Abstract

The aim of the invention is to reduce the length of the rinsing cycle in a dish-washer and also the noise which is generated by the impact of the water therein without altering the performance of said dish-washer. Said inventive rinsing method for the dish-washer comprises at least two spraying devices, dividing a significant period of time (5) of the length of the rinsing programme (4) into a plurality of different lengths of sub-units of time (3). Practically every sub-unit of time (3) is made of at least two time-slots (1a, 1b, 2). During a first time-slot (2), the rinsing fluid passes through all of the spraying devices and during a second time-slot (1a, 1b), the liquid only passes through the lower or the higher spraying devices. The inventive dish-washer machine comprises at least two spraying devices which enables the utilisation of the above-mentioned rinsing method.

Description

Spülverfahren für Geschirrspülmaschinen und Geschirrspülmaschinen Washing process for dishwashers and dishwashers
Die Erfindung richtet sich auf ein Spülverfahren für Geschirrspülmaschinen mit mindes- tens zwei Sprüheinrichtungen sowie Geschirrspülmaschinen mit mindestens zwei Sprüheinrichtungen in denen das Spülverfahren zur Anwendung vorgesehen ist.The invention relates to a washing method for dishwashers with at least two spray devices and dishwashers with at least two spray devices in which the washing method is intended for use.
Geschirrspülmaschinen mit Wechselbetrieb der Sprühebenen sind seit langem bekannt, zum Beispiel aus der DE 24 28 901. Bei handelsüblichen Haushaltsgeschirrspülmaschi- nen werden die Sprüheinrichtungen gleichzeitig mit der von einer Umwälzpumpe geförderten Flüssigkeit beschickt. Dieses sogenannte Zweikorb- bzw. Mehrkorbspülen hat einerseits den Vorteil, dass die durch den Wasserstrahl auf das Spülgut einwirkende Kraft relativ hoch ist und somit das Ablösen der Speisereste relativ schnell vonstatten geht. Als nachteilig hat sich allerdings beim Zweikorb- bzw. Mehrkorbspülen ein hoher Wasser- und Energieverbrauch sowie die damit verbundene hohe Geräuschentwicklung erwiesen. Neben dem Zweikorb- bzw. Mehrkorbspülen ist ferner das sogenannte Wechselkorbspülen bekannt, bei dem im abwechselnden Betrieb die jeweiligen Sprühebenen gezielt angesteuert werden. Zwar ist der niedrige Wasser- und Energieverbrauch und die damit verbundene geringe Geräuschentwicklung vorteilhaft, jedoch ist die geringe mechanische Wirkung des Wasserstrahls durch die lediglich abwechselnden Sprühvorgänge auf das Spülgut nachteilig und führen zu einer Verlängerung der Spülprogrammlaufzeit.Dishwashers with alternating operation of the spray levels have long been known, for example from DE 24 28 901. In commercial household dishwashers, the spraying devices are simultaneously fed with the liquid conveyed by a circulating pump. This so-called two-basket or multi-basket rinsing has the advantage on the one hand that the force acting on the items to be washed by the water jet is relatively high, and thus the detachment of the food residues takes place relatively quickly. However, high water and energy consumption and the associated high level of noise have proven to be disadvantageous in two-basket or multi-basket rinsing. In addition to dual-basket or multi-basket rinsing, so-called interchangeable basket rinsing is also known, in which the respective spray levels are specifically controlled in alternating operation. Although the low water and energy consumption and the associated low noise development are advantageous, the low mechanical effect of the water jet due to the alternating spraying processes on the items to be washed is disadvantageous and lead to an extension of the washing program runtime.
Aufgabe der vorliegenden Erfindung ist es daher, unter Beibehaltung der Spülleistung, sowohl die Spülprogrammlaufzeit einer Geschirrspülmaschine als auch die Geräuschent- Wicklung, die durch das aufprallende Wasser verursacht wird, zu reduzieren.The object of the present invention is therefore, while maintaining the washing performance, to reduce both the washing program running time of a dishwasher and the noise development caused by the impacting water.
Diese Aufgabe wird durch das erfindungsgemäße Spülverfahren mit den Merkmalen gemäß Anspruch 1 bzw. mit den erfindungsgemäßen Geschirrspülmaschinen gemäß Anspruch 5 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Beim erfindungsgemäßen Spülverfahren für Geschirrspülmaschinen mit mindestens zwei Sprüheinrichtungen wird eine wesentliche Zeitspanne der Spülprogrammlaufzeit in eine Vielzahl von Unterzeiteinheiten aufgeteilt, wobei im wesentlichen jede Unterzeiteinheit aus mindestens zwei Zeitabschnitten besteht und wobei während eines ersten Zeitabschnitts alle Sprüheinrichtungen von Spülflüssigkeit durchströmt werden und während eines zwei- ten Zeitabschnitts lediglich die Unterste oder die Oberste der Sprüheinrichtungen von Spülflüssigkeit durchströmt wird.This object is achieved by the washing method according to the invention with the features according to claim 1 or with the dishwashing machines according to the invention according to claim 5. Advantageous developments of the invention are characterized in the subclaims. In the washing method according to the invention for dishwashers with at least two spray devices, a substantial period of the washing program runtime is divided into a plurality of sub-time units, with essentially each sub-time unit consisting of at least two time sections and with washing liquid flowing through all the spray devices during a first time section and during a second Only the lowermost or the uppermost of the spraying devices is flowed through by washing liquid.
Bei einer bevorzugten Variante des erfindungsgemäßen Spülverfahrens sind in einer Unterzeiteinheit zwei Zeitabschnitte vorgesehen, in denen sich die Beaufschlagung durch die obere und die untere Sprüheinrichtung abwechseln.In a preferred variant of the flushing method according to the invention, two time periods are provided in a sub-time unit, in which the action by the upper and the lower spraying device alternate.
Vorteilhafterweise grenzt jeweils der erste Zeitabschnitt unmittelbar an den zweiten Zeitabschnitt an. Gemäß der jeweiligen Spülprogrammauswahl kann die Länge der jeweiligen Zeitabschnitte bestimmt werden. Zweckmäßigerweise ist bei der Wahl eines Spülpro- gramms bei dem besonders stark verschmutztes Spülgut im unteren Geschirrkorb angeordnet ist, der zweite Zeitabschnitt, bei dem lediglich die Unterste der Sprüheinrichtungen von Spülflüssigkeit durchströmt wird länger, als bei einem Spülprogramm bei dem das im Oberkorb befindliche Spülgut nur unwesentlich weniger verschmutzt ist, als das im Unterkorb befindliche Spülgut, so dass der erste und zweite Zeitabschnitt in diesem Fall im we- sentlichen gleich lang sind.The first time period advantageously borders directly on the second time period. The length of the respective time segments can be determined in accordance with the respective wash program selection. When selecting a wash program in which particularly heavily soiled washware is arranged in the lower crockery basket, the second time period in which only the bottom of the spraying devices is flushed with washing liquid is expediently longer than in the case of a wash program in which the washware located in the upper basket only is insignificantly less dirty than the items to be washed in the lower basket, so that the first and second time periods are essentially of the same length in this case.
Bei Anwendung des erfindungsgemäßen Spülverfahrens wird im zweiten Zeitabschnitt, während lediglich die Unterste oder Oberste der Sprüheinrichtungen von Spülflüssigkeit durchströmt wird, das im untersten oder obersten Geschirrkorb befindliche Spülgut mit einer höheren mechanischen Wasserkraft beaufschlagt, so dass die Reinigungsleistung für das im unteren bzw. oberen Geschirrkorb befindliche Spülgut wesentlich gesteigert wird. Durch die Verkürzung der Umwälzzeiten aufgrund der von der Spülflotten ausgeübten höheren Mechanik, wird die Spülprogrammlaufzeit reduziert und durch das zumindest zeitweise Einkorbspülen, wobei lediglich die untere Sprüheinrichtung betätigt wird, wird vorteilhafterweise die Geräuschentwicklung reduziert.When using the washing method according to the invention, in the second period, while only the lowermost or uppermost of the spraying devices are flushed with washing liquid, the items in the lowest or uppermost crockery basket are subjected to a higher mechanical hydropower, so that the cleaning performance for those in the lower or upper crockery basket existing wash ware is significantly increased. By shortening the circulation times due to the higher mechanics exercised by the washing liquors, the running time of the washing program is reduced and by at least temporarily washing the basket, with only the lower spraying device being actuated, the noise development is advantageously reduced.
Mit dem erfindungsgemäßen Spülverfahren als auch mit den erfindungsgemäßen Geschirrspülmaschinen mit mindestens zwei Sprüheinrichtungen, in der erfindungsgemäß das erfindungsgemäße Spülverfahren zur Anwendung vorgesehen ist, ist es gelungen, unter Beibehaltung der Spülleistung, sowohl die Spülprogrammlaufzeit der Geschirrspülmaschine als auch die Geräuschentwicklung, die durch das aufprallende Wasser verursacht wird, zu reduzieren.With the dishwashing method according to the invention and also with the dishwashing machines according to the invention with at least two spray devices, in the according to the invention the rinsing method according to the invention is intended for use, it has been possible to reduce the rinsing program runtime of the dishwasher as well as the noise that is caused by the impacting water while maintaining the rinsing performance.
Zwei Ausführungsvarianten des erfindungsgemäßen Spülverfahrens werden anhand von Zeitdiagrammen näher erläutert. Es zeigen:Two variants of the flushing method according to the invention are explained in more detail with the aid of time diagrams. Show it:
Fig. 1 eine Ausführungsvariante des erfindungsgemäßen Spülverfahrens mit lediglich zwei Zeitabschnitten, so dass ein Unterkorbspülen und ein Zweikorbspülen vorgenommen wird undFig. 1 shows a variant of the flushing method according to the invention with only two time periods, so that a lower basket rinsing and a two-basket rinsing is carried out and
Fig. 2. eine Ausführungsvariante des erfindungsgemäßen Spülverfahrens während eines vollständigen Spülprogramms mit mehreren Zeitabschnitten, so dass ein Unterkorbspülen, Zweikorb- und Ober- korbspülen vorgenommen wird.2 shows an embodiment variant of the flushing method according to the invention during a complete flushing program with several time periods, so that a lower basket flush, two basket flush and upper basket flush are carried out.
In dem Diagramm der Figur 1 ist auf der X-Achse die Spülprogrammlaufzeit t und auf der Y-Achse die zu messende Geräuschentwicklung dB während des Spülprogramms aufgetragen. Die Spülprogrammlaufzeit 4 ist unterteilt in eine wesentliche Zeitspanne 5 die ih- rerseits in eine Vielzahl von Unterzeiteinheiten 3 aufgeteilt wird. Die Längen der Unterzeiteinheiten 3 richtet sich nach der jeweiligen Spülprogrammeinstellung, welche wiederum vom Verschmutzungsgrad bzw. der Temperaturwahl abhängt. Die Unterzeiteinheit 3 ist unterteilt in einen ersten Zeitabschnitt 2 und einen zweiten Zeitabschnitt 1 a, die unmittelbar aneinander grenzen. Nach Beenden des Zeitabschnitts 2 fängt erneut ein Zeitab- schnitt 1a an, an dessen Ende sich erneut ein Zeitabschnitt 2 anschließt. Die Länge des ersten bzw. zweiten Zeitabschnitts 2, 1a ist abhängig von der Spülprogrammlaufzeit.In the diagram in FIG. 1, the washing program running time t is plotted on the X axis and the noise development dB to be measured during the washing program is plotted on the Y axis. The washing program runtime 4 is divided into an essential time period 5, which in turn is divided into a plurality of sub-time units 3. The lengths of the sub-time units 3 depend on the respective wash program setting, which in turn depends on the degree of soiling or the choice of temperature. The sub-time unit 3 is divided into a first time period 2 and a second time period 1 a, which directly adjoin one another. After the end of the time period 2, a time period 1 a begins again, at the end of which another time period 2 follows. The length of the first or second time period 2, 1a depends on the duration of the washing program.
Die durch die Sprüheinrichtungen verursachte Geräuschentwicklung verändert sich in den jeweiligen Zeitabschnitten 2, 1a, wobei im Zeitabschnitt 2 Ober- und Unterkorb gleichzeitig mit Spülflüssigkeit beaufschlagt werden und somit ein höheres Geräuschniveau B vorliegt, während im Zeitabschnitt 1a lediglich der Unterkorb über die Sprüheinrichtung mit Spülflüssigkeit beaufschlagt wird und daher der Geräuschpegel lediglich das Niveau A erreicht. Erfindungsgemäß können während der Spülprogrammlaufzeit 4 mehrere Zeitspannen 5 beginnen und enden, abhängig von dem jeweiligen Spülprogramm. Durch eine solche Programmwahl ist es daher möglich, den unterschiedlichen Spülprogrammen durch die Auswahl der Spülzeitdauern unterschiedliche Charakteristiken zuzuordnen. Vorteilhafter- weise wird die von der Umwälzpumpe geförderte Spülflotte über eine nicht näher erläuterte Wasserweiche, die von dem jeweiligen Spülprogramm gesteuert wird, in die jeweils aktivierten Rohrabschnitte geleitet, um entsprechend des dargestellten Rhythmus die Sprüheinrichtungen bzw. Sprüheinrichtung zu durchströmen.The noise generated by the spray devices changes in the respective time sections 2, 1a, with washing liquid being applied to the upper and lower basket simultaneously in the time section 2 and thus a higher noise level B being present, while in the time section 1a only washing liquid is applied to the lower basket via the spray device and therefore the noise level only reaches level A. According to the invention, a plurality of time periods 5 can begin and end during the washing program runtime 4, depending on the respective washing program. By selecting such a program, it is therefore possible to assign different characteristics to the different washing programs by selecting the washing times. Advantageously, the rinsing liquor conveyed by the circulating pump is passed into the respectively activated pipe sections via a water separator, which is not explained in greater detail, and which is controlled by the respective rinsing program, in order to flow through the spraying devices or spraying device in accordance with the rhythm shown.
In dem Diagramm gemäß Figur 2 ist ein vollständiger Spülprogrammablauf mit zwei Varianten gezeigt, wobei die jeweiligen Spülprogrammabschnitte mittels römischer Ziffern gekennzeichnet sind. Nach dem Start eines Spülprogramms wird in der Phase I ein Vorspülen des Spülguts vorgenommen und erfindungsgemäß die Unterzeiteinheit 3 in Zeitabschnitten 1a und 1b aufgeteilt, so dass ein sogenanntes Wechselkorbspülen zwischen Unter- und Oberkorb ausgeführt wird. In dieser Spülprogrammphase I werden zwei Geräuschniveaus A und A* erreicht, wobei A das Niveau der Geräuschentwicklung des Un- terkorbspülens und A* das Geräuschniveau des Oberkorbspülens widerspiegelt. Nach der Spülprogrammphase I folgt die Spülprogrammphase II in der die Spülflotte aufgeheizt wird. Im Anschluß daran folgt die Spülprogrammphase III in der alle Sprüheinrichtungen mit Spülflüssigkeit beaufschlagt werden und somit das Geräuschniveau B erreicht wird. Als Alternative zu der Spülprogrammphase II wird beispielsweise für andere Länder, wie insbesondere für die USA, die Spülprogrammphase Na zum Aufheizen der Spülflüssigkeit verwendet, gefolgt von der Spülprogrammphase IV in der zum Reinigen zwischen der Zweikorbspülung und der Einkorbspülung unterschieden wird, so dass die Zeitabschnitte 2 und 1a aufeinander folgen. Im Anschluß an die jeweiligen Varianten III bzw. IV schließt sich die Spülphase des Zwischenspülens V an, in der die Zeitabschnitte 1a und 1b abwechselnd vorgenommen werden und schließlich nach Zugabe des Klarspülers die Spülprogrammphase VI beginnt, in der das Spülgut ebenfalls gemäß den Rhythmen der Zeitabschnitte 1a und 1b klargespült werden.A complete washing program sequence with two variants is shown in the diagram according to FIG. 2, the respective washing program sections being identified by means of Roman numerals. After the start of a washing program, the items to be washed are pre-washed in phase I and, according to the invention, the sub-time unit 3 is divided into time sections 1a and 1b, so that a so-called interchangeable basket rinsing is carried out between the lower and upper basket. In this wash program phase I, two noise levels A and A * are reached, with A reflecting the level of noise generated in the lower basket and A * reflecting the level in the upper basket. After the wash program phase I follows the wash program phase II in which the washing liquor is heated up. This is followed by the rinsing program phase III, in which all the spray devices are acted on with rinsing liquid and thus the noise level B is reached. As an alternative to the wash program phase II, the wash program phase Na is used, for example, for other countries, such as in particular for the USA, to heat up the washing liquid, followed by the washing program phase IV, in which a distinction is made between two-basket washing and single-basket washing for cleaning, so that the time segments 2 and 1a follow each other. Following the respective variants III and IV, the rinsing phase of intermediate rinsing V follows, in which periods 1a and 1b are carried out alternately, and finally, after the rinse aid has been added, rinsing program phase VI begins, in which the items to be washed likewise follow the rhythm of the periods 1a and 1b are rinsed clear.
Mit dem erfindungsgemäßen Spülverfahren als auch mit den erfindungsgemäßen Geschirrspülmaschinen mit mindestens zwei Sprüheinrichtungen, in der erfindungsgemäß das erfindungsgemäße Spülverfahren zur Anwendung vorgesehen ist, ist es gelungen, unter Beibehaltung der Spülleistung, sowohl die Spülprogrammlaufzeit der Geschirrspülmaschine als auch die Geräuschentwicklung, die durch das aufprallende Wasser verursacht wird, zu reduzieren. With the flushing method according to the invention and also with the dishwashing machines according to the invention with at least two spray devices in which the flushing method according to the invention is intended for use, it has been possible to while maintaining the washing performance, to reduce both the washing time of the dishwasher and the noise caused by the impacting water.
