Description

가스보일러의 온수출탕 제어방법 (A method for controlling a gas boiler in order to output hot water rapidly)A method for controlling a gas boiler in order to output hot water rapidly

본 발명은 가스보일러의 제어방법에 관한 것으로, 특히 온수의 사용을 검지하는 플로우 스위치가 온되면 운전중인 보일러의 순환펌프를 서서히 감속시키켜 열교환된 온수를 신속하게 출탕하는 가스보일러의 온수출탕 제어방법에 관한 것이다.The present invention relates to a control method of a gas boiler, and in particular, when the flow switch detecting the use of hot water is turned on, the circulating pump of a running boiler is gradually decelerated to control the hot water hot water of the gas boiler to quickly tap the heat exchanged hot water. It is about a method.

일반적으로, 가스보일러는 액화석유가스(LPG)나 액화천연가스(LNG) 또는 도시가스를 내부에서 연소시키고, 이 연소과정에서 발생되는 연소열을 이용하여 물을 가열한 후, 가열된 물을 순환펌프를 통해 실내의 난방배관으로 순환시켜 실내를 난방하거나 목용탕 또는 주방으로 공급하는 장치이다.In general, a gas boiler burns liquefied petroleum gas (LPG), liquefied natural gas (LNG), or city gas inside, heats water using combustion heat generated during the combustion process, and then heats the circulated pump. It is a device that circulates through the heating pipe in the room and heats the room or supplies it to the bath or kitchen.

도 4는 상기와 같이 동작하는 가스보일러의 내부구성을 나타낸 정면도로, 본체(200)의 내측에는 가스의 연소열을 이용하여 난방수를 가열하는 연소실(210)이 형성되어 있는데, 이 연소실(210)의 저부에는 유입되는 가스를 연소시키는 버너(211)가 장착되어 있고, 버너(211)의 상부에는 가스의 연소시 발생되는 연소열을 이용하여 난방수를 가열하는 주열교환기(212)가 장착되어 있다.4 is a front view showing the internal structure of the gas boiler operating as described above, the combustion chamber 210 for heating the heating water using the combustion heat of the gas is formed inside the main body 200, the combustion chamber 210 At the bottom of the burner is mounted a burner 211 for burning the incoming gas, and the top of the burner 211 is equipped with a main heat exchanger 212 for heating the heating water using the heat of combustion generated during combustion of the gas.

한편, 본체(200)의 상부에는 가스의 연소에 필요한 공기를 흡입하는 급기구(201)와 연소실(210)의 배기가스를 외부로 배출하는 배기구(202)가 각각 형성되어 있으며, 급기구(201)를 통해 흡입된 공기는 송풍팬(250)에 의해 연소실(210)내로 공급된다.On the other hand, the upper portion of the main body 200 is provided with an air supply port 201 for sucking the air necessary for the combustion of gas and an exhaust port 202 for discharging the exhaust gas of the combustion chamber 210 to the outside, respectively, Air sucked through) is supplied into the combustion chamber 210 by the blowing fan 250.

또한, 버너(211)로 공급되는 가스를 점화시키기 위해 필요한 고전압을 발생하는 점화트랜스(220)가 본체(200)의 내측 배면에 고정되어 있는데, 이 점화트랜스(220)에서 발생된 고전압은 연소실(210)의 일측면에 고정되어 있는 점화플러그(221)로 공급된다.In addition, an ignition transformer 220 that generates a high voltage necessary to ignite the gas supplied to the burner 211 is fixed to the inner rear surface of the main body 200, and the high voltage generated in the ignition transformer 220 is a combustion chamber ( It is supplied to the spark plug 221 fixed to one side of the 210.

한편, 외부의 가스를 버너(211)로 공급하는 가스공급관(207)의 소정부위에는 공급되는 가스량을 제어하는 가스밸브(240)가 장착되어 있으며, 상기 주열교환기(212)에서 가열된 난방수는 보조열교환기(270)로 공급된다. 이 보조열교환기(270)는 직수공급관(205)을 통해 유입되는 직수를 열교환시켜 온수로 변환시킨다.On the other hand, a predetermined portion of the gas supply pipe 207 for supplying the external gas to the burner 211 is equipped with a gas valve 240 for controlling the amount of gas supplied, the heating water heated in the main heat exchanger 212 is Supplied to the auxiliary heat exchanger (270). The auxiliary heat exchanger 270 exchanges the direct water introduced through the direct water supply pipe 205 and converts it into hot water.

또한, 보조열교환기(270)로 공급된 난방수와 직수는 순환펌프(260)의 구동에 따라 난방수 공급관(203)을 통해 실내의 난방배관으로 공급되거나 열교환되어 온수 공급관(204)을 통해 목용탕이나 주방으로 공급되고, 실내의 난방배관을 통과한 난방수는 난방수 환수관(206)을 통해 물탱크(240)로 환수되는데, 이러한 모든 동작은 제어회로부(230)에 의해 제어된다.In addition, the heating water and the direct water supplied to the subsidiary heat exchanger 270 are supplied to the heating pipe of the room through the heating water supply pipe 203 or heat exchanged according to the operation of the circulation pump 260, and the heat is supplied through the hot water supply pipe 204. The heating water supplied to the molten metal or the kitchen and passed through the heating pipe of the room is returned to the water tank 240 through the heating water return pipe 206, and all these operations are controlled by the control circuit unit 230.

즉, 제어회로부(230)는 가스보일러가 구동되면 순환펌프(260)를 정회전시켜 주열교환기(212)에서 가열된 난방수를 실내의 난방배관으로 출탕하지만 사용자가 온수를 사용하면 순환펌프(260)를 역회전시켜 보조열교환기(270)에서 열교환된 온수를 목욕탕이나 주방으로 공급한다.That is, the control circuit unit 230 rotates the circulation pump 260 forward when the gas boiler is driven to tap the heated water heated in the main heat exchanger 212 to the heating pipe in the room, but when the user uses hot water, the circulation pump 260. Reverse rotation to supply hot water heat exchanged in the auxiliary heat exchanger 270 to the bathroom or kitchen.

다시말해, 도 5에 도시된 것처럼 보일러가 운전중인 상태에서 사용자가 온수를 사용하기 위해 수도꼭지를 틀면 직수공급관(205)을 통해 직수가 보조열교환기(270)로 공급된다(301). 이에따라, 직수공급관(205)의 소정위치에 장착된 플로우 스위치(290)는 온상태로 절환된다(302).In other words, when the user turns on the faucet for using hot water while the boiler is in operation as shown in FIG. 5, the direct water is supplied to the auxiliary heat exchanger 270 through the direct water supply pipe 205. Accordingly, the flow switch 290 mounted at the predetermined position of the water supply pipe 205 is switched to the on state (302).

상기와 같이 직수의 공급으로 플로우 스위치(290)가 스위칭된 후, 소정시간 예를들어 3초동안 온상태를 유지하면 제어회로부(230)는 순환펌프(260)를 도 6에 도시된 것처럼 서서히 감속시켜 정지시키고(303 내지 305), 가스밸브(240)를 폐쇄하여 난방동작을 종료한다(305 내지 306). 이와같이 버너가 소화되어 보일러의 난방동작이 종료되면 제어회로부(230)는 온수를 공급하기 위해 버너를 재점화시키고 순환펌프(260)를 역회전시킨다(307).After the flow switch 290 is switched by the supply of water as described above, the control circuit 230 slowly decelerates the circulating pump 260 as shown in FIG. To stop (303 to 305), and close the gas valve 240 to end the heating operation (305 to 306). As such, when the burner is extinguished and the heating operation of the boiler is finished, the control circuit 230 re-ignites the burner to supply hot water and reversely rotates the circulation pump 260 (307).

그러나, 상기와 같이 직수의 유입에 따라 스위칭되는 플로우 스위치가 3초동안 온상태를 유지하는 것을 확인한 이후에 순환펌프를 감속시키는 경우에는 그 만큼 온수의 출탕속도가 늦어진다는 문제점이 있었다.However, if the flow pump is decelerated after confirming that the flow switch switched according to the inflow of the direct water maintains the on state for 3 seconds, the hot water tapping rate is slowed by that much.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 온수의 사용을 검지하는 플로우 스위치가 스위칭되면 바로 운전중인 보일러의 순환펌프를 서서히 감속시키켜 열교환된 온수를 신속하게 출탕하는 가스보일러의 온수출탕 제어방법을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been invented to solve the above problems, and when the flow switch to detect the use of hot water is switched, the gas boiler for quickly tapping the heat exchanged hot water by slowly decelerating the circulating pump of the boiler in operation. It is an object of the present invention to provide a hot water tapping control method.

상기와 같은 목적을 달성하기 위하여 본 발명은, 가스보일러의 제어방법에 있어서, 온수의 사용을 검지하는 플로우 스위치가 온되면 운전중인 보일러의 순환펌프를 서서히 감속시키는 제 1 단계와, 상기 제1 단계에서 플로우 스위치가 소정의 시간내에 오프상태로 복귀하면 순환펌프를 고속으로 회전시켜 난방동작을 유지하는 제 2 단계와, 상기 제 1 단계에서 플로우 스위치의 온상태가 소정의 시간동안 지속되면 순환펌프를 정지시키고 가스밸브를 폐쇄시켜 버너를 소화시킨 후, 온수공급을 위해 버너를 재점화시키는 제 3 단계를 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention, in the gas boiler control method, the first step of slowly decelerating the circulating pump of the boiler in operation when the flow switch to detect the use of hot water, and the first step The second step of maintaining the heating operation by rotating the circulation pump at high speed when the flow switch returns to the off state within a predetermined time, and the circulating pump when the on state of the flow switch is maintained for a predetermined time in the first step. After stopping and closing the gas valve to extinguish the burner, a third step of re-igniting the burner for hot water supply is provided.
