본 고안은 밀폐형압축기의 프레임구조에 관한 것으로서 특히 스테이터에 다량의 냉동유가 흘러들어서 발생되는 모터의 절연성을 저감시키고 냉동유의 급유량을 향상시키도록 한 것이다.The present invention relates to a frame structure of a hermetic compressor, in particular, to reduce the insulation of the motor generated by a large amount of refrigeration oil flows into the stator and to improve the refueling amount of the refrigeration oil.
일반적인 밀폐형 압축기의 구성은 제1도에서와 같이 상부셀(9)과 하부셀(8)이 외부에 결합되어 구성되었으며, 셀 내부에는 스테이터(2)와의 전기적인 상호작용에 의하여 회전하는 로터(1)와, 상기 로터(1)와 열박음 결합되어 함께 회전하는 크랭크샤프트(4)와, 상기 크랭크샤프트(4)내의 급유구(15)를 통해 급유시키도록 하단에서 냉동유(11)를 흡입하는 프로펠러(13)와, 상기 크랭크샤프트(4)의 상부에 결합되어 실린더(6)내를 왕복운동하는 피스톤(5)과, 상기 실린더(6)끝단에서 냉매가 흡토출되는 헤드커버(10)와, 상기 압축부를 지지하는 프레임(3)을 구비하였다.The general hermetic compressor is composed of an upper cell 9 and a lower cell 8 coupled to the outside as shown in FIG. 1, and a rotor 1 rotating inside the cell by electrical interaction with the stator 2. ), Which sucks the refrigeration oil 11 from the lower end so as to refuel through the oil supply port 15 in the crankshaft 4 and the crankshaft 4 which is coupled to the rotor 1 and shrink fit together and rotates together. A propeller (13), a piston (5) coupled to an upper portion of the crankshaft (4) to reciprocate in the cylinder (6), and a head cover (10) at which the refrigerant is sucked out at the end of the cylinder (6); And a frame 3 supporting the compression section.
도면중 미설명 부호 7은 프레임(3)을 지지하는 지지스프링을 나타낸다.In the figure, reference numeral 7 denotes a support spring for supporting the frame 3.
이와같이 구성된 상태에서 스테이터(2)에 전원이 인가되면 로터(1)가 회전하게 되고 동시에 크랭크샤프트(4)가 회전하게 된다.When power is applied to the stator 2 in this configuration, the rotor 1 rotates and the crankshaft 4 rotates at the same time.
여기서 스카치요크 방식으로 결합된 피스톤(5)이 실린더 내부를 왕복운동하는데 이 피스톤(5)의 왕복운동에 따라 냉매가 흡,토출부(12)를 통하여 흡입되고 압축된후 다시 토출되게 된다.Here, the piston 5 coupled in the scotch yoke method reciprocates inside the cylinder, and the refrigerant is sucked through the suction and discharge units 12 according to the reciprocating motion of the piston 5, compressed, and then discharged again.
크랭크샤프트(4)가 회전하면 크랭크샤프트의 끝단부에 있는 프로펠러(13)의 작용으로 압축기 하부셀(8)에 있는 냉동유(11)가 크랭크샤프트의 급유구(15)를 통하여 압축기 상부로 급유되어 기구부의 마찰저감 및 냉각작용을 함으로 압축기의 동작을 원활하게 한다.When the crankshaft 4 rotates, the refrigeration oil 11 in the compressor lower cell 8 is lubricated through the oil inlet 15 of the crankshaft through the action of the propeller 13 at the end of the crankshaft. Therefore, the operation of the compressor is smoothed by reducing friction and cooling of the mechanism.
이러한 압축기는 압축기하부셀(8)에 고여있는 냉동유(11)를 크랭크샤프트(4)가 회전함에 따라 상부기구부로 끌어올리는 구조로 되어 있고 상부로 올라온 냉동유는 기구부 및 상부셀(9)에 부딪혀 하부셀(8)로 다시 고이게 된다.This compressor has a structure in which the refrigeration oil 11 accumulated in the compressor lower cell 8 is pulled up to the upper mechanism part as the crankshaft 4 rotates, and the refrigeration oil raised to the upper part is attached to the mechanism part and the upper cell 9. It hits and accumulates back to the lower cell (8).
이 과정에서 대부분의 냉동유가 프레임(3)을 타고 내려와 스테이터(2)로 흘러 내려오게 되는데 이 냉동유는 스테이터(2)의 전 표면에 걸쳐 유막을 형성시킴으로서 절연성을 떨어뜨리게 되어 모터의 효율을 감소시키게 된다.In this process, most of the freezing oil flows down the frame (3) and flows down to the stator (2). This freezing oil forms an oil film over the entire surface of the stator (2), which lowers the insulation and reduces the efficiency of the motor. Let's go.
또한 프레임(3)에서 스테이터(2)를 거쳐 하부셀에 모이므로 시간지연이 발생하게 되어 결국 급유량이 줄어들고 이 급유량을 보충해 주기 위해서는 냉동유를 보다 많이 필요로 하게되어 결국 냉동유 낭비의 요인이 되는 문제점이 있었다.In addition, since the frame (3) is collected in the lower cell via the stator (2), a time delay occurs, and thus the amount of refueling is reduced, and thus, more refrigeration oil is needed to replenish the amount of refueling. There was a problem that became a factor.
본 고안은 이러한 점을 감안하여 프레임에 고인 냉동유가 하부셀로 직접 떨어지도록 프레임 일측에 냉동유경사유로를 구비함으로서, 냉동유가 스테이터로 흘러들어 모터의 절연성을 저하시키는 것을 방지하여 모터의 효율을 향상시키고 급유량의 시간지연을 저감시키도록 하는데 목적이 있다.In consideration of this, the present invention includes a freezing oil slope passage on one side of the frame so that the freezing oil accumulated in the frame falls directly into the lower cell, thereby preventing the freezing oil from flowing into the stator and reducing the insulation of the motor, thereby improving the efficiency of the motor. The purpose is to reduce the time delay of oil supply.
본 고안을 이하에서 상세히 설명한다.The present invention is described in detail below.
먼저 프레임의 구조를 살펴보면 제2(b)도에서와 같이 프레임(3)에 고인 냉동유(11)가 스테이터에 직접 닿지 않고 하부셀(8)로 직접 떨어지도록 프레임(3) 일측에 냉동유경사유로(20)를 구비하고, 상기 냉동유경사유로(20)은 냉동유가 고일수 있도록 끝단에 단턱(21)을 구성하였다.Looking at the structure of the frame first, as shown in FIG. 2 (b), the refrigeration oil 11 accumulated on the frame 3 falls directly on the lower side of the frame 3 without directly contacting the stator. Furnace 20 is provided, the freezing oil slope passage 20 has a stepped portion 21 at the end so that the frozen oil can be stored.
본 고안의 작동은 먼저 크랭크샤프트(4)의 회전에 의하여 비산되는 냉동유(11) 가운데 프레임(3)에 고인 다량의 냉동유(11)가 가장자리에 일정한 각도를 가지고 설치된 경사유로(20)를 따라 하부셀(8)로 흘러 내릴 수 있도록 하여 직접적으로 스테이터(2)에 냉동유(11)가 접촉됨으로 형성되는 유막현상을 방지하도록 하고 냉동유(11)의 비산과 동시에 빠른시간내에 회수되도록 하였다.The operation of the present invention is the first inclined flow path 20 is installed at a constant angle on the edge of the refrigeration oil 11 is scattered by the rotation of the crankshaft (4) a large amount of freezing oil (11) on the edge Accordingly, it is possible to flow down to the lower cell 8 to prevent the oil film formed by contacting the refrigeration oil 11 directly to the stator 2 and to be recovered within a short time at the same time as the refrigeration oil 11 is scattered. .
이상에서 살펴본 바와같은 본 고안은 프레임에 고인 냉동유가 스테이터로 흘러들어 모터의 절연성을 저하시키는 것을 방지하여 모터이 효율을 향상시키고 급유량의 시간지연을 저감시키도록 한 고안이다.The present invention as described above is to prevent the refrigeration oil accumulated in the frame flow into the stator to reduce the insulation of the motor to improve the efficiency of the motor and to reduce the time delay of the oil supply.
