도 1 내지 도 3 에 나타낸 바와 같이, 압력 감지부(10)는 에어콘의 냉매 순환라인(5)에 설치하고, 냉매 순환라인(5)측에 금속 다이어프램(11)을 설치하며, 금속 다이어프램(11)의 후측에 압력감지 스위치(14)를 설치하되, 압력감지 스위치(14)의 접점(12a, 12b) 사이에 스프링(13)를 설치하여 금속 다이어프램(11)의 작동시 스프링(13)을 압축시켜 접점(12a, 12b)을 도통시키게 한다.1 to 3, the pressure sensing unit 10 is installed in the refrigerant circulation line 5 of the air conditioner, the metal diaphragm 11 is installed on the refrigerant circulation line 5 side, and the metal diaphragm 11 is provided. The pressure sensing switch 14 is installed on the rear side of the side, but the spring 13 is installed between the contacts 12a and 12b of the pressure sensing switch 14 to compress the spring 13 when the metal diaphragm 11 operates. To make the contacts 12a and 12b conduct.

구동부(30)는 상기 압력 감지부(10)의 압력 스위치(14)와 접속된 릴레이(31)에 모터(32)를 접속하고, 모터(32)의 회전축에 피니언 기어(33)를 부착하며, 모터(32)에 위치 감지센서(34)를 구비한다.The driving unit 30 connects the motor 32 to the relay 31 connected to the pressure switch 14 of the pressure sensing unit 10, and attaches the pinion gear 33 to the rotation shaft of the motor 32. The motor 32 is provided with a position sensor 34.

냉매 배출부(20)는 냉매 순환라인(5)에 차지밸브(21)를 설치하고, 차지밸브(21)의 냉매통로(22)에 피스톤(23)의 로드를 삽입시키되, 피스톤(23)의 상단에 냉매통로(22) 개폐용 밸브(25)를 결합시키고, 피스톤(23)의 상측에 스프링(26)을 설치시켜 항상 피스톤(23)이 하측으로 내려와 피스톤(23) 로드의 밸브(22)가 냉매통로(22)를 차단시키도록 한다.The coolant discharge part 20 installs a charge valve 21 in the coolant circulation line 5 and inserts a rod of the piston 23 into the coolant passage 22 of the charge valve 21, Refrigerant passage 22 opening and closing valve 25 is coupled to the upper end, and a spring 26 is installed on the upper side of the piston 23 so that the piston 23 always descends to the lower side of the valve 22 of the piston 23 rod. To block the refrigerant passage 22.

또한 상기 피스톤(23)의 저면 중앙에 하향으로 로드(24)를 부착하고, 로드(24)의 하단에 턴버클(27)를 결합하되, 턴버클(27)이 구동부(30)의 위치 감지센서(34)와 대응되게 형성한다.In addition, the rod 24 is attached downward to the center of the bottom surface of the piston 23, and the turnbuckle 27 is coupled to the lower end of the rod 24, but the turnbuckle 27 is a position sensor 34 of the driving unit 30. ) To correspond to.

또한 상기 턴버클(27)의 하측에 로드(28)를 결합하고, 로드(28)의 하측에 구동부(30)의 모터 회전축에 결합된 피니언 기어(33)와 치차결합시키는 랙기어(29)를 부착한다.In addition, the rod 28 is coupled to the lower side of the turnbuckle 27, and the rack gear 29 for gear-coupling with the pinion gear 33 coupled to the motor rotation shaft of the drive unit 30 is attached to the lower side of the rod 28. do.

이러한 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention is as follows.

생매순환라인(5)에 냉매 과충전으로 이상 압력이 발생하면, 압력 감지부(10)의 금속 다이어프램(11)을 압압하게 되므로 금속 다이어프램(11)이 스프링을 누르게 되어 압력감지스위치(14)의 접점(12a,12b)를 통전시켜 릴레이(31)을 온시켜 모터를 구동시킨다.When abnormal pressure occurs due to refrigerant overcharging in the live circulation line 5, the metal diaphragm 11 of the pressure sensing unit 10 is pressed, so that the metal diaphragm 11 presses a spring to contact the pressure sensing switch 14. By energizing the 12a and 12b, the relay 31 is turned on to drive the motor.

따라서 모터(32)의 구동으로 피니언 기어(33)가 회전하게 되고, 이로 인하여 피니언 기어(33)와 치차결합된 랙기어(29)가 상측으로 직선운동하여 로드(28)와 턴버클(27) 및 로드(24)를 통하여 스프링(26)으로 탄력설치된 피스톤(23)를 상측으로 밀어 피스톤(23)의 로드가 차지밸브(21)의 냉매통로(22)를 벗어나게 됨으로써, 냉매통로(22)가 열려 냉매 순환라인(5)의 냉매를 외부로 배출시킨다.Accordingly, the pinion gear 33 is rotated by the driving of the motor 32, and thus the rack gear 29 geared to the pinion gear 33 linearly moves upwards, such that the rod 28 and the turnbuckle 27 and The piston 23 elastically installed by the spring 26 is pushed upward through the rod 24 so that the rod of the piston 23 leaves the refrigerant passage 22 of the charge valve 21, thereby opening the refrigerant passage 22. The refrigerant of the refrigerant circulation line 5 is discharged to the outside.

또한, 냉매 순환라인(5)의 냉매가 적정수준으로 유지되면 금속 다이어프램(11)에 가해진 압력이 줄어들어 스프링(13)의 탄성에 의하여 압력감지 스위치(14)의 접점(12a, 12b)을 단락시켜 모터(32)에 가해진 전원을 차단한다.In addition, when the refrigerant in the refrigerant circulation line 5 is maintained at an appropriate level, the pressure applied to the metal diaphragm 11 is reduced to short the contacts 12a and 12b of the pressure sensing switch 14 by the elasticity of the spring 13. The power applied to the motor 32 is cut off.

이때 위치 감지센서(34)에 의하여 모터(32)로 역동작시켜 윈위치시킨다.At this time, by the position sensor 34 to reverse the operation of the motor 32 to the win position.

따라서 차지밸브(21)의 피스톤(23) 상측에 설치된 스프링(26)의 탄성에 의하여 피스톤(23)이 하측으로 내려오게 되며, 이로 인하여 피스톤(23)의 로드도 내려와 피스톤(23)의 로드(24) 상단에 부착된 밸브(25)가 차지밸브(21)의 냉매통로922)를 차단하여 더 이상의 냉매 배출을 방지한다.Therefore, the piston 23 is lowered due to the elasticity of the spring 26 installed above the piston 23 of the charge valve 21. As a result, the rod of the piston 23 is also lowered and thus the rod of the piston 23 ( 24) The valve 25 attached to the top blocks the refrigerant passage 922 of the charge valve 21 to prevent further refrigerant discharge.

이상에서 살펴본 바와 같이, 본 발명은 에어콘의 냉매 순환라인에 냉매가 과충전된 경우 이를 즉시 외부로 배출시켜 적정량의 냉매로 냉각 사이클을 운전함으로써, 냉각 사이클의 각부 기기에 무리가 발생하여 기기가 손상되는 것을 방지하고, 냉각효율을 극대화시킬 수 있는 것이다.As described above, in the present invention, when the refrigerant is overcharged in the refrigerant circulation line of the air conditioner, it is immediately discharged to the outside to operate the cooling cycle with the appropriate amount of refrigerant, thereby causing a damage to the equipment of each part of the cooling cycle. It can prevent and maximize the cooling efficiency.
