SPACE POTENTIAL GENERATION DEVICE, A STORAGE DEVICE FOR MAINTAINING A FRESHNESS OF AN OBJECT STORED THEREIN USING SUCH SPACE POTENTIAL GENERATION DEVICE, AND FRYER PROVIDED WITH SUCH SPACE POTENTIAL GENERATION DEVICE

摘要

A space potential generator according to the present invention includes atransformerformed by magnetically connecting a primary coil and a secondary coil, afeedback controlcircuit feeding back one terminal of the secondary coil to one terminal of theprimary coilto adjust voltage of the secondary coil, an output control portion provided onthe otherterminal of the secondary coil to impart low frequency vibration to an outputof thesecondary coil, a static electricity discharger formed of conductive materialand providedon the other terminal of the secondary coil via the output control portion,the space potentialgenerator does not have a grounding electrode, a weak current flowing throughthesecondary coil is 0.002 to 0.2 A, the static electricity discharger is coveredwith aninsulating member to discharge predetermined static electricity to surroundingspace, andelectric field of target voltage is formed in the surrounding space by thedischarged staticelectricity.
