Claims
- 1. In an automatic washer having a cycle control timer and an additive dispensing system including a multi-compartmented dispenser, a liquid flow diversion arrangement having a liquid diverter for selectively diverting liquid into preselected dispenser compartments for flushing the additives into the washer at predetermined times during a cycle of the washer, the liquid diverter having a main inlet for liquid to enter, a liquid outlet providing a plurality of exit paths for the liquid, and at least two control ports respectively coupled to ambient, the arrangement further including means responsive to the timer for selectively closing each of the control ports respectively from ambient at predetermined times for determining through which exit path and thereby into which dispenser compartment liquid entering the main inlet will emerge, and a chamber coupled respectively between each control port and its respective closing means for accumulating liquid emerging from the control ports, the chambers being dimensioned for preventing audible sonic oscillations in the liquid flow diversion arrangement, wherein the improvement comprises:
- a hose associated respectively with each chamber for draining liquid accumulating therein, the hose being dimensioned to act as a closed valve with respect to the control port, while allowing liquid to drain automatically from the chamber when a sufficient head has been built up therein.
- 2. In the automatic washer of claim 1 wherein the liquid diverter is the transverse pressure differential type.
- 3. In the automatic washer of claim 1 wherein a ball check valve is associated with each control port respectively to help prevent the emergence of liquid from the control ports.
- 4. In the automatic washer of claim 1 wherein there is a pair of control ports and means coupling the ports respectively to ambient adjacent the timer.
- 5. In the automatic washer of claim 1 wherein each hose is coupled respectively with each chamber at the bottom thereof for draining liquid accumulating therein.
