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.

An auxiliary gray water supply device captures used wash water from a commercial warewashing machine for supply to a pre-rinse station without substantial modification of the commercial warewashing machine. The captured wash water and treatment agent are delivered to a pre-rinse station for pre-rinsing of dishes that will be washed within the commercial warewashing machine.

A modular water leakage detector includes a housing that carries a plurality of water leakage sensors, an electrical water shutoff valve, and circuitry coupled thereto. In response to sensing water leakage, the circuitry actuates the valve to shut off a water supply. Detectors can communicate alarm indicating signals directly with one another. The detectors can include a wireless transmitter and communicate with a displaced alarm monitoring system.

Methods and systems for an integrated acid regeneration of ion exchange resins are disclosed for use in cleaning applications. Acid resins designed for use in a variety of cleaning application using a treated, softened, acidic water source are disclosed. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins within a cleaning application, e.g. ware wash machine, are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

A safety valve assembly for water inlet hoses of washing machines and dishwashers, of the type comprising a valve body (20) formed by an upper half-shell (91) and a lower half-shell (92), an inner shank (29) equipped with an upper part (29a) provided at a ring nut (14) for fixing to the water inlet faucet and a lower valve guide (4), wherein an axial chamber (21) is formed between the lower valve guide (4) and said shank (29) and wherein an annular chamber (22) is formed between the shank (29) and said half-shells (91,92), a membrane (3) being provided to divide said annular chamber (22) into an upper compartment (22b) and a lower compartment (22a), characterized in that it further comprises a filter (12) arranged at said upper portion (29a) of the shank (29), coupled by interlocking to a respective upper valve guide (18).

A dish washer includes a cabinet, a tub positioned inside the cabinet, a sump provided in a lower portion of the tub, a case brake provided on a side wall of the tub connected to the sump, and a filter device positioned below the tub inside the cabinet, to selectively filter or unfilter water received from a water supply source, and to supply the filtered water or the unfiltered water to the case brake, the water passed through the case brake is collected in the sump, the case brake is located higher than the sump to prevent a backflow of the water collected in the sump to the case brake.

A metering device for metering powdery or solid-like media such as detergents or disinfectants and for supplying the media in a dissolved state to a washing or cleaning system, including a support, in particular a cartridge support, to which a container, in particular a cartridge, with a powdery or solid-like medium can be attached. The support or the container includes a grid which prevents the medium from exiting the container. A spray nozzle controlled by a controller of the metering device dispenses water for solvating the medium. The medium dissolved in water and passing through the grid can be supplied to the washing or cleaning system via a supply device. The metering device also has a switching device that can be activated by the controller and has at least two different switching states for operating the spray nozzle in different operating modes.

A dishwasher includes: a tub that defines a washing compartment; a door configured to open and close the washing compartment; a dispenser disposed at the door and configured to accommodate a detergent; an exhaust disposed at the door and configured to discharge air in the washing compartment; a rack disposed in the washing compartment; a spray arm configured to spray wash water toward the rack and rotatably disposed in the washing compartment; a magnet provided at the spray arm; and a sensor disposed at the door and configured to detect a magnetic force of the magnet. The door includes a door cover disposed at a front of the door and a door liner facing the washing compartment. The exhaust and the sensor are disposed between the door cover and the door liner, and the sensor is disposed between the exhaust and the dispenser.

Disclosed herein is a dishwasher. The dishwasher includes a washing chamber, a spray unit configured to spray wash water into the washing chamber, a distribution chamber including a lower port through which wash water flows in and out, a distribution cover configured to cover the distribution chamber and including an upper port connected to the spray unit to supply the wash water in the distribution chamber to the spray unit, a guide member connected to the lower port of the distribution chamber so as to guide wash water, and a support detachably coupled to a lower side of the distribution chamber. The support includes a holder formed in a hollow shape and configured to hold one side of the guide member, and a coupler formed on the holder to fix the guide member so as to allow the guide member to correspond to the lower port through the holder.
