* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 전원스위치 2 : 전원램프1: power switch 2: power lamp
3 : 발진회로 4 : 이상검지회로3: oscillation circuit 4: abnormal detection circuit
본 고안은 연소기에서 발생할 우려가 있는 실화(失火)등의 이상을 표시하는 이상표시장치에 관한 것이다.The present invention relates to an abnormality display device that displays an abnormality such as misfire caused by a combustor.
종래, 연소기에 있어서는 전원스위치를 닫았을 때 점등되는 전원램프와 별도로 이상이 발생하였을때 점등되거나 혹은 점멸되는 이상 표시램프를 설치하여 이상유무가 표시되게 하는 것을 일반적으로 채용하고 있으나, 부품수가 많고 배선작업도 번거롭게되는 문제점이 있다.Conventionally, in the combustor, it is generally adopted to install an abnormality display lamp that lights up or flashes when an abnormality occurs, in addition to the power lamp that is turned on when the power switch is closed. There is a problem that the work is cumbersome.
그러므로 본 고안은 전원램프를 이상표시램프로 겸용하고 부품수를 감소하여 상기한 종래의 문제점을 해소시킨 장치를 제공하는데 그 목적을 둔 것으로, 도면에 예시한 바와같이, 연소기의 전원스위치(1)를 닫았을 때 점등하는 전원램프(2)와, 그 램프(2)를 점멸하는 발진회로(3)를 구비하고 그 발진회로(3)를 연소기의 이상을 검지하는 이상 검지회로(4)에서의 검지신호로 발진작동되게한 것을 특징으로 한다.Therefore, the present invention aims to provide a device that combines a power supply lamp with an abnormal display lamp and reduces the number of parts to solve the above-mentioned conventional problems. As illustrated in the drawing, the power switch 1 of the combustor Power supply lamp 2 which lights up when the lamp is closed, and the oscillation circuit 3 which flashes the lamp 2, and the oscillation circuit 3 in the abnormality detection circuit 4 which detects abnormality of a combustor. It characterized in that the oscillation operation by the detection signal.
그 발진회로(3)는 전원램프(2)에 직렬로 된 출력측의 트랜지스터(5)를 가진 비교기(6)와, 그 비교기(6)의 「+」입력단자에 기준전압을 입력하는 분압회로(7)와 그 「-」입력단자에 충전전압을 입력하는 제 1 콘덴서(8)와 전원스위치(1)에 연결하는 그 제 1 콘덴서(8)의 충전회로(9)와, 비교기(6)의 출력측에 연결하는 그 제 1 콘덴서(8)의 방전회로(10)와, 그 제 1 콘덴서(8)의 충전을 제어하는 충전제어회로(11)로 구성하고 그 충전제어회로(11)와 연소기의 부하회로(12)와를 상기한 이상검지회로(4)의 검지신호로 트랜지스터(13)를 통하여 도통되는 릴레이(14)의 릴레이 스위치(15)를 개재하여 선택적으로 그 전원 스위치(1)에 접속하는 것으로 하였다.The oscillation circuit 3 comprises a comparator 6 having a transistor 5 on the output side in series with a power supply lamp 2, and a voltage divider circuit for inputting a reference voltage to the "+" input terminal of the comparator 6 ( 7) and the charging circuit 9 of the first capacitor 8 which connects the charging voltage to the "-" input terminal thereof and the first capacitor 8 connected to the power switch 1, and the comparator 6 The discharge circuit 10 of the first capacitor 8 connected to the output side, and the charge control circuit 11 for controlling the charging of the first capacitor 8, and the charge control circuit 11 and the combustor. Selectively connecting the load circuit 12 to the power switch 1 via the relay switch 15 of the relay 14 which is conducted through the transistor 13 with the detection signal of the abnormality detection circuit 4 described above. It was assumed that.
그 충전제어회로(11)는 제 1 콘덴서(8)측에서의 방전을 허용하는 다이오드(16)를 통하여 그 제 1 콘덴서(8)에 병렬로 접속한 방전용 저항(17)과 여기에 병렬로된 안정용 제 1 콘덴서(18)를 구비한다.The charge control circuit 11 has a discharge resistor 17 connected in parallel to the first capacitor 8 via a diode 16 allowing discharge at the first capacitor 8 side and a stabilizer parallel thereto. The first capacitor 18 is provided.
이어서 그 작도을 설명하면, 전원스위치(1)를 닫았을 때, 이상이 없으면 릴레이스위치(15)는 부하회로(12)측에 접속되어서, 이 부하회로(12)에의 통전이 행해지는 동시에, 충전회로(9)를 통하여 제 1 콘덴서(8)에의 충전이 행해지는데 이 경우 충전제어회로(11)의 저항(17)을 통해서의 방전으로 이 제 1 콘덴서(8)의 충전전압은 비교기(6)의 「+」입력단자에 입력되는 기준전압보다 낮게 유지되고, 이리하여 그 비교기(6)의 출력측에는 높은 레벨의 출력이 얻어져서, 트렌지스터(5)의 도통, 따라서 이것에 의한 전원 램프(2)의 점등이 이루어진다.Next, when the power switch 1 is closed, if there is no abnormality, the relay switch 15 is connected to the load circuit 12 side, and the energization of the load circuit 12 is performed and the charging circuit is performed. The charging of the first capacitor 8 is performed through (9), in which case the charge voltage of the first capacitor 8 is discharged through the resistor 17 of the charge control circuit 11. The voltage is kept lower than the reference voltage input to the "+" input terminal, whereby a high level output is obtained on the output side of the comparator 6, so that the conduction of the transistor 5 is conducted, and thus the power supply lamp 2 It is lit.
다음에 실화등의 이상이 생기면, 이상검지회로(4)에서의 검지출력에 의한 릴레이(14)의 통전으로 릴레이 스위치(15)가 충전제어회로(11)측으로 절환되고 부하회로(12)로 가는 통전이 차단되어, 발진회로(3)의 발진작동을 하게되는 것인데, 이것을 상술하면, 그 충전제어회로(11)의 릴레이 스위치(15)에서의 통전에 의하면 다이오드(16)의 충전 제어회로(11)측의 전압이 전원전압까지 상승하고, 제 1 콘덴서(8)로 부터의 방전이 정지되어서, 그 충전전압이 충전회로(9)를 통한 충전으로 상승되고, 이것이 기준전압을 넘으면 비교기(6)의 출력이 낮은 레벨이 되어 트렌지스터(5)가 도통하지 않게 되므로 전원램프(2)가 꺼지게 된다. 동시에 그 제 1 콘덴서(8)의 방전회로(10)에 의한 비교기(6)의 출력측으로의 방전이 이루어지고 그 충전전압이 저하되어 이것이 기준전압을 하회하면 그 비교기(6)의 출력이 다시 높은 레벨로 반전하고 트렌지스터(5)의 도통에 따라 전원램프(2)가 켜지게 된다. 동시에 그 방전회로(10)에 의한 방전이 정지되고, 그 제 1 콘덴서(8)의 충전전압이 다시 상승되면 그 반복으로 전원램프(2)가 점멸된다.Next, when an abnormality such as a misfire occurs, the relay switch 15 is switched to the charge control circuit 11 side by the energization of the relay 14 by the detection output from the abnormality detection circuit 4 and goes to the load circuit 12. The energization is cut off to cause the oscillation circuit 3 to oscillate, which is described above. According to the energization of the relay switch 15 of the charge control circuit 11, the charge control circuit 11 of the diode 16 is applied. The voltage on the side increases to the power supply voltage, the discharge from the first capacitor 8 is stopped, and the charging voltage is increased by the charging through the charging circuit 9, and when it exceeds the reference voltage, the comparator 6 The power supply lamp 2 is turned off because the output of the low level causes the transistor 5 not to conduct. At the same time, the discharge to the output side of the comparator 6 by the discharge circuit 10 of the first capacitor 8 is made, and the charge voltage is lowered. When this falls below the reference voltage, the output of the comparator 6 is again high. The power lamp 2 is turned on as the level is reversed and the conduction of the transistor 5 is conducted. At the same time, the discharge by the discharge circuit 10 is stopped, and when the charging voltage of the first capacitor 8 rises again, the power supply lamp 2 flashes repeatedly.
이와같이 본 고안에 의하면 이상 발생시에 발진회로(3)의 발진작동으로 전원램프(2)를 점멸하여 이상발생을 표시하는 것으로서, 별개의 이상표시램프를 사용할 필요가 없고, 부품수를 줄여서 배선작업을 간략하게 할 수 있는 효과가 있다.As described above, according to the present invention, when the abnormality occurs, the oscillation operation of the oscillation circuit 3 flashes the power lamp 2 to indicate the occurrence of an abnormality. There is an effect that can be simplified.
