본 고안은 가스보일러의 배기팬 속도조절장치에 관한 것으로, 특히, 정상연소를 위한 공기량을 적절히 흡입하여, 공급되는 가스량의 비율과 항상 일정한 비율의 공기량이 흡입되도록한 가스보일러의 배기팬 속도조절장치에 관한것이다.The present invention relates to an exhaust fan speed control device for a gas boiler, and in particular, an exhaust fan speed control device for a gas boiler in which a proper amount of air for normal combustion is inhaled so that a proportion of the supplied gas amount and a constant amount of air are always inhaled. It's about.

일반적인 가스보일러의 운용시 가스공급관을 통해 유입되는 가스량은 항상 일정한 반면에 완전연소에 필요한 공기량은 주위의 환경, 자연상태, 기후에 따라 많은 차이가 있어 흡입되는 공기량이 일정치 못하여, 이로인해 불완전 연소에 따른 폐가스 방출 및 열효율을 저하시키는 등의 문제점이 발생되었다.While the amount of gas flowing through the gas supply pipe is always constant during operation of a general gas boiler, the amount of air required for complete combustion varies greatly depending on the surrounding environment, natural conditions, and climate, and thus the amount of intake air is not constant, resulting in incomplete combustion. Problems such as reducing the waste gas emissions and thermal efficiency caused by.

이에 본 고안은 상술한 바와같은 종래의 문제점을 해소키 위해 안출된 것으로, 버어너의 불꽃상태를 감지하여 불완전 또는 완전연소에 따른 배기팬의 회전속도를 조절하여 항상 일정한 양의 공기가 공급되도록한 가스보일러의 배기팬 속도조절장치를 제공하는데 그 목적이 있는 것이다.The present invention has been devised to solve the conventional problems as described above, by detecting the flame state of the burner to adjust the rotational speed of the exhaust fan according to incomplete or complete combustion so that a constant amount of air is always supplied. It is an object of the present invention to provide a gas boiler exhaust fan speed control device.

이하, 첨부된 도면을 참조하여 구성 및 작용효과를 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration and operation effects will be described in detail.

본 고안의 목적을 달성하기 위하여, 도면 제1도에서 보는 바와같이 연소버어너의 불꽃상태를 프레임로드(FR)를 통해 감지하고, 감지된 신호를 제어부(4)로 출력토록된 불꽃상태 감지부(1)와, 제어부(4)의 지시에 따라 팬모터의 회전속도를 가변토록된 조절부(2)와, 조절부(2)의 지시신호를 받고 모터를 구동하여 공기량의 공급을 조절토록된 모터구동부(3)와, 상기 각부와 연결되어, 모든동작을 지시통제토록된 제어부(4)를 구비하여 구성된 것으로, 미 설명부호 5는 점화수단인 것이다.In order to achieve the object of the present invention, as shown in FIG. 1, the flame state of the combustion burner is detected through the frame rod FR, and the flame state detection unit outputs the detected signal to the controller 4. (1) and the control unit (2) for varying the rotational speed of the fan motor according to the instructions of the control unit (4), and receiving a signal from the control unit (2) to drive the motor to regulate the supply of air volume. The motor drive part 3 and the control part 4 connected to each said part and which all the operation | movement was controlled by instruction | indication are comprised, The reference numeral 5 is an ignition means.

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

도면 제2도에서 보는 바와같은 동작흐름을 갖는 본 고안은, 초기에 전원을 인가하고. 난방모드 위치를 설정하게되면, 1차가스밸브가 열리면서 점화수단(Ignitor)에 고전압을 발생시켜 불꽃이 튀기기 시작한다.The present invention having an operation flow as shown in FIG. 2 initially applies power. When the heating mode is set, the primary gas valve is opened to generate a high voltage to the ignition means and the sparks start to splash.

이와동시에, 펌프와 모터구동부(3)의 팬이 돌게되고, 프레임로드(FR)를 통해 연소버어너의 불꽃상태를 감지하게되는데, 불꽃이 정상일 경우 정상연소가 되지만, 미리설정된 기준상태보다 불꽃상태가 이상으로 감지되면, 즉, 프레임로드를 통해 제어부로 들어오는 신호가 일정이상일 경우에, 제어부(1)에서는 유입되는 가스량보다, 완전연소에 필요한 공기량이 적은것으로 판단하여, 조절부(2)를 통해 모터구동부(3)의 팬모터 회전속도를 높여, 많은양의 공기가 유입되도록 한다.At the same time, the fan of the pump and the motor driving unit 3 is turned, and the flame state of the combustion burner is detected through the frame rod FR. If the flame is normal, the combustion is normal, but the flame state is higher than the preset reference state. If is detected as abnormal, that is, when the signal coming into the control unit through the frame rod is a predetermined or more, the control unit 1 determines that the amount of air required for complete combustion is less than the amount of gas flowing through, through the control unit (2) Increasing the fan motor rotation speed of the motor driving unit 3, so that a large amount of air is introduced.

또한, 버어너의 볼꽃상태가 설정된 상태보다 이하로 떨어지면 유입되는 가스량보다 공기의 양이 많다고 판단하여 조절부(2)를 통해 모터구동부(3)의 팬모터 회전수를 낮추어 항상 완전연소에 필요한 양의 공기가 유입되도록 하는 것이다.In addition, when the ball flower state of the burner falls below the set state, it is determined that the amount of air is larger than the amount of gas introduced, and thus the fan motor rotation speed of the motor driving unit 3 is lowered through the adjusting unit 2 so that the amount required for complete combustion is always maintained. To let the air in.

한편, 도면 제3도에서 보는 바와같이 불꽃상태감지부(1)의 동작은 초기전원을 온하면, 콘덴서(C1)을 거치면서 AC전원이 제거되고, 저항(R8)을 통해 전류 제한되어, 콘덴서(C2)와 재너다이오드(ZD1)측으로 흐르면, 직류전압으로 변환되면서, 전계효과 트랜지스터(FET)이 게이트(G) 단자에 인가되어 전계효과 트랜지스터(FET)는 턴온된다.On the other hand, as shown in Figure 3, the operation of the flame state detection unit 1, when the initial power is turned on, the AC power is removed through the capacitor (C1), the current is limited through the resistor (R8), the capacitor When flowing to the side of C2 and the zener diode ZD1, the field effect transistor FET is applied to the gate G terminal while being converted into a DC voltage, and the field effect transistor FET is turned on.

이때. 저항(R4)에 흐르는 전압이 콘덴서(C3)에 충전이 되지않으므로, 오피앰프(OP) "-"극에 저출력값의 전압이 인가되어 저항(R5, R6)에 인가되는 전압보다 낮으므로 오피앰프(OP)의 출력단으로 저출력값의 신호가 나와 저항(R7)을 통해 트랜지스터(Q1)가 턴오프 되므로, 그와 조합된 점화에 필요한 작동수단이 동작하면서 착화가 된다.At this time. Since the voltage flowing through the resistor R4 is not charged to the capacitor C3, the voltage of the low output value is applied to the op amp OP "-" pole and is lower than the voltage applied to the resistors R5 and R6. Since the signal of low output value is output to the output terminal of OP and transistor Q1 is turned off through resistor R7, the operation means necessary for the ignition combined therewith operates and is ignited.

또한, 저항 (R4)과 콘덴서(C3)가 충전시간을 가지므로 이시간동안 불꽃감지를 못하면 오피앰프(OP)가 반전이되어 출력단으로 고출력값을 내므로 트랜지스터(Q1)는 턴온되면서 점화수단(5)의 불이 소화되는 것이다.In addition, since the resistor (R4) and the capacitor (C3) has a charging time, if the flame is not detected during this time, the op amp (OP) is inverted to give a high output value to the output terminal, so that the transistor Q1 is turned on and the ignition means ( 5) the fire is extinguished.

여기에서, 프레임로드의 불꽃감지는, 프레임로드(FR)가 루프(loop)형성되어 전계효과트랜지스터(FET)에 걸린 게이트(G)전압이 프레임로드(FR)쪽으로 흘러, 전계효과 트랜지스터(FET)가 턴오프되면, 콘덴서(C2)에 걸린 충전전압이 오피앰프(OP) "+"극에 계속 하이신호가 되어 점화수단은 동작되지 않게된다.The flame detection of the frame load includes a frame load FR formed in a loop, and a gate G voltage applied to the field effect transistor FET flows toward the frame load FR. When is turned off, the charging voltage applied to the capacitor C2 continues to be a high signal to the op amp OP "+" pole so that the ignition means is not operated.

이상에서 본 바와같이 버어너의 연소불꽃의 상태가 설정된 상태보다 이상과, 이하가 됨을 감지하고 완전연소에 필요한 공기의 공급량을 팬모터의 회전속도로 조절되도록 하므로 종래에 따르던 제반문제점을 배저토록한 고안인 것이다.As seen above, the burner's combustion flame condition is above and below the set state, and the amount of air required for complete combustion is controlled by the rotational speed of the fan motor. It is an idea.
