The water level sensing circuit unit 10 is formed by forming upper and lower portions, respectively, and connecting the AC / DC converters 14 and 14 'and the comparators 15 and 15', respectively.

미설명부호 16은 페라이트 코어이다.Reference numeral 16 is a ferrite core.

이와 같은 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as follows.

먼저 수산가스 발생기의 물탱크와 전해조의 수위가 최저 상태에서 전원을 온 시키면 물탱크 및 전해조의 수위 감지봉(13)에 형성된 인덕터(12)(12')중 하부 인덕터(12')에 수위에 따라 움직이는 페라이트 코어(16)가 위치하고 있으므로 발진부(11)에 의해 인덕터(12')의 저항이 커지면서 전류가 상대적으로 낮아진다. 이 낮아진 전류는 AC/DC 변환기(14')에 의해 DC로 변환되어 비교기(15')의 음(-)의 입력단에 로우신호가 입력된다. 비교기(15')의 음(-)의 입력단에 로우신호가 입력되면 비교기(15')는 하이신호를 출력한다.First, when the power level of the water tank and the electrolytic cell of the gas generator is turned on at the lowest state, the water level of the lower inductor 12 'of the inductors 12 and 12' formed in the water tank and the level sensor rod 13 of the electrolytic cell is lowered. Since the ferrite core 16 moves along, the resistance of the inductor 12 ′ is increased by the oscillator 11 so that the current is relatively low. The lowered current is converted into DC by the AC / DC converter 14 'so that a low signal is input to the negative input terminal of the comparator 15'. When a low signal is input to the negative input terminal of the comparator 15 ', the comparator 15' outputs a high signal.

수위감지회로부(10)의 비교기(15')의 하이신호의 출력으로 래치회로부(20)에서 급수밸브 릴레이스위치부(30)를 작동시켜 급수밸브를 온 시키는 것이다. 이때 급수시간 타이머부(40)가 래치회로부(20)의 신호를 받아 급수시간을 체크를 위하여 작동을 시작하고 대기시간 타이머부(50)는 작동을 멈춘다.By operating the water supply valve relay switch unit 30 in the latch circuit unit 20 with the output of the high signal of the comparator 15 ′ of the water level sensing circuit unit 10, the water supply valve is turned on. At this time, the water supply time timer unit 40 receives the signal from the latch circuit unit 20 to start the operation to check the water supply time and the standby time timer unit 50 stops the operation.

이와 같이 급수밸브가 열리고 물탱크와 전해조에 물과 전해액이 채워지면 수위 감지봉(13)의 페라이트 코어(16) 수위에 따라 상승하게 되고, 계속 상승하다 페라이트 코어(16)가 상부 인덕터(12) 위치까지 상승하면 인덕터(12)는 발진부(11) 및 페라이트코어(16)에 의해 저항이 커지면서 전류가 상대적으로 낮아진다. 이 낮아진 전류는 AC/DC 변환기(14)에 의해 DC 로 변환되어 비교기(15)의 음(-)의 입력단에 로우신호가 입력된다. 비교기(15)의 음(-)의 입력단에 로우 신호가 입력되면 비교기(15)는 하이신호를 출력한다.As such, when the water supply valve is opened and the water tank and the electrolytic solution are filled with water and the electrolyte, the ferrite core 16 rises according to the level of the ferrite core 16 of the water level sensing rod 13, and the ferrite core 16 continues to rise. When it rises to the position, the inductor 12 has a relatively high resistance due to the large resistance of the oscillator 11 and the ferrite core 16. The lowered current is converted into DC by the AC / DC converter 14 so that a low signal is input to the negative input terminal of the comparator 15. When a low signal is input to the negative input terminal of the comparator 15, the comparator 15 outputs a high signal.

수위감지회로부(10)의 비교기(15)로부터 하이 신호를 입력받은 래치회로부 (20)는 급수밸브 릴레이스위치부(30)를 작동시켜 급수밸브를 으프 시키는 것이다. 이와 동시에 급수시간 타이머부(40)는 래치회로부(20)의 신호로 급수시간 체크를 멈추고, 대기시간 타이머부(50)는 래치회로부(20)의 신호로 대기시간을 체크하기 시작한다.The latch circuit 20 receives the high signal from the comparator 15 of the water level sensing circuit 10 to operate the feed valve relay switch 30 to chuck the feed valve. At the same time, the water supply time timer unit 40 stops checking the water supply time with the signal of the latch circuit unit 20, and the waiting time timer unit 50 starts checking the waiting time with the signal of the latch circuit unit 20.

급수밸브가 오프되어 물탱크나 전해조에 물과 전해액 공급이 중단되면 수산가스 발생기의 작동으로 물탱크와 전해조의 물과 전해액이 소모되고 그에 따라 수위 감지봉(13)의 페라이트 코어(16)역시 하강하게 되는 것이다.When the water supply valve is turned off and the supply of water and electrolyte to the water tank or the electrolytic cell is stopped, the water gas and the electrolytic solution of the water tank and the electrolytic cell are consumed by the operation of the hydroxyl gas generator. Will be done.

페라이트 코어(16)가 하강하다 하부 인덕터(12')에 위치하게 되면 상기에서 설명한 바와 같이 급수밸브를 온 시켜 물과 전해액을 다시 공급하는 것이다.When the ferrite core 16 is lowered and positioned in the lower inductor 12 ', the water supply valve is turned on to supply water and the electrolyte again as described above.

여기서 물탱크와 전해조에 물과 전해액을 공급받고 있는 중에 급수시간 타이머부(40)는 급수시간을 체크하다, 이미 지정해 놓은 규정시간을 초과하여 급수가 될 때는 릴레이스위치부(70)로 신호를 보내어 가스밸브 및 전원 스위치를 오프시켜 수산가스 발생기의 작동을 멈추게 한다.Here, the water supply time timer unit 40 checks the water supply time while water and electrolyte are being supplied to the water tank and the electrolytic cell. When the water supply exceeds the specified time, the relay switch unit 70 sends a signal. Turn off the gas valve and power switch to stop the operation of the OH gas generator.

또한 물탱크와 전해조에 물과 전해액이 공급되지 않고 대기 중에 있을 때도 대기시간 타이머부(50)가 대기시간을 체크하여 이미 지정해 놓은 규정시간을 초과할 때는 릴레이스위치부(70)로 신호를 보내어 가스밸브 및 전원 스위치를 오프시켜 수산가스 발생기의 작동을 멈추게 한다.In addition, even when water and electrolyte are not supplied to the water tank and the electrolyzer, the standby time timer unit 50 checks the standby time and sends a signal to the relay switch unit 70 when the specified time exceeds the predetermined time. Shut off the valve and power switch to stop the operation of the OH gas generator.

한편 전해조의 외부 표면에 부착되어있는 바이메탈에 의해 온도를 감지하여 전해조 표면 온도가 60℃이상이 되거나, 전해조 또는 가스배관 등에서 수소가스가 누출되어 수산가스 발생기 내부의 수소가스 감지기에 1％이상의 수소가스 감지되거나, 전해조 내의 압력센서를 통하여 전해조 내의 압력이 3.5㎏이상일때는 안전회로부(60)가 작동되어 릴레리스위치부(70)로 신호를 보내어 가스밸브와 전원스위치를 오프시켜 안전사고를 미연에 방지하는 것이다.On the other hand, by sensing the temperature by the bimetal attached to the outer surface of the electrolyzer, the surface temperature of the electrolyzer becomes over 60 ℃, or the hydrogen gas leaks from the electrolyzer or the gas pipe, etc. When detected, or when the pressure in the electrolytic cell is greater than 3.5 kg through the pressure sensor in the electrolytic cell, the safety circuit unit 60 is activated and sends a signal to the relay switch unit 70 to turn off the gas valve and the power switch to prevent safety accidents. It is.
