본 고안은 카에어콘 조절장치에 관한 것으로, 하절기 카에어콘의 장시간 작동시에 차실내에 취침중인 탑승자에게 발생할 수 있는 질식사고를 방지하기 위하여 카에어콘의 작동시간을 설정할 수 있도록 한 카에어콘 조절장치에 관한 것이다.The present invention relates to a car air conditioner, and to a car air conditioner to set the operating time of the car air conditioner in order to prevent choking accidents that may occur to the occupants sleeping in the cabin during long hours of operation of the car air conditioner. It is about.

일반적인 카에어콘 조절장치의 구성을 보인 제1도를 참조하면, 차실의 에어콘조작패널에 배치된 풍량조절스위치(S1)에는 점화전원(IG+)이 인가되며 그 절환접점(a)은 풍량조절스위치(S1)가 온되면 단계별로 설치된 저항(R1,R2,R3)을 통해 블로워모터(M1)로 연결된다.Referring to FIG. 1 showing a general car air conditioner, the ignition power supply IG + is applied to the air volume control switch S1 disposed on the air conditioner control panel of the vehicle cabin, and the switching contact a is the air volume control switch. When S1) is turned on, it is connected to the blower motor M1 through the resistors R1, R2, and R3 installed in stages.

또한, 상기 풍량조절스위치(S1)에는 절환접점(a)에 연동되는 다른 접점(b)이 구비되어, 이 접점(b)이 에어콘스위치(S2)로 연결되고, 에어콘스위치(2)의 후단은 전자제어모듈(ECM)의 입력단에 연결되고, 전자제어모듈(ECM)의 출력단은 일측이 점화전원(IG+)에 연결된 릴레이(RY1)의 코일(f)에 연결되고, 베터리전원이 직결되는 릴레이(RY1)의 가동접점(g)의 후단은 냉매압축기(20)의 마그네틱클러치(21)로 연결되어 전기적 구성이 이루어진다.In addition, the air volume control switch (S1) is provided with another contact (b) interlocked with the switching contact (a), this contact (b) is connected to the air conditioner switch (S2), the rear end of the air conditioner switch (2) The output terminal of the electronic control module (ECM), the output terminal of the electronic control module (ECM) is connected to the coil (f) of the relay (RY1), one side of which is connected to the ignition power (IG +), the battery power is directly connected to the relay ( The rear end of the movable contact g of RY1 is connected to the magnetic clutch 21 of the refrigerant compressor 20 to make an electrical configuration.

이와 같이 구성된 종래의 카에어콘 조절장치는 풍량조절스위치(S1)를 켜면 블로워모터(M1)가 작동되어 상온의 공기를 차실로 송풍하게 되며, 풍량조절스위치(S1)를 켠 상태에서 에어콘스위치(S2)를 켜게 되면, 에어콘스위치(S2)를 통해 전자제어모듈(ECM)의 입력단으로 전류가 흐르게 된다.Conventional car air conditioner is configured as the blower motor (M1) when the air flow control switch (S1) is turned on to blow air at room temperature to the cabin, the air conditioner switch (S2) in the state turned on When turned on, current flows to the input terminal of the electronic control module (ECM) through the air conditioner switch (S2).

이에 따라 전자제어모듈(ECM)은 한편으로는 엔진회전을 보상하도록 점화계통을 제어하는 동시에 릴레이(RY1)를 통한 전류를 어스시켜 릴레리(RY1)의 가동접점(g)을 접속하게 된다.Accordingly, the electronic control module ECM, on the one hand, controls the ignition system to compensate for engine rotation, and at the same time, connects the movable contact g of the relay RY1 by grounding a current through the relay RY1.

이와같이 릴레이(RY1)의 가동접점(g)의 접속으로 인가되는 전원에 의해 마그네틱클러치(21)가 작동되어 냉매압축기(20)를 구동함으로써, 냉매를 압축순환시켜 냉각공기를 실내로 보내게 되어 여름철 쾌적한 차실환경을 제공하게 된다.In this way, the magnetic clutch 21 is operated by the power applied by the connection of the movable contact g of the relay RY1 to drive the refrigerant compressor 20, thereby compressing and circulating the refrigerant to send cooling air to the room. It will provide a comfortable cabin environment.

그러나, 상기한 카에어콘 조절장치는 풍량조절스위치 및 에어콘스위치가 기계적인 구조로 구성되어 인위적으로 스위치를 끄지 않는 한 에어콘의 작동을 중지시킬 수 없기 때문에 차내 취침시의 에어콘 사용시에는 질식사고의 위험이 발생하게 되는 문제점이 있었다.However, since the air conditioner and the air conditioner switch have a mechanical structure, the air conditioner cannot be stopped unless the switch is artificially turned off.Therefore, there is a risk of suffocation when using the air conditioner at bedtime. There was a problem that occurred.

본 고안은 상기한 바와같은 문제점을 해결하기 위해 착안된 것으로, 카에어콘의 작동을 탑승자의 조작에 의해 설정되어진 시간 경과후에는 자동으로 꺼지도록하여 차실에 취침중인 탑승자의 질식사고를 예방하려는 목적이 있는 것이다.The present invention has been conceived to solve the problems described above, the purpose of the car air conditioner to turn off automatically after the time set by the operation of the passengers to prevent the suffocation accident of the passengers in bed. It is.

이와같은 목적을 달성하기 위한 본 고안에 따르면, 차실에 구비된 에어콘스위치의 신호에 따라 엔진회전을 보상하는 전자제어모듈과, 상기 전자제어모듈의 출력신호에 의해 작동하여 전원을 인가하는 릴레이와, 상기 릴레이에 의해 전원이 공급되어 에어콘콤프레셔를 구동시키는 마그네틱클러치와, 상기 에어콘스위치로 작동전원을 인가하는 풍량조절스위치에 의해 조절되어 상기 에어콘콤프레셔의 작동에 의해 발생한 냉풍을 가변송풍하는 블로워모터로 구성된 카에어콘 조절장치에 있어서, 상기 전자제어모듈에서 출력되어 인버터를 통해 반전된 신호에 의해 작동되는 트랜지스터와, 설정된 시간동안 상기 트랜지스터의 턴온작동에 의해 상기 마그네틱클러치 및 상기 블로워모터를 통전시키는 타이머로 구성된 것을 특징으로 하는 카에어콘 조절장치가 제공된다.According to the present invention for achieving the above object, an electronic control module for compensating engine rotation according to the signal of the air conditioner switch provided in the vehicle compartment, a relay for operating the output signal of the electronic control module to apply power; It is composed of a magnetic clutch which is supplied with power by the relay to drive an air compressor, and a blower motor which is controlled by a flow rate control switch for applying operating power to the air conditioner switch to variably blow the cold air generated by the operation of the air compressor. A car air conditioner, comprising: a transistor output from the electronic control module and operated by a signal inverted through an inverter; and a timer for energizing the magnetic clutch and the blower motor by a turn-on operation of the transistor for a predetermined time. Car air conditioner characterized in that Value is provided.

이하, 본 고안의 바람직한 실시예를 도면을 참조하여 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

제2도에 도시한 바와 같이, 차실의 에어콘조작패널에 배치된 풍량조절스위치(S1)의 절환접점(a)은 단계별로 저항(R1,R2,R3)을 통해 블로워모터(M1)의 일단으로 연결되는 것은 종래의 것과 동일하나, 블로워모터(M1)의 타단은 접지로 직결되지 않고 타이머(T1)의 출력단에 연결된다.As shown in FIG. 2, the switching contact a of the air volume control switch S1 disposed in the air conditioner control panel of the vehicle compartment is stepwise through the resistors R1, R2, and R3 to one end of the blower motor M1. The connection is the same as the conventional one, but the other end of the blower motor M1 is connected to the output terminal of the timer T1 without being directly connected to ground.

또한, 상기 풍량조절스위치(S1)는 절환접점(a)에 연동되는 다른 접점(b)이 구비되어 이 접점(b)이 에어콘스위치(S2)로 연결되고, 에어콘스위치(S2)의 후단은 전자제어모듈(ECM)의 입력단에 연결되고, 전자제어모듈(ECM)의 출력단은 일측이 전원에 연결된 릴레이(RY1)의 코일(f)의 타단에 연결되고 릴레이(RY1)의 가동접점(g)의 후단은 냉매압축기(20)의 마그네틱클러치(21)의 일단으로 연결되는 것은 종래의 것과 동일하나, 마그네틱클러치(21)의 타단은 접지로 직결되지 않고 타이머(T1)의 출력단(d)에 연결된다.In addition, the air volume control switch (S1) is provided with another contact (b) interlocked with the switching contact (a), the contact (b) is connected to the air conditioner switch (S2), the rear end of the air conditioner switch (S2) It is connected to the input terminal of the control module (ECM), the output terminal of the electronic control module (ECM) is connected to the other end of the coil (f) of the relay (RY1), one side of which is connected to the power supply, and the movable contact (g) of the relay (RY1) The rear end is connected to one end of the magnetic clutch 21 of the refrigerant compressor 20 as in the related art, but the other end of the magnetic clutch 21 is connected to the output end d of the timer T1 without being directly connected to ground. .

또한, 전자에어모듈(ECM)과 릴레이(RY1)의 코일(f)의 접속점이 인버터(G1)의 입력단으로 접속되고, 인버터(G1)의 출력단은 트랜지스터(TR1)의 베이스측에 접속되고, 이 트랜지스터(TR1)의 컬렉터측은 전원으로, 그리고 에이터측은 타이머(T1)의 입력단으로 연결된다.In addition, the connection point of the electromagnetic air module ECM and the coil f of the relay RY1 is connected to the input terminal of the inverter G1, and the output terminal of the inverter G1 is connected to the base side of the transistor TR1. The collector side of transistor TR1 is connected to the power supply and the actor side to the input terminal of timer T1.

상기 타이머(T1)는 일단(c)에 접지전위가 연결되어 트랜지스터(TR1)가 턴온되어 하이레벨의 신호가 입력되면 두 출력단(d,e)으로 접지전위가 연결되다가 설정된 소정시간 경과후에는 접지전위의 연결된 상태가 차단되고, 다시 트랜지스터(TR1)의 에미터측에서 하이레벨의 신호가 입력되면 다시 접속상태로 되도록 구성된다.When the timer T1 is connected to the ground potential at one end (c) and the transistor TR1 is turned on to input a high level signal, the ground potential is connected to the two output terminals d and e. The connected state of the potential is cut off, and when a high level signal is input from the emitter side of the transistor TR1, the connected state is set again.

이와 같이 구성된 본 고안은 풍량조절스위치(S1)와 에어콘스위치(S2)를 켜면 저항(R1,R2,R3)을 통해 블로워모터(M1)의 일단에 전원이 인가되며, 전자제어모듈(ECM)에서 릴레이(RY1)의 코일(f)을 통전, 가동점점(g)을 작동시켜 마그네틱클러치(21)의 일단으로 전원을 인가함과 동시에 인버터(G1)를 통해 반전된 전위를 인가하여 트랜지스터(TR1)를 턴온시켜 타이머(T1)의 입력단에 하이레벨의 전위를 인가하게 된다.When the air flow control switch (S1) and the air conditioner switch (S2) are turned on, the present invention configured as described above is supplied with power to one end of the blower motor (M1) through the resistors (R1, R2, R3), in the electronic control module (ECM). The coil f of the relay RY1 is energized and the operating point g is operated to apply power to one end of the magnetic clutch 21 and to apply the inverted potential through the inverter G1 to supply the transistor TR1. Turn on to apply the high level potential to the input terminal of the timer T1.

이에 따라 타이머(T1)는 두 출력단으로 접지전위를 접속시켜 블로워모터(M1)와 마그네틱클러치(21)를 작동시킴으로써, 에어콘을 가동하여 차실내를 냉방하게 된다.Accordingly, the timer T1 connects the ground potential to two output terminals to operate the blower motor M1 and the magnetic clutch 21, thereby operating the air conditioner to cool the interior of the vehicle.

이와 같이 냉방하는 중 타이머(T1)에 조작된 설정시간에 도달하면 타이머(T1)는 두 출력단이 일단과 단락되어 출력단으로의 접지전위접속을 차단하게 된다.When the set time manipulated by the timer T1 is reached while cooling in this manner, the timer T1 shorts the two output terminals with one end and blocks the ground potential connection to the output terminal.

이에 따라 동작하던 냉매압축기(20)와 블로워모터(M1)는 작동이 정지하게 되므로 카에어콘은 작동을 중지하게 되는 것이다.Accordingly, since the refrigerant compressor 20 and the blower motor M1 that were operated are stopped, the car air conditioner is stopped.

이상에서 설명한 바와 같이 본 고안은 하절기 카에어콘의 작동시 탑승자의 조작에 의해 설정된 시간 후에는 자동으로 꺼지도록 하여 차실내에 취침중인 탑승자의 질식사고를 방지하는 효과가 있는 것이다.As described above, the present invention has an effect of preventing the suffocation of the occupant in bed in the cabin by automatically turning off after a time set by the operation of the occupant during the operation of the summer air conditioner.
