Description

Die Erfindung betrifft eine Bedieneinrichtung fĆ¼r ein HaushaltgerƤt, wie WƤschebehandlungsmaschine oder GeschirrspĆ¼ler, mit einem Blendenteil und zumindest einer Taste zur frontseitigen BetƤtigung von zumindest einem hinter dem Blendeteil angeordneten Schaltelement, und ferner einer Folie, die flƤchig auƟenseitig auf dem Blendenteil angeordnet.The invention relates to an operating device for a household appliance, such as laundry treatment machine or dishwasher, with a panel and at least one button for front-side actuation of at least one arranged behind the panel switching element, and further a film, the surface arranged on the outside of the panel part.

Die Erfindung betrifft ferner ein HaushaltgerƤt wie Waschmaschine, WƤschetrockner oder GeschirrspĆ¼ler mit einer Bedieneinrichtung, wie vorstehend beschrieben.The invention further relates to a domestic appliance such as a washing machine, tumble dryer or dishwasher with an operating device, as described above.

Bedienblenden mit Tasten sind bei HaushaltgerƤten allgemein bekannt. Mittels Tasten werden ausgewƤhlte Programme oder Programmoptionen vom Benutzer eingeschaltet bzw. aktiviert. Hierbei sind sogenannte Hubtasten bekannt, die eine eindeutige haptische RĆ¼ckmeldung an den Benutzer bereitstellen. Ein derartiges HaushaltgerƤt ist aus der DE 103 07 536 A1 bekannt. Hier ist eine Bedieneinrichtung fĆ¼r ein HaushaltgerƤt offenbart, die eine Bedienblende mit Tasten beinhaltet, welche jeweils einen StĆ¶ĆŸel bewegen. Die Tasten sind auf der AuƟenseite des Blendenteils angeordnet und mittels Filmscharnier einseitig gelagert. Hierdurch wird eine definierte Kippbewegung des jeweiligen Tasters um das Scharnier bereitgestellt.Control panels with buttons are well known in household appliances. Using keys, selected programs or program options are activated or activated by the user. Here, so-called lift buttons are known, which provide a clear haptic feedback to the user. Such a household appliance is from the DE 103 07 536 A1 known. Here, an operating device for a household appliance is disclosed, which includes a control panel with buttons, which each move a plunger. The keys are arranged on the outside of the panel part and mounted on one side by means of a film hinge. As a result, a defined tilting movement of the respective button is provided around the hinge.

Es sind ferner GerƤte, wie beispielswiese die Waschmaschine Adora SLX von der Firma V-Zug bekannt, die eine Folientastatur auf der Bedienblende besitzt. Die Folientastatur ist eben ausgebildet und bietet an den SchaltflƤchen einen Hub fĆ¼r die TastenbetƤtigung. Eine weitere Art, Tasten bereitzustellen, sind Touch-Bedienfelder, die ausgewƤhlte Bereiche aufweisen, die berĆ¼hrsensitiv ausgebildet sind und bei BerĆ¼hrung oder AnnƤherung der Fingerkuppe einen Schaltimpuls an eine Steuereinrichtung Ć¼bermitteln.There are also devices, such as the meadow Adora SLX from V-train known, which has a membrane keyboard on the control panel. The membrane keypad is flat and offers a stroke for the button operation on the buttons. Another way to provide keys are touch panels that have selected areas that are formed touch-sensitive and transmit a switching pulse to a control device upon contact or approach of the fingertip.

Die bekannten Bedienblenden haben jedoch den Nachteil, dass die Tasten stets zu sehen und fĆ¼r den Benutzer zur BetƤtigung bereit stehen. Sind bei einem ausgewƤhlten Programm bestimmte Unterfunktionen oder Parametereinstellungen nicht mƶglich, so kann dies der Benutzer hƤufig nicht eindeutig feststellen oder er muss einer optischen BenutzerfĆ¼hrung folgen.However, the known control panels have the disadvantage that the keys are always visible and ready for the user to operate. If certain subfunctions or parameter settings are not possible with a selected program, then the user can often not clearly determine this or he must follow an optical user guidance.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Bedieneinrichtung mit Tasten oder SchaltflƤchen fĆ¼r ein HaushaltgerƤt bereit zu stellen, das sehr einfach und zu bedienen ist.The invention is therefore based on the object to provide an operating device with buttons or buttons for a household appliance, which is very simple and easy to use.

ErfindungsgemƤƟ wird diese Aufgabe durch eine Bedienblende mit den Merkmalen des unabhƤngigen Anspruchs 1 und durch ein HaushaltgerƤt gemƤƟ Anspruch 18 gelƶst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den jeweils nachfolgenden abhƤngigen AnsprĆ¼chen.This object is achieved by a control panel having the features of independent claim 1 and by a household appliance according to claim 18. Advantageous embodiments and modifications of the invention will become apparent from the respective following dependent claims.

Die mit der Erfindung erreichbaren Vorteile bestehen darin, dass die Bedienungseinrichtung ein Ć¼bersichtliches und aufgerƤumtes Blendenteil aufweist, das jedoch eine Vielzahl von Bedieneinstellungen oder Parametereinstellungen bietet. Die Ɯbersichtlichkeit wird dadurch erreicht, dass nur die Tasten oder BerĆ¼hrflƤchen fĆ¼r den Benutzer sicht- und tastbar sind, die fĆ¼r den jeweils vorzunehmenden Bedienschritt zur Auswahl stehen. Nicht anwƤhlbare FlƤchen oder Tasten sind dann auf der Blende nicht zu bemerken oder zu sehen, sie werden dem Bediener nicht angeboten. Diese Eigenschaft der Bedieneinrichtung wird dadurch erreicht, dass die Blende mit der Folie auƟenseitig im wesentlichen eben ausgebildet ist, wobei die Bedieneirichtung dazu ausgebildet ist, jeweils zur BetƤtigung geeignete Tasten oder Bedienbereiche bedarfsweise als aus der Ebene sicht- und tastbar zu erheben.The achievable with the invention advantages are that the operating device has a clear and tidy screen part, but offers a variety of operating settings or parameter settings. The clarity is achieved in that only the buttons or touch surfaces are visible and palpable for the user, which are available for the respective operating step to be selected. Non-selectable areas or buttons are then not noticeable or visible on the screen, they are not offered to the operator. This feature of the operating device is achieved in that the diaphragm is formed with the film on the outside substantially flat, wherein the Bedieneirichtung is adapted to each of the operation suitable buttons or operating areas as needed from the plane visible and palpable to lift.

In einer zweckmƤƟigen AusfĆ¼hrung ist die Folie dehnbar und flexibel, also biegbar, ausgebildet. Dadurch ist sichergestellt, dass die Blende eine ebene FlƤche besitzt, wenn keine Taste zur BetƤtigung erhaben ausgebildet ist. Ferner ist sichergestellt, dass bei der ZurĆ¼cknahme des erhabenen Tastenbereichs die Taste kurzfristig vollstƤndig verschwindet und sich eine ebene FlƤche auf der Blende einstellt.In an expedient embodiment, the film is stretchable and flexible, ie bendable, formed. This ensures that the panel has a flat surface, if no button is designed for operation raised. It also ensures that when the raised button area is withdrawn, the button completely disappears in the short term and a flat surface is established on the screen.

In einer weiteren AusfĆ¼hrung ist der BetƤtigungsbereich bzw. die die Taste im erhabenen Zustand in etwa pyramidenstumpffƶrmig oder kalottenfƶrmig geformt. Diese Formen sind besonders gut zu erkennen und zu ertasten. Ferner kƶnnen derartige Formen besonders gut aus der Folie herausgebildet werden, ohne sie nach mehrmaliger BetƤtigung zu beschƤdigen oder zu verschleiƟen.In a further embodiment, the actuating region or the button in the raised state in approximately truncated pyramid or dome shaped. These forms are particularly easy to recognize and to feel. Furthermore, such shapes can be formed out of the film particularly well without damaging or wearing them after repeated actuation.

In einer vorteilhaften AusfĆ¼hrung ist der BetƤtigungsbereich bzw. die die Taste im nicht erhabenen Zustand zumindest im Wesentlichen eben bzw. eben mit der Blende ausgebildet. Wie bereits oben geschildert, werden dadurch dem Bediener weniger Tasten oder BedienflƤchen angeboten, als insgesamt auf der Blende vorhanden sind, wodurch eine Ć¼bersichtliche und aufgerƤumte Blende bereitgestellt wird.In an advantageous embodiment, the actuating region or the button in the non-raised state is formed at least substantially evenly or even with the diaphragm. As already described above, the operator is offered fewer keys or control surfaces than are present overall on the screen, whereby a clear and tidy screen is provided.

In einer weiteren AusfĆ¼hrung umfasst der FlƤchenbereich zwischen zumindest zwei benachbarten erhabenen Tastenbereichen einen Stegbereich, welcher dazu ausgebildet ist, sich bedarfsweise zu erheben. Dadurch wird eine BenutzerfĆ¼hrung erreicht, die durch Ertasten der BedienflƤche bereitgestellt wird. So kann ein sehbehinderter Benutzer oder im Dunkeln durch Ertasten die zu betƤtigenden Tasten sicher erkannt und bedarfsweise betƤtigt werden.In a further embodiment, the surface area between at least two adjacent raised key areas comprises a land area, which is designed to rise as needed. Thereby, a user guidance is achieved, which is provided by palpation of the control surface. Thus, a visually impaired user or in the dark by groping the keys to be operated safely detected and operated as needed.

Insgesamt ist es zweckmƤƟig, dass die Bedieneinrichtung unterhalb der Folie im Inneren der Bedieneinrichtung im Tastenbereich oder Stegbereich Mittel umfasst, die dazu geeignet sind, aufgrund einer Ansteuerung sich hinsichtlich der Form zu verƤndern und dadurch eine partielle Erhebung auf der AuƟenseite der Folie zu bewirken. Als Mittel zum Bewirken der Erhebung auf der AuƟenseite der Folie dient in einer AusfĆ¼hrung der Erfindung eine formverƤnderbare Blase oder ein Schlauch aus dehnbaren Material, wie Latex oder Ƥhnliches, die/ der bedarfsweise mit einem Fluid, wie FlĆ¼ssigkeit oder Druckluft, gefĆ¼llt werden kann. Das Fluid wird hierbei mittels einer Pumpe und einem Leitungssystem bedarfsweise den Blasen oder SchlƤuchen zugefĆ¼hrt, um eine Erhebung des jeweils zugeordneten Tastenbereichs oder TastenflƤche zu bewirken. Sobald die Taste wieder deaktiviert werden soll, wird der Druck oder das Fluid aus der Blase oder dem Schlauch wieder abgelassen, sodass sich die Folie wieder in die ebene Ausgangsposition zurĆ¼ck verformen kann. Insgesamt wird durch die bedarfsweise Hervorhebung der einzelnen BedienflƤchen eine aufgerƤumte Bedienblende bereitgestellt.Overall, it is expedient that the operating device below the film in the interior of the operating device in the key area or land area comprises means which are adapted to change due to a control with respect to the shape and thereby cause a partial elevation on the outside of the film. As a means for effecting the elevation on the outside of the film, in one embodiment of the invention, a deformable bladder or tube of stretchable material, such as latex or the like, may be filled as required with a fluid, such as liquid or compressed air. The fluid is supplied by means of a pump and a line system, if necessary, the bubbles or hoses to effect a survey of each associated key area or key area. Once the button is to be deactivated again, the pressure or fluid from the bladder or hose is released again, so that the film can deform back into the flat starting position. Overall, a tidy control panel is provided by the need for emphasis on the individual control surfaces.

In einer anderen AusfĆ¼hrung umfasst die Bedieneinrichtung unterhalb der Folie im Tastenbereich oder Stegbereich Mittel, die dazu geeignet sind, aufgrund einer Ansteuerung eine Bewegung auf die Folie auszuĆ¼ben und dadurch eine partielle Erhebung auf der AuƟenseite der Folie zu bewirken. Hierbei kommt vorzugsweise ein elektromagnetisches Schaltelement zum Einsatz, das bedarfsweise zur AusfĆ¼hrung einer Bewegung zur partiellen Erhebung der jeweiligen SchaltflƤche aktiviert werden kann.In another embodiment, the operating device below the film in the key area or web area comprises means which are suitable for exerting a movement on the film on the basis of an activation and thereby effecting a partial elevation on the outside of the film. In this case, preferably an electromagnetic switching element is used, which can be activated as needed to perform a movement for partial collection of the respective button.

ZweckmƤƟigerweise umfasst die Bedieneinrichtung unterhalb der Folie im Tastenbereich oder Stegbereich Mittel, die dazu geeignet sind, aufgrund einer Ansteuerung sich hinsichtlich der Form zu verƤndern und dadurch eine partielle Erhebung auf der AuƟenseite der Folie zu bewirken. Als Mittel zum Bewirken der Erhebung auf der AuƟenseite der Folie dient in einer bevorzugten AusfĆ¼hrung eine formverƤnderbare Blase oder Schlauch, der bedarfsweise mit einem Fluid, wie FlĆ¼ssigkeit oder Druckluft, gefĆ¼llt werden kann. Diese Anordnung kann auf einfache Weise mit einem Drucklufterzeuger und eine Ventilanordnung bereitgestellt werden, wobei mit den Ventilen die Druckluft zu den einzelnen Erhebungsbereichen gefĆ¼hrt bzw. durchgelassen werden kann. Die Ventile und der Drucklufterzeuger oder Druckfluiderzeuger werden vorzugsweise von einer Steuereinrichtung angesteuert.Expediently, the operating device below the film in the key area or land area comprises means which are suitable for changing shape with respect to activation and thereby effecting a partial elevation on the outside of the film. As a means for effecting the survey on the outside of the film is used in a preferred embodiment, a shape-changeable bladder or hose, which can if necessary be filled with a fluid such as liquid or compressed air. This arrangement can be provided in a simple manner with a compressed air generator and a valve arrangement, with the valves, the compressed air can be passed to the individual survey areas or let through. The valves and the compressed air generator or pressure fluid generator are preferably controlled by a control device.

In einer vorteilhaften Weiterbildung sind die Mittel zum Bewirken der partielle Erhebung auf der AuƟenseite der Folie auch fĆ¼r die Sensierung der TastenbetƤtigung ausgebildet. Somit muss fĆ¼r eine SchaltflƤche nur ein einziges aktives Mittel unterhalb der Folie angeordnet werden, das sowohl die FormverƤnderung bewirkt und gleichzeitig dire Funktion des Schalters oder Tasters selbst Ć¼bernimmt.In an advantageous development, the means for effecting the partial elevation on the outside of the film are also designed for the sensing of the key operation. Thus, for a button, only a single active means must be placed below the slide, which effects both the change in shape and at the same time takes over the direct function of the switch or button itself.

In einer anderen, vorteilhaften AusfĆ¼hrung dient als Mittel zum Bewirken der Erhebung auf der AuƟenseite der Folie ein formverƤnderbares Piezoelektrisches Element, das bedarfsweise mit einer elektrischen Spannung beaufschlagt werden kann. Die Ansteuerung durch eine elektrische Kontaktierung oder Leitung ist besonders einfach und zuverlƤssig auszubilden. Die Ansteuerung kann hierbei direkt durch die Steuereinrichtung bzw. durch einen Mikrocontroller der Steuereinrichtung erfolgen.In another advantageous embodiment serves as a means for effecting the survey on the outside of the film, a shape-variable piezoelectric element, which can be applied, if necessary, with an electrical voltage. The control by an electrical contact or line is particularly simple and reliable form. The control can be done directly by the controller or by a microcontroller of the controller.

In einer zweckmƤƟigen AusfĆ¼hrung ist / sind das Schaltelement oder die Schaltelemente in den Wirkbereich der formverƤnderbaren Mittel angeordnet. Dadurch ist sichergestellt, dass dem Benutzer nur die durch FormverƤnderung angebotenen SchaltflƤchen sicher die Schaltfunktion bereitstellen. BerĆ¼hrungen oder DruckbetƤtigungen auf den benachbarten Bereichen fĆ¼hren dann nicht zu FehlbetƤtigungen.In an expedient embodiment, the switching element or the switching elements is / are arranged in the effective range of the shape-changing means. This ensures that only the buttons offered by the change in shape reliably provide the switching function to the user. Touching or pressure actuation on the adjacent areas then do not lead to incorrect operations.

In einer vorteilhaften Weiterbildung ist das piezoelektrische Element auch fĆ¼r die Sensierung einer TastenbetƤtigung ausgebildet. Damit ist kein weiteres elektrisches Bauelement zur Bereitstellung der Tastenfunktion mehr notwendig.In an advantageous development, the piezoelectric element is also designed for the sensing of a key operation. Thus, no further electrical component for providing the key function is more necessary.

In einer anderen vorteilhaften AusfĆ¼hrung ist als Mittel zum Bewirken der Erhebung auf der AuƟenseite der Folie eine formverƤnderbare, sogenannte artifical muscle Folie eingesetzt. In diese Folien ist eine Schicht- oder Faserstruktur aus elektroaktiven Kunststoffmaterial, wie Polymer, eingebunden, um eine Muskelfunktion eines Lebewesens nachzuempfinden. Durch Anlegen von elektrischen Spannungen oder partiellen ErwƤrmungen wird die vorgesehene FormverƤnderung zur Aufbeulung der aktivierten TastenflƤche verursacht.In another advantageous embodiment, a form-variable, so-called artifical muscle film is used as a means for effecting the survey on the outside of the film. In these films, a layer or fiber structure of electroactive plastic material, such as polymer, integrated to mimic a muscle function of a living being. By applying electrical voltages or partial heating, the intended change in shape causes the activated key surface to bulge.

In einer umfasst die Bedieneinrichtung eine Steuereinrichtung, die dazu eingerichtet ist, die Erhebung einer BedienflƤche oder mehrerer BedienflƤchen abhƤngig einer vorangegangenen Bedienung vorzunehmen. Somit kann eine BenutzerfĆ¼hrung auf einer einfach und Ć¼bersichtlich anmutenden Bedienblende ohne Display erreicht werden.In one, the operating device comprises a control device, which is set up to carry out the survey of a control surface or a plurality of control surfaces depending on a previous operation. Thus, user guidance can be achieved on a simple and clear control panel without display.

Hierbei ist es zweckmƤƟig, dass die temporƤr nicht zu betƤtigenden BedienflƤchen nicht erhaben in der Ebene der Folie verbleiben. Somit wird dem Benutzer nur eine kleine Auswahl von Tasten zur BetƤtigung angeboten. Die Bedienblende wird dadurch nicht durch eine Vielzahl von Tasten oder sichtbaren SchaltflƤchen Ć¼berfrachtet.It is expedient that the temporary not operable control surfaces do not remain sublime in the plane of the film. Thus, the user is offered only a small selection of keys for actuation. The control panel is not overburdened by a variety of buttons or visible buttons.

In einer insgesamt vorteilhaften Weiterbildung sind die zur BetƤtigung geeigneten Tasten oder Bedienbereiche mit jeweils einer diesen FlƤchen zugeordneten Beschriftung versehen, sobald die Tasten oder Bedienbereiche zur BetƤtigung angeboten werden. Damit wird zusƤtzlich zum taktilen Mittel, wie es die erhabene, vom Benutzer zu ertastende SchaltflƤche darstellt, eine optisches Mittel zur entsprechenden SchaltflƤche kombiniert. Die jeweiligen Tasten oder SchaltflƤchen bestehen hierbei jeweils aus einem opto-taktilen Mittel.In an overall advantageous development, the buttons or operating areas suitable for actuation are each provided with a label associated with these areas as soon as the buttons or operating areas are offered for actuation. Thus, in addition to the tactile means, such as the sublime, user-to-touch button, one optical means combined to the corresponding button. The respective buttons or buttons in this case each consist of an opto-tactile means.

In Fig. 1 ist eine Bedieneinrichtung 2 in der Front eines HaushaltgerƤtes 1, in diesem Beispiel eine WƤschebehandlungsmaschine, aufskizziert. FĆ¼r den Bediener ist die sichtbare Seite des Blendenteils 3 mit den darin angeordneten Tasten 4, 4a (Fig. 2 bis 5) zur Auswahl von Programmen und/oder Programmparametern zugƤnglich. In diesem Beispiel ist das Blendenteil 3 schrƤg bzw. in einem Winkel im Bereich von 10 bis 50 Ā° geneigt angeordnet, so dass eine BetƤtigung der Tasten 4 von schrƤg vorn erfolgt. Bei vertikal oder im Wesentlichen horizontal angeordneten Blendenteilen erfolgt die BetƤtigung entsprechend von vorn bzw. von oben. Auf der Bedienblende 3 ist die SchaltflƤche oder Taster 4a zum Einschalten des GerƤtes dauerhaft sichtbar und/oder taktil, also als Erhebung, ausgebildet.In Fig. 1 is an operating device 2 in the front of a household appliance 1, in this example a laundry treatment machine, sketched. For the operator, the visible side of the panel part 3 with the keys 4, 4a (FIG. Fig. 2 to 5 ) for selecting programs and / or program parameters. In this example, the panel part 3 is inclined or inclined at an angle in the range of 10 to 50 Ā°, so that an actuation of the keys 4 takes place obliquely from the front. In the case of vertically or substantially horizontally arranged panel parts, the actuation takes place correspondingly from the front or from above. On the control panel 3, the button or button 4a to turn on the device permanently visible and / or tactile, so as survey, trained.

In Fig. 2 ist die Situation der Bedienblende 3 bzw. der sichtbaren Seite im ausgeschalteten Zustand skizziert. Hier ist nur die SchaltflƤche 4a des Ein-und Ausschalters sichtbar oder tastbar. Beim BetƤtigen dieser Taste 4a werden die SchaltflƤchen oder Tasten fĆ¼r die Programmeinstellung hervorgehoben, hier 4bk fĆ¼r Koch-BuntwƤsche, 4bp fĆ¼r ein Pflegeleichtprogramm, 4bf fĆ¼r ein FeinwƤscheprogramm und 4bw fĆ¼r Wollwaschprogramm. hervorgehoben, wie dies in Fig. 3 skizziert ist. Beispielhaft wird die hervorgehobene Taste 4bk mit dem Finger 5 des Benutzers gedrĆ¼ckt oder berĆ¼hrt. Danach, wie in Fig. 4 dargestellt, verbleibt nur die aktivierte Taste 4bk hervorgehoben, die anderen Tasten 4bp, 4bf, 4bw verschwinden wieder bzw. die SchaltflƤchen auf dem Blendenteil ebnen sich wieder. Die weiteren Tasten fĆ¼r die Temperatureinstellung oder anderen Zusatzeinstellungen werden hervorgehoben, hier die Taste 4c30 fĆ¼r 30Ā° Laugentemperatur, 4c40 fĆ¼r 40Ā°, 4c60 fĆ¼r 60 und 4c95 fĆ¼r 95Ā° Laugentemperatur. In Fig. 5 ist dargestellt, dass der Benutzer mit seinem Finger 5 die Taste 4c30 betƤtigt, um die Option fĆ¼r 30Ā° Laugentemperatur einzustellen. Danach verschwinden die nicht betƤtigten Hervorhebungen 4s40, 4c60 und 4c95, wie in Fig. 6 dargestellt. Dadurch, dass die Hervorhebung der nicht betƤtigten SchaltflƤchen wieder zurĆ¼ckgenommen wird, verschwinden diese aus dem Sicht- und Tastbereich des Benutzers, sodass die vorgenommene Einstellung fĆ¼r den Benutzer sichtbar und tastbar bleibt. Insgesamt ist und bleibt das Blendenteil 3 wƤhrend der Bedienung und danach aufgerƤumt, da im normalen Betrieb alle SchaltflƤchen oder Taster gleichzeitig sichtbar oder rƤumlich hervorgehoben sind. Eine verwirrende Schaltervielfalt ist somit auf dem Blendenteil 3 nicht vorhanden. In Fig. 3 bis 5 ist ferner zu erkennen, dass die hervorgehobenen Tasten 4a, 4bk, 4bp, 4bf, 4bw, 4c30, 4c40, 4c60, 4c95 mit einem Symbol oder einem Text 16 beschriftet sind. Die Beschriftung ist in dieser AusfĆ¼hrung nur fĆ¼r die hervorgehobenen Tasten 4a, 4bk, 4bp, 4bf, 4bw, 4c30, 4c40, 4c60, 4c95 aktiviert. Die Beschriftung 16 befindet sich hier jeweils neben den Tasten 4bk, 4bp, 4bf, 4bw, 4c30, 4c40, 4c60, 4c95, sie kann sich jedoch auf den Tasten oder SchaltflƤchen 4a selbst befinden. Als Beschriftung 16 kƶnnen Leuchtanzeigen oder Displays verwendet werden.In Fig. 2 the situation of the control panel 3 or the visible side is sketched in the off state. Here only the button 4a of the on-off switch is visible or palpable. Pressing this button 4a highlights the buttons or buttons for program setting, here 4bk for cooking color, 4bp for a light-care program, 4bf for a fine-laundry program and 4bw for wool-washing program. highlighted as this in Fig. 3 outlined. By way of example, the highlighted key 4bk is pressed or touched with the user's finger 5. After that, as in Fig. 4 shown, only the activated key 4bk remains highlighted, the other keys 4bp, 4bf, 4bw disappear again or the buttons on the panel part level again. The other keys for temperature setting or other additional settings are highlighted, here the key 4c30 for 30 Ā° liquor temperature, 4c40 for 40 Ā°, 4c60 for 60 and 4c95 for 95 Ā° liquor temperature. In Fig. 5 It is shown that the user presses his finger 5 button 4c30 to set the option for 30 Ā° lye temperature. Thereafter, the non-emphasized highlights 4s40, 4c60 and 4c95 disappear as in Fig. 6 shown. The fact that the highlighting of the non-actuated buttons is withdrawn, these disappear from the visual and tactile area of the user, so that the setting made remains visible and palpable to the user. Overall, the panel part 3 is and remains tidy during operation and then, as in normal operation all buttons or buttons are simultaneously visible or spatially highlighted. A confusing variety of switches is thus not present on the panel part 3. In Fig. 3 to 5 It will also be appreciated that the highlighted keys 4a, 4bk, 4bp, 4bf, 4bw, 4c30, 4c40, 4c60, 4c95 are labeled with a symbol or text 16. The label is activated in this embodiment only for the highlighted keys 4a, 4bk, 4bp, 4bf, 4bw, 4c30, 4c40, 4c60, 4c95. The label 16 is here in each case next to the buttons 4bk, 4bp, 4bf, 4bw, 4c30, 4c40, 4c60, 4c95, but they can be located on the buttons or buttons 4a itself. As a label 16 lights or displays can be used.

In einer AusfĆ¼hrung gemƤƟ Fig. 6 sind zwischen den SchaltflƤchen bedarfsweise zusƤtzlich erhabene Stegbereiche 9 vorhanden, die den Benutzer eine taktile Orientierung zu den nachfolgend zu betƤtigenden Tastern oder BedienflƤchen bietet.In an embodiment according to Fig. 6 If required, additional raised web areas 9 are present between the buttons as required, offering the user a tactile orientation to the buttons or control surfaces to be subsequently actuated.

Fig. 7 zeigt die Bedieneinrichtung 2 in einer skizzierten Schnittdarstellung. Die Blende 3 umfasst auƟenseitig eine Folie 10, die auf einem TrƤger 3a der Blende 3 angebracht bzw. aufgeklebt ist. In dem TrƤger 3a befinden sich Aushƶhlungen 11, in die Mittel 12 zum Bewirken einer partiellen Erhebung 15 (Fig. 8). Die Mittel 12 sind signaltechnisch oder elektrisch mittels Verbindungsleitungen 14 mit einer Steuereinrichtung 13 verbunden, die einerseits die Aktivierung der SchaltflƤche 4 durch Hervorheben bewirkt und andererseits die Sensierung der BetƤtigung vornehmen kann. Fig. 8 zeigt beispielhaft, dass das Mittel 12 zum Bewirken einer partiellen Erhebung 14 durch die Steuereinrichtung 13 aktiviert sind, um die SchaltflƤchen 4 hervorzuheben und einen sichtbaren Schalter 4 auf der Blende 3 bereitzustellen. Die Folie 10 ist dabei dehnbar, sodass sich die Folie 10 bei ZurĆ¼cknahme der Vorhebung in die ebene Ausgangslage oder Form zurĆ¼ck verformt. Die Folie 10 ist fĆ¼r eine Vielzahl dieser, dieser Bewegungen ausgebildet, sodass nach mehrmaliger Benutzung keine remanente Verformung in der Folie 10 verbleibt. Als Mittel 12 fĆ¼r die partielle Erhƶhung ist in diesem Beispiel ein piezoelektrische Mittel vorgesehen, das mittels einer elektrischen Spannung die Form verƤndern kann. Die Sensierung kann durch eine Messung der elektrischen Eigenschaften des piezoelektrischen Elements vorgenommen werden, wobei hier der Effekt ausgenutzt wird, dass sich die elektrischen Eigenschaften des piezoelektrischen Elements bei Druckbeaufschlagung, also bei BetƤtigung) verƤndern. Fig. 7 shows the operating device 2 in a sketched sectional view. The panel 3 comprises on the outside a film 10 which is mounted or glued on a support 3a of the panel 3. In the support 3a are cavities 11, in the means 12 for effecting a partial elevation 15 (FIG. Fig. 8 ). The means 12 are signal or electrically connected by means of connecting lines 14 with a control device 13, on the one hand causes the activation of the button 4 by highlighting and on the other hand can make the sensing of the operation. Fig. 8 2 shows by way of example that the means 12 for effecting a partial elevation 14 are activated by the control device 13 in order to emphasize the buttons 4 and to provide a visible switch 4 on the diaphragm 3. The film 10 is stretchable, so that the film 10 is deformed back upon withdrawal of the highlighting in the flat starting position or shape. The film 10 is designed for a multiplicity of these movements, so that after repeated use no remanent deformation remains in the film 10. As means 12 for the partial increase in this example, a piezoelectric means is provided which can change the shape by means of an electrical voltage. The sensing can be done by measuring the electrical properties of the piezoelectric element, in which case the effect is exploited that change the electrical properties of the piezoelectric element when pressurized, ie when actuated).
