Description

[Detailed Description of the Invention] [Industrial Application Field] Generally, the inner surface of the inner pot of an electric rice cooker is coated with a resin coating of non-compatible Teflon (trade name: tetrafluoroethylene resin). ing. The resin coating layered on the inner surface prevents cooking ingredients from sticking to the inner pot and corroding it, which occurs when cooking rice.

On the other hand, a scale is provided on the inner surface of the inner pot to indicate the appropriate water level for the amount of rice to be cooked. The number attached to the water level scale indicates the number of cups of rice measured using the measuring cup. Then, the rice is cooked after transferring the polished rice to the inner pot and adding water to the 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 in particular, the inner surface is coated with resin and is provided with indicators such as scales and numbers indicating the water level, letters and symbols indicating the type of cooking, etc. This invention relates to improvements in cooking containers.

[Prior Art] FIG. 5 is an explanatory diagram of the configuration of a conventional device, in which an inner pot for an ordinary electric rice cooker is shown.

In FIG. 5, (1) is the inner pot, (2) is the metal material of the inner pot (1), (3) is the coating layer, and (4) is a scale indicating the water level. The scale (4) is formed to protrude in an arc shape on the inner surface of the inner pot (1). (5) is rice placed in the inner pot (1), and (6) is water.

A conventional inner pot (1) with this structure is filled with polished rice (5).
After that, pour water (6) up to the height of the scale (4) engraved according to the amount of rice (5). Then, the inner pot (
1) into a rice cooker (not shown) and turn on the switch, the rice cooker generates heat and the water (1) in the inner pot (1) is heated.
6) is heated and rice (5) is cooked.

[Problems to be Solved by the Invention] As described above, the inner pot (1) of the conventional rice cooker is made of a metal material (2) with a coating layer (3) uniformly layered on its surface. Then, a scale (4) is displayed by forming an arcuate protrusion at a predetermined position on the inner surface. That is, the scale (4) representing the water level is displayed in the shape of an arcuate protrusion. Therefore, since the scale (4) is continuously the same color as the surrounding coating layer (3), the display of the scale (4) becomes extremely unclear. For this reason, it is sometimes necessary to move the inner pot (1) to a bright place to judge the water level, or to perform troublesome operations such as illuminating the inside of the inner pot (1) with a flashlight to check the water surface. If you neglect to check the appropriate water level and cook rice without knowing it, the water level will deviate from the scale (4). If the water level rises and exceeds the appropriate amount, the cooked rice will become close to ``rice porridge 2'', and if it is low, there is a risk that it will become ``raw cooked''. In addition, if the scale (4) is composed of a protruding part, "
There were problems such as being hit by a rice scoop or being rubbed with a "scouring brush" during cleaning, causing the coating layer (3) in this area to peel off.

The present invention was made in order to solve the problems of the conventional inner pot, and it is convenient to handle by clearly displaying indicators, characters, symbols, etc., and it is easy to check the water level etc. This is to realize a cooking container with high cooking accuracy.

[Means for Solving the Problems] The present invention provides a cooking container in which a display body is provided on the inner surface of the container formed into a vessel shape by layering a resin coating on a metal material. A cooking container is constructed by forming matching recesses and filling the recesses with an embedded plate of a color different from that of the resin coating.

[Function] A rectangular groove-like recess that matches the shape of the display is formed from the inside at a predetermined position of a container made of a metal material coated with resin and molded into the shape of a lid, for example by press processing. . At the same time, the backing plate is punched out using a press, and an embedded plate with a color different from that of the resin coating is embedded in the formed recess.

Display bodies such as scales and numbers made in this way are easily identified because they are different in color from the surrounding resin coating.

The same reference numerals as in the figure are given.

A schematic structure of the inner pot (1) of the present invention is shown in FIG.

(7) in FIG. 2 is a display corresponding to the scale (4) in FIG. (70) is an embedded board constituting the display body (7);
(71) is an embedded plate (70) formed on the inner surface of the inner pot (1).
It is a rectangular groove-shaped recess filled with. The recesses (71) are not limited to simple points or lines forming a scale as shown in the figure, but are formed in accordance with the contour shape of the display body (7) such as characters or symbols. “White rice” and “5” formed in the inner pot (1)
A display (7) with letters and numbers such as "" is shown near the center of Figure 1.The display (7), such as a scale, shows the appropriate water level line for the volume of rice depending on the type of cooking. etc. This inner pot (1) is connected to the outer pot (11) so that it can be taken out freely.
) is housed within.

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

First, an aluminum metal material (2) made of a circularly punched plate is etched, and a fluororesin liquid is applied to the surface. Next, the metal material (2) is heated to bake the painted resin layer, and a resin coating (3) is formed. The metal material (2) on which the resin coating (3) is layered is drawn into a lid shape using a press with the layered surface facing inside. The flange is then "stamped" and the excess edges are cut off to form the flange pot as shown in FIG. After molding, as shown in FIG. 3(A), for example, a backing plate (72) for an embedding plate is applied to the surface of the resin coating (3). Then, pressure is applied halfway from the inner surface of the inner pot (1) with a press blade (73) having a shape and width corresponding to the display body (7). When pressure is applied from the inside with the press blade (73), the resin coating (3) and the metal material (2) are compressed in a tomographic manner and collapse. At the same time, the embedded plate (70) punched out in the shape of the display body (7) is coated with resin (
3) and is embedded in a press-fit state.

The state at this time is shown in figure (B). Embedded board (
If the pressure processing (70) is carried out at a low temperature, the fat will expand at around room temperature, and the fixing of the embedded plate (70) in the recess (71) will become even stronger. Further, the embedded plate (70) is suitably made of a corrosion-resistant material with a color different from the resin coating (3) constituting the ground color, for example, a highly distinguishable metallic color such as stainless steel. As mentioned above, the characters, numbers, linear scales, etc. such as "white rice" and "5゜6'" in Figure 1 were formed in this way on the inner surface of the inner pot (1) and displayed in color. This is a display body (7).

Here, take out the rice (5) inside the stocker while measuring it with a measuring cup, put it in a bowl for washing rice, and do "rice polishing." Transfer the polished rice (5) to the inner pot (1) and measure it. Water (6) reaches the water level scale on the display (7) corresponding to cup measurement.
), then set it in the rice cooker, cover it with the inner lid (26), and close the outer lid (2o). Next, pull out the cord reel, connect the plug (16) to a 100V power outlet, and operate the operation unit (40) while looking at the display on the display window (52) on the top of the outer cover (2o). Set a meal time reservation.

When the scheduled start time for rice cooking arrives, the microcomputer's timer activates and turns on the rice cooking heater (12) and lid heater (
31) is energized. The radiant heat of the lid heater (31) is transmitted to the inner pot (
The rice (5) and water (
6), the temperature of the internal water (6) rises. When rice cooking progresses and the water boils and the water in the inner pot (1) decreases and the temperature rises rapidly, the sensor (13) is activated and the rice cooking heater (12) and lid heater (31) are automatically energized. will be stopped. As a result, the rice (5) in the inner pot (1) is cooked until it is ready to eat at the reserved time.

When the push button (25) on the outer lid (20) is pressed, the latch (2
4) comes off the latch holder (15) and the hinge spring (23)
Due to the elastic force, the outer cover (20) is rotated about the hinge shaft (22) and opened. And the freshly cooked rice is “
The meal begins when the rice is placed in a rice bowl using a rice scoop.After the meal, the inner pot (1) is removed from the rice cooker and washed using a sponge.

FIGS. 4(A) and 4(B) are explanatory diagrams of another embodiment of the present invention.

In the embodiment shown in FIG. 4, discontinuous recesses (71
) is formed on the inner wall of the inner pot (1), and an embedded plate (70) is embedded inside this recess (71) to form a linear display body (7).
is displayed. Also, (B) is 7
By applying the segment display of the segment LED, the number "5°" is displayed on the embedded board (70) embedded in the discontinuous recess (71).In the case of (A) and (B) To form the recess (71), the punching process using the pressure of the press described above is used.In the embodiment shown in FIG.
2) The sides will be continuous. As a result, after the embedding plate (70) is punched out by applying pressure with a press, the embedding plate (72) can be continuously peeled off, resulting in good workability.

Furthermore, even if a part of the embedded board (70) comes off, there is an advantage that the separation will stay at one dot or segment and will not spread to other dots or the like.

In addition, in the above-mentioned embodiment, the present invention is applied to the inner pot (1) of an electric rice cooker.
), but the present invention can be applied not only to gas rice cookers but also to frying pans, pots, and pots coated with resin coating (3).

[Effects of the Invention] As described above, the present invention provides a display body in which a concave portion matching the shape of the display body is formed on the inner surface of a container, and a resin coating and an embedded plate of a different color are embedded in this concave portion. A cooking container was constructed. Therefore, the display body is displayed not only by its shape such as unevenness as in conventional cooking containers but also by coloring, so that the display body can be clearly identified. Therefore, there is no need for troublesome operations such as carrying the container to a bright place or checking the water level by shining a flashlight on it. Furthermore, since the display body is constructed of an embedded board that is embedded in the recess and has a color different from the ground color, there is no fear that the display body will peel off. Furthermore, if the metal material is covered with an unbalanced embedding plate as in the embodiment, corrosion can be prevented.

Therefore, according to the present invention, it is possible to provide a cooking container that is easy to use, has excellent cooking performance, and can withstand long-term use.
