Abstract

본 발명은 왕복동식 압축기의 모터 냉각 구조에 관한 것으로, 본 발명은 왕복동식 압축기의 프레임유니트에는 윤활유공급유니트를 통해 펌핑된 윤활유를 권선코일로 유도하는 윤활유안내유로를 형성하고, 권선코일의 외주면에는 라미네이션 시트와의 사이에 상기 윤활유안내유로와 연통하는 윤활유통로를 형성함으로써, 윤활유가 권선코일에 직접 접촉하면서 회수될 수 있도록 함에 따라 권선코일에서 발생하는 모터열을 효과적으로 냉각하여 압축기 성능을 높일 수 있을 뿐만 아니라 윤활유의 낙하높이를 낮춰 윤활유의 회수시 발생하는 압축기 소음을 더욱 줄일 수 있다.The present invention relates to a motor cooling structure of a reciprocating compressor, and the present invention provides a frame unit of the reciprocating compressor to form a lubricating oil guide path for guiding lubricating oil pumped through the lubricating oil supply unit to the winding coil, and on the outer circumferential surface of the winding coil. By forming a lubricating oil passage communicating with the lubricating oil guiding flow path between the lamination sheet, the lubricating oil can be recovered while directly contacting the winding coil, thereby effectively cooling the motor heat generated in the winding coil and improving the compressor performance. In addition, it is possible to further reduce the compressor noise generated when the lubricant is recovered by lowering the drop height of the lubricant.

상기와 같은 종래 왕복동식 압축기는 다음과 같이 동작한다.The conventional reciprocating compressor as described above operates as follows.

즉, 왕복동모터(30)에 전원을 인가하여 외측고정자(31)와 내측고정자(32) 사이에 플럭스(flux)를 형성하면, 그 외측고정자(31)와 내측고정자(32) 사이의 공극에 놓인 가동자(33)가 플럭스의 방향에 따라 움직이면서 공진스프링유니트(50)에 의해 지속적으로 왕복운동을 하고, 이와 함께 피스톤(42)이 실린더(41)의 내부에서 왕복운동을 하면서 압축공간(P)의 체적이 변화하여 냉매가스를 압축공간(P)으로 흡입 압축하였다가 토출하는 일련의 과정을 반복한다.That is, when a flux is formed between the outer stator 31 and the inner stator 32 by applying power to the reciprocating motor 30, the gap between the outer stator 31 and the inner stator 32 lies in the gap. As the mover 33 moves in the direction of the flux, the resonant spring unit 50 continuously reciprocates, and the piston 42 reciprocates in the cylinder 41 while the compression space P The volume of is changed and a series of processes of suction and compression of the refrigerant gas into the compression space (P) is repeated.

이때, 프레임유니트(20)와 함께 진동하는 윤활유펌핑부(61)에 의해 케이싱(10)의 윤활유를 펌핑하고, 이 윤활유는 윤활유유로부(62)를 통과하면서 압축유니트(40)의 미끄럼부로 공급되었다가 다시 케이싱(10)으로 회수되는 것이었다.At this time, the lubricating oil of the casing 10 is pumped by the lubricating oil pumping part 61 vibrating with the frame unit 20, and the lubricating oil is supplied to the sliding part of the compression unit 40 while passing through the lubricating oil flow path 62. And then returned to the casing (10).

그러나, 상기와 같은 종래 왕복동식 압축기에 있어서는, 도 2에서와 같이 윤활유가 압축유니트(40)의 미끄럼부를 윤활한 후 케이싱(10)으로 회수됨에 따라 왕복동모터(30)의 최대 열원인 권선코일(34)을 직접 냉각하지 못하고 이로 인해 모터열이 가중되어 압축기 성능이 저하되는 문제점이 있었다.However, in the conventional reciprocating compressor as described above, as shown in FIG. 2, as the lubricating oil is lubricated by the sliding part of the compression unit 40 and recovered to the casing 10, the winding coil as the largest heat source of the reciprocating motor 30 ( There is a problem that the compressor performance is reduced due to the heat of the motor is not directly cooled due to 34).

본 발명은 상기와 같은 종래 왕복동식 압축기가 가지는 문제점을 감안하여 안출한 것으로, 윤활유가 왕복동모터의 권선코일을 직접 냉각할 수 있도록 하여 왕복동모터의 과열을 방지하고 이를 통해 왕복동식 압축기의 성능을 높일 수 있는 왕복동식 압축기의 모터 냉각 구조를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the conventional reciprocating compressor as described above, so that the lubricant can directly cool the winding coil of the reciprocating motor to prevent overheating of the reciprocating motor and thereby increase the performance of the reciprocating compressor. It is an object of the present invention to provide a motor cooling structure of a reciprocating compressor.

예컨대, 도 6에서는 권선코일(120)의 일부를 이루는 보빈체(121)의 외주면 양측에 소정 높이의 통로형성돌부(121a)를 돌출 형성하여 그 통로형성돌부(121a)에 라미네이션 시트 혹은 적층체(122)의 내측면이 밀착하도록 하여 상기한 통로형성돌부(121a)의 높이 만큼 높은 윤활유통로(R)를 형성하는 반면, 도 7에서는 라미네이션 시트 혹은 적층체(130)의 내측면 양측에 통로형성돌부(130a)를 소정 높이로 형성하여 그 양쪽 통로형성돌부(130a) 사이와 권선코일(120)의 보빈체(121) 외주면 사이에 상기한 윤활유통로(R)를 형성하도록 할 수 있다.For example, in FIG. 6, a passage forming protrusion 121a having a predetermined height is formed on both sides of the outer circumferential surface of the bobbin body constituting a part of the winding coil 120, and a lamination sheet or a laminate body is formed on the passage forming protrusion 121a.

상기와 같은 본 발명 왕복동식 압축기의 모터 냉각 구조는 다음과 같은 작용 효과를 갖는다.The motor cooling structure of the reciprocating compressor of the present invention as described above has the following effects.

즉, 왕복동모터(30)에 전원을 인가하여 외측고정자(31)와 내측고정자(32) 사이에 플럭스(flux)를 형성하면, 가동자(33)가 플럭스의 방향에 따라 움직이면서 공진스프링(52)(53)에 의해 지속적으로 왕복운동을 하고, 이와 함께 피스톤(42)이 실린더(41)의 내부에서 왕복운동을 하면서 냉매가스를 압축공간(P)으로 흡입 압축하였다가 토출하며, 이 과정에서 전방프레임(110)과 함께 진동하는 윤활유펌핑부(61)에 의해 케이싱(10)의 윤활유를 실린더(41)와 피스톤(42) 사이의 미끄럼부로 공급하고, 이 윤활유는 실린더(41)와 피스톤(42) 사이를 윤활한 다음 다시 전방프레임(110)의 윤활유안내유로(112)를 통해 왕복동모터(30)의 권선코일(120)로 공급되어 그 권선코일(120)을 직접 냉각한 후 케이싱(10)으로 회수되는 일련의 과정을 반복한다.That is, when a flux is formed between the outer stator 31 and the inner stator 32 by applying power to the reciprocating motor 30, the resonator spring 52 moves while the mover 33 moves in the direction of the flux. Continuously reciprocating by (53), with the piston 42 reciprocating in the cylinder 41 while suction refrigerant compressed to the compression space (P) and discharged, in the process of the front Lubricating oil of the casing 10 is supplied to the sliding portion between the cylinder 41 and the piston 42 by the lubricating oil pumping portion 61 vibrating with the frame 110, and the lubricating oil is supplied to the cylinder 41 and the piston 42. After lubricating between) and supplied back to the winding coil 120 of the reciprocating motor 30 through the lubricating oil guide passage 112 of the front frame 110 to directly cool the winding coil 120 and then the casing 10 Repeat a series of steps to recover.

여기서, 전방프레임(110)의 윤활유안내유로(112)를 통해 권선코일(120)과 라미네이션 시트 또는 적층체(130) 사이의 윤활유통로(R)로 공급된 윤활유는 그 권선코일(120), 즉 보빈체(121)의 외주면에 직접 접촉됨에 따라 보빈체(121) 내부의 코일(122)에서 발생되는 모터열을 효과적으로 냉각할 수 있다.Here, the lubricating oil supplied to the lubricating oil passage R between the winding coil 120 and the lamination sheet or the laminate 130 through the lubricating oil guide passage 112 of the front frame 110 is the winding coil 120, that is, By directly contacting the outer circumferential surface of the bobbin body 121, the motor heat generated in the coil 122 inside the bobbin body 121 may be effectively cooled.

또, 윤활유가 피스톤(42)의 중심선 보다 높은 위치에서 비산됨에 따라 케이싱(10)에 부딪히거나 높은 곳에서 자유낙하 하면서 압축기 소음을 가중시킬 수 있으나, 본 발명에서와 같이 윤활유가 상기한 보빈체(121)의 외주면을 따라 흘러내리다가 피스톤(42)의 중심선 부근에서 자유낙하 하거나 라미네이션 시트 혹은 적층체(130)를 따라 더 낮은 곳까지 흘러내리면서 케이싱(10)으로 회수되어 윤활유에 의한 압축기 소음을 보다 효과적으로 줄일 수 있다.In addition, as the lubricant is scattered at a position higher than the centerline of the piston 42, the compressor noise may be increased while colliding with the casing 10 or falling freely at a high place. It flows down along the outer circumferential surface of the 121 and free-falls near the center line of the piston 42, or flows down to a lower position along the lamination sheet or the laminate 130, and is recovered to the casing 10, thereby causing compressor noise by lubricating oil. Can be reduced more effectively.

본 발명에 의한 왕복동식 압축기의 모터 냉각 구조는, 전방프레임에 윤활유를 권선코일의 상측으로 유도하는 윤활유안내유로를 형성함과 아울러 권선코일의 외주면과 라미네이션 시트 혹은 적층체 사이에 윤활유통로를 형성함으로써, 윤활유가 권선코일에 직접 접촉하면서 회수될 수 있도록 함에 따라 권선코일에서 발생하는 모터열을 효과적으로 냉각하여 압축기 성능을 높일 수 있을 뿐만 아니라 윤활유의 낙하높이를 낮춰 윤활유의 회수시 발생하는 압축기 소음을 더욱 줄일 수 있다.The motor cooling structure of the reciprocating compressor according to the present invention forms a lubricating oil passage in the front frame to guide the lubricating oil to the upper side of the winding coil, and also forms a lubricating oil passage between the outer circumferential surface of the winding coil and the lamination sheet or the laminate. As the lubricating oil can be recovered while directly contacting the winding coil, it can effectively cool the motor heat generated from the winding coil to improve the compressor performance and lower the drop height of the lubricating oil to further reduce the compressor noise generated when the lubricating oil is recovered. Can be reduced.
