First Claim
Patent Images
1. A method of cleaning a rotating filter located within a liquid circuit of a household appliance such that liquid flows through the rotating filter to effect a filtering of the liquid, the method comprising:
- passing of liquid through the liquid circuit of the household appliance;
rotating the filter during the passing of the liquid; and
scouring the rotating filter by introducing a granular agent into the liquid circuit during the passing of the liquid and the rotating of the filter such that the granular agent becomes entrained within the passing liquid and is carried by the passing liquid into contact with the rotating filter and where the granular agent is maintained adjacent the rotating filter during the scouring.

33. A method of cleaning a rotating filter provided within a liquid recirculation circuit of a dishwasher, with a flow diverter spaced from the filter to define a gap between the diverter and the rotating filter, the method comprising:
-
introducing a granular agent into the gap between the diverter and the rotating filter of the dishwasher; and while at least some of the granular agent resides within the gap, rotating the filter or passing liquid through the filter to effect a cleaning of the filter with the granular agent that is within the gap, wherein the granular agent cleans the filter by scouring a surface of the filter. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)

48. A method of cleaning a rotating filter located within a liquid circuit such that liquid flows through the rotating filter to effect a filtering of the liquid, the method comprising:
-
passing of liquid through the liquid circuit; rotating the filter during the passing of the liquid; scouring the rotating filter by introducing a granular agent into the liquid circuit during the passing of the liquid and the rotating of the filter such that the granular agent becomes entrained within the passing liquid and is carried by the passing liquid into contact with the rotating filter; and removing the granular agent from the liquid circuit after introducing the granular agent; wherein the granular agent comprises magnetic particles and the introducing or removing of the granular agent comprises applying or removing a magnetic field from the magnetic particles.

49. A method of cleaning a rotating filter provided within a liquid flow and the rotating filter having an upstream surface and a downstream surface relative to the liquid flow, the method comprising:
-
scouring the filter by introducing a granular agent adjacent the upstream surface during at least one of a rotating of the filter and a passing of liquid through the filter from the upstream surface to the downstream surface; removing the granular agent after the introduction of the granular agent storing the removed granular agent for reintroduction wherein the granular agent comprises magnetic particles and the introducing or removing of the granular agent comprises applying or removing a magnetic field from the magnetic particles.
