- Such a rotary toggle is out DE 10 2005 032 509 B4 famous.
- This rotary toggle has a fastening part made of plastic, which is designed as a light guide that transmits light from a light source from inside the household appliance to a display part on the outside of the household appliance.
- the attachment part also contains attachment means for attaching the light source.
- a disadvantage of the solution described is the complicated structure and also the non-uniform illumination of the display part by the light source.

- the circuit board in the base enables simple prefabrication by automatically arranging the light-emitting diode on the circuit board. This means that only the prefabricated circuit board has to be inserted into the base and the light guide arranged on the circuit board when assembling the rotary knob.
- the light guide also directs the light to a ring of light surrounding the knob, so that the knob is evenly illuminated. This simplifies the handling of the rotary toggle even when the ambient light is weak and also enables a simple yet visually appealing configuration of the rotary toggle.
- the circuit board has a plurality of light-emitting diodes in the base, with the light guide having a plurality of luminous channels which guide the light of the luminous diodes into the luminous ring.
- the plurality of light-emitting diodes are preferably distributed uniformly on the circular arc of the light ring.
- the light from the plurality of light-emitting diodes is preferably conducted into the luminous ring via a plurality of luminous channels of the light guide, so that a uniform distribution on the circular arc of the luminous ring can be achieved.
- An embodiment is particularly preferred which provides that the light channels guide the light of the light emitting diodes along an axis of rotation of the knob and deflect it tangentially into the light ring surrounding the axis of rotation. With the deflection of the light from the emission direction of the light-emitting diodes along an axis of rotation of the knob towards a tangential introduction of the Light in the luminous ring surrounding the axis of rotation, a particularly uniform illumination of the luminous ring can be achieved by the light-emitting diodes arranged on the circuit board.
- a particularly advantageous embodiment of the invention relates to the fact that the light channels distribute the light uniformly on the circular arc of the light ring into the light ring.
- a particularly uniform illumination of the luminous ring and thus the knob is achieved by the evenly distributed introduction of the light from the luminous channels into the circular arc of the luminous ring.
- each light-emitting diode is assigned a single light channel, which deflects the light emitted by the assigned light-emitting diode individually into the light ring and the light from the light-emitting diodes combined in this way illuminates the entire light ring completely surrounding the knob.
- the light emitted by the plurality of light-emitting diodes is therefore brought together in the light-emitting ring via the light-emitting channels each assigned to a light-emitting diode.
- the loss of light due to reflections and refractions is low due to the individual deflection of the light from each light-emitting diode, so that a high light intensity can be achieved in the light ring illuminated jointly by the light-emitting diodes.
- the assignment of a single light channel to a single light-emitting diode ensures that the light ring is illuminated with as little loss as possible, since the light from the light-emitting diode assigned to the light channel can be deflected with low losses due to reflections and refractions via the individual deflection in the respective light channel. In this way, a particularly uniform illumination of the luminous ring that completely surrounds the knob can be achieved.
- a particularly advantageous embodiment of the invention provides at least one detent mechanism, which is designed to haptically detent the knob in several ways when the knob rotates relative to the base to effect detents.
- the user receives feedback via the tactile clicks of the knob when operating the kitchen appliance using the rotary knob, which makes handling the rotary knob easier.
- the locking mechanism When the knob rotates in relation to the base, the locking mechanism generates haptic feedback as the knob engages in different locking positions.
- the circuit board has a counter which is designed to count the haptic detents of the detent mechanism, the circuit board comprising a computing unit which is designed to convert the detents of the detent mechanism counted by the counter into operating signals for operation of the kitchen appliance.
- the circuit board has a counter which is designed to count the haptic detents of the detent mechanism, the circuit board comprising a computing unit which is designed to convert the detents of the detent mechanism counted by the counter into operating signals for operation of the kitchen appliance.

Es ist daher Aufgabe der Erfindung, einen verbesserten Drehknebel anzugeben, der einen einfacheren und günstigeren Aufbau, eine schnellere Montage und eine gleichmäßigere Ausleuchtung ermöglicht.It is therefore the object of the invention to specify an improved rotary toggle which enables a simpler and more economical design, faster assembly and more uniform illumination.
Gelöst wird diese Aufgabe durch einen Drehknebel mit den Merkmalen des Anspruchs 1.This problem is solved by a rotary toggle with the features of
Mit einer Platine im Sockel, die wenigstens eine Licht emittierende Leuchtdiode aufweist, wobei an der Platine im Sockel ein Lichtleiter angeordnet ist, der das Licht der Leuchtdiode zu einem den Knauf umgebenden Leuchtring des Sockels leitet, kann ein einfacher und günstiger Aufbau des Drehknebels sowie eine schnelle Montage und eine gleichmäßigere Ausleuchtung ermöglicht werden. Die Platine im Sockel ermöglicht eine einfache Vorfertigung durch automatische Anordnung der Licht emittierenden Leuchtdiode auf der Platine. Damit muss bei der Montage des Drehknebels lediglich die vorgefertigte Platine in den Sockel eingesetzt werden und der Lichtleiter an der Platine angeordnet werden. Der Lichtleiter leitet das Licht zudem zu einem den Knauf umgebenden Leuchtring, sodass der Knauf gleichmäßig ausgeleuchet wird. Dies vereinfacht die Handhabung des Drehknebels auch bei schwachem Umgebungslicht und ermöglicht auch eine einfache und dennoch optisch ansprechende Ausgestaltung des Drehknebels.With a circuit board in the base, which has at least one light-emitting diode, a light guide being arranged on the circuit board in the base, which directs the light from the light-emitting diode to a luminous ring of the base surrounding the knob directs, a simpler and cheaper construction of the rotary knob as well as a quick installation and a more even illumination can be made possible. The circuit board in the base enables simple prefabrication by automatically arranging the light-emitting diode on the circuit board. This means that only the prefabricated circuit board has to be inserted into the base and the light guide arranged on the circuit board when assembling the rotary knob. The light guide also directs the light to a ring of light surrounding the knob, so that the knob is evenly illuminated. This simplifies the handling of the rotary toggle even when the ambient light is weak and also enables a simple yet visually appealing configuration of the rotary toggle.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen. Es ist darauf hinzuweisen, dass die in den Ansprüchen einzeln aufgeführten Merkmale auch in beliebiger und technologisch sinnvoller Weise miteinander kombiniert werden können und somit weitere Ausgestaltungen der Erfindung aufzeigen.Advantageous refinements and developments of the invention result from the dependent claims. It should be pointed out that the features listed individually in the claims can also be combined with one another in any technologically meaningful manner and thus show further refinements of the invention.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Platine im Sockel mehrere Licht emittierende Leuchtdioden aufweist, wobei der Lichtleiter mehrere Leuchtkanäle aufweist, die das Licht der Leuchtdioden in den Leuchtring leiten. Mit mehreren Licht emittierenden Leuchtdioden kann die Ausleuchtung des Leuchtrings stärker und gleichmäßiger erfolgen. Hierzu sind die mehreren Leuchtdioden bevorzugt gleichmäßig auf dem Kreisbogen des Leuchtrings verteilt angeordnet. Das Licht der mehreren Leuchtdioden wird zur gleichmäßigeren Ausleuchtung des Leuchtrings bevorzugt über mehrere Leuchtkanäle des Lichtleiters in den Leuchtring geleitet, sodass eine gleichmäßige Verteilung auf dem Kreisbogen des Leuchtrings erreicht werden kann.According to an advantageous embodiment of the invention, it is provided that the circuit board has a plurality of light-emitting diodes in the base, with the light guide having a plurality of luminous channels which guide the light of the luminous diodes into the luminous ring. With several light-emitting LEDs, the illumination of the light ring can be stronger and more even. For this purpose, the plurality of light-emitting diodes are preferably distributed uniformly on the circular arc of the light ring. For more uniform illumination of the luminous ring, the light from the plurality of light-emitting diodes is preferably conducted into the luminous ring via a plurality of luminous channels of the light guide, so that a uniform distribution on the circular arc of the luminous ring can be achieved.
Besonders bevorzugt ist eine Ausführungsform, die vorsieht, dass die Leuchtkanäle das Licht der Leuchtdioden entlang einer Drehachse des Knaufs leiten und tangential in den die Drehachse umgebenden Leuchtring umlenken. Mit der Umlenkung des Lichts von der Abstrahlrichtung der Leuchtdioden entlang einer Drehachse des Knaufs hin zu einer tangentialen Einleitung des Lichts in den die Drehachse umgebenden Leuchtring kann eine besonders gleichmäßige Ausleuchtung des Leuchtrings durch die auf der Platine angeordneten Leuchtdioden erreicht werden.An embodiment is particularly preferred which provides that the light channels guide the light of the light emitting diodes along an axis of rotation of the knob and deflect it tangentially into the light ring surrounding the axis of rotation. With the deflection of the light from the emission direction of the light-emitting diodes along an axis of rotation of the knob towards a tangential introduction of the Light in the luminous ring surrounding the axis of rotation, a particularly uniform illumination of the luminous ring can be achieved by the light-emitting diodes arranged on the circuit board.
Eine besonders vorteilhafte Ausführung der Erfindung bezieht sich darauf, dass die Leuchtkanäle das Licht auf dem Kreisbogen des Leuchtrings gleichmäßig verteilt in den Leuchtring leiten. Über die gleichmäßig verteilte Einleitung des Lichts aus den Leuchtkanälen in den Kreisbogen des Leuchtrings wird eine besonders gleichmäßige Ausleuchtung des Leuchtrings und damit des Knaufs erreicht.A particularly advantageous embodiment of the invention relates to the fact that the light channels distribute the light uniformly on the circular arc of the light ring into the light ring. A particularly uniform illumination of the luminous ring and thus the knob is achieved by the evenly distributed introduction of the light from the luminous channels into the circular arc of the luminous ring.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass jeder Leuchtdiode ein einzelner Leuchtkanal zugeordnet ist, der das von der zugeordneten Leuchtdiode emittierte Licht einzeln in den Leuchtring umlenkt und das so kombinierte Licht der Leuchtdioden hier gemeinsam den gesamten, den Knauf vollständig umgebenden Leuchtring ausleuchtet. Es wird also über die jeweils einer Leuchtdiode zugeordneten Leuchtkanäle das von den mehreren Leuchtdioden emittierte Licht in dem Leuchtring zusammengeführt. Mit der Zuordnung eines einzelnen Leuchtkanals zu jeder Leuchtdiode kann ein Großteil des von der Leuchtdiode emittierten Lichts in den Leuchtring umgelenkt werden. Die Verluste an Licht aufgrund von Reflexionen und Brechungen ist durch die einzelne Umlenkung des Lichts jeder Leuchtdiode gering, sodass eine große Lichtintensität in dem gemeinsam von den Leuchtdioden ausgeleuchteten Leuchtring erreicht werden kann. Die Zuordnung eines einzelnen Leuchtkanals zu einer einzelnen Leuchtdiode sorgt für eine möglichst verlustfreie Ausleuchtung des Leuchtrings, da über die einzelne Umlenkung in dem jeweiligen Leuchtkanal das Licht der dem Leuchtkanal zugeordneten Leuchtdiode mit geringen Verlusten durch Reflexionen und Brechungen umgelenkt werden kann. Damit kann eine besonders gleichmäßige Ausleuchtung des den Knauf vollständig umgebenden Leuchtrings erreicht werden.According to an advantageous embodiment of the invention, each light-emitting diode is assigned a single light channel, which deflects the light emitted by the assigned light-emitting diode individually into the light ring and the light from the light-emitting diodes combined in this way illuminates the entire light ring completely surrounding the knob. The light emitted by the plurality of light-emitting diodes is therefore brought together in the light-emitting ring via the light-emitting channels each assigned to a light-emitting diode. With the assignment of an individual light channel to each light-emitting diode, a large part of the light emitted by the light-emitting diode can be deflected into the light ring. The loss of light due to reflections and refractions is low due to the individual deflection of the light from each light-emitting diode, so that a high light intensity can be achieved in the light ring illuminated jointly by the light-emitting diodes. The assignment of a single light channel to a single light-emitting diode ensures that the light ring is illuminated with as little loss as possible, since the light from the light-emitting diode assigned to the light channel can be deflected with low losses due to reflections and refractions via the individual deflection in the respective light channel. In this way, a particularly uniform illumination of the luminous ring that completely surrounds the knob can be achieved.
Eine besonders vorteilhafte Ausführung der Erfindung sieht wenigstens ein Rastwerk vor, welches dazu ausgebildet ist bei Drehbewegungen des Knaufs gegenüber dem Sockel haptische Rastungen des Knaufs in mehreren Raststellungen zu bewirken. Über die haptischen Rastungen des Knaufs erhält der Benutzer eine Rückmeldung bei der Bedienung des Küchengerätes über den Drehknebel, welche die Handhabung des Drehknebels erleichtert. Bei der Drehbewegung des Knaufs gegenüber dem Sockel erzeugt das Rastwerk haptische Rückmeldungen durch das Einrasten des Knaufs in verschiedenen Raststellungen.A particularly advantageous embodiment of the invention provides at least one detent mechanism, which is designed to haptically detent the knob in several ways when the knob rotates relative to the base to effect detents. The user receives feedback via the tactile clicks of the knob when operating the kitchen appliance using the rotary knob, which makes handling the rotary knob easier. When the knob rotates in relation to the base, the locking mechanism generates haptic feedback as the knob engages in different locking positions.
Eine vorteilhafte Ausführung der Erfindung sieht vor, dass die Platine ein Zählwerk aufweist, welches dazu ausgebildet ist, die haptischen Rastungen des Rastwerks zu zählen, wobei die Platine eine Recheneinheit umfasst, die dazu ausgebildet ist die vom Zählwerk gezählten Rastungen des Rastwerks in Bediensignale zur Bedienung des Küchengerätes umzusetzen. Mit dem Zählwerk können die einzelnen Rastungen des Rastwerks bei der Drehbewegung des Knaufs einfach gezählt werden. Aus den gezählten Rastungen können dann von einer Recheneinheit der Platine Bediensignale zur Bedienung des Küchengerätes schnell umgesetzt werden.An advantageous embodiment of the invention provides that the circuit board has a counter which is designed to count the haptic detents of the detent mechanism, the circuit board comprising a computing unit which is designed to convert the detents of the detent mechanism counted by the counter into operating signals for operation of the kitchen appliance. With the counter, the individual detents of the detent mechanism can be easily counted when the knob is turned. From the counted detents, operating signals for operating the kitchen appliance can then be quickly implemented by a computing unit on the circuit board.
Besonders vorteilhaft ist eine Ausführungsform, die vorsieht, dass der Knauf an einem beweglichen Teil des Rastwerks verklebt ist, während ein anderer Teil des Rastwerks unbeweglich mit dem Sockel verschraubt ist. Mit der Verklebung des Knaufs an dem beweglichen Teil des Rastwerks ist eine einfache Befestigung des Knaufs möglich. Da der andere Teil des Rastwerks unbeweglich in dem Sockel verschraubt ist, dient das Rastwerk zur Lagerung und Führung des Knaufes gegenüber dem Sockel. Das Rastwerk des Drehknebels sorgt somit für die drehbewegliche Verbindung und Lagerung zwischen dem Sockel und dem Knauf.An embodiment that provides that the knob is glued to a movable part of the locking mechanism, while another part of the locking mechanism is screwed immovably to the base, is particularly advantageous. By gluing the knob to the movable part of the locking mechanism, the knob can be easily attached. Since the other part of the latching mechanism is screwed immovably into the base, the latching mechanism serves to support and guide the knob relative to the base. The locking mechanism of the rotary toggle thus ensures the rotatable connection and storage between the base and the knob.
Eine vorteilhafte Ausgestaltung sieht vor, dass die Schrauben zur Verschraubung des Rastwerks an dem Sockel die Platine durchragen und diese zwischen Rastwerk und Sockel festlegen. Über diese Schrauben kann sehr einfach sowohl das Rastwerk als auch die Platine in dem Sockel festgelegt werden. Damit ist eine sehr einfache und schnelle Montage des Drehknebels in der Fertigung möglich.An advantageous embodiment provides that the screws for screwing the latching mechanism to the base protrude through the circuit board and fix it between the latching mechanism and the base. Both the locking mechanism and the circuit board can be fixed very easily in the base using these screws. A very simple and quick assembly of the rotary knob in production is thus possible.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Rastwerk neben Drehbewegungen des Knaufs um eine Drehachse des Knaufs auch axiale Druckbewegungen des Knaufs in Richtung der Drehachse zulässt. Die axialen Druckbewegungen des Benutzers auf den Knauf kann bei Entlastung des Knaufs eine entgegengesetzte Rückfederung zur Folge haben. Damit kann der Knauf durch axiale Druckbewegungen entlang der Drehachse verlagert werden und nimmt vorteilhafterweise anschließend wieder eine axiale Ausgangsposition ein.According to an advantageous embodiment of the invention, it is provided that the locking mechanism allows not only rotary movements of the knob about a rotary axis of the knob but also axial pressure movements of the knob in the direction of the rotary axis. The user's axial pressure movements on the knob can result in opposite springback when the knob is relieved. The knob can thus be displaced along the axis of rotation by axial pressure movements and then advantageously assumes an initial axial position again.
Besonders vorteilhaft ist eine Ausführungsform, die vorsieht, dass die Platine einen Sensor aufweist, welcher dazu ausgebildet ist, die axialen Druckbewegungen zu erfassen, wobei die Platine eine Recheneinheit umfasst, die dazu ausgebildet ist, die von dem Sensor erfassten Druckbewegungen in Bediensignale zur Bedienung des Küchengerätes umzusetzen. Über den Sensor kann so die Bedienung des Küchengerätes über den Knauf des Drehknebels noch vielfältiger ausgestaltet werden, da neben den Drehbewegungen auch vom Benutzer auf den Knauf ausgeübte Druckbewegungen zur Bedienung eines Küchengerätes genutzt werden können.An embodiment is particularly advantageous that provides that the circuit board has a sensor which is designed to detect the axial pressure movements, wherein the circuit board comprises a computing unit that is designed to convert the pressure movements detected by the sensor into operating signals for operating the implement kitchen appliances. Using the sensor, the operation of the kitchen appliance via the knob of the rotary knob can be designed in an even more diverse manner, since in addition to the rotary movements, pressure movements exerted by the user on the knob can also be used to operate a kitchen appliance.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass der Leuchtring radial von einem lichtundurchlässigen Zierring umgeben ist, wodurch die Abstrahlung des Lichts durch den Leuchtring axial zur Drehachse des Knaufs erfolgt. Über den Zierring kann sehr einfach die Abstrahlung des Lichts durch den Leuchtring axial zur Drehachse des Knaufs geleitet werden, sodass das abgestrahlte Licht entlang einer Grifffläche an einem Zylindermantel des Knaufs geleitet wird. Dadurch kann die Grifffläche besonders gleichmäßig ausgeleuchtet werden, sodass der Knauf auch bei schwachem Umgebungslicht gut zu erkennen und zu bedienen ist.According to a preferred embodiment of the invention, it is provided that the luminous ring is surrounded radially by an opaque decorative ring, as a result of which the light is emitted through the luminous ring axially to the axis of rotation of the knob. The emission of light through the luminous ring can very easily be guided axially to the axis of rotation of the knob via the decorative ring, so that the emitted light is guided along a gripping surface on a cylinder jacket of the knob. As a result, the grip surface can be illuminated particularly evenly, so that the knob is easy to see and operate even in poor ambient light.
Eine vorteilhafte Ausführung der Erfindung sieht vor, dass der Zierring über mindestens einen Bajonettverschluss an dem Sockel manuell lösbar befestigt ist. Der Zierring kann auch nach dem Einsetzen des Drehknebels in eine Küchengerätefront und/oder Küchenmöbelblende einfach über den Knebel geschoben werden. Mittels des Bajonettverschlusses wird dann der Zierring an dem Sockel fixiert. So kann der Zierring bei Beschädigungen zur Erneuerung oder zur Reinigung einfach per Hand montiert und demontiert werden.An advantageous embodiment of the invention provides that the decorative ring is attached to the base in a manually detachable manner via at least one bayonet catch. The decorative ring can also be simply pushed over the toggle after the rotary toggle has been inserted into a kitchen appliance front and/or kitchen furniture panel. The decorative ring is then attached using the bayonet catch fixed to the base. In the event of damage, the decorative ring can be easily assembled and disassembled by hand for replacement or cleaning.
Besonders vorteilhaft ist eine Ausführungsform, die vorsieht, dass der Sockel über einen am Sockel verschraubbaren Sockelhaltering in einer Öffnung einer Gerätefront und/oder Möbelblende festlegbar ist. Über diesen Sockelhaltering lässt sich der Drehknebel einfach mit dem Sockel in einer Öffnung einer Gerätefront und/oder Möbelblende montieren. Hierzu wird der Sockelhaltering einfach nach dem Durchstecken des Sockels durch die Öffnung auf der gegenüberliegenden Seite der Gerätefront und/oder Möbelblende auf den Sockel aufgeschraubt.An embodiment is particularly advantageous which provides that the base can be fixed in an opening of a device front and/or furniture panel by means of a base retaining ring that can be screwed to the base. Using this base retaining ring, the rotary toggle can be easily mounted with the base in an opening in a device front and/or furniture panel. To do this, the base retaining ring is simply screwed onto the base after pushing the base through the opening on the opposite side of the device front and/or furniture panel.

Die vergrößerte Darstellung des Lichtleiters 6 macht die Ausgestaltung der Leuchtkanäle 8 deutlich. Die Leuchtkanäle 8 leiten das Licht der Leuchtdioden 5 entlang der Drehachse 9 des Knaufs 2 und lenken das Licht dann tangential in den die Drehachse 9 umgebenden Leuchtring 7 um, der hier durch den Kreisring 21 des Lichtleiters 6 zu erkennen ist. Die Leuchtkanäle 8 sind bei Montage des Drehknebels 1 auf den Leuchtdioden 5 aufgesetzt und leiten das Licht auf dem Kreisring 21 des Lichtleiters 6 gleichmäßig verteilt in den Leuchtring 7 ein. Damit ist besonders einfach eine sehr gleichmäßige Ausleuchtung des Leuchtrings 7 erreichbar. Wie in
