본 발명은 누수 감지 장치를 갖는 온수기에 관한 것이다. 더욱 상세하게는, 온수기 내부의 배관 등이 파열되어 온수기 내로 누수가 발생할 경우 이를 감지하는 장치를 갖는 온수기에 관한 것이다. The present invention relates to a water heater having a leak detection device. More specifically, the present invention relates to a water heater having a device that detects a leak in the water heater due to the rupture of the pipe inside the water heater.

일반적으로 온수기는 입수되는 물의 흐름 또는 유량을 감지하여 가열장치(이하, "버너")를 점화하고, 버너의 열을 열교환기에 의해 온수기 내로 입수되는 물에 전달하여 사용자가 설정한 온도로 온수를 공급한다. In general, a water heater senses the flow or flow of water to ignite a heating device (hereinafter referred to as a "burner"), and transfers the heat of the burner to the water obtained into the water heater by the heat exchanger to supply hot water at a temperature set by a user. do.

도 1에 도시된 바와 같이, 일반적인 온수기는 입수구(10) 측에 설치되어 온수기 내로 입수되는 물의 유량을 조절하는 유량조절밸브(1), 입수되는 물의 유량을 측정하는 유량센서(2), 입수구(10)로 유입된 물의 온도를 측정하는 입수온도센서(3), 입수되는 물을 설정온도로 보낼 수 있도록 버너의 열을 입수된 물에 전달하기 위한 열교환기(4), 열교환기를 빠져나온 물의 온도를 측정하는 출수온도센서(5), 온수기의 제어 상태를 표시하는 표시부(7)를 갖는 제어기(6), 온수기 내부를 차폐하여 부품들을 보호하는 밀폐식의 케이스(8)를 포함한다. 한편, 도면부호 20은 출수구를 나타낸다.As shown in Figure 1, the general water heater is installed on the inlet 10 side flow rate control valve (1) for adjusting the flow rate of water entering into the water heater, flow sensor (2) for measuring the flow rate of the water, inlet ( 10) an inlet temperature sensor (3) for measuring the temperature of the water introduced into the heat exchanger, a heat exchanger (4) for transferring the heat of the burner to the received water so that the incoming water can be sent to a set temperature, and a temperature of the water exiting the heat exchanger A water discharge temperature sensor 5 for measuring the water, a controller 6 having a display unit 7 for displaying the control state of the water heater, and a sealed case 8 for shielding the parts of the water heater to protect the parts. On the other hand, reference numeral 20 denotes a water outlet.

통상, 유량조절밸브(1)는 입수구(10)와 연결되어 항상 개방되어 있으므로, 사용자가 온수를 사용하지 않는 경우에도, 온수기의 구성요소 및 이들을 연결하는 배관 내에는 일정한 수압을 갖는 물이 항상 채워져 있다. In general, since the flow regulating valve 1 is always open because it is connected to the inlet 10, even if the user does not use hot water, water having a constant water pressure is always filled in the components of the water heater and the pipe connecting them. have.

부품의 노후화 등의 원인으로 온수기 내의 배관들 중 일부가 파열된 경우, 입수구(10)를 통해 유입된 물은 압력차에 의해 파열된 배관을 통해 계속 흘러나오게 되므로, 온수기 케이스(8) 내부는 금방 물로 채워지게 된다. 이 경우, 온수기의 부품(예를 들어, 제어기)이 물에 젖어 사용하지 못하게 되는 것은 물론이고, 온수기 케이스(8)의 간극을 통해 물이 외부로 배출될 수도 있다. 장시간 동안 물이 배출될 경우, 온수기가 설치된 공간의 바닥에도 물이 흘러넘치게 되어, 예상치 못한 추가적인 손실이 발생할 수도 있다.If some of the pipes in the water heater are ruptured due to aging of parts, water introduced through the inlet 10 continues to flow through the pipe ruptured by the pressure difference, so that the inside of the water heater case 8 is quickly It will be filled with water. In this case, not only the parts (for example, the controller) of the water heater are wetted with water, but also cannot be used, and water may be discharged to the outside through the gap of the water heater case 8. If the water is discharged for a long time, the water overflows to the bottom of the space where the water heater is installed, which may result in unexpected additional losses.

따라서, 온수기 내부의 배관 등의 파열로 온수기 케이스(8) 내부에 일정한 수위로 물이 채워질 경우, 이를 감지하여 유량조절밸브(1)를 폐쇄하고, 온수기가 가동 중인 경우라면 온수기의 작동을 중지시키는 것이 바람직하다.Therefore, when water is filled at a constant level in the water heater case 8 due to a rupture of the pipe in the water heater, the water flow is detected by closing the flow control valve 1 and stopping the operation of the water heater if the water heater is in operation. It is preferable.

따라서, 본 발명은 상기 사정을 감안하여 발명한 것으로, 온수기 내부의 배관 등의 파열로 온수기 케이스 내부에 일정한 수위로 물이 채워질 경우, 이를 감지하여 유량조절밸브를 폐쇄하고, 온수기가 가동 중인 경우라면 온수기의 작동을 중지시킬 수 있는 온수기를 제공하고자 함에 목적이 있다. Therefore, the present invention has been invented in view of the above circumstances, and if water is filled at a constant level in the water heater case due to a rupture of a pipe, etc. inside the water heater, if the water is closed, the flow control valve is closed and the water heater is in operation. It is an object to provide a water heater that can stop the operation of the water heater.

이하 첨부한 도면을 참조하여 본 발명의 바람직한 실시예에 대한 구성 및 작용을 상세히 설명하면 다음과 같다. 여기서 각 도면의 구성요소들에 대해 참조부호를 부가함에 있어서 동일한 구성요소들에 한해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호로 표기되었음에 유의하여야 한다.Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Here, in adding reference numerals to the elements of each drawing, it should be noted that the same elements are denoted by the same reference numerals as much as possible even if they are shown in different drawings.

도 2는 누수 감지 장치를 갖는 본 발명의 온수기(100)의 구성을 나타내는 도면이다. 2 is a view showing the configuration of the water heater 100 of the present invention having a leak detection device.

상기 온수기는 제어기와 연결된 누수감지장치[예를 들어, 수위감지센서(9; 9a, 9b)]를 갖는다. 도 2의 (a)에 도시된 바와 같이, 상기 수위감지센서(9)는 제어기 내부로부터 온수기 케이스(8)의 바닥을 향해 돌출되고, 온수기 케이스 바닥으로부터는 일정한 이격거리를 유지하는 2개의 수위감지봉(9a, 9b)으로 구성된다. 그러나, 온수기 케이스(8) 내부의 수위를 감지할 수 있는 구성이라면, 이러한 센서 는 다양한 형태로 실시될 수 있다. 예를 들어, 도 2의 (b)에 도시된 바와 같이, 온수기 케이스(8)의 바닥으로부터 일정한 이격거리를 두고 온수기 케이스 벽면에 부착되는 센서로 구성될 수도 있다. The water heater has a leak detection device (for example, a water level sensor 9; 9a, 9b) connected to the controller. As shown in (a) of FIG. 2, the water level sensor 9 protrudes from the inside of the controller toward the bottom of the water heater case 8 and maintains a constant distance from the water heater case bottom. It consists of the rods 9a and 9b. However, if the configuration can detect the water level inside the water heater case 8, such a sensor may be implemented in various forms. For example, as shown in (b) of Figure 2, it may be composed of a sensor attached to the water heater case wall at a predetermined distance from the bottom of the water heater case (8).

상기 누수감지장치는 온수기 내부 배관 등으로부터 물이 누수되어 온수기 케이스(8) 내부에 일정 높이까지 채워진 물을 감지할 수 있는 구성이라면, 상기 개시된 것 외에도 다양한 형태로 실시될 수 있음은 당업자에게 자명하다. If the leak detection device is configured to detect the water is leaked from the water pipe inside the water heater and filled up to a certain height inside the water heater case (8), it will be apparent to those skilled in the art can be implemented in various forms in addition to the above. .

도 3에 도시된 바와 같이, 온수기 내부의 배관 등의 파열로 배관을 통해 물이 배출되어 수위감지센서(9)의 높이까지 채워지게 되면, 2개의 수위감지봉(9a, 9b)은 통전되어 전기적 신호가 제어기(6)로 전달된다. 일정 시간(예를 들어, 약 3초) 동안 계속 이러한 누수가 감지되면, 제어기는 유량조절밸브(1)를 폐쇄하도록 제어한다. 일정시간 동안 계속적으로 누수가 감지될 것을 요하는 것은, 센서의 일시적인 오작동 등의 원인으로 원하지 않는 유량조절밸브(1) 폐쇄를 방지하기 위함이다. 이때, 온수기가 운전 중인 경우라면, 온수기의 작동을 중지하는 명령도 같이 내리게 된다. As shown in FIG. 3, when water is discharged through a pipe such as a pipe in the water heater and filled up to the height of the water level sensor 9, the two water level sensing rods 9a and 9b are energized to be electrically connected. The signal is sent to the controller 6. If such a leak is detected continuously for a certain time (for example, about 3 seconds), the controller controls to close the flow regulating valve 1. It is necessary to continuously detect leaks for a certain time in order to prevent unwanted closing of the flow control valve 1 due to a temporary malfunction of the sensor. At this time, if the water heater is in operation, the command to stop the operation of the water heater is also issued.

유량조절밸브(1)를 폐쇄하게 되면, 더 이상 입수구(10)를 통해 물이 온수기 내부로 들어오지 않고, 이미 온수기 내로 들어온 물이 배출되고 나면 더 이상 물이 배출되지 않는다. When the flow control valve 1 is closed, water no longer enters the water heater through the inlet 10, and water is no longer discharged after the water that has already entered the water heater is discharged.

따라서, 온수기 내의 부품이 물이 젖어 못쓰게 되는 온수기 자체의 손실 및 2차적인 손실이 발생하는 것을 미연에 방지할 수 있다. Therefore, it is possible to prevent the loss of the water heater itself and the secondary loss, in which the parts in the water heater are wetted by water.

도 4는 본 발명의 온수기에서 누수가 감지될 경우 예시적인 제어 방법을 설명하는 흐름도이다. 4 is a flowchart illustrating an exemplary control method when a leak is detected in the water heater of the present invention.

먼저, 수위감지센서(9)로부터 누수가 감지되었는지를 판단한다(S10).First, it is determined whether a leak is detected from the water level sensor 9 (S10).

누수가 감지된 경우, 누수 감지 타이머를 3초로 설정하고, 타이머를 ON 한다(S20).If a leak is detected, the leak detection timer is set to 3 seconds and the timer is turned on (S20).

다음에, 타이머 경과 시간 동안 계속 누수가 감지되었는지를 판단한다(S30). 타이머 경과 시간 동안 계속 누수가 감지되지 않은 경우, 단계 S10으로 돌아간다.Next, it is determined whether leakage is continuously detected during the timer elapsed time (S30). If no leak is detected during the elapsed timer time, the flow returns to step S10.

타이머 경과 시간 동안 계속 누수가 감지된 경우, 유량조절밸브(1)를 폐쇄하고 입력부(7)에 에러를 표시한다(S40).If leakage is continuously detected during the elapsed time of the timer, the flow control valve 1 is closed and an error is displayed on the input unit 7 (S40).

본 발명은 상기 실시예에 한정되지 않고 본 발명의 기술적 요지를 벗어나지 아니하는 범위 내에서 다양하게 수정 또는 변형되어 실시될 수 있음은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 있어서 자명한 것이다.It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
