본 발명은 고주파유도가열을 이용한 온풍장치에 관한 것으로서, 좀더 상세하게는 통상적으로 전기 소모량이 적은 고주파 유도가열을 이용하여 열매체유를 가열시키고, 열매체유의 순환으로서 온풍을 구현하도록 한 장치에 있어, 열매체유의 온도(끓는 온도)를 짧은 시간 내에 가속화시킬 수 있는 구조를 채택하여 이상적인 온풍을 구현할 수 있도록 한 것이다.The present invention relates to a warm air device using high frequency induction heating, and more particularly, in a device to heat the heat medium oil using high frequency induction heating with low electricity consumption, and to implement warm air as a circulation of the heat medium oil, By adopting a structure that can accelerate the temperature (boiling temperature) of oil in a short time, the ideal warm air can be achieved.

일반적으로 알려져 있는 온풍기는 석유등과 같은 에너지유를 연소 가열하여 연소열로서 온풍을 구현하거나, 전기가열히터를 히터를 이용하여 열을 얻어 온풍을 실시하는 방식의 난방장치이다.Generally known hot air heater is a heating device that implements warm air as combustion heat by burning and heating energy oil such as petroleum, or by heating the electric heating heater by using a heater.

석유와 같은 연소에너지의 사용은 열 효율은 좋으나, 공기가 오염되는 문제점이 있고, 항상 필요로 하는 양의 에너지를 공급시켜 주어야 하는 폐단이 있다.The use of combustion energy such as petroleum has good thermal efficiency, but there is a problem that air is polluted and there is a need to supply the required amount of energy at all times.

대체적으로는 가정이나 사무실 등지에서 전기를 이용하여 사용하기 편리한 전기제품이 대부분이며, 이러한 제품의 기본적인 구조를 살피면, 첨부된 도 1에서와 같이, 전원공급에 의해 열을 발생시키는 가열히터(a), 가열된 열을 일방향으로 불어 송풍시키는 송풍 팬(b)과, 이들을 수용하는 본체로 구성되며, 온도의 제어 송풍력을 제어할 수 있는 제어부(c)로 간략하게 구성된다.In general, most home appliances are easy to use electrical appliances in homes and offices, and if you look at the basic structure of these products, as shown in Figure 1 attached to the heating heater for generating heat by the power supply (a) And a blower fan (b) that blows and blows the heated heat in one direction, and a control unit (c) which can control the control blow force of the temperature.

그러나, 상기와 같은 온풍기는 전기가열히터의 전력소모량이 높아 현재에는 상기와 같이 직접적으로 작용하여 열을 발생하는 전기가열히터 대신 고주파 유도가 열을 이용한 온풍기 등이 개발되고 있다.However, such a hot air heater has a high power consumption of the electric heating heater, and a hot air heater using high frequency induction heating has been developed instead of the electric heating heater which directly acts as described above.

참고로 고주파 유도가열은 코일(coil)에 둘러싸인 피가열 물에 고주파 전류를 흘리면 전류가 유도되고 이에 따라 발생되는 열에 의해 직접 가열되는 것으로서, 자동차부품 및 기계부품, 강관이나 강선, 강판이나 강괴, 조선 및 전기부품 등 금속류를 가열하여 단조, 용해, 열처리, 열가공 등에 범용적으로 사용되고 있는 가열수단이다.For reference, high-frequency induction heating is induced by high-frequency current flowing through the coiled water to be heated, and is directly heated by the heat generated by the high-frequency induction. It is used for automobile parts and mechanical parts, steel pipes or steel wires, steel sheets or steel bars, shipbuilding. And heating means commonly used for heating, forging, melting, heat treatment, and heat processing metals such as electric parts.

고주파유도가열의 사용은 청정에너지임과 동시에, 전기를 이용하여 우선 공해가 없고 첨단의 고속 반도체를 사용하기 때문에 에너지 효율이 높으며 정밀한 온도제어와 소형화와 자동화를 동시에 추구할 수 있고, 최소의 비용으로 필요한 부분을 가열/운영할 수 있는 이점이 있다.The use of high-frequency induction heating is clean energy, and there is no pollution first using electricity, and high-speed semiconductors are used, so energy efficiency is high, precise temperature control, miniaturization and automation can be pursued simultaneously, and at a minimum cost. This has the advantage of heating / operating the necessary part.

이러한 점에서 고주파유도가열을 이용한 온풍기의 개발은 에너지소비율은 낮으면서 열효율은 높일 수 있는 제품의 개발이 시급한 실정이다.In this regard, the development of a hot air blower using high frequency induction heating is urgently needed to develop a product that has a low energy consumption rate and a high thermal efficiency.

The high frequency induction heater 20 has an induction coil 22 connected to the high frequency oscillator 21 wound around the bobbin 23, and a heat insulating material 24 is wrapped around its outer circumference, while a cylindrical heating tube is formed from the outside thereof. 25 are spaced apart from each other, and heating rings 26 at equal intervals are attached to the outer circumference of the heating tube 25 and fixedly installed in the heat storage tank 10.

한편, 상기 가열링(26)은 가열관(25)의 외경에 밀착되는 링 형상으로, 원주에 원형타공(26a)이 다수개 배열 형성된다.On the other hand, the heating ring 26 has a ring shape in close contact with the outer diameter of the heating tube 25, a plurality of circular perforations 26a are formed in the circumference.

이와 같이 구성된 본 발명인 고주파 유도가열을 이용한 온풍장치의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effect of the warm air device using the high frequency induction heating of the present invention configured as described above are as follows.

먼저, 축열조(10) 내에 고정 설치된 고주파유도가열기(20)에 대해 열매체유(A)가 설정된 양만큼 담겨 진 상태에서 고주파유도가열기(20)에 전원을 인가하여 준다.First, power is applied to the high frequency induction heater 20 in a state in which the heat medium oil A is contained by a predetermined amount with respect to the high frequency induction heater 20 fixedly installed in the heat storage tank 10.

전원의 인가로 고주파 발진기(21)로부터 발생된 전압은 보빈(23)에 나선형태로 감겨진 유도코일(22)에 전류를 흘려보내고, 그 외측에 감싸진 단열재(24)의 외부로는 유도전류의 가열현상이 발생되어 가열관(25)을 가열하게 된다.The voltage generated from the high frequency oscillator 21 by the application of power supplies a current to the induction coil 22 wound in a spiral shape on the bobbin 23, and induced current to the outside of the heat insulating material 24 wrapped on the outside thereof. Heating phenomenon occurs to heat the heating tube (25).

상기 가열관(25)의 가열과 함께 그 외측 둘레에 등 간격지게 설치된 가열링(26)으로부터는 가열관(25)으로부터 열을 전이 받고, 전이된 열에 의해 열매체유(A)는 가열관(25)과 함께 가열한다.Heat is transferred from the heating tube 25 from the heating ring 26 equally spaced around the outer side of the heating tube 25 together with the heating of the heating tube 25, and the heat medium oil A is heated by the transferred tube 25. Heating).

상기와 같이 가열링(26)으로부터 열매체유(A)가 가열됨에 있어, 가열링(26)의 원주상에 형성된 다수의 원형타공(26a)으로부터 발생되는 온도 상승조건에서 기포가 발생하게 된다.As the heat medium oil A is heated from the heating ring 26 as described above, bubbles are generated in a temperature rising condition generated from a plurality of circular perforations 26a formed on the circumference of the heating ring 26.

상기와 같은 온도조건에서는 축열조(10)의 일측면에 설치된 초음파 진동발생기(13)가 가동되며, 이때 발생되는 초음파 진동은 축열조(10) 내에 담겨 진 열매체유(A)에 전달하게 되며, 결국 상기 가열링(26)의 원형타공(26a)으로부터 발생된 기포를 털어내는 작용을 한다.Under the above temperature conditions, the ultrasonic vibration generator 13 installed on one side of the heat storage tank 10 is operated, and the ultrasonic vibration generated at this time is transmitted to the heat medium oil A contained in the heat storage tank 10. It functions to shake off bubbles generated from the circular perforations 26a of the heating ring 26.

이어서 설정온도로 가열된 조건의 열매체유(A)는 축열조(10)의 출구측(12)을 통해 순환펌프(30)로서 이와 연결된 라디에이터(40)를 거치면서 송풍 팬(41)의 작동으로 더운 바람을 발생시켜 실내 측에 더운 공기를 제공할 수 있게 된다.Subsequently, the heat medium oil A under the condition heated to the set temperature is heated by the operation of the blowing fan 41 while passing through the radiator 40 connected thereto as the circulation pump 30 through the outlet side 12 of the heat storage tank 10. By generating wind, it is possible to provide hot air to the indoor side.

상기 라디에이터(40)를 통해 열교환 하면서 일방향으로 진행되는 열매체유(A)는 다시 순환파이프(P1)를 통해 축열조(10)의 유입구(11)를 거쳐 재가열되어 상기와 같이 순환하는 방식으로 실내를 난방할 수 있게 된다.Heat transfer oil (A) in one direction while heat exchange through the radiator 40 is reheated through the inlet 11 of the heat storage tank 10 again through the circulation pipe (P1) to heat the room in a circulating manner as described above You can do it.

이상에서와 같이 본 발명에 의한 온풍장치는 전력 소비량이 낮은 고주파유도가열을 이용하여 열매체유를 빠른 시간 내에 온도를 가속화하고, 이를 라디에이터로 순환시켜 열교환 한 열을 더운 공기로서 실내에 제공할 수 있게 함으로서, 가열히터를 통해 발산되는 열을 이용한 기존의 온풍장치에 비해 경제적이면서 효과적인 난방을 구가할 수 있는 효과가 있다.As described above, the warm air device according to the present invention uses high frequency induction heating with low power consumption to accelerate the temperature of the heat medium oil in a short time, and circulate it to the radiator to provide heat exchanged heat to the room as hot air. By doing so, there is an effect that can be economical and effective heating compared to the existing warm air using the heat emitted through the heating heater.
