釜へのこびりつきが発生するという問題点があった。However, since the coating of the inner surface of the cooking vessel in the inner pot of the conventional rice cooker described above is resin-coated with a fluororesin, its non-affinity performance is high. Due to this feature, there is a drawback that the adhesion to the metal material is weak. Further, the fluororesin has a soft hardness, and when it is pierced by a sharp metal object, it is damaged and the metal material of the cooking container is exposed. In order to solve these problems, there is an example in which ceramics are coated instead of the fluororesin, but ceramics have low incompatibility performance, and when used as an inner pot of a rice cooker, There is a problem in that the cooked rice sticks to the inner pot.

れる。Next, in order to form a display body 5 for displaying scales, patterns, characters, etc., a recess 4 is formed at a predetermined position. Pressure is applied from the inner surface side of the inner pot 1 to the middle with a press blade having a shape and width corresponding to the display body 5. When pressure is applied from the inside by the press blade, the ceramic coating 3 and the metal material 2 are compressed in a faulty manner and are depressed in the shape of a square groove. Then, as shown in FIG. 1, the exposed surface of the metal material 2 of the metal is formed above and below the rectangular groove-shaped recess 4. A silicone resin coating material conforming to the Food Sanitation Law is applied to the cut-in concave portion 4, heated at a predetermined temperature, and baked into the concave portion 4 through the exposed surface.

る。According to the present embodiment, since the surface of the metal material 2 is processed into the fine irregularities 7 to form the ceramic coating 3, the adhesion between the metal material 2 and the ceramic coating 3 is enhanced. . Furthermore, since the hardness of ceramics is high, the adhesion between the metal material 2 and the ceramic coating 3 is further enhanced. Further, unlike the conventional fluororesin coatings 8 and 9, the ceramic coating 3 does not substantially contain a resin component, and since the ceramic has a high hardness, it has a high surface that is not damaged even when it is struck by a sharp metal object. Hardness is obtained. Moreover, good releasability can be obtained by using silicon, silicone oil, or both mixed in the ceramic coating 3. That is, in the case of a rice cooker, sticking of cooked rice to the inner pot is prevented. Therefore, it is possible to provide an inner pot with good cleanability. Further, since the display body 5 is formed so as to be embedded in the concave portion 4, it can be firmly bonded. Furthermore, since the silicon resin coating film 6 is in contact with the exposed surface of the metal material 2 in forming the film, the bond with the metal material 2 is strengthened. In the case of a ceramic coating similar to the ceramic coating 3, the same material as the underlying ceramic coating 3 is used, and the ceramic coating 3 is firmly bonded.

となる。Further, ceramics emit a large amount of far infrared rays. Far infrared rays have the highest emissivity where heat reaches the object to be heated directly without the need for any medium, and moreover the heat is absorbed efficiently, so if the cooking container is a rice cooker, You can even cook delicious rice by heating to the core of the rice. Even during heat retention, rice is irradiated with far infrared rays from the inner pot in the same manner, so it is possible to keep heat with delicious rice forever. Also, in other cooking containers, heating and heat retention are good, and good cooking is possible.

Therefore, it has an effect of increasing the radiation amount of far-infrared rays, and cooking can be further improved.

調理用容器を提供することができる。In this embodiment, a white pigment such as titanium dioxide (TiO 2 ) or zinc oxide (ZnO) is added to the ceramic paint to make the ceramic coating 3 white, so that the inner wall of the container becomes white. If the color of the inner wall of the container is white, it can be recognized as dirt when dirt is attached, which is very convenient for cleaning. In addition, the cleanliness of appearance is improved, and it is possible to provide a cooking container that is clean and easy to clean.

できる。Further, in the present embodiment, the ceramic coating 3 can be made almost transparent by selecting uncolored ceramics such as Al 2 O 3 or SiO 2 as the ceramics of the ceramic coating, and the cooking container can be made. As a result, it is possible to realize a container whose inside wall is almost transparent. If the inside of the inner wall of the container is transparent, stains can be easily recognized as stains, which is very convenient for cleaning. In addition, the cleanliness of appearance is improved, and aluminum or stainless steel, which is the base material of the container, can be seen as it is, so that a clean cooking container can be provided forever.

The ceramic coating similar to the above is colored in a different color from the ceramic coating 3 other than the display body 5. That is, a coloring pigment or the like is added to the silicone resin coating material or the ceramic coating material forming the display body 5. By doing this, the display 5
