Abstract

The present invention comprises a water spout for a sink, bathtub or the like, for providing a sheet-like flow of water. The spout has an inlet with a central longitudinal axis and an inlet cover disposed within the spout for directing inflowing water away from the central longitudinal axis into a first chamber. The top of the first chamber is defined, at least in part, by a substantially horizontal baffle which preferably extends from the front of the spout to a point proximate the rear wall of the spout leaving a gap between the rearward edge of the baffle and the rear wall of the spout. A second chamber, preferably having a volume greater than the volume of the first chamber, is disposed above the substantially horizontal baffle. The water exits the spout through a mouth which is fluidic communication with the second chamber. The mouth is most preferably in fluidic communication with a forward position of the second chamber at a point higher than the rearward edge of the baffle. In this manner, water must, at least initially, flow upwardly in the second chamber before exiting the mouth of the spout.

Dependent claims

A water spout for creating a sheet-like water flow comprising:

a rear wall, a spout cover coupled to said rear wall, said spout cover having a top wall and a forward wall;
a substantially planar baffle extending substantially horizontally from said forward wall to a position proximate said rear wall and terminating in a rear edge thereby forming a gap between said rear wall and said rear edge, said rear edge of said baffle being substantially flat in cross-section;
a first fluid chamber defined at least in part by said rear wall and a bottom side of said baffle;
a second fluid chamber defined at least in part by said rear wall and a top side of said baffle, said second chamber having a volume larger than the volume of said first chamber, said second chamber including a surface on said forward wall which slopes upwardly in the direction of water flow from said gap;
an inlet having an opening in said first chamber and a central longitudinal axis extending towards said forward wall;
an inlet cover positioned proximate said inlet for diverting inflowing water away from said longitudinal axis in a lateral direction into said first chamber;
and
a downwardly facing elongated outlet in said forward wall open to said second chamber for directing water out of said second chamber, said outlet disposed at a position higher than said rear edge of said baffle.
