Disclosed herein is a dishwasher capable of supplying wash water to dishes stored in a case to remove contaminants from the dishes. The dishwasher includes a case providing a washing space and having an opening surface, a rack provided in the case to provide a storage space for washing objects, a door for opening and closing the opening surface to withdraw the rack from the case, and an injection section provided in the case to spray wash water toward the rack.

A lower rack assembly for a dishwasher appliance includes a lower rack and a lift assembly connected to the lower rack. The lift assembly includes a gear assembly that includes an output spur gear and an input drive gear, and includes a first arm extending between a first end and a second end, the first end of the first arm pivotally coupled to the lower rack, the second end of the first arm coupled to the output spur gear. Movement of the input drive gear causes movement of the lower rack along the transverse direction between a retracted position wherein the lower rack is within the wash chamber and an extended position wherein the lower rack is positioned outside of the wash chamber and along the vertical direction between a lowered position and a raised position wherein the raised position is above the lowered position along the vertical direction.

A dishwasher for treating dishes according to a cycle of operation includes a tub at least partially defining a treating chamber, a liquid supply conduit, and a rotatable sprayer that is rotatable about a rotation axis and has an inlet and multiple nozzles collectively forming an outlet. The dishwasher further includes a hydraulic drive fluidly coupling the liquid supply conduit to the rotatable sprayer. The hydraulic drive is mechanically coupled to the rotatable sprayer.

A warewash machine arm mechanism includes a liquid supply shaft assembly including a rotatable sleeve bearing mounted thereon, and an arm assembly including an elongated interior liquid flow space along an arm body and one or more liquid ejection orifices. The arm assembly is releasably mounted to the supply shaft assembly via a latch mechanism of the arm assembly that engages the rotatable sleeve bearing such that the arm assembly rotates with the rotatable sleeve bearing during ejection of liquid from the liquid ejection orifices.

The present application discloses a water spraying pipe and a cleaning apparatus. The water spaying pipe includes a pipe body having a water inlet end and defining a water spraying hole in a pipe wall thereof; and a water spraying groove defined in the water spraying pipe at a position corresponding to the water spraying hole. The water spraying hole is in communication with the water spraying groove, and a diameter of the water spraying hole is greater than a width of the water spraying groove. The present application effectively improves the cleaning efficiency of the water spraying pipe.

A dishwasher includes a dishwasher cavity configured to receive an item to be washed. A water feed extends completely or partially in the dishwasher cavity for providing a water distribution in the dishwasher cavity. Associated with the water feed is a lighting device having a lighting line extending along a guiding direction of the water feed.

An artificial intelligence dishwasher including a dish rack on which dishes are arranged, a spray nozzle configured to spray washing water toward the dishes, a washing pump configured to feed washing water stored in a sump to the spray nozzle, a washing motor configured to drive the washing pump, a camera configured to capture the dish rack to obtain a dish arrangement image, and a processor configured to provide the dish arrangement image to a dish recognition model to obtain dish information included in the dish arrangement image, determine a washing cycle for the dishes based on the dish information, and control driving of the washing motor according to the determined washing cycle is provided. A dishwashing method is also provided.

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. The beverage container washing system may include a pop-up ultraviolet sanitizer that may be used to sanitize an interior of a beverage container by extending into an opening of the beverage container and emitting ultraviolet light onto an interior surface of the beverage container.

A dishwasher, dishwasher sprayer, and method of spraying utilize a tubular spray element with multiple selectable spray patterns that can be used during a wash cycle. In some instances, multiple selectable spray patterns may be supported through the use of a multi-walled tubular spray element having concentric wall sections that are movable relative to one another to selectively activate one or more apertures and thereby modify a spray pattern emitted by the tubular spray element. In other instances, multiple selectable spray patterns may be supported through the use of a multi-chamber tubular spray element in which different sets of apertures are in fluid communication with different chambers in the tubular spray element and flow is selectively controlled to one or more of the chambers.

A dishwasher including a nozzle capable of widening an injection region of washing water includes a main body, a washing tub provided inside the main body, and a nozzle configured to inject washing water into the inside of the washing tub, wherein the nozzle includes an injection port through which the washing water is injected, a guide portion configured to spirally guide the washing water injected through the injection port, and a leg portion configured to connect the guide portion and the injection port.
