본 발명은 취사용기 제조방법에 관한 것으로, 특히 석재용기의 외측에 알루미늄합금이 주조되어 일반조리 및 전기압력솥의 내측용기로도 사용가능한 취사용기 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a cooker, in particular an aluminum alloy is cast on the outside of the stone container and relates to a method of manufacturing a cooker that can be used as an inner container of the general cooking and electric pressure cooker.

일반적으로 종래의 취사용기는 도 1에서와 같이, 석재용기(10)의 외측에 알루미늄합금을 주조하여 일체성형되는 알루미늄합금용기(20)로 이루어지되, 상기 알루미늄합금용기(20)의 바닥면(22)에 절개된 개구부(22a)가 형성되어 있다.In general, the cooker is made of an aluminum alloy container 20 formed by casting an aluminum alloy on the outside of the stone container 10, as shown in Figure 1, the bottom surface of the aluminum alloy container (20) The opening 22a cut | disconnected in 22 is formed.

상기 개구부(22a)는 주조금형의 용탕주입구와 대응되는 부위로서,The opening 22a is a portion corresponding to the molten metal inlet of the casting mold.

이는 알루미늄합금 주조시 금형의 용탕주입구가 가스배출구도 겸하므로 그 부위의 알루미늄합금 용융액에 많은 기포가 잔존하여 조직이 치밀하지 못하게되는 원인이 되므로 그 부분을 절개하여 개구부(22a)가 형성된 것이다.Since the molten metal inlet of the mold also serves as a gas outlet during the casting of the aluminum alloy, many bubbles remain in the aluminum alloy melt at the site, and thus the structure is not dense, so that the opening 22a is formed by cutting the portion.

이와 같이 제조된 상기 종래의 취사용기를 조리를 위해 가열시 석재용기(10)와 알루미늄합금용기(20)의 열팽창계수의 차이에 의해 두 용기간에 미세간격(t)이 발생한다.When the conventional cooker prepared as described above is heated for cooking, a fine interval t is generated between the two containers due to the difference in the coefficient of thermal expansion of the stone container 10 and the aluminum alloy container 20.

이로인해, 압력이 미세간격(t)에서 개구부(22a)로 유출되므로 압력용기로 사용할 수 없으며,Due to this, since the pressure flows out from the fine interval t to the opening 22a, it cannot be used as a pressure vessel.

상기 종래의 취사용기를 압력용기용으로 사용하기 위하여 석재용기(10)를 알루미늄합금용기(20)보다 돌출되게 하여 제작할 수도 있으나, 이 경우 돌출된 부위의 석재용기(10)가 쉽게 파손되는 문제점이 발생한다.In order to use the conventional cooker for the pressure vessel may be produced by protruding the stone container 10 than the aluminum alloy container 20, in this case, the problem that the stone container 10 of the protruding portion is easily broken. Occurs.

또한 상기 종래의 취사용기를 압력용기용으로 제작할 경우 알루미늄 등의 금속재 용기보다 그 두께를 두껍게하여 내구성을 지니게 하여 제작하므로 무게가 5~6㎏정도 되므로 취급이 불편한 문제점이 있다. In addition, when the conventional cooker is manufactured for pressure vessels, the thickness thereof is made thicker than that of metal containers such as aluminum, so that the weight is about 5 to 6 kg.

이에 본 발명은 상기한 문제점을 해결하고자 안출한 것으로,The present invention has been made to solve the above problems,

기포의 발생을 원천적으로 제거하고 나아가서 잔존하는 기포를 단조처리에 의하여 제거되어서 치밀한 조직을 제공하며,Eliminates the occurrence of bubbles at the source and furthermore, the remaining bubbles are removed by forging treatment to provide a dense tissue,

석재용기와 알루미늄합금용기의 적정두께를 도출하여 적절한 열보전성과 열효율을 가지면서도 적정한 강도를 유지하며 또한 취급이 용이할 정도의 무게를 갖는 취사용기 제조방법을 제공하는데 있다.It is to provide a method of manufacturing a cooker having a weight that is easy to handle while maintaining the appropriate strength while having the appropriate heat integrity and thermal efficiency by deriving the proper thickness of the stone container and aluminum alloy container.

이하 본 발명의 구성 및 작용을 첨부도면 도 2 내지 도 7을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to FIGS. 2 to 7.

본 발명의 취사용기(1)의 구성은 도 2에서와 같이,The structure of the cooker 1 of the present invention is as shown in FIG.

석재용기(10)의 외측으로 알루미늄합금을 주조하여 일체성형되는 외측용기(20)로 이루어지는 취사용기에 있어서,In the cooker which consists of the outer container 20 integrally molded by casting an aluminum alloy on the outside of the stone container 10,

석재용기(10)의 측벽(11) 및 바닥면(12)은 3mm 정도의 두께로 이루어지며,The side wall 11 and the bottom surface 12 of the stone container 10 is made of a thickness of about 3mm,

석재용기(10)의 측벽(11)의 높이는 취사용기(1) 전체높이의 2/3정도의 높이를 가지며,The height of the side wall 11 of the stone container 10 has a height of about 2/3 of the height of the entire cooking vessel 1,

석재용기(10)의 외측으로 성형되는 알루미늄합금용기(20)의 두께는 3mm정도로 이루어지며,The thickness of the aluminum alloy container 20 to be molded to the outside of the stone container 10 is made of about 3mm,

알루미늄합금용기(20)의 바닥면(22)은 630℃~500℃에서 단조처리된 것이다.The bottom surface 22 of the aluminum alloy container 20 is forged at 630 ℃ ~ 500 ℃.

특히 이와같이, 석재용기(10)의 측벽(11)의 높이는 취사용기(1) 전체높이의 2/3정도의 높이를 가지게 하는 이유는 취사 및 보온시 적정용량이 약 2/3 수준이기 때문이다.In particular, the height of the side wall 11 of the stone container 10 to have a height of about 2/3 of the height of the overall height of the cooker 1 because the appropriate capacity at cooking and warming is about 2/3 level.

또한, 석재용기(10)와 알루미늄합금용기(20)의 두께를 각각 3mm로 하여 제작하는 이유는 취급이 용이한 중량이면서도 적절한 강도를 유지하며, 또한 적절한 보온성과 열효율을 유지하도록 하기 위함이다.In addition, the reason why the thickness of the stone container 10 and the aluminum alloy container 20 is set to 3 mm, respectively, is to maintain proper strength while maintaining easy strength and proper thermal insulation and thermal efficiency.

이는 도 3 내지 도 6에서와 같이 취사용기의 직경을 200mm하고 두 소재의 두께를 2mm~12mm로 제작하여 열보전성, 취사시간, 두 소재간의 팽창으로 발생하는 간격차 및 무게등을 도출한 실험 그래프를 근거로 도출된 결과로서,This is a graph of experiments deriving the thermal integrity, cooking time, the gap between the two materials and the weight generated by making the diameter of the cooker 200mm and the thickness of the two materials to 2mm ~ 12mm as shown in Figure 3 to 6 As a result derived from

도 3은 취사용기의 두 소재의 두께를 1mm 에서 6mm로 제작하여 취사용기가 지니는 열 보전성을 도시한 그래프이며,Figure 3 is a graph showing the heat integrity of the cooker by making the thickness of the two materials of the cooker from 1mm to 6mm,

도 4는 취사용기의 두 소재의 두께를 1mm 에서 6mm로 제작하여 취사용기의 취시시간을 도시한 그래프이며,Figure 4 is a graph showing the cooking time of the cooker by making the thickness of the two materials of the cooker from 1mm to 6mm,

도 5는 취사용기의 두 소재의 두께를 1mm 에서 6mm로 제작하여 취사온도(약180℃)에서 두 소재 간의 간격차를 도시한 그래프이며,Figure 5 is a graph showing the difference between the two materials at the cooking temperature (about 180 ℃) by making the thickness of the two materials of the cooker from 1mm to 6mm,

도 6은 취사용기의 두 소재의 두께를 각각 1mm 에서 6mm로 제작하여 취사용기의 무게를 도시한 그래프이다.Figure 6 is a graph showing the weight of the cooker by making the thickness of the two materials of the cooker from 1mm to 6mm, respectively.

상기 도 3 내지 도 6의 실험데이터를 살펴보면Looking at the experimental data of Figures 3 to 6

두 소재의 두께가 3mm 이하 인 경우, If the thickness of both materials is 3mm or less,

도 3에서와 같이 보온시간이 20분 이하가 되므로 열보전성이 낮아져 취사용기의 보온효과가 떨어지게되며, 3, since the heat retention time is 20 minutes or less, as shown in FIG.

도 4에서와 같이 취사시간이 17분 이하가 되므로, 열이 취사용기에 빨리 전달되어 쉽게 가열되므로 밥을 지을때 타버리는 현상이 발생하며,Since the cooking time is less than 17 minutes as shown in Figure 4, heat is quickly transferred to the cooker and easily heated, so the phenomenon occurs when cooking rice,

도 5에서와 같이 취사용기를 180℃로 가열시 두소재간의 간격은 크게 벌어지지 않으나 대신 소재의 두께가 얇아 압력용기로 사용하기에 내구성이 약해지는 문제가 있다.As shown in FIG. 5, when the cooker is heated to 180 ° C., the spacing between the two materials does not greatly increase, but instead, the thickness of the material is thin so that durability is weak for use as a pressure vessel.

두 소재의 두께가 3mm이상 인 경우, If the thickness of the two materials is more than 3mm,

도 3에서와 같이 취사용기의 보온시간이 길어지므로 열보전성이 높아져 취사용기의 보온효과는 상승하나, As shown in FIG. 3, since the warming time of the cooker increases, the heat preservation is increased, and the warming effect of the cooker increases.

도 4에서와 같이 열효율이 낮아져 취사용기 전체를 가열하는데 시간이 오래 걸리며 이로인해 밥을 짓는 시간이 길어지며, As shown in Figure 4, the thermal efficiency is lowered, so it takes a long time to heat the entire cooker, thereby increasing the time to cook rice,

도 5에서와 같이 취사용기를 180℃로 가열시 두 소재간의 팽창계수 차이로 인하여 틈이 0.3mm 이상 벌어지게 되며,When the cooker is heated to 180 ℃ as shown in Figure 5 due to the difference in expansion coefficient between the two materials will be opened more than 0.3mm,

도 6에서와 같이 취사용기의 3㎏ 이상 되므로 무게가 너무 무거워서 취급하기가 불편하다.As it is more than 3㎏ of the cooker as in Figure 6, the weight is too heavy to handle is inconvenient.

그러므로 두 소재의 두께를 3mm정도로 할 경우 보온시간이 20분정도 유지되어 적절한 열보전성이 유지되며, 17분정도의 시간에 취사가 완료되므로 취사시간도 적절하다. 또한 두 소재간의 간격이 0.3mm이내가 되어 과다한 틈이 발생하지 않으며, 용기의 무게가 약 3㎏ 정도가 되므로 취급에 문제가 없다.Therefore, when the thickness of the two materials is about 3mm, the warming time is maintained for about 20 minutes, and the proper heat integrity is maintained, and the cooking time is also appropriate because cooking is completed in about 17 minutes. In addition, the gap between the two materials within 0.3mm does not cause excessive gaps, the weight of the container is about 3㎏ there is no problem in handling.

이와 같은 실험데이터를 근거로 각 소재의 두께를 균일한 3mm로 유지되게하여 제작함이 바람직하다.Based on the experimental data, it is preferable to maintain the thickness of each material at a uniform thickness of 3mm.

이하 본 발명의 취사용기 제조과정을 도 7a 내지 도 8을 참조하여 설명한다.Hereinafter, a manufacturing process of the cooker of the present invention will be described with reference to FIGS. 7A to 8.
