그런데 종래의 축열식 전기 보일러는 그 제어방식을 기계식 컨트롤방식으로채용함으로써 다른 여러 기능을 복합 또는 안전성 등을 고려한 설계에 매우 제한적이었다.However, the conventional regenerative electric boiler is very limited to the design considering the combination or safety of other functions by adopting the control method as a mechanical control method.

예컨데, 기계식으로 채용됨으로써 고장에 따른 A/S관리가 어렵고, 온도에 따른 정확한 제어가 미흡하는 등의 보일러 자체 기능을 극대화하는데 한계가 있었을 뿐만 아니라 보일러 기능추가에도 제한적일 수 밖에 없었다.For example, by adopting a mechanical system, it was difficult to maximize A / S management due to failure, lack of accurate control according to temperature, and limited to maximizing boiler function.

상술한 설명은 단상전원일때를 기준으로 설명한 것이며, 삼상전원일 경우와 관련된 도면은 도 4와 도 5이다. 전술한 동작과 동일하므로 이에대한 세세한 설명은 피한다.The above description is based on the case of the single-phase power source, and the drawings related to the three-phase power source are FIGS. 4 and 5. Since the same operation as described above, detailed description thereof will be avoided.

이와같이 구성된 본 발명의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effect of the present invention configured as described above in detail.

먼저, 심야전력을 심야전력단자(509)에 견고히 체결하고 일반전기 및 순환펌프 결선을 완료후 누전차단기(501)(502)를 투입한 상태에서 디지털 표시부의 전원(①)스위치를 켜고 운전(②)스위치를 켜면 마이컴(100)이 활성화되면서 이후 보일러는 설정된 온도에 따라 자동운전된다.(축열효과가 가장 좋은 2。C로 기본설정된 상태이다.)First, after tightening the late-night power to the late-night power terminal 509, and complete the connection of the general electric and circulation pump, the earth leakage circuit breaker (501, 502) is turned on, and the power (①) switch on the digital display unit is operated. When the switch is turned on, the microcomputer (100) is activated and the boiler is automatically operated according to the set temperature. (The default value is 2。C with the best heat storage effect.)

상기 설정온도는 디지털방식으로 빠르고 정밀하여 소망하는 정확한 온도까지 설정할 수 있는바 예컨데, 축열조 온도설정은 디지털표시부의 설정버튼④을 누르면 1번이 표시되고 이어 십자리수, 단자리수 상승버튼을 눌러 원하는 수치로 바꾼상태에서 완료버튼을 누르면 축열조 온도설정이 완료되고, 순환펌프 온도설정인 2번이 표시된다. 설정온도는 축열조 온도설정과 동일하다.The set temperature can be quickly and precisely set to the desired temperature by digital method. For example, the heat storage tank temperature can be set by pressing the setting button ④ of the digital display. If you press the Done button in the state changed to, the heat storage tank temperature setting is completed, and the number 2 of the circulation pump temperature setting is displayed. The set temperature is the same as the heat storage tank temperature setting.

이와같이 설정된 상태에서 먼저 축열동작을 살펴보면 설정온도에 따라 마이컴(100)이 그 출력단에 접속된 전자접촉기의 MC1,MC2를 동작시키면 심야전력의 전원이 누전차단기(501)(502)를 거쳐 히터1,2(516)(517)에 인가되어 축열동작이 시작된다.Looking at the heat storage operation in the set state as described above, when the microcomputer 100 operates MC1 and MC2 of the magnetic contactor connected to the output terminal according to the set temperature, the power of the late-night power is passed through the earth leakage breaker 501 and 502 and the heater 1, 2 (516) 517 is applied to start the heat storage operation.

또한, 순환펌프 동작은 설정온도에 따라 마이컴(100)이 그 출력단에 접속된릴레이(508)를 동작시키면 입력전력의 전원으로 순환펌프모터를 가동시키므로 즉 난방동작이 시작되는데, 이때 초기 순환펌프 가동시 설정된 온도에 도달하면 설정된 일정시간동안만 작동하여 난방 및 축열효율을 높인다.In addition, in the circulating pump operation, when the microcomputer 100 operates the relay 508 connected to the output terminal according to the set temperature, the circulating pump motor is operated by the power of the input power, that is, the heating operation is started. When the temperature reaches the set time, it operates only for the set time, increasing heating and heat storage efficiency.

이와같은 난방 및 축열동작중 수위센서(513)의 저수위감지 신호 및 과열센 서(514)의 과열감지신호가 마이컴(100)에 입력되면 마이컴(100)은 전자접촉기의 MC 1,MC2를 오프시켜 축열동작을 정지시킨다. 그리고 저수위 경보시에는 릴레이(508)를 소자시켜 순환펌프를 정지시키는 반면, 과열 경보 동작시에는 과열 경보 해제전까지 순환펌프를 가동시켜 과열된 축열조를 식히는 것이 그 동작상 바람직하다.When the low water level detection signal of the water level sensor 513 and the overheat detection signal of the overheat sensor 514 are input to the microcomputer 100 during the heating and heat storage operation, the microcomputer 100 turns off the MC 1 and MC2 of the magnetic contactor. Stop the heat storage operation. In the low water level alarm, the relay 508 is turned off to stop the circulation pump. In the overheat alarm operation, the circulation pump is operated until the overheat alarm is released to cool the heat storage tank.

여기서, 저수위, 과열경보가 해제되면 자동으로 운전됨은 당연하고, 운전스위치 꺼짐시 축열동작은 정지되며 축열조 동파방지 상태가 되는데, 이때의 동파방지는 축열조 온도가 5。C이하로 떨어질때 히터를 자동으로 가동시켜 10。C까지 상승시킨 것을 지칭한다.Here, it is natural to operate automatically when the low water level and the overheat alarm are released. When the operation switch is turned off, the heat storage operation is stopped and the heat storage tank freeze protection state becomes. When the heat storage tank temperature drops below 5。C, the heater is automatically turned on. It refers to the operation to raise to 10 ° C.

한편, 본 발명은 축열동작중 상기 히터1,2(516)(517)측에 이상여부를 상시 확인할 수 있는데, 이는 C.T측 즉 히터상태검출기((503)(504)에 인가되는 전류에 의한 확인으로 파악할 수 있어 히터의 가동상태 및 교체시기를 쉽게 판단할 수 있는 것이다.On the other hand, the present invention can always check whether the heater 1, 2 (516) 517 side abnormality during the heat storage operation, which is confirmed by the current applied to the CT side, that is, the heater state detector (503) (504) It is possible to easily determine the operating state and replacement time of the heater.

이상에서 살펴본바와 같이 본 발명은 보일러의 각종 기능을 자동으로 컨트롤하는 마이컴 제어방식으로 채용하되, 특히 그 기능조작 및 고장부위별 자기진단기능, 모든 동작을 한눈에 체크할 수 있는 디지털 표시기능을 포함할 뿐만 아니라, 보일러의 핵심인 히터를 감시하여 A/S 발생시 빠른 조치가 가능하는 등의 각종의 기능이 편리하고, 안전성 있도록 설계됨에 따라 A/S 관리에 탁훨하고 보일러 기능을 극대화시킬 수 있는 특징이 있다.As described above, the present invention is adopted as a microcomputer control method that automatically controls various functions of the boiler, and in particular, includes a digital display function that checks all operations at a glance, including its operation and self-diagnostic function. In addition, various functions such as monitoring the heater, which is the core of the boiler, and quick action in the event of A / S occurrence are designed to be convenient and safe, which is excellent for A / S management and maximizes boiler functions. There is this.
