[Industrial Application Field] The present invention relates to a method for producing a cooking or eating container mainly made of non-magnetic metal that can be used in an electromagnetic induction cooking device (hereinafter simply referred to as an electromagnetic cooking device) for cooking. It is related to. [Prior Art] In recent years, electromagnetic cookers have become popular for cooking, and pots and kettles used for them have also appeared, but they are made of magnetic metals such as iron, nickel, and cobalt, as well as their respective materials. These include alloys (for example, stainless steel) and iron enamel, among which those that are used in practical use are almost limited to iron, stainless steel, and iron enamel. On the other hand, such iron products are heavy and inconvenient to handle, and there are problems with rust formation and transfer of metal particles to cooked foods, so they are not necessarily welcomed by ordinary households, and aluminum products and Copper products are still the mainstream due to their light weight and beauty, and many households have no choice but to use iron-based cooking vessels for use in the electromagnetic cookers. [Problems to be solved by the invention] Aluminum products are more popular than copper products because they are lightweight, beautiful, easy to use, and have high thermal conductivity. The disadvantage is that it cannot be used with electromagnetic cookers. The inventors of the present invention attempted to use an iron plate, which is a magnetic metal, on the outer surface of the bottom of a cooking container by simple spot welding, and found that it is possible to use it in an electromagnetic cooker. When such a cooking container is used not only in an electromagnetic cooker but also in a gas or electric stove, the bottom part may become distorted due to heating due to the bonding of dissimilar metals. It was discovered that the phenomenon of loosening and delamination of layers occurs, leading to a decrease in thermal efficiency.
As a result of continued testing and research to solve this problem, we have completed the present invention. [Means for Solving the Problems] The present invention is for joining a magnetic metal plate to the outer surface of the bottom of a container made of non-magnetic metal. The locking protrusion is welded to the magnetic metal plate, and the magnetic metal plate is provided with an insertion hole for the locking protrusion and a hole for absorbing distortion during heating, or After inserting the locking protrusion into the insertion hole or the dual-purpose hole, either by making it double as a strain absorption hole, or by caulking the protrusion or by spot welding, etc., the magnetic metal plate is attached to the container using the protrusion. It locks onto the bottom. In this case, a recess into which the magnetic metal plate to be joined is fit is formed on the outer surface of the bottom of the container, the locking protrusion described above is welded to the recess, and the magnetic metal plate is attached using the method described above. By locking, it is possible to lock more stably. In the present invention, the non-magnetic metal constituting the container is made of copper, aluminum, etc., which cannot originally be used in an electromagnetic cooker, and the magnetic metal plate is
Iron, nickel or its alloys (e.g. stainless steel)
can be mentioned. The locking protrusion formed on the outer surface of the bottom of the container is generally made of iron-based material.
Short rods of 10 mm or less and diameters of about 5 to 10 mm are preferably used, and these projections are dispersed in an appropriate number on the outer surface of the bottom of the container and welded by spot welding. In addition, the insertion hole or dual-purpose hole provided in the magnetic metal plate is arranged to match the locking protrusion,
When separately providing strain absorbing holes, they are provided as appropriate between such insertion holes. Such a magnetic metal plate is locked by inserting its insertion hole or dual-purpose hole into the protrusion provided in the container, and this is accomplished by caulking or welding the protrusion. As mentioned above, the following type of hole is recommended when the locking projection insertion hole and strain absorption hole are used both. That is, as shown in FIG. 4, the periphery of the hole 8 of the magnetic metal plate 7 is finished so as to expand in a tapered shape toward the bottom 9 of the container, and the top of the protrusion 10 is caulked or welded. This makes it possible to absorb the distortion caused by the difference in thermal expansion between the bottom part 9 of the bottom part 7 and the bottom part 9 of the bottom part 9 . Also, as shown in FIG. 5, the hole 12 of the magnetic metal plate 11
After forming a radial notch 13 around the radial notch and inserting the protrusion 14, the generation of distortion can be similarly prevented by locking the top of the protrusion to a portion of the magnetic metal plate other than the radial notch by caulking or welding. I can do it. [Function] As mentioned above, by providing a protrusion on the container and using this protrusion to lock the magnetic metal plate, sufficiently efficient heating is possible by electromagnetic induction heating. By attaching it to a magnetic metal plate and fixing it to the container, it is possible to reduce the difference in thermal expansion between different metals when the container is heated (when copper is used for the container body and a steel plate is attached to the bottom), the thermal expansion of copper is larger than that of iron, This strain absorption hole absorbs the strain caused by the iron plate not being able to follow the thermal expansion of the copper material, causing distortion in the copper material, thereby preventing distortion from occurring in the non-magnetic metal at the bottom. [Example] The present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the bottom of a container showing an example of manufacturing the container according to the method of the present invention, and FIG. 2 is a sectional view taken along line A-A' in FIG. In these, a recessed part 2 with a depth of 1 mm is provided on the outer surface of the bottom of a copper pot 1 with a bottom diameter of 200 mmφ, and this part is
Nine locking protrusions 4 with a diameter of 6.4 mm and a height of 7.2 mm were attached by spot welding. On the other hand, the iron plate 3 was provided with a hole 4' having a diameter slightly larger than that of the locking projection, and a strain absorbing hole 6 with a diameter of 5.0 mm. Then, by fitting the iron plate 3 into the recess 2, the protrusion 4 was inserted into the insertion hole 5, and then by pressing and caulking the protruding part of the protrusion 4, the iron plate was tightly fixed to the bottom of the copper pot. As shown in FIG. 3, the shape of the bottom of the pot before use of the pot obtained as described above was measured for surface unevenness in two directions, the X direction and the Y direction (direction of the arrow). The measuring device is a three-dimensional coordinate measuring machine 700 manufactured by Tokyo Seimitsu Co., Ltd.
-3B type was used. Tests were then conducted using this pot in the following order. 1) Water boiling test using an electromagnetic cooker. Two pots of water were placed in a pot and heated using an electromagnetic cooker. The time it took for the water to heat up to 90°C was measured. The water was heated for an additional 20 minutes, and this was repeated 10 times. 2) Water boiling test using a gas stove. A test similar to 1) was conducted using a gas stove. 3) Dry cooking test: Approximately 1 minute 30 minutes without adding contents using a gas stove
After heating for seconds, heating was stopped after the temperature of the measuring wall of the pot reached 200°C. The above tests were conducted, and the strain amounts (mm) in the X and Y directions during each test were compared using the pot before use as a reference, and the results are shown in Table 1 below.

According to the method of the present invention, a magnetic metal plate is locked to a non-magnetic metal container body using projections provided on the outer surface of the bottom of the container, which is originally lightweight and beautiful, but is not suitable for an electromagnetic cooker. It is excellent in that it allows hot copper or aluminum containers to be used in electromagnetic cookers. In addition, by providing holes in the magnetic metal plate for strain absorption, it absorbs the strain caused by the difference in thermal expansion between the non-magnetic metal container and the magnetic metal plate, making it suitable for current use in not only electromagnetic cookers but also gas stoves, electric heating stoves, etc. Sufficient durability can be ensured for any commonly used heating appliance for cooking. Further, since the bottom of the container has a double layer structure, the container can sufficiently withstand damage during handling, and there is little heat dissipation from this portion, and the present invention is excellent in these respects.
