Die Erfindung betrifft insbesondere ein Haushaltsgerät mit einem Gehäuse, einem Behandlungsraum für zu behandelnde Gegenstände, einer Steuerungseinheit und einer Türeinheit zum Öffnen und Verschließen des Behandlungsraums, wobei die Türeinheit ein Zentralelement und ein Randelement aufweist, und wobei das Randelement zumindest in einer unteren Hälfte der Türeinheit angeordnet ist und dem Zentralelement derart vorgelagert ist, dass Zentralelement und Randelement einen Winkel α im Bereich von 10° bis 85° bilden, und einer Projektionsvorrichtung, sowie ein besonders geeignetes Verfahren zum Betrieb des Haushaltsgerätes.The invention relates to a household appliance with a projection device and a method for its operation. The invention relates in particular to a household appliance with a housing, a treatment room for objects to be treated, a control unit and a door unit for opening and closing the treatment room, the door unit having a central element and an edge element, and the edge element at least in a lower half of the door unit is arranged and upstream of the central element in such a way that the central element and the edge element form an angle α in the range from 10 ° to 85 °, and a projection device, as well as a particularly suitable method for operating the household appliance.
Die optische Anzeige von Informationen ist für einen benutzerfreundlichen Betrieb eines Haushaltsgerätes von großer Bedeutung geworden. Zur Bedienung von Haushaltsgeräten wie Waschmaschinen, Trocknern oder Herden werden außerdem zunehmend berührungsempfindliche Bedieneinrichtungen, insbesondere auch externe Bedieneinrichtungen eingesetzt. Eine solche berührungsempfindliche Bedieneinrichtung kann beispielsweise ein Smartphone oder auch ein Tablet-Computer sein. Diese weisen in der Regel einen Touchscreen auf, welcher eine Anzeigeeinrichtung mit einer Bedieneinrichtung kombiniert. Die Bedienung des Haushaltsgeräts findet dann meist über eine App statt. Obwohl auf diese Weise eine rasche Bedienung des Haushaltsgeräts möglich ist, sind die auf Smartphones und Tablet-PCs zur Verfügung stehenden Touchscreens meist sehr klein. Die in Haushaltsgeräten zur Verfügung stehende Technik ist über die Jahre jedoch immer ausgefeilter und die Bedienung somit immer komplexer geworden. Die übersichtliche Darstellung von komplexen Inhalten auf kleinen Touchscreens stellt daher eine Herausforderung dar. Es wäre wünschenswert, zusätzlich eine Möglichkeit an einem Haushaltsgerät bereitzustellen, komplexe Inhalte auf einer größeren Fläche darzustellen. Aber auch bei Haushaltsgeräten mit einer stationären Bedieneinrichtung, auch als Bedieneinheit bezeichnet, wäre eine verbesserte Darstellung von Informationen über den Betrieb des Haushaltsgerätes sinnvoll.The visual display of information has become of great importance for user-friendly operation of a household appliance. To operate household appliances such as washing machines, dryers or stoves, touch-sensitive operating devices, in particular external operating devices, are also increasingly being used. Such a touch-sensitive operating device can be, for example, a smartphone or a tablet computer. These usually have a touchscreen which combines a display device with an operating device. The household appliance is then mostly operated via an app. Although the household appliance can be operated quickly in this way, the touchscreens available on smartphones and tablet PCs are usually very small. However, the technology available in household appliances has become more and more sophisticated over the years, making operation more and more complex. The clear display of complex content on small touchscreens is therefore a challenge. It would be desirable to additionally provide a possibility on a household appliance to display complex content on a larger area. But even in the case of household appliances with a stationary operating device, also referred to as an operating unit, an improved display of information about the operation of the household appliance would make sense.
Haushaltsgeräte mit einer projizierten Anzeige von Einstellungen und Einstellungsmöglichkeiten des Haushaltsgerätes sind bereits bekannt.Household appliances with a projected display of settings and setting options for the household appliance are already known.

Bei den bekannten Haushaltsgeräten ist allerdings häufig eine im Türbereich dargestellte, insbesondere projizierte Information nicht gut erkennbar, insbesondere wenn man berücksichtigt, dass ein Benutzer des Haushaltsgerätes, z.B. eines wasserführenden Haushaltsgerätes wie einer Waschmaschine oder eines Trockners, zumeist von oben auf das Haushaltsgerät schaut. Außerdem wäre es sinnvoll, wenn das Haushaltsgerät auf eine verbesserte Weise Informationen über eingestellte und einstellbare Behandlungsprogramme und deren Parameter darstellten könnte.In the known household appliances, however, information displayed, in particular projected, in the door area is often not easily recognizable, especially when one takes into account that a user of the household appliance, e.g. a water-bearing household appliance such as a washing machine or dryer, usually looks at the household appliance from above. In addition, it would make sense if the household appliance could present information about set and adjustable treatment programs and their parameters in an improved manner.

Zentralelement und Randelement können getrennte Elemente sein oder eine Einheit bilden. Vorzugsweise sind Zentralelement und Randelement einstückig ausgestaltet. Dabei können Zentralelement und Randelement aus dem gleichen oder verschiedenen Materialien bestehen. Vorzugsweise sind Zentralelement und Randelement jedoch unterschiedlich ausgestaltet, derart, dass sie sich in den optischen Eigenschaften unterscheiden. Vorzugsweise ist nämlich das Zentralelement zumindest teilweise transparent, während das Randelement vorzugsweise für die Verwendung mit einer Projektionsvorrichtung optimiert ist, indem beispielsweise eine projizierte optische Anzeige besonders deutlich wahrnehmbar ist.The central element and the edge element can be separate elements or form a unit. The central element and the edge element are preferably designed in one piece. The central element and the edge element can consist of the same or different materials. However, the central element and the edge element are preferably designed differently in such a way that they differ in their optical properties. This is because the central element is preferably at least partially transparent, while the edge element is preferably optimized for use with a projection device in that, for example, a projected optical display can be particularly clearly perceived.
Das erfindungsgemäße Haushaltsgerät enthält eine Projektionsvorrichtung. Die Projektionseinrichtung umfasst im Allgemeinen einen Projektor oder einen Beamer, sowie optische Mittel zur Positionierung der Projektion. Optische Mittel sind dabei im Allgemeinen z.B. Reflektoren, Linsen und Kollimatoren. Die Positionierung des Projektors oder Beamers innerhalb des Gehäuses des Haushaltsgeräts ist erfindungsgemäß nicht eingeschränkt. Allerdings ist in einer bevorzugten Ausführungsform des erfindungsgemäßen Haushaltsgerätes die Projektionsvorrichtung außerhalb des Behandlungsraums im Gehäuse oberhalb der Türeinheit angeordnet. Bei einer hierzu alternativen bevorzugten Ausführungsform des erfindungsgemäßen Haushaltsgerätes ist die Projektionsvorrichtung außerhalb des Behandlungsraums in einer oberen Hälfte der Türeinheit angeordnet.The household appliance according to the invention contains a projection device. The projection device generally comprises a projector or a beamer, as well as optical means for positioning the projection. Optical means are generally e.g. reflectors, lenses and collimators. The positioning of the projector or beamer within the housing of the household appliance is not restricted according to the invention. However, in a preferred embodiment of the household appliance according to the invention, the projection device is arranged outside the treatment room in the housing above the door unit. In an alternative preferred embodiment of the household appliance according to the invention, the projection device is arranged outside the treatment room in an upper half of the door unit.
Überdies ist ein Haushaltsgerät bevorzugt, bei dem das Randelement mit einer Aufstellfläche des Haushaltsgerätes einen Winkel β im Bereich von 10° bis 80°, vorzugsweise im Bereich von 20° bis 70°, bildet. Hierbei wird davon ausgegangen, dass eine untere Kante des Haushaltsgerätes im Allgemeinen parallel zur Aufstellfläche des Haushaltsgerätes ist und damit für die Bestimmung des Winkels β herangezogen werden kann. In Hinblick auf die Anordnung der Türeinheit wird hierzu insbesondere eine seitliche Kante des Haushaltsgerätes herangezogen.In addition, a household appliance is preferred in which the edge element forms an angle β in the range from 10 ° to 80 °, preferably in the range from 20 ° to 70 °, with a set-up surface of the household appliance. It is assumed here that a lower edge of the household appliance is generally parallel to the installation surface of the household appliance and can therefore be used to determine the angle β. With regard to the arrangement of the door unit, a lateral edge of the household appliance is used in particular for this purpose.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Haushaltsgeräts sind zur Erhöhung des Kontrasts der optischen Anzeige das Randelement und/oder die Projektionsfläche mindestens in einem Teilbereich abgedunkelt oder gefärbt. Die Realisierung der Abdunkelung oder Färbung ist erfindungsgemäß nicht eingeschränkt. Es kann sich dabei um eine Modifikation des Materials des Randelementes handeln, beispielsweise bei Glas durch eine Transmissionsänderung, aber auch um einen zusätzlichen Materialauftrag, beispielsweise in Form einer Beschichtung oder Folie.In a preferred embodiment of the household appliance according to the invention, the edge element and / or the projection surface are darkened or colored at least in a partial area to increase the contrast of the optical display. The implementation of the darkening or coloring is not restricted according to the invention. It can be a modification of the material of the edge element, for example in the case of glass by a change in transmission, but also an additional material application, for example in the form of a coating or film.
Erfindungsgemäß bevorzugt ist ein Haushaltsgerät, welches einen Bewegungssensor enthält, der die Anwesenheit eines Benutzers in der Nähe des Haushaltsgeräts feststellen kann, wobei die Steuerungseinheit dann eingerichtet ist, bei einer festgestellten Anwesenheit eine für diesen Fall vorgegebene Betriebsweise der Projektionsvorrichtung zu veranlassen. Beispielsweise könnte vorgesehen sein, dass eine optische Anzeige nur erfolgt, wenn ein Benutzer in der Nähe ist. Außerdem könnten Steuerungseinheit und Projektionsvorrichtung so aufeinander abgestimmt sein, dass die Helligkeit und/oder der Kontrast der optischen Anzeige von der Anwesenheit und ggf. vom Abstand des Benutzers vom Haushaltsgerät abhängig sind. Ein Bewegungssensor, insbesondere wenn dieser als Kamera ausgestaltet ist und/oder über eine geeignete zugeordnete Software verfügt, kann vorteilhaft auch für eine Gestensteuerung des Haushaltsgerätes verwendet werden. Die "Nähe" kann eine fest eingestellte oder durch einen Benutzer in Abhängigkeit vom Aufstellungsort einstellbare Größe sein, wobei ggf. die Entfernung und/oder die Größe des sich bewegenden Objektes (Benutzers) berücksichtigt werden kann.According to the invention, a household appliance is preferred which contains a motion sensor which can determine the presence of a user in the vicinity of the household appliance, the control unit then being set up to initiate a predetermined operating mode of the projection device when a presence is detected. For example, it could be provided that a visual display only takes place when a user is in the vicinity. In addition, the control unit and the projection device could be matched to one another in such a way that the brightness and / or the contrast of the optical display are dependent on the presence and possibly on the distance of the user from the household appliance. A motion sensor, in particular if it is designed as a camera and / or has suitable assigned software, can advantageously also be used for gesture control of the household appliance. The "proximity" can be a fixed value or a variable that can be set by a user depending on the installation location, with the distance and / or the size of the moving object (user) being able to be taken into account.
In Hinblick auf eine vorteilhafte Vernetzung von mehreren Haushaltsgeräten ist es erfindungsgemäß bevorzugt, dass das Haushaltsgerät eine Netzwerkschnittstelle aufweist, über welche es in ein Heimnetzwerk, das mindestens ein zweites Haushaltsgerät aufweist, integrierbar ist. Dann ist die Steuerungseinheit vorzugsweise eingerichtet, um auf dem erfindungsgemäßen Haushaltsgerät Informationen über das zweite Haushaltsgerät und/oder ein im zweiten Haushaltsgerät ablaufendes Programm auf der Projektionsfläche anzuzeigen.With regard to an advantageous networking of several household appliances, it is preferred according to the invention that the household appliance has a network interface via which it can be integrated into a home network which has at least one second household appliance. The control unit is then preferably set up to display information about the second household appliance and / or a program running in the second household appliance on the projection surface on the household appliance according to the invention.
Erfindungsgemäß ist ein Haushaltsgerät bevorzugt, bei dem die Türeinheit mindestens teilweise transparent ist, so dass sie die Beobachtung des Behandlungsraums durch einen Benutzer ermöglicht. Vorzugsweise ist dabei die Zentraleinheit zumindest teilweise, insbesondere vollständig, transparent, und das Randelement im Wesentlichen lichtundurchlässig, insbesondere vollständig lichtundurchlässig. Dabei ist das Randelement vorzugsweise so ausgestaltet, dass ein lichtundurchlässiger Teil als Projektionsfläche geeignet ist.According to the invention, a household appliance is preferred in which the door unit is at least partially transparent so that it enables a user to observe the treatment room. In this case, the central unit is preferably at least partially, in particular completely, transparent, and the edge element is essentially opaque, in particular completely opaque. The edge element is preferably designed such that an opaque part is suitable as a projection surface.
In einer weiteren bevorzugten Ausführungsform enthält das Haushaltsgerät einen Lichtsensor, welcher die Lichtstärke LU in einer Umgebung des Haushaltsgeräts detektieren kann, und die Steuerungseinheit ist eingerichtet, um bei einem Unterschreiten eines Minimalwerts LUmin eine Helligkeit der optischen Anzeige zu erhöhen und/oder bei einem Überschreiten eines Maximalwerts LUmax den Kontrast der optischen Anzeige zu erhöhen.In a further preferred embodiment, the household appliance contains a light sensor which can detect the light intensity L U in the vicinity of the household appliance, and the control unit is set up to increase a brightness of the optical display when a minimum value L Umin is not reached and / or when a Exceeding a maximum value L Umax to increase the contrast of the optical display.
Das erfindungsgemäße Haushaltsgerät weist im Allgemeinen eine interne und/oder externe Bedieneinheit auf.The household appliance according to the invention generally has an internal and / or external operating unit.
In einer bevorzugten Ausführungsform des Haushaltsgerätes ist eine Bedieneinheit mittig auf einer Frontblende des Gehäuses angeordnet, wobei in der Bedieneinheit mindestens drei berührungsempfindliche Bedienelemente angeordnet sind, von denen mindestens zwei als Schieberegler ausgestaltet sind. Dabei ist vorzugsweise ein erstes berührungsempfindliches Bedienelement als hierarchisch höheres Bedienelement eingerichtet, welches die Auswahl eines im Haushaltsgerät durchzuführenden Behandlungsprogramms gestattet und die mindestens zwei Schieberegler sind eingerichtet, um die Einstellung von Programmparametern gestatten. In einer bevorzugten Anordnung der Bedienelemente sind diese in einer Reihe angeordnet, welche einen rechten Winkel mit den Schiebereglern bildet, die im Allgemeinen als längliche Schieberegler ausgebildet sind. Längliche Schieberegler weisen längliche Sensorelemente auf, in deren Längsrichtung sich ein zugeordneter Parameterwert kontinuierlich oder sprunghaft ändert, so dass der Parameterwert durch Berührung des länglichen Sensorelementes eingestellt werden kann.In a preferred embodiment of the household appliance, an operating unit is arranged centrally on a front panel of the housing, with at least three touch-sensitive operating elements being arranged in the operating unit, at least two of which are designed as slide controls. A first touch-sensitive control element is preferably set up as a hierarchically higher control element, which allows the selection of a treatment program to be carried out in the household appliance, and the at least two slide controls are set up to allow program parameters to be set. In a preferred arrangement of the operating elements, these are arranged in a row which forms a right angle with the slide controls, which are generally designed as elongated slide controls. Elongated slide controls have elongated sensor elements, in the longitudinal direction of which an assigned parameter value changes continuously or abruptly, so that the parameter value can be set by touching the elongated sensor element.
Die nicht ausgewählten oder auswählbaren Parameterwerte sind dann vorzugsweise auf der Projektionsfläche, d.h. in der optischen Anzeige, optisch zurückgesetzt, beispielsweise dunkler und/oder kleiner, dargestellt und die Auswählbarkeit durch die Steuereinrichtung blockiert.The unselected or selectable parameter values are then preferably displayed on the projection surface, i.e. in the optical display, optically set back, for example darker and / or smaller, and the ability to select them is blocked by the control device.
Für die Schieberegler sind prinzipiell zwei Möglichkeiten für die Benutzung vorhanden. So kann bei einer ersten Möglichkeit ein im Wesentlichen örtlich festes Berühren mit einer Einstelleinheit, insbesondere mit einem Finger, also gerade keine ziehende oder seitlich ablaufende Bewegung, als punktartige Berührung ausgewertet werden. Dem Ort der punktartigen Betätigung ist dann im Allgemeinen ein bestimmter Parameterwert zugeordnet, welcher dadurch eingestellt wird. Bei der zweiten Möglichkeit ist vorgesehen, dass zur Betätigung ein Finger aufgelegt wird und vor allem in einer ziehenden Bewegung entlang des länglichen Sensorelementes bewegt wird. Diese Betätigung geht also über eine punktartige Berührung hinaus. In Abhängigkeit von der Länge und/oder dem Anfangspunkt und Endpunkt der Betätigung bzw. der ziehenden länglichen Bewegung wird ein entsprechender Parameterwert eingestellt. Das längliche Sensorelement kann insbesondere ein segmentierter, durch eine Berührung verschiebbarer Slider sein, wobei die Segmente als solche einem Benutzer sichtbar sein können oder aber kontinuierlich aufeinander folgen.There are basically two ways of using the slide controls. In the case of a first possibility, essentially fixed contact with an adjustment unit, in particular with a finger, that is to say precisely none pulling or sideways movement can be evaluated as point-like contact. A specific parameter value is then generally assigned to the location of the point-like actuation, which is thereby set. In the second option, it is provided that a finger is placed on it for actuation and, above all, moved in a pulling movement along the elongated sensor element. This actuation goes beyond a point-like contact. A corresponding parameter value is set as a function of the length and / or the starting point and end point of the actuation or the pulling elongated movement. The elongated sensor element can in particular be a segmented slider that can be moved by touching, wherein the segments as such can be visible to a user or else they follow one another continuously.
Im erfindungsgemäßen Haushaltsgerät vorhandene Schieberegler sind vorzugsweise zueinander parallel angeordnet.Sliders present in the household appliance according to the invention are preferably arranged parallel to one another.
Im Allgemeinen ist im erfindungsgemäßen Haushaltsgerät auch ein Bedienelement vorhanden, mit welchem ein eingestelltes Behandlungsprogramm gestartet werden kann, d.h. ein Startelement. Falls die Bedienelemente in einer Reihe angeordnet sind, befinden sich das erste berührungsempfindliche Element und das Startelement vorzugsweise an entgegengesetzten Enden der Reihe.In general, the household appliance according to the invention also has an operating element with which a set treatment program can be started, i.e. a start element. If the operating elements are arranged in a row, the first touch-sensitive element and the start element are preferably located at opposite ends of the row.
Erfindungsgemäß ist ein Haushaltsgerät bevorzugt, bei dem auf der optischen Anzeige auf der Projektionsfläche den Bedienelementen zugeordnete Anzeigebereiche vorhanden sind, wobei der einem in Benutzung befindlichen Bedienelement zugeordnete Anzeigebereich optisch hervorgehoben wird. Im Allgemeinen gibt es für das Startelement keine Entsprechung auf der optischen Anzeige.According to the invention, a household appliance is preferred in which display areas assigned to the operating elements are present on the optical display on the projection surface, the display area assigned to an operating element in use being highlighted. In general, there is no equivalent on the visual display for the start element.
In einer bevorzugten Ausführungsform des Haushaltsgerätes weist die Türeinheit einen Türsensor auf und ist die Steuerungseinheit eingerichtet, um die optische Anzeige bei einem geöffneten Zustand der Türeinheit auszuschalten.In a preferred embodiment of the household appliance, the door unit has a door sensor and the control unit is set up to switch off the optical display when the door unit is open.
Ein Haushaltsgerät im Sinne der Erfindung ist ein wasserführendes Haushaltsgerät, ausgewählt aus der Gruppe bestehend aus Waschmaschine, Waschtrockner und Trockner. Zur Aufnahme und zur Behandlung der Gegenstände umfasst das Haushaltsgerät einen Behandlungsraum. Da das Haushaltsgerät eine Waschmaschine, ein Trockner oder ein Waschtrockner ist, kann der Behandlungsraum eine Trommel sein. Um zu behandelnde Gegenstände aufnehmen zu können, weist der Behandlungsraum eine Öffnung auf, durch welche hindurch er mit Gegenständen bestückt werden kann. Eine Behandlung der Gegenstände erfolgt im Allgemeinen unter Einwirkung von bestimmten Prozessbedingungen, sei es trocken-warme Prozessluft in einem Trockner oder Waschlauge in einer Waschmaschine. Es ist somit im Allgemeinen nötig, dass der Behandlungsraum während der Behandlung von Gegenständen verschlossen werden kann. Daher weist das erfindungsgemäße Haushaltsgerät eine Türeinheit zum Öffnen und Verschließen des Behandlungsraums auf. Die Ausgestaltung einer solchen Türeinheit ist neben den erfindungsgemäßen Vorgaben nicht eingeschränkt, aber im Allgemeinen abhängig von der Art des Haushaltsgeräts und der Art der Behandlung, welche im Behandlungsraum stattfindet, und somit der Ausgestaltung des Behandlungsraums. So hat die Türeinheit einer Waschmaschine in der Regel die Form eines vorzugsweise teilweise transparenten Bullauges. Jedenfalls sind Material, Dicke und Form der Türeinheit abhängig von der Art des Haushaltsgeräts. in welchem die Türeinheit verwendet wird.A household appliance in the sense of the invention is a water-bearing household appliance selected from the group consisting of washing machine, washer-dryer and dryer. For receiving and handling the objects, this includes Household appliance a treatment room. Since the household appliance is a washing machine, a dryer or a washer-dryer, the treatment space can be a drum. In order to be able to accommodate objects to be treated, the treatment room has an opening through which it can be equipped with objects. The objects are generally treated under the influence of certain process conditions, be it dry-warm process air in a dryer or washing liquor in a washing machine. It is therefore generally necessary that the treatment room can be locked during the treatment of objects. The household appliance according to the invention therefore has a door unit for opening and closing the treatment room. The design of such a door unit is not restricted in addition to the specifications according to the invention, but generally depends on the type of household appliance and the type of treatment that takes place in the treatment room, and thus the configuration of the treatment room. For example, the door unit of a washing machine generally has the shape of a preferably partially transparent porthole. In any case, the material, thickness and shape of the door unit are dependent on the type of household appliance. in which the door unit is used.
Erfindungsgemäß sind Projektionsvorrichtung und Projektionsfläche ausgebildet, um im Zusammenwirken mit der Steuerungseinheit des Haushaltsgerätes Text, Symbole, Muster und/oder Bilder darzustellen. Texte umfassen dabei Buchstaben, Zahlen und Sonderzeichen. Die Darstellung kann dabei sowohl in Farben, in Graustufen und/oder in Schwarz/Weiß erfolgen.According to the invention, the projection device and the projection surface are designed to display text, symbols, patterns and / or images in cooperation with the control unit of the household appliance. Texts include letters, numbers and special characters. The display can take place in colors, in gray levels and / or in black and white.
Gegenstand der Erfindung ist außerdem ein Verfahren zum Betrieb eines Haushaltsgeräts mit einem Gehäuse, einem Behandlungsraum für zu behandelnde Gegenstände, einer Steuerungseinheit und einer Türeinheit zum Öffnen und Verschließen des Behandlungsraums, wobei die Türeinheit ein Zentralelement und ein Randelement aufweist, und wobei das Randelement zumindest in einer unteren Hälfte der Türeinheit angeordnet ist und dem Zentralelement derart vorgelagert ist, dass Zentralelement und Randelement einen Winkel α im Bereich von 10° bis 85° bilden, und einer Projektionsvorrichtung, wobei das Randelement eine Projektionsfläche beinhaltet und die Steuerungseinheit eingerichtet ist, um mittels der Projektionsvorrichtung Informationen über ein im Haushaltsgerät durchführbares oder ablaufendes Behandlungsprogramm als optische Anzeige auf der Projektionsfläche darzustellen, das Randelement auch in einer oberen Hälfte der Türeinheit angeordnet ist und das Zentralelement umschließt, und das Haushaltsgerät ein wasserführendes Haushaltsgerät ist, ausgewählt aus der Gruppe bestehend aus Waschmaschine, Waschtrockner und Trockner,
umfassend die Schritte
- (a) Einschalten des Haushaltsgeräts, wobei bei einem geschlossenen Zustand der Türeinheit mittels der Projektionsvorrichtung auf der Projektionsfläche eine optische Anzeige von Informationen über ein im Haushaltsgerät durchführbares oder ablaufendes Behandlungsprogramm erfolgt;
- (b) Einstellen oder Verändern des Behandlungsprogramms, indem von auf einer Bedieneinheit angeordneten berührungsempfindlichen Bedienelementen zur Auswahl eines Behandlungsprogramms oder zur Einstellung eines Programmparameters ein Bedienelement ausgewählt wird; und
- (c) optische Anzeige von voreingestellten oder von einem Benutzer mittels der Bedienelemente ausgewählten Einstellungen eines Behandlungsprogrammes oder von Programmparametern auf den berührungsempfindlichen Bedienelementen zugeordneten Anzeigebereichen auf der Projektionsfläche, wobei der einem in Benutzung befindlichen Bedienelement zugeordnete Anzeigebereich optisch hervorgehoben wird.
comprehensive the steps
- (a) Switching on the household appliance, with information about a treatment program that can be carried out or running in the household appliance being displayed on the projection surface by means of the projection device when the door unit is closed;
- (b) setting or changing the treatment program by selecting an operating element from touch-sensitive operating elements arranged on an operating unit for selecting a treatment program or for setting a program parameter; and
- (c) Optical display of preset settings of a treatment program or of program parameters selected by a user by means of the operating elements on the display areas assigned to the touch-sensitive operating elements on the projection surface, the display area assigned to an operating element in use being highlighted.
Die Erfindung hat zahlreiche Vorteile. Eine optische Anzeige auf dem Randelement kann großflächig ausgelegt werden und ermöglicht in Ausführungsformen der Erfindung aufgrund des ebenfalls vorhandenen zumindest teilweise transparenten Zentralelementes trotzdem gleichzeitig die Beobachtung des Inneren eines Behandlungsraums durch einen Benutzer. Auf der im Vergleich zu einem Display auf einer Frontblende vergleichsweise größeren Fläche des Randelementes lassen sich Inhalte zudem in einer angenehm wahrnehmbaren Größe darstellen. Dies ist auf kleinen Touchscreens, wie sie auf Smartphones oder Tablet-PCs zu finden sind, oft nicht möglich. Zusätzlich ist für einen Benutzer insbesondere auch ein angenehmer Betrachtungswinkel möglich. Ein Benutzer kann in Ausführungsformen der Erfindung auch aus der Entfernung sofort erkennen, welche Behandlungsprogramme und Parameter eingestellt sind. Schließlich könnten mit der Projektionsvorrichtung im Randelement auch Warnhinweise bezüglich eines fehlerhaften Betriebes des Geräts angezeigt werden, so dass entsprechende Gegenmaßnahmen ergriffen werden könnten. Auch in einem dunklen Aufstellraum, bei Lichtausfall oder bei Einbruch der Nacht ist eine große und gut lesbare Darstellung von Inhalten oder ggf. von Warnhinweisen von Vorteil. Nicht zuletzt erleichtert eine vergrößerte Darstellung von Inhalten auf der optischen Anzeige die Bedienung des Haushaltsgeräts für Personen, welche in ihrer Sehkraft eingeschränkt sind. Schließlich eignet sich die Erfindung in Ausführungsformen besonders gut für den Einsatz in einem Hausnetzwerk, welches mehrere Haushaltsgeräte aufweist.The invention has numerous advantages. An optical display on the edge element can be designed over a large area and, in embodiments of the invention, due to the at least partially transparent central element also present, nevertheless enables a user to observe the interior of a treatment room at the same time. On the comparatively larger area of the edge element in comparison to a display on a front panel, content can also be displayed in a pleasantly perceptible size. This is often not possible on small touchscreens such as those found on smartphones or tablet PCs. In addition, a user can in particular also have a comfortable viewing angle. In embodiments of the invention, a user can immediately see from a distance which treatment programs and parameters have been set. Finally, the projection device in the edge element could also be used to display warnings relating to incorrect operation of the device, so that appropriate countermeasures could be taken. Even in a dark installation room If there is a light failure or nightfall, a large and easily legible display of content or, if necessary, warning notices is an advantage. Last but not least, an enlarged representation of content on the optical display facilitates the operation of the household appliance for people who are visually impaired. Finally, embodiments of the invention are particularly well suited for use in a house network which has several household appliances.
