Definitions

  • the invention relates to a dishwasher according to the preamble of claim 1.
  • a dishwasher according to the preamble of claim 1.
  • the wash ware is replaced by a or several rinsing zones and then through one or more Rinse aid zones transported and cleaned while doing so rinsed clear.
  • the position of the items to be washed changes on automatic programs not inside the machine.
  • the cleaning is done with Soapy water from a tank and then the Fresh water rinse in the same position.
  • the rinsing solution is pumped over and over Nozzle systems sprayed over the dishes.
  • the rinse result is in addition to the parameters
  • the proportion of detergent, the rinsing mechanism and the exposure time are heavily dependent of the amount of dirt dissolved in the soapy water, which is caused by the soiled wash ware is introduced.
  • the Washware is a liquid film in which, depending on the Alkaline pollution, a certain amount of dirt is present is. This amount of dirt in the liquid film with the items to be washed in continuous machines in the next Rinsing zone delayed or complicates rinsing Programmers and continuous machines.
  • the soapy water are by the inflowing fresh water, which at Continuous systems cascaded through the machine or, in the case of automatic programs, directly into the soapy water tank is directed, regenerated.
  • the need for regeneration water for the rinse tanks is u. a. depending on the amount of dirt introduced.
  • the contamination of the inside of the tank is also dependent from the amount of dirt brought into the machine or from the amount of loosened dirt present in the soapy water. At a slight soiling of the lye is manual Cleaning effort to clean the inner surfaces essential less.
  • Dishwashers of the type mentioned are in the DE-OS 1703612 and described in DE-PS 1965828.
  • a centrifugal separator For Concentration of the rinse water of the collecting container is there a centrifugal separator is provided, which flushes the water in a highly concentrated dirty water that drains can be fed, and in a correspondingly cleaner Separates clean water or clear water. This will go up in pressed the rinsing zone where it is in the collection container is initiated. With the cleaning spraying process of Dishwasher has this clean water obtained nothing to do, however. For the cleaning process, the entire contents of the collecting container used.
  • the invention has for its object a Dishwasher according to the preamble of claim 1 To be designed so that the cleaning process is more effective and cleaning agents can be saved.
  • the water from the Collecting container at least one rinsing zone a centrifugal separator fed the rinse water into a concentrated waste water for drainage into a drain presses, the clean water obtained immediately the Spray device for spraying the passed Washware, preferably in the pre-wash zone, is supplied.
  • a valve can be opened and closed that can be opened via the Control of the dishwasher can be controlled.
  • Continuous flow systems are the derivation for the concentrated Dirty water from the centrifugal separator so laid that the overflowing regeneration water increases in the tank remains and is specifically discharged as wastewater Automatic programmer, that is, with fixed wash ware proceeded in a similar manner.
  • FIG. 1 shows a side view of a commercial continuous dishwasher, where the - not shown - Dishes on a conveyor belt or the like through the entire machine is transported through.
  • the dishes passes through several separate rinsing zones, namely the Pre-wash zone 2, the main wash zone 3, the regeneration wash zone 4 and the fresh water rinsing zone 5.
  • Heat recovery device 6 and a drying zone 7.
  • the start of the run is 1, the end of the Run designated 8, the direction of movement is with 25 designated.
  • a water spray device 9 In the pre-rinse zone 2 is a water spray device 9 and a further regeneration water spray device 10 is provided, in the main washing zone 3 there is a water spray device 11 provided in the regeneration zone 4 a Regeneration water spray device 12, in the Fresh water rinsing zone 5 a fresh water spray device 13.
  • the individual spray devices are double formed, with an upper partial spray device from above and a lower partial spray device from below onto the water is sprayed between them, namely some fresh water, some more or less strong dirty regeneration water or rinse water.
  • Known facilities are not detailed here shown.
  • An important object of the invention is the pre-rinse zone 2 the rinse water collecting container 17 and the following ones Facilities.
  • the bottom of the collecting container 17 is over a feed line 21a and a circulation pump 21 with a Centrifugal separator 20 connected, as such is previously known and for example in DE-PS 1965828 and DE-OS 1703612 is described. That laterally in the after tapered conical centrifugal separator below 20 flushing water of the collecting container 17 introduced under pressure there is pushed into down and up pressed clear water separated. The latter is directly over a corresponding supply line for the water spray device 9 fed to the pre-rinse zone 2.
  • the dirty water is over the Line 24a pushed up, to the top of the Collecting container 17, from where it has an inlet or Drain overflow 24 into an adjacent drain 23 can.
  • On the opposite side of the inlet 24 Outflow 23 is the overflow 14 of the collecting container 17th arranged the same the maximum liquid level Are defined.
  • Centrifugal separator 20 largely purified water immediately for pre-washing the wash items in the pre-wash zone 2, after which it is via a second spray device 10, which from Regeneration water of the regeneration collecting container 19 is fed, can enter the next treatment zone.
  • Figure 2 shows in cross section the collecting container 17, the Overflow 14 with a pre-chamber 27 provided therein Inlet 24 for the dirty water and the drain 23.
  • FIG. 3 shows an exemplary embodiment for a pre-rinse zone 2 or a simple dishwasher with no pass where the wash ware is always in the same place and the individual functions performed sequentially become.
  • a collecting chamber 28 for the dirty water below the conical narrowing of the centrifugal separator 20 shown a magnetic valve 29 is shown below, which has access to drain 23 only at certain times releases. The control of this valve can be done by the normal control program of the dishwasher be performed.
  • Figure 4 shows in principle the same representation as Figure 3, only with an additional line 9a to additional or alternative spray devices 9a, which are behind the common circulation pump 21, but in front of the centrifugal separator 20 is provided to make the dirtier Rinse water from below to act directly on the wash ware leave, while from above the cleaner, from the centrifugal separator clear water escaping upwards over the Water spray device 9 is sprayed onto the wash ware.
