Description

  The present invention relates to an electromagnetic cooking pot.

  As a conventional container for electromagnetic cooking, a thin layer metal silver film formed by baking a silver paste containing metal silver powder on the surface of the bottom of a container made of earthenware (see, for example, Patent Document 1) Some have a heat generating layer formed by sintering metal powder mainly composed of conductive metal at the bottom of a container body made of a non-metallic material (for example, see Patent Document 2).

Japanese Patent No. 2653314 Japanese Patent No. 3871571

  However, the containers for electromagnetic cooking described in Patent Document 1 and Patent Document 2 have a problem that the thin metallic silver film and the heat generating layer are easily detached while being repeatedly used in the electromagnetic cooking device.

  The present invention has been made paying attention to such a problem, and an object thereof is to provide an electromagnetic cooking pot that can be used repeatedly and has high durability.

  To achieve the above object, an electromagnetic cooking pot according to the present invention has a heat generating layer made of conductive metal powder on the bottom inner surface of a pot main body made of ceramics, and the heat generating layer is formed on the inner surface of the pot main body. It is characterized by having a covering lacquer layer.

  The pot for electromagnetic cooking according to the present invention can be used for cooking by heating the heat generating layer containing conductive metal powder by an electromagnetic induction heating cooker. Since there is a lacquer layer covering the heat generating layer on the bottom inner surface of the main body, the lacquer has a heat resistance of about 700 ° C., and thus has high heat stability. For this reason, it can be used repeatedly and has high durability. The lacquer layer prevents the main body of the hook and the heat generation layer from being damaged by chopsticks and spatulas, and also has a good appearance.

  The pot for electromagnetic cooking according to the present invention is placed on an electromagnetic induction heating cooker and used for cooking rice, cooking sweet potatoes, and cooking curry, stew, boiled food, etc. can do. The conductive metal powder is made of, for example, iron powder, silver powder, gold powder, aluminum powder or the like.

  In the electromagnetic cooking pot according to the present invention, the pot body is formed by firing a ceramic material in which petalite and clay are mixed, and has a first lacquer layer on an inner surface of a bottom portion of the pot body. It is preferable that the heat generating layer is provided on the lacquer layer, the silicon resin layer is provided on the heat generating layer, and the second lacquer layer is provided on the silicon resin layer. In this case, since the pottery body is formed by firing a ceramic material in which petalite and clay are mixed, the pot body is not easily broken even if it is suddenly heated or cooled rapidly. Since the heat generating layer is provided on the first lacquer layer, the metal powder of the heat generating layer can be fixed on the first lacquer layer, and further, the metal powder of the heat generating layer can be fixed by the silicon resin layer. By uniformly spreading the metal powder of the heat generating layer, the entire kettle can be heated uniformly. Since the silicon resin also has a heat resistance of about 700 ° C., it has high heat stability. For this reason, it can be used repeatedly and has high durability.

  According to the present invention, an electromagnetic cooking pot that can be used repeatedly and has high durability can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an electromagnetic cooking pot according to an embodiment of the present invention.
As shown in FIG. 1, the electromagnetic cooking pot 1 has a pot body 2 and a lid 3.

  As shown in FIG. 1 (a), the pot body 2 is made of ceramic, has a downward convex shape with a circular horizontal section, and has an opening 21 at the top. The hook body 2 has a flat bottom 22, and has a flat lid mounting surface 23 at the periphery of the opening 21. The shuttle body 2 has a flange 24 that extends outward along the periphery of the opening 21.

  As shown in FIG. 1 (b), the pot body 2 is formed by firing a ceramic material obtained by mixing petalite and clay at 1200 ° C. The pot body 2 has a first lacquer layer 25a on the inner surface of the bottom 22, a heat generating layer 25b on the first lacquer layer 25a, and a silicon resin layer 25c on the heat generating layer 25b. A second lacquer layer 26 is provided on the silicon resin layer 25c. The first lacquer layer 25 a is formed by applying on the inner surface of the bottom portion 22. The heat generating layer 25b is formed by uniformly spreading a conductive metal powder on the first lacquer layer 25a. The metal powder is preferably composed of a mixture of iron powder, silver powder and gold powder. The silicon resin layer 25c is formed by coating on the heat generating layer 25b. The second lacquer layer 26 is applied to the entire inner surface of the hook body 2 from above the silicon resin layer 25c, and covers the heat generating layer 25b with the silicon resin layer 25c interposed therebetween. The pot body 2 has a lacquer layer 27 formed on the entire outer surface by applying lacquer.

  The lid 3 is formed by firing a ceramic material in which the same petalite and clay as the pot body 2 are mixed, and has a disk shape. The lid 3 has a peripheral edge that is smoothly bent downward, and has a handle 31 that protrudes upward in the center. The lid 3 closes the opening 21 on the hook main body 2, and the peripheral surface 32 fits the lid mounting surface 23 of the hook main body 2 exactly.

  In addition, in a specific example, the pot body 2 is for cooking rice, and its size is 2 cm, the inner depth is 14 cm, the radius is 7 cm, the inner depth is 3 cm, the inner depth is 15 cm, the radius Is 10 cm, 5 joints, the inner depth is 18 cm and the radius is 12 cm. The thickness of the pot body 2 is about 0.5 cm, the thickness of the heat generating layer 25b is about 0.02 cm, the thickness of the silicon resin layer 25c is 0.05 cm, the first lacquer layer 25a, the second lacquer layer 26, and the lacquer layer. The thickness of each 27 is about 0.03 cm.

Next, the operation will be described.
The electromagnetic cooking pot 1 can heat the heat generating layer 25b made of conductive metal powder by an electromagnetic induction heating cooker, and can be used for cooking. Since the inner surface of the bottom 22 of the pot body 2 has the second lacquer layer 26 that covers the heat generating layer 25b with the silicon resin layer 25c interposed therebetween, lacquer has a heat resistance of about 700 ° C., and thus has high heat stability. Moreover, since it has the heat generating layer 25b on the 1st lacquer layer 25a, the metal powder of the heat generating layer 25b can be fixed on the 1st lacquer layer 25a, and also the metal powder of the heat generating layer 25b by the silicon resin layer 25c. Can be fixed.

  Since the metal powder of the heat generating layer 25b is uniformly sown, the entire pot can be heated uniformly. In addition to the second lacquer layer 26, the first lacquer layer 25a, the lacquer layer 27, and the silicon resin layer 25c also have heat resistance of about 700 ° C., and thus have high heat stability, can be used repeatedly, and have high durability. Since the pottery body 2 and the lid 3 are formed by firing a ceramic material in which petalite and clay are mixed, the pot body 2 and the lid 3 are not easily broken even when heated suddenly or cooled rapidly.

  The second lacquer layer 26 applied to the entire inner surface can prevent the hook body 2 and the heating layer 25b from being damaged by chopsticks or a spatula. Further, since the second lacquer layer 26 is applied to the entire inner surface and the lacquer layer 27 is applied to the entire outer surface, the appearance is also good. The electromagnetic cooking pot 1 is placed on an electromagnetic induction heating cooker and can be used, for example, to cook rice as a rice cooking pot, to pour sweet potatoes, and to boil curry, stew, boiled food, etc. it can.

It is the (a) longitudinal cross-sectional view which shows the pot for electromagnetic cooking of embodiment of this invention, (b) The expanded sectional view of the bottom part.
