Abstract
The present invention provides a pump plate (60) for conditioning the flow of a fluid before the fluid enters an inlet (51) of a circulation pump (50) of a dishwasher. The pump plate (60) may have a plate portion with a number of holes (62) dispersed across its surface such that fluid may flow through the holes (62). The pump plate (60) may also include one or more upper guide vanes (63) extending outwardly from the plate portion and configured to reduce the turbulence in the fluid flow. A dishwasher (10) including a pump plate (60) and a method for manufacturing such a dishwasher are also provided. A dishwasher (10) that includes a pump plate (60) to condition the fluid flow within the dishwasher may be configured to function efficiently while requiring less water to complete a rinse or wash cycle than a dishwasher that does not include a pump plate.
