Description

       

      Geschirrwaschmaschine       Für Hotels und grössere Küchenbetriebe werden  Geschirrwaschmaschinen mit kontinuierlicher Bewe  gung eines Geschirr tragenden Transportbandes ver  wandt, wobei das Geschirr eine Waschzone und eine  darauffolgende     Nachspülzone    durchläuft. Während  die Waschlauge in der Waschzone grösstenteils weiter  verwendet wird, muss das Spülwasser immer wieder  erneuert werden. Daher ist mit dem Spülvorgang ein  grosser Wasserverbrauch und wegen der Erwärmung  auch ein entsprechend hoher Stromverbrauch ver  bunden. Dazu kommen gegebenenfalls noch Zusätze  in Gestalt von     Glanztrocknungsmitteln    und derglei  chen.

   Dieser Nachteil tritt vor allem dann in Erschei  nung, wenn die Maschine nicht voll ausgenutzt ist,  weil nur kleinere Posten an     Geschirr    durchlaufen.  



  Die Erfindung vermeidet die genannten Nachteile  dadurch, dass die Ein- und Ausschaltung des Spül  wassers selbsttätig mittels einer     Photozellensteuerung     erfolgt.  



  Zweckmässig wird am Beginn der     Nachspülzone     ein Lichtgeber angeordnet, der einen Lichtstrahl quer  über das Transportband auf eine Photozelle     wirft.     



  Die Anordnung kann so getroffen werden, dass  die Abschaltung des Spülwassers mit einer gewissen  einstellbaren Verzögerung erfolgt.  



  In der Zeichnung ist ein Ausführungsbeispiel der  Erfindung dargestellt. Es zeigen:       Fig.    1 eine schaubildliche Darstellung der Anord  nung,       Fig.2    ein Blockschaltbild der     Photozellensteue-          rung.     



  Das Transportband 1 ist als endloses Band ausge  bildet und bewegt sich kontinuierlich mit dem darauf  befindlichen Geschirr 2 nach vorn, wobei letzteres    eine Waschzone 3 und danach eine     Spülzone    4  durchläuft. Das Spülwasser     fliesst    von der Leitung 5  durch das Regulierventil 6 in die Leitung 7 und  spritzt bei     geöffnetem    Ventil aus den Spritzdüsen 8  auf das durchlaufende Geschirr.  



  Am     Beginn    der     Spülzone    4 ist ein Lichtgeber 9  angeordnet, der ständig einen Lichtstrahl 10 quer  über das Transportband 1 auf die gegenüberliegende  Photozelle 11     wirft.    Sobald der Lichtstrahl 10 durch  Geschirr 2 unterbrochen wird, gibt die Photozelle 11  einen Impuls auf einen Verstärker 12, der seinerseits  das Regulierventil 6     öffnet.    Der     Verstärker    12 wird  von der Stromquelle 13 gespeist und liefert die Span  nung für die Lichtquelle des Lichtgebers 9. Die Ab  schaltung des Ventils 6 erfolgt selbsttätig mit einer  gewissen Verzögerung, sodass die     einzelnen    Ge  schirrstücke mit Sicherheit über eine gewisse Strecke  vom Spülwasser erfasst werden.



      Dish washing machine For hotels and larger kitchen operations, dish washing machines are used with continuous movement of a conveyor belt carrying dishes, with the dishes passing through a washing zone and a subsequent rinsing zone. While most of the detergent in the washing zone continues to be used, the rinsing water has to be renewed again and again. Therefore, a large amount of water is consumed with the flushing process and, because of the heating, also a correspondingly high consumption of electricity. In addition, there may be additives in the form of gloss drying agents and the like.

   This disadvantage is particularly evident when the machine is not being used to the full because only small items of dishes are passing through.



  The invention avoids the disadvantages mentioned in that the flushing water is switched on and off automatically by means of a photocell control.



  A light generator is expediently arranged at the beginning of the final-rinse zone and throws a light beam across the conveyor belt onto a photocell.



  The arrangement can be made so that the flushing water is switched off with a certain adjustable delay.



  An exemplary embodiment of the invention is shown in the drawing. They show: FIG. 1 a diagrammatic representation of the arrangement, FIG. 2 a block diagram of the photocell control.



  The conveyor belt 1 is formed out as an endless belt and moves forward continuously with the crockery 2 thereon, the latter going through a washing zone 3 and then a washing zone 4. The rinsing water flows from the line 5 through the regulating valve 6 into the line 7 and, when the valve is open, sprays from the spray nozzles 8 onto the dishes passing through.



  At the beginning of the rinsing zone 4, a light generator 9 is arranged, which constantly throws a light beam 10 across the conveyor belt 1 onto the photocell 11 opposite. As soon as the light beam 10 is interrupted by dishes 2, the photocell 11 sends a pulse to an amplifier 12, which in turn opens the regulating valve 6. The amplifier 12 is fed by the power source 13 and supplies the voltage for the light source of the light transmitter 9. The valve 6 is switched off automatically with a certain delay, so that the individual pieces of crockery are reliably detected by the wash water over a certain distance.
