(5) is provided with an electric mechanism unit, the lower portion of the inner surface of the container (1), the rotary shaft (7) is press-fit fixed to the inner diameter of the rotor (5), and the lower portion of the rotary shaft (7) an upper bearing ( 10) and the bearing (9) consists of a cylinder (6) coupled with a bolt (11), the cylinder (6) being coupled to an eccentric shaft and rotating while contacting the inner diameter of the cylinder (6). And a vane 20 formed in contact with the roller 8 to form a compression space of the compression chamber and the suction chamber.
상기 용기(1)의 상단부에는 토출관(18)이 연결되고, 외측벽 하부에는 어큐뮬레이터(19)로 부터 냉매가스를 흡입하는 흡입관(17)이 설치되어 있다.A discharge pipe 18 is connected to the upper end of the container 1, and a suction pipe 17 for sucking refrigerant gas from the accumulator 19 is installed below the outer wall.
상기 압축기구부의 실린더(6)의 상단부 및 하단부에는 각각 상베어링(10) 및 하베어링(9)이 볼트(11)에 의해 고정되어 실린더(6)내의 밀폐공간을 형성한다.The upper bearing 10 and the lower bearing 9 are respectively fixed to the upper end and the lower end of the cylinder 6 of the compression mechanism by bolts 11 to form a sealed space in the cylinder 6.
상기 상베어링(10)에는 실린더(6)내의 밀폐공간에서 압축된 냉매가스를 배출하기 위한 토출밸브(22)가 형성되어 있고, 이 토출밸브(22)는 실린더(6) 내부의 압력에 따라 개폐되며, 그 행정은 토출밸브(22) 상단에 설치된 리테이너(23)에 의해 제한되며, 상기 상베어링(10)에는 상기 토출밸브(22)를 거쳐 배출되는 냉매가스의 맥동음을 감소시키기 위한 소음기(15)가 설치되어 있다. 그리고 이 소음기(15)의 상면에는 소음기(15)를 거친 냉매가스가 빠져나가는 토출구(도면에 도시되지 않음)가 용기의 내면 상부를 향하도록 형성되어 있다.The upper bearing 10 has a discharge valve 22 for discharging the compressed refrigerant gas in a closed space in the cylinder 6, the discharge valve 22 is opened and closed in accordance with the pressure in the cylinder (6) The stroke is limited by the retainer 23 installed at the upper end of the discharge valve 22, the upper bearing 10 has a silencer for reducing the pulsation sound of the refrigerant gas discharged through the discharge valve 22 ( 15) is installed. And the upper surface of this muffler 15 is formed so that the discharge port (not shown) which the refrigerant gas which passed through the muffler 15 escapes may face the upper part of the inner surface of a container.
용기(1)의 상부에 형성된 토출관(18)을 통해 토출된 고온 고압의 냉매가스는 냉동싸이클을 구성하는 응축기(12)와 캐피라리 튜브(13) 및 증발기(14)를 지나 압축기의 어큐물레이터(19)를 지나 밀폐용기에 고정된 흡입관(17)을 통하여 상기 실린더(6)내의 밀폐공간으로 유입되도록 냉동싸이클이 구성된다.The high temperature and high pressure refrigerant gas discharged through the discharge tube 18 formed in the upper part of the container 1 passes through the condenser 12, the capillary tube 13, and the evaporator 14 constituting the refrigeration cycle, and accumulates the compressor. The refrigeration cycle is configured to enter the sealed space in the cylinder 6 through the suction pipe 17 fixed to the sealed container through the radar 19.
상기와 같이 구성된 종래의 기술에 의한 밀폐형 회전 압축기의 작동은 다음과 같다.The operation of the hermetic rotary compressor according to the related art configured as described above is as follows.
먼저 증발기(14)로부터 유입된 저온 저압의 냉매 가스는 어큐물레이터(19)내에서 기액분리가 되어 기체상태의 냉매가스만 흡입관(17)을 통해 흡입된다. 실린더(6) 내부의 밀폐공간으로 흡입된 냉매가스는 롤러(8)의 회전에 의해 실린더(6)내에서 압축되고, 일정 압력이상으로 압축된 냉매가스는 상베어링(10)에 형성된 토출밸브(22)를 통해 소음기(15)쪽으로 배출된다. 이 소음기(15) 내에서는 냉매가스의 맥동음이 제거되고, 소음기(15) 상단에 형성된 토출구를 거쳐 냉매가스가 토출된다. 이때 토출된 냉매가스는 회전자(5)와 고정자(4)의 틈새를 통하여 용기(1)상부에 있는 토출관(18)을 통해 압축기로부터 토출된다. 밀폐용기내의 고온 고압 냉매가스는 토출관을 지나 응축기에서 주위로 열을 방출하여 고압의 액체냉매로 만들고 이 액체 냉매는 캐피라리 튜브를 지나면서 저온전압의 액체냉매가 되고 증발기를 지나면서 주위의 열을 흡수하여 저온전압의 기체냉매가 되어 압축기의 어큐물레이터로 유입되는 냉동싸이클을 순환하게 된다.First, the low-temperature low-pressure refrigerant gas introduced from the evaporator 14 is gas-liquid separated in the accumulator 19 so that only the refrigerant gas in the gas state is sucked through the suction pipe 17. The refrigerant gas sucked into the sealed space inside the cylinder (6) is compressed in the cylinder (6) by the rotation of the roller (8), and the refrigerant gas compressed to a predetermined pressure or more is discharge valve formed in the upper bearing (10) 22) is discharged toward the muffler (15). In this muffler 15, the pulsation sound of the refrigerant gas is removed, and the refrigerant gas is discharged through the discharge port formed in the top of the muffler 15. At this time, the discharged refrigerant gas is discharged from the compressor through the discharge pipe 18 located above the container 1 through the gap between the rotor 5 and the stator 4. The high-temperature high-pressure refrigerant gas in the sealed container passes through the discharge tube and discharges heat from the condenser to the high-pressure liquid refrigerant. The liquid refrigerant passes through the capillary tube to become a low-temperature liquid refrigerant and passes through the evaporator to the surrounding heat. It absorbs and becomes a gas refrigerant at low temperature, thereby circulating the refrigeration cycle flowing into the accumulator of the compressor.
실린더(6)내에서 압축된 냉매가스가 소음기(15)방향으로 배출되는 과정을 상술하면, 실린더(6)내의 상베어링(10)과 하베어링(9)과 롤러(8)에 의해 형성된 공간이 회전축(7) 편심부의 편심에 의해 일정지점까지 지속적으로 압축되어, 압축가스가 임계한도를 지났을 때 토출밸브(22)를 밀게 된다. 토출 가스의 힘에 의해 토출밸브(22)는 리테이너(23)를 강제로 밀게 되고, 실린더(6) 내부의 압력이 저하되었을 때 다시 토출밸브(22)는 닫히게 되어 다음 임계압력까지 밀폐작용을 하게 된다.Referring to the process in which the refrigerant gas compressed in the cylinder 6 is discharged in the direction of the muffler 15, the space formed by the upper bearing 10, the lower bearing 9 and the roller 8 in the cylinder 6 The rotary shaft 7 is continuously compressed to a certain point by the eccentricity of the rotary shaft 7, and pushes the discharge valve 22 when the compressed gas passes the critical limit. The discharge valve 22 forcibly pushes the retainer 23 by the force of the discharge gas, and when the pressure inside the cylinder 6 decreases, the discharge valve 22 is closed again to close the valve until the next critical pressure. do.
밀폐형 회전식 압축기의 회전자(5)와 고정자(4)에 의하여 회전축(7)이 1회전 할때마다 실린더(8)내의 압축실에는 고압이 발생하며, 이때 발생한 고압이 토출 밸브(22)가 누르는 힘보다 크게 될 때 토출 밸브(22)가 열리게 되고, 압력이 낮아지면 닫히게 됨에 따라 1회전당 한번씩의 개폐운동이 발생한다.When the rotary shaft 7 rotates once by the rotor 5 and the stator 4 of the hermetic rotary compressor, a high pressure is generated in the compression chamber in the cylinder 8, and the high pressure generated is pressed by the discharge valve 22. The discharge valve 22 is opened when it is larger than the force, and when the pressure is lowered, the discharge valve 22 is closed, so that the opening and closing movement is performed once per revolution.
그러나, 이러한 종래의 기술에서는 증발기(14)는 저납의 액체냉매를 증발시켜 저압의 가스상태의 냉매로 변환시켜 압축기의 흡입관(17)으로 흡입되도록 해야 하나, 현실적으로 어려우며 특히 압축기 운전초기에는 증발기의 역활을 할 수 없으므로 액냉매가 상당시간 흡입관(17)으로 유비되는 문제가 있다. 상기의 문제점을 해결하기 위해 기액분리기능을 가진 어큐물레이터(19)의 용량을 대단히 크게해야 하나, 에어컨에 취부시 압축기의 구조가 커짐에 따라 에어컨을 크게 만들어야 하는 문제점이 있다.However, in the conventional technology, the evaporator 14 has to evaporate the low-lead liquid refrigerant and convert it into a low-pressure gaseous refrigerant to be sucked into the suction pipe 17 of the compressor. There is a problem that the liquid refrigerant is likened to the suction pipe 17 for a considerable time. In order to solve the above problems, the capacity of the accumulator 19 having a gas-liquid separation function should be made very large, but there is a problem in that the air conditioner must be made large as the structure of the compressor increases when it is mounted on the air conditioner.
또한 난방용으로 사용하는 히트펌프의 경우는 실외기의 온도가 영하로 떨어지는 추운 겨울에 운전해야 하므로 액냉매의 유입은 더욱 많아진다. 상기의 문제를 해결하기 위해 어큐물레이터(19) 내에 히터를 장착하는 경우도 있으나, 어큐물레이터(19) 내에 히터를 장착하기 어렵고 원가상승의 요인이 된다. 액냉매가 흡입관(17)을 통해 실린더(6)내로 들어오면 액냉매가 비압축성 유체이므로 압축이 되지 않고 좁은 토출 통로를 통해 일시에 토출되어야 하므로 압축기구부의 손상을 일으켜 압축기의 신뢰성을 저하시키는 문제점이 있다.In addition, in the case of the heat pump used for heating, the temperature of the outdoor unit must be operated in a cold winter when the temperature drops below zero, so the inflow of liquid refrigerant increases. In order to solve the above problem, a heater may be mounted in the accumulator 19, but it is difficult to mount the heater in the accumulator 19, which causes a cost increase. When the liquid refrigerant enters the cylinder 6 through the suction pipe 17, since the liquid refrigerant is an incompressible fluid, it must be discharged temporarily through a narrow discharge passage because it is not compressed, which causes damage to the compression mechanism and lowers the reliability of the compressor. have.
따라서, 본 발명의 목적은 상기와 같은 문제점을 해결하기 위해 안출한 것을, 압축기의 초기운전시 액냉매에 의한 압축실의 과도한 압력 상승을 방지하므로 기동부하를 줄여 압축기의 효율을 향상시킬 수 있고, 토출밸브의 파손 및 상하베어링의 이상마모를 방지하여 신뢰성을 향상시킬 수 있으며, 어큐물레이터의 용량을 줄일 수 있어, 원가를 절감할 수 있고, 실외 온도가 낮은 겨울철에도 안정된 운전이 가능하도록 한 밀폐형 회전식 압축기의 토출장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, it is possible to improve the efficiency of the compressor by reducing the starting load because it prevents excessive pressure rise of the compression chamber by the liquid refrigerant during the initial operation of the compressor, Reliability can be improved by preventing the discharge valve from being damaged and abnormal wear of the upper and lower bearings, and by reducing the accumulator's capacity, it can reduce costs and ensure stable operation even in winter when the outdoor temperature is low. The present invention provides a discharge device for a rotary compressor.
이러한, 본 발명의 목적은 베인의 근처에 위치하여 실린더내의 압축냉매를 토출하는 토출밸브를 구비한 밀폐형 회전식 압축기에 있어서, 상기 베인의 반대편측에 액냉매 토출밸브를 형성함으로써 달성된다.This object of the present invention is achieved by forming a liquid refrigerant discharge valve on the opposite side of the vane in a hermetic rotary compressor having a discharge valve positioned near the vane to discharge compressed refrigerant in the cylinder.
이하, 본 발명에 의한 밀폐형 회전식 압축기의 토출장치를 첨부도면에 도시한 실시예에 따라서 설명한다.Hereinafter, the discharge device of the hermetic rotary compressor according to the present invention will be described according to the embodiment shown in the accompanying drawings.
제3도는 일반적으로 토출밸브를 나타낸 단면도 및 평면도이고, 제4도는 본 발명에 의한 압축기의 압축부를 나타내는 횡단면도이며, 제5도는 일반적인 어큐물레이터의 작용을 나타낸 단면도를 각각 보인 것이다.3 is a cross-sectional view and a plan view generally showing a discharge valve, FIG. 4 is a cross-sectional view showing a compression part of a compressor according to the present invention, and FIG. 5 is a cross-sectional view showing the operation of a general accumulator, respectively.
이에 도시한 바와 같이, 본 발명에 의한 밀폐형 회전식 압축기의 토출장치는 베인(20)의 근처에 위치하여 실린더(6)내의 압축냉매를 토출하는 토출밸브(22)를 구비한 밀폐형 회전식 압축기에 있어서, 상기 베인(20)의 반대편측에 액냉매 토출밸브(31)를 형성한다.As shown in the drawing, the discharge device of the hermetic rotary compressor according to the present invention is a hermetic rotary compressor having a discharge valve 22 which is located near the vane 20 and discharges the compressed refrigerant in the cylinder 6, The liquid refrigerant discharge valve 31 is formed on the opposite side of the vane 20.
상기 액냉매 토출밸브(31)는 상기 베인(20)으로부터 150°에서 120° 사이에 위치한 것을 특징으로 한다.The liquid refrigerant discharge valve 31 is characterized in that located between 150 ° to 120 ° from the vane (20).
이와 같이 형성된 본 발명에 의한 밀폐형 회전식 압축기의 토출장치의 작용효과를 설명하면 다음과 같다.Referring to the effect of the discharge device of the hermetic rotary compressor according to the present invention formed as described above are as follows.
흡입관(17)을 통하여 실린더(6)의 저압부(26)로 흡입된 냉매가스는 롤러(8)의 회전압축에 의해 압축이 되어 베인(20)에 의해 구분되어진 고압부(26)로 밀어내며, 고압부(26)의 고압냉매가스는 밀폐용기(1)내의 토출공간의 압력보다 높은 압력에서만 토출밸브(22)를 열고, 토출공간으로 나갈 수 있다. 일반적으로 제4도와 같이, 상기 롤러(8)가 액냉매 토출밸브(31)를 지날 때 까지는 고압부(26)의 압력이 밀폐용기(1)내의 토출공간의 압력보다 항상 낮게 되어 있어서 상기 액냉매 토출밸브(31)는 열리지 않게 된다.The refrigerant gas sucked into the low pressure portion 26 of the cylinder 6 through the suction pipe 17 is compressed by the rotational compression of the roller 8 and pushed out to the high pressure portion 26 separated by the vane 20. The high pressure refrigerant gas of the high pressure unit 26 may open the discharge valve 22 only at a pressure higher than the pressure of the discharge space in the sealed container 1 and go out to the discharge space. In general, as shown in FIG. 4, the pressure of the high pressure portion 26 is always lower than the pressure of the discharge space in the sealed container 1 until the roller 8 passes the liquid refrigerant discharge valve 31, thereby discharging the liquid refrigerant. The valve 31 is not opened.
그러나, 압축기의 운전초기나, 겨울철 주위 온도가 낮은 경우 증발기(14)에서 증발이 제대로 되지 않은 액냉매가 흡입관(17)을 통하여 저압부(25)로 유입되면 액냉매는 비 압축성 유체이므로, 롤러(8)가 상기 액냉매 토출밸브(31)를 지나기 전에 압력이 급격히 상승하여 고압부(26)의 압력이 밀폐용기(1)내의 토출공간의 압력보다 상승하게 되어, 액냉매토출밸브(31)와 기존의 토출밸브(22)가 동시에 열리게 되어 고압부(26)를 빠져나가므로 압축기의 부하를 줄일 수 있고, 또한 압축기의 신뢰성을 확보할 수가 있다.However, when the initial operation of the compressor or when the ambient temperature is low in winter, when the liquid refrigerant that is not properly evaporated in the evaporator 14 flows into the low pressure portion 25 through the suction pipe 17, the liquid refrigerant is a non-compressible fluid, Before (8) passes the liquid refrigerant discharge valve 31, the pressure rises rapidly, and the pressure of the high pressure portion 26 rises above the pressure of the discharge space in the sealed container 1, so that the liquid refrigerant discharge valve 31 and Since the existing discharge valve 22 is opened at the same time and exits the high pressure part 26, the load of the compressor can be reduced and the reliability of the compressor can be ensured.
액냉매 토출밸브(31)의 위치를 베인(20)을 기준으로 해서 150°에서 210°사이에 설치해야만 액압축시 상기 밸브(31)가 작동하게 되고 정상, 압축시는 동작을 하지 않게 된다.The position of the liquid refrigerant discharge valve 31 should be installed between 150 ° and 210 ° based on the vanes 20 so that the valve 31 operates during liquid compression and does not operate during normal and compression operation.
이와 같이 함으로써, 기존의 냉매의 흐름을 나타내는 제5도와 같은 일반적인 어큐물레이터(19)로도 본 발명의 목적을 달성할 수 있게 된다.By doing in this way, the objective of this invention can be achieved also with the general accumulator 19 like FIG. 5 which shows the flow of a conventional refrigerant | coolant.
이상에서 설명한 바와 같이, 본 발명에 의한 밀폐형 회전식 압축기의 토출장치는 베인의 근처에 위치하여 실린더내의 압축냉매를 토출하는 토출밸브를 구비한 밀폐형 회전식 압축기에 있어서, 상기 베인의 반대편측에 액냉매 토출밸브를 형성하여, 압축기의 초기운전시 액냉매에 의한 압축실의 과도한 압력상승을 방지하므로 기동부하를 줄여 압축기의 효율을 향상시킬 수 있고, 토출밸브의 파손 및 상하베어링의 이상마모를 방지하여 신뢰성을 향상시킬 수 있으며, 어큐물레이터의 용량을 줄일 수 있어, 에어컨은 취부가 용이하며 원가를 절감할 수 있고, 실외 온도가 낮은 겨울철에도 안정된 운전이 가능하도록 한 효과가 있다.As described above, the discharge device of the hermetic rotary compressor according to the present invention is a hermetic rotary compressor having a discharge valve which is located near the vanes and discharges the compressed refrigerant in the cylinder. By forming a valve, it prevents excessive pressure rise in the compression chamber by liquid refrigerant during the initial operation of the compressor, thereby reducing the starting load, improving the efficiency of the compressor, and preventing damage to the discharge valve and abnormal wear of the upper and lower bearings. It is possible to improve the capacity of the accumulator can be reduced, the air conditioner is easy to mount, reduce the cost, and has the effect of enabling stable operation even in winter when the outdoor temperature is low.
