Definitions

  • the present invention is directed to a fluid dispensing unit, and more particularly, to a unit for dispensing a fluid in a sheet-like flow according to the preamble of the claim.
  • a common concern among engineers is to design a dispensing unit which is able to receive a turbulent ingress of fluid from a high pressure source and bring that turbulent flow under control in order to obtain a desired fluid flow at the point of egress from the dispensing unit.
  • a dispensing unit should therefore be designed to provide the necessary fluid control for delivering the fluid from a fluid inlet to the point of egress.
  • 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 extending towards a forward wall of the spout and an inlet cover disposed within the spout for directing inflowing water in lateral direction away from the central longitudinal axis into a first chamber.
  • the top of the first chamber is defined, at least in part, by a planar substantially horizontal baffle which preferably extends from the forward wall 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 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 in fluidic communication with the second chamber.
  • the mouth is 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 which is a downward facing elongated opening in the forward wall.
  • Figure 1 is a perspective view of one embodiment of the present invention mounted on the side of a tub which is illustrated in phantom.
  • Figure 2 is a bottom view of the spout illustrated in Figure 1.
  • Figure 3 is a rear view of the spout illustrated in Figure 1.
  • Figure 4 is a cross-sectional view taken along lines 4-4 of the Figure 3.
  • Figure 5 is a rear view of an alternative rear wall of the spout of the present invention.
  • Figure 6 is a cross-sectional top view taken along line 6-6 of Figure 5.
  • Figure 7 is a cross-sectional side view taken along line 7-7 of Figure 5.
  • the present invention comprises a water spout 10 for creating a sheet-like water flow.
  • the present invention is particularly adapted to be mounted on the side wall of a bathtub, sink or the like. While the preferred embodiment of the present invention has an elongated, arcuate mouth 15 positioned at the forward end of the spout, as shown in Figure 2, the outside configuration of the spout of the present invention is not limited to the configurations illustrated in the figures.
  • the rear wall of spout 10 is preferably provided with mounting holes 31 and 32 to allow easy mounting of spout 10 on a bathroom fixture or the like.
  • inlet 40 is centrally positioned on the rear wall 20.
  • Inlet 40 is preferably provided with an O-ring 42 for facilitating a water tight connection between inlet 40 and a water pipe (not shown).
  • a pair of side walls 23,24 are disposed to the sides of inlet 40. In the illustrated preferred embodiment of the present invention, side walls 23,24 prevent water from flowing into the area adjacent mounting holes 31,32 to minimize the risk of leaks.
  • spout 10 is formed of two separately molded elements, namely rear wall 20 and forward spout cover 50.
  • Back wall 20 and spout cover 50 may be formed of any suitable material, for example, plastic.
  • Spout cover 50 is joined with rear wall 20 in a fluid tight fashion such as by known water-tight adhesives.
  • rear wall 20 is molded integrally with inlet cover 25.
  • Spout cover 50 comprises a forward wall 60, mouth 70, upper wall 80 and an interior baffle 90.
  • Spout cover 50 is attached to rear wall 20 such that baffle 90 is positioned substantially horizontally and at a location higher than fluid inlet 40.
  • a first chamber 65 is defined at its upper limit by the bottom surface of baffle 90, and the portions of forward wall 60 and rear wall 20 disposed below the bottom surface of baffle 90.
  • baffle 90 forms a gap 95 with the rear wall 20. Gap 95 is the only place where water flows from first chamber 65 into second chamber 85.
  • the volume of second chamber 85 is greater than the volume of first chamber 65.
  • the ratio of the volume of first chamber 65 to second chamber 85 is preferably about 1:1.25 - 1:5, most preferably about 1:2. In this manner, the water spends a greater time in second chamber 85 away from the turbulent effects of inlet 40.
  • Gap 95 is preferably about 1,6 mm to 19 mm (1/16 to 3/4 inch) and most preferably about 3,2 mm (1/8 inch).
  • the illustrated preferred embodiment of the present invention is also advantageously provided with an incline disposed between mouth 70 and rear edge 91 of baffle 90, in second chamber 85.
  • water is not permitted to simply pour over rear edge 91 and out mouth 70 but is forced to spend at least some time in second chamber 85.
  • mouth 70 By positioning mouth 70 above rearward edge 91, water must remain within upper chamber 85 for at least some time facilitating the decrease in any turbulence occurring in the second chamber 85.
  • FIG. 5-7 An alternative embodiment of the back wall 120 and inlet cover 125 are illustrated in Figures 5-7.
  • the inlet cover 125 is disposed on an angle relative to back wall 120.
