A cleaning apparatus for cleaning articles to be cleaned includes at least one cleaning chamber; at least one conveying device configured to convey the articles to be cleaned in a conveying direction through the cleaning chamber, the at least one conveying device comprising a plurality of tracks arranged side by side; at least one nozzle system configured to act upon the articles to be cleaned with at least one cleaning fluid; at least one sensor configured to detect a loading of the conveying device with articles to be cleaned; and at least one control means programmed to select at least one operating mode of the cleaning apparatus corresponding to the loading of the conveying device detected by the sensor, and to propose the selected operating mode to a user of the cleaning apparatus by providing a visual indicator on one or several tracks of the conveying device.

A dishwashing machine is used for pre-rinse operation of soiled dishes. A cavity is configured and arranged to contain the soiled dishes. A nozzle is proximate the cavity and is in fluid communication with the cavity. An accumulator pan accumulates wash and rinse water including cleaning chemicals used in a previous cycle of the dishwashing machine. A fluid passageway interconnects the nozzle and the accumulator pan. A pump directs the accumulated wash and rinse water from the accumulator pan to the nozzle via the fluid passageway for pre-rinse operation of the soiled dishes in the cavity, and the nozzle directs the accumulated wash and rinse water into the cavity with the soiled dishes to assist in removing soil from the soiled dishes prior to a wash cycle of the dishwashing machine. The wash cycle utilizes fresh wash water.

Disclosed is a cleaning device for cleaning washware. The cleaning device may be a conveyor dishwasher. The cleaning device has at least one cleaning chamber and at least one transportation device. The transportation device transports the washware through the cleaning chamber in a transportation direction. The cleaning device has at least one final-rinse nozzle system for applying at least one final-rinse fluid, in particular fresh water, to the washware. The final-rinse nozzle system has at least two final-rinse nozzle units which are arranged in different positions transverse to the transportation direction. The final-rinse nozzle units can be switched independently of one another in order to apply the final-rinse fluid to the washware in the different positions independently of one another.

The present invention relates to a dishwasher for washing the dishes and the cooking utensils by spraying washing water, and a control method thereof. The control method of a dishwasher according to an embodiment of the present invention includes: a water supply step of opening a water supply valve to supply washing water to the sump; and a variable spray step of spraying the washing water by at least one of the plurality of spray arms by changing the number of revolutions of the washing pump stepwise, so that the washing water can be sprayed evenly.

A dishwasher (1) for cleaning washware items (2) in the form of drinking vessels, in particular drinking cups, mugs, glasses or bottles, wherein the dishwasher is in particular configured as a counter module of a counter system and includes at least one and preferably exactly one treatment zone (3) with an associated placement area (4) and an associated removal area (5). The washware item to be cleaned can preferably manually be placed into the treatment zone via the placement area and the cleaned washware item can preferably manually be removed from the treatment zone via the removal area. The placement area and the removal area are disposed opposite one another with the interposition of the treatment zone. At least one bracket (15) is provided in the treatment zone for in particular releasably securing and/or positioning the washware item placed onto a placement surface (20) in the treatment zone.

Methods of dishwashing to remove soils are disclosed, including a first detergent wash step, wherein the detergent is substantially-free of water conditioning agents including polycarboxylic acid polymers and phosphonates, followed by a second step of rinsing under high temperature with a water conditioning agent, namely polycarboxylic acid polymers. The methods result in little to no precipitation forming on the treated ware due to the treating of the hard water before it contacts the alkalinity source which prevents precipitation and/or flocculation from occurring.

A commercial dishwasher includes at least one washing system for washing washware, having at least one rinsing system for rinsing the washed washware, and optionally a drying system for optimal drying of the rinsed washware. The dishwasher includes a camera system configured to capture at least one image of the washware to be treated in the dishwasher. An evaluation device is further provided, which is configured so as to create a pattern relating to the temporal usage behavior of the operator of the dishwasher, in particular in the course of a profiling process based on the captured images.

A method of cleaning dishware in a low temperature fill-and-dump dishwashing machine wherein the detergent composition doused in the wash cycle comprises sanitizer mitigator and enzymes, and the rinse cycle comprises sanitizer and rinse aid.

Methods and devices for washing and disinfecting objects in a washer-disinfector having at least one chamber. Steps include circulating water and detergent in the chamber, rinsing the objects in the chamber by spraying non-circulating pressurized water in the chamber, draining the chamber, and disinfecting the objects. The steps of rinsing the objects and draining the chamber can be performed at least partially simultaneously. The present invention allows for reduced water and energy consumption compared to prior art, while at the same time decreasing the risk for transfer of process residuals compared to when no rinsing is performed.

The present application relates to a system for dispensing a detergent solution from a solid detergent into a dishwasher said dishwasher comprising a washing chamber and being capable of performing cleaning cycles each including washing and rinsing periods; the system including a dispenser for dissolving solid detergent blocks and dispensing detergent solution, wherein the dispenser is configured to accommodate solid detergent, to be removably retrofittable into the dishwasher, and, to allow continuous release of all detergent solution as it is formed. In various applications the system may include a battery-powered control unit and a conductivity sensor, configured to measure the conductivity of the washing liquid and to provide the measured conductivity value to the control unit, said control unit is configured to process the conductivity value and to produce a signal.
