Description

차량 에어컨용 필터 교환주기 경보장치{ALARM SYSTEM FOR AIR FILTER SWAPPING TIME OF AIRCONDITION}ALARM SYSTEM FOR AIR FILTER SWAPPING TIME OF AIRCONDITION}

본 발명은 차량 에어컨용 필터 교환주기 경보장치에 대한 것으로, 필터의 전체 면적을 수개의 단위 면적으로 나누고 그 각각의 단위면적에 개별적인 압력센서를 구비하여 이들 압력센서에서 감지되는 전체적인 압력차에 의해 경보가 제공되도록 하는데 특징이 있는 것이다.The present invention relates to a filter replacement cycle alarm device for a vehicle air conditioner, and divides the entire area of the filter into several unit areas and includes an individual pressure sensor in each unit area to be alerted by the overall pressure difference detected by these pressure sensors. Is to be provided.

일반적으로 차량용 에어컨은 도 1에서 보는 바와 같이 덕트(1)를 구비하고, 그 내부에 필터(4)와, 증발기 코일(2a)과, 히터 코일(2b)과, 그 안쪽에서 외부의 공기를 강제 흡입하기 위한 송풍기(3)를 구비한다.In general, an air conditioner for a vehicle has a duct 1 as shown in FIG. 1, forcing a filter 4, an evaporator coil 2a, a heater coil 2b, and external air from the inside thereof. A blower 3 for suctioning is provided.

그리고 이와 같은 공조장치에서 사용하고 있는 필터(4)는 장시간 사용할 경우 필터링 효과가 떨어지기 때문에 주기적으로 교체하여야 하는데, 그 교체주기는 운행환경과, 운행거리와, 운행시간 등을 총체적으로 감안하여 파악한다.And the filter (4) used in such an air conditioning device should be replaced periodically because the filtering effect is inferior when used for a long time, the replacement cycle is determined in consideration of the operating environment, the driving distance, and the operating time as a whole do.

그러나 종래의 공조장치에 있어서는 상기와 같은 여건 및 사항들을 감안하되 단순히 운전자의 경험에 의해 판단하기 때문에 때로는 너무 늦게 교체하여 차량 실내의 공기가 나빠지기도 하고, 때로는 너무 자주 교환하여 필터 비용이 가중되기도 한다.However, in the conventional air conditioner, the above conditions and matters are taken into consideration, but simply determined by the driver's experience, so that the air in the vehicle is badly replaced because it is replaced too late, and sometimes the filter cost is increased by replacing it too often. .

따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출한 것으로, 발명의 주된 목적은 필터의 안쪽에 압력감지센서를 부착하므로써 그 필터의 표면에 이물질이 누적되어 공기 통과 압력이 떨어지는 것을 감지할 수 있도록 하는데 있으며, 더 나가서 압력센서에 의한 필터교체시기를 정확히 경보하므로써 차량실내의 공기가 항상 쾌적한 상태를 유지하면서 필터의 남용이 없도록 하는데 있다.Therefore, the present invention has been made to solve the above-mentioned conventional problems, the main object of the invention is to attach a pressure sensor to the inside of the filter to detect that the foreign matter accumulates on the surface of the filter to detect the drop in air passage pressure In addition, it is possible to go out further and accurately alarm the timing of filter replacement by the pressure sensor so that the air in the vehicle cabin is always kept comfortable and there is no abuse of the filter.

상기 목적을 달성하기 위한 본 발명의 특징적인 구성 수단은 차량의 실내로 연결된 덕트와, 상기 덕트의 내부에 증발기 코일과, 히터 코일과, 그 안쪽에서 외부의 공기를 강제 흡입하기 위한 송풍기를 차례로 구성하고, 상기한 증발기 코일의 앞에 에어 필터를 구비한 차량용 에어컨 장치에 있어서, 상기한 필터의 안쪽에 압력센서를 구비하되, 상기 필터의 넓이를 다수로 구획한 후, 그 구획된 각각의 위치 마다 하나씩의 압력센서들을 설치하여, 그 압력센서들의 측정값이 미리 설정된 설정값 이하로 떨어질 때, 차량 실내의 경보수단에 전달되도록 하는 것이다.Characteristic constituent means of the present invention for achieving the above object comprises a duct connected to the interior of the vehicle, an evaporator coil in the interior of the duct, a heater coil, and a blower for forcibly sucking outside air from the inside thereof In the vehicle air conditioner having an air filter in front of the evaporator coil, a pressure sensor is provided inside the filter, and the width of the filter is divided into a plurality of sections, one for each of the divided positions. By installing the pressure sensors of the, so that when the measured value of the pressure sensors falls below a predetermined set value is to be transmitted to the alarm means in the vehicle interior.

이하 본 발명의 구성 및 작동을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

에어컨 장치는 차량의 실내로 연결된 덕트(1)와, 상기 덕트의 내부에 증발기 코일(2a)과, 히터 코일(2b)과, 그 안쪽에서 외부의 공기를 강제 흡입하기 위한 송풍기(3)를 차례로 구성하고, 상기한 증발기 코일(2a)의 앞에 에어 필터(4)를 구비한다.The air conditioner includes a duct 1 connected to a vehicle interior, an evaporator coil 2a, a heater coil 2b, and a blower 3 for forcibly drawing outside air from the inside of the duct. It comprises and the air filter 4 is provided in front of the above-mentioned evaporator coil 2a.

이때, 본 발명에서는 상기한 필터(4)의 안쪽에 압력센서를 구비하되, 상기 필터(4)의 넓이를 다수로 구획한 후, 그 구획된 각각의 위치 마다 하나씩의 압력센서(5)들을 설치하여, 그 압력센서(5)들의 측정값이 미리 설정된 설정값 이하로 떨어질 때, 차량 실내의 경보수단(6)에 전달되도록 하는 것이다.At this time, the present invention is provided with a pressure sensor on the inside of the filter (4), after partitioning the width of the filter (4) a large number, one pressure sensor (5) is installed for each position of the partition Thus, when the measured values of the pressure sensors 5 fall below a preset set value, the pressure sensor 5 is transmitted to the alarm means 6 in the vehicle interior.

여기서 경보수단(6)은 통상적으로 널리 사용되는 경보음 발생수단이나 점등 램프로 하고, 이는 상기한 여러개의 압력센서(5)들 중에서 과반수 이상이 미리 설정된 설정값 이하의 측정값이 나타날 때 경보를 전달하도록 한다.In this case, the alarm means 6 is an alarm sound generating means or a lighting lamp which are generally used. The alarm means 6 generates an alarm when a measured value of more than half of the pressure sensors 5 described above is less than or equal to a preset value. To be delivered.

상기와 같이 구성된 본 발명은 차량의 에어컨을 사용함에 있어서 여과 능력이 떨어지면 경보가 전달된다.According to the present invention configured as described above, the alarm is transmitted when the filtration capacity is reduced in using the air conditioner of the vehicle.

즉, 덕트(1)로 유입되는 공기를 필터(4)가 여과할 때, 필터에 이물질이 계속해서 누적되면 압력이 떨어진다.That is, when the filter 4 filters the air which flows into the duct 1, if a foreign material continues to accumulate in a filter, a pressure will fall.

압력이 떨어지면 그 떨어지는 압력값을 일정 거리를 가지고 배치된 각 구획 부분의 압력센서가 감지하게 되는데, 이물질은 전체 면적에 고르게 쌓인다고 인정할 수 없으므로 어느 한 곳의 압력센서 측정값으로 경보음을 울리는 것이 아니라 적어도 2개 이상 또는 과반수 이상의 압력센서 측정값에 의해 경보가 제공된다.When the pressure drops, the pressure sensor of each compartment placed at a certain distance is detected by the pressure drop. Since foreign substances cannot be recognized as being evenly accumulated in the entire area, it is necessary to sound an alarm sound by the pressure sensor measurement at any one place. In addition, an alarm is provided by at least two or more than half of the pressure sensor readings.

따라서 사용자는 경보가 제공될 때 필터를 갈아주면 된다.Therefore, the user can change the filter when an alarm is provided.

위에서 상세히 설명한 바와 같은 본 발명은 필터의 안쪽에 압력감지센서를 부착하여 필터의 표면에 이물질이 누적되었을 때 공기 통과 압력이 떨어지는 것을 감지할 수 있도록 하되, 필터의 면적을 다수로 구획하고 그 구획된 면적에 하나씩의 압력센서를 부착하였기 때문에 일 부분에 이물질이 집중적으로 몰려 그 부분의압력이 떨어지더라도 나머지 부분에서 충분히 여과가 될 경우 경보가 제공되지 않으며, 더 나가서 과반수 이상의 압력센서들이 모두 떨어진 압력을 감지 할 때 교체 경보가 제공되기 때문에 필터의 교체시기를 가장 적절하게 할 수 있는 장점이 있다.As described in detail above, the present invention attaches a pressure sensor to the inside of the filter to detect an air pressure drop when foreign matter accumulates on the surface of the filter, but divides the area of the filter into a plurality of partitions. Since one pressure sensor is attached to the area, if there is a concentration of foreign substances in one part and the pressure in that part drops, the alarm is not provided if the filter is sufficiently filtered in the remaining part. The replacement alarm is provided when it detects, which has the advantage that the filter replacement time is most appropriate.

따라서 사용자는 필터의 교체를 남발하지 않으면서도 실내 공기가 항상 쾌적한 상태를 유지할 수 있게 되는 것이다.Therefore, the user can always keep the indoor air comfortable without overusing the replacement of the filter.
