FRESHNESS-KEEPING DEVICE USING SPACE POTENTIAL GENERATOR

摘要

A space potential generator includes a transformer formed by magnetically connecting a primary coil and a secondary coil, a feedback control circuit feeding back one terminal of the secondary coil to one terminal of the primary coil to adjust voltage of the secondary coil, an output control portion provided on the other terminal of the secondary coil to impart low frequency vibration to an output of the secondary coil, a static electricity discharger formed of conductive material and provided on the other terminal of the secondary coil via the output control portion, the space potential generator does not have a grounding electrode, a weak current flowing through the secondary coil is 0.002 to 0.2 A, the static electricity discharger is covered with an insulating member to discharge predetermined static electricity to surrounding space, and electric field of target voltage is formed in the surrounding space by the discharged static electricity.

主权项

1. A freshness-keeping device, comprising:
a space potential generator; and a compartment for determining a freshness-keeping space formed around the static electricity discharger of the space potential generator, wherein the space potential generator comprising:
a transformer that is formed by magnetically connecting a primary coil and a secondary coil;a feedback control circuit that feeds back one terminal of the secondary coil to one terminal of the primary coil to adjust a voltage of the secondary coil;an output control portion that is provided on the other terminal of the secondary coil to impart a low frequency vibration to an output of the secondary coil; anda plate-like static electricity discharger that is formed of a conductive material and provided on the other terminal of the secondary coil via the output control portion, the space potential generator does not have a grounding electrode, a current flowing through the secondary coil is a weak current having a range of 0.002 to 0.2 A, a static electricity is discharged from a plate surface of the plate-like static electricity discharger provided on the other terminal of the secondary coil to a space, and an electric field is formed in the freshness-keeping space by discharging the static electricity from the plate surface of the static electricity discharger of the space potential generator to keep a freshness of a food in the freshness-keeping space.
