Conventional configurations and their problems Conventionally, electric heaters embedded in heat insulating materials have been commonly used as local heaters for the human body, etc., but with these conventional electric heaters, the power cord is always required. However, the spatial usage range of the heater was limited to the length of its power cord.
In recent years, there has been a demand for a heater that continues to have a heating function for a certain period of time even after the power to the electric heater is turned off, and this requires the development of a regenerative electric heater. In addition, such a heat storage type electric heater is required to be lightweight, flexible, short in heat storage time (high heat storage efficiency), high in safety, and low in cost. On the other hand, the conventional latent heat storage method has a configuration in which a latent heat storage material is housed in a robust heat storage tank, and a heating source such as an electric heater is embedded in the latent heat storage material. There were problems in weight, flexibility, cost, etc. when adopting this conventional latent heat storage method as a heat storage method in the above-mentioned heater.

The heating elements are electrically connected to each other using lead wires, and the heating elements are covered and surrounded by at least two sealed containers containing the latent heat storage material. Furthermore, the heating element is a linear, ribbon-shaped, or planar heating element coated with electrical insulation as required, and is configured in close contact with a sealed container housing the latent heat storage material. A regenerative electric heater having such a configuration is flexible and lightweight, has a high heat storage material heating efficiency, and is low in cost. Here, as the material for the lightweight flexible sheet, in addition to electrically insulating sheets such as cloth, plastic film, and plastic laminate film, metal foil, metal foil/plastic laminate film, and the like can be used. If an electrically insulating sheet is used (if the sealed container containing the latent heat storage material is also made of electrically insulating material such as plastic), it is not necessary to cover the heating element and lead wires with electrical insulation, but The electrical insulation coating increases safety.
On the other hand, plastic, metal foil, metal foil/plastic laminate film, etc. can be used as the material for the sealed container that houses the latent heat storage material. They are lightweight, chemical resistant, water resistant, safe,
It has excellent features in terms of cost.

Example 2 A latent heat storage electric heater as shown in FIG. 2 was prototyped. 21 is a heating element, and here the same heater wire as used in Example (1) was used. Lead wires 22 were connected to both ends of the linear heating element. Four identical heating elements were made, and as shown in FIG. 2, two of them were placed on the top surface of the flexible sheet 27, and the remaining two
The books were fixed parallel to each other on the opposite lower surfaces, and alternately on the upper and lower surfaces. The flexible sheet 27 used here was a cloth having a length of 33 cm and a width of 20 cm, and the heating element 21 was fixed to the cloth using a heat-resistant adhesive and sewing. 24 and 25 are sealed containers for storing latent heat storage materials, and here, a plastic laminate film consisting of three layers of polyethylene (60 μm)/Al foil (9 μm)/nylon (12 μm) is used as the container material, with the polyethylene side facing inside. A tube-shaped container was made by thermocompression sealing. As No. 24, tube-shaped containers each having a length of 32 cm and an internal volume of 50 cm 2 were prepared. 88g of latent heat storage material 26 is placed in container 24, and 62g of latent heat storage material 26 is placed in container 25.
After filling with g, it was sealed. The latent heat storage material 26 used here is the same as that used in Example (1). 2
