A wash arm assembly may include: a wash arm having a circular opening with a center, an edge, and a mounting unit having a circular insertion portion and a supporting portion. The mounting unit may be inserted at least partly in the circular opening to mount the wash arm within the dishwasher and to allow rotation of the wash arm around a rotational axis. The insertion portion may be inserted at least partly in the circular opening to form a passage between the edge and the circular insertion portion when the mounting unit is inserted at least partly in the circular opening. The wash arm may include a protrusion, and the supporting portion and the wash arm may form a chamber delimited by the passage and the protrusion when the supporting portion supports the wash arm. A dishwasher including the wash arm assembly may also be provided.

A dishwasher includes a main body, a tub provided inside the main body and configured to form a washing chamber, a machine room formed under the tub, a drain hose configured to discharge washing water stored in the washing chamber, and a hose fixer disposed on a side surface of the tub and configured to fix at least a part of the drain hose, and the drain hose further includes a first coupler coupled to one side of the machine room and a second coupler coupled to the hose fixer, and the first coupler includes an insertion part provided to extend in a longitudinal direction of the first coupler to be inserted to the one side of the machine room to couple the first coupler to the one side of the machine room.

A minute bubble generator includes a flow path member including a flow path allowing a liquid to pass therethrough; and a colliding part provided in the flow path and generating minute bubbles in the liquid passing through the flow path by locally reducing a cross sectional area of the flow path. The colliding part is formed integrally with the flow path member and is provided closer to an upstream end or a downstream end relative to a lengthwise center of the flow path.

A retrofit auxiliary device for distributing cleaning resources to a household cleaning appliance having a treating chamber is described wherein the device can connect to various household cleaning appliances of different makes and models and can learn the flow of water and detergent during various stages of operation and then perform the dispensing itself.

A dishwasher filtration system includes a coarse filter disposed in a tub of a dishwasher, the coarse filter configured to filter water directed to a main wash pump. The system also includes a soil accumulation chamber configured to receive a portion of water from the main wash pump. The system further includes a fine filter covering an opening of the soil accumulation chamber, the fine filter configured to filter the portion of water received inside the soil accumulation chamber. The system also includes a backwash nozzle configured to supply water to the fine filter. In addition, the system may include a deflector that deflects the water from the backwash nozzle to the fine filter.

A wash arm assembly may include wash arm having a tubular connection portion and a tubular receiving means for receiving the tubular connection portion. The tubular connection portion may include a first guiding surface and a second guiding surface, and the tubular receiving means may include a third guiding surface and a fourth guiding surface. The first guiding surface may be aligned to the third guiding surface and the second guiding surface may be aligned to the fourth guiding surface when the tubular connection portion is inserted in the tubular receiving means. The first, second, third and fourth guiding surfaces may be arranged to guide the tubular connection portion and the tubular receiving means into alignment with each other upon rotation of the wash arm. A dishwasher including the wash arm assembly may also be provided.

An adjustable conduit and docking assembly for use in a dishwasher appliance is provided. The adjustable conduit and docking assembly includes a conduit configured for receiving a docking station at different heights so as to accommodate a height adjustment of a rack assembly to which the conduit is attached. The conduit and docking assembly includes a multiport docking station to provide this functionality.

A dishwasher is disclosed. The dishwasher includes a tub, a main arm and an auxiliary arm for spraying water to an object to be washed, a fixed gear unit for rotatably supporting the main arm, a rotating gear unit configured to be rotated in engagement with the fixed gear part, a link unit for allowing the auxiliary arm to perform a reciprocating rolling movement, and an auxiliary arm connection unit. The auxiliary arm connection unit includes an extension pipe, a shaft extending from the extension pipe in order to support an interior of the auxiliary arm, and a sealing member protruding from an outer circumferential surface of the extension pipe. The sealing member includes a support member provided on at least one of an upper portion of the sealing member and a lower portion of the sealing member in order to support the interior of the auxiliary arm.

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.

An inlet assembly (T) and a washing device (C), particularly a dishwasher, are provided. The inlet assembly (T) comprises at least one body (1) having a first opening (1a); a connection area (1b) on the body (1), and a hole; a cover assembly (2), at least a part of which is inserted into the body (1) through the first opening (1a), and including a cover body (2a) closing the first opening (1a), a water inlet section (2b) extending from one side of the cover body (2a), a second opening (2d) on the water inlet section (2b), allowing air to enter the water inlet section (2b), a condensation section (2e), formed as a chamber, extending into the body (1), and located on the other part of the cover body (2a), and a third opening (2f) on a part of the cover body (2a) where the condensation section (2e) is situated.
