본 발명은 전자레인지용 조리기에 관한 것이며, 특히 발열성과 축열성을 가진 조리기에 관한 것이다.The present invention relates to a cooker for a microwave oven, and more particularly to a cooker having heat generation and heat storage properties.

세계적으로 널리 보급되고 있는 전자레인지는 각종음식물을 신속히 조리할 수는 있으나 생선 또는 육류등과 같은 음식물의 표층을 황갈색화(그으름)하지는 못하므로 맛갈스러움을 잃게하며 또한 밥 또는 국등이 일반 가스등의 열원에 위하여 조리하는 것보다 맛이 있게 되지 못하는 결점이 있었다.Microwaves, which are widely used all over the world, can cook various foods quickly, but they do not tan the surface of foods such as fish or meat. There was a drawback that it did not become more delicious than cooking for a heat source.

위 결점중 전자의 것은 개선하기 위하여 전자레인지의 내부에 전열선을 추가로 내장한 것이 있으나 별도의 에너지를 필요로 하므로 경제적이지 못하고 또한 최근에는 고주파손실재인 페라이트 또는 티탄산바륨의 주성분으로 하여 만든 발열체를 특수형상의 용기로 만들어 음식물의 표층을 황갈색화하려는 시도가 있었다. 즉, 일본국 특허출원공고 소 53-44694에서는 티탄산바륨과 같은 유전재와 유크립타이트를 주성분으로 하는 소결체로서 전자파 가열장치용 용기를 만들어 이를 전자레인지에 넣어서 전자파에너지를 흡수하고 그 흡수에너지에 의하여 용기를 발열시키는 것을 시도하였으나 그 발열온도가 4분간에 섭씨 300도에 불과하였으며, 일본국 특허출원공고 소 55-20614에서는 Li2O(1-y)Al2O3·yFe2O3·XSiO2로 표시되는 세라믹재료에 의하여 전자파에너지를 흡수하는 발열체를 개시하고 있으나 이 발열체도 내열충격성은 우수하나 전자레인지 내부에 넣어서 사용하는 경우에 4분간에 도달한 온도는 섭씨 250도에 불과하였다. 그리고 일본국 특허출원공개 소 55-137183에서는 고주파손실재로서 자기(磁器 )반도체를 만들어 고주파를 조사(照射)하여 발열하는 것을 개시하고 있으나 자기반도체의 표면온도는 1분간 전자파를 조사한 결과 섭씨 220도에 불과하여 상기한 것들을 전자레인지의 결점인 음식물의 황갈색화가 불가능하고 밥 또는 국둥이 일반적인 가스등의 열원에 의하는 것보다 그 맛이 좋지 못하다는 결점을 해결하지 못하고 있다.Among the above shortcomings, the former has additional heating wires inside the microwave oven to improve it, but it is not economical because it requires extra energy, and in recent years, special heating elements made of ferrite or barium titanate, which are high-frequency loss materials, Attempts have been made to turn the surface layer of food into a brown container. In Japanese Patent Application Publication No. 53-44694, a sintered body composed mainly of a dielectric material such as barium titanate and krypite, a container for an electromagnetic heating device is made and placed in a microwave oven to absorb electromagnetic energy and absorbed by the absorbed energy. Attempted to heat the vessel, but the exothermic temperature was only 300 degrees Celsius in 4 minutes, and in Japanese Patent Application Publication 55-20614, Li 2 O (1-y) Al 2 O 3 · yFe 2 O 3 · XSiO Although a heating element that absorbs electromagnetic energy by a ceramic material represented by 2 is disclosed, the heating element also has excellent thermal shock resistance, but when used in a microwave oven, the temperature reached for 4 minutes was only 250 degrees Celsius. In addition, Japanese Patent Application Publication No. 55-137183 discloses the creation of a magnetic semiconductor as a high-frequency loss material to generate heat by irradiating high-frequency, but the surface temperature of the magnetic semiconductor is 220 degrees Celsius after 1 minute of irradiation. However, the above-mentioned things cannot solve the drawback that the yellowing of the food, which is a drawback of the microwave oven, is impossible, and the taste is not as good as that of the rice or the soup by the heat source such as general gas.

본 발명자는 상기한 종래 기술 및 전자레인지의 결점들을 예의 검토 연구한 바 상기한 종래 기술에서 사용되는 고주파 손실재 예를들면 자성재는 이를 제조할때 주성분화합물들의 순도를 최대한 높은 것을 사용하여 초투자율을 높이고 자성손실을 최소화한 것이기 때문에 자성손실이 적을 수록 그 성능이 양호한 코어등에는 적합하나 발열 또는 축열을 목적으로 할때 사용하는 자성재는 자성손실이 커야 양호한 성능을 발휘하는 것임을 알게 되었다. 그러한 현재까지 알려진 고주파 손실재는 코어등에 사용하기 위하여 개발된 것이므로 이를 사용하여 발열 또는 축열을 위한 제품을 만들면 당연히 기 발열온도 및 측열성능이 떨어지게 된다.The present inventor has studied and studied the above-mentioned drawbacks of the prior art and microwave oven. The high frequency loss material used in the prior art, for example, the magnetic material, has a high permeability by using the highest purity of the principal component compounds when manufacturing the same. As the magnetic loss is smaller, the higher the magnetic loss, the higher the performance and the better the performance. However, the magnetic material used for heat generation or heat storage has a high magnetic loss to show good performance. Such high frequency loss materials known to date have been developed for use in cores, etc. Therefore, if a product for heat generation or heat storage is used, the heat generation temperature and the thermal insulation performance of course decrease.

본 발명에서는 위와 같은 사실과 고주파손실재에 규사를 혼합하면 고주파손실이 증대된다는 사실을 감안하여 짧은 시간에 높은 발열온도를 발휘하는 조리기를 제공하는 것을 목적으로 한다.In the present invention, in view of the fact that the high frequency loss is increased when the silica sand is mixed with the above facts and the high frequency loss material, an object of the present invention is to provide a cooker exhibiting a high exothermic temperature in a short time.

본 발명의 다른 목적은 음식물의 황갈색화가 가능한 조리기를 제공하는 것이다.Another object of the present invention is to provide a cooker capable of tanning food.

본 발명의 또다른 목적을 축열성능이 양호하므로 음식물의 맛이 좋은(기존의 열원과 동일한)조리기를 제공하는 것이다.Another object of the present invention is to provide a cooker having a good taste (same as an existing heat source) because the heat storage performance is good.

본 발명은 위의 목적은 달성하기 위하여 내열자기판에 홈을 형성하여 고주파손실재와 규산질함유 무기재료를 혼합소성한 고주파 고손실성 세라믹 부재를 설치한 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that a high frequency high loss ceramic member is formed by mixing a high frequency loss material and a siliceous-containing inorganic material by forming a groove in the heat-resistant magnetic substrate.

본 발명은 고주파손실재가 가지고 있는 전자파흡수능과 다중복사에 의한 전자파 흡수능 향상원리를 고려하고 전자파투과성인 규산질함유 무기재료에 의하여 다중복사구조를 형성함과 동시에 강도를 보강함으로서 전자파흡수능을 크게 보강시키므로서 발열온도가 획기적으로 상승되며, 내열성, 내충격강도가 우수하고 축열성능이 양호한 조리기를 얻을 수 있다.The present invention considers the electromagnetic wave absorbing ability of the high-frequency loss material and the principle of improving the electromagnetic wave absorbing ability by multiple radiation, and greatly enhances the electromagnetic wave absorbing ability by forming a multi-radiation structure by the silicic acid-containing inorganic material which is electromagnetic wave permeable and strengthening the strength. Exothermic temperature is dramatically increased, it is possible to obtain a cooker excellent in heat resistance, impact strength and excellent heat storage performance.

이하 본 발명을 실시예 도면에 의하여 설명한다.Hereinafter, the present invention will be described by way of example drawings.

1은 내열자기(磁器)판으로서 종래와 같은 재질로 만들어 그 밑면에 받침돌기(2)와 상부주연에 손잡이(3)이 형성되어 있다. 4는 내열자기판(1)의 표면에 형성된 세라믹부재 설치홈으로서 그 홈에 자성재, 유전재, 도전재와 그 폐기물 분쇄물과 같은 고주파손실재를 1종 이상으로 하고 모래, 점토, 지르콘, 유크립타이트, 코디에라이트, 스테아타이트와 폐도기등 산업폐기물 분쇄물 등과 같은 규산질함유 무기재료를 1종 이상 혼합소성한 고주파고손실성 세라믹부재(5)를 설치한다. 세라믹부재(5)는 내열자기판(1)의 표면위로 돌출하도록 설치하거나 세라믹부재(5)를 내열자기판(1)의 표면 아래로도 설치할 수 있다.1 is a heat-resistant magnetic plate made of the same material as the prior art, and the base 3 and the handle 3 are formed on the bottom of the base protrusion 2. 4 is a ceramic member mounting groove formed on the surface of the heat-resistant magnetic substrate (1), at least one of high-frequency loss materials such as magnetic materials, dielectric materials, conductive materials, and waste crushed products, and includes sand, clay, zircon, A high frequency high loss ceramic member 5 is prepared in which at least one kind of siliceous-containing inorganic material such as eutectic, cordierite, steatite and waste pottery is mixed and fired. The ceramic member 5 may be installed to protrude above the surface of the heat resistant magnetic substrate 1, or the ceramic member 5 may be installed below the surface of the heat resistant magnetic substrate 1.

또한 세라믹부재(5)는 봉상체로 만들어 제 2 도와 같이 설치할 수도 있고, 판상체로 만들어 제 3 도와 같이 설치할 수도 있다. 제 3 도와 같이 설치할 경우에는 돌기(6)가 세라믹부재(5)의 위로 돌출된다. 또한 세라믹부재(5)의 배치는 구상체로된 제 4a 도의 것으로부터 제 4b, c 도와 같이 봉상체 또는 판상체의 것을 배치할 수 있으며 제 4d 도와 같이 타원형의 것도 좋으며 기타 임의 형상으로도 할 수 있다.In addition, the ceramic member 5 may be made of a rod-like body and installed as a second tile, or may be made of a plate-like body and installed as a third tile. In the case of installation with the third tile, the projection 6 protrudes above the ceramic member 5. In addition, the arrangement of the ceramic member 5 may be arranged in the shape of a rod or a plate like the spherical body of Figs. 4a to 4b, c, and may be an elliptical one such as the 4d tile, or may be any other shape. .

이상과 같은 본 발명의 조리기를 전자레인지 내에 넣고 100초내외 가열하면 섭씨 1000도 정도로 세라믹부재(5)가 적열되는바(상세한 조성은 본인의 1990년 특허원 제10710호 참조) 본 발명조리기를 전자레인지의 회전테이블로 겸용하거나 회전테이블이 없는 전자레인지의 경우에는 전자레인지의 바닥에 놓고 종래의 조리용기를 올려놓거나 생선, 육류 같은 음식물은 직접 올려놓고 조리를 할 수 있다. 이때 가열온도를 높게할 경우에는 제 1 도와 같은 구성의 것을 사용하며 가열온도를 낮게할 경우에는 제 3 도와 같은 구성의 것을 사용할 수 있고 또한 생선, 육류등의 표층을 황갈색화할 경우에는 제 1 도의 것과 제 3 도의 것을 적의 선택하여 황갈색화 정도를 조정할 수 있다. 그리고 본 발명의 조리기는 축열성능이 양호하므로 전자레인지의 전원을 차단한 후에도 예를 들면 밥을 뜸을 들일 수 있을 뿐 아니라 국물등이 진하게 울어나며 조리가 완료된 후에도 오랫동안 음식물이 식지않게 되고, 또한 음식물의 황갈색화가 가능하므로 미각을 증진할 수 있으며 가스레인지와 같은 다른 열원용으로도 사용될 수 있다.When the cooker of the present invention as described above is heated in a microwave oven for about 100 seconds, the ceramic member 5 is heated to about 1000 degrees Celsius (for the detailed composition, refer to 1990 Patent Application No. 10710 of the present invention). In the case of a microwave oven that does not have a rotating table or a rotating table of the range, it can be placed on the bottom of the microwave and a conventional cooking container or a food such as fish or meat can be placed directly. In this case, when the heating temperature is increased, the same structure as that of the first degree may be used. When the heating temperature is lowered, the same thing as the third degree may be used. When the surface layer of fish, meat, etc. is yellowish brown, The degree of tanning can be adjusted by appropriately selecting the one of FIG. 3. And since the cooker of the present invention has good heat storage performance, for example, the steam can be steamed even after the power of the microwave is cut off, and the soup is soaked, and the food is not cooled for a long time after the cooking is completed. It can be tanned, which enhances the taste and can be used for other heat sources such as gas ranges.

이상과 같은 본 발명은 세라믹부재가 고주파고손실성을 가지므로 발열성과 축열성이 양호하여 각종 음식물의 조리를 맛있게 할 수 있으며 오랫동안 식지않으며 황갈색화가 가능하므로 맛갈스러움을 가지는 등의 효과가 있다.In the present invention as described above, since the ceramic member has high frequency and high loss property, heat generation and heat storage properties are good, which makes it possible to cook various foods, and it does not cool for a long time, so that it can be tanned.
