Patent Images
1. An additive dispenser for an automatic fabric washer of the water recirculation type having an agitator vertically mounted in the wash tub and means for driving the agitator through a cycle of operations including a slow speed operation followed by a high speed extraction operation followed by a slow speed operation;
- the additive dispenser comprising;
a filter pan to receive the recirculation water, said pan being mountable on the upper portion of the agitator for movement therewith and having an impervious peripheral wall; and
an additive storage container mountable on the filter pan out of the path of the recirculating water flow and having a channel section formed therein to receive said additive and an outlet disposed above said channel for discharging the additive into said filter pan and against said peripheral wall substantially only during the high speed extraction operation;
whereby said peripheral wall receives and holds the additive during the extraction operation and releases the additive to filter into the wash tub at the termination of the extraction operation.
