Abstract:
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.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0108]    A water treatment equipment implemented by the invention has a circular or box shape, in which water introduced by water supply pipe (hereafter referred to as raw water) is firstly clarified and then purified. At the bottom of water reservoir body with purified water outlet and inlet filling and draining purified water, a cylinder of water clarifier and a cylinder of water purifier are provided. The cylinder of water clarifier has an inlet at the intake side of water clarifier, while within the cylinder of water clarifier the cylinder of water purifier has a purified water outlet and a membrane-clarified water outlet. A clarified water processing cartridge is mounted in the cylinder of water clarifier and a water outlet at the exit side of water clarifier is disposed on the top of the cylinder. A water clarifier cap with space for a water purifier cap covers the cylinder of water clarifier with padding interposed so as to form a water clarifier. A reverse osmosis (RO) membrane processing cartridge is mounted in the cylinder of water purifier. A water purifier cap with a clarified water intake receiving clarified water covers the cylinder of water purifier with padding interposed so as to form a water purifier. At the portion of the body excluding said water purifier and said water clarifier, a body cover is fixed and sealed by a fixed pin or other means with padding interposed to form a water reservoir. Raw water is taken from water intake at water purifier inlet side utilizing water pipes such as hose (hereafter referred to as water pipe), then is dispensed from water outlet at exit of water clarifier after clarification, and then is conveyed into the clarified water intake of the water purifier for receiving clarified water through a water pipe for purification in the water purifier. Purified water is dispensed from purified water outlet, and then conveyed into purified water outlet and inlet of water reservoir through a water pipe. The water is stored in the pressure water reservoir with pressure of raw water, and air in the upper section of pressure water reservoir sustains the pressure. When the purified water outlet spigot is opened, purified water is dispensed automatically with the sustained pressure. Membrane-cleaning water, which cleans the surface of RO membrane when producing purified water, is discharged from membrane-cleaning water outlet through a water pipe. Said water clarifier, said water purifier and said pressure water reservoir are formed integrally.

         [0118]    When purified water is produced with RO membrane, purified water is stored in water reservoir  12  and a floater  56  with built-in magnet floats with the level of water reservoir  12 . When the level inside water reservoir  12  raises to a certain height, liquid level switch a 57  instructs computer  54  to turn off solenoid valve  55  for stopping water supplying as a response through magnet  58  of the floater. Vice versa, liquid level switch A 57  instructs computer  54  to turn on solenoid valve  55  for resuming purified water supplying as a response of lowering magnet  58  of the floater with the liquid level. 
         [0119]    Reference number  36  of  FIG. 10  refers to an upper air section of water clarifier to alleviate impulsion on water clarifier.
