A clutch assembly includes a drive shaft extending along an axial direction, and an output component, the output component defining a central opening in which the drive shaft is inserted. The clutch assembly further includes a clutch selectively coupling the output component to the drive shaft. The clutch includes a cavity defined in the output component and in communication with the central opening. The clutch further includes a bearing disposed within the cavity, the bearing movable within the cavity between a first position and a second position. The bearing is spaced from the drive shaft in the first position. The bearing contacts an inner surface of the output component defining the cavity and contacts the drive shaft to transfer rotational motion from the drive shaft to the output component in the second position.

A dish washer includes a cabinet, a tub positioned inside the cabinet, a sump provided in a lower portion of the tub, a case brake provided on a side wall of the tub connected to the sump, and a filter device positioned below the tub inside the cabinet, to selectively filter or unfilter water received from a water supply source, and to supply the filtered water or the unfiltered water to the case brake, the water passed through the case brake is collected in the sump, the case brake is located higher than the sump to prevent a backflow of the water collected in the sump to the case brake.

A fluid circulation system for dishwasher appliances includes a sump and a pump. The fluid circulation system further includes a filter at least partially disposed within a chamber of the sump and surrounding an impeller of the pump. The fluid circulation system includes a diverter. The fluid circulation system further includes a cleaning manifold disposed proximate an outer surface of a sidewall of the filter, the manifold defining a plurality of apertures for flowing fluid towards the outer surface of the sidewall of the filter.

A dishwasher with a tub at least partially defining a washing chamber, a liquid spraying system, 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.

A dishwasher with a tub at least partially defining a washing chamber, a liquid spraying system, 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.

Dishwashing machine including an outer casing with an inner washing cavity adapted to accommodating a dishwasher rack. A catchment sink assembly is located on the bottom of the inner washing cavity to collect and accumulate liquid trickling down from the dishwasher rack momentarily located above the catchment sink assembly. The catchment sink assembly includes a basin-shaped catchment tank. A cup-shaped drain sump extends downwards from the bottom of the catchment tank and directly communicates with the inside of the catchment tank to receive washing or rinsing liquid arriving on the bottom of the catchment tank. A tubular member communicates with the catchment tank and is detachably fitted into a corresponding tubular outlet portion in the drain sump to divide the inner volume of the drain sump into a first inner-volume portion directly connected to a water drain line, and a second inner-volume portion directly connected to the suction of the pump.

A washing appliance includes a treating chamber, a sprayer emitting liquid into the treating chamber, and a recirculation circuit including a centrifugal separator and an electrocoagulation unit both fluidly coupled to the recirculation circuit.

A dishwasher appliance includes a tub defining a wash chamber with a sump positioned at a bottom of the wash chamber for receiving fluid from the wash chamber. A filtering system is positioned between the wash chamber and an outlet of the sump portion. The filtering system includes a first filter and a second filter. The second filter includes a hollow annular base portion and a filter body extending between the base portion and the first filter. The second filter also includes a plurality of nozzles circumferentially arranged about the hollow annular base portion, each nozzle of the plurality of nozzles in fluid communication with the hollow annular base portion and oriented towards the filter body for cleaning the filter body. An inlet in fluid communication with the hollow annular base portion may also be provided.

A fluid circulation assembly for a dishwasher appliance includes a motor with a drive shaft rotatably coupled to the motor. An impeller is coupled to the drive shaft with a one-way clutch. The one-way clutch includes a housing integrally formed in the impeller and a bearing disposed within the housing. The bearing is movable within the housing between a first position and a second position. The bearing is spaced from the drive shaft in the first position, and the bearing operatively engages the housing and the drive shaft to transfer rotational motion from the drive shaft to the impeller in the second position.

A dishwasher with a tub at least partially defining a treating chamber, a liquid spraying system, a liquid recirculation system defining a recirculation flow path, and a liquid filtering system. The liquid filtering system includes a rotatable filter disposed in the recirculation flow path to filter the liquid and a diverter overlying and spaced from at least a portion of the upstream surface to form a gap there between.
