Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic cooking container and a method for manufacturing the same, and more particularly, the invention relates to an electromagnetic cooking container that is placed on an electromagnetic cooker and is heated and kept warm by the electromagnetic induction action of magnetic lines of force generated from the electromagnetic cooker. This invention relates to a metal electromagnetic cooking container and its manufacturing method.

2. Description of the Related Art In recent years, a technology has been developed for heating and keeping cooking containers such as tableware warm by the electromagnetic induction effect of magnetic lines of force produced by an electromagnetic cooker. In other words, this technology uses alternating magnetic lines of force generated from an electromagnetic cooker to generate eddy currents in a container placed on the cooker, and the eddy currents and the electrical resistance of the container itself cause the electromagnetic cooker to generate no heat. It only generates heat in the container without causing any heat generation. Therefore, containers used for such electromagnetic cooking have strong magnetism that generates eddy currents due to the generation of alternating magnetic lines of force, and generate heat to a considerable temperature due to the synergistic effect of the eddy currents and electrical resistance. It is an essential condition that it be constructed of a material that has both conductivity to a certain degree. Therefore, conventionally, containers made of iron or iron enamel have been used as containers exclusively for electromagnetic cooking, and containers made of other materials have hardly been put to practical use as containers for electromagnetic cooking.

However, since such electromagnetic cooking containers are made of iron, it is not always easy to mold and process them, and therefore it is not possible to mold the container with various shapes and patterns, and the iron itself has its own characteristics. The image of the material was insufficient to match container products based not only on functionality but also on design.

Therefore, conventional electromagnetic cooking containers have a fatal drawback in that they cannot provide the same variety of designs as ordinary containers. Therefore, this drawback not only discourages consumers from purchasing, but also hinders the spread of the innovative technology of electromagnetic cooking.

In order to solve these problems, the present invention has been developed to provide an indispensable function for an electromagnetic cooking container, which is to generate heat due to the electromagnetic induction effect of magnetic lines of force generated by an electromagnetic cooker, and to replace the conventional iron electromagnetic cooking container. This is a completely new and useful electromagnetic cooking container that is easy to mold and process, and can be varied in shape and pattern to diversify the design. The purpose is to provide a method for producing the same.

In order to achieve such an object, the present invention provides an electromagnetic cooking container that is placed on an electromagnetic cooker and is heated and kept warm by the electromagnetic induction effect of magnetic lines of force from the electromagnetic cooker, the container body being made of non-ferrous metal. The electromagnetic body made of a r6-resistant material such as iron is provided on the contact surface of the container main body with the electric MW processing device or at a position facing the contact surface.

When an electromagnetic cooking container with such a configuration is placed on an electromagnetic cooker and an alternating current is passed through the coil of the electromagnetic cooker, alternating magnetic lines of force are generated and the contact surface or contact of the container body with the electromagnetic cooker is generated. An eddy current is generated in the electromagnetic body placed facing the surface, and this eddy current causes the electromagnetic body to generate heat due to the electric resistance of the electromagnetic body, and the heat of this electromagnetic body is transmitted to the container body, heating the container and keeping it warm. It will be done. In other words, it has become possible to construct the container body from a non-ferrous metal material that is easy to mold and process, while still providing the essential function of an electromagnetic cooking container, which is to generate heat due to the electromagnetic induction effect of magnetic lines of force.

Furthermore, the gist of the method for manufacturing an electromagnetic cooking container having the above configuration is that an electromagnetic body made of a magnetic material such as iron is placed in a mold, and then the electromagnetic body is melted at a temperature below the temperature at which it loses its magnetism. A container body is formed by pouring the non-ferrous metal material into the mold, and the electromagnetic body is integrated into the container body, and then the integrated container body and electromagnetic body are removed from the mold. .

In other words, the melting point of iron, which is an electromagnetic material, is approximately 1500.
The temperature at which magnetism is lost is extremely high at ~1,600 degrees, and the temperature at which magnetism is lost is also extremely high at approximately 800 to 850 degrees. Even if it is later poured into a mold, the electromagnetic material will not melt, and its magnetism will never be lost.

As described above, the present invention makes it possible to construct the container body from a non-ferrous metal material while still having the essential function of an electromagnetic cooking container, which is to generate heat by the electromagnetic induction effect of magnetic lines of force generated by an electromagnetic cooking device. This makes molding and processing easier than before, making it possible not only to maintain the material image of conventional iron containers, but also to create a variety of designs by changing the shape and pattern of the container body. This has resulted in the particularly remarkable effect of being able to achieve

As a result, there are great practical benefits in that it is possible to increase the consumer's desire to purchase, and it is also possible to spread the innovative technology of electromagnetic cooking more widely than before.

Furthermore, the manufacturing method of the present invention is a manufacturing method in which, as described above, an electromagnetic body made of a ferrous isomagnetic material is placed in advance, and then a non-ferrous metal material having a melting point below the temperature at which the electromagnetic body loses its magnetism is poured into the electromagnetic body. Therefore, not only is the work easier, but compared to conventional containers made of iron with a high melting point, the time required for manufacturing from the time the raw materials are melted is significantly shortened, resulting in a significant improvement in work efficiency. There are advantages that can be achieved.

EMBODIMENT OF THE INVENTION Hereinafter, embodiments of the present invention will be described according to an example shown in the drawings.

FIG. 1 is a longitudinal sectional view of an electromagnetic cooking container as an example;
FIG. 2 shows a bottom view, and in the figure, 1 shows the main body of the container as a sliding pot, which is formed into a substantially cylindrical shape with a bottom. Reference numeral 2 denotes a disk-shaped electromagnetic body made of iron, which is fitted and fixed into the recess 4 of the bottom surface 3 of the container body 1 via an adhesive.

When using the electromagnetic cooking container 5 having such a configuration, first place the container 5 on the electromagnetic cooker 6 and then apply an alternating current to the coil of the electromagnetic cooker 6 to generate alternating magnetic lines of force. However, due to these alternating magnetic lines of force, the electromagnetic cooker 6
An electromagnetic body 2 provided on the bottom surface 3 of the container body 1 to be in contact with the
An eddy current is generated in the electromagnetic body 2, and this eddy current causes the electromagnetic body 2 to generate heat due to the electric resistance of the electromagnetic body 2. Therefore, the heat of the electromagnetic body 2 is transferred to the container body 1, and the container 5 is heated and kept warm.

In addition, the container main body 1 is made of tin, which is a non-ferrous metal material, while still retaining the function that involves this series of actions, that is, the function that is essential for an electromagnetic cooking container to generate heat due to the electromagnetic induction action of magnetic lines of force. Since it has become possible to do this, it has become easier to mold and process, and the shape and pattern of the container 5 can be varied in various ways, making it possible to diversify the design.

Next, to explain the manufacturing method of the electromagnetic cooking container 5 having the above-mentioned structure, first, the disk-shaped electromagnetic body 2 formed in advance from iron is placed in the space of the mold 7 as shown in FIG. 3(A). Adhesive is applied to the surface of the electromagnetic body 2, which is arranged approximately in the center of the part 8. Next, as shown in FIG.
When cold tin is poured into the mold and left until the molten tin is assimilated, the mold is removed from the mold 7.
An electromagnetic cooking container 5 consisting of a container body 1 and six electric bodies 2 as shown in the figure is manufactured.

In this case, the iron that is the material of the electromagnetic body 2 is approximately 800° to 85°
Magnetism is lost at 0°, but since the shore point of tin, which is the material of the container body 1, is much lower at about 250° to 300°,
In the above manufacturing method, the function of the electromagnetic body 2 is never impaired. Moreover, the melting point is about 1500°~1
Compared to conventional containers made only of iron, which has an extremely high angle of 600°, the manufacturing time from melting the raw materials is significantly shortened.

As described above, in the above embodiment, the container body 1 can be made of tin, which is a non-ferrous metal material, so that the material image of the conventional electromagnetic cooking container can be maintained, and the design can be diversified. This not only increased consumers' desire to purchase, but also made it possible to spread the technology of electric cooking even more widely.

In the above embodiment, a recess 4 is provided on the bottom surface 3 of the container body 1.
are formed, and the electromagnetic body 2 is fitted and fixed in the four parts 4, but it may also be fixed directly to the bottom surface 3 without forming the recess 4, as shown in FIG. 4, for example. In addition, in all of these embodiments, the electromagnetic body 2 is provided on the bottom surface 3 of the container body 1 so that the electromagnetic body 2 is in direct contact with the electromagnetic cooker 6. Although the electromagnetic body 2 does not necessarily have to be in direct contact with the electromagnetic body 2, as shown in FIG. In addition to being able to be buried in the bottom of the container body I, it may also be provided on the inner peripheral surface side of the container body I as shown in FIGS. 6 and 7. In short, it is sufficient that it is provided on a contact surface with the electromagnetic cooker 6 or facing the contact surface.

Furthermore, the material of the container body 1 may also be aluminum, copper, etc., in addition to the tin base in this embodiment.

Further, the material of the electromagnetic body 2 is not limited to the iron used in this embodiment, but any material may be used as long as it has magnetism and conductivity to the extent that heat can be generated by the electromagnetic induction action of magnetic lines of force.

Further, although the container body 1 in this embodiment is manufactured as a pot, the type of pot, kettle, plate, sake cup, etc. is not a matter of concern, and therefore the shape of the container body 1 is also never a matter of concern. do not have.

Similarly, the shape of the electromagnetic body 2 is by no means limited to this embodiment.

Further, in this embodiment, the electromagnetic body 2 is fixed to the bottom surface 3 of the container body 1 via an adhesive, but the means for fixing the electromagnetic body 2 to the container body 1 is by no means limited to adhesive.

All modifications may be made within the intended scope of the invention.
