Abstract
Description
Die Erfindung betrifft eine Datenübertragungsvorrichtung für Haushaltsmaschinen nach dem Oberbegriff des Anspruchs 1, eine Funktionskomponente für eine Haushaltsmaschine nach dem Oberbegriff des Anspruchs 8 sowie eine Haushaltsmaschine nach dem Oberbegriff des Anspruchs 12.The invention relates to a data transmission device for household machines according to the preamble of
Aus dem Stand der Technik sind handelsübliche Haushaltsmaschinen wie z.B. Waschmaschinen, Geschirrspüler, ggf. auch Kaffee- / Espressomaschinen oder dergleichen bekannt, bei denen einzelne, fest in die Haushaltsmaschine integrierte Funktionskomponenten Daten an andere fest integrierte Funktionskomponenten senden. Z.B. sendet die zentrale Steuerung eines Geschirrspülers an die fest in den Geschirrspüler integriere Kombidosiervorrichtung Befehle, welche Waschsubstanz wann gemäß dem abzuarbeitenden Reinigungsprogramm in den Arbeitsraum des Geschirrspülers abgegeben werden soll. Zu diesem Zweck sind die fest verbauten Funktionskomponenten üblicherweise miteinander fest verdrahtet.From the prior art commercial household appliances such. Washing machines, dishwashers, possibly also coffee / espresso machines or the like, in which individual, permanently integrated into the household appliance function components to send data to other permanently integrated functional components. For example, sends the central controller of a dishwasher to the integrated firmly in the dishwasher Kombidosiervorrichtung commands which washing substance should be delivered according to the cleaning program to be processed in the working space of the dishwasher. For this purpose, the permanently installed functional components are usually hardwired to each other.
Aufgabe der Erfindung ist es, eine Datenübertragungsvorrichtung für Haushaltsmaschinen, eine Funktionskomponente für eine Haushaltsmaschine bzw. eine Haushaltsmaschine vorzuschlagen, bei denen eine verbesserte Datenübertragung ermöglicht wird.The object of the invention is to propose a data transmission device for household appliances, a functional component for a household appliance or a household appliance, in which an improved data transmission is made possible.
Die Aufgabe wird, ausgehend von einer
Datenübertragungsvorrichtung, einer Funktionskomponente für eine Haushaltsmaschine sowie einer Haushaltsmaschine der eingangs genannten Art, durch die kennzeichnenden Merkmale der Ansprüche 1, 8 bzw. 12 gelöst.The task is, starting from a
Data transmission device, a functional component for a household appliance and a household appliance of the type mentioned, by the characterizing features of
Durch die in den abhängigen Ansprüchen genannten Maßnahmen sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich.The measures mentioned in the dependent claims advantageous embodiments and modifications of the invention are possible.
Dementsprechend zeichnet sich eine erfindungsgemäße Datenübertragungsvorrichtung für Haushaltsmaschinen dadurch aus, dass diese eine optische Schnittstelle aufweist. Vorteilhaft ist daran, dass z.B. gegenüber elektrischen Leitungen einer Festverdrahtung beim Eindringen von Wasser Kurzschlüsse vermieden werden können. Auch können teilweise doppelte Isolierungen, die bei elektrischen Geräten im Zusammenhang mit Wasser führenden Bauteilen verwendet werden, vermieden werden, insbesondere dann, wenn die Übertragung über längere Strecken erfolgen muss. Somit können auch Bauteile eingespart werden. Ferner ist bei optischen Übertragungen eine geringe Störrate, eine geringe Fehleranfalligkeit und eine geringe Verlustrate möglich. Zudem kann Energie eingespart werden, besonders dann, wenn eine lange Kabelführung einer elektrischen Leitung notwendig wäre, weil ein langes Kabel automatisch einen größeren elektrischen Widerstand aufweist als ein entsprechendes kürzeres.Accordingly, a data transmission device according to the invention for domestic appliances is characterized in that it has an optical interface. It is advantageous that e.g. against electrical wiring of a hard wiring ingress of water short circuits can be avoided. Also partially double insulation used in electrical equipment in connection with water-bearing components, can be partially avoided, especially if the transmission must be made over long distances. Thus, components can be saved. Furthermore, in the case of optical transmissions, a low interference rate, a low error rate and a low loss rate are possible. In addition, energy can be saved, especially if a long cable routing of an electrical line would be necessary because a long cable automatically has a greater electrical resistance than a corresponding shorter.
Erfolgt z.B. eine optische Übertragung zwischen einzelnen Komponenten, so können diese Komponenten oft ohne besonderen baulichen Aufwand gekapselt werden. Zur Herstellung einer elektrischen Verbindung zwischen beiden Komponenten ist es jedoch z.B. notwendig, eine Kabelverbindung zwischen beiden zu legen, welche die Kapselung dann wiederum durchbrechen würde. Es könnten zur Herstellung einer elektrischen Verbindung auch Außenkontakte an der jeweiligen Komponente vorgesehen sein. Diese können jedoch leicht korrodieren oder mit Ablagerungen wie Kalk besetzt sein. Diese Nachteile können wenigstens teilweise durch optische Schnittstellen grundsätzlich vermieden oder gemildert werden.If, for example, optical transmission takes place between individual components, then these components can often be encapsulated without any special construction effort. For the production of an electrical connection between the two components, however, it is necessary, for example, to lay a cable connection between the two, which would then in turn break the encapsulation. It could also be provided external contacts to the respective component for the preparation of an electrical connection. However, these can easily corrode or be covered with deposits such as lime. These disadvantages can be at least partially avoided or mitigated by optical interfaces.
Unter dem Begriff "Daten" sind Parameter, Befehle, Zahlen, also grundsätzlich alle möglichen Informationen zu verstehen. Eine Datenübertragung meint im Sinne der Erfindung ein Senden und/oder Empfangen von Daten. Die Datenübertragung kann demnach nur in einer Richtung oder aber als Austausch gegenseitig in beide Richtungen zwischen den Komponenten erfolgen.The term "data" is to be understood as meaning parameters, commands, numbers, ie basically all possible information. A data transmission in the sense of the invention means a transmission and / or reception of data. The data transmission can therefore take place only in one direction or as an exchange between each other in both directions between the components.
Haushaltsmaschinen im Sinne der Erfindung sind z.B. Geschirrspüler, Waschmaschinen oder dergleichen. Eine Funktionskomponente ist ein Bauteil bzw. eine Vorrichtung der Haushaltsmaschine, die eine oder mehrere bestimmte Funktionen erfüllt. Beispielsweise kann es sich dabei um die Kontrolleinheit der Haushaltsmaschine, also z.B. die zentrale Steuerungseinrichtung der Haushaltsmaschine handeln. Unter einer Kontrolle ist ein Steuer- und/oder Regelprozess zu verstehen. Eine Funktionskomponente kann aber auch z.B. die Bedienleiste der Haushaltsmaschine sein, über die der Benutzer der Haushaltsmaschine unter anderem z.B. das Reinigungsprogramm auswählen und einstellen kann. Funktionskomponente kann aber auch eine Kombidosiervorrichtung sein, die bei Geschirrspülern z.B. in der Beschickungstür der Maschine eingebaut ist und welche die entsprechenden Reinigungssubstanzen, Flüssigreiniger, Klarspüler, ggf. sogenannte Reinigungstabs oder Ähnliches in den Arbeitsraum der Haushaltsmaschine dosiert bzw. abgibt.Household machines according to the invention are e.g. Dishwashers, washing machines or the like. A functional component is a component or device of the household appliance that fulfills one or more specific functions. For example, it may be the control unit of the household appliance, e.g. the central control device of the household machine act. Control is a process of control and / or regulation. However, a functional component may also be e.g. the control bar of the household appliance, which the user of the household appliance, among other things, e.g. select and set the cleaning program. However, the functional component can also be a Kombidosiervorrichtung that in dishwashers, e.g. is installed in the loading door of the machine and which doses or dispenses the corresponding cleaning substances, liquid cleaner, rinse aid, possibly so-called cleaning rod or the like in the working space of the household appliance.
Regelmäßig sind die zentrale Kontrolleinheit der Haushaltsmaschine, die Bedienleiste und die Kombidosiervorrichtung als Funktionskomponenten fest in die Haushaltsmaschine eingebaut.Regularly, the central control unit of the household appliance, the control bar and the Kombidosiervorrichtung are permanently installed as functional components in the household appliance.
Ferner besteht aber auch die Möglichkeit, Funktionskomponenten zur Verfügung zu stellen, die nicht fest mit der Haushaltsmaschine verbaut sind. Beispielsweise können auch Dosiervorrichtungen als separater Dosiereinsatz in Haushaltsmaschinen verwendet werden. Bei Geschirrspülern können diese z.B. in den Arbeitsraum zusammen mit dem zu reinigenden Geschirr eingebracht werden. Die Dosiereinsätze können zudem die entsprechenden Reinigungs- bzw. Spülmittel bevorraten und während des Reinigungsvorgangs in den Arbeitsraum abgeben bzw. dosieren. Ein solcher Dosiereinsatz kann im Allgemeinen maschinengesteuert arbeiten, also eine Verbindung zur Kontrolleinheit der Haushaltsmaschine aufweisen, die wiederum die Dosierung des Dosiereinsatzes steuert bzw. regelt. Es ist auch denkbar, einen autark arbeitenden Dosiereinsatz zu verwenden. Im Gegensatz zum maschinengesteuerten besitzt dieser Dosiereinsatz z.B. Leitwert-, Temperatur-, pH-Sensoren oder dergleichen und bestimmt dadurch selbst, wann und auf welche Art und Weise Reinigungsmittel abgegeben werden müssen. Der Dosiereinsatz kann außerdem eine autarke Energieversorgung aufweisen. Es ist auch möglich, Dosiereinsätze vorzusehen, die nur teilweise unabhängig von der Kontrolleinheit der Haushaltsmaschine arbeiten, z.B. Daten an die Kontrolleinheit der Haushaltsmaschine übermitteln können, teilweise auch Befehle von der Kontrolleinheit der Haushaltsmaschine entgegennehmen können oder deren Energieversorgung von der Haushaltsmaschine abhängt.Furthermore, it is also possible to provide functional components that are not permanently installed with the household appliance. For example, metering devices can also be used as a separate metering insert in household machines. For dishwashers, for example, in the work room together with the zu cleaning dishes are introduced. The dosing units can also store the appropriate cleaning or rinsing agent and deliver or dose during the cleaning process in the work space. Such a metering insert can generally operate under machine control, ie have a connection to the control unit of the household appliance, which in turn controls or regulates the metering of the metering insert. It is also conceivable to use a self-sufficient metering insert. In contrast to the machine-controlled, this dosing unit has, for example conductivity, temperature, pH sensors or the like and thereby determines itself, when and in what way detergent must be dispensed. The dosing unit can also have a self-sufficient energy supply. It is also possible to provide Dosiereinsätze that work only partially independent of the control unit of the household machine, for example, can transmit data to the control unit of the household machine, partially accept commands from the control unit of the appliance or their energy supply depends on the appliance.
Eine optische Schnittstelle im Sinne der Erfindung ist eine Datenübertragungsstelle zur Verbindung von Geräten, Bauteilen oder dergleichen, welche durch Übertragung von Licht eine Übertragung von Daten, einen Austausch von Daten bzw. eine Kommunikation ermöglicht. Es ist denkbar, das eine erfindungsgemäße optische Schnittstelle grundsätzlich mit sichtbarem Licht (Wellenlangenbereich: 400 - 780 nm) arbeitet, aber auch optische Schnittstellen für infrarotes oder ultraviolettes Licht sind denkbar. Insbesondere kann die Wahl der Frequenz des Lichts darauf ausgelegt sein, im Arbeitsraum der Haushaltsmaschine etwa in Gegenwart von Wasser möglichst wenig gestört, z.B. absorbiert zu werden.An optical interface within the meaning of the invention is a data transfer point for connecting devices, components or the like, which by transmission of light enables a transmission of data, an exchange of data or a communication. It is conceivable that an optical interface according to the invention basically works with visible light (wavelength range: 400-780 nm), but also optical interfaces for infrared or ultraviolet light are conceivable. In particular, the choice of the frequency of the light may be designed to be as little disturbed in the working space of the household appliance as possible in the presence of water, e.g. to be absorbed.
Datenübertragungsvorrichtungen mit optischen Schnittstellen gemäß der Erfindung umfassen also z.B. entsprechende Sende- und/oder Empfangseinheiten. Diese können dabei z.B. bei einer einfachen Ausgestaltung der Erfindung als Photodiode auf der einen Seite und als Phototransistor auf der anderen Seite ausgebildet sein. Auch Optokoppler können bei Ausführungsformen der Erfindung als optische Schnittstellen Anwendung finden. Es ist zudem sowohl denkbar, die Lichtübertragung durch die Luft stattfinden zu lassen als auch Lichtwellenleiter bzw. Glasfaserleitungen zu verwenden, was insbesondere den Vorteil besitzt, dass z.B. Spritzwasser oder eingedrungenes Wasser, das auf die Leitungen gelangt, keinen oder zumindest nur gering die Übertragung des Lichts beeinflusst. Der Einsatz grundsätzlich aller Arten von Lichtübertragung sowie aller Arten von Sende- und/oder Empfangseinheiten für Licht ist denkbar.Data transmission devices with optical interfaces according to the invention thus include, for example, corresponding transmitting and / or receiving units. These can be used, for example, in a simple embodiment of the invention as a photodiode on the one side and be designed as a phototransistor on the other side. Optocouplers can also be used as optical interfaces in embodiments of the invention. It is also conceivable to allow the transmission of light through the air to take place as well as to use optical fibers or fiber optic cables, which has the particular advantage that, for example, splash or penetrated water that reaches the lines, no or at least only slightly the transmission of Light influences. The use of basically all types of light transmission as well as all types of transmitting and / or receiving units for light is conceivable.
Bei einer vorteilhaften Weiterbildung der Erfindung ist in der Haushaltsmaschine wenigstens eine Aufnahmevorrichtung vorgesehen, in der eine Funktionskomponente aufgenommen werden kann, insbesondere im Arbeitsraum der Haushaltsmaschine. Die Funktionskomponente kann dadurch in eine für ihren Betrieb günstige Position gebracht werden. Ferner kann auch die optische Schnittstelle so ausgerichtet werden, das die Lichtübertragung zur bzw. von der Funktionskomponente aus gezielt in Richtung einer weiteren optischen Schnittstelle geführt wird.In an advantageous development of the invention, at least one receiving device is provided in the household appliance, in which a functional component can be accommodated, in particular in the working space of the household appliance. The functional component can thereby be brought into a favorable position for their operation. Furthermore, the optical interface can also be aligned in such a way that the light transmission to or from the functional component is guided specifically in the direction of a further optical interface.
Besonders vorteilhaft ist es, die entsprechende Aufnahmevorrichtung so auszustatten, dass diese selbst die Datenübertragungsvorrichtung bzw. optische Schnittstelle umfasst. Die Funktionskomponente kann dabei so ausgebildet sein, dass deren Datenübertragungsvorrichtung genau an der entsprechenden Stelle angeordnet ist, um mit der Datenübertragungsvorrichtung in der Aufnahmevorrichtung zu kommunizieren. Der Vorteil ist darin zu sehen, dass der übertragungsweg sehr kurz, ggf. praktisch null, sein kann sowie ferner, dass dadurch die Gefahr störender Einflüsse, z.B. durch Spritzwasser auf der Übertragungsstrecke gering gehalten werden kann. Auch die Aufnahmevorrichtung so ausgebildet sein, dass eine Abschirmung für die Datenübertragungsvorrichtung bzw. optische Schnittstelle vorgesehen ist.It is particularly advantageous to equip the corresponding recording device in such a way that it itself comprises the data transmission device or optical interface. The functional component can be designed such that its data transmission device is arranged exactly at the corresponding point in order to communicate with the data transmission device in the recording device. The advantage lies in the fact that the transmission path can be very short, possibly virtually zero, and also that thereby the risk of disturbing influences, for example by splashing water on the transmission path can be kept low. Also, the receiving device be designed so that a shield for the data transmission device or optical interface is provided.
Bei einer vorteilhaften Weiterbildung der Erfindung besitzt die optische Schnittstelle auch noch weitere Zusatzfunktionen. Sie kann insbesondere als optisches Mess- und/oder Anzeigegerät genutzt werden, beispielsweise im Zusammenhang mit einem Vorratstank. Infolge der optischen Eigenschaften des dort bevorrateten Mediums kann auf diese Weise über die optische Schnittstelle erreicht werden, dass der zu überwindende optische Pfad je nach Füllstand unterbrochen ist oder durchleuchtet werden kann. Z.B. kann auch je nach Füllstand eine Intensitätsänderung des Lichts detektiert werden, etwa durch Absorption infolge des bevorrateten Mediums gegenüber einem leeren Tank, bei dem weniger absorbiert wird. Auch die Lichtbrechung oder -reflexion kann gemessen bzw. ausgenutzt werden, um Informationen über den Füllstand zu erhalten.In an advantageous development of the invention, the optical interface also has additional additional functions. It can be used in particular as an optical measuring and / or display device, for example in connection with a storage tank. As a result of the optical properties of the medium stored there, it is possible in this way to achieve, via the optical interface, that the optical path to be overcome is interrupted, depending on the fill level, or can be transilluminated. For example, can also be detected depending on the level of a change in intensity of the light, such as absorption due to the stored medium against an empty tank, in which less is absorbed. Also, the refraction or reflection of light can be measured or exploited to obtain information about the level.
Ferner kann auch die optische Schnittstelle als Anzeigegerät dienen. Falls nötig, kann die optische Schnittstelle auch aus vielen Sende- bzw. Empfangsstellen, etwa als Matrix angeordnet, dienen, von denen z.B. auch einige eine Messfunktion besitzen, während andere Sendepunkte (z.B. Lichtwellenleiterenden, die an eine Sendequelle angeschlossen sind) als Anzeige dienen.Furthermore, the optical interface can serve as a display device. If necessary, the optical interface can also be made up of many transmitting or receiving points, for example arranged as a matrix, of which e.g. some also have a measuring function while other transmitting points (e.g., optical fiber ends connected to a transmitting source) serve as an indication.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden unter Angabe weiterer Einzelheiten und Vorteile näher erläutert.An embodiment of the invention is illustrated in the drawings and will be explained in more detail below, with further details and advantages.

Zur Übertragung von Steuerbefehlen von der zentralen Steuerung 2 der Haushaltsmaschine zur Kombidosiervorrichtung 5 sind jeweils optische Schnittstellen 6, 7 vorgesehen, welche eine Datenübertragungsvorrichtung 8 bilden. Vorteilhaft ist an dieser Ausführungsvariante, dass die Übertragung baulich gesehen von einem feststehenden Teil der Haushaltsmaschine 1 auf einen beweglichen Teil, nämlich die Beschickungstür 3 erfolgt, welche zum Einräumen des Geschirrs in die Haushaltsmaschine geöffnet werden muss.For the transmission of control commands from the
Während des eigentlichen Betriebs, hier dem Reinigungsvorgang, ist die Beschickungstür 3 jedoch geschlossen und hat ihre feste Position. Jetzt ist die Übertragung zwischen den so angebrachten optischen Schnittstellen 6, 7 möglich, und zwar dann, wenn sie im Betrieb benötigt wird. Eine elektrische Leitungsführung wird nicht benötigt und auch elektrische Kontakte, die beim Öffnen der Beschickungstür unterbrochen werden, sind nicht notwendig. Solche elektrischen Kontakte könnten insbesondere leicht korrodieren oder durch wiederholtes Öffnen und Schließen der Tür mechanisch beschädigt werden, was dazu führen kann, dass der leitende Kontakt nach gewisser Zeit nicht mehr gewährleistet ist. Auch wäre ein elektrischer Kontakt zur Berührung mit der Hand ggf. zugänglich. Somit ermöglicht dieses Ausführungsbeispiel eine besonders sichere Ausgestaltung der Erfindung mit einer besonders sicheren Handhabung. Außerdem ermöglicht diese Ausführung eine hohe Langlebigkeit. Zudem kann die Datenübertragungsvorrichtung als Sensor verwendet werden, ob die Tür 3 offen oder geschlossen ist und somit ebenfalls zusätzlich eine Sicherheitseinrichtung darstellen, z.B. als Unterbrecher für die Spannungsversorgung. Dazu kann z.B. die optische Schnittstelle mit einer Art Relais gekoppelt sein, so dass bei unterbrochenem Lichtpfad die elektrische Spannungsversorgung gekappt wird.During the actual operation, here the cleaning process, the loading door 3 is closed and has its fixed position. Now, the transmission between the
Die Dosierkugel 16 kann z.B. dazu in der Lage sein, auf einen Befehl der Kontrolleinheit 11 hin zu dosieren; sie kann je nach Ausführungsform aber auch einfach geöffnet sein und beim Betrieb der Haushaltsmaschine sich entleeren. Es kann sich aber z.B. auch um eine reine Freund/Feind-Erkennung, also eine Codierung handeln, so dass über die optische Schnittstelle nur erkannt wird, ob es sich um eine für den Betrieb der Geschirrspülmaschine 10 zugelassene Dosierkugel 16 mit zugelassenem Reiniger darin handelt oder nicht. Dies kann zusätzlich auch durch eine Codierung bezüglich der mechanischen Aufnahme der Dosierkugel unterstützt werden. Die Dosierkugel 16 könnte aber auch in einer Ausführungsform eine Füllstandssensorik umfassen und anzeigen, ob sie voll oder leer ist. Ferner könnte eine Messvorrichtung in der Dosierkugel 16 integriert sein, die z.B. den gemessenen Leitwert und Temperatur an die Kontrolleinheit 11 weitergibt.For example, the
Die optische Schnittstelle 45 kann eine Reihe von Zusatzfunktionen erfüllen: Z.B. kann sie als Füllstandsmesser für den Tank 44 ausgebildet sein. Hierbei werden die optischen Eigenschaften des Mediums, z.B. des Flüssigreinigers oder Klarspülers genutzt. Die optische Schnittstelle kann so angeordnet oder ausgebildet sein, dass der optische Pfad, den das Licht über die optische Schnittstelle hinweg überwinden muss, je nach dem, ob der Tank gefüllt ist oder nicht, unterbrochen sein oder nicht. Die Lichtwellenleiter können aber auch so angeordnet sein, Brechungs- oder Reflexionseigenschaften des Flüssigreinigers bzw. Klarspülers ausgenutzt werden und so eine Füllstandsanzeige ermöglicht wird.The
Die optische Schnittstelle 45 kann auch, ggf. sogar zusätzlich zu einer weiteren Funktion wie der des Füllstandsmessers, als Anzeigevorrichtung verwendet werden. Hierzu kann die optische Schnittstelle so angeordnet werden, dass sie der Benutzer z.B. bei geöffneter Beschickungstür 41 wahrnehmen kann.The
