본 고안은 가스렌지용 안진밸브의 초기일시 개방회로에 관한 것이다.The present invention relates to the initial temporary open circuit of the bleed valve for the gas stove.

가스렌지는 가스누출에 의한 사고위험이 뒤따르므로 안전 관리에 중점을 두고 설계된다.Gas stoves are designed with a focus on safety management because of the risk of accidents from gas leakage.

일예로서 가스렌지에는 가스자동차단용 안전밸브가 부착되어 있고. 이 안전밸브는 상시 폐쇄형의 것으로 비연소 상태에서 가스가 분츨되는 것을 방지해 주고있다.For example, a gas stove has a safety valve for gas shut off. This safety valve is normally closed and prevents gas from being discharged in the unburned state.

안전밸브의 기능을 상세히 설명하면 기스렌지의 정상 연소 상태여부를 감지하는 열진대 감지기에 의해 제어되이 개폐되는 것이며, 열전대 감지기는 가열되면 전압이 밭생되어 안진 밸브를 열어구고. 반대로 열전대 감지기가상온으로 닝각되면 전압이 소실되어 안전밸브는 폐쇄상태로 복귀되어 지는 것이다.In detail, the function of the safety valve is controlled by a thermocouple detector that detects the normal combustion state of the gas range. The thermocouple detector opens the seismic valve by heating the voltage when heated. On the contrary, when the thermocouple detector is inclined to room temperature, the voltage is lost and the safety valve is returned to the closed state.

상술한 안전밸브에 의해 비연소 상태에서 가스가 누출됨에 따르는 위험을 피할 수 있게 되있으나 최초 사용시 사용자는 점화후 옅전대 감지기가 가열될 때까지 수동노브를 조작하여 10-20초간 안전밸브를 강재로 열어 주어야하는 불편이 생기게 되었다.The above-mentioned safety valve prevents the risk of leakage of gas in non-combustion state.However, in the first use, the user can operate the manual knob until the sub-electric detector is heated after ignition, The inconvenience of opening up came.

이를 해결하려면 수동노브를 조작하여 점화가 되어짐과 동시에 열전대 감지기가 가띨될 매까지 안전밸브를 개방시켜 주는 장치가 필요하게 된다.To solve this problem, a device is needed to operate the manual knob to ignite and to open the safety valve until the thermocouple detector is closed.

본 고안의 목적인 상술한 결점을 해결하기 위하여 안출된 것으로 점화와 동시에 작동하여 열전대 감지기가 가열될 때까지 안전밸브를 동작시켜 주고, 그 후에는 스스로 전원이 차단되어지는 가스렌지용 안전밸브의 초기일시 개방회로를 제공함에 있다.In order to solve the above-mentioned shortcomings of the present invention, the safety valve is operated until the thermocouple detector is heated by operating at the same time as the ignition, after which the initial time of the safety valve for the gas stove is cut off by itself. In providing an open circuit.

이하 본 고안을 첨부도면에 따라 상세히 설명한다,Hereinafter, the present invention will be described in detail according to the accompanying drawings.

본고안은 제1도의 도시와같이 점화감지부(1)과, 플립플롭(1)및 시간설정부(3)그리고 안전밸브구동부, (4)로 구성된다.This design consists of an ignition detection unit 1, a flip-flop 1 and a time setting unit 3, and a safety valve driving unit 4 as shown in FIG.

사용자가 가스렌지를 점화시키면 이와 동시에 점화감지부(1) 감지신호가 발생되고, 이 신호는 플립플롭[2)을 거쳐 시간설정부[3)에서 설정시간동안 존속되어 안전밸브 구동부(4)를 스윗치-온 시켜준다.When the user ignites the gas stove, an ignition detection unit (1) detection signal is generated at the same time, and the signal persists for a predetermined time in the time setting unit (3) via the flip-flop (2) to operate the safety valve driving unit (4). Switch on.

설정시간이 지나 플립플롭(2)가 리세트신호에 의해 리세트 되면 안전밸브 구동부(4)는 스위치-오프로 되어진다.When the flip-flop 2 is reset by the reset signal after the set time, the safety valve driving unit 4 is switched off.

상기한 본 고안에서 각 부본의 회로구성은 제2도의 도시와 같다.In the above invention, the circuit configuration of each book is shown in FIG.

점화감지부(1)은 코일 또는 금속튜우브와 같은 Re와 낸드게이트 N1으로 이루어지고 그 사이에 보호저항R1, R2 그리고 전압 안정용 제너다이오드 ZD가 개재된다.The ignition detection unit 1 is composed of Re, such as a coil or metal tube, and a NAND gate N1, and interposed therebetween protective resistors R1, R2 and a zener diode ZD for voltage stabilization.

플립플롭(2)는 통상적인 쌍안정 멀티 바이브레터로서 낸드게이트 N2, N3로 이루어진다.The flip-flop 2 is a conventional bistable multivibrator consisting of NAND gates N2 and N3.

시간설정부(3)온 설정시간에 상상당하는 시청수를 갖는 저항 R3. 콘댄서 C와 리세트신호 츨력용 소자로서의 낸드개이트 N4로 이루어지고 다이오드 D는 콘댄서 C의 방전용 다이오드이다.Resistor R3 having the number of views imagined at the time setting section 3 setting time. It consists of the condenser C and the NAND gate N4 as an element for the reset signal output, and the diode D is the discharge diode of the condenser C.

안전밸브 구동부(4)는 NPN트랜지스터 Q1과 PNP트랜지스터 Q2를 직결시키고, 플립플롭(2)로부터 보내지는 신호에 의해 NPN트랜지스터 Q1, PNP트랜지스터 Q2가 순차 도통하게 된다.The safety valve driving unit 4 directly connects the NPN transistor Q1 and the PNP transistor Q2, and the NPN transistor Q1 and the PNP transistor Q2 are sequentially conducted by a signal sent from the flip-flop 2.

저항 R4. R5는 바이어스용이다.Resistance R4. R5 is for bias.

도면의 미설명부호BT는 전원용 건전지. 부호5는통상적인 가스렌지이며, 부호6은 가스렌지이며 장치된 점화수단으로서의 압전기, 부호7은 압전기(6)의 조작노브, 부호8은 전자력에 의해 개방되는 가스렌지(5)의 안전밸브, 부호 EH는 안전밸브(8)을 개폐체이하는 열전대감지기이다.In the drawings, reference numeral BT denotes a battery for power. Reference numeral 5 denotes a conventional gas stove, reference numeral 6 denotes a gas stove and a piezoelectric element as an ignition means installed, reference numeral 7 denotes an operation knob of the piezoelectric member 6, reference numeral 8 denotes a safety valve of the gas stove 5 opened by electromagnetic force EH denotes a thermocouple sensor for opening and closing the safety valve 8.

상술한 본 고안은 정전유도체 Re를 압전기(6)의 도선에 장치하여 사용하는 겻으로서 사용자가 조작노브(7)을 쥐고 압전기(6)을 작동시킬 때 주지된 바와 같이 도선에는 고전류가 흘러 가스렌지(5)와의 대향지점에서 불꽃을일으키게 된다.The present invention described above uses the electrostatic inductor Re in the conductor of the piezoelectric element 6, and when the user grips the operation knob 7 to operate the piezoelectric element 6, as is well known, a high current flows through the conductor to the gas stove. At the point opposite to (5), a spark is generated.

이때 도선에 고전류가 흐르는 순간, 정전유도체 Re에는 정전유도전압이 유기된다.At this time, when a high current flows through the conductor, an electrostatic induction voltage is induced in the electrostatic conductor Re.

이 신호(+)신호는 낸드게이트N1에 인가되어 출력단에서는 (-)반전된 동작신호가 플립플롭(2)의 낸드게이트 N2에 가해진다.The signal (+) is applied to the NAND gate N1, and a negative (-) inverted operation signal is applied to the NAND gate N2 of the flip-flop 2 at the output terminal.

(-) 신호를 받은 낸드게이트 N2는 출력단으로 (+) 신호를 송출하여 안전밸브 구동부(4) 를 스욋치-온 시키게된다.The NAND gate N2 receiving the (-) signal sends a (+) signal to the output stage to turn on the safety valve driver 4.

한편. 낸드개이트 N2로부더의 (+)신호는 시간설정부(3)의 저항 R3와 콘댄서 C에 의해 설정된 시정수 만큼 예컨대 10-20초간 지속된다,Meanwhile. The (+) signal of the NAND gate N2 loader lasts, for example, for 10-20 seconds by the time constant set by the resistor R3 and the condenser C of the time setting section 3,

시정수에 의해 설정된 시간동안 충전되고 있던 콘덴서가 충전이 끝나면 낸드게이트 N4를 동작시켜 리세트신호를 플립플롭 (2)로 보내게 된다.When the capacitor, which has been charged for the time set by the time constant, finishes charging, the NAND gate N4 is operated to send the reset signal to the flip-flop (2).

리세트신호는 (-)신호로서 플립플롭(2)의 낸드게이트N3에 인가되어 그 츌릭단에서 (+)신호로 반전된 선호를 낸드게이트N2에 인가함에 따라 N2의 출력단에는 이제와는 달리(-)신호가 츨력되어, 안전밸브 구동부(4)를스윗치-오프시켜 구개 됨과 동시에 콘덴서 C의 충전 전압온 다이오드 D를 통해 방전된다.The reset signal is applied to the NAND gate N3 of the flip-flop 2 as a (-) signal and applied to the NAND gate N2 inverted by a positive signal at its logic stage. The signal is outputted, and the safety valve drive unit 4 is switched off and then discharged through the charging voltage-on diode D of the capacitor C.

안전밸브 구동부(4)는 플립플롭(2)에 의해 스윗치-온 되면 전전지(BT)의 에너지로 안전밸브(8)을 여자하여 개방시켜 준다.When the safety valve driving unit 4 is switched on by the flip-flop 2, the safety valve driving unit 4 excites and opens the safety valve 8 by the energy of the electric battery BT.

상기한 과정에 의해 사용자가 압전기(6)을 작동해 주기만 하면 본 고안의 회로가 이를 즉시 감지하여 안전밸브(8)을 실청시간 동안 개방시켜 주기 매문에 증래와 같이 열전대 감지기 EH가 가일되는 시간 동안 안전밸브를수동개방시져 필요성이 생략되어 보다 편리하게 가스렌지를 사용할 수 있게 된다.If the user only operates the piezo 6 according to the above process, the circuit of the present invention immediately detects this and opens the safety valve 8 for the actual time. Manual opening of the safety valve eliminates the need for a more convenient gas stove.

열전대 감지기 EH가 가열되어 안전밸브를 동작시켜 주기 때문에 설정시간 후 안전밸브 구동부(4)가 스윗치-오프 외에도 안전밸브(8)이 폐쇄되지 않으므로 사용에 지장을 주는 일은 없다.Since the thermocouple detector EH is heated to operate the safety valve, the safety valve driving part 4 does not close the safety valve 8 in addition to the switch-off after the set time.
