A dishwasher and method for operating the same utilize a rack-mounted rotatable conduit incorporating a keyed connector disposed at an end thereof and configured to mate with a rotatable docking port disposed on a wall of a wash tub at a predetermined angular relationship when the rack is in the washing position such that rotation of the rotatable docking port causes rotation of the rotatable conduit.

A household dishwasher includes a washing compartment and a spray device arranged inside the washing compartment and configured to spray washing liquor and/or clean water within the washing container. The spray device includes a cage and a rotary element which is mounted in the cage for rotation about an axis of rotation. The rotary element includes a bearing surface which is radially distanced from the axis of rotation and extending around the axis of rotation for enabling the rotary element to be mounted rotatably in the cage.

A dishwasher and method for operating the same utilize a diverter valve to control via rotation the flow of fluid such as wash fluid or pressurized air to a rotatable conduit supported in the rack of a dishwasher. A valve member may be disposed at a predetermined rotational position about an axis of rotation of the conduit such that a fluid inlet on a rotatable valve body may be rotated to the predetermined rotational position to restrict fluid flow to the conduit.

A dishwasher includes an image-based detergent sensor that in some instances is configured to sense a type of detergent for use in optimizing a wash cycle based upon the type of detergent, and that in some instances is configured to direct one or more controllable sprayers to facilitate dissolution or mixing of detergent into a wash fluid during a wash cycle.

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 household dishwasher includes a dishwasher cavity and a spray arm designed to supply wash liquor and/or freshwater to dishware received in the dishwasher cavity. The spray arm includes an extension arm which is actively driven by a drive element, and a spray arm satellite which is mounted on the extension arm for rotation about an axis of rotation and includes spray nozzles supplied with wash liquor and/or the freshwater and designed to exit spray jets which rotate the spray arm satellite. The spray nozzles are designed so that force vectors resulting from the exiting spray jets mutually cancel out one another on a plane oriented perpendicularly to the axis of rotation.

The dishwasher includes a cabinet provided with a washing space inside thereof, and a nozzle unit for spraying washing water into the washing space. The nozzle unit includes a first unit body and a second unit body. Any one of the first and second unit bodies includes a first coupling rib formed along at least a portion of the periphery and a second coupling rib spaced apart from the first coupling rib by a predetermined distance. The other of the first and second unit bodies includes a third coupling rib inserted between the first and second coupling ribs and a second coupling rib located inside the third coupling rib, and stepped ribs configured to face each other.

A dish washer and a control method are disclosed. The dish washer includes a sump and at least one nozzle configured to inject water. The dish washer also includes a distributor configured to receive water of the sump and distribute the water to the at least one nozzle. The dish washer also includes a reservoir configured to receive and store the water of the sump. The dish washer also includes a circulation path configured to connect the sump and the distributor. The dish washer also includes an inflow path configured to branch off from the circulation path to supply the water of the sump to the reservoir. The dish washer also includes a first valve configured to open or close the inflow path and a second valve configured to open or close the outflow path, and the outflow path is configured to flow the water out of the reservoir.

A dishwasher includes a case, a sump connected to an inside of the case and collecting washing water, a washing pump receiving washing water from the sump and generating steam, and a steam nozzle connected to the washing pump and spraying steam to the inside of the case. The steam nozzle includes a steam nozzle body having a steam inlet and including a steam accommodating portion accommodating steam therein, a first steam sprayer provided in the steam nozzle body and spraying steam to the inside of the case, and a second steam sprayer provided in the steam nozzle body and disposed at a position farther from the steam inlet than the first steam sprayer, wherein a tunnel flow path penetrating through a lower end of the first steam sprayer is formed to allow steam passing through the tunnel flow path to be introduced into the second steam sprayer.

A household dishwasher includes a dishwasher cavity and a spray facility arranged within the dishwasher cavity for spraying washing liquor and/or fresh water in the dishwasher cavity. The spray facility includes a nozzle for spraying the washing liquor and/or the fresh water and a spiral-shaped flow-conducting element for feeding the washing liquor and/or the fresh water to the nozzle. The spiral-shaped flow-conducting element is configured, during operation of the spray facility, to feed the washing liquor and/or the fresh water to the nozzle in such a way that the washing liquor and/or the fresh water exits the nozzle as a rotating conical spray jet.
