【Example】

 Hereinafter, the structure of the simple cooker of the present invention will be described in further detail with reference to an embodiment having a structure in which the heating device can be attached to and detached from the lower surface of the pan body. In the figure, reference numeral 1 indicates a cylindrical or prismatic outer container utilizing the principle of a thermos bottle. The main body 2 is an upper lid that hermetically closes the upper opening of the outer container body 1, and preferably the entire opening of the outer container body 1 can be opened.

Reference numeral 3 denotes a pan body of a cooking container which is removably housed in the outer container body 1, and is usually made by deep-drawing an aluminum plate, and when the upper opening of the pan is made openable by a lid body 4. In each case, a connecting portion 5 is formed on the lower edge of the lower end so that the heat generating device described below can be attached thereto.

Further, 6 shows a heat generating device in which the ignition means is a match-type igniter, and as shown in FIG. 2, a solid fireproof is provided in the bottomed cylindrical body 6a which can be fitted into the connecting portion 5. -The heat insulating body 6b is loaded, and the self-combustion type heat generating body 6c is placed on the upper surface of the fireproof / heat insulating body 6b in a replaceable manner, while the igniter has the igniter 6d as the bottom surface of the bottomed cylindrical body 6a. The igniting agent 6e slightly exposed from above is exposed to the lower surface of the heating element 6c through a through hole 6f provided in the fireproof / heat insulating body 6b.

In the figure, 7 is a food material, 8 is an auxiliary dish that is placed on the pot body as necessary, and 9 is a cold / hot material such as an ice bag or a chemical warmer.

Although the bottom surface of the pot body 3 in the above-described embodiment is formed to have a convex shape corresponding to the protruding amount of the heating element, this portion may have a planar configuration. Further, as the refractory / heat insulating body 6b of the heat generating device 6, for example, a special ceramic made of silicon as a main material and made into a sponge by firing is used. Further, the self-combusting heat generating body 6c is made of ferrosilicon. The powder used was a mixture of ferric oxide powder and iron oxide powder of a lower order than that, which was fixed by compression molding and solidified. Furthermore, match pills are used as the ignition powder 6d of the ignition tool, and the ignition powder 6e is easily ignited and burned by the heat of the ignition powder, for example, fine powder metal and metal oxide. It uses a composition synthesized from a product. Thus, the heating device 6 of the present invention is not particularly limited to the composition and structure of each member as long as it has a heating element of an amount corresponding to the purpose of cooking and an ignition tool for igniting the heating element. Further, the ignition means in the igniter is not limited to the match type, but a lighter type or a battery type may be substituted.

[0017] Next, to describe how to use the simple cooker of the present invention having the above-mentioned configuration, first, the desired vegetables, meat, etc., which are cleaned as the food material 7, are chopped into appropriate sizes, and together with an appropriate amount of water or soup stock. It is housed in the pan body 3. In this case, when it is desired to separate vegetables from meat or juice, the pan body 3 is stored in the outer container body 1 after being wrapped in a wrap film or a small container. Then close the lid. In the structure of the above embodiment, the heating device 6 may be attached to the lower end of the pan 3 either before or after the food 7 is stored in the pan 3, or before cooking (immediately before ignition). There is no problem.

However, when the pot body 3 is stored and hermetically sealed in the outer container body 1, an ice bag made by freezing water in a season when the outside air or room temperature is high, or an iron powder type so-called chemical warmer in cold regions. The temperature of the contents is adjusted by storing the cold / hot material 9 such as the above directly on the upper lid 4 of the pan or via the auxiliary plate 8 to prevent the decay and freezing thereof.

When the simple cooker of the present invention thus prepared is cooked, the pot body 3 is taken out from the outer container 1, the cooling / heating material 9 and the wrap film are all removed, and then the heating device 6 is used. After confirming that it has been installed correctly, you can ignite the ignition charge 6d using rubbing paper, or you can use another matcher, a gas lighter, or other ignition device. The flame of the explosive propagates through the igniting agent 6e to instantly burn the heating element 6c, and the cooking is completed in 10 to 30 minutes.

Although not shown in the drawings, as another embodiment of the present invention, there is one in which the pan body 3 of the cooking container and the heat generating device 6 are integrally structured. By extending the bottom surface of the pot body 3 in a middle-height shape to one side surface of the pot body and closing this portion with a door or the like, the heating element 6c of the heating device 6 can be installed from outside the pot body at any time. It is designed to be replaceable, and the ignition tool can be loaded through the bottom hole of the heat generating device 6 into the through hole 6f penetrating the heat insulating body 6b so that the cooking container can be repeatedly used. It is possible to use.
