Abstract: Provided is an ozone generator for generating ozone using high voltage discharging between an electrode plate forming a first electrode and a heat sink forming a second electrode. The ozone generator includes: an inner tube and a middle tube each of which is concentrically disposed, the electrode plate being interposed between the inner tube and the middle tube; an adhesive sealing both ends of the electrode plate; an electrode pipe for electrically connecting to a power source and disposed within the electrode plate; a passage formed through a middle of the heat sink; and an outer tube installed in an inner periphery surface of the passage, the outer tube being concentrically disposed to maintain a predetermined distance from an outer periphery surface of the middle tube.

Abstract: An ozone water producing system and control method, which is flexibly used indoor or outdoor irrespective condition of a flow channel, is provided for reconstituting polluted water as environmentally friendly. The ozone water generating system is maintained in an optimum state for improving entire performance of the system as well as predicting and preventing the backflow of ozone water, which is occurred due to outlet blocking in a discharging process. The controlling method of the present ozone water producing enables to prevent the deteriorating the performance and ensure the operation stability. The ozone water-producing system comprises an influent air controller, an injector, a gas-liquid separator, and an ozone water-backflow, preventing device. The present system and controller is designed to prevent water backflow, being frequently occurred in the conventional system, for improving the performance, stability and extending operating lifetime.
