Description

Die Erfindung bezieht sich auf eine Zusatzeinrichtung für Waschmaschinen, welche ohne Eingriff in eine in der Waschmaschine vorhandene Steuerung extern angeordnet ist und welche einen Netzanschluß für die Waschmaschine auf­weist.The invention relates to an additional device for washing machines, which is arranged externally without intervention in a control existing in the washing machine and which has a mains connection for the washing machine.

Die Programme heutiger Waschmaschinen entsprechen nicht den in jüngster Zeit gestiegenen Anforderungen an eine Minimierung des Verbrauches von Energie, Wasser und Waschmittel. Eine Verringerung dieser Verbräuche führen nicht nur zu einer Kostenersparnis, sondern auch zu einer Umweltentlastung.The programs of today's washing machines do not meet the recently increased requirements for minimizing the consumption of energy, water and detergents. Reducing this consumption not only leads to cost savings, but also to environmental benefits.

Eine sehr einfache Möglichkeit der Einsparung von Wasch­mittel und Energie liegt darin, den Hauptwaschvorgang in festgesetzten Zeitabständen immer wieder zu unterbre­chen. Dadurch löst sich das Waschmittel besser auf, so daß auf Seifenbasis hergestellte Waschmittel benutzt werden können. Weiterhin kann mit geringerer Wassertempe­ratur gewaschen werden. Die auf dem Markt erhältliche Zu­satzeinrichtung besitzt lediglich eine Schaltuhr, welche man, nachdem die Vorwäsche beendet ist, auf eine be­stimmte Zeit stellt, damit bis zur Beendigung der ablau­fenden Zeit warmes Wasser einlaufen kann (ohne Tempera­turkontrolle).A very simple way of saving detergent and energy is to interrupt the main washing process again and again at fixed intervals. As a result, the detergent dissolves better, so that detergents based on soap can be used. You can also wash with a lower water temperature. The additional equipment available on the market only has a timer, which is set to a certain time after the prewash has ended, so that warm water can run in until the end of the expiring time (without temperature control).

Weiterhin befindet sich ein weiteres Gerät auf dem Markt, bei dem die Waschmaschine in Zeitintervallen ge­steuert wird (ohne weitere Einrichtungen).There is also another device on the market in which the washing machine is controlled at time intervals (without any other equipment).

Der Erfindung liegt die Aufgabe zugrunde, eine Zusatzein­richtung der eingangs genannten Art so auszubilden, daß ohne Eingriff in die Steuerung der Waschmaschine eine möglichst weitgehende Optimierung des Verbrauches an Energie, Wasser und Waschmittel erreicht wird.The invention has for its object to provide an additional device of the type mentioned so that the greatest possible optimization of the consumption of energy, water and detergent is achieved without intervention in the control of the washing machine.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zum Anschließen an den Wassereinlauf der Waschmaschine ein Mischer mit einem Warmwasseranschluß und Kaltwasser­anschluß und weiterhin ein Drucksensor und ein Tempe­ratursensor vorgesehen sind, daß die Zusatzeinrichtung ein Steuergerät hat, in dem ein die Stromaufnahme der Waschmaschine ermittelnder Strommesser angeordnet ist und daß das Steuergerät einen Rechner zum Unterbrechen der Stromversorgung der Waschmaschine aufgrund der Infor­mationen über ihre Stromaufnahme und der Drucksignale aufweist.This object is achieved in that a mixer with a hot water connection and cold water connection and further a pressure sensor and a temperature sensor are provided for connection to the water inlet of the washing machine, that the additional device has a control unit in which an ammeter determining the current consumption of the washing machine is arranged and that the control device has a computer for interrupting the power supply of the washing machine on the basis of the information about its current consumption and the pressure signals.

Eine solche Zusatzeinrichtung ist in der Lage, aufgrund der ihr zugeführten Informationen über den Strombedarf der Waschmaschine und der Druckstöße im Wassereinlauf die Waschmaschine optimal zu steuern, ohne daß in die in der Waschmaschine vorhandene Steuerung eingegriffen wer­den muß. Die Zusatzeinrichtung kann zum Beispiel durch Steuerung von Magnetventilen des Mischers aufgrund von Temperatursignalen eines zusätzlichen Temperatursensors dafür sorgen, daß der Waschmaschine für ihr gewünschtes Waschprogramm Wasser mit der richtigen Temperatur zuge­führt wird, so daß die elektrische Heizung der Wasch­maschine nicht arbeiten muß. Nur wenn die Wassertempe­ratur am Warmwasseranschluß nicht ausreicht, schaltet sich die Heizung der Waschmaschine automatisch ein. Der Warmwasseranschluß kann beispielsweise von der Ölheizung oder von einem Solardach versorgt werden.Such an additional device is able to optimally control the washing machine on the basis of the information supplied to it about the power requirement of the washing machine and the pressure surges in the water inlet, without having to intervene in the control existing in the washing machine. The additional device can, for example, by controlling solenoid valves of the mixer on the basis of temperature signals from an additional temperature sensor, ensure that the washing machine is supplied with water at the correct temperature for its desired washing program, so that the electric heating of the washing machine does not have to work. Only if the water temperature at the hot water connection is not sufficient will the washing machine's heating switch on automatically. The hot water connection can be supplied by oil heating or a solar roof, for example.

Die Zusatzeinrichtung kann dadurch auf einfache Weise erkennen, ob beispielsweise in der Waschmaschine das Vor­waschprogramm oder Hauptwaschprogramm läuft, daß der Drucksensor zum Registrieren der beim Schließen des Was­sereinlaufes entstehenden Druckspitzen im Wassereinlauf der Waschmaschine ausgebildet und in dem Steuergerät ein Zähler zum Zählen der Druckstöße vorgesehen ist. Hier­durch ist die Zusatzeinrichtung in der Lage zu entschei­den, ob der Waschmaschine Wasser mit niedriger Tempera­tur für die Vorwäsche oder mit hoher Temperatur für die Hauptwäsche zugeführt werden muß.The additional device can thereby easily recognize whether, for example, the prewash program or main wash program is running in the washing machine, that the pressure sensor is designed to register the pressure peaks occurring when the water inlet closes, and a counter is provided in the control unit for counting the pressure surges. As a result, the additional device is able to decide whether the washing machine must be supplied with water at a low temperature for the prewash or at a high temperature for the main wash.

Die Waschmaschinenprogramme sind in der Regel so gestal­tet, daß für einen gewünschten Waschvorgang an einem beliebigen Punkt innerhalb des Waschmaschinenprogrammes begonnen werden kann. Man kann beispielsweise direkt mit der Hauptwäsche beginnen und anschließend das normale Waschprogramm mit den Spül- und Schleudervorgängen ab­laufen lassen. In solchen Fällen ist es natürlich erfor­derlich, daß die Zusatzeinrichtung den Einstiegspunkt in das Waschprogramm berücksichtigt. Das kann auf einfache Weise dadurch geschehen, daß das Steuergerät auf das je­weils gewählte Waschprogramm der Waschmaschine einstell­bar ausgebildet ist.The washing machine programs are usually designed so that a desired washing process can be started at any point within the washing machine program. For example, you can start directly with the main wash and then run the normal washing program with the rinsing and spinning processes. In such cases, it is of course necessary that the additional device takes into account the entry point into the washing program. This can be done in a simple manner in that the control device is designed to be adjustable to the washing program of the washing machine selected in each case.

Eine Waschmaschine vermag besonders umweltfreundlich mit der erfindungsgemäßen Zusatzeinrichtung zu arbeiten, wenn die Zusatzeinrichtung zugleich zum Steuern eines Regenwasseranschlusses für die Waschmaschine ausgebildet ist.A washing machine can work in a particularly environmentally friendly manner with the additional device according to the invention if the additional device is at the same time designed to control a rainwater connection for the washing machine.

Auch das ansich bekannte Unterbrechen des Hauptwaschvor­ganges in einstellbaren Zeitabständen kann von der Zu­satzeinrichtung gesteuert werden.Even the known interruption of the main washing process at adjustable time intervals can be controlled by the additional device.

Die gewünschte Verlängerung des Hauptwaschganges durch Pausenintervalle kann auf einfache Weise dadurch einge­stellt werden, daß das Steuergerät einen Zeitwahlschal­ter zum Einstellen der gewünschten Gesamtdauer der Unter­brechungen des Hauptwaschganges aufweist.The desired extension of the main wash cycle through interval intervals can be set in a simple manner in that the control device has a time selector switch for setting the desired total duration of the interruptions in the main wash cycle.

Auch eine Beeinflussung der für die gewünschten Wasch­vorgänge optimalen Temperatur ist auf einfache Weise dadurch möglich, daß das Steuergerät einen Temperatur­wahlschalter zum Einstellen der beim Hauptwaschgang gewünschten Wassertemperatur aufweist.It is also possible in a simple manner to influence the optimum temperature for the desired washing processes in that the control device has a temperature selection switch for setting the water temperature desired during the main washing cycle.

Überflutungen des Raumes durch Defekte an der Waschma­schine können ebenfalls mit der erfindungsgemäßen Zusatz­einrichtung ausgeschlossen werden, indem die Zusatzein­richtung einen Wasserwächter zum Erfassen von sich auf dem Fußboden sammelndem Wasser aufweist und der Rechner zum Abschalten jeglicher Wasserzufuhr und Stromzufuhr zur Waschmaschine ausgebildet ist.Flooding of the room due to defects in the washing machine can also be ruled out with the additional device according to the invention, in that the additional device has a water monitor for detecting water collecting on the floor and the computer is designed to switch off any water supply and power supply to the washing machine.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon schematisch in der Zeichnung dargestellt und wird nachfolgend beschrieben.The invention allows numerous embodiments. To further clarify its basic principle, one of them is shown schematically in the drawing and is described below.

Die Zeichnung zeigt die Umrisse einer Waschmaschine 1, welche einen üblichen Wassereinlauf 2 und ein Netzkabel 3 mit einem Netzstecker 4 hat. Am Wassereinlauf 2 ist ein Mischer 5 angeschlossen, der mit einem Warmwasser­anschluß 6 und einem Kaltwasseranschluß 7 verbunden ist. Magnetventile 8, 9 vermögen die Menge des einfließenden kalten und warmen Wassers zu steuern. In die Verbindung vom Mischer 5 zum Wassereinlauf 2 sind weiterhin ein Temperatursensor 10 und ein Drucksensor 11 geschaltet.The drawing shows the outline of a washing machine 1, which has a conventional water inlet 2 and a power cord 3 with a power plug 4. At the water inlet 2, a mixer 5 is connected, which is connected to a hot water connection 6 and a cold water connection 7. Solenoid valves 8, 9 can control the amount of cold and warm water flowing in. A temperature sensor 10 and a pressure sensor 11 are also connected in the connection from the mixer 5 to the water inlet 2.

Wichtig für die Erfindung ist weiterhin ein Steuergerät 12, welches einen Netzstecker 13 und einen Steckkontakt 14 hat. In diesen Steckkontakt 14 kann der Netzstecker 4 der Waschmaschine 1 gesteckt werden, damit diese über das Steuergerät 12 mit elektrischer Energie versorgt werden kann. Nicht dargestellt ist en Rechner in dem Steuergerät 12, welcher aufgrund der Temperatursignale des Temperatursensors 10, der Drucksignale des Druck­sensors 11 und der Information über die Leistungsauf­nahme der Waschmaschine, die ein in dem Steuergerät ein­gebauter Strommesser liefert, die Stromzufuhr zur Wasch­maschine 1 steuert.Also important for the invention is a control unit 12 which has a mains plug 13 and a plug contact 14. The mains plug 4 of the washing machine 1 can be plugged into this plug contact 14 so that it can be supplied with electrical energy via the control device 12. Not shown is a computer in the control unit 12, which controls the power supply to the washing machine 1 on the basis of the temperature signals of the temperature sensor 10, the pressure signals of the pressure sensor 11 and the information about the power consumption of the washing machine, which is supplied by an ammeter installed in the control unit.

Auf der Vorderseite des Steuergerätes 12 ist ein Wahl­schalter 15 vorgesehen, mit dem man entsprechend der an der Waschmaschine 1 vorgenommenen Einstellung einstellen kann, mit welchem Waschvorgang das Programm starten soll. Weiterhin hat das Steuergerät 12 einen Zeitschal­ter 16, mit dem die Gesamtdauer der Unterbrechungen des Hauptwaschvorganges eingestellt werden kann. Zusätzlich ist ein Temperaturschalter 17 vorgesehen, der eine Ein­stellung der Temperatur des der Waschmaschine 1 zuge­führten Wassers erlaubt.A selector switch 15 is provided on the front of the control device 12, with which one can set the washing process with which the program is to start, in accordance with the setting made on the washing machine 1. Furthermore, the control device 12 has a timer 16, with which the total duration of the interruptions in the main washing process can be set. In addition, a temperature switch 17 is provided, which allows the temperature of the water supplied to the washing machine 1 to be adjusted.

Für den Fall, daß die Waschmaschine 1 Regenwasser nutzen soll, ist am Mischer 5 ein Regenwasseranschluß 18 vor­gesehen, über den, von einem Magnetventil 19 gesteuert, anstelle von Trinkwaser vom Kaltwasseranschluß 7 der Waschmaschine Regenwasser zugeführt werden kann. Trink­wasser wird dann nur für den letzten Spülvorgang ver­wendet.In the event that the washing machine 1 is to use rainwater, a rainwater connection 18 is provided on the mixer 5, via which, controlled by a solenoid valve 19, rainwater can be supplied from the cold water connection 7 to the washing machine instead of drinking water. Drinking water is then only used for the last rinsing process.

Überflutungen des Raumes mit der Waschmaschine 1 können durch einen üblichen Wasserwächter 20 ausgeschlossen werden, der auf dem Fußboden des Aufstellungsraumes der Waschmaschine 1 anzuordnen und an das Steuergerät 12 angeschlossen ist.Flooding of the room with the washing machine 1 can be prevented by a conventional water monitor 20, which is to be arranged on the floor of the installation space of the washing machine 1 and is connected to the control unit 12.
