본 발명은 공진주파수 자동 변환기능을 가진 인덕션 히팅기에 관한 것으로서, 보다 구체적으로는 휴대가 용이하면서 녹슨 볼트 및 기계장치를 손쉽게 탈거하거나 기계 부품 등을 가열할 수 있는 공진주파수 자동 변환기능을 가진 인덕션 히팅기에 관한 것이다.The present invention relates to an induction heating device having an automatic resonance frequency conversion function, and more particularly, to an induction heating device having an automatic resonance frequency conversion function capable of easily removing a rusty bolt and a mechanical device, Lt; / RTI >

종래에 자동차용 메니폴더나 각종 사출물은 여러 너트와 같은 금속물들을 이용하여 결합될 수 있으며, 사출물들을 결합시키기 위한 방법으로 전자기 유도현상을 이용한 고주파 유도가열기를 사용하고 있다. 고주파 유도 가열기는 도체에 코일이 감긴 전자석으로 구성되는 것으로서, 코일에 교류전류를 통과시키면 코일에 시간에 따라 방향이 변하는 교류자기장이 형성되고, 도체에 교류자력이 가해지면 도체에는 전자기 유도현상에 의해 소용돌이 와전류가 발생하게 된다. 이때, 발생하는 소용돌이 와전류로 인해 발생되는 줄열에 의해서 물체가 가열된다.2. Description of the Related Art [0002] Conventionally, motor-operated folders and various molded articles can be combined using metal materials such as various nuts, and a high-frequency induction heater using electromagnetic induction is used as a method for coupling injection molded articles. The high frequency induction heater is composed of electromagnets with a coil wound around the conductor. When an alternating current is passed through the coil, an alternating magnetic field whose direction changes with time is formed in the coil. When AC magnetic force is applied to the conductor, Eddy currents are generated. At this time, the object is heated by the heat generated by the vortex eddy currents generated.

이와 같이, 고주파 유도가열기를 이용하여 사출물을 가열시키기 위해서는 코일 내부로 사출물을 이동시켜 위치시킨 다음 금속물을 가열하여 사출물의 인서 트홀로 압입시킴으로서 금속물을 사출물에 결합시켰었다.In this way, in order to heat the injection-molded article using the high-frequency induction heater, the injection-molded article is moved to the inside of the coil, and the metal article is heated and inserted into the insert hole of the injection-molded article.

그러나 사출물의 크기가 큰 경우에는 사출물을 유도가열기 내부로 위치시킬 수 없기 때문에 금속물을 결합하는 작업이 불가능하게 된다. 이로 인하여, 큰 사출물에 맞춰서 더 큰 고주파 유도가열기를 제작해야 하는 번거롭고 비경제적인 문제점이 있었다.However, when the size of the injection molding is large, it is impossible to place the injection molding inside the induction heating furnace, so that it is impossible to join the metal molding. As a result, there is a problem in that it is troublesome and uneconomical to manufacture a larger high frequency induction heater in accordance with a large injection molding.

또한, 사출물의 사용 연한이 만료되어 폐기시에는, 사출물에 결합되어 있는 너트와 같은 금속물들을 사출물로 부터 탈거시킨 다음 재활용을 위해 파쇄를 시키게 된다.Also, at the time of expiration of the use period of the injection molded article, metals such as nuts bonded to the injection molded article are removed from the injection molded article and then crushed for recycling.

이때, 사출물로부터 금속물을 분리하기 위해서 종래기술은, 전기인두를 사용하였었다. 즉, 전기인두를 사출물에 결합된 금속물과 접촉시켜서 전기인두에서 발생되는 열에 의해 금속물을 가열하면 금속물이 가열되면서 금속물 주변의 사출물이 용융되기 때문에 상기의 금속물을 집게 등으로 분리시킬 수 있었다.At this time, in order to separate the metal material from the injection product, an electric iron was used in the prior art. That is, when the metal shell is heated by the heat generated from the electric oven by bringing the electric ophthalmoscope into contact with the metal body coupled to the injection molded body, the metal body is heated and the molded body around the metal body is melted. I could.

그러나 전기인두를 사용하면 작업자가 직접 전기인두를 잡고 눌러주어야 하기 때문에 금속물을 가열하는데 많은 시간을 낭비하여야 했고 수작업인 만큼 결합되는 금속물의 수평도를 맞추기도 힘들어 불량의 발생이 속출하였으며 더딘 작업에 의해 생산성도 저하되는 문제점이 있었다.However, since the electric iron has to be held by the operator to hold the electric iron directly, it is necessary to waste a lot of time in heating the metal water, and it is difficult to adjust the horizontal degree of the metal to be combined with the manual iron. The productivity is lowered.

도 1 내지 도 3을 참조하여 설명하면, 공진주파수 자동 변환기능을 가진 인덕션 히팅기(10)는 배터리(100), 인버터(200), 전압가변부(300), 코일부(400), 공진 콘덴서(500), 전류 증폭 트랜스(600), 제어부(700)를 포함하여 구성된다.1 to 3, an induction heating apparatus 10 having an automatic resonance frequency conversion function includes a battery 100, an inverter 200, a voltage variable unit 300, a coil unit 400, a resonance capacitor (500), a current amplification transformer (600), and a controller (700).

배터리(100)는 리튬이온 또는 납축전지 중 하나로 형성되어 전류를 공급하는 역할을 하며, 본 발명의 특징에 따라 사용전에 충전되어 사용할 수 있다. 이때, BMS(Battery management system)을 구비하고, 슈퍼캐패시터를 더 포함하여 배터리(100)와 함께 직류전류를 공급할 수 있다.The battery 100 is formed of one of lithium-ion or lead-acid batteries and supplies current. The battery 100 may be charged before use according to the characteristics of the present invention. At this time, a battery management system (BMS) is provided and a super capacitor is further included to supply the DC current with the battery 100.

슈퍼캐패시터는 급속 충방전이 가능하고, 충방전 효율이 높으며, 거의 무한대에 가까운 충방전 사이클을 가진다. 또한, 급격한 충방전이 가능하게 임피던스가 낮고, 센서 및 기타 부가적인 회로를 간단하게 할 수 있어, 배터리(100)와 함께 효율적으로 전력을 제공할 수 있다. BMS(Battery management system)를 통하여 배터리 및 슈패캐패시터를 효율적으로 관리하게 된다. The super capacitor is capable of rapid charge / discharge, has high charging / discharging efficiency, and has a charge / discharge cycle close to almost infinite. In addition, the impedance can be low enough to allow rapid charging and discharging, the sensor and other additional circuits can be simplified, and the battery 100 can be efficiently supplied with power. The BMS (battery management system) enables efficient management of battery and supercapacitor.

배터리(100)는 DC 충전방식을 채택하여 장소에 상관없이 충방전이 가능하기 때문에 휴대성을 증대시킬 수 있게 된다.The battery 100 adopts a DC charging method, so that charging and discharging are possible regardless of a place, so that the portability can be increased.

인버터(200)는 배터리(100)에 저장된 직류전류를 스위칭하여 고주파 교류 전류로 변환한다.The inverter 200 switches the direct current stored in the battery 100 and converts it into a high frequency alternating current.

전압가변부(300)는 고주파 교류 전류를 피가열 금속의 등가 저항에 맞추어 매칭시킨다.The voltage variable unit 300 matches the high frequency alternating current with the equivalent resistance of the metal to be heated.

코일부(400)는 원형 유도가열 코일로 형성될 수 있으며, 인버터(200)를 통해 발생한 고주파 교류 전류를 열로 발생시켜 피가열체를 가열한다. 코일부(400)는 피가열 금속을 감싸도록 형성된다. 코일부(400)는 전술한 바와 같이 유도 가열에 의해서 열을 발생시킨다. 이때, 코일부(400)에서 발열되는 열은 사용자의 선택에 따라 변경될 수 있지만, 200℃이내로 발열 가능하도록 설계되는 것이 바람직하다. 발열온도를 200℃를 초과하도록 설계되는 경우, 전체적인 시스템 및 크기가 커지기 때문에 휴대성이 저하될 수 있기 때문이다.The coil part 400 may be formed by a circular induction heating coil and generates a high frequency alternating current generated through the inverter 200 as heat to heat the heating target. The coil part 400 is formed so as to surround the metal to be heated. The coil part 400 generates heat by induction heating as described above. At this time, the heat generated in the coil part 400 may be changed according to the user's choice, but it is desirable that the heat is generated within 200 ° C. If the heat generation temperature is designed to exceed 200 DEG C, the overall system and size become large, and the portability may deteriorate.

유도 가열은 전자유도 작용에 의한 것으로서, 교류 전류가 흐르는 코일속에 위치하는 금속 등의 도전체는 와전류 손실과 히스테리시트(Hysteresis) 손실의 저항에 의하여 열이 발생한다. 이와 같이 발생하는 열에너지를 이용하여 모재를 가열하는 것을 말한다. 특히 고주파 전류를 이용하는 것을 고주파 유도 가열(high-frequency induction heating)이라 한다. 이러한 고주파 유도 가열은 도체의 직접가열 또는 국부가열이 가능하고, 에너지 밀도가 높으며, 불꽃이 방출되지 않으며 용접 중 발생하는 퓸(fume)이 저감되는 특징이 있다.Induction heating is caused by an electromagnetic induction action, and a conductor such as a metal placed in a coil through which an alternating current flows generates heat due to resistance of eddy current loss and hysteresis loss. And heating the base material by using the heat energy generated in this manner. In particular, the use of a high frequency current is referred to as high-frequency induction heating. This high frequency induction heating is capable of direct heating of the conductor or locally heating, has high energy density, does not emit flame, and reduces fumes generated during welding.

이때, 코일부(400)는 피가열 금속보다 크게 형성되어 피가열 금속의 축을 따라 나선형상으로 소정 깊이만큼 감싸도록 형성될 수 있다. 따라서 코일부(400)는 다양한 직경으로 형성되는 것이 바람직하며, 피가열 금속의 크기에 따라 선택적으로 교체하여 사용할 수 있기 때문에 가열대상 및 크게 상관없이 다양하게 적용할 수 있다.At this time, the coil part 400 may be formed to be larger than the metal to be heated, and may be formed to have a spiral shape along the axis of the metal to be heated to a predetermined depth. Therefore, it is preferable that the coil part 400 is formed in various diameters, and the coil part 400 can be selectively used depending on the size of the metal to be heated.

공진 콘덴서(500)는 고주파 교류 전류의 에너지 증폭과 역률을 조정한다. 이로 인하여, 코일부(400)가 필요로 하는 무효전력을 인버터(200)가 공진 콘덴서(500)에 저장된 에너지로 공급하게 함으로써 인버터(200)의 역률을 개선하는 것이다. The resonance capacitor 500 adjusts the energy amplification and the power factor of the high frequency alternating current. This improves the power factor of the inverter 200 by allowing the inverter 200 to supply the reactive power required by the coil part 400 to the energy stored in the resonant capacitor 500.
