A "control electronics board unit" is to be understood in this context in particular as an electronic unit which has at least one board, preferably exactly one board, and electronic components arranged on the board and which is in particular part of a control unit of a domestic appliance having the domestic appliance control device. A “circuit board” is to be understood in particular as a unit which has a carrier body, in particular a plate-like carrier body, made of an electrically insulating material, on which conductor tracks made of an electrically conductive material are arranged and preferably fastened are. An electrically insulating material is to be understood as meaning, in particular, a material which, at 20 ° C., has a specific electrical resistance of at least 10 9 Ωm, in particular of at least 10 10 Ωm, preferably of at least 10 11 Ωm and particularly advantageously of at least 10 12 Ωm.

Darunter, dass die Bedienelektronikplatineneinheiten in einem montierten Zustand "in Zeilen übereinander" montiert sind, soll insbesondere verstanden werden, dass bei einer Betrachtung der zwei Bedienelektronikplatineneinheiten von einem Bedienbereich aus die zwei Bedienelektronikplatineneinheiten in einer zu einer Haupterstreckungsebene wenigstens einer der zwei Bedienelektronikplatineneinheiten parallelen Ebene übereinander angeordnet sind. Unter einer "Haupterstreckungsebene" einer Baueinheit soll insbesondere eine Ebene verstanden werden, welche parallel zu einer größten Seitenfläche eines kleinsten geometrischen Quaders ist, welcher die Baueinheit gerade noch vollständig umschließt, und insbesondere durch den Mittelpunkt dieses Quaders verläuft. Unter einem "Bedienbereich" soll in diesem Zusammenhang insbesondere ein räumlicher Bereich verstanden werden, in welchem sich ein Bediener bei einer vorschriftsmäßigen und/oder vorgesehenen Bedienung des Kochfeldes aufhält. Insbesondere ist der Bedienbereich durch eine räumliche Anordnung wenigstens einer Bedieneinheit, insbesondere einer Bedienoberfläche, und/oder durch zumindest eine Beschriftung und/oder Markierung zumindest einer Bedieneinheit gekennzeichnet. Unter einer "Bedienoberfläche" soll in diesem Zusammenhang eine in einem montierten Zustand durch einen Bediener anfassbare Oberfläche verstanden werden, welche zu einer Bedienung mittels einer Berührung und/oder Annäherung vorgesehen ist. Vorzugsweise sind Längsrichtungen der Bedienelektronikplatineneinheiten zumindest im Wesentlichen parallel zueinander angeordnet und vorzugsweise zumindest im Wesentlichen parallel zu einer Zeilenrichtung ausgerichtet. Unter einer "Längsrichtung" einer Baueinheit soll in diesem Zusammenhang insbesondere eine Richtung verstanden werden, welche parallel angeordnet ist zu einer längsten Kante eines kleinsten geometrischen Quaders, welcher die Baueinheit gerade noch vollständig umschließt.

Die Bedienelektronikplatineneinheiten können auf beliebige, dem Fachmann als sinnvoll erscheinende Art an der Bedienelektronikträgereinheit montiert sein, insbesondere mittels einer Schraubverbindung und vorzugsweise durch eine Rastverbindung.The fact that the control electronics board units are mounted "in rows on top of each other" in a mounted state is to be understood in particular to mean that when viewing the two control electronics board units from one control area, the two control electronics board units are arranged one above the other in a plane parallel to a main plane of extent at least one of the two control electronics board units are. Under a "main extension plane" of a structural unit, in particular a plane can be understood which is parallel to a largest side surface of a smallest geometric cuboid, which just completely encloses the structural unit, and in particular runs through the center of this cuboid. In this context, an “operating area” is to be understood as meaning, in particular, a spatial area in which an operator is present when operating the hob in accordance with regulations and / or as intended. In particular, the operating area is characterized by a spatial arrangement of at least one operating unit, in particular one operating surface, and / or by at least one lettering and / or marking of at least one operating unit. In this context, a “user interface” should be understood to mean a surface which can be touched by an operator in a mounted state and which is provided for operation by means of touch and / or approach. The longitudinal directions of the control electronics board units are preferably arranged at least substantially parallel to one another and preferably aligned at least substantially parallel to a row direction. A “longitudinal direction” of a structural unit is to be understood in this context, in particular, as a direction which is arranged parallel to a longest edge of a smallest geometric cuboid which just completely encloses the structural unit. The fact that two directions are “at least substantially parallel to one another” should be understood in particular to mean that the directions enclose a smallest angle which is a maximum of 15 °, in particular a maximum of 10 °, preferably a maximum of 5 ° and particularly advantageously a maximum of 1 °. A "line direction" is to be understood in particular as a direction parallel to a main plane of extent of at least one control electronics board unit, which is perpendicular to at least one shortest connecting line of the two control electronics board units with a perpendicular projection of the control electronics board units onto the main extent plane. The control electronics board units can be mounted on the control electronics carrier unit in any manner that appears sensible to a person skilled in the art, in particular by means of a screw connection and preferably by means of a latching connection.

Durch eine solche Ausgestaltung kann ein Kochfeld mit kochfeldbedienvorrichtung vorteilhaft weiterentwickelt werden. Insbesondere kann eine Montage vorteilhaft optimiert werden, da eine Vormontage der zwei Bedienelektronikplatineneinheiten an der Bedienelektronikträgereinheit ermöglicht werden kann. Ferner kann eine vorteilhafte Ausnutzung eines verfügbaren Bauraums bei einem Kochfeld erreicht werden. So kann bei begrenztem Bauraum eine Anzahl von Bedienelektronikplatineneinheiten erhöht werden. Insbesondere kann eine Mehrzahl von TouchSlidern, insbesondere zumindest vier und vorzugsweise wenigstens fünf Touch-Slider,zum Einsatz kommen. Unter einem "Touch-Slider" soll in diesem Zusammenhang insbesondere eine Bedieneinheit verstanden werden, welche durch ein Gleiten eines Fingers eines Bedieners auf einer vorzugsweise entsprechend gekennzeichneten Bedienoberfläche bedienbar ist, wobei in wenigstens einem Betriebszustand durch das Gleiten des Fingers auf der Bedienoberfläche insbesondere ein Inkrementieren oder Dekrementieren einer Stellgröße, insbesondere einer Heizstufe, erfolgt. Die Bedienoberfläche kann insbesondere gekrümmt, beispielsweise zumindest teilweise kreisringförmig, ausgebildet sein.

Darunter, dass die Bedienoberfläche "zu wenigstens einem Großteil geradlinig" ausgebildet ist, soll insbesondere verstanden werden, dass eine Randlinie der Bedienoberfläche zusammengenommen auf einer Länge von zumindest 60 %, insbesondere von mindestens 70 %, vorzugsweise von wenigstens 80 % und besonders vorteilhaft von zumindest 90 % einer Gesamtlänge der Randlinie geradlinig ist. Des Weiteren kann eine Flexibilität bei einer Platzierung der Bedienelektronikplatineneinheiten vorteilhaft gesteigert werden, wobei insbesondere verschiedene Layouts dank der Flexibilität bewerkstelligt werden können. Die Bedienelektronikplatineneinheiten können, trotz des begrenzten Bauraums, an einem für einen Bediener intuitiv einsichtigen und ergonomischen Ort am Kochfeld, platziert werden.Such a configuration can advantageously be used to further develop a hob with a hob control device. In particular, assembly can advantageously be optimized, since pre-assembly of the two control electronics board units on the control electronics carrier unit can be made possible. Furthermore, an advantageous use of an available Space can be achieved with a hob. With a limited installation space, a number of control electronics board units can be increased. In particular, a plurality of touch sliders, in particular at least four and preferably at least five touch sliders, can be used. In this context, a "touch slider" is to be understood in particular as an operating unit which can be operated by sliding a finger of an operator on a preferably appropriately labeled operating surface, with in particular incrementing in at least one operating state by sliding the finger on the operating surface or a manipulated variable, in particular a heating level, is decremented. The user interface can in particular be curved, for example at least partially circular. Preferably, however, the user interface is at least for the most part rectilinear. The fact that the user interface is "at least largely straight" should be understood in particular to mean that an edge line of the user interface taken together over a length of at least 60%, in particular of at least 70%, preferably of at least 80% and particularly advantageously of at least 90% of a total length of the edge line is straight. Furthermore, flexibility in the placement of the operating electronics board units can advantageously be increased, with in particular different layouts being able to be implemented thanks to the flexibility. The control electronics board units can, despite the limited installation space, be placed at an ergonomic location on the hob that is intuitively visible to an operator.

Vorzugsweise umfasst die Sensoreinheit ein Sensorelement aus einem elektrisch leitenden Material und ist dazu vorgesehen, eine Berührung des Sensorelements und/oder eine Annäherung an das Sensorelement zu detektieren, vorzugsweise durch Messung einer Veränderung einer elektrischen Kapazität des Sensorelements. Hierdurch kann ein Bedienkomfort vorteilhaft gesteigert werden.In the embodiment of the invention, both control electronics board units each have at least one touch and / or proximity sensor. In this context, a “touch and / or proximity sensor” is to be understood in particular as a sensor unit which is provided to allow an element of the sensor unit to be touched and / or an element of the sensor unit to be approached, in particular by a finger of an operator detect. The sensor unit preferably comprises a sensor element made of an electrically conductive material and is provided to detect contact with the sensor element and / or an approach to the sensor element, preferably by measuring a change in an electrical capacitance of the sensor element. In this way, ease of use can advantageously be increased.

In this way, an advantageous protection for the control electronics board units can be created. In particular, penetration of dirt and / or moisture can at least largely be avoided. Furthermore, a user-friendly operating unit can be provided. If the domestic appliance control device has a hob plate with which the control panel is formed in one piece, an advantageously simple design of a hob can be achieved. Furthermore, the cleaning effort can be reduced. In particular, an appealing design can also be created in this way.

The proximity sensors 22a-g, 24a-g, 26a-g of the control electronics board units 14, 16, 36, 70 each detect in a known manner a touch of the control panel 40 in an area above the respective proximity sensor 22a-g, 24a-g, 26a-g. By means of a control unit (not shown) of the control electronics board units 14, 16, 36, 70, a sliding direction of a finger of an operator over the respectively assigned touch slider can be based on a time sequence of activation of the proximity sensors 22a-g, 24a-g, 26a-g 30, 32, 34, 52, 54 can be determined. Furthermore, on the basis of a time between the activation of a proximity sensor 22a-g, 24a-g, 26a-g and a proximity sensor 22a-g, 24a-g, 26a-g adjacent to this proximity sensor 22a-g, 24a-g, 26a-g a sliding speed of the finger can be determined via the respectively assigned touch slider 30, 32, 34, 52, 54. Both the sliding direction and the sliding speed can be taken into account by the respective control unit for triggering a control event, in particular for setting the heating level of the associated heating unit 58a-e.
