상기 압축기구부는 상기 크랭크축(6)의 상부에 형성되어 크랭크축(6)의 회전운동을 왕복운동으로 바꾸어주는 슬라이더(13)와, 상기 슬라이더(13)와 결합되는 피스톤(3)과, 상기 피스톤(3)이 왕복운동을 할 수 있도록 프레임(5)에 볼트로 체결되어진 실린더(2)와, 상기 실린더(2) 전면에 냉매가스의 흡입, 토출을 개폐하도록 형성되어진 밸브/헤드(12)와, 상기 밸브/헤드(12)와 결합되어지는 헤드카바(4)와, 상기 하부밀폐용기(1b)내에 담겨 있는 오일(9)과, 상기 오일(9)을 흡상시키도록 크랭크축(6)의 하단에 형성된 프로펠러(10)와, 상기 프로펠러(10)를 고정시키도록 하부 밀폐용기(1b)내에 형성된 피스(11)로 구성하였다.The compressor mechanism is formed on the upper part of the crankshaft 6, the slider 13 for changing the rotational movement of the crankshaft 6 to the reciprocating motion, the piston 3 is coupled to the slider 13, and A cylinder (2) bolted to the frame (5) to allow the piston (3) to reciprocate, and a valve / head (12) formed to open and close the suction and discharge of refrigerant gas on the front of the cylinder (2). And a crankshaft (6) for sucking up the head cover (4) coupled to the valve / head (12), the oil (9) contained in the lower airtight container (1b), and the oil (9). The propeller 10 formed at the lower end of the, and composed of a piece 11 formed in the lower hermetic container (1b) to fix the propeller (10).
이와같이 구성된 종래의 밀폐형 압축기에 전원이 인가되면 고정자(8)와 회전자(7)사이에 유도전류가 발생하여 회전자(7)가 회전하게 되고, 회전자(7)의 회전에 따라 회전자(7)에 압입된 크랭크축(6)이 회전하게 된다.When power is applied to the conventional hermetic compressor configured as described above, an induction current is generated between the stator 8 and the rotor 7 so that the rotor 7 rotates and the rotor 7 rotates according to the rotation of the rotor 7. The crankshaft 6 pressed into 7) rotates.
상기 크랭크축(6)의 상부에 형성된 슬라이더(13)는 크랭크축(6)의 회전운동으로 왕복운동으로 바꾸어주고, 상기 슬라이더(13)는 피스톤(3)에 결합되고, 상기 피스톤(3)은 실린더(2)내를 왕복운동한다.The slider 13 formed on the top of the crankshaft 6 is converted into a reciprocating motion by the rotational movement of the crankshaft 6, the slider 13 is coupled to the piston 3, the piston 3 is The cylinder 2 is reciprocated.
그리고 크랭크축(6)이 회전함에 따라 크랭크축(6)의 하단에 형성된 프로펠러(10)가 같이 회전하게 되고, 하부밀폐용기(1b)에 담겨 있는 오일(9)은 프로펠러(10)의 회전원심력에 의해 중공의 크랭크축(6)내부로 흡입되어진다.And as the crankshaft 6 rotates, the propeller 10 formed at the lower end of the crankshaft 6 rotates together, and the oil 9 contained in the lower airtight container 1b is a rotary centrifugal force of the propeller 10.

Sprayed.
그러나 이러한 종래의 밀폐형 압축기는 크랭크축의 회전속도가 줄어드는 경우 회전원심력에 비해 중력이 커지므로 오일이 원활이 흡상되지 못하고, 윤활이 필요한 각 윤활부위로 오일이 충분히 공급되지 못하여 각 윤활부위에 마모가 심해지는 문제점이 있었다.However, in the conventional hermetic compressor, when the rotational speed of the crankshaft decreases, gravity becomes larger than the rotational centrifugal force, so oil is not smoothly drawn up, and oil is not supplied sufficiently to each lubrication part that requires lubrication, and wear on each lubrication part becomes severe. Had a problem.
따라서 본 발명은 이를 감안하여 크랭크축 내부에 오일을 흡상시키기 위한 나선형축을 삽입고정시킴으로써, 크랭크축의 저속회전시 충분한 양의 오일을 흡상시켜 각 윤활부위에 공급하여 기구의 마모를 방지하는 데 그 목적이 있다.Therefore, in view of this, by inserting and fixing a spiral shaft for sucking oil inside the crank shaft, the present invention sucks a sufficient amount of oil during low-speed rotation of the crank shaft and supplies it to each lubrication part to prevent wear of the mechanism. have.

그리고 상기 나선형축(114)은 제 3 도와 같이 축부(114a)와, 상기 축부(114a)의 외주연에 형성된 나선형날개부(114b)로 구성된다.The spiral shaft 114 is composed of a shaft portion 114a and a spiral wing portion 114b formed at an outer circumference of the shaft portion 114a as a third diagram.
이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
먼저, 밀폐형 압축기에 전원이 인가되면 고정자(108)와 회전자(107)사이에 유도전류가 발생하여 회전자(107)가 회전하고, 상기 회전자(107)에 압입된 크랭크축(106)이 회전자(107)와 같이 회전하게 된다.First, when power is applied to the hermetic compressor, an induction current is generated between the stator 108 and the rotor 107 so that the rotor 107 rotates, and the crank shaft 106 press-fitted to the rotor 107 The rotor 107 rotates together.
상기 크랭크축(106)이 회전함에 따라 중공의 크랭크축(106) 하단에 형성된 프로펠러(110)와 크랭크축(106)내부에 삽입고정된 나선형축(114)도 같이 회전하여, 하부밀폐용기(101b)에 담겨 있는 오일이 프로펠러(110)의 회전을 통하여 크랭크축(106)내부로 흡입된다.As the crank shaft 106 rotates, the propeller 110 formed at the bottom of the hollow crank shaft 106 and the helical shaft 114 inserted into the crank shaft 106 are also rotated, thereby lowering the vessel 101b. The oil contained in) is sucked into the crankshaft 106 through the rotation of the propeller 110.
상기 흡입된 오일(109)은 나선형축(114)의 회전원심력뿐만 아니라 오일점성력에 의하여 나선형축(114)을 따라 크랭크축(106)의 상단부까지 흡상되어 윤활이 필요한 각 윤활부위에 공급된다.The sucked oil 109 is sucked up to the upper end of the crankshaft 106 along the spiral shaft 114 by the oil viscosity as well as the rotational centrifugal force of the spiral shaft 114, and is supplied to each lubrication portion that requires lubrication.
여기서 상기 나선형축(114)의 날개부(114b)는 유로를 일정폐쇄하는 기능을 가지고 있으므로 크랭크축(106)의 회전속도가 감소하여도 크랭크축(106)내부로 흡입된 오일(109)의 유실을 막음으로써 충분한 양의 오일(109)을 밀폐형 압축기의 각 윤활부위에 공급할 수 있게 된다.Here, the wing portion 114b of the helical shaft 114 has a function of closing the flow path so that the loss of oil 109 sucked into the crank shaft 106 even if the rotation speed of the crank shaft 106 decreases. By blocking the oil, a sufficient amount of oil 109 can be supplied to each lubrication portion of the hermetic compressor.
이상에서 설명한 바와 같이 본 발명은 크랭크축의 저속회전시 오일을 크랭크축내부에 삽입고정된 나선형축의 회전원심력에 의해 크랭크축의 상부로 흡상시켜, 밀폐형 압축기의 각 윤활부위에 공급함으로써 기구부의 마모를 방지하는 효과가 있다.As described above, the present invention sucks oil to the upper part of the crankshaft by the rotational centrifugal force of the spiral shaft fixed in the crankshaft at low speed rotation of the crankshaft, and supplies it to each lubrication part of the hermetic compressor to prevent wear of the mechanism part. It works.
