Abstract
A quiet fill water system for a washing machine comprises a washing tub having an outer wall and an entry port disposed within the outer wall and a valve having a water inlet and a water outlet. A water reservoir is coupled to the outer wall, the water reservoir having a tube entry port, a cup-shaped bottom portion and a water outlet wherein the water outlet is mated with the outer wall entry port so as to provide fluid communication between the water reservoir and the washing tub. A capillary tube having a first end, a second end and a tip portion is disposed such that the first end is coupled to the water outlet of the valve and the second end is positioned within the tube entry port so that the tip portion is disposed within the cup-portion of the water reservoir at a lower position relative to the water outlet such that a quiescent reservoir of water is formed during a fill period so as to decrease the level of noise of the fill period.
