JP2001059093A - Solid fuel for temperature-retention and heating - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain solid fuel for retaining temperature and for heating that can sustain the combustion for more than about 60 minutes from the ignition until it burns up completely while it can retain the temperature of the cooked dish or heats the cooked dish; obtain a treatment jigs that can employ the commercially available solid fuel that has the ignition part all over the upper area of the fuel for keeping the temperature at a constant level or heating up; obtain an ignition-recognizing jig that can be used until the solid fuel burns up, and obtain a heat-conductive plate for avoiding the local heating. SOLUTION: The ignition area 12 in the combustion part comprising the main body of the solid fuel or the internal resin film is made smaller to keep the cooked dishes at a constant temperature or heat the already cool-down dishes. In the case of the commercially available solid fuel that has already the ignition area all over the upper face, a jig 18 is used to partially mask the fuel and narrow the ignition area. In addition, an incombustible material, for example, a metallic wire is supported over the solid fuel placed on the cooking stove, and a thermally conductive plate 16 is used on the cooking stove.

2. Description of the Related Art Solid fuel obtained by cutting a solid fuel rod-shaped molded product containing alcohol as a main component, exposing only the upper surface, and wrapping it with aluminum foil is disclosed in, for example, Japanese Utility Model Publication No. 58-2.
No. 9164 is known.

[0003] Further, there is also known a solid fuel in which a similar liquid fuel is poured into a metal can, solidified by cooling, and then provided with a lid which can be partially opened like a window. In this case, a metal can is used. Therefore, the cost is high, and after use, it is disposed of as a bulky empty can, but this processing is troublesome.

[0004] The above-mentioned inexpensively obtained solid fuel with an aluminum foil exterior is generally sealed and packaged with a resin film to prevent evaporation, and further provided with a heat adhesive layer on the inner surface, which is bonded to the resin film. It is wrapped and wrapped in aluminum foil with an open top surface from the bottom so that the resin film is completely burned together with the solid fuel from the top in use. An apparatus which facilitates refuse treatment by receiving it in a container and discarding it as it is is known, for example, from Japanese Utility Model Application Laid-Open No. 52949/1985.

[0005] For example, it is preferable for a customer to complete the cooking in a short time in a drive-in, lunch at a golf course, and the like in a kettle meal, and also for the business owner to increase the number of customers, so that a so-called fast customer turnover rate is obtained. In response to this, the applicant of the present application has proposed a solid fuel for early cooking that is provided with a large exposed area of the combustion part and is provided as an exterior.
No. 246616.

[0006]

However, there is a need for a faster customer turnover in terms of time. It is efficient to prepare a large number of dishes such as group customers in the kitchen before cooking and bring them to the dining table used by many people so that customers can eat immediately when they are seated. It is a target.

[0007] In this case, the cooking place prepares and prepares meals in accordance with the reservation time when the group customers arrive, but the reservation time is not protected by traffic conditions and the like, and meals are delayed after this time. In many cases, the dishes cool down during that time.

In view of such circumstances, a first object of the present invention is to provide a solid fuel for warming and warming which is mainly used for keeping warm or warming a cooked dish. A second object of the present invention is to provide a mask cover device in which a conventional solid fuel can be used for heat retention and heating. A third object of the present invention is to provide an ignition discriminating jig as a preventive measure so that a solid fuel is not burned out yet and is not burned by touching it or discarded as it is to cause a fire. A fourth object of the present invention is to provide a heat transfer plate for increasing the heat retention and heating effect, and for avoiding local heating of the cooking utensil.

[0009]

Means for Solving the Problems The first object mentioned above is as follows.
Equipped with a solid fuel body containing alcohol as a main component, a resin film for preventing evaporation, which is wrapped with the solid fuel body, and an exterior material of a flame-retardant material such as a metal foil provided with an ignition portion only on a part of the outer surface of the resin film. Is achieved by doing so. The same object is achieved by providing a solid fuel main body containing alcohol as a main component and a cladding material made of a flame-retardant material such as a metal foil having an ignition portion only on a part of its outer surface.

[0010] The second object is achieved by providing a non-combustible material molded body having a flame throttle opening on the upper surface and having a solid fuel storage portion inside. The third purpose is
This is achieved by placing a non-combustible material such as a wire in which the solid fuel is placed in the stove and supported above the ignition portion. The fourth object is achieved by providing a plate made of a heat conductive material as an intervening one between a stove using solid fuel and a bottom of a pan placed on the stove. You.

[0011]

The solid fuel is completely burned by reducing the igniting area of the solid fuel main body or the burning portion made of the resin film in the interior to reduce the thermal power, to make the burning time last for about 1 hour or more, and to completely burn the solid fuel. Thereby, the cooked food can be kept warm, and the cooled food can be heated.

[0012] For a commercially available solid fuel in which the entire upper surface portion is already ignited, a jig is used to partially mask that portion to reduce the ignited area.

In order to cause an appropriate color reaction,
A non-combustible material such as a wire is supported above the solid fuel placed in the stove, thereby identifying whether ignition has been performed, that is, whether the fuel has burned out. In addition, in order to increase the heat retention and warming effect, and to avoid local heating of vessels such as pots with cooking utensils on the stove, aluminum, copper, A heat transfer plate made of a heat conductive material such as iron, stainless steel, graphite, and ceramic is interposed.
