Description

Die vorliegende Erfindung betrifft ein Haushaltsgerät.The present invention relates to a household appliance.

Haushaltsgeräte wie beispielsweise Backöfen verfügen über Anzeigen und Bedienelemente, über welche der Benutzer Einstellungen am Gerät vornehmen kann und über welche er eine Rückmeldung über die getätigten Einstellungen oder bereits eingestellte Parameter wie zum Beispiel Heizart, Dauer, Temperatur und dergleichen erhält. In der Regel werden Versenknebel, Knebel, Tasten oder ähnlich ausgeformte Bedienelemente, bei denen der Anzeigenbereich räumlich neben den Werteverstellern liegt, verwendet. Die DE 195 04 471 A1 beschreibt ein derartiges Bedienelement in Form eines Drehknebels.Domestic appliances such as ovens have displays and controls over which the user can make settings on the device and through which he receives feedback on the settings made or already set parameters such as type of heating, duration, temperature and the like. As a rule, countersunk nebulas, toggles, buttons or similarly shaped controls, where the display area is located next to the value adjusters, are used. The DE 195 04 471 A1 describes such an operating element in the form of a rotary knob.

Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung, ein verbessertes Haushaltsgerät zur Verfügung zu stellen.Against this background, an object of the present invention is to provide an improved household appliance.

Demgemäß wird ein Haushaltsgerät mit einer Bedienblende und einem plattenförmigen Bedienelement zum Betätigen einer Steuereinrichtung des Haushaltsgeräts vorgeschlagen, wobei das plattenförmige Bedienelement mit Hilfe von Schnapphaken an der Bedienblende befestigt ist und wobei das plattenförmige Bedienelement zum Betätigen der Steuereinrichtung in mehrere unterschiedliche Positionen relativ zu der Bedienblende verkippbar ist.Accordingly, a domestic appliance with a control panel and a plate-shaped operating element for actuating a control device of the household appliance is proposed, wherein the plate-shaped control element is attached by means of snap hooks on the control panel and wherein the plate-shaped control element for actuating the control device in several different positions tilted relative to the control panel is.

Insbesondere wird das plattenförmige Bedienelement in die Bedienblende mit Hilfe der Schnapphaken eingeschnappt. Dabei verformen sich die Schnapphaken am plattenförmigen Bedienelement vorzugsweise elastisch und verhaken sich in entsprechenden Durchbrüchen der Bedienblende. Ein Bediener ist dadurch vor spannungsführenden Teilen oder Fehlgebrauch geschützt. Vom Geräteinneren ist die Schnappverbindung lösbar, beispielsweise für Reparaturen. Mit Hilfe der Schnapphaken und zusätzlichen Abstimmrippen sitzt das Bedienelement nahezu spielfrei in der Bedienblende. Die Bedienblende kann auch als Bedienfront bezeichnet werden. Das plattenförmige Bedienelement kann in die Bedienblende eingelassen sein. Hierzu kann an der Bedienblende eine taschenförmige Ausnehmung vorgesehen sein, wodurch das plattenförmige Bedienelement in der Bedienblende eingebettet wird. Die Bedienblende kann hierdurch leichter mit einem Tuch gereinigt werden. Vorzugsweise ist das plattenförmige Bedienelement in vier unterschiedliche Positionen relativ zu der Bedienblende verkippbar.In particular, the plate-shaped control element is snapped into the control panel using the snap hook. In this case, the snap hooks on the plate-shaped operating element deform preferably elastically and get caught in corresponding apertures of the control panel. This protects an operator from live parts or misuse. From the inside of the device, the snap connection is solvable, for example for repairs. With the help of snap hooks and additional tuning ribs, the control element sits almost free of play in the control panel. The control panel can also be referred to as the front panel. The plate-shaped control element can be embedded in the control panel. For this purpose, a pocket-shaped recess may be provided on the control panel, whereby the plate-shaped control element is embedded in the control panel. The control panel can be lighter with a cloth getting cleaned. Preferably, the plate-shaped control element is tiltable in four different positions relative to the control panel.

Das Haushaltsgerät 1 weist eine Bedienblende 5 auf. Die Bedienblende 5 ist plattenförmig und kann oberhalb der Tür 3 angeordnet sein. Das Haushaltsgerät 1 weist weiterhin ein plattenförmiges Bedienelement 6 auf, das dazu eingerichtet ist, eine Steuereinrichtung des Haushaltsgeräts 1 zu betätigen. Das plattenförmige Bedienelement 6 kann in die Bedienblende 5 eingelassen sein. Hierzu kann an der Bedienblende 5 eine taschenförmige Ausnehmung vorgesehen sein, wodurch das plattenförmige Bedienelement 6 in der Bedienblende 5 eingebettet wird. Die Bedienblende 5 kann hierdurch leichter mit einem Tuch gereinigt werden. Insbesondere kann das plattenförmige Bedienelement 6 in einem Initialzustand bündig mit der Bedienblende 5 ausgerichtet sein. Alternativ kann das plattenförmige Bedienelement 6 in dem Initialzustand über die Bedienblende 5 herausragen. Unter dem "Initialzustand" ist ein Zustand zu verstehen, in dem ein Benutzer das plattenförmige Bedienelement 6 nicht betätigt. Beispielsweise kann das plattenförmige Bedienelement 6 mit Hilfe einer Federvorspannung in den Initialzustand verbracht werden. Das plattenförmige Bedienelement 6 ist vorzugsweise materialeinstückig. Insbesondere kann das plattenförmige Bedienelement 6 ein Zweikomponentenspritzgussbauteil sein.The household appliance 1 has a control panel 5. The control panel 5 is plate-shaped and can be arranged above the door 3. The household appliance 1 also has a plate-shaped operating element 6, which is set up to actuate a control device of the household appliance 1. The plate-shaped control element 6 can be embedded in the control panel 5. For this purpose, a pocket-shaped recess may be provided on the control panel 5, whereby the plate-shaped control element 6 is embedded in the control panel 5. The control panel 5 can thereby be easily cleaned with a cloth. In particular, the plate-shaped operating element 6 can be aligned flush with the control panel 5 in an initial state. Alternatively, the plate-shaped operating element 6 protrude in the initial state on the control panel 5. The "initial state" is a state in which a user does not operate the plate-shaped operating element 6. For example, the plate-shaped control element 6 can be moved by means of a spring bias in the initial state. The plate-shaped control element 6 is preferably made of one piece of material. In particular, the plate-shaped operating element 6 may be a two-component injection-molded component.

Die Fig. 2 zeigt die Bedienblende 5 mit dem plattenförmigen Bedienelement 6 in einer vergrößerten schematischen Ansicht. Die Fig. 3 zeigt die Bedienblende 5 mit dem plattenförmigen Bedienelement 6 in einer schematischen Vorderansicht. Die Fig. 4 bzw. 5 zeigen jeweils eine schematische Schnittansicht entlang einer Schnittlinie IV-IV bzw. V-V gemäß der Fig. 3. Die Fig. 6 zeigt eine schematische Schnittansicht der Bedienblende 5 entlang der Schnittlinie VI-VI gemäß der Fig. 3. Im Folgenden wird auf die Fig. 2 bis 6 gleichzeitig Bezug genommen.The Fig. 2 shows the control panel 5 with the plate-shaped control element 6 in an enlarged schematic view. The Fig. 3 shows the control panel 5 with the plate-shaped control element 6 in a schematic front view. The Fig. 4 5 respectively show a schematic sectional view along a section line IV-IV or VV according to FIG Fig. 3 , The Fig. 6 shows a schematic sectional view of the control panel 5 along the section line VI-VI according to the Fig. 3 , The following is on the Fig. 2 to 6 simultaneously referred to.

In der Fig. 2 ist ein Koordinatensystem mit einer x-Achse oder x-Richtung x, einer y-Achse oder y-Richtung y und einer z-Achse oder z-Richtung z gezeigt. Das plattenförmige Bedienelement 6 weist Schnapphaken 7, 8 auf. Vorzugsweise sind an dem plattenförmigen Bedienelement 6 zwei Schnapphaken 7, 8 angeordnet. Das plattenförmige und vorzugsweise rechteckige Bedienelement 6 weist weiterhin vier Randabschnitte oder Ecken 9 bis 12 auf. Das plattenförmige Bedienelement 6 kann auch rund oder oval sein. Die Schnapphaken 7, 8 erstrecken sich aus einer Rückseite 13 des plattenförmigen Bedienelements 6 heraus in Richtung der Bedienblende 5. Das plattenförmige Bedienelement 6 ist mit Hilfe der Schnapphaken 7, 8 an der Bedienblende 5 befestigt. Insbesondere sind an der Bedienblende 5 Durchbrüche 14, 15 vorgesehen, in die die Schnapphaken 7, 8 einschnappen. Das plattenförmige Bedienelement 6 wird in die Bedienblende 5 mit Hilfe der Schnapphaken 7, 8 eingeschnappt. Dabei verformen sich die Schnapphaken 7, 8 am plattenförmigen Bedienelement 6 elastisch und verhaken sich in den entsprechenden Durchbrüchen 14, 15 der Bedienblende 5. Ein Benutzer ist dadurch vor spannungsführenden Teilen oder Fehlgebrauch geschützt. Vom Geräteinneren ist die Schnappverbindung lösbar, beispielsweise für Reparaturen. Durch die Schnapphaken 7, 8 und zusätzliche Abstimmrippen sitzt das Bedienelement 6 nahezu spielfrei in der Bedienblende 5.In the Fig. 2 For example, a coordinate system having an x-axis or x-direction x, a y-axis or y-direction y and a z-axis or z-direction z is shown. The plate-shaped control element 6 has snap hooks 7, 8. Preferably, two snap hooks 7, 8 are arranged on the plate-shaped operating element 6. The plate-shaped and preferably rectangular control element 6 also has four edge sections or corners 9 to 12. The plate-shaped control element 6 can also be round or oval. The snap hooks 7, 8 extend from a rear side 13 of the plate-shaped operating element 6 out in the direction of the control panel 5. The plate-shaped control element 6 is fixed by means of the snap hooks 7, 8 on the control panel 5. In particular, 5 breakthroughs 14, 15 are provided on the control panel, in which the snap hooks 7, 8 snap. The plate-shaped control element 6 is snapped into the control panel 5 by means of the snap hooks 7, 8. In this case, the snap hooks 7, 8 deform elastically on the plate-shaped control element 6 and get caught in the corresponding apertures 14, 15 of the control panel 5. A user is thus protected from live parts or misuse. From the inside of the device, the snap connection is solvable, for example for repairs. Through the snap hooks 7, 8 and additional tuning ribs, the control element 6 sits almost free of play in the control panel. 5

Eine Steuereinrichtung 16 des Haushaltsgeräts 1 umfasst eine Platine 17, auf der beispielsweise Schalter 18, 19, 32, insbesondere Mikroschalter, angeordnet sind. Der Schalter 32 kann mittig bezüglich des plattenförmigen Bedienelements 6 positioniert sein. Vorzugsweise sind zwei Schalter 32 vorgesehen. Das plattenförmige Bedienelement 6 ist zum Betätigen der Steuereinrichtung 16 und insbesondere der Schalter 18, 19, 32 in mehrere unterschiedliche Positionen relativ zu der Bedienblende 5 verkippbar. Zum Betätigen der Schalter 18, 19 ist das plattenförmige Bedienelement 6 in einer in der Fig. 2 gezeigten Richtung R1 verkippbar. Zum Betätigen der Schalter 32 ist das plattenförmige Bedienelement 6 in einer in der Fig. 2 gezeigten Richtung R2 verkippbar.A control device 16 of the household appliance 1 comprises a circuit board 17 on which, for example, switches 18, 19, 32, in particular microswitches, are arranged. The switch 32 may be positioned centrally with respect to the plate-shaped operating element 6. Preferably, two switches 32 are provided. The plate-shaped operating element 6 is tiltable for actuating the control device 16 and in particular the switches 18, 19, 32 in a plurality of different positions relative to the control panel 5. For actuating the switches 18, 19, the plate-shaped operating element 6 in a in the Fig. 2 shown direction R1 tiltable. To actuate the switch 32, the plate-shaped operating element 6 in a in the Fig. 2 shown direction R2 tiltable.

Das plattenförmige Bedienelement 6 weist weiterhin Federelemente 20, 21 auf, die zwischen dem plattenförmigen Bedienelement 6 und der Bedienblende 5 angeordnet sind. Vorzugsweise sind vier Federelemente 20, 21 vorgesehen. Jeder Ecke 9 bis 12 kann ein Federelement 20, 21 zugeordnet sein. Die Federelemente 20, 21 sind vorzugsweise als Blattfedern ausgebildet. Insbesondere sind die Federelemente 20, 21 materialeinstückig mit dem plattenförmigen Bedienelement 6 ausgebildet. Die Federelemente 20, 21 sind dazu eingerichtet, das plattenförmige Bedienelement 6 von der Bedienblende 5 wegzudrücken.The plate-shaped control element 6 further comprises spring elements 20, 21, which are arranged between the plate-shaped control element 6 and the control panel 5. Preferably, four spring elements 20, 21 are provided. Each corner 9 to 12 may be associated with a spring element 20, 21. The spring elements 20, 21 are preferably formed as leaf springs. In particular, the spring elements 20, 21 are integrally formed with the plate-shaped control element 6. The spring elements 20, 21 are adapted to push the plate-shaped operating element 6 away from the control panel 5.

Das plattenförmige Bedienelement 6 umfasst Anschlagsabschnitte 22, 23 zum Begrenzen des Wegs des plattenförmigen Bedienelements 6 beim Verkippen desselben. Die Anschlagsabschnitte 22, 23 können als Rippen ausgebildet sein. Hierdurch ist eine leichte und sehr exakte Abstimmung ihrer Größe, Länge und Ebenheit zueinander gegeben. Die Anschlagsabschnitte 22, 23 sind dazu eingerichtet, beim Verkippen des plattenförmigen Bedienelements 6 an Gegenanschlagsabschnitten 24, 25 der Bedienblende 5 anzuliegen. Die Gegenanschlagsabschnitte 24, 25 können rippenförmig sein. In jeder der unterschiedlichen Positionen des plattenförmigen Bedienelements 6 ist jeweils ein Schalter 18, 19, 32 der Steuereinrichtung 16 betätigbar. Durch die Wegbegrenzung mit Hilfe der Anschlagsabschnitte 22, 23 und der Gegenanschlagsabschnitte 24, 25 wird verhindert, dass eine zu hohe Kraft auf die Schalter 18, 19, 32 oder sonstige Bauteile wirken kann. Beschädigungen werden hierdurch vermieden. Insbesondere ist das plattenförmige Bedienelement 6 in vier unterschiedliche Positionen verkippbar.The plate-shaped operating element 6 comprises stop portions 22, 23 for limiting the path of the plate-shaped operating element 6 during tilting thereof. The stopper portions 22, 23 may be formed as ribs. As a result, an easy and very precise vote of their size, length and flatness is given to each other. The Stop sections 22, 23 are adapted to abut when tilting the plate-shaped operating element 6 on counter stop portions 24, 25 of the control panel 5. The counter-abutment portions 24, 25 may be rib-shaped. In each of the different positions of the plate-shaped operating element 6, a respective switch 18, 19, 32 of the control device 16 can be actuated. By limiting the path with the help of the stop portions 22, 23 and the counter-stop portions 24, 25 prevents excessive force on the switches 18, 19, 32 or other components can act. Damage is thereby avoided. In particular, the plate-shaped operating element 6 can be tilted in four different positions.

Jedem Schalter 18, 19 ist ein sich aus einer Rückseite 13 des plattenförmigen Bedienelements 6 heraus erstreckender Bedienstößel 26, 27 zugeordnet. Mit Hilfe der Bedienstößel 26, 27 sind die Schalter 18, 19 betätigbar. Die Schalter 32 sind mit Hilfe von Bedienstößeln 40, 41 (Fig. 7) betätigbar.Each switch 18, 19 is associated with an extending from a rear side 13 of the plate-shaped operating element 6 out operating tappet 26, 27. With the help of the operating tappets 26, 27, the switches 18, 19 can be actuated. The switches 32 are connected by means of operating tappets 40, 41 (FIG. Fig. 7 ) operable.

Auf der Platine 17 sind weiterhin Beleuchtungselemente 28 bis 31 vorgesehen. Die Beleuchtungselemente 28 bis 31 können beispielsweise lichtemittierende Dioden (LED) sein. Das plattenförmige Bedienelement 6 weist Leuchtelemente 33, 34, 39 (Fig. 8) auf, die dazu eingerichtet sind, von den Beleuchtungselementen 28 bis 31 rückseitig beleuchtet zu werden. Die Leuchtelemente 33, 34, 39 können in das plattenförmige Bedienelement 6 eingeklebt sein. Vorzugsweise sind die Leuchtelemente 33, 34, 39 aus einem transparenten Kunststoffmaterial wie zum Beispiel Polymethylmethacrylat (PMMA) gefertigt. Die Leuchtelemente 33, 34, 39 können die Form eines Symbols, beispielsweise eines Pfeils aufweisen.On the board 17 lighting elements 28 to 31 are further provided. The lighting elements 28 to 31 may, for example, be light-emitting diodes (LED). The plate-shaped control element 6 has light-emitting elements 33, 34, 39 (FIG. Fig. 8 ), which are adapted to be backlit by the lighting elements 28 to 31. The lighting elements 33, 34, 39 may be glued into the plate-shaped operating element 6. Preferably, the lighting elements 33, 34, 39 are made of a transparent plastic material such as polymethyl methacrylate (PMMA). The lighting elements 33, 34, 39 may have the shape of a symbol, for example an arrow.

Das plattenförmige Bedienelement 6 weist weiterhin Lichtleitkästen 35 bis 37 (Fig. 7) auf, die dazu eingerichtet sind, das Licht der Beleuchtungselemente 28 bis 31 zu den Leuchtelementen 33, 34, 39 zu leiten. Die Bedienstößel 26, 27, 40, 41 sind in die jeweiligen Lichtleitkästen 35 bis 37 integriert. Hierdurch kann Bauraum eingespart werden. Die Bedienstößel 26, 27, 40, 41 bekommen dadurch auch eine sehr große Eigenstabilität. Die Auflagefläche der Bedienstößel 26, 27, 40, 41 wird zusätzlich vergrößert, um Positionsund Bauteiltoleranzen in x- und z-Richtung auszugleichen und ein sicheres Betätigen zu gewährleisten.The plate-shaped operating element 6 furthermore has light guide boxes 35 to 37 (FIG. Fig. 7 ), which are adapted to guide the light of the lighting elements 28 to 31 to the light-emitting elements 33, 34, 39. The operating tappets 26, 27, 40, 41 are integrated into the respective light guide boxes 35 to 37. As a result, space can be saved. The operating tappets 26, 27, 40, 41 thereby also have a very high intrinsic stability. The contact surface of the operating tappet 26, 27, 40, 41 is additionally enlarged in order to compensate for positional and component tolerances in the x and z directions and to ensure reliable actuation.

Die Fig. 7 zeigt die Rückseite 13 des plattenförmigen Bedienelements 6. Hierbei erstrecken sich die Lichtleitkästen 35 bis 37 aus der Rückseite 13 des plattenförmigen Bedienelements heraus. Die Fig. 6 zeigt das plattenförmige Bedienelement 6 von einer Vorderseite 38 desselben. In die Vorderseite 38 sind die Leuchtelemente 33, 34, 39 eingelassen. Die Leuchtelemente 33, 34, 39 können pfeilförmig ausgebildet sein. Dem Benutzer wird durch eine Markierung wie zum Beispiel einer Bedruckung, Lasermarkierung, Prägung oder in Form von Symbolen, vorzugsweise Pfeilen, signalisiert, in welchem Bereich sich welche Bedienfunktion befindet. Das heißt, drückt er das plattenförmige Bedienelement 6 im oberen Bereich wird der entsprechende Mikroschalter 32 betätigt, der zum Beispiel in einem Menü nach oben scrollt.The Fig. 7 shows the back 13 of the plate-shaped control element 6. Here, the Lichtleitkästen extend 35 to 37 from the back 13 of the plate-shaped control element out. The Fig. 6 shows the plate-shaped control element 6 of a front side 38 thereof. In the front 38, the lighting elements 33, 34, 39 are embedded. The lighting elements 33, 34, 39 may be formed arrow-shaped. The user is signaled by a marking such as a printing, laser marking, embossing or in the form of symbols, preferably arrows, in which area which operating function is located. That is, he presses the plate-shaped control element 6 in the upper region of the corresponding micro-switch 32 is actuated, for example, scrolls up in a menu.

Durch das Betätigen des plattenförmigen Bedienelements 6 entsteht ein Kippen des plattenförmigen Bedienelements 6 in der Bedienblende 5. Ein Drehpunkt, über den das plattenförmige Bedienelement 6 kippt, befindet sich an einer vorderen Kante der Schnapphaken 7, 8 beim Betätigen der Schalter 18, 19 für links/rechts bzw. an der seitlichen Kante des Schnapphakens 7, 8 beim Betätigen der Schalter 32 für oben/unten. Das heißt, die Position des Drehpunktes wird durch die Position und Breite der Schnapphaken 7, 8 beeinflusst. Die Schnapphaken 7, 8 sind so weit außen wie möglich platziert und so breit wie möglich. Durch diese Maßnahme wird der Kippwinkel minimiert und die Schalter 18, 19, 32 auf der Platine 17 werden nahezu linear von den Bedienstößeln 26, 27, 40, 41 getroffen. Zusätzliche Bauteile zur Richtungsumlenkung werden dadurch eingespart. Ein Aufkippen der gegenüberliegenden Seite des plattenförmigen Bedienelements 6 wird dadurch ebenfalls minimiert bzw. verhindert. Ein eventuelles sicherheitsrelevantes Eindringen in die Bedienblende 5 zum Beispiel durch einen Finger wird dadurch verhindert.A pivot point over which the plate-shaped control element 6 tilts is located at a front edge of the snap hooks 7, 8 upon actuation of the switches 18, 19 for the left / right or at the lateral edge of the snap hook 7, 8 when operating the switch 32 for up / down. That is, the position of the fulcrum is influenced by the position and width of the snap hooks 7, 8. The snap hooks 7, 8 are placed as far outboard as possible and as wide as possible. By this measure, the tilt angle is minimized and the switches 18, 19, 32 on the board 17 are almost linearly hit by the operating tappets 26, 27, 40, 41. Additional components for directional deflection are thereby saved. Tilting the opposite side of the plate-shaped operating element 6 is thereby also minimized or prevented. A possible safety-relevant intrusion into the control panel 5, for example by a finger is thereby prevented.

Die Federelemente 20, 21 gewährleisten ein Wiederkehren des plattenförmigen Bedienelements 6 in die Initial- oder Ausgangsstellung und eine stets ebene Platzierung in der Bedienblende 5. Zusätzlich gleichen sie Bauteilungenauigkeiten aus und sorgen für eine präzise und angenehme Haptik. Um Geräusche beim Betätigen zu vermeiden, kann das plattenförmige Bedienelement 6 beispielsweise aus einem gleitfähigem Kunststoff gefertigt werden.The spring elements 20, 21 ensure a recurrence of the plate-shaped operating element 6 in the initial or initial position and always flat placement in the control panel 5. In addition, they compensate for component inaccuracies and ensure a precise and pleasant feel. To avoid noise when operating, the plate-shaped control element 6 can be made for example of a slidable plastic.

Die Beleuchtungselemente 28 bis 31 auf der im Geräteinneren befindlichen Platine 17 strahlen in die Lichtleitkästen 35 bis 37 am plattenförmigen Bedienelement 6. Das Licht wird innerhalb der Lichtleitkästen 35 bis 37 gestreut und ermöglicht eine gleichmäßige Ausleuchtung der Leuchtelemente 33, 34, 39. Dadurch entstehen keine Hotspots und die Beleuchtungselemente 28 bis 31 sind von vorne nicht wahrnehmbar. Um den Effekt zu verstärken, sind die Beleuchtungselemente 28 bis 31 nicht direkt hinter den zu beleuchtenden Leuchtelementen 33, 34, 39 platziert, sondern innerhalb des jeweiligen Lichtleitkastens 35 bis 37 leicht versetzt angeordnet. Die Lichtleitkästen 35 bis 37 ermöglichen die partielle Ausleuchtung ohne Streulicht an unbeleuchteten Stellen der Gerätefront, auch im betätigten Zustand, was ein großer Vorteil gegenüber Lichtleitern darstellt. Die Lichtleitkästen 35 bis 37 können die Bewegung des plattenförmigen Bedienelements 6 bei der Betätigung kompensieren und ermöglichen stets eine gleichmäßige Ausleuchtung.The lighting elements 28 to 31 on the board located inside the board 17 radiate into the Lichtleitkästen 35 to 37 on the plate-shaped control element 6. The light is scattered within the Lichtleitkästen 35 to 37 and allows uniform illumination of the lighting elements 33, 34, 39. This creates no hot spots and the lighting elements 28 to 31 are not noticeable from the front. In order to enhance the effect, the lighting elements 28 to 31 are not placed directly behind the lighting elements 33, 34, 39 to be illuminated, but are arranged slightly offset within the respective light guide box 35 to 37. The Lichtleitkästen 35 to 37 allow partial illumination without stray light at unlit areas of the front of the device, even in the actuated state, which is a great advantage over light guides. The Lichtleitkästen 35 to 37 can compensate for the movement of the plate-shaped operating element 6 during operation and always allow a uniform illumination.

Obwohl die vorliegende Erfindung anhand von Ausführungsbeispielen beschrieben wurde, ist sie vielfältig modifizierbar.Although the present invention has been described with reference to embodiments, it is variously modifiable.
