Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] Generally, a resin coating of non-affinity Teflon (trade name: ethylene tetrafluoride resin) is formed on the inner surface of an inner pot of an electric rice cooker. . The resin coating formed on the inner surface prevents "burning" and corrosion of the cooking material in the inner pot, which is caused by the cooking of cooked rice.

On the other hand, a scale is provided on the inner surface of the inner pot, which indicates an appropriate water level for the volume of rice to be cooked. The number attached to the water level scale indicates the number of rice cups measured with a measuring cup. Rice is then cooked after the ground rice is transferred to an inner pot and water is filled to a level corresponding to the number of cups of rice.

The present invention relates to a cooking container such as an inner pot of an electric rice cooker, and particularly to cooking provided with an inner surface coated with a resin and provided with a scale indicating a water level, a numerical value, or a character or symbol indicating a type of cooking. The present invention relates to the improvement of containers for containers.

[Prior Art] FIG. 7 is an explanatory view of the structure of a conventional apparatus, in which an inner pot for an ordinary electric rice cooker is shown.

In FIG. 7, (1) is an inner pot, (2) is an inner pot (1).
(3) is a fluorine resin (tetrafluoroethylene resin or the like) coating layer, and (4) is a scale indicating a water level.
The scale (4) is formed to protrude in an arc shape on the inner surface of the inner hook (1). (5) is rice put in inner pot (1),
(6) is water.

After the sharpened rice (5) is put into the conventional inner pot (1) having such a configuration, the water (6) is filled to the height of the scale (4) engraved according to the amount of the rice (5). Pour in. And
When the inner pot (1) is moved into a rice cooker (not shown) and the switch is turned on, the rice cooker generates heat and heats the water (6) in the inner pot (1) to cook rice (5). Is done.

[Problem to be Solved by the Invention] As described above, the inner pot (1) of the conventional rice cooker is a metal material (2) having a coating layer (3) uniformly formed on the surface.
Made of. Then, a scale (4) is displayed by forming an arc-shaped protrusion at a predetermined position on the inner side surface. That is, the scale (4) indicating the water level is displayed in the shape of a protruding portion that protrudes in an arc shape. Therefore, since the scale (4) has the same color continuously as the surrounding coating layer (3), the display of the scale (4) becomes extremely unclear. For this reason, sometimes, the inner pot (1) is moved to a bright place to judge the water level, or a troublesome operation such as illuminating the inside of the inner pot (1) with a flashlight to check the water surface is performed. If rice is cooked in an unclear manner without checking the appropriate water level, the water surface will be off the scale (4). When the water surface shifts upward and exceeds an appropriate amount, the cooked rice is “porridge”
, And when the amount is small, there is a possibility that "raw cooking" may occur.
In addition, if the scale (4) is composed of a protruding portion, the scale (4) may be hit by "scratching" at the time of laying, or may be rubbed by a scourer at the time of washing, thereby causing the coating layer (3) to peel off. There was a point.

The present invention has been made in order to solve such problems of the conventional inner pot, and displays indicators, characters, symbols, and the like clearly, and is easy to handle, and it is easy to check the water level and the like. Thus, a cooking container with high cooking accuracy is realized.

Means for Solving the Problems The present invention relates to a cooking container provided with an indicator on the inner surface of a container formed by laminating a metal material with a resin coating and shaped like a container. The cooking container is formed by forming an exposed surface of a metal material on the peripheral surface of the concave portion and filling a paint of a color different from that of the resin coating into the concave portion to constitute a display body.

[Operation] A concave portion having an exposed surface of the metal material is formed at a predetermined position on the inner surface of a container molded into a container by coating the metal material with a resin. After the paints of different colors are put in, they are heated and subjected to processing such as baking. Indicators such as scales and numerals made in this manner are easily distinguished because they are different in color from the surrounding resin coating. In addition, since the exposed surface of the metal material is formed in the concave portion, the connection is strengthened because the introduced paint is in contact with the exposed surface of the material.

In addition, inner pot (1), metal material (2), coating layer of fluorine resin (such as ethylene tetrafluoride resin) (3), rice (5)
Since the water and the water (6) are the same as those in the related art, they are denoted by the same reference numerals as in FIG.

The schematic configuration of the inner pot (1) of the present invention is shown in FIGS.
It is shown in the figure. (7) of FIG. 2 and FIG. 3 is a display corresponding to the scale (4) of FIG. (70) is a colored paint constituting the display (7); (71) is a square groove-shaped recess formed on the inner surface of the inner pot (1) and filling the paint (70); (72)
Is an exposed surface of the metal of the metal material (2). The concave portion (71) is not limited to a simple point or line for forming a scale as shown, but is formed in accordance with the contour shape of the display (7) such as a character or a symbol. A character or numeral display (7) such as "white rice" or "5" formed on the inner pot (1) is shown near the center in FIG. An indicator (7) such as a scale indicates an appropriate water level line or the like with respect to the volume of rice according to the type of cooking. The inner pot (1) is housed in the outer pot (11) so that it can be freely taken out.

The inner pot (1) of the electric rice cooker having such a configuration is manufactured by, for example, the following steps.

First, an aluminum metal material (2) having a plate shape punched in a circular shape is etched, and the surface is coated with a fluororesin liquid. Next, the metal material (2) is heated to approximately 380 ° C., and the coated resin is baked to form a resin coating (3). The metal material (2) on which the resin coating (3) is layered is squeezed out into a container shape by pressing with a stratified surface inside. Subsequently, after the flange portion is "stepped", an excess edge is cut off and molded into the shape of a flanged pot as shown in FIG. After the molding, pressure is applied from the inner surface side of the inner pot (1) to the middle with a press blade having a shape and width corresponding to the display body (7). When pressure is applied from the inside by the press blade, the resin coating (3) and the metal material (2) are compressed tomographically and fall into a square groove shape. Then, as shown in FIG. 3, the exposed surface (72) of the metal material (2) of the base metal is formed above and below the concave portion (71) having a square groove shape. A silicon-based colored paint (70) conforming to the Food Sanitation Law is applied to the cut-out recess (71), and then heated at a predetermined temperature by an appropriate heating means to pass through the exposed surface (72). And is baked in the recess (71).

In this case, as the paint (70), a colored paint (70) having a color different from that of the resin coating (3) constituting the ground color, for example, a color having a high degree of discrimination having a complementary color relationship is used. The baking temperature of the paint (70) is about 20 minutes at 280 ° C., which is about 100 ° C. lower than the baking temperature of the resin coating (3), in order to set the solidification rate and prevent deterioration of the resin coating (3).
Heat. As described above, the characters and numerals such as "white rice" and "5.6" in FIG. 1 and the linear "scales" are displayed on the display body (7) thus formed on the inner surface of the inner pot (1). It is.

Here, the rice (5) in the stocker is taken out while being measured with a measuring cup, and put into a bowl for rice washing to perform "rice sharpening". Transfer the polished rice (5) to the inner pot (1), pour water (6) up to the scale of the water level on the display (7) corresponding to the measurement of the measuring cup, set it in the rice cooker, and set the inner lid ( 26) and close the outer lid (20). Next, pull out the cord reel, connect the plug (16) to the outlet of the 100V power supply, and operate the operation unit (40) while watching the display window (41) on the upper surface of the outer lid (20). Make reservation settings for meal times.

When the reserved rice cooking start time comes, the timer of the microcomputer operates and the switch is turned on, and the rice cooking heater (12) and the lid heater (31) are energized. The radiant heat of the lid heater (31) cooperates with the heat generated from the rice cooker (12) provided at the lower part of the inner pot (1), and the rice (5) and water ( 6) is heated to increase the temperature of the water (6) inside. When the rice cooks and the water boils, the water in the inner pot (1) decreases and the temperature rises sharply, the temperature sensor (13) works to automatically turn on the rice cooker (12) and the lid heater (31). Will be stopped. As a result, the rice (5) in the inner pot (1) is cooked around the time of eating at the reserved time. When the push button (25) on the outer lid (20) is pressed, the latch (24) comes off the latch receiver (15) and the outer lid (20) moves the hinge shaft (22) by the elastic force of the hinge spring (23). The fulcrum is rotated and released. Then, the freshly cooked rice is served in a bowl with "shamoji" and the meal begins. After the meal, the inner pot (1) is taken out of the rice cooker and washed with a sponge or the like.

4 to 6 are explanatory views of another embodiment of the present invention.

In the embodiment shown in FIG. 4 (A), the cross section of the space of the concave portion (71) is formed in a convex shape by a convex press blade. Here, the concave portion (71) has a convex shape, and the exposed surface (72) of the metal of the metal material (2) is formed at a total of four places, two places at the top and bottom. Then, as in the case of the embodiment shown in FIG. 3, the paint (70) is applied in the recess (71) and then baked at the above-mentioned temperature. In the embodiment shown in FIG. 3A, the exposed surface (72) to be printed is divided into deep and shallow areas independently to form a two-stage structure. As a result, the deeper concave portion is driven in a wedge shape on the bottom surface of the shallow concave portion, so that the function of the so-called "anchor effect" is achieved and the printing is further strengthened.

In FIG. 4B, the concave portion (71) is formed by laser processing instead of the processing means for applying pressure by the press blade described above. When a laser beam is irradiated from the inside of the inner pot (1), the resin coating (3) and the metal material (2) are melted, and a concave portion (71) having an exposed surface (72) is formed on the pressing surface. (B) According to the embodiment shown in the figure, the baked surface of the paint (70) is baked on the metal material (2) in multiple ways (three).

In the embodiment shown in FIG. 5, the concave portion (7
When forming 1), as shown in FIG. 7A, for example, an embedding plate (73) of the same quality as the metal material (2) is applied to the surface of the resin coating (3). Then, when pressure is applied by a press blade (74) from above, the embedding plate (75) punched into the shape of the display (7) covers the resin coating (3) and is embedded while being pressed into the pressurized surface. . The state at this time is shown in FIG. Thereafter, the paint (70) is baked in the recessed portion (71) surrounded by the exposed surface (72) and the embedding plate (75) in the same manner as described above. Also in this embodiment, since the paint (70) is baked on the embedding plate (75) and the metal material (2), the same effect of fixing the paint (70) as in FIG. 4 can be obtained. In addition, if the pressure processing of the embedding plate (75) is performed in a low temperature state, it expands near normal temperature and the fixing of the concave portion (71) of the embedding plate (75) becomes stronger.

Further, in FIG. 6 (A), discontinuous concave portions (7
1) is formed on the inner wall of the inner pot (1), and a colored paint (70) is baked in the recess (71) to display a linear display (7). Also, FIG. 6 (B)
By applying the segment display of the segment type LED, the numeral "5" is displayed with the paint (70) baked in the discontinuous concave portion (71). The recesses (7) in (A) and (B)
For forming 1), any one of the pressurizing, melting and embedding plates (75) of each of the above embodiments is used. In the embodiment shown in FIG. 6, the baking surfaces of the baking paint (70) and the concave portion (71) are enlarged and become robust, as in the case of FIGS.
Also, there is an advantage that even if a part of the baking paint (70) is peeled off, the peeling is stopped at one dot or segment and does not spread to the outside dots.

As described above, according to the above-described embodiments, the display is displayed in a color different from that of the resin coating on the inner surface of the container, so that the display can be easily identified. In addition, since the display is made of a paint buried in the embedding plate or the base metal embedded in the recess, there is no fear that the display is peeled off, and the display can be used for a long time. Furthermore, since the exposed surface of the metal base metal exposed in the concave portion by press working or laser processing is covered with the paint put in the concave portion, rust prevention effect can be obtained.

In the above-described embodiment, the case where the present invention is applied to the inner pot (1) of the electric rice cooker has been described as an example. However, not only the gas cooker but also a frying pan or a pan / pot having a resin coating (3) layered thereon. The present invention can also be applied to Also,
In the embodiment of FIG. 4 (A), the convex concave portion (71) is illustrated, but it may be stepped, that is, a multi-stage in which the exposed surface (72) of the metal of the metal material (2) is divided. Any shape is acceptable.

[Effects of the Invention] As described above, the present invention forms a tomographically recessed portion on the inner surface of a container and forms an exposed surface of a metal material on the peripheral surface of the recessed portion. A cooking container was constructed in which the display was constituted by incorporating paint. This allows the display to be clearly identified,
This eliminates the need for carrying the container to a bright place or illuminating it with a flashlight to check the water level. In addition, since the paint contained in the concave portion is in contact with the exposed surface of the metal material, the bonding with the material is strengthened, and there is no fear that the display body will peel off.

Therefore, according to the present invention, it is possible to provide a cooking container that is convenient to handle, has a long life, and has excellent cooking performance.
