Here, the cooling fan driving motors M1 and M2 are for driving the cooling fan for the condenser and the cooling fan for the radiator.
이와 같은 구성된 종래 엔진 냉각팬의 속도제어장치의 동작을 설명하면 다음과 같다.Referring to the operation of the speed control device of the conventional engine cooling fan configured as described above are as follows.
즉, 먼저 시동이 걸린 상태[즉, 이그니션 스위치(SW1)가 온상태]에서 에어콘이 동작하지 않는 경우[즉, 에어콘 스위치(SW3)가 오프상태인 경우]에는 냉각수의 온도가 제1소정온도(예컨대 96°C) 미만이면 냉각팬구동모터(M1, M2)는 작동되지 않고, 냉각수의 온도가 제1소정온도(예컨대 96°C)로 되면 상기 온도스위치(SW2)가 온상태로 되어 배터리전원(B)으로부터 저항(R1, R1)의 병렬회로를 매개로 냉각팬구동모터(M1, M2)로 전류가 흐르게 되므로 이 냉각팬구동모터(M1, M2)가 비교적 저속으로 구동됨에 따라 라디에이터 및 콘덴서용 냉각팬이 비교적 저속으로 회전하여 냉각기능을 수행하게 된다. 그후 냉각수의 온도가 계속 상승하여 제2소정온도(예컨대 102°C)로 되면 상기 엔진제어부(ECM)의 제1단자(C1)가 접지레벨로 되어 상기 배터리 전원(B)으로부터 릴레이(RE2)의 코일로 전류가 흐르므로 릴레이(RE2)의 접점을 온상태로 되고, 그에 따라 상기 배터리전원(B)으로부터 릴레이(RE2)의 접점을 매개로 냉각팬구동모터(M1, M2)로 전류가 흐르게 되어 이 냉각팬구동모터(M1, M2)가 비교적 고속으로 구동되므로 라디에이터 및 콘덴서용 냉각팬이 비교적 고속으로 회전하여 냉각기능을 수행하게 된다.That is, when the air conditioner does not operate in the state where the start-up is started (that is, the ignition switch SW1 is on) (that is, when the air conditioner switch SW3 is off), the temperature of the coolant is the first predetermined temperature ( For example, when the temperature is lower than 96 ° C, the cooling fan drive motors M1 and M2 are not operated. When the temperature of the cooling water reaches the first predetermined temperature (eg, 96 ° C), the temperature switch SW2 is turned on to turn on the battery power. (B Current flows to the cooling fan driving motors M1 and M2 through the parallel circuit of resistors R1 and R1, so that the cooling fan driving motors M1 and M2 are driven at a relatively low speed. The fan rotates at a relatively low speed to perform the cooling function. After that, when the temperature of the coolant continues to rise and reaches a second predetermined temperature (eg, 102 ° C.), the first terminal C1 of the engine control unit ECM becomes the ground level, and the battery power B Since the current flows from the coil to the coil of the relay RE2, the contact point of the relay RE2 is turned on, and thus the battery power source B Current flows to the cooling fan driving motors M1 and M2 through the contact of the relay RE2, so that the cooling fan driving motors M1 and M2 are driven at a relatively high speed, so that the cooling fan for the radiator and condenser is relatively high. It rotates to perform cooling function.
다음으로 시동이 걸린 상태에서 에어콘이 동작하는 경우 [즉, 에어콘 스위치(SW3)가 온상태인 경우]에는 배터리전원(B)로부터 릴레이(RE1)의 코일로 전류가 흘러서 릴레이(RE1)의 접점이 온 상태로 되므로 냉각수의 온도가 제1소정온도(예컨대 96°C) 미만이더라도 배터리전원(B)으로부터 릴레이(RE1)의 접점과 저항(R1, R1)의 병렬회로를 매개로 냉객팬구동모터(M1, M2)로 전류가 흐르게 되고 그에 따라 냉각팬구동모터(M1, M2)가 비교적 저속으로 구동되게 된다. 그후 에어콘에 과부하가 걸리게 되면 팬회전스위치(SW4)가 온상태로 되어 상기 배터리전원(B)으로부터 릴레이(RE2)의 코일을 매개로 엔진제어부(ECM)의 제2단자(C9)로 전류가 흐르므로 릴레이(RE2)의 접점이 온상태로 되고, 그에 따라 상기 배터리전원(B)으로부터 릴레이(RE2)의 단자를 매개로 냉각팬구동모터(M1, M2)로 전류가 흐르게 되어 이 냉객팬구동모터(M1, M2)가 비교적 고속으로 구동되게 한다.Next, when the air conditioner operates while the engine is started [that is, when the air conditioner switch (SW3) is on], the battery power (B Current flows from the coil to the coil of the relay RE1 so that the contact point of the relay RE1 is turned on, even if the temperature of the coolant is lower than the first predetermined temperature (eg, 96 ° C). ) Flows through the contact circuit of the relay RE1 and the parallel circuit of the resistors R1 and R1 to the cooler fan drive motors M1 and M2, so that the cooling fan drive motors M1 and M2 are relatively low speed. Will be driven. After that, when the air conditioner is overloaded, the fan rotation switch SW4 is turned on and the battery power B ), The current flows to the second terminal C9 of the engine control unit ECM through the coil of the relay RE2, so that the contact point of the relay RE2 is turned on, so that the battery power source B The current flows to the cooling fan driving motors M1 and M2 through the terminal of the relay RE2 through the terminal of the relay RE2 so that the cooling fan driving motors M1 and M2 are driven at a relatively high speed.
이와같이 종래 엔진 냉각팬의 속도제어장치에서는 냉각팬의 속도를 저항을 이용하여 제어하도록 되어 있는데, 저항을 사용함에 따라 배터리전원의 소모가 크고 저항에 의한 제조단가가 상승된다는 문제가 있다.As described above, in the speed control device of the conventional engine cooling fan, the speed of the cooling fan is controlled by using a resistor, but there is a problem that the consumption of battery power is increased and the manufacturing cost due to the resistance is increased by using the resistor.
이에 본 고안은 상기한 사정을 감안하여 이루어진 것으로, 콘덴서용 냉각팬과 라디에이터용 냉각팬의 고속제어시 각각의 냉각팬구동모터가 서로 병렬접속되도록 하여 냉각팬의 고속제어를 행하는 한편 엔진냉각팬의 저속제어시 각각의 냉각팬구동모터가 서로 직렬접속되도록 하여 냉각팬의 저속제어를 행하도록 함으로써 배터리전원을 소모시키지 않으면서도 제조단가를 증가시키지 않을 수 있도록 된 엔진 냉각팬의 속도제어장치를 제공하고자함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described circumstances. In the high speed control of the condenser cooling fan and the radiator cooling fan, the cooling fan driving motors are connected in parallel to each other to perform high speed control of the cooling fan. In order to provide a speed control device for an engine cooling fan, the cooling fan driving motors are connected to each other in series at a low speed control to perform low speed control of the cooling fan so that the manufacturing cost can not be increased without consuming battery power. The purpose is to.

이하, 상기와 같이 구성된 본 고안에 대해 제2도를 참조하여 상세히 설명된다.Hereinafter, the present invention constructed as described above will be described in detail with reference to FIG.
먼저, 시동이 걸린 상태[이그니션 스위치(SW1)가 온상태]에서 에어콘이 동작하지 않은 경우[즉, 에어콘 스위치(SW3)가 오프상태인 경우]에는 냉각수의 온도가 제1소정온도(예컨대 96°C) 미만이면 냉각팬구동모터(M1, M2)는 작동되지 않고, 냉각수의 온도가 제1소정온도(예컨대 96°C))로 되면 상기 온도스위치(SW2)가 온상태로 되어 배터리전원(B)으로부터 릴레이(RE4)의 코일로 전류가 흘려서 릴레이(RE4)의 접점이 온상태로 되어 배터리전원(B)으로부터 릴레이(RE4)와 냉각팬구동모터(M1), 릴레이(RE5)의 접점(c, a) 및 냉각팬구동모터(M2)를 매개로 접지로 이어지는 전류통로가 형성되므로 상기 냉각팬구동모터(M1, M2)가 직렬연결되어 냉각팬구동모터(M1, M2) 자체의 저항치에 의해 냉각팬구동모터(M1, M2)에 걸리는 전압이 분할되고, 그에 따라 냉각팬구동모터(M1, M2)가 비교적 저속으로 구동됨에 따라 라디에이터 및 콘덴서용 냉각팬이 비교적 저속으로 회전하여 냉각기능을 수행하게 된다. 그후 냉각수의 온도가 계속 상승하여 제2소정온도(예컨대 102°C))로 되면 상기 엔진제어부(ECM)의 제1단자(C1)가 접지레벨로 되어 상기 배터리전원(B)으로부터 릴레이(RE3, RE5)의 코일로 전류가 흐르므로 릴레이(RE3)의 접점이 온상태로 됨과 동시에 릴레이(RE5)의 접점(c, b)가 연결되고, 그에 따라 상기 배터리전원(B)으로부터 릴레이(RE3)의 접점과 냉각팬구동모터(M2)을 매개로 접지로 이어지는 전류통로가 형성됨과 동시에 상기 배터리전원(B)으로부터 릴레이(RE4)의 접점과 냉각팬구동모터(M1) 및 릴레이(R35)의 접점(c, b)을 매개로 접지로 이어지는 전류통로가 형성되게 된다. 따라서 상기 냉각팬구동모터(M1, M2)가 각각 배터리전원(B)과 병렬연결되어 냉각팬구동모터(M1, M2)가 비교적 고속으로 구동됨에 따라 라디에이터 및 콘덴서용 냉각팬이 비교적 고속으로 회전하여 냉각기능을 수행하게 된다.First, when the air conditioner is not operated in the state of starting (the ignition switch SW1 is on) (that is, when the air conditioner switch SW3 is in the off state), the temperature of the coolant is the first predetermined temperature (eg, 96 °). If less than C), the cooling fan driving motors M1 and M2 are not operated. When the temperature of the cooling water reaches the first predetermined temperature (eg, 96 ° C), the temperature switch SW2 is turned on to turn on the battery power (B). Current flows from the coil to the coil of the relay RE4 so that the contact of the relay RE4 is turned on, Since the current path leading to the ground is formed from the relay (RE4) and the cooling fan drive motor (M1), the relay (RE5) of the contact (c, a) and the cooling fan drive motor (M2) through the cooling fan drive motor The voltages applied to the cooling fan driving motors M1 and M2 are divided by the resistance values of the cooling fan driving motors M1 and M2 itself, and thus the cooling fan driving motors M1 and M2 are connected in series. As the relatively low speed is driven, the cooling fan for the radiator and the condenser rotates at a relatively low speed to perform a cooling function. After that, when the temperature of the coolant continues to rise and reaches a second predetermined temperature (eg, 102 ° C.), the first terminal C1 of the engine control unit ECM becomes the ground level, and the battery power source B Current flows from the coil to the coils of the relays RE3 and RE5, so that the contacts of the relays RE3 are turned on and at the same time, the contacts c and b of the relays RE5 are connected. The current path leading to the ground is formed through the contact point of the relay RE3 and the cooling fan drive motor M2, and at the same time the battery power source B The current path leading to the ground is formed through the contact of the relay (RE4) and the contact (c, b) of the cooling fan drive motor (M1) and the relay (R35). Therefore, the cooling fan driving motors (M1, M2) are each battery power (B) ) And the cooling fan drive motors (M1, M2) are driven at a relatively high speed in parallel to the cooling fan for the radiator and condenser rotates at a relatively high speed to perform the cooling function.
다음으로 시동이 걸린 상태에서 에어콘이 동작하는 경우[즉, 에어콘 스위치(SW3)가 온상태인 경우]에는 배터리전원(B)으로부터 릴레이(RE4)의 코일로 전류가 흘러서 릴레이(RE4)의 접점이 온상태로 되므로 냉각수의 온도가 제1소정온도(예컨대 96°C) 미만인 때에도 배터리전원(B)으로부터 릴레이(RE4)의 접점과 냉각팬구동모터(M1), 릴레이(RE5)의 접점(a, c) 및 냉각팬구동모터(M2)로 이어지는 전류통로가 형성되어 냉각팬구동모터(M1, M2)가 비교적 저속으로 구동되게 된다. 그후 에어콘에 과부하가 걸리게 되면 팬회전스위치(SW4)가 온상태로 되어 상기 배터리전원(B)으로부터 릴레이(RE3, RE5)의 코일로 전류가 흐르므로 릴레이(RE3)의 접점이 온상태로 됨과 동시에 릴레이(RE5)의 접점(c, b)가 연결되고, 그에 따라 냉각팬구동모터(M1, M2)가 각각 배터리전원(B)과 병렬연결되어 냉각팬구동모터(M1, M2)가 비교적 고속으로 구동됨에 따라 라디에이터 및 콘덴서용 냉각팬이 비교적 고속으로 회전하여 냉각기능을 수행하게 된다.Next, when the air conditioner operates while the engine is started (that is, when the air conditioner switch SW3 is on), the battery power (B Current flows from the coil to the coil of the relay RE4 so that the contact point of the relay RE4 is turned on, even when the temperature of the coolant is less than the first predetermined temperature (eg, 96 ° C). ), A current path is formed from the relay RE4 to the contact point of the cooling fan drive motor M1, the relay RE5 to the contact points a and c and the cooling fan drive motor M2 to form the cooling fan drive motor M1, M2) is driven at a relatively low speed. After that, when the air conditioner is overloaded, the fan rotation switch SW4 is turned on and the battery power B Current flows from the coil to the coils of the relays RE3 and RE5, so that the contacts of the relays RE3 are turned on and at the same time, the contacts c and b of the relays RE5 are connected, and thus the cooling fan driving motor M1. , M2 are each battery power (B ) And the cooling fan drive motors (M1, M2) are driven at a relatively high speed in parallel to the cooling fan for the radiator and condenser rotates at a relatively high speed to perform the cooling function.
이상 설명한 바와 같이 본 고안에 따르면, 콘덴서용 냉각팬과 라디에이터용 냉각팬의 고속제어시 각각의 냉각팬구동모터가 서로 병렬접속되도록 하여 냉각팬의 고속제어를 행하는 한편 엔진냉각팬의 저속제어시 각각의 냉각팬구동모터가 서로 직렬접속되도록 하여 냉각팬의 저속제어를 행하도록 함으로써 배터리전원을 소모시키지 않으면서도 부품수 절감에 따른 제조공정을 간단화해서 제조단가를 증가시킬 수 있게 된다.As described above, according to the present invention, when the high speed control of the condenser cooling fan and the radiator cooling fan is performed, the respective cooling fan driving motors are connected in parallel to each other to perform the high speed control of the cooling fan while the low speed control of the engine cooling fan, respectively. By allowing the cooling fan drive motors to be connected in series with each other to perform low speed control of the cooling fan, the manufacturing cost can be increased by simplifying the manufacturing process due to the reduction of the number of parts without consuming battery power.
