Description

Gegenstand der Erfindung ist ein Haushaltsgerät gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a household appliance according to the preamble of claim 1.

Eine derartige Ausgestaltung einer Beleuchtungseinrichtung läßt sich aus DE 40 03 736 herleiten. Die Erfindung ist aber auch anwendbar für andere Haushaltgeräte, wie beispielsweise Geschirrspülmaschinen, Kühlschränke und dgl.Such a configuration of a lighting device can be derived from DE 40 03 736. However, the invention can also be used for other household appliances, such as dishwashers, refrigerators and the like.

Ansonsten war es verbreitet üblich, in das Backofengehäuse, auch Muffel genannt, Ausschnitte vorzusehen, wobei in diesen-Ausschnitten die Backofenbeleuchtung, d.h. die Lampenfassung, die Lampe, der Reflektor, das Abdeckglas und dgl. eingesetzt wurden. Die von Spezialfirmen gelieferten Lampen sind einerseits kostspielig und benötigen andererseits eine separate Schutzleiterverbindung zum Lampengehäuse, wobei der Arbeitsaufwand beträchtlich ist.Otherwise, it was common practice to provide cutouts in the oven housing, also called the muffle, the oven lighting, ie the lamp holder, the lamp, the reflector, the cover glass and the like, being used in these cutouts were. The lamps supplied by specialist companies are expensive on the one hand and on the other hand require a separate protective conductor connection to the lamp housing, the work involved being considerable.

Es ist Aufgabe der Erfindung, eine einfache und zeitsparende Backofenbeleuchtung aufzuzeigen, die weniger Arbeit- und Herstellungsaufwand aufweist.It is an object of the invention to show a simple and time-saving oven lighting which has less labor and manufacturing effort.

Ausgehend von einer bekannten Backofenbeleuchtung für Haushaltsgeräte einschließlich Mikrowellengeräte, mittels einer elektrischen Lampe und einem Reflektor, besteht die Erfindung darin, daß der in die Vertiefung der Wandung des Gehäuses lose eingesetzte und durch ein eingeklipstes Abdeckglas ansonsten befestigungslos gehaltene Reflektor federnde Ausprägungen aufweist, die beim Aufsetzen des Abdeckglases gegen die Wandungen der Vertiefung gedrückt werden. Durch diese nach der Erfindung getroffene Ausbildung des Backofengehäuses kann der Arbeitsaufwand zur Herstellung einer Beleuchtung wesentlich vereinfacht werden. Durch die beim Aufsetzen des Abdeckglases gegen die Wandungen der Vertiefung gedrückten federnden Ausprägungen am Reflektor erfährt dieser einen sicheren Sitz im Gehäuse.Starting from a known oven lighting for household appliances including microwave devices, by means of an electric lamp and a reflector, the invention consists in that the reflector, which is loosely inserted into the recess of the wall of the housing and otherwise held by a clipped-on cover glass, has resilient characteristics when it is put on of the cover glass are pressed against the walls of the recess. This design of the oven housing according to the invention considerably simplifies the work involved in producing lighting. As a result of the resilient features on the reflector pressed against the walls of the depression when the cover glass is put on, the reflector is securely seated in the housing.

Ist der Backofen beispielsweise ein Mikrowellengerät, so ist die in die Vertiefung eingesetzte Lampe mit einem Schutzgitter versehen. Die Vertiefung im Backofengehäuse kann rund, quadratisch oder rechteckig in der Wandung des Backofengehäuses geprägt sein. Ist das Gehäuse z.B. eine Geschirrspülmaschine, so empfiehlt es sich, zwischen Abdeckglas und der Wandung eine ringförmige Dichtung zu legen. Auch die Vertiefung in der Backofenmuffel bzw. im Gehäuse soll zweckmäßigerweise ebenfalls einen an sich bekannten Ausschnitt zur Durchführung des Lampensockels aufweisen. Falls es möglich ist, die Vertiefung weiträumig auszubilden, genügt es auch die Ausschnitte so klein zu halten, daß eine Kabeldurchführung zum Lampensockel ermöglicht wird.If the oven is a microwave device, for example, the lamp inserted into the recess is provided with a protective grille. The recess in the oven housing can be round, square or rectangular in the wall of the oven housing. If the housing is a dishwasher, for example, it is advisable to place an annular seal between the cover glass and the wall. Also the deepening in The oven muffle or in the housing should also expediently have a cutout known per se for the passage of the lamp base. If it is possible to make the recess large, it is also sufficient to keep the cutouts so small that a cable entry to the lamp base is made possible.

In der Zeichnung ist die Neuerung beispielsweise und schematisch dargestellt, wobei auf eine Gesamtansicht des Gehäuses verzichtet wird.In the drawing, the innovation is shown schematically, for example, without an overall view of the housing.

Wie aus der Zeichnung zu ersehen, ist mit 1 die elektrische Lampe dargestellt, welche durch einen Reflektor 2 geführt ist, wobei beide in einer Vertiefung 3 der Wandung 4, z.B. der Muffel eines Backofens gehalten sind. Der Reflektor 2 wird von innen in die Vertiefung 3 eingesetzt. Er besitzt Ausprägungen 8, wobei die federnden Zungen der Ausprägungen gegen die Vertiefung 3 der Wandung 4 lasten. Ein Abdeckglas 5 rastet in Krallen 6 der Wandung 4, wobei das Abdeckglas Gegenkrallen 6' aufweist, mit denen es an der Wandung 4 der Vertiefung 3 gehalten ist. Dabei drückt die Nase der Gegenkrallen 6' gegen den Reflektor 2 und drückt diesen in die Vertiefung 3, wobei die federnden Ausprägungen 8 den Reflektor in der Vertiefung einen festen Sitz verleihen. Es ist möglich - hier nicht dargestellt - zwischen Abdeckglas 5 und der Wandung 4 noch eine ringförmige Dichtung einzulegen. Es empfiehlt sich z.B. bei Mikrowellengeräten die Lampe 1 noch mit einem Schutzgitter 7 zu umgeben. Das Schutzgitter kann über die Glühlampe 1 gesteckt werden.As can be seen from the drawing, 1 shows the electric lamp which is guided through a reflector 2, both of which are held in a recess 3 in the wall 4, for example the muffle of an oven. The reflector 2 is inserted into the recess 3 from the inside. It has features 8, the resilient tongues of the features against the recess 3 of the wall 4. A cover glass 5 snaps into claws 6 of the wall 4, the cover glass having counter-claws 6 'with which it is held on the wall 4 of the recess 3. The nose of the counter claws 6 'presses against the reflector 2 and presses it into the recess 3, the resilient features 8 giving the reflector a firm fit in the recess. It is possible - not shown here - to insert an annular seal between cover glass 5 and wall 4. It is advisable, for example in microwave devices, to surround lamp 1 with a protective grille 7. The protective grille can be placed over the light bulb 1.

Bei dieser Ausbildung ist der Bezug teurer, eigenständig eine Einheit bildenden Lampen nicht mehr erforderlich. Ebenfalls wird eine separate Schutzleiterverbindung zum Lampengehäuse nicht mehr benötigt. Spezielle Verschraubungen entfallen.With this training, it is no longer necessary to purchase expensive lamps that independently form a unit. A separate protective conductor connection to the lamp housing is also no longer required. Special screw connections are not required.

Claims (3)
