Released from the heat radiation side to the outside,
Thereby, the inside of the refrigerator is cooled. In other words, since cooling is performed only by supplying electric current, in the case of the conventional compressor type, it is almost inevitable that the size of the device accompanying the switching of the refrigerant to the alternative fluorocarbon is almost inevitable, but such a large size is caused. No Although there is no movable part in principle,
Even if it exists, it is only a fan arranged on the cooling side and the heat radiation side of the Peltier element, so that maintenance is easier than that of the compressor type. Therefore,
In addition to avoiding an increase in size in response to the era of CFC-free, maintenance-free operation can be achieved.

According to a second aspect of the present invention, in the first aspect of the present invention, the cool box main body includes an opening for allowing the mortuary to enter and exit the cool box main body, and an opening / closing door provided to close the opening.
