Description

Haushaltsgerät mit FrontbiendeHousehold appliance with front flaps
Die vorliegende Erfindung betrifft ein Haushaltgerät, wie z.B. einen Herd, mit einer sich im wesentlichen über die Breite des Haushaltsgerätes an dessen Vorderseite erstreckenden Frontblende, die durch ein Strangpreßprofilteil aus Metall gebildet und an dem Haushaltsgerät befestigt ist, und mit der Frontblende zugeordneten Bedien- und/oder Anzeigeele- menten des Haushaltsgerätes.The present invention relates to a household appliance, e.g. a stove, with a front panel which extends essentially across the width of the household appliance on its front and is formed by an extruded metal part and is fastened to the household appliance, and with operating and / or display elements of the household appliance associated with the front panel.
Ein derartiges Haushaltsgerät ist bekannt aus dem deutschen Gebrauchsmuster G 87 06 669, wobei die als Strangpreßprofil ausgebildete Frontblende in leicht gegenüber der vertikal geneigter Stellung an der Oberseite eines Elektroherdes montiert ist. Die Frontblende besitzt beidseitig eine Führungsbahn für nachstehend beschriebene Blendenteile sowie obere und untere, horizontale nutartige Führungselemente, welche die vorgenannte Führungsbahn begrenzen. Femer besitzt die Frontblende an der Unterseite einen angeformten Befestigungsflansch und an der Oberseite einen ebenfalls angeformten flanschartigen Ansatz, welcher eine nach unten offene Einhängenut und im Anschluß daran eine Was- serauffangrinne besitzt. In die Führungselemente entlang der Führungsbahn der Frontblende einschiebbar ist eine Frontplatte aus einem glasartigen Kunststoff, die im Bereich von Fenstern transparente Anzeigefelder besitzt und in diesem Bereich mit Symbolen oder dergleichen bedruckt sein kann. Nachteilig bei diesem Elektroherd ist, daß beim Anheben desselben durch eine Person, beispielsweise beim Transport oder beim Einbau des Herdes, an dessen Frontblende diese beschädigt werden kann.Such a household appliance is known from the German utility model G 87 06 669, the front panel designed as an extruded profile being mounted on the top of an electric cooker in a position slightly opposite to the vertically inclined position. The front panel has a guideway on both sides for the diaphragm parts described below as well as upper and lower, horizontal groove-like guide elements which limit the aforementioned guideway. The front panel also has a molded-on mounting flange on the underside and a likewise molded-on flange on the top, which has a hanging groove that is open at the bottom and then has a water gutter. A front plate made of a glass-like plastic can be inserted into the guide elements along the guideway of the front panel, which has transparent display fields in the area of windows and can be printed with symbols or the like in this area. The disadvantage of this electric cooker is that when it is lifted by a person, for example when transporting or installing the cooker, the front panel can damage it.
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Haushaltsgerät bereitzustellen, bei dem die mechanische Stabilität der Frontblende erhöht ist. Erfindungsgemäß ist dies bei einem Haushaltsgerät nach dem Oberbegriff des Patentanspruches 1 dadurch gelöst, daß die Frontblende sich um eine vertikale Achse im wesentlichen gleichmäßig gebogen über die Breite der Frontblende zylinderwandabschnitts- förmig erstreckt. Da Haushaltsgeräte erfahrungsgemäß beim Transport bzw. bei der Montage regelmäßig an der Frontblende gegriffen und gehoben bzw. verschoben werden, ist sowohl deren Eigenstabilität als auch deren sichere Befestigung am Haushaltsgerät besonders wichtig. Durch die gebogene Ausgestaltung der Frontblende wird auf fertigungstechnisch sehr einfache Weise zum einen deren Stabilität deutlich erhöht und zum anderen zusätzliche Grifffläche an der Unterseite der Frontblende zum Erleichtern des Anhebens des Haushaltsgerätes bereitgestellt. Dabei ist die zusätzliche Grifffläche vorteilhafterweise im wesentlichen in der Mitte der Frontblende bereitgestellt, was zur symmetrischen Krafteinleitung in diese beim Anheben führt. Dies führt auch zu einer gleichmäßigen Belastung der häufig symmetrisch zur Mittelachse der Frontblende angeordneten Befestigungsstellen zwischen Haushaltsgerät und Frontblende. Zusätzlich wurde festgestellt, daß durch die nach vorne gebogene Ausgestaltung der Frontblende deren Temperatur deutlich reduziert wird.The object of the present invention is to provide a generic household appliance in which the mechanical stability of the front panel is increased. According to the invention this is achieved in a household appliance according to the preamble of claim 1 in that the front panel extends around a vertical axis in a substantially uniform manner across the width of the front panel in the shape of a cylinder wall section. Since experience has shown that household appliances are regularly gripped and lifted or moved on the front panel during transport or assembly, both their inherent stability and their secure attachment to the household appliance are particularly important. The curved design of the front panel on the one hand increases its stability significantly in terms of production technology and on the other hand provides additional grip area on the underside of the front panel to make it easier to lift the household appliance. The additional grip surface is advantageously provided essentially in the middle of the front panel, which leads to the symmetrical introduction of force into it when lifting. This also leads to a uniform load on the fastening points, which are often arranged symmetrically to the central axis of the front panel, between the household appliance and the front panel. In addition, it was found that the temperature of the front panel is significantly reduced by the forward-curved configuration.
Vorzugsweise ist die Frontblende an einem Blendenrahmen gehaltert, der an dem Haushaltsgerät befestigt ist. Durch den Blendenrahmen werden die eingeschränkten Gestal- tungsmöglichkeiten der Strangpreß-Frontblende bezüglich des Vorsehens von Befestigungsabschnitten in den Randbereichen der Frontblende deutlich erweitert. Insbesondere ist ein Befestigen der Frontblende bzw. des Blendenrahmens durch horizontal angeordnete Schrauben oder ähnlichem möglich. Eine Verringerung der Wärmeleitung vom Haushaltsgerät bzw. dessen Komponenten zur Frontblende kann dadurch erreicht werden, daß der Blendenrahmen aus einem geeigneten Kunststoff besteht. Erfindungsgemäß kann durch den Rahmen auf besonders einfache Weise noch eine weitere Funktion übernommen werden, wenn der Blendenrahmen zumindest eine Rahmenplatte aufweist zum Abdecken von einer sich durch den nach vorne gebogenen Verlauf der Bedienblende ergebenden kreissegmentförmigen Öffnung zwischen dem Haushaltsgerät und der Bedien- blende. Es müssen also keine zusätzlichen Abdeckteile montiert werden, oder das Gehäuse des Haushaltsgerätes alleine wegen der Verwendung der erfindungsgemäß gebogenen Blende anders gestaltet werden als bei Haushaltsgeräten desselben Typs, bei denen eine ungebogene, ebene Frontblende verwendet wird. Die Abdeckung ist besonders wichtig, um das Eindringen von aus dem Haushaltsgerät unterhalb der Frontblende austretenden Wrasen oder ähnlichem in den Bereich hinter der Frontblende zu vermeiden. Zur weiteren Erhöhung der Stabilität der Blendenanordnung weisen der Blenden- rahmen und die Frontblende korrespondierende Abstützabschnitte auf, in denen beide bei Kraftbeaufschlagung in vertikaler Richtung formschlüssig miteinander verbunden sind. Dadurch ist ein stabiler und sicherer Aufbau des Haushaltsgerätes gewährleistet, falls es möglich ist, die Frontblende lediglich am Blendenrahmen zu greifen und zu heben.The front panel is preferably held on a panel frame which is attached to the household appliance. The restricted design options of the extruded front cover with regard to the provision of fastening sections in the edge areas of the front cover are significantly expanded by the cover frame. In particular, the front panel or the panel frame can be fastened by means of horizontally arranged screws or the like. A reduction in the heat conduction from the household appliance or its components to the front panel can be achieved in that the panel frame consists of a suitable plastic. According to the invention, a further simple function can be taken over by the frame if the cover frame has at least one frame plate for covering an opening in the form of a segment of a circle between the household appliance and the control panel, which opening is formed by the forwardly curved course of the control panel. No additional cover parts have to be installed, or the housing of the household appliance can be designed differently from household appliances of the same type, in which an unbent, flat front panel is used, solely because of the use of the panel bent according to the invention. The cover is particularly important to prevent vapors or the like escaping from the household appliance below the front panel from entering the area behind the front panel. To further increase the stability of the panel arrangement, the panel frame and the front panel corresponding support sections, in which both are positively connected to each other in the vertical direction when force is applied. This ensures a stable and secure construction of the household appliance, if it is possible to grip and lift the front panel only by the panel frame.
Gemäß einer bevorzugten Ausführungsform weist die Bedienblende an ihrem unteren Endabschnitt eine sich über im wesentlichen deren gesamte Breite erstreckende Blendenplatte auf, unterhalb derer ein Eingriffsraum zum Anheben des Haushaltsgerätes an der Bedienblende vorgesehen ist. Dadurch ist sichergestellt, daß eine Bedienperson die Frontblende direkt untergreifen kann, wenn sie mit Hilfe der Frontblende das Haushaltsgerät heben bzw. bewegen will. Der Eingriffsraum kann sich auch erst dann ergeben, wenn eine Tür unterhalb der Frontblende geöffnet oder demontiert ist.According to a preferred embodiment, the control panel has at its lower end section an aperture plate which extends over substantially its entire width, below which an engagement space is provided for lifting the household appliance on the control panel. This ensures that an operator can directly reach under the front panel if they want to use the front panel to lift or move the household appliance. The intervention area can also only arise if a door below the front panel is open or removed.

A built-in cooker 1 has an oven muffle, not shown, which can be closed by a door 3 at the front. To actuate the door 3, a bow-shaped door handle 5 is attached to its upper end area via two narrow webs in a manner known per se. Above the door 3, a front panel 7 extends over its entire width to form a narrow engagement space 6. This is designed as an aluminum extruded profile part. The intervention space 6 can be significantly enlarged by opening the door 3 or by dismantling it. In the upper third of the front panel 7, as is explained below, a glass plate 9 known per se is held. Control elements 11 and display elements 13, which enable operation and monitoring of built-in cooker 1 in a manner known per se, are assigned to or held in front panel 7. A printing, not shown, of the front panel 7 is protected by a very scratch-resistant anodized layer formed thereover (FIG. 1).
Die Aluminium-Frontblende 7 ist gemäß Fig. 2 an einem Blendenrahmen 15 befestigt, der aus glasfaserverstärktem PBT-Kunststoff besteht. Frontseitig ist dabei der Blendenrahmen 15 durch die Frontblende 7 und die Glasplatte 9 verdeckt also im wesentlichen nicht sichtbar. Die Frontblende 7 ist gemäß Fig. 2 und 3 mit einem Radius von etwa 3 m gleichmäßig über deren Breite zylinderwandabschnittsförmig gebogen. Ent- sprechendes gilt nach der Montage der dünnen Glasplatte 9 für diese. Auch die Tür 3 weist eine entprechende Gestalt auf. Die Frontblende 7 besitzt eine Bedienelementenplatte 17, an deren unteren Endabschnitt sich rechtwinklig davon über die gesamte Breite eine Blendenplatte 19 erstreckt. An der Blendenplatte 19 sind eine Blendenfeder 21 und eine dieser gegenüberliegende Blendennut 23 vorgesehen. Vom oberen End- abschnitt der Bedienelementenplatte 17 erstreckt sich geringfügig zurückversetzt eine Anzeigeelementenplatte 25 nach oben. In dieser und der Bedienelementenplatte 17 sind geeignete Öffnungen 27 für die Bedienelemente 11 und die Anzeigeelemente 13 vorgesehen. Weiterhin ist in der Anzeigeelementenplatte 25 frontseitig eine Dichtungsnut 29 ausgebildet, in die bei der Montage der Glasplatte 9 an der Frontblende 7 zwi- sehen beide eine nicht gezeigte Silikondichtung eingelegt wird (Fig. 3). Zur Befestigung der Glasplatte 9 werden auf deren Rückseite zwei Rastelemente (nicht gezeigt) geklebt, die mit ihren Rasthaken in in der Anzeigeelementenplatte 25 vorgesehene Rastöffnungen 31 lösbar schnappen können. Damit ist eine dichte und feste Verbindung zwischen der Frontblende 7 und der Glasplatte 9 hergestellt. Entlang des oberen Ran- des weist die Anzeigenelementenplatte 25 weiterhin rückseitig einen Schraubkanal 33 auf. Zur Befestigung eines an sich bekannten Schalterträgers (nicht gezeigt) an der Frontblende 7 wird dieser mit entsprechenden Mitteln in die Blendennut 23 eingehängt, dann an den Schraubkanal 33 gekippt und schließlich in diesem verschraubt.2, the aluminum front panel 7 is fastened to a panel frame 15 which is made of glass fiber-reinforced PBT plastic. On the front side, the panel frame 15 is essentially not visible through the front panel 7 and the glass plate 9. The front panel 7 is bent according to FIGS. 2 and 3 with a radius of about 3 m evenly across the width of the cylinder wall section. The same applies accordingly to the mounting of the thin glass plate 9. The door 3 also has a corresponding shape. The front panel 7 has an operating element plate 17, at the lower end portion of which a panel plate 19 extends at right angles across the entire width. A diaphragm spring 21 and a diaphragm groove 23 opposite this are provided on the diaphragm plate 19. A display element plate 25 extends upwards from the upper end section of the control element plate 17, set back slightly. Suitable openings 27 for the control elements 11 and the display elements 13 are provided in this and the control element plate 17. Furthermore, a seal groove 29 is formed in the front of the display element plate 25, into which a silicone seal (not shown) is inserted between the glass plate 9 on the front panel 7 (FIG. 3).

Im unteren Abschnitt ist über die gesamte Breite des Blendenrahmens 15 eine horizontal verlaufende Rahmennut 46 vorgesehen. Diese ist in einem kurzen Teilstück durch eine Aussparung 47 unterbrochen. Weiterhin sind zur Befestigung der Frontblende 7 an dem Blendenrahmen 15 Rasthaken 49 an dessen nach vorne ragender Seitenwand 51 vorgesehen (Fig. 4).The one-piece plastic screen frame 15 shown in FIG. 4 has in each side area a fastening plate 37 protruding rearward at right angles therefrom, each with two first screw openings 39 arranged one above the other. Through the first screw openings 39, the fastening screws for fastening the panel frame 15 to side walls or strips (not shown) of the housing of the built-in cooker 1 can be inserted. As a result, all the forces acting on the front panel 7 are directed into the built-in cooker 1 via these points. Therefore, the mounting plate 37 has two horizontally extending stiffening ribs 41. A second screw opening 43 for fastening the front panel 7 is formed in each of the two upper corner angles of the panel frame 15. This penetrates in each case a plate-shaped approach, which forms a first contact surface 45 of the panel frame 15 for the front panel 7. In the lower section, a horizontally extending frame groove 46 is provided over the entire width of the diaphragm frame 15. This is interrupted in a short section by a recess 47. Furthermore, locking hooks 49 are provided on the front frame 7 for fastening the front panel 7 to the front frame 15 (FIG. 4).
Die Befestigung des Blendenrahmens 15 an der Blende 7 erfolgt wie folgt: Die Frontblende 7 wird auf den Blendenrahmen 15 gesteckt. Dabei liegt die Blendenfeder 21 in der Rahmennut 46 bzw. ragt zum Teil durch die Aussparung 47. Die beiderseits am Blendenrahmen 15 vorgesehenen Rasthaken 49 schnappen in die Blendennut 33 ein. Damit sind der Blendenrahmen 15 und die Frontblende 7 über deren gesamte Breite in diesem Bereich formschlüssig miteinander verbunden, wodurch vertikal in die Frontblende 7 eingeleitete Kräfte in den durch die Frontblende 7 versteiften Blendenrahmen 15 eingeleitet werden können. Im oberen Bereich liegt die Frontblende 7 mit ihrem Schraubkanal 33 auf der ersten Anlagefläche 45 des Blendenrahmens 15. Durch nicht gezeigte Schrauben werden beide in diesem Bereich miteinander verschraubt. In den Seitenbereichen und an der Oberseite der Frontblende 7 wird diese von dem Blendenrahmen 15 umgriffen. Dessen Seitenplatte 51 schließt dabei bündig mit der Anzeigeelementenplatte 25 ab und wird durch einen jeweils seitlich an der Anzeigeelementenplatte 25 ausgebildeten Blendenansatz 53 verdeckt. Entsprechend wird die Frontblen- de 7 an ihrer Oberseite durch eine Deckplatte 55 des Blendenrahmens 15 übergriffen. Dabei entspricht der kreisabschnittförmige Verlauf der Vorderkante der Deckplatte 55 exakt dem gekrümmten Verlauf der Frontblende 7. Eine durch den gebogenen Verlauf der Frontblende 7 entstehende kreissegmentförmige Öffnung ist dadurch abgedeckt. Durch eine entsprechende Ausbildung des Blendenrahmens 15 im Bereich der Rahmennut 46 ist die entsprechende Öffnung auch in diesem Bereich abgedeckt (Fig. 5).The panel frame 15 is fastened to the panel 7 as follows: The front panel 7 is plugged onto the panel frame 15. The diaphragm spring 21 lies in the frame groove 46 or partially protrudes through the recess 47. The latching hooks 49 provided on both sides on the diaphragm frame 15 snap into the diaphragm groove 33. Thus, the panel frame 15 and the front panel 7 are positively connected to one another over their entire width in this area, as a result of which forces introduced vertically into the front panel 7 can be introduced into the panel frame 15 stiffened by the front panel 7. In the upper area, the front panel 7 with its screw channel 33 lies on the first contact surface 45 of the panel frame 15. Both are screwed together in this area by screws, not shown. In the side areas and on the top of the front panel 7, this is encompassed by the panel frame 15. Its side plate 51 closes flush with the display element plate 25 and is covered by a panel extension 53 formed on the side of the display element plate 25. Correspondingly, the front panel 7 is overlapped on its top by a cover plate 55 of the panel frame 15. The circular segment-shaped profile of the front edge of the cover plate 55 corresponds exactly the curved shape of the front panel 7. An arc segment-shaped opening created by the curved profile of the front panel 7 is thereby covered. A corresponding design of the diaphragm frame 15 in the area of the frame groove 46 also covers the corresponding opening in this area (FIG. 5).
Die Frontblende 7 ist, wie oben erläutert, zusammen mit der Glasplatte 9 an dem Blendenrahmen 15 befestigt. Dieser ist mittels durch die ersten Schrauböffnungen 39 gesteckte Schrauben jeweils seitlich an dem Einbauherdgehäuse befestigt. Dabei liegt zum einen die Außenseite der Befestigungsplatte 37 an dem Gehäuse an (nicht gezeigt). Zum anderen liegt der Blendenrahmen 15 über eine zweite Anlagefläche 67 (Fig. 5) an einem Backofenflansch 69 über im wesentlichen dessen gesamter Breite an (Fig. 6). Der Einbauherd 1 ist deckseitig durch ein an dem Blendenrahmen 15 anstehendes Deckblech 71 verschlossen. Bei der Montage wird der Einbauherd 1 soweit in eine vorhandene Einbaunische geschoben, bis eine dritte Aniagefläche 73 des Blendenrahmens 15 jeweils an die Stirnseite eines an sich bekannten Einbaumöbels 75 stößt. The front panel 7, as explained above, is attached to the panel frame 15 together with the glass plate 9. This is fastened laterally to the built-in cooker housing by means of screws inserted through the first screw openings 39. On the one hand, the outside of the fastening plate 37 bears against the housing (not shown). On the other hand, the panel frame 15 bears against a baking oven flange 69 over essentially its entire width via a second contact surface 67 (FIG. 5) (FIG. 6). The built-in cooker 1 is closed on the top side by a cover plate 71 which is in contact with the panel frame 15. During assembly, the built-in cooker 1 is pushed into an existing installation niche until a third angling surface 73 of the panel frame 15 abuts the front side of a built-in piece of furniture 75 known per se.
