Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a warming tool used for keeping food warm on a table.

[0002]

[Problems to be solved by conventional techniques and devices]

 A hot water roaster is known as a device for keeping food warm on a table. However, because the heat capacity of the incubator is small, it is difficult to use it for a long period of time, and since the upper temperature limit is low, it functions only as a heat insulator. Although a tabletop stove is known as a means for cooking other than keeping heat on the tabletop, it requires gas piping or electric wiring and cannot be used in places without any equipment. Therefore, the present invention proposes a cooking heat insulator that can be used at high temperature for a long time.

[0003]

[Means for Solving the Problems]

 The cooking heat insulator according to the present invention comprises a core portion formed of a metal heat transfer body and an outer circumference portion formed of a ceramic heat storage body, and an appropriate number of through holes penetrating the front and back sides of the outer circumference portion. It is characterized by being formed. Further, in the above-mentioned heat retaining device, a heating wire is embedded in the outer peripheral portion and a socket portion for connecting to the heating wire is additionally provided. Further, instead of the ceramic body, a metal outer plate filled with heat storage particles may be used in the outer peripheral portion, and in this case, a through hole is provided in the core portion.

[0004]

[Action]

 If the outer peripheral part (heat accumulator, heat accumulating particles) with a large specific heat is preheated and the object to be heated is placed on the heat retaining device =, the heat of the outer peripheral part will pass through the core to the object to be heated. The heat is transmitted to the object to be heated and kept warm. In addition, heat is supplied to the heat storage body by energizing the heating wire buried in the outer peripheral portion.

【Example】

 Next, an embodiment of the present invention will be described. The heat retaining device of the first embodiment shown in FIGS. 1 to 4 is composed of a core portion 1 and an outer peripheral portion 2, and the core portion 1 is a columnar body made of a metal having good thermal conductivity such as pure copper, copper alloy, or aluminum. 11 and an upper plate 12 and a lower plate 13, and a sintered ring-shaped outer peripheral portion 2 is sandwiched between the upper and lower plates 12 and 13, and the upper and lower plates 12 and 13 are screwed to the pillar body 11 and the outer peripheral portion 1 and the outer periphery. The unit 2 and the unit 2 are integrated. The outer peripheral portion 2 is made of heat-resistant glass, alumina, cordierite, titanium oxide, white carbon, etc., which are solidified by an appropriate joint, sintered, and integrated. It is formed in an appropriate shape at the time of sintering, and a through hole 21 into which the pillar 11 is inserted and a recess 22 into which the upper and lower plates 12 and 13 are fitted are formed, and a radial groove 23 is formed on the back surface. In addition, a proper number of through holes 24 penetrating the front and back are provided, the heating wire 25 is embedded inside, and the socket portion 26 is attached to the outer peripheral side surface.

[0008] The heat retaining device thus accumulates heat by energizing the internal heating wire 25 or by directly heating it with a gas stove or the like, and as shown in FIG. The container C in which food is stored is placed on the upper surface of the heat retaining tool A to keep the food warm. At this time, since the core portion 1 having good heat conduction is provided in the center, the heat is efficiently transferred to the container C, and the temperature of the outer peripheral portion (heat storage body) 2 is increased to increase the heat storage amount. If it is put, not only the heat of the dish can be kept but also the cooking itself can be done.

Further, as shown in FIG. 4, the heat insulator of the present invention is placed on a gas stove E when heating a gas such as a kettle D in which heat of a gas flame escapes along with the outer circumference of the container. When the kettle D is placed on the top, the heat of the gas flame is concentrated on the bottom surface of the kettle D through the through holes 24, and the heat transfer from the core part 1 is also added, so that there is also a usage method in which the thermal efficiency is improved.

The second embodiment shown in FIGS. 5 and 6 comprises a core portion 3 and an outer peripheral portion 4 as in the first embodiment, and the core portion 3 is made of a metal having a good thermal conductivity. Therefore, the through hole 31 is provided near the outer circumference. The outer peripheral part 4 is an outer plate 41 made of a thin metal plate such as aluminum and the like, and the inner part is filled with the heat storage material similar to that of the first embodiment as particles 42, and the cylindrical leg part 43 is formed on the lower surface. The leg portions 43 are continuously provided, and a groove 44 for communicating the inside and outside of the cylindrical shape is provided in the leg portion 43.

In the second embodiment, heat is mainly stored by using a gas stove. When the gas stove is placed on the gas stove and the gas is ignited, air is supplied from the groove 44 and the flame escapes from the through hole 31. In this heating, normal cooking can be performed, and after the completion of cooking, the heat insulation device of the present invention is stored in an insulating case, and the container in which the food is stored is placed to keep the food warm. The present invention is not particularly limited to the materials shown in the above-mentioned embodiment as long as it is composed of a core portion having a high thermal conductivity and an outer peripheral portion having a large specific heat.

[0010]

[Effect of the device]

 As described above, the present invention is a heat-retaining device having a core part with good heat conduction and an outer peripheral part with a large specific heat, and can keep food warm for a long time, and can also cook on a table by raising it to a high temperature. It will be. Furthermore, by providing a large number of through holes in the outer peripheral portion and core, heat can be easily stored from the external heat source to the outer peripheral portion, and it can be used as a tool for improving the thermal efficiency during gas heating. By doing so, there is an advantage that it is possible to perform intermediate heating during heat retention.
