A dishwasher with a tub that defines a treatment chamber, a sump fluidly connected to the tub, sprayers within the treatment chamber, a drain pump fluidly connecting the sump to a discharge pipe, a water tank fluidly connected to the sump with a controllable valve, a softener, and a diverter valve fluidly connecting the sump and the sprayers.

A dishwasher including a tub; and an air brake assembly to supply water into the tub. The air brake assembly includes: an air brake case, a first flow path inside the air brake case through which water to be introduced into the air brake case flows, an air brake disposed on the first flow path and configured to prevent backflow of water, an air brake chamber configured to accommodate water flowing out of the air brake, a second flow path connecting the air brake chamber to the tub to guide water in the air brake chamber to the tub, a water tank in the air brake case to store water having passed through the first flow path, and a partition dividing the water tank from the air brake chamber so that a highest level of water stored in the water tank is higher than a height of the air brake.

The present invention relates to a dishwasher and a manufacturing method thereof. The dishwasher according to an embodiment of the present invention includes a water guide extending upward from a sump and supplying washing water to an upper nozzle and a top nozzle, and the upper pipe and the top pipe are separately provided to the water guide, so pressure of the washing water applied to the upper pipe and the top pipe can be reduced.

The present disclosure is directed to an apparatus for rinsing and disinfecting utensils, on demand, with a controller operating the components that deliver a pre-determined volume or timed flow of water, and exposure time of sanitizer(s) to the intended objects. The spray embodiment has high performance conical spray nozzle(s) controlled by a controller that reduces water usage and that may vary depending on the viscosity of the material to be eliminated. The recirculating embodiment has a recirculating water system, with a controller operating the components that recirculate water throughout the system until the turbidity exceeds a chosen threshold, and displace with fresh water until the turbidity returns to a lower threshold. The water resumes recirculation until it again exceeds the chose turbidity threshold and the water in the system is again displaced by fresh water. Both spray and recirculating embodiments can contain multiple rinse stations.

A household appliance, such as a fabric treating appliance and/or a dish treating appliance, incorporating both a bulk dispensing system and a single-use dispensing system, with a single-use dispensing cup having an output that is selectively coupled to one of a treating chamber of the appliance or a bulk treating chemistry reservoir of the bulk dispensing system.

A household appliance includes a water inlet configured to connect the appliance to an external water supply; a pressure control device configured to prevent water entering the appliance from the water inlet from exceeding atmospheric pressure; a treatment container configured to treat household items with water; and a seal between the pressure control device and the treatment container configured to prevent gas flowing from the treatment container to the pressure control device.

The component (10) comprises a hollow body (12) having: an inlet (14, 14a, 14b), which is adapted to be connected to a source of pressurized liquid, for example the water supply network (WS); an outlet (16), adapted to deliver said liquid to a washing chamber (WC) defined by said washing tub (WT); a path (18) for the liquid, which is defined in the hollow body (12) between the inlet (14, 14a, 14b) and the outlet (16) and includes anti-return means (26, 26a) for said liquid under pressure; a passage (28), adapted to receive, at its inlet, vapor coming from the washing chamber (WC) and to discharge the vapor into the environment outside of the washing tub (WT); and a valve device (30) comprising a plug element (32), adapted to at least partially free and obstruct said passage (28).

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 spraying apparatus and a dish-washing machine. The spraying apparatus comprises: a spraying pipe, a water injection nozzle being provided on the spraying pipe; a drive mechanism, the drive mechanism comprising a driving gear and a driven gear engaging with the driving gear, and the driven gear being connected to the spraying pipe to drive the spraying pipe to rotate; a driving mechanism, the driving mechanism being connected to the driving gear to drive the driving gear to rotate. The rotation of the spraying pipe in the spraying apparatus is stable and reliable, and control precision of a spraying region is high.

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.
