Title:
SANITIZATION DEVICE USING ELECTRICAL DISCHARGE
Document Type and Number:
WIPO Patent Application WO/2015/015587
Kind Code:
A1
Abstract:
A sanitization device which comprises a charged fine water droplet supply means and a plasma generation means, wherein the charged fine water droplet supply means and the plasma generation means are disposed on an air passage wall face in this order from upstream relative to the direction of air flow. The plasma generation means is composed of a charged fine water droplet supply unit and a plasma generator. The charged fine water droplet supply unit includes a high voltage power supply, an earth electrode and an electrode to which water is supplied by a water supply means, with a high voltage being applied to the electrode to which water is supplied negatively with respect to the earth electrode. The plasma generator includes a pair of plasma generation electrodes and a high frequency power supply, the plasma generation electrodes being covered with a dielectric and being disposed on a same plane as the dielectric. The air is plasmatized and discharged by a voltage being applied to the plasma generation electrodes by the high frequency power supply. Thereby, a strong sterilization effect and suppression of toxic substances can both be achieved
