Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate for a rice cooker and a method for manufacturing the plate, and has a beautiful appearance as a plate used for a rice cooker for offering Buddhist rice in front of a Buddhist altar. (EN) A product that is excellent in retained durability and that can be safely used by sufficiently eliminating sharpness, and that the product of the platter is relatively simple and suitable and can be obtained at low cost. It is intended to obtain a possible manufacturing method.

[0002]

2. Description of the Related Art A rice cooker has been used for a long time as a tool for serving Buddhist rice in front of the Buddha. As it has been done, simply by adding Buddhist rice, not only at the time of inclusion and pre-French memorial service, but also withdrawal after completion of the service and discharge of Buddhist rice, as well as all subsequent operations such as cleaning and wiping. Since it is necessary to always handle the entire rice cooker, it is necessary to use a platter and especially to form a gripping protrusion on the peripheral side of the platter to facilitate the loading / unloading operation of the dish. On the human side, a proposal such as Japanese Utility Model Publication No. 59-5421 (Japanese Utility Model Publication No. Sho 53-75300) was made, and the product has been widely marketed.

[0003]

According to the prior art as described above, only the serving plate is handled particularly for the handling after the memorial service, and the handling such as the taking out of the French meal and the washing and wiping after the taking out are small. Although it has the merit that it can be carried out only with the dish part body, on the other hand, it is handled for the small dish part body only, so it should be handled only with the fingertips, especially the platter plate is as thin as possible and corrosion resistant and aesthetic. Since it is a metal material excellent in durability and strength, etc., it has some disadvantages.

That is, the applicant of the present invention has produced and sold the above-mentioned platter for many years. The platter is filled with hot rice and is always exposed to a humid condition. Moreover, since it should be set in a state where the presence of the platter can not be visually recognized even if it is set in the recessed portion at the top of the rice cooker, it is preferable that the metal material is made of steel or aluminum based In general, it is not suitable for a body that requires semi-permanent use for at least several years or more, preferably 10 years or more.
Further, even in the case of an iron-based material, it is not preferable even if it is plated in the process because of its glossiness and generation of rust.

Therefore, the present inventors have made extensive studies on the use of a stainless material, but in this case, it is necessary to use a thin layer plate material having a thickness of 0.5 mm or less, and the inclusion Where the plate should be fitted so that there is not much gap with the recessed portion of the top of the rice cooker,
The removal and other handling of the platter that has been fitted in this way is done mainly with the fingertips, and the removal operation, cleaning, and
It is highly likely that the fingertips will be damaged during the cleaning operation. In other words, the stainless material can obtain sufficient corrosion resistance and strength in a thin layer, but in the thin stainless member, sharpness remains at the cutting edges, etc. When operating, the sharpness of the cut edge damages the operating fingertip and the like.

Therefore, various investigations have been made to eliminate the sharpness at the cutting edge of the platter, but since the stainless steel material has high hardness and strength, the cutting edge should be rounded. Processing is not easy and requires a great number of man-hours, which is an industrial disadvantage.
Therefore, there is no choice but to leave some possibility of damaging the fingertips during handling.

[0007]

As a result of repeated studies on solving the above-mentioned problems in the prior art, the present invention uses a specific stainless steel plate and has a structure different from that of the conventional platter. By adopting the above-mentioned method, the above-mentioned problems can be solved accurately, and at the same time, the above-mentioned plate can be obtained relatively easily and at low cost, and is as follows.

(1) A dish-shaped body which is detachably fitted into a housing portion formed by recessing the top surface of a French rice cooker,
The holding portion is formed of a stainless steel plate having a thickness of 0.25 to 0.38 mm, a grip portion is provided on one side of the dish, and a coating layer is attached to the grip portion and the top edge of the accommodating portion is formed. A plate for a rice cooker, characterized in that an engaging edge circularly fitted to be fitted to is formed by folding back the stainless steel plate.

(2) A dish-shaped throttle portion is formed on a stainless steel plate having a thickness of 0.25 to 0.38 mm, and a peripheral portion of the dish-shaped throttle portion is formed by cutting a peripheral portion of the grip portion. In addition, notches are formed on both sides of the grip portion, then the outer peripheral portion of the peripheral portion other than the grip portion is bent in the inner diameter direction, and the bent portion is pressure-welded in multiple layers and then vacuum annealed. Moreover, a method for manufacturing a dish tray for a French rice cooker, characterized by comprising coating a coating layer on the grip portion.

[0010]

[Function] A dish-shaped body which is detachably fitted into a housing formed by recessing the top surface of a French rice cooker and has a thickness of 0.25.
Since it is formed from a stainless steel plate of ~ 0.38 mm, it is possible to obtain durability while ensuring proper formability. If the thickness is less than 0.25 mm, the strength is insufficient even if it is made of stainless steel, and it will be deformed by depression with the fingertip, so it should be used for more than 10 years. It is not suitable as a serving dish for rice cookers intended for. On the other hand, if the thickness exceeds 0.38 mm, the diameter is generally 50-6.
It becomes difficult to form and manufacture the small-sized platter for general households having a size of about 0 mm, and it is particularly difficult to properly carry out the narrow flattening polymerization forming by folding and folding adopted in the present invention. Becomes

In the above-mentioned rice cooker, the engaging edge which is circularly fitted to fit the top edge of the accommodating portion is formed as a folded back portion of the stainless steel plate. Precisely eliminates the possibility of fingertips directly contacting the cutting edge at the periphery of the platter that was obtained by cutting out a thin layer material, and the rounded folded-back portion will be positioned to project. Therefore, the possibility of damaging a finger or the like at the portion is sufficiently eliminated. The thin layer of the material is sufficiently covered, which is aesthetically pleasing.

Further, since the folded-back bent portion as described above is provided on the peripheral side of the plate-shaped portion so as to surround the plate-shaped portion, the strength or the shape of the plate is sufficiently stabilized, and the attachment / detachment to / from the rice cooker can be improved. Since it can withstand handling sufficiently, even if the thickness of the stainless steel plate that is the material is reduced, effective strength is ensured, and the stainless steel material also has sufficient corrosion resistance. The thin layer facilitates plate-shaped molding and folding back, and facilitates manufacturing.

Moreover, a grip portion is provided so as to protrude from a part of the engaging edge,
The sharpness at the edge of the fingertip gripping part when the gripping part is covered with the coating film layer is properly encapsulated by the coating film layer when it is attached to or detached from the rice cooker. Remove damage from fingertips, etc. At the same time, the coating layer is layered on the front and back sides of the gripping portion, so that a thick feeling is formed even when the gripping portion is a single layer, and a heavy feeling is also formed in this portion.

A plate-shaped throttle portion is formed on a stainless steel plate having a thickness of 0.25 to 0.38 mm, and a peripheral portion of the dish-shaped throttle portion is formed by cutting a peripheral portion of the plate-shaped throttle portion. By forming notches on both sides of the grip portion, a general shape of the dish tray for a French rice cooker is formed and a shape such as bending and crushing processing for the peripheral portion other than the grip portion can be effectively performed. .

A sharp end is obtained by bending the outer side portion of the peripheral portion other than the grip portion in the direction of the inner diameter of the one obtained as described above, further pressing the bent portion in multiple layers and then vacuum annealing. A preferable bent state in which the edge portion is wound on the inner diameter side is formed, and what remains in the multi-layered bent portion such as working oil used in such working is appropriately removed by the vacuum annealing treatment.

As described above, by covering the gripping portion which is formed by being rolled into the inner diameter side and protruding from the peripheral edge portion, the coating layer is covered so that the sharpness of the peripheral edge portion of the gripping portion is covered. And a solid feeling is formed in the portion.
