 to 5 , the rear damper assembly 600 includes a body 610 , a first buffer 620 , a second buffer 630 , a coupling part 640 , and a reinforcing member 660 . may include
몸체(610)는 실린더 블록의 상면에 위치되어 제1 완충부(620) 및 제2 완충부(630)를 지지할 수 있다. 또한, 몸체(610)는 플라스틱 재질로 형성될 수 있다.The body 610 may be positioned on the upper surface of the cylinder block to support the first buffer 620 and the second buffer 630 . In addition, the body 610 may be formed of a plastic material.
제1 완충부(620)는 몸체(610)의 상면에서 상측 방향으로 연장되도록 배치될 수 있다. 제1 완충부(620)는 실린더 블록(220)의 상면이 상부 셀(120)과 직접 접촉되는 것을 방지하는 역할을 한다. 제1 완충부(620)와 상부 셀(120)은 제1 유격 거리(L1)로 서로 이격될 수 있다. 제1 유격 거리(L1)는 제1 완충부(620)와 상부 셀(120) 사이에서 수직 방향으로 이격된 최소 거리로 정의된다. 여기서, 제1 유격 거리(L1)은, 예를 들어, 2mm 이하로 형성될 수 있다. 이처럼 제1 완충부(620)를 배치함에 따라 제1 유격 거리(L1)를 형성함으로써 상측 방향으로 압축 유닛(200) 및 구동부(300)가 이탈되거나 파손되는 것을 방지할 수 있다. 또한, 제1 완충부(620)의 수평방향 단면적은 상측 방향으로 갈수록 작게 형성될 수 있으며, 제1 완충부(620)는 플라스틱 재질로 형성될 수 있다.The first buffer 620 may be disposed to extend upwardly from the upper surface of the body 610 . The first buffer 620 serves to prevent the upper surface of the cylinder block 220 from being in direct contact with the upper cell 120 . The first buffer unit 620 and the upper cell 120 may be spaced apart from each other by a first clearance distance L1. The first clearance distance L1 is defined as a minimum distance vertically spaced apart between the first buffer unit 620 and the upper cell 120 . Here, the first clearance distance L1 may be, for example, 2 mm or less. As such, by disposing the first buffer unit 620 , the first clearance distance L1 is formed, thereby preventing the compression unit 200 and the driving unit 300 from being separated or damaged in the upward direction. In addition, the horizontal cross-sectional area of the first buffer unit 620 may be formed to be smaller toward the upper direction, and the first buffer unit 620 may be formed of a plastic material.
제2 완충부(630)는 몸체(610)의 외면에서 실린더 블록(220)의 측면을 따라 하측 방향으로 연장 형성되어, 실린더 블록(220)의 측면이 상부 셀(120)에 접촉되는 것을 방지하는 역할을 한다. 이에 따라, 제2 완충부(630)와 상부 셀(120)은 제2 유격 거리(L2)을 형성할 수 있으며, 제2 유격 거리(L2)는 제2 완충부(630)와 상부 셀(120) 사이에서의 수평 방향으로의 이격된 최소 거리로 정의될 수 있다. 제2 유격 간격(L2)은, 예를 들어, 2mm 이하로 형성될 수 있다. 이처럼 제2 완충부(630)를 배치함에 따라 제2 유격 거리(L2)가 형성함으로써 수평 방향으로 압축 유닛(200) 및 구동부(300)가 이탈되거나 파손되는 것을 방지할 수 있다.The second buffer 630 is formed extending downward along the side surface of the cylinder block 220 from the outer surface of the body 610, preventing the side surface of the cylinder block 220 from contacting the upper cell 120 plays a role Accordingly, the second buffer unit 630 and the upper cell 120 may form a second clearance distance L2, and the second clearance distance L2 is the second buffer unit 630 and the upper cell 120. ) can be defined as the minimum distance apart in the horizontal direction between The second clearance gap L2 may be, for example, 2 mm or less. As such, by disposing the second buffer unit 630, the second clearance distance L2 is formed, thereby preventing the compression unit 200 and the driving unit 300 from being separated or damaged in the horizontal direction.
또한, 제2 완충부(630)는 실린더 블록(220)의 측면에서 이격되도록 형성될 수 있다. 제2 완충부(630)는 그 내측면이 실린더 블록(220)과 서로 이격되도록 배치될 수 있다. 예컨대, 제2 완충부(630)의 내측면과 대향하는 실린더 블록(220)의 측면을 대향면이라 할 때, 실린더 블록(220)의 대향면과 삽입홀(222)의 중심간의 거리는, 제2 완충부(630)의 내측면과 보강부재(650)의 중심간의 거리보다 더 작을 수 있다. 제2 완충부(630)를 실린더 블록(220)으로부터 이격되도록 형성하는 이유는 제2 완충부(630) 및 실린더 블록(220) 중 적어도 하나가 사출 성형됨에 따라 표면이 고르지 않게 형성될 수 있기 때문에다. 이와 같이 이격되도록 형성되어 있지 않다면, 제2 완충부(630)의 내측면과 실린더 블록(220)의 대향면이 접촉되어 리어 댐퍼 조립체(600)가 실린더 블록(220)에 결합되지 않을 수 있으므로, 제2 완충부(630)를 실린더 블록(220)으로부터 이격되도록 형성함에 따라 리어 댐퍼 조립체(600)는 효율적으로 실린더 블록(220)에 결합될 수 있다.In addition, the second buffer 630 may be formed to be spaced apart from the side of the cylinder block 220 . The second buffer 630 may be disposed so that its inner surface is spaced apart from the cylinder block 220 from each other. For example, when the side surface of the cylinder block 220 opposite to the inner surface of the second buffer 630 is referred to as the opposite surface, the distance between the opposite surface of the cylinder block 220 and the center of the insertion hole 222 is the second It may be smaller than the distance between the inner surface of the buffer part 630 and the center of the reinforcing member 650 . The reason why the second buffer 630 is formed to be spaced apart from the cylinder block 220 is that the surface may be unevenly formed as at least one of the second buffer 630 and the cylinder block 220 is injection molded. all. If it is not formed to be spaced apart as described above, the rear damper assembly 600 may not be coupled to the cylinder block 220 because the inner surface of the second buffer 630 and the opposite surface of the cylinder block 220 come into contact with each other, As the second buffer 630 is formed to be spaced apart from the cylinder block 220 , the rear damper assembly 600 may be efficiently coupled to the cylinder block 220 .
또한, 제2 완충부(630)는 실린더 블록(220)의 측면 형상을 따라 곡률지게 형성될 수 있으며, 플라스틱 재질로 형성될 수 있다.In addition, the second buffer 630 may be formed to be curved along the side shape of the cylinder block 220, it may be formed of a plastic material.
한편, 제1 유격 거리(L1)와 제2 유격 거리(L2)는, 고정 부재(400)가 탄성 부재(500)에 의해 탄성 지지될 때, 고정 부재(400)가 상하 이동 가능한 탄성 지지 거리(L3)보다 짧은 거리를 유지할 수 있다. On the other hand, the first clearance distance L1 and the second clearance distance L2 are the elastic support distances at which the fixing member 400 can vertically move when the fixing member 400 is elastically supported by the elastic member 500 ( L3) can be maintained at a shorter distance.
이와 같이, 제1 유격 거리(L1)와 제2 유격 거리(L2)가 탄성 지지 거리(L3)보다 짧은 거리를 유지하면, 밀폐형 압축기(10)의 낙하, 운반, 또는 진동 등이 발생되더라도, 탄성 부재(500)에 의해 탄성 지지되는 구동부(스테이터, 실린더 블록 등)가 탄성 부재(500)에서 이탈되는 현상을 미연에 방지할 수 있다. As such, when the first clearance distance L1 and the second clearance distance L2 are kept shorter than the elastic support distance L3, even if the hermetic compressor 10 falls, transports, or vibrates, the elasticity A phenomenon in which the driving part (stator, cylinder block, etc.) elastically supported by the member 500 is separated from the elastic member 500 may be prevented in advance.
결합부(640)는 실린더 블록(220)의 삽입홀(222)의 타측에 삽입되도록 형성되어 리어 댐퍼 조립체(600)를 실린더 블록(220)에 결합시키는 역할을 한다. 또한, 결합부(640)는 몸체(610)의 하면에서에서 하측 방향으로 형성되어 삽입홀(222)에 삽입될 수 있다. 이러한 결합부(630)와 고정 부재(400)는 동일선상에 위치될 수 있다. The coupling part 640 is formed to be inserted into the other side of the insertion hole 222 of the cylinder block 220 , and serves to couple the rear damper assembly 600 to the cylinder block 220 . In addition, the coupling portion 640 may be formed in a downward direction from the lower surface of the body 610 to be inserted into the insertion hole (222). The coupling part 630 and the fixing member 400 may be positioned on the same line.
결합부(640)는 몸체(610), 제1 완충부(620)와 제2 완충부(630)와 동일하게 플라스틱 재질로 형성될 수 있다.The coupling part 640 may be formed of a plastic material in the same way as the body 610 , the first buffer part 620 , and the second buffer part 630 .
보강부재(650)는 결합부(630), 몸체(610), 및 제1 완충부(620)에 삽입되도록 형성되어 리어 댐퍼 조립체(600)의 강성 보강 역할을 한다. 몸체(610), 제1 완충부(620), 제2 완충부(630), 결합부(640)는 플라스틱 재질로 충격에 약하다. 이를 보강하기 위하여 보강부재(650)는 몸체(610), 제1 완충부(620), 제2 완충부(630), 결합부(640)보다 고강성 재질로 형성될 수 있다. 예컨대, 보강부재(650)는 철과 같은 금속으로 형성될 수 있다.The reinforcing member 650 is formed to be inserted into the coupling part 630 , the body 610 , and the first buffer part 620 , and serves to reinforce the rigidity of the rear damper assembly 600 . The body 610, the first buffering part 620, the second buffering part 630, and the coupling part 640 are made of a plastic material and are weak against impact. In order to reinforce this, the reinforcing member 650 may be formed of a material having a higher rigidity than the body 610 , the first buffering part 620 , the second buffering part 630 , and the coupling part 640 . For example, the reinforcing member 650 may be formed of a metal such as iron.
한편, 몸체(610), 제1 완충부(620), 제2 완충부(630), 결합부(640) 및 보강부재(650)는 인서트 사출을 통하여 형성될 수 있다.Meanwhile, the body 610 , the first buffering part 620 , the second buffering part 630 , the coupling part 640 and the reinforcing member 650 may be formed through insert injection.
다시 도 2 및 도 3을 참고해보면, 헤드 댐퍼(700)는 상부 셀(120) 간에 유격 거리가 제한되도록 압축실(210)의 상부에 장착될 수 있다. 헤드 댐퍼(700)는 압축실(210)의 상부를 덮는 완충 재질로 이루어질 수 있다. 이에 따라, 밀폐형 압축기(10)의 낙하, 운반, 또는 진동 등으로 인해, 압축실(210)과 상부 셀(120) 간 접촉이 발생되는 경우, 헤드 댐퍼(700)는 압축실(210)과 상부 셀(120) 간 충격 및 소음 발생을 감소시킬 수 있다.Referring back to FIGS. 2 and 3 , the head damper 700 may be mounted on the upper portion of the compression chamber 210 so that the clearance distance between the upper cells 120 is limited. The head damper 700 may be made of a cushioning material that covers the upper portion of the compression chamber 210 . Accordingly, when a contact between the compression chamber 210 and the upper cell 120 occurs due to the drop, transport, or vibration of the hermetic compressor 10 , the head damper 700 is connected to the compression chamber 210 and the upper part. It is possible to reduce the generation of impact and noise between the cells 120 .
루프파이프(800)는 압축실(210)에 냉매를 유동시킬 수 있다. 예컨대, 루프파이프(800)는 냉매 압축을 위한 냉매를 압축 유닛(200)으로 안내하고 압축 유닛(200)으로부터 압축된 냉매를 흡토출유닛(미도시)으로 안내할 수 있다. The loop pipe 800 may flow a refrigerant into the compression chamber 210 . For example, the loop pipe 800 may guide the refrigerant for refrigerant compression to the compression unit 200 and guide the refrigerant compressed from the compression unit 200 to an intake/discharge unit (not shown).
이러한 루프파이프(800)는 상부 셀(120) 간에 유격 거리가 제한되도록 밀폐 공간 내에서 굴곡 연장될 수 있다. 이때, 루프파이프(800)의 적어도 일부에는, 루프파이프(800)의 둘레면을 덮는 파이프 댐퍼(900)가 마련될 수 있다.The loop pipe 800 may be bent and extended in the enclosed space so that the clearance distance between the upper cells 120 is limited. In this case, at least a portion of the roof pipe 800 may be provided with a pipe damper 900 covering the circumferential surface of the roof pipe 800 .
파이프 댐퍼(900)는 루프파이프(800)의 둘레면을 덮는 완충 재질로 구성되며, 밀폐형 압축기(10) 구동 시 구동부(300)로부터 발생되는 실린더 블록 또는 루프 파이프의 진동 소음을 감소 시킬 수 있다.The pipe damper 900 is made of a cushioning material covering the circumferential surface of the loop pipe 800 , and can reduce vibration noise of a cylinder block or a roof pipe generated from the driving unit 300 when the hermetic compressor 10 is driven.
이에 따라, 실린더 블록(220)의 네 개 모서리부 중에서, 압축실(210)이 위치한 실린더 블록(220)의 양 쪽 모서리는 헤드 댐퍼(700)에 의해 안정적으로 지지될 수 있고, 압축실(210)이 위치하지 아니한 실린더 블록(220)의 상면 양 쪽 모서리는, 리어 댐퍼 조립체(600)에 의해 안정적으로 지지될 수 있다. Accordingly, among the four corners of the cylinder block 220 , both corners of the cylinder block 220 where the compression chamber 210 is located may be stably supported by the head damper 700 , and the compression chamber 210 may be stably supported by the head damper 700 . ) may be stably supported by the rear damper assembly 600 at both corners of the upper surface of the cylinder block 220 .
물론, 본 실시예에서, 리어 댐퍼 조립체(600)는 헤드 댐퍼(700)가 설치되지 아니한 실린더 블록(220)의 모서리에 설치되지만, 이에 한정되지는 아니하며, 리어 댐퍼 조립체(600)는 실린더 블록(220)의 모서리 중 적어도 어느 하나 이상에 추가적으로 설치될 수 있을 것이다. Of course, in this embodiment, the rear damper assembly 600 is installed at the corner of the cylinder block 220 where the head damper 700 is not installed, but is not limited thereto, and the rear damper assembly 600 is a cylinder block ( 220) may be additionally installed on at least any one or more of the corners.
