유도가열용기의 바닥면 구조 및 이의 제조 방법 {Structure of bottom the induction heater cooker and its forming method} Structure of bottom the induction heater cooker and its forming method

본 발명은 유도가열기구에 올려져 유도열을 통해 음식물을 조리하는 유도가열용기에 관한 것으로, 특히 유도가열용기의 바닥면을 삼중으로 구성하도록 한 유도가열용기의 바닥면 구조 및 이의 제조 방법에 관한 것이다.The present invention relates to an induction heating vessel mounted on an induction heating apparatus to cook food through induction heating, and more particularly, to a bottom structure of an induction heating vessel configured to triple the bottom surface of the induction heating vessel, and a manufacturing method thereof. will be.

일반적으로, 유도가열기구는 코일에 흐르는 유도전류를 이용하여 에너지 효율을 극대화시키는 히팅기구로서, 이 유도가열기구는 전류의 흐름방향에 수직으로 자계를 형성시키는 가열기와, 이 가열기의 상부측에 구비되는 세라믹판 및, 이 세라믹판에 놓여지는 자성체인 조리용기로 구성된다.In general, an induction heating mechanism is a heating mechanism for maximizing energy efficiency by using an induction current flowing in a coil, and the induction heating mechanism is provided with a heater for forming a magnetic field perpendicular to the flow direction of the current, and is provided on the upper side of the heater. And a cooking vessel which is a magnetic substance placed on the ceramic plate.

여기서, 유도가열용기는 용기의 본체를 열전도성이나 성형성이 우수하면서도 비중이 비교적 낮은 알루미늄 또는 알루미늄합금 재질로 성형하여 무게를 최소화한 상태에서, 그 용기본체의 바닥면에 자성을 띠는 금속가열판을 압착 또는 접합과정을 통해 부착하여 외관을 성형하는 것이다. Here, the induction heating vessel is formed of aluminum or aluminum alloy material with excellent thermal conductivity or moldability and relatively low specific gravity, and thus minimizes weight. The metal heating plate has magnetic properties on the bottom surface of the container body. It is to form the appearance by attaching through a compression or bonding process.

그런데, 유도가열용기의 용기본체에 자성체인 철판 또는 스테인리스스틸판 또는 알루미늄합금판을 압착 또는 접합시키는 방법이 제안된 바 있지만, 이 용기는 용기바닥면의 평탄도가 일정하게 유지되지 못하고 열변형되는 경우 용기의 바닥면 중심부가 솟아올라 변형되는 문제점이 있었다. By the way, a method of crimping or bonding a magnetic plate, a stainless steel plate, or an aluminum alloy plate to a container body of an induction heating container has been proposed, but the flatness of the bottom of the container is not maintained at a constant flatness of the container and is thermally deformed. In this case, there is a problem in that the bottom surface of the container is raised and deformed.

따라서, 유도가열용기는 스테인리스스틸을 이용하여 본체와 보강판을 형성하고, 그 바닥면에는 열전도율을 높이기 위하여 열전달판으로서 알루미늄판을 개재함으로써, 유도가열용기의 바닥면이 평탄하지 못하여 균일하게 가열되지 못하는 단점을 해소한 다중 유도가열용기가 개발되었다.Therefore, the induction heating vessel forms a body and a reinforcement plate using stainless steel, and the bottom surface of the induction heating vessel is not evenly heated by interposing an aluminum plate as a heat transfer plate to increase the thermal conductivity on the bottom surface thereof. Multiple induction heating vessels have been developed to overcome the disadvantages.

즉, 유도가열용기의 용기본체에 자성체인 철판이나 스테인리스스틸판이나 알루미늄합금판 등을 다중으로 접합하는 방법이 제안된 바 있다.That is, a method of joining a plurality of magnetic plates, stainless steel plates, aluminum alloy plates, or the like to a container body of an induction heating container has been proposed.

더욱이, 다중 유도가열용기는 바닥 내부에 열전달판이 구비되었는지를 쉽게 육안으로 확인할 수 없기 때문에 불량품이 발생할 수 있음은 물론 이로 인해 소비자들에서 신뢰감을 줄 수 없을 뿐만 아니라 열전달판에 습기가 차는 경우 분리되거나 열전달 효율이 저하되는 문제점이 있었다.Moreover, the multiple induction heating vessels can not easily check whether the heat transfer plate is provided inside the floor, which may result in defective products, and this may not give the consumer confidence, and if the heat transfer plate gets wet, There was a problem that the heat transfer efficiency is lowered.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 조리용기의 접합구조를 변경하여 열전달판의 떨어짐을 방지함은 물론 유지보수비용을 절감할 수 있도록 한 유도가열용기의 바닥면 구조 및 이의 제조 방법을 제공하는 데에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, by changing the bonding structure of the cooking vessel to prevent the fall of the heat transfer plate, as well as to reduce the maintenance cost of the bottom of the induction heating vessel It is an object to provide a cotton structure and a method for producing the same.
