일반적인 밀폐형 전동압축기는 제1도에서와 같이 하부쉘과 상부쉘이 복개 고정되어 형성된 밀폐용기(9)와, 상기 밀폐용기(9)의 내부 중간부에 설치된 프레임(10)과, 상기 프레임(10)의 중심 하부에는 전동기구부가 구성되고 하부에는 압축기구부가 구성되었다.A typical hermetic electric compressor is a hermetically sealed container (9) formed by fixing the lower shell and the upper shell as shown in FIG. 1, a frame (10) installed at an inner middle portion of the hermetic container (9), and the frame (10) In the lower part of the center, the electric mechanism part is configured and the compression mechanism part is configured in the lower part.
그리고 상기 전동기구부는 프레임(10)의 중간부에 회전가능하도록 지지되는 크랭크샤프트(2)와, 상기 크랭크샤프트(2)에 고정된 회전자(1)와, 상기 회전자(1)와 적정간극을 유지하며 프레임(10) 하부에 고정된 고정자(4)로 구성되었으며 상기 크랭크샤프트(2)는 밀폐용기(9)하부의 냉동기유(13)를 흡상하여 각 기구부로 공급하는 안내홀(6)과, 상기 냉동기유(13)를 펌핑하는 프로펠러(15)가 끝단부에 구성되었다.The crankshaft 2 is rotatably supported in the middle of the frame 10, the rotor 1 fixed to the crankshaft 2, and the rotor 1 and a proper gap. It consists of a stator (4) fixed to the bottom of the frame 10 and the crankshaft (2) is a guide hole (6) for sucking up the refrigeration oil (13) under the sealed container (9) to supply to each mechanism And, the propeller 15 for pumping the refrigeration oil 13 was configured at the end.
그리고 상기 압축기구부는 프레임(10)의 상면에 고정지지되는 실린더(5)와, 크랭크샤프트(2)의 편심부(16)에 슬라이더(3)를 장착한 피스톤쉘(12)과, 상기 피스톤쉘(12)에 의해 실린더(5)내에서 왕복운동을 하는 피스톤(11)으로 구성되었다.The compressor mechanism includes a cylinder 5 fixed to the upper surface of the frame 10, a piston shell 12 having a slider 3 mounted on an eccentric portion 16 of the crankshaft 2, and the piston shell. (12), it consists of the piston (11) which reciprocates in the cylinder (5).
이와같이 구성된 상태에서 밀폐형 전동압축기에 전원이 인가됨에 따라 회전자(1)의 회전과 동시에 크랭크샤프트(2)가 회전하게 되고 크랭크샤프트(2)의 편심부(16)에 슬라이더(3)의 개재하에 결합된 피스톤(11)이 실린더(5)의 내부에서 슬라이더(3)을 통해 왕복운동하면서 냉매가스를 흡입하여 압축 및 토출시키는 압축사이클을 이루게 된다.As the power is applied to the hermetic electric compressor in this configuration, the crankshaft 2 rotates at the same time as the rotor 1 rotates, and the eccentric portion 16 of the crankshaft 2 is interposed with the slider 3. The combined piston 11 achieves a compression cycle in which the refrigerant gas is sucked, compressed and discharged while reciprocating through the slider 3 in the cylinder 5.
한편 상기한 바와 같은 일반적인 밀폐형 전동압축기에는 그 동작시 각 기구부의 주요 마찰부에 냉동기유(13)를 공급하여 각 기구부의 동작을 보다 원활하게 하는 급유장치가 구비되는바 밀폐용기 저부에 저장된 냉동기유(13)는 크랭크샤프트(2)의 회전에 따라 그의 원심력 및 프로펠러(15)의 펌핑력으로 크랭크샤프트(2)의 내부안내홀(6)을 따라 흡상하여 각 기구부의 주요 마찰부에 공급하여 냉각 및 윤활작용을 하게 된다.Meanwhile, the general hermetic electric compressor as described above is provided with a lubrication device for supplying the refrigeration oil 13 to the main friction part of each mechanism part during its operation to make the operation of each mechanism part more smooth. 13 is drawn along the inner guide hole 6 of the crankshaft 2 by the centrifugal force and the pumping force of the propeller 15 according to the rotation of the crankshaft 2 and supplied to the main friction portion of each mechanism part to cool it. And lubrication.
그러나 크랭크샤프트(2)의 회전시 냉동기유(13)가 크랭크샤프트(2)의 내부안내홀(6)로 흡상함과 동시에 크랭크샤프트(2) 끝단의 외경 곡면부 주위에서 회전되면서 와류현상이 형성되고 이렇게 형성된 냉동기유의 와류형상은 냉동기유 와류음을 발생시켜 밀폐형 전동 압축기의 이상소음의 원인이 되는 문제점이 있었다.However, when the crankshaft 2 rotates, the coolant oil 13 sucks into the inner guide hole 6 of the crankshaft 2 and rotates around the outer diameter curved portion of the end of the crankshaft 2 to form a vortex phenomenon. And the vortex shape of the refrigerator oil thus formed has a problem that causes the abnormal noise of the hermetic electric compressor by generating the vortex sound of the refrigerator oil.
본 고안은 이러한 점을 감안하여 크랭크샤프트의 하단부에 외경이 직선형상으로 형성된 피스내경에 프로펠러의 장착을 위한 단턱부를 구비함으로서, 크랭크샤프트의 회전에 의한 냉동기유의 와류현상을 방지하여 냉동기유와류음을 저감시키도록 하는데 목적이 있다.The present invention has a stepped portion for mounting the propeller at the inner diameter of the crankshaft in which the outer diameter is linearly formed at the lower end of the crankshaft. The purpose is to reduce.
본 고안을 제3도 및 제4도에 의하여 설명한다.The invention is illustrated by FIGS. 3 and 4.
프레임(110)의 중간부에 회전가능하도록 지지되는 크랭크샤프트(100)와, 상기 크랭크샤프트(100)에 고정된 회전자(106)와, 상기 회전자(101)와 적정간극을 유지하며 프레임(110) 하부에 고정된 고정자(107)와, 밀폐용기(105)하부의 냉동기유(104)를 각 기구부로 공급하는 안내홀(108)과, 상기 냉동기유(104)를 펌핑하는 프로펠러(102)가 끝단부에 구성된 밀폐형 전동 압축기에 있어서, 크랭크샤프트(100)의 끝단부를 절단한후 여기에 냉동기유(104)의 와류현상을 방지하도록 외경이 직선형상으로 형성된 피스(101)를 압입하고, 상기 피스(101) 내부에는 프로펠러(102)를 삽입하며, 상기 프로펠러(102)가 피스(101)내에 삽입된 후 충격등에 의해서 탈거되지 않도록 단턱(103)을 내경에 형성하였다.The crankshaft 100 is rotatably supported in the middle of the frame 110, the rotor 106 fixed to the crankshaft 100, and maintains a proper clearance with the rotor 101 and the frame ( 110, a stator 107 fixed to the lower portion, a guide hole 108 for supplying the refrigeration oil 104 under the sealed container 105 to each mechanism part, and a propeller 102 for pumping the refrigeration oil 104. In the hermetic type electric compressor configured at the end portion, the end portion of the crankshaft 100 is cut and then press-fits the piece 101 having a linear outer diameter to prevent the vortex phenomenon of the refrigeration oil 104. The propeller 102 is inserted into the piece 101, and the stepped 103 is formed in the inner diameter so that the propeller 102 is not removed by an impact lamp after being inserted into the piece 101.

It does not occur.
그리고 상기의 프로펠러(102)는 피스(101) 내경에 형성된 단턱(103)에 걸쳐 끼워짐으로 외부충격에 의해서 이탈되는 것을 방지할 수 있는 것이다.And the propeller 102 is to be prevented from being separated by an external impact by fitting over the step 103 formed in the inner diameter of the piece 101.
이와같은 본 고안은 냉동기유의 와류현상이 발생하지 않으므로 냉동기유 와류음을 방지하여 밀폐형 전동압축기의 신뢰성 향상과 압축기의 이상소음을 해결할 수 있는 고안이다.The present invention is designed to solve the improvement of the reliability of the hermetic electric compressor and the abnormal noise of the compressor by preventing the vortex of the refrigeration oil because the vortex of the refrigeration oil does not occur.
