Description

[Detailed description of the invention] a. Purpose of the Invention (Field of Industrial Application) The present invention is applicable to homes, restaurants, bento shops. Related to a rice cooker with a heat storage body used in school lunch facilities, etc.

(Prior art) Conventionally, a rice cooking pot, a long-leg switchable heater that heats the pot with flame, and a heater that absorbs and accumulates the heat of the flame are installed between the pot and the heater. heat storage elements that radiate to the pot, and flame paths that are present in these heat storage elements and allow the long flame of the heater to pass through and reach the bottom of the pot to heat the bottom of the pot. A stationary rice cooker is known from Japanese Patent Publication No. 61-7089, which was invented by the present inventor.

(Question M that the invention seeks to solve) In the conventional rice cooking device described above, in the early stage of rice cooking, the large leg of the heater is made long so that the flame reaches the bottom of the pot through the flame path of the heat storage element, and the high temperature flame is heated. As the pot is heated, the temperature inside the pot rises rapidly and boils within 15 minutes, so the first condition of rice cooking according to the rice cooking theory is completely satisfied. Once the fire is extinguished, the heat storage element, which is red-hot by the long flame, continues to heat the pot without causing a temperature drop even when the heating is switched from the flame to radiant heat. The second rice cooking condition of continuing heating while absorbing water is met, and the third cooking condition is that the rice is heated for a certain period of time without lowering the temperature in the pot by even 1°C, and finally excess water is completely eliminated. It also satisfies the needs of rice cookers, so it has the feature that it can be easily done without the hassle of cooking perfectly delicious rice, just like with the ancient pot.

However, with this rice cooking device, if the heat storage capacity of the heat storage element is set to be sufficient for the volume of the pot, the heat that is absorbed and accumulated by the heat storage element while heating the boiling pot with a long flame will be absorbed and stored. The subsequent process of heating the pot at a constant temperature for a fixed period of time can be carried out without heating the heat storage element with flame. If it can be done by lowering the rice cooker, the next pot is placed on the heater during this time, and the flame is used to heat the pot, eliminating the idle time of the heater, increasing its operating efficiency, and increasing the rice cooking capacity. However, since the heat storage element described above is installed on the heater side, if the pot is removed from the heater, it will no longer be heated by heat radiation from the heat storage element. Since the rice cooker must be placed on top of the heater, the heater is idle for a considerable amount of time, resulting in poor operating efficiency and, above all, low rice cooking ability.

The present invention has been made to solve the above-mentioned conventional problems, and when a flame or electromagnetic waves are passed through the passage to heat the pot, the heat is absorbed and stored, and the heat is then radiated to the pot. By attaching it to the bottom of the pot, if you want to heat the pot at a constant temperature for a certain period of time after boiling, you can lower the pot from the heater, place a pond pot in place of it, and heat it with flame or electromagnetic waves. In order to make this possible, we are aiming to install two rice cookers with N heating elements, which will eliminate the idle time of the heater and improve its operational efficiency, greatly increasing the rice cooking capacity. Summary, Structure of the Invention (Means for Solving the Problems) The means of the present invention for achieving the above object includes a rice cooking pot and a rice cooking pot that is housed in the lower part of the pot and absorbs and accumulates heat from flames or electromagnetic waves. A rice cooker with a heat storage body is provided with a heat storage body that radiates heat to the pot, and a passage that is present in the heat storage body and allows flame or electromagnetic waves to pass through to heat the bottom of the pot by the flame or electromagnetic waves. .

(Function) The rice cooker with a heat storage body configured as described above can be used by placing a pot containing rice and water on top of the heater, and either igniting the heater, energizing it to generate a flame, or using electromagnetic waves. When a flame or electromagnetic wave is generated, the flame or electromagnetic wave rises through the passage in the heat storage body without heating the heat storage body, hits the bottom of the pot in a way that wraps it, heats the bottom of the pot to a high temperature, and rapidly lowers the temperature inside the pot. While raising the rice to a boil, the heat storage body absorbs and stores sufficient heat necessary for subsequent heating at a constant temperature for a constant time.

When the rice boils as described above, the rice grains absorb water and lose their fluidity, so the pot is removed from the heater and placed on a warming stand, and the next pot is placed in the empty heater. If you put it on the table and heat it with flame or electromagnetic waves as above, the pot on the heat retention table will be heated by the abundant heat radiated from the heat storage body during this time, so when changing from flame or electromagnetic wave heating to radiant heating. Heating is continued while water is absorbed smoothly into the rice grains without causing a temperature drop. During this time, the temperature inside the pot remained in this state for a certain period of time without dropping even 1°C.
It works to completely eliminate excess water in cooked rice, and the starch is fully alpha-converted, resulting in extremely delicious rice.

(Example) An example of implementation of a rice cooker with a heat storage body according to the present invention will be described below based on the drawings.

In Figure 1 of the drawings, 1 is a pot suitable for cooking rice using a flame heater, the capacity of which is set according to the capacity of the rice to be cooked, and a heater (not shown) with long legs is placed under the bottom of the pot. A heat storage body 3 with legs 2 which absorbs and accumulates heat from the flame and radiates it to the pot 1 is housed, and the upper opening is covered with a lid 5 having the necessary weight and having a knob 4. The above-mentioned heat storage tree 3
In the drawing, the heat storage body 3 is attached to the pot 1 by passing a screw 7 through the hole 6 in the center and tightening it to the pot 1, but the mounting position and means are limited to those described above. Rather, any means that can fix the heat storage body 3 to the bottom of the pot 1 can be widely used, and examples thereof will be omitted.

In addition, when the heat storage 3 mentioned above radiates the heat absorbed and accumulated from the flame to the pot 1 until the rice boils, the pot 1 lowers its internal temperature by as much as 1°C. The volume is set so that the temperature is maintained for the required amount of time. Reference numeral 8 denotes a passage which is present in the heat storage body 3 described above and passes through the long flame of the heater, and may be several fan-shaped holes drilled at equal intervals in the circular heat storage body 3 as shown in FIG. The circular heat storage body 3 may have multiple annular holes divided into several holes as shown in FIG. 3, or the circular heat storage body 3 may have multiple radial holes as shown in FIG. 4. A large number of round holes drilled at regular intervals in a rectangular heat storage wood 3 such as the one shown in FIG. When heating with a heater, a long flame is made to reach the bottom of the pot 1 through each of the passages 8 described above, and the pot 1 is heated by the flame.

In Figures 7 and 8 of the drawings, 1 is a rice cooking pot suitable for an electromagnetic heater, and is made of iron material that generates heat by electromagnetic induction to have a capacity suitable for cooking rice for one meal. Either by wrapping it around the pot 1 as shown in FIG.
A heat storage body 3 that absorbs and stores heat emitted by electromagnetic waves from the heater and radiates it to the pot 1 without shielding the electromagnetic waves directed toward the bottom of the pot 1 is attached to the pot 1 with screws 7, etc. Open [1
Since the point where the lid 5 can be opened is the same as that of the flame heating type described above, the drawing of this part is omitted.

Next, an example of rice cooking using the rice cooker with a heat storage body shown in the above embodiment will be explained. Rice cooking example 1 Made of aluminum with a diameter of 114 mm and a depth of 80 aoa.
140 g of rice and 200 g of water at a temperature of 15℃ in a rice cooker for one meal
cc and left it for about 1 hour.

Then, put this rice cooker over a well-known gas burner and turn the gas burner into high heat. Then, a long flame is generated, passes through the passage inside the heat storage body, rises while heating the heat storage body, and wraps around the bottom of the pot, heating the pot at a high temperature. Boiling started inside the rice grains, and in about 12 minutes all the water was sucked into the rice grains. The heat storage element, on the other hand, absorbed and stored the heat from the flames and retained the amount of heat necessary for subsequent heating at a certain temperature for a certain period of time.

After heating the rice cooker for a few more minutes, remove the rice cooker from the gas burner and place it on one of the heating tables, then place the next rice cooker on top of the empty heater. The pot is heated by radiating the abundant heat absorbed and accumulated from the flame, so even if the heating is switched from the flame to radiant heat, the pot maintains an accurate temperature that does not drop even 1 degree Celsius. Cooking and shading the rice were completed at the same time by keeping it warm for several minutes. When I tried the cooked rice, I found that it was very well-alpha-condensed and delicious.

Rice Cooking Example 2 140 g of rice and 200 cc of water at a water temperature of 15° C. were placed in an iron single-serve rice cooker with a diameter of 114 nwa and a depth of 80 liters and left for about 1 hour.

This rice cooker was placed on top of a 200 V, 1200 W electromagnetic heater, and electricity was applied to the heater. Then, the heater generates strong electromagnetic waves, some of which pass through the passage in the heat storage body and wrap around the bottom of the pot, generating heat due to electromagnetic induction and heating the pot at a high temperature for 10 minutes. Afterwards, boiling started in the pot, and all the water was sucked into the rice grains in about 15 minutes. On the other hand, heat storage wood absorbs and stores the heat emitted by electromagnetic waves, and retains the heat 1 necessary for subsequent heating at a constant temperature for a certain period of time.

After heating the rice cooker for a few more minutes, remove the rice cooker from the electromagnetic heater and place it on the heating stand. When you place the next rice cooker on top of the empty heater, the rice cooker on the heating stand will absorb heat. The pot is heated by radiating the accumulated heat, so even if the heating is switched from electromagnetic waves to radiant heat, the pot maintains an accurate temperature that does not drop by even 1 degree Celsius, keeping it warm for 10 minutes. This allowed me to finish cooking and cooking the rice at the same time. When I tried the cooked rice, I found it to be a little less flavorful than the flame-heated rice mentioned above, but it was far more delicious than rice cooked in a regular rice cooker. Ta.

C. Effects of the Invention The rice cooker with a heat storage body according to the present invention generates flames or electromagnetic waves from the heater at the beginning of rice cooking, causes these to reach the bottom of the pot through the passage of the heat storage body, and uses the flames or electromagnetic waves that generate high temperature to reach the bottom of the pot. Since the pot is heated, the temperature inside the pot rises rapidly, and the first condition of the rice cooking theory that the rice will not completely gelatinize unless it boils within 15 minutes is completely satisfied. When the container is unloaded, the heat storage body absorbs and stores the abundant heat from the flame or electromagnetic waves and radiates it to the pot, thereby continuing to heat the pot without causing the temperature drop that occurs when heating is switched from flame or electromagnetic waves to radiant heat. , the second condition of the rice cooking theory is also satisfied because the rice continues to be heated while smoothly absorbing water inside the rice grain, and furthermore, during this time, the temperature in the rice cooker continues to be heated for a certain period of time without lowering the temperature by even 1 degree Celsius. Since the third condition of the rice cooking theory, in which excess water is completely eliminated, is satisfied, it is possible to easily cook delicious rice without burning the rice and with complete gelatinization, without the hassle of drawing a fire, just as with the traditional rice cooker.

Since the heat storage body is stored in the bottom of the pot, when this heat storage body absorbs and stores the heat of the flame or electromagnetic waves and has enough heat for subsequent heating at a constant temperature for a certain period of time, the pot can be removed from the heater. Lower it onto a heat-insulating table, etc., and while heating it with radiant heat,
If you place the next pot on top of the heater and heat it with flame or electromagnetic waves, the heater will continuously heat the pot with flame, eliminating the idle time of the heater. The efficiency of movement is improved, and the rice cooking capacity can be increased to +11.

If you are using a small rice cooker, such as one used for kamameshi, you can remove the pot from the heater a little early, and place the rice in the straw bowl at the audience seats, which has been done since ancient times to make the rice taste better. It has the advantage that it can be completely cooked without spoiling the rice, and the commercial value of kamameshi can be significantly improved.

It has the following unique effects.
