본 고안은 온수보일러에 있어서, 난방시스템을 장기간 가동하지 않게 되는 하절기에도 일정시간에 잠깐씩 순환펌프를 가동시켜 줌으로써 순환펌프의 정상 가동이 예비되도록 하여 순환펌프의 결속으로 인한 안전사고를 미연에 방지하고, 순환펌프의 수명배가 효과를 얻을 수 있도록 보일러 콘트롤장치의 제어부에 설치되는 순환펌프제어회로에 대한 것으로 본원 출원인이 선고안한 실용원 제 91-9878 호를 개량한 것이다.The present invention prevents safety accidents due to the binding of the circulation pump by allowing the circulation pump to be preliminarily operated by temporarily operating the circulation pump at a predetermined time even in the summer when the heating system does not operate the heating system for a long time. In addition, the circulating pump control circuit is installed in the control unit of the boiler control device so that the life of the circulating pump can be obtained is an improvement of the practical application No. 91-9878 proposed by the applicant.

종래의 보일러 운전방식은 난방시스템으로의 가동시에 한하여 순환펌프의 구동이 이루어지도록 되어 있기 때문에 하절기등과 같이 장기간 동안 보일러 난방시스템을 가동하지 않을 경우에는 장마철을 지나면서 순환펌프의 동력원인 모터 베어링부가 녹이 슬거나 임펠러에 이물질의 누적으로 인한 결속 현상이 생기게 된다.In the conventional boiler operation method, the circulation pump is driven only when the heating system is operated. Therefore, when the boiler heating system is not operated for a long time such as in the summer, the motor bearing is the power source of the circulation pump. Bonding is caused by additional rust or accumulation of foreign matter on the impeller.

그런데 가을철이 되어 갑자기 보일러의 난방시스템을 가동시키게 될 경우, 모터의 결속현상으로 인한 모터의 소손 및 나아가 화재를 방생시키게 되는 문제가 있었다.However, when the heating system of the boiler is suddenly turned on in autumn, there is a problem of generating a burnout of the motor and even a fire caused by the binding of the motor.

본 고안은 상기와 같은 종래의 보일러 운전시스템이 안고 있는 순환펌프의 가동상 문제점을 감안하여 난방시스템을 장기간 가동하지 아니하는 하절기에도 일정주기로 순환펌프의 가동이 이루어질 수 있도록 안출한 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention has been conceived to allow the operation of the circulation pump at regular intervals even in the summer when the heating system is not operated for a long time in consideration of the operational problems of the circulation pump in the conventional boiler operating system as described above. The detailed description is as follows.

제 1 도는 본 고안이 적용되는 온수보일러의 전반적인 운전제어시스템(메인 콘트롤장치)을 간략 도시한 블록 구성도로서, 본 고안은 난방, 취침, 급탕(목욕), 외출기능을 갖는 온수보일러에 적용되며, 본 고안의 결속회로(순환펌프 결속방지회로)는 보일러에 메인 콘트롤장치에 해당하는 제어부내에 설치된다.1 is a block diagram schematically showing the overall operation control system (main control device) of the hot water boiler to which the present invention is applied, and the present invention is applied to a hot water boiler having heating, sleeping, hot water (bath), and outing functions. , The binding circuit (circulation pump binding prevention circuit) of the present invention is installed in the control unit corresponding to the main control device in the boiler.

통상으로 보일러의 운전을 제어하는 콘트롤장치는 크게 제어부와 룸신호 수신부 및 출력부로 구성되며, 상기 룸신호부에서는 실내온도 조절기에서 발사되는 신호를 제어부에 출력하며, 제어부에서는 이 신호를 받아 출력부내 각 유니트를 온/오프시키는 구동부(IT)(EP)(BM)(CP)(AW)로 제어신호를 보내어 각 유니트를 가동시키거나 또는 정지시켜 보일러의 전반적인 운전을 자동 콘트롤 하게 되는 것이다.In general, the control device for controlling the operation of the boiler is largely composed of a control unit, a room signal receiving unit and an output unit, the room signal unit outputs a signal emitted from the room temperature controller to the control unit, the control unit receives this signal in each output unit The control signal is sent to the drive unit (IT) (EP) (BM) (CP) (AW) to turn on / off the unit to start or stop each unit to automatically control the overall operation of the boiler.

제 2 도는 본 고안의 순환펌프 결속방지회로를 상세히 나타낸 회로로써, 본 회로는 보일러의 수실 물온도를 체크하기 위한 감지부(1)와 급탕 운전시 순환펌프를 구동시켜 주기 위한 순환펌프 제어부(2)로 구성되며, 상기 감지부(1)와 순환펌프 제어부(2) 사이에는 다이오드(D2)가 설치되어 있다.2 is a circuit diagram illustrating the circulation pump binding prevention circuit of the present invention in detail. The circuit includes a detector 1 for checking a water temperature of a boiler and a circulation pump controller 2 for driving a circulation pump during hot water operation. And a diode (D 2 ) is provided between the sensing unit (1) and the circulation pump control unit (2).

온도센서와 연결되어 있는 감지부(1)는 다단으로 연결된 비교기(Q1)(Q2)로 구성되되 상기 비교기(Q1)의 +입력단에는 온도센서가 연결되며 그의 -입력단에는 전원분배저항(R1)(R2)이 병렬 연결되어 있으며, 순환펌프 제어부(2)는 입력단이 전원단(Vcc)에 연결된 비교기(Q3)와 저항(R6), 콘덴서(C1)로 구성되는 충전회로와 비교기(Q4)로 이루어지며, 상기한 비교기(Q3)의 +입력단에는 전원 바이패스용 저항(R4)이 연결되며, 다이오드(D2)를 거쳐 비교기(Q2)의 출력단과 연결된다.The sensing unit 1 connected to the temperature sensor is composed of comparators (Q 1 ) (Q 2 ) connected in multiple stages, and a temperature sensor is connected to the + input terminal of the comparator (Q 1 ), and a power distribution resistor ( R 1 ) (R 2 ) are connected in parallel, and the circulation pump control unit 2 is composed of a comparator (Q 3 ), a resistor (R 6 ), and a capacitor (C 1 ) having an input terminal connected to a power supply terminal (Vcc). A circuit and a comparator (Q 4 ), the + input terminal of the comparator (Q 3 ) is connected to the resistor (R 4 ) for the power bypass, and through the diode (D 2 ) and the output terminal of the comparator (Q 2 ) Connected.

비교기(Q3)의 -입력단에는 전원분배저항(R10)(R12)이 병렬 연결되어 있다.A power distribution resistor R 10 (R 12 ) is connected in parallel to the − input terminal of the comparator Q 3 .

It is.

이와 같이 구성되는 본 고안이 작용효과를 설명한다.The present invention constituted as described will be described.

통상 보일러의 운전기능에는 난방기능, 취침기능, 외출기능, 급탕기능의 4가지 시스템으로 구분되며, 난방의 효율적인 가동을 위하여 국내에 적용되는 보일러의 경우는 계절별 난방이 이루어지도록 스위치 기능이 계절에 따라 조절될 수 있도록 되어 있다.Normally, the boiler's operation functions are divided into four systems: heating function, sleeping function, going out function, and hot water supply function. In the case of boilers applied domestically for efficient operation of heating, the switch function is set according to the season according to the season. It can be adjusted.

이와같은 운전시스템의 제어는 메인 콘트롤장치(일명 CTC장치라 함)에서 자동 콘트롤 되는 바, 그 개략적인 구성은 제 1 도에 도시한 바와 같다.The control of such a driving system is automatically controlled by a main control device (also called a CTC device), the schematic configuration of which is shown in FIG.

예를들어 실내온도조절기를 이용하여 급탕기능을 선택하게 되면 해당 신호가 룸신호 수신부를 거쳐 제어부로 입력되면서 급탕시스템으로의 가동신호가 출력부로 출력되어 버어너구동부(BM), 전자펌프구동부(EP), 전화트랜스구동부(IT)가 '온'되어 수실내의 물온도를 85-90℃로 가열 40-60℃의 급탕수를 배출시키게 되는 것이다.For example, when the hot water supply function is selected using the indoor temperature controller, the corresponding signal is input to the control unit through the room signal receiving unit, and the operation signal to the hot water supply system is output to the output unit, and the burner driver BM and the electronic pump driver EP ), The telephone transformer driving unit (IT) is 'on' and the water temperature in the chamber is heated to 85-90 ℃ to discharge hot water of 40-60 ℃.

그런데, 일반 보일러의 운전시스템의 경우는 난방시스템에서는 버어너의 가동과 동시에 순환펌프가 계속 가동되나 급탕시스템에서는 순환펌프가 가동되지 않도록 설계되기 때문에 하절기의 수개월 동안은 순환펌프의 가동이 정지되도록 되어 있으나, 본 고안에서는 급탕시스템으로의 가동시 잠깐 동안 순환펌프의 가동이 이루어지도록 함으로써 순환펌프의 결속을 예방할 수 있도록 한 것이다.However, in the case of the operation system of the general boiler, the circulation pump is continuously operated at the same time as the burner is operated in the heating system, but the circulation pump is not operated in the hot water supply system, so the operation of the circulation pump is stopped during the summer months. However, the present invention is to prevent the binding of the circulating pump by operating the circulating pump for a short time during operation to the hot water supply system.

이를 구체적으로 설명하면, 제 1 도에서 실내 온도조절기로부터 급탕신호가 룸신호수신부로 전달되어 제어부로 급탕신호가 출력되면(급탕 신호의 인식) 제 2 도에 도시된 바와같이 전압(Vcc)이 전원 저항(R4)을 거쳐 다이오드(D2)를 통해 흐름과 동시에 비교기(Q3)의 +입력단으로 '하이' 신호가 입력되게 되므로 그의 출력 역시 '하이'상태가 된다.Specifically, in FIG. 1, when the hot water signal is transmitted from the room temperature controller to the room signal receiver and the hot water signal is output to the control unit (recognition of the hot water signal), the voltage Vcc is applied as shown in FIG. 2. As the current flows through the resistor R 4 and through the diode D 2 , a 'high' signal is input to the + input terminal of the comparator Q 3 , and thus its output is also 'high'.

이 하이신호는 충전회로를 구성하는 콘덴서(C1)와 저항(R6)을 거쳐 다이오드(D3)를 통해 비교기(Q4)의 +입력단으로 입력되어 그의 출력으로 '하이' 신호를 내보내게 되는 관계로 출력부내의 순환펌프 구동부를 '온' 시킬수가 있게 되는 것이다.This high signal is input to the + input terminal of the comparator (Q 4 ) through the diode (D 3 ) through a capacitor (C 1 ) and a resistor (R 6 ) constituting the charging circuit, and emits a 'high' signal to its output. In this regard, the circulation pump driving unit in the output unit can be 'on'.

이때 순환펌프의 가동시간은 충전회로와 RC 시정수에 의해 결정되는데 약 30-40초 동안이 이상적이다.The operating time of the circulation pump is determined by the charging circuit and RC time constant, which is ideal for about 30-40 seconds.

그런데, 본 결속방지회로에서는 룸신호수신부로부터 급탕신호가 인식되더라도 온도센서에서 감지되는 수실내의 물온도가 고온일 경우에는 순환펌프의 일시적 가동이 이루어지지 못하도록 회로가 구성되어 있다.By the way, in this binding prevention circuit, even if a hot water signal is recognized from a room signal receiving part, a circuit is comprised so that a temporary operation of a circulation pump may not be performed when the temperature of the water in a chamber detected by the temperature sensor is high temperature.

즉, 제 2 도 온도센서에서 고온(40℃ 이상)이 감지되면 감지부(1)를 구성하는 비교기(Q1)의 +입력단이 '로우'상태가 되는 관계로 그의 출력이 '로우'가 됨과 동시에 이와 다단으로 연결된 비교기(Q2)의 출력 또한 '로우' 상태가 되어 전원 저항(R4)을 통해 흐르는 전압이 다이오드(D2)를 통해 흘러버리게 되는 관계로 순환펌프 제어부(2)로 구성되는 비교기의 +입력단이 '로우'가 되고 그의 -입력단이 '하이'가 되므로 비교기(Q3)의 출력이 '로우'가 되어 결국 순환펌프는 가동되지가 않는 것이다.That is, when a high temperature (40 ° C. or more) is detected by the temperature sensor of FIG. 2, the output of the comparator Q 1 constituting the sensing unit 1 becomes 'low' because its + input terminal becomes 'low'. At the same time, the output of the comparator Q 2 connected in multiple stages is also in a 'low' state, so that the voltage flowing through the power supply resistor R 4 flows through the diode D 2 . The + input of the comparator becomes 'low' and the-input of its comparator becomes 'high', so the output of the comparator (Q 3 ) becomes 'low' and the circulation pump is not operated.

이와 같이 본 고안에서는 보일러 메인 콘트롤장치의 제어부내에 결속회로를 설치하여 급탕운전시마다 잠시동안 순환펌프이 가동이 이루어지도록 함으로써 장시간 난방을 실시하지 않게 되는 여름철에도 간헐적인 순환펌프의 가동으로 일펠러의 결속을 방지시켜 안전사고를 미연에 방지하고 순환펌프의 수명 배가효과를 얻을 수 있는 것이다.As described above, in the present invention, a binding circuit is installed in the control unit of the boiler main control device so that the circulation pump is operated for a short time every hot water supply operation. It is possible to prevent the safety accident in advance and to double the life of the circulation pump.
