Description

전자 유도가열방식 조리기구용 자성체 금속판{Magnetic metal board for cooker of eletromagnetic induction heating method}Magnetic metal board for electromagnetic induction heating type cookware {Magnetic metal board for cooker of eletromagnetic induction heating method}

본 발명은 전자유도가열방식의 주방용 조리용기를 제작구성함에 있어서, 용기 본체의 바닥부 저면에 일체형으로 성형되는 자성체 금속판의 개량에 관한 것이다.The present invention relates to the improvement of the magnetic metal plate integrally molded on the bottom surface of the bottom of the container body in the production of the electromagnetic induction heating kitchen cooking vessel.

일반적으로 전자유도가열방식의 주방용 조리용기의 바닥부 저면에는 자성체금속판이 일체형으로 성형되어 있다.In general, a magnetic metal plate is integrally formed on the bottom of the bottom of an electromagnetic induction heating kitchen cooking vessel.

그러나 기사용되고 있는 자성체 금속판은 부착성이 양호하지 못하여 사용중 용기본체 바닥부로부터 박리되는 현상이 발생하게 될 뿐 아니라 발열에 의해 휘어지게 되므로 열효율이 떨어지게 되는 단점이 있다.However, the magnetic metal plate being used for the article has a disadvantage in that the adhesiveness is not good and the peeling off from the bottom of the container body during use is not only caused, but also bends due to heat generation, thereby reducing thermal efficiency.

또한 자성체 금속판의 두께가 얇거나 두꺼워 다음과 같은 문제를 야기케 한다.In addition, the thickness of the magnetic metal plate is thin or thick, causing the following problems.

즉 자성체 금속판의 두께가 얇은 경우에는 평판도가 떨어질 뿐 아니라 부착성이 없어 사용중 쉽게 박리되며, 가열시 열효율이 떨어지게 되는 문제가 있고, 두꺼울 경우에는 가공시 경제성이 없을 뿐 아니라 가공이 어렵게 되는 등의 단점이 있는 것이었다.In other words, when the thickness of the magnetic metal plate is thin, not only the flatness is lowered but also the adhesiveness is easily peeled off during use, and there is a problem in that the thermal efficiency is lowered during heating. This was to be.

본 발명은 이러한 종래의 제반 단점을 시정하고자 용기 본체 바닥 저면에 자성체 금속판(SUS 430)이 일체로 성형되게 하는 전자유도가열방식의 조리용기를 구성함에 있어서, 제품의 사용시 자성체 금속판의 변형을 방지하여 평면성을 유지케 함과 동시에 열효율 및 부착력을 증진케 하며 또한 자성체 금속판의 두께를 가장 이상적인 두께로 하여 용이한 가공성과 열효율 및 부착성이 양호하도록 한 이상적인 자성체 금속판을 제공할 수 있도록 한 것이다.The present invention is to configure the electromagnetic induction heating cooking vessel to be formed in a magnetic metal plate (SUS 430) integrally on the bottom surface of the container body to correct the above-mentioned disadvantages, to prevent the deformation of the magnetic metal plate when using the product It is intended to provide an ideal magnetic metal plate that maintains planarity and improves thermal efficiency and adhesion, and also makes the thickness of the magnetic metal plate the most ideal thickness for easy processing and good thermal efficiency and adhesion.

상기 목적을 달성하기 위하여 본 발명은 전자유도가열방식의 조리용기제작을 위한 자성체 금속판을 구성함에 있어서, 금속판의 중앙에 적절한 크기를 갖는 완충공을 뚫어 제품의 발열시 휨현상없이 평면성을 유지케 하고, 또한 자성체 금속판의열효율 및 부착성증진을 위하여 금속판에 뚫려지는 통공의 면적(완충공 포함)을 전체면적의 20~40% 범위로 한다.In order to achieve the above object, the present invention, in the construction of a magnetic metal plate for the production of the electromagnetic induction heating type cooking vessel, by drilling a buffer hole having a suitable size in the center of the metal plate to maintain the flatness without the phenomenon of warping during heating of the product, In addition, the area of the through hole (including the buffer hole) drilled through the metal plate is in the range of 20 to 40% of the total area for improving the thermal efficiency and adhesion of the magnetic metal plate.

상기에서 부착성의 증진을 위한 수단으로서는 자성체 금속판을 불산용액으로 처리하여 외면에 부식처리되게 하므로서 보다 양호한 부착수단을 제공할 수 있게 되며 사용되는 자성체 금속판의 두께는 0.5~1mm 정도로 하여서 된 것이다.As a means for promoting adhesion in the above it is possible to provide a better attachment means by treating the magnetic metal plate with a hydrofluoric acid solution to the outer surface and the thickness of the magnetic metal plate used is about 0.5 ~ 1mm.

이하 본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에서 제공하고자 하는 자성체 금속판(SUS 430)(10)의 평면도이고, 도 2를 측면구성도로서 본 발명은 자성체 금속판(10)의 두께(T)를 0.5~1.0mm 정도인 자성체 판재를 원형으로 가공하여 사용한다.1 is a plan view of a magnetic metal plate (SUS 430) (10) to be provided in the present invention, Figure 2 as a side configuration of the present invention is a magnetic material having a thickness (T) of the magnetic metal plate 10 of about 0.5 ~ 1.0mm The plate is processed into a circle and used.

실험한 바에 의하면 자성체 금속판(10)의 두께(T)가 0.5mm이하인 경우에는 두께가 너무 얇아 가공시 평판도가 현저히 떨어질 뿐 아니라 가열시 열효율이 떨어지고 또한 부착성이 없어 사용중 쉽게 박리된다.According to the experiment, when the thickness (T) of the magnetic metal plate 10 is 0.5 mm or less, the thickness is so thin that not only the flatness is remarkably degraded during processing, but also the heat efficiency during heating is low and there is no adhesiveness, so it is easily peeled off during use.

반대로 1mm이상인 경우에는 열효율면에서는 큰 차이가 없으나 가공성이 떨어지게 되므로 생산성 증대효과를 기대할 수가 없고 또한 재료낭비를 초래하게 되므로 경제적이지 못하기 때문에 이상적인 두께는 0.5~1mm정도인 것이 바람직하다.On the contrary, in the case of 1mm or more, there is no big difference in terms of thermal efficiency, but since the workability is reduced, the productivity increase effect cannot be expected, and since it causes material waste, it is preferable that the ideal thickness is about 0.5 to 1mm.

자성체 금속판(10)의 중앙에는 완충공(20)을 구성한다.A buffer hole 20 is formed in the center of the magnetic metal plate 10.

상기 완충공(20)은 용기 본체(30)의 바닥부(31) 저면에 자성체 금속판(10)이 일체로 성형된 상태에서 사용시 열팽창에 따른 변형을 방지하기 위한 것이다.The buffer hole 20 is for preventing deformation due to thermal expansion when the magnetic metal plate 10 is integrally formed on the bottom surface 31 of the bottom of the container body 30.

다시 설명하면 자성체 금속판(10)의 중앙에 뚫린 완충공(20)을 기준으로 하여 각 방향으로 서로 분리되게하므로 열팽창에 따른 변형정도를 분산시키게 되고 따라서 그만큼 열팽창에 따른 변형을 방지할 수 있게 된다.In other words, since they are separated from each other in each direction on the basis of the buffer hole 20 drilled in the center of the magnetic metal plate 10, the degree of deformation due to thermal expansion is dispersed and thus the deformation due to thermal expansion can be prevented.

상기에서 완충공(20)은 크면 클수록 완충의 효과는 증진되나 열효율면에서 떨어지게 되므로 한정할 필요성이 있다.In the above, the larger the buffer hole 20, the larger the buffering effect is enhanced, but in terms of thermal efficiency, there is a need to limit.

다시 설명하면 자성체 금속판(10)의 직경(L)에 대하여 완충공(20)의 직경(ℓ)이 약16~33% 정도로 하는 것이 바람직하다.In other words, the diameter L of the buffer hole 20 is preferably about 16 to 33% of the diameter L of the magnetic metal plate 10.

예를 들면 자성체 금속판(10)의 직경(L)이 200mm일 경우에는 완충공(20)의 직경(ℓ)이 약50mm인 것이 바람직하고, 또한 자성체 금속판(10)의 직경(L)이 120mm일 경우에는 완충공(20)의 직경(ℓ)이 20mm정도가 적합하다.For example, when the diameter L of the magnetic metal plate 10 is 200 mm, the diameter L of the buffer hole 20 is preferably about 50 mm, and the diameter L of the magnetic metal plate 10 is 120 mm. In this case, the diameter L of the buffer hole 20 is suitably about 20 mm.

상기에서 자성체 금속판(10)의 직경(L)이 200mm이상되더라도 완충공(20)이 직경은 50mm이상 확장할 수는 없으며, 그 이유는 완충공(20)의 직경이 50mm이상일 경우에는 열효율면에서 떨어지기 때문에 사용이 곤란하다.Even if the diameter L of the magnetic metal plate 10 is 200 mm or more, the diameter of the buffer hole 20 cannot be expanded by more than 50 mm, and the reason is that when the diameter of the buffer hole 20 is 50 mm or more, in terms of thermal efficiency. Difficult to use because it falls.

또한 완충공(20)의 직경이 20mm이하일 경우에는 완충작용이 떨어지기때문에 역시 사용이 곤란하다.In addition, when the diameter of the buffer hole 20 is 20mm or less, it is difficult to use because the buffer action is reduced.

또한 자성체 금속판(10)에는 등간격으로 다수개의 통공(21)을 뚫어 구성하므로서 부착성을 증진케 할 뿐 아니라 열팽창에 따른 변형을 좀더 줄일 수 있게 된다.In addition, the magnetic metal plate 10 is formed by drilling a plurality of through-holes 21 at equal intervals, thereby improving adhesion and further reducing deformation due to thermal expansion.

이때 자성체 금속판(10)에 뚫려지는 통공(21)의 정도는 자성체 금속판(10)의 전체면적(완충공 포함)을 100%으로 하였을 때 20~40%(완충공 포함)정도로 하는 것이 부착성과 열효율, 평면성 및 가공성이 우수한 것으로 측정되었다.At this time, the degree of the through-hole 21 drilled in the magnetic metal plate 10 is about 20-40% (including the buffer hole) when the total area (including the buffer hole) of the magnetic metal plate 10 is 100%. It was measured to be excellent in planarity and workability.

상기에서 통공(21) 및 완충공(20)의 면적이 전체면적의 20%미만일 경우에는 용기 본체(30) 바닥부(31)와의 부착성이 떨어지게 되므로 사용중 박리될 우려가 있고, 또한 열팽창에 의해 휨현상이 발생하게 될 우려가 높다.When the area of the through-hole 21 and the buffer hole 20 is less than 20% of the total area in the above, the adhesion to the bottom portion 31 of the container body 30 is inferior, which may cause peeling during use, and also due to thermal expansion. There is a high possibility that warpage will occur.

또한 통공(21) 및 완충공(20)의 면적이 전체면적의 40% 이상일 경우에는 열효율이 떨어지고 가공시 평면성이 떨어지게 되므로 바람직하지 않다.In addition, when the area of the through hole 21 and the buffer hole 20 is 40% or more of the total area, the thermal efficiency is lowered and the planarity during processing is not preferable.

본 발명의 자성체 금속판(10)을 구성함에 있어서, 더욱 효과적인 부착성을 부여하기 위하여 불산용액에 처리하여 표면이 부식되게 하면 자성체 금속판(10)의 표면적을 증진시켜 접착력을 향상시킬 수 있게 된다.In constructing the magnetic metal plate 10 of the present invention, if the surface is corroded by treating with a hydrofluoric acid solution in order to give more effective adhesion, the surface area of the magnetic metal plate 10 can be enhanced to improve adhesion.

또한 자성체 금속판(10)에 뚫려지는 통공(21)은 원형의 수직관통공인 것이 가공성이 용이하다.In addition, the through hole 21 to be drilled in the magnetic metal plate 10 is a circular vertical through hole is easy to process.

미설명부호 (40)은 요철부이다.Reference numeral 40 is an uneven part.

이와 같이 구성된 본 발명은 도 3에서와 같이 주방용기본체(30)의 바닥부(31) 저면에 자성체 금속판(10)이 일체로 성형되게 한 다음 자성체 금속판(10)의 발열에 의해 조리가 이루어지게 된다는 것은 종래와 같으나 본 발명에서 제공하고자 하는 자성체 금속판(10)은 다음과 같은 차이가 있다.The present invention configured as described above allows the magnetic metal plate 10 to be integrally molded on the bottom surface 31 of the bottom of the kitchen main body 30 as shown in FIG. 3 and then cooked by heating of the magnetic metal plate 10. It is the same as the conventional but the magnetic metal plate 10 to be provided in the present invention has the following differences.

즉 자성체 금속판(10)의 두께(T)를 0.5~1mm로 하여 작업성과 열효율, 경제성 및 부착성을 증진케 할 뿐 아니라 자성체 금속판(10)의 중앙에 완충공(20)을 뚫어 열팽창에 의한 변형을 방지하여 평면성을 유지케 하므로서 열효율을 증진시킬 수 있다.That is, the thickness T of the magnetic metal plate 10 is 0.5 to 1 mm, thereby improving workability, thermal efficiency, economy and adhesion, as well as drilling the buffer hole 20 in the center of the magnetic metal plate 10 to deform by thermal expansion. By maintaining the planarity to prevent the heat efficiency can be improved.

또한 자성체 금속판(10)에 구성되는 통공(21)과 완충공(20)의 면적을 자성체금속판(10) 면적에 대하여 20~40% 정도로 한정하여 사용중 박리현상을 방지케 하고 또한 평면성을 유지케 하여 열효율을 좋게 함과 동시에 가공성을 용이하게 할 수 있게 된다.In addition, the area of the through hole 21 and the buffer hole 20 included in the magnetic metal plate 10 is limited to about 20 to 40% of the magnetic metal plate 10 area to prevent peeling during use and to maintain flatness. The thermal efficiency can be improved and the workability can be facilitated.

또한 자성체 금속판(10) 중앙에는 완충공(20)이 뚫려져 있어 열팽창에 따른 완충역할을 하게 되므로 사용중 휨현상을 방지할 수 있게 된다.In addition, since the buffer hole 20 is drilled in the center of the magnetic metal plate 10 to play a buffer role due to thermal expansion, it is possible to prevent bending during use.

상기 완충공(20)은 자성체 금속판(10)의 직경(L)에 대하여 약16~33%정도의 직경(ℓ)으로 구성되어 있어 자성체 금속판(10)의 발열효율에는 별다른 문제가 없다.The buffer hole 20 is composed of a diameter (L) of about 16 to 33% of the diameter (L) of the magnetic metal plate 10, there is no problem in the heat generation efficiency of the magnetic metal plate 10.

또한 자성체 금속판(10)은 불산용액으로 부식처리되어 있어 용기 본체(30) 바닥부 저면에 일체형으로 성형될 때 더욱 견고하고 완벽한 접착성을 기대할 수 있게 된다.In addition, since the magnetic metal plate 10 is corroded with hydrofluoric acid solution, when the molded body is integrally formed on the bottom surface of the bottom of the container body 30, more robust and perfect adhesiveness can be expected.

이상 설명한 바와 같이 본 발명은 전자유도가열방식의 조리용기에 적용되는 자성체의 금속판을 구성함에 있어서, 자성체 금속판의 두께와 완충공 및 통공의 크기 및 면적을 가장 이상적인 조건으로 한정하여 자성체 금속판을 구성사용케 하므로서 열효율이 우수할 뿐 아니라 견고한 접착력을 유지케 하며 또한 가공성과 생산성 및 사용중 열팽창에 의한 변형을 방지케 하여 보다 이상적인 상태의 자성체 금속판을 제공할 수가 있게 되는 등의 효과가 있는 것이다.As described above, the present invention constitutes a magnetic metal plate by limiting the thickness of the magnetic metal plate, the size and the area of the buffer hole and the through hole to the ideal conditions in constructing the magnetic plate applied to the cooking container of the electromagnetic induction heating method. In addition, it is possible to provide a magnetic metal plate in an ideal state by not only excellent thermal efficiency but also maintaining a strong adhesive strength and preventing deformation due to workability and productivity and thermal expansion during use.
