PURPOSE:To suppress the rise of the temperature under the heat-resistant temperature to prevent supercooling and to prevent the generation of supercooling by a method wherein an aluminium layer at the side of a vessel is provided on a heater, and furthermore, an aluminium layer at the side or a heat insulation material is provided on the surface of the heat insulation material. CONSTITUTION:The aluminium layer 13 at the side of the vessel is provided on the heater 5, and furthermore, the aluminium layer 14 at the side of the heat insulation material is provided on the surface of the heat insulation material 9. When the heating and heat accumulating are carried out to a latent heat accumulating material 1 using the heater 5, if the surface of the heat insulating material such as a cusion, because heat is diffused to the parts which are not covered with the heat keeping material by the working of the aluminium layer at the side of the heat insulation material, the latent heat accumulating material will not be heated to the temperature surpassing the heat-resistant of a supercooling preventing material 2. |
