Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Geschirrspülmaschine gemäß dem
Oberbegriff des Anspruches 1 und eine Geschirrspülmaschine gemäß dem Oberbegriff
des Anspruches 8.The invention relates to a method for operating a dishwasher according to the
Preamble of
Bei Geschirrspülmaschinen kommt es immer wieder vor, dass die Sprühöffnungen der Sprüheinrichtung sich im Laufe der Zeit durch Ablagerungen, insbesondere Kalkablagerungen, teilweise oder ganz zusetzen, so dass nicht mehr genügend oder gar keine Spülflüssigkeit mehr durch die Sprühöffnungen hindurchtreten kann. Dies führt zu schlechten Reinigungsergebnissen. Derartige Verstopfungen der Sprühöffnungen sind für den Benutzer der Geschirrspülmaschine kaum oder gar nicht erkennbar, so dass auch keine Abhilfe vorgenommen werden kann.In dishwashers, it often happens that the spray openings of the Spray device over time due to deposits, especially limescale, partially or completely clogged so that there is no longer enough or no rinsing liquid at all more can pass through the spray openings. This leads to bad ones Cleaning results. Such blockages of the spray openings are for the user the dishwasher hardly or not at all, so that none Remedy can be made.
Der Erfindung liegt die Aufgabe zugrunde, für den Benutzer einer Geschirrspülmaschine Verstopfungen der Sprühöffnungen leicht erkennbar zu machen.The invention has for its object for the user of a dishwasher Make blockages of the spray openings easily recognizable.
Die Lösung der gestellten Aufgabe gelingt bei einem Verfahren zum Betrieb einer Geschirrspülmaschine nach der Erfindung dadurch, dass auch bei geöffneter Spülraumtür die Pumpe eingeschaltet und Spülflüssigkeit zugeführt werden kann, wobei jedoch gleichzeitig die Durchflussmenge der Spülflüssigkeit durch die Sprühöffnungen soweit reduziert wird, dass kein Abspritzen von Spülflüssigkeit durch die offene Türöffnung nach außen in die freie Umgebung erfolgt. Der Benutzer einer Geschirrspülmaschine kann somit bei geöffneter Spülraumtür die Sprüheinrichtung beobachten und erkennen, ob an allen Sprühöffnungen Spülflüssigkeit austritt, bzw. feststellen ob an verschiedenen Sprühöffnungen eine unterschiedliche Menge an Spülflüssigkeit austritt. Dies ist ein Zeichen dafür, dass zumindest eine teilweise Verstopfung der jeweiligen Sprühöffnungen vorliegt. Der Benutzer kann dann gezielt die betreffenden Sprühöffnungen reinigen, so dass wieder ein einwandfreier Durchfluss der Spülflüssigkeit durch die Sprühöffnungen gewährleistet ist. Mit der Erfindung ist es gelungen, für den Benutzer einer Geschirrspülmaschine Verstopfungen der Sprühöffnungen leicht erkennbar zu machen. The problem is solved in a method for operating a dishwasher according to the invention in that even when the washroom door is open the pump can be switched on and rinsing liquid can be supplied, however at the same time the flow rate of the flushing liquid through the spray openings it is reduced that there is no splashing of washing liquid through the open door opening after outside into the free environment. The user of a dishwasher can thus When the washroom door is open, observe the spraying device and see whether it is on rinsing liquid escapes from all spray openings or determine whether at different Spray openings a different amount of flushing liquid emerges. This is a sign that at least a partial blockage of the respective spray openings is present. The user can then specifically clean the spray openings in question, so that again a perfect flow of the rinsing liquid through the spray openings is guaranteed. The invention has succeeded for the user of a dishwasher Make blockages of the spray openings easily recognizable.
Eine einfache Möglichkeit zum Reduzieren der Durchflussmenge besteht darin, dass in Abhängigkeit von der Offenstellung der Spülraumtür eine Absenkung der Pumpendrehzahl erfolgt, so dass deren Förderleistung soweit reduziert wird, dass kein Abspritzen von Spülflüssigkeit in die freie Umgebung eintritt. In Abhängigkeit von der Offenstellung der Spülraumtür kann auf den elektrischen Steuerkreis der Pumpe eingewirkt werden, um so deren Förderleistung zu vermindern. Dabei kann zunächst auf eine bestimmte Mindestförderleistung zurückgeschaltet werden. Es besteht dann die Möglichkeit mittels eines im Steuerkreis der Pumpe angeordneten, von Hand verstellbaren Steuergliedes, beispielweise eines Potentiometers, eine für die Überprüfung geeignete Förderleistung der Pumpe einzuregulieren.An easy way to reduce the flow is that in Depending on the open position of the wash cabinet door, a reduction in the pump speed takes place so that their delivery rate is reduced to such an extent that no spraying of Flushing liquid enters the free environment. Depending on the open position of the The wash chamber door can be operated on the electrical control circuit of the pump, and so on reduce their output. This can initially be based on a certain minimum output be switched back. It is then possible to use an im Control circuit of the pump arranged, manually adjustable control element, for example of a potentiometer, a pump output suitable for checking einzuregulieren.
Eine Reduzierung der Durchflussmenge kann auch dadurch erreicht werden, dass in Abhängigkeit von der Offenstellung der Spülraumtür mindestens ein in der Zuleitung von der Pumpe zu der Sprüheinheit angeordnetes, die Durchflussmenge reduzierendes Drosselorgan aktiviert wird. In diesem Falle kann die Pumpe mit normaler Leistung betrieben werden und das Drosselorgan sorgt für die Minderung der Durchflussmenge. Dabei kann es wiederum von Vorteil sein, dass die Durchflussmenge des Drosselorganes regulierbar ist.A reduction in the flow rate can also be achieved by depending on at least one in the supply line from the open position of the wash cabinet door Pump arranged to the spray unit and reducing the flow rate is activated. In this case the pump can be operated at normal power and the throttle body ensures that the flow rate is reduced. It can it in turn be advantageous that the flow rate of the throttle body is adjustable is.
Als Drosselorgan kann ein Druckminderungsventil zum Einsatz kommen. Es besteht auch die Möglichkeit als Drosselorgan ein Blendenelement vorzusehen, dessen Blendenöffnung mittels eines in Abhängigkeit von der Offenstellung der Spülraumtür angesteuerten Antriebsgliedes in Richtung verminderter Durchlassfähigkeit verstellt wird oder ein im Zweitaktverfahren gesteuertes Ventil zu verwenden, wobei die Zweitaktsteuerung in Abhängigkeit von der Offenstellung der Spülraumtür in Gang gesetzt wird.A pressure reducing valve can be used as a throttling device. It also exists the possibility of providing a diaphragm element as a throttle element, its diaphragm opening by means of one controlled as a function of the open position of the wash cabinet door Drive member is adjusted in the direction of reduced permeability or an in Two-stroke controlled valve to use, the two-stroke control depending from the open position of the washroom door.
Die eingangs genannte Aufgabe wird bei einer nach dem vorbeschriebenen Verfahren betreibbaren Geschirrspülmaschine dadurch gelöst, dass ein Steuerelement vorgesehen ist, durch das bei geöffneter Spülraumtür direkt oder indirekt sowohl die Pumpe einschaltbar als auch die Zufuhr von Spülflüssigkeit freigebbar ist, dass ferner ein die Offenstellung der Spülraumtür erfassender Sensor vorhanden ist, durch den eine Drosselung der Durchflussmenge von Spülflüssigkeit durch die Sprühöffnungen bei geöffneter Spülraumtür ausgelöst ist. Mittels des Steuerelementes kann ein Prüfprogramm aktiviert werden, durch das auch bei geöffneter Spülraumtür die Pumpe eingeschaltet und die Zufuhr von Spülflüssigkeit freigegeben wird. Gleichzeitig wird durch den die Offenstellung der Spülraumtür erfassenden Sensor die Durchflussmenge an den Sprühöffnungen reduziert. Damit ist ohne die Gefahr des Austretens von Spülflüssigkeit aus dem Spülraum eine Überprüfung der Durchlässigkeit der Sprühöffnungen möglich.The task mentioned at the outset is based on the procedure described above operable dishwasher solved in that a control element is provided can be switched on either directly or indirectly by the pump when the wash cabinet door is open and the supply of rinsing liquid can be released, furthermore the open position the sink door sensor is present, through which a throttling the flow rate of flushing liquid through the spray openings when the wash cabinet door is open is triggered. A test program can be activated by means of the control element, by means of which the pump is switched on and the supply also when the wash cabinet door is open of rinsing liquid is released. At the same time, the open position of the Sensor detecting the wash cabinet door reduces the flow rate at the spray openings. This means that there is no risk of flushing liquid escaping from the wash cabinet Checking the permeability of the spray openings possible.
Der Sensor kann in Abhängigkeit vom Betätigen des das Prüfprogramm aktivierenden Steuerelementes eingeschaltet werden.The sensor can be activated depending on the activation of the test program Control are turned on.
Zweckmäßig ist es, wenn durch ein Steuersignal des Sensors der elektrische Steuerkreis der Pumpe im Sinne einer Verminderung der Förderleistung der Pumpe beeinflusst ist. Über ihren elektrischen Steuerkreis kann die Pumpe in ihrer Drehzahl und damit in ihrer Förderleistung soweit heruntergefahren werden, dass kein Abspritzen von Spülflüssigkeit aus dem Spülraum heraus nach außen erfolgt.It is expedient if the electrical control circuit is triggered by a control signal from the sensor the pump is affected in the sense of a reduction in the delivery capacity of the pump. Via its electrical control circuit, the speed and thus the pump can Conveying capacity must be shut down so that no flushing liquid is sprayed off from the wash cabinet to the outside.
Eine weitere Möglichkeit zum Reduzieren der Durchflussmenge besteht darin, dass in der Zuleitung von der Pumpe zu der Sprüheinrichtung ein in seiner Durchflussmenge durch ein Steuersignal des Sensors regulierbares Drosselorgan angeordnet ist.Another way to reduce the flow rate is that in the The flow from the pump to the spray device a control signal of the sensor adjustable throttle body is arranged.
Als Drosselorgan kann vorteilhafterweise ein Druckminderungsventil oder ein Blendenelement vorgesehen sein, dessen Blendenöffnung durch ein Steuersignal des Sensors im Sinne einer Verminderung der Durchflussmenge verstellbar ist. Werden solche Drosselorgane verwendet, dann kann die Pumpe auch während der Durchführung einer Überprüfung der Durchlässigkeit der Sprühöffnungen mit ihrer normalen Leistung betrieben werden.A pressure reducing valve or an orifice element can advantageously be used as the throttle element be provided, the aperture opening by a control signal from the sensor in Is adjustable to reduce the flow rate. Such throttling organs used, then the pump can also be run while performing a check the permeability of the spray openings operated at their normal performance become.
