본 고안은 차량용 에어콘의 냉매용량 표시장치에 관한 것으로, 특히 에어콘의 부족상태를 다단계로 식별가느케 하여 에어콘의 정상가동을 위한 준비에 만전을 기함과 정비시점을 알 수 있게 한 냉매용량 표시장치에 관한 것이다.The present invention relates to a refrigerant capacity display device for an air conditioner for a vehicle. In particular, the refrigerant capacity display device for identifying the air condition shortage status in multiple stages to fully prepare for normal operation of the air conditioner and to know the maintenance time point. It is about.

현재, 운행되는 각종의 차량은 차량고급화 추세에 따라 대부분 차체내에 에어콘을 포함하고 있으며.. 통상 라디에이터(radiator)와 연결될 수 있게 설치되는데. 크로스블로워가 내장된 하우징과 냉매순환용 튜브를 거친 공기가 차량의 실내로 연결된 벤틸레이션관으로 유입되어 분출될 수 있게 컴프레셔 및 구동모우터등의 각각 내설되는 것이다.At present, various kinds of vehicles operating include air conditioners in most of the vehicle bodies in accordance with the trend of vehicle enhancement. Usually, they are installed to be connected to a radiator. The air passing through the housing with the built-in cross blower and the tube for refrigerant circulation flows into the ventilation tube connected to the interior of the vehicle and is blown out by the compressor and the driving motor.

상기한 에어콘은 에어콘의 고유기능인 찬공기의 분사를 위행서 냉매의 주입이 필요하다. 냉매는 열교환기에서 열을 빼내기 위한 전달매체로 통한 프레온가스(Fr2)The air conditioner is required to inject the refrigerant for the injection of cold air which is a unique function of the air conditioner. Refrigerant is a freon gas (Fr2) through the transfer medium to extract heat from the heat exchanger

및 이의 대체물질로 CHCIF2 가 통용되고 있다.CHCIF2 is commonly used as a substitute.

에어콘의 냉매 교환주기는 자주 발생되지 않으나 혹서기에 과다한 사용이나 혹은 장기간의 비상용시에는 증밝이 되어 교환주기가 매우 단축된다. 에어콘은 간헐적으로 작동시켜 주어야 되며, 이는 냉매의 순환으로 인한 운동성부여부와 외부 증발을 막기 위함이다.Refrigerant replacement cycles of air conditioners are not frequent, but they become brighter in case of excessive use in the summer or long-term emergency use, and the replacement cycle is very short. The air conditioner should be operated intermittently, to prevent motility and external evaporation due to circulation of the refrigerant.

에어콘의 냉매주입은 최초 설치될 당시에 주입이 되고, 이후는 운전자 자신이 냉매 교환시기를 연차분으로 적당히 체크하여 추입하였다.Refrigerant injection of air conditioner was injected when it was first installed, and after that, the driver himself checked the refrigerant replacement time appropriately for each year.

따라서, 주행중에 냉매가 떨어져 에어콘의 기능이 상실될 우려가 높았고, 특히 장시간의 비사용후 처음 사용시에는 증발이 다 되어버린 경우가 발생될 수 있는 것이다.Therefore, there is a high possibility that the air conditioner may be lost due to the refrigerant falling off while driving, and in particular, when the first use after a long period of non-use occurs, evaporation may occur.

상기한 운전자의 체크는 내우 불환전한 것으로, 실제적으로 냉매의 부족여부등을 직접 육안으로 상켜보기는 매우 어려워 언제 냉매가 부족할지 가늠키 어렵고, 따라서 냉매가 떨어진 후에야 경정비센타를 찾아 수리여부와 냉매를 주입하는 등 시간적, 경제적으로 많은 불편함이 있었던 것이다.The driver's check is internally unchanged, and it is very difficult to visually check whether there is a shortage of refrigerant, so it is difficult to determine when the refrigerant is insufficient. There was a lot of discomfort, such as injecting time and economics.

본원은 상기의 제반결점을 감안하여 안출된 것으로 냉매가스의 부족여부를 다단계로 감지하여 별도의 발광다이오드에 열결되에 하여 부족시에 즉각 주입되도록 함으로 에어콘의 수명증대와 혹서기에 쾌적한 운전이 가능한 것이며, 아울러 교한시기 또는 체크될 수 있는 목적을 갖는 것이다.The present application was devised in consideration of the above-mentioned shortcomings, and it detects the shortage of refrigerant gas in multiple stages and connects it to a separate light emitting diode so that it can be injected immediately when there is a shortage. In addition, it has a purpose that can be checked or checked.

본 고안은 상기 목적의 달성을 위해 가스압력 측정용 센서를 마련하고 가스 압력차에 따라 최초 측정된 압력과 그 다음 압력과의 차를 비교하는 비교부, 그리고 비교치를 수신하여 해당 표시부를 전달하는 수신부와 표시부로 구성된다.The present invention provides a sensor for measuring the gas pressure to achieve the above object, a comparison unit for comparing the difference between the first measured pressure and the next pressure according to the gas pressure difference, and a receiver for receiving the comparison value and transmitting the display unit And a display unit.

이하 첨부도면에 의거한 보다 상세한 설명은 다음과 같다.A more detailed description based on the accompanying drawings is as follows.

도면, 제1도는 본 고안의 구성상태를 도시한 블럭도로써, 차량내부에 설치된 에어콘의 냉매가스 공급통(10)이 있어서, 상기 냉매가스 공급통(10)의 주입구에 가스압력 측정용 센서(11)를 고정함고, 상기 가스압력 측정용 센서(11)로 부터 전달된 내용을 처음 설정된 압력차와 상호 비교하는 비교부(12)와, 상기 비교부(12)로 부터 비교되어 선별된 내용을 수신하는 수신부(13)와 상기 부신부(13)에서 각 당계별로 부내주는 신호를 순차적으로 한 표시부(14)가 차량이 인스트루먼트 패널(15) 일측에 설치되게 한 것이다.Figure 1 is a block diagram showing the configuration of the present invention, there is a refrigerant gas supply cylinder 10 of the air conditioner installed in the vehicle, the gas pressure measuring sensor (in the inlet of the refrigerant gas supply cylinder 10 ( 11) is fixed, the comparison unit 12 for comparing the contents transmitted from the gas pressure measuring sensor 11 with the first set pressure difference, and the contents selected and compared from the comparison unit 12 The receiving unit 13 and the display unit 14 sequentially receiving signals from the adrenal unit 13 for each sugar party are installed on one side of the instrument panel 15.

상기한 본 고안은 도면 제2도에 작동관계에 대한 흐름도가 도시되어 있는바, 표시부(14)느 다단계 발광소자(LED)를 채택하여 식별가능케 할 수 있다.The present invention described above is shown in the flow chart of the operation relationship in Figure 2, the display unit 14 can be identified by adopting a multi-level light emitting device (LED).

최초 냉매가스 공급통(10)의 만입된 냉매는 가스압력 측정용 센서(11)로 압력에 따른 용량치가 산출되어 설정되어 설정되며, 이후 계속된 냉매의 사용과 대기증발에 따라 줄어드는 압력치를 초기 설정된 압력치와 비교부(12)에서 검토한 후 만야 나중에 축정된 압력이 초기 설정된 압력이 1/5 상태이면 이를 수신부(13)가 받아 1차 노란색이 발광소자를 점등하여 인스트루먼트 패널(15)상의 표시부(14)에 나타낸다.The refrigerant charged in the initial refrigerant gas supply cylinder 10 is set by setting the capacity value according to the pressure by the gas pressure measuring sensor 11, and then setting the pressure value which decreases according to the continuous use of the refrigerant and atmospheric evaporation. After reviewing the pressure value and the comparison unit 12, the pressure that is later established is received by the receiver 13 when the initial set pressure is 1/5. The primary yellow light turns on the light emitting element to display the display unit on the instrument panel 15. It shows in (14).

만약 최소 비교치인 1/5 에 미치지 못하면 다시 측정준비단계로 돌아가 대기하며 1차 비교후 계속된 용량의 감소로 설정치의 1/7상태에 이르면 동일과정으로 수신부(13)에의해 2차 주홍색 경고등의 표시부(14)에 점등되는 것이다.If the minimum comparison value of 1/5 is not reached, the process returns to the measurement preparation stage and waits again. After the first comparison, the capacity decreases and the 1/7 state of the set value is reached. The display unit 14 lights up.

역시 ,1/7 이하 상태이면 다시 1차 비교후 상태로 대기하며 최종적으로 가스의 압력치가 초기 설정 당시의 1/10 이하로 내려가면 3차 붉은색 경고등의 표시부 (14)에 나타낼수 있도록 한 것이며, 1/10이하가 아닐시에 는 전술한 관정과 동일하게 대기한다.Also, if it is less than 1/7, it will stand by after the first comparison, and finally, if the gas pressure is lowered to 1/10 or less at the time of initial setting, it can be displayed on the display unit 14 of the 3rd red warning light. If it is not less than 1/10, it waits in the same manner as the above-mentioned well.

이후 , 냉매가스이 충입이 이루어져 초기의 설정치 압력과 같아실 때 이를 측정하여 yes 면 최초의 측정대기상태로 되돌아가고 초기설정치와 비교하여 부족하면 에러의 발생으로 표시부(14)를 통한 3차 경고등의 점등도게 한 것이다.After that, when the refrigerant gas is charged and is equal to the initial set pressure, it is measured, and if yes, it returns to the initial measurement standby state and if it is insufficient compared with the initial set value, the third warning light is turned on through the display unit 14 due to an error. It is helped.

따라서, 본 고안은 차량 관리자가 인스트루먼트 패널(15)상의 표시부(14)를 통해 적절한 냉매가스이 주입시기를 알 수 있어 주행중 발생될 수 있는 냉매의 부족에 따른 에어콘 기능상실을 방지할 수 있으며, 정비시점이 산출시기를 체크할 수 있어 쾌적하고 원할한 차량의 운행에 일조할 수 있는 제반특징을 갖는다.Therefore, according to the present invention, the vehicle manager can know the appropriate injection time of the refrigerant gas through the display unit 14 on the instrument panel 15, thereby preventing the air conditioner malfunction due to the lack of the refrigerant that can be generated during driving, and at the time of maintenance It is possible to check the timing of the calculation, and it has all the features that can contribute to a comfortable and smooth operation of the vehicle.
