전기보일러{electricity boiler}Electric boiler

본 발명은 전기보일러에 관한 것으로서, 보다 상세하게는 저렴한 심야전기를 이용하여 효율적으로 난방을 할 수 있을 뿐 아니라, 전기보일러의 사이즈를 줄일 수 있으며, 열처리시 사용되는 염욕용 솔트나 열처리용 오일 등을 활용하여 환경오염을 줄일 수 있도록 된 새로운 구성의 전기보일러에 관한 것이다.The present invention relates to an electric boiler, and more particularly, it is possible not only to efficiently heat using an inexpensive midnight electric power, but also to reduce the size of the electric boiler, salt for salt bath, heat treatment oil, etc. used during heat treatment. The present invention relates to an electric boiler with a new configuration that can reduce environmental pollution by using a.

일반적으로, 전기를 사용하여 난방를 하거나 온수를 가열하는 전기보일러는 물을 저장할 수 있도록 된 대용량의 저장탱크와, 저장탱크 내부의 물을 가열할 수 있도록 된 전기히터가 구비된 것으로, 전기요금이 싼 심야에, 전기히터를 이용하여 물을 가열한 후, 가열된 물의 열을 이용하여 낮시간 동안 난방을 하거나, 온수를 사용할 수 있도록 구성된다. 즉, 전기료가 싼 심야전력을 이용하여 열을 발생시킨 후, 이 열을 저장하여 낮시간 동안 난방에 사용하는 것이다.In general, electric boilers that use electricity to heat or heat hot water are equipped with a large-capacity storage tank capable of storing water and an electric heater that can heat water inside the storage tank. At night, the water is heated using an electric heater, and then heated during the daytime using the heat of the heated water, or configured to use hot water. In other words, heat is generated by using low-cost electric power at low cost, and the heat is stored and used for heating during the daytime.

그런데, 이러한 전기보일러는 비등점과 비열이 낮은 물을 이용하여 열을 저장하므로, 많은 양의 열을 저장하기 위해서는 전기보일러의 저장탱크가 매우 커야 되며, 따라서, 전기보일러 자체의 사이즈가 매우 커지므로, 설치공간이 작은 일반 가정에서는 사용하기 어려운 문제점이 있었다.However, since the electric boiler stores heat using water having a low boiling point and low specific heat, the storage tank of the electric boiler must be very large in order to store a large amount of heat, and thus, the size of the electric boiler itself becomes very large. There is a problem that is difficult to use in a typical home with a small installation space.

한편, 최근들어, 금속의 열처리 기술이 발전되어 감에 따라, 금속의 열처리에 사용되는 열처리용 오일이나 염욕용 솔트의 사용이 크게 늘어가고 있다. 이러한 열처리용 오일이나 염욕용 솔트는 매우 높은 온도에도 성질이 변하지 않을 뿐 아니라, 비등점과 비열이 매우 높은 특징이 있는데, 여러번 열처리에 사용된 후에는 이물질에 오염이 되어 폐기하여야 한다.On the other hand, in recent years, as the heat treatment technology of metals is developed, the use of heat treatment oils and salt bath salts used for heat treatment of metals has been greatly increased. The heat treatment oil or salt bath salt does not change its properties even at very high temperatures, and has a very high boiling point and specific heat. After several times of heat treatment, it is contaminated with foreign matter and must be disposed of.

그런데, 이러한 열처리용 오일이나 염욕용 솔트는 환경을 오염시키므로, 폐기처리하는 데 많은 비용이 드는 문제점이 있었다. 이러한 문제점은 전술한 열처리용 오일이나 염욕용 솔트 이외에 자동차용 엔진오일에도 동일하게 발생되었다.By the way, since the heat treatment oil or salt salt contaminates the environment, there is a problem in that a high cost for disposal. This problem is similarly generated in the engine oil for automobiles in addition to the above-described heat treatment oil or salt bath salt.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 저렴한 심야전기를 이용하여 효율적으로 난방을 할 수 있을 뿐 아니라, 전기보일러의 사이즈를 줄일 수 있으며, 열처리시 사용되는 염욕용 솔트나 열처리용 오일 등을 활용하여 환경오염을 줄일 수 있도록 된 새로운 구성의 전기보일러를 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention is to not only efficiently heating by using a low-cost midnight electricity, but also to reduce the size of the electric boiler, salt salt or It is to provide an electric boiler with a new configuration that can reduce environmental pollution by using heat treatment oil.

The first heat exchanger 12 is connected to the water supply pipe 10 and a hot water pipe 18 connected to a faucet for discharging hot water to transfer hot water, and the water supplied through the water supply pipe 10 is inside. After circulating the heated by the heat of the heat medium (2), and discharged through the hot water pipe (18), in the middle of the hot water pipe (18), a separate hot water mounted inside the outer tank (6) The tank 20 is further provided and configured to store heated hot water while passing through the first heat exchanger 12. Both ends of the second heat exchanger 14 extend into the outer tank 6 so that the water stored in the outer tank 6 can be circulated to be heated by the heat medium 2. , The water heated through the second heat exchanger 14 is circulated along the heating pipe 22 connected to the outer tank 6 to be heated. At this time, according to the amount of hot water used, it is also possible to further provide a separate hot water storage tank on the outside of the outer tank 6, so that a large amount of hot water can be stored.

상기 급수파이프(10)는 상기 제1 열교환기(12)에 연결되어 제1 열교환기(12)에 물을 공급하는 것 이외에, 그 중간부에 상기 외부탱크(6)로 개방되는 별도의 밸브(24)가 더 구비되어, 외부탱크(6)에 물을 공급하도록 구성된다. 이때, 상기 밸브(24)에는 외부탱크(6) 내부의 수위를 제어하는 플로터(26)가 장착되어, 외부탱크(6) 내부의 수위가 낮아지면, 자동으로 상기 밸브(24)가 개방되어 외부탱크(6)에 물을 공급하도록 구성된다.The water supply pipe 10 is connected to the first heat exchanger 12 to supply water to the first heat exchanger 12, and a separate valve that is opened to the outer tank 6 at an intermediate portion thereof ( 24 is further provided, and is configured to supply water to the outer tank (6). At this time, the valve 24 is equipped with a plotter 26 for controlling the water level inside the outer tank 6, when the water level inside the outer tank 6 is lowered, the valve 24 is automatically opened to the outside It is configured to supply water to the tank 6.

따라서, 전기료가 싼 심야시간에 상기 히터(4)를 이용하여 내부탱크(8)의 열매체(2)를 가열하고, 낮시간에는 상기 열교환기를 이용하여 물을 가열하므로써, 물을 덮혀 온수를 사용하거나, 난방을 할 수 있다. 이때, 가정용의 경우, 열매체(2)로 사용되는 오일이나 솔트는 대략 200℃정도로 가열하는 것이 바람직하고, 산업용의 경우, 300~400℃정도로 가열하는 것이 바람직하다.Therefore, by heating the heat medium 2 of the inner tank 8 using the heater 4 during the late night time when the electric charges are cheap, and by heating the water using the heat exchanger during the day time, the hot water is used to cover the water or , Can do heating. At this time, in the case of household use, it is preferable to heat the oil and salt used as the heat medium 2 to about 200 degreeC, and in industrial use, it is preferable to heat to about 300-400 degreeC.

이와같이 구성된 전기보일러는 비열과 비등점이 낮은 물을 이용하는 종래의 전기보일러와 달리, 비등점과 비열이 매우 높은 오일이나 솔트를 열매체(2)로 이용하여 열을 저장하므로, 열매체(2)를 저장하는 내부탱크(8)의 사이즈를 매우 작게 줄일 수 있으며, 따라서, 전기보일러 전체의 사이즈를 줄일 수 있으며, 설치공간이 작은 일반가정에서도 손쉽게 설치할 수 있는 장점이 있다.Unlike conventional electric boilers which use water having a low specific heat and boiling point, the electric boiler configured as described above uses oil or salt having a very high boiling point and specific heat as the heat medium 2 to store heat, thereby storing the heat medium 2. It is possible to reduce the size of the tank 8 very small, and thus, to reduce the size of the entire electric boiler, there is an advantage that can be easily installed in a general home with a small installation space.

또한, 상기 전기보일러는 산업폐기물인 폐오일이나 폐솔트를 열매체(2)로 이용할 수 있으므로, 산업폐기물을 처리하는 데 소요되는 비용을 줄이고, 폐오일이나 폐솔트에 의해 환경오염이 발생되는 것을 방지할 수 있는 장점이 있다.In addition, the electric boiler can use waste oil or waste salt, which is industrial waste, as the heat medium (2), thereby reducing the cost of treating industrial waste and preventing environmental pollution from being generated by waste oil or waste salt. There is an advantage to this.

본 실시예의 경우, 상기 내부탱크(8)에 하나의 전기히터(4)만을 장착하여 열매체(2)를 가열하는 전기보일러를 예시하였으나, 공장 등에서 사용하는 산업용 보일러의 경우, 내부탱크(8)에 다수개의 전기히터와, 교반기를 장착하여, 이 교반기로 열매체(2)를 교반하도록 하는 것도 가능하다. 또한, 상기 내부탱크(8)의 일측에는 도시안된 별도의 신축탱크를 더 구비하여, 내부탱크(8)에 저장된 열매체(2)가 열에 의해 팽창될 경우, 열매체(2)의 팽창양 만큼 이 신축탱크의 내부 체적이 변화되면서, 열매체(2)의 압력에 의해 내부탱크(8)가 손상되는 것을 방지할 수 있도록 구성하는 것이 바람직하다.In the present embodiment, an electric boiler for heating the heat medium 2 by mounting only one electric heater 4 in the inner tank 8 is illustrated, but in the case of an industrial boiler used in a factory, the inner tank 8 It is also possible to equip a plurality of electric heaters and a stirrer to agitate the heat medium 2 with this stirrer. In addition, one side of the inner tank (8) is further provided with a separate expansion tank (not shown), when the heat medium 2 stored in the inner tank 8 is expanded by heat, this expansion and contraction by the amount of expansion of the heat medium (2) As the internal volume of the tank is changed, it is preferable that the internal tank 8 is prevented from being damaged by the pressure of the heat medium 2.
