본 발명은 공기조화기의 로터리 압축기에 관한 것으로, 특히 증발기에서 이송되는 저온, 저압의 액상냉매를 가열함으로써, 액상냉매가 압축기의 흡입측으로 유입되는 것을 방지할 수 있는 로터리 압축기 구조에 관한 것이다.The present invention relates to a rotary compressor of an air conditioner, and more particularly, to a rotary compressor structure capable of preventing liquid refrigerant from entering the suction side of a compressor by heating a low-temperature, low-pressure liquid refrigerant that is transferred from an evaporator.

도 1에 도시된 바와 같이, 공기조화기는 냉매가스를 고온·고압으로 압축시키는 압축기(10)와, 압축기(10)에서 이송된 고온·고압의 냉매가스를 방열시켜 점차적으로 액체상태로 상변화시키는 응축기(미도시)와, 응축기에서 액체상태로 상변화되어 이송된 냉매를 저온의 액체 및 기체상태로 감압하는 팽창기구(미도시)와, 팽창기구에서 이송된 저온의 액체 및 기체상태의 냉매를 통과시키면서 증발되어 주변열을 빼앗아 외부온도를 낮은 온도로 유지시키는 동시에 증발된 냉매가스를 다시 압축기(10)로 이송시키도록 하는 증발기(미도시)와, 증발기에서 회수되는 냉매를 액체와 기체로 분리하여 기체냉매만을 압축기(10)로 공급되도록 하는 어큐뮬레이터(20)로 구성되어 있다.As shown in FIG. 1, the air conditioner is configured to gradually change a phase of a refrigerant into a liquid state by dissipating the compressor 10, which compresses the refrigerant gas at high temperature and high pressure, and the high temperature and high pressure refrigerant gas transferred from the compressor 10. A condenser (not shown), an expansion mechanism (not shown) that depressurizes the refrigerant transferred from the condenser into a liquid state to a low temperature liquid and gaseous state, and a low temperature liquid and gaseous refrigerant transferred from the expansion device. An evaporator (not shown) for evaporating and passing ambient heat to keep the external temperature at a low temperature while transferring the evaporated refrigerant gas to the compressor 10 and separating the refrigerant recovered from the evaporator into liquid and gas. It consists of an accumulator 20 to supply only the gas refrigerant to the compressor (10).

한편, 공기조화기에서 어큐뮬레이터(20)는 상기와 같이 증발기로부터 증발된 냉매를 기체와 액체로 분리하여 기체 냉매만을 압축기로 유입되도록 하여 액체 냉매가 압축기(10)로 유입되는 것을 막음으로써 액체냉매의 압축에 의한 압축기(10)의 손상을 방지한다.On the other hand, in the air conditioner, the accumulator 20 separates the refrigerant evaporated from the evaporator into gas and liquid as described above so that only the gas refrigerant is introduced into the compressor, thereby preventing the liquid refrigerant from entering the compressor 10. Prevents damage to the compressor 10 by compression.

따라서, 종래 공기조화기는 액체 냉매가 압축기로 유입되는 것을 방지하기 위해 반드시 어큐뮬레이터를 필요로 하는 단점이 있었다. Therefore, the conventional air conditioner has a disadvantage in that an accumulator is necessary to prevent the liquid refrigerant from flowing into the compressor.

` 본 발명은 상기와 같은 점을 감안하여 안출된 것으로, 종래 어큐뮬레이터가 없더라도 공기조화기가 정상적으로 작동할 수 있도록 하기 위하여 증발기에서 이송되는 저온, 저압의 액체냉매가 압축기의 흡입측으로 유입되는 것을 원천적으로 방지할 수 있는 로터리 압축기 구조를 제공하는데 그 목적이 있다. `The present invention has been devised in view of the above, and prevents the low-temperature, low-pressure liquid refrigerant from the evaporator to be introduced to the suction side of the compressor in order to enable the air conditioner to operate normally even without a conventional accumulator. It is an object of the present invention to provide a rotary compressor structure.

상기와 같은 목적을 달성하기 위하여, 본 발명은 유입된 냉매를 고온고압으로 압축시켜 토출하는 바디 튜브와, 상기 바디 튜브의 일측 내부공간과 연통되게 설치되어 냉매를 상기 바디 튜브 내부로 유입하는 유입관과, 상기 바디 튜브의 타 측 내부공간과 연통되게 설치되어 냉매를 상기 바디 튜브 외부로 토출하는 배출관으로 구성되어진 공기조화기의 로터리 압축기에 있어서, 상기 유입관이 상기 바디 튜브의 외주를 감싸도록 구비되어 상기 압축기의 열에 의해 상기 유입관 내부의 액체냉매가 기화되도록 하여 상기 바디 튜브 내부로 액냉매가 유입되는 것을 방지함과 동시에 압축기의 방열효과도 가져오는 것을 특징으로 한다. In order to achieve the above object, the present invention is the body tube for compressing the discharged refrigerant at a high temperature and high pressure discharge, and installed in communication with the inner space of one side of the body tube inlet tube for introducing the refrigerant into the body tube And a rotary compressor installed in communication with the other inner space of the body tube and configured to discharge the refrigerant to the outside of the body tube, wherein the inlet tube surrounds the outer circumference of the body tube. It is characterized in that the liquid refrigerant in the inlet pipe is vaporized by the heat of the compressor to prevent the liquid refrigerant from flowing into the body tube and at the same time bring about a heat radiation effect of the compressor.

바람직하게는, 상기 유입관에는 필터가 구비되어 1차적으로 액냉매를 걸러내는 것을 특징으로 한다.
Preferably, the inlet pipe is provided with a filter, characterized in that the primary to filter the liquid refrigerant.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 로터리 압축기 구조를 상세하게 설명한다.Hereinafter, a rotary compressor structure according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

도 2는 본 발명에 따른 로터리 압축기 구조를 개략적으로 도시한 도면이다. 2 is a view schematically showing a rotary compressor structure according to the present invention.

도시된 바와 같이, 본 발명은 유입된 냉매를 고온고압으로 압축시켜 토출하는 바디 튜브(110)와, 상기 바디 튜브의 일측 내부공간과 연통되게 설치되어 냉매를 상기 바디 튜브 내부로 유입하는 유입관(120)과, 상기 바디 튜브(110)의 타측 내부공간과 연통되게 설치되어 냉매를 상기 바디 튜브(110) 외부로 토출하는 배출관(130)으로 구성되어진 공기조화기의 로터리 압축기(100)로서, 상기 압축기(100)에서 발생되는 열을 이용하여 상기 압축기(100) 내부로 액냉매가 유입되는 것을 원천적으로 방지할 수 있는 구조이다. As shown, the present invention is the body tube 110 for compressing the discharged refrigerant at a high temperature and high pressure discharge, and installed in communication with the inner space of the one side of the body tube inlet tube for introducing the refrigerant into the body tube ( 120, and the rotary compressor 100 of the air conditioner is installed in communication with the other inner space of the body tube 110, the discharge tube 130 for discharging the refrigerant to the outside of the body tube 110, The heat generated from the compressor 100 is used to prevent the liquid refrigerant from flowing into the compressor 100.

한편, 본 발명의 로터리 압축기 구조를 좀더 상세히 설명하면, 상기 유입관(120)이 상기 바디 튜브(110)의 외주를 감싸도록 구비되어 상기 압축기(100)의 열 에 의해 상기 유입관(120) 내부의 액체냉매가 기화되도록 하여 상기 바디 튜브(110) 내부로 액냉매가 유입되는 것을 방지한다. On the other hand, the rotary compressor structure of the present invention in more detail, the inlet pipe 120 is provided so as to surround the outer periphery of the body tube 110, the inlet pipe 120 by the heat of the compressor 100 By allowing the liquid refrigerant of the vaporization to prevent the liquid refrigerant from flowing into the body tube (110).

동시에, 유입관(120)을 통해 유입되는 저온저압의 냉매가 압축기(100)의 열기를 흡수하면서 기화되기 때문에, 압축기(100)의 방열효과도 가져오게 된다. At the same time, since the low temperature low pressure refrigerant flowing through the inlet pipe 120 is vaporized while absorbing the heat of the compressor 100, the heat radiation effect of the compressor 100 is also brought about.

바람직하게는, 상기 유입관(120)에는 필터(140)가 구비되어 사이클 내부 이물질을 걸러낸다.
Preferably, the inlet pipe 120 is provided with a filter 140 to filter foreign matter in the cycle.

이러한 구성의 본 발명에 따른 공기조화기의 로터리 압축기 구조를 상세히 설명하면 다음과 같다. The rotary compressor structure of the air conditioner according to the present invention having such a configuration will be described in detail as follows.

즉, 압축기(100)는 증발기로부터 흡입된 냉매를 유입관(120)을 통하여 바디 튜브(110) 내부로 유입시켜 상기 유입된 냉매를 고온고압으로 압축하여 배출관(130)을 통해 외부로 토출한다. That is, the compressor 100 introduces the refrigerant sucked from the evaporator into the body tube 110 through the inlet pipe 120, compresses the introduced refrigerant at high temperature and high pressure, and discharges the refrigerant to the outside through the discharge pipe 130.

한편, 종래 어큐뮬레이터가 없는 상기와 같은 압축기(100)는 외기온도가 현저히 낮은 경우, 유입관(120)을 통해 압축기내로 액체냉매가 유입될 가능성이 높아지게 된다. 따라서, 액체냉매의 압축에 의한 압축기(100)의 손상 가능성도 높아지게 된다. On the other hand, in the compressor 100 as described above without the accumulator, when the outside air temperature is significantly low, the possibility of liquid refrigerant flowing into the compressor through the inlet pipe 120 is increased. Therefore, the possibility of damage to the compressor 100 due to the compression of the liquid refrigerant also increases.

이때, 본 발명은 유입관(120)이 바디 튜브(110) 외주를 감싸고 있기 때문에 압축기(100)에서 발생되는 열기에 의해 유입관(120) 내에 포함된 액체냉매를 직접 가열하여 기화시킴으로써, 기체상태의 냉매만을 상기 유입관(120)을 통해 압축기(100)내로 유입된다. At this time, in the present invention, since the inlet pipe 120 surrounds the outer circumference of the body tube 110, a gaseous state is produced by directly heating and vaporizing the liquid refrigerant contained in the inlet pipe 120 by the heat generated from the compressor 100. Only the refrigerant flows into the compressor 100 through the inlet pipe 120.                     

따라서, 상기 유입관(120)을 압축기(100)의 열기를 이용하여 가열함으로써, 압축기(100)측으로 액체냉매의 유입을 원천적으로 방지하고, 특히 저온난방시 고온의 기체냉매를 공급함으로써 압축기(100)의 부하를 덜어주게 된다. Therefore, the inlet pipe 120 is heated by using the heat of the compressor 100 to prevent the inflow of the liquid refrigerant to the compressor 100, and in particular, by supplying a high-temperature gas refrigerant during low temperature heating of the compressor 100 Will reduce the load on the

이와 동시에, 유입관(120) 내부의 액체냉매의 기화로 인해 압축기(100)의 방열효과도 기대할 수 있어 압축기(100)의 효율이 크게 향상된다. At the same time, due to the vaporization of the liquid refrigerant in the inlet pipe 120, the heat radiation effect of the compressor 100 can also be expected, so that the efficiency of the compressor 100 is greatly improved.

상기된 바와 같은 본 발명은 종래 어큐뮬레이터가 없더라도 공기조화기가 정상적으로 작동할 수 있도록 하기 위하여 증발기에서 이송되는 저온, 저압의 액체냉매가 압축기의 흡입측으로 유입되는 것을 원천적으로 방지할 수 있는 효과도 있다. The present invention as described above has the effect of preventing the low-temperature, low-pressure liquid refrigerant from the evaporator to be introduced to the suction side of the compressor in order to enable the air conditioner to operate normally even without a conventional accumulator.

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may vary without departing from the spirit of the technical idea of the present invention described in the claims below.
