本発明は融解熱を利用する蓄熱材を用いて身体

療法等に用いられる蓄熱ユニツトに関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat storage unit that uses a heat storage material that utilizes heat of fusion to heat local areas of the body, and is used for thermotherapy to alleviate body pain.

いる。Structure of conventional example and its problems As shown in FIG. 1, this type of conventional heat storage unit is composed of a heat storage container 5 and a heater 6 that comes into contact with the heat storage container 5 and heats the heat storage material 4. Ta. The heat storage container 5 includes a heat-sealed portion 2 formed by stacking flexible films 1 such as Al laminate films and heat-sealing a portion thereof, and a bag-shaped container portion 3 surrounded by the heat-sealed portion. and a bag-like container part 3
The inside is filled with a heat storage material 4 such as paraffin.

状態はつねに変化し、上述したような蓄・放熱プ
ロセスを安定してかつ効率よく繰り返すことがで
きなかつた。 In the above configuration, first, heat is stored in the heat storage material 4 by heat released when the heater 6 is energized. The heat storage material 4 gradually changes phase from crystal (solid) to melt (liquid) and stores heat as heat of fusion. Further, most of the heat radiation is completed when the power supply to the heater 6 is stopped, and the phase of the melt of the heat storage material 4 gradually changes to crystals and releases heat of fusion. Here, the heat storage material 4 in a molten state is a low viscosity liquid and has high fluidity. In addition, since the material of the heat storage container 5 itself is the flexible film 1, the surface of the heat storage container 5 filled with the heat storage material 4 is easily deformed by a slight external pressure and becomes an uneven surface. There is no means to restore this uneven surface to a flat surface. Therefore, the contact state between the heat storage container 5 and the heater 6 constantly changes, making it impossible to repeat the heat storage/radiation process as described above stably and efficiently.

性があつた。 Further, the output W of the heater 6 is designed to be large in order to store heat in the heat storage material 4 in a short time.
If the heat released by the heat storage material 4 is not efficiently stored in the heat storage material 4, that is, if the contact between the heat storage container 5 and the heater 6 is poor and the efficiency is low, the temperature of the heater 6 will rise and become high, resulting in disconnection of the heater 6 and fire. There were risks such as

時にヒートシールされている。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. A flexible film 7 such as a heat-sealable Al laminate film (ex. polyester/Al foil/nylon/polyethylene) is stacked on top of the other and a part of the film is heat-sealed to form a gap 8.
A heater 11 such as a tubing heater or a planar heating element is provided on a heat storage container 10 filled with a heat storage material 9 such as CH 3 COONa/3H 2 O.
It is housed in a heat-sealable flexible bag-like container 12 such as a laminate film with at least one side open, and the opening 13 is sealed under reduced pressure. Note that the lead wire 14 of the heater 11 is heat-sealed at the same time as the opening 13 of the flexible bag-shaped container 12 is sealed.

圧下で封じても良い。 In the above configuration, the flexible bag-like container 12 contracts, and the heat storage container 10 and the heater 11 are reliably fixed, and the flexible bag-like container 12 is contracted, so that they come into close contact with each other. Since the interior of the flexible bag-like container 12 is maintained at a reduced pressure, while the heat storage material 9 repeats the heat storage and heat dissipation process, the heat storage container 10 and the heater 11 always return to their original positions even if an external force is applied. A stable close contact state with a wide contact area can be achieved. Therefore, the heat of the heater 11 during heat storage is efficiently transferred to the heat storage material 9. Moreover, since the heat storage container 10 is housed in the flexible bag-like container 12, even if the heat storage container 10 is damaged by a pinprick or the like and the heat storage material 9 leaks, leakage to the outside can be reduced. In addition, although the case of one heat storage container was shown in the said Example, a plurality of heat storage containers may be used. Furthermore, the heat storage container 10 may be stored in the flexible bag-like container 12 in which the heater 11 is installed in advance in the flexible bag-like container 12 and the lead wire 14 is heat-sealed and pulled out, and the heat storage container 10 is sealed under reduced pressure. good.
