る。2. Description of the Related Art In a conventional heat storage device 1 of this type, a container 2 is filled with a latent heat storage material 3 and a melting process is performed by a heating heater 4 in contact with the container 2 and heat exchange between the convection air 5 and the container 2 is performed. In the regenerative electric hot-air blower 14 as shown in FIG. 6, a heat storage device is provided for selectively supplying heat to the container 2 and releasing heat by repetition of the solidification process. 1 is provided in a ventilation path 9 for convection air of an electric hot-air heater 14 and energizes the heater 4 at night or the like when heat radiation is not required to store heat energy. The heating is maintained until the combined operation of the blower 14 is performed, and by using it together with the electric blower 14 in the morning when necessary, a heating capacity higher than that of the electric warmer 14 is obtained.

積減少に伴って容器２の上方には、空間１２が生じる。As described in Japanese Patent Application Laid-Open No. 2-203198, this type of conventional heat storage device using a latent heat storage material and utilizing a phase change is generally of this type. When the heat storage material 3 used in the application becomes a solid phase, its volume is reduced, and as shown in FIG. 7A, the heat storage material is solidified below the container 2 by the action of gravity. Creates a space 12.

きな欠点を有していた。When the solidified state is heated by the heater 4, the heater 4 begins to melt from a high temperature distribution on the surface of the heater 4, and if the temperature distribution is not uniform, it partially melts as shown in FIG. At the beginning (dot portion), volume expansion starts from the portion where melting has begun, and a very large stress is applied between a portion still solidified (shaded portion) and a container portion surrounding the portion where melting has begun, resulting in deformation of the container 2. In addition, the liquid heat storage material leaks out of the container due to the breakage of the joint portion and the like, and has a major drawback that it cannot be used as a heat storage device thereafter.
