본 고안은 왕복동식 압축기에 관한 것으로, 충분한 냉매가스를 흡입하여 냉동효율을 향상하도록 한 왕복동식 압축기에 관한 것이다.The present invention relates to a reciprocating compressor, and relates to a reciprocating compressor to suck a sufficient refrigerant gas to improve the refrigeration efficiency.
종래의 왕복동식 압축기는 제1도에 도시된 바와 같이 모터(도시되지 않음)에 연결된 편심축(3)이 회전함에 따라 실린더(1)내의 피스톤(2)이 상하왕복운동을 하도록 되어 있다.In the conventional reciprocating compressor, as shown in FIG. 1, the piston 2 in the cylinder 1 moves up and down as the eccentric shaft 3 connected to the motor (not shown) rotates.
상기 편심축(3)이 회전함에 따라 피스톤(2)이 하향이동하면 흡입밸브(5)가 열리면서 흡압파이프(4)를 통하여 냉매가스가 압축실(8)로 들어온다.When the piston 2 moves downward as the eccentric shaft 3 rotates, the suction valve 5 opens and the refrigerant gas enters the compression chamber 8 through the suction pipe 4.
그리고, 편심축(3)이 계속 회전하게 되면 피스톤(2)이 하사점에서 상향이동하면 흡입밸브(5)는 닫히고 압축실(8)내에 흡입된 냉매가스의 압축이 시작된다.When the eccentric shaft 3 continues to rotate, the suction valve 5 closes when the piston 2 moves upward from the bottom dead center, and compression of the refrigerant gas sucked into the compression chamber 8 starts.
피스톤(2)의 상향이동에 따라 일정압력에 도달하면 토출밸브(6)가 열리고 압축된 냉매가스는 압축실(8)에서 토출되어 토출파이프(7)를 통하여 토출 된다.When a certain pressure is reached as the piston 2 moves upward, the discharge valve 6 is opened and the compressed refrigerant gas is discharged from the compression chamber 8 and discharged through the discharge pipe 7.
이러한 구성의 왕복동식 압축기에서는 피스톤(2)의 이동에 의한 압축실의 용적 변화에 의해 압축실의 압력을 떨어뜨려 흡입밸브(5)에 개방에 의해서만 냉매가스를 흡입한다.In the reciprocating compressor having such a configuration, the pressure in the compression chamber is reduced due to the volume change of the compression chamber due to the movement of the piston 2, and the refrigerant gas is sucked only by opening the suction valve 5.
따라서, 피스톤이 고속으로 왕복동하는 압축기에서는 흡입되는 냉매가스의 량이 충분하지 못한 결점이 있다.Therefore, there is a drawback that the amount of refrigerant gas sucked in the compressor in which the piston reciprocates at high speed is not sufficient.
따라서, 본 고안은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 흡입행정시 냉매가스가 과흡입되도록하여 냉동능력을 증가시켜 효율을 향상할 수 있는 왕복동식 압축기의 제공을 목적으로 한다.Accordingly, an object of the present invention is to provide a reciprocating compressor capable of improving the efficiency by increasing the refrigerating capacity by allowing the refrigerant gas to be sucked in during intake stroke.
상기 목적을 달성하기 위해 본 고안의 왕복동식 압축기는 피스톤 하부에 냉매가스를 흡입할 수 잇는 과충진부를 설치하고, 흡입밸브와 과충진부를 연통시켜 냉매가스를 과흡입되도록 한 것을 특징으로 한다.In order to achieve the above object, the reciprocating compressor of the present invention is characterized in that the overfill portion capable of sucking the refrigerant gas is installed in the lower part of the piston, and the suction valve and the overcharge portion communicate with each other to overtake the refrigerant gas.
과충진부의 상부에는 냉매가스가 흡입, 배출할 수 있는 구멍이 형성되면 효과적이다.It is effective to form a hole in the upper portion of the overfilling section for the refrigerant gas to be sucked in and discharged.
이하, 첨부도면에 의거하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안의 왕복동식 압축기의 일실시예를 나타낸다.2 shows an embodiment of the reciprocating compressor of the present invention.
과충진부(109)는 피스톤(102)의 하부에 밀폐 설치되어 있고, 피스톤(102)의 압축/흡입 행정시에 각각 개방/폐쇄되는 밸브(110)를 구비하고 있다.The overfill part 109 is sealed in the lower part of the piston 102, and is provided with the valve 110 which opens / closes at the time of the compression / suction stroke of the piston 102, respectively.
상기 과충진부(109)의 상부에 형성된 구멍(111)은 피스톤(102)의 왕복운동에 의해 과충진부(109)의 상부용적의 변화시 상기 구멍(111)을 통해 냉매가스가 흡입/배출되어 압력변동을 방지하여 편심축(109)을 구동하는 모터의 부하를 저감하는 역할을 한다.The hole 111 formed in the upper portion of the overfill portion 109 is the refrigerant gas is sucked / discharged through the hole 111 when the upper volume of the overfill portion 109 is changed by the reciprocating motion of the piston (102) It serves to reduce the load of the motor for driving the eccentric shaft 109 by preventing the pressure fluctuation.
한편 과충진부(109)는 연통통로(112)에 의해 흡입밸브(105)와 연통하여 흡입밸브(105)의 개방시 과충진부(109)의 냉매가스는 흡입밸브(105)를 거쳐 압축실(108)로 들어갈 수 있도록 되어 있다.On the other hand, the overfill unit 109 communicates with the intake valve 105 by the communication passage 112, and when the intake valve 105 is opened, the refrigerant gas of the overfill unit 109 passes through the intake valve 105 in the compression chamber. It is possible to enter (108).
또한 피스톤(102)는 압축실(108)과 접하는 상부면(102b)보다 크게 형성되어 상기 과충진부(109)와 접하는 하부면(102a)를 구비하고 있어, 과충진부(109)의 냉매가스가 직접 압축실(108)로 유입되는 것을 방지하고 있다.In addition, the piston 102 is formed to be larger than the upper surface 102b in contact with the compression chamber 108 and has a lower surface 102a in contact with the overfill 109. Is prevented from directly flowing into the compression chamber 108.
상기와 같이 구성된 본 고안의 작용을 설명한다.It describes the operation of the present invention configured as described above.
모터의 구동에 의해 편심축(103)이 회전하면 편심축(103)에 연결된 피스톤(102)이 상하 왕복운동을 하게 된다.When the eccentric shaft 103 is rotated by the driving of the motor, the piston 102 connected to the eccentric shaft 103 is vertically reciprocated.
피스톤(102)이 상향이동하는 압축/토출행정시 과충진부(109)의 용적이 팽창되어 압력이 저하되면 과충진밸브(110)가 개방되어 냉매가스가 과충진부(109)내부로 흡입된다.If the pressure of the overfill unit 109 expands and the pressure decreases during the compression / discharge stroke of the piston 102 moving upward, the overfill valve 110 is opened and the refrigerant gas is sucked into the overcharge unit 109. .
상기 피스톤(102)이 상사점에서 하향 이동하는 흡입행정시 과충진부(109)의 용적이 감소되어 압력이 상승되면 과충진밸브(110)는 폐쇄되고, 흡입밸브(105)가 개방되어 과충진부(109)의 냉매가스는 연통통로(112)를 통해 압축실(108)로 들어가게 된다.When the piston 102 moves downward at the top dead center, if the volume of the overfill unit 109 is reduced and the pressure is increased, the overfill valve 110 is closed and the intake valve 105 is opened to overfill. The refrigerant gas of the unit 109 enters the compression chamber 108 through the communication passage 112.
결국, 피스톤(102)의 왕복동에 의한 압축실(108)의 용적변화를 보다 과충진부(109)의 용적변화율이 더 크므로 결과적으로 냉매가스의 과흡입을 유도하게 되어 종래의 압축기보다 더 많은 냉매가스를 순환시켜 냉동능력을 증대시키며 효율을 향상시킬 수 있다.As a result, the volume change rate of the overfill portion 109 is larger than the volume change of the compression chamber 108 due to the reciprocation of the piston 102, resulting in over suction of the refrigerant gas, resulting in more than the conventional compressor. By circulating the refrigerant gas can increase the freezing capacity and improve the efficiency.
한편 피스톤 하부면(102a)와 실린더(101)과 과충진부(109)의 상부용적은 피스톤(102)의 왕복운동에 의해 변화되나, 과충진부(109)의 상부의 구멍(111)을 통해 가스가 흡입/배출되므로 압력변동이 방지되므로 편심축(103)을 구동하는 모터에 걸리는 부하를 줄여줄 수 있다.On the other hand, the upper volume of the piston lower surface 102a and the cylinder 101 and the overfill 109 is changed by the reciprocating motion of the piston 102, but through the hole 111 in the upper portion of the overfill 109 Since the gas is sucked / discharged, pressure fluctuations are prevented, thereby reducing the load on the motor driving the eccentric shaft 103.
이상과 같이 본 고안의 왕복동식 압축기에 따르면 압축실로 흡입되어 냉매가스의 량을 증대시켜 한 싸이클당 순환되는 냉매가스량을 증대시키므로 냉동능력을 증대할 수 있고 효율을 향상시킬 수 있다.As described above, according to the reciprocating compressor of the present invention, the amount of refrigerant gas that is sucked into the compression chamber to increase the amount of refrigerant gas circulated per cycle increases the refrigeration capacity and improves efficiency.
