Fluid Mechanics and Its Applications

A compact and shallow rinse agent dispenser is removably assembled upon the top of an agitator in an automatic clothes washing machine for dispensing a liquid product upon completion of a spin cycle of the washing machine. An annular, wave dampening baffle is fixed inwardly adjacent the rim of a receptacle cup in which the liquid product is initially placed. The baffle is vertically slotted and limits splashing of the liquid into a dispensing chamber or through filling ports in the cover of the dispenser during the agitation cycle, prior to spin. The discharge chamber to which liquid is passed during the spin cycle has a number of impeller vanes fitted adjacent radially-inwardly-disposed discharge openings therein to minimize loss of liquid during start-up stages of the spin cycle, when centrifugal forces alone are insufficient to confine the liquid to the outside of the chamber.
