Description

전자유도가열식 조리기구의 접합장치{Junction device of electron induction heating type cooker}Junction device of electron induction heating type cooker

본 발명은 전자유도가열식 조리기구의 접합장치에 관한 것으로서, 상세하게는 접합을 위한 작업공정을 줄이면서 보다 견고히 접합될 수 있도록 한 것이다.The present invention relates to a bonding apparatus for an electromagnetic induction heating cooker, and in particular, to be more firmly bonded while reducing the work process for bonding.

전자유도가열식 조리기구는 경량이면서 열효율이 우수하고 또 디자인을 다양화할 수가 있는 알루미늄합금제 본체 외면에 자성을 띠는 금속제 발열판을 접합형성하여서 된 것으로서, 크게 발열판이 안치된 몰드 내에 알루미늄 용탕을 주입하여 가압후 탈형하는 주물타입과, 1차성형된 알루미늄 본체 저면에 발열판을 압입고정하는 시트타입으로 접합토록 하고 있다.The electromagnetic induction cooker is formed by bonding a magnetic metal heating plate to the outer surface of the aluminum alloy body, which is lightweight, has excellent thermal efficiency and can diversify the design. It is to be joined to the casting type which is demolded after pressing and the sheet type which press-fits the heating plate to the bottom of the primary molded aluminum body.

그러나 주물타입은 발열판과의 접합은 견고하게 이루어질 수가 있다 하겠으나 접합을 견고하게 하기 위한 돌기를 형성해 주어야 하고 특히 알루미늄 용탕이 응고되기까지 시간이 많이 소요되어 현저한 생산성 저하를 가져오게 된다.However, the casting type can be firmly bonded to the heating plate, but it is necessary to form protrusions to solidify the bonding, and in particular, it takes a long time until the molten aluminum is solidified, resulting in a significant decrease in productivity.

따라서 이제껏 거의 대부분 시트타입으로 제작되고 있으나 시트타입 역시 주물타입에 비해 우수할 뿐 많은 결점들이 지적되고 있다.Therefore, most of the sheet type ever produced, but the sheet type is also superior to the casting type, many drawbacks are pointed out.

시트타입의 대표적인 선행기술로서는 일본 특개평10-127491호를 예로 들 수가 있으며, 이는 발열판 상면에 쐐기형 돌기를 촘촘히 돌출형성하여 그 위에 기 성형된 본체를 얹고 프레싱하게 되면 쐐기형 돌기가 본체 저부로부터 깊숙히 파고 들어 서로 일체감있게 접합되도록 한 것이다.As a representative prior art of sheet type, Japanese Patent Application Laid-open No. Hei 10-127491 can be exemplified, and this means that a wedge-shaped protrusion is formed on the upper surface of the heating plate so that a wedge-shaped protrusion is placed on the upper surface of the heating plate and pressed. Digging deeply into one to be united together.

따라서 발열판 상에 쐐기형 돌기를 촘촘히 형성해 주기 위한 까다로운 제조공정이 추가되므로 생산성저하를 가져오게 되고 또 쐐기형 돌기는 바닥면과 직각을 유지하지 못하거나 또는 강도약화시 압착과정에서 알루미늄제 본체 내부를 파고들지 못하고 쉽게 휘어져 해당부분은 접합이 이루어질 수가 없게 되며 쐐기형 돌기를 갖지 못한 테두리부는 본체와 단순한 접촉상태를 유지하게 되므로 조리시 본체와 가열판이 갖는 열팽창 갯수 차이로 박리현상이 급속히 진행되고 또 약한 충격에도 쉽게 박리되므로 사용수명이 짧은 등의 치명적인 결점을 지니고 있는 것이다.Therefore, a tricky manufacturing process for densely forming wedge-shaped protrusions on the heating plate is added, resulting in a decrease in productivity.Wedge-shaped protrusions do not maintain a right angle with the bottom surface, or the inside of the aluminum body in the pressing process when strength is weakened. It is not easy to dig and bends easily, so that the part cannot be joined and the edges without wedge-shaped protrusions are kept in simple contact with the main body, so the peeling phenomenon progresses rapidly and weakly due to the difference in the number of thermal expansions of the main body and the heating plate during cooking. Since it peels easily on impact, it has a fatal defect such as short service life.

이후 쐐기형 돌기를 이용한 접합시의 결점들을 해소하고자 통공이 촘촘히 형성된 발열판과 이역시 발열판의 통공과 일치되는 무수한 통공을 갖는 받침판을 겹쳐서 하부몰드 상에 안치시키고 그 위에 1차성형된 알루미늄 본체를 공급하여 가압하게 되면 알루미늄 본체의 일부가 발열판과 받침판이 갖는 통공 내부로 융기되어 받침판의 강제분리시 그 융기부가 발열판 저부로 일부돌출되게 하고 돌출된 융기부를 프레싱으로 압착하여 리벳이음형태로 본체와 발열판이 일체감있게 접합되도록 한 접합방법이 제공된 바 있다.Then, in order to solve the defects in the joining using the wedge-shaped protrusions, the heating plate having densely formed holes and the supporting plate having countless through holes coinciding with the holes of the heating plate are placed on the lower mold, and the primary molded aluminum body is supplied thereon. When pressurized, part of the aluminum body is raised inside the through hole of the heating plate and the support plate, and when the support plate is forcibly separated, the ridge part partially protrudes to the bottom of the heating plate, and the protruding ridge is pressed by pressing to form the main body and the heating plate in the form of riveted joints. There has been provided a joining method for joining in unison.

그러나 이 역시 매회 발열판과 받침판을 통공이 일치되게 일체감있게 연결해 주어야 하고 또 접합후에는 받침판을 분리시켜 주기 위한 작업공정이 추가되므로 생산성저하를 가져오게 되고 또 통공을 갖지 못한 발열판의 테두리부분은 접합이 제대로 이루어지지 못해 낮은 열전도율로 열효율이 떨어지게 되는 등의 결점들을 지니게 되는 것이다.However, this also needs to connect the heating plate and the supporting plate to the unity in a consistent manner every time, and after joining, a work process for separating the supporting plate is added, which leads to a decrease in productivity. It is not done properly, and has low defects such as low thermal conductivity and low thermal efficiency.
