Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Field of Industrial Application) This invention relates to a pot for a rice cooker used when cooking rice in a rice cooker.

(Prior Art) When cooking rice with a rice cooker, first a desired amount of rice and an amount of water corresponding to the amount of rice are placed in a rice cooking pot. This pot is then inserted into the main body of the rice cooker, and the pot is heated by a heat source such as an electric heater or a gas burner to cook rice.

A rice cooking pot is made of a material such as aluminum, which is deep-drawn and press-formed into a cylindrical shape with a bottom.The inner surface of the pot is made of a material such as aluminum to make it non-adhesive and corrosion-resistant. It is equipped with a coating film made of fluororesin, and a water level display scale placed on a part of the main surface of the pot to indicate the amount of water to be stored.

As a water level display scale, as shown in FIG. 5, a convex portion 3 is formed by stamping from the outer circumferential side on the circumferential surface of the pot main body 2, the inner surface of which is coated with a coating film 1. As shown in FIG. 6, the convex portion 3 is used as a water level display scale, and as shown in FIG. Convex part 3
, and further peel off the coating film 1 on the surface of the convex portion 3 to expose the convex portion 3 directly on the inner peripheral surface side of the pot main body 2, and use the convex portion 3 as a water level display scale, Alternatively, as shown in FIG. 7, after press-forming the pot main body 2, stamping is applied from the inner peripheral side of the pot main body 2 to form a recess 4 on the inner peripheral surface, and paint is applied inside the recess 4. After that, a coating film 1 made of transparent fluororesin is applied to the entire inner surface of the pot body 2, and a mark 3 having a color tone different from that of the material of the pot body 2 is formed with the paint in the recess 4. It is known that the water level display scale is 3.

(Problem to be Solved by the Invention) However, in the case shown in FIG. The color tone is no different from the overall inner surface of the pot main body 2, and therefore, it is difficult to visually distinguish the outline of the convex portion 3 (water level display scale) and its placement position. In the case shown in FIG. 6, since the convex portion 3 is exposed on the inner circumferential side of the pot main body 2, a difference occurs between the color tone of the convex portion 3 and the color tone of the inner surface of the pot main body 2 that appears through the coating film 1. This has the advantage that the location and outline of the protrusion 3 can be identified relatively clearly, but the coating film 1 must be peeled off from the portion corresponding to the protrusion 3 one by one, making the post-processing troublesome and time-consuming. Moreover, since the convex portion 3 is exposed to the outside by peeling off, there is a problem that non-adhesiveness and corrosion resistance are lost in this portion. The mark 3 in FIG. 7 has the advantage of being colored so that its placement position and outline can be clearly identified, as well as maintaining good non-adhesiveness and corrosion resistance. However, the recess 4 has a narrow area. Since the coating film 1 must be applied to the entire inner surface of the pot main body 2 after application of the paint, the entire process is complicated and the work is considerably troublesome, reducing manufacturing efficiency. There is a drawback that the cost is high.

This invention was made with attention to these points, and its purpose is to be able to clearly identify the placement position and outline of the water level display scale with a simple structure, and to be non-adhesive and non-adhesive. To provide a pot for a rice cooker that can maintain good corrosion resistance and can be manufactured easily and efficiently.

[Structure of the Invention (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a pot body, a material for the pot body applied to a part of the inner circumferential surface of the pot body, and A printed film of different colors, a fluororesin coating film applied to the entire inner surface of the main body of the pot, including this printed film,
A water level display scale formed by stamping on the main surface of the pot, the printed film having a certain extent larger than the outer shape of the water level display scale, and the water level display scale within the area of the printed film. It is arranged so that at least a portion of it can be accommodated.

(Function) In such a pot, since the printed film has a different color tone from the material of the main body of the pot, it is possible to immediately determine where on the inner surface of the main body of the pot the printed film is placed based on the difference in color tone. and can be clearly recognized.

Since the water level display scale is provided on the printed film, it is possible to clearly determine the location of the water level display scale based on the printed film.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Figure 3 shows the overall appearance of the rice cooker pot 10.

It consists of a scale 14. The printed film 1
2 is formed of ink of a color different from that of the pot main body 11, for example, white, and has a certain extent larger than the overall external shape of the water level display scale 14, and the water level within the area of this printed film 12 is It is provided so that the entire display scale 14 is accommodated.

Describing the manufacturing process of this pot 10, first a printing film 12 is applied to a part of one side of a circular flat plate material, and then a coating film 13 of transparent fluororesin is applied to the entire one side of this material.

Then, this material is processed into a bottomed cylindrical shape by deep drawing press forming so that the coating film 13 is on the inner surface.

Through this processing, the material becomes a pot main body 11, a printed film 12 is disposed on a part of the inner peripheral surface of the pot main body 11, and the entire inner surface of the pot main body 11 is covered with a coating film 13. Thereafter, in a portion corresponding to the printed film 12, a stamp is applied from the outer circumferential side of the pot main body 11 to form a water level display scale 14 that projects toward the inner surface of the pot main body 11.

In such a pot 10, the printed film 12 is attached to the pot main body 11.
Since the color tone is different from that of the material, it is possible to immediately and clearly recognize where on the inner surface of the pot main body 11 this printed film 12 is placed based on the difference in color tone. Since the water level display scale 14 is provided on the printed film 12, the position of the water level display scale 14 can be clearly determined based on the printed film 12. Since the water level display scale 14 is engraved so as to protrude from the inner surface of the pot main body 11, the outline of the water level display scale 14 can be clearly recognized and the amount of water to be stored in the pot 10 can be accurately determined without error. can be measured.

In manufacturing this pot 10, a printed film 12 and a coating film 13 are applied to one side of a flat material, and after this material is press-molded to form the main pot body 11, the printed film 12 is applied from the outer circumferential side. Since it is only necessary to engrave the water level display scale 14 on the water level display scale 14, the work is easy and can be manufactured efficiently. Since the water level display scale 14 formed on the inner surface of the pot main body 11 is covered with the printed film 12 and the coating film 13, the non-adhesiveness and corrosion resistance of this part are maintained as well as other parts. be able to.

In the above embodiment, the entire water level display scale 14 was provided within the area of the printed film 12, but as shown in FIG. 4, a part of the water level display scale 14 has a certain extent. The printed film 12 may be placed within the area of the printed film 12 and other parts may protrude from that area. The position of the water level display scale 14 can be clearly identified. Alternatively, the water level display scale 14 may be engraved from the inner periphery of the pot main body 11 so as to protrude toward the outer periphery.

In addition, multiple printed films of different colors are lined up in the circumferential direction on the inner peripheral surface of the main pot, and multiple water level display scales corresponding to rice cooking menus such as white rice, brown rice, and rice are formed on these printed films. You may also do so.

Effects of the Invention As explained above, according to the present invention, the placement position and outline of the water level display scale can be clearly identified, and therefore the water amount can be measured easily, efficiently and without error, and the pot-based It has the advantage of maintaining good non-adhesiveness and corrosion resistance over the entire inner surface, and can be manufactured easily and efficiently.
