자동 환기장치Automatic ventilation

본 고안의 회로도Circuit diagram of the present invention

본 고안은 동상의 정전압회로, 타임회로 및 감지호로에 I.C와 트랜지스터등의 결합으로 구성된 자동환기회로와 경보회로를 각각 분리 결접시켜서 가스가 발생하면 자동환기회로의 작동으로 환기가 되며 가스가 너무 많이 누설하여 환기를 미처못할 경우 즉, 위험한 수준의 량에 도달하면 자동경보되게 하여 별도의 방법으로 환기를 시킬 수 있게한 자동환기 장치에 관한 것이다.The present invention separates and connects the automatic ventilation circuit and alarm circuit composed of the combination of IC and transistor to the constant voltage circuit, the time circuit and the sensing circuit of the in-phase, respectively, and when the gas is generated, it is ventilated by the operation of the automatic ventilation circuit. The present invention relates to an automatic ventilation device that enables automatic alarming when leaking is not possible due to ventilation, that is, when a dangerous level is reached.

종래, 가스를 감지하여 경보를 발함과 동시에 환풍이 되게한 기구는 기히 개발된 것이 많이 있었으나 이는 그 구조가 환기회로와 경보회로가 같이 연결되어 있어서 소량의 가스등을 감지하여 환풍기가 동작중 일때도 일일이 밸이 울렸던 관계로 청각의 공해가 됐을뿐만 아니라 위험수준의 가스가 실내에 차있는지의 여부를 식별하기 어려웠던 결점이 있었다.Conventionally, there have been many mechanisms for detecting gas and generating an alarm at the same time. However, the structure is connected to a ventilation circuit and an alarm circuit, so that a small amount of gas is detected and the ventilator is in operation. Not only was the bell ringing, it was a hearing pollution, and it was difficult to identify whether a dangerous level of gas was in the room.

본 고안은 전술한 바와 같은 종래의 제반 결점을 제거키 위하여 안출한 것으로서 고안의 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to remove all the above-mentioned drawbacks as described above. The subject matter of the present invention will be described in detail with reference to the accompanying drawings.

트랜지스터(Q3)의 베이스에 저항(R1)(R2)과 가변저항(VR1) 반고정 저항(VR2) 및 콘덴서(C1)가 연결되고 콜렉터에 슈미트 I.C(IC1)가 연결되며 슈미트 I.C(IC1)의 출력단에 발광다이오드(LED1)(LED2)와 저항(R3)(R4)이 트랜지스터(Q4)의 베이스 사이에 연결되고 클렉터에 다이오드(D1)와 트랜스(T2)의 1차 코일이 연결되며 2차측 코일에는 콘덴서(C2)와 저항(R6)및 트라이악(T.C)이 연결하여서된 자동환기 회로(1)와 트랜지스터(Q5)의 베이스에 반고정저항(VR3)이 연결되고 콜렉터에 슈미트 I.C(IC2)가 연결되며 에미터에 더임스터(Th), 저항(R6)(R7)으로된 온도 보상회로(A)가 연결되고 슈미트 I.C(IC2)의 출력 단에 저항(R8) 트랜지스터(Q6) 및 부저(B)로 구성된 경보회로(2)에 통상의 정전압 회로(3)와 타임회로(4) 및 감지회로(5)를 결접하여서 된 것이다.A resistor (R 1 ) (R 2 ), a variable resistor (VR 1 ), a semi-fixed resistor (VR 2 ) and a capacitor (C 1 ) are connected to the base of the transistor (Q 3 ), and a Schmitt IC (IC 1 ) is connected to the collector. At the output of the Schmitt IC (IC 1 ), a light emitting diode (LED 1 ) (LED 2 ) and a resistor (R 3 ) (R 4 ) are connected between the base of the transistor (Q 4 ) and the diode (D 1 ) at the selector. And a primary coil of a transformer (T 2 ) are connected to the secondary coil, and a condenser (C 2 ), a resistor (R 6 ), and a triac (TC) are connected to the automatic ventilation circuit (1) and the transistor (Q 5 ). Semi-fixed resistor (VR 3 ) is connected to the base of the circuit, Schmitt IC (IC 2 ) is connected to the collector, and the temperature compensating circuit (A) consisting of the de-emitter (Th) and the resistor (R 6 ) (R 7 ) to the emitter. Is connected to an output terminal of the Schmitt IC (IC 2 ), and a constant constant voltage circuit (3) and a time circuit (4) and an alarm circuit (2) comprising a resistor (R 8 ) transistor (Q 6 ) and a buzzer (B). It was made by connecting the sensing circuit 5.

도면중 미설명 부호 F는 퓨우즈, Q1, Q2,는 트랜지스터 T, G, S는 가스감지기, S.K는 환풍기 소캣이다. 이와같이된 본 고안은 A, C가 입력되면 정전압회로(3)에서 직류로 평활화되어 안정된 직류전압이 가스감지기(T.G.S)에 인가된다.In the drawings, reference numeral F denotes a fuse, Q 1 , Q 2 , transistors T, G, and S denote a gas detector, and SK denotes a ventilator socket. In the present invention as described above, when A and C are input, the DC voltage is smoothed in the constant voltage circuit 3 so that a stable DC voltage is applied to the gas detector TGS.

여기에서 타임회로(4)는 가스감지기(T.G.S)에 전압이 인가되면 2분 정도는 가스 발생이 없이도 가스감지기(T.G.S)의 내부 저항이 낮아져 전압이 높게 발생하여 오동작이 발하게 되므로 오동작 발생을 방지하기 위한 회로이다.In this case, when the voltage is applied to the gas detector TGS, the internal resistance of the gas detector TGS is lowered for about 2 minutes without generating gas, so that the voltage is generated high and malfunction occurs, thereby preventing malfunction. For the circuit.

가스감지기(T.G.S)에 가스가 감지되면 그 출력측에 전압이 발생되어 반고정저항(VR4)을 통하여 자동환기 민감치가 설정되고 반고정저항(VR2)에 의하여 자동환기 둔감치가 설정이 된다.When gas is detected by the gas detector TGS, a voltage is generated at the output side, and the automatic ventilation sensitivity value is set through the semi-fixed resistor VR 4 , and the automatic ventilation desensitization value is set by the semi-fixed resistor VR 2 .

이 설정된 전압이 가변저항(VR1)에서 임의로 조정된 ②측으로 흘러 저항(R2)을 통하여 트랜지스터(Q3)의 베이스에 인가되는데 이 전압이 여기에서 증폭이 된 뒤 슈미트 I.C(I.C1)에 입력되어 그 출력측에 스위칭 전압이 발생된다.This set voltage flows to ② side arbitrarily adjusted in the variable resistor VR 1 and is applied to the base of the transistor Q 3 through the resistor R 2 , which is amplified here and then to the Schmitt IC IC 1 . The switching voltage is generated at the input side thereof.

이 스위칭 전압이 저항(R4)의 통하여 발광다이오드(LED2)에 흘러 발광된 뒤 트랜지스터(Q4)의 베이스에 인가되면 콜렉터와 다이오드(D1)을 통하여 트랜스(T2)의 일차측코일을 거쳐 2차측에 통하게 된다.When the switching voltage flows through the resistor R 4 to the light emitting diode LED 2 and emits light and is applied to the base of the transistor Q 4 , the primary coil of the transformer T 2 through the collector and the diode D 1 . Through the secondary side.

이렇게 스위칭 전압이 트랜스(T2)의 이차측에 인가되면 게이팅 전압이 발생하여 콘덴서(C2)를 거쳐 트라이악(T.C)의 게이트에 흐르면 트라이악(T.C)이 통전되어 환풍기 소켓(S.K)에 전원이 인가되므로 환풍기가 동작되는 것이다. 이때 환풍기에서 미쳐 다 환풍을 못할 정도로 다량의 가스가 발생되어 위험한 수준이 되면 가스감지기(T.G.S) 2차측에 높은 전압이 발생하게 된다.When the switching voltage is applied to the secondary side of the transformer T 2 , a gating voltage is generated and flows through the capacitor C 2 to the gate of the triac TC, whereby the triac TC is energized to connect to the fan socket SK. Since power is applied, the fan is operated. At this time, a large amount of gas is generated so that the exhaust fan can not be ventilated to a dangerous level, the high voltage is generated on the secondary side of the gas detector (TGS).

이 발생된 전압이 반고정 저하(VR3)에 이미 설정된 경보점의 전압보다 크게 발생이 되면 이 전압이 트랜지스터(Q5)의 베이스에 흘러 증폭이 된 뒤 콜렉터를 통하여 슈미트 I.C(I.C2)입력측에 인가되어 출력측에 스위칭 전압이 발생된다.If this generated voltage is greater than the voltage at the alarm point already set in the semi-fixed drop VR 3 , this voltage flows through the base of the transistor Q 5 to be amplified and then through the collector to the Schmitt IC (IC 2 ) input side. Is applied to generate a switching voltage on the output side.

이 스위칭 전압이 저항(R8)을 거처서 트랜지스터(Q6)의 베이스에 흘러 에미터와 콜렉터가 도통이 되어 부저(B)에 전원이 흘러 경보를 발하게 되는 것이다.The switching voltage flows through the resistor R 8 to the base of the transistor Q 6 to conduct the emitter and the collector so that power is supplied to the buzzer B to generate an alarm.

여기에서 온도 보상회로(A)는 가스감지기(T.G.S)가 실내 온도의 변화가 있더라도 그 내부 온도를 항상 일정하게 유지할 수 있는 회로이며 발광아이오드(LED1)는 환풍기가 작동을 안할때 이를 표시해 주기 위해서 점등도는 것이고 발광다이오드(LED2)는 환풍기가 동작할 때 이를 표시해 주기 위해서 점등되는 것이다.Here, the temperature compensation circuit (A) is a circuit capable of maintaining a constant internal temperature even if the gas detector (TGS) changes in room temperature, and the light emitting diode (LED 1 ) is used to indicate when the fan is not operating. will also light up the light-emitting diode (LED 2) it will be lit to indicate this period when the fan is operating.

또 만약에 반고정 저항(VR4)이 접촉 불량등의 고장이 발생될때는 저항(R1)에 의하여 전압이 트랜지스터(Q3)의 베이스에 인가되어 전기한 동작으로 환풍기 소켓(S.K)에 전원이 인가되어 계속 동작되게 한 것이다.In addition, when a failure such as a poor contact resistance VR 4 occurs in contact failure, a voltage is applied to the base of the transistor Q 3 by the resistor R 1 to supply power to the ventilator socket SK in an electrical operation. Is applied to continue operation.

이와같은 본 고안은 경보회로(2)와 자동환기회로(1)가 별개로 동작하게 되있어 소량의 가스가 발생되면 자동환기회로(1)의 동작으로 환기가 되는 것이며 또 위험수준 농도의 가스가 실내에 차 있으면 경보회로(2)의 동작으로 부저(B)가 경보를 발하게 되므로 별도의 방법으로 환기를 할 수 있어 거스로 부터의 위험을 예방할 수 있는 효과가 있는 것이다.The present invention is such that the alarm circuit (2) and the automatic ventilation circuit (1) is operated separately and when a small amount of gas is generated is ventilated by the operation of the automatic ventilation circuit (1) and the gas of dangerous level concentration If the car is indoors, the buzzer (B) will be alerted by the operation of the alarm circuit (2), so that the ventilation can be performed in a separate way, thereby preventing the danger from gauze.
