Description

보일러의 온수대기시간 자동 결정장치{Automatical determination apparatus of hot water waiting time in boiler}Automatic determination apparatus of hot water waiting time in boiler}

본 발명은 순간식 보일러의 온수출탕 속도 개선을 위한 기술에 관한 것으로, 보다 상세하게는 보일러 내부에 장착된 유수감지부에서 발생하는 온/오프 신호를 입력받아 중앙처리장치에서 시간을 계산하여 온수 대기시간을 스스로 결정하는 보일러의 온수대기시간 자동 결정장치에 관한 것이다.The present invention relates to a technique for improving the hot water tapping speed of an instant boiler, and more particularly, by inputting an on / off signal generated from the oil / water detection unit installed inside the boiler to calculate a time in a central processing unit. The present invention relates to a device for automatically determining a hot water standby time of a boiler that determines a standby time by itself.

종래 순간식 보일러의 경우에는 메인 제어기에 미리 설정된 대기시간 후에 더 이상 유수감지 신호가 검출되지 않으면 난방/온수 전환 모터를 난방라인으로 전환한다. In the case of the conventional instantaneous boiler, if no water flow detection signal is detected after a preset waiting time in the main controller, the heating / hot water switching motor is switched to the heating line.

그러나, 이러한 종래 보일러에서는 정해진 시간 후에 온수를 재사용할 경우에 점화 재시도를 위한 프리퍼지(Pre-purge)에 따른 시간지연과 삼방모터의 온수라인 전환을 위한 모터 회전시간으로 인하여 온수 출탕 속도가 느려지고, 또한 온수 출탕대기로 인해 순환펌프와 공기 급기팬이 회전하므로 불필요한 에너지를 초래하게 되는 문제점이 있다.However, in such a conventional boiler, when hot water is reused after a predetermined time, the hot water tapping speed becomes slow due to a time delay caused by pre-purge for re-ignition and a motor rotation time for switching the three-way motor to a hot water line. In addition, since the circulation pump and the air supply fan rotate due to the hot water tap air, there is a problem that causes unnecessary energy.

먼저, 사용자가 온수를 사용하면(단계 S1), 유수스위치가 온상태로 되고 삼방변이 온수로 전환된다(단계 S2~S3).First, when the user uses hot water (step S1), the water flow switch is turned on and the three-way side is switched to hot water (steps S2 to S3).

그후, 중앙처리장치(10)는 온도센서 입력부(12)로부터 온수 온도(Tw)를 입력받아 온수 온도(Tw)가 설정온도 이상인지를 판단한다(단계 S4).Thereafter, the central processing unit 10 receives the hot water temperature Tw from the temperature sensor input unit 12 and determines whether the hot water temperature Tw is equal to or higher than the set temperature (step S4).

상기 단계 S4에서 설정온도 이상으로 판단되면 중앙처리장치(10)는 비례제어에 의하여 온수를 가열제어한다(단계 S5).If it is determined in step S4 that the set temperature or more, the central processing unit 10 controls the heating of hot water by proportional control (step S5).

한편, 상기 단계 S4에서 설정온도 미만으로 판단되면 중앙처리장치(10)는 최대연소 제어에 의하여 온수를 가열제어한다(단계 S6).On the other hand, when it is determined that the temperature is less than the set temperature in step S4, the central processing unit 10 controls the heating of the hot water by the maximum combustion control (step S6).

그후, 중앙처리장치(10)는 온도센서 입력부(12)로부터 입력되는 온수 온도(Tw)가 과열온도 이상인지를 판단하여(단계 S7), 과열온도 이상이면 연소를 중지하도록 제어한다(단계 S8).Thereafter, the central processing unit 10 determines whether the hot water temperature Tw input from the temperature sensor input unit 12 is greater than or equal to the overheating temperature (step S7), and controls to stop the combustion if it is greater than the overheating temperature (step S8). .

한편, 상기 단계 S7의 판단에서 과열온도 이상이 아닌 것으로 판단되면, 중앙처리장치(10)는 비례제어에 의하여 온수를 가열제어한다(단계 S9).On the other hand, if it is determined that the overheating temperature is not higher than the determination in step S7, the central processing unit 10 controls the heating of the hot water by proportional control (step S9).

그후, 중앙처리장치(10)는 사용자가 온수의 사용을 정지함에 따라 유수스위치가 오프상태로 되는지를 확인하여(단계 S10), 유수스위치가 오프상태로 되지 않은 것으로 확인되면 상기한 단계 S7로 진행하고, 유수스위치가 오프상태로 된 것으로 확인되면 상기한 단계 S2에서 유수스위치가 온상태로 된 후에 상기 유수스위치가 오프상태로 된 때까지의 시간(온수사용시간)을 메모리장치(14)에 저장한다.Thereafter, the central processing unit 10 checks whether the water flow switch is turned off as the user stops using the hot water (step S10), and when it is confirmed that the water flow switch is not turned off, the flow proceeds to step S7. If it is confirmed that the water flow switch is turned off, the time (hot water usage time) until the water flow switch is turned off after the flow water switch is turned on in step S2 is stored in the memory device 14. do.

이어, 중앙처리장치(10)는 메모리장치(14)에 저장된 최근 온수사용시간(ONSU1)이 설정시간(Ts) 이하인지를 확인한다(단계 S11).Subsequently, the central processing unit 10 checks whether the latest hot water use time ONSU1 stored in the memory device 14 is less than or equal to the set time Ts (step S11).

상기 단계 S11에서 최근 온수사용시간(ONSU1)이 설정시간(Ts) 이하인 것으로 확인되면 중앙처리장치(10)는 온수대기시간을 제조사에 의하여 설정된 디폴트값으로 설정한다(단계 S12).If it is confirmed in step S11 that the latest hot water use time ONSU1 is less than or equal to the set time Ts, the central processing unit 10 sets the hot water standby time to a default value set by the manufacturer (step S12).

한편, 단계 S11에서 최근 온수사용시간(ONSU1)이 설정시간(Ts)보다 긴 것으로 확인되면 중앙처리장치(10)는 메모리장치(14)에 저장된 최근 온수사용시간(ONSU1) 직전의 온수사용시간(ONSU2)이 1초 이상이고 설정시간(Ts) 이하인지를 확인한다(단계 S13).On the other hand, when it is determined in step S11 that the latest hot water use time ONSU1 is longer than the set time Ts, the central processing unit 10 performs the hot water use time immediately before the latest hot water use time ONSU1 stored in the memory device 14 ( ONSU2) is checked for 1 second or more and less than the set time Ts (step S13).

상기 단계 S13에서 최근 온수사용시간(ONSU1) 직전의 온수사용시간(ONSU2)이 1 초이상이고 설정시간(Ts) 이하인 것으로 확인되면 중앙처리장치(10)는 온수대기시간을 제조사에 의하여 설정된 디폴트값으로 설정한다(단계 S12).In step S13, if it is determined that the hot water use time ONSU2 immediately before the latest hot water use time ONSU1 is 1 second or more and less than the set time Ts, the central processing unit 10 sets the hot water standby time by the manufacturer. (Step S12).

한편, 상기 단계 S13에서 최근 온수사용시간(ONSU1) 직전의 온수사용시간(ONSU2)이 1 초이상이고 설정시간(Ts) 이하가 아닌 것으로 확인되면 중앙처리장치(10)는 온수대기시간을 최근 온수사용시간과 직전 온수사용시간의 평균값에 가중치(본 실시예에서는 60초)를 가산한 시간을 온수대기시간으로 설정한다(단계 S14).On the other hand, if it is confirmed in step S13 that the hot water use time ONSU2 immediately before the latest hot water use time ONSU1 is not less than 1 second and not less than the set time Ts, the central processing unit 10 sets the hot water standby time to the latest hot water. The time obtained by adding the weight (60 seconds in the present embodiment) to the average value of the use time and the immediately preceding hot water use time is set as the hot water standby time (step S14).

한편, 본 실시예에서는 최근의 2회의 온수사용시간만을 사용하였지만 그 이상의 온수사용시간을 사용하여도 된다. 이 경우에는 최근 온수사용 시간의 평균값에 가중치를 가산한 시간을 온수대기시간으로 설정하면 된다.On the other hand, in the present embodiment, only the hot water use time of the last two times is used, but more hot water use time may be used. In this case, the time obtained by adding a weight to the average value of the recent hot water use time may be set as the hot water standby time.

이상 설명한 바와 같이 본 발명에 의하면, 중앙처리장치에서 사용자의 온수사용에 따른 유수감지부의 온/오프 시간을 입력받아 메모리장치에 저장해놓고서 온수대기 시간을 사용자의 온수사용 패턴에 따라 결정하도록 함으로써 온수 출탕 속도가 느려지는 것을 방지하고 또한 불필요한 에너지 소비를 줄일 수 있게 된다. 또한 동절기 난방효율도 높일 수 있게 된다.As described above, according to the present invention, the central processing unit receives the on / off time of the oil / water detection unit according to the user's use of hot water and stores it in the memory device to determine the hot water standby time according to the user's hot water use pattern. This can prevent slowing down and reduce unnecessary energy consumption. In addition, the heating efficiency in winter can be improved.
