본 발명은 음극선관 커플러조립체의 냉매유출감지장치에 관한 것으로, 보다 상세하게는 커플러조립체에서 유출되는 냉매를 저장하는 냉매저장케이스 내부에 냉매유출감지센서를 구비하여 유출되는 냉매를 감지시 외부로 알리기 위한 음극선관 커플러조립체의 냉매유출감지장치에 관한 것이다. The present invention relates to a refrigerant leak detection apparatus of a cathode ray tube coupler assembly, and more particularly, to provide a refrigerant leak detection sensor inside the refrigerant storage case for storing the refrigerant flowing out of the coupler assembly to notify the outside when the refrigerant leaks. The present invention relates to a refrigerant leak detection apparatus for a cathode ray tube coupler assembly.

일반적으로 음극선관 프로젝션 텔레비전(cathode ray tube projection television)을 이용한 투사형 표시장치는 음극선관(Cathode Ray Tube; "CRT"라고 함)에 의해 결상된 화상을 스크린에 확대 표시하는 표시장치이다.In general, a projection display device using a cathode ray tube projection television is a display device that enlarges and displays an image formed by a cathode ray tube ("CRT") on a screen.

음극선관 프로젝션 텔레비전은 화상을 표시하기 위한 음극선관과, 음극선관으로부터 화상을 스크린으로 전반사 시키기 위한 반사미러와, 음극선관에 표시된 화상을 반사미러 쪽으로 안내하기 위한 투사렌즈를 구비한다.The cathode ray tube projection television includes a cathode ray tube for displaying an image, a reflection mirror for total reflection of the image from the cathode ray tube to the screen, and a projection lens for guiding the image displayed on the cathode ray tube toward the reflection mirror.

따라서, 시청자는 음극선관 프로젝션 텔레비전으로부터 보통 플라스틱 재질로 이루어진 스크린에 확대되어 표시되는 화상을 보게 된다.Thus, the viewer sees an image displayed enlarged on a screen usually made of plastic material from the cathode ray tube projection television.

음극선관은 통상 7인치 또는 9인치 크기가 사용되며, 음극선관에 맺혀지는 유효 화상의 크기는 4인치에서 6인치 정도로 된다.Cathode ray tubes are usually 7 inches or 9 inches in size, and the effective image formed on the cathode ray tubes is about 4 inches to 6 inches.

음극선관은 냉각 및 렌즈의 역할을 위해 수냉방식의 구조를 갖는 커플러(coupler)에 의해 일체화된다.The cathode ray tube is integrated by a coupler having a water cooling structure for cooling and acting as a lens.

그리고, 상기 음극선관 커플러조립체는 음극선관이 커플러 하우징에 장착되고, 커플러 하우징의 타측에 고정부재에 의해 렌즈가 설치되며, 커플러 하우징 내측에 음극선관으로부터 발생되는 열을 냉각시키기 위한 냉매가 봉입되고, 커플러 하우징의 일측에 냉매의 열팽창에 따른 압력을 조절하는 냉매 압력조절부재가 브라켓에 의해 설치된다.The cathode ray tube coupler assembly includes a cathode ray tube mounted on the coupler housing, a lens installed on the other side of the coupler housing by a fixing member, and a refrigerant for sealing heat generated from the cathode ray tube inside the coupler housing. One side of the coupler housing is provided with a refrigerant pressure regulating member for adjusting the pressure according to the thermal expansion of the refrigerant by the bracket.

이때, 온도의 변환에 따른 냉매의 팽창 및 압축에 따라 냉매 압력조절부재가 신축이 됨으로써 냉매(6)의 압력을 조절한다.At this time, the refrigerant pressure regulating member is stretched in accordance with the expansion and compression of the refrigerant according to the change of temperature to adjust the pressure of the refrigerant 6.

그런데, 상기 압력조절부재가 시간이 지남에 따라 노화되고 재료 내부의 피로 증가로 균열이 발생하며 이를 통해 냉매가 유출이 된다.However, the pressure regulating member ages with time and cracks occur due to increased fatigue inside the material, through which the refrigerant flows out.

그래서, 상기 압력조절부재 외측에는 냉매저장탱크가 구비된다.Thus, a refrigerant storage tank is provided outside the pressure regulating member.

도 1에 도시된 바와 같이, 종래의 커플러조립체(1)는 음극선관(2)이 커플러 하우징(3)에 홀더(9)로 하여 장착되고, 커플러 하우징(3)의 타측에 고정부재(4)에 의해 렌즈(5)가 설치되며, 커플러 하우징(3) 내측에 음극선관(2)으로부터 발생되는 열을 냉각시키기 위한 냉매(6)가 봉입되고, 커플러 하우징(3)의 일측에 냉매(6)의 열팽창에 따른 압력을 조절하는 냉매 압력조절부재(7)가 브라켓(8)에 의해 설치된다.As shown in FIG. 1, the conventional coupler assembly 1 has a cathode ray tube 2 mounted on the coupler housing 3 as a holder 9, and the fixing member 4 on the other side of the coupler housing 3. The lens 5 is installed, the refrigerant 6 for cooling the heat generated from the cathode ray tube 2 inside the coupler housing 3 is sealed, and the refrigerant 6 on one side of the coupler housing 3. The refrigerant pressure regulating member 7 for adjusting the pressure due to thermal expansion of the bracket 8 is installed by the bracket 8.

상기 냉매(6)는 자연대류와 전도로써 음극선관(2)의 형광면으로부터 발생된 열을 방열하며, 무색 투명한 유체로 형성됨으로써 그 자체로서 하나의 렌즈 역할을 하게 된다.The refrigerant 6 dissipates heat generated from the fluorescent surface of the cathode ray tube 2 by natural convection and conduction, and serves as a lens by itself as formed of a colorless transparent fluid.

또한, 상기 압력조절부재(7)를 통하여 유출되는 냉매를 저장할 수 있도록 냉매저장케이스(10)가 설치된다.In addition, the refrigerant storage case 10 is installed to store the refrigerant flowing out through the pressure control member (7).

그러나, 종래의 커플러조립체는 압력조절부재를 통해 유출되는 냉매를 별도로 저장하기 위해 냉매저장케이스를 별도로 부착하나, 그 내부에 저장되는 냉매의 양을 확인할 수 없어서 지속적인 냉매의 유출로 인해 커플러 하우징 내부에서 냉각작용을 하지 못함과 아울러 과열에 의한 오작동을 발생하게 되는 문제점이 있었다.However, in the conventional coupler assembly, the refrigerant storage case is separately attached to separately store the refrigerant flowing out through the pressure regulating member, but the amount of the refrigerant stored therein cannot be confirmed, so that the refrigerant flows in the coupler housing due to the continuous flow of the refrigerant. There was a problem that the malfunction due to overheating as well as not cooling.

본 발명은 상기한 종래 기술의 문제점을 해결하고자 제안된 것으로서, 커플러조립체의 일측부에 장착된 냉매저장케이스 내부에 냉매유출감지센서를 고정 부착하여 냉매저장케이스 내측벽을 따라 흐르는 냉매 및 일정 수위까지 저장된 냉매를 감지하여 외부로 냉매의 유출을 알림으로써 조속한 단순 수리를 통해 기기의 단락이나 오작동 및 텔레비전의 화재 발생 등의 크나큰 피해를 방지하고자 한 음극선관 커플러조립체의 냉매유출감지장치를 제공함을 그 목적으로 한다. The present invention has been proposed to solve the above problems of the prior art, by fixing a refrigerant leakage sensor inside the refrigerant storage case mounted on one side of the coupler assembly to the refrigerant flowing along the inner wall of the refrigerant storage case and up to a certain level The purpose of the present invention is to provide a refrigerant leak detection device of a cathode ray tube coupler assembly that detects stored refrigerant and notifies refrigerant to the outside to prevent significant damage such as a short circuit or malfunction of a device or a fire of a television through quick and simple repair. It is done.

상기한 목적을 달성하기 위한 본 발명에 따른 음극선관 커플러조립체의 냉매유출감지장치는 커플러 하우징의 내측에 봉입된 냉매의 열팽창에 따른 압력을 조절하는 냉매 압력조절부재를 구비하며, 상기 압력조절부재의 하부에 냉매저장케이스를 구비하여 유출되는 냉매를 저장하는 음극선관의 커플러조립체에 있어서, 상기 냉매저장케이스의 내부에 고정 부착되어 내측벽을 따라 흘러 저장되는 냉매를 감지하는 냉매유출감지센서와, 상기 냉매유출감지센서의 센싱에 의해 냉매의 유출을 외부로 알리는 냉매유출알림부와, 상기 냉매유출감지센서의 센싱에 의해 냉매유출알림부를 제어하며, 냉매유출알림부의 작동 후 텔레비전의 전원스위치를 오프시키도록 제어하는 제어부로 이루어짐을 특징으로 한다.

도 2에 도시된 바와 같이, 본 발명의 일실시에 따른 커플러조립체(41)는 음극선관(42)을 커플러 하우징(43)과 홀더(49)를 매개로 하여 결합하고, 커플러 하우징(43)의 타측에 고정부재(44)로써 렌즈(45)를 설치하며, 커플러 하우징(43) 내측에 음극선관(42)으로부터 발생되는 열을 냉각시키기 위한 냉매(46)를 주입한다.As shown in FIG. 2, the coupler assembly 41 according to one embodiment of the present invention couples the cathode ray tube 42 through the coupler housing 43 and the holder 49, and the coupler housing 43 of the coupler housing 43. The lens 45 is installed as the fixing member 44 on the other side, and the coolant 46 is injected into the coupler housing 43 to cool the heat generated from the cathode ray tube 42.

그리고, 상기 커플러 하우징(43)은 일측에 냉매(46)의 열팽창에 따른 압력을 조절하는 냉매 압력조절부재(47)를 브라켓(48)으로써 고정 설치한다.In addition, the coupler housing 43 is fixedly installed on one side with a bracket 48 to the refrigerant pressure regulating member 47 for adjusting the pressure according to the thermal expansion of the refrigerant 46.

또한, 상기 냉매 압력조절부재(47)의 외측에는 외부로 유출되는 냉매(46)를 저장하기 위해 냉매저장케이스(50)를 고정 설치한다.In addition, the refrigerant storage case 50 is fixedly installed on the outside of the refrigerant pressure regulating member 47 to store the refrigerant 46 flowing out.

상기 냉매저장케이스(50)는, 공지된 것과 같이, 커플러 하우징(43)에 고정 결합된다.The refrigerant storage case 50, as is known, is fixedly coupled to the coupler housing 43.

한편, 상기 냉매저장케이스(50)는 내부에 냉매유출감지센서(60)를 구비한다.On the other hand, the refrigerant storage case 50 is provided with a refrigerant leakage detection sensor 60 therein.

상기 냉매유출감지센서(60)는 통상적인 유량감지센서로 하고, 커플러 하우징(43) 내부의 냉매(46)가 냉매 압력조절부재(47)의 가장자리 틈새로 새어 나와 냉매저장케이스(50)로 유출되는 것을 센싱(sensing)하기 위해 구비된다.The refrigerant flow detection sensor 60 is a conventional flow rate detection sensor, and the refrigerant 46 inside the coupler housing 43 leaks into the edge gap of the refrigerant pressure regulating member 47 and flows out into the refrigerant storage case 50. It is provided for sensing what is to be.

그래서, 상기 냉매유출감지센서(60)는 냉매(46)가 유출되어 흐르는 냉매저장케이스(50) 내측벽에 고정 부착된다.Thus, the coolant outflow detection sensor 60 is fixedly attached to the inner wall of the coolant storage case 50 in which the coolant 46 flows out.

이때, 상기 냉매유출감지센서(60)는 냉매저장케이스(50) 내측벽에 일부 삽입되게 설치될 수도 있고, 스크류에 의해 냉매저장케이스(50) 내측벽과 체결되어 고정 설치될 수도 있다.In this case, the coolant outflow detection sensor 60 may be installed to be partially inserted into the inner wall of the coolant storage case 50, or may be fastened and fixed to the inner wall of the coolant storage case 50 by a screw.

또한, 상기 냉매유출감지센서(60)는 냉매저장케이스(50) 내부 바닥면에 인접되게 고정 설치되어 냉매저장케이스(50) 내부에 소량의 냉매(46) 저장시 이를 센싱하도록 한다.In addition, the coolant outflow detection sensor 60 is fixedly installed adjacent to the bottom surface of the coolant storage case 50 to sense the small amount of coolant 46 in the coolant storage case 50.

한편, 도 3에 도시된 바와 같이, 상기 냉매유출감지센서(60)가 유출되는 냉매(46)와 접하며 센싱되면, 이의 신호를 제어부(90)로 전송한다.Meanwhile, as illustrated in FIG. 3, when the refrigerant leak detection sensor 60 is in contact with the refrigerant 46 flowing out, the signal is transmitted to the controller 90.

그리고, 상기 제어부(90)는 냉매유출감지센서(60)의 신호를 받아 텔레비전의 메인전원을 단속하는 전원스위치(80)를 오프(OFF)시키도록 제어한다. In addition, the control unit 90 controls to turn off the power switch 80 for controlling the main power of the television in response to the signal of the refrigerant leakage detection sensor 60.

이때, 상기 전원스위치(80)는, 공지된 바와 같이, 텔레비전의 구동시 소정 비축된 대기전력으로 전원을 오프시킨다.At this time, the power switch 80, as is known, turns off the power to a predetermined reserve standby power when driving the television.

그리고, 상기 대기전력은 냉매유출알림부(70)에도 공급된다.The standby power is also supplied to the refrigerant discharge notification unit 70.

상기 냉매유출알림부(70)는 임의의 음을 출력하는 통상적인 텔레비전의 스피커일 수도 있고, 가장 바람직하게, 시청자로 하여금 육안으로 확인할 수 있는 알림문구를 디스플레이(display) 하는 텔레비전의 모니터로 한다.The coolant outflow notification unit 70 may be a speaker of a conventional television that outputs arbitrary sound, and most preferably, a monitor of a television that displays a notice text that the viewer can visually check.

즉, 상기 제어부(90)가 냉매유출감지센서(60)의 센싱으로 전원스위치(80)를 오프시키도록 제어하면서 냉매유출알림부(70)를 동시에 제어하면, 대기전원의 공급으로 전원스위치(80)의 작동과 동시에 텔레비전의 모니터에 알림문구를 디스플레이하는 냉매유출알림부(70)가 일시적으로 작동한다.That is, when the control unit 90 controls the refrigerant discharge notification unit 70 at the same time while controlling the control unit 90 to turn off the power switch 80 by sensing the refrigerant flow detection sensor 60, the power switch 80 by the supply of standby power. At the same time as the operation of the) coolant outflow notification unit 70 for displaying a notice on the monitor of the television is temporarily operated.

결과적으로, 상기 냉매유출알림부(70)가 먼저 작동하며 모니터에 알림문구를 디스플레이 된 상태에서 텔레비전의 메인전원이 오프된다.As a result, the refrigerant discharge notification unit 70 operates first, and the main power source of the television is turned off while the notification message is displayed on the monitor.

그래서, 시청자는 커플러조립체(41)에서 냉매(46)의 유출을 인식하고, 수리업자에게 수리를 요청하게 됨으로써, 장기간의 냉매(46) 유출을 방치하지 않게 되어 텔레비전 내부의 고장을 방지하게 된다.Thus, the viewer recognizes the leakage of the refrigerant 46 from the coupler assembly 41 and requests a repairer for repair, thereby preventing the refrigerant 46 from leaking for a long time, thereby preventing a breakdown in the television.
