Abstract
Abstract A water inlet nozzle is mounted to a clothes washer so that water exiting therefrom during the spray rinse cycle is directed onto a load of clothes which has circumferentially accumulated near the bottom of the wash basket during the drain and spin cycle. The water inlet nozzle has an upper member joined to a lower member which forms a dispersion chamber therebetween. The lower member includes an inclined bottom wall which tends to cause water flowing into the inlet nozzle to disperse laterally. The lower member also includes a cascade portion which is curved downwardly and has a transversely convex crown formed within its radius of curvature which induces some water to flow toward the lateral side walls of the lower member. The upper member has a curved forward wall and a front lip which is angled downwardly and rearwardly. A discharge orifice is formed between the terminal edges of the cascade portion and the front lip which is narrower near its center than it is at its edges. The front lip has a radius of curvature formed therein which is larger near the front lip's center than it is near its edges so that water exiting near the edges of the discharge orifice is directed more rearwardly than the water exiting near the center of the discharge orifice thereby forming an arcuate spray pattern. The edges of the spray pattern are directed higher upon the load of clothes in the wash basket than the center of the spray pattern which assures that the clothes are rinsed as thoroughly as practically possible during the spray rinse cycle.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
247 words
In an automatic clothes washer including a perforate wash basket for carrying a laundry load which is concentrically contained within a splash tub, both housed within an outer cabinet, the wash basket having a substantially vertical side wall, a vertical axis agitator disposed within the perforate wash basket which is mechanically responsive to a drive motor, and a water supply line, a water inlet nozzle comprising: an upper member; a forward wall joined to said upper member; a front lip joined to said upper member; a lower member joined to said upper member, and forming a dispersion chamber therebetween; a discharge orifice formed between said upper and lower members; an inlet conduit connected to one of said members for allowing a flow of water to pass from the water supply line into said dispersion chamber; and said lower member including means for laterally dispersing the flow of water within said dispersion chamber so that the flow of water is relatively evenly distributed laterally when it impinges upon said forward wall of said upper member, said forward wall being constructed and arranged so that the flow of water is directed downwardly thereby impinging upon said front lip of said upper member, said front lip being adapted to direct the flow of water through said discharge orifice having a center portion and edge portions so that water exiting said edge portions is directed more rearwardly toward the side wall of the wash basket than water exiting said center portion.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
19 words
An inlet nozzle as recited in claim 1 wherein said forward wall has a constant transverse radius of curvature.
Claim 4
Dependent Claim
67 words
An inlet nozzle as recited in claim 1, wherein said front lip is angled downwardly and rearwardly toward the side wall of the wash basket, said front lip including a central portion, a first distal portion, and a second distal portion, said distal portions located one on each side of said central portion, said front lip including a terminal edge which defines part of said discharge orifice.
Claim 5
Dependent Claim
68 words
An inlet nozzle as recited in claim 3, wherein said front lip has a transverse radius of curvature which is larger near said central portion that it is near said distal portions so that the water which impinges upon said distal portions is directed more rearwardly toward the side wall of the wash basket when exiting said discharge orifice than the water which impinges upon said central portion.
Claim 6
Dependent Claim
26 words
An inlet nozzle as recited in claim 4 wherein said transverse radius of curvature uniformly decreases in size from said central portion to said distal portions.
Claim 7
Dependent Claim
55 words
An inlet nozzle as recited in claim 3, wherein said lower member includes a terminal edge which defines part of said discharge orifice, said discharge orifice being narrower near its center portion than it is near its edge portions so that a taper is formed from each of said edge portions to said center portion.
Claim 8
Dependent Claim
21 words
An inlet nozzle as recited in claim 6, wherein said tapers are uniform from said center portion to said edge portions.
Claim 9
Dependent Claim
45 words
An inlet nozzle as recited in claim 1, wherein said lateral dispersing means includes a bottom wall being upwardly inclined from said inlet conduit toward said forward wall of said upper member, said inclined bottom wall situated downstream from and contiguous to said inlet conduit.
Claim 10
Dependent Claim
70 words
An inlet nozzle as recited in claim 8, wherein said lateral dispersing means further includes a cascade portion situated downstream and contiguous to said inclined bottom wall, said cascade portion being curved downwardly and having a transversely convex crown which forms a shallow "v" for inducing water flow toward said edge portions of said discharge orifice, said cascade portion having a terminal edge which defines part of said discharge orifice.
Claim 11
Dependent Claim
60 words
An inlet nozzle as recited in claim 9, wherein said front lip is angled downwardly and rearwardly, said front lip portion including a central portion, a first distal portion, and a second distal portion, said distal portions located one on each side of said central portion, said front lip including a terminal edge which defines part of said discharge orifice.
Claim 12
Dependent Claim
33 words
An inlet nozzle as recited in claim 10, wherein said front lip portion has a transverse radius of curvature which is larger near said central portion than it is near said distal portions.
Claim 13
Dependent Claim
26 words
An inlet nozzle as recited in claim 11, wherein said transverse radius of curvature uniformly decreases in size from said central portion to said distal portions.
Claim 14
Dependent Claim
19 words
An inlet nozzle as recited in claim 8, wherein said forward wall has a constant transverse radius of curvature.
Claim 15
Dependent Claim
41 words
An inlet nozzle as recited in claim 10, wherein said discharge orifice is narrower near its center portion than it is near its edge portions so that a taper is formed from each of said edge portions to said center portion.
Claim 16
Dependent Claim
