Description

Die Erfindung betrifft einen Drehregler für ein Haushaltsgerät, aufweisend mehrere durchgängig einstellbare Schaltstellungen. Die Erfindung betrifft ferner ein Haushaltsgerät, insbesondere Kochgerät, mit mindestens einem solchen Drehregler.The invention relates to a rotary controller for a household appliance, comprising a plurality of switch positions which can be set throughout. The invention further relates to a household appliance, in particular a cooking appliance, with at least one such control dial.

Es ist ein Haushaltskochgerät (d.h. ein Haushaltsgerät mit einem Kochfeld, z.B. ein Herd oder ein eigenständiges Kochfeld) der betreffend genannten Art mit einem Drehregler bekannt, welcher ausgehend von einer Neutralstellung über mehrere Kochstufenstellungen durchstellbar ist. An die Kochstufenstellungen schließt sich eine Zonenzuschaltstellung an, welche aus der höchsten Kochstufenstellung erreichbar ist. Mit Loslassen des Drehreglers kehrt dieser selbsttätig aus der Zonenzuschaltstellung in die höchste Kochstufenstellung zurück. Die Zonenzuschaltstellung ist also eine rückspringende Schaltstellung. Benachbart zu der Zonenzuschaltstellung befindet sich die Neutralstellung, jedoch kann zwischen diesen beiden Stellungen nicht durchgeschaltet werden. Die Zonenzuschaltstellung stellt folglich eine Endstellung dar. Die Einrichtung der Zonenzuschaltstellung als Endstellung soll verhindern, dass die Kochzone nach Aktivierung oder Deaktivierung der Zonenzuschaltung unbeabsichtigt ausgeschaltet wird.A household cooking appliance (i.e. a household appliance with a cooktop, e.g. a stove or an independent cooktop) of the type mentioned with a rotary control is known, which can be set up from a neutral position over several cooking level positions. The heat setting positions are followed by a zone switch position, which can be reached from the highest heat setting. When you release the control dial, it automatically returns from the zone switch-on position to the highest heat setting. The zone switching position is therefore a recessed switching position. The neutral position is adjacent to the zone switch-on position, but it is not possible to switch between these two positions. The zone switch position thus represents an end position. The establishment of the zone switch position as the end position is intended to prevent the cooking zone from being inadvertently switched off after activation or deactivation of the zone switch.

DE 10 2005 057083 A1 offenbart einen Drehregler für ein Kochgerät, mit Zonenzuschaltstellung.. DE 10 2005 057083 A1 discloses a control knob for a cooking appliance, with zone switch-on position.

Es ist die Aufgabe der vorliegenden Erfindung, eine verbesserte Handhabung eines Haushaltsgeräts, insbesondere Kochgeräts, mit einem Drehregler, insbesondere mit einer rückspringenden Schaltstellung, bereitzustellen.It is the object of the present invention to provide improved handling of a household appliance, in particular a cooking appliance, with a rotary regulator, in particular with a recessed switching position.

Diese Aufgabe wird gemäß den Merkmalen der unabhängigen Ansprüche gelöst. Bevorzugte Ausführungsformen sind insbesondere den abhängigen Ansprüchen entnehmbar.This object is achieved in accordance with the features of the independent claims. Preferred embodiments can be found in particular in the dependent claims.

Die Aufgabe wird gelöst durch einen Drehregler für ein Haushaltsgerät, aufweisend mehrere durchgängig einstellbare Schaltstellungen, wobei zwischen zwei vorbestimmten benachbarten Schaltstellungen ein höchster Drehwiderstand vorhanden ist. Der höchste Drehwiderstand ist also insbesondere höher als alle Drehwiderstände zwischen anderen benachbarten Schaltstellungen.The object is achieved by a rotary controller for a household appliance, having a plurality of switch positions which can be set throughout, a maximum rotational resistance being present between two predetermined adjacent switch positions. The highest rotational resistance is therefore in particular higher than all the rotational resistances between other adjacent switching positions.

Mittels dieses Drehreglers wird es ermöglicht, zwischen allen Drehstellungen durchzustellen, aber einem Bediener dennoch eine ausreichende haptische Rückmeldung zu geben, welche ein unbeabsichtigtes Verdrehen des Drehreglers zwischen diesen beiden vorbestimmten Drehstellungen zu vermeiden hilft. Auf eine Ausbildung der vorbestimmten Drehstellungen als Endstellungen kann also verzichtet werden. In anderen Worten kann also ein unbeabsichtigtes Weiterdrehen zwischen diesen vorbestimmten Drehstellungen vermieden werden, aber ein bewusstes Weiterdrehen (mit erhöhter Kraft) ermöglicht werden. Dies erhöht eine Bedienflexibilität, ohne eine Betriebssicherheit oder einen Bedienkomfort zu verringern.By means of this rotary controller it is possible to switch through between all rotary positions, but nevertheless to give an operator sufficient haptic feedback which helps to prevent the rotary controller from being inadvertently rotated between these two predetermined rotary positions. There is therefore no need to design the predetermined rotational positions as end positions. In other words, an unintentional further rotation between these predetermined rotational positions can be avoided, but a conscious further rotation (with increased force) can be made possible. This increases operating flexibility without reducing operational reliability or ease of use.

Dem höchsten Drehwiderstand entspricht insbesondere ein höchstes Drehmoment, welches aufgebracht werden muss, um den Drehwiderstand zu überwinden und den Drehregler in die nächste vorbestimmte Schaltstellung zu überführen.The highest torque resistance corresponds in particular to a maximum torque which has to be applied in order to overcome the torque resistance and to move the rotary controller into the next predetermined switching position.

Es ist eine Ausgestaltung, dass eine der zwei vorbestimmten Schaltstellungen eine rückspringende Schaltstellung ist. Da zwischen den beiden vorbestimmten Schaltstellungen der höchste Drehwiderstand vorhanden ist, springt der Drehregler aus der rückspringenden vorbestimmten Schaltstellung in eine dazu benachbarte Schaltstellung zurück, welche keine der beiden vorbestimmten Schaltstellungen entspricht und also der anderen vorbestimmten Schaltstellung entgegengesetzt ist. Diese Ausgestaltung weist den Vorteil auf, dass eine rückspringende Schaltstellung mit der Möglichkeit einer Überdrehung in die andere vorbestimmte Schaltstellung realisierbar ist, bei welcher dennoch eine Gefahr eines unbeabsichtigten Überdrehens erheblich reduziert ist.It is an embodiment that one of the two predetermined switching positions is a recessed switching position. Since the highest rotational resistance is present between the two predetermined switching positions, the rotary controller jumps back from the returning predetermined switching position to an adjacent switching position which does not correspond to either of the two predetermined switching positions and is therefore opposite to the other predetermined switching position. This embodiment has the advantage that a recessed switching position can be realized with the possibility of over-rotation into the other predetermined switching position, in which the risk of unintentional over-rotation is nevertheless considerably reduced.

Es ist noch eine Ausgestaltung, dass zwischen anderen Drehstellungen ein gleicher, geringerer Drehwiderstand vorhanden ist. So wird ein haptischer Unterschied zwischen den geringeren Drehwiderständen und dem höchsten Drehwiderstand hervorgehoben und eine Wahrscheinlichkeit einer Fehlbedienung noch weiter reduziert. Dem geringeren Drehwiderstand entspricht insbesondere ein geringeres Drehmoment als das höchste Drehmoment, um den geringeren Drehwiderstand zu überwinden.It is also an embodiment that the same, lower rotational resistance is present between other rotational positions. This highlights a haptic difference between the lower rotational resistance and the highest rotational resistance and further reduces the likelihood of incorrect operation. The lower rotational resistance corresponds in particular to a lower torque than the highest torque in order to overcome the lower rotational resistance.

Es ist eine alternative Ausgestaltung, dass zwischen den anderen Drehstellungen kein Drehwiderstand vorhanden ist. So lässt sich ein haptischer Unterschied zu dem höchsten Drehwiderstand besonders hervorheben. Zwischen diesen anderen Drehstellungen lässt sich also kontinuierlich durchdrehen.It is an alternative embodiment that there is no rotational resistance between the other rotational positions. This makes a haptic difference to the highest Emphasize the turning resistance. It is therefore possible to continuously spin between these other rotational positions.

Es ist ferner eine Ausgestaltung, dass der höchste Drehwiderstand einem Drehmoment von weniger als 200 Ncm bzw. 2 Nm entspricht, insbesondere von nicht mehr als 150 Ncm bzw. 1,5 Nm. So wird ein gewünschtes Drehen des Drehreglers zwischen den beiden vorbestimmten Drehstellungen nicht übermäßig behindert.It is also an embodiment that the highest rotational resistance corresponds to a torque of less than 200 Ncm or 2 Nm, in particular not more than 150 Ncm or 1.5 Nm. In this way, a desired rotation of the rotary control between the two predetermined rotary positions is not excessively impeded.

Die Aufgabe wird auch gelöst durch ein Haushaltsgerät mit mindestens einem Drehregler wie oben beschrieben. Das Haushaltsgerät kann analog zu dem Drehregler ausgestaltet sein und entsprechende Vorteile aufweisen.The object is also achieved by a household appliance with at least one rotary control as described above. The household appliance can be designed analogously to the rotary controller and have corresponding advantages.

Es ist eine Ausgestaltung, dass das Haushaltsgerät ein Kochgerät ist und der Drehregler ein Kochzonenschalter ist. Der Kochzonenschalter kann insbesondere ein Schalter sein, mittels dessen Betriebsparameter einer Kochzone (wie Kochstufen, eine Zonenzuschaltung usw.) einstellbar sind. Der Kochzonenschalter weist insbesondere eine Neutralstellung auf, bei welcher die zugehörige Kochzone deaktiviert ist.It is an embodiment that the household appliance is a cooking appliance and the control dial is a cooking zone switch. The cooking zone switch can in particular be a switch by means of which the operating parameters of a cooking zone (such as cooking levels, a zone activation, etc.) can be set. The cooking zone switch has, in particular, a neutral position in which the associated cooking zone is deactivated.

Es ist noch eine Ausgestaltung, dass die vorbestimmten zwei Schaltstellungen, zwischen denen der höchste Drehwiderstand vorhanden ist, einer Neutralstellung und einer Zonenzuschaltstellung entsprechen. Also kann vor einem ungewollten Umschalten zwischen diesen Stellungen haptisch gewarnt werden, ohne das Umschalten zwangsweise zu verhindern.It is another embodiment that the predetermined two switching positions, between which the highest rotational resistance is present, correspond to a neutral position and a zone switching position. So you can be warned against an unwanted switch between these positions without forcibly preventing the switch.

Es ist noch eine weitere Ausgestaltung, dass die anderen Drehstellungen Kochstufen-schaltstellungen entsprechen. Insbesondere wird also ein Drehregler ermöglicht, bei dem in einer Drehrichtung (z.B. im Uhrzeigersinn) die Neutralstellung, mehrere Kochstufen-Schaltstellungen mit aufsteigendem Wert der Kochstufe (z.B. zwischen "1" als der kleinsten Kochstufe und "9" als der höchsten Kochstufe) und dann eine Zonenzuschaltstellung aufeinander folgen. Auf die Zonenzuschaltstellung folgt wieder die Neutralstellung.It is yet another embodiment that the other rotary positions correspond to the cooking stage switching positions. In particular, a rotary control is made possible in which the neutral position in one direction of rotation (e.g. clockwise), several heat setting positions with increasing value of the heat setting (e.g. between "1" as the smallest heat setting and "9" as the highest heat setting) and then one zone switch position follow each other. The zone switch position is followed by the neutral position.

Es ist ferner eine Ausgestaltung, dass die Zonenzuschaltstellung eine rückspringende Schaltstellung ist, welche auf eine benachbarte höchste Kochstufen-Schaltstellung zurückspringen kann. Insbesondere mag also zur Umschaltung zwischen der Neutralstellung und den Kochstufen-Schaltstellungen ein erster, gleicher Drehwiderstand überwunden oder ein erstes, gleiches Drehmoment aufgebracht werden. Bei Übergang von der höchsten Kochstufen-Schaltstellung in die Zonenzuschaltstellung wird dann, wenn das dazu verwendete Drehmoment ausreicht, den höchsten Drehwiderstand zu überwinden, in die Neutralstellung weitergedreht, der Drehregler also in die Neutralstellung überdreht. Wird hingegen der höchste Drehwiderstand nicht überwunden und der Drehregler losgelassen, kehrt der Drehregler in die höchste Kochstufen-Schaltstellung zurück.It is also an embodiment that the zone switching position is a recessed switching position, which can spring back to an adjacent highest cooking level switching position. In particular, like to switch between the neutral position and a first, identical rotational resistance is overcome or the first, identical torque is applied to the cooking stage switching positions. When changing from the highest cooking setting to the zone switch-on position, if the torque used is sufficient to overcome the highest rotational resistance, the knob is turned to the neutral position, i.e. the knob is turned to the neutral position. If, however, the highest rotary resistance is not overcome and the rotary control is released, the rotary control returns to the highest heat setting.

Fig.1 zeigt in Schrägansicht einen Drehregler 11 für ein Kochgerät K. Der Drehregler 11 weist ein Schaltgehäuse 12 auf, auf dem in grundsätzlich bekannter Weise ein drehbarer Drehknebel 13 aufgesetzt ist. Der Drehknebel 13 weist an seiner Oberseite 14 eine Markierung 15 zur Anzeige einer aktuellen Drehstellung auf. Mittels des Drehreglers 11 können insbesondere Betriebsparameter einer zugehörigen Kochzone des Kochgeräts eingestellt werden, wie hier mehrere Kochstufen von "1" bis "9" und eine Zonenzuschaltung. Fig.1 shows an oblique view of a rotary controller 11 for a cooking device K. The rotary controller 11 has a switch housing 12 on which a rotatable rotary knob 13 is placed in a generally known manner. The rotary knob 13 has a marking 15 on its upper side 14 to indicate a current rotational position. Operating parameters of an associated cooking zone of the cooking appliance can be set in particular by means of the rotary controller 11, such as several cooking levels from “1” to “9” and a zone activation.

Fig.2 zeigt in Draufsicht den Drehknebel 13 in einer neutralen Drehstellung oder Neutralstellung "0" (d.h., dass die Markierung 15 auf eine entsprechende Markierung an dem Kochgerät K zeigt, in welcher die zugehörige Kochzone deaktiviert ist bzw. nicht heizt). Zum Betreiben der Kochstelle kann der Drehknebel 13 im Uhrzeigersinn verdreht werden, wie durch den Pfeil angedeutet und durchläuft damit die den jeweiligen Kochstufen zugehörigen Kochstufen-Schaltstellungen "1" bis "9" bis zu der gewünschten Kochstufe oder Kochstufen-Schaltstellung. Zwischen der höchsten Kochstufen-Schaltstellung "9" und der Neutralstellung "0" befindet sich eine durch einen Doppelkreis angedeutete Zonenzuschaltstellung Z. Fig.2 shows the top view of the rotary knob 13 in a neutral rotary position or neutral position "0" (ie that the marking 15 points to a corresponding marking on the cooking device K, in which the associated cooking zone is deactivated or does not heat). To operate the hotplate, the rotary knob 13 can be turned clockwise, as indicated by the arrow and thus runs through the cooking level switching positions "1" to "9" associated with the respective cooking levels up to the desired cooking level or cooking level switching position. Between the highest cooking position switch position "9" and the neutral position "0" is a zone switch position Z indicated by a double circle.

Um zwischen der Neutralstellung "0" und den Kochstufen-Schaltstellungen "1" bis "9" durchschalten zu können, muss zwischen jeweils zwei benachbarten Schaltstellungen "0" bis "9" ein merklicher, aber vergleichsweise geringer Drehwiderstand überwunden werden oder analog ein merkliches, aber vergleichsweise geringes Drehmoment von rein beispielhaft nicht mehr als ca. 50 Ncm überwunden werden.In order to be able to switch between the neutral position "0" and the cooking level switching positions "1" to "9", a noticeable but comparatively low rotational resistance must be overcome between two adjacent switching positions "0" to "9" or, similarly, a noticeable, but comparatively low torque of, for example, no more than about 50 Ncm can be overcome.

Fig.3 zeigt den Drehknebel 13 in der höchsten Kochstufen-Schaltstellung "9", wobei hier und in den folgenden Figuren 4 und 5 die zu den Kochstufen-Schaltstellungen "1" bis "8" zugehörigen Markierungen des Kochgeräts K nicht eingezeichnet sind. Figure 3 shows the rotary knob 13 in the highest cooking level switch position "9", here and in the following Figures 4 and 5 the markings of the cooking device K associated with the cooking level switching positions "1" to "8" are not shown.

Fig.4 zeigt den Drehknebel 13 des Drehreglers 11 in der Zonenzuschaltstellung Z, aus welcher der Drehknebel 13 durch ein Weiterdrehen aus der höchsten Kochstufen-Schaltstellung "9" gelangt ist. Die Zonenzuschaltstellung Z ist als eine instabile, rückspringende Schaltstellung ausgebildet, welche dann, wenn das zum Drehen des Drehknebels 13 in die Zonenzuschaltstellung Z aufgewandte Drehmoment geringer als 200 Ncm ist (und insbesondere geringer als ca. 150 Ncm, insbesondere als ca. 100 Ncm ist), mit Nachlassen oder Loslassen des Drehknebels 13 eigenständig in die höchste Kochstufen-Schaltstellung "9" zurückkehrt, wie durch den Pfeil angedeutet. Durch Bringen des Drehknebels 13 auf die Zonenzuschaltstellung Z kann der dem Drehregler 11 zugehörigen Kochzone eine weitere Kochzone (z.B. eine Warmhaltezone) abwechselnd zugeschaltet und abgeschaltet werden. Figure 4 shows the rotary knob 13 of the rotary controller 11 in the zone switch-on position Z, from which the rotary knob 13 has come from the highest cooking level switch position "9" by turning further. The zone switch-on position Z is designed as an unstable, recessed switch position, which is when the torque used to turn the rotary knob 13 into the zone switch-on position Z is less than 200 Ncm (and in particular less than approximately 150 Ncm, in particular less than approximately 100 Ncm) ), with the release or release of the rotary knob 13 independently returns to the highest cooking setting "9", as indicated by the arrow. By moving the rotary knob 13 to the zone switch-on position Z, the cooking zone belonging to the rotary controller 11 can be switched on and off alternately with a further cooking zone (for example a warming zone).

Fig.5 zeigt den Drehknebel 13 in der Zonenzuschaltstellung Z mit Überführung in die Neutralstellung "0", wie durch den Pfeil abgedeutet. Hierzu muss ein höchstes Drehmoment aufgewandt werden, dass aber dennoch vorzugsweise geringer als 200 Ncm und insbesondere geringer als ca. 150 Ncm ist. Figure 5 shows the rotary knob 13 in the zone switch-on position Z with transfer to the neutral position "0", as indicated by the arrow. For this purpose, a maximum torque must be applied, but is nevertheless preferably less than 200 Ncm and in particular less than approximately 150 Ncm.

Selbstverständlich ist die vorliegende Erfindung nicht auf das gezeigte Ausführungsbeispiel beschränkt.Of course, the present invention is not limited to the exemplary embodiment shown.
