[0006] In the aluminum foil takoyaki maker in the above document, the heating part of the household heating appliance is circular, while the recesses are arranged on a roughly square plate, so the shapes do not match, resulting in areas that are heated strongly and weakly, which makes it easy for uneven cooking to occur.In addition, the shape of the recesses is shallow compared to the diameter, which makes it difficult to make beautiful spherical takoyaki. [Means for solving the problem]

[0007] Therefore, this invention aims to make the outline of the takoyaki maker disk-shaped so that it matches the heating area of ​​the heating device, thereby uniformly transferring heat and preventing uneven cooking.

[0008] That is, the takoyaki maker of the present invention is a takoyaki maker made of aluminum foil with a disk-shaped outline, and is characterized in that it comprises a plate portion with a disk-shaped outline and a plurality of hemispherical depressions (also simply called depressions) formed on the plate portion, the diameter of the depressions being 30 mm or more and 60 mm or less, the depth of the depressions being 20 mm or more and 40 mm or less, and the thickness of the aluminum foil being 50 μm or more and 250 μm or less. [Effects of the Invention]

[0009] By making the outline of the takoyaki maker disc-shaped and matching it to the heating area of ​​a household heating appliance, uneven heating is reduced, making it easier to cook the takoyaki evenly.

[0010] Furthermore, since the forming depth is sufficient relative to the diameter of the plurality of hemispherical recesses, it is possible to make spherical takoyaki. In addition, to ensure sufficient strength and enable the formation of hemispherical recesses of the depth described above, the takoyaki maker is made of aluminum foil with a thickness of 50 μm to 250 μm.

DETAILED DESCRIPTION OF THE INVENTION

[0012] As shown in FIG. 1, the takoyaki maker 100 of the present invention comprises a plate portion 110 with a disk-shaped outline and a plurality of hemispherical recesses 120 formed on the plate portion. The diameter of each hemispherical recess 120 is 30 mm to 60 mm, and the depth of each hemispherical recess 120 is 20 mm to 40 mm. This shape allows for the creation of spherical takoyaki. Note that, in this invention, "takoyaki" does not necessarily refer to dishes containing octopus meat as a filling, but also includes dishes containing other well-known fillings such as konjac, squid, rice cakes, kimchi, cheese, meats such as sausage, bacon, and beef tendon, shellfish such as scallops and clams, and fish meats such as salmon and chikuwa. "Takoyaki" using such fillings as substitutes for octopus are also customarily made in various households under the name "takoyaki," and the uses of the takoyaki maker of the present invention encompass these "takoyaki without octopus" dishes.

[0013] The multiple hemispherical recesses 120 are preferably arranged in multiple rows at equal intervals, as shown in Figures 2 and 3. This arrangement ensures that heat is conducted uniformly to each recess, preventing uneven cooking of takoyaki. "Arranged in multiple rows" means that, when the plate is viewed from above, two or more hemispherical recesses are arranged in a certain direction and in a direction that forms a right angle or 60 degrees with that direction in the plane. For example, they may be arranged in a 2x2, 3x3, 4x4, or honeycomb pattern.

[0014] Furthermore, when the hemispherical recesses are arranged at equal intervals, there is a certain amount of plate portion between adjacent recesses, which ensures strength and suppresses deformation.

[0015] The bottom of the hemispherical recess 120 has a hemispherical shape as shown in Fig. 4. The hemispherical shape allows the takoyaki batter to rotate smoothly and form into a uniform sphere when it is turned over.

[0016] The value obtained by dividing the depth 210 of the hemispherical depression by the diameter 200 is preferably between 1 / 2 and 1. If it is less than 1 / 2, the depth is shallow compared to the diameter of the hemispherical depression, and the takoyaki will be flattened when cooked. If it is greater than 1, it will be difficult to form, the aluminum foil will tear, and the yield will be poor. Even if it can be formed without tearing, the depth will make it difficult to rotate the takoyaki.

[0017] The takoyaki maker of this invention is made of aluminum foil. Aluminum is lightweight, easy to mold, and has good thermal conductivity, making it a suitable material for cooking utensils.

[0018] The aluminum foil has a thickness of 50 μm or more and 250 μm or less. It is important that the thickness of the aluminum foil is within this range in order to maximize the thermal conductivity and enable uniform heating while ensuring the mechanical strength of the takoyaki maker. If the aluminum foil is too thin, it is prone to deformation and breakage, and if it is too thick, the heat transfer rate decreases.

[0019] The composition of the aluminum foil is not particularly limited, but may be selected appropriately from industrially pure aluminum or aluminum alloys such as 1N30 material, 3003 material, 8021 material, and 8079 material specified in JIS H4160-1994. In addition, from the viewpoint of formability, a soft material is preferable.

[0020] In order to form such hemispherical recesses, the aluminum foil is preferably an aluminum alloy foil that has excellent formability.

[0021] For example, it is preferable that the takoyaki maker contains 0.1% to 3.0% by mass of manganese, 0.05% to 0.9% by mass of silicon, 0.1% to 1.3% by mass of iron, and 0.01% to 0.2% by mass of copper, with the remainder being aluminum. This composition improves corrosion resistance and processability, while maintaining the high thermal conductivity of aluminum and achieving both durability and uniform heat transfer performance for the takoyaki maker. Specifically, manganese imparts mechanical strength, formability, heat resistance, and corrosion resistance. Silicon improves mechanical strength and formability, while iron enhances mechanical strength and formability. Copper contributes to improving mechanical strength.

[0022] The outer edges of the takoyaki maker may be formed with a rim, which not only prevents cuts at the edges but also suppresses deformation due to external forces.

[0023] The anti-adhesion layer 220 may be formed on the surface of the hemispherical recess as shown in Figure 4. There are no particular restrictions on the material of the anti-adhesion layer 220 as long as it has anti-adhesion and release properties and is hygienically permitted for use in cooking utensils, but fluororesin, silicone resin, etc. are preferably used. This anti-adhesion layer has low surface energy, making it difficult for batter to adhere to it, making it easier to rotate and remove the takoyaki.

[0024] The anti-adhesion layer is also designed to minimize the reduction in thermal conductivity by forming a uniform, thin film on the surface of the recesses. Specifically, the thickness is preferably controlled to about a few micrometers, and the design is such that the increase in thermal resistance during heating is minimized.

[0025] A heat-resistant layer (not shown) may be formed on the surface of the takoyaki maker. The heat-resistant layer is formed by applying a heat-resistant coating to the surface of the aluminum foil, and the heat-resistant layer is a coating made of a heat-resistant inorganic or organic material. Examples include silicone resin, fluororesin, and composite materials of ceramics and resin. This heat-resistant coating can improve the heat resistance and corrosion resistance of the takoyaki maker.

[0026] The heat-resistant coating film is preferably formed to a thickness of several micrometers, and while ensuring thermal conductivity, it also exhibits sufficient mechanical and chemical protective functions.

[0027] The outline of the takoyaki maker 100 is disk-shaped, and as shown in Figure 5, it is designed with dimensions and a shape that match the heating area 150 of a home heating appliance. By having such a shape, and by matching the shape of the takoyaki maker with the range of the heating area, uneven heating can be minimized and uniform heat can be supplied to the entire surface.

[0028] Next, we will explain how to use the takoyaki maker. First, pour the takoyaki batter into the hemispherical recess of the heated takoyaki maker. At this time, pour in an amount of batter that is flush with the plate of the takoyaki maker, i.e., an amount that is approximately equal to the internal volume of the hemispherical recess.

[0029] Next, after baking for a predetermined time, the dough is flipped upside down. At this time, the hemispherical portion formed on the bottom (inner surface) of the hemispherical recess maintains its shape and appears as the upper portion. Meanwhile, the unhardened dough at the top before flipping is restricted by the shape of the inner surface of the hemispherical recess during the flipping process, forming the spherical bottom portion after flipping. In other words, the portion of the dough poured into the hemispherical recess that has baked and hardened into a hemispherical shell shape is inverted while maintaining its shape, while the remaining portion forms part of the spherical shape or is incorporated into the interior of the spherical shape.

[0030] Furthermore, you can rotate the dough by about 90 degrees in any direction multiple times, which will make the takoyaki almost spherical.

[0031] Using the takoyaki maker of this invention, you can make spherical takoyaki by simply flipping the octopus batter placed in the hemispherical recess several times. Furthermore, since the takoyaki maker is disc-shaped and matches the shape of the heating device, it can be cooked evenly. Therefore, anyone, even if they are not an expert, can easily make a large number of spherical takoyaki.

[0032] In this invention, the takoyaki plate is not limited to the above-mentioned form, and the function and effect of this invention can be achieved by Various modifications can be made as long as they are effective. [Industrial Applicability]

[0033] The takoyaki maker of this invention is particularly suitable for making takoyaki using a household heating cooker, and does not require an expert, allowing anyone to easily make a large number of spherical takoyaki. [Explanation of symbols]
