본 고안은 가스보일러의 온수온도제어에 관한 것으로, 특히 온수를 사용한 다음 잠시후 다시 온수를 사용할 때 발생되는 현상(찬물이 일정시간 나온다)을 일소하도록 하여 항상 온수만을 사용할 수 있도록 한 가스보일러의 온수온도제어회로에 관한 것이다.The present invention relates to the hot water temperature control of a gas boiler, and in particular, to remove the phenomenon (cold water comes out for a certain time) occurring when using hot water again after using hot water for a while, so that only hot water is always used. It relates to a temperature control circuit.
종래의 가스보일러의 경우, 온수를 사용하고 난 뒤 잠시후 다시 온수를 사용하게 되면 찬물이 나오는 현상이 발생하였다. 이는 온수의 사용을 중단하는 것과 동시에 보일러가 난방회로로 복귀됨에 따라 열교환기에 머물러 있던 온수가 상대적으로 온도가 낮은 난방수로 역 열교환이 이루어지게 되는 관계로 찬물이 나오는 것이었다.In the case of the conventional gas boiler, when the hot water is used again after using hot water for a while, cold water is generated. The cold water came out because the hot water stayed in the heat exchanger was reversely heat-exchanged with the heating water having a relatively low temperature as the boiler was returned to the heating circuit at the same time as the use of the hot water was stopped.
이유는 온수사용중단 직후의 온수의 온도가 난방수의 온도보다 높기 때문에 발생하는 것으로 사용자들은 온수사용시 큰 불편함을 느끼게 되었다.The reason is that the hot water immediately after the hot water is stopped is higher than the heating water temperature, and users feel great inconvenience when using hot water.
따라서, 본 고안의 목적은 상기 문제점을 해결하고자 안출된 것으로, 전술한 바와같이 온수사용이 중단된 시점부터 일정시간 버너의 화력을 최대로 하여 난방수의 온도를 상승시켜주어 온수가 난방수와 열교환되는 현상을 방지함으로써 재 온수사용시 찬물이 나오는 현상을 방지할 수 있도록 한 가스보일러의 온수온도 제어회로를 제공하는데 있다.Accordingly, an object of the present invention is to solve the above problems, as described above, by maximizing the thermal power of the burner for a certain time from the point where the use of hot water is stopped to increase the temperature of the heating water, the hot water is heat exchanged with the heating water. It is to provide a hot water temperature control circuit of a gas boiler that can prevent the phenomenon of cold water when using the hot water to prevent the phenomenon.
이하, 첨부된 도면에 의거하여 본 고안을 설명한다.Hereinafter, the present invention will be described based on the accompanying drawings.
제1도는 보일러의 일반적인 계통도 및 본 고안에 따른 제어 블럭도를 도시한 것으로, 버너(10)의 화력으로 열교환기(1)는 가열되고 내부 난방수가 온도상승하여 난방공급관(2), 삼방변(3) 및 배관(4)을 통하여 난방작용을 한뒤 난방 환수관(5)을 통해 다시 열교환기(1)로 환수되어 소모된 열을 다시 보충받는다. 또한, 급수관(6)을 통해 열교환기(1) 내부의 온수관(7)으로 투입된 찬물은 열교환기(1) 내부의 난방수와 열교환되고 온도상승되어 온수공급관(8)을 통해 사용자의 용도에 따라 쓰여진다.1 is a general schematic diagram of a boiler and a control block diagram according to the present invention. The heat exchanger 1 is heated by the thermal power of the burner 10, and the internal heating water temperature rises. 3) and after the heating operation through the pipe (4) is returned to the heat exchanger (1) again through the heating return pipe (5) to replenish the heat consumed again. In addition, the cold water introduced into the hot water pipe (7) inside the heat exchanger (1) through the water supply pipe (6) is heat exchanged with the heating water inside the heat exchanger (1) and the temperature is increased to the user's use through the hot water supply pipe (8) Is written accordingly.
한편, 본 고안에 따른 프로그램을 내장한 단일 칩 마이크로 컴퓨터인 제어부(13)는 온수사용시 급수관(6)에 설치되어 있는 플로우 밸브(9)의 일정신호를 입력받아 삼방변(3)에 일정신호를 출력하여 난방수가 배관(4)으로 흐르는 것을 차단하여 결국은 난방수가 난방공급관(2), 삼방변(3) 및 난방환수관(5)을 통하여 다시 열교환기(1)로 순환되는 폐회로를 구성하여 주어 온수관(7)에 열교환이 용이하도록 하여주며 본 고안에 따른 프로그램에 의해 온수사용이 막 중단된 시점을 플로우 밸브(9)로 부터 인식하여 가스공급관(11)에 설치된 가스밸브(12)로 일정신호를 일정시간 출력하되, 버너(10)의 화력이 최대로 되게 하여준다.On the other hand, the control unit 13, which is a single-chip microcomputer with a program according to the present invention, receives a constant signal from the flow valve 9 installed in the water supply pipe 6 when hot water is used, and transmits a constant signal to the three-sided sides 3. Outputs and blocks the heating water from flowing into the pipe (4) and eventually forms a closed circuit in which the heating water is circulated back to the heat exchanger (1) through the heating supply pipe (2), the three-way (3) and the heating return pipe (5) To facilitate heat exchange in the hot water pipe (7) and to recognize the time when the hot water is just stopped by the program according to the present invention from the flow valve (9) to the gas valve (12) installed in the gas supply pipe (11) While outputting a predetermined signal for a certain time, the fire power of the burner 10 is maximized.
제2도는 본 고안에 따른 회로도를 도시한 것으로, 제어부(13)의 입력포트(P1)에는 플로우밸브(9), 저항(17) (18)으로 구성된 온수사용 감지부(14)가 접속되어 급수관(6)의 물의 흐름에 따라 온, 오프되는 플로우 밸브(9)의 신호로 제어부(13)의 입력포트(P1)에는 로우 또는 하이신호가 입력되는 것이다.2 is a circuit diagram according to the present invention, the input port (P 1 ) of the control unit 13 is connected to the hot water use detection unit 14 consisting of a flow valve (9), a resistor (17) (18) The low or high signal is input to the input port P 1 of the control unit 13 as a signal of the flow valve 9 which is turned on and off in accordance with the flow of water in the water supply pipe 6.
따라서 제어부(13)는 입력포트(P1)로의 로우 또는 하이신호에 따라 온수 사용여부를 판단하게 된다. 다시말해서 온수를 사용하면 급수관(6)으로 물이 흐르게 되고 플로우 밸브(9)는 이를 감지하여 온 상태로 전환된다. 따라서 제어부(13)의 입력포트(P1)에는 로우신호가 입력되는 것이다. 또한, 제어부(13)의 출력포트(P2)에는 인버터(19), 다이오드(20), 릴레이(21) 및 가스밸브(12)로 이루어진 가스밸브 구동부(15)가 접속되어 출력포트(P2)로의 하이 출력시 릴레이(21)가 온되어 가스밸브(12)가 구동(개방)하게 되는 것이다.Therefore, the controller 13 determines whether hot water is used according to a low or high signal to the input port P 1 . In other words, when the hot water is used, water flows into the water supply pipe 6, and the flow valve 9 detects this and turns on. Therefore, a low signal is input to the input port P 1 of the controller 13. Further, the output port of the control unit (13) (P 2), the inverter 19, diode 20, relay 21 and the gas valve driver 15 made of a gas valve 12 connected to the output port (P 2 The relay 21 is turned on at the high output to the gas valve 12 so that the gas valve 12 is driven (opened).
또한, 출력포트(P3)에는 인버터(22), 다이오드(23), 릴레이(24) 및 삼방변(3)으로 이루어진 삼방변 구동부(16)가 접속되어 온수사용시 출력포트(P3)로하이신호를 출력하여 삼방변(3)을 구동시킴으로서 난방회로를 폐회로로 구성하여 온수사용조건에 부합하도록 한다.In addition, an output port P 3 is connected to a three-way drive unit 16 including an inverter 22, a diode 23, a relay 24, and a three-way side 3 so as to output a high signal to the output port P 3 when hot water is used. By outputting the three-sided (3) to drive the heating circuit to the closed circuit to meet the hot water use conditions.
상기와 같은 구성의 본 고안을 제3도의 흐름도를 참조하여 그 작용을 설명한다.The operation of the present invention having the above configuration will be described with reference to the flowchart of FIG.
본 고안에 따른 장치에 전원(AC) (V1) (V2)이 투입되고 난방작용이 이루어지면, 제어부(13)는 입력포트(P1)로 입력되는 값을 읽어들여 온수사용중인가를 판단한다. 물론 이때의 판단은 플로우밸브(9)의 온, 오프 신호로써 가능하다.When the power (AC) (V 1 ) (V 2 ) is input to the device according to the present invention and the heating is made, the control unit 13 reads the value input to the input port (P 1 ) to determine whether hot water is in use. do. Of course, the determination at this time is possible by the on and off signals of the flow valve 9.
이때 온수사용이 검출되면 정상적인 온수 운전 구동모드로 진행하나, 온수사용이 중단됐음이 검출되면 출력포트(P2)로 가스밸브(12) 구동신호를 출력하되, 최대화력이 유지되도록 출력하며 여기서 최대화력이란 난방수의 온도가 설정된 최대값을 유지할 수 있도록 가스밸브(12)를 온, 오프 제어하는 공지의 기술이다.At this time, if hot water is detected, it proceeds to the normal hot water operation driving mode, but if it is detected that hot water is stopped, the gas valve 12 driving signal is output to the output port (P 2 ), but the output is maintained so as to maximize the power. Thermal power is a well-known technique which controls the gas valve 12 on and off so that the temperature of heating water can maintain the set maximum value.
상기와 같은 출력이 진행된지 2분이 경과되었는가를 판단하여 2분이 도래되면 다시 정상적인 보일러의 운전으로 복귀하는 것이다.It is determined whether 2 minutes have elapsed since the above-described output proceeds, and when 2 minutes arrives, the process returns to normal boiler operation again.
제4도는 본 고안을 적용한 온수의 온도(A)와 종래의 보일러 온수온도(B)를 나타낸 것으로 본 고안의 경우 종래에 비해 훨씬 적은 온도 편차를 보이고 있다.4 shows the temperature (A) of the hot water to which the present invention is applied and the conventional boiler hot water temperature (B), which shows much less temperature deviation than the conventional case.
이상에서와 같이 본 고안은 온수사용시 온수사용을 중단한 후 잠시후 다시 온수사용을 하더라도 찬물이 나오는 현상을 일소한 이점이 있다.As described above, the present invention has the advantage of eliminating the phenomenon of cold water even when using hot water again after stopping the use of hot water when using hot water.
