Definitions

  • the invention relates to a cleaning device and a method for cleaning items to be cleaned.
  • Cleaning devices and methods of the type mentioned can be used, for example, in the field of dishwashing technology, in particular in the field of commercial dishwashing technology.
  • the invention can thus be used in particular in canteen kitchens in which items to be cleaned, for example trays, dishes and cutlery, have to be cleaned in large quantities.
  • other areas of application are also conceivable in principle.
  • a large number of cleaning devices also known as cleaning devices, are known from the prior art, which can clean and / or disinfect items to be cleaned.
  • the design of these cleaning devices depends largely on the various boundary conditions, such as, for example, the type of items to be cleaned, the contamination, the throughput or similar conditions.
  • cleaning devices which are described, for example, in DE 10 2004 056 052 A1 or in DE 10 2007 025 263 A1.
  • cleaning devices in canteen kitchens are combined with transport devices or transport systems for automatic delivery and / or removal of the items to be cleaned.
  • cleaning systems are provided in many communal catering facilities, such as canteens in schools, hospitals or other facilities in which a large number of people are catered for, in which trays with contaminated crockery and cutlery are placed on a conveyor belt.
  • This turns the items to be cleaned into the actual tion device such as a dishwasher transported.
  • the items to be cleaned are usually still sorted using personnel, waste is disposed of, and dishes, cutlery and trays are fed to the cleaning device in a suitable manner, for example a belt conveyor dishwasher, a basket conveyor dishwasher, a hood dishwasher or a pass-through dishwasher.
  • the cleaned items to be cleaned are generally sorted manually and fed to corresponding transport devices or storage devices, such as, for example, a tray trolley or a plate trolley.
  • a technical and organizational challenge in many cases is that the contaminated cleaning items do not accumulate evenly.
  • load peaks often occur, but also times when there is little or no items to be cleaned.
  • the design of the system and the personnel planning must generally be designed in such a way that the personnel can cope with the peak loads, but this is not the case Circumstances outside the peak loads lead to insufficient utilization of the staff.
  • the personnel planning and the design of the cleaning device must therefore be oversized in many cases.
  • a dishwasher in the form of a commercial utensil or dishwasher designed as a program automat, which is designed as a hood or pass-through dishwasher and has a treatment chamber with at least one washing system designed as a recirculation system.
  • the dishwasher is assigned a loading / unloading device for preferably optionally automatically loading the treatment chamber with items to be washed and / or for preferably optionally automatic unloading of washware from the treatment chamber.
  • DE 4339111 A1 describes a dishwasher.
  • the dishes in the individual baskets are washed in cycle operation, with the circuits of the washing device only in their the respective time interval within the washing program.
  • a conveyor belt for the crockery baskets is controlled by means of appropriate switches in such a way that the crockery remains in the area of a washing zone during the washing process.
  • DE 10 2004 049 392 A 1 describes a method for transporting items to be cleaned through a continuous dishwasher and onto a continuous dishwasher.
  • the continuous dishwasher includes a washing zone, a rinse zone and a drying zone.
  • the items to be cleaned are cleaned in the washing zone, rinsed clear in the rinse zone and dried in the drying zone.
  • Transport devices are provided with which the items to be cleaned are transported in the conveying direction at the optimum transport speed for the process steps taking place in the respective zones.
  • the transport devices are often inflexible and are generally not able to adapt to the various boundary conditions, in particular to sudden load peaks, backlogs during loading or unloading, or even to changing requirements with regard to the type of soiling or the items to be cleaned.
  • peak loads therefore, as a rule, only the transport speed of the transport device can be adjusted, for example by slowing down the transport or completely stopping it. If, for example, a backlog of the cleaned items is formed at the outlet of the cleaning device, the entire cleaning system must generally be stopped.
  • These measures usually affect the entire cleaning system. Therefore, the personnel planning for many cleaning systems must still be dimensioned in such a way that it can withstand a peak load in any case. This provision of a personnel and usually also mechanical overcapacity can lead to unnecessary additional costs when purchasing and operating the cleaning device.
  • the cleaning device and the method should provide more flexible personnel planning with regard to the operating personnel and Enable more flexible design of the apparatus and preferably reduce the use of operating personnel.
