자동차용 공기조화기의 필터 교환 경고장치{Warning device for exchanging filter of airconditioner for automobile}Warning device for exchanging filter of air conditioner for automobiles {Warning device for exchanging filter of airconditioner for automobile}

본 발명은 자동차용 공기조화기의 필터 교환 경고장치에 관한 것으로서, 더욱 상세하게는 필터에 흡입되는 공기의 압력을 이용하여 압력 차이가 설정값 이상 발생하면 회동구조로 형성된 필터의 회전 작동으로 공기가 필터를 거치지 않고 자동차 실내로 유입되도록 하여 에어컨 및 히터의 성능을 향상시키고 또한, 갭(gap)센서가 작동되도록 하여 운전자에게 경고등의 점등을 인지시킴으로써, 필터의 교환을 알릴 수 있도록 하는 자동차용 공기조화기의 필터 교환 경고장치에 관한 것이다.The present invention relates to a filter replacement warning device for an air conditioner for a vehicle, and more particularly, when a pressure difference occurs by using a pressure of the air sucked into the filter more than a set value, the air is rotated by the rotational operation of the filter formed in the rotating structure. Car air conditioning that notifies the replacement of the filter by improving the performance of air conditioners and heaters by passing them into the car interior without going through the filter, and by enabling the gap sensor to be activated to recognize the warning light of the driver. The present invention relates to a filter change warning device for a machine.

일반적으로, 자동차의 공기조화기에서 자동차의 실내에 공기를 순환시키는 공기순환유니트에는 공기가 흡입되어 그 유동력이 증가되도록 블로워 장치가 설치되어 있으며, 상기 블로워 장치의 일측에는 상기 블로워 장치에 의해 유동력이 증가된 공기를 냉기로 변화시키도록 그 내부에 냉매가 흐르는 증발기가 설치되어 있고, 상기 증발기의 일측에는 상기 블로워 장치에 의해 유동력이 증가된 공기를 온기로 변화시키도록 히터가 설치되어 있으며, 상기 히터의 일측에는 자동차 실내로 공기가 유출하도록 형성되어 있다.In general, a blower device is installed in an air circulation unit for circulating air in a car interior of an automobile air conditioner so that air is sucked and the flow force thereof is increased, and one side of the blower device is provided by the blower device. An evaporator in which a refrigerant flows is installed inside the evaporator so as to change the power of the air increased to cold, and a heater is installed at one side of the evaporator to change the air having increased flow force to the warmth by the blower device. One side of the heater is formed so that air flows into the vehicle interior.

상기 블로워 장치는 임펠러와, 축부재를 매개물로 하여 상기 임펠러를 회전시키는 모터로 이루어져 있다.The blower device is composed of an impeller and a motor for rotating the impeller via the shaft member.

이때, 상기 블로워 장치, 증발기 및 히터는 각각의 케이스에 의해 유니트화되어 유니트로서 서로 분리가능케 조립되어 있다.At this time, the blower apparatus, the evaporator and the heater are unitized by respective cases, and are assembled to be separated from each other as a unit.

상기 증발기가 위치하는 유니트, 즉 냉각유니트의 케이스의 내부에는 상기증발기를 통과하는 공기를 필터링하도록 필터가 상기 증발기의 평면과 평행으로 설치되어 있다.A filter is installed in parallel with the plane of the evaporator so as to filter the air passing through the evaporator in the unit in which the evaporator is located, that is, the case of the cooling unit.

이와 같이 구성된 종래의 자동차 공기조화기의 공기순환유니트에서 차량내부를 냉방하도록 도시하지 않은 조작수단을 조작하면, 블로워 장치의 모터가 동작하여 임펠러가 회전하고, 냉매사이클이 형성되어 증발기 내에 냉매가 흐르게 되는 동시에 상기 증발기를 지나는 공기는 상기 증발기 내에 흐르는 냉매와 열교환되어 냉기로 바뀌며, 상기 냉기는 차량내부에 토출된다.In the air circulation unit of the conventional automobile air conditioner configured as described above, when the operation means (not shown) is cooled to cool the inside of the vehicle, the motor of the blower device is operated so that the impeller rotates, a refrigerant cycle is formed, and the refrigerant flows in the evaporator. At the same time, the air passing through the evaporator is exchanged with the refrigerant flowing in the evaporator to be changed to cold, and the cold air is discharged in the vehicle.

한편, 상기 증발기를 통과하는 공기는 필터에 의해 필터링되어 실내에는 깨끗한 공기가 공급된다.On the other hand, the air passing through the evaporator is filtered by a filter is supplied clean air to the room.

그리고, 자동차 공기조화기를 장시간 가동하면, 상기 필터에 이물질이 끼게 되어 상기 필터는 제기능를 발휘하지 못하므로, 필터를 일정한 주기마다 교환하게 된다.When the automobile air conditioner is operated for a long time, foreign matter is caught in the filter, and the filter does not function properly. Therefore, the filter is replaced at regular intervals.

그런데, 종래의 공기조화기의 필터를 교환하지 않을 경우, 필터의 입구에 이물질이 쌓임으로 인해 풍속 및 풍량 저하가 생기게 되고, 그 결과 에어컨 및 히터 성능을 저하시키며, 차량 실내로 이물질이 유입되어 악취가 발생하는 결과를 낳는다.However, when the filter of the conventional air conditioner is not replaced, debris accumulates at the inlet of the filter, resulting in a decrease in wind speed and air volume, resulting in deterioration of air conditioner and heater performance, and inflow of debris into the vehicle interior. Yields results that occur.

특히, 에어컨 시스템의 풍량 감소로 인한 열교환 성능 저하로 냉방 성능이 불량하며, 상기 에어컨 시스템 내의 고압 발생 및 고장 발생의 원인이 된다.In particular, the cooling performance is poor due to a decrease in heat exchange performance due to a decrease in the air volume of the air conditioning system, causing high pressure and failure in the air conditioning system.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, ECU가 필터를 통과하는 공기의 풍속압이 설정값 이상이면 풍속압 센서가 이를 감지하여 ECU에 전달하고, 상기 ECU에 의한 필터의 회전 작동으로 공기가 필터를 거치지 않고 자동차 실내로 유입되도록 하여 에어컨 및 히터의 성능을 향상시키고 또한, 그로인해 갭(gap)센서가 작동되도록 하여 운전자에게 경고등의 점등을 인지시킴으로써, 필터의 교환을 알릴 수 있도록 하는 자동차용 공기조화기의 필터 교환 경고장치를 제공하는데 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, if the wind pressure of the air passing through the filter ECU is a wind speed pressure sensor detects it and delivers it to the ECU, and the filter of the filter by the ECU The rotational operation allows air to flow into the car interior without passing through the filter, improving the performance of the air conditioner and heater, and thereby allowing the gap sensor to be activated to notify the driver of the lighting of the warning lamp, thereby informing the replacement of the filter. It is an object of the present invention to provide a filter change warning device for an automobile air conditioner.
