Abstract

Abstract A bed of silver activated charcoal in combination with a downstream bed of a mixture of anion exchange resins and cation exchange resins aerate, purify, soften and dealkalize water flowing therethrough. Periodic flushing through a unit having a solution of sodium chloride or potassium chloride regenerates both exchange resins. An upright cylindrical container having screen separated compartments for the chemicals and filters receives tap water from a pressure reducing nozzle and discharges the conditioned water through a spigot. The unit containing the chemical regenerant is selectively connectable intermediate the nozzle and the container.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 256 words
A regenerative portable water conditioner for counter top use, said water conditioner comprising in combination: (a) a container having an inlet pipe for receiving water to be conditioned, a pressure reducing nozzle connectable to a conventional faucet and flexible tubing interconnecting said nozzle with said inlet pipe and a discharge pipe for discharging conditioned water; and a spigot for directly discharging the conditioned water into a vessel for immediate use; (b) an inlet compartment for receiving water from said inlet pipe, said inlet compartment being defined by a top cap; (c) a first compartment downstream of said inlet compartment, said first compartment including a quantity of activated charcoal; (d) filter means disposed intermediate said top cap and said first compartment for filtering the water flowing into said first compartment; (e) a second compartment downstream of said first compartment; (f) a cylinder for defining the walls of said first and second compartments, said cylinder having one end sealingly connected to said top cap; (g) a quantity of regenerative anion exchange resins and a quantity of regenerative cation exchange resins disposed within said second compartment for softening and dealkalizing the water flowing through said second compartment; (h) first screen means for segregating said first and second compartments; (i) an outlet compartment for receiving the water from said second compartment and directing the water to said discharge pipe said outlet compartment being defined by a bottom cap sealingly connected to another end of said cylinder; and (j) second screen means for segregating said second compartment from said outlet compartment.
Claim 2
Dependent Claim 256 words
A regenerative portable water conditioner for counter top use, said water conditioner comprising in combination: (a) a container having an inlet pipe for receiving water to be conditioned, a pressure reducing nozzle connectable to a conventional faucet and flexible tubing interconnecting said nozzle with said inlet pipe and a discharge pipe for discharging conditioned water; and a spigot for directly discharging the conditioned water into a vessel for immediate use; (b) an inlet compartment for receiving water from said inlet pipe, said inlet compartment being defined by a top cap; (c) a first compartment downstream of said inlet compartment, said first compartment including a quantity of activated charcoal; (d) filter means disposed intermediate said top cap and said first compartment for filtering the water flowing into said first compartment; (e) a second compartment downstream of said first compartment; (f) a cylinder for defining the walls of said first and second compartments, said cylinder having one end sealingly connected to said top cap; (g) a quantity of regenerative anion exchange resins and a quantity of regenerative cation exchange resins disposed within said second compartment for softening and dealkalizing the water flowing through said second compartment; (h) first screen means for segregating said first and second compartments; (i) an outlet compartment for receiving the water from said second compartment and directing the water to said discharge pipe said outlet compartment being defined by a bottom cap sealingly connected to another end of said cylinder; and (j) second screen means for segregating said second compartment from said outlet compartment.
Claim 3
Dependent Claim 36 words
A water conditioner as set forth in claim 1 including a unit for regenerating said anion and cation exchange resins, said unit including means for selectively inserting said unit intermediate said inlet pipe and the faucet.
Claim 4
Dependent Claim 41 words
A water conditioner as set forth in claim 2 wherein said unit comprises a jar for receiving the regenerant compound, a lid and an inlet and an outlet extending from said jar for conveying water into and out of said unit.
Claim 5
Dependent Claim 35 words
A water conditioner as set forth in claim 1 wherein the diameter of said cylinder is nominally three inches and the overall height of said cylinder and top and bottom caps is nominally 17 inches.
Claim 6
Dependent Claim 21 words
A water conditioner as set forth in claim 4 wherein said cylinder and said top and bottom caps are of plastic.
