[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In a rice cooking utensil according to the present invention, a plurality of small projections are formed circumferentially on a side trunk surface of a rice cooking container, and a concave portion through which the small projections can pass is formed on an annular upper surface portion of a drum stove. By forming the above, the small projections are supported by the annular upper surface portion of the drum-shaped stove, and the rice cooking mode in which the distance between the solid fuel and the solid fuel is kept appropriate, and the lower top plate of the rice cooker on the upper surface of the solid fuel. It is possible to take the form of transportation and stockpiling in which the overall height is reduced by supporting.

[0006] The solid fuel in the form of a disc is formed into a multi-layered product having different calorific values and layer thicknesses, so that the combustion of the solid fuel itself can control the degree of fire, which is said to be the most important and most difficult. To automatically pull off.

Further, it is preferable that a rising portion is formed at the entire upper peripheral edge of the rice cooker, and that the upper top plate is concave toward the water inlet, so that water is poured without spilling.

[0008] When an inert gas is enclosed together with rice in the sealed rice cooker, oxidation of rice is more reliably prevented.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a sealed rice cooker in which a predetermined amount of rice (not shown) is sealed, and 9 denotes the rice cooker 1 inside. Reference numeral 15 denotes a fitted drum stove, and reference numeral 15 denotes a solid fuel provided on the bottom of the drum stove 9. If necessary, an inert gas such as nitrogen may be enclosed together with the rice.

More specifically, as shown in FIG. 2 (B), the closed rice cooker 1 has a short upper part 2 formed on the entire upper peripheral edge. Both the upper top plate 3 and the lower top plate 4 are curved concavely toward the center, and a plurality of small projections 5 are formed on the side body surface in the circumferential direction. Further, as seen in the plan view of FIG. 2A, a first tab 6 and a second tab 7 are attached to a central portion of the upper top plate 3 and a portion near the outer peripheral edge. This uses a well-known opening technique in which the score portion is cut by pulling up the attached tab in consideration of the position of the score. When the first tab 6 is raised and pulled, a small water inlet 8 is formed. Then, when the second tab 7 is raised and pulled, the entire upper top plate 3 is cut off.

As shown in FIG. 3A, the drum stove 9 has an annular upper surface portion 10 on the upper surface, and a large opening 11 into which the rice cooker 1 is inserted. A plurality of recesses 12 are formed on the inner peripheral edge of the annular upper surface portion 10 so as to be able to pass through the plurality of small projections 5 of the rice cooker 1 described above. A plurality of exhaust holes 13 and combustion air holes 17 for allowing combustion gas to escape are formed in the side trunk surface of the drum stove 9. The exhaust hole 13 is provided in the annular space 1 between both sides of the drum-shaped stove 9 and the sealed rice cooker 1 in FIG.
The annular space 14 serves as a flow path for the combustion gas of the solid fuel 15. The solid fuel 15 includes a plurality of solid fuel layers 15a, 15b, and 15c having different calorific values and layer thicknesses.
Is a donut board shape and is adhered on a fixing plate 16 made of corrugated paper. For example, the solid fuel layer 15a of the present embodiment ignites the entire solid fuel in about 10 seconds, and the solid fuel layer 15b is a solid fuel layer 15b suitable for rice cooking.
0 ° C. can be maintained, and the solid fuel layer 15 c
The temperature can be maintained at 0 to 100 ° C.

The rice cooker 1 can occupy two positions, a solid line and a dashed line in FIG. The former is a rice cooker 1
Of the small protrusion 5 of the drum stove 9 with the concave portion 12
The rice cooker 1 is vertically movable, and the lower top plate 4 of the rice cooker 1
Is a mode of transporting and stockpiling which is lowered to a position where it comes into contact with the solid fuel 15. In the latter case, the small projection 7 of the rice cooker 1 is supported by the annular upper surface portion 10 of the drum stove 9, This is a rice cooking mode in which the plate 4 is raised so as to maintain an appropriate distance from the solid fuel 15.

In order to cook rice using the rice cooker, first, the first tub 6 of the rice cooker 1 is raised and pulled to be cut off in a round shape to form a water inlet 8 (the sealed state is thereby broken). . An appropriate amount of water necessary for cooking rice is poured from the water inlet 8. In this case, the shape of the upper top plate 3 which is concave toward the rising portion 2 of the entire upper peripheral edge of the rice cooker 1 and the water inlet 8 is effective for pouring water without spilling.
Next, the solid fuel 15 is ignited. At that time, rice cooker 1
If it is desired to remove the rice cooker 1 from the drum stove 9, the rice cooker 1 may be pulled upward by aligning the small projections 5 of the rice cooker 1 with the recesses 12 of the drum cooker 9. When cooking rice,
The rice cooker 1 is set in the state shown by the one-dot chain line in FIG. The combustion air flows in from the intake hole 17, and the combustion gas generated by the combustion of the solid fuel 15 is discharged from the exhaust hole 13 through the annular space 14. After the rice has been cooked for a predetermined time, raise the second tub 7 and raise the top plate 3
Cut off the whole.

[0014]

Since the present invention is implemented in the form described above, the following effects can be obtained.

Since the rice stored in the sealed rice cooker does not come into contact with the outside air, deterioration due to oxidation can be prevented, and the demand for long-term storage can be sufficiently satisfied. In addition, a water injection port for pouring water required for rice cooking into the rice cooker using the first tab can be easily formed, and after the rice is cooked, the second water injection port can be formed.
It is a sealed rice cooker because it easily removes the entire top plate using the tabs and makes it easy to take out the rice inside.
This does not mean that the usability or the convenience of cooking rice is impaired.

Further, since the small projection on the rice cooker side can be moved up and down with the phase matched with the concave part on the drum-shaped stove side and locked with the phase shifted, wasteful space can be saved during transportation and storage. It is easy to reduce the overall height so as to eliminate it, or to keep a desired distance from the solid fuel when cooking rice.

Further, the solid fuel in the form of a disc is made of a laminate comprising a plurality of layers having different calorific values and layer thicknesses.
For example, if the fuel composition, thickness, etc. are determined so that the desired amount of heat is obtained in the first, middle and last three stages, the desired degree of heat is automatically achieved only by allowing the fuel to burn, and the user can determine what Even if you don't, by the time the solid fuel burns out, rice will be delicious.

When a rising portion is formed on the upper peripheral edge of the rice cooker and has a concave top plate shape, it is possible to obtain a form suitable for pouring the precious water into the rice cooker without spilling particularly valuable water in the event of a disaster.

When nitrogen gas is enclosed together with rice, the antioxidant effect on rice is further assured, and therefore, it greatly contributes to long-term storage.
