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 filter device for dishwashers or washing machines comprises a filter housing, an inlet opening for raw water, and an outlet opening for clean water. The inlet opening is formed in a first housing wall. A filter for filtering the raw water is arranged downstream from the inlet opening in the flow path of the raw water. The outlet opening is formed in the first housing wall.

The stationary gasket used in all kinds of dishwashers and similar household appliances, characterized in that; it ensures the sealing not by being compressed but by stretching and ensures sealing in both ways with a single part.

A filter structure of a dishwasher and a dishwasher, wherein the filter structure of the dishwasher comprises a filter screen, the filter screen comprises several first filter ribs and several second filter ribs, and the second filter ribs and the first filter ribs are arranged to cross each other so as to form a mesh structure. The filter screen of the filter structure is a mesh structure, which does not need post-perforation, thereby saving on fabrication costs. The filter screen comprises a mesh structure formed by the second filter ribs and the first filter ribs being arranged to cross each other. Not only do the second filter ribs and the first filter ribs enhance the strength of the filter screen, but the mesh structure also prevents the occurrence of a situation in which filter pores of a metal filter screen are blocked by washing impurities.

A washing machine such as a dishwashing machine, preferably of the drawer-style or table-top style, or a laundry washing machine, the washing machine having at least one low-height wash liquid conduit connecting the outlet of a sump region of a washing tub to a wash pump. A cover plate is provided for covering a section of the washing tub base and the at least one low-height conduit is formed between the base of the washing tub and the cover plate by a combination thereof. The surface of a heating unit forms a surface of the low-height conduit and the sump is provided with multiple outlets.

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 washing machine such as a dishwashing machine, preferably of the drawer-style or table-top style, or a laundry washing machine, the washing machine having at least one low-height wash liquid conduit connecting the outlet of a sump region of a washing tub to a wash pump. The at least one low-height conduit having a transverse cross-section that is substantially oblong. In one aspect, the surface of a heating unit forms a surface of a low-height conduit. In another aspect, the sump is provided with multiple outlets. In another aspect, a cover plate is provided for covering a section of a washing tub base and the at least one low-height conduit is formed between the base of the washing tub and the cover plate by a combination thereof. In another aspect, a pump cap component is located in the washing tub, the pump cap component having upper and lower spaced walls and at least one connecting wall between the upper and lower spaced walls, the connecting wall(s) arranged so as to form a closed shape when viewed from above, the closed shape including a wash pump housing volume for an impeller of the wash pump.

A dishwasher filter device based on micro-nano aeration includes a cylinder for accommodating washing liquid and a filter unit. The filter unit is in communication with an inner cavity of the cylinder by a water inlet pipe. The filter unit is connected to a micro-nano bubble generator by a third pipe. The micro-nano bubble generator is connected to a water outlet unit. The water outlet unit includes a fourth pipe connected to the micro-nano bubble generator and a dissolved air release assembly connected to the other end of the fourth pipe. The dissolved air release assembly is disposed at a bottom of the cylinder.

Provided is a structure of a sump assembly of a dishwasher. The dishwasher includes a tub forming a washing chamber, and a sump assembly provided at a lower side of the washing chamber and configured to store washing water in the washing chamber, wherein the sump assembly includes a sump housing having a water storage chamber storing the washing water and a sidewall portion forming the water storage chamber, and a heater provided on the sidewall portion to apply heat to the washing water stored in the sump assembly. The heater includes a planar heating element, and the planar heating element provided in a cylindrical shape forms the sidewall portion.

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.
