Abstract
A liquid filtering system for a dishwasher, having a housing defining a filter chamber and configured to be fluidly coupled to a recirculation flow path of the dishwasher, a filter located within the filter chamber and having a first end axially spaced from a second end and defining a filter there between that has a first surface and a second surface, the filter being positioned within the recirculation flow path to filter soils from liquid flowing through the recirculation flow path as the liquid passes through the filter and a flow diverter to aid in cleaning the filter.
Claims20
A liquid filtering system for a dishwasher, the liquid filtering system comprising:
- a housing defining a filter chamber and configured to be fluidly coupled to a recirculation flow path of the dishwasher;
- a filter located within the filter chamber and having a first end axially spaced from a second end and defining the filter there between having a first surface and a second surface, the filter being positioned within the recirculation flow path to filter soils from liquid flowing through the recirculation flow path as the liquid passes through the filter;
- and
- a flow diverter spaced apart from one of the first surface or the second surface to define a gap through which at least some of the liquid passes as the liquid flows through the recirculation flow path and where the flow diverter is shaped such that it includes multiple segmented portions extending along at least a portion of a length of the filter;
- wherein at least one of the filter and the flow diverter are configured to rotate within the housing and wherein liquid passing between the flow diverter and the filter applies a greater shear force on the at least one of the first surface or second surface than liquid in an absence of the flow diverter.
