본 발명은 버스 에어컨 덕트내의 풍압을 감지하여 에어컨을 온/오프시키기 위한 장치에 관한 것으로, 에어컨 덕트내부의 풍압에 따라 개폐되는 보조 토출구 리드, 상기 보조 토출구 리드의 개폐에 따라 에어컨을 온/오프시키는 풍압 감지 온/오프 센서 장치, 및 에어컨 덕트내부의 풍압에 따라 상기 보조 토출구 리드를 닫는 보조 토출구 리드 스프링을 포함한다.The present invention relates to an apparatus for sensing an air pressure in a bus air conditioner duct to turn on / off the air conditioner. A wind pressure sensing on / off sensor device, and an auxiliary discharge port lead spring for closing the auxiliary discharge port lead in accordance with the wind pressure in the air conditioner duct.

이하, 도면을 참조하면서 본 발명을 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail, referring drawings.

도 2는 본 발명에 따른 버스 에어컨 덕트의 요부 단면도이다.2 is a sectional view of principal parts of a bus air conditioner duct according to the present invention;

에어컨이 구동되어 버스 실내를 냉각하고, 한기를 느낀 승객이 메인 토출구(11)를 닫으면, 보조 토출구 리드(22)도 닫혀 있어 에어컨 덕트(1) 내부의 풍압이 증가된다.When the air conditioner is driven to cool the bus interior and the passenger feeling the cold closes the main discharge port 11, the auxiliary discharge port lead 22 is also closed, so that the air pressure inside the air conditioner duct 1 is increased.

증가된 풍압이 일정 압력 이상으로 되면, 풍압에 의하여 보조 토출구 리드(22)가 오픈된다.When the increased wind pressure becomes more than a predetermined pressure, the auxiliary discharge port lead 22 is opened by the wind pressure.

보조 토출구 리드(22)가 오픈되면 온/오프 감지 센서(21)는 오프되고, 모든 온/오프 감지 센서(21)가 오프되면 풍압 감지 온/오프 센서 장치(도 3 참조:3)에 의하여 에어컨이 정지된다.When the auxiliary discharge port lead 22 is opened, the on / off detection sensor 21 is turned off, and when all the on / off detection sensors 21 are turned off, the air conditioner is turned on by the air pressure detection on / off sensor device (see FIG. 3: 3). Is stopped.

운전자가 에어컨을 정지시키지 않으면 에어컨 덕트(1) 내부의 풍압이 감소되고, 감소된 풍압이 일정 압력 이하로 되면 보조 토출구 리드 스프링(23)에 의하여 보조 토출구 리드(22)는 닫히게 된다.If the driver does not stop the air conditioner, the air pressure inside the air conditioner duct 1 decreases, and when the reduced wind pressure becomes less than a predetermined pressure, the auxiliary discharge port lead 22 is closed by the auxiliary discharge port lead spring 23.

보조 토출구 리드(22)가 닫히게 됨으로써, 온/오프 감지 센서(21)는 온되고, 일정 시간이 경과된 후에 풍압 감지 온/오프 센서 장치(도 3 참조:3)에 의하여 에어컨이 구동된다.As the auxiliary discharge port lid 22 is closed, the on / off detection sensor 21 is turned on and the air conditioner is driven by the wind pressure detection on / off sensor device (see Fig. 3) after a predetermined time has elapsed.

이 때, 온/오프 감지 센서(21)는 접촉식 또는 비접촉식 스위치를 사용한다.At this time, the on / off detection sensor 21 uses a contact or non-contact switch.

도 3은 본 발명에 따른 풍압 감지 온/오프 센서 장치를 보여주는 도면이다.3 is a view showing a wind pressure detection on / off sensor device according to the present invention.

온/오프 감지 센서(21)는 도 3에 나타낸 바와 같이 병렬로 연결되어, 모든 온/오프 감지 센서(21)가 오프되었을 때, 전자 제어 장치(ECU:31)는 에어컨 모터(33)를 정지시키기 위한 제어 신호를 출력한다.The on / off detection sensor 21 is connected in parallel as shown in FIG. 3 so that when all the on / off detection sensors 21 are off, the electronic control unit (ECU) 31 stops the air conditioner motor 33. Outputs a control signal for

전자 제어 장치(31)로부터 출력된 제어 신호에 의하여, 에어컨 구동 릴레이(32)가 오프되어 에어컨 모터(33)는 정지된다.By the control signal output from the electronic control apparatus 31, the air conditioner drive relay 32 is turned off and the air conditioner motor 33 is stopped.

운전자가 에어컨을 끄지 않고, 즉 에어컨 스위치(34)가 오프되지 않고 온/오프 감지 센서(21)가 1개 이상 온되면, 전자 제어 장치(31)는 일정 시간이 경과된 후에 에어컨 모터(33)를 구동시키기 위한 제어 신호를 출력하고, 출력된 제어 신호에 의해 에어컨 구동 릴레이(32)가 온되어 에어컨이 구동된다.If the driver does not turn off the air conditioner, that is, the air conditioner switch 34 is not turned off and one or more on / off detection sensors 21 are turned on, the electronic control device 31 performs the air conditioner motor 33 after a predetermined time has elapsed. Outputs a control signal for driving the air conditioner, the air conditioner driving relay 32 is turned on by the output control signal to drive the air conditioner.

도 4는 본 발명에 따른 에어컨 덕트내의 풍압을 감지하여 에어컨을 온/오프시키기 위한 장치의 동작을 보여주는 플로우챠트이다.Figure 4 is a flow chart showing the operation of the device for turning on / off the air conditioner by detecting the wind pressure in the air conditioner duct according to the present invention.

에어컨이 구동되어(S1) 버스 실내를 냉각하고, 단계 S2에서는 온/오프 감지 센서가 1개 이상 온될 경우에는 에어컨을 계속 구동시키고, 모든 온/오프 감지 센서가 오프될 경우에는 에어컨 구동 릴레이를 오프시켜(S3), 에어컨을 정지시킨다(S4).The air conditioner is driven (S1) to cool the bus room, and in step S2, the air conditioner is continuously driven when at least one on / off detection sensor is turned on, and the air conditioner driving relay is turned off when all the on / off detection sensors are turned off. (S3), the air conditioner is stopped (S4).

단계 S5에서 운전자가 수동으로 에어컨을 정지시키지 않을 경우, 단계 S6에서는 온/오프 감지 센서가 1개 이상 온되면, 일정 시간이 경과된 후(S7) 에어컨 구동 릴레이가 온된다(S8).If the driver does not stop the air conditioner manually in step S5, if at least one on / off detection sensor is turned on in step S6, after a predetermined time has elapsed (S7), the air conditioner driving relay is turned on (S8).

단계 S8에서 에어컨 구동 릴레이가 온되어 에어컨이 다시 구동되고(S1), 상기 단계를 반복하게 된다.In step S8, the air conditioner driving relay is turned on so that the air conditioner is driven again (S1), and the above steps are repeated.

단계 S6에서 온/오프 감지 센서가 모두 오프이면, 에어컨은 계속 정지된다.If the on / off detection sensors are all off in step S6, the air conditioner continues to stop.

상기된 바와 같은 본 발명에 따른 에어컨 덕트내의 풍압을 감지하여 에어컨을 온/오프시키기 위한 장치는 불필요한 에어컨 작동 동작으로 엔진 힘의 효율을 높이고, 운전자의 실내 온도 체크의 필요성이 줄어들어 운전에 전념할 수 있으며, 승객 개인의 체질에 맞게 에어컨이 온/오프되어 쾌적한 여행이 될 수 있다. 또한, 불필요한 에어컨 압축기의 구동이 없어져 소음 저감 및 차량 운전 중 연료 소비가 줄게 된다.The device for sensing the air pressure in the air conditioner duct according to the present invention as described above to increase the efficiency of the engine power by unnecessary air conditioning operation operation, the need to check the room temperature of the driver can be dedicated to driving In addition, the air conditioner can be turned on and off according to the personal constitution of the passenger so that it can be a pleasant trip. In addition, unnecessary air conditioning compressors are driven to reduce noise and reduce fuel consumption during vehicle operation.
