Relates to a hot water boiler.
일반적으로, 가정에서 필요로 하는 목용용 온수와 난방용 온수는 보일러(boiler)를 통해서 공급받게 되는데, 이러한 종래의 가정용 온수 보일러를 살펴보면, 도 2 에서 보는 바와 같이, 점선으로 도시된 일정형상의 케이스에 내설되어 보일러의 열원으로 작용되는 버너(101), 이 버너(101)의 상부에 위치되며 냉수를 온수로 변환시키도록 파이프의 외면에 긴 날개가 형성된 모양의 핀튜브(Fin Tube)로 이루어진 주열교환기(102), 이 주열교환기(102)를 경유해서 연장된 난방용파이프(107)의 일단을 감싸도록 된 개방식팽창탱크(103), 상기 난방용파이프(107)가 하부로 연장되면서 순환펌프(104)를 사이에 두고 연결되어 유입되는 물의 흐름방향을 바꾸도록 된 3방향밸브(105), 이 3방향밸브(105)에서 연장된 난방용파이프(107)가 연결되는 판형열교환기(106), 이 판형열교환기(106)와 연결되며 유량감지센서(111)가 부착된 냉/온수파이프(108,108') 및 보일러 전체의 전기적 신호를 제어하도록 된 제어판(109)과 상기 버너(101)에 연료를 공급하도록 된 연료공급파이프(110)로 구성된다.In general, the hot water for the wood and the hot water for heating required in the home are supplied through a boiler. Looking at the conventional domestic hot water boiler, as shown in FIG. Burner 101, which is installed internally and serves as a heat source of the boiler, is located at the top of the burner 101, and a main heat exchanger made of a fin tube having a long wing formed on the outer surface of the pipe to convert cold water into hot water. (102), an open expansion tank (103) configured to surround one end of the heating pipe (107) extending through the main heat exchanger (102), and the heating pipe (107) extends to the lower portion of the circulation pump (104). A three-way valve 105 connected between the three-way valve 105 to change the flow direction of the incoming water, a plate heat exchanger 106 to which the heating pipe 107 extending from the three-way valve 105 is connected, and the plate heat exchanger (10 6) and a fuel supply adapted to supply fuel to the burner 101 and the control panel 109 to control the electrical signals of the entire boiler and the cold / hot water pipes 108 and 108 'with the flow rate sensor 111 attached thereto. It consists of a pipe (110).
이에 따라 사용자가 실내의 난방을 위해 실내에 설치된 난방용 스위치를 누르게 되면, 제어판(109)으로 보내진 신호에 의해 상기 3방향밸브(105)의 온수쪽 방향이 폐쇄되는 한편 난방쪽 방향은 개방되고, 상기 순환펌프(104)가 작동됨과 동시에 상기 버너(101)가 작동되어 연료공급파이프(110)에서 공급되는 연료가 연소되면서 열이 발생되고, 이 열이 상기 주열교환기(102)를 통해 상기 난방용파이프(107) 내부로 흐르는 물을 가열하게 되며, 이 가열된 물이 상기 3방향밸브(105)를 통해 난방공급파이프(107a)쪽으로 출수(↓방향)되어 실내를 순환하여 난방환수파이프(107b)를 통해 환수(↑방향)되는 한편, 과팽창된 온수는 상기 개방식팽창탱크(103)에 저장되게 된다.Accordingly, when the user presses a heating switch installed in the room for heating the room, the hot water side of the three-way valve 105 is closed while the heating side is opened by the signal sent to the control panel 109. At the same time the circulation pump 104 is operated, the burner 101 is operated to generate heat as the fuel supplied from the fuel supply pipe 110 is burned, and the heat is generated through the main heat exchanger 102. 107) to heat the water flowing inside, the heated water is discharged to the heating supply pipe (107a) through the three-way valve 105 (↓ direction) to circulate the room through the heating return pipe (107b) While returning (↑ direction), the over-expanded hot water is to be stored in the open expansion tank (103).
반면, 사용자가 온수를 사용하기 위해 수도꼭지를 틀게되면 상기 냉수파이프(108)에 설치된 유량감지센서(111)에 의해 냉수의 유입이 감지되고, 이 유량감지센서(111)의 신호가 제어판(109)에 전달되며, 이 제어판(109)의 신호에 의해 상기 3방향밸브(105)의 난방쪽 방향이 폐쇄되는 한편 온수쪽 방향은 개방되고, 상기 순환펌프(104)와 버너(101)가 작동되어 전술된 난방과정과 동일과정을 거쳐 가열된 물이 이번에는 상기 3방향밸브(105)를 통해 판형열교환기(106)를 통과하게 되는데, 이때 상기 냉수파이프(108)의 급수방향(↑방향)에서 유입되는 냉수가 상기 판형열교환기(106)를 거치게 되면서 온수로 변환되어 온수파이프(108')를 통해 출수(↓방향)되게 된다.On the other hand, when the user turns on the faucet to use hot water, the inflow of cold water is detected by the flow sensor 111 installed in the cold water pipe 108, the signal of the flow sensor 111 is the control panel 109 The heating direction of the three-way valve 105 is closed while the hot water side is opened, and the circulation pump 104 and the burner 101 are operated by the signal of the control panel 109. The water heated through the same process as the heating process is passed through the plate heat exchanger 106 through the three-way valve 105, in which case the inflow in the water supply direction (↑ direction) of the cold water pipe 108 As the cold water is passed through the plate heat exchanger 106 is converted into hot water is discharged through the hot water pipe 108 '(↓ direction).
그러나 종래의 온수 보일러는 보일러 가동시에 냉수(14℃ 내외)가 온수(65℃ 이상)로 변환되는 과정에서, 보일러의 주열교환기 쪽으로 유입되어 핀튜브 내부로흐르는 물의 온도(14℃ 내외)가 낮아 순간적으로 높은 버너열(600℃)과 맞닿으면서 주열교환기의 핀튜브에 결로수가 발생되고, 이 결로수가 탄산가스, 황산가스 및 질소산화물과 같은 배기가스와 결합되면서 주열교환기의 핀튜브에 흰가루가 발생되는 백화현상이 일어나는 문제점이 있었을 뿐만 아니라, 이러한 백화현상으로 인해 보일러를 1년 정도 사용하게 되면 주열교환기의 열교환 능력이 현저하게 저하되어 동일한 열량을 얻기 위해서 더 많은 연료를 소비해야 되므로 연료비가 상승되는 문제점도 있었다.However, the conventional hot water boiler has a low temperature (about 14 ° C) of the water flowing into the main heat exchanger of the boiler and flowing into the fin tube while the cold water (about 14 ° C) is converted into hot water (65 ° C or more) when the boiler is operated. Condensation water is generated in the fin tube of the main heat exchanger instantaneously with high burner heat (600 ° C), and the condensation water is combined with the exhaust gases such as carbon dioxide, sulfuric acid gas and nitrogen oxide, and white powder is applied to the fin tube of the main heat exchanger. In addition, there was a problem of the occurrence of bleaching. In addition, when the boiler is used for about a year, the heat exchange capacity of the main heat exchanger is significantly reduced, and fuel costs are increased because more fuel must be consumed to obtain the same amount of heat. There was also a problem.
종래에는 이러한 문제점을 해결하고자 비례제어기술을 이용하여 주열교환기로 유입되는 냉수의 온도를 40℃ 이상 높여서 결로수 발생을 감소시키는 기술이 적용된 바 있으나, 이 역시 목욕 등에 필요한 온수를 출탕할 때에는 14℃의 냉수가 주열교환기로 직접 유입되므로 핀튜브 결로에 의한 백화현상을 근본적으로 차단할 수 없는 문제점이 있었다.Conventionally, in order to solve this problem, a technique of reducing condensation water by increasing the temperature of the cold water flowing into the main heat exchanger by 40 ° C. or more using a proportional control technique has been applied. Since cold water is directly introduced into the main heat exchanger, there was a problem in that it cannot fundamentally block the whitening phenomenon caused by the condensation of the fin tube.
한편, 상기 주열교환기(102)의 핀튜브에 14℃의 냉수가 직접 공급되는 것을 방지하기 위해서 보일러의 본체 외부에 별도로 온수저장탱크가 설치된 보일러를 살펴보면, 도 3 에서 보는 바와 같이(도 2와 동일부위에는 동일부호를 표기하고 동일한 구조에 대한 설명은 생략함), 보일러의 외부에 대용량의 온수저장탱크(112)가 설치되고, 이 온수저장탱크(112)내에 가열파이프(113)가 내설되어, 이 가열파이프(113)를 통해 공급되는 온수에 의해 온수저장탱크(112)내의 물이 가열되고, 이 가열된 물이 온수저장탱크(112)의 일측에 연결된 온수공급파이프(114)들을 통해 목용용 온수로써 공급되는 한편, 실내난방을 위해서는 3방향밸브(105)와 분배기(115)를 사이에 두고 연결된 난방공급파이프(107a)들을 통해 난방수가 실내로 유입된 후, 난방환수파이프(107b)를 통해 환수되도록 구성되어 있다.On the other hand, in order to prevent the cold water of 14 ℃ directly supplied to the fin tube of the main heat exchanger (102) Looking at the boiler separately installed in the hot water storage tank outside, as shown in Figure 3 (the same as Figure 2 The same parts are marked with the same reference numerals and description of the same structure is omitted), and a large-capacity hot water storage tank 112 is installed outside the boiler, and a heating pipe 113 is installed in the hot water storage tank 112. Water in the hot water storage tank 112 is heated by the hot water supplied through the heating pipe 113, the heated water for the wood through the hot water supply pipe 114 connected to one side of the hot water storage tank 112 While supplied as hot water, the heating water flows into the room through the heating supply pipes 107a connected with the three-way valve 105 and the distributor 115 therebetween for indoor heating, and then through the heating return pipe 107b. Returned It is configured to.
즉, 14℃의 냉수가 온수저장탱크(112)내부로 직접 공급되어 목욕이나 샤워용 온수로 사용하도록 온수 사용만을 위한 전용탱크가 보일러 본체 외부에 별도 설치된 구조로 이루어져 있었다.That is, 14 ℃ of the cold water was supplied directly into the hot water storage tank 112, a dedicated tank for using only hot water to be used as a hot water for bath or shower was made of a separate structure outside the boiler body.
이는 온수를 대량으로 사용하기 위한 것으로 설치장소와 대형 온수저장탱크설치로 복잡한 배관시설과 비용 등에 문제점이 있었다.This is to use a large amount of hot water, there was a problem in the installation and the installation of large hot water storage tank complex pipe facilities and costs.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 일정온도 이상으로 가열된 온수가 저장되는 축열탱크가 보일러 케이스 내부에 내설되고, 이 축열탱크 내부에 온수열교환파이프가 설치되며, 이 온수열교환파이프를 통해 상기 축열탱크에 미리 저장된 온수를 이용하여 난방 및 목욕용 온수로 사용될 수 있도록 함으로써, 보일러의 순간온수능력을 향상시키는 한편, 판형열교환기를 배제하고 구성부품을 간단히 하여 온수온도의 변화를 줄임과 함께 주열교환기의 결로 및 백화현상을 방지하여 보일러의 내구수명을 향상시키고, 보일러 내부의 복잡한 배관을 줄임으로써 고장요인 제거 및 제조원가를 절감하도록 된 벽걸이형 가정용 온수 보일러를 제공하는데 그 목적이 있다.The present invention has been invented to solve the above problems, the heat storage tank is stored in the boiler case is stored in the hot water heated to a predetermined temperature or more, the heat storage heat exchange pipe is installed in the heat storage tank, the hot water Through the heat exchange pipe, the hot water stored in the heat storage tank can be used as hot water for heating and bathing, thereby improving the instantaneous hot water capacity of the boiler, excluding the plate heat exchanger, and simplifying the components to reduce the change in hot water temperature. In addition, the purpose of the present invention is to provide a wall-mounted domestic hot water boiler which prevents condensation and whitening of the main heat exchanger to improve the durability of the boiler and to reduce the trouble factor and reduce the manufacturing cost by reducing the complicated piping inside the boiler.

또한 상기 축열탱크(1)내에는 저장된 물의 온도를 감지하도록 된 온도감지센서(10)가 설치된다.In addition, the heat storage tank 1 is provided with a temperature sensor 10 to detect the temperature of the stored water.
그리고 상기 제1순환펌프(4)는 직/교류 전원을 사용하여 그 속도를 가변시킬 수 있는 모터가 내장되어 제어판(13)과 전기적으로 연결된다.In addition, the first circulation pump 4 has a built-in motor capable of varying its speed using a direct / AC power supply and is electrically connected to the control panel 13.
이에 따라, 사용자가 실내의 난방을 위해 실내에 설치된 난방용 스위치를 누르게 되면, 제어판(13)으로 보내진 신호에 의해 상기 제2순환펌프(7)가 작동되어 상기 축열탱크(1)내에 저장된 온수가 난방공급파이프(5)를 통해 출수(↓방향)되어 실내로 공급되는 한편, 상기 제어판(13)에서 또 다른 신호가 발생되어 상기 제1순환펌프(4)가 작동되어 축열탱크(1)내의 온수가 난방수가열파이프(3)를 통해 공급되고, 상기 버너(11)가 작동됨에 따라 연료공급파이프(14)에서 공급되는 연료가 연소되면서 열이 발생되어 상기 주열교환기(12)를 통해 난방수가열파이프(3) 내부로 흐르는 물을 가열하게 되며, 이 가열된 물이 축열탱크(1)쪽으로 연장된 난방수가열파이프(3)를 경유하여 상기 축열탱크(1) 내부로 저장됨과 동시에 상기 난방공급파이프(5)를 통해 출수되어 실내를 경유하여 상기 난방환수파이프(6)를 통해 환수(↑방향)된다.Accordingly, when the user presses a heating switch installed in the room for heating the room, the second circulation pump 7 is operated by a signal sent to the control panel 13 so that the hot water stored in the heat storage tank 1 is heated. While the water is discharged through the supply pipe 5 (↓ direction) and supplied to the room, another signal is generated from the control panel 13 to operate the first circulation pump 4 so that the hot water in the heat storage tank 1 As the heating water is supplied through the heating pipe 3 and the burner 11 is operated, the fuel supplied from the fuel supply pipe 14 is burned to generate heat, and thus the heating water heating pipe is heated through the main heat exchanger 12. (3) Heat the water flowing inside, and the heated water is stored in the heat storage tank (1) via the heating water heating pipe (3) extending toward the heat storage tank (1) and at the same time the heating supply pipe (5) is discharged through the interior The oil is water exchange (↑ direction) through the heat-exchange pipes (6).
즉, 상기 난방공급파이프(5)를 통해 실내로 유입되는 최초의 난방수는 축열탱크(1)에 이미 저장된 온수가 직접 공급되고 이후에는 버너(11) 및 주열교환기(12)를 통해 가열된 물이 축열탱크(1)를 거쳐 난방공급파이프(5)로 연속적으로 공급 및 난방환수파이프(6)를 통해 환수되므로, 보일러의 순간온수능력을 향상시킬 수 있을 뿐만 아니라 항상 일정온도의 온수가 난방수로 공급될 수 있게 된다.That is, the first heating water introduced into the room through the heating supply pipe 5 is directly supplied with hot water already stored in the heat storage tank 1, and then the water heated by the burner 11 and the main heat exchanger 12. Through this heat storage tank (1) and continuously supplied to the heating supply pipe (5) and returned through the heating return pipe (6), not only can improve the instantaneous hot water capacity of the boiler, but also hot water at a constant temperature always Can be supplied.
한편, 사용자가 목욕 등의 생활온수를 사용하기 위해 수도꼭지를 틀게되면 일차적으로 상기 온수열교환파이프(2)내의 자체 관수(40℃ 이상)가 온수출수구(2b)를 통해 나가게 되는 한편, 상기 냉수급수구(2a)를 통해 냉수가 들어오면, 상기 온도감지센서(10)에 의해 축열탱크(1)내의 수온 저하가 감지되어 제어판(13)으로 신호가 보내져서 이 신호에 의해 상기 제1순환펌프(4)가 작동됨과 함께 버너(11)가 가열되어, 상기 난방수가열파이프(3)내로 흐르는 물을 가열시키고, 이 가열된 물이 다시 축열탱크(1)내로 입수되면서 상기 온수열교환파이프(2)내의 물이 가열되는 과정을 되풀이 하게 된다. 즉, 상기 축열탱크(1)내의 온수에 의해 상기 온수열교환파이프(2)내의 물이 간접 가열된다.On the other hand, when the user turns on the faucet to use the hot water, such as a bath, the first self-watering (40 ° C or more) in the hot water heat exchange pipe (2) is discharged through the hot water outlet (2b), while the cold water inlet When cold water comes in through (2a), the water temperature drop in the heat storage tank (1) is detected by the temperature sensor (10) and a signal is sent to the control panel (13) by the signal to the first circulation pump (4) ) And the burner 11 is heated to heat the water flowing in the heating water heating pipe 3, and the heated water is supplied back into the heat storage tank 1, and thus, in the hot water heat exchange pipe 2. The process of heating the water is repeated. That is, the water in the hot water heat exchange pipe 2 is indirectly heated by the hot water in the heat storage tank 1.
즉, 본 발명에 따르면 상기 축열탱크(1)내에 저장된 온수에 의하여 난방 및 목욕용 온수가 공급되도록 된다.That is, according to the present invention is to be supplied hot water for heating and bath by the hot water stored in the heat storage tank (1).
그리고 상기 축열탱크(1)내에 저장된 물의 온도가 변화되면 상기 온도감지센서(10)에 의해 제어판(13)으로 신호가 보내지면서 상기 제1순환펌프(4)가 작동되어, 상기 주열교환기(12)와 축열탱크(1)사이에 온수가 순환되어 축열탱크(1)내의 물의 온도를 조절할 수 있게 되는데, 이때 상기 제1순환펌프(4)내의 모터는 가변식으로 작동하여 수온의 설정온도에 비해 현저히 낮을 경우에는 회전속도가 빠르게 이루어지고, 설정온도에 근접될 경우에는 그 회전속도를 줄이도록 되어, 제1순환펌프(4)의 소비전력을 낮출 수 있게 되는 한편, 축열탱크(1)내에 저장되는 물의 온도를 항상 일정하게 유지할 수 있게 된다.When the temperature of the water stored in the heat storage tank 1 is changed, a signal is sent to the control panel 13 by the temperature sensor 10 and the first circulation pump 4 is operated to operate the main heat exchanger 12. And hot water is circulated between the heat storage tank 1 and the temperature of the water in the heat storage tank 1 can be adjusted. At this time, the motor in the first circulation pump 4 operates variably to significantly compare with the set temperature of the water temperature. When it is low, the rotational speed is made faster, and when it approaches the set temperature, the rotational speed is reduced, so that the power consumption of the first circulation pump 4 can be lowered, while being stored in the heat storage tank 1. The water temperature can be kept constant at all times.
그리고 상기 난방수가열파이프(3)를 통해 얻어진 온수 중 과팽창된 온수는 상기 팽창탱크(8)의 배출파이프(8a)를 통해 외부로 배출될 수 있게 된다.And the hot water over-expanded in the hot water obtained through the heating water heating pipe (3) can be discharged to the outside through the discharge pipe (8a) of the expansion tank (8).
그러므로 상기 난방수가열파이프(3)를 통해 주열교환기(12)로 공급되는 물은 항상 상기 축열탱크(1)에 저장되어 있던 온수가 공급되므로, 낮은 온도의 냉수가 주열교환기(12)의 핀튜브를 지날 때 발생되는 결로로 인한 백화현상이 방지되어 주열교환기(12)의 성능저하를 방지하게 된다.Therefore, the water supplied to the main heat exchanger 12 through the heating water heating pipe 3 is always supplied with hot water stored in the heat storage tank 1, so that cold water of low temperature is supplied to the fin tube of the main heat exchanger 12. The whitening phenomenon due to the condensation generated when passing through is prevented to prevent the deterioration of the main heat exchanger 12.
한편, 본 발명의 요지를 벗어나지 않는 범위 내에서 상기 축열탱크(1)의 위치 및 크기를 다양하게 변경하여 보일러의 전체 형상을 변경할 수 있음은 물론이다.On the other hand, it is a matter of course that the overall shape of the boiler can be changed by variously changing the position and size of the heat storage tank (1) within the scope not departing from the gist of the present invention.
이상 설명한 바와 같이 본 발명에 따르면, 난방과 목욕용 온수를 주열교환기로부터 저장하도록 된 축열탱크가 보일러 케이스 내부에 일체형으로 설치되고 내장된 축열탱크내에 목욕용 온수 공급시, 14℃ 냉수가 주열교환기에 직접 유입되어 결로 및 백화현상을 초래하는 것을 방지하여 보일러의 수명과 효율저하를 방지하고, 종래의 보일러에 사용되는 판형열교환기와 3방향밸브를 배제시켜 부품수를 줄이고 이 부분에서 발생되는 누수현상 등 잦은 고장을 방지하며 원가를 절감할 수 있는효과가 있다.As described above, according to the present invention, a heat storage tank configured to store heating and hot water for the bath from the main heat exchanger is integrally installed in the boiler case, and 14 ° C. cold water flows directly into the main heat exchanger when hot water for bath is supplied into the built-in heat storage tank. This prevents condensation and whitening, and prevents the boiler's lifespan and efficiency from dropping, and eliminates the plate heat exchanger and three-way valve used in conventional boilers, reducing the number of parts and causing frequent breakdowns such as water leakage. To reduce costs and reduce costs.
또한, 종래의 복잡한 배관을 줄여 축열탱크상에 간단히 설치하여 고장과 누수의 원인을 제거시키는 한편, 축열탱크로부터 미리 가열된 온수를 사용함으로써 보일러 가동시간이 상대적으로 단축되어 연료비를 절감시킬 수 있으며, 축열탱크와 주열교환기 사이에 설치된 제1순환모터에 의해 목욕용 온수 사용시 온수열교환파이프의 외벽으로 온수를 순환시킴으로써 난류가 형성되어 정체된 상태에서 온수 열교환되는 것보다 열교환 능력이 향상되는 효과가 있다.In addition, by reducing the conventional complicated piping simply installed on the heat storage tank to eliminate the cause of failure and leakage, while using the pre-heated hot water from the heat storage tank, the boiler operating time is relatively shortened to reduce fuel costs, By using the first circulation motor installed between the heat storage tank and the main heat exchanger, when the hot water for bath is used, the hot water is circulated to the outer wall of the hot water heat exchange pipe, thereby improving the heat exchange capacity than the hot water heat exchange in the stagnant state.
