DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge type heating cooker suitable for simply keeping cooked food at a buffet party or the like.

[0002]

2. Description of the Related Art Conventionally, as a heating cooker for keeping this kind of food warm, a disposable type in which a metal can is filled with alcohol solid fuel has been frequently used. In the case of a heating cooker using the alcohol solid fuel, there is a problem that the combustion power becomes gradually weaker as the remaining amount of the alcohol solid fuel decreases and the thermal power becomes unstable.

[0003] In recent years, instead of such an alcohol solid fuel type heating cooker, a metal can filled with a liquid fuel containing glycols as a main raw material has attracted attention because of its superiority that the thermal power during combustion is stable. Have been. this is,
An ignition core is protruded and provided at the center of the upper top plate of a metal can filled with liquid fuel, and the ignition core draws up liquid fuel in the can and burns it by ignition. When the fire is extinguished after completion of the heat-retention cooking or the like, the fire-extinguishing wick is covered with a fire-extinguishing cap.

[0004]

The cooking device using the liquid fuel has many advantages over the solid fuel type cooking device, but has the following problems to be further solved. .

One is the case of the solid fuel system. However, since the container for filling the liquid fuel is a metal can,
It is not possible to visually check the remaining fuel.

[0006] In some cases, such as when a cooked dish is being kept warm, the ignition wick may be intentionally or inadvertently extinguished even though a sufficient amount of liquid fuel remains in the can. In particular, in a party venue or the like, when the fire extinguished once is reignited and used without confirming the remaining fuel amount, the fuel may run out during the heat retention of the dish. However, despite the fact that there is a sufficient amount of liquid fuel remaining in the can, there is a concern that the fire may be extinguished during the heat retention. It is often uneconomical.

[0007] One of the other problems is that a heating cooker which runs out of fuel is disposed of in a state in which a ignited combustion wick is attached to a can.
This is inconvenient in terms of resource saving, and also complicates waste sorting as waste.

[0008] Therefore, an object of the present invention is most suitable as a disposable heating cooker, and by making it possible to visually check the remaining amount of the heated fuel, it is possible to increase the economical efficiency by using up all the fuel, and to dispose after use. It is an object of the present invention to provide a cartridge-type cooking device that is effective in saving resources by minimizing a portion and having a reproducible structure.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a cartridge-type heating cooker according to the present invention will be described in detail with reference to the drawings.

FIGS. 1 (a) and 1 (b) are a front sectional view and an external perspective view showing only a fuel cup 1 as a fuel container in a cartridge type heating cooker according to the present embodiment. The fuel cup 1 is formed by molding a transparent or translucent synthetic resin material into a mold so that the remaining amount of the internally-filled, for example, glycol-based liquid fuel 2 can be checked at a glance. The fuel cup 1 can be disposable as a single product due to running out of fuel, but can be regenerated by pouring the remaining liquid fuel 2 as the remaining amount. In a state before use, the lid sheet 3 made of a laminate sheet material is hermetically sealed along the opening edge at the upper end of the cup by thermocompression bonding or the like.

In preparation for use, the prepared fuel cup 1 is fitted with the combustion wick unit 10 shown in the drawings from FIG. 3 onward, and the cartridge type heating cooker of the present invention is set.

As shown in FIG. 2, the prepared lid sheet 3 of the fuel cup 1 is cut along a predetermined opening cutting line 4 with a cutting tool such as a cutter 5 and opened, and the combustion wick unit 10 is placed there. Be attached. Alternatively, it is also possible to peel off and remove all of the cover sheet 3 and to attach and set the combustion wick unit 10 on the upper opening edge of the fuel cup 1 which is fully opened.

FIGS. 3 and 4 show the latter method, in which the lid sheet 3 is peeled off and removed, and the combustion core unit 10 (FIG. Ref.) Is set.

The configuration of the combustion wick unit 10 is a donut disk-shaped base 1 having a size to cover the entire open surface of the fuel cup 1.
One. A flange-like flange 1a is provided on the periphery of the upper end opening of the fuel cup 1 around the circumference thereof. A base 11 is joined to the flange 1a via a packing 12 made of a ring-shaped heat insulating sheet material.

A disk-shaped centering flange 13 large enough to cover the circular opening 11a at the center of the base 11 is provided.
Are connected by a stop screw 14 via a ring-shaped packing 17 made of a heat insulating sheet material.

At the center of the centering flange 13, a flat rectangular boss ring 13a bent inward is formed.
A metal holding bush 15 is fitted to the inner surface of the boss ring 13a via a ring-shaped O-ring 18 made of a heat-resistant rubber material while ensuring liquid-tight sealing. Further, a core holding member 16 bent and formed into a rectangular shape in a plane is fitted and held on the inner surface of the metal holding bush 15. Lead holding bracket 16
The holding side walls 16a of the four sides of the plane are bent from the bottom to form a flat rectangular shape, and the vertically split slits 16b formed at the corners of the four sides allow elastic holding force between the holding side walls 16a to be obtained. Has become.

A square rod-shaped combustion core member 2 having a rectangular cross section is provided inside the core holding member 16 having the four holding side walls 16a.
0 is elastically held. The combustion core 20 has its tip 21 protruding outside and above the centering flange 13. By forming an emboss 16c or the like on the core holding bracket 16 so as to protrude from the inner surface of the holding side wall 16a,
The holding power of the combustion core 20 is increased. Also, the holding side wall 1
By pulling out and forming the retaining claw 16d at the key point of 6a, the fitted core holding member 16 is prevented from coming off from the boss ring 13a.

When the combustion core material 20 is used for a long period of time, the suction of the liquid fuel 2 may be reduced due to the large amount of carbon attached to the surface. With that in mind,
Whether the core holding bracket 20 is discarded by removal together,
Alternatively, it is possible to remove only the combustion core member 20 while leaving the core holding member 20 and replace it with a new one.

In use, the combustion core 20 sucks up the liquid fuel 2 in the fuel cup 1 and ignites the tip 21 so as to keep the cooked food warm. The remaining amount of the liquid fuel 2 can be visually confirmed from the outside through the transparent fuel cup 1. When the replenishment of the liquid fuel 2 is required, the ignition combustion of the combustion core material 20 is once extinguished.

In this fire extinguishing, as shown in FIG. 5, a separately prepared fire extinguishing lid 30 covers the end portion 21 of the combustion core material 20 to cut off the supply of oxygen in the air.

After the fire is extinguished, the entire combustion wick unit 10 is removed from the fuel cup 1 and a required amount of the liquid fuel 2 is supplied. Thereafter, the combustion wick unit 10 is mounted on the fuel cup 1 and set again to prepare for re-ignition use.

During combustion use, a heat insulating packing 12 interposed between the upper end opening edge of the fuel cup 1 and the base 11 on the combustion wick unit 10 side, and the base 11 and the centering flange 13
The heat conduction is prevented by the heat insulating gasket 17 interposed between the two. This protects the fuel cup 1 from overheating and melting. Similarly, since the heat-resistant O-ring 18 is attached to the joint between the core holding member 16 and the centering flange 13 at the portion closest to the ignition combustion part in the combustion core 20, the combustion of the combustion core 20 The fuel cup 1 and the base 11 are protected from the temperature.

In the cartridge type heating cooker according to the embodiment, when the need arises after use, only the fuel cup 1 which is inexpensive in terms of cost as compared with the conventional metal can is discarded. Can be a combustion wick unit 1
0 can be reproduced repeatedly. As a result, since only the disposal of the fuel cup 1 is sufficient, the cost for sorting can be minimized.
