Patentanspruch:Claim: Programmsteuereinrichtung für eine Geschirrspülmaschine, bei deren Einschalten die Programmsteuereinrichtung in einer dem vorher gewählten Arbeitsprogramm entsprechenden Reihenfolge und Zeitdauer das öffnen und Schließen der Wasserzufuhr in einen Arbeitsbehälter, das Ein- und Ausschalten der Arbeitseinrichtung der Maschine sowie einer Pumpe zum Abpumpen des Wassers aus dem Arbeitsbehälter der Maschine steuert, dadurch gekennzeichnet, daß in die Programmsteuereinrichtung als erste Arbeitsstufe vor dem Wassereinlauf bei Beginn des Arbeitsprogramms das kurzzeitige Einschalten der Wasserpumpe zum Abpumpen eines im Arbeitsbehälter bzw. dessen Ablauf vorhandenen Restwassers eingebaut istProgram control device for a dishwasher, the program control device when it is switched on the opening and closing of the water supply in a sequence and duration corresponding to the previously selected work program in a working container, switching on and off the working equipment of the machine as well as a pump for pumping out the water from the working tank of the machine controls, thereby characterized in that in the program control device as the first working stage before the water inlet at the start of the work program briefly switching on the water pump for pumping out any residual water present in the working tank or its drain is installed Die Erfindung betrifft eine Programmsteuereinrichlung für eine Geschirrspülmaschine, bei deren Einschalten die Programmsteuereinrichtung in einer dem vorher gewählten Arbeitsprogramm entsprechenden Reihenfolge und Zeitdauer das öffnen und Schließen der Wasserzufuhr in einen Arbeitsbehälter, das Ein- und Ausschalten der Arbeitseinrichtungen der Maschine sowie einer Pumpe zum Abpumpen des Wassers aus dem Arbeitsbehälter der Maschine steuert.The invention relates to a program control device for a dishwasher, when switched on, the program control device in one of the previous The selected work program opens and closes the corresponding sequence and duration Water supply into a work tank, the switching on and off of the working equipment of the machine as well as controls a pump for pumping out the water from the working tank of the machine. Es isl bei Programmsteuereinrichtungen der genannten Art bekannt, daß am Endp des Arbeitsprogramms nach dem Ausschalten der das Wasser aus dem Arbeitsbehälter fördernden Pumpe das in der Pumpe sowie in einem die Pumpe mit einem Ablaufanschluß verbindenden Abiaufschlauch befindliche Restwasser in den Arbeitsbehälter der Maschine zurückfließt. Pumpen mit Ventilen und Kolbenpumpen, die ein Zurückfließen des Wassers verhindern könnten, sind bei Geschirrspülmaschinen nicht anwendbar, das Speisereste u. dgl. die Ventile bzw. die Kanäle der Kolbenpumpen zusetzen würden. Das sich im Arbeitsbehälter sammelnde Restwasser wird noch vermehrt durch vom gereinigten Geschirr und von den Einrichtungen im Arbeitsbehälter abtropfendes Wasser, das nach --igerer Standzeit einen unangenehmen Geruch v- rsacht.It is known in program control devices of the type mentioned that at the end p of the work program after switching off the pump conveying the water from the working tank, the residual water in the pump and in a drain hose connecting the pump to a drainage connection flows back into the working tank of the machine. Pumps with valves and piston pumps, which could prevent the water from flowing back, cannot be used in dishwashers, which would clog the valves or the channels of the piston pumps, as food residues and the like would clog. The residual water that collects in the work container is increased by water dripping from the cleaned dishes and from the equipment in the work container, which gives off an unpleasant odor after a long period of standing. ίο Beim Beladen der Geschirrspülmaschine können außerdem Suppen-, Soßen- und andere Speisereste in das Restwasser gelangen.ίο When loading the dishwasher you can In addition, soup, sauce and other food residues get into the residual water. Die angeführten Nachteile werden gemäß der Erfindung dadurch vermieden, daß in die Programmsteuereinrichtung als erste Arbeitsstufe vor dem Wassereinlauf bei Beginn des Arbeitsprogramms das kurzzeitige Einschalten der Wasserpumpe zum Abpumpen eines im Arbeitsbehälter bzw. dessen Ablauf vorhandenen Restwassers eingebaut istThe stated disadvantages are avoided according to the invention in that in the program control device as the first work stage before the water inlet at the beginning of the work program, the short-term Switching on the water pump to pump out any residual water in the working tank or its drain is built in Hierdurch wird erreicht, daß vor Beginn des eigentlichen Spülprogramms wenigstens ein Teil des im Arbeitsbehälter vorhandenen Wasserrestes abgepumpt wird, so das verschmutzte Wasserreste nur in verringerter Menge in den neuen Spülprozeß übernommen werden. Dies ist insofern vorteilhaft, als dadurch die Schmutztragefähigkeit des Spülwassers nicht unnötig stark eingeschränkt wird.This ensures that before the start of the actual washing program, at least part of the in the working container Existing water residue is pumped out, so the polluted water residue is only reduced Amount can be transferred to the new rinsing process. This is advantageous in that it enables the The dirt-carrying capacity of the rinsing water is not unnecessarily restricted. Beim Beginn eines Arbeitsprogramms der Geschirrspülmaschine wird mit dem Startimpuls immer erst die Pumpe zum Abpumpen eines vorhandenen Wasserrestes eingeschaltet. Die Einschaltdauer der Pumpe kann dabei beispielsweise 15 oder 30 Sekunden betragen. Diese Zeit genügt in der Regel, um einen Teil des vorhandenen Wasserrestes sicher aus dem Wasserbehälter bzw. dessen Ablauf schlauch zu entfernen. Nach diesem ersten Arbeitsgang »Pumpen« läuft dann das jeweils vorher gewählte Arbeitsprogramm ab.At the beginning of a working program of the dishwasher, the start pulse always starts with the Pump switched on to pump out any residual water. The duty cycle of the pump can be for example 15 or 30 seconds. This time is usually sufficient to cover part of the existing one Safely remove water residues from the water tank or its drainage hose. After this The first work step »Pumping« then runs the previously selected work program.
