버스용 환풍기의 자동닫힘장치{Auto closed system of ventilation fan for bus}Auto closed system of ventilation fan for buses {Auto closed system of ventilation fan for bus}

본 발명은 버스용 환풍기의 자동닫힘장치에 관한 것으로서, 더욱 상세하게는 차량 운행 후 환풍 스위치를 "OFF" 하지 않고 그대로 방치한 경우, 상시 배터리 전원과 릴레이를 이용하여 환풍기 도어를 자동으로 닫을 수 있도록 함으로써, 환풍기 도어를 통한 빗물이나 먼지 등의 유입을 차단할 수 있도록 한 버스용 환풍기의 자동닫힘장치에 관한 것이다.The present invention relates to an automatic closing device for a bus ventilator, and more particularly, when the ventilator switch is left as it is without turning off the vehicle after driving the vehicle, the ventilator door can be automatically closed using the battery power and the relay at all times. By doing so, the present invention relates to an automatic closing device for a bus fan for blocking rain or dust from entering through the fan door.

일반적으로 버스용 환풍기는 운전자의 "ON/OFF" 스위치 조작에 의해 작동되는 단순한 시스템으로 되어 있으며, 차실내외의 공기를 환풍, 순환, 배기, 흡입시킬 수 있는 4가지 모드를 선택하여 사용할 수 있다.In general, the bus ventilator is a simple system operated by the driver's “ON / OFF” switch operation. There are four modes for ventilating, circulating, exhausting, and inhaling air in and out of the vehicle.

도 1a에 도시한 바와 같이, 운전자가 순환 스위치(10)를 "ON" 조작하여 순환모드를 선택하면, 배터리 전원이 순환 접점(11)을 통해 모터(12)로 공급되어 환풍기 도어(미도시)가 닫혀지게 되고, 모터(12)의 1/2 회전 후, 접점이 바뀌면서 모터(12)의 정지와 함께 순환 접점(11)은 끊어지고 이것과 연동관계에 있는 환풍 접점(13)이 자동으로 연결된다.As shown in FIG. 1A, when the driver selects the circulation mode by operating the circulation switch 10, the battery power is supplied to the motor 12 through the circulation contact 11 to supply a fan door (not shown). Is closed, and after 1/2 rotation of the motor 12, the contact is changed and the circulation contact 11 is disconnected with the stop of the motor 12, and the ventilation contact 13 in linkage with this is automatically connected. do.

여기서, 미설명 부호 14는 퓨즈, 15는 콘덴서를 각각 나타낸다.Here, reference numeral 14 denotes a fuse, and 15 denotes a capacitor.

도 1b에 도시한 바와 같이, 운전자가 환풍 스위치(16)를 "ON" 조작하여 환풍모드를 선택하면, 배터리 전원이 환풍 접점(13)을 통해 모터(12)로 공급되어 환풍기 도어가 열려지게 되고, 모터(12)의 1/2 회전 후, 접점이 바뀌면서 모터(12)의 정지와 함께 환풍 접점(13)은 끊어지고 순환 접점(11)이 자동으로 연결된다.As shown in FIG. 1B, when the driver operates the ventilation switch 16 to "ON" to select the ventilation mode, the battery power is supplied to the motor 12 through the ventilation contact 13 to open the fan door. After 1/2 rotation of the motor 12, the contact is changed and the ventilation contact 13 is disconnected with the stop of the motor 12, and the circulation contact 11 is automatically connected.

이때의 환풍기 도어는 열려진 상태이고, 로터리 방식의 스위치 구조에 따라 순환 스위치(10)는 상대적으로 "OFF" 상태이다.At this time, the fan door is open, and the circulation switch 10 is relatively "OFF" according to the rotary switch structure.

그러나, 차량 운행 후 정차시 운전자가 부주의 등으로 환풍 모드시 환풍 스위치를 "OFF" 하지 않고 그대로 방치하는 경우, 즉 환풍모드를 다른 모드로 바꾸지않고 그대로 놓아두는 경우, 열려져 있는 환풍기 도어를 통해 빗물이나 먼지 등이 유입되어 차량이 지저분해지거나, 손상 또는 고장의 우려가 높은 문제가 있었다.However, when the driver stops the vehicle after driving without leaving the ventilation switch "OFF" in the ventilation mode due to carelessness, that is, leaving the ventilation mode unchanged without changing to another mode, rain or There was a problem that the vehicle is dirty due to the inflow of dust and the like, and there is a high risk of damage or failure.

따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 차량 운행 후 배터리 전원 차단시 상시 배터리 전원과 릴레이를 이용하여 환풍기 도어가 자동으로 닫혀질 수 있도록 함으로써, 운전자의 부주의 등으로 환풍 스위치를 "OFF" 하지 않고 그대로 방치한 경우에도 환풍기 도어를 통한 빗물이나 먼지 등의 유입을 차단할 수 있으며, 이에 따라 차량의 청결상태를 유지할 수 있고 운전자 편의성을 향상시킬 수 있도록 한 버스용 환풍기의 자동닫힘장치를 제공하는데 그 목적이 있는 것이다.Accordingly, the present invention has been made in view of the above, and when the battery power is cut off after the vehicle is driven, the ventilator door may be automatically closed by using the battery power and the relay at all times, so that the ventilation switch is inadvertently changed by the driver. Even if it is left as it is, it is possible to block the inflow of rainwater or dust through the fan door. Therefore, the automatic closing device of the bus ventilator for keeping the vehicle clean and improving the driver's convenience can be prevented. The purpose is to provide.

이하, 첨부한 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 순환 스위치(10) 및 환풍 스위치(16)의 "ON/OFF" 조작을 통해 모터(12)를 작동시키는 방법으로 환풍기 도어를 개폐할 수 있는 버스용 환풍기에 있어서, 상기 순환 스위치(10)와 모터(12) 사이의 회로상에 릴레이(17)를 설치하여 정상시 릴레이(17)의 "OFF" 상태에서 스위치 조작에 따른 모터(12)의 작동을 가능하게 하고, 보조 퓨즈(18)와 상시 배터리 전원을 포함하는 별도의 회로를 릴레이(17)측 스위치 접점과 연결하여 배터리 전원 차단시 릴레이(17)의 "ON" 상태에서 상시 배터리 전원으로 모터(12)를 작동시킬 수 있도록 한 것을 특징으로 한다.The present invention relates to a bus fan for opening and closing a fan door by operating the motor 12 through the " ON / OFF " operation of the circulation switch 10 and the ventilation switch 16, wherein the circulation switch 10 ), The relay 17 is installed on the circuit between the motor 12 and the motor 12 to enable the operation of the motor 12 according to the switch operation in the "OFF" state of the relay 17 in the normal state, and the auxiliary fuse 18 And a separate circuit including the battery power is connected to the switch contact on the relay 17 side so that the motor 12 can be operated with the battery power in the "ON" state of the relay 17 when the battery power is cut off. It features.

또한, 상기 순환 스위치(10)의 전원 인가측에는 콘덴서(15)의 역전압 발생으로 인한 채터링(Chatterring) 현상을 막기 위한 다이오드(19)를 설치한 것을 특징으로 한다.In addition, the power supply side of the circulation switch 10 is characterized in that the diode 19 for preventing the chattering (Chatterring) phenomenon due to the reverse voltage generation of the capacitor 15 is characterized in that it is installed.

이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

도 2a에 도시한 바와 같이, 환풍기의 정상적인 작동시 배터리 전원이 릴레이(17)로 공급되어 릴레이(17)는 "OFF" 상태를 유지하게 되고, 순환 스위치(10) 또는 환풍 스위치(16)의 선택적인 "ON/OFF" 조작과 각 순환 접점(11)과 송풍 접점(13)의 접속/단락에 의해 모터(12)가 작동되면서 환풍기 도어가 열려지거나 닫혀지게 된다.As shown in FIG. 2A, during normal operation of the fan, battery power is supplied to the relay 17 so that the relay 17 remains in the "OFF" state, and selection of the circulation switch 10 or the ventilation switch 16 is performed. The fan door is opened or closed as the motor 12 is operated by the normal " ON / OFF " operation and the connection / shorting of each circulation contact 11 and the blow contact 13.

환풍기 도어의 개폐여부와 관련하여 차실내의 공기를 순환시키거나 실내외의 공기를 환풍시킬 수 있게 된다.In relation to whether the fan door is opened or closed, it is possible to circulate the air in the cabin or to vent the air outside the room.

도 2b에 도시한 바와 같이, 운전자가 차량 운행 후 환풍 스위치(16)를 "OFF" 하지 않고 그대로 방치한 경우, 차량 시동 정지와 동시에 배터리 전원이 차단되면 릴레이(17)가 "ON" 되고, 이때부터 상시 배터리 전원이 환풍모드로 인해 접속되어 있던 순환 접점(11)을 통해 모터(12)로 공급되고, 모터(12)의 작동에 의해 환풍기 도어가 닫혀지게 된다.As shown in FIG. 2B, when the driver is left as it is without turning off the ventilation switch 16 after the vehicle is driven, the relay 17 is turned “ON” when the battery power is cut off at the same time as the vehicle is stopped. Since the battery power is always supplied to the motor 12 through the circulation contact 11 which is connected due to the ventilation mode, the ventilator door is closed by the operation of the motor 12.

이때의 모터(12)는 1/2 회전 후 접점이 바뀌면서 정지되고, 순환 접점(11)은 떨어지고 송풍 접점(13)은 붙게 된다.At this time, the motor 12 is stopped by turning the contact after 1/2 rotation, the circulation contact 11 is dropped and the blower contact 13 is attached.

이때, 모터(12) 내의 콘덴서(15)에서 방전전압이 방출되어 릴레이(17)측으로 역전압이 유기되면서 채터링 현상이 발생할 수 있는데, 이러한 현상은 릴레이(17)측의 회로상에 설치되어 있는 다이오드(19)에 의해 방지될 수 있게 된다.At this time, the discharge voltage is discharged from the condenser 15 in the motor 12, the reverse voltage is induced to the relay 17 side, and a chattering phenomenon may occur, which is provided on the circuit on the relay 17 side. It can be prevented by the diode 19.

이상에서와 같이 본 발명은 차량 운행 후 환풍 스위치를 "OFF" 하지 않고 그대로 방치한 경우에도 환풍기 도어를 자동으로 닫을 수 있는 수단을 제공함으로써, 환풍기 도어를 통한 빗물이나 먼지 등의 유입을 차단할 수 있으며, 이에 따라 차량의 청결상태를 유지할 수 있고 운전자 편의성을 향상시킬 수 있는 효과가 있는 것이다.As described above, the present invention provides a means for automatically closing the ventilator door even when the vehicle is left as it is without turning off the vent switch, thereby preventing rain or dust from entering through the ventilator door. Accordingly, there is an effect that can maintain the clean state of the vehicle and improve driver convenience.
