본 발명은 음식물 조리용 발열 도자기에 관한 것으로서, 더욱 상세하게는 전자레인지를 이용한 음식물 조리시 복사열을 발생시켜 음식물 조리가 보다 효과적으로 이루어질 수 있도록 하는 발열 도자기에 관한 것이다.The present invention relates to a heating porcelain for food cooking, and more particularly, to a heating porcelain to generate a radiant heat when cooking food using a microwave oven so that the food can be cooked more effectively.

일반적으로 전자레인지는 음식을 익히거나 데우도록 하는 조리기기 중의 하나로서, 현재 사용되는 조리기기 가운데서 가장 간편하게 음식물을 조리해 낼 수 있도록 하는 장점으로 인해 실생활에서 가스레인지와 함께 가장 널리 사용되어지고 있는 조리기기이다.In general, the microwave oven is one of the cooking appliances that cook or warm food, and the cooking is most widely used in the real life with the gas range due to the advantage of being able to cook food most easily among the current cooking appliances. Appliance.

이러한 전자레인지는 용기에 담긴 음식물에 마이크로웨이브를 조사하여 음식물에 포함된 수분을 직접 가열하는 원리로 조리함으로서, 상기 마이크로웨이브를 반사시킬 수 있는 금속류 용기의 사용이 불가능하며, 고강도 유리용기나 세라믹 도자기 등의 내열성 특수 용기를 필요로 하는 단점이 있었으며, 전자레인지용 용기를 사용할 경우에도 마이크로웨이브가 음식물의 표면에 직접 조사될 수 있도록 용기의 뚜껑을 개방함으로서, 음식물의 수분의 증발되고 영양소의 파괴가 발생하게 되는 문제점이 있었다.Such microwave ovens are cooked on the principle of directly heating the moisture contained in the food by irradiating the microwaves in the food in the container, it is impossible to use a metal container that can reflect the microwave, high-strength glass container or ceramic ware There was a disadvantage of requiring a heat-resistant special container such as, and even when using a microwave oven container by opening the lid of the container so that the microwave can be directly irradiated to the surface of the food, water evaporation of food water and destruction of nutrients There was a problem that occurred.

이러한 전자레인지를 통한 음식물 조리의 문제점을 해결하기 위하여 음식물을 담은 용기가 마이크로웨이브를 받아 자체 발열하여 내부에 담긴 음식물을 조리할 수 있도록 하는 전자레인지용 발열 도자기의 개발이 활발하게 진행되어 다수 문헌에 기재되어 있다.In order to solve the problem of food cooking through a microwave oven, a microwave oven is actively developed to develop a microwave oven that allows food containers to receive microwaves and to cook food contained therein. It is described.

그러나 종래 음식물 조리용 발열 도자기는 전자레인지에서 마이크로파로 발열시킬 수 있는 최상온도가 80~120℃ 정도로서 단순히 음식물의 수분만을 이용하여 음식물 조리가 이루어지는 문제점이 있었다.However, the conventional food cooking heating ceramics has a problem that the food can be cooked using only moisture of the food as the highest temperature that can be generated by microwave in the microwave is about 80 ~ 120 ℃.

본 발명은 상기한 종래 기술에서의 문제점을 개선하기 위해 제안된 것으로서, 음식물 조리용 도자기가 마이크로파를 흡수한 후 자체 복사열을 통해 음식물 조리가 이루어질 수 있도록 함으로서 음식물의 조리효율을 극대화 하는데 목적이 있다.The present invention has been proposed to improve the above problems in the prior art, the purpose of maximizing the food cooking efficiency by allowing food cooking to be made through its own radiant heat after the food cooking ceramics absorb microwaves.

상기 목적을 이루기 위한 본 발명의 발열 도자기는, 점토 20~40중량%와, 멀라이트 15~25중량%와, 페라이트 15~23중량%와, 도석 5~10중량%와, 백토 5~20중량%와, 물 10~35중량%와, 규산소다 0.2~1 중량%가 혼합되어 형성되어짐을 특징으로 한다.Heat generation ceramics of the present invention for achieving the above object, 20 to 40% by weight of clay, 15 to 25% by weight of mullite, 15 to 23% by weight of ferrite, 5 to 10% by weight of pottery stone, 5 to 20% by weight of clay %, 10 to 35% by weight of water, and 0.2 to 1% by weight of sodium silicate are formed by mixing.

이러한 본 발명의 음식물 조리용 발열 도자기는, 전자레인지를 이용한 음식물 조리시 도자기에서 발생하는 복사열에 의해 고온 조리가 이루어질 수 있게 됨으로 음식물의 수분을 유지하는 가운데 보다 신속한 음식물 조리가 이루어질 수 있는 효과를 나타낸다.
The food cooking heating ceramics of the present invention, the high temperature cooking can be made by the radiant heat generated in the ceramics when cooking food using a microwave oven, while maintaining the moisture of the food, the food cooking can be made more quickly. .

이하, 본 발명의 구체적인 실시 예를 살펴보기로 한다.Hereinafter, a specific embodiment of the present invention will be described.

먼저, 본 발명 발열 도자기의 제작시 일 실시 예에 따른 혼합성분을 살펴보면, 도자기의 주재료인 점토 25중량%와, 산화알루미늄과 산화규소의 혼합물인 멀라이트(mullite) 20중량%, 산화철과 망간 그리고 크롬의 합성물질인 페라이트 20중량%, 도자기의 원료 원석인 도석 9중량%와, 점토와 함께 도자기 재료로 사용되는 백토 10중량%와, 물 20중량%와, 융해 및 해교제 역할을 하기 위한 규산소다 1중량%를 혼합하게 된다.First, looking at the mixed components according to an embodiment of the present invention to produce a heating ceramics, 25% by weight of clay, which is the main material of ceramics, 20% by weight of mullite (mullite) of a mixture of aluminum oxide and silicon oxide, iron oxide and manganese and 20% by weight of ferrite, a synthetic material of chromium, 9% by weight of porcelain, a raw material of porcelain, 10% by weight of white clay used as a ceramic material with clay, 20% by weight of water, and silicic acid for melting and peptizing agent 1% by weight of soda is mixed.

특히, 상기 혼합과정에서 발열의 핵심물질인 페라이트는 15~23중량% 범위 내에서 혼합이 이루어짐이 바람직한데, 15중량% 이하로 혼합이 이루어지면 발열 효과가 현저히 떨어지게 되고 23중량% 이상으로 과도하게 혼합되어지면 발열효과는 좋으나 소성과정에서 도자기의 외부 변형이 심하게 발생하게 된다.In particular, the ferrite core material of the exotherm in the mixing process is preferably mixed within the range of 15 ~ 23% by weight, if the mixing is less than 15% by weight, the exothermic effect is significantly reduced and excessively over 23% by weight When mixed, the heating effect is good, but the external deformation of ceramics occurs severely during the firing process.

따라서 발열효과(230~250℃)를 유지하기 위해서는 15~23중량%의 범위를 유지시켜야 한다.Therefore, in order to maintain the exothermic effect (230 ~ 250 ℃) should be maintained in the range of 15 to 23% by weight.

또한, 점토성분은 화강암질의 암석이 풍화되어 형성된 와목점토가 사용됨이 바람직하다.In addition, it is preferable that the clay component is used as a granite clay formed by weathering the granite rock.

와목점토라 함은 일반 점토에 비해 상대적으로 점력이 높은 특성을 갖는 것으로서, 일반 점토는 현미경으로 입자를 관찰해 보았을 때 입자 표면이 당구공 처럼 둥글고 매끄러운데 비해 와목점토는 밤까시 처럼 표면이 불규칙적으로 돌출된 형상을 이루는 특성을 갖고 있다.Furnace clay is characterized by relatively higher viscosity than ordinary clay. In general clay, the surface of particles is round and smooth like a billiard ball when viewed under a microscope. It has the property of forming a protruding shape.

이와 같은 조성으로 혼합이 이루어진 혼합물을 1~2시간 동안 볼밀로 믹싱을 실시하고 믹싱된 원료를 석고틀에 부어서 도자기 용기 형상을 만들어 통상의 제작 과정에 따라 건조 후 소성작업을 실시하게 된다.Mixing the mixture made in such a composition by a ball mill for 1 to 2 hours and pour the mixed raw material to the plaster mold to form a ceramic vessel shape is dried according to the usual manufacturing process and then firing.

즉, 도자기 성형과정은 일반 도자기 성형과정과 동일하게 이루어지는데, 그 일 예로 소성과정에서는 초벌구이(800~850℃, 6시간) 후 재벌구이(1200~1300℃, 3시간)작업이 실시되어지게 되는 것이다.In other words, the ceramic molding process is performed in the same manner as the general ceramics molding process. For example, in the firing process, the chaebol roasting (800 ~ 850 ℃, 6 hours) is performed after the chaebol roasting (1200 ~ 1300 ℃, 3 hours). will be.

한편, 본 발명에서는 이와 같이 성형이 이루어진 도자기 용기의 표면에 논스틱(non-stick) 및 발열성 향상을 위한 세라믹코팅을 2회 실시하게 된다.On the other hand, in the present invention, the ceramic coating for improving non-stick and exothermic properties is performed twice on the surface of the ceramic container formed as described above.

세라믹코팅 과정에서는 세라믹 원료를 용기 표면에 형성시킨 후 20분 동안 60℃ 에서 예열, 그리고 10분 동안 230℃에서 소성, 마지막으로 10분 동안 60~70℃에서 냉각 건조를 실시함이 바람직하다.In the ceramic coating process, after forming the ceramic raw material on the surface of the container, it is preferable to perform preheating at 60 ° C. for 20 minutes, calcining at 230 ° C. for 10 minutes, and finally cooling drying at 60 to 70 ° C. for 10 minutes.

이와 같이 제작이 이루어진 본 발명의 음식물 조리용 발열 도자기는 전자렌지를 이용한 음식물 조리시 도자기 자체의 복사열에 의해 보다 효과적인 음식물 조리가 이루어질 수 있게 된다.The food cooking heating ceramics of the present invention made as described above can be more effectively cooked by the radiant heat of the ceramics itself when cooking food using a microwave oven.

즉, 일반 도자기 용기는 전자렌지에서 마이크로파로 발열시킬 수 있는 최고온도가 80~120℃ 인데 반하여, 본 발명의 발열소지로 제작된 도자기 용기는 전자렌지에서 2~3분이 경과되면 도자기 복사열에 의해 최고 약 230~250℃ 까지 발열이 이루어지게 되어 음식물의 수분을 유지하는 가운데 음식물 조리가 이루어지게 됨은 물론 이에 따른 조리시간을 단축시킬 수 있는 효과를 나타내게 된다.
In other words, the general porcelain vessel is the highest temperature that can be generated by microwave in the microwave oven is 80 ~ 120 ℃, whereas the porcelain vessel made of the heating element of the present invention is the highest by the radiant heat porcelain 2 to 3 minutes in the microwave oven The heat is generated up to about 230 ~ 250 ℃ to maintain the moisture of the food while cooking is made of food as well as it can reduce the cooking time accordingly.

한편, 본 발명의 다른 실시 예에 따른 도자기 조성으로는, 산하마그네슘과 탄소섬유가 기능성 물질로 첨가되어질 수 있게 된다.On the other hand, as a ceramic composition according to another embodiment of the present invention, magnesium and carbon fiber can be added as a functional material.

즉, 이때에는 도자기의 주재료인 점토 23중량%와, 산화알루미늄과 산화규소의 혼합물인 멀라이트(mullite) 20중량%, 산화철과 망간 그리고 크롬의 합성물질인 페라이트 18중량%, 도자기의 원료 원석인 도석 7중량%와, 점토와 함께 도자기 재료로 사용되는 백토 10중량%와, 물 16중량%와, 내화성이 뛰어난 산화마그네슘 3중량%와, 탄소섬유 2중량%, 그리고 규산소다 1중량%를 혼합하게 된다.In other words, 23% by weight of clay, which is the main material of ceramics, 20% by weight of mullite, which is a mixture of aluminum oxide and silicon oxide, 18% by weight of ferrite, which is a composite material of iron oxide, manganese, and chromium, and raw materials of porcelain 7% by weight of pottery, 10% by weight of clay, which is used as a porcelain material together with clay, 16% by weight of water, 3% by weight of magnesium oxide having excellent fire resistance, 2% by weight of carbon fiber, and 1% by weight of silicate Done.

이와 같이 산화마그네슘과 탄소섬유가 첨가된 혼합 조성을 이루게 되면 마이크로파에 의한 발열 시 산화마그네슘이 페라이트와 반응하여 도자기의 복사열 발생을 극대화시키게 되어 도자기의 내열성을 더욱 극대화시키게 된다.As such, when a mixed composition in which magnesium oxide and carbon fiber are added, magnesium oxide reacts with ferrite during heat generation by microwaves, maximizing radiant heat generation of ceramics, thereby maximizing heat resistance of ceramics.

또한, 탄소섬유는 금속보다 가벼우면서도 금속에 비해 강도와 탄성이 뛰어나며 내열성, 내충격성이 좋기 때문에 도자기의 강도 강화 및 내열특성을 향상시키는 효과를 나타낼 수 있게 된다.
In addition, carbon fibers are lighter than metals, but have superior strength and elasticity, and are excellent in heat resistance and impact resistance compared to metals, and thus may exhibit an effect of improving strength and heat resistance of ceramics.

그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 발열 도자기 성분이 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다.In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the heating ceramic component of the present invention may be variously modified and implemented by those skilled in the art.

예를 들면, 기능성 향상을 위해 재료 혼합과정에서 추가적인 성분이 혼합되어질 수 있게 된다.For example, additional ingredients may be mixed during material mixing to improve functionality.

따라서, 이와 같은 변형된 실시예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.Therefore, it should be understood that such modified embodiments should not be understood individually from the technical spirit and scope of the present invention, and such modified embodiments should be included in the appended claims of the present invention.
