Rotating filter for a dishwashing machine |
摘要 |
A dishwasher with a tub at least partially defining a washing chamber, a liquid spraying system for spraying liquid within the washing chamber, a liquid recirculation system defining a recirculation flow path, and a liquid filtering system. The liquid filtering system includes a rotating filter disposed in the recirculation flow path to filter the liquid. |

1. A method of operating a dishwasher comprising a washing chamber holding utensils for washing, sprayers for spraying liquid on the utensils, and a liquid recirculation system, for recirculating sprayed liquid back to the sprayers, and including a filter for filtering the liquid, the method comprising:
spraying liquid within the washing chamber; recirculating the sprayed liquid for subsequent spraying; providing a filter within the recirculating liquid where the filter completely fluidly divides the recirculating liquid such that the filter has an upstream surface confronting unfiltered liquid and a downstream surface confronting filtered liquid; providing an artificial boundary spaced apart from at least a portion of the upstream surface to form a gap between the artificial boundary and the upstream surface; and rotating the filter within the liquid during the recirculating of the liquid; wherein the liquid passing between the artificial boundary and the rotating filter caused by rotation of the filter applies a shear force on the upstream surface that is greater than the liquid in an absence of the artificial boundary and aids in a removal of soils on the upstream surface. |
