Definitions

  • the invention relates to a cleaning system and a method for cleaning items to be cleaned.
  • Cleaning systems and methods of the aforementioned type can be used, for example, in the field of dishwashing technology, particularly in the field of commercial dishwashing technology.
  • the invention can be used in particular in commercial kitchens where items to be cleaned, such as trays, dishes, and cutlery, must be cleaned in large quantities.
  • other areas of application are also conceivable in principle.
  • cleaning devices also referred to as cleaning appliances, which can clean and/or disinfect cleaning items.
  • the design of these cleaning devices depends largely on the various boundary conditions, such as the type of cleaning item to be cleaned, the contamination, the throughput, or similar conditions. Examples include cleaning devices which, for example, are used in DE 10 2004 056 052 A1 or in DE 10 2007 025 263 A1 are described.
  • a technical and organizational challenge in many cases is that the contaminated cleaning items are not distributed evenly. Due in particular to group dynamics, timetables, or other circumstances beyond the control of the commercial kitchen, peak loads often occur, but so do times when little or no cleaning items are required. This poses a significant challenge for staff planning and the design of the cleaning equipment.
  • the system and personnel planning must generally be designed so that staff can cope with peak loads, which, however, may lead to underutilization of staff outside of peak loads. Therefore, staff planning and the design of the cleaning equipment must in many cases be oversized.
  • a dishwasher in the form of a commercial utensil or dishwashing machine designed as a programmable automatic machine, which is configured as a hood-type 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 selectively automatically loading the treatment chamber with items to be washed and/or for preferably selectively automatically unloading items to be washed from the treatment chamber.
  • KR 10 1 327 580 B1 Describes an automation system for dishwashers in which food trays and containers (soup bowls, rice bowls, side plates, lids, etc.) are separated by sprockets from a food tray guide carrier installed in the main body. The containers are guided through a drop hole of the food tray guide carrier for transfer to the first and second transfer conveyors installed below. Precision washing of the upper and lower parts of containers is performed automatically by incorporating a washing section into the middle section, and contaminated water is reused by further installing a filter circulator.
