Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Betreiben einer Waschmaschine, insbesondere einer Trommelwaschmaschine gemäß dem Oberbegriff des Anspruches 1, wobei eine nach diesem Verfahren arbeitende Waschmaschine sowohl für den Einsatz im Haushalt, als auch für gewerbliche Zwecke geeignet ist und in bestimmten Baumodifikationen zur Anwendung kommen kann.The invention relates to a method for operating a washing machine, in particular a drum washing machine according to the preamble of claim 1, a washing machine operating according to this method being suitable for use in the household as well as for commercial purposes and being used in certain construction modifications can.
Bisher sind anhand der Patentliteratur, durch Firmenschriften und sehr vielfältigem Prospektmaterial sowie bereits auf dem Markt befindlichen Konsumgütern nur Trommelwaschmaschinen mit einer Wasch- und Schleudertrommel bekannt.
Bei diesen Maschinen erfolgt der Wasch-, Spül- und Schleudervorgang nur in einer Wasch- und Schleudertrommel, wobei in etwa 4,5 kg Trockenwäsche in einem Waschzyklus mit einem relativ günstigen Wasser-, Energie- und Waschmittelverbrauch sowie einem annehmbaren Reinigungseffekt bearbeitet werden kann.So far, only drum washing machines with a washing and centrifugal drum are known based on the patent literature, company documents and a wide range of brochure material as well as consumer goods already on the market.
In these machines, the washing, rinsing and spinning process takes place only in one washing and spinning drum, whereby about 4.5 kg of dry laundry can be processed in a washing cycle with a relatively low consumption of water, energy and detergent as well as an acceptable cleaning effect.
Bei diesen allgemein bekannten Wasch- und Schleudermaschinen wird die verwendete Flotte jeweils nach Abschluß eines Waschganges (Vor- oder Hauptwäsche) bzw. nach jedem einzelnen Spülgang in die Kanalisation abgepumpt. Trotz Konstruktiver und verfahrenstechnischer Maßnahmen ist der Wasser-, Energie- und Waschmittelverbrauch bei diesen Maschinen und Verfahren doch noch relativ hoch.In these generally known washing and centrifuging machines, the liquor used is pumped out into the sewer system after each washing cycle (pre-wash or main wash) or after each individual wash cycle. Despite constructive and procedural measures, the water, energy and detergent consumption of these machines and processes is still relatively high.
Zur Minimierung der Verbrauchswerte sind auch Trommelwaschmaschinen ohne Laugenbehälter bekannt, bei denen die Wasch- und/oder Spülflotten in einen Recylingbehälter gepumpt und von dort für eine nächste Wäschecharge noch einmal verwendet werden können. (siehe u.a. DD-PS 259 316, DD-PS 301 607) Für diese Maschinen ist jedoch ein aufwendiges und kompliziertes Heizungs-, Steuerungs- und Flottenführungssystem erforderlich, so daß derartige Einrichtungen noch keine marktfähige Realisierung erfahren haben.To minimize the consumption values, drum washing machines without a tub are also known, in which the washing and / or rinsing liquors are pumped into a recycling tank and from there can be used again for a next batch of laundry. (See, among others, DD-PS 259 316, DD-PS 301 607) For these machines, however, a complex and complicated heating, control and fleet management system is required, so that such devices have not yet been implemented on the market.
Weiterhin ist es bereits allgemeine Erkenntnis, daß beim Wäschewaschen, z.B. von Hand oder auch in technisch einfachen Wellenradwaschmaschinen, verschiedene Wäscheposten hintereinander in der selben Waschflotte gewaschen bzw. Spülflotte gespült werden. Dabei wird, um die Flotten intensiv auszunutzen, zuerst feines und/oder weißes bzw. wenig verschmutztes Waschgut gewaschen und anschließend mit der selben Flotte gröberes und/oder buntes bzw. stark verschmutztes Waschgut gewaschen.Furthermore, it is already common knowledge that when washing laundry, for example by hand or in technically simple wave wheel washing machines, different laundry items are washed in succession in the same washing liquor or rinsing liquor is rinsed. In order to make intensive use of the liquors, first fine and / or white or slightly soiled laundry is washed and then coarser and / or colorful or heavily soiled laundry is washed with the same liquor.
Dieser Verfahrensablauf ist jedoch bei den bisher bekannten programmgesteuerten Waschmaschinen nicht realisierbar.However, this process sequence cannot be implemented in the previously known program-controlled washing machines.
Einer zukunftsorientierten Einsparung an Trinkwasser, Elektroenergie und Waschmittel genügen diese Verfahren und Einrichtungen noch nicht im erforderlichen Umfang.These processes and facilities are not yet sufficient to meet future-oriented savings in drinking water, electrical energy and detergents.
Aufgabe der Erfindung ist es daher, für das Betreiben einer Waschmaschine, insbesondere einer Trommelwaschmaschine, gemäß dem Oberbegriff des Anspruches 1, ein Verfahren zu schaffen, mit dem die effektiven Verbrauchswerte je Einheit Waschgut ohne Verschlechterung des Waschergebnisses hinsichtlich der Reinigungs- und Spülwirkung weiter minimiert werden können.The object of the invention is therefore to provide a method for operating a washing machine, in particular a drum washing machine, according to the preamble of claim 1, with which the effective consumption values per unit of laundry are further minimized without deteriorating the washing result with regard to the cleaning and rinsing effect can.
Diese technische Aufgabe wird durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale gelöst.This technical problem is solved by the features specified in the characterizing part of claim 1.
Die Vorteile, die durch die Erfindung erreicht werden, bestehen darin, daß gegenüber den bekannten technischen Lösungen auf dem Gebiet der Trommelwaschmaschinen mit einem relativ geringen maschinentechnischen Mehraufwand der Verbrauch an Trinkwasser, Waschmittel, Elektroenergie für das Aufheizen der Waschflotte sowie der Zeitaufwand je Kilogramm Waschgut wesentlich reduziert wird.The advantages that are achieved by the invention are that compared to the known technical solutions in the field of drum washing machines with a relatively low mechanical engineering overhead, the consumption of drinking water, detergent, electrical energy for heating the washing liquor and the time required per kilogram of laundry are essential is reduced.
Insbesondere durch die waschtechnische Nutzung der zwei von einander unabhängigen Wasch- und Schleudertrommeln wird die spezifische Waschleistung, die als kg Waschgut pro Zeiteinheit definiert werden kann, bis zu 50 % erhöht, da - in wesentlich kürzerer Zeit das gesamte Waschgut gewaschen, gespült und mit einem gewissen Zeitversatz geschleudert wird - eine größere Wäschemenge bearbeitet werden kann.
Ein weiterer Vorteil wird darin gesehen, daß durch die Möglichkeit der Wiederverwendung von z.B. nur leicht verschmutzter Waschflotte aus der einen Kammer in der anderen, z.B. für die Vorwäsche von stark verschmutzter Wäsche, mit weniger Frischwassereinsatz und weniger Waschmittelzusatz der Verbrauch je Einheit Waschgut gesenkt werden kann.
Unter Beibehaltung der an sich bekannten optimal programmierten und textilartbezogenen Wasch-, Spül- und Schleuderverfahren können Einsparungen an Trinkwasser bis ca. 30 %, an Elektroenergie bis ca. 15 % sowie bis zu 10 % an Waschmittel und sonstigen Wäschepflegemitteln erzielt werden.In particular through the use of the two in terms of washing technology Independent washing and centrifuging drums increase the specific washing performance, which can be defined as kg of laundry per unit of time, by up to 50%, since - in a much shorter time, the entire laundry is washed, rinsed and spun with a certain delay - a greater one Amount of laundry can be edited.
Another advantage is seen in the fact that the possibility of reusing, for example, only lightly soiled washing liquor from one chamber in the other, for example for the prewashing of heavily soiled laundry, with less use of fresh water and less addition of detergent can reduce the consumption per unit of laundry .
While maintaining the well-known, optimally programmed and textile-type washing, rinsing and spinning processes, savings in drinking water of up to approx. 30%, in electrical energy up to approx. 15% and up to 10% in detergents and other laundry care products can be achieved.
Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens ergeben sich aus den übrigen Unteransprüchen und aus den nachfolgend beschriebenen Ausführungsbeispielen.Further advantageous refinements of the method according to the invention result from the remaining subclaims and from the exemplary embodiments described below.
In tabellarischer Form sind einige Möglichkeiten für eine sinnvolle Zusammenstellung von Wäschechargen bzw. Zuordnung dargestellt, wobei meistens das weniger verschmutzte und/oder pflegeleichte Waschgut, bei welchem bekannterweise die Wasch- und Spülvorgänge mit einem höheren Flottenniveau ablaufen, primär behandelt wird.
Die Primär-Waschflotte kann somit zumindest für eine sekundäre Vorwäsche von stärker verschmutztem Waschgut genutzt werden.
Es werden sämtliche Primär-Spülflotten für den sekundären Spülprozess nachgenutzt, so daß lediglich nur die letzte Sekundär-Spülflotte aus Frischwasser besteht, die gegebenenfalls wieder als Primär-Waschflotte für eine nächste Wäschecharge verwendet werden kann.
Über dieses tabellarische Beispiel hinaus, sind natürlich weitaus mehrere Wäschechargen-Kombinationen möglich.In tabular form, there are some options for a sensible combination of batches of laundry or assignment shown, mostly the less soiled and / or easy-care laundry, in which the washing and rinsing processes run with a higher liquor level, is primarily treated.
The primary wash liquor can thus be used at least for secondary prewashing of heavily soiled laundry.
All primary rinsing liquors are reused for the secondary rinsing process, so that only the last secondary rinsing liquor consists of fresh water, which can optionally be used again as the primary washing liquor for a next batch of laundry.
Beyond this tabular example, of course, several laundry batch combinations are possible.
Die Figur 1 zeigt in einer Prinzipdarstellung das grundsätzliche Flottenführungssystem (hier am Beispiel einer Waschmaschine mit zwei Topladersystemen).
Dabei können beide Systeme programmsteuerungstechnisch sowohl unabhängig als auch abhängig voneinander ausgelegt sein. Bei voneinander unabhängigen Systemen, d.h. die Programmabläufe von Primär- und Sekundärsystem sind unabhängig voneinander, ist die Programmierung der einzelnen Vorgänge bzw. Ansteuerung der einzelnen Baugruppen wie bei jeweils einer Einzel-Trommelwaschmaschine ausgelegt.
Mit dieser Verfahrensvariante kann der Hauptgebrauchswert des erfindungsgemäßen Zweitrommel-Waschverfahren, das gleichzeitige Waschen von unterschiedlichem Waschgut oder einer Waschgutcharge mit einer größeren Füllmasse ohne weiteres realisiert werden.FIG. 1 shows a basic illustration of the basic fleet management system (here using the example of a washing machine with two top loading systems).
In terms of program control technology, both systems can be designed both independently and as a function of one another. In the case of systems which are independent of one another, ie the program sequences of the primary and secondary systems are independent of one another, the programming of the individual processes or control of the individual assemblies is designed in the same way as for a single drum washing machine.
With this process variant, the main use value of the two-drum washing process according to the invention, the simultaneous washing of different items to be washed or a batch of laundry items with a larger filling mass can be easily realized.
Beispiele für die Durchführung des erfindungsgemäßen Verfahrens bei denen beide Einzeltrommelsysteme programmsteuerungsmäßig miteinander verbunden sind, werden prinzipmäßig in den Figuren 2 und 3 dargestellt.Examples of the implementation of the method according to the invention, in which both individual drum systems are connected to one another in terms of program control, are shown in principle in FIGS.
Das Betreiben bzw. der Programmablauf einer Waschmaschine die konstruktiv nach dem Zwei-Trommel-Prinzip aufgebaut ist, kann etwa wie folgt ablaufen:The operation or the program sequence of a washing machine, which is constructed according to the two-drum principle, can run as follows:
Die Trommel des Primärsystems wird mit einem Posten von ca. 2 kg Feinwäsche (z. B. Gardinen oder ähnliches Waschgut) beschickt und mittels der Programmwahleinrichtung das Programm "Feinwäsche" mit einer Waschtemperatur von 40 Grad C eingegeben.
Die Trommel des Sekundärsystems wird mit ca. 3,5 kg Buntwasche beschickt. Auf Grund des relativ starken Verschmutzungsgrades wird hier das Programm "Buntwäsche mit Vorwaschgang" und eine Temperatur von 40 Grad C gewählt. Nach ordnungsgemäßer Herstellung bzw. Prüfung der Anschlüsse an das Frischwasser- und Abwassersystem sowie an das elektrische Netz, Zugabe der Waschmittel und Wäschepflegemittel in die maschinenseitig vorgesehenen Behältnisse und Verschließen der Trommel- bzw. Gehäusedeckel erfolgt der Start des Programmablaufes.
Steuerungsmäßig kann vorgesehen sein, daß ein Startimpuls ausreichend ist, um zunächst das Primärsystem zu starten und daß automatisch, nach Ablauf einer vorgegebenen Zeiteinheit oder Erreichen bestimmter Parameter, wie Flottenniveau im Sekundärsystem oder Beendigung des Wasch- und Abpumpvorganges im Primärsystem, der Programmablauf im Sekundärsystem gestartet wird.
Das Steuerungssystem kann aber auch so ausgelegt sein, daß der Programmablauf im Sekundärsystem separat gestartet werden kann.
Das Ausführungsbeispiel ist so aufgebaut, daß nach der Beendigung des Wasch- und Heizvorganges die im Primärsystem vorhandene Flotte, unter Einschaltung eines Schleuderschrittes (dieser kann unter Umständen auch ausgeblendet sein), in das Sekundärsystem abgepumpt wird.The drum of the primary system is loaded with a lot of approx. 2 kg of delicates (e.g. curtains or similar laundry) and the program "Delicates" with a washing temperature of 40 degrees C is entered using the program selector.
The drum of the secondary system is loaded with approximately 3.5 kg of colored laundry. Due to the relatively high degree of soiling, the program "Colored laundry with pre-wash" and a temperature of 40 degrees C are selected. After the connections to the fresh water and sewage system and the electrical network have been properly established and checked, detergents and laundry care products have been added to the containers provided on the machine and the drum and housing covers have been closed Start of the program.
In terms of control, it can be provided that a start pulse is sufficient to start the primary system first and that the program sequence in the secondary system starts automatically after a specified time unit or certain parameters, such as fleet level in the secondary system or completion of the washing and pumping process in the primary system becomes.
The control system can also be designed so that the program sequence can be started separately in the secondary system.
The exemplary embodiment is constructed in such a way that, after the washing and heating process has ended, the liquor present in the primary system is pumped out into the secondary system, with the involvement of a spinning step (this can also be hidden under certain circumstances).
Während im Primärsystem der erste Spülgang mit zugefloßenem Frischwasser abläuft, wird im Sekundärsystem der Programmschritt "Vorwäsche" mit der bereits benutzten Waschflotte aus dem Primärsystem realisiert.
Nach Ablauf des Vorwaschganges wird die nunmehr in ihrer Waschkraft erschöpfte Waschflotte in die Kanalisation abgepumpt.
Nach Absolvierung des programmgemäß vorgegebenen Regimes des Spülganges 1 im Primärsystem, bei dem das Waschgut ggf. noch eine gewisse Wärmemenge aus dem Waschgang in die Spülflotte eingetragen hat, wird diese erste Spülflotte, welche auch noch einen relativ hohen Anteil an waschaktiven Substanzen enthält, unter Einschaltung eines Schleuderschrittes (dieser kann unter Umständen auch ausgeblendet sein), in das Sekundärsystem abgepumpt.
Unter Zufluß von Frischwasser läuft nun im Primärsystem der 2. Spülgang ab. Gleichzeitig wird im Senkundärsystem - ggf. unter einem Nachheizen bis zum Erreichen der gewählten Temperatur - der Hauptwaschgang mit der Spülflotte des 1. Spülganges aus dem Primärsystem absolviert, ggf. unter Zufluß einer gewissen Menge Frischwasser als Ausgleich bis zum vorgegebenen Flottenniveau. Anschließend wird die verbrauchte Waschflotte unter Einschaltung eines Schleuderschrittes in die Kanalisation gepumpt.
Die Spülflotte des primärseitigen 2. Spülganges wird - ebenfalls unter Einschalten eines ausblendbaren Schleuderschrittes - in das Sekundärsystem gepumpt und dort als Spülflotte für die Durchführung des 1. Spülganges, ggf. unter Nachfüllen einer gewissen Teilmenge von Frischwasser bis auf das vorgegebene Flottenniveau, genutzt.
In gleicher Weise erfolgt der 3. Spülgang im Primärsystem bzw. der 2. Spülgang in Sekundärsystem, d.h. es wird der 3. Spülgang im Primärsystem mit Frischwasser und etwas zeitlich versetzt der 2. Spülgang im Sekundärsystem mit der Spülflotte des 3. Spülganges aus dem Primärsystem durchgeführt.
Nach Abschluß des primärseitigen 3. Spülganges erfolgt dort das programmgemäß vorgegebene Endschleudern.While in the primary system the first rinse cycle with fresh water flowing in takes place, in the secondary system the "Prewash" program step is carried out with the wash liquor from the primary system that has already been used.
After the pre-wash cycle, the washing liquor, now exhausted in its washing power, is pumped out into the sewage system.
After completion of the program of the rinse cycle 1 in the primary system, in which the items to be washed may still have a certain amount of heat from the wash cycle in the wash liquor has entered, this first rinse liquor, which also contains a relatively high proportion of detergent-active substances, is pumped out into the secondary system with the involvement of a spinning step (this may also be hidden under certain circumstances).
The second rinse cycle now takes place in the primary system under the inflow of fresh water. At the same time, in the secondary system - if necessary with reheating until the selected temperature is reached - the main wash cycle with the wash liquor from the 1st wash cycle is completed from the primary system, if necessary with a certain amount of fresh water as compensation to the specified fleet level. The used washing liquor is then pumped into the sewage system with the involvement of a spinning step.
The rinse liquor of the primary 2nd rinse cycle is pumped into the secondary system - also by switching on a skidable skidding step - and is used there as a rinse liquor for carrying out the 1st rinse cycle, if necessary with topping up a certain amount of fresh water to the specified liquor level.
The 3rd rinse cycle in the primary system or the 2nd rinse cycle in the secondary system takes place in the same way, i.e. the 3rd rinse cycle in the primary system with fresh water and the 2nd rinse cycle in the secondary system with the wash liquor of the 3rd rinse cycle from the primary system carried out.
After completing the 3rd rinse on the primary side there the final spin as specified in the program.
Der 3. Spülgang im Sekundärsystem erfolgt unter Frischwasserzufuhr und schließt auch hier mit dem programmgemäß vorgegebenen Endschleudern ab.The 3rd rinse cycle in the secondary system is carried out with fresh water supply and also ends here with the final spin specified in the program.
In dem anhand des Schemas gemäß Fig. 3 dargestellten Ausführungsbeispiel soll im Primärsystem Buntwäsche mit einer Temperatur von 90 Grad C und im Sekundärsystem Buntwäsche mit einer Temperatur von 60 Grad C gewaschen werden. Hier muß nach dem programmgemäßen Ablauf des Hauptwaschganges im Primärsystem eine Flottentemperaturabsenkung von der erreichten Temperatur von nahe 90 Grad C auf die für das Sekundärsystem eingestellte Temperatur von 60 Grad C vorgenommen werden. Dies erfolgt unter Zufuhr von Frischwasser. Damit entfällt natürlich dar Aufheizen der Waschflotte im Sekundärsystem.In the exemplary embodiment shown on the basis of the diagram according to FIG. 3, colored laundry with a temperature of 90 degrees C is to be washed in the primary system and colored laundry with a temperature of 60 degrees C in the secondary system. After the program of the main wash cycle in the primary system, a liquor temperature reduction from the temperature reached of close to 90 degrees C to the temperature of 60 degrees C set for the secondary system must be carried out here. This is done with the supply of fresh water. This naturally eliminates the need to heat the wash liquor in the secondary system.
Die Spülgänge werden in analoger Weise wie zuvor beschrieben durchgeführt, d.h. die Spülgänge im Primärsystem werden jeweils mit Frischwasser durchgeführt und die Spülgänge 1 und 2 im Sekundärsystem jeweils mit den Spülflotten aus den Spülgängen 1 bzw. 2 dem Primärsystems.
Der 3. Spülgang im Sekundärsystem wird mit Frischwasser durchgeführt.
Das Drehzahlregime während der Spülgänge, d.h. Einschaltung von Schleuderschritten in den Um-bzw. Abpumpphasen, ist analog dem zuvor beschriebenen Ausführungsbeispiel ausgelegt.The rinse cycles are carried out in a manner analogous to that previously described, ie the rinse cycles in the primary system are each carried out with fresh water and the
The 3rd rinse in the secondary system is carried out with fresh water.
The speed regime during the rinse cycles, ie switching on spinning steps in the reversing or. Drain phases, is designed analogously to the previously described embodiment.
Bei Durchführung der Wasch- und Spülgänge in der bisher schon bekannten Optimierung können somit folgende Effekte, der Rangfolge nach gestaffelt, erzielt werden:
- Einsparung von Zeit je kg Waschgut
- verbesserte Bedienung - Waschkomfort
- Einsparung von Energie, Frischwasser sowie Waschmittel und Wäsche-Pflegemittel je kg Waschgut
- trocknergerechte Portionierung des Waschgutes.
- Saving time per kg of laundry
- improved operation - washing comfort
- Saving energy, fresh water as well as detergent and laundry care products per kg of laundry
- Portion of the items to be tumble-dried.
