Abstract:
An ozone water-producing system including an ozone generator having an ozone generating unit for receiving air and changing oxygen contained in the received air into ozone to generate the ozone, a mixer adapted to mix the ozone supplied from the ozone generator with water supplied from a water source, a solenoid valve installed in a water supply line to control a flow of water supplied to the mixer from the water source and a gas-liquid separator adapted to separate gas and liquid, the ozone water producing system comprises:an influent air control means adapted to purify and dehumidify intake air passing through an air solenoid valve installed the flow path of ambient air introduced into an ozone generator; an injector connected to a water supply line and an ozone gas supply line so as to form an ozone gas from air purified and dried through the influent air control means and mix the ozone gas with water, the injector adapted to open a check valve installed at a position where the ozone gas supply line and the water supply line meet by means of water injection through a flow rate of water to allow the ozone gas to be dissolved into water; a gas-liquid separator having a certain space enabling a separation of gas and liquid and adapted to perform a repeated ozone dissolving process in such a manner that it receives first ozone water obtained by mixing and dissolving the ozone gas into the water via the injector, allowing ozone to subsequently be dissolved into water to produce second ozone water in the gas-liquid separator and discharges ozone water in a liquid state consisting of ozone dissolved in water through a drainpipe while allowing ozone in a gaseous state which is not dissolved in water to re-enter the gas-liquid separator through a return line to allow ozone to thirdly be dissolved into water to produce ozone water in the gas-liquid separator; and an ozone water-backflow preventing means installed along the interior space of the gas-liquid separator and adapted to detect a limit water level of the ozone water accumulated in the gas-liquid separator and control a flow of water through the water supply line according to the flow state of the ozone water to prevent a backflow of the ozone water.
