Das Gehäuse wird also von oben auf die Trägereinrichtung aufgelegt, wobei zur Fixierung jeder Fortsatz in die zugehörige Ausnehmung oder Öffnung in Eingriff gebracht wird, und wird durch die Schwerkraft - und gegebenenfalls eine zusätzliche gleichgerichtete Presskraft - auf der Trägereinrichtung gehalten sowie durch die Fixierung an einem seitlichen Verrutschen gehindert.The control and / or display device is protected by the housing against external influences, in particular electrostatic Charging (ESD) by touch or dirt, protected and forms together with the housing a pre-assembled control and / or display unit. The assembly of this unit is particularly easy due to the detachable and positive or non-positive connection between extension and receptacle, because the housing easily on the carrier or can be placed and fixed at the same time and no additional connections are required. The support means preferably has at least one bearing surface for the housing, which points upward, ie opposite to the gravitational force (gravity). The housing is thus placed from above onto the carrier device, wherein each extension is brought into the associated recess or opening for fixing, and is held by gravity - and optionally an additional rectified pressing force - on the support means and by the fixation on a prevented lateral slippage.

Die Verbindung zwischen Fortsatz und Ausnehmung oder Öffnung kann insbesondere im Wesentlichen in Richtung der Erdanziehungskraft (Schwerkraft) erfolgen, so dass das Auflegen und das Fixieren des Gehäuses auf der Trägereinrichtung mit einem einzigen Handgriff bewirkt werden kann.In particular, the connection between extension and recess or opening can take place essentially in the direction of gravity (gravity), so that the placing and fixing of the housing on the carrier device can be effected with a single handle.

Alternativ oder zusätzlich ist es auch möglich, die Verbindung zwischen Fortsatz und Ausnehmung oder Öffnung als Schnapp- oder Rastverbindung auszubilden, für deren Herstellen oder Lösen eine bestimmte Rastkraft erforderlich ist. Dadurch kann die Verbindung auch eine gewisse Gewichtskraft der Steuer- und/oder Anzeigeeinheit (Steuer- und/oder Anzeigevorrichtung mit Gehäuse) auffangen und die Einheit kann auch an einer senkrechten oder schrägen Trägerwand befestigt werden..Alternatively or additionally, it is also possible to form the connection between extension and recess or opening as a snap or latching connection, for the production or release of a certain locking force is required. As a result, the connection can also absorb a certain weight of the control and / or display unit (control and / or display device with housing) and the unit can also be attached to a vertical or oblique support wall.

The sealing mat 8 has a number of slots (lead-through opening) corresponding to the number of plug-in contact elements 4 of the corresponding contact group 40 to 44 in that the respective contact parts 42 'can be pushed through, but which are smaller than the base parts 4', so that the sealing mats 8 rest on the base parts 4 'of the plug contact elements 4. The sealing mats 8 are preferably made of an elastic material, so that the slots have something smaller can be formed as the contact parts 42 'of the plug contact elements 4 and thus the sealing mats 8 are held under a spring tension (elastic deformation force) on the plug contact elements 4 each contact group 40 to 44.

Das in den FIG 3 und 4 dargestellte Gehäuse 10 ist zur Unterbringung und Montage einer - in den FIG 3 und 4 nicht dargestellten - Steuer- und/oder Anzeigevorrichtung 1 gemäß den FIG 1 und 2 vorgesehen und ausgebildet. Das Gehäuse 10 weist seitlich zwei im wesentlichen parallel zueinander verlaufende, ebenfalls trapezförmige, Wände auf. Eine innere Seitenwand ist mit 11 bezeichnet, während die äußere Seitenwand mit 12 bezeichnet ist. Das Gehäuse 10 ist nach oben zu einer - nicht dargestellten - Kochfeldplatte hin offen, wodurch insbesondere zwischen der inneren Seitenwand 11 und der äußeren Seitenwand 12 ein Spalt (Zwischenraum) 19 und innerhalb der inneren Seitenwand 11 eine Beschickungsöffnung (Zugangsöffnung) gebildet sind. Durch die von der inneren Seitenwand 11 umgrenzte obere Beschickungsöffnung wird die Steuer- und/oder Anzeigevorrichtung 1 in das Gehäuse 10 eingelegt. Der Spalt 19 dient dagegen der thermischen Isolierung der in dem Gehäuse 10 unterzubringenden temperaturempfindlichen elektronischen Komponenten auf der Steuer- und/oder Anzeigevorrichtung 1.The housing 10 shown in FIGS. 3 and 4 is provided and designed for housing and mounting a control and / or display device 1 (not shown in FIGS. 3 and 4) according to FIGS. 1 and 2.

The housing 10 is upwardly to a - not shown - Hob plate, whereby in particular between the inner side wall 11 and the outer side wall 12, a gap (gap) 19 and within the inner side wall 11, a feed opening (access opening) are formed. By the bounded by the inner side wall 11 upper feed opening, the control and / or display device 1 is inserted into the housing 10. In contrast, the gap 19 serves to thermally insulate the temperature-sensitive electronic components to be accommodated in the housing 10 on the control and / or display device 1.

Nach unten versetzt zur Oberkante ist an der Innenseite der inneren Seitenwand 11 ein umlaufender Auflagesockel 14 für die Steuer- und/oder Anzeigevorrichtung 1 angeordnet. An den beiden schräg verlaufenden Seiten des trapezförmigen Gehäuses 10 ist ein Auflagesockel (Auflagefläche) 13 gebildet, auf dem die Steuer- und/oder Anzeigevorrichtung 1 ebenfalls aufgelegt wird. In dem Auflagesockel 13 sind nun Öffnungen 141 und 142 sowie 143 und 144 zum Durchführen jeweils einer der Kontaktgruppen 41 bzw. 42 bzw. 43 bzw. 44 der nicht dargestellten Steuer- und/oder Anzeigevorrichtung 1 ausgebildet. An der kürzeren der parallel zueinander verlaufenden Trapezkanten der inneren Seitenwand 11 schließt sich ein unterer Teil des Auflagesockels 13 an, in dem ebenfalls eine Öffnung 140 für die Kontaktgruppe 40 der Steuer- und/oder Anzeigevorrichtung 1 ausgebildet ist. Unten schließen sich an die innere Seitenwand 11 Seitenwände 18 und an diese ein in zwei Stufen ausgebildeter Boden des Gehäuses an. Ein im weiter auslaufenden Teil des trapezförmigen Gehäuses 10 angeordnetes Bodenteil ist mit 16 und ein im sich verjüngenden Teil des Gehäuses 10 angeordnetes zweites Bodenteil mit 17 bezeichnet. Das Bodenteil 17 ist höher angeordnet als das Bodenteil 16, so dass ein treppen- oder stufenartig ausgebildeter Gehäuseboden verwirklicht ist. An der inneren Seitenwand 11 sind ferner auch Rast- oder Schnappelemente 15 angeordnet zum lösbaren Befestigen der Steuer- und/oder Anzeigevorrichtung 1. Der von den Gehäusebodenteilen 16 und 17 und den Seitenwänden 11 und 18 begrenzte Innenraum des Gehäuses 10 zur Aufnahme der Steuer- und/oder Anzeigevorrichtung 1 ist mit 25 bezeichnet.Downwardly offset from the upper edge, a circumferential support base 14 for the control and / or display device 1 is arranged on the inner side of the inner side wall 11. On the two sloping sides of the trapezoidal housing 10, a support base (bearing surface) 13 is formed, on which the control and / or display device 1 is also placed. In the support base 13 are now openings 141 and 142 and 143 and 144 for performing each one of the contact groups 41 or 42 or 43 or 44 of the control and / or display device 1, not shown. At the shorter of parallel trapezoidal edges of the inner side wall 11, a lower part of the support base 13 connects, in which also an opening 140 for the contact group 40 of the control and / or display device 1 is formed. Down close to the inner side wall 11 side walls 18 and to this a trained in two stages bottom of the housing. A further arranged in the expiring part of the trapezoidal housing 10 bottom part is denoted by 16 and a arranged in the tapered portion of the housing 10 second bottom part 17. The bottom part 17 is arranged higher than the bottom part 16, so that a stepped or step-like design housing bottom is realized. On the inner side wall 11 also locking or snap elements 15 are also arranged for releasably securing the control and / or display device 1. The limited by the housing bottom parts 16 and 17 and the side walls 11 and 18 interior of the housing 10 for receiving the control and / or display device 1 is denoted by 25.

An der Unterseite des Gehäuses 10, insbesondere an der äußeren Seitenwand 12, sind mehrere Fortsätze (Vorsprünge, Nasen) 61 angeformt, mit denen das Gehäuse 10 auf oder in einer Trägereinrichtung (Muldenwanne, Trägerwanne) 80 unterhalb der - nicht dargestellten - Kochfeldplatte des Kochfeldes positioniert werden kann. Dazu weist die Trägereinrichtung 80 in einem Auflagebereich für das Gehäuse 10 für jeden Fortsatz 61 eine zugehörige, in den Umrissen dem Fortsatz 61 angepasste Aufnahme 81 auf, in die der Fortsatz 61 formschlüssig eingreift. Dadurch wird das Gehäuse 10 von der Trägereinrichtung 80 getragen und zugleich gegen seitliches Verrutschen gesichert. Die Verbindungspaare aus jeweils einem Fortsatz 61 und einer Aufnahme 81 bilden also lösbare Fixiermittel zum Fixieren des Gehäuses 10 an der Trägereinrichtung 80.On the underside of the housing 10, in particular on the outer side wall 12, a plurality of projections (projections, lugs) 61 are formed, with which the housing 10 on or in a support means (trough, carrier trough) 80 below - not shown - Hob plate of the hob can be positioned. For this purpose, the carrier device 80 in a support region for the housing 10 for each extension 61 an associated, in the contours of the extension 61 adapted receptacle 81 into which the extension 61 engages positively. Characterized the housing 10 is supported by the support means 80 and at the same time secured against lateral slipping. The connection pairs Each of an extension 61 and a receptacle 81 thus forms releasable fixing means for fixing the housing 10 to the support device 80.

Die Form und Gestalt der Fortsätze 61 und der Aufnahmen 81 ist natürlich nicht auf die dargestellte Ausführungsform beschränkt, sondern kann vielfältig variiert werden, abhängig von der gewünschten Fixierwirkung. Insbesondere kann anstelle einer formschlüssigen Verbindung zwischen Fortsatz 61 und Aufnahme 81, die in einer Richtung, nämlich der Auflagerichtung, ungesichert ist, auch eine kraftschlüssige Verbindung oder eine Rast- oder Schnappverbindung verwirklicht sein, um das Gehäuse 10 vor einem unbeabsichtigten Lösen von der Trägereinrichtung 80 in allen Richtungen, also auch in der Auflagerichtung, zu sichern. Außerdem können auch in kinematischer Umkehr Fortsätze an der Trägereinrichtung 80 und Aufnahmen an dem Gehäuse 10 vorgesehen sein. Die Aufnahmen 81 können durchgehende Öffnungen oder auch unten geschlossene Ausnehmungen sein. Falls die Trägereinrichtung 80 aus einem Metallblech, insbesondere einem Stahlblech, gebildet ist, können die Öffnungen einfach gestanzt sein. Ferner können Fortsätze mittels ausgestellter Lappen gebildet sein.The shape and shape of the projections 61 and the receptacles 81 is of course not limited to the illustrated embodiment, but can be varied in many ways, depending on the desired fixing effect. In particular, instead of a positive connection between extension 61 and receptacle 81, which is unsecured in one direction, namely the support direction, also a frictional connection or a snap or snap connection can be realized to the housing 10 against accidental release of the support device 80th in all directions, including in the direction of support, secure. In addition, extensions on the carrier device 80 and receptacles on the housing 10 may also be provided in kinematic reversal. The receptacles 81 may be through openings or also closed down recesses. If the carrier device 80 is formed from a metal sheet, in particular a steel sheet, the openings can be simply punched. Furthermore, extensions can be formed by means flared lobes.

Der Fortsatz 91 greift in eine Öffnung 85 in dem Blech der Trägereinrichtung 80 ein. Der Fortsatz 91 hat seitlich zwei Anlaufschrägen 92 und 93 als Führungen, um das Einführen des Fortsatzes 91 in die Öffnung 85 zu erleichtern. Von dem entsprechend engeren Querschnitt an der äußersten Stelle weitet sich der Fortsatz 91 in seinem Querschnitt bis zu einem insbesondere quaderförmigen inneren Bereich mit konstantem Querschnitt auf, der formschlüssig an der Öffnung 85 von innen anliegt.At the longer of the two mutually parallel sides of the trapezoid of the outer side wall 12 of the housing 10, a downwardly projecting extension 91 is now formed or formed, the shape of which can be seen in more detail in FIG. The extension 91 engages in an opening 85 in the plate of the support means 80 a. The extension 91 has laterally two chamfers 92 and 93 as guides to facilitate the insertion of the extension 91 in the opening 85. From the correspondingly narrower cross-section at the outermost point, the extension 91 widens in its cross section up to a particular cuboid-shaped inner region with a constant cross-section, which bears against the opening 85 from the inside in a form-fitting manner.

Wie aus FIG 9 zu erkennen ist, ist der tiefste Bodenteil 16 des Gehäuses 10 durch eine weitere Öffnung 86 in der Trägereinrichtung 80 geführt, wobei kein Formschluss erreicht werden muss. Dadurch kann in diesem Bereich im Gehäuse 10 mehr Platz für Komponenten der Steuer- und/oder Anzeigevorrichtung 1 bereitgestellt werden.As can be seen from FIG 9, the deepest bottom part 16 of the housing 10 is guided through a further opening 86 in the support means 80, wherein no positive connection must be achieved. As a result, more space for components of the control and / or display device 1 can be provided in the housing 10 in this area.

Die Konzeption der Steuer- und/oder Anzeigeeinheit gemäß der Erfindung hat den Vorteil, dass die Steuer- und/oder Anzeigevorrichtung 1 in dem Gehäuse 10 vormontiert werden kann und dann als Transporteinheit transportiert und/oder als Montageeinheit am Kochfeld montiert werden kann.The design of the control and / or display unit according to the invention has the advantage that the control and / or display device 1 can be pre-assembled in the housing 10 and then transported as a transport unit and / or mounted as a mounting unit on the hob.

Für den Schutz der Steuer- und/oder Anzeigevorrichtung 1 kann zum Verschließen der Beschickungsöffnung ein in den Abmessungen angepasster Deckel 70 vorgesehen sein, der in den FIG 11 und 12 dargestellt ist.
