Abstract

To avoid harming the waste water system by discharging over-hot wateR, a thermostat is fitted to the machine to measure the temp. of the cleaning soln. When the thermostat trips, at (a) opens a magnetic valve to supply cold water to a steam condenser, and (b) when the machine is pumping to waste, opens a second magnetic valve to mix cold water with the water being pumped away. Applies partic. to washing- and rinsing-machines used in hospitals and laboratories, which disinfect as well as cleaning, and whose cleaning soln. is usde very hot (e.g., 85 degrees C).

Description

Steuerungsartordnung für Wasch- oder Spülinaschinen Control type regulation for washing machines or dishwashers

Die Erfindung bezieht sich auf ein Steuerungsariordnung für Wasch- oder Spülmaschinen, insbesondere fär Wasch oder Spülmaschinen, welche in Krankenhäusern, Labors u. dgl. verwerdet werden.The invention relates to a control arrangement for washing or dishwashers, especially for washing machines or dishwashers used in hospitals, Laboratories and the like.

Bei den vorgenannten Was oh- oder Spülmasohinen wird das lfasch-oder Spülgut während des Programmablaufs sehr hohen Temperaturen ausgesetzt. So ist es z.I3. bei Maschinen mit einem Desinfektionsprogramm erforderlich, daß die TemperaLur der Lauge mindestens 850 C erreicht und über ojn bestimmten Zeitbereich auf-das zu behandelnde Gut einwirkt.In the case of the afore-mentioned was-oh or dish-washing machine, the lfasch-or Wash ware exposed to very high temperatures while the program is running. That's the way it is z.I3. machines with a disinfection program require that the TemperaLur the lye reaches at least 850 C and over a certain period of time on-that to be treated acts.

Dadurch kommt es zu einer starken Schwadenbildung und zu einer starken Wärmebelastung des Abwassersystems. Um diese störenden Einflüsse zu beseitigen, wird der im Behandlungsraum entstehende Wasserdampf durch einen Kondensator geführt und das Abwasser wird durch die Zuführung von Frischwasser abgekühlt.This leads to a strong plume formation and a strong one Heat load on the sewage system. To eliminate these disruptive influences, the water vapor generated in the treatment room is passed through a condenser and the wastewater is cooled by the addition of fresh water.

Die Aufgabe der Erfindung ist es, eine Steueranordnung zu schaffen, durch welche die vorbeschriebenen Mannahmen in einfacher Weise und ohne großen Aufwand bei einer Wasch- oder Spülmaschiiie durchgeführt werden und wobei die bestehende Stcuerschaltullg nur geringfügige Änderungen erfährt.The object of the invention is to create a control arrangement by means of which the above-described measures can be carried out in a simple manner and with little effort be carried out in a washing or dishwashing machine and the existing Control switch only undergoes minor changes.

Die Lösung dieser Aufgabe wird durch die Anwendung der im Hauptanspruch angeführten Merkmale gelöst.This problem is solved by applying the main claim cited features solved.

Ein Ausführiingsbeispiel der Erfindung wird anhand eines auszugsweise und schematisch dargestellten Stromlaufplanes erläutert.An exemplary embodiment of the invention is based on an extract and schematically illustrated circuit diagram explained.

Ein Thermostatschalter 1, der beispielsweise auf 500 C eingestellt ist, liegt in Reihe mit einem Relais 2. Weiterhin sind dem Thermostatsehalter 1 ein Kontakt 3 des Heizungsschützes der Maschine und ein Magnetventil 4 für die Kondensationseinrichtung nachgesehaltet.A thermostat switch 1, which is set to 500 C, for example is in series with a relay 2. Furthermore, the thermostat holder 1 a contact 3 of the heating contactor of the machine and a solenoid valve 4 for the condensation device followed up.

Die Laugenpumpe 5 der Maschine wird von dem Programmkontakt 6 gesteuert. Dem Programmkontakt 6 sind weiterhin ein Kontakt 2' des Relais 2 und das Magnetventil 7 für die Kaltwasserzufuhr zur Laugenabkühlung nachgeschaltet.The drain pump 5 of the machine is controlled by the program contact 6. The program contact 6 is also a contact 2 'of the relay 2 and the solenoid valve 7 downstream for the cold water supply to cool down the lye.

.Die Funktion der Schaltung ist wie folgt: Der Thermostatschalter 1 kann beispielsweise bei einer Laugentemperatur 500 C ansprechen.The function of the circuit is as follows: The thermostat switch 1 can respond, for example, at a caustic temperature of 500 C.

Dadurch zieht das Relais2anund über den bereits geschlossenen Kontakt 3 des Heizuiigsschützes kann das Magnetventil 4 für die Kondensationseinrichtung geöffnet werden.This pulls in the relay 2 and over the already closed contact 3 of the Heizuiigsschützes can the solenoid valve 4 for the condensation device be opened.

Im Abpumpschritt des ablaufenden Programms wird der Programmkontakt 6 geschlossen und die Laugenpumpe 5arbeitet Über den Kontakt 21 des Relais 2 wird das Magnetventil 7 geöffnet, so daß der abfließenden Lauge Kaltwasser zur Abkühlung zugeführt wird. Diese Kaltwasserzufuhr wird aber nur solange bewirkt wie der Thermostatschalter eingeschaltet ist.In the pumping step of the running program, the program contact 6 is closed and the drain pump 5 works via contact 21 of relay 2 the solenoid valve 7 opened, so that the draining liquor cold water for cooling is fed. This cold water supply is only effected as long as the thermostat switch is switched on.
