본 고안은 가스 온수보일러의 순환펌프지연구동회로에 관한 것으로, 특히 주열교환기내에 온수코일이 구비되어 있는 2중 주열교환기를 이용한 가스온수보일러에 있어서, 온수사용후 정지시, 순환펌프를 구동시켜 버너에 의하여 가열된 2중 주열교환기내에 정체된 난방수를 순환시켜 줌으로써, 정체된 가열 난방수의 온도를 낮추어 난방수의 잠열로 인한 주열교환기의 과열 또는 핀이 용융되는 것을 방지하도록 한 가스온수보일러의 순환펌프지연구동회로에 관한 것이다.The present invention relates to a circulation pump paper research circuit of a gas hot water boiler, and in particular, in a gas hot water boiler using a double main heat exchanger having a hot water coil in the main heat exchanger, the circulation pump is driven when the hot water is stopped after use. By circulating the stagnant heating water in the double main heat exchanger heated by the burner, the gas hot water lowers the temperature of the stagnant heating heating water to prevent overheating of the main heat exchanger or melting of the fin due to latent heat of the heating water. It relates to the circulation pump paper research copper circuit of a boiler.

일반적으로 가스온수보일러는 주열교환기와 온수열교환기가 분리되어 있는 것과 주열교환기내에 온수코일이 구비된 2중 주열교환기로 된 것이 있는바, 전자의 경우 난방시 온수회로가 차단되고, 난방회로로 접속되면서 순환펌프를 구동시켜 버너로 가열된 주열교환기의 난방수를 순환시켜 주면서 난방을 하게되고, 난방중 온수사용시나 온수전용사용시에는 난방회로는 차단되고 온수회로로 접속되면서 순환펌프를 구동시켜 주열교환기에서 가열된 난방수로 온수열교환기를 가열시키고 가열된 온수열교환기는 내부의 온수코일로 급수되는 직수를 가열온수를 공급해 주게되고, 온수열교환기를 가열하던 난방수를 다시 주열교환기로 환수되어 재가열하면서 온수열교환기를 재가열시키는 순환경로로 하여 주열교환기의 난방수가 정체되지 않게 함으로써 난방수의 온도에 의하여 주열교환기의 과열이나 핀이 용융되는 문제점을 배제할 수 있으나, 후자의 경우에는 가스온수보일러의 순환펌프구동회로가 제1도에 도시한 바와 같이, 전원이력단(AC)에 릴레이 접점단자(RY1-P)를 통해 순환펌프(Pump)가 접속됨과 아울러 회로부에 정전압을 공급하는 트랜스(TRANS), 브리지정류기(BD) 평활용콘덴서(C1-C4) 정전압회로(Reg) 스위치(SW1)로 구성된 정전압부(가)와, 난방신호가 입력되는 저항(R1) 다이오드(D1)(D2)와 상기 순환펌프(Pump)의 구동을 제어하는 기준전압설정 저항(R2-R4)써모스타트(Th1)비교기(Comp1)와 저항(R5-R7), 트랜지스터(TR1)다이오드(D3) 릴레이(RY1)로 구성되는 순환펌프구동부(나)로 구성되어 있어 난방시에는 온수회로가 차단되고 난방회로로 접속되면서 난방신호에 의하여 순환펌프구동부(나)의 트랜지스터(TR1)를 온시키게되므로 순환펌프(Pump)를 구동하게되고 버너에 의하여 가열된 2중 주열교환기의 난방수를 순환시켜 주게되지만, 온수전용사용시 난방회로는 차단되고, 온수회로로 접속되게되므로 난방신호가 차단되게되어 상기 순환펌프구동부(나)를 구동을 하지 않게되고, 반면에 버너에 의하여 가열된 2중 주열교환기의 난방수는 정체된 상태로 가열되어 온수코일을 가열시켜 이 온수코일로 급수되는 직수를 난방수가 간접가열하므로써 온수를 공급하도록 되어 있다.In general, a gas hot water boiler is composed of a main heat exchanger and a hot water heat exchanger separated from each other and a double main heat exchanger equipped with a hot water coil in the main heat exchanger. By circulating the heating water of the main heat exchanger heated by the burner by driving the circulation pump while heating, the heating circuit is blocked when using hot water or exclusively for hot water during heating, and the circulating pump is connected to the hot water circuit to drive the main heat exchanger. The heated hot water heat exchanger is heated with heated water at The circulation path for reheating the equipment prevents stagnation of the heating water in the main heat exchanger. However, the problem of overheating of the main heat exchanger or melting of the fin due to the temperature of the heating water can be eliminated. However, in the latter case, the circulating pump driving circuit of the gas hot water boiler is shown in FIG. ) Circulating pump is connected through relay contact terminal RY1-P and transformer and bridge rectifier (BD) smoothing capacitor (C1-C4) constant voltage circuit that supplies constant voltage to circuit part. A constant voltage unit (A) composed of a switch SW1, a resistor R1 to which a heating signal is input, a diode D1 and a reference voltage setting resistor R2-R4 for controlling driving of the circulating pump. It consists of a circulating pump driving part (B) composed of a thermostat (Th1) comparator (Comp1), a resistor (R5-R7), a transistor (TR1), a diode (D3) and a relay (RY1). Transistor TR1 of circulating pump drive part (B) by heating signal while being connected to heating circuit Since it turns on, it drives the circulation pump and circulates the heating water of the double main heat exchanger heated by the burner, but when the hot water is exclusively used, the heating circuit is blocked and connected to the hot water circuit, which blocks the heating signal. Since the circulating pump drive unit (B) is not driven, the heating water of the dual main heat exchanger heated by the burner is heated in a stagnant state to heat the hot water coil to supply water directly to the hot water coil. Heating water supplies hot water by indirect heating.

그러나 장시간 온수사용후 중지하였을 때나 소량의 온수를 사용하고 중지하였을때 버너에 의하여 가열된 2중 주열교환기의 정체된 일정량 난방수는 온수코일과의 열교환이 이루어지지 않는 상태가 되고 바이메틸식 써모스타트로 일정온도 이상에서만 순환펌프를 구동시키도록 되어 있어 상기 정체된 난방수는 주열교환기의 휜을 가열 시켜주게 되어 잠열에 의한 온도의 급상승으로 심지어는 주열교환기의 휜을 용융시켜 2중주열교환기를 손상시키는 문제점을 가지게 되었다.However, when the water is stopped after using the water for a long time or when a small amount of water is used and stopped, the stagnant constant amount of heating water of the double main heat exchanger heated by the burner is in a state in which heat exchange with the hot water coil is not performed and the methyl thermostat The stagnant heating water heats the heat exchanger of the main heat exchanger so that the temperature rises due to the latent heat and even melts the heat exchanger of the main heat exchanger, thereby damaging the double main heat exchanger. I have a problem.

본 고안의 목적은 온수사용후 중지시 2중주열교환기내에 정체된 난방수가 잠열로 인해 온도가 급상승하거나 비등되는 것을 방지시켜 2중 주열교환기의 손상을 방지하는데 있으며, 상기의 목적을 실현하기 위하여 본 고안은 난방시 및 온수사용시 일정온도 이상에서만 구동하는 순환펌프 구동회로에 온수사용후 중지시 2중주열교환기내에 정체된 난방수를 순환시킬수 있도록 순환펌프를 소정시간 지연구동시킬 수 있는 순환펌프 지연구동부를 구성시킨 것을 특징으로 한다.The purpose of the present invention is to prevent the damage of the double main heat exchanger by preventing the temperature rise or boiling due to latent heat when the water stagnated in the double main heat exchanger stops after using the hot water. The circulating pump delay driving unit is capable of delaying the circulating pump for a predetermined time so as to circulate the stagnant heating water in the double main heat exchanger when it stops after using hot water in the circulating pump driving circuit which operates only at a certain temperature when heating and using hot water. It characterized in that the configuration.

이하 첨부된 도면에 의거 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 고안 가스온수보일러의 온수 및 난방온수겸용 사용시 순환펌프 지연구동부의 타이밍도를 나타낸 것으로 온수전용시에는 순환펌프 구동부가 온수 사용후 중지시에 nsec 동안 지연구동하고, 난방 온수겸용 사용시에는 온수동작후 무조건 nsec 동안 지연하되 난방 써모스타트의 온도가 일정온도 이하가 될때까지 계속 구동하게됨을 나타낸 것이다.Figure 3 shows the timing diagram of the circulating pump delay driving unit when using the hot water and heating hot water of the present invention gas hot water boiler. When the hot water is exclusively used, the circulating pump driving unit is delayed for nsec when the hot water is stopped after use. After the hot water operation unconditionally delayed for nsec, but continued to run until the temperature of the heating thermostat is below a certain temperature.

이하 본 고안의 작용효과를 설명하면 다음과 같다.Hereinafter will be described the effect of the present invention.

먼저 가스 온수보일러에 전원을 인가시키고 스위치(SW1)를 온시키면 전원입력(AC) 로부터 전원전압은 전원부(가)의 트랜스(TRANS)와 브리지정류기 (BD) 레귤레이터(Reg), 스위치(SW1)를 통해 정전압된 전압을 순환펌프구동부(나)에 공급하게된다.First, power is applied to the gas hot water boiler and the switch SW1 is turned on. Then, the power voltage from the power input AC is connected to the transformer (TRANS), bridge rectifier (BD) regulator (Reg), and switch (SW1). The constant voltage is supplied through the circulating pump driver (b).

이때 가스온수보일러가 난방을 하게 될때, 온수회로(도시되지 않음)는 차단되게 되고 난방회로가 접속되면서 난방회로의 출력신호가 순환펌프구동부(나)의 저항(R1) 다이오드(D1)를 통해 트랜지스터(TR1)의 베이스단자에 입력되게 된다.At this time, when the gas hot water boiler is heated, the hot water circuit (not shown) is cut off, and as the heating circuit is connected, the output signal of the heating circuit is transferred through the resistor (R1) diode (D1) of the circulation pump driving unit (B). It is input to the base terminal of TR1.

따라서 트랜지스터(TR1)는 온되므로 릴레이(RY1)가 동작하게되고 이 릴레이(RY1)의 동작에 의하여 전원입력단(AC)에 릴레이 접점(RY1-P)을 접속되어 순환펌프(Pump)에 전원을 인가시켜 주게 되므로 순환펌프(Pump)가 구동을 하게 된다.Accordingly, since the transistor TR1 is turned on, the relay RY1 is operated. The relay contact RY1-P is connected to the power input terminal AC by the operation of the relay RY1 to supply power to the circulating pump. Circulating pump (Pump) is driven.

이때 난방신호가 차단되더라도 난방중에 버너로인한 가열로 써모스타트(Th1)에서 감지된 온도에 대한 전압이 일정전압이상 일때 즉 기준전압설정 저항(R2-R4) 보다 높은 전압일때, 비교기(Comp1)의 비반전단자(+)에 입력되는 전압이 반전단자(-)에 입력되는 전압보다 크므로 비교기(Comp1)의 출력단에서는 하이신호가 출력되고 이 하이신호는 저항(R5)(R6)(R7)을 통해서 상기 트랜지스터(TR1)의 베이스단자에 계속해서 인가해주게 되어 상기 순환펌프(Pump)는 상기 써모스타트(Th1)에서 일정온도 이하로 떨어질 때까지는 계속 구동상태를 유지하게 된다.At this time, even if the heating signal is blocked, when the voltage of the temperature detected by the thermostat Th1 due to the burner during heating is higher than the predetermined voltage, that is, the voltage higher than the reference voltage setting resistors R2-R4, the comparator Comp1 Since the voltage input to the non-inverting terminal (+) is greater than the voltage input to the inverting terminal (-), a high signal is output from the output terminal of the comparator Comp1, and this high signal is applied to the resistors R5, R6, and R7. The circulating pump Pump is continuously applied to the base terminal of the transistor TR1 until the temperature falls below a predetermined temperature in the thermostat Th1.

한편 온수를 사용하기 위하여 온수를 틀게되면 난방회로는 차단되고 온수회로로 접속되면서, 유수검지용 마이크로스위치(2)의 접점은 a에서 a'로 접속되며 온수출력신호가 저항(R8)(R10)을 통해 순환펌프지연구동부(다)의 트랜지스터(TR2)의 베이스단자에 인가되어 트랜지스터(TR2)를 도통시키게되므로 트랜지스터(TR2)의 콜렉터단자는 저전위 상태로 되면서 비교기(Comp2)의 반전단자(-)로 입력되게 된다.On the other hand, when the hot water is turned on to use hot water, the heating circuit is cut off and connected to the hot water circuit, while the contact point of the water flow detection microswitch 2 is connected from a to a 'and the hot water output signal is a resistor (R8) (R10). It is applied to the base terminal of the transistor TR2 of the circulation pump paper research center (C) to conduct the transistor TR2 so that the collector terminal of the transistor TR2 is in a low potential state and the inverting terminal of the comparator Comp2 (-). Will be entered.

따라서 비교기(Comp2)의 비반전단자(+)에는 저항(R11)(R12)에 의하여 설정된 기준전압이 입력되게되고 이때 반전단자(-)로 입력되는 전압보다 비반전단자(+)로 입력되는 전압이 크므로 비교기(Comp2)의 출력단에서는 하이신호를 출력시키지만 이 하이신호는 다이오드(D5)(D2)를 통해 유수검지용 마이크로스위치(2)의 접점(a)를 통해 접지로 흘러나가게 되어 펌프구동을 멈추게 된다.Therefore, the reference voltage set by the resistors R11 and R12 is input to the non-inverting terminal + of the comparator Comp2, and at this time, the voltage inputted to the non-inverting terminal (+) rather than the voltage input to the inverting terminal (-). Since the output signal of the comparator Comp2 outputs a high signal, this high signal flows to the ground through the contacts D of the flow detection microswitch 2 through the diodes D5 and D2. Will stop.

이때 난방써모스타트(Th1)는 상기 2중 주열교환기가 열교환이 이루어지고 있으므로 일정전압이 이상되지 않아 비교기(Comp1)의 출력신호가 로우신호로 되어 순환펌프구동부를 구동시키지 못해 순환펌프(Pump)는 구동하지 않게 되는 것이다.At this time, since the dual main heat exchanger is heat-exchanged with the dual main heat exchanger, the output voltage of the comparator Comp1 becomes a low signal and the circulating pump driver cannot be driven because the dual main heat exchanger is heat-exchanged. It will not run.

한편 온수사용을 중지하게 되면 온수회로가 차단되고 마이크로스위치(2)의 접점이 a'에서 a로 절환되고 온수 출력신호가 없게되어 상기 순환펌프지연구동부(다)의 트랜지스터(TR2)의 베이스단자에 인가되는 신호가 없으므로 상기 트랜지스터(TR2)는 오프되게 되어 상기 트랜지스터(TR2)의 콜렉터단자에서는 고전위 상태전압이 나타나게 되고 이 고전위 전압은 저항(R10) 콘덴서(C5)에 의하여 충전되면서 비교기(Comp2)의 반전단자(-)에 입력되게 되고 이 입력되는 전압이 비교기(Comp2)의 비반전단자(+)에 입력되는 기준전압보다 상기 충전되는 전압이 높아질때까지 비교기(Comp2)의 출력전압은 하이신호가 출력되고 이때 유수검지용 마그네트스위치(2)의 개방되어 있어 상기 신호는 다이오드(D5)와, 순환펌프구동부(나)의 비교기(Comp1)의 출력단과 저항(R5)를 통해 트랜지스터(TR1)의 베이스단자에 인가시켜 트랜지스터(TR1)를 구동시키게 되므로 순환펌프(Pump)를 구동시키게 된다.On the other hand, if the hot water is stopped, the hot water circuit is cut off, the contact point of the micro switch 2 switches from a 'to a and there is no hot water output signal, so that the base terminal of the transistor TR 2 of the circulation pump paper research center (C) Since there is no signal applied to the transistor TR 2 , the transistor TR 2 is turned off so that a high potential state voltage appears at the collector terminal of the transistor TR 2 , and the high potential voltage is charged by the resistor R 10 capacitor C 5, and thus the comparator is charged. The output voltage of the comparator Comp2 is input to the inverting terminal (-) of (Comp2) until the charged voltage becomes higher than the reference voltage input to the non-inverting terminal (+) of the comparator (Comp2). The high signal is output and at this time, the water flow detection magnet switch 2 is opened, and the signal is transmitted through the diode D5, the output terminal of the comparator Comp1 of the circulation pump driving unit B, and the resistor R5. Since transistor thereby driving the transistor (TR1) was applied to the base terminal of (TR1), thereby driving the circulating pump (Pump).

이어서 일정시간 경과후 상기 콘덴서(C5)에서 충방전되는 전압이 상기 비반전단자(+)에 입력되는 전압보다 크게되며, 상기 비교기(Comp2)의 출력단자에는 로우신호가 출력되어 다이오드(D5)를 통해 비교기(Comp1)의 출력단으로 흘러가게되므로 순환펌프구동부(나)의 트랜지스터(TR1)을 구동시키지 못하게되어 순환펌프(Pump)를 정지 시켜주게 된다.Subsequently, after a predetermined time, the voltage charged and discharged by the capacitor C5 is greater than the voltage input to the non-inverting terminal +, and a low signal is output to the output terminal of the comparator Comp2 to supply the diode D5. Since it flows to the output terminal of the comparator Comp1, the transistor TR1 of the circulating pump driving part (b) cannot be driven to stop the circulating pump.

이때 온수전용 사용시에는 상기와 같이 온수사용 중지시 일정시간 순환펌프가 지연구동하다가 정지되게 되고, 난방중 온수사용하다가 온수사용을 중지하면 계속해서 난방신호에 의하여 순환펌프구동부(나)를 구동시켜 순환펌프(Pump)를 계속구동시켜 주게 되는 것이다.At this time, when using hot water only, the circulation pump stops after a certain period of time when the hot water is stopped, and when the hot water is stopped while using hot water during heating, the circulation pump driving part (B) continues to be driven by the heating signal. It keeps running the pump.

이상에서 설명한 바와 같이 본 고안은 난방중에 온수사용후 중지시나 온수전용사용후 중지시, 순환펌프를 구동시켜 2중주열교환기에 정체된 난방수를 순환시킴으로써 열교환을 시켜주게 되어 상기 난방수의 온도를 낮추게 되므로 난방수 비등으로 인한 주열교환기의 과열이나 휜의 용융을 방지시키게 되어 나아가서는 기기의 수명을 장구할 수 있는 이점을 제공하게 되는 것이다.As described above, the present invention stops the use of hot water during heating or stops after using only hot water, thereby circulating the stagnant heating water in a double main heat exchanger to lower the temperature of the heating water. Therefore, it is possible to prevent overheating of the main heat exchanger or melting of the fins due to boiling water heating, thereby providing an advantage of prolonging the life of the apparatus.
