接合された連絡部分である。Configuration of Conventional Example and Its Problems As shown in FIG. was installed. The heat storage container 1 has a bag-shaped container 4 formed by heat-sealing, gluing, or the like a laminate film 3 made of a flexible material, such as synthetic resin and aluminum foil, and Inside the bag-shaped container 4 is sodium acetate trihydrate (melting point 58
℃) and a supercooling prevention agent 6.
was included. 7 is a connecting portion to which the laminate film 3 is joined.
上記構成において、蓄熱はヒータ線２が放出す

を通して蓄熱材５が受熱することにより行われ

して蓄熱を完了する。 In the above configuration, heat storage is carried out by transferring the heat emitted by the heater wire 2 to the surface 4a of the bag-like container 4 that is in contact with the heater wire 2.
This is done by the heat storage material 5 receiving heat through the heat storage material 5. Then, all of the heat storage material 5 melts (solid → liquid)
to complete heat storage.

能とする蓄熱材５の量は本質的に多く袋状容器４
の厚みは大きくなり、そこで短時間に蓄熱を完了
するためにはヒータ線２から蓄熱材５への入熱を
効率よく行う必要がある。 The biggest advantage of using the heat storage material 5 as a body warming device, such as a hot vest, is that it becomes cordless after heat storage is completed, and considering its practicality as a warming device, it can complete heat storage in a short time and maintain heat radiation for a long time. It has to be possible. The heat radiation time is mainly determined by the insulation performance, the heat radiation rate, and the amount of the heat storage material 5, but the amount of the heat storage material 5 that allows the heat radiation time of several hours while maintaining the body's sense of warmth as a body warming device is Essentially many bag-like containers 4
becomes thicker, so in order to complete heat storage in a short time, it is necessary to efficiently input heat from the heater wire 2 to the heat storage material 5.

蓄熱することができなかつた。 However, in Fig. 2, the heater wire temperature T 1 during heat storage,
Temperature T 2 of the front surface 4a of the bag-shaped container 4, temperature T 3 of the back surface 4b
As shown in the temperature-time curve, heat input from the heater wire 2 to the heat storage material 5 is performed in one direction from the surface 4a of the bag-like container 4 in contact with the heater wire 2. When the back surface 4b temperature T 3 reaches approximately 60°C, the temperature curve T 3 in FIG . , over 80℃.
This means that the amount of heat input from the heater wire 2 is much larger than the amount of heat received by the heat storage material 5. These temperatures are determined by the normally used laminate film 3 and the supercooling preventive agent 6 in the bag-like container 4.
Considering the heat resistance temperature (100℃ and 80℃, respectively), this is a factor that significantly reduces the safety and durability of the heating device. That is, the communication portion 7 of the heat storage container 1 may peel off and the heat storage material 5 may leak to the outside, or the crystallization of the heat storage material 5 may be adversely affected during heat dissipation (supercooled state). For this reason, the heating capacity (W) of the heater wire 2 could not be increased too much, and heat could not be stored in a short period of time.

いて記述したが面ヒータでもよい。 According to the above configuration, the bag-shaped container 10 in which the heat storage material 11 and the supercooling preventive agent 12 are sealed is placed on both sides.
0a, 10b can be heated by the heater wire 14, and the length of the heater wire 14 in contact with the bag-shaped container 10 can be increased. FIG. 4 shows the temperature T 4 of the heater wire 14 during heat storage in the embodiment shown in FIG.
The temperature-time curves at T 5 and T 6 are shown for the temperatures of both outer surfaces 10a and 10b of the bag-like container 10, respectively. Temperature T 5 at both outer surfaces 10a, 10b of the bag-like container 10,
T 6 is almost the same (in reality, it differs slightly depending on the external insulation configuration.
Not shown in the figure. ) At the time of completion of heat storage (i.e., both outer surfaces 10a, 10b of the bag-like container 10
This is the inflection point of the temperature curves T 5 and T 6 and points to point Y in FIG. ), the heater wire 14 temperature T 4 is approximately 80℃
Therefore, both the temperatures T 5 and T 6 of the bag-like container 10 and the heater wire temperature T 4 can be kept low.
Moreover, heat storage can be completed in a short time. As mentioned above, since the length of the heater wire 14 can be made long, it is possible to reduce the heating density (W/m, the amount of heat generated per 1 m of the heater wire 14) while maintaining the heating capacity (W) of the heater wire 14 as a whole. can. Further, the heat storage material 11 is
In order to heat the heat storage material 11, the thickness of the heat storage material 11 can be made thin for a given length of the heater wire 14. Therefore, rapid heat storage is possible, and the temperature difference between the temperature of the heat storage material 11 and the bag-shaped container 10 temperatures T 5 and T 6 and the temperature of both sides 10a and 10b of the bag-shaped container 10
T 5 and T 6 can be kept low. This is because the difference between the amount of heat generated by the heater wires 14 on both sides 10a and 10b of the bag-like container 10 (excluding heat radiation loss) and the amount of heat received by the heat storage material 11 can be eliminated. Also,
Since the temperature of the heat storage material 11 inside the bag-like container 10 can be lowered, the life of the supercooling inhibitor 12 can be significantly extended. Although the above embodiment is described using the heater wire 14, a surface heater may also be used.
