위와 같이 이루어진 본 실시예의 작동을 도 3에 도시된 본 발명에 의한 온수기의 온수 제어방법을 설명하기 위한 흐름도를 참조하여 설명하면 다음과 같다.Referring to the flow chart for explaining the hot water control method of the water heater according to the present invention shown in Figure 3 the operation of the embodiment made as described above are as follows.
이와 같이 지속적으로 보일러를 제어하는 메인 콘트롤러(27)에서 유량센서(22)와, 직수온도센서(23)와, 출구온도센서(25)와, 흐름스위치(21)의 신호 값들을 항상 입력받을 뿐만 아니라 온수온도 조절기(30)와 통신하여 온수 온도 조절기(30)에서 입력되는 설정 온도 값이나 보일러의 작동을 제어하기 위한 신호들을 입력받는다.As such, the main controller 27 continuously controlling the boiler receives the signal values of the flow sensor 22, the direct temperature sensor 23, the outlet temperature sensor 25, and the flow switch 21 at all times. Rather, it communicates with the hot water temperature controller 30 to receive a set temperature value input from the hot water temperature controller 30 or signals for controlling the operation of the boiler.
소비자가 온수를 사용하게 되면 메인 콘트롤러(27)에서 유량센서(22)에 이상이 발생했는지를 판단하는데(S10), 이때 유량 센서(22)에 이상이 발생하면 온수온도 조절기(30)에 유량 센서 이상 상태를 표시하게 되고(S20), 온수온도 조절기(30)에 이상상태가 표시되면 사용자가 메인 콘트롤러(27)에 설치된 비상작동 스위치 (28)를 ON 시키게 된다(S30).When the consumer uses hot water, the main controller 27 determines whether an abnormality has occurred in the flow sensor 22 (S10). At this time, if an abnormality occurs in the flow sensor 22, the flow sensor in the hot water temperature controller 30 is used. If the abnormal state is displayed (S20), and the abnormal state is displayed on the hot water temperature controller 30, the user turns on the emergency operation switch 28 installed in the main controller 27 (S30).
이어서, 비상 작동스위치가(28) ON되면 흐름 스위치에서 온수의 흐름 있는지 여부를 판단하여 흐름 스위치(21)에서 온수의 흐름이 감지되지 않으면 온수기의 작동을 중지시키고, 흐름스위치에 온수의 흐름이 감지되면(S40) 직수온도센서(23)에 의해 감지된 직수의 온도와, 출구온도센서에서 감지된 온수의 온도가 메인 콘트롤러(27)에 입력되고, 온수 온도 조절기(30)와 통신하여 입력받은 온수의 설정온도가 메인 콘트롤러(27)에 입력되고, 입력된 직수온도, 출수온도, 설정온도에 따라 온도 비례 제어 공식에 의해 필요열량을 계산(S50)하여 온수를 공급(S60)하게 된다.Subsequently, when the emergency operation switch 28 is ON, it is determined whether the flow of hot water flows from the flow switch. If the flow of hot water is not detected by the flow switch 21, the operation of the water heater is stopped, and the flow of hot water is detected by the flow switch. When (S40) the temperature of the direct water detected by the direct water temperature sensor 23, the temperature of the hot water detected by the outlet temperature sensor is input to the main controller 27, the hot water received by communicating with the hot water temperature controller 30 The set temperature of is input to the main controller 27, the required heat quantity is calculated by the temperature proportional control formula according to the input direct water temperature, the output water temperature, the set temperature (S50) to supply hot water (S60).
소비자가 온수 사용시 유량센서(22)에 이상이 발생하지 않으면 일반적인 온수 공급 상태로 유량 센서(22)에 감지된 유량과, 직수온도센서(24)에 의해 감지된 직수의 온도와, 출구온도센서(25)에서 감지된 온수의 온도가 콘트롤러에 입력되고, 온수온도 조절기(30)와 통신하여 입력받은 온수의 설정온도가 메인 콘트롤러(27)에 입력된 유량, 직수온도, 출수온도, 설정온도에 따라 필요열량을 계산(S70)하여 온수를 공급하게 된다.If the consumer does not have an abnormality in the flow sensor 22 when using hot water, the flow rate detected by the flow sensor 22 in a general hot water supply state, the temperature of the direct water detected by the direct water temperature sensor 24, and the outlet temperature sensor ( The temperature of the hot water detected in 25) is input to the controller, and the set temperature of the hot water received by communicating with the hot water temperature controller 30 depends on the flow rate, direct water temperature, hot water temperature, and the set temperature input to the main controller 27. The required amount of heat is calculated (S70) to supply hot water.
상기한 바와 같이 본 발명은 온수기 및 그의 제어방법에 관한 것으로서, 온수기의 메인 콘트롤러에 비상작동 스위치를 설치하여 온수기의 유량센서에 이상이 발생하면 비상 작동스위치를 작동시켜 유량 센서에 관계없이 흐름스위치에서 온수 흐름을 감지하여 메인 콘트롤러에 전달함으로써 출구온도, 직수 온도 및 설정 온도에 따라 출구온도를 설정온도에 도달하도록 온도비례제어 공식에 의해 온수기를 제어하여 온수기의 유량센서에 이상이 발생하더라도 소비자가 A/S 조치를 받을 때까지 온수를 공급받을 수 있는 이점이 있다.As described above, the present invention relates to a water heater and a control method thereof. When an emergency operation switch is installed in the main controller of the water heater and an abnormality occurs in the flow sensor of the water heater, the emergency operation switch is operated so that the flow switch is independent of the flow sensor. By detecting the hot water flow and delivering it to the main controller, the water heater is controlled by the temperature proportional control formula so that the outlet temperature reaches the set temperature according to the outlet temperature, direct water temperature and the set temperature. There is an advantage to receiving hot water until the / S action.
