Embodiment Construction
[0145] Embodiments of this invention will now be explained with refence to drawings and tables. FIG. 1 is a view for showing an embodiment of a thawing and freshness keeping device according to this invention.
[0146] A refrigerator has a heat-insulating material 2, an outer wall 5, and a temperature adjusting mechanism (not shown) therein. A metal shelf 7 has a two-shelf structure, and objects such as vegetables, meat and fishes and shellfishes to be thawed, freshness-kept and matured are put on each shelf. The metal shelf 7 is insulated from the floor of the refrigerator by an insulating body 9.
[0147] Further, a high voltage generating device 3 can generate direct and alternating voltages of 0-500 V, and the interior of the heat-insulated material 2 is covered with an insulating plate 2a such as vinyl chloride and the like.
[0148] A high voltage cable 4 for output a voltage of the high voltage generating device 3 is connected to the metal shelf 7 through the outer wall 5 and the heat...
