Abstract

Abstract A purification unit includes an electrolytic cell adapted to hold a body of water to be purified and provided with two electrically insulated electrodes, a pump supplying the water to be purified to the cell through a filter and driving purified water out of the unit, a power supply for supplying electrolyzing current to the electrodes, a control circuit which generates a sensible signal indicative of the operating conditions of the pump, the power supply, and the filter, and a housing which encloses the cell, the pump, the power supply, and the control circuit. The housing is partly received in a container for the raw water. The portion of the housing projecting from the container carries a discharge spout for purified water, a connector for an external source of current, and the signal display elements of the control circuit.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 215 words
A system for supplying water fit to drink comprising: (a) a container adapted to hold a body of water to be purified; (b) a housing having an intake for water to be purified; (c) fastening means releasably fastening a portion of said housing including said intake in said container for communication with said body; (d) outlet means on said housing and extending outward of said container for discharge of purified water, (1) said inlet and said outlet means defining a path for the flow of water through said housing from said inlet to said outlet means; (e) means in said housing defining a cell; (f) two electrodes spacedly mounted in said cell and electrically insulated from each other; (g) pump means mounted in said housing for conveying the water to be purified in said path from said intake through said cell to said outlet means; (h) filter means mounted in said housing and interposed in said path between said intake and said cell for removing particulate matter from said water prior to entry into said cell; (i) power supply means in said housing for supplying electrolyzing current to said electrodes; and (j) signal generating means for generating a sensible signal indicative of the operating condition of said pump means and of said power supply means.
Claim 2
Independent Claim 215 words
A system for supplying water fit to drink comprising: (a) a container adapted to hold a body of water to be purified; (b) a housing having an intake for water to be purified; (c) fastening means releasably fastening a portion of said housing including said intake in said container for communication with said body; (d) outlet means on said housing and extending outward of said container for discharge of purified water, (1) said inlet and said outlet means defining a path for the flow of water through said housing from said inlet to said outlet means; (e) means in said housing defining a cell; (f) two electrodes spacedly mounted in said cell and electrically insulated from each other; (g) pump means mounted in said housing for conveying the water to be purified in said path from said intake through said cell to said outlet means; (h) filter means mounted in said housing and interposed in said path between said intake and said cell for removing particulate matter from said water prior to entry into said cell; (i) power supply means in said housing for supplying electrolyzing current to said electrodes; and (j) signal generating means for generating a sensible signal indicative of the operating condition of said pump means and of said power supply means.
Claim 3
Dependent Claim 30 words
A system as set forth in claim 1, wherein said signal generating means include means generating a sensible signal in response to at least partial clogging of said filter element.
Claim 4
Dependent Claim 40 words
A system as set forth in claim 2, wherein said pump means include a pump and a motor drivingly connected to said pump, the system further including means for deenergizing said motor when said operating conditions deviate from predetermined conditions.
Claim 5
Dependent Claim 50 words
A system as set forth in claim 1, wherein said housing has two parts releasably secured to each other, one part of said housing enclosing said power supply means, said signal generating means, and said cell, the other part of said housing enclosing said pump means and said filter means.
Claim 6
Dependent Claim 22 words
A system as set forth in claim 1, further comprising a one-way valve in said path between said intake and said cell.
Claim 7
Dependent Claim 21 words
A system as set forth in claim 1, wherein said outlet means includes a tubular spout pivotally mounted on said housing.
Claim 8
Dependent Claim 24 words
A system as set forth in claim 1, wherein said fastening means include threaded means securing said portion of the housing to said container.
Claim 9
Dependent Claim 41 words
A system as set forth in claim 1, wherein said housing has, a wall portion remote from said intake and outside said container, said signal generating means including signal display means mounted on said wall portion for displaying said sensible signal.
Claim 10
Dependent Claim 30 words
A system as set forth in claim 8, wherein said wall portion carries connector means for connecting said power supply means to a source of electric current outside said housing.
