이중관 구조의 이송로가 형성된 가스보일러용 물탱크{WATER RANK FOR GAS BOILER WHICH EQUIPPED WITH DUAL PIPE STRUCTURED TRANSPORT WAY}WATER RANK FOR GAS BOILER WHICH EQUIPPED WITH DUAL PIPE STRUCTURED TRANSPORT WAY}

본 고안은 이중관 구조의 이송로가 형성된 가스보일러용 물탱크에 관한 것으로서, 가스보일러의 물탱크 내부에 이중구조를 갖는 이송관을 형성하여 버너에 의해 가열되어 난방배관을 따라 순환되는 난방수의 순환시 외부노출에 의한 열손실 차단할 수 있도록 한 이중관 구조의 이송로가 형성된 가스보일러용 물탱크에 관한 것이다.The present invention relates to a water tank for a gas boiler in which a conveying path of a double pipe structure is formed, and forms a conveying pipe having a double structure in the water tank of the gas boiler, and is heated by a burner to circulate along the heating pipe. The present invention relates to a water tank for a gas boiler, in which a transfer pipe having a double pipe structure is formed to block heat loss caused by external exposure during the process.

일반적으로, 가스보일러는 가스를 연료로 이용하고 이를 연소시켜 연소과정에서 발생되는 열로 물을 가열하며 가열된 물을 순환펌프에 의해 난방배관으로 순환시켜 난방을 하거나 또는 온수를 공급하기 위한 장치를 말한다.In general, a gas boiler is a device that uses gas as a fuel and burns it to heat water with heat generated during the combustion process, and circulates the heated water through a circulation pump to a heating pipe for heating or to supply hot water. .

이러한, 가스보일러는 다양한 형태로 이미 널리 알려져 사용되고 있으며, 첨부 도면 도 1은 종래 가스보일러의 난방순환수 배관구조를 나타내는 개략도로서, 가스보일러의 난방배관에 물을 보충하게 되면, 난방배관에 차있던 에어는 난방수회수관(1)과 에어배출관(2)을 통하여 물탱크(3)로 배출되고 순환펌프(P)의 구동에 의해 난방배관(4)내의 난방수는 환수되어 버너(5)에 의해 가열되는 열교환기(6)에서 열교환된 후, 난방수공급관(7)을 통하여 난방배관(4)으로 순환되는 것을 나타내는 것이다.Such a gas boiler is already widely known and used in various forms. FIG. 1 is a schematic view showing a heating circulating water piping structure of a conventional gas boiler, and when water is replenished in a heating pipe of a gas boiler, the gas boiler is filled with a heating pipe. Air is discharged to the water tank (3) through the heating water recovery pipe (1) and the air discharge pipe (2), and the heating water in the heating pipe (4) is returned to the burner (5) by driving the circulation pump (P). After the heat exchange in the heat exchanger (6) to be heated by the heating water supply pipe (7) is shown to be circulated to the heating pipe (4).

이때, 난방수가 순환되면서 발생되는 에어나 열교환기(6)의 과열등으로 인해 발생된 에어는 에어배출관(2)을 통하여 물탱크(3)로 배출된다.At this time, the air generated by circulating the heating water or the overheating of the heat exchanger (6) is discharged to the water tank (3) through the air discharge pipe (2).

그러나, 상기와 같은 종래의 가스보일러에서는 난방 및 온수 공급을 위한 난방수의 순환시 열교환기에서 열교환이 이루어진 난방수가 통과되는 난방공급관이 외부에 노출된 상태이므로 외부(대기) 접촉에 의해 열손실이 발생하게 되어 열효율이 떨어지게 되고 또한, 난방배관을 거치면서 난방을 이룬 후, 난방수회수관을 통하여 물탱크내로 유입되어 열교환이 이루어지지 않은 상태로 물탱크에 저장된 난방수와 혼합되므로 열교환기를 통하여 얻은 열의 손실이 클 뿐만 아니라, 열교환기의 열교환을 통하여 얻게 된 열이 과다하게 손실된 상태로 순환펌프 구동에 의해 다시 순환되어 열교환기에서 재차 열교환이 이루어지게 되므로 열교환기에 의한 열교환시 많은 열량이 요구되어 많은 연소 및 열교환 시간과 연소에 따른 가스의 소모량이 증가하게 되는 등의 비효율적이고 경제적이지 못한 문제점이 발생하게 되었다.However, in the conventional gas boiler as described above, since the heating supply pipe through which the heating water is heat exchanged in the heat exchanger is exposed to the outside during circulation of the heating water for heating and hot water supply, heat loss is caused by external (atmosphere) contact. The heat efficiency decreases and heats through the heating pipe, and then enters the water tank through the heating water collection pipe and is mixed with the heating water stored in the water tank without heat exchange. In addition to the large heat loss, the heat gained from the heat exchanger is excessively lost and circulated again by the driving of the circulation pump, and the heat exchange is performed again in the heat exchanger. High combustion and heat exchange times and increased gas consumption due to combustion Inefficient and uneconomical problems have arisen.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 그 목적은 난방수를 가열·순환시켜 난방 및 온수를 공급함에 있어, 버너의 연소에 의해 열교환기로부터 열교환이 이루어진 난방수가 외부에 노출되지 않은 상태로 난방배관으로 공급되도록 하여 외부(대기) 접촉에 의한 열손실을 최소화 할 수 있으며 또한, 난방배관을 통하여 난방 및 온수 공급이 이루어진 후 재차 열교환을 위해 순환되어지는 난방수가 열교환이 이루어지지 않은 상태의 물탱크내에 저장된 난방수와 혼합되지 않고 바로 순환펌프를 통하여 열교환기로 공급되어 열교환이 이루어지도록 함에 따라, 버너의 연소효율을 높여 연소시 요구되는 가스량 및 열교환 시간을 최대한 절약 및 단축시킬 수 있도록 된 새로운 형태의 이중관 구조를 갖는 가스보일러의 물탱크를 제공하고자 하는 것이다.The present invention is to solve the conventional problems as described above, the purpose is to supply heating and hot water by heating and circulating the heating water, the heating water is heat exchanged from the heat exchanger by the burner is not exposed to the outside It is possible to minimize the heat loss caused by external (standby) contact by supplying it to the heating pipe without heating. Also, the heating water circulated for heat exchange after the heating and hot water supply through the heating pipe is not heat exchanged. As it is not mixed with the heating water stored in the water tank in the state, it is directly supplied to the heat exchanger through the circulation pump to perform heat exchange, thereby increasing the combustion efficiency of the burner so as to save and shorten the amount of gas required during combustion and heat exchange time as much as possible. Water tank of gas boiler with new double pipe structure I would like to.

이와 같은 목적을 달성하기 위하여, 본 고안은 버너의 연소에 의한 열교환기에서 열교환이 이루어진 난방수가 순환펌프에 의해 난방수공급관을 통하여 난방배관으로 공급된 후 난방수회수관을 통하여 일정량의 난방수가 저장된 물탱크로 순환·공급됨에 따라 난방 및 온수 공급이 이루어지는 가스보일러에 있어서, 상기 물탱크의 내부에 이중관 구조를 갖는 제 1, 2이송로가 형성된 특징을 갖는다.In order to achieve the above object, the present invention is the heating water is heat-exchanged in the heat exchanger by combustion of the burner is supplied to the heating pipe through the heating water supply pipe by the circulation pump and then a certain amount of heating water is stored through the heating water recovery pipe. A gas boiler in which heating and hot water supply is performed by being circulated and supplied to a water tank, wherein the first and second transfer paths having a double pipe structure are formed inside the water tank.

Is supplied to the heat exchange (12) is made and supplied to the heating pipe 14 through the heating water supply pipe 13, the heating water heat exchanged in the heat exchanger 12 is the first transport path formed in the water tank (15) The heating water supplied to the heating pipe 14 by the heating water supply pipe 13 through the heating pipe 20 and circulated along the heating pipe 14 is circulated through the heating recovery pipe 16. The heat exchange is performed again in the heat exchanger 12 by the drive.

이때, 난방배관(14)으로 순환된 난방수는 난방수회수관(16)을 통하여 물탱크(15)내에 형성된 제 2이송로(20')를 거쳐 순환펌프(P)의 구동에 의해 다시 열교환기(12)로 공급되어 열교환이 이루어지고, 상기 제 1, 2이송관(20, 20')은 외관(20a, 20a')과 내관(20b, 20b')으로 이루어지고 이들 사이에는 일정 공간의 단열공기층(20c, 20c')을 가진다.At this time, the heating water circulated to the heating pipe 14 is heat-exchanged again by driving the circulation pump P through the second transfer path 20 'formed in the water tank 15 through the heating water collecting pipe 16. It is supplied to the machine 12 and the heat exchange is performed, the first and second conveying pipe (20, 20 ') is composed of the exterior (20a, 20a') and the inner tube (20b, 20b ') between the predetermined space It has insulating air layer 20c, 20c '.

도 3은 본 고안에 따른 물탱크의 부분 확대 단면도로서, 일정량의 난방수가 저장되는 물탱크(15) 내부에 상면으로부터 하단에 이르도록 제 1이송로(20)가 관통되거나 또는 하단으로부터 일측방에 이르도록 제 2이송로(20')가 연통되되, 제 1, 2이송로(20, 20')는 소정간격 이격되어 일정 공간의 단열공기층(20c, 20c')을 갖는 내관(20a, 20a')과 외관(20b, 20b')으로 이루어진 것을 나타내는 것이다.3 is a partial enlarged cross-sectional view of the water tank according to the present invention, the first conveying path 20 is penetrated from the upper surface to the lower end inside the water tank 15 in which a predetermined amount of heating water is stored or is located at one side from the lower end. The second conveying path 20 'is in communication with each other, and the first and second conveying paths 20 and 20' are spaced apart by a predetermined interval, and the inner pipes 20a and 20a 'having the adiabatic air layers 20c and 20c' of a predetermined space. ) And appearance 20b, 20b '.

이때, 물탱크(15) 내부에 형성된 제 1이송로(20)는 열교환기(12)를 거친 난방수공급관(13)의 단부와 연통되도록 연결되고 제 2이송로(20')는 난방회수관(16)과 연통되도록 연결된다.At this time, the first transport path 20 formed in the water tank 15 is connected to communicate with the end of the heating water supply pipe 13 through the heat exchanger 12 and the second transport path 20 'is a heating recovery pipe It is connected to communicate with (16).

여기에서, 가스보일러에 사용되는 관(管)은 주로, 동(銅)으로 이루어지거나 합성수지 사출관으로 이루어지게 되는 것으로, 본 고안에서는 동관을 사용하는 가스보일러에 적용되기 보다는 합성수지 사출관을 사용하는 가스보일러에서의 사용이 적합한 것이다.Here, the pipe (pipe) used for the gas boiler is mainly made of copper or made of a synthetic resin injection pipe, in the present invention using a synthetic resin injection pipe rather than being applied to the gas boiler using copper pipe It is suitable for use in gas boilers.

이와 같은 본 고안의 사용상태를 설명하면 다음과 같다.Referring to the use state of the present invention as follows.

도 2 및 도 3에 도시된 바와 같이, 외관(20a, 20a')과 내관(20b, 20b')으로 이루어지고 이들 사이에 일정 공간의 단열공기층(20c, 20c')이 형성된 제 1, 2이송로(20, 20')가 형성된 물탱크(15)가 구비된 가스보일러를 이용하여 난방 및 온수를 공급하고자 할 경우에는 버너(11)를 연소시켜 열교환기(12)를 가열하게 되면, 난방수가 열교환기(12)를 거치면서 열교환이 이루어지게 되어 고온상태로 난방수공급관(13)을 통하여 난방배관(14)으로 순환·공급되면서 난방공급이 이루어지며, 난방배관(14)으로 순환되면서 난방공급을 이룬 난방수는 난방수회수관(16)을 통하여 다시 순환·공급되는 것으로서, 이때, 열교환기(12)에서 열교환이 이루어진 난방수는 물탱크(15) 내에 형성된 제 1이송로(20)를 거쳐 난방수공급관(13)을 통하여 난방배관(14)에 공급되므로 열교환이 이루어진 난방수가 난방수공급관(13)을 통하여 난방배관(14)에 공급됨에 있어 외부(대기)로의 노출이 차단된 상태이므로 외부 접촉에 따른 열손실을 방지할 수 있고 또한, 제 1이송로(20)를 통과함에 있어서는 내관(20a)과 외관(20b) 사이에 형성된 단열공기층(20c)에 의해 물탱크(15)내에 저장된 난방수(열교환이 이루어지지 않은 상태)와의 접촉이 차단되므로 열손실없이 열교환되어진 고온상태가 유지되는 것이다.As shown in FIGS. 2 and 3, the first and second transfers are made up of the exteriors 20a and 20a 'and the inner tubes 20b and 20b', and the insulating air layers 20c and 20c 'of a predetermined space are formed therebetween. In the case of supplying heating and hot water by using a gas boiler equipped with a water tank 15 having the furnaces 20 and 20 ', the burner 11 is burned to heat the heat exchanger 12. The heat exchange is performed while passing through the heat exchanger (12), and the heat is supplied while being circulated and supplied to the heating pipe (14) through the heating water supply pipe (13) at a high temperature, and the heat is supplied while being circulated to the heating pipe (14). The heating water which is formed is circulated and supplied again through the heating water collection pipe 16. At this time, the heating water that has undergone heat exchange in the heat exchanger 12 opens the first transfer path 20 formed in the water tank 15. Since the heat is supplied to the heating pipe 14 through the heating water supply pipe 13, Since water is supplied to the heating pipe 14 through the heating water supply pipe 13, the exposure to the outside (atmosphere) is blocked, and thus heat loss due to external contact can be prevented, and the first transport path 20 can be prevented. In passing, the contact with the heating water stored in the water tank 15 (without heat exchange) is blocked by the insulating air layer 20c formed between the inner tube 20a and the exterior 20b. The state is maintained.

이렇게 하여, 열교환된 고온상태로 난방수가 난방수공급관(13)을 통하여 난방배관(14)으로 순환·공급되어 난방이 이루어지게 되며, 일정한 주기(온도변화에 따라 설정된 주기)로 연속·반복되는 순환펌프(P)의 구동에 의해 난방수회수관(16)을 통하여 재차 열교환을 위한 순환이 이루어지게 된다.In this way, the heating water is circulated and supplied to the heating pipe 14 through the heating water supply pipe 13 in the heat exchanged high temperature state, and heating is performed, and the circulation is continuously and repeated at a constant cycle (cycle set according to the temperature change). By the driving of the pump P, the circulation for heat exchange is again performed through the heating water recovery pipe 16.

이때, 난방배관(14)을 거쳐 난방수회수관(16)으로 유입된 난방수는 위에서 언급된 열교환이 이루어진 난방수가 제 1이송로(20)를 거치는 과정에서 단열공기층(20c)에 의해 열손실이 방지됨과 마찬가지로 제 2이송로(20')에 의해 열손실[난방배관(14)을 순환하면서 난방 및 온수 공급을 행하면서 열교환기에서 열교환으로 얻은 고온상태는 아니지만, 열교환이 이루어지지 않은 상태로 물탱크(15)내에 저장된 난방수보다는 높은 온도를 갖고 있음] 방지된 상태로 순환펌프(P)에 의해 다시 열교환기(12)로 순환·공급되어 재차 열교환이 이루어지면서 연속·반복순환되는 것이다.At this time, the heating water introduced into the heating water recovery pipe 16 through the heating pipe 14 is the heat loss by the heat insulating air layer 20c in the course of the heating water made of the heat exchange mentioned above passes through the first transport path 20. As this is prevented, the heat loss (heating and hot water supply while circulating the heating pipe 14 by the second conveying path 20 'is not a high temperature state obtained by heat exchange in the heat exchanger, but without heat exchange. It has a higher temperature than the heating water stored in the water tank 15] is circulated and supplied to the heat exchanger 12 again by the circulation pump P in a prevented state, and is continuously and repeatedly circulated while performing heat exchange again.

따라서, 물탱크(15)내에 형성된 제 1, 2이송로(20, 20')에 의해 난방수가 순환·공급됨에 있어, 외부 접촉에 의한 열손실 및 열교환이 이루어지지 않은 상태로 물탱크(15)에 저장된 난방수와의 혼합에 따른 열손실을 막을 수 있는 것이다.Therefore, the heating water is circulated and supplied by the first and second transfer paths 20 and 20 'formed in the water tank 15, so that the water tank 15 is not in a state of heat loss and heat exchange due to external contact. The heat loss caused by mixing with the heating water stored in the can be prevented.

이와 같이, 난방수를 가열·순환시켜 난방 및 온수를 공급함에 있어, 버너의 연소에 의해 열교환기로부터 열교환이 이루어진 난방수가 외부에 노출되지 않은 상태로 난방배관으로 공급될 수 있도록 물탱크에 단열공기층을 갖는 이중관 구조의 제 1, 2이송로를 형성함에 따라, 난방수의 외부(대기) 접촉에 의한 열손실을 최소화 할 수 있고, 난방수의 재차 열교환시 열교환이 이루어지지 않은 상태로 물탱크내에 저장된 난방수와 혼합에 따른 열손실을 막을 수 있어 난방수의 열효율 및 버너의 연소효율을 높여 연소시 요구되는 가스량 및 열교환 시간을 최대한 절약 및 단축시킬 수 있어 효율적이고 경제적인 효과가 있다.In this way, in heating and circulating the heating water to supply heating and hot water, an insulating air layer is provided in the water tank so that the heating water, which has undergone heat exchange from the heat exchanger by the burner combustion, can be supplied to the heating pipe without being exposed to the outside. By forming the first and second conveyance paths having a double pipe structure having a structure, heat loss due to external (atmosphere) contact of the heating water can be minimized, and heat exchange is not performed in the water tank during the heat exchange of the heating water again. Heat loss due to mixing with the stored heating water can be prevented, thereby increasing the thermal efficiency of the heating water and the combustion efficiency of the burner, thereby saving and reducing the amount of gas and the heat exchange time required for combustion as efficiently and economically as possible.
