Abstract

An additive dispensing arrangement for a washing machine, including removably mounting the dispenser above the filter pan, whereby the peripheral wall of the filter pan is utilized as a holding means in transferring the additive from the dispenser to the clothes washing receptacle.

Claims

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.

2. 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 retaining cavity; and

an additive storage container mountable on the filter pan above the recirculation flow and having a channel section formed to receive said additive and an outlet disposed above said channel for discharging the additive into said filter pan retaining cavity substantially only during the high speed extraction operation following said slow speed operation;

whereby said filter pan retaining cavity 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.

3. 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 above the recirculation 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 following said slow speed operation;

said peripheral wall being provided with inwardly projecting holding means for receiving and holding the additive during the extraction operation and releasing the additive to filter into the wash tub at the termination of the extraction operation.

4. An additive dispenser for an automatic fabric washer of the 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 mountable on the upper portion of the agitator for movement therewith and having an impervious peripheral wall; and

an additive storage container mounted on the filter pan 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 cavity during the high speed extraction operation;

said container including circumferentially disposed detent means cooperating with the peripheral wall of said filter pan for holding said container on said filter pan for rotation with said filter pan during said extraction operation;

said peripheral wall being provided with inwardly projecting holding means for receiving and holding the additive during the extraction operation and releasing the additive to filter into the wash tub at the termination of the extraction operation.

5. In a fabric washing machine adapted to operate through a cycle of operations including a washing operation, an extraction operation, a rinsing operation and a second extraction operation, a rotatable receptacle to receive liquid and fabrics to be washed in the liquid;

an agitator mounted within said receptacle;

drive means for driving said agitator for washing fabrics and rotating said receptacle and agitator to centrifugally extract liquid from the fabrics, an open top filter pan mounted on the upper portion of said agitator for movement therewith;

an additive dispensing arrangement including;

an additive stOrage container removably mounted on said filter pan, said container including a channel section formed therein to receive said additives;

said container including circumferentially disposed detent means cooperating with the peripheral wall of said filter pan for holding said container on said filter pan for rotation with said filter pan during said extraction operation; and

outlet means disposed above said channel section for discharging said additive during said extraction operation;

said filter pan including an impervious peripheral section having inwardly projecting retaining means for receiving and holding said rinse additive during said extraction operation and enabling said additive to filter into said receptacle at the termination of said extraction operation.
