可能である。 Traditionally, pots, frying pans, and other containers have been widely used as cooking containers used to boil, boil, or bake cooking ingredients, but electromagnetic cookers, which generate electric current magnetically from a power supply, An electromagnetic induction heating type cooker uses a coil to generate magnetic lines of force on the surface of the top plate to generate heat in the pot itself, which is placed on the top plate, and uses that heat to cook food. It has recently become popular due to its many advantages, such as: no combustion gas is generated, so there is no risk of fire, the air in the room can be kept fresh, and the bottom of the pot will not get dirty due to flames. Cooking containers that can be used include enamel iron pots, iron frying pans, 18 chrome stainless steel pots, iron plates, etc. The entire container is made of magnetic material, and aluminum pots and other non-magnetic materials cannot be used. be.
しかしながら、電磁調理器に従来の鉄ホーロー

不具合もある。 However, when using a conventional iron enamel pot with an induction cooker, it is heavy and difficult to handle, and when using an iron frying pan or other iron frying pan, it tends to overheat locally, making it unsuitable for ``grilling'' cooking and making it difficult to handle for a long time. There is a problem that it cannot withstand use for a long time and at high temperatures. Moreover, it also has the problem of being easily rusted.

つている。 By the way, as mentioned above, the second bottom portions 5a to 5
To form f, methods such as casting, press fitting, welding, caulking, thermal spraying, brazing, etc. can be freely adopted singly or in combination, and which method is selected depends on the overall shape of the container body 1, Although it is determined appropriately depending on the size, especially the shape and size of the bottom part 2, it is necessary to reliably integrate the first bottom part 4 and the second bottom part 5, regardless of the difference in their materials. There is. Figures 4 to 6 each show an example, in which the second bottom parts 5a to 5d, 5g, and 5h are adjusted to a position B that is slightly recessed inward from the outer surface position A of the first bottom part 4. It has been done. Distance l between positions A and B
is the thickness t1 of the second bottom portions 5a to 5d, 5g, and 5h.
is 0.5 to 2.5 mmt , and the thickness of the portion 7 of the container body 1 where the second bottom portions 5a to 5d, 5g, and 5h are provided is t2
When it is 1.0 to 5 mmt , it is preferable to set it to about 0.05 to 2 mm, and by balancing these sizes, good heat uniformity can be expected, and the above-mentioned integration can be further achieved. . That is, the second part is made of magnetic material and has a size of 0.05 to 2 mm.
The first bottom surface portion 4 protruding from the bottom surface portions 5a to 5d, 5g, and 5h softens distortion caused by thermal expansion due to the difference in material between magnetic material (for example, iron material) and aluminum alloy, and the second bottom surface portions 5a to 5d. , 5g, and 5h from being easily peeled off from between the first bottom part 4, and the protrusion of 0.05 to 2 mm allows the second bottom part to be easily separated when this cooking container is placed on an electromagnetic cooker (not shown). This also prevents the parts 5a to 5d, 5g, and 5h from coming into contact with the electromagnetic cooker and being damaged during long-term use. In this way, in the embodiment shown in FIG.
By protruding from g and 5h by a distance l, the occurrence of distortion is absorbed and the integration of both is further improved, and the embodiment shown in FIG. 5 further improves the integration. That is, by "caulking" the protruding first bottom surface part 4 to form a locking part 8 at the end thereof, the second bottom surface parts 5a to 5d, 5g, 5
h In other words, the magnetic materials 3a to 3d, 3g, 3h
I am trying to fix it. In addition, the same action and effect as "caulking" can be achieved by pressing the parts of the container body 1 between the magnetic materials 3d by pressing if the ends of the magnetic materials 3d are rounded as shown in FIG. Locking part 9
It can be obtained by forming . In the embodiment shown in FIG. 6, the first bottom part 4 protrudes by a distance l like the embodiments shown in FIGS. 4 and 5, but in addition, a ceramic coating is applied to the second bottom part 5. A layer 10 is formed to further protect the second bottom portion 5.

A mesh-like second bottom part 5i is arranged on the bottom part 2 of the
is formed. In order to form such a mesh-like second bottom part 5i, "casting" is suitable.
As shown in the figure, the mesh body 11 is placed in the cavity 14 between the upper and lower molds 12 and 13.
By pouring molten aluminum or aluminum alloy into the container body 1, a magnetic material 3 is formed on the outside of the bottom 2 of the container body 1.
It is sufficient if the mesh body 11 made of

も抑制できるという優れた効果がある。 As explained above, the present invention provides a magnetic material partially on the outside of the bottom of a container body made of aluminum alloy, leaving the bottom surface of the container body, and forming a bottom surface made of the magnetic material there. The bottom part made of magnetic material is provided so that its outer surface is retracted inward from the outer surface position of the bottom part of the container body, so that the bottom part of the container body The magnetic material on the outside is wedged into the container body, making it possible to further improve its integration and obtain a wide electric heating area.Moreover, the part where the magnetic material is not exposed, that is, the aluminum or aluminum alloy of the container body, remains as it is. The exposed bottom part exhibits gloss under the pattern created by the combination with the bottom part made of magnetic material, which increases the design value of the cooking container. By making the bottom part slightly protrude from the bottom part made of magnetic material, the protruding part absorbs the distortion caused by thermal expansion due to the difference in materials, making it easier to prevent the magnetic material from peeling off. This has the excellent effect of preventing damage to the bottom surface made of magnetic material.
