Abstract

The control knob for a domestic apparatus, e.g. an oven, is intended to be designed and illuminated, as far as possible, such that the adjusting mark is clearly visible. According to the invention the rotating knob (11), which can be depressed, has a translucent annular apron (15) which surrounds the inner guide part at a distance. Behind the annular apron (15), there is located a lamp holder ring (9), fitted with small incandescent lamps (10), which pass into the annular space surrounded by the annular apron (15) when the rotating knob is depressed. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Einstellen der Schalter und Regelvorrichtungen eines Haushaltgerätes, insbesondere eines Herdes, bestehend aus einem versenk­baren Drehknebel mit zugeordneten Einstellmarkierungs­zeichen, welche von einer hinter der Schalterblende an­geordneten Beleuchtungseinrichtung besser sichtbar ge­macht werden.The invention relates to a device for setting the switches and control devices of a household appliance, in particular a cooker, consisting of a retractable rotary knob with associated setting markings, which are made more visible by a lighting device arranged behind the switch panel.

Eine solche Vorrichtung ist durch die DE-PS 23 64 667 bekannt. Bei Nichtgebrauch ist der Betätigungsknebel in eine mit der Schalterblende bündige Stellung bringbar. Auf der Schalterachse sit ein Skalenring angeordnet, welcher hinter einer Glasplatte vorbeigeführt und mittels einer Lampe von hinten beleuchtet wird, so daß die eingestellte Markierung von vorne lesbar ist. Der Gesamtaufbau ist verhältnismäßig kompliziert und die Beleuchtung reicht nicht aus, um den gesamten Skalenring gut auszuleuchten.Such a device is known from DE-PS 23 64 667. When not in use, the control knob can be brought into a position that is flush with the switch panel. A scale ring is arranged on the switch axis, which passes behind a glass plate and is illuminated from behind by means of a lamp, so that the set marking can be read from the front. The overall structure is relatively complicated and the lighting is not sufficient to illuminate the entire scale ring well.

Der Erfindung liegt die Aufgabe zugrunde eine montage­freundliche und einfache Vorrichtung zu schaffen, welche eine gut sichtbare und lesbare Skala des Drehknebels aufweist.The invention has for its object to provide an assembly-friendly and simple device which has a clearly visible and legible scale of the rotary knob.

Zur Lösung dieser Aufgabe werden die im Patentanspruch 1 angegebenen Merkmale vorgeschlagen.To achieve this object, the features specified in claim 1 are proposed.

Drehknebel und Skalenring bilden eine Baueinheit und die gesamte Vorrichtung kann auf kleinstem Raum hinter der Schalterblende untergebracht werden. Außerdem ist eine einfache aber stabile Befestigung der Regelschalter möglich.The rotary toggle and scale ring form a structural unit and the entire device can be accommodated in the smallest space behind the switch panel. In addition, a simple but stable attachment of the control switch is possible.

In der Zeichnung ist die Erfindung an einem Ausführungs­beispiel dargestellt.In the drawing, the invention is illustrated using an exemplary embodiment.

Es zeigen:

  • Fig. 1 den Schnitt durch eine Betätigungsvorrichtung in Betriebsstellung des Drehknebels und
  • Fig. 2 die Stellung bei versenkten Drehknebel,
  • Fig. 3 die Ansicht des Drehknebels in Betriebsstellung, mit Einstellmarkierungen an Stirnseite und Umfang.
Show it:
  • Fig. 1 shows the section through an actuator in the operating position of the rotary knob and
  • 2 the position with the rotary knob sunk,
  • Fig. 3 shows the view of the rotary knob in the operating position, with adjustment marks on the front and circumference.

In einen kreisförmigen Ausschnitt der Schalterblende 1 ist ein Montagetopf 2 eingesetzt, wobei der Topfrand über federnde Elemente 3 in die Schalterblende einklipst. Der Montagetopf 2 ist dadurch stabil an der Schalterblende befestigt. Ein aufsteckbarer Blendring 4 verdeckt den von vorne sichtbaren Kragen des Montagetopfes 2 und er ist farblich der Schalterblende angepaßt.A mounting pot 2 is inserted into a circular cutout of the switch panel 1, the pot rim clipping into the switch panel via resilient elements 3. The mounting pot 2 is thereby securely attached to the switch panel. An attachable cover ring 4 covers the collar of the mounting pot 2, which is visible from the front, and the color of the switch cover is adapted.

Die Steckachse 5 des schematisch angedeuteten Regel­schalters 6 ist durch die Rückwand 7 des Montagetopfes 2 gesteckt und der Regelschalter am Montagetopf stabil befestigt.The plug axis 5 of the schematically indicated control switch 6 is inserted through the rear wall 7 of the mounting pot 2 and the control switch is stably attached to the mounting pot.

Der Lampenhaltering 9 ist auf der zur Herdvorderseite weisenden Stirnfläche beispielsweise mit drei über den Umfang verteilten Glühlämpchen 10 versehen.The lamp holder ring 9 is provided, for example, with three light bulbs 10 distributed over the circumference on the end face facing the stove front.

An seiner Rückseite ist eine Leiterplatine 8 einge­klipst. An der Leiterplatine befinden sich zwei Kontaktstifte. Der Lampenhaltering, mit der Leiterplatine eine Einheit bildend, wird entlang einer nicht darge­stellten Führung in den Montagetopf 2 eingeschoben, daß die Kontaktstifte in die vorgesehenen Buschen an dem abgestuften Rückwandteil 7 des Montagetopfes greifen.A circuit board 8 is clipped onto its rear side. There are two contact pins on the circuit board. The lamp holder ring, forming a unit with the printed circuit board, is inserted into the mounting pot 2 along a guide (not shown) such that the contact pins engage in the bushes provided on the stepped rear wall part 7 of the mounting pot.

Der Drehknebel 11 ist von vorne auf die Steckachse 5 des Regelschalters 6 aufsteckbar. Hierzu dient das im Bereich der Drehachse liegende und in dem hohlzylindrischen Führungsteil 12 des Drehknebels 1 verschiebbar gelagerte Halteglied 13. Das Halteglied 13 und der Drehknebel 1 sind durch die Druckfeder 14 kraftschlüssig miteinander verbunden.The rotary toggle 11 can be plugged onto the plug axis 5 of the control switch 6 from the front. The holding member 13, which is located in the region of the axis of rotation and is displaceably mounted in the hollow cylindrical guide part 12 of the rotary toggle 1, is used. The holding member 13 and the rotary toggle 1 are non-positively connected to one another by the compression spring 14.

Um den Führungsteil 12 ist eine aus durchscheinendem Material bestehende Ringschürze 15 mit Abstand vorge­sehen. Die Ringschürze trägt auf ihrer in den Montagetopf 2 fahrenden Seitenfläche 16 die Einstellmarkierungen. Ergänzend sind vorteilhaft auf der zur Schalterblende parallel laufenden Stirnfläche 17 der Ringschürze eben­falls Einstellmarkierungen vorgesehen. In Betriebs­ stellung (Fig. 1) werden die Einstellmarkierungen durch die Glühlämpchen 10 gut ausgeleuchtet und die Einstell­stufe ist auf allen Richtungen gut ablesbar.A ring apron 15 made of translucent material is provided around the guide part 12 at a distance. The ring apron bears the setting markings on its side surface 16 moving into the mounting pot 2. In addition, setting markings are also advantageously provided on the face 17 of the ring apron that runs parallel to the switch panel. In operation position (Fig. 1), the setting marks are well illuminated by the light bulbs 10 and the setting level is easy to read in all directions.

Fig. 2 zeigt die Stellung mit versenktem Drehknebel. Die an sich bekannten Einrast- und Löseschikanen für den Drehknebel sind dabei nicht zu sehen. Es soll nur die Funktion des Drehknebels angedeutet werden. Die Ringschürze 15 ist um den Lampenhaltering 9 geschoben und die Druckfeder 14 zusammengedrückt. Wenn der Drehknebel in dieser Stellung noch etwas tiefer eingedrückt wird, löst sich der Einratmechanismus und der Drehknebel springt unter dem Federdruck in die Betriebsstellung gemäß Fig. 1.Fig. 2 shows the position with the rotary knob sunk. The known snap-in and release chicanes for the rotary knob cannot be seen. Only the function of the rotary knob should be indicated. The ring apron 15 is pushed around the lamp holder ring 9 and the compression spring 14 is compressed. If the rotary toggle is pressed in a little more deeply in this position, the engagement mechanism is released and the rotary toggle jumps into the operating position according to FIG. 1 under the spring pressure.
