Description

유도 가열을 위한 전사필름이 부착된 인덕션 용기 및 그 제작방법{A INDUCTION CONTAINER STRUCTURE AND MANUFACTURE METHOD}Induction container with transfer film for induction heating and its manufacturing method {A INDUCTION CONTAINER STRUCTURE AND MANUFACTURE METHOD}

본 발명은 유도가열용 인덕션 용기에 관한 것으로서, 더욱 상세하게는 인덕션 렌지에 사용되는 용기의 열전도 효율을 극대화 할 수 있도록 하기 위항 용기 구조 및 그 제작방법에 관한 것이다.The present invention relates to an induction vessel for induction heating, and more particularly, to a vessel structure and a manufacturing method thereof for maximizing the heat conduction efficiency of the vessel used for the induction stove.

일반적으로 자력선을 이용한 인덕션 기구, 예를 들어 인덕션 렌지는 고효율의 자력선 유도기술을 응용한 것으로 자력이 발생되어 용기 바닥에 전기소용돌이 효과가 일어나 열을 발생시키는 직접가열방식을 구현한 조리 기구이다.Induction apparatus using magnetic lines, for example, induction stove is a high-efficiency magnetic line induction technology is applied to the cooking appliance that implements the direct heating method to generate heat by generating the magnetic force is generated by the electric swirl effect on the bottom of the container.

다시 말해, 인덕션 렌지는 용기 얹어지는 상판 저부에 설치된 코일에 전류를 흘려 보내면 이 코일에서 자력선이 발생하고, 이러한 자력선이 상판에 놓인 용기의 바닥을 통과하면서 용기의 재질에 포함된 저항성분 예컨데 철 성분에 의해 와류 전류가 생성된다.In other words, when the induction stove sends current to the coil installed on the bottom of the container, magnetic force lines are generated from the coil, and these magnetic force lines pass through the bottom of the container placed on the upper plate. By the eddy current is generated.

이러한 와류전류는 용기 자체만을 발열시켜 렌지의 상판은 달구어지지 않고, 용기만 뜨거워져, 종래의 간접가열방식 예를 들어 가스렌즈, 버너 등의 가열 기구에 비해 높은 안전성과 경제성이 우수하고, 불꽃이 없으므로 화상의 위험이 없는 장점을 가지고 있다.These eddy currents only heat the vessel itself, so that the top plate of the stove is not heated, only the vessel becomes hot, and has superior safety and economical efficiency compared to conventional heating mechanisms such as gas lenses and burners. Therefore, there is no risk of burns.

그러나, 이러한 인덕션 기구는 반드시 그에 알맞는 재질로 제작된 용기만을 사용하여야 하는 문제가 있다. However, there is a problem that such an induction mechanism must use only a container made of a suitable material.

예컨데 스텐레스 18-10, 18-8, 18-0이나 철로 된 주물용기 혹은 철법랑 등은 인덕션 용기로써 사용이 가능하나, 유리· 동· 알루미늄·스텐레스 100% 등으로 제작된 용기의 경우에는 물리적 특성상 인덕션 렌지에서 발생되는 자력선을 받아들이지 못하고 통과 시키기 때문에 사용이 불가능한 문제가 있다.For example, stainless steel 18-10, 18-8, 18-0 or steel casting containers or iron enamel can be used as induction containers, but in the case of containers made of 100% glass, copper, aluminum and stainless steel, There is a problem that cannot be used because the magnetic force generated in the induction range is not accepted.

따라서 근래에는 이러한 용기를 개량하여 인덕션 기구에 사용할 수 있도록 하고 있는데, 그 일예를 살펴보면 국내 특허 제410897호와 같이 알루미늄 용기의 바닥 전체 혹은 그 일부에 자력성이 있는 마그네틱 메탈을 삽입하여 저항에 따른 와류 전류가 발생하도록 하는 용기가 개발되고 있다.Therefore, in recent years, such a container has been improved to be used in an induction apparatus. As an example, as shown in Korean Patent No. 410897, magnetic magnetic metal is inserted into the entire or a part of the bottom of an aluminum container to vortex due to resistance. Containers have been developed to allow current to be generated.

그러나 이러한 용기는 생산 과정이 복잡하고, 생산에 따른 막대한 설비가 필요하며 사용 중 쉽게 찌그러지거나 더럽혀지는 문제가 있다.However, such a container has a problem in that the production process is complicated, requires huge equipment according to the production, and is easily crushed or soiled during use.

본 발명은 상기한 종래 인덕션 용기에서의 문제점을 개선하기 위해 제안된 것으로서, 비자성체 용기의 바닥에 전사 코팅되어지는 열전도층으로 인해 열전도효과를 극대화 할 수 있도록 하는데 목적이 있다.The present invention has been proposed to improve the problems of the conventional induction container, and an object thereof is to maximize the thermal conductivity effect due to the thermally conductive layer that is transferred and coated on the bottom of the non-magnetic container.

상기 목적을 이루기 위한 본 발명의 용기 제작방법은, 알루미늄, 은, 카본, 철, 소다, 마그네슘, 칼슘, 산화물, 규사, 카리, 크롬, 지르콘, 아연 성분이 포함된 혼합물을 전사필름의 일측면에 인쇄하여 열전도층을 형성시키는 열전도층 인쇄단계; 상기 열전도층이 인쇄된 전사필름을 60℃에서 4~5시간동안 건조시키는 건조단계; 상기 건조되어진 전사필름을 내열용기에 부착시키는 용기 부착단계; 상기 내열용기에 부착되어진 전사필름에 형성된 미세공기를 제거하는 미세공기 제거단계; 상기 전사필름이 부착되어진 용기를 가마에서 800~850℃ 온도로 2~3시간동안 소성시키는 소성단계;로 이루어짐을 특징으로 한다.The container manufacturing method of the present invention for achieving the above object, a mixture containing aluminum, silver, carbon, iron, soda, magnesium, calcium, oxide, silica, carry, chromium, zircon, zinc components on one side of the transfer film A thermal conductive layer printing step of printing to form a thermal conductive layer; A drying step of drying the transfer film printed with the thermal conductive layer at 60 ° C. for 4 to 5 hours; A container attachment step of attaching the dried transfer film to a heat resistant container; Removing the fine air formed on the transfer film attached to the heat resistant container; Characterized in that the firing step of firing the container to which the transfer film is attached for 2 to 3 hours at a temperature of 800 ~ 850 ℃ in the kiln.

이러한 본 발명은, 내열용기의 저면 및 측면에 열전도성을 극대화 시킬 수 있도록 다수의 열전도성 물질이 혼합되어진 열전도층이 형성되어진 전사필름이 부착 구비되어짐으로서, 인덕션 렌지를 이용한 음식물 조리시 용기의 열전도 효과를 극대화 하는 효과를 나타낸다.The present invention is provided with a transfer film having a heat conduction layer in which a plurality of heat conductive materials are mixed so as to maximize thermal conductivity on the bottom and side surfaces of the heat resistant container, and thus the heat conduction of the food cooking vessel using an induction stove. The effect is maximized.

In particular, the thermal conductive layer 11 is protected by the fluororesin coating layer 13. It can be done.

<건조>(ST 2)<Drying> (ST 2)

그리고, 건조가 완료되면 전사필름(10)을 물에 불려서 내열용기(1)의 외표면에 부착시키는 작업을 실시하게 된다.When the drying is completed, the transfer film 10 is soaked in water to attach to the outer surface of the heat-resistant container 1.

이때에는, 전사필름(10)을 일정시간동안 물에 불려서 부착력을 갖도록 한 상태에서 도 2에서와 같이 내열용기(1) 즉, 기물의 저면 및 측면에 각각 부착시킴으로서 용기의 열전도성 향상부위를 극대화 함이 바람직하다.At this time, the transfer film 10 is attached to the heat-resistant container 1, that is, the bottom and side of the substrate, respectively, as shown in FIG. It is preferable to.

한편, 내열용기(1)에 부착된 전사필름(10)에는 부착과정에서 미세공기층이 발생되어지게 됨으로, 이를 제거하기 위한 작업을 필요로 하게 된다.On the other hand, the transfer film 10 attached to the heat-resistant container (1) is generated because the micro-air layer in the attachment process, it is necessary to work to remove it.

<소성>(ST 5)<Firing> (ST 5)

이와 같이 전사필름(10)이 부착되어진 용기는 고온의 터널가마(킬링) 에서 800~850℃ 온도로 2~3시간동안 소성을 최종적으로 실시함으로서, 본 발명의 인덕션용 용기의 제작이 완료되어지게 된다.As described above, the container to which the transfer film 10 is attached is finally baked at a temperature of 800 to 850 ° C. for 2 to 3 hours in a high temperature tunnel kiln (killing), so that the production of the induction container of the present invention is completed. do.

이와 같은 과정을 통해 제작되어진 인덕션 내열용기(1)는, 열전도층(11)이 구비되어져 있는 전사필름(10)이 도 2의 저면 사시도에서와 같이 용기의 저면 뿐만 아니라 측벽면에도 부착 구비됨으로서 전체적인 열전도 효과가 극대화 되어질 수 있게 됨을 알 수 있다.The induction heat-resistant container 1 manufactured through the above process has the transfer film 10 having the heat conductive layer 11 attached to the side wall as well as the bottom of the container as shown in the bottom perspective view of FIG. 2. It can be seen that the heat conduction effect can be maximized.
