그러나, 종래기술에 따른 조리용기는, 녹말 음식성분에 약하여 장시간 사용시 색채의 변화가 발생하고, 음식물 조리시 열과다로 인해 색채의 변색이 발생되는 문제점이 있었다.However, the cooking vessel according to the prior art, there is a problem that the color change occurs when used for a long time due to the weak food starch, and the color change due to excessive heat during food cooking.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 냄비나 후라이팬 등의 알루미늄 조리용기 내·외면에 다양한 무늬 및 모양의 색채가 나오도록 다중의 색소를 반복적으로 착색하여 전해피막처리함으로써, 색채에 의한 미려함을 나타낼 수 있고, 장시간 사용시에도 조리용기의 변색 및 탈색을 방지할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve the above problems, by repeatedly coloring a plurality of pigments so that the color of the various patterns and shapes on the inner and outer surfaces of the aluminum cooking vessel, such as pots or pans, by electrolytic coating treatment, color The purpose is to be able to exhibit a beautiful by, and to prevent the discoloration and discoloration of the cooking vessel even when used for a long time.

상기한 바와 같은 목적을 달성하기 위하여 안출된 본 발명의 알루미늄제 착색 조리용기의 제조방법에 의하면, 알루미늄 판재로 소정형상의 조리용기를 성형하는 성형공정과; 상기 성형공정에서 성형된 조리용기를 절삭 및 연마처리하여 불순물을 제거하는 크리닝공정과; 상기 크리닝공정에 의해 불순물이 제거된 조리용기의 내·외면에 소정형상의 특수테이프 부착 및 도료를 도포하여 전해피막처리하는 표면처리공정과; 상기 표면처리공정 후, 피막탱크에 임의의 색소를 혼합하고 조리용기를 넣어 착색과 함께 전해피막처리하는 과정을 반복 수행하는 혼합착색공정과; 상기 조리용기를 건조시키는 건조공정과; 상기 건조공정 후, 기타 부품을 결합하여 완성품을 만드는 조립공정을 포함하는 것을 특징으로 한다.According to the method for producing an aluminum colored cooking vessel of the present invention devised to achieve the above object, a molding step of molding a cooking vessel of a predetermined shape from an aluminum plate; A cleaning step of removing impurities by cutting and polishing the cooking vessel formed in the molding step; A surface treatment step of attaching a special tape of a predetermined shape and applying a coating material to the inner and outer surfaces of the cooking vessel from which impurities are removed by the cleaning process and electrolytic coating; After the surface treatment step, the mixing color process of repeating the process of mixing an arbitrary pigment in the coating tank and putting the cooking vessel and the electrolytic coating treatment with the coloring; A drying step of drying the cooking vessel; After the drying step, it is characterized in that it comprises an assembly step of making a finished product by combining the other parts.

이하, 본 발명의 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는, 본 발명에 따른 조리용기의 제조공정도이고, 도 3은, 본 발명에 따른 조리용기를 나타낸 개략적인 사시도이다.2 is a manufacturing process diagram of the cooking vessel according to the present invention, Figure 3 is a schematic perspective view showing a cooking vessel according to the present invention.

본 발명에 따른 조리용기는, 도 2 및 도 3에 도시된 바와 같이, 성형공정, 크리닝공정, 표면처리공정, 전해피막처리공정, 혼합착색공정, 건조공정 및 조립공정의 순서를 거치면서 제조된다.2 and 3, the cooking vessel according to the present invention is manufactured by going through a molding process, a cleaning process, a surface treatment process, an electrolytic coating process, a mixed coloring process, a drying process, and an assembly process. .

이하, 본 발명에 따른 알루미늄제 착색 조리용기의 제조방법을 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, a method for manufacturing an aluminum colored cooking container according to the present invention will be described with reference to FIG. 2.

먼저, 알루미늄과 같은 판재를 준비한 다음, 상기 판재를 소정형상을 갖는 조리용기(10)로 성형하는 성형공정을 행한다. First, a plate such as aluminum is prepared, and then a molding step of molding the plate into a cooking vessel 10 having a predetermined shape is performed.

이어서, 상기와 같이 성형된 조리용기(10)가 잘 코팅되도록 하기 위해 절삭 및 연마처리하여 불순물을 제거하는 크리닝공정을 행한다. Subsequently, a cleaning process of removing impurities by cutting and polishing is performed to ensure that the cooking vessel 10 formed as described above is well coated.

그리고, 상기 크리닝공정에 의해 불순물이 제거된 조리용기(10) 내·외면(11, 12)에 소정형상의 무늬 및 모양을 갖는 특수테이프(20)를 부착하거나 도료를 도포한 다음, 피막탱크에 넣어 전기를 통전시키고 경질피막을 입히는 전해피막처리를 함으로써 표면처리공정을 행한다. 이때, 상기 표면처리공정을 거친 조리용기(10)는 내·외면(11, 12)이 검정색으로 변하게 되고, 도료가 도포된 부위 및 특수테이프(20)를 제거하면 알루미늄 원색이 남게되어 이중 색채로 구분이 된다.Then, by attaching a special tape 20 having a predetermined pattern and shape or applying paint to the inner and outer surfaces 11 and 12 of the cooking vessel 10 from which impurities are removed by the cleaning process, and then coating the coating tank. The surface treatment step is carried out by electrolytic coating treatment to apply electricity and apply a hard coating. At this time, the cooking vessel 10, which has undergone the surface treatment process, turns the inner and outer surfaces 11 and 12 to black, and when the portions to which the paint is applied and the special tape 20 are removed, the primary colors of aluminum remain, resulting in dual colors. It is distinguished.

그 다음, 상기 조리용기(10)의 원색으로 남은 부위에 색채를 내기 위해 피막탱크에 임의의 색소를 혼합하고, 상기 피막탱크에 조리용기(10)를 넣어 착색과 함께 전해피막처리하는 과정을 반복 수행하는 혼합착색공정을 행한다. 이에 의해, 상기 조리용기는 검정색 부분 및 특수테이프(20) 제거에 의한 알루미늄 원색 부분이 각기 다른 색채로 변화되어 혼합 색채를 이루게 된다.Then, to color the portion remaining as the primary color of the cooking vessel 10, a mixture of arbitrary pigments in the coating tank, and put the cooking vessel 10 in the coating tank to repeat the process of electrolytic coating treatment with the coloring. A mixed coloring process is performed. As a result, the cooking vessel is changed to a different color of the primary color of the aluminum by removing the black portion and the special tape 20 to form a mixed color.

일 예로, 금색의 색소를 피막탱크에 넣어 전해피막처리를 할 경우, 상기 조 리용기(10)의 검정색 부분은 쵸코렛색으로 되고, 알루미늄 원색 부분은 금색으로 남게된다. 즉, 상기 조리용기(10)의 몸체는 반복 수행이 가능한 혼합착색공정에 의해 그 색상과 무늬를 임의로 조절할 수 있을 뿐만 아니라, 여러가지 다양한 색체를 나타낼 수 있다.For example, when the gold pigment is put into the coating tank for the electrolytic coating treatment, the black portion of the cooking container 10 becomes chocolate color, and the aluminum primary color portion remains gold. That is, the body of the cooking vessel 10 can not only arbitrarily adjust its color and pattern by the mixed coloring process that can be repeatedly performed, it can represent a variety of different colors.

더욱이, 상기 조리용기(10)의 상부에 안착되는 뚜껑도, 상기와 같은 제조방법에 의해 다중의 색채를 나타낼 수 있다.In addition, the lid seated on the upper portion of the cooking vessel 10 may also exhibit a plurality of colors by the manufacturing method as described above.

상기 혼합착색공정을 거친 조리용기(10)는, 건조공정을 거친 후, 기타 부품을 결합하여 완성품을 만드는 조립공정에 의해 제작이 완료된다.After the mixing and coloring process, the cooking vessel 10, after the drying process, the production is completed by the assembling process to combine the other parts to make a finished product.

이상에서는 본 발명의 바람직한 실시예를 설명하였으나, 본 발명의 범위는 이같은 특정 실시예에만 한정되지 않으며, 해당분야에서 통상의 지식을 가진자라면 본 발명의 특허청구범위내에 기재된 범주내에서 적절하게 변경이 가능할 것이다.Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and those skilled in the art may appropriately change within the scope described in the claims of the present invention. This will be possible.

이상에서 설명한 바와 같이 본 발명에 따른 알루미늄제 착색 조리용기의 제조방법에 의하면, 냄비나 후라이팬 등의 알루미늄 조리용기 내·외면에 다양한 무늬 및 모양의 색채가 나오도록 다중의 색소를 반복적으로 착색하여 전해피막처리함으로써, 색채에 의한 미려함을 나타낼 수 있고, 장시간 사용시에도 조리용기의 변색 및 탈색을 방지할 수 있는 효과가 있다.As described above, according to the method for manufacturing an aluminum colored cooking container according to the present invention, a plurality of pigments are repeatedly colored so that colors of various patterns and shapes appear on the inner and outer surfaces of an aluminum cooking container such as a pot or a frying pan. By the electrolytic coating treatment, it is possible to show the beauty of the color and to prevent the discoloration and discoloration of the cooking vessel even when used for a long time.
