The claims 2 to 10 relate to particularly preferred embodiments of the dishwasher according to the invention according to claim 1, the claims 12 to 18 relate to particularly advantageous embodiments of the method according to claim 11.
Gemäß der Erfindung umfasst eine Geschirrspülmaschine einen Spülraum, wobei die Geschirrspülmaschine ferner eine Tür zum Öffnen und Schließen des Spülraumes umfasst. Der Nutzer kann die Tür der Geschirrspülmaschine öffnen, um Spülgut in den Spülraum zu stellen, wobei die Tür nach dem Füllen oder teilweisen Füllen des Spülraums wieder geschlossen werden kann, oder um gereinigtes Spülgut wieder zu entnehmen.According to the invention, a dishwasher comprises a washing compartment, wherein the dishwasher further comprises a door for opening and closing the washing compartment. The user can open the door of the dishwasher to put items to be washed in the washroom, the door after filling or partial filling of the washing compartment can be closed again, or to remove cleaned items again.
Gemäß der Erfindung umfasst die Geschirrspülmaschine einen Startschalter zum Starten eines Spülprogramms und einen Wahlschalter zur Auswahl eines ersten Betriebsmodus oder eines zweiten Betriebsmodus umfasst, bevorzugt beispielsweise in einer Bedieneinheit zusammengefasst. Die Geschirrspülmaschine gemäß der Erfindung umfasst ferner einen Sensor zum Erfassen eines Zeitpunkts tC, zu dem die Tür geschlossen wird, sowie einen Timer, der so ausgebildet ist, dass er einen Zeitraum ΔtC misst, der ab einem Zeitpunkt tC, zu dem die Tür geschlossen wird, vergangen ist. Ferner umfasst die erfindungsgemäße Geschirrspülmaschine eine Steuervorrichtung, die so ausgebildet ist, dass in dem Falle, dass über den Wahlschalter der erste Betriebsmodus gewählt ist und dass innerhalb eines vorbestimmten Zeitraums Δt1 nach einem Schließen der Tür der Startschalter nicht betätigt wird, automatisch ein Einweichprogramm der Geschirrspülmaschine gestartet wird.According to the invention, the dishwasher comprises a start switch for starting a wash program and a selector switch for selecting a first operating mode or a second operating mode, preferably combined, for example, in an operating unit. The dishwasher according to the invention further comprises a sensor for detecting a time t C , to which the door is closed, and a timer, which is designed so that it measures a period .DELTA.t C , from a time t C , to the Door is closed, has passed. Furthermore, the dishwasher according to the invention comprises a control device which is designed so that in the event that the first operating mode is selected via the selector switch and that within a predetermined period .DELTA.t 1 after closing the door of the start switch is not actuated automatically a soaking program Dishwasher is started.
Eine erfindungsgemäße Geschirrspülmaschine hat den Vorteil, dass der Nutzer zwischen einem ersten Betriebsmodus und einem zweiten Betriebsmodus wählen kann, wobei es sich bei dem zweiten Betriebsmodus beispielsweise um einen standardüblichen Betriebsmodus handelt, bei dem der Nutzer wunschgemäß verschiedene Spülprogramme wählt, die die Geschirrspülmaschine zur Verfügung hat, wobei der Nutzer manuell und zu jedem beliebigen Zeitpunkt das oder die entsprechenden Spülprogramme wählen kann und dann mittels des Startschalters das oder die Spülprogramme starten kann.A dishwasher according to the invention has the advantage that the user can choose between a first operating mode and a second operating mode, wherein the second operating mode is, for example, a standard operating mode in which the user desires to select different washing programs that the dishwasher has available in which the user can manually and at any time select the appropriate washing program (s) and then start the washing program (s) by means of the start switch.
Der Nutzer hat bei der erfindungsgemäßen Geschirrspülmaschine jedoch auch die Möglichkeit, grundsätzlich, das heißt nicht nur für einen bestimmten Vorgang oder ein gerade einzustellendes Spülprogramm, beispielsweise das nächstfolgende Spülprogramm, einen ersten Betriebsmodus zu wählen, der insbesondere über mehrere Spülvorgänge, mehrere Stunden oder Tage eingestellt bleibt. Zumindest bei diesem ersten Betriebsmodus wird durch einen Sensor und einen Timer die Zeit gemessen, die nach einem Schließen der Tür vergeht, wobei erfindungsgemäß bei Wahl des ersten Betriebsmodus ein Einweichprogramm der Geschirrspülmaschine automatisch gestartet wird, wenn eine vorbestimmte, bevorzugt auch einstellbare, Zeit Δt1 vergangen ist.In the dishwasher according to the invention, however, the user also has the option, basically, not only of selecting a particular process or a rinse program to be set, for example the next rinse program, to select a first operating mode which is set over several rinses, several hours or days remains. At least in this first mode of operation is measured by a sensor and a timer, the time elapses after closing the door, according to the invention when choosing the first mode of operation, a soaking program of the dishwasher is automatically started when a predetermined, preferably adjustable, time .DELTA.t. 1 has passed.
Wird durch den Nutzer Spülgut in den Spülraum der Geschirrspülmaschine gestellt, die Tür wieder geschlossen und direkt nachfolgend durch den Benutzer der Startschalter zum Starten eines Spülprogramms betätigt, beginnt die Geschirrspülmaschine das gewählte Spülprogramm. Startet der Nutzer jedoch nicht innerhalb des vorbestimmten Zeitraums Δt1 ein Spülprogramm, ist davon auszugehen, dass die Geschirrspülmaschine beispielsweise noch nicht vollständig mit Spülgut gefüllt ist oder der Nutzer aus einem anderen Grund das Spülprogramm noch nicht starten will.If the user places items to be washed in the dishwasher's dishwasher compartment, closes the door again and actuates the start switch for starting a wash program directly afterwards by the user, the dishwasher starts the selected wash program. However, if the user does not start a washing program within the predetermined time period Δt 1 , it can be assumed that the dishwasher is not yet ready, for example is completely filled with items to be washed or the user does not want to start the wash program for another reason yet.
Befindet sich nun die Geschirrspülmaschine in dem ursprünglich gewählten ersten Betriebsmodus, startet die Spülmaschine in diesem Falle automatisch ein Einweichprogramm, ohne dass der Nutzer dieses Einweichprogramm manuell auswählt und/oder startet oder einen anderen Bedienschritt ausführt, außer dem Schließen der Tür der Geschirrspülmaschine.In this case, if the dishwasher is in the originally selected first operating mode, the dishwasher will automatically start a soaking program without the user manually selecting and / or starting this soaking program or performing any other operation than closing the door of the dishwasher.
Die erfindungsgemäße Geschirrspülmaschine hat daher den Vorteil, dass sie, wenn sie sich im ersten Betriebsmodus befindet, automatisch in Abhängigkeit vom Benutzerverhalten ein zusätzliches Einweichprogramm startet oder aber eben nicht startet, nämlich wenn der Nutzer innerhalb eines vorbestimmten Zeitraums Δt1 bereits das eigentliche Spülprogramm oder die eigentlichen Spülprogramme startet.The dishwashing machine according to the invention therefore has the advantage that, when it is in the first operating mode, it automatically starts an additional soaking program depending on the user behavior or does not start, namely if the user already has the actual washing program within a predetermined period Δt 1 actual wash programs starts.
Daher wird sichergestellt, dass ohne zusätzliche Aktivitäten des Nutzers automatisch ein Einweichprogramm gestartet wird, allerdings nur, wenn dieses Einweichprogramm auch notwendig ist, nämlich insbesondere in den Fällen, in denen in den Spülraum eingeladenes Spülgut noch länger dort verbleibt, ohne dass das eigentliche Spülprogramm der Geschirrspülmaschine gestartet wird, so dass verhindert wird, dass die Verschmutzungen an dem Spülgut antrocknen oder so dass bereits angetrocknete Verschmutzung eingeweicht werden, um nach dem Start des eigentlichen Spülprogrammes ein besseres Spülergebnis zu erzielen. Auf der anderen Seite wird ein Einweichprogramm nicht zwangsweise vorgeschaltet, wenn innerhalb einer vorbestimmten Zeitspanne, des vorbestimmten Zeitraums Δt1, das Spülprogramm gestartet wird, so dass die Geschirrspülmaschine in diesen Fällen besonders energieeffizient arbeiten kann.Therefore, it is ensured that without additional activities of the user automatically a soaking program is started, but only if this soaking program is also necessary, namely in particular in cases in which loaded in the washing compartment remains there even longer, without the actual washing program of Dishwasher is started, so that prevents the dirt on the items to dry or so that already dried dirt are soaked in order to achieve a better dishwashing result after the start of the actual wash program. On the other hand, a soaking program is not necessarily preceded when, within a predetermined period of time, the predetermined period .DELTA.t 1 , the wash program is started, so that the dishwasher can work in these cases particularly energy efficient.
Bevorzugt umfasst die erfindungsgemäße Geschirrspülmaschine ein Waschsystem zur Abgabe eines fluiden Mediums während des Durchführens des Einweichprogramms. Dieses Waschsystem kann ein Waschsystem sein, das auch für eines der normalen Spülprogramme verwendet wird, es ist jedoch auch möglich, ein davon getrenntes Waschsystem vorzusehen, das ausschließlich für das Einweichprogramm vorgesehen ist.The dishwasher according to the invention preferably comprises a washing system for dispensing a fluid medium during the execution of the soaking program. This washing system may be a washing system which is also used for one of the normal washing programs, but it is also possible to provide a separate washing system intended exclusively for the soaking program.
Bevorzugt umfasst die erfindungsgemäße Geschirrspülmaschine einen Tank zur Aufnahme eines fluiden Mediums, das zur Durchführung des Einweichprogramms verwendet wird, und eine Pumpenvorrichtung, mittels derer das fluide Medium aus dem Tank dem mindestens einen Waschsystem zugeführt wird.Preferably, the dishwasher according to the invention comprises a tank for receiving a fluid medium, which is used to carry out the soaking program, and a pump device, by means of which the fluid medium from the tank is supplied to the at least one washing system.
Bei einer besonders bevorzugten Ausführungsform umfasst die erfindungsgemäße Geschirrspülmaschine ferner einer Vorratsbehälter für eine Zusammensetzung, insbesondere eine Zusammensetzung in fluider Form, und eine Dosierpumpenvorrichtung, die so ausgebildet ist, dass die Zusammensetzung einem fluiden Medium, das wenigstens einem Waschsystem zuführbar ist, zumindest zeitweise beigemengt werden kann.In a particularly preferred embodiment, the dishwasher according to the invention further comprises a reservoir for a composition, in particular a composition in fluid form, and a Dosierpumpenvorrichtung, which is designed so that the composition of a fluid medium, which is at least one washing system supplied, at least temporarily added can.
Dies hat den Vorteil, dass dem fluiden Medium, das während des Einweichprogramms verwendet wird, zumindest teilweise ein Zusatz, die Zusammensetzung, beigemengt wird, was die Einweichwirkung oder andere, reinigende Wirkungen oder vorbereitende Wirkungen für die Reinigung unterstützt.This has the advantage that, at least in part, an additive, the composition, is added to the fluid medium used during the soaking program, which aids soaking or other cleansing or preparatory effects for cleaning.
Bei einer besonders bevorzugten Ausführungsform umfasst die Geschirrspülmaschine mindestens ein Waschsystem und mindestens ein Nachspülsystem, wobei bevorzugt das mindestens eine Waschsystem so ausgebildet ist, dass es während des Durchführens des Einweichprogramms verwendet wird, wobei dem mindestens einen Waschsystem das fluide Medium aus einem Tank der Spülmaschine zugeführt werden kann. Bei einer besonders bevorzugten Ausführungsform ist auch mindestens ein Nachspülsystem vorgesehen, das insbesondere während eines Nachspülprogramms verwendet wird und über das ebenfalls ein fluides Medium abgegeben werden kann, wobei diesem mindestens einen Nachspülsystem bevorzugt Frischwasser zugeführt werden kann, gegebenenfalls unter zumindest zeitweiser Beimischungen eines Klarspülmittels.In a particularly preferred embodiment, the dishwasher comprises at least one washing system and at least one post-rinse system, wherein preferably the at least one washing system is adapted to be used during the execution of the soaking program, wherein the at least one washing system supplies the fluid medium from a tank to the dishwasher can be. In a particularly preferred embodiment, at least one Nachspülsystem is also provided, which is used in particular during a Nachspülprogramms and on the also a fluid medium can be dispensed, wherein this at least one Nachspülsystem preferably fresh water can be supplied, optionally with at least temporary admixtures of a rinse aid.
Die Wasch- oder Spülsysteme in einer solchen, besonders bevorzugten Geschirrspülmaschine, sind daher in zwei Arten getrennt, wobei ein Waschsystem im Wesentlichen der Durchführung des Einweichprogramms und des oder der Spülprogramme dient, während ein Nachspülsystem im Wesentlichen während eines Nachspülprogramms verwendet wird.The washing or rinsing systems in such a particularly preferred dishwashing machine are therefore separate in two ways, with a washing system essentially serving to execute the soaking program and wash program (s) while a post-rinse system is used substantially during a rinse off program.
Bevorzugt ist die Steuervorrichtung einer erfindungsgemäßen Geschirrspülmaschine so ausgebildet, dass der vorbestimmte Zeitraum Δt1 in einen Bereich von 1 Sekunde bis 15 Minuten, bevorzugt in einem Zeitraum von 1 Sekunde bis 5 Minuten, insbesondere bevorzugt in einem Zeitraum von 1 Sekunde bis 2 Minuten, liegt. Diese Zeiträume haben, je nach Anwendungsgebiet der Geschirrspülmaschine, insbesondere der gewerblichen Geschirrspülmaschine, den Vorteil, dass der Zeitraum Δt1 so gewählt ist, dass ein Einweichprogramm zum einen nur dann gestartet wird, wenn es erforderlich ist, zum anderen der Zeitraum Δt1 so gewählt wird, dass dieser Zeitraum nicht so lange ist, dass Verschmutzungen an dem Spülgut antrocken, bevor ein Spülprogramm manuell gestartet wird.Preferably, the control device of a dishwasher according to the invention is designed so that the predetermined period .DELTA.t 1 in a range of 1 second to 15 minutes, preferably in a period of 1 second to 5 minutes, more preferably in a period of 1 second to 2 minutes , These periods have, depending on the field of application of the dishwasher, in particular the commercial dishwasher, the advantage that the period .DELTA.t 1 is selected so that a soaking program is only started for a, if it is necessary, on the other hand, the period .DELTA.t 1 selected so is that this period is not so long that dirt on the items to be washed before a wash program is started manually.
Bei einer besonders bevorzugten Ausführungsform der Geschirrspülmaschine ist der Sensor so ausgelegt, dass er zusätzlich einen Zeitpunkt tO erfassen kann, zu dem die Tür der Geschirrspülmaschine geöffnet wird, wobei der Timer bevorzugt so ausgebildet ist, dass er einen Zeitraum ΔtO misst, der seit einem Zeitpunkt tO, zu dem die Tür geöffnet ist, bis zu einem Zeitpunkt tC, zu dem die Tür wieder geschlossen worden ist, vergangen ist.In a particularly preferred embodiment of the dishwasher, the sensor is designed such that it can additionally detect a point in time t 0 at which the door of the dishwasher is opened, wherein the timer is preferably designed such that it measures a period .DELTA.t O since a time t o , to which the door is open, until a time t C , to which the door has been closed again, has passed.
Bevorzugt ist dabei die Steuervorrichtung so ausgebildet, dass das Einweichprogramm der Geschirrspülmaschine nur dann gestartet wird, wenn der zuletzt gemessene Zeitraum ΔtO zwischen dem Zeitpunkt tO des letzten Öffnens und dem Zeitpunkt tC des letzten Schließens der Tür länger als ein vorbestimmter Zeitraum Δt2 ist.Preferably, the control device is designed so that the soaking program of the dishwasher is only started when the last measured period .DELTA.t O between the time t O of the last opening and the time t C of the last closing of the door longer than a predetermined period .DELTA.t 2 is.
Eine solche Ausführungsform hat den Vorteil, dass in den Fällen, in denen der Nutzer beispielsweise nur kurz in den Spülraum sieht, um beispielsweise zu prüfen, wie hoch der Füllstand der Geschirrspülmaschine mit Spülgut bereits ist, ohne neues Spülgut einzuräumen, nicht automatisch ein Einweichprogramm gestartet wird.Such an embodiment has the advantage that in cases where the user sees, for example, only briefly in the washing compartment, for example, to check how high the level of the dishwasher with dishes is already without giving new items to be washed, not automatically started a soaking program becomes.
Der Zeitraum Δt2 wird daher bevorzugt so gewählt, dass er einen maximalen Zeitraum umfasst, in dem typischerweise kein neues Spülgut in den Spülraum eingesetzt wird, bevorzugt einem Zeitraum von 0 bis 120 Sekunden, insbesondere bevorzugt in einem Zeitraum von 0 bis 30 Sekunden, insbesondere bevorzugt in einem Zeitraum von 0 bis 10 Sekunden. Dadurch wird vermieden, dass ein Einweichprogramm gestartet wird, obwohl dies eigentlich nicht erforderlich ist, nachdem kein neues Spülgut in den Spülraum eingesetzt worden ist.The period .DELTA.t 2 is therefore preferably selected so that it comprises a maximum period in which typically no new items to be washed is inserted into the washing chamber, preferably a period from 0 to 120 seconds, particularly preferably in a period of 0 to 30 seconds, in particular preferably in a period of 0 to 10 seconds. This avoids that a soaking program is started, although this is actually not required after no new items to be washed has been inserted into the washing compartment.
Bei einer besonders bevorzugten Ausführungsform umfasst eine Zusammensetzung, die in einem Vorratsbehälter der erfindungsgemäßen Geschirrspülmaschine vorgesehen ist und die mittels einer Dosierpumpenvorrichtung einem Waschsystem zuführbar ist, mindestens ein nichtionisches Tensid, mindestens ein anionisches Tensid, mindestens einen Emulgator, mindestens ein Stellmittel, und mindestens ein Enzym, wobei die Zusammensetzung frei von Phosphaten, Bleichmitteln und alkalisch wirkenden Substanzen ist.In a particularly preferred embodiment, a composition which is provided in a storage container of the dishwasher according to the invention and which can be fed to a washing system by means of a metering pump device comprises at least one nonionic surfactant, at least one anionic surfactant, at least one emulsifier, at least one setting agent, and at least one enzyme , wherein the composition is free of phosphates, bleaching agents and alkaline substances.
Diese besondere Zusammensetzung erhöht deutlich den gewünschten Einweicheffekt beziehungsweise den Effekt zur Vorbereitung auf ein später folgendes Spülprogramm, so dass in den Fällen, in denen diese Zusammensetzung zumindest zeitweise dem fluiden Medium während des Einweichprogramms zugeführt wird, das nachfolgende Spülergebnis deutlich verbessert wird.This particular composition significantly increases the desired soaking effect or the effect of preparing for a subsequent rinse program, so that in cases where this composition is at least temporarily supplied to the fluid medium during the soaking program, the subsequent rinse result is significantly improved.
