본 고안은 밀폐형 진동압축기의 압축장치에 관한 것으로 스카치요크(Scotch york)식 슬라이더를 이용하는 압축기에 있어서 슬라이더의 구조 개선으로 흡입가스의 과열방지와 성능향상을 목적으로 안출한 것이다.The present invention relates to a compression device of a hermetic vibrating compressor, and has been developed for the purpose of preventing overheating of the suction gas and improving performance in a compressor using a Scotch york slider.
종래의 스카치 요크식 슬라이더를 이용하는 전동 압축기는 편심회전운동을 크랭크에 의해 직선 왕복운동으로 전환하는 방식으로서 제 1 도에서와 같이 실린더(1)내에서 진퇴되는 피스턴(2)의 전단에 상·하 안내장공(3')을 가진 관체(3)를 T형으로 형성하고 관체(3)내에는 크랭크 샤프트(4)의 편심축(5')상단에 형성된 슬라이더(5)을 끼워 좌·우 유동 될 수 있게 한 것이며, 피스턴(2)의 왕복운동에 의해 냉매가스가 흡입사이렌서(6)를 통해 실린더(1)내로 흡입된 후 다시 토출사이렌서(7)로 토출하도록 구성되고 실린더(1)내측의 흡입공(8)과 토출공(9)에는 각각 박판형의 흡입밸브(10)와 토출밸브(11)를 설치하여 교호로 개폐되게한 것이다.Conventional electric compressors using Scotch yoke type sliders convert eccentric rotational motion into linear reciprocating motion by cranks, as shown in FIG. A tubular body 3 having a guide hole 3 'is formed in a T-shape, and in the tubular body 3, a slider 5 formed on an upper end of the eccentric shaft 5' of the crankshaft 4 can be inserted to flow left and right. And the refrigerant gas is sucked into the cylinder 1 through the suction silencer 6 by the reciprocating motion of the piston 2 and then discharged back to the discharge silencer 7 and the inside of the cylinder 1 The suction hole 8 and the discharge hole 9 of the thin plate-shaped suction valve 10 and the discharge valve 11 are respectively installed to be opened and closed alternately.
이러한 종래의 압축부 구성에서는 얇은 박판형의 밸브에 의해 흡입과 토출작동되게한 방식이므로 흡입사이렌서의 구성과 밸브가 있어야 하고 이들을 통해서 이루어지는 흡입과 토출과정의 원활한 교호개폐작동이 되지 못하여 압력손실이 많으므로 인하여 성능이 떨어지고 연속반복운동에 의한 피로응력이 걸리며 그 응력에 견딜 수 있는 밸브는 수입에 의존하므로 고가이고 가공의 정밀도가 높아야 하는 것이다.In the conventional compression section, the suction and discharge operation is performed by a thin plate-shaped valve. Therefore, the suction silencer and the configuration of the suction silencer must be provided. As a result, performance is reduced, fatigue stress caused by continuous repetitive motion, and a valve capable of withstanding the stress must be expensive and high in processing precision because it depends on imports.
본 고안은 이러한 종래 구성에서의 흡입사이렌서와 흡일밸브를 생략하는 대신에 피스턴 중심부에 외부와 연통되는 흡입공을 형성하여 흡입사이렌서와 흡입밸브에 의해서 이루어지던 흡입작용이 피스턴 자체에서 이루어지게 하므로서 흡입과 압축 작용이 원활하게 하고 흡입가스의 가열로 인한 성능저하의 요인을 없애고저한 것인바, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention forms a suction hole communicating with the outside in the center of the piston instead of omitting the suction silencer and the suction valve in the conventional configuration, so that the suction action made by the suction silencer and the suction valve is performed in the piston itself. The suction and compression action is smooth and eliminates the deterioration factor due to the heating of the suction gas, which is described in detail by the accompanying drawings as follows.
실린더(1)의 흡입공(8)는 흡입사이렌서(6)와 연결하고 토출공(9)은 토출사이렌서(7)와 연결하며 피스턴(2) 전단의 슬라이더(5)가 원주형으로 형성된 것에 있어서 흡입공(8)과 흡입사이렌서(6)를 생략하고 슬라이더(5) 중심일측에 외경이 적은 요홈부(13)를 형성하여 관체(3) 내면과의 사이에 간격(12)을 갖게하므로서 슬라이더(5)의 요홈부(13)는 관체(3) 내면에 닿지않고 타측의 원통몸체(15)만이 밀접된 상태로 슬라이드 될 수 있게하며 피스턴(2) 중앙에 관체(3)와 연통되는 미세한 흡입구멍(14)을 형성하여서 됨을 특징으로한 것이다.The suction hole 8 of the cylinder 1 is connected to the suction silencer 6, the discharge hole 9 is connected to the discharge silencer 7, and the slider 5 in front of the piston 2 is formed in a columnar shape. In this case, the suction hole 8 and the suction silencer 6 are omitted, and a recess 13 having a small outer diameter is formed on one side of the slider 5 so as to have a gap 12 between the inner surface of the tube 3. Thus, the recess 13 of the slider 5 allows only the cylindrical body 15 on the other side to slide in close contact without touching the inner surface of the tubular body 3 and communicates with the tubular body 3 at the center of the piston 2. It is characterized in that to form a fine suction hole (14).
이와 같이된 본 고안은 크랭크 사후트(4)의 편심회전운동이 피스턴(2)을 전·후 왕복운동으로 전환되어 제5(a)도, 제5(b)도, 제(c)도, 제(d)도의 순으로 작동하게 되고, 이로 인해서 실린더(1) 내에는 흡입력과 압축력 및 토출력이 발생하게 됨은 공지한 바와 같으며 본 고안에서는 흡입공(8)과 흡입사이렌서(6)를 제거하는 대신에 피스턴(2) 중심부에 흡입구멍(14)을 형성하여 피스턴(2)의 전진력에 의해 가스가 흡입구멍(14)으로 흡입되고 다시 피스턴(2)의 후진력에 의해 흡입가스가 토출공(9)으로 토출되게한 것이다.In the present invention as described above, the eccentric rotation of the crank shaft 4 is converted to the reciprocating motion of the piston 2 before and after the fifth (a), fifth (b), (c), It is known that the operation in the order of (d) degree, and this causes the suction force, the compression force and the earth output in the cylinder (1) as is known in the present invention and in the present invention the suction hole (8) and the suction silencer (6) Instead of removing, the suction hole 14 is formed in the center of the piston 2 so that the gas is sucked into the suction hole 14 by the forward force of the piston 2 and the suction gas is again caused by the backward force of the piston 2. It is to be discharged to the discharge hole (9).
즉, 제 5(d) 도의 상태에서 크랭크 샤후트(4)가 작동되면 피스턴(2)이 전진하기 시작하며 이상태에서 슬라이더(5)는 그 요홈부(13)가 흡입구멍(14)을 열어준 상태로 상승하여 제5(a)도 상태의 상한점(A)에서 다시 하강하여 제5(b)도 상태가 될 때까지는 흡입구멍(14)이 개방되며, 피스턴(2)은 상사점까지 전진하면서 흡입력을 발생시키므로 실린더(1)내에는 흡입구멍(14)으로 흡입된 가스가 차이게 된다.That is, when the crankshaft 4 is operated in the state of FIG. 5 (d), the piston 2 starts to move forward, and in this state, the slider 5 opens the suction hole 14 by the recess 13. The suction hole 14 is opened until it rises to the state and descends again from the upper limit point A of the fifth (a) degree state and reaches the fifth (b) degree state, and the piston 2 moves forward to the top dead center. While the suction force is generated, the gas sucked into the suction hole 14 in the cylinder 1 is different.
이렇게 제5(b)도 상태에서 슬라이더(5)가 계속하강하면 흡입구멍(14)이 원통몸체(15)에 의해 막히게 되고 이때부터 하한점(B)까지 하강하는 동안은 흡입구멍(14)이 원통몸체(15)에 막혀지며 피스턴(2)의 압축력이 토출공(9)쪽으로 가해지므로 제5(c) 에서 제5(d)도 상태까지는 흡입가스 피스턴(2)에 의해 완전히 토출완료 되는 것이다.Thus, if the slider 5 continues to descend in the state of FIG. 5 (b), the suction hole 14 is blocked by the cylindrical body 15, and while the suction hole 14 is lowered to the lower limit B from this time. It is blocked by the cylindrical body 15 and the compressive force of the piston 2 is applied toward the discharge hole 9, so that the discharge is completely completed by the suction gas piston 2 from the fifth (c) to the fifth (d) degree state. .
이렇게 본고안은 피스턴(2)이 전진할때는 흡입구멍(14)이 개방되는 반면에 후진할 때는 흡입구멍(14)이 막히면서 실린더(1)내의 흡입가스를 압축하여 토출되게하는 전방흡입과 후방토출방식의 직선 흡출작용에 의해 가스의 흡·출작용이 원활하고 압력손실이 없으며 토출가스의 가열로 인한 흡입가스온도가 높아질 우려가 없어 성능을 향상시킬 수 있으며 종래의 흡입축 구성인 흡입사이렌서와 흡입공 및 흡입밸브가 제거되므로 제작가를 낮출 수 있고 쉽게 제작할 수 있는 효과가 있는 것이다.In this way, the suction hole 14 is opened when the piston 2 moves forward while the suction hole 14 is blocked while the suction hole 14 is blocked, and the suction and discharge of the suction gas in the cylinder 1 are compressed and discharged. It is possible to improve the performance by the gas suction and discharge action smoothly, no pressure loss, and the suction gas temperature due to the heating of the discharge gas. Since the ball and the suction valve is removed, the manufacturing cost can be lowered and the effect can be easily manufactured.
