Patent ID: 7850769

Claim:
An air filtering apparatus for filtering air with electrolytic water comprising: a housing having an air suction port and air blow-out port; an electrolytic bath for generating electrolytic water; a gas-liquid contact member disposed in the housing; an electrolytic water supply unit for supplying the electrolytic water to the gas-liquid contact member so that the electrolytic water infiltrates into the gas-liquid contact member; an air blowing fan for bringing indoor air sucked from the air suction port into contact with the electrolytic water infiltrating in the gas-liquid contact member and blowing out the indoor air from the air blow-out port; a water receiving portion for receiving the electrolytic water passed through the gas-liquid contact member; and a foreign material removing mechanism that removes foreign materials contained in the electrolytic water and disposed in an electrolytic water supply/circulation passage through which the electrolytic water flows from the electrolytic bath through the electrolytic water supply unit to the gas-liquid contact member and further passes from the gas-liquid contact member through the water receiving portion, wherein the foreign material removing mechanism has a filter member that is freely detachably mounted in the electrolytic water supply unit and filters the electrolytic water introduced from the electrolytic bath to remove the foreign materials, wherein the electrolytic water supply unit has an electrolytic water supply tray having an electrolytic supply hole formed in the bottom portion thereof, the electrolytic water passing through the filter member being supplied to the gas-liquid contact member through the electrolytic water supply hole; and further comprising a water level sensor for detecting a water level of the electrolytic water in the electrolytic water supply tray, and an alarm unit for alarming a user so that the filter member should be exchanged when it is detected by the water level sensor that the water level in the electrolytic water supply tray reaches a predetermined water level.
