Description

ＩＨ 조리용기의 제조방법 {Manufacturing Method for Induction Heating Cooker}IH cooking container manufacturing method {Manufacturing Method for Induction Heating Cooker}

본 발명은 유도가열 방식을 이용하여 음식물을 조리하는 IH 조리용기를 제조하는 방법에 관한 것으로서, 더욱 상세하게는, 조리면에 요철부가 구비된 조리용기를 제조할 때에, 요철부의 성형과 IH 판의 고정을 동시에 수행하여, 공정을 단순화하고 제조시간과 제조비용을 줄일 수 있도록 한, IH 조리용기의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing an IH cooking container for cooking food using an induction heating method, and more particularly, when manufacturing a cooking container having an uneven portion on a cooking surface, the molding of the uneven portion and the IH plate It relates to a method for manufacturing an IH cooking container, which can be fixed at the same time to simplify the process and reduce manufacturing time and manufacturing cost.

일반적으로, 인덕션 렌지(Induction Range)는, 전원을 공급받아 고전압이 인가되어 자장을 발생하기 위한 코일이 내장되어 있으며, 이러한 인덕션 렌지는 코일에 고전압이 인가되면 자장이 유도되고, 이 자장이 미치는 영역에 있는 금속체가 가열되는 원리를 이용한 가열장치를 말한다.In general, an induction range has a built-in coil for generating a magnetic field when a high voltage is applied by receiving power. It refers to a heating device that uses the principle of heating a metal body in

인덕션 렌지는, 불꽃이나 유해가스 등이 발생하지 않기 때문에 화재의 위험성이 없으며, 가스를 열원으로 사용하는 경우에 필연적으로 발생하는 일산화탄소 등의 유해가스를 방지할 수 있고, 실내 산소의 소모가 적어 쾌적한 실내를 유지할 수 있는 장점이 있다. 또한, 인덕션 렌지는, 용기를 가열하는 도중에, 그릴에 손이 닿아도 화상의 우려가 없으며, 불꽃이 없기 때문에 화재 및 폭발의 위험성이 없으며, 전원이 공급된 상태에서 그릴에 신체부위가 접촉되어도 화상을 입지 않는 장점을 지니고 있어, 최근 많이 사용되고 있다.Since the induction stove does not generate flames or harmful gases, there is no risk of fire, it can prevent harmful gases such as carbon monoxide that are inevitably generated when gas is used as a heat source, and the consumption of oxygen in the room is small, so it is comfortable It has the advantage of being able to keep it indoors. In addition, the induction stove does not have a risk of burns even if a hand touches the grill while heating the container, there is no risk of fire or explosion because there is no flame, and even if a body part comes into contact with the grill while power is supplied, there is no risk of burns. It has the advantage of not wearing clothes, so it has been used a lot recently.

한편, 인덕션 렌지에서는, 고전압에 의해 발생하는 자장과의 자기감응이 가능한 금속 재질로 이루어진 조리용기만 사용할 수 있고, 조리용기의 대부분을 차지하는 알루미늄과 같은 비철금속으로 이루어진 조리용기나, 석기 및 도자기류의 조리용기는 사용할 수 없다. 이에 따라, 인덕션 렌지에서 사용할 조리용기는, 비철금속으로 이루어진 용기본체의 바닥면에, 철 성분을 함유한 금속판(이하 'IH 판'이라 한다)을 부착하고 있다.On the other hand, in the induction range, only a cooking vessel made of a metal material capable of magnetic sensitivity with a magnetic field generated by a high voltage can be used, and a cooking vessel made of a non-ferrous metal such as aluminum, which occupies most of the cooking vessel, or stoneware and ceramics. Cooking utensils cannot be used. Accordingly, the cooking vessel to be used in the induction range is attached to a metal plate (hereinafter referred to as an 'IH plate') containing iron on the bottom surface of the container body made of non-ferrous metal.

다시 말해, IH 조리용기는 비철금속과 철계 금속의 이종 재질의 접합에 의해 제작되고 있다.In other words, the IH cooking vessel is manufactured by bonding different materials of a non-ferrous metal and a ferrous metal.

IH 조리용기의 제조 시, 이종 재질의 접합 방식으로는 용접 방식이 보편적이며, 제품의 대량생산이 가능한 다이캐스팅 방식은 적용하기 어렵다. 다이캐스팅 방식으로 조리용기를 생산할 경우, 이종 재질의 용기본체와 IH 판을 일체화하기가 곤란할 뿐 아니라 일체화 후에도 일정 시간이 지나면 IH 판이 떨어지는 문제가 있다.When manufacturing IH cooking containers, welding is a common method of joining different materials, and it is difficult to apply the die-casting method that enables mass production of products. When a cooking container is produced by a die-casting method, it is difficult to integrate the container body and the IH plate of different materials, and there is a problem that the IH plate falls off after a certain period of time after integration.

한편, IH 조리용기를 제조하는 종래의 방법은, 도 1에 도시된 바와 같이, 알루미늄계 소재를 이용하여 조리용기를 제조하는 단계와; 조리용기의 하부에 부착되는 IH 판을 제조하는 단계와; 조리용기의 저면에 IH 판을 압착하여 고정하는 단계와; 조리용기의 외부면을 도색하고 내부면을 테프론 코팅한 후 손잡이 등을 부착하여 제품을 완성하는 마무리 단계를 포함하고 있다.On the other hand, a conventional method of manufacturing an IH cooking vessel, as shown in FIG. 1, comprises the steps of manufacturing a cooking vessel using an aluminum-based material; manufacturing an IH plate attached to the lower portion of the cooking vessel; The step of pressing and fixing the IH plate to the bottom of the cooking vessel; It includes a finishing step of painting the outer surface of the cooking container, coating the inner surface with Teflon, and attaching a handle to complete the product.

그런데 최근 들어, 조리면에 요철부가 형성된 조리용기가 출시되고 있다. 조리용기의 조리면에 요철부를 형성하는 방법으로서, 알루미늄계 소재를 성형하여 조리용기를 제작할 때에 요철부가 동시에 형성되도록 하는 방식 혹은 조리용기의 제작이 완료된 후에 조리면을 가압하여 성형하는 방식이 현재까지 사용되어 왔다. 하지만, 조리용기의 제작시에 요철부를 함께 형성하게 되면, 복잡한 요철부의 구조로 인해, 제작된 조리용기가 금형으로부터 이탈되지 않거나, 이탈 과정에서 요철부가 손상되는 문제가 발생한다.However, recently, a cooking vessel having an uneven portion formed on a cooking surface has been released. As a method of forming the concave-convex portion on the cooking surface of the cooking vessel, a method of forming the concave-convex portion at the same time when manufacturing the cooking vessel by molding an aluminum-based material or a method of forming the cooking surface by pressing the cooking surface after the manufacturing of the cooking vessel is completed has been used However, when the concave and convex portions are formed together during the manufacturing of the cooking vessel, there is a problem in that the manufactured cooking vessel is not separated from the mold or the concave and convex portions are damaged during the separation process due to the complicated structure of the concave and convex portions.

한편, 제작된 조리용기에 요철부를 가압 성형하는 후자의 경우는, 추가 공정으로 인해, 제조시간과 제조비용이 증가하는 문제가 발생한다.On the other hand, in the case of the latter, in which the concave-convex part is press-molded on the manufactured cooking container, there is a problem in that the manufacturing time and manufacturing cost increase due to the additional process.

또한, IH 조리용기의 조리면에 요철부를 형성하는 경우에, IH 판을 압착하는 공정과, 조리면에 요철부를 형성하는 공정을 별도로 수행해야 함에 따라, 제조시간과 제조비용이 증가하는 문제가 생긴다.In addition, when the concave-convex portion is formed on the cooking surface of the IH cooking container, the process of pressing the IH plate and the process of forming the concave-convex portion on the cooking surface must be separately performed, which increases the manufacturing time and manufacturing cost. .

특허문헌 3은, 조리용기의 바닥면에 음각부를 함몰 형성하여 음식물과 조리용기의 바닥면과의 접촉면적을 줄여, 음식물이 조리용기의 바닥면에 눌어붙는 것을 방지할 수 있도록 함과 아울러, 두 번의 코팅공정을 거쳐 음식물의 눌어붙음을 방지하면서도 코팅층의 벗겨짐을 효과적으로 방지할 수 있는 조리용기의 제조방법을 개시하고 있다.Patent Document 3 discloses that an intaglio is formed in the bottom surface of the cooking vessel to reduce the contact area between the food and the bottom surface of the cooking vessel, thereby preventing the food from sticking to the bottom surface of the cooking vessel. Disclosed is a method for manufacturing a cooking container capable of effectively preventing the coating layer from peeling off while preventing food from sticking through the coating process.
