Unter einem "Ɯberlagerungsbereich" soll insbesondere ein Bereich verstanden werden, der von zumindest zwei, insbesondere benachbart angeordneten Bedienelementen gebildet ist und vorzugsweise zumindest einen Ɯbergangsbereich zwischen den Bedienelementen, die den Ɯberlagerungsbereich ausbilden, ausbildet. Insbesondere ist der Ɯberlagerungsbereich zumindest den Sensorelementen zugeordnet, die den, den Ɯberlagerungsbereich ausbildenden Bedienelementen zugeordnet sind. ZusƤtzlich ist denkbar, dass der Ɯberlagerungsbereich weiteren Sensorelementen zugeordnet ist, beispielsweise einem Zonenwahlsensor, der mittels eines Verbindungselements mit den jeweiligen Bedienelementen verbunden ist. Insbesondere Ć¼bergreifen sich die Bedienelemente in dem Ɯberlagerungsbereich jeweils zumindest teilweise. Unter der Wendung, dass sich die Bedienelemente in dem Ɯberlagerungsbereich jeweils "zumindest teilweise Ć¼bergreifen", soll insbesondere verstanden werden, dass die Bedienelemente in dem Ɯberlagerungsbereich bezĆ¼glich zumindest einer Richtung, die zumindest im Wesentlichen senkrecht zu einer kĆ¼rzesten, die Mittelpunkte und/oder Schwerpunkte zweier bezĆ¼glich der Bedienrichtung benachbart angeordneter Bedienelemente verbindenden Gerade ausgerichtet ist, benachbart angeordnet sind.

In particular, the sensor element is provided to transmit the signal detected when the operating element assigned to the sensor element is actuated at least to the control unit. The phrase that the sensor elements are ā€œassignedā€ to a respective one of the operating elements is to be understood in particular to mean that the sensor elements can be triggered by actuating the respective operating element. In particular, the sensor elements and the respective operating elements assigned to the respective sensor element are arranged in direct contact with one another. The control unit has at least three line elements, one of the line elements being provided to connect one of the control elements to a sensor element of the sensor elements assigned to the control element at least partially, in particular largely, preferably directly. An "overlay area" is to be understood in particular as an area that is formed by at least two, in particular adjacently arranged, control elements and preferably forms at least one transition area between the control elements that form the overlay area. In particular, the overlay area is assigned at least to the sensor elements that are assigned to the operating elements forming the overlay area. In addition, it is conceivable that the overlapping area is assigned to further sensor elements, for example a zone selection sensor, which is connected to the respective operating elements by means of a connecting element. In particular, the operating elements overlap in the overlapping area each at least partially. The phrase that the controls in the overlap area each "at least partially overlap" is to be understood in particular to mean that the controls in the overlap area with respect to at least one direction, which is at least substantially perpendicular to a shortest one, the centers and / or focal points of two is aligned with respect to the operating direction of adjacently arranged operating elements connecting straight lines, are arranged adjacently. ā€œProvidedā€ is to be understood in particular as specifically programmed, designed and / or equipped.

Durch die erfindungsgemƤƟe Ausgestaltung kann insbesondere ein hoher Komfort erreicht werden. Zudem kann vorteilhaft eine groƟe Anzahl verschiedener Befehle bei vorzugsweise einer kleinen Anzahl an Sensorelementen erreicht werden, wodurch eine preiswerte und kompakte HausgerƤtebedienvorrichtung erreicht werden kann. Weiterhin kann vorteilhaft eine effiziente SignalĆ¼bertragung und/oder eine Signalauswertung erreicht werden.The configuration according to the invention can in particular achieve a high level of comfort. In addition, a large number of different commands can advantageously be achieved with preferably a small number of sensor elements, as a result of which an inexpensive and compact domestic appliance control device can be achieved. Furthermore, efficient signal transmission and / or signal evaluation can advantageously be achieved.

Ferner wird vorgeschlagen, dass zumindest eines der Bedienelemente ein weiteres der Bedienelemente in dem Ɯberlagerungsbereich zumindest teilweise umgreift. Unter der Wendung, dass zumindest eines der Bedienelemente ein weiteres der Bedienelemente in dem Ɯberlagerungsbereich zumindest teilweise "umgreift", soll insbesondere verstanden werden, dass zumindest eine Gerade existiert, die in zumindest einer von den Bedienelementen aufgespannten Ebene verlƤuft und die ausgehend von einem Punkt innerhalb des Bedienelements und bei Fortschreiten in Richtung des weiteren Bedienelements zunƤchst das Bedienelement, anschlieƟend zumindest einmal das weitere Bedienelement und bei weiterem Fortschreiten in der Richtung erneut das Bedienelement schneidet. Unter der Wendung, dass zumindest eines der Bedienelemente ein weiteres der Bedienelemente in dem Ɯberlagerungsbereich "zumindest teilweise" umgreift, soll insbesondere verstanden werden, dass eines der Bedienelemente zumindest einen Teilbereich aufweist, der zumindest einen Teilbereich des weiteren der Bedienelemente bezĆ¼glich der Bedienrichtung Ć¼ber einen Winkelbereich von mehr als 90Ā°, insbesondere von mehr als 120Ā° und vorteilhaft von mehr als 180Ā° umgreift. Dadurch kann vorteilhaft in konstruktiv einfacher Weise ein funktionsfƤhiger Ɯberlagerungsbereich erreicht werden.It is further proposed that at least one of the control elements at least partially encompasses another of the control elements in the overlay area. The phrase that at least one of the control elements at least partially "surrounds" another of the control elements in the overlay area is to be understood in particular to mean that there is at least one straight line which runs in at least one plane spanned by the control elements and which starts from a point within of the operating element and when progressing in the direction of the further operating element, first the operating element, then at least once the further operating element and, with further progress in the direction, the operating element again intersects. The phrase that at least one of the control elements "at least partially" encompasses another of the control elements in the overlapping area is to be understood in particular as meaning that one of the control elements has at least a partial area, the at least a partial area of the further control elements over an angular range with respect to the control direction of more than 90 Ā°, in particular of more than 120 Ā° and advantageously encompasses more than 180 Ā°. As a result, a functional overlapping area can advantageously be achieved in a structurally simple manner.

Zudem wird vorgeschlagen, dass die Bedienelemente des jeweiligen Ɯberlagerungsbereichs ineinander greifend angeordnet sind. Unter der Wendung, dass die Bedienelemente des jeweiligen Ɯberlagerungsbereichs "ineinander greifend" angeordnet sind, soll insbesondere verstanden werden, dass zumindest eine Gerade existiert, die in zumindest einer von den Bedienelementen aufgespannten Ebene verlƤuft und die ausgehend von einem Punkt innerhalb eines ersten der Bedienelemente und bei Fortschreiten in Richtung eines zweiten der Bedienelemente zunƤchst das erste Bedienelement, anschlieƟend zumindest einmal das zweite Bedienelement, anschlieƟend zumindest einmal das erste Bedienelement und bei weiterem Fortschreiten in der Richtung erneut das zweite Bedienelement schneidet. Dadurch kann vorteilhaft mittels eines Ineinandergreifens der Bedienelemente eine zielsichere BetƤtigung sowie eine geringe FehleranfƤlligkeit bei einer Auswertung einer BetƤtigung des Ɯberlagerungsbereichs erreicht werden.In addition, it is proposed that the operating elements of the respective overlapping area are arranged so as to interlock. The phrase that the operating elements of the respective overlapping area are arranged "interlocking" should be understood in particular to mean that at least one straight line exists which runs in at least one plane spanned by the operating elements and which, starting from a point within a first of the operating elements and when advancing in the direction of a second of the operating elements, first the first operating element, then at least once the second operating element, then at least once the first operating element and, as the direction progresses, again intersecting the second operating element. As a result, targeted actuation and a low susceptibility to errors when evaluating an actuation of the overlay area can advantageously be achieved by means of interlocking the operating elements.

Weiterhin wird vorgeschlagen, dass die Ɯberlagerungsbereiche jeweils eine LƤnge, insbesondere bezĆ¼glich der Bedienrichtung, von mehr als 10 %, insbesondere von mehr als 15 %, vorteilhaft von mehr als 20 %, einer LƤnge, insbesondere bezĆ¼glich der Bedienrichtung, der Bedienelemente aufweisen. Insbesondere weisen die Ɯberlagerungsbereiche jeweils eine LƤnge, insbesondere bezĆ¼glich der Bedienrichtung, von weniger als 200 %, insbesondere von weniger als 150 % und vorteilhaft von weniger als 100 % einer LƤnge, insbesondere bezĆ¼glich der Bedienrichtung, der Bedienelemente auf. Dadurch kann eine fĆ¼r eine BetƤtigung vorteilhafte LƤnge des Ɯberlagerungsbereichs erreicht werden.It is also proposed that the overlapping areas each have a length, in particular with regard to the operating direction, of more than 10%, in particular more than 15%, advantageously more than 20%, of a length, in particular with regard to the operating direction, of the operating elements. In particular, the overlapping areas each have a length, in particular with regard to the operating direction, of less than 200%, in particular less than 150% and advantageously less than 100% of a length, in particular with regard to the operating direction, of the operating elements. As a result, a length of the overlapping area that is advantageous for actuation can be achieved.

Ferner wird vorgeschlagen, dass die Bedienelemente in einer Reihe angeordnet sind. Unter der Wendung, dass die Bedienelemente in einer "Reihe" angeordnet sind, soll insbesondere verstanden werden, dass die Bedienelemente bezĆ¼glich der Verbindungslinie und/oder der Bedienrichtung benachbart angeordnet sind. Beispielsweise kƶnnte die Verbindungslinie und/oder die Bedienrichtung einen bogenfƶrmigen, kreisfƶrmigen und/oder ebenen Verlauf aufweisen. Alternativ sind weitere, einem Fachmann als sinnvoll erscheinende VerlƤufe der Verbindungslinie und/oder der Bedienrichtung denkbar. Insbesondere bilden die Bedienelemente einen Bedienstreifen, insbesondere einen Bedienslider, aus. Dadurch kƶnnen die Bedienelemente vorteilhaft in einer fĆ¼r einen Bediener angenehmen, bekannten Weise angeordnet werden.It is also proposed that the operating elements are arranged in a row. The phrase that the operating elements are arranged in a ā€œrowā€ should be understood in particular to mean that the operating elements are arranged adjacent to the connecting line and / or the operating direction. For example, the connecting line and / or the operating direction could have an arcuate, circular and / or planar course. Alternatively, further courses of the connecting line and / or the operating direction that appear sensible to a person skilled in the art are conceivable. In particular, the operating elements form an operating strip, in particular an operating slider. As a result, the operating elements can advantageously be arranged in a known manner that is convenient for an operator.

Zudem wird vorgeschlagen, dass die Bedieneinheit zumindest eine Steuereinheit aufweist, die dazu vorgesehen ist, in AbhƤngigkeit von einer BetƤtigungsposition in dem Ɯberlagerungsbereich unterschiedliche Aktionen auszufĆ¼hren. Insbesondere ist die Steuereinheit dazu vorgesehen, in AbhƤngigkeit von einer BetƤtigungsposition in dem Ɯberlagerungsbereich differierende Steuersignale zu erzeugen. Insbesondere ist eine von der Steuereinheit ausgefĆ¼hrte Aktion abhƤngig von zumindest einer prozentualen Ɯberdeckung des Ɯberlagerungsbereichs. Dadurch kann vorteilhaft mittels einer geringen Anzahl an Sensorelementen eine hohe Anzahl an Aktionen erreicht werden, wodurch eine preiswerte HausgerƤtebedienvorrichtung erreicht werden kann.In addition, it is proposed that the operating unit have at least one control unit which is provided to carry out different actions as a function of an actuation position in the overlapping area. In particular, the control unit is provided to generate different control signals as a function of an actuation position in the superimposition area. In particular, an action carried out by the control unit is dependent on at least a percentage coverage of the overlapping area. As a result, a large number of actions can advantageously be achieved by means of a small number of sensor elements, whereby an inexpensive domestic appliance control device can be achieved.

Weiterhin wird vorgeschlagen, dass zumindest die Bedienelemente als Beschichtung ausgebildet sind. Insbesondere ist die Beschichtung aus halbleitendem Material und/oder aus leitendem Material und/oder aus einer Kombination aus halbleitendem und leitendem Material ausgebildet. Insbesondere ist die Beschichtung aus lƶsungsmittelbasierender Tinte ausgebildet, die beispielsweise Anteile an Silber, Kupfer, Aluminium und/oder zumindest einer leitfƤhigen Keramik aufweist. Insbesondere ist eine LeitfƤhigkeit der Beschichtung durch eine Ƅnderung einer Zusammensetzung der Anteile einstellbar. Beispielsweise kƶnnte die Beschichtung durch Besputtern einer groƟen FlƤche und anschlieƟendem Entfernen unerwĆ¼nschter Teilbereiche mittels Laser hergestellt sein. Unter einer "Beschichtung" soll eine insbesondere fest haftende Schicht aus einem Stoff verstanden werden, die auf eine OberflƤche zumindest eines Bauteils aufgebracht ist. Insbesondere weist die Beschichtung eine MaterialstƤrke auf, die weniger als 10 %, vorzugsweise weniger als 5 % und insbesondere weniger als 1 % einer MaterialstƤrke des Bauteils, auf dem die Beschichtung aufgebracht ist, betrƤgt. Insbesondere weist die Beschichtung eine zumindest im Wesentlichen gleich bleibende MaterialstƤrke auf. Insbesondere weist die Beschichtung eine MaterialstƤrke von weniger als 1 mm, insbesondere von weniger als 0,3 mm, vorteilhaft von weniger als 0,1 mm, bevorzugt von weniger als 0,03 mm und vorzugsweise von weniger als 0,01 mm auf. Unter einer "zumindest im Wesentlichen gleich bleibenden MaterialstƤrke" soll insbesondere eine MaterialstƤrke verstanden werden, deren Betrag sich im Bereich der Beschichtung des Bauteils um weniger als 20 %, insbesondere um weniger als 10 % und vorteilhaft um weniger als 5 % Ƥndert. Dadurch kann vorteilhaft eine platzsparende Anordnung zumindest der Bedienelemente erreicht werden.It is also proposed that at least the operating elements are designed as a coating. In particular, the coating is made of semiconducting material and / or of conductive material and / or of a combination of semiconducting and conductive material. In particular, the coating is formed from solvent-based ink which has, for example, proportions of silver, copper, aluminum and / or at least one conductive ceramic. In particular, the conductivity of the coating can be adjusted by changing the composition of the proportions. For example, the coating could be produced by sputtering a large area and then removing undesired partial areas by means of a laser. A ā€œcoatingā€ should be understood to mean an in particular firmly adhering layer made of a substance which is applied to a surface of at least one component. In particular, the coating has a material thickness which is less than 10%, preferably less than 5% and in particular less than 1% of a material thickness of the component to which the coating is applied. In particular, the coating has an at least essentially constant material thickness. In particular, the coating has a material thickness of less than 1 mm, in particular less than 0.3 mm, advantageously less than 0.1 mm, preferably less than 0.03 mm and preferably less than 0.01 mm. An ā€œat least essentially constant material thicknessā€ is to be understood as meaning, in particular, a material thickness whose amount changes in the area of the coating of the component by less than 20%, in particular by less than 10% and advantageously by less than 5%. As a result, a space-saving arrangement of at least the operating elements can advantageously be achieved.

Ferner wird vorgeschlagen, dass die Bedieneinheit berĆ¼hrungsempfindlich ausgebildet ist. Insbesondere ist zumindest eines der Bedienelemente der Bedieneinheit als berĆ¼hrungsempfindliches Bedienelement ausgebildet. Unter einem "berĆ¼hrungsempfindlichen" Bedienelement soll insbesondere ein Bedienelement verstanden werden, das dazu vorgesehen ist, auf eine BerĆ¼hrung und/oder eine AnnƤherung durch einen Bediener, insbesondere eine AnnƤherung eines Kƶrperteils, beispielsweise eines Fingers, eines Bedieners, insbesondere innerhalb eines Abstands von maximal 10 cm, insbesondere maximal 3 cm, vorteilhaft maximal 1 cm, vorzugsweise maximal 0,5 cm zu reagieren. Vorzugsweise reagiert das Bedienelement unabhƤngig von einer direkten BerĆ¼hrung und/oder DruckausĆ¼bung, insbesondere durch eine BerĆ¼hrungsflƤche hindurch auf eine AnnƤherung. Insbesondere ist die BerĆ¼hrungsflƤche als eine Glas- und/oder Kunststoffeinheit und/oder eine Kochfeldplatte ausgebildet. Dadurch kann vorteilhaft die Bedieneinheit in einer fĆ¼r einen Bediener angenehm einfachen Weise bedient werden.It is also proposed that the operating unit be designed to be touch-sensitive. In particular, at least one of the operating elements of the operating unit is designed as a touch-sensitive operating element. A "touch-sensitive" control element is to be understood in particular as a control element which is provided to respond to a touch and / or an approach by an operator, in particular an approach of a body part, for example a finger, of an operator, in particular within a maximum distance of 10 cm, in particular a maximum of 3 cm, advantageously a maximum of 1 cm, preferably a maximum of 0.5 cm. The operating element preferably reacts to an approach independently of direct contact and / or exertion of pressure, in particular through a contact surface. In particular, the contact surface is designed as a glass and / or plastic unit and / or a hob plate. As a result, the operating unit can advantageously be operated in a manner that is pleasantly simple for an operator.

On a side facing away from the row terminating the row with respect to the operating direction 44, the row terminating of the operating elements 14, 16, 18 has a recess which is essentially identical to the recess of the second operating element 16.

FĆ¼r eine weitere Beschreibung einer Anordnung der Bedienelemente 14, 16, 18 werden lediglich drei der Bedienelemente 14, 16, 18 betrachtet, die bezĆ¼glich der Bedienrichtung 44 direkt benachbart angeordnet sind. Das erste und zweite Bedienelement 14, 16 bilden einen ersten Ɯberlagerungsbereich 26 aus und das zweite und dritte Bedienelement 16, 18 bilden einen zweiten Ɯberlagerungsbereich 28 aus. Jeder der Ɯberlagerungsbereiche 26, 28 ist dazu vorgesehen, jeweilige Sensorelemente 20, 22, 24, die den, den Ɯberlagerungsbereich 26, 28 ausbildenden, Bedienelementen 14, 16, 18 zugeordnet sind, auszulƶsen.For a further description of an arrangement of the operating elements 14, 16, 18, only three of the operating elements 14, 16, 18 are considered, which are arranged directly adjacent with respect to the operating direction 44. The first and second operating elements 14, 16 form a first overlay area 26 and the second and third operating elements 16, 18 form a second overlay area 28. Each of the overlay areas 26, 28 is provided for the purpose of triggering respective sensor elements 20, 22, 24 which are assigned to the operating elements 14, 16, 18 forming the overlay area 26, 28.

Im vorliegenden AusfĆ¼hrungsbeispiel umgreift eines der Bedienelemente 14, 16, 18 ein weiteres der Bedienelemente 14, 16, 18 in dem Ɯberlagerungsbereich 26, 28 teilweise. Jedes der Bedienelemente 14, 16, 18 weist eine Auswƶlbung und eine zu der Auswƶlbung korrespondierende Ausnehmung auf, die bezĆ¼glich der Bedienrichtung 44 auf einer der Auswƶlbung gegenĆ¼berliegenden Seite angeordnet ist. Eine Auswƶlbung eines der Bedienelemente 14, 16, 18 ist von einer Ausnehmung eines weiteren der Bedienelemente 14, 16, 18 teilweise umgriffen.In the present exemplary embodiment, one of the operating elements 14, 16, 18 partially engages around another of the operating elements 14, 16, 18 in the overlapping area 26, 28. Each of the operating elements 14, 16, 18 has a bulge and a recess corresponding to the bulge, which is arranged on a side opposite the bulge with respect to the operating direction 44. A bulge of one of the operating elements 14, 16, 18 is partially encompassed by a recess of another of the operating elements 14, 16, 18.

In den Fig. 3 bis 5 sind alternative AusfĆ¼hrungsbeispiele dargestellt. Alternativ ist denkbar, dass sich die Bedienelemente 14, 16, 18 in dem Ɯberlagerungsbereich 26, 28 jeweils teilweise Ć¼bergreifen (vgl. Fig. 3 und Fig. 5). Hierbei kƶnnte ein erstes der Bedienelemente 14, 16, 18 jeweils eine bezĆ¼glich der Bedienrichtung 44 abgeschrƤgte SeitenflƤche aufweisen, die mit einer korrespondierenden abgeschrƤgten SeitenflƤche eines zweiten dem Bedienelement 14, 16, 18 benachbarten Bedienelement 14, 16, 18 Ć¼bergreifend angeordnet sein kƶnnte (vgl. Fig. 5). Ebenfalls denkbar ist, dass die Bedienelemente 14, 16, 18 jeweils versetzt zueinander angeordnete VorsprĆ¼nge aufweisen, die Ć¼bergreifend angeordnet sind (vgl. Fig. 3). Weiterhin denkbar ist, dass die Bedienelemente 14, 16, 18 des jeweiligen Ɯberlagerungsbereichs 26, 28 ineinander greifend angeordnet sind (vgl. Fig. 4). Hierbei kƶnnten benachbart angeordnete Bedienelemente 14, 16, 18 jeweils mehrere versetzt zueinander angeordnete VorsprĆ¼nge aufweisen, die ineinander greifend angeordnet sind (vgl. Fig. 4). Zudem mƶglich ist eine verzahnte Anordnung der Bedienelemente 14, 16, 18, wie beispielsweise bei einem Zahnrad.In the Figures 3 to 5 alternative embodiments are shown. Alternatively, it is conceivable that the operating elements 14, 16, 18 each partially overlap in the overlapping area 26, 28 (cf. FIGS. 3 and 5 ). Here, a first of the operating elements 14, 16, 18 could each have a side surface which is beveled with respect to the operating direction 44 and which could overlap a corresponding beveled side surface of a second operating element 14, 16, 18 adjacent to the operating element 14, 16, 18 (cf. Fig. 5 ). It is also conceivable that the operating elements 14, 16, 18 each have projections which are arranged offset to one another and which are arranged overlapping (cf. Fig. 3 ). It is also conceivable that the operating elements 14, 16, 18 of the respective overlapping area 26, 28 are arranged so as to interlock (cf. Fig. 4 ). Control elements 14, 16, 18 arranged next to one another could each have a plurality of projections arranged offset to one another, which are arranged interlocking (cf. Fig. 4 ). In addition, a toothed arrangement of the operating elements 14, 16, 18, such as in the case of a gearwheel, is possible.

Die Ɯberlagerungsbereiche 26, 28 weisen jeweils eine LƤnge von mehr als 10 % einer LƤnge der Bedienelemente 14, 16, 18 auf. Die Bedienelemente 14, 16, 18 weisen eine LƤnge von im Wesentlichen 2 cm und eine Breite von im Wesentlichen 2 cm auf. Die Ɯberlagerungsbereiche 26, 28, weisen eine LƤnge von im Wesentlichen 0,5 cm und eine Breite von im Wesentlichen 2 cm auf. Alternativ sind weitere, einem Fachmann als sinnvoll erscheinende LƤngen und/oder Breiten der Bedienelemente 14, 16, 18 und/oder der Ɯberlagerungsbereiche 26, 28 denkbar. Hierbei sind eine jeweilige LƤnge im Wesentlichen parallel zu der Bedienrichtung 44 und eine jeweilige Breite jeweils im Wesentlichen senkrecht zu der LƤnge und der Bedienrichtung 44 ausgerichtet.The overlapping areas 26, 28 each have a length of more than 10% of the length of the operating elements 14, 16, 18. The operating elements 14, 16, 18 have a length of essentially 2 cm and a width of essentially 2 cm. The overlapping areas 26, 28 have a length of essentially 0.5 cm and a width of essentially 2 cm. Alternatively, further lengths and / or widths of the operating elements 14, 16, 18 and / or the overlapping areas 26, 28 that appear sensible to a person skilled in the art are conceivable. Here, each length is essentially aligned parallel to the operating direction 44 and a respective width in each case essentially perpendicular to the length and the operating direction 44.

Die Bedieneinheit 12 weist eine Steuereinheit 30 auf, die dazu vorgesehen ist, in AbhƤngigkeit von einer BetƤtigungsposition 46, 48, 50, 52, 54 in dem Ɯberlagerungsbereich 26, 28 unterschiedliche Aktionen auszufĆ¼hren. Im vorliegenden AusfĆ¼hrungsbeispiel ist die Steuereinheit 30 zu einer absoluten GrĆ¶ĆŸeneinstellung vorgesehen, wobei jeder BetƤtigungsposition 46, 48, 50, 52, 54 ein eigener, fest vorgegebener Wert zugeordnet ist. Alternativ ist denkbar, dass eine Steuereinheit zu einer relativen GrĆ¶ĆŸeneinstellung vorgesehen ist, wobei bei einer BetƤtigung von in einer Reihe ausbildenden Bedienelementen und damit von von den Bedienelementen ausgebildeten Ɯberlagerungsbereichen in Form einer Gleitbewegung eine GrĆ¶ĆŸe je nach Bewegungsgeschwindigkeit und/oder BewegungslƤnge, insbesondere zurĆ¼ckgelegter Strecke, verƤndert wird.The operating unit 12 has a control unit 30 which is provided to carry out different actions as a function of an actuation position 46, 48, 50, 52, 54 in the overlay area 26, 28. In the present exemplary embodiment, the control unit 30 is provided for an absolute size setting, each actuation position 46, 48, 50, 52, 54 being assigned its own, fixed, predetermined value. Alternatively, it is conceivable that a control unit is provided for a relative size setting, with a size depending on the speed of movement and / or length of movement, in particular the distance covered, upon actuation of control elements formed in a row and thus overlay areas formed by the control elements in the form of a sliding movement. is changed.

Bei einem Verfahren zum Betrieb der HausgerƤtebedienvorrichtung 10 wird bei einer BetƤtigung einer ersten BetƤtigungsposition 46, die mittig in dem ersten Bedienelement 14 angeordnet ist, das erste Bedienelement 14 betƤtigt. Hierdurch wird das dem ersten Bedienelement 14 zugeordnete Sensorelement 20 ausgelƶst, woraufhin die Steuereinheit 30 eine erste Aktion ausfĆ¼hrt. Analog hierzu wird bei einer BetƤtigung einer zweiten BetƤtigungsposition 54, die mittig in dem zweiten Bedienelement 16 angeordnet ist, das zweite Bedienelement 16 betƤtigt, wodurch das dem zweiten Bedienelement 16 zugeordnete Sensorelement 22 ausgelƶst wird. Die Steuereinheit 30 fĆ¼hrt daraufhin eine zweite Aktion aus. In beiden FƤllen wird ein Anteil von im Wesentlichen 100 % eines durch die BetƤtigung eines der Bedienelemente 14, 16 ausgelƶsten Bediensignals von dem jeweiligen Sensorelement 20, 22 detektiert.In a method for operating the domestic appliance operating device 10, when a first operating position 46, which is arranged centrally in the first operating element 14, is operated, the first operating element 14 is operated. This triggers the sensor element 20 assigned to the first operating element 14, whereupon the control unit 30 carries out a first action. Analogously to this, when a second actuation position 54, which is arranged centrally in the second operating element 16, is actuated, the second operating element 16 is actuated, whereby the sensor element 22 assigned to the second operating element 16 is triggered. The control unit 30 then carries out a second action. In both cases, a portion of essentially 100% of an operating signal triggered by the actuation of one of the operating elements 14, 16 is detected by the respective sensor element 20, 22.

Bei einer BetƤtigung einer dritten BetƤtigungsposition 50, die mittig in dem ersten Ɯberlagerungsbereich 26 angeordnet ist, wird sowohl das erste Bedienelement 14 als auch das zweite Bedienelement 16 jeweils zu einem Anteil von im Wesentlichen 50 % betƤtigt. Hierdurch wird ein Anteil von im Wesentlichen 50 % eines durch die BetƤtigung des Ɯberlagerungsbereichs 26 ausgelƶsten Bediensignals von dem jeweiligen den, den Ɯberlagerungsbereich 26 ausbildenden, Bedienelementen 14, 16 zugeordneten Sensorelementen 20, 22 detektiert. Als Reaktion wird eine dritte Aktion ausgefĆ¼hrt.When a third actuation position 50, which is arranged centrally in the first superimposition area 26, is actuated, both the first operating element 14 and the second operating element 16 are each actuated to a proportion of essentially 50%. As a result, a proportion of essentially 50% of an operating signal triggered by the actuation of the overlay area 26 is detected by the respective sensor elements 20, 22 associated with the operating elements 14, 16 forming the overlay area 26. A third action is taken in response.

Eine Auswertung einer BetƤtigung des Ɯberlagerungsbereichs 26 bei einer BetƤtigungsposition 48, 52, die bei im Wesentlichen 25 % der LƤnge des Ɯberlagerungsbereichs 26 angeordnet ist, erfolgt analog. Bei einer BetƤtigung einer vierten BetƤtigungsposition 48 wird ein Anteil von im Wesentlichen 75 % des Bediensignals von dem, dem Bedienelement 14 zugeordneten Sensorelement 20 detektiert und ein Anteil von im Wesentlichen 25 % von dem, dem Bedienelement 16 zugeordneten Sensorelement 22 detektiert. Dabei wird eine vierte Aktion ausgefĆ¼hrt. Bei einer BetƤtigung einer fĆ¼nften BetƤtigungsposition 52 wird entsprechend ein Anteil von im Wesentlichen 25 % des Bediensignals von dem, dem Bedienelement 14 zugeordneten Sensorelement 20 detektiert und ein Anteil von im Wesentlichen 75 % von dem, dem Bedienelement 16 zugeordneten Sensorelement 22 detektiert. Dabei wird eine fĆ¼nfte Aktion ausgefĆ¼hrt. Analog hierzu lassen sich Auswertungen bei weiteren, einem Fachmann als sinnvoll erscheinenden BetƤtigungspositionen realisieren, beispielsweise bei im Wesentlichen einem Drittel der LƤnge des Ɯberlagerungsbereichs 26.An evaluation of an actuation of the overlay area 26 in an actuation position 48, 52, which is arranged at essentially 25% of the length of the overlay area 26, takes place analogously. When a fourth actuation position 48 is actuated, a portion of essentially 75% of the operating signal is detected by the sensor element 20 assigned to the operating element 14 and a portion of essentially 25% is detected by the sensor element 22 assigned to the operating element 16. A fourth action is carried out. When a fifth actuation position 52 is actuated, a proportion of essentially 25% of the control signal is accordingly detected by the sensor element 20 assigned to the control element 14 and a proportion of essentially 75% is detected by the sensor element 22 assigned to the control element 16. A fifth action is carried out. Analogously to this, evaluations can be carried out in the case of further actuation positions that appear sensible to a person skilled in the art, for example in the case of essentially one third of the length of the overlapping area 26.
