  • the devices and methods of the invention can be used to clean vessels, in particular to clean bottles.
  • the invention can be used in particular in the field of dishwashing technology, in particular in the field of commercial dishwashing technology.
  • the invention can be used in particular in canteen kitchens in which items to be cleaned, for example trays, crockery and cutlery, have to be cleaned in large quantities.
  • the invention can be used to clean bottles, for example bottles for table water in restaurants, or other bottle-like objects such as wine carafes, lemonade jugs or similar items to be cleaned with at least one cavity.
  • bottles for example bottles for table water in restaurants, or other bottle-like objects such as wine carafes, lemonade jugs or similar items to be cleaned with at least one cavity.
  • other areas of use are also conceivable in principle.
  • cleaning devices also referred to as cleaning devices, which can clean and/or disinfect items to be cleaned.
  • the design of these cleaning devices depends greatly on the various boundary conditions, such as the type of items to be cleaned, the level of dirt, the throughput or similar conditions.
  • cleaning devices which, for example, in DE 10 2004 056 052 A1 or in DE 10 2007 025 263 A1 are described.
  • This document describes a bottle rinsing basket device for a commercial dishwasher with two separate rinsing systems, which includes a basket support and a rinsing basket for accommodating bottles to be cleaned.
  • the basket support includes a docking device with at least two feed channels that are separate from one another, and the washing basket includes a distribution system with a distribution flange that can be connected to the docking device of the basket support.
  • a dispensing tube for dispensing liquid onto bottles to be cleaned is provided, which is connected to a common distribution channel of a distribution system, liquids from each of the two rinsing systems being able to be supplied to this dispensing tube via the common distribution channel.
  • the DE 77 02 174 U1 describes an insert basket for a dishwasher with nozzle mandrels for attaching hollow items to be washed, such as bottles, glasses or the like, and with a pipe system to which the nozzle mandrels are connected and which is provided with connecting pipe sockets for supplying washing water, characterized in that immediately next to or a further nozzle pipe section extends with a wall spacing in each nozzle mandrel, and that the insert basket has a further separate pipe system with a separate connecting pipe socket for supplying a fluid for the special treatment of the interior of the hollow items to be washed, to which the nozzle pipe sections are connected.
  • the U.S. 3,590,863 A describes a laboratory glassware washing machine having an improved coupler which includes an interchangeable turret and has rails adapted to receive a roll-up trolley carrying a variety of supports including a spindle cradle and a pipette holder.
  • the U.S. 5,010,660A describes an apparatus for washing and vacuum drying long-necked laboratory flasks.
  • the apparatus includes a cabinet containing a washing and drying compartment and a pump and a rotating spray arm.
  • a special frame that can be rolled in and out of the chamber includes a central manifold and a plurality of manifold arms that extend radially from the manifold.
  • Upright spindle tubes extend from the distributor arms for receiving the inverted pistons so that the tubes pass through the narrow necks of the pistons and the open ends of the tubes lie within the piston bodies.
  • a diaphragm coupling allows water to be pumped to the manifold, which is directed to the spindle tubes during the wash and rinse cycles.
  • the tubes spray the water directly inside the piston bodies for thorough washing and rinsing.
  • a vacuum line extending from the manifold carries a seat which engages a gasket to couple the manifold to a vacuum fan when the rack is moved into the cabinet.
  • the blower pulls a vacuum on the spindle tubes through the manifold to draw moist air from the pistons and replace it with drier air from the cabinet.
  • the vacuum drying system recirculates and heats the air and mixes it with dry outside air to improve flask drying.
  • the final-rinse system is dimensioned significantly smaller than the washing system, since the washing system usually works in circulation mode with considerable amounts of liquid and must not be blocked by dirt particles, whereas the final-rinse system usually works with significantly smaller volumes of liquid and not in circulation mode is used.
  • typical volumes of final-rinse tanks can be less than 3 liters, which are applied to the items to be cleaned during the final-rinse step, for example, within less than 20 seconds.
  • valve systems must be easy to open, since in particular the pressure of the final-rinse fluid can only be designed to be comparatively low due to the small amounts of liquid.
  • valves that are easy to open, in particular check valves in many cases result in susceptibility to contamination, which can accumulate in the valve and impair the tightness of the valve. In this way, contamination of the final-rinse fluid with washing fluid can take place.
  • valve systems are complex and expensive in practice and increase the structural volume and the manufacturing costs of the rinsing baskets.
  • a further disadvantage of such systems is that they are difficult to clean in practice, since backwashing, for example, is generally not possible due to the principle involved.
  • the systems described can only be dismantled by a specialist and not by appropriate operating personnel.
  • the terms “have”, “have”, “comprise” or “include” or any grammatical deviations thereof are used in a non-exclusive manner. Accordingly, these terms can refer both to situations in which, apart from the features introduced by these terms, no further features are present, or to situations in which one or more further features are present.
  • the expression “A has B”, “A has B”, “A comprises B” or “A includes B” can both refer to the situation in which, apart from B, no other element in A is present (ie to a situation in which A consists exclusively of B), as well as to the situation in which, in addition to B, there are one or more other elements in A, e.g. element C, elements C and D or even further elements .

  • the dimensions of the at least one final-rinse nozzle opening can be made significantly smaller than the at least one washing nozzle opening. Accordingly, the fact that the final-rinse fluid is generally available in significantly smaller amounts than the washing fluid, and the fact that the washing fluid is generally applied in circulation mode and the final-rinse fluid is used only once, can be taken into account .
  • a spray jet suitable for rinsing can be generated, for example, even with small amounts of rinsing fluid with a comparatively low throughput.
