Description

필터교환 알림장치 { Alarm system for filter change }Filter change notification device {Alarm system for filter change}

본 발명은 차량 공조 시스템에 사용되는 필터의 교환시기를 자동적으로 알려주는 필터교환 알림장치에 관한 것으로서, 특히 필터의 오염 정도를 감지하여 필터교환 여부를 판단하여 경고함으로써 오염된 필터로 인한 피해를 입지 않도록 하는 필터교환 알림장치에 관한 것이다.The present invention relates to a filter replacement notification device that automatically notifies the replacement time of the filter used in the vehicle air conditioning system, and in particular, by detecting the filter replacement by detecting the degree of contamination of the filter to warn the damage caused by the contaminated filter The present invention relates to a filter change notification device.

일반적으로 차량 공조시스템은 도 1에 도시된 바와 같이 외부 공기를 유입시키는 블로워(11)와, 상기 블로워(11)에 의해 유입된 공기를 냉각시키는 증발기(13)와, 상기 블로워(11)에 의해 유입된 공기의 온도를 상승시키는 히터코어(14)와, 상기 증발기(13)의 후방에 설치되어 유입된 공기속의 먼지를 제거하는 필터(16)와, 상기 블로워(11)의 전방에 설치되어 유입되는 공기량을 조절하는 제1도어(12)와, 상기 히터코어(14)의 측부에 설치되어 유입된 공기를 히터코어 방향으로 안내하는 제2도어(15)로 구성되어 있다.In general, the vehicle air conditioning system includes a blower 11 for introducing external air, an evaporator 13 for cooling the air introduced by the blower 11, and the blower 11, as shown in FIG. Heater core 14 for raising the temperature of the introduced air, a filter 16 installed at the rear of the evaporator 13 to remove dust in the introduced air, and installed in front of the blower 11 to enter The first door 12 to adjust the amount of air to be made, and the second door 15 is installed on the side of the heater core 14 to guide the introduced air in the direction of the heater core.

상기와 같이 구성된 종래의 차량 공조 시스템은 계절에 따라 증발기 또는 히터코어가 작동되어 실내를 냉방 또는 난방하게 된다.In the conventional vehicle air conditioning system configured as described above, the evaporator or the heater core is operated according to the season to cool or heat the room.

블로워(11)가 작동되면 외부 공기가 유입되고, 유입된 공기는 증발기(13)를 거쳐 실내와 연결된 각종 도어를 통해 실내로 유입된다. 이때, 상기 블로워(11)에 의해 유입되는 공기의 양은 블로워(11)의 전방측에 설치된 제1도어(12)의 개도에 따라 달라지게 된다. 차량의 운행 시기가 여름철인 경우에는 증발기(13)가 작동되고 있으므로, 블로워(11)에 의해 유입된 공기는 증발기(13)를 통과하면서 냉각된 후 실내로 유입되어 실내를 냉방하게 된다. 겨울철인 경우에는 증발기(13)는 작동되지 않고 히터코어(14)가 작동되고 있으므로, 제2도어(15)가 히터코어(14) 측의 통로를 개방하여 증발기(13)를 통과한 공기가 히터코어(14)를 거쳐 실내로 유입되도록 함으로써, 실내를 난방하게 되는 것이다.When the blower 11 is operated, outside air is introduced, and the introduced air is introduced into the room through various doors connected to the room via the evaporator 13. At this time, the amount of air introduced by the blower 11 depends on the opening degree of the first door 12 installed at the front side of the blower 11. Since the evaporator 13 is operated when the driving time of the vehicle is summer, the air introduced by the blower 11 is cooled while passing through the evaporator 13 and then flows into the room to cool the room. In winter, since the evaporator 13 is not operated and the heater core 14 is operated, the air passed through the evaporator 13 by opening the passage on the heater core 14 side is heated. By allowing the core 14 to flow into the room, the room is heated.

그런데, 상기 블로워(11)를 통해 유입되는 공기는 전혀 정화되지 않은 공기이므로 오염의 우려가 있다. 따라서, 실내의 쾌적성을 향상시키기 위하여 증발기(13)의 후면에 필터(16)가 설치되며, 증발기(13)를 통과한 외부 공기가 필터(16)를 통과하면서 먼지 등의 이물질이 걸러지게 되므로 실내의 쾌적성이 향상되는 것이다.By the way, the air introduced through the blower 11 is air that is not purified at all, there is a fear of contamination. Therefore, the filter 16 is installed at the rear of the evaporator 13 in order to improve the comfort of the room, and since the foreign air passing through the evaporator 13 passes through the filter 16, foreign substances such as dust are filtered out. The comfort of the room is improved.

그러나, 필터(16)는 공기의 유동과 직접 관련되는 것으로, 필터(16)의 장착에 따라 풍량이 감소되는 현상이 발생된다. 즉, 새로 필터(16)를 장착하더라도 5~10% 정도의 풍량 저하는 감수하여야 하며, 주행이 계속됨에 따라 필터(16)가 오염되므로, 실내로 유입되는 풍량은 점점 줄어들게 된다.However, the filter 16 is directly related to the flow of air, so that the amount of air flow decreases with the mounting of the filter 16. That is, even if the filter 16 is newly installed, the air volume drop of about 5 to 10% is to be taken. As the filter 16 is contaminated as the driving continues, the amount of air flowing into the room is gradually reduced.

이와 같이 필터(16)의 오염으로 풍량이 감소되면 공조성능에도 악영향을 주게 되는데, 대부분의 운전자는 필터(16)의 장착 여부를 모르고 있으며 필터(16)의 교환에 대한 인식도 적은 편이다.As such, when the air volume is reduced due to the contamination of the filter 16, the air conditioning performance is adversely affected. Most drivers do not know whether the filter 16 is mounted, and the recognition of the replacement of the filter 16 is less common.

다시 말해서, 종래의 차량용 공조 시스템에는 필터의 교환 여부를 확인할 수 있는 장치가 없어 오염된 필터로 인하여 공조 성능이 악화되고 오염된 공기가 실내로 유입되어 실내 환경에 심각한 악영향을 주는 문제점이 있는 것이다.In other words, the conventional vehicle air conditioning system does not have a device for checking whether the filter is replaced, there is a problem that the air conditioning performance is deteriorated due to the contaminated filter and the contaminated air is introduced into the room, which seriously affects the indoor environment.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 차량용 공조 시스템에 장착되는 필터의 오염을 감지하여 오염도가 심해질 경우 필터를 교환하라는 메시지를 운전자에게 제공하여 항상 쾌적한 실내 환경이 되도록함과 동시에 공조 성능을 최적화 할 수 있도록 한 필터교환 알림장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems of the prior art, by detecting the contamination of the filter mounted on the vehicle air conditioning system to provide a message to the driver to replace the filter when the pollution degree is severe to always be a comfortable indoor environment At the same time, the purpose of the present invention is to provide a filter change notification device to optimize the air conditioning performance.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

본 발명에 의한 필터교환 알림장치는 도 2에 도시된 바와 같이 공조 시스템의 필터(66) 오염을 감지하는 먼지 감지센서(51)와, 상기 필터(66)의 오염이 심할 경우 운전자에게 이를 알려주는 경보수단(53)과, 상기 먼지 감지센서(51)의 신호에 따라 상기 경보수단(53)을 작동시키는 제어부(52)로 구성된다.The filter change notification device according to the present invention, as shown in FIG. 2, detects contamination of the filter 66 of the air conditioning system 51, and notifies the driver when the contamination of the filter 66 is severe. Alarm means 53 and the control unit 52 for operating the alarm means 53 in accordance with the signal of the dust sensor 51.

상기 먼지 감지센서(51)는 상기 필터(66)의 측부에 설치된 발광부(51a)와, 상기 필터(66)를 개재하여 상기 발광부(51a)와 대향되게 설치되고 상기 발광부(51a)의 빛을 감지하여 상기 제어부(52)로 전송하는 수광부(51b)로 구성된다. 또, 상기 경보수단(53)은 운적석 앞쪽의 대시보드에 설치된 경고등(53a)이거나 경고음을 발생하는 벨(53b) 또는 특정 소음을 발생하는 알람장치(53c)이며, 이들이 단독으로 사용되거나 복합적으로 사용될 수 있다.The dust detecting sensor 51 is disposed to face the light emitting unit 51a via the light emitting unit 51a provided on the side of the filter 66 and the filter 66, and the light emitting unit 51a The light receiver 51b detects light and transmits the light to the controller 52. In addition, the alarm means 53 is a warning light (53a) installed in the dashboard of the front of the meteorite seat or a bell 53b for generating a warning sound or an alarm device (53c) for generating a specific noise, these are used alone or in combination Can be used.

상기와 같이 구성된 본 발명의 필터교환 알림장치는 도 6에 도시된 바와 같이 기존의 차량 공조 시스템에 적용되어 사용된다.The filter replacement notification device of the present invention configured as described above is applied to and used in an existing vehicle air conditioning system as shown in FIG. 6.

블로워(61)가 작동되면 외부 공기가 유입되고, 유입된 공기는 증발기(63)를 거친 후 필터(66)를 통과하면서 오염물질이 걸러진 후, 실내와 연결된 각종 도어를 통해 실내로 유입된다. 이때, 상기 블로워(61)에 의해 유입되는 공기의 양은 블로워(61)의 전방측에 설치된 제1도어(62)의 개도에 따라 달라지게 된다.When the blower 61 is operated, external air flows in, and the introduced air passes through the evaporator 63 and filters the contaminants while passing through the filter 66, and then flows into the room through various doors connected to the room. At this time, the amount of air introduced by the blower 61 varies depending on the opening degree of the first door 62 installed at the front side of the blower 61.

그런데, 상기 필터(66)가 오염될 경우 상기 필터(66)의 측부에 설치된 먼지 감지센서(51)가 이를 감지하여 제어부(52)로 신호를 보내게 된다. 즉, 필터(66)에 많은 먼지가 끼어 필터(66)의 오염 상태가 심해질 경우 수광부(51b)는 발광부(51a)의 불빛 신호를 전혀 받지 못하게 되므로, 제어부(52)는 필터(66)가 오염된 것을 알 수 있게 된다. 따라서, 제어부(52)는 경고등(53a)이나 벨(53b) 또는 알람장치(53c)을 통하여 이를 운전자에게 알리게 되고, 운전자는 필터(66)를 조기에 교환할 수 있게 된다.However, when the filter 66 is contaminated, the dust sensor 51 installed on the side of the filter 66 detects this and sends a signal to the controller 52. That is, when a lot of dust is caught in the filter 66 and the contamination of the filter 66 becomes severe, the light receiving unit 51b does not receive the light signal of the light emitting unit 51a at all. You will notice that it is contaminated. Accordingly, the controller 52 notifies the driver of the alarm via the warning light 53a, the bell 53b, or the alarm device 53c, and the driver can replace the filter 66 at an early stage.

물론, 차량 공조 시스템은 상기 필터(66)의 오염과 무관하게 작동된다. 즉, 여름철에는 증발기(63)가 작동되어 실내를 냉방하고, 겨울철에는 히터코어(64)가 작동됨과 동시에 제2도어(65)가 히터코어(64) 측의 통로를 개방하여 증발기(63)를 통과한 공기가 히터코어(64)를 거쳐 실내로 유입되도록 함으로써, 실내를 난방하게 되는 것이다.Of course, the vehicle air conditioning system is operated irrespective of the contamination of the filter 66. That is, in the summer, the evaporator 63 is operated to cool the room, and in the winter, the heater core 64 is operated and the second door 65 opens the passage on the heater core 64 side to open the evaporator 63. By passing the air passed through the heater core 64 into the room, it is to heat the room.

이와 같이, 본 발명의 필터교환 알림장치는 차량 공조 시스템에서 사용되는필터의 오염을 감지하여 조기에 교환할 수 있게 하므로 쾌적한 실내 환경을 유지할 수 있고 공조 성능을 최적화 할 수 있는 이점이 있다.As described above, the filter change notification device of the present invention detects the contamination of the filter used in the vehicle air conditioning system and replaces the filter early, thereby maintaining a comfortable indoor environment and optimizing the air conditioning performance.
