20090173686 | WATER TREATMENT DEVICE - Prior water treatment equipments have several water clarifying process filters, water purifier and water reservoir separated from each other, occupying too much space to install under a water tank and resulting inconvenient installment. The water treatment equipments for home cannot be received in water tanks, and thus water clarifier and water purifier are disposed in the water tanks while the water reservoir is disposed separately. Water pipes are connected in between. Therefore, water clarifying processors, water reservoir and water purifier utilizing RO membrane may be integrated to eliminate unnecessary space in existing systems. | 07-09-2009 |
20130056405 | SPOUT FAUCET - Disclosed is spout faucet that: eliminates clogging of a water purifier and a demineralizer; backwashes and cleans particles treated by a filter, which are the cause of clogging, to remove same from the filter, and cleans and discharges same to outside a unit; regenerates the filter and eliminates the inconvenience for users of being forced to replace the filter due to clogging because backwashing is not performed, even though the filter still maintains sufficient filtering capacity; and can discharge and spout from a sink discharge water from a water treatment unit and use same as general service water, to address the issue of hygiene, because currently a hose is inserted into an drainage pipes underneath sinks, and the problem of increasingly serious fresh water shortages in the future. | 03-07-2013 |
