본 고안은 가스기기의 가스누설 차단 안전장치에 관한 것으로, 특히 가스센서를 사용한 전자회로로 가스누설을 감지함과 동시에 밸브를 차단시키고 스위치 작동시 지연시간 없이 즉시기기를 동작시킬 수 있도록 한 것이다.The present invention relates to a gas leakage blocking safety device of a gas machine, and in particular, an electronic circuit using a gas sensor detects a gas leak and at the same time shuts off a valve and immediately operates the machine without a delay when the switch is operated.

종래에는 가스기기의 가스누설 차단시 더모 커플(Themo Couple)을 사용하여 차단하였으나 더모 커플이 일정 열을 기전하여 마그네틱 파우어 유니트(Magnetic Power Unit)를 구동하기 위해서는 더모 커플이 가열되기 까지 인위적인 힘을 계속 가해 주어야 했다.Conventionally, when the gas leakage of the gas appliance is blocked by using a thermo couple, the thermo couple couples a certain amount of heat to drive the magnetic power unit, so that the artificial force continues until the thermo couple is heated. I had to add it.

즉, 제2도에 도시된 바와같이 열을 받아 기전력을 발생하는 더모커플(D)과 그 기전력으로 마그네틱 코일을 구동시켜 밸브를 온, 오프시키는 마그네틱 파우어 유니트(E)로 구성된 종래의 장치의 더모커플(D)이 일정열을 받아 기전력이 발생되면 더모커플(D)의 G부분과 마그네틱 파우어 유니트(E)의 H부분이 연동되도록 되어 있어 기전력이 전달되므로 마그네틱 파우어 유니트(E) 내부의 코일(L)에 전류가 흘러 전자석이 되고 밸브(M)를 개방새켜 가스를 유출시키며, 불이 꺼져 일정한 열이 더모커플(D)에 감지되지 않으면 기전력을 상실하여 밸브(M)가 스프링(N)의 힘에 의해 가스를 차단하게 되는 것으로, 더모커플(D)이 가열되기까지 지연시간이 오래 걸리는등 사용상의 불편함이 있었다.That is, as shown in FIG. 2, a thermocouple of a conventional apparatus including a thermocouple (D) that receives heat and generates an electromotive force, and a magnetic powder unit (E) that drives a magnetic coil with the electromotive force to turn on and off a valve. When the couple (D) receives a certain heat and generates an electromotive force, the G portion of the thermocouple (D) and the H portion of the magnetic powder unit (E) are interlocked so that the electromotive force is transmitted, so that the coil inside the magnetic powder unit (E) ( The current flows to L) and becomes an electromagnet, and the valve M is opened and the gas is leaked.If the heat is turned off and constant heat is not sensed by the thermocouple D, the electromotive force is lost and the valve M becomes the spring N. By blocking the gas by force, there was an inconvenience in use such as a long delay time before the thermocouple D was heated.

본 고안은 이와같은 종래의 결점을 감안하여 안출한 것으로, 가스센서를 사용한 IC회로를 마그네틱 파우어 유니트에 연결시켜 즉시 기기를 구동시킴을 물론 가스누설 감지와 차단을 할수 있도록 한 것인바, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above-mentioned drawbacks, and the IC circuit using the gas sensor can be connected to the magnetic power unit to immediately operate the device and to detect and block gas leakage. Referring to the drawings in detail as follows.

제1도에 도시된 바와같이 스위치(S/W)에 저항(R1)과 가스센서(S)의 접점(A)을 통하여 비교기(IC)의 비반전단자(+)를, 저항(R2)(R3)의 접점(B)에 반전단자(-)를 접속하고 비교기(IC)의 출력단에 저항(R4)을 통하여 JK플립플롭(FF)의 클리어단자(C)를 접속하며 그의 출력단자(Q)를 저항(R6)을 통하여 통상의 마그네틱 파우어 유니트(E)의 H부분에 연결하여 구성된 것이다.As shown in FIG. 1 , the non-inverting terminal (+) of the comparator IC is connected to the switch S / W through the contact A of the resistor R 1 and the gas sensor S, and the resistor R 2. Connect the inverting terminal (-) to the contact point (B) of (R 3 ), connect the clear terminal (C) of the JK flip-flop (FF) through the resistor (R 4 ) to the output terminal of the comparator (IC), and its output. The terminal Q is connected to the H portion of the conventional magnetic powder unit E through the resistor R 6 .

도면중 미설명 부호 Vcc는 전원, R5는 저항, L은 코일 N은 스프링, M은 밸브이다.In the figure, reference numeral Vcc denotes a power supply, R 5 denotes a resistor, L denotes a coil N denotes a spring, and M denotes a valve.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

스위치(S/W)가 온되면 초기 상태에서는 A점 전위가 B점의 전위보다 높게 설정되어 있으므로 비교기(IC)의 출력은 하이레벨이 최고 저항(R4)을 통하여 JK플립플롭(FF)의 클리어단자(C)에 인가된다.When the switch S / W is turned on, in the initial state, the potential of the point A is set to be higher than the potential of the point B, so that the output of the comparator IC has a high level through the highest resistance R 4 of the JK flip-flop FF. It is applied to the clear terminal (C).

이때 JK플립플롭(FF)의 단저(J)에는 하이레벨, 단자(K)에는 로우레벨이 항상 입력되므로 JK플립플롭(FF)의 출력단자 (Q)에서는 하이레벨이 출력되고 저항(R6)을 통하여 마그네틱 파우어 유니트(E)의 H부분에 인가되어 코일(L)에 자장이 발생되게 하므로 밸브(M)은 온된다.At this time, since the high level is always input to the bottom J of the JK flip-flop FF, and the low level is input to the terminal K, the high level is output from the output terminal Q of the JK flip-flop FF, and the resistor R 6 is applied. The magnetic field is generated in the coil L by being applied to the H portion of the magnetic powder unit E through the valve M, so that the valve M is turned on.

이러한 상태에서 불이 꺼지고 가스가 누설되면 가스감지기시 저항치가 감소되는 가스센서(S)에 의하여 가스가 감지되어 A점의 전위가 B점의 전위보다 낮아진다.In this state, when the light is turned off and the gas is leaked, the gas is sensed by the gas sensor S which decreases the resistance when detecting the gas, so that the potential at the point A is lower than the potential at the point B.

따라서 비교기(IC)의 출력은 로우레벨이 되고, 저항(R4)을 통한 로우레벨이 JK플립플롭(FF)의 클리어 단자(C)에 인가되므로 JK플립플롭(FF)의 출력이 클리어되어 로우레벨이 되는 것이며 마그네틱 파우어유니트(E)의 H부분에 로우레벨이 인가되므로 코일(L)은 기전력을 잃게 되고 그동안 개방되어 있던 밸브(M)은 스프링(N)의 힘에 의해 폐쇄되므로 가스의 누설을 차단할 수 있게 되는 것이다.Therefore, the output of the comparator IC becomes a low level, and since the low level through the resistor R 4 is applied to the clear terminal C of the JK flip-flop FF, the output of the JK flip-flop FF is cleared and low. Since the low level is applied to the H portion of the magnetic powder unit E, the coil L loses electromotive force, and the valve M, which has been open, is closed by the force of the spring N, so the gas leaks. Will be able to block.

또한, 밸브(M)가 차단되면 가스센서(S)의 저항치는 다시 증가해서 A점의 전위가 B점의 전위보다 높아져 비교기(IC)의 출력이 하이레벨이 되어도 JK플립플롭(FF)의 출력은 계속 로우레벨을 유지하게 된다.In addition, when the valve M is shut off, the resistance of the gas sensor S increases again, and the potential of the point A becomes higher than the potential of the point B, so that the output of the JK flip-flop FF even when the output of the comparator IC becomes high level. Will remain low level.

다시 말해서, 스위치(S/W)를 오프하기 전까지 가스를 한번감지하여 밸브(M)가 차단되면 계속해서 차단상태로 유지되는 것이다.In other words, the gas is sensed once until the switch S / W is turned off, and the valve M is shut off, so that it is kept in the shut-off state.

이후 다시 가스를 사용하고자 할때는 스위치(S/W)를 오프시켜 다시 초기상태가 되게 한 다음 스위치(S/W)을 온시키면 상기에서 설명한 바와 같은 과정을 거쳐 기기는 정상동작 되는 것이다.Then, when you want to use the gas again, turn off the switch (S / W) to the initial state and then turn on the switch (S / W) the device is operating normally through the process described above.

이상에서 설명한 바와같이 본 고안은 더모커플을 제거하고 가스센서를 사용한 IC회로를 사용하여 스위치 작동시 즉시 기기를 동작시킬 수 있고 가스를 감지하여 자동으로 밸브를 차단시키므로 기기에 대한 신뢰성을 높일 수 있으며 기기의 사용이 더욱 리해지는 효과가 있다.As described above, the present invention can remove the thermocouple and use the IC circuit using the gas sensor to operate the device immediately when the switch is operated, and detect the gas to automatically shut off the valve to increase the reliability of the device. The use of the device is more effective.
