Definitions

  • the invention is directed to a method for cleaning dishes in Dishwashers, in which particulate detergent from one a detergent container arranged outside the dishwasher Conveying line fed, sucked into this and pneumatically directly into the Washing area of the dishwasher receiving washware is conveyed Furthermore, the invention is directed to a dishwasher Clearing zone or cycle and / or one or more washing zones or cycles in which a detergent container with the wash ware pneumatic conveying line connecting the receiving washing zone particulate detergent directly into the free space of the washing zone Dishwasher opens.
  • cutlery and crockery and tableware are also included other items usually cleaned in commercial dishwashers Understood.
  • the aim should therefore be a direct dosage from the sales container into the Dishwasher.
  • the different requirements for the Dosage quantities and dosing accuracy to be observed While for commercial washer-extractors dosing quantities from 4 to 6 kg / min are typical, with continuous washing lines about 0.1 to 1.5 kg / min and in commercial dishwashers, which are also of the type of Rinsing lines work, only 10 to 20 g / min metered. Adhering to such low doses creates additional difficulties.
  • a metering device for powdered detergent the first the powder from one or more storage containers by means of discharge screws into a dosing container and only then pneumatically into the washing machine promotes (DE-A-39 07 361). A direct dosage from the sales container into the Machine is not made here either.
  • a highly concentrated detergent solution indicates more than 0.5% by weight active cleaning substance. While liquid detergents are already manufactured by the manufacturer must be available in such a highly concentrated form powdered detergent only in a stock container to such a prepared highly concentrated solution and kept ready for the rinsing process become. This additional step when using particulate Detergent involves an undesirable effort.
  • EP-A-0611843 describes a method for cleaning dishes Dishwashers known in which particulate detergent from a preferably arranged outside the dishwasher Detergent container supplied to a conveyor line, preferably in this is sucked, and pneumatically directly into a receiving the washware Washing zone of the dishwasher is promoted. Furthermore, from this Patent application for a dishwasher with a clearing zone or cycle and / or one or more wash zones or cycles, in which one one preferably arranged outside the dishwasher Detergent container with a washing zone that receives the wash ware connecting pneumatic delivery line for particulate detergent opens directly into the free space in the washing zone of the dishwasher.
  • the invention is therefore based on the object in a generic Method and a generic dishwasher the particulate Use detergents even more efficiently.
  • the cleaning agent is applied directly to the wet wash ware will blow directed. This means that the detergent can be used immediately its undiminished cleaning power when entering the dishwasher unfold the desired position.
  • the invention is particularly advantageous in a method for mechanical Cleaning of tableware in a commercial dishwasher with a or more washing zones or cycles in which the Utensils first by spraying with water for a rough cleaning is subjected.
  • the tableware is then used for rough cleaning before the first actual washing zone or the first actual washing cycle or between two washing zones or cycles in the dishwasher sprayed pneumatically conveyed cleaning powder.
  • the highly concentrated cleaning solution is created particularly quickly when that particulate detergent is blown in the form of a powder mist, such as this provides the invention in an embodiment.
  • the cleaning powder in such an amount and on such Sprayed on that the dishes are almost completely powder-covered, like this the invention provides in a further embodiment.
  • the cleaning agent is preferably applied with a fan-shaped jet characteristic the dishes are inflated, which the invention also provides. So you get a very even distribution of the cleaning agent on the to be cleaned Surfaces.
  • Inflating the detergent onto the dishes can be done in different ways Way.
  • this occurs Particulate cleaning agents in the respective rinsing chamber at only one opening a delivery line and at the same time this opening in an in essential horizontal level, especially periodically, fan-shaped back and forth pivoted here, so that the blown product evenly on the Washware distributed.
  • the end of the delivery line can be pivoted, for example Hose be formed, as in an embodiment below is described in more detail.
  • the powder can also be applied to the wash ware via several nozzles inflate and in this way a uniform distribution of the Detergent can be achieved.
  • the invention also provides that in addition to blowing a fine water mist is sprayed from the cleaning agent.
  • the water mist knocks down the powder and spreads it evenly on the Surface of the wash ware.
  • the equipment necessary for the circulation of the returned cleaning powder can also be used to convey fresh cleaning powder be used.
  • the cleaning agent after a contact time of 5 to 100 seconds, preferably 8 to 25 seconds in one or more subsequent steps is rinsed off.
  • the dissolution rate and the cleaning behavior as well as the composition of common dishwashing detergents powders are sufficient for carrying out the method according to the invention, so that the invention is further characterized in that the Cleaning powder is a common dishwasher cleaner.
  • the powder can, for example, with sucked into a blower, passed through it and finally into the machine be blown.
  • a so-called injector can advantageously be used, which has a suction line is connected to a suction lance arranged in the powder container.
  • Both Injectors are compressed air through an annular gap within the Venturi housing fed.
  • Different versions of injectors, including those directly in the Powder packs to be injected fall as the mouthpiece of a suction lance serve are possible. It is possible that the powder with a compressed air operated injector sucked, passed through the injector and from the pressure side from the injector into the machine.
  • Air from the machine is important because the amount of air entered with the powder is relatively high.
  • An additional advantage is achieved with a conveyor system consisting of a compressed air powered suction lance, the compressed air via a upstream propellant nozzle is supplied.
  • the system works with very little Air volumes, allows a fine adjustment of the flow rate of the powder and is therefore particularly suitable for dosing in a dishwasher. It is therefore possible that the compressed air of the powder feed line through one of its inlet upstream propellant nozzle is supplied.
  • the on a so-called catch nozzle Directed driving nozzle causes local fluidization of the powder.
  • the fluidized Product is fed to the catch nozzle and into the machine via a line promoted.
  • the invention therefore further provides that the cleaning center before Suction with compressed air is locally fluidized.
  • the driving nozzle upstream of the inlet of the powder feed line enables the Reduce powder flow down to the smallest amount.
  • the Powder feed Foreign air fed into the delivery line With that you can on the one hand create portions. On the other hand, the delivery line is blown free, and product accumulation in the line can be prevented. Becomes a Blower used, the suction line can be directly behind or inside vent the suction lance via a solenoid valve.
  • the injector is intermittent, in particular in time periodically operated with pressurized working fluid.
  • the compressed air is e.g. B. generated by a small compressor with a connected pressure vessel. It a connecting line from a pressure source to the injector can be provided, which has a solenoid valve with a relatively large cross section. For a short time Opening the solenoid valve creates a short, powerful suction stroke. With this The method of shock relief can be easily portioned reach sucked powder.
  • the invention provides in Design therefore before that the cleaning agent continuously or periodically is blown in.
  • the powder from the powder container in particular directly from the sales container, so it is particularly favorable if the compressed air of the powder feed line via one of them Inlet upstream propellant nozzle is supplied.
  • This dosing process is further have already been explained in more detail above.
  • the powder is over a tubular elbow in the area of the spray register of the Dishwasher promoted. Penetration of steam (vapors) from the usually at relatively high temperatures, e.g. B. about 70 C, working Dishwasher is very effectively prevented if the manifold outlet is only during the dosing process is opened. This can be done with a spring-loaded flap be provided.
  • the invention further relates to a generic dishwasher.
  • a generic dishwasher is the one mentioned above Object achieved in that it is a commercial dishwasher acts and that the at least one opening of the pneumatic The delivery line is directed towards the wet wash ware.
