A dishwashing appliance may include a cabinet, a tub, a sump, and a filter assembly. The tub may be positioned within the cabinet and define a wash chamber for receipt of articles for washing. The sump may be positioned at a bottom portion of the tub along a vertical direction. The sump may include an internal wall defining a collection chamber. The filter assembly may be at least partially received within the collection chamber. The filter assembly may include a top cap extending above the collection chamber. The top cap may include a fixed indicium calibrated to a predetermined fill volume of the dishwashing appliance.

A dishwasher appliance includes a drain basin defined at a bottom of a sump of the dishwasher. The drain basin defines a discharge port and a drain pump is in fluid communication with the discharge port for selectively urging a flow of wash fluid through the discharge port to an external drain during a drain cycle. A check valve assembly includes a check valve removably positioned over the discharge port between the drain pump and the drain basin and a positioning arm attached to the check valve for positioning and locking the check valve in place.

Disclosed herein is a dishwasher that includes a linear type injection structure with an easily separable filter assembly. The dishwasher includes a washing tub configured to wash dishes, a sump configured to store washing water injected toward the washing tub, and a coarse filter located at a bottom plate of the washing tub and configured to filter foreign substances included in the washing water. Here, the coarse filter includes a first coarse filter including filter holes through which the washing water that drops to the bottom plate passes, and is configured to protrude from the bottom plate of the washing tub, and a second coarse filter located below the first coarse filter.

Provided are systems, methods, and apparatus for spraying water in a dishwasher. A dishwasher may include a wash chamber and at least one dish rack. The dishwasher may include a water inlet selectively connected to a dish spray device, which may connect a dish spray conduit with the wash chamber. The dish spray device may be oriented towards the at least one dish rack, such that the spray device may be configured to direct water onto the dishes for washing. The water inlet may be selectively connected to a fill device, which may connect the fill conduit with the wash chamber. The fill device may be configured to provide water to the circulation assembly without impinging the at least one dish rack. The one or more valves may selectively direct water from the water inlet to one or both of the dish spray device and the fill device.

A sink-type washing machine comprises a case having a sink body; the sink body has a recess at least at the center of the bottom portion; a drain board having a same shape as the recess which is covered on the recess; the drain board has a plurality of drain holes; the recess under the drain board defines into a drain region; the surface of the drain board is flush with the bottom portion of the sink body around the drain board; the water pump is disposed in the drain region for pumping the water in the drain region to above the drain board. By having the water pump arranged in the drain region of the sink body, the water pump is provided with a great water replenishment effect, arrangement of a water outlet component is facilitated, and an improved spraying effect can be acquired.

A household dishwasher includes a washing container for holding a dishwasher load, a sump arranged at a bottom of the washing container, a filter system provided at the sump, and a spray arm for applying washing liquor and/or fresh water to the dishwasher load. The spray arm includes an extension piece which is mounted on the sump for rotation about a first axis of rotation and includes a filter cleaning nozzle for cleaning the filter system with the aid of the washing liquor and/or fresh water, and a spray arm satellite which is mounted on the extension piece for rotation about a second axis of rotation.

A method and apparatus for operating a food waste recycling appliance includes a food waste recycling container, a condensate reservoir, a first fluid pathway fluidly coupling the food waste recycling chamber and the condensate reservoir, and a fan moving air from the food waste recycling chamber to the condensate reservoir along the first fluid pathway to define a first airflow.

A household dishwasher includes a dishwasher cavity, and a functional region embodied in one piece with the dishwasher cavity and processed by a laser processing method.

A water filter apparatus for use in filtering particles out of a water supply is provided. The apparatus comprises a multiple layered mesh type filter housing having a top proximal end and a bottom distal end, wherein the top proximal end comprising dual projected passageways adapted to be connected with an upstream water supply and for the addition of the soap powder, solution and detergent to the upstream water prior to the filtration process, The cup or cone shaped funnel is attached, either at the side or at the top of the said top proximal end of the purifier as shown in figs. The funnel act as the passage for detergent or soap powder, mixed inside the purifier before entering the filter. The device enables the mixing of the soap powder or detergent with the upstream water prior to the process of filtration executed by the mesh arrangement. The water and soap powder combination provided in the form a powder solution is in-let into the mesh arrangement for filtration which avoids the formation of scaling in the washing machine and the formation of the white patches in the washed clothes. The filtering device comprises at least six filtering meshes of varied micron sizes sandwiched between the top proximal end and the bottom distal end. The meshes are arranged in such a fashion as to comprise the larger micron sized mesh closer to the top proximal end with correspondingly decreasing micron sized meshes to the bottom distal end. The more important aspect of the invention being that the water purifier is capable of cleaning the filter and cartridge through backwash or reverse wash process by connecting the said purifier arrangement in the upside down position to the said tap water inlet.

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.
