본 고안은 난방 및 온수겸용 가스보일러의 온수순환회로에 관한 것으로, 특히, 난방방식시에도 온수열교환기를 가열시켜 순산적인 온수출탕을 얻을 수 있도록 한 것이다.The present invention relates to a hot water circulation circuit of a gas boiler combined with heating and hot water, and in particular, it is possible to obtain a pure hot water hot water by heating the hot water heat exchanger even in the heating method.

일반적으로, 난방 및 온수겸용 가스보일러는 가스를 연료로하여 주열교환기내를 순환하는 물을 가열하므로서 이의 가열되는 물을 난방배관으로 순환시켜 난방출력을 얻도록 함과 아울러 별도로 구비되는 온수열교환기 측으로도 순환시켜 온수출력을 선택적으로 얻도록 하는 것이었다.In general, both a heating and hot water gas boiler heats water circulating in the main heat exchanger by using gas as a fuel to circulate the heated water to a heating pipe to obtain a heating output and to provide a separate hot water heat exchanger. It was to circulate also to obtain hot water output selectively.

즉, 주열교환기에서 가열되는 물을 온수순환회로를 통해 난방사용시와 온수사용시로 구분하여 선택적으로 행하므로서 난방 및 온수사용을 겸할 수 있도록 하는 것이었다.In other words, the water heated in the main heat exchanger was selectively divided into heating and hot water through a hot water circulation circuit so as to serve both heating and hot water.

이러한 난방 및 온수겸용 가스보일러의 온수순환회로는 이미 여러가지 방식이 제안되어 사용되고 있었으며, 일예를 들어 종래의 온수순환회로의 구성을 살펴보면, 이는 제1도 및 제2도에서 보는 바와같이 가스보일러의 가스버너에 의해 가열되는 주열교환기(1)의 입수부에는 난방배관을 순환한 난방수가 환수되는 난방환수관(2)이 연결되어 있음과 동시에 이의 난방환수관(2)에는 배관내의 물을 강제 순환시키는 순환펌프(3)가 구비되어 있고, 또한, 주열교환기(1)의 출수부와 연결되는 배관의 소정위치에는 주열교환기(1)로부터 공급되는 온수를 두방향으로 선택하여 순환시키는 삼방향밸브(4)가 구비되어 있다.The hot water circulation circuit of the gas boiler for heating and hot water combined has already been proposed and used. For example, the configuration of the conventional hot water circulation circuit is as follows, as shown in FIGS. 1 and 2. The inlet of the main heat exchanger (1) heated by the burner is connected to the heating return pipe (2) for returning the heating water circulated through the heating pipe, and the heating return pipe (2) forcibly circulating the water in the pipe. Three-way valve (4) is provided, and the three-way valve (4) for selecting and circulating the hot water supplied from the main heat exchanger (1) in two directions at a predetermined position of the pipe connected to the water outlet of the main heat exchanger (1). ) Is provided.

상기 삼방향밸브(4)의 일측배관은 난방배관으로 온수를 공급하는 난방공급관(5)과 연결되어 있음과 아울러 타측배관은 온수열교환기(6)와 연결되어 있으며, 또한, 상기 온수열교환기(6)에는 별도의 온수배관(7)이 구비되어 온수만을 사용시 온수열교환기(6)에 의해 물이 가열되도록 되어있는 구성이었다.One side pipe of the three-way valve (4) is connected to the heating supply pipe (5) for supplying hot water to the heating pipe and the other pipe is connected to the hot water heat exchanger (6), the hot water heat exchanger ( 6) was provided with a separate hot water pipe (7) so that the water is heated by the hot water heat exchanger (6) when only hot water is used.

따라서 난방으로만 사용시에는 제1a도에서 보는 바와같이 삼방향밸브(4)의 개폐작동에 의해, 즉 온수열교환기(6)측의 온수배관은 차단함과 동시에 난방공급관(5)의 온수배관은 개방하므로서, 순환펌프(3)에 의해 펌핑되는 순환수는 난방배관으로 부터 난방환수관(2)을 통해 환수되어 주열교관기(1)를 거치는 동안 높은온도로 가열된후 삼방향밸브(4)를 거쳐 난방공급관(5)을 통해 난방배관으로 순환되어지는 것을 연속반복하므로서 난방을 이루게 되는 것이었고, 또한, 온수를 사용시에는 제1b도에서 보는 바와같이 삼방향밸브(4)가 난방공급관(5)의 온수배관은 차단함과 동시에 온수열교환기(6)의 온수배관은 개방하므로서 주열교환기(1)에서 가열된 순환수는 삼방향밸브(4)를 통해 온수열교환기(6)측으로 순환되는 것을 반복하게 되는 것이고, 이때 온수열교환기(6)를 통과하는 가열된 물이 온수배관(7)내의 물을 가열하게 되므로서 온수를 얻는 구성이었다.Therefore, when only heating is used, as shown in FIG. 1A, by opening and closing the three-way valve 4, that is, the hot water pipe on the hot water heat exchanger 6 side is blocked and the hot water pipe of the heating supply pipe 5 is By opening, the circulating water pumped by the circulation pump (3) is returned from the heating pipe through the heating return pipe (2) and heated to a high temperature while passing through the main heat pipe (1), and then the three-way valve (4). Through the heating supply pipe (5) through the circulating to the heating pipe is repeated to achieve the heating, and when using hot water, as shown in Figure 1b three-way valve (4) is the heating supply pipe (5) The hot water pipe of) is blocked and at the same time the hot water pipe of the hot water heat exchanger 6 is opened while the circulating water heated in the main heat exchanger 1 is circulated to the hot water heat exchanger 6 through the three-way valve 4. Will be repeated, at this time Group 6, the heated water flowing through the hot water to obtain a configuration was standing so that heat water in the hot water pipe 7.

그러나, 이와같은 종래의 구성은 제1도에서도 보는 바와같이 난방사용시 주열교환기(1)에서 가열된 물이 삼방향밸브(4)를 통하여 직접 난방배관으로 순환됨과 아울러, 온수사용시에는 삼방향밸브(4)에 의해서 이의 가열된 물이 온수열교환기(6)를 간접 가열하는 구성임에 따라 사용자가 온수를 사용하기 위해 온수수도꼭지를 열었을때 온수열교환기(6)내에 남아있는 찬물이 미쳐 가열되지 못하여 온수열교환기(6)를 가열하는 시간까지 상당량의 찬물이 배수되어지는 문제점이 야기되었던 것이었다.However, this conventional configuration, as shown in Figure 1, the water heated in the main heat exchanger (1) in the heating use is circulated directly to the heating pipe through the three-way valve (4), and in the case of hot water three-way valve ( 4) The heated water indirectly heats the hot water heat exchanger 6, so when the user opens the hot water faucet to use hot water, the cold water remaining in the hot water heat exchanger 6 cannot be heated. The problem was that a considerable amount of cold water was drained by the time of heating the hot water heat exchanger 6.

즉, 난방사용시에는 온수열교환기내의 난방수 및 온수배관내의 물은 가열되지 않는 상태가 되어 급탕이 이루어지지 않으므로서 많은량의 물을 버리게되는 문제점이 있는 것이었다.In other words, when the heating is used, the heating water in the hot water heat exchanger and the water in the hot water pipe are not heated so that the hot water is not made and a large amount of water is discarded.

따라서, 본 고안은 상기와 같은 사정을 고려하여 이루어진 것으로, 그 목적은 급탕이 이루어지도록하여 온수 사용시 물의 낭비를 줄이도록 하는 난방 및 온수겸용 가스보일러의 온수순환회로를 제공함에 있다.Accordingly, the present invention has been made in consideration of the above circumstances, and an object thereof is to provide a hot water circulation circuit of a gas boiler for heating and hot water combined with a hot water supply to reduce waste of water when using hot water.

이러한 목적은 난방시에도 온수열교환기를 가열하도록 하므로서 달성되는 것인데, 즉, 삼방향밸브를 온수열교환기의 다음단계에 구비하여 난방사용시도 주열교환기에서 가열되는 물이 온수열교환기를 순환하면서 온수열교환기를 가열토록 하므로서 순간적인 온수출탕을 얻도록 하는 것이 특징인 것이다.This object is achieved by heating the hot water heat exchanger even during heating, i.e., by providing a three-way valve in the next step of the hot water heat exchanger, the water heated in the main heat exchanger circulates in the hot water heat exchanger when the heating is used, thereby heating the hot water heat exchanger. By doing so, it is characterized by getting instant hot water tap.

계속해서, 본 고안의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Subsequently, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도면의 제2도는 본 고안에 관한 가스보일러의 온수순환회로를 보인 구성도로서, 이는 가스보일러의 본체내에 구비되고, 난방환수관(2) 및 난방공급관(5)으로서 미도시된 난방배관과 연결되는 난방방식과 또한, 상기 난방 방식에 의해 가열되고 수도관과 연결되어 급수됨과 아울러 온수꼭지와 연결되어 온수를 배출시키는 온수방식을 동시에 갖추어 구성된다.2 is a configuration diagram showing the hot water circulation circuit of the gas boiler according to the present invention, which is provided in the main body of the gas boiler and is connected to a heating pipe not shown as a heating return pipe 2 and a heating supply pipe 5. In addition, the heating method is heated and heated by the heating method is connected to the water pipe, and is also equipped with a hot water system connected to the hot water faucet to discharge hot water at the same time.

즉, 순환펌프(3)에 의해 순환되는 물을 주열교환기(1)로 통과시켜 높은 온도로 가열되게한 후, 이의 가열수로 온수열교환기(6)를 가열토록 함과 동시에 난방배관으로 순환시켜 난방을 이루도록 하고, 또한, 상기 온수열교환기(6)에서 가열되는 물을 배출시켜 온수를 얻도록 하는 것이다.That is, the water circulated by the circulation pump (3) is passed through the main heat exchanger (1) to be heated to a high temperature, and then the hot water heat exchanger (6) with the heating water to circulate in the heating pipe at the same time. To achieve heating, and to discharge the water heated in the hot water heat exchanger (6) to obtain hot water.

이는 종래와 동일한 구성을 가지며, 다만 본 고안에서는 이러한 두개의 방식을 선택적으로 제어하는 삼방향밸브(4)를 온수열교환기(6)의 다음단계에 구비하고, 또한, 상기 삼방향밸브(4)와 연결되는 일측배관에는 난방환수관(2)과 연결되는 순환관(8)을 구비함과 아울러 타측배관에는 난방배관과 연결되는 난방공급관(5)을 구비하므로서 난방사용시에도 주열교환기(1)에서 가열되는 물이 온수열교환기(6)로 순환되도록 한 것이다.It has the same configuration as in the prior art, but in the present invention, the three-way valve (4) for selectively controlling these two methods is provided in the next step of the hot water heat exchanger (6), and the three-way valve (4) The one side pipe connected to the heating pipe has a circulation pipe (8) connected to the heating return pipe (2) and the other pipe is provided with a heating supply pipe (5) connected to the heating pipe in the main heat exchanger (1) during heating use The heated water is to be circulated to the hot water heat exchanger (6).

따라서, 이와같이 구성되는 본 고안의 난방사용시에는 콘트롤부의 제어에 의해 제2a도에서 보는 바와같이 삼방향밸브(4)의 순환관(8)측은 폐쇄됨과 동시에 난방공급관(5)측은 개방되므로서, 배관내의 물이 순환펌프(3)의 펌핑력으로 주열교환기(1)를 거쳐 가열된후 온수열교환기(6)를 통해 난방배관(7)으로 순환되어져 난방이 이루어지는 것이며, 이때, 주열교환기(1)에서 가열되는 물은 순환되면서 온수열교환기(6)내의 온수배관(7)도 가열하게 되는 것이다.Accordingly, in the heating use of the present invention configured as described above, the circulation pipe 8 side of the three-way valve 4 is closed and the heating supply pipe 5 side is opened, as shown in FIG. The water inside is heated through the main heat exchanger (1) by the pumping force of the circulation pump (3) and then circulated through the hot water heat exchanger (6) to the heating pipe (7), whereby the main heat exchanger (1) The water heated in is circulated while also heating the hot water pipe 7 in the hot water heat exchanger 6.

이와같이 난방이 이루어지는 상태에서 사용자가 온수를 사용하기 위해 온수용 선택버튼을 누름과 아울러 온수용 수도꼭지를 개방하게 되면, 제2b도에서 보는 바와같이 삼방향밸브(4)가 작동되어 순환관(8)측은 개방함과 동시에 난방공급관(5)측은 폐쇄하므로서 순환펌프(3)에 의해 순환되는 물은 주열교환기(1)에서 가열된후 온수열교환기(6)와 순환관(8)을 거쳐 다시 주열교환기(1)로 순환되어지는 것이고, 이에따라 온수배관(7)내에 이미 가열되어 있는 온수는 온수용 수도꼭지를 통해 배출되어지는 것이다.When the user presses the hot water selection button to use hot water in the heating state as well as the hot water faucet, the three-way valve 4 is operated as shown in FIG. While the side is opened and the heating supply pipe 5 is closed, the water circulated by the circulation pump 3 is heated in the main heat exchanger 1, and then again through the hot water heat exchanger 6 and the circulation pipe 8 and then the main heat exchanger. The hot water that is already circulated in (1) and thus already heated in the hot water pipe 7 is discharged through the hot water faucet.

이때, 온수용 수도꼭지를 통해 배출되어지는 온수배관(7)내의 온수는 배출되는 량만큼 수도로부터 급수가 되어지면서 주열교환기(1)로부터 순환되어지는 높은온도의 가열수에 의해 온수열교환기(6)내에서 가열되므로서 지속적으로 온수를 얻을수가 있게되는 것이다.At this time, the hot water in the hot water pipe (7) discharged through the hot water faucet is supplied from the tap water by the amount of discharged hot water heat exchanger (6) by the high temperature heating water circulated from the main heat exchanger (1) It will be able to get hot water continuously while being heated inside.

그러므로, 이와같이된 본 고안은 난방사용시에도 온수열교환기를 지속적으로 가열하므로서 사용자가 온수용 수도꼭지를 개방하기만 하면 그 즉시 온수가 배출되는, 즉, 순간적인 온수출탕효과를 가지게 되는 것이므로 물의 낭비를 줄일수가 있게되는 것이다.Therefore, the present invention is designed to reduce the waste of water because the hot water heat exchanger is continuously heated even when using the heating, so that the hot water is immediately discharged, that is, instantaneous hot water tapping effect. It will be possible.
