Description

[Detailed Description of the Invention] The present invention relates to improvements in cooking pots such as frying pans, egg fryers, and okonomiyaki grill plates.

Conventional cooking pots of this kind are usually constructed of steel plates or stainless steel plates, so they have the disadvantage that food tends to burn even if a small amount of cooking oil is applied to the cooking surface. Therefore, recently there have been many cases where a thin layer of fluororesin is applied to the cooking surface of the main body made of metal to prevent burning.
A thin layer of fluororesin does not have a very high heat resistance or surface hardness, so it has the drawbacks of being careful in handling and having poor durability.

The present invention was completed with the aim of creating a cooking pot that does not have the above-mentioned drawbacks.As shown in the illustrated embodiment, the present invention has an enamel layer 2 on which countless fine boron nitride particles 1 are scattered. is layered on the cooking surface of the metal main body 3. In addition, 4 in the figure is an aluminum plating layer that is layered on the main body 3 as necessary in order to firmly integrate the enamel layer 2 to the cooking surface of the main body 3 when the metal main body 3 is made of iron plate. .

This configuration consists of a metal main body 3
The cooking surface such as the inner bottom surface of the main body 3 is covered with an enamel layer 2 layered on the main body 3, and the surface of the enamel layer 2 has countless fine boron nitride particles 1 scattered thereon. Therefore, it has an extremely high surface hardness and a heat resistance temperature of about 600 to 700 degrees Celsius, so there is almost no deterioration, making it practical as it is also desirable for decoration. Nitrogen boron particles 1
Since it has excellent mold release properties, it properly prevents the food to be cooked from burning. Furthermore, the countless boron nitride particles 1 are uniformly scattered on the surface of the enamel layer 2 with their bases embedded in the enamel layer 2, which is easily fixed and integrated with the metal main body 3. There is no risk of peeling off due to friction during cleaning, and it has the advantage of being easy to handle and long-lasting. However,
To manufacture such a cooking pot, 0.5 to 20 parts of boron nitride particles with a particle size of about 100 μm or less, 45 to 55 parts of water, clay, potassium chloride, and carbonate are added to 100 parts of enamel frit by weight. After adding an appropriate amount of an electrolyte such as potassium and stirring well, the main body 3 is glazed by a normal glazing method, dried and fired to form an enamel layer 2, so that many of the boron nitride particles 1 are raised from the surface side, or It can be easily obtained by applying a normal enamel glaze to the main body 3 and then spraying the boron nitride particles 1 with a powder gun or the like before drying and firing after drying, so mass production is easy and can be provided at low cost. Note that the area ratio between the boron nitride particles 1 and the exposed portion of the enamel layer 2 on the surface of the enamel layer 2 is not particularly limited;
If the ratio of 0.7% to 24% is economical,
This is preferable from the standpoint of releasability.

Therefore, the present invention has great practical value as it eliminates the drawbacks of conventional cooking pots of this type.
