미설명부호(141)은 압축기(103)를 고정시키도록 된 고정부를 나타낸다.Reference numeral 141 denotes a fixing portion to fix the compressor 103.

이와 같이 구성된 에어컨은 도시되지 않은 조작주의 조작에 의해 전원이 인가되면 압축기(103)가 작동하여 냉매를 고온고압으로 압축하고, 상기 고온고압으로 압축된 냉매는 실외측열교환기(105)로 유입되어 상온고압의 액냉매로 상변화된다.When the air conditioner configured as described above is powered by an operation not shown, the compressor 103 operates to compress the refrigerant to high temperature and high pressure, and the refrigerant compressed to the high temperature and high pressure flows into the outdoor side heat exchanger 105. Phase change with liquid refrigerant at room temperature and high pressure.

상기 실외측열교환기(105)를 통과한 상오고압의 액냉매는 모세관(107)을 통과하면서 감압된 후, 실내측열교환기(109)로 유입되고, 상기 실내측열교환기(109)에 유입된 냉매는 저온저압의 냉매가스로 기화되어 다시 압축기(103)로 유입되는 냉매사이클을 반복 수행하게 된다.The liquid refrigerant of ordinary high pressure passing through the outdoor side heat exchanger (105) is decompressed while passing through the capillary tube (107), and then flows into the indoor side heat exchanger (109) and flows into the indoor side heat exchanger (109). The refrigerant is repeatedly vaporized into the refrigerant gas of low temperature and low pressure and flowed back into the compressor 103.

이때, 상기 압축기(103)가 작동됨과 동시에 모터(133)가 작동함에 따라 회전축부재(133a,133b)와 블로워팬(117) 및 프로펠러팬(121)이 회전하여 실내공기 및 실내공기를 실내측열교환기(109) 및 실외측열교환기(105)로 블로잉하게 된다.At this time, as the compressor 103 is operated and the motor 133 is operated, the rotary shaft members 133a and 133b, the blower fan 117, and the propeller fan 121 rotate to exchange indoor air and indoor air. Blower 109 and the outdoor side heat exchanger 105.

상기 블로워팬(117)은 회전에 의해 실내공기가 흡입그릴부재(129)의 흡입구멍(129a)을 통해 흡입되고, 이렇게 흡입된 공기는 필터부재(131)를 통해 이물질이 필터링된 후, 상기 실내측열교환기(109)를 통해 냉풍으로 열교환되며, 상기 실내측열교환기(109)에서 열교환된 냉풍은 실선화살표를 따라 블로워팬(117)쪽으로 유입되어 덕트부재(113)의 안내를 받아 토출구(135)를 통해 토출되어 냉방을 행하게 된다.The blower fan 117 is rotated by the indoor air is sucked through the suction hole 129a of the suction grill member 129, and the sucked air is filtered through the filter member 131, and then indoors. Heat exchanged by cold air through the side heat exchanger (109), the cold air heat exchanged in the indoor heat exchanger (109) is introduced into the blower fan 117 along the solid arrow is guided by the duct member 113 discharge port 135 It is discharged through) to perform cooling.

그리고, 상기 프로펠러팬(121)이 회전됨에 따라 실외공기가 점선화살표를 따라 덮개부재(125)의 실외공기흡입구(125a)를 통해 흡입되고, 이렇게 흡입된 실외공기는 압축기(103)와 모터(133) 및 실외측열교환기(105)의 외부를 지나면서 압축기(103) 및 모터(133)를 냉각시킴과 동시에, 상기 실외측열교환기(105)내에 흐르는 냉매를 냉각시킨 후 더워지게 되어 후면판(127)의 배출구(127a)를 통해 외부로 배출된다.As the propeller fan 121 is rotated, outdoor air is sucked through the outdoor air inlet 125a of the cover member 125 along the dotted arrow, and the outdoor air sucked in this way is the compressor 103 and the motor 133. Cooling the compressor 103 and the motor 133 while passing through the outside of the outdoor side heat exchanger 105 and cooling the refrigerant flowing in the outdoor side heat exchanger 105 to become hot. It is discharged to the outside through the outlet 127a of the 127.

여기서, 상기 모세관(107)을 통과하면서 감압된 냉매를 받아 주위의 열을 흡수하여 저온저압의 냉매로 기화시키도록 된 증발기(1)와 압축기(2)사이의 저압측연결관(3)에는 제3도에 도시된 바와 같이, 저압측의 냉매주입용 튜브(4)가 배설되되, 상기 압축기(3)에 의해 압축된 고온고압의 냉매를 받아 고압상온의 액상냉매로 응축시키도록 된 응축기(5)와 팽창변(6)사이의 고압측연결관(7)에는 고압측의 냉매주입용 튜브(8)가 배설되어 있는 바, 이러한 종래의 냉매주입용 튜브(4,8)에는 제5도에 도시된 바와 같이, 연결관(3,7)의 소정우치에는 냉매가스를 주입시키기 위해 사용하도록 된 원형관모양의 냉매주입용 튜브(4,8)의 일측끝단부가 용접으로 고착되고, 이 냉매주입용 튜브(4,8)의 반대측 끝단부에는 상기 냉매주입용 튜브(4,8)의 직경보다 작은 직경을 갖춘 니플연결관(9)이 용접으로 고착되어 있다.Here, the low pressure side connecting pipe (3) between the evaporator (1) and the compressor (2), which receives the reduced pressure while passing through the capillary tube (107), absorbs the surrounding heat and vaporizes it into a low temperature low pressure refrigerant. As shown in FIG. 3, a low pressure refrigerant injection tube 4 is disposed, and the condenser 5 is configured to receive a high temperature and high pressure refrigerant compressed by the compressor 3 and condense it into a liquid refrigerant at high pressure and room temperature. And a high pressure side refrigerant injection tube 8 are disposed in the high pressure side connecting tube 7 between the expansion valve 6 and the expansion valve 6, and these conventional refrigerant injection tubes 4 and 8 are shown in FIG. As shown in the drawing, one end of the circular tube-shaped refrigerant injection tubes 4 and 8, which is used to inject refrigerant gas, is fixed to the predetermined grooves of the connection pipes 3 and 7, by welding. The opposite end of the tube (4,8) has a diameter smaller than the diameter of the refrigerant injection tube (4,8) Connectors (9) are fixed by welding.

따라서 니플연결관(9)의 끝단부에 냉매가스를 주입시키기 위한 장치를 밀착시킨 후 냉매가스를 주입시키게 되면, 냉매가스가 니플연결관(9) 및 냉매주입용 튜브(4,8)를 통과해 저압측·고압측연결관(3,7)을 매개로 에어컨의 내부로 충진되는 바, 이때 냉매가스가 주입되면 냉매주입용 튜브(4,8)의 소정부위를 절단부재로 잘라낸 다음 에어컨에 주입된 냉매가스가 누설되지 않도록 완전히 밀봉시킴으로써 냉매가스의 주입이 종료되게 된다.Therefore, when the device for injecting the refrigerant gas to the end of the nipple connecting tube 9 is in close contact with the refrigerant gas, the refrigerant gas passes through the nipple connecting tube 9 and the refrigerant injection tubes 4 and 8. The low pressure side and high pressure side connection pipes 3 and 7 are filled into the air conditioner. When refrigerant gas is injected, predetermined portions of the refrigerant injection tubes 4 and 8 are cut out with a cutting member, and then The injection of the refrigerant gas is completed by completely sealing the injected refrigerant gas so as not to leak.

그러나 이와 같은 구조로 배설된 종래의 냉매주입용 튜브(4,8)에 의하면, 에어컨의 사용중 시간이 경과됨에 따라 제품(에어컨)의 내부에 충진되었던 냉매가스가 모두 소진되었을 경우나 또는 에어컨에 사용되는 각종 장치등의 불량으로 에어컨의 내부에 냉매가스를 재주입시켜야 하는 경우 저·고압측연결관(3,7)에 용접된 냉매주입용 튜브(4,8)을 완전히 떼어내고 새로운 튜브로 교체한 후 니플연결관(9)을 냉매주입용 튜브(4,8)에 용접결합시킴과 더불어 이 냉매주입용 튜브(4,8)를 저·고압측연결관(3,7)에 용접결합해야 하므로, 작업공정이 늘어남에 따라 작업자의 작업능률이 저하될 뿐만 아니라 냉매가스의 재주입시마다 냉매주입용 튜브(4,8)를 새것으로 교체해야 하므로 냉매주입용 튜브(4,8)가 과다하게 소모되는 문제점이 있었다.However, according to the conventional refrigerant injection tubes (4, 8) arranged in such a structure, when the refrigerant gas filled in the interior of the product (air conditioner) as the time elapsed during use of the air conditioner is used or used in the air conditioner If it is necessary to re-inject refrigerant gas into the inside of the air conditioner due to various devices, etc., remove the refrigerant injection tubes (4, 8) welded to the low and high pressure connection pipes (3, 7) completely and replace them with new tubes. Then, the nipple connector (9) is welded to the refrigerant injection tubes (4, 8) and the refrigerant injection tubes (4,8) are welded to the low and high pressure side connection tubes (3,7). Therefore, as the work process increases, not only the worker's work efficiency decreases, but also the refrigerant injection tubes 4 and 8 need to be replaced with new ones every time the refrigerant gas is re-injected. There was a problem that was exhausted.

또한, 냉매가스의 재주입시 저·고압측연결관에 용접된 냉매주입용 튜브(4,8)를 떼어내기 위해서는 제5도에 도시된 A부의 용접부에 재용접을 실시해야 하는 바, 이때 상기 저·고압측연결관(3,7)의 온도가 상승되어 압축기오일이 타버리게 됨은 물론, 새로운 냉매주입용 튜브(4,8)의 용접시 저·고압측연결관(3,7)의 내부로 깊게 삽입되어 에어컨의 성능 및 신뢰성이 저하되는 문제점이 있었다.In addition, in order to remove the refrigerant injection tubes 4 and 8 welded to the low and high pressure side connection pipes during the re-injection of the refrigerant gas, it is necessary to re-weld the welding part of the A part shown in FIG. Compressor oil burns as the temperature of the high pressure side connection pipes 3 and 7 rises, and into the inside of the low and high pressure side connection pipes 3 and 7 when the new refrigerant injection tubes 4 and 8 are welded. Inserted deeply, there was a problem that the performance and reliability of the air conditioner is lowered.

이에 본 고안은 상기와 같은 모든 문제점들을 해소하기 위해 안출된 것으로, 냉매주입용 튜브의 소정위치에 절단용홈을 형성시켜 에어컨의 내부로 냉매가스의 재주입시 새로운 냉매주입용 튜브를 사용하지 않고 기존의 냉매주입용 튜브를 그대로 사용함으로 인해 작업공정을 단순화시켜 작업자의 작업능률을 향상시키고, 냉매주입용 튜브의 과다소모를 방지함과 더불어 에어컨의 성능저하 및 신뢰성이 저하되는 것을 방지할 수 있도록 된 종래의 창문형 에어컨의 냉매주입용 튜브를 제공함에 그 목적이 있다.The present invention has been devised to solve all the problems described above, by forming a cutting groove at a predetermined position of the refrigerant injection tube to re-inject the refrigerant gas into the interior of the air conditioner without using a new refrigerant injection tube By using the refrigerant injection tube as it is, the work process is simplified to improve the worker's work efficiency, prevent excessive consumption of the refrigerant injection tube, and prevent the deterioration of air conditioner performance and reliability. The purpose is to provide a tube for refrigerant injection of the window air conditioner of the.
