일반적으로 가스보일러는 가스를 연료로 이용하여 연소시키고, 이 연소과정에서 발생되는 열을 이용하여 물을 가열하고, 이 가열된 물을 실내의 난방배관을 따라서 순환시켜 난방을 하고 또한 목욕탕, 싱크대 등에 온수를 공급하는 기능을 구비하고 있다.Generally, a gas boiler uses gas as a fuel to burn water, uses the heat generated in the combustion process to heat the water, circulates the heated water along the heating pipe in the room, And a function of supplying hot water.
상기 기능을 하는 가스보일러중에는 난방수을 순환시키기 위해서 양방향순환펌프를 이용하는 것이 있는데 도 1은 양방향 순환펌프를 이용하는 종래 가스보일러의 개략적인 구성도이다.In order to circulate heating water, a bi-directional circulation pump is used in the gas boiler having the above function. FIG. 1 is a schematic view of a conventional gas boiler using a bi-directional circulation pump.
도시된 바와 같이 가스보일러는 외부의 가스가 유입되는 가스유입관(1), 상기 가스유입관(1)상에 설치된 것으로서 버너로 공급되는 가스의 압력을 조절하는 가스밸브(2), 상기 가스유입관(1)을 통해서 유입된 가스와 공기를 혼합하여 연소하는 버너(3), 연소된 배기가스를 배출시키는 연도(4), 그리고 버너(3)로 공기를 흡입시킴과 동시에 연도의 배기가스를 강제배출시키는 배기팬(5)를 포함하고 있다.As shown in the figure, the gas boiler includes a gas inlet pipe 1 through which an external gas flows, a gas valve 2 installed on the gas inlet pipe 1 for regulating the pressure of gas supplied to the burner, A burner 3 for burning and mixing gas and air introduced through the pipe 1, a flue 4 for discharging the burned exhaust gas, and a burner 3, and at the same time, And an exhaust fan 5 for forced discharge.
또한 상기 가스보일러는 난방을 행하는 실내의 난방배관(미도시)으로 부터의 난방수가 환수되는 난방환수관(6), 난방환수관(6)상에 설치된 것으로서 복귀하는 난방수를 일시 저장하는 물탱크(7), 난방수를 순환시키고 난방 및 온수사용시 난방수의 흐름을 선택, 변경하는 양방향 순환펌프(8), 난방수를 가열하는 열교환기(9), 가열된 난방수를 난방배관으로 공급하는 난방수공급관(10), 난방수를 보충하는 물보충관(11),상기 물보충관(11)상에 설치된 자동보충수밸브(12), 온수사용시 직수를 열교환기(9)로 공급하는 직수공급관(13), 열교환기에서 가열된 온수를 배출하는 온수공급관(14), 그리고 온수사용시 직수의 흐름을 감지하는 플로우스위치(flow switch)(15)가 구성되어 있다.In addition, the gas boiler is provided with a heating water return pipe 6, a heating water return pipe 6, and a water tank (not shown) for temporarily storing the heating water returning from the heating water pipe 6, A bidirectional circulation pump 8 for circulating the heating water and selecting and changing the flow of heating water in the case of using heating and hot water, a heat exchanger 9 for heating the heating water, A water replenishment pipe 11 for replenishing the heating water, an automatic replenishing water valve 12 provided on the water replenishing pipe 11, a direct water supply pipe 12 for supplying direct water to the heat exchanger 9 when hot water is used, A supply pipe 13, a hot water supply pipe 14 for discharging hot water heated in the heat exchanger, and a flow switch 15 for sensing the flow of direct water when hot water is used.
또한 양방향 순환펌프(8)의 어느 한 배출구(8a)와 물탱크(7)사이에는 우회관(16)이 연결되어 있으며, 물탱크와(7)와 열교환기(9)사이에는 유입관(17)이 연결되어 있고, 열교환기(9)와 양방향 순환펌프(8)의 유입구(8b)사이에는 유출관(18)이 설치되어 있다. 그리고 상기 난방수공급관(10)은 양방향 순환펌프(8)의 다른 배출구(8c)에 연결되어 있다.A waste pipe 16 is connected between a discharge port 8a of the bidirectional circulation pump 8 and the water tank 7 and an inlet pipe 17 is connected between the water tank 7 and the heat exchanger 9, And an outlet pipe 18 is provided between the heat exchanger 9 and the inlet 8b of the bidirectional circulation pump 8. [ The heating water supply pipe (10) is connected to another outlet (8c) of the bidirectional circulation pump (8).
양방향 순환펌프(8)는 그 회전방향에 따라서 난방수의 배출방향을 달리 하는 것으로서, 그 구조에 대해서는 본출원인이 이미 1996년 4월 29일에 특허출원(출원번호:제96-13427호)을 한바 있으므로 이에 대한 구체적인 설명은 생략하기로 한다.The bidirectional circulation pump 8 differs in the discharge direction of the heating water in accordance with the direction of rotation. The structure of the bidirectional circulation pump 8 has already been proposed by the present applicant on April 29, 1996 (Application No. 96-13427) Therefore, a detailed description thereof will be omitted.
상기와 같이 양방향 순환펌프(8)를 이용하는 가스보일러는 다음과 같이 작용한다.The gas boiler using the bidirectional circulation pump 8 as described above functions as follows.
난방환수관(6)을 통해서 환수되는 난방수는 양방향 순환펌프(8)에 의해서 물탱크(7)와 유입관(17)을 통해서 열교환기(9)로 들어가고, 열교환기(9)에서 가열된 난방수는 유출관(18), 순환펌프(8) 및 난방수공급관(10)을 통하여 각방의 난방배관으로 공급된다.The heating water circulated through the heating water return pipe 6 is introduced into the heat exchanger 9 through the water tank 7 and the inlet pipe 17 by the bidirectional circulation pump 8 and is heated by the heat exchanger 9 The heating water is supplied to each of the heating pipes through the outlet pipe 18, the circulation pump 8 and the heating water supply pipe 10.
이때 양방향 순환펌프(8)는 우회관(16)쪽의 배출구(8a)를 막고 난방수공급관(10)쪽의 배출구(8c)를 열어서 난방수를 난방수공급관(10)쪽으로 공급한다.At this time, the bidirectional circulation pump 8 closes the discharge port 8a on the side of the right pipe 16 and opens the discharge port 8c on the side of the heating water supply pipe 10 to supply the heating water to the heating water supply pipe 10 side.
그리고, 온수사용시에 난방수는 온수와의 열교환효율을 높이기 위해서 각방의 난방배관으로 흐르지 않고 보일러내부에서만 순환하도록 되어 있다.When hot water is used, the heating water is circulated in the boiler without flowing into each heating pipe in order to increase heat exchange efficiency with hot water.
즉 온수사용시에는 양방향 순환펌프(8)의 회전방향이 바뀌도록 되어 있는데 이 경우에 양방향 순환펌프(8)는 우회관(16)쪽의 배출구(8a)를 열고 난방수공급관(10)쪽의 배출구(8c)를 막아서 난방수를 우회관(16)쪽으로 공급한다.In this case, the bidirectional circulation pump 8 opens the discharge port 8a on the side of the right side pipe 16 and the discharge port 8a on the side of the heating water supply pipe 10 in the direction of rotation of the bidirectional circulation pump 8, (8c) to supply the heating water to the right tube (16).
따라서 난방수는 열교환기(9), 유출관(18), 순환펌프(8), 우회관(16) 및 유입관(17)으로 이루어지는 통로를 순환한다.Therefore, the heating water circulates through the passages composed of the heat exchanger 9, the outlet pipe 18, the circulation pump 8, the right pipe 16 and the inlet pipe 17.
이와 같이 가스보일러는 난방과 온수사용을 가능하게 되어있는데 온수사용, 즉 직수공급관(13)에 직수가 흐르는 상태는 플로우스위치(15)에서 감지하고, 난방수의 흐름전환은 전술한 바와 같이 플로우스위치(15)의 온수사용상태감지에 따라 회전방향이 변경되는 순환펌프(8)에 의해서 이루어진다.As described above, the gas boiler is capable of heating and using hot water. The use of hot water, that is, the state in which the direct water flows into the direct water supply pipe 13, is detected by the flow switch 15, (8) in which the direction of rotation is changed according to the detection of the hot water use condition of the water heater (15).
한편, 난방배관의 난방수의 양은 증발 등의 원인에 의해서 조금씩 감소하는데 난방수의 양이 일정수준이상으로 감소하면 물탱크(7)내의 플로트스위치(float switch)(7a)가 이를 감지하여 자동보충수밸브(12)를 개방시킨다. 자동보충수밸브(12)가 개방되면 난방배관에 물이 보충되는데 물이 일정수준 보충되면 플로트스위치(7a)가 다시 이를 감지하여 자동보충수밸브(12)를 닫는다.On the other hand, the amount of heating water in the heating pipe is gradually decreased due to evaporation or the like. When the amount of heating water is decreased to a certain level or more, the float switch 7a in the water tank 7 senses it, The water valve 12 is opened. When the automatic replenishing water valve 12 is opened, water is replenished to the heating pipe. When the water is replenished to a certain level, the float switch 7a senses it again and closes the automatic replenishing water valve 12.
상기와 같이 종래의 가스보일러는 온수사용을 감지하는 플로우스위치(15)와 난방수를 보충하는 자동보충수밸브(12)는 서로 연관이 됨이 없이 독립적으로 구성되어 있고 각각 독립적으로 작동되도록 되어 있다.As described above, in the conventional gas boiler, the flow switch 15 for sensing the use of hot water and the automatic replenishing water valve 12 for replenishing the heating water are independently constructed without being related to each other, and are operated independently of each other .
따라서 종래의 가스보일러는 보일러내부의 배관구조가 복잡하고 조립작업이 그 만큼 힘이 들어 조립시간이 많이 소요되며, 그에 따라 제조단가가 상승하는 문제점이 있었다.Accordingly, the conventional gas boiler has a complicated piping structure inside the boiler and requires a lot of assembly time due to the assembly operation, which increases manufacturing cost.
또한 배관연결부의 개소가 많아 잦은 누설이 발생하는 불량이 발생하는 문제점도 있었다.In addition, there are problems that frequent leakage occurs due to a large number of pipe connection portions.
본 발명은 전술한 종래 기술의 문제점을 해결하기 위해서 안출된 것으로서, 플로우스위치와 자동보충수밸브를 한곳에 집중시키고 이들 부품을 열교환기에 직접 연결토록 함으로써 배관구조를 단순화하고 조립작업을 원활하게 하며, 배관연결부의 개소를 감소시켜 그 만큼 물의 누설가능성을 감소시키도록 한 가스보일러의 플로우스위치 및 자동보충수밸브의 열교환기연결구조를 제공하는 것을 그 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art described above, and it is an object of the present invention to provide a flow control device and a control method thereof, in which the flow switch and the automatic replenishing water valve are concentrated in one place, And it is an object of the present invention to provide a heat exchanger connecting structure of a flow switch of a gas boiler and an automatic replenishing water valve which reduces the possibility of leakage of water by reducing the number of connecting portions.
상기 목적을 달성하기 위한 본 발명의 가스보일러의 플로우스위치 및 자동보충수밸브의 열교환기연결구조는 난방배관에 물을 보충하는 자동보충수밸브; 온수사용을 감지하는 플로우스위치; 그리고 직수공급관과 연결되는 유입구를 가지며 상기 자동보충수밸브가 설치되는 제1유출구를 갖고 또한 열교환기로 연결되는 제2유출구를 갖는 것으로서 상기 플로우스위치가 측부에 결합되는 제1사출캡을 포함하여서 된 것을 특징으로 한다.To achieve the above object, the present invention provides a heat exchanger connecting structure for a flow switch and an automatic replenishing water valve of a gas boiler, comprising: an automatic replenishing water valve for replenishing water to a heating pipe; A flow switch for sensing the use of hot water; And a first injection cap having an inlet connected to the direct water supply pipe and having a first outlet through which the automatic replenishing water valve is installed and a second outlet connected to the heat exchanger, .

또한 본 발명은 상기 제1사출캡(20)을 열교환기(9)에 결합하기 위하여 아답타역할을 하는 제2사출캡(30)도 포함하고 있다. 제2사출캡(30)의 일측면은 열교환기(9)에 결합할수 있는 형상으로 되어 있고 다른 측면은 상기 제1사출캡(20)의 제2유출구(23)가 결합할수 있는 형상으로 되어 있다.The present invention also includes a second injection cap 30 serving as an adapter for coupling the first injection cap 20 to the heat exchanger 9. One side of the second injection cap 30 is shaped to be engageable with the heat exchanger 9 and the other side is shaped to allow the second outlet 23 of the first injection cap 20 to engage .

At this time, And generates an electrical signal corresponding thereto. Since such a flow switch is well known in the art, a detailed description thereof will be omitted.
자동보충수밸브(12)는 여러 형태의 것이 사용될수 있는데, 예를 들어 전기에 의해서 개폐작용을 하는 솔레노이드밸브가 이용될수 있다.The automatic replenishing water supply valve 12 may be of various types, for example, a solenoid valve which is opened and closed by electricity may be used.
상기와 같이 구성된 본 발명의 가스보일러의 플로우스위치 및 자동보충수밸브의 열교환기연결구조는 다음과 같이 작용한다.The connection structure of the heat exchanger of the flow switch and the automatic replenishing water valve of the gas boiler according to the present invention constructed as above operates as follows.
온수사용시 온수공급관(14)을 통하여 온수가 유출되면 직수공급관(13)에 직수가 흐르게 되는데 이때 직수는 제1사출캡(20)의 유입구(21)로 유입되어 제2유출구(23)를 통하여 열교환기(9)로 들어간다. 차가운 직수는 열교환기(9)내에서 난방수와의 열교환작용에 의해서 가열되어 온수로 변한후 온수공급관(14)을 통하여 유출한다. 그리고 직수가 제1사출캡(20)을 통과하기 때문에 플로우스위치(15)가 동작하여 온수사용사실을 제어장치에 입력한다.The hot water flows into the inlet port 21 of the first injection cap 20 and flows through the second outlet port 23 to the heat exchanging port 13 through the hot water supply pipe 14, (9). The cold direct water is heated in the heat exchanger 9 by heat exchange with the heating water and turned into hot water, and then flows out through the hot water supply pipe 14. Since the direct water passes through the first injection cap 20, the flow switch 15 operates to input the fact that the hot water is used to the control device.
또한 물탱크(7)의 플로트스위치(7a)의 동작에 의해서 난방배관에 물이 일정수준이하로 부족하게 되면 자동보충수밸브(12)가 자동으로 개방하여 직수가 제1사출캡(20)의 제1유출구(22), 자동보충수밸브(12), 물보충관(11)을 거쳐서 물탱크(7)로 들어가 난방배관에 물을 보충하게 된다.When the float switch 7a of the water tank 7 is operated and water is insufficient in the heating pipe to a certain level or less, the automatic replenishing water valve 12 is automatically opened so that the direct water is discharged from the first injection cap 20 The water flows into the water tank 7 through the first outlet 22, the automatic replenishing water valve 12 and the water replenishing pipe 11 to replenish water to the heating pipe.
상기와 같은 본 발명의 플로우스위치 및 자동보충수밸브의 열교환기연결구조는 플로우스위치(15)와 자동보충수밸브(12)가 한군데 집중하여 설치되어 있고 또한 열교환기에 직접 연결되어 있기 때문에 가스보일러의 조립라인에서 조립작업이 매우 간편하게 되고, 배관구조가 단순하게 되는 효과를 발휘한다. 따라서 조립시간이 적게 소요되고 제조단가가 저렴하게 된다.Since the flow switch 15 and the automatic replenishing water valve 12 are concentrically installed in one heat exchanger and the heat exchanger is connected directly to the heat exchanger, The assembling work in the assembly line becomes very simple, and the piping structure is simplified. Therefore, the assembly time is short and the manufacturing cost is low.
또한 본 발명은 배관연결개소를 줄여서 그 만큼 물의 누설의 가능성과 누설로 인한 불량발생의 가능성을 적게 하는 효과를 발휘한다.In addition, the present invention has the effect of reducing the number of piping connection points, thereby reducing the possibility of water leakage and the possibility of occurrence of defects due to leakage.
