Description
본 발명은 알루미늄 등으로 제작된 주방용 조리용기에 전사되어 인덕션 기구에서 발생하는 자력선을 유도하여 조리용기에 직접 가열이 이루어지도록 하는 전자유도가열 방식의 주방용 조리용기 및 그 제조방법에 관한 것으로써, 특히 조리용기의 바닥면에 디자인이 가능하고 가열효율이 높으며 에너지밀도가 높아 조리시간을 단축시킬 수 있도록 한 전자유도가열 방식의 주방용조리용기 제조 및 그 제조방법에 관한 것이다.The present invention relates to a cooking container for a kitchen of an electromagnetic induction heating type which is transferred to a kitchen cooking container made of aluminum or the like and induces a magnetic force line generated in the induction device to directly heat the cooking container, And more particularly, to a manufacturing method of a cooking cavity for a kitchen of an electromagnetic induction heating type which is capable of designing a bottom surface of the cooking cavity and has a high heating efficiency and a high energy density to shorten the cooking time.
일반적으로 자력선을 이용한 인덕션 기구, 예를 들어 인덕션 렌즈는 고효율의 자력선 유도기술을 응용한 것으로 자력이 발생되어 용기 바닥에 전기소용돌이 효과가 일어나 열을 발생시키는 직접가열방식을 구현한 조리 기구이다.Generally, an induction mechanism using a magnetic force line, for example, an induction lens, is a cooking appliance that implements a direct heating method in which a magnetic induction technique of high efficiency is applied and a magnetic force is generated and an electric vortex effect is generated at the bottom of the container to generate heat.
인덕션 렌지는 용기가 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.The induction range is generated by magnetic force lines generated by a current flowing through the coils installed on the bottom of the upper plate on which the container is placed. When the magnetic lines of force pass through the bottom of the container placed on the upper plate, A swirling current is generated.
이러한 와류전류는 용기 자체만을 발열시켜 렌지의 상판은 달구어지지 않고, 용기만 가열되어, 종래의 간접가열방식 예를들어 가스렌즈, 버너 등의 가열 기구에 비해 높은 안전성과 경제성이 우수하고, 불꽃이 없으므로 화상의 위험이 없는 장점을 가지고 있다.Such a swirling current causes only the container itself to generate heat, so that the top plate of the cooking stove is not heated, and only the container is heated, so that it is superior in safety and economical efficiency compared with the conventional indirect heating method, such as a gas lens and a burner. There is no risk of burning because there is no.
그러나, 이러한 인덕션 기구는 반드시 그에 알맞는 재질로 제작된 용기만을 사용하여야 하는 문제가 있다. 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 통과시키기 때문에 사용이 불가능한 문제가 있다.However, there is a problem that such an induction mechanism must use only a container made of a suitable material. For example, stainless steel 18-10, 18-8, 18-0 or ferrous castings or iron enamel can be used as induction vessels, but for vessels made of glass, copper, aluminum, stainless steel, etc., There is a problem that it can not be used because the magnetic force lines generated in the induction range can not be received and passed.
따라서 근래에는 이러한 용기를 개량하여 인덕션 기구에 사용할 수 있도록 하고 있는데, 그 일예로써 알루미늄 용기의 바닥 전체 혹은 그 일부에 자력성이 있는 마그네틱 메탈을 삽입하여 저항에 따른 와류전류가 발생하도록 하는 용기가 개발되고 있다.In recent years, such a container has been improved so that it can be used in an induction mechanism. For example, a container for generating a swirling current due to resistance by inserting a magnetic metal having magnetism into the entire bottom or a part of the aluminum container .
그러나 이러한 용기는 생산 과정이 복잡하고, 생산에 따른 막대한 설비가 필요하며 사용 중 알루미늄 용기와 마그네틱 메탈의 열팽창 차이로 용기의 반복된 사용시 변형이 되는 문제점이 있다.However, such a container has a complicated production process, requires a large amount of equipment according to production, and has a problem in that it is deformed during repeated use due to the difference in thermal expansion between the aluminum container and the magnetic metal during use.
본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로써, 조리용기의 바닥면에 디자인이 가능한 전자유도가열 방식의 주방용조리용기 및 그 제조방법을 제공하는 데 그 목적이 있다.It is an object of the present invention to provide an electronic induction heating type kitchen cooking container which can be designed on the bottom surface of a cooking container and a manufacturing method thereof.
