Description
본 고안은 가스보일러에 관한 것으로서, 더욱 상세하게는 난방 및 온수겸용 가스보일러에서 난방동작 및 온수동작시 각각의 난방유로가 다르게 설정되어질 수 있도록 함으로서 보일러의 효율을 개선시키기 위한 난방환수관 구조에 관한 것이다.The present invention relates to a gas boiler, and more particularly, to a heating return pipe structure for improving the efficiency of a boiler by allowing each heating passage to be set differently during heating operation and hot water operation in a gas boiler for both heating and hot water. will be.
일반적으로, 난방 및 온수겸용 가스보일러는 가스를 연료로 하여 주열교환기내를 순환하는 물을 가열하므로서 이의 가열되는 물을 난방배관으로 순환시켜 난방출력을 얻도록 함과 아울러 별도로 구비되는 온수 열교환기 측으로도 순환시켜 온수출력을 선택적으로 얻도록 하는 것이다.In general, a gas boiler for heating and hot water is used to heat water circulating in a main heat exchanger 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 is to circulate also to obtain hot water output selectively.
즉, 주열교환기에서 가열되는 물을 온수순환회로를 통해 난방사용시와 온수사용시로 구분하여 선택적으로 열교환이 이루어질 수 있도록 함으로서 난방 및 온수사용을 겸할 수 있도록 하는 것이다.In other words, the water heated in the main heat exchanger is divided into heating and hot water through a hot water circulation circuit so that heat can be selectively exchanged to serve both heating and hot water.
이러한 난방 및 온수겸용 가스보일러의 온수순환회로는 여러가지 방식이 제안되어 사용되고 있는데, 도 1은 종래 가스보일러의 난방순환수 배관구조를 나타낸 개략도이다.The hot water circulation circuit of the gas boiler for heating and hot water combined use is proposed and used, Figure 1 is a schematic diagram showing a heating circulation water piping structure of a conventional gas boiler.
즉, 도시된 바와같이 가스보일러의 난방배관에 물을 보충하게 되면, 난방배관에 차있던 공기는 난방수환수관(1)을 통하여 물탱크(3)로 배출되고, 순환펌프(P)의 구동에 의해 펌핑력이 가해지는 난방배관(4)내의 난방수는 환수되어 버너(5)에 의해 가열되는 열교환기(6)를 통과하는 과정에서 열교환된 후, 온수열교환기(8)가 분기되어지는 삼방변(2)의 안내를 받아 난방수공급관(7)을 통하여 난방배관(4)으로순환된다.That is, when water is supplemented to the heating pipe of the gas boiler as shown, the air filled in the heating pipe is discharged to the water tank (3) through the heating water return pipe (1), the driving of the circulation pump (P) The heating water in the heating pipe 4 to which the pumping force is applied is exchanged in the process of passing through the heat exchanger 6 heated by the burner 5, and then the hot water heat exchanger 8 is branched. Guided by the side (2) is circulated to the heating pipe (4) through the heating water supply pipe (7).
그러나, 상기와 같은 종래의 가스보일러는 설치후 난방배관(4)내에 남아있는 공기를 제거하는 에어퍼지(Air-Purge) 동작을 위해 난방수 유로가 보일러내에 설치되어져 있는 물탱크(3)를 경유하도록 함으로서 온수출탕시간이 지연되어지는 불편이 있었다.However, the conventional gas boiler as described above passes through the water tank 3 in which the heating water flow path is installed in the boiler for an air purge operation for removing the air remaining in the heating pipe 4 after installation. By doing so, there was a inconvenience that the hot water tapping time is delayed.
한편, 개방형 가스온수보일러의 경우에는 온수출탕속도를 상승시키기 위하여 난방수의 순환시 물탱크를 경유하지 않도록 하는 방식을 채택하는데, 이러한 경우에는 에어퍼지 시간이 과다하게 소요되어 가동중 난방배관에서의 비등음(물 끓는 소리)이 발생되는 문제점이 있었다.On the other hand, in the case of open gas hot water boiler, in order to increase the hot water tapping speed, a method is adopted so as not to go through the water tank during circulation of the heating water. In this case, the air purge time is excessively consumed. There was a problem that the boiling sound (boiling water) of the.
본 고안은 상기한 종래 문제점을 개선하기 위해 제안된 것으로서, 난방작동시와 온수작동시에 난방수의 유로를 각기 달리 설정토록 함으로서 온수출탕시간 및 에어퍼지 시간을 모두 단축시킬 수 있도록 하는 난방환수관 구조를 제공하는데 목적이 있다.The present invention is proposed to improve the above-mentioned conventional problems, heating return to reduce both hot water tapping time and air purge time by setting the flow path of the heating water differently during heating operation and hot water operation. The purpose is to provide a tubular structure.

The heating return pipe includes an inner pipe forming a plurality of flow paths. The dual-pipe structure consists of an external appearance, and the heat exchanged water is recovered from the outlet and hot water heat exchanger, which supplies water to be heated to the main heat exchanger during operation of the circulation pump applying the circulation force to the flow path. The recovery port can be achieved through the heating and return pipe structure of the combined hot water and heating gas boiler, characterized in that each branch is formed in appearance.
이하, 본 고안의 구체적인 실시예를 첨부도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
먼저, 본 실시예에 따른 난방환수관(10)의 구조를 살펴보면 도 4 및 도 5에 도시된 바와같이, 중앙에서 제1유로(11a)를 이루게 되는 내관(11)과 내관(11)을 감싸는 형태의 제2유로(12a)를 이루는 외관(12)이 일체로 사출성형되어진 2중관 구조를 이루게 된다.First, referring to the structure of the heating return pipe 10 according to the present embodiment, as shown in FIGS. 4 and 5, the inner tube 11 and the inner tube 11 forming the first flow passage 11a at the center thereof are enclosed. The exterior 12 constituting the second flow passage 12a of the form forms a double tube structure that is integrally injection molded.
특히, 난방환수관(10)의 외관(12)면에는 순환펌프(P)에 의한 펌핑동작시 가열이 이루어지게될 순환수를 주 열교환기(6)측으로 공급하게 되는 출수구(13)와, 온수열교환기(8)로 부터 열교환이 이루어진 순환수가 회수되어지는 회수구(14)가 내부에서 연통되어진 상태로 높이를 달리하며 소정 높이로 돌출 형성되어지게 된다.In particular, the exterior 12 surface of the heating return pipe 10 has a water outlet 13 for supplying circulating water to be heated to the main heat exchanger 6 during the pumping operation by the circulation pump (P), and hot water The recovery port 14 through which heat-exchanged circulating water is recovered from the heat exchanger 8 is formed to protrude to a predetermined height while varying in height while being in communication with the inside.
도 2 및 도 3은 상기 난방환수관(10)이 설치되어진 가스보일러의 개략적인 내부구성 및 유로흐름 상태를 나타낸 것으로서, 보일러의 내부구성을 이루고 있는 기타 요소에 대해서는 도 1을 통해 설명되었던 종래기술에서와 동일한 도면부호를 부여하였다.2 and 3 illustrate a schematic internal configuration and a flow path state of the gas boiler in which the heating return pipe 10 is installed, and the other elements constituting the internal configuration of the boiler have been described with reference to FIG. 1. The same reference numerals are used as in.
이와같은 구성을 이루고 있는 가스보일러의 동작에 따른 작용효과를 살펴보기로 한다.The working effect of the operation of the gas boiler constituting such a configuration will be described.
먼저, 실내 난방을 위한 초기 난방운전이 실시되어질 경우에는 도 2에 도시된 바와같이 삼방변(2)의 개폐작동에 의해 온수열교환기(8)측의 온수배관은 차단되어짐과 동시에 난방배관(4)측으로의 배관유로는 개방되어지게 된다.First, when the initial heating operation for the indoor heating is carried out as shown in Figure 2 by the opening and closing operation of the three-way (2) the hot water pipe on the hot water heat exchanger 8 side is blocked and at the same time heating pipe (4) The piping flow path to the side is opened.
이러한 상태에서 순환펌프(P)가 작동되어짐에 의해 펌핑되어지는 순환수는 난방배관(4)을 따라 이송되어지는 가운데 실내난방을 이루게 되고, 난방작용을 수행한 난방수는 난방환수관(10)을 따라 물탱크(3)로 환수되어 순환수에 함유되어있는 공기에 대한 에어퍼지가 이루어지게 된다. 이때, 난방환수관(10)을 통한 환수는 내관(11)이 이루고 있는 제1유로(11a)를 통해 안내되어지게 된다.In this state, the circulating water pumped by the circulating pump P is operated to form room heating while being transported along the heating pipe 4, and the heating water that performs the heating operation is the heating return pipe 10. It is returned to the water tank (3) along the air purge for the air contained in the circulating water is made. At this time, the return through the heating return pipe 10 is guided through the first passage (11a) that the inner tube (11).
그리고, 이와같이 환수된 순환수는 계속적으로 작용되는 순환펌프(P)의 순환력에 의해 난방환수관(10)의 외관(12)이 형성하고 있는 제2유로(12a)를 따라 다시 유입되어진 후 출수구(13)를 통해 출수 되어지게 되고, 이후 주열교환기(6)를 통과하게 됨으로서 난방을 위한 높은 온도로의 열교환이 재차 이루어지는 반복적인 순환유로를 이루게 됨을 알 수 있다.The circulated water returned in this way is introduced again along the second flow path 12a formed by the outer surface 12 of the heating return pipe 10 by the circulation force of the circulating pump P which is continuously operated, and then the outlet port. It is to be withdrawn through the (13), and then pass through the main heat exchanger (6) it can be seen that the heat exchange to a high temperature for heating to form a repetitive circulation flow path again.
한편, 이와같이 실내난방이 이루어지고 있는 상태에서 사용자가 온수를 사용하기 위해 온수용 수도꼭지를 개방하게 되면, 도 3에 도시된 바와같이 삼방변(2)이 작동되어 난방배관(4)측의 유로는 차단됨과 동시에 온수열교환기(8)측의 온수배관이 개방되어지게 된다.On the other hand, when the user opens the hot water faucet in order to use the hot water while the room is being heated in this way, as shown in FIG. 3, the three-way valve 2 is operated so that the flow path of the heating pipe 4 side is At the same time, the hot water pipe on the hot water heat exchanger 8 side is opened.
이러한 상태에서 주열교환기(6)에서 높은 온도로 가열되어진 가열수가 순환펌프(P)의 순환력에 의해 온수열교환기(8)를 통과하게 됨으로서 온수열교환기(8)의 가온이 이루이지게 됨과 함께 높은 온도로 가온되어진 온수열교환기(8)를급수구(17)를 통해 공급되어진 급수가 통과하게 되면 열교환이 이루어지게 됨으로서 출탕구(18)를 통해 순간적인 온수출탕이 이루어지게 된다.In this state, the heated water heated to the high temperature in the main heat exchanger (6) passes through the hot water heat exchanger (8) by the circulation force of the circulation pump (P), so that the warming of the hot water heat exchanger (8) is achieved and high. When the water supplied through the water supply port 17 passes the hot water heat exchanger 8 heated to a temperature, heat exchange is performed, and thus instantaneous hot water tapping is performed through the hot water outlet 18.
그리고, 상기 온수열교환기(8)를 통과한 순환수는 난방환수관(10)의 회수구(14)를 통해 회수되어진 후 다시 주열교환기(6)로의 순환이 이루어지게 되는데, 이때 순환수는 상기 난방운전에서와 달리 물탱크(3)를 경유하지 않고, 제2유로(12a)상에서 다시 출수구(13)를 통해 주열교환기(8)로 공급되어지는 순환유로를 이루게 되는 것이다.Then, the circulating water passing through the hot water heat exchanger 8 is recovered through the recovery port 14 of the heating return pipe 10 and then circulated back to the main heat exchanger 6, wherein the circulating water is Unlike in the heating operation, the circulation passage is supplied to the main heat exchanger 8 through the outlet 13 again on the second passage 12a without passing through the water tank 3.
이와같이 온수출탕을 위한 가열수가 물탱크(3)를 경유하지 않게됨에따라 온수 출탕시간이 단축되어짐과 함께 순환수의 열손실을 최소화 할 수 있게됨을 알 수 있다.As such, as the heated water for hot water tapping does not pass through the water tank 3, it is understood that the hot water tapping time is shortened and heat loss of the circulating water can be minimized.
따라서, 본 고안의 난방환수관(10)이 설치되어진 상태에서 난방 및 온수운전이 실시되어지게 되면 난방작동시에는 에어퍼지시간이 단축되어지고, 온수작동시에는 온수출탕시간을 단축시킬 수 있는 이점을 나타내게 됨으로서 제품의 신뢰성 및 소비자 만족도를 향상시킬 수 있게되는 것이다.Therefore, if the heating and hot water operation is carried out in the state in which the heating return pipe 10 of the present invention is installed, the air purge time is shortened during the heating operation, and the hot water tapping time can be shortened during the hot water operation. By showing this advantage it is possible to improve the reliability and customer satisfaction of the product.
그리고, 상기에서 본 고안의 특정한 실시예가 설명 및 도시되었지만 본 고안의 난방환수관 구조가 당업자에 의해 다양하게 변형되어 실시될 가능성이 있는 것은 자명한 일이다.In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the heating and return pipe structure of the present invention may be variously modified and implemented by those skilled in the art.
그러나, 이와 같은 변형된 실시예들은 본 고안의 기술적 사상이나 전망으로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시예들은 본 고안의 첨부된 실용신안등록청구범위 안에 속한다 해야 할 것이다.However, such modified embodiments should not be individually understood from the technical spirit or prospect of the present invention, and such modified embodiments should fall within the attached utility model registration claims of the present invention.
이상에서 살펴본 바와같은 본 고안의 난방환수관 구조는, 2중관 형태의 난방환수관을 난방배관의 환수유로상에 설치토록 함으로서 난방작동시에만 순환수가 물탱크를 경유하여 순환되어지도록 함으로서 에어퍼지 시간 단축하고, 온수작동시에는 물탱크를 경유하지 않고 난방환수관 내에서 직접 환수가 이루어지는 내부 순환유로를 이루도록 함으로서 온수출탕시간을 단축시킬 수 있는 유용한 고안임을 알 수 있다.The heating return pipe structure of the present invention, as described above, installs a double-pipe heating return pipe on the return flow path of the heating pipe so that the circulation water is circulated through the water tank only during the heating operation to purge the air purge time. It can be seen that it is a useful design that can shorten the hot water tapping time by forming an internal circulation flow path where water is directly returned within the heating return pipe without passing through the water tank during hot water operation.
