Abstract: An ice dispenser includes an ice storage bin with a drive shaft aperture and an ice dispensing aperture; an ice dispensing chute connected to the storage bin in proximity to the ice dispensing aperture; a paddlewheel inside the storage bin; and a drive mechanism, including a drive shaft passing through tile drive shaft aperture, for rotation of the paddlewheel. The drive shaft is connected to tile paddlewheel in such a fashion that the paddlewheel is prevented from disengaging from the drive shaft during normal operation of the ice dispensing apparatus, but the drive shaft can be disengaged from the paddlewheel in order to be able to remove the drive mechanism from the ice dispenser without accessing the ice storage bin.

The paddlewheel may be molded plastic, and include a rigid coupler molded into the paddlewheel having first and second axial openings at opposite ends for receiving the drive shaft and the agitator shaft.

Abstract: A spray-arm assembly comprises a convergent base section having a bell mouth, a throat section, and a cylindrical housing that extends axially along the periphery of the throat section, a lower cylindrical conduit section and an upper cylindrical conduit section, and a divergent diffuser section having an entry area and an exit area. In one embodiment of the instant invention, a drainage groove is disposed within the diffuser section in order to facilitate the drainage of excess water from the spray-arm assembly once a washing or rinsing phase of operation is completed. In another embodiment of the instant invention, at least one drainage notch is formed at the mouth of the divergent diffuser section in order to create a drainage passage between the divergent section and the convergent base section.
