Patent ID: 7823538

Claim:
A hydration system for animals, comprising, in combination: a nested double bowl having an inner bowl and an outer bowl, and each of said inner bowl and said outer bowl having inside surfaces and outside surfaces, and said inside surface of said inner bowl spaced a preselected distance from said inside surface of said outer bowl to define a waste discharge volume therebetween, said outside surface of said inner bowl defining a water hydration volume, and each of said inner bowl and said outer bowl having an upper rim edge and a lower rim edge, and said upper rim edge of said outer bowl and said upper rim edge of said inner bowl defining first preselected geometrical configurations having first areas and said lower rim edge of said outer bowl and said lower rim edge of said inner bowl defining second preselected geometrical configurations having second areas, and said first preselected areas are greater than said second preselected areas, and said nested bowl having a central axis perpendicular to said first preselected area and said second preselected area; said lower rim edge of said inner bowl in close proximity to said lower rim edge of said outer bowl; a top edge member mounted between said upper rim edge of said inner bowl and said upper rim edge of said outer bowl and said top edge member having a plurality of water flow passages providing water flow passages into said waste discharge volume therethrough; said inner bowl having a plurality of water drain flow passages in regions adjacent said upper rim edge to provide water flow passages from said hydration volume into said waste discharge volume; a plurality of fins mounted on said inner surface of said outer bowl and extending a predetermined distance from regions adjacent said lower rim edge of said inner surface of said outer bowl toward said upper rim edge thereof; a plurality of waste discharge ports at said lower rim edge of said outer bowl for providing waste water flow passages from said waste discharge volume to regions external said outer bowl; a water flow manifold in said second preselected areas of said lower rim edges of said inner bowl and said outer bowl and said water flow manifold having an inlet water aperture providing water flow communication from regions external said hydration system to an interior face of said water flow manifold in said water hydration volume of said inner bowl; a vortex cap mounted on said water flow manifold in said water hydration volume in water receiving relationship to said inlet water aperture of said water flow manifold, and said vortex cap having forced vortex slots therein providing water flow communication between said inlet water aperture and said hydration volume and oriented at a preselected forced vortex generating angle with respect to said hydration volume.
