Abstract: A conveyor dishwasher includes at least one wash zone and at least one final rinse zone, wherein the at least one wash zone is designed to spray wash liquid, wherein the wash liquid is, at least proportionally, liquid which has already been used for final rinsing in the at least one final rinse zone and to which a wash chemical is added in a metered manner or is fresh water to which a wash chemical is added in a metered manner, wherein the conveyor dishwasher has a metering pump for adding the wash chemical in a metered manner to the liquid to be sprayed in the at least one wash zone, and wherein a controller is associated with the conveyor dishwasher in order to actuate the metering pump and a wash pump or final rinse pump of the dishwasher.

Abstract: Conveyor-type dish washer and method of operating it, wherein during a final-rinse operation at least from one side, preferably from each the two sides, of the items to be cleaned, at least two final-rinse liquid spray jets are sprayed in different directions in relation to each other, wherein at least one final-rinse liquid spray jet is inclined in the direction of the movement of a dish carrier and at least another final-rinse liquid spray jet is inclined against the direction of the movement of the dish carrier.

Abstract: In a dish carrier for dishwashers, in addition to lower supporting surfaces (8) and upper supporting surfaces (10), at least one upper extra supporting surface (34) which is offset forwards and/or upwards relative to the upper supporting surfaces is provided in compartments (22) for accommodating items (12, 14) to be washed in order to hold relatively flat items to be washed, for example trays (14), approximately parallel to deeper items which are to be washed, for example soup plates (12).

Abstract: Spray pipe of a conveyor ware washer for spraying items to be washed with liquid, comprising a plurality of nozzles, which are arranged one behind another in the longitudinal direction of the pipe, and an inlet, from which liquid can flow in the longitudinal direction of the pipe to the nozzles, characterized in that, at least in the case of two nozzles one following another in the liquid supply direction, the nozzle located closer to the inlet has a nozzle opening with a larger opening cross section than the nozzle adjacent to it further away from the inlet.

Abstract: A dishwasher (60) spray nozzle (20) is arranged on an outer surface (34) of a spray system (22) for discharging a spray jet (28). The outlet opening of the spray nozzle (20) has a constriction (26, 40) in a central region of its longitudinal extent.

Abstract: Conveyor-type dish washer and method of operating it, wherein during a final-rinse operation at least from one side, preferably from each the two sides, of the items to be cleaned, at least two final-rinse liquid spray jets are sprayed in different directions in relation to each other, wherein at least one final-rinse liquid spray jet is inclined in the direction of the movement of a dish carrier and at least another final-rinse liquid spray jet is inclined against the direction of the movement of the dish carrier.

Abstract: A conveyor-type dish washer and a method of operating it, characterised in that a final-rinse operation is executed with the consumption of final-rinse liquid of 3 l/m2 movement of the horizontal take-up plane of a dish carrier or less, preferably of 1 l/m2-2.5 l/m2, while the items (154, 156) which are to be finally rinsed are being subjected to final-rinse liquid spray jets; wherein said take-up plane is the horizontal area of the dish carrier where the dish carrier can take up items to be cleaned.

Abstract: Spray pipe of a conveyor ware washer for spraying items to be washed with liquid, comprising a plurality of nozzles, which are arranged one behind another in the longitudinal direction of the pipe, and an inlet, from which liquid can flow in the longitudinal direction of the pipe to the nozzles, characterized in that, at least in the case of two nozzles one following another in the liquid supply direction, the nozzle located closer to the inlet has a nozzle opening with a larger opening cross section than the nozzle adjacent to it further away from the inlet.

Abstract: Conveyor-type dishwasher comprising a conveying apparatus having compartments which extend transverse to the conveying direction and serve to hold items to be washed. A rinse zone has at least one transversely directed lateral spray nozzle on at least one side each for spraying rinsing liquid onto the item to be washed. Furthermore, a sensor apparatus for items to be washed is provided for detecting empty compartments from among the large number of compartments of the conveying apparatus. A control apparatus is provided to automatically switch off the supply of rinsing liquid to at least some of the lateral spray nozzles of the rinse zone as a function of detected empty compartments, and to automatically switch on the supply of rinsing liquid to at least some of the lateral spray nozzles as a function of detected compartments which contain items to be washed.
