본 고안은 냉장고용 압축기의 회전축 밸런스 구조에 관한 것으로, 좀더 구체적으로는 회전축의 회전력에 따른 최대 토오크와 최소 토오크의 격차를 좁혀 원활한 피스톤 왕복운동을 수행하며 동시에 소음 및 진동 감소에 효과적인 냉장고용 압축기의 회전축 밸런스 구조에 관한 것이다.The present invention relates to a rotating shaft balance structure of a compressor for a refrigerator, and more specifically, to close the gap between the maximum torque and the minimum torque according to the rotational force of the rotating shaft to perform a smooth piston reciprocating movement and at the same time effective in reducing the noise and vibration of the compressor. It relates to a rotating shaft balance structure.

종래의 냉매 압축장치는 단일의 피스톤과 실린더로 구성되어 회전축의 회전력을 피스톤이 전달받아 실린더내를 직선 왕복운동하므로써 냉매를 고압으로 압축하도록 되어 있었다.The conventional refrigerant compression device is composed of a single piston and a cylinder to compress the refrigerant to a high pressure by linearly reciprocating the cylinder by receiving the rotational force of the rotary shaft.

그러나 상기와 같은 구조는 회전축의 일측방에만 냉매를 압축시키는 피스톤과 실린더가 마련되어 있어 전체적인 구조가 비대칭형이므로 회전축의 회전시 최대토오크와 최소토오크의 차이가 커 초기 과부하로 인한 운전실패의 요인이 되었으며 또한 피스톤과 실린더가 편중되어 소음 및 진동이 과다한 문제점이 있어 바람직하지 않았다.However, the above structure has a piston and cylinder for compressing the refrigerant only on one side of the rotating shaft, so the overall structure is asymmetrical, so the difference between the maximum torque and the minimum torque during rotation of the rotating shaft is a factor of operation failure due to initial overload. In addition, pistons and cylinders are unfavorable due to excessive noise and vibration problems.

따라서, 본 고안의 목적은 상기와 같은 문제점을 감안하여 이를 해결하고자 안출한 것으로, 회전축의 양 측방에 각각 실린더와 보조실린더를 구성하고 이에 피스톤을 연결하여 그 구조가 좌우 대칭되게 하고 보조실린더내측에 스프링을 집어넣어 피스톤에 의해 압축시켜서, 보조실린더 내측의 스프링에 저장된 에너지를 이용하여 적은 회전력으로 냉매를 압축시킬 수 있으며, 실린더와 보조실린더 내부를 출입하는 각각의 피스톤 운동으로 최대, 최소 토오크 차이의 감소로 인한 진동감소효과와 이로인한 소음저감효과가 있는 냉장고용 압축기의 회전축 밸런스 구조를 제공하는 것이다.Therefore, the object of the present invention was devised to solve this problem in consideration of the above problems, and to form a cylinder and an auxiliary cylinder on each side of the rotating shaft and connect the piston to the left and right symmetrical structure and to the inside of the auxiliary cylinder By inserting the spring and compressing it by the piston, it is possible to compress the refrigerant with little rotational force by using the energy stored in the spring inside the auxiliary cylinder, and the maximum and minimum torque difference of each piston movement into and out of the cylinder and the auxiliary cylinder. It is to provide a rotating shaft balance structure of the compressor for a refrigerator having a vibration reduction effect and a noise reduction effect due to the reduction.

상기와 같은 목적을 달성하기 위한 본 고안의 형태는 회전축의 일축, 즉 실린더와 마주보는 프레임의 반대편에 실린더공이 천공된 보조실린더를 배치하고 이의 후방에 지지판을 부착하며, 상기 실린더공 내측에 스프링을 넣고 피스톤을 끼워 이를 회전축의 편심축에 연결하여 구동하도록 한 특징이 있다.A shape of the present invention for achieving the above object is to arrange an auxiliary cylinder in which the cylinder hole is perforated on one side of the axis of rotation, that is, the frame facing the cylinder, and attach a support plate to the rear of the cylinder, and a spring inside the cylinder hole. Insert a piston to connect it to the eccentric shaft of the rotating shaft to drive.

또한, 상기 지지판의 중앙, 즉 실린더공과 일치하는 부위에 냉매배출공을 마련하여 냉매를 용이하게 배출하도록 하여서 필요없이 냉매를 압축시키지 않도록 하여서 된 다른 특징이 있다.In addition, there is another feature of providing a refrigerant discharge hole in the center of the support plate, that is, coincident with the cylinder hole so that the refrigerant is easily discharged so as not to compress the refrigerant without need.

이하, 본 고안의 구성을 상세히 설명한다.Hereinafter, the configuration of the present invention will be described in detail.

도면의 제1도는 본 고안의 한 실시예를 나타낸 분리 사시도로, 회전축(40), 피스톤(52), 커넥팅로드(53), 실린더(50)등으로 구성되어 프레임(60)의 상부 일측에 설치된 압축기의 냉매압축장치에 상기 회전축(40)의 상단 편심축(41)의 길이를 일부 연장하고, 프레임(60)의 다른 일측, 즉 실린더(10)의 반대편에 실린더공(11)이 천공된 보조실린더(10)를 마련하여 보올트(12)로 프레임(60)에 고정하고 이의 후방에 지지판(30)을 보올트(32)로 고정하되 상기 실린더공(11)이 천공된 지지판(30)의 적소 위치에 상기 실린더공(11)보다 직경이 작은 크기로 냉매배출공(31)을 형성한 것이다.1 is an exploded perspective view showing an embodiment of the present invention, which is composed of a rotating shaft 40, a piston 52, a connecting rod 53, a cylinder 50, and the like, installed at an upper side of the frame 60. Part of the length of the upper eccentric shaft 41 of the rotary shaft 40 to the refrigerant compression device of the compressor, the auxiliary hole in which the cylinder hole 11 is drilled on the other side of the frame 60, that is, opposite the cylinder 10 The cylinder 10 is fixed to the frame 60 with the bolt 12 and the support plate 30 is fixed with the bolt 32 at the rear of the support plate 30 on which the cylinder hole 11 is perforated. The coolant discharge hole 31 is formed to have a diameter smaller than that of the cylinder hole 11 at a location.

그리고 상기 실린더공(11) 내측에 스프링(23)을 끼워넣고 피스톤(20)을 삽입시킨 다음, 그 길이가 연장된 편심축(41)에 커넥팅로드(21)의 축공(22)을 끼워 회전축(40)의 회전운동에 의해 상기 보조실린더(10)의 실린더공(11)으로 피스톤(20)이 직선 왕복운동하면서 출입하도록 한 것이다.Then, the spring 23 is inserted into the cylinder hole 11 and the piston 20 is inserted therein, and then the shaft hole 22 of the connecting rod 21 is inserted into the eccentric shaft 41 whose length is extended. The piston 20 moves in and out of the cylinder hole 11 of the auxiliary cylinder 10 by linear reciprocation by the rotational movement of 40.

도면의 제2도는 본 고안의 실시예를 나타낸 요부발췌 단면도로, 프레임(60)의 중앙에 회전축(40)이 관통되어 형성되고 실린더(50)를 출입하는 커넥팅로드(53)와 보조실린더(10)의 실린더공(11)을 출입하는 커넥팅로드(21)가 회전축(40)의 상단에 마련된 편심축(41)에 고정되며, 상기 보조실린더(10)의 실린더공(11) 내측에 스프링(23)이 배치되어 피스톤(20)의 왕복 운동에 의해 수축팽창 작용을 반복적으로 수행한다.FIG. 2 is a cross-sectional view of an essential part showing an embodiment of the present invention. The connecting rod 53 and the auxiliary cylinder 10 are formed by penetrating the rotating shaft 40 in the center of the frame 60 and enter and exit the cylinder 50. Connecting rod 21 entering and exiting the cylinder hole 11 of the () is fixed to the eccentric shaft 41 provided on the upper end of the rotating shaft 40, the spring 23 inside the cylinder hole 11 of the auxiliary cylinder 10 ) Is arranged to repeatedly perform the expansion and contraction action by the reciprocating motion of the piston (20).

도면중 미설명 부호 12는 실린더(50)를 프레임(60)에 고정하는 수단으로 보올트이고, 42는 상기 구조에서 윤활유를 급유하는 급유공이며, 55는 피스톤(52)에 의해 압축된 냉매를 배출하는 압축냉매 배출공, 70은 압축기의 커버이다.In the figure, reference numeral 12 is a means for fixing the cylinder 50 to the frame 60, 42 is an oil supply hole for lubricating oil in the structure, 55 is discharged refrigerant compressed by the piston 52 The compressed refrigerant discharge hole, 70 is a cover of the compressor.

상기와 같이 구성된 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in detail.

우선, 상기 구조의 작동과정을 도면의 제2도에서와 같이 모터(미도시)에 의해 회전(40)이 회전되고 편심축(41)에 연결된 커넥팅로드(21)(53)가 회전축(40)의 회전운동을 직선운동으로 바꾸어 주어 이에 연결된 각 피스톤(20)(52)이 실린더(50) 및 보조실린더(10) 내측을 직선 왕복운동하여 실린더(50) 내측에서 냉매를 흡입하여 고압으로 압축시켜 압축냉매 배출공(55)을 통하여 압축냉매를 내보내게 된다.First, as shown in FIG. 2 of the drawing, the connecting rods 21 and 53 connected to the eccentric shaft 41 are rotated by a motor (not shown). Change the rotational motion of the cylinder to linear motion, and each piston 20, 52 connected thereto linearly reciprocates the inside of the cylinder 50 and the auxiliary cylinder 10, sucks the refrigerant from the inside of the cylinder 50, and compresses it to high pressure. Compressed refrigerant is discharged through the compressed refrigerant discharge hole (55).

그리고, 상기 보조실린더(10)의 내측, 즉 실린더공(11)에서는 피스톤(20)이 직선왕복운동을 하면서 스프링(23)을 압축시켜 에너지를 저장하고 또 스프링(23)은 피스톤(20)에 의해 저장된 에너지를 피스톤(20)이 후퇴시, 즉 실린더(50)내의 냉매를 압축시킬 때 재공급하여 회전축(40)의 최대 토오크를 줄여주어 이의 회전을 돕는다.In addition, in the inner cylinder of the auxiliary cylinder 10, that is, the cylinder hole 11, the piston 20 compresses the spring 23 while linearly reciprocating to store energy, and the spring 23 is stored on the piston 20. The stored energy is supplied again when the piston 20 retreats, that is, when compressing the refrigerant in the cylinder 50 to reduce the maximum torque of the rotating shaft 40 to help its rotation.

참고로 지지판(30)에 형성된 냉매배출공(31)은 피스톤(20)과 스프링(23)이 고속으로 운동할 때 냉매의 압축을 배제시키는 역할을 한다. 그리고, 상기 보조실린더(10)내의 스프링(23)에 에너지를 저장시키려면 스프링(23)의 압축에 의한 손실이 뒤따르지만, 모터에 의한 회전축(40)의 회전시 부하가 줄어들어 과부하에 의한 모터의 고장으로부터 보호하여 준다.For reference, the refrigerant discharge hole 31 formed in the support plate 30 serves to exclude the compression of the refrigerant when the piston 20 and the spring 23 move at high speed. Then, in order to store energy in the spring 23 in the auxiliary cylinder 10, the loss due to the compression of the spring 23 is followed, but the load is reduced during the rotation of the rotary shaft 40 by the motor to reduce the load of the motor Protect from failure

또한, 압축기의 최초 작동시 첫단계에서 모터에 엄청난 부하가 걸려 있어 모터의 회전력 부족으로 인해 종종 기동실패의 요인이 되기도 하는데, 본 고안에서는 피스톤(20)(52)이 작동하기 위한 최대토오크와 최소토오크의 격차를 스프링(23)의 압축력 및 복원력에 따른 에너지를 이용하여 줄여주므로 압축기의 최초 기동실패가 발생하지 않는다.In addition, the initial load of the compressor in the first stage of the load on the motor is often a factor of failure due to the lack of rotational power of the motor, in the present design, the maximum torque and minimum for the piston 20, 52 to operate Since the torque gap is reduced by using the energy according to the compression force and the restoring force of the spring 23, the initial starting failure of the compressor does not occur.

또한, 상기 회전축(40)을 중심으로 대칭구조이고 각 피스톤(20)(52)의 직선운동이 서로 반대로 이루어져 압축기의 작동시 어느 한 부위에 집중적인 힘이 분포되지 않고 분산되므로 소음 및 진동이 현저하게 줄어든다.In addition, since the symmetrical structure around the rotating shaft 40 and the linear movement of each piston 20, 52 is opposite to each other, the noise and vibration are remarkable since the concentrated force is not distributed to any part during the operation of the compressor. Is reduced.

이상 살펴본 본 고안의 바람직한 형태에 따르면 피스톤(20)(52)의 직선 왕복운동시 스프링(23)의 압축 및 복원력에 의해 최대토오크와 최소토오크의 격차가 줄어들어 적은 회전력으로도 원활하게 냉매의 압축이 가능하고 또한 기동시에도 기동실패가 방지되며 대칭적인 구성으로 각 피스톤(20)(52)의 상호간에 소음 및 진동의 상쇄효과가 있어 소음과 진동이 현저히 줄어드는 등의 장점이 있는 신규유용한 고안인 것이다.According to the preferred form of the present invention described above, the gap between the maximum torque and the minimum torque is reduced by the compression and restoring force of the spring 23 during the linear reciprocating motion of the piston 20, 52, so that the compression of the refrigerant is performed smoothly even with a small rotational force. It is possible to prevent the starting failure even at the start and the symmetrical configuration of each piston (20, 52) of the mutually effective effect of canceling the noise and vibration is a new useful design with the advantage that the noise and vibration is significantly reduced. .
