본 발명은 자동물보급 기능을 가진 보일러의 누수 검지 기술에 관한 것으로서, 보다 상세하게는 보일러의 최초 설치가 이루어진 경우 배관내의 공기를 충분히 빼주기 위하여 보일러의 일정가동시간 전에는 누수 검지를 차단하고, 일정가동시간이 경과된 후에 배관의 누수검지 기능을 실시하는 보일러의 시운전에 따른 누수 검지 장치 및 그 검지방법에 관한 것이다.The present invention relates to a leak detection technology of a boiler having an automatic water supply function, and more particularly, to detect a leak before a predetermined operating time of the boiler in order to sufficiently drain the air in the pipe when the boiler is initially installed, The present invention relates to a leak detection apparatus and a detection method according to a test run of a boiler which performs a leak detection function of a pipe after an operation time elapses.

종래 자동물보급 기능을 가진 대부분의 보일러는 전원 투입 후 일정시간(약 5∼7시간)의 통전이 되어야 메모리(EEPROM)에 데이터를 기억하게 되고, 이는 최초 전원 투입 시간이 경과하기 전에 보일러의 모든 설정값이 기본 설정값으로 되어 있기 때문이며, 이것은 보일러 생산시의 값들이 기억되는 것을 방지하기 위한 것으로서, 이것으로 최초 전원투입을 판정하게 된다.Most boilers with automatic water supply function have to be energized for a certain time (approximately 5 to 7 hours) after the power is turned on to store the data in the memory (EEPROM). This is because the set value is the default set value, which is to prevent the values at the time of boiler production from being stored, thereby determining the initial power-on.

그리고, 종래의 보일러는 최초 설치가 이루어질 때, 난방 및 온수측 배관내에 공기가 유입되므로 인해 운전시에 소음 발생 및 열 교환기가 비등되는 것을 방지하기 위해 보일러의 운전스위치를 온시키고, 난방배관내의 물을 강제적으로 보충시킨 다음, 보일러를 시운전시켜 배관내의 공기를 제거하도록 되어 있다.In the conventional boiler, when the first installation is made, air is introduced into the heating and hot water side pipes, and thus, the operation switch of the boiler is turned on to prevent noise and heat exchanger from boiling during operation. Is forced to replenish, and the boiler is commissioned to remove air from the pipes.

그러나, 종래에는 보일러가 최초 설치되어 배관의 설치 상태에 따라 배관내의 공기 제거가 제대로 이루어지지 않을 경우, 보일러의 시운전 후 누수검지시간 이내에 소정횟수 이상의 자동 물보급이 실시될 때 실제 누수가 발생하지 않았는데도 누수 에러가 검지되고, 이에따라 소비자가 누수에러에 대한 점검을 요청하게 되는 불편함이 따랐다.However, conventionally, when the boiler is initially installed and the air in the pipe is not properly removed according to the installation state of the pipe, even when the automatic water supply is performed more than a predetermined number of times within the leak detection time after the boiler is started, no actual leakage occurs. A leak error was detected, and accordingly, the consumer was asked to check for a leak error.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으 로서, 최초 보일러 설치 후 일정시간동안 난방가동시간을 체크하여, 배관내의 공기를 충분히 빼주는 일정가동시간 전에는 누수 검지를 차단하고, 일정가동시간이 경과된 후에 배관의 누수검지 기능이 이루어지도록 하여, 보일러의 설치 초기 배관의 공기빼기가 자주될 때 발생하게 되는 누수 오검지에 따른 소비자 불편사항을 해소할 수 있도록 하는 보일러의 시운전에 따른 누수 검지 장치 및 그 검지방법을 제공하려는데 목적이 있는 것이다.Therefore, the present invention has been made to solve the above-mentioned conventional problems, by checking the heating operation time for a certain time after the initial boiler installation, to block the leak detection before a certain operating time to sufficiently drain the air in the pipe, Leakage detection function of the pipe is made after a certain operating time has elapsed, so that the customer's inconvenience caused by leak leakage detection that occurs when the boiler is frequently drained at the initial stage of boiler installation can be solved. An object of the present invention is to provide a leak detection device and a detection method thereof.

Proceeds.

It proceeds including.

이하, 첨부된 도면에 의하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 실시예로 보일러의 시운전에 따른 누수검지장치의 개략적인 블럭 구성도를 도시한 것으로, 물탱크(10)로 공급되는 물의 만수위를 감지하는 만수위센서(11), 배관에 물이 비었는지 또는 차있는지를 감지하는 저수위센서(12), 물탱크(10)로 물 공급과 차단을 위해 구동하는 수전자변 구동부(13), 상기 수전자변 구동부(13)의 구동으로 온/오프되는 보급수변(14), 누수에러 검출시 경보음을 출력하는 경보부(15), 그리고 타임비교부(16a)와 비교연산부(16b)가 구성되고, 상기 만수위 및 저수위센서(11)(12)로부터 감지된 신호를 통해 수전자변 구동부(13)를 제어함은 물론, 상기 경보부(15)의 구동을 제어하는 하는 제어부(16)로 구성된다.1 is a schematic block diagram of a leak detection apparatus according to a test operation of a boiler according to an embodiment of the present invention, the high water level sensor 11 for detecting the high water level of the water supplied to the water tank 10, water in the pipe Low water level sensor 12 for detecting whether it is empty or full, water receiver 10 for driving the water supply and shut off to the water tank 10, which is turned on / off by the drive of the water heater valve 13 The water supply side 14, an alarm unit 15 for outputting an alarm sound when a leak error is detected, and a time comparison unit 16a and a comparison operation unit 16b are configured and detected from the high water level and low water level sensors 11 and 12. The controller 16 controls the driver's valve driving unit 13 through the received signal, as well as controlling the driving of the alarm unit 15.

이때, 상기 보일러의 시운전에 따른 누수검지장치에 의해 구현되는 누수검지방법을 첨부된 도 1 및 도 2를 참조하여 설명하면 다음과 같다.At this time, a leak detection method implemented by the leak detection apparatus according to the trial operation of the boiler will be described with reference to FIGS. 1 and 2.

먼저, 보일러에 전원이 투입되면, 제어부(16)에서 보일러의 전원통전에 대한 일정시간 경험이 있었는가를 체크하게 된다.First, when power is supplied to the boiler, the controller 16 checks whether there is a certain time experience with the power supply of the boiler.

다음으로, 상기 체크된 전원통전시간이 소정의 시간(약 6시간)동안 지속되었는지를 판단하고, 상기의 판단결과 소정의 시간동안 보일러의 전원통전시간이 지속되는 경우, 상기 타임비교부(16a)와 비교연산부(16b)를 구비한 제어부(16)는 보일러의 난방 누적 가동시간이 소정의 시간(약 24시간)을 경과하였는지를 체크한다.Next, it is determined whether the checked power supply time has lasted for a predetermined time (about 6 hours), and if the power supply time of the boiler lasts for a predetermined time, the time comparison unit 16a And the control unit 16 including the comparison operation unit 16b check whether the heating accumulated operating time of the boiler has passed a predetermined time (about 24 hours).

이때, 상기 제어부(16)는 보일러의 난방 누적 가동시간이 소정의 시간을 경과하지 않을 경우 누수검지 카운터 증가에 대한 판단을 중지하지만, 만약 보일러의 난방 누적 가동시간이 소정의 시간을 경과하였다고 판단될 경우에는 누수검지 카운터 증가에 따른 판단을 실시하게 된다.At this time, the control unit 16 stops the determination of the leakage detection counter increase when the heating cumulative operating time of the boiler does not pass a predetermined time, but it is determined that the heating cumulative operating time of the boiler has passed a predetermined time. In this case, determination is made according to the increase of the leak detection counter.

즉, 보일러의 가동시간 즉, 누수판단을 위한 한정시간(예; 64시간)이 설정된 상태에서, 물탱크(10)의 저수위 상태를 검지하는 저수위센서(12)가 오프되는 경우, 상기 제어부(16)는 수전자변 구동부(13)를 구동시켜 보급수변(14)을 온 시킨다.That is, when the low water level sensor 12 which detects the low water level of the water tank 10 is turned off while the operating time of the boiler, that is, a limited time (eg, 64 hours) for the water leak determination is set, the controller 16 ) Turns on the replenishment stool 14 by driving the receiver receiver 13.

그러면, 상기 보급수변(14)의 온으로부터 물탱크(10)에는 자동 물 보충이 이루어지고, 이때 상기 물탱크(10)에 자동 물 보충이 이루어짐과 동시에 만수위센서(11)에 의해 만수위가 검지되는 경우, 상기 검지된 만수위 정보는 제어부(16)로 전달된다.Then, automatic water replenishment is made to the water tank 10 from the on of the water supply side 14, and at this time, the water level is detected by the high water level sensor 11 at the same time as the automatic water replenishment is made to the water tank 10. In this case, the detected water level information is transmitted to the controller 16.

이에따라, 상기 제어부(16)는 수전자변 구동부(13)를 통해 보급수변(14)을 오프시키게 됨으로써, 보일러의 1차 자동 물보충 공정이 종료되고, 이와동시에 누수 에러 카운터가 시작된다.As a result, the control unit 16 turns off the replenishing water valve 14 through the power receiver valve driving unit 13, thereby ending the first automatic water refilling process of the boiler, and at the same time, the leak error counter starts.

한편, 상기와 같이 1차 물 보충이 이루어진 상태에서, 물탱크(10)의 저수위 상태를 검지하는 저수위센서(12)가 오프되지 않을 경우, 상기 제어부(16)는 누수판단을 위한 보일러의 가동시간, 즉 설정된 한정시간(예; 64시간)을 경과하였는지를 체크하고, 그 체크결과 설정된 시간을 경과한 경우에는 누수 검지 카운터를 초기화시키게 된다.On the other hand, in the state where the primary water replenishment is made as described above, when the low water level sensor 12 for detecting the low water level of the water tank 10 is not turned off, the control unit 16 is operating time of the boiler for the water leakage determination That is, it is checked whether the set time limit (e.g., 64 hours) has elapsed, and when the check result has elapsed, the leak detection counter is initialized.

그러나, 보일러의 가동시간이 설정된 시간을 경과하지 않을 경우, 상기 제어부(16)는 다시 물탱크(10)의 저수위 상태를 검지하는 저수위센서(12)가 오프되었는가를 체크하고, 상기 체크결과 저수위센서(12)가 오프되면 제어부(16)는 자동 물 보급을 실시하면서 누수 에러 카운터를 증가시킨다.However, when the operating time of the boiler does not pass the set time, the controller 16 checks again whether the low water level sensor 12 which detects the low water level state of the water tank 10 is turned off, and the low water level sensor as a result of the check. If (12) is off, the controller 16 increments the leak error counter while performing automatic water replenishment.

이때, 상기 제어부(16)는 상기와 같은 동작흐름을 반복 즉, 소정횟수 이상 반복 실시하여 누수에러의 발생횟수를 체크하게 되며, 만약 카운터되는 누수에러가 소정횟수 이상 반복(예, 3회 정도)되는 경우, 상기 제어부(16)는 누수가 발생하였음을 판정한 후 경보부(15)의 제어를 통해 사용자가 인지할 수 있는 경보음을 외부로 출력하게 되는 것이다.At this time, the control unit 16 repeats the above-described operation flow, that is, repeats a predetermined number of times or more and checks the number of occurrences of the leak error, and if the leaked water that is counted repeats the predetermined number or more (for example, about three times) If the control unit 16 determines that a leak has occurred, the control unit 16 outputs an alarm sound that can be recognized by the user through the control of the alarm unit 15.

이상에서 설명한 바와 같이 본 발명은 최초 보일러 설치 후 일정시간동안 난방가동시간을 체크하여, 배관내의 공기를 충분히 빼주는 일정가동시간 전에는 누수 검지를 차단하고, 일정가동시간이 경과된 후에 배관의 누수검지 기능이 이루어지도록 한 것으로, 이를 통해 보일러의 설치 초기 배관의 공기빼기가 자주될 때 발생하게 되는 누수 오검지에 따른 소비자 불편사항을 해소하면서 제품에 대한 신뢰도를 더욱더 향상시킬 수 있는 것이다.As described above, the present invention checks the heating operation time for a predetermined time after the installation of the first boiler, blocks the leakage detection before the predetermined operation time to sufficiently drain the air in the pipe, and detects the leakage of the pipe after the predetermined operation time has elapsed. This is to be achieved, through which it is possible to further improve the reliability of the product while eliminating consumer inconveniences caused by leak leakage detection that occurs when the initial installation of the boiler is frequently air drained.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와같은 변경은 청구범위 기재의 범위내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
