DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic sectional view showing an embodiment of a tabletop type hot water pot according to the present invention.

In FIG. 1, reference numeral 10 denotes a portable container, and reference numeral 11 denotes hot water (also referred to as hot water) filled in the container 10. 12
A heat storage material is preferably a latent heat storage material that absorbs and releases heat energy due to a phase change of a substance, and is provided to be freely mounted and removed. At present, heat storage materials are attracting attention from the viewpoint of industrial waste heat recovery and effective use of low-cost energy sources (solar heat, midnight power, etc.). Particularly, latent heat storage materials are sensible heat storage materials such as water and concrete. Compared to,
Because the amount of energy that can be stored per unit volume and weight is overwhelmingly large, it is being used for various applications including cooling and heating systems.

[0014] A new type of heat storage material has been developed, which has the characteristic of maintaining an apparent solid shape even when heat is stored. This is produced by using paraffins, which are organic latent heat storage materials, as a main component and compounding them with an organic polymer. Since the solid shape is maintained even during heat storage, a sturdy container is not required, and it can be processed into various shapes.

Although the heat storage material retains its shape even in the heat storage state,
Paraffins, which are heat storage components, undergo a phase change inside the heat storage material. That is, the heat storage material is heated above its heat storage temperature to absorb heat of fusion (heat storage), and is exposed to an atmosphere below the heat storage temperature to release heat of solidification (radiation), whereby the heat storage material itself softens and hardens. repeat.

Since this state change is not due to a chemical change, it operates stably for a long period of time, and because it is an organic material using paraffin as a heat storage component, such as supercooling and phase separation found in inorganic heat storage materials. No phenomenon occurs. In addition, there is a case where one kind of heat storage material is used to store heat at a predetermined temperature depending on a heating temperature, and a case where a rated temperature is different according to a use temperature, and a rated temperature according to a use temperature is used. The above is an example of the heat storage material 12 used in the present invention, and it goes without saying that other heat storage materials can be used.

An example of the characteristics of the heat storage material 12 is as follows.
Seal with a thickness of 5t, seal strength is 2500g or more /
Inch, dimensions are 170mm long × 120mm wide × 25thickness
mm, weight is 500 g.

The heat storage material 12 must be heated to a predetermined temperature during use to store heat. For this reason, heat storage methods include heating in a microwave oven for a certain period of time and storing heat at a predetermined temperature, immersing it in a constant temperature water bath for a certain period of time and storing heat at a constant temperature up to the temperature of the hot water, or storing it in a constant temperature room for a long time In addition, there is a method of storing heat at a temperature in a constant temperature room.

In this case, when using the heat storage material 12 for which the rated temperature is determined, a material having a rated temperature suitable for the operating temperature is used. Otherwise, for example, the heating time of the microwave oven is adjusted so as to reach a predetermined temperature.

FIG. 2 shows a heat storage method using a hot water system. An electric heater 21 is provided at the bottom of the container 20, and the container 20 is filled with hot water (hot water) 22. The heat storage material 12 is immersed in hot water 22. The hot water 22 is always kept at the set temperature by a control circuit (not shown), and the heat storage material 12 in the hot water 22 also stores heat at that temperature. In this method, a large number of heat storage materials 12 can always be kept at a predetermined temperature.
It is more suitable for business use than a method using a microwave oven that may overheat or is not suitable for mass production. Table 1 shows data in the case of microwave heating, and Table 2 shows data in the case of heat storage by a hot water bath.

Next, the sake warming method of the present invention will be described with reference to FIG.

A heat storage material 12 and a hot water 11 heated to a certain temperature by a microwave oven without using a direct heat source are put into a container 10, and a table 13 is provided together with a sake bottle 13 containing cold sake. In FIG. 1, the liquid storage 13 may be placed on the heat storage material 12 or may be placed sideways depending on the shape of the heat storage material 12 or the like. Table 3 shows data examples.

Table 3 shows the temperature ranges for warm, good, and hot sake.
Cold sake refers to 7 ° C to 15 ° C.

The temperature of the heat storage material 12 is set in advance based on the heating time of the microwave oven and the heat capacity of the heat storage material.
By simply changing the temperature of the hot water 2 or hot water 11, it is possible to cope with changes in seasons such as summer and winter and changes in customer preferences, and since the heat source is not a power source but an indirect one, it can easily cope with an increase in the number of units. .

FIGS. 3 to 7 show the temperature of the heat storage material 12 and the hot water 11.
The change of the temperature of the sake in the sake bottle 13 with the elapse of time with respect to the temperature is shown in a graph. The amount of hot water 11 was 1.5 l, the volume of sake bottle 13 was 1 go (150 cc), and the temperature was 26 ° C.
As is evident from the results of this experiment, the predetermined temperature (50 ° C.) was maintained within the required temperature range (45
(50 ° C. to 50 ° C.).

FIG. 3 shows a graph in the case of using only the hot water 11 without using the heat storage material 12 by a dotted line. Hot water 1 as you can see
Although the temperature of 1 was 60 ° C, the temperature of sake in Tokuri 13 was 4
It only rises to 6 ° C. and it takes 13-14 minutes. 4 to 7, the case of only the hot water 11 is omitted.

FIG. 8 shows various shapes of the heat storage material 12. The main purpose of the heat storage material 12 is to give the stored heat energy to the hot water 11 to keep the temperature of the hot water 11 within a required temperature range for a long time. It is possible to improve heat conductivity from the heat storage material 12 to the liquid storage 13. That is, FIG. 8 (a) shows a graphic guide portion 12a formed in the center, and FIG. 8 (b) shows a plurality (four in this case) of peripheral portions.
Is formed.

In the above-described embodiment, the temperature of the hot water 11 is set higher than the temperature of the heat storage material 12, but conversely, even if the temperature of the heat storage material 12 is the same as or lower than that of the hot water, May be set so that the change over time of the temperature is within a predetermined temperature range. In this way, heat energy is rapidly supplied from the warm water in the early stage of the low temperature of the sake bottle 13 and heat energy is thereafter supplied from the heat storage material.

The heat storage material 12 may be coated with a thermo-color material, and the color change may be used to obtain an indication of the heat storage temperature.

[0030]

According to the present invention, the tabletop doko and the sake brewing method according to the present invention contain warm water in a portable container, and heat the bottle with the warm water to warm the liquid in the bottle. Since the heat storage material is heated to a predetermined temperature in a short time, and is provided in the hot water, and the temperature of the hot water is kept within a required temperature range for a long time as compared with the case of only the hot water, a heat storage material that can be freely taken out is provided. The optimal time for warming can be kept much longer than when warming with only hot water. Therefore, not only sake but also other liquids can be heated properly. In addition, since no electric cord, gas pipe, and the like are required as in the related art, it is suitable for a tabletop type, and it is possible to enjoy liquor and the like safely and slowly.

Since the heat storage material is provided with a liquid guide portion, the liquid does not fall down when warming.

Further, since the heating temperature of the heat storage material is set to a temperature higher than the temperature of the hot water which determines the hot water temperature, heat energy is supplied from the heat storage material to the hot water from the beginning, so that the proper hot water is provided. be able to.

Further, since the heating temperature of the heat storage material is set to a temperature equal to or lower than the temperature of the hot water for determining the hot water temperature, the temperature in Tokuli falls rapidly from the warm water at the beginning of the low temperature. Since the heat energy is supplied and then the heat energy is supplied from the heat storage material, it is possible to perform a warm-up warming.
