Since it is high and uses the characteristics of the heat generating sheet 4, there is no risk of malfunction or failure unlike a thermostat.
[0020]
Since the surface heat is generated, the heat transfer efficiency to the heat transfer plate is good, and since it is layered (adhered), there is no room for a wire or other foreign matter to enter.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, a heating plate is configured by layering a heat generating sheet capable of automatic temperature control on the back surface of a heat transfer plate having good heat transfer properties such as an aluminum plate. The heating shelf was configured by installing the heating plate in a heat insulating frame. If the said heating shelf board is installed in parallel with a shelf frame and this shelf frame is accommodated in a heat retention chamber, the heat retention display of this invention can be performed. In the present invention, since a heat generating sheet capable of automatic temperature control (specified upper limit temperature) is used as a heat source, a thermostat, a sensor and other automatic temperature control devices are not required, and the overall harm is significantly reduced. And the reliability of temperature can be improved.
[0022]
For example, different types of articles designated as 60 ° C. heating, 65 ° C. heating, or 70 ° C. heating can be displayed in the same incubator, and kept at a constant temperature near the designated temperature.
