A beverage container washing system may utilize a heated wash fluid circulation system to circulate wash fluid retained in a line between a tank and a sprayer to enable fluid that is supplied to the sprayer to be maintained at a suitable temperature for washing and/or sanitizing a beverage container, and in many instances regardless of the amount of time between wash cycles.

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 for treating dishes includes a tub at least partially defining a treating chamber, a spraying system having a manifold with at least one sprayer for spraying wash liquid into the treating chamber, and a recirculation system for recirculating liquid sprayed in the treating chamber to the spraying system. The sprayer of the manifold has multiple apertures which are configured to emit liquid to different areas of the treating chamber.

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 dishwasher with a tub at least partially defining a treating chamber, a liquid spraying system supplying a spray of liquid to the treating chamber, a liquid recirculation system defining a recirculation flow path, and a liquid filtering system having a rotating filter. A chopping system is included to macerate foreign objects within the recirculation flow path and includes a blade mounted to the rotating filter.

A control method of the washing machine with the washing water recycling function, the method comprises the following steps: Step 1, after the washing stage of the washing machine, feeding washing water into the flocculation barrel, step 2, stirring, flocculating and standing for layering in the flocculation barrel, step 3, refluxing flocculated clean recycling water into the washing barrel, discharging sewage with residual floc, step 4, feeding the tap water into the washing barrel till reaching the rinsing water level, step 5, performing rinsing. In the step 4, before feeding tap water into the washing barrel, it is determined whether or not the washing water inside the washing barrel reaches the rinsing water level L.sub.4. If yes, executing step 5. If no, executing step 4 until the rinsing water level L.sub.4 is reached.
