Abstract

본 고안은 워킹코일의 구조를 턴 수를 많게 할 수 있도록 하여 비자성 금속도 가열시킬 수 있도록 한 유도가열조리기의 유도가열코일에 관한 것이다.The present invention relates to an induction heating coil of an induction heating cooker capable of heating the structure of the working coil to heat the non-magnetic metal.

종래의 유도가열조리기의 워킹코일은 리쯔구조로 되어 턴수를 많이 할 수 없어 비자성 가열용기는 가열시킬 수 없던 점을 감안하여 본 고안은 워킹코일이 얇은 테이프 형태를 갖는 여러겹의 절연동박이 원형으로 감긴 구조를 갖도록 함으로써 높은 전력을 얻을 수 있게 되어 유도가열조리기에서 비자성 가열용기도 가열시킬 수 있도록 한 것이다.In consideration of the fact that the working coil of the conventional induction heating cooker has a Litz structure and cannot turn a lot, the nonmagnetic heating vessel cannot be heated. By having a structure wound around, it is possible to obtain a high power to heat the non-magnetic heating vessel in the induction cooker.

본 고안은 유도가열조리기의 유도가열코일에 관한 것으로, 더욱 상세하게는 워킹코일의 구조를 턴 수를 많게 할 수 있도록 하여 비자성 금속재질의 용기도 가열시킬 수 있도록 한 유도가열조리기의 유도가열코일에 관한 것이다.The present invention relates to an induction heating coil of an induction heating cooker, and more particularly, an induction heating cooker of an induction heating cooker capable of heating a container made of a non-magnetic metal by increasing the number of turns of the working coil. It is about.

제1도는 일반적인 유도가열조리기의 구조를 도시한 것으로, 파워 코드가 꽂혀 유도가열조리기에 파워가 인가되고 유도조리그이 세라믹판(2)에 가열용기(1)를 올려놓고 스타트키이를 입력하여 스타트를 하게 되면 이 신호가 제어회로(4)에 전달되어 적절한 파워를 낼 수 있게 적당한 주파수를 구동회로(5)에 전달한다.1 shows the structure of a general induction heating cooker, the power cord is plugged in, power is applied to the induction cooking cooker, and the induction cooker puts the heating vessel (1) on the ceramic plate (2) and enters the start key to start. This signal is transmitted to the control circuit 4 to transmit the appropriate frequency to the drive circuit 5 to produce a proper power.

상기 구동회로(5)에서는 LC 공진이 일어날 수 있도록 스위칭을 해줌으로써 워킹코일(3)에 자계가 형성되어 가열용기(1)를 가열시켜주게 된다.In the driving circuit 5, the magnetic field is formed in the working coil 3 by switching so that LC resonance occurs, thereby heating the heating vessel 1.

그리고 제2도 (a)는 상기 워킹코일(3)의 정면도를 나타낸 것이고, (b)는 부분 사시도를 나타낸 것이고, (b)에 나타내었듯이 종래의 워킹코일(3)은 리쯔 와이어 구조를 갖는다.2 (a) shows a front view of the working coil 3, (b) shows a partial perspective view, and as shown in (b), the conventional working coil 3 has a litz wire structure.

그러나 상기와 같이 워킹코일의 리쯔 구조로는 턴수를 많이 감지 못하므로 비자성 금속을 가열시키기 위해 전력을 높여줄 수 없는 단점이 있었다.However, as described above, the LIT structure of the working coil does not detect a large number of turns, so there is a disadvantage in that the power cannot be increased to heat the nonmagnetic metal.

본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 유도가열조리기의 유도가열코일이 0.1mm의 두께를 가지는 얇은 테이프 형태의 절연동박을 복수겹으로 중첩하고, 이를 소용돌이 형태로 감아돌려 열효율을 향상시킬 수 있도록 한 유도가열조리기의 유도가열코일을 제공함에 있다.The present invention is to solve this problem, the object of the present invention is the induction heating coil induction heating coil overlaps a plurality of insulated thin copper foil insulated copper foil having a thickness of 0.1mm, and it is wound in a spiral form to heat efficiency To provide an induction heating coil of an induction heating cooker to improve the.

이러한 목적을 달성하기 위한 본 고안의 특징은 0.1mm의 두께를 가지는 얇은 테이프 형태의 절연동박을 복수겹으로 중첩하고, 이를 소용돌이 형태로 감아돌려 열효율을 향상시킬 수 있도록 한 유도가열조리기의 유도가열코일에 있다.A feature of the present invention for achieving the above object is the induction heating coil of an induction heating cooker to improve the thermal efficiency by overlapping a plurality of layers of insulating copper foil in the form of a thin tape having a thickness of 0.1mm, and winding it in a spiral form Is in.

이하, 본 고안의 일실시예를 첨부도면을 참조로 하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 고안에 따른 워킹코일의 정면도를 나타낸 것으로, 이는 제4도(a),(b)와 같이 얇은 테이프 형태를 갖는 여러겹의 절연동박을 와권형(소용돌이형)으로 감긴 구조를 갖으며, 이때 절연동박의 지름은 0.1mm로 한다.3 is a front view of the working coil according to the present invention, which has a structure in which a plurality of insulated copper foils having a thin tape shape are wound in a spiral winding type (swirl type) as shown in FIGS. 4 (a) and 4 (b). In this case, the diameter of the insulated copper foil is 0.1mm.

상기와 같은 구조의 워킹코일을 이용하면 다음과 같이 전력을 상승시킬 수 있어 비자성 금속재질의 용기도 가열시킬 수 있게 된다.When the working coil having the structure described above is used, the power can be increased as follows, and the non-magnetic metal container can be heated.

우선, 전력(P)은 유도가열 이론식에 의하면 다음과 같다.First, the power P is as follows according to the induction heating equation.

P=k(μρf)×(NI)2 P = k (μρf) × (NI) 2

여기서, μ:비투자율, ρ:저항률, f;주파수, N:턴 수, I:전류이다.Where μ is the specific permeability, ρ is the resistivity, f is the frequency, N is the number of turns, and I is the current.

또한, 두 재질 즉, 자성인 철과 비자성인 알루미늄의 저항률과 비투자율은 다음 표와 같다.In addition, the resistivity and specific permeability of the two materials, magnetic iron and nonmagnetic aluminum, are shown in the following table.

따라서 철의 μρ는 2613, 알루미늄의 μρ는 2.41이 되고 두 재질을 비교하면 약 1000:1정도가 되어 동일 조건하에서 알루미늄 재질은 철재에 비해 약 1/33정도로 적은 전력이 발생하게 된다.Therefore, μμ of iron is 2613, μρ of aluminum is 2.41, and when the two materials are compared, it is about 1000: 1. Under the same conditions, aluminum generates about 1/33 less power than iron.

따라서 유도가열조리기에서 비자성인 가열용기를 가열시키기 위해서는 유도가열코일의 암페어나 턴수를 높여주어야 한다.Therefore, in order to heat a non-magnetic heating container in an induction heating cooker, it is necessary to increase the ampere or turn number of the induction heating coil.

암페어를 높이는 것은 코일의 온도 한계성이 있고 또 스위칭소자의 한계성이 있으므로 코일의 턴수를 높여야 하나 현재 가열용기의 반지름은 약 100mm로 한정되고 종래의 리쯔 와이어의 지름은 약 3mm이므로 약 30회를 감을 수 있으나, 본 고안에 따른 절연동박비는 약 0.1mm이므로 1000회를 감을 수 있으므로 종래의 리쯔 와이어에 비해 약 33배의 전력을 상승시킬 수 있으므로 비자성 가열용기도 가열시킬 수 있게 된다.Increasing the amperage has a coil temperature limit and a switching element limit, so the number of turns of the coil should be increased, but the radius of the heating vessel is currently limited to about 100mm and the diameter of the conventional litz wire is about 3mm, so it can be wound about 30 times. However, since the insulation copper foil ratio according to the present invention is about 0.1 mm and can be wound 1000 times, the non-magnetic heating vessel can also be heated since the power can be increased by about 33 times compared to the conventional Litz wire.

이상에서 살펴본 바와 같이 본 고안은 유도가열조리기의 유도가열코일이 얇은 테이프 형태를 갖는 여러겹의 절연동박이 원형으로 감긴 구조를 갖도록 함으로써 높은 전력을 얻을 수 있게 되어 유도가열조리기에서 비자성 금속재질의 가열용기도 가열시킬 수 있게 된다.As described above, the present invention allows the induction heating coil of the induction heating cooker to have a structure in which a plurality of insulated copper foils having a thin tape shape are wound in a circular shape, thereby obtaining high power. The heating vessel can also be heated.
