It consists of a lubricating oil discharge path 62e which penetrates toward the furnace casing 10.

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

즉, 왕복동식 모터(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 공진스프링 유니트(50)에 의해 지속적으로 왕복운동을 하고, 이와 함께 피스톤(42)이 실린더(41)의 내부에서 왕복운동을 하면서 압축공간(P)의 체적이 변화하여 냉매가스를 압축공간으로 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 is formed. As the placed mover 33 moves in the direction of the flux, the reciprocating motion is continuously reciprocated by the resonant spring unit 50, and together with the piston 42 reciprocating in the cylinder 41, the compression space P ) Volume is changed, and a series of processes of suction and compression of refrigerant gas into the compression space and discharge are repeated.

이때, 피스톤(42)의 왕복운동에 의한 진동으로 윤활유 펌핑부(61)에 의해 케이싱(10)의 윤활유를 펌핑하고, 이 윤활유는 윤활유 공급유로부(62)의 윤활유흡입로(62a)를 통해 제1 윤활유포켓(62b)과 윤활유연통구(62c)와 제2 윤활유포켓(62d)으로 유입하면서 피스톤(42)과 실린더(41) 사이의 미끄럼부를 윤활한다.At this time, the lubricating oil of the casing 10 is pumped by the lubricating oil pumping unit 61 by the vibration caused by the reciprocating motion of the piston 42, and the lubricating oil is supplied through the lubricating oil suction passage 62a of the lubricating oil supply passage 62. The sliding portion between the piston 42 and the cylinder 41 is lubricated while flowing into the first lube oil pocket 62b, the lube oil communication port 62c, and the second lube oil pocket 62d.

이후, 피스톤(42)과 실린더(41) 사이를 윤활한 윤활유는 다시 윤활유연통구(62c)와 제1 윤활유포켓(62b)을 거친후 윤활유토출로(62e)를 통해 케이싱(10)으로 비산되면서 회수되는 것이었다.Subsequently, the lubricating oil lubricated between the piston 42 and the cylinder 41 passes through the lubricating oil communication port 62c and the first lubricating oil pocket 62b and then scatters into the casing 10 through the lubricating oil discharge path 62e. It was to be recovered.

그러나, 상기와 같은 종래 왕복동식 압축기에 있어서는, 윤활유토출로(62e)를 통해 비산하는 윤활유가 펌핑력에 의해 케이싱(10)으로 강하게 튀기면서 충돌소음을 유발하여 압축기 소음을 증가시키거나 또는 케이싱(10)에 충돌하여 비산하는 윤활유가 실린더(41)로 흡입되면서 압축기 효율을 저하시키는 문제점이 있었다.However, in the conventional reciprocating compressor as described above, the lubricating oil flying through the lubricating oil discharge path 62e is strongly splashed into the casing 10 by the pumping force, causing collision noise to increase the compressor noise or the casing ( There is a problem in that the compressor efficiency is lowered while the lubricating oil colliding with 10) is sucked into the cylinder 41.

본 발명은 상기와 같은 종래 왕복동식 압축기가 가지는 문제점을 감안하여 안출한 것으로, 실린더와 피스톤 사이의 윤활을 마친 윤활유가 케이싱으로 복귀할 때 생기는 윤활유의 충돌소음을 낮추고 비산하는 윤활유가 실린더로 흡입되는 것을 방지할 수 있는 왕복동식 압축기의 윤활유 안내 장치를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the conventional reciprocating compressor as described above, lubricating oil is lowered to the noise of lubricating oil generated when the lubricating oil lubricated between the cylinder and the piston is returned to the casing is sucked into the cylinder SUMMARY OF THE INVENTION An object of the present invention is to provide a lubricating oil guiding apparatus of a reciprocating compressor that can prevent the reciprocating compressor.

본 발명의 목적을 달성하기 위하여, 가동자가 직선으로 왕복운동을 하는 왕복동식 모터와, 왕복동식 모터와 함께 상기 프레임에 고정하는 실린더와, 실린더의 내주면에 미끄러지게 삽입하고 상기 왕복동식 모터의 가동자에 결합하여 직선 왕복운동을 하면서 냉매가스를 압축하는 피스톤과, 왕복동식 모터의 가동자와 피스톤을 연결하는 연결부의 전후 양측을 탄력지지하여 상기 가동자와 피스톤의 공진운동을 유도하는 복수 개의 공진스프링과, 프레임과 함께 진동하면서 케이싱 내의 윤활유를 펌핑하는 윤활유 펌핑부와, 윤활유 펌핑부에 연결하여 윤활유를 압축 유니트의 미끄럼부로 공급하도록 프레임 유니트에 형성하는 윤활유 공급유로부와, 윤활유 공급유로부의 토출측 끝단에 연통하여 윤활유를 케이싱의 저면으로 안내하는 윤활유 회수 안내부로 이루어진 것을 특징으로 하는 왕복동식 압축기의 윤활유 안내 장치를 제공한다.In order to achieve the object of the present invention, a reciprocating motor in which the mover linearly reciprocates, a cylinder fixed to the frame together with the reciprocating motor, and slides into the inner circumferential surface of the cylinder and moves the movable element of the reciprocating motor.

상기와 같은 본 발명 왕복동식 압축기의 윤활유 안내 장치는 다음과 같은 작용 효과를 갖는다.The lubricating oil guide device of the reciprocating compressor of the present invention as described above has the following effects.

즉, 왕복동식 모터(30)에 전원을 인가하여 플럭스(flux)를 형성하면, 가동자(33)가 플럭스의 방향에 따라 움직이면서 공진스프링 유니트(50)에 의해 지속적으로 왕복운동을 하고, 이와 함께 피스톤(42)이 실린더(41)의 내부에서 왕복운동을 하면서 냉매가스를 압축공간(P)으로 흡입 압축하였다가 토출한다.That is, when a flux is formed by applying power to the reciprocating motor 30, the mover 33 moves in the flux direction and continuously reciprocates by the resonant spring unit 50. The piston 42 suctions and compresses the refrigerant gas into the compression space P while reciprocating in the cylinder 41.

이 과정중에 윤활유 공급 유니트(60)의 윤활유 펌핑부(61)가 프레임 유니트(20)와 함께 진동하면서 케이싱(10) 내의 윤활유를 압축 유니트(40)로 펌핑하고, 이 윤활유는 윤활유 공급유로부(62)의 윤활유흡입로(62a)를 통해 제1 윤활유포켓(62b)과 윤활유연통구(62c)와 제2 윤활유포켓(62d)으로 유입하면서 피스톤(42)과 실린더(41) 사이의 미끄럼부를 윤활한 후 다시 윤활유연통구(62c)와 제1 윤활유포켓(62b)을 그리고 윤활유회수로(62e)와 윤활유회수구(62f)를 차례대로 통과한 다음에 윤활유 회수 안내부(63)를 통해 케이싱(10)의 저면으로 직접 배출되어 회수된다.During this process, the lubricating oil pumping part 61 of the lubricating oil supply unit 60 vibrates with the frame unit 20 to pump the lubricating oil in the casing 10 to the compression unit 40, and the lubricating oil is supplied to the lubricating oil supply passage part ( Lubricates the sliding portion between the piston 42 and the cylinder 41 while flowing into the first lube oil pocket 62b, the lube oil communication port 62c, and the second lube oil pocket 62d through the lube oil suction path 62a. After passing through the lubricating oil communication port 62c and the first lubricating oil pocket 62b, and then passing through the lubricating oil return path 62e and the lubricating oil return port 62f, the casing ( It is discharged and recovered directly to the bottom of 10).

이렇게 하여, 실린더와 피스톤의 윤활을 마친 윤활유가 케이싱으로 배출될 때에 케이싱에 부딪히는 것을 차단하거나 충돌력을 줄여 압축기 소음을 줄이는 것은 물론 배출되는 윤활유가 윤활유 회수 안내부를 따라 곧바로 케이싱 저면으로 회수됨에 따라 윤활유가 실린더로 흡입되는 것을 차단하여 압축기 효율을 높일 수 있다.In this way, when the lubricated oil of the cylinder and piston is discharged into the casing, it prevents it from colliding with the casing or reduces the impact force to reduce the compressor noise, as well as the discharged lubricating oil is recovered along the lubricating oil return guide straight to the bottom of the casing. Can be prevented from being sucked into the cylinder to increase the compressor efficiency.

본 발명에 의한 왕복동식 압축기의 윤활유 안내 장치는, 윤활유의 토출측 끝단에 윤활유 회수 안내부를 연통 설치하여 윤활유를 케이싱 저면으로 유도함으로써, 윤활을 마치고 배출되는 윤활유가 케이싱에 강하게 부딪히는 것을 방지하여 압축기 소음을 낮출 수 있을 뿐만 아니라 윤활유가 실린더로 흡입되는 것을 차단하여 압축기 효율을 높일 수 있다.The lubricating oil guide device of the reciprocating compressor according to the present invention connects the lubricating oil recovery guide part to the discharge side end of the lubricating oil and guides the lubricating oil to the bottom of the casing, thereby preventing the lubricating oil discharged after lubrication from being strongly hit by the casing to prevent compressor noise. Not only can it be lowered, but it can also block compressors from being sucked into the cylinder, increasing compressor efficiency.
