본 고안은 솔레노이드밸브 구동회로에 관한 것으로, 특히 가스를 사용하는 제품의 안전성에 적당하도록 한 것이다.The present invention relates to a solenoid valve driving circuit, in particular to be suitable for the safety of the product using the gas.
종래에는 제1도에 나타낸 바와 같이 점화기와 가스공급용인 솔레노이드 밸브를 구비한 가스기구에 있어서, 마이컴을 사용하여 이 마이컴의 내장된 프로그램에 의해 상기 밸브및 점화기의 구동을 제어토록 구성하였다.Conventionally, as shown in FIG. 1, in a gas appliance provided with an igniter and a solenoid valve for gas supply, a microcomputer is used to control the driving of the valve and the igniter by a built-in program of the microcomputer.
즉, 마이컴의 단자(0)에서 하이신호가 출력될 경우 트랜지스터(Q4)는 오프되고 이어 릴레이(RY3)도 오프되어 가스공급용인 솔레노이드 밸브(도시되지 않음)는 닫혀지게 되고 반대로 마이컴의 단자(L)에서 로우신호가 출력될 경우 트래지스터(Q4)는 온되고 이어 릴레이(RY3)도 온되므로 솔레노이드밸브는 열리게 된다.That is, when a high signal is output from the terminal 0 of the microcomputer, the transistor Q 4 is turned off, and then the relay RY 3 is also turned off to close the solenoid valve (not shown) for gas supply and, conversely, the terminal of the microcomputer. When the low signal is output at (L), the solenoid valve is opened because the transistor Q 4 is turned on and the relay RY 3 is also turned on.
또한, 마이컴의 단자(L)에서 하이신호가 출력될 경우 트랜지스터(Q3)는 오프되고 이어 릴레이(RY2)도 오프되어 점화기는 불꽃을 튀기지 않게 된다.In addition, when a high signal is output from the terminal L of the microcomputer, the transistor Q 3 is turned off and the relay RY 2 is also turned off so that the igniter does not splatter a spark.
반대로 로우신호가 출력될 경우에는 트랜지스터(Q3)가 온되고 이어 릴레이 (RY2)도 온되므로 점화기는 방전을 개시하게 된다.On the contrary, when the low signal is output, the transistor Q 3 is turned on and the relay RY 2 is also turned on, so that the igniter starts discharging.
그러나 상기 종래기술은 마이컴을 사용하므로써 상기 점화기 및 솔레노이드밸브 구동기능외에 여러가지 기능을 갖을수 있는 장점은 있으나 만약 마이컴의 사용이 상기 가스공급용인 솔레노이드밸브와 점화기의 구동만을 위해서라면 대부분의 마이컴단자가 사용되지 않으므로 인해 이에 따른 불필요한 원가상승 및 구성상의 문제점이 있었다.However, the conventional technology has the advantage of having various functions besides the igniter and solenoid valve driving function by using a microcomputer, but if the use of the microcomputer is solely for driving the solenoid valve and the igniter for gas supply, most of the microcomputer terminals are used. Because of this, there was an unnecessary cost rise and configuration problems accordingly.
또한 마이컴이 오동작을 할경우에는 안전사고가 발생할 수도 있는 문제점이 있었다.In addition, there was a problem that a safety accident may occur when the microcomputer malfunctions.
본 고안은 상기 문제점을 해소키위해 안출된 것으로 이를 해결하기 위한 수단으로서 마이컴대신 점화기가 방전되면 전압을 발생시키는 신호발생부와 이 신호발생부의 출력을 정류시키는 정류부와 이 정류부의 출력과 기준전압 레벨치를 비교하여 이상 및 이하에서 각각 솔레노이드밸브를 개폐시키도록 릴레이 구동신호를 출력하는 레벨비교부를 포함하여 구성하므로써 점화기와 솔레노이드밸브가 결합구동될 수 있는 솔레노이드밸브 구동회로를 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems. As a means for solving the above problems, a signal generator for generating a voltage when the igniter is discharged instead of a microcomputer, a rectifier for rectifying the output of the signal generator, and an output and a reference voltage level of the rectifier. It is an object of the present invention to provide a solenoid valve driving circuit in which an igniter and a solenoid valve can be coupled and driven by including a level comparison unit for outputting a relay driving signal so as to open and close the solenoid valve in the above and below, respectively.
이를 첨부된 제2a도 내지 b도에 의거하여 상술하면 다음과 같다.Based on the attached 2a to b diagram as follows.
제2a도는 본 고안의 구성블럭도로서, 상기한 신호발생부(1)와 정류부(2) 및 레벨비교부(3)를 솔레노이드 밸브 구동용인 통상의 릴레이부(4)에 순차적으로 접속하여 구성함을 나타낸 것이다.2a is a block diagram of the present invention, in which the signal generator 1, the rectifier 2, and the level comparator 3 are sequentially connected to a normal relay 4 for driving a solenoid valve. It is shown.
제2b도는 a도에 따른 본 고안의 일실시예를 나타내는 상세회로도로서 신호발생부(1)는 트랜스(T1)를 사용하여 구성하고 정류부(2)는 브릿지 다이오우드(BD1)및 커패시터(C1)로 구성하며 레벨비교부(3)는 역위상의 2개 연산증폭기(IC1)(IC2)로 구성하고 이 레벨비교부(3)의 출력신호는 솔레노이드밸브의 구동을 위한 릴레이부(4)의 릴레이 구동용 트랜지스터(Q1)(Q2)에 인가되도록 접속하여 구성함을 나타낸 것이다.The signal generating unit 1 is configured using a transformer (T 1) and the rectifying section (2) as a detailed circuit diagram illustrating one embodiment of the subject innovation according turning on a Figure 2b is a bridge diode (BD 1) and a capacitor (C 1 ) and the level comparator 3 consists of two operational amplifiers (IC 1 ) (IC 2 ) in the reverse phase. The output signal of the level comparator 3 is a relay part for driving the solenoid valve. 4 is connected to be applied to the relay driving transistor Q 1 and Q 2 .
이와 같이 구성된 본 고안은 먼저 점화기(도시되지 않음)가 방전을 개시하면 거기에 부착된 신호발생부(1)인 트랜스(T1)의 출력에는 AC 전압이 발생하게 되고 발생된 AC 전압은 정류부(2)인 브릿지 다이오우드(BD1)를 통해 정류된 후 커패시터(C1)에 충전되기 시작한다.According to the present invention configured as described above, when an igniter (not shown) starts discharging, an AC voltage is generated at the output of the transformer T 1 , which is a signal generator 1 attached thereto, and the generated AC voltage is a rectifier ( After rectifying through the bridge diode BD 1 , which is 2), it begins to charge the capacitor C 1 .
이어 커패시터(C1)에 충전된 전압은 레벨비교부(3)의 연산증폭기(IC1)(IC2)의 반전(-), 비반전(+)단자에 각각 동시에 입력되고 이 연산증폭기(IC1)(IC2)는 전원 (Vcc)으로부터 저항(R2)(R3)(R6)에 의해 분압되어 비반전(+), 반전(-)단자에 인가되어 있는 기준전압과 이 충전전압과를 비교하게 된다.Subsequently, the voltage charged in the capacitor C 1 is simultaneously input to the inverting (-) and non-inverting (+) terminals of the operational amplifier IC 1 (IC 2 ) of the level comparison unit 3, respectively. 1 ) (IC 2 ) is divided by the resistors R 2 (R 3 ) (R 6 ) from the power supply (Vcc) and applied to the non-inverting (+) and inverting (-) terminals. Will be compared with
즉, 일정시간이 경과된 후에 커패시터(C1)에 충전된 전압이 기준전압 보다 높아질 경우 연산증폭기(IC1)(IC2)는 각각 로우와 하이신호를 출력하게 되고 이어 릴레이부(4)의 트랜지스터(Q1)(Q3)는 모두 온되므로써 릴레이(RY1)/솔레노이드밸브(도시되지 않음)는 순차적으로 온되어 가스가 공급된다.That is, if a voltage charged in the capacitor C 1 becomes higher than the reference voltage after a certain time has elapsed, the operational amplifier IC 1 IC 2 outputs a low and a high signal, respectively. Since the transistors Q 1 and Q 3 are all turned on, the relay RY 1 / solenoid valve (not shown) is sequentially turned on to supply gas.
여기서 점화기가 방전을 하지 않으면 트랜스(T1)에는 전압이 발생되지 않아 솔레노이드밸브는 열리지 않고 또한 릴레이부(4)의 트랜지스터(Q1)(Q2)중 어느 하나라도 온되지 않으면 솔레노이드밸브는 열리지 않게 된다.Here, if the igniter does not discharge, no voltage is generated in the transformer (T 1 ) so that the solenoid valve does not open, and the solenoid valve does not open unless any one of the transistors (Q 1 ) (Q 2 ) of the relay unit 4 is turned on. Will not.
이상과 같이 본 고안은 점화기가 구동되기 전에는 솔레노이드밸브가 열리지 않게 되어 있어서 안전사고를 방지할 수 있는 효과가 있을 뿐만 아니라 프로그램 과정을 거치는 마이컴을 사용할 필요가 없으므로 제품공정의 신속화 및 원가절감을 꾀할 수 있는 효과가 있다.As described above, the present invention is not only open the solenoid valve until the igniter is driven, it is effective in preventing safety accidents, and it is not necessary to use the microcomputer that goes through the program process, so that the product process can be accelerated and the cost can be reduced. It has an effect.
