Abstract
A liquid swirler arranged to comminute relatively large solids so as to permit the comminuted solids to pass through openings in the swirler with a liquid flow induced therethrough. In the illustrated embodiment, the apparatus is utilized in a dishwasher having a pump for flowing dishwashing liquid through a flow passage of a centrifuge-type separator. The swirler effects a swirling movement of the liquid in the separator to permit the separator to remove the solids from the liquid before passing the liquid on to the pump. The swirler is arranged to provide the further function of breaking solids down to a small enough size to permit them to pass satisfactorily through the pump and dishwashing liquid circulation system. A resilient member is disposed adjacent the swirler to assist in breaking up relatively large solids by holding them suitably for comminuting action by the rotating swirler.
