Description
Die Erfindung betrifft eine Herdblende aus Kunststoff für Kochherde, welche Bedienteile und Funktionsanzeigen für den Herd in Ausnehmungen an ihrer Vorderseite sowie elektrischen Verbindungen hierfür erhält.The invention relates to a stove cover made of plastic for cookers, which controls and function indicators for the stove in recesses on the front as well as electrical connections for this.
Derartige Herdblenden sind bereits bekannt, beispielsweise aus der DE 39 27 247 A1. Dort ist unter anderem eine Herdblende beschrieben, bei welcher die Bedienteile und die Anzeigen fest in die Herdblende eingebaut sind, wobei die Steuerelektronik auf einer oder mehreren Leiterplatten angeordnet ist, die in Einschüben in dem sich hinter der Herdblende anschließenden Kasten eingeschoben sind.Such stove tops are already known, for example from DE 39 27 247 A1. There is described, among other things, a stove cover, in which the operating parts and the displays are built into the stove top, with the control electronics is arranged on one or more printed circuit boards, which are in slots in which the box behind the stove cover is inserted.
Es ist auch allgemein bei elektrischen Herden bekannt, dass die Herdblende aus einem Blechteil besteht, auf welchem in einer Reihe von Montagegängen die Bedienelemente, die Schalter, die Anzeigebaugruppen und andere Teile montiert werden. In solchen Herdblenden sind die elektrischen Verbindungen zwischen den elektrischen Bauteilen und den Leiterplatten mit der Steuerelektronik durch eine Verkabelung miteinander verbunden.It is also common knowledge in electric stoves that the stove top is made of consists of a sheet metal part, on which the control elements, the switches, the display assemblies and other parts become. In such stove tops, the electrical connections are between the electrical components and the printed circuit boards with the control electronics a wiring connected.
Aus der US 5,559,364 ist ein Leiterrahmen ("leadframe") bekannt, mit dem Anschlüsse eines elektronischen Mikrochips nach außen geführt werden und der mitsamt dem Mikrochip in Harz eingegossen wird.From US 5,559,364 a lead frame ("leadframe") is known, with the connections of an electronic microchip and the whole the microchip is poured into resin.
Aufgabe der Erfindung ist es, den Montageaufwand weiter zu reduzieren und eine Herdblende zu schaffen, welche flexibel an die Anforderungen des Kunden anpassbar ist, jedoch schon voll vormontiert ausgeliefert werden kann. The object of the invention is to further reduce the assembly effort and a To create a stove top, which can be flexibly adapted to the requirements of the customer is, but can be delivered fully pre-assembled.
Zur Lösung dieser Aufgabe schlägt die Erfindung die im Anspruch 1, kennzeichnenden
Teil, dargestellten Merkmale vor.To achieve this object, the invention proposes the characterizing in
Grundidee der Erfindung ist es, durch Ausbildung der Herdblende in Kunststoff alle notwendigen Bauelemente oder Trägerelemente bereits bei der Herstellung anzuspritzen, entsprechende Öffnungen für optionale Funktionsteile vorzusehen sowie die Verkabelung in der Herdblende bereits beim Spritzvorgang voll funktionsfähig vorzusehen.The basic idea of the invention is to design the stove top in plastic all necessary components or carrier elements already during manufacture to be molded on, to provide appropriate openings for optional functional parts and the wiring in the stove top is already full during the spraying process to provide functional.
In weiterer Ausbildung der Erfindung ist vorgesehen, daß in der Vorderseite der Herdblende eine Reihe von Öffnungen vorgesehen sind, in welche - optional - Bedienungselemente oder Leiterplatten mit Anzeigen einsetzbar sind, wobei diese Öffnungen im unbenutzten Zustand jedoch durch Deckel verschlossen sind.In a further embodiment of the invention it is provided that in the front of the Stove panel a number of openings are provided, in which - optionally - Controls or circuit boards with displays can be used, these However, openings in the unused state are closed by covers.
Hierdurch ist es möglich, je nach Ausstattung des Herdes mehrere weitere Anzeigemodule einzusetzen, welche aus einer Leiterplatte mit Steuerelektronik sowie darauf angeordneter Anzeige ausgebildet sind. Diese Anzeigemodule können nach Entfernung eines Deckels in die Herdblende in die entsprechende Öffnung eingeschnappt werden.This makes it possible, depending on the equipment of the stove, several more Use display modules, which consist of a circuit board with control electronics and display arranged thereon are formed. These display modules can after removing a lid in the stove cover in the corresponding opening to be snapped.
In bevorzugter weiterer Ausbildung der Erfindung ist vorgesehen, daß die Leiterstreifen als Stanz-, Biege- oder Drahtformteile ausgebildet sind, welche an ihren Endstellen als Anschlußstifte aus dem Kunststoff heraustreten und mit den Steckerleisten von einschiebbaren oder einschnappbaren Leiterplatten in Wirkverbindung treten.In a preferred further embodiment of the invention it is provided that the Conductor strips are formed as stamped, bent or shaped wire parts, which on step out their terminal points as connecting pins from the plastic and with the Power strips of insertable or snap-in circuit boards in Connect actively.
Diese Ausbildung ist deshalb besonders interessant, da die Leiterstreifen, - bereits die volle Verdrahtung der Herdblende darstellend - in das Spritzwerkzeug für die Herdblende eingelegt werden und nach dem Spritzvorgang an den vorgesehenen Stellen als Anschlußstifte aus dem Kunststoff herausragen, so daß sie nur noch - falls vorgesehen - - mit einer Steckerleiste versehen werden müssen. Die einschnappbaren Anzeigemodule finden in den ihnen zugeordneten Öffnungen in der Herdblende an passender Stelle bereits die entsprechenden Anschlußstifte vor und treten beim Einschnappen unmittelbar mit diesen in elektrische Wirkverbindung.This training is particularly interesting because the conductor strips - already representing the full wiring of the stove top - in the injection mold for the Stove cover are inserted and after the spraying process on the intended Protrude as connecting pins from the plastic so that they only - if provided - - must be provided with a power strip. The snap-in display modules can be found in the openings assigned to them in the stove cover in front of the appropriate connection pins and immediately snap into electrical when snapped Operatively connected.
Alternativ zu der vorbeschriebenen Ausführung der Leiterstreifen kann in weiterer Ausbildung der Erfindung vorgesehen sein, daß die eingespritzten Leiterstreifen als metallisierte Kunststoffeinlegeteile ausgebildet sind, die in die Herdblende eingebettet sind.As an alternative to the above-described design of the conductor strips, further Training of the invention can be provided that the injected conductor strips as Metallized plastic inserts are formed in the stove top are embedded.
Diese metallischen Leiterstreifen können auch anstatt einer üblichen Metallisierung im Heißprägeverfahren aufgebracht werden.These metallic conductor strips can also be used instead of a conventional metallization be applied by hot stamping.
In vorteilhafter Weiterbildung der Erfindung können die Trägerelemente, die an die Herdblende angespritzt sind, einerseits als Aufnahmen für versenkbare Knebel und andererseits als Basis für den Anbau der zu betätigenden Schalter dienen.In an advantageous development of the invention, the carrier elements attached to the Stove cover are molded, on the one hand as receptacles for retractable gags and on the other hand serve as the basis for the attachment of the switches to be operated.
Schließlich kann gemäß weiterer Ausbildung der Erfindung vorgesehen sein, daß die Leiterplatten mit der Steuerelektronik für den Herd als Einschübe ausgebildet sind und an ihren in Einschubrichtung vorderen Kanten Steckerleisten tragen, die in ihrer Anschlußbelegung auf die. zugeordneten Anschlußstiftleisten in der Herdblende abgestimmt sind.Finally, according to a further embodiment of the invention, it can be provided that the printed circuit boards with the control electronics for the stove are designed as inserts are and carry on their front edges in the direction of insertion connector strips that in their pin assignment on the. assigned pin headers in the Stove cover are matched.
