본 발명은 주로 세라믹과 규석으로 제조되는 내열조리용기의 저면에 자성체 피막층을 얇게 도막처리시켜주어 내열조리용기를 인덕션 렌지(Induction Heating Cooker)에서 사용할 수 있도록 저면에 자성체 피막층을 형성한 내열조리용기를 제공받을 수 있도록 한 내열조리용기 저면의 자성체 피막층 형성방법에 관한 것이다.The present invention is a heat-resistant cooking vessel having a magnetic coating layer formed on the bottom surface of the heat-resistant cooking container mainly made of ceramic and silica, so that the magnetic coating layer is thinly coated on the bottom of the heat-resistant cooking vessel so that the heat-resistant cooking container can be used in an induction heating cooker. It relates to a method for forming a magnetic coating layer on the bottom of the heat-resistant cooking container to be provided.
본 발명에서 자성체 피막층을 도막처리시키는 재질로서는 은(銀)용액을 채택하고 있으며, 은(銀)은 자성체 중에서 열전도율과 전기를 통과시키는 효율이 가장 우수하고 값이 비교적 저렴하기 때문에 채택사용한 것이다.In the present invention, a silver solution is used as a material for coating the magnetic coating layer, and silver is used because it has the best thermal conductivity and efficiency of passing electricity among magnetic materials and its value is relatively low.
본 발명은 내열조리용기와 같은 주방기구에 자성체 피막층을 형성시키므로서 인덕션 렌지에서 유용하게 사용할 수 있도록 한 것인데, 인덕션 렌지의 작동원리는 첨부도면 제 3 도에 도시되어 있다.The present invention is to be useful in an induction stove by forming a magnetic coating layer on a kitchen appliance such as a heat-resistant cooking vessel, the operation principle of the induction stove is shown in FIG.
즉, 인덕션 렌지의 내부에는 히팅코일(Heating Coil)이 내설되어 있는데, 전원이 입력되면 자속(磁束)이 발생하여 인덕션 렌지의 상판(3) 위에 안치되어 있는 자성체로된 주방기구에까지 자속이 유도(Induction)되어 주방기구의 바닥면에서 맴돌이 전류를 발생시킴으로써 그로 인한 열이 발생하게 되는 것이다.That is, a heating coil is installed inside the induction stove. When the power is input, magnetic flux is generated, and the magnetic flux is induced to the kitchen utensil made of magnetic material placed on the top plate 3 of the induction stove. Induction) generates eddy currents at the bottom of the kitchen utensils, resulting in heat generation.
그러나, 비자성체로 된 주방기구일 때에는 주방기구에 자속이 유도되지 못하여 맴돌이 전류가 발생하지 않으므로 인덕션 렌지에서의 사용이 불가능한 것이다.However, in the case of a non-magnetic kitchen utensils, the magnetic flux is not induced to the kitchen utensils, so no eddy current is generated, so it is impossible to use the induction stove.
즉, 도자기, 세라믹, 규석등으로 된 주방기구 특히 내열조리용기는 여타의 자성물질을 함유하고 있지 않기 때문에 인덕션 렌지에서 발생된 자속이 유도되지 못하고 차단되므로 사용할 수가 없는 단점이 있었던 것이다.In other words, kitchen utensils, especially heat-resistant cooking vessels made of ceramics, ceramics, silica, etc., do not contain any other magnetic materials, so the magnetic flux generated in the induction stove is not induced, and therefore, it cannot be used.
따라서 본 발명은 비자성체로 된 주방기구 특히, 본체가 도자기, 차이나, 세라믹등으로 된 내열조리용기(1)라 할지라도 이를 인덕션 렌지에서 효과적으로 사용할 수 있도록 하기 위하여 내열조리용기(1)의 저면에 자성의 성질을 갖는 물질 즉, 자성체 피막층(4)을 얇게 도막처리시켜 줌으로써 인덕션 렌지에서 발생하는 자속을 효율적으로 유도하여 자기유도(磁氣誘導)에 의해 맴돌이 전류가 발생할 수 있도록 한 것이다.Therefore, the present invention is a non-magnetic kitchen utensil, in particular, even if the heat-resistant cooking container (1) made of ceramics, China, ceramics, etc. in order to effectively use it in the induction stove to the bottom of the heat-resistant cooking container (1) By thinly coating a material having a magnetic property, that is, the magnetic coating layer 4, the magnetic flux generated in the induction stove is efficiently induced so that a eddy current can be generated by magnetic induction.

Diluting the silver solution mixed with (2-7%) at an appropriate ratio to form a coating layer 4 by coating the silver solution, the solvent is a volatile fluid 100: 11 to 13 in the silver solution It is added in a ratio of% to make a gel or sol state and stirred well, and the stirred silver dilution solution has a thickness of about 0.09 to 0.11 m / m on the bottom of the heat-resistant cooking container (1). After primary printing by the screen printing method so that the coating film treatment, and hot-air dried at room temperature of 38 ~ 42 ℃ for 2 hours, the silver dilution solution is again screened to a thickness of 0.18 ~ 0.22m / m After the second printing by the printing method and the hardness film treatment, and hot-air dried again for 2 hours at a room temperature of 38 ~ 42 ℃ and calcined at a high temperature of about 800 ℃ The magnetic material coating layer of the coated film is treated so as to form a thickness of 0.13~0.16m / m.

상술한 바와 같은 제조공정에 따라 형성되는 본 발명의 내열조리용기는 그 소성과정에서 소성(가열-숙성-냉각)이 서서히 이루어지도록 하는 것은 도막처리된 자성체 피막층(4)이 용기본체와의 접착력을 양호하게 하기 위한 것이며, 또한 내열조리용기 본연의 성질등이 변화되지 않도록 하기 위한 것이다.The heat-resistant cooking container of the present invention formed in accordance with the manufacturing process as described above so that the firing (heat-maturation-cooling) is gradually carried out during the firing process, the coating of the magnetic film layer (4) of the coated film to the adhesion of the container body It is for making it favorable, and for preventing the nature, etc. of a heat resistant cooking container from changing.
이렇게 소성이 완료된 상태에서 도막처리된 자성체 피막층(4)의 두께는 0.15m/m 내외가 되도록 하는 것이 가장 큰 효율을 얻을 수 있는 것이며, 또한 본 발명에서는 자성체 피막층(4)을 내열조리용기(1)에 스크린 인쇄법에 의하여 직접 도막처리하지 않고, 별도의 자성체 피막층을 제조하여 이를 내열조리용기(1)에 증착시키는 간접도막처리방법도 용이하게 실시할 수 있으며, 이러한 간접 증착방법에 의해 제조된 내열조리용기도 동일한 효과를 얻을 수 있는 것이다.In this state, the thickness of the magnetic coating layer 4 that has been coated in the state where the firing is completed is about 0.15 m / m, so that the greatest efficiency can be obtained. In addition, in the present invention, the magnetic coating layer 4 is formed of a heat-resistant cooking container (1). Indirect coating treatment method to prepare a separate magnetic coating layer and deposit it on the heat-resistant cooking container (1) without directly coating the coating film by the screen printing method, can be easily carried out. Heat-resistant cooking containers can also achieve the same effect.
상술한 바와 같은 자성체 피막층의 형성방법에 의하여 도막처리된 자성체 피막층을 갖는 내열도자기는 인덕션 렌지에서 효율적이고 유용하게 사용할 수 있는 것이다.Heat-resistant ceramics having a magnetic coating layer coated by the method of forming the magnetic coating layer as described above can be used efficiently and efficiently in an induction stove.
