れていた。2. Description of the Related Art Conventionally, as shown in FIG. 5, this type of heat storage device includes a heat storage pack 2 in which a heat storage material 1 is placed on one or both sides of a string-like heater 3. A method has been adopted in which the heat storage material 1 is controlled to change its phase from a solid to a liquid to store heat, and when used, the solidification heat is kept warm by a surrounding heat insulating material 5 and the heat is gradually radiated and used for heating.
発明が解決しようとする問題点
一般に蓄熱材を用いる装置に望まれる条件は、蓄熱時間
が短く、安全であることである。ここで、蓄熱時間は、
加熱ヒータの電気容量に大きく影響する。短間間で蓄熱

ｍを大きくすると、ヒータ３の温度が高くなり蓄熱材
１の耐熱温度を越えてしまうので電気容量を大きくでき
なかった。Problems to be Solved by the Invention Generally, the conditions desired for a device using a heat storage material are short heat storage time and safety. Here, the heat storage time is
It greatly affects the electric capacity of the heater. If you want to store heat in a short period of time, you can increase the electric capacity of the heater, but if the string-shaped heater 3 is used as described above, W/
If m was increased, the temperature of the heater 3 would rise and exceed the heat resistance temperature of the heat storage material 1, making it impossible to increase the electric capacity.
従って蓄熱に時間がかかる外、蓄熱材１の温度を耐熱温
度以上に上げない為に、安全装置としてサーモスタット
８等が、必要であった。Therefore, not only does it take time to store heat, but also a thermostat 8 or the like is required as a safety device to prevent the temperature of the heat storage material 1 from rising above the heat-resistant temperature.

のである。Means for Solving the Problems In order to solve the above problems, the present invention provides a plurality of heat storage packs containing a latent heat storage material, a planar heating element made of a positive temperature characteristic resistance element for heating the packs, and a planar heating element that heats the packs. It consists of a heat insulating bag that has a heat insulator for wrapping and keeping it warm, and a hanging metal fitting.
作 用
このような構成にすれば、発熱体の抵抗変化が、常温か

が不要となる。Effect With such a configuration, the resistance change of the heating element is small from room temperature to the melting point of the latent heat storage material, and becomes large above the melting point. Therefore, the electric capacity until heat storage increases, the time until heat storage becomes shorter, and after the heat storage is completed, the electric capacity becomes smaller and stable, so a temperature control device such as a thermostat becomes unnecessary.
実施例
以下、本発明の一実施例を添付図面にもとすいて詳細に
説明する。EXAMPLE Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

パック２との熱交換を良くした面状発熱体を形成する。In FIGS. 1 and 2, reference numeral 15 denotes a band-shaped heating element made of a positive temperature characteristic resistance element for heating the heat storage pack 2. The heat storage pack 2 Forms a planar heating element that improves heat exchange with the heating element.

温袋６で覆っている。Also, the latent heat storage material 1 is arranged so as to correspond to the two heating elements 15.
When two rows of heat storage packs are installed in which a plurality of thermal storage packs are placed in close contact with each other from above and below, a flexible bending part 14 is installed in the center to fit the body, and the entire circumference is insulated. It is wrapped in a material 5 to keep it warm, and the whole thing is covered with a heat insulating bag 6 having a hanging fitting 7.

The change in heater temperature and resistance value is as shown in Figure 3. Immediately after the start of communication, a large current flows as shown by the broken line A, and until the latent heat storage material melts, the electric capacity becomes approximately 100 W or more, and the electric capacity increases for a short time. (about 40 to 50 minutes), heat storage is completed, and the temperature of the heat storage material becomes stable at around 70 to 80°C, forming a curve like the solid line A. On the other hand, in the conventional case using a conventional string heater, heat storage is completed and the thermostat is activated approximately 80 minutes after the start of energization, as indicated by the broken line. The temperature of the heat storage material in this case is indicated by the solid line.

。As the latent heat storage material 1 in this example, hydrated salt-based sodium acetate trihydrate (CH3C○○N a ・3H20) was selected, and lithium fluoride (LiF) was selected as the supercooling prevention material.
A system stabilizer (S58-229317) was used. The melting point of IJium acetate trihydrate is 58°C, but the approximate temperature at which all the heat storage bags melt is 65°C.
According to the configuration of the present invention, the heat storage time can be shortened by about 30 degrees. Also, this latent heat storage material 1
The heat-resistant temperature is around 90°C, and it is necessary to maintain the temperature within the difference between the melting point and the heat-resistant temperature, that is, between 20 deg and 30 deg. The temperature behavior of the latent heat storage material 1 is such that once it has finished melting, its specific gravity is smaller than that of water (because it is 0.7).
As a result, the temperature rises rapidly. In the conventional string heater type, simply increasing the electric capacity would result in the thermostat not being able to keep up with the temperature of the heat storage material, and during that time the heater temperature would rise and exceed the heat resistance temperature of the heat storage material, resulting in overcooling. A phenomenon occurs. Therefore, the saturation temperature of the positive temperature characteristic resistance element is set from 70°C to 85°C.

By having a heat insulating bag with metal fittings and configuring the heating element with a positive temperature characteristic resistance element, it is possible to provide a safe heat storage device that can store heat in a short time and prevents the heat storage material from being overcooled.
