열매체유를 이용한 전기보일러{Electric boiler using thermal oil}Electric boiler using thermal oil
본 발명은 열매체유를 이용한 전기보일러에 관한 것으로, 더욱 상세하게는 비열이 높은 액상의 열매체유를 저장시킨 보일러 본체의 내부에 히터를 내설시킨 수관을 지그재그로 다층 배열하여 유입구로 급수된 물이 수관에 오랫동안 머물게하면서 전기히터와 가열되어 축열된 열매체유에 의거 효과적으로 가열되게 함으로서 난방을 신속하고 효율적으로 할 수 있게 한 열매체유를 이용한 전기보일러에 관한 것이다.The present invention relates to an electric boiler using a heat medium oil, and more particularly, a water pipe in which water supplied to an inlet is zigzag in a multi-layered water pipe in which a heater is built in a boiler body in which a high heat medium liquid heat oil is stored. The present invention relates to an electric boiler using heat medium oil, which enables heating to be quickly and efficiently by allowing an electric heater to be heated for a long time and effectively heating the heat oil stored therein.
일반적으로 전기보일러는 전기의 발열을 연료로 이용하여 축열조에 저장 순환되는 보일러수를 전열로서 직접 또는 간접으로 가열시키므로서 축열조의 가열된 보일러수가 급수배관 및 난방배관으로 공급 및 순환되면서 온수로써 이용되거나 실내난방을 할 수 있게 한 것으로 가스나 기름보일러에 비해 구조가 간단하고 위생적이며 과열등의 사고 위험도 상대적으로 적고 고효율인 장점은 있어 널리 사용되고 있다. 또한 근래에는 비열이 매우 높은 열매체유를 이용하여 비교적 전기소비량이 적은 심야전기로서 가열시키고 이 열매체유에 저장된 열량을 이용하여 다음날 난방하는 방식의 보일러도 개발되어 나오고 있다.In general, the electric boiler heats the boiler water stored in the heat storage tank directly or indirectly as a heat transfer by using the heat of electricity as fuel, so that the heated boiler water in the heat storage tank is used as hot water while being supplied and circulated to the water supply pipe and the heating pipe. As it enables indoor heating, it is widely used because of its simple structure, hygienic, relatively low risk of accidents such as overheating and high efficiency compared to gas or oil boilers. In recent years, a boiler has been developed in which a heat medium oil having a high specific heat is used as a late night electricity having a relatively low electricity consumption, and the next day is heated using the heat stored in the heat medium oil.
그러나 전기히터로서 직접 보일러수를 가열하는 전자의 구조는 전력소모가 매우 크고 후자의 축열된 열매체유를 이용하는 전기한 전기보일러는 열매체유의 열교환기에 코일상으로 형성한 수관을 설치하여 열매체유의 열교환으로 온수를 얻는 구조이므로 전기히터로서 직접 가열하는 것에 비해 전력소모는 적은 반면에 가열효과가 비교적 낮고 특히 냉수가 코일상의 수관으로 신속히 토출되어 가열시간이 적으므로 고효율의 열량을 얻을 수 없는 폐단이 있었다.However, the electric structure of heating the boiler water directly as an electric heater has a very high power consumption, and the electric electric boiler which uses the heat storage oil of the latter is installed in the heat exchanger of the heat medium oil by installing a water pipe formed in a coil shape. Because of the structure, the power consumption is lower than the direct heating as an electric heater, while the heating effect is relatively low. Especially, since the cold water is quickly discharged into the water pipe on the coil, the heating time is short.
본 발명은 이와같은 종래의 폐단을 해소하는 데 있는 것으로, 본 발명의 목적은 비열이 매우 높은 열매체유를 저장시킨 보일러 본체의 내부에 전기히터를 설치한 수관을 지그재그로 다층 설치하여 하부의 유입구로 유입된 냉수가 지그재그로 배열된 수관을 매우 오랫동안 머물면서 거쳐 상부의 유출구로 나가는 동안 전기히터와 축열된 열매체유와의 열교환으로 집중 가열되어 신속하게 난방 및 온수를 제공할 수 있도록 한 열매체유를 이용한 전기보일러가 제공하는 데 있다.The present invention is to solve such a conventional closed end, the object of the present invention is to install a multi-layered water pipe with a zigzag electric heater inside the boiler body in which the heat medium oil is stored very high specific heat to the lower inlet Using heat medium oil to provide heating and hot water quickly by intensive heating by heat exchange between electric heater and heat storage oil during the flow of cold water flowing through the zigzag water pipe for a very long time and going to the outlet of the upper part. The electric boiler is to provide.

In addition, the inside of the boiler main body 100 is attached with a temperature sensor 5 for detecting to maintain a constant temperature of the heat medium oil (1).
도 3은 보일러 본체(100)의 내부에 설치된 수관(300)의 배열상태를 간략하여 도시한 개략도이다.3 is a schematic diagram schematically showing the arrangement of the water pipe 300 installed inside the boiler body 100.
도면중 미설명 부호 6은 전선이다.Reference numeral 6 in the drawings is an electric wire.
이와같이 된 본 발명은 먼저 보일러 본체(100)의 열매체유(1)를 내저부에 설치된 전열수단(200)으로서 제어부의 타이머(미도시)에 의해 설정한 일정온도가 유지되게 가열시키게 되는 데, 실용화 단계에서는 전기비용이 비교적 싼 심야시간대에 온도감지센서(5)에 의해 자동으로 작동되어 일정한 온도가 유지되도록 하게 되면 가열된 열매체유(1)는 축열상태가 되어 이의 내부에 설치된 수관(300)을 가열시키게 된다. 이와 동시에 수관(300)의 내부에 설치된 전기히터(400)를 작동시키게 되면 수관(400)의 내부을 흐르는 보일러수는 전기히터(400)의 발열로서 가열됨과 동시에 축열상태에 있는 열매체유(1)에 의해서도 동시에 가열되므로 보일러수는 신속하게 가열되어 난방과 온수로서 사용할 수 있게 되는 데, 여기서 보일러 본체(100)의 내부에 설치된 수관(300)은 지그재그로 흐르도록 연통설치되고 또 수직연결관(4)에 의해 상하로 연통되게 다층으로 설치되어 있으므로 하부의 유입구(3)를 통해 유입된 보일러수는 수관(300)을 따라 지그재그로 보일러 본체(100)의 내부를 왕복하면서 하부에서 상승하여 상부로 이송되고 다시 지그재그로 왕복하면서 이송되다가 최상부에 형성된 토출구(2)를 통해 토출됨에 따라 유입구로 유입된 보일러수는 수관(300)을 지그재그로 통과하는 과정에서 오랬동안 관체의 내부에 머물게 되면서 충분히 가열되어 토출되므로서 매우 빠른 시간에 가열되어 난방과 급탕효율을 상승시키게 되는 것이다.In the present invention, the heating medium oil 1 of the boiler main body 100 is first heated to maintain a constant temperature set by a timer (not shown) of the control unit as the heat transfer means 200 installed at the inner bottom. In the step, when the electric cost is relatively low, it is automatically operated by the temperature sensor 5 during the late-night time period so that a constant temperature is maintained. The heated heat medium oil 1 becomes a heat storage state, and the water pipe 300 installed therein Heated. At the same time, when the electric heater 400 installed in the water pipe 300 is operated, the boiler water flowing inside the water pipe 400 is heated by the heat generated by the electric heater 400 and at the same time in the heat medium oil 1 in the heat storage state. Since the boiler water is heated at the same time to be heated quickly and can be used as heating and hot water, where the water pipe 300 installed inside the boiler body 100 is installed in communication to flow in a zigzag and the vertical connection pipe (4) Since it is installed in a multi-layer to communicate up and down by the boiler water introduced through the inlet 3 of the lower rises from the bottom while reciprocating the inside of the boiler body 100 in a zigzag along the water pipe 300 is transferred to the top and As it is transported while zigzag again and discharged through the discharge port 2 formed at the top, the boiler water introduced into the inlet passes through the water pipe 300 in a zigzag manner. Staying inside the tube for a long time in the well is heated and discharged enough to be heated very quickly to increase the heating and hot water efficiency.
이와같이 된 본 발명은 보일러수를 지그재그로 다층 배열 설치되어 축열되는 열매체유(1)로서 가열된 수관(300)의 내부를 순환시키고 동시에 전기히터(400)의 발열로서 가열시키게 되므로 가열효과가 매우 크고 난방과 급탕을 신속하게 공급할 수 있으며 빠른 시간에 가열하므로 전력소모를 대폭 줄일 수 있는 등 그 효과가 매우 크다.In the present invention, the boiler water is zigzag and is arranged in a multi-layered arrangement so as to circulate the inside of the water pipe 300 heated as the heat medium oil 1 to be regenerated, and at the same time, it is heated as the heat generated by the electric heater 400, and thus the heating effect is very large. The heating and hot water supply can be supplied quickly, and the heating can be done quickly, which greatly reduces the power consumption.
