  • conveyor ware washer There are two types of conveyor ware washer.
  • the one type are tape washers (flight-type goods washers), in which the conveyor belt has holding elements for holding the dishes to be cleaned.
  • the other type are rack-conveyor ware washers, in which a transport mechanism transports baskets containing the dishes.
  • the conveyor belt or the transport mechanism is provided with a plurality of intermediate spaces or passage openings through which water sprayed onto the dishes can drain downwards.
  • Dishwashers are not only suitable for cleaning dishes in the form of plates, cups and bowls, but also for cleaning dishes in the form of spoons, knives and forks and for cleaning trays and for cleaning other objects used in catering establishments, especially in hotels , Restaurants and canteens.
  • the term "crockery" is used to represent all objects which can be cleaned by a dishwasher in order to simplify the description of the invention.
  • the object of the invention is to solve the problem of designing a dishwashing machine which contains at least one conveyor dishwasher in such a way that the cleaning operation of the dishes becomes more independent of the provision of water for the cleaning process.
  • the invention relates to a dishwashing machine, comprising at least one conveyor dishwasher, preferably a conveyor dishwasher or a basket conveyor dishwasher, characterized in that the at least one conveyor dishwasher is divided on a dishwashing apparatus and a spatially separate water treatment station, and that at least one recirculation circuit is formed, in which Water is recirculated from the water treatment station to the dishwashing apparatus and back again, wherein the recirculation circuit in the dishwashing apparatus has spray nozzles for spraying water onto the dishes and at least one water discharge opening for recirculating sprayed water to the water treatment station.
  • the water may be treated separately from the dishwashing apparatus, for example, cleaned, heated, pumped and / or altered by mixing different quality water and / or by mixing water with other liquids or additives.

This results in a better cleaning of the water, which in turn means that the same water can be used more frequently before it has to be replaced by fresh water. This can significantly reduce water consumption.
  • Another advantage of the invention is that all maintenance-intensive parts are no longer located in the dishwashing device, but separately in the water treatment station, which provides the water for the dishwashing. Thereby, cleaning work, maintenance, inspection and repair work at the water treatment station can be carried out without disturbing the cleaning operation in the dishwashing apparatus and without disturbing persons who use the dishwashing apparatus.
  • the water treatment station is arranged at least one floor lower than the at least one dish-washing device. This has the advantage that water sprayed in the dishwashing device can flow back by gravity into the water treatment station without the need for pumps.
