<p>PROBLEM TO BE SOLVED: To provide a simple heater capable of easily and efficiently heating wet tissues to an appropriate temperature in a short time. SOLUTION: This simple heater is an equipment capable of heating the wet tissues 9 by using a heat sensitive electric resistance type planar heating element 4. As one example of the simple heater, the one provided with a tray main body 5 and a tray lid 6 can be mentioned. The heating element 4 is laid on the bottom surface 7 of the main body 5. In the state of closing the main body 5 by the lid 6, a clearance capable of housing the several sheets of the wet tissues 9 is provided between the inner surface 8 of the lid 6 and the surface of the heating element 4. When the heating element 4 is energized from an energizing part 10, heat is generated. When the temperature rises to a fixed temperature, electric resistance becomes large and the temperature of the heating element 4 does not rise to be higher than the fixed temperature. Thus, the wet tissues 9 are easily and efficiently heated to the appropriate temperature in a short time.</p> |
