Description
본 고안은 유도가열을 이용한 전기보일러에 관한 것으로서, 보다 상세하게는 난방수 배관을 직접 유도가열하여, 간단한 구조로 높은 난방효율을 나타내는 유도가열을 이용한 전기보일러에 관한 것이다.The present invention relates to an electric boiler using induction heating, and more particularly, to an electric boiler using induction heating, which indirectly heats a heating water pipe and exhibits high heating efficiency with a simple structure.
일반적으로, 유도가열형 전기보일러는 유도기전류를 이용하여 난방수를 가열하는 전기보일러로서, 종래 축열식 전기보일러에 비해 설치비용이 저렴하고, 상시 원하는 난방온도를 얻을 수 있는 장점이 있어, 최근 사용이 증가하고 있다.In general, the induction heating type electric boiler is an electric boiler that heats the heating water by using an induction current, and the installation cost is cheaper than the conventional heat storage electric boiler, and the desired heating temperature is always obtained. It is increasing.
도 1은 국내실용신안공개공보 실1989-2739호에 개시된 유도가열형 전기보일러의 일예를 보인 것이다. 이를 참조하면, 종래 유도가열형 전기보일러는 냉수유입관(10)과 온수유출관(12)이 구비된 금속재질의 탱크(14) 외부에 나선형으로 코일(16)을 권취한 내통(18)을 결합시키고, 코일(16)의 외부를 절연재(20)로 밀폐되게 도포하여 구성된다. 이러한 유도가열형 전기보일러는 코일(16)에 전류를 인가하면, 금속재질의 탱크(14) 표면에 유도기전류가 발생되면서 탱크(14)가 발열되어 내부의 난방수를 가열하게 된다.Figure 1 shows an example of the induction heating type electric boiler disclosed in Korean Utility Model Publication No. 1989-2739. Referring to this, the conventional induction heating type electric boiler has an inner cylinder 18 in which the coil 16 is spirally wound outside the metal tank 14 provided with the cold water inlet tube 10 and the hot water outlet tube 12. It is configured to bond and apply to seal the outside of the coil 16 with the insulating material (20). When the induction heating type electric boiler applies a current to the coil 16, an inductor current is generated on the surface of the metal tank 14 to heat the tank 14 to heat the heating water therein.
그러나, 탱크(14)의 내벽면에서는 난방수가 쉽게 가열되는 반면, 탱크(14)의 중심부로 가면서 열전도율이 크게 저하되어, 종래 난방수를 연소열에 의해 직접 가열하는 방식에 비해 발열효과가 떨어지는 문제점이 발생되고 있다. 또한, 탱크(14)내부의 난방수를 일정 온도로 끌어올리기까지 많은 시간을 필요로 하는 문제점이 있다. 또한, 도 1에 도시된 바와 같이, 탱크(14) 내부에 예열관(22)을 구비하여, 냉수의 온도를 서서히 증가시킨다 하여도, 예열관(22)이 탱크(14) 내부에 수용되는 온수에 의하여 2차적으로 가열됨으로써, 상기와 같은 탱크 가열방식의 유도가열형 전기보일러의 원천적인 문제점은 여전히 존재하고 있다고 하겠다.However, while the heating water is easily heated on the inner wall surface of the tank 14, the thermal conductivity is greatly reduced as it goes to the center of the tank 14, the heat generation effect is lower than the conventional method of heating the heating water directly by combustion heat. It is occurring. In addition, there is a problem in that a large amount of time is required to raise the heating water in the tank 14 to a predetermined temperature. In addition, as shown in FIG. 1, the preheating tube 22 is provided inside the tank 14 so that the preheating tube 22 is accommodated inside the tank 14 even if the temperature of the cold water is gradually increased. By secondary heating, the original problem of the induction heating type electric boiler of the tank heating method as described above will still exist.
본 고안은 상기의 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 난방수가 경유되는 배관에 직접 유도기전류를 발생시켜, 별도의 열전달 매개체 없이 난방수 배관을 직접 유도가열시킴으로써, 간단한 구조로 높은 난방효과를 기대할 수 있으며, 냉수를 보다 신속하게 가열할 수 있는 구조로 이루어진 유도가열을 이용한 전기보일러를 제공하는 것이다.The present invention is to solve the above problems, the object of the present invention is to generate an inductor current directly in the piping via the heating water, induction heating the heating water pipe directly without a separate heat transfer medium, high heating effect with a simple structure It can be expected to provide an electric boiler using induction heating made of a structure that can heat cold water more quickly.

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.
도 2는 본 고안에 따른 유도가열을 이용한 전기보일러의 분해사시도로서, 각 구성품이 분리된 상태를 도시한 것이다. 이를 참조하면, 본 고안의 전기보일러는 내부에 둘레부에 코일(50)이 권취된 내통체(55)가 구비되며, 이 내통체(55)의 외부에는 상기 코일(50)을 절연시키기 위한 절연통체(60)가 결합되며, 이 절연통체(60)의 외주면에 난방수파이프(65)가 나선형으로 권취되어 구성된다. 상기 내통체(55)는 코일(50)을 권취하기 위한 드럼 역할을 하는 것으로서, 합성수지 재질을 원통형상으로 성형하여 제조된다. 상기 코일(50)은 도시안된 전원공급장치에 연결된다. 여기서, 전원공급장치는 설계자가 통상 알려진 고주파 전원장치를 임의로 선택하여 실시할 수 있는 것으로, 자세한 설명은 생략하겠다. 상기 난방수파이프(65)는 상기 절연통체(60)에 의해 코일(50)과 상호 절연되도록 배치되는 것으로, 전원공급장치에서 코일(50)에 전원을 공급하여 코일(50)을 통해 1차전류가 흐르면, 난방수파이프(65)의 표면에는 전자기유도 현상에 의해 유도된 2차전류가 발생된다. 따라서, 난방수파이프(65)는 줄열에 의해 유도가열되면서 내부에 흐르는 난방수를 가열한다. 이때, 난방수의 발열온도는 코일(50)의 권선수와 난방수파이프(65)의 권취 횟수를 조절하거나, 코일(50)에 흐르는 1차측 전류를 조절하여 설정할 수 있다. 바람직하게, 난방수파이프(65)로는 니켈이나 크롬 등과 같이 투자율이 높은 금속재 파이프가 선택된다. 이때, 니켈이나 크롬 등과 같은 고투자율 소재로 이루어진 금속재 파이프는 절연통체(60)에 권취되는 부분만 선택적으로 사용될 수도 있다.Figure 2 is an exploded perspective view of an electric boiler using induction heating according to the present invention, showing a state in which each component is separated. Referring to this, the electric boiler of the present invention is provided with an inner cylinder 55 in which a coil 50 is wound around its inner portion, and an insulation for insulating the coil 50 outside the inner cylinder 55. The cylinder 60 is coupled, and the heating water pipe 65 is spirally wound on the outer circumferential surface of the insulated cylinder 60. The inner cylinder 55 serves as a drum for winding the coil 50, and is manufactured by molding a synthetic resin material into a cylindrical shape. The coil 50 is connected to a power supply not shown. Here, the power supply device may be implemented by the designer arbitrarily select a known high frequency power supply, detailed description thereof will be omitted. The heating water pipe 65 is arranged to be insulated from the coil 50 by the insulating cylinder 60, the power supply to supply the coil 50 to the primary current through the coil 50 Flows, the secondary current induced by the electromagnetic induction phenomenon is generated on the surface of the heating water pipe (65). Therefore, the heating water pipe 65 heats the heating water flowing therein while induction heating by Joule heat. In this case, the heating temperature of the heating water may be set by adjusting the number of windings of the coil 50 and the number of windings of the heating water pipe 65 or by adjusting the primary current flowing through the coil 50. Preferably, as the heating water pipe 65, a metal pipe having a high permeability such as nickel or chromium is selected. At this time, the metal pipe made of a high permeability material such as nickel or chromium may be selectively used only a portion wound around the insulating cylinder (60).
도 3에 도시된 단면도를 참조하면, 상기 난방수파이프(65)의 난방수유입부(70)와 난방수유출부(75)에는 각각 소정 구간 절연관(80)이 연결된다. 도 3에서 절연관(80)은 관연결구로 제공된다. 이와 같이 절연관(80)이 연결됨으로써, 절연통체(60) 외주면에 권취된 난방수파이프(65)에 인가되는 유도전류가 난방수유입부(70)와 난방수유출부(80) 측으로 전달되는 것을 방지할 수 있다. 따라서, 감전이나 누전 등의 사고를 방지할 수 있게 된다.Referring to the cross-sectional view shown in FIG. 3, a predetermined section insulating tube 80 is connected to the heating water inlet 70 and the heating water outlet 75 of the heating water pipe 65, respectively. Insulation tube 80 in Figure 3 is provided as a tube connector. As the insulated tube 80 is connected in this way, an induced current applied to the heating water pipe 65 wound around the outer circumferential surface of the insulating cylinder 60 is transmitted to the heating water inlet 70 and the heating water outlet 80. Can be prevented. Therefore, an accident such as an electric shock or a short circuit can be prevented.

That is, as the structure in which the heating water pipe 65 is directly inductively heated without a separate heat transfer medium, the heating water pipe 65 can be configured very simply, for example, by adjusting the number of windings of the heating water pipe 65, The heating water can be heated to a high temperature quickly. Therefore, a high efficiency heating effect can be expected in a small system, as well as a reduction in installation cost and convenient maintenance.
