- Toggle for actuating a household appliance in particular a cooking appliance, which has a cylindrical base body and is rotatable about the central axis of the cylindrical base body.
- the invention relates to a household appliance, in particular a cooking appliance, for example a gas hob or a gas oven, with such a gag.
- the household appliance has one or more toggles, with which various functions of the household appliance are controlled by the operator.
- the heating power is usually adjusted by means of the knob, usually by turning the knob.
- the knob is attached to a control shaft, which transmits a rotational movement of the knob in the interior of the household appliance, such as a gas valve or an electric signal generator.
- the control shaft is coaxial with the central axis of the toggle, which is also the central axis of the cylindrical body of the toggle.
- each hob and possibly the oven is assigned a separate toggle.
- the toggle In addition to the rotation of the knob about its central axis of the toggle can be additionally axially displaceable in the direction of its central axis.
- the axial displaceability of the knob can be used to allow a sinking of the knob in an inoperative position in the household appliance.
- In the inoperative position is an end-side top surface of the knob at least approximately in the plane of a control panel of the household appliance.
- the present invention is therefore based on the object to provide a toggle available that is safe to operate both in the direction of rotation and in the axial direction.

Abstract
Description
Knebel zur Betätigung eines Haushaltsgeräts, insbesondere eines Gargeräts, der einen zylindrischen Grundkörper aufweist und um die Mittelachse des zylindrischen Grundkörpers drehbar ist. Ebenfalls betrifft die Erfindung ein Haushaltsgerät, insbesondere ein Gargerät, beispielsweise eine Gaskochmulde oder ein Gasbackofen, mit einem solchen Knebel.Toggle for actuating a household appliance, in particular a cooking appliance, which has a cylindrical base body and is rotatable about the central axis of the cylindrical base body. Likewise, the invention relates to a household appliance, in particular a cooking appliance, for example a gas hob or a gas oven, with such a gag.
Das Haushaltsgerät weist einen oder mehrere Knebel auf, mit denen verschiedene Funktionen des Haushaltsgeräts von der Bedienperson gesteuert werden. Bei Gargeräten wird mittels des Knebels in der Regel die Heizleistung eingestellt, in der Regel durch Drehen des Knebels. Der Knebel ist hierzu auf eine Steuerwelle aufgesteckt, die eine Drehbewegung des Knebels in das Innere des Haushaltsgeräts, beispielsweise auf ein Gasventil oder auf einen elektrischen Signalgeber überträgt. Die Steuerwelle ist koaxial zu der Mittelachse des Knebels, welche gleichzeitig die Mittelachse des zylindrischen Grundkörpers des Knebels ist. Bei Gargeräten ist üblicherweise jeder Kochstelle sowie gegebenenfalls dem Backofen jeweils ein eigener Knebel zugeordnet.The household appliance has one or more toggles, with which various functions of the household appliance are controlled by the operator. In cooking appliances, the heating power is usually adjusted by means of the knob, usually by turning the knob. The knob is attached to a control shaft, which transmits a rotational movement of the knob in the interior of the household appliance, such as a gas valve or an electric signal generator. The control shaft is coaxial with the central axis of the toggle, which is also the central axis of the cylindrical body of the toggle. In cooking appliances usually each hob and possibly the oven is assigned a separate toggle.
Neben der Drehbarkeit des Knebels um seine Mittelachse kann der Knebel zusätzlich in Richtung seiner Mittelachse axial verschiebbar sein. Die axiale Verschiebbarkeit des Knebels kann eingesetzt werden, um ein Versenken des Knebels in eine Außerbetriebsstellung im Haushaltsgerät zu ermöglichen. In der Außerbetriebsstellung befindet sich eine stirnseitige Deckfläche des Knebels zumindest annähernd in der Ebene einer Bedienblende des Haushaltsgeräts. Durch kurzzeitiges Drücken des Knebels wird der Knebel mittels Federkraft von der Außerbetriebsstellung in eine Betätigungsstellung ausgefahren. Der in Betätigungsstellung befindliche Knebel kann um seine Mittelachse gedreht und damit das Haushaltsgerät gesteuert werden.In addition to the rotation of the knob about its central axis of the toggle can be additionally axially displaceable in the direction of its central axis. The axial displaceability of the knob can be used to allow a sinking of the knob in an inoperative position in the household appliance. In the inoperative position is an end-side top surface of the knob at least approximately in the plane of a control panel of the household appliance. By briefly pressing the toggle the knob is extended by spring force from the inoperative position to an actuating position. The knob located in the operating position can be rotated about its central axis and thus the household appliance can be controlled.
Ebenfalls bekannt ist es, durch axiales Verschieben des Knebels eine Funktion des Haushaltsgeräts zu steuern. Beispielsweise bei Gaskochstellen kann durch Drücken des Knebels ein Gasbrenner gezündet werden.It is also known to control a function of the household appliance by axially displacing the knob. For example, in gas hobs can be ignited by pressing the toggle a gas burner.
Bekannte Knebel mit einem zylindrischen Grundkörper erweisen sich dann als ergonomisch nachteilig, wenn ein relativ großes Betätigungsmoment erforderlich ist, um den Knebel zu drehen. In diesem Fall besteht die Gefahr eines Abrutschens der Finger der Bedienperson an der zylindrischen Mantelfläche des Knebels. Die Gefahr eines Abrutschens besteht gleichermaßen, wenn eine Zugkraft auf den Knebel ausgeübt werden soll.Known gag with a cylindrical body prove to be ergonomically disadvantageous when a relatively large actuation torque is required to turn the knob. In this case, there is a risk of slipping of the fingers of the operator on the cylindrical surface of the knob. The risk of slipping is equally when a tensile force is to be applied to the knob.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Knebel zur Verfügung zu stellen, der sowohl in Drehrichtung als auch in axialer Richtung sicher betätigbar ist.The present invention is therefore based on the object to provide a toggle available that is safe to operate both in the direction of rotation and in the axial direction.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine Mantelfläche des zylindrischen Grundkörpers zwei Ausnehmungen besitzt, wobei jede Ausnehmung eine parallel zur Mittelachse ausgerichtete ebene Teilfläche aufweist und die ebenen Teilflächen der beiden Ausnehmungen zueinander im Wesentlichen parallel sind. Der Knebel besitzt die Grundform eines Zylinders, von dem in Betriebsstellung des Knebels die zylindrische Mantelfläche sowie eine stirnseitige Deckfläche sichtbar sind. In der Mantelfläche sind zwei Ausnehmungen angeordnet, in denen die Oberfläche des Knebels in Bezug auf die Mantelfläche nach innen versetzt ist. Die Ausnehmungen definieren jeweils eine ebene Teilfläche, die im Wesentlichen parallel zu der Mittelachse des Knebels ausgerichtet ist. Die ebenen Teilflächen der beiden Ausnehmungen sind zueinander parallel. Diese ebenen Teilflächen erleichtern es für eine Bedienperson erheblich, ein Drehmoment auf den Knebel auszuüben. Hierzu greift die Bedienperson den Knebel an den ebenen Teilflächen mit zwei Fingern einer Hand.This object is achieved in that a lateral surface of the cylindrical base body has two recesses, each recess has a parallel to the central axis aligned planar face and the flat faces of the two recesses are substantially parallel to each other. The toggle has the basic shape of a cylinder, of which in the operating position of the toggle, the cylindrical outer surface and a front-side top surface are visible. In the lateral surface two recesses are arranged, in which the surface of the knob is offset in relation to the lateral surface inwards. The recesses each define a planar partial surface, which is aligned substantially parallel to the central axis of the knob. The flat partial surfaces of the two recesses are parallel to each other. These flat faces make it much easier for an operator to exert a torque on the gag. For this purpose, the operator grips the knob on the flat partial surfaces with two fingers of one hand.
Bevorzugt weist jede ebene Teilfläche eine Ausdehnung in Richtung senkrecht zur Mittelachse auf, die mindestens einem Drittel, vorzugsweise mindestens der Hälfte des Durchmessers des zylindrischen Grundkörpers entspricht. Die Ausdehnung der Teilflächen in Richtung senkrecht zur Mittelachse entspricht dem Hebelarm, mit dem zwei auf die Teilflächen wirkende Druckkräfte ein auf den Knebel wirkendes Drehmoment bewirken.Each flat partial surface preferably has an extension in the direction perpendicular to the central axis, which corresponds to at least one third, preferably at least half, of the diameter of the cylindrical basic body. The extension of the partial surfaces in the direction perpendicular to the central axis corresponds to the lever arm with which two pressure forces acting on the partial surfaces cause a torque acting on the toggle.
Die ebenen Teilflächen bilden damit Betätigungsflächen zum Drehen des Knebels.The flat partial surfaces thus form actuating surfaces for rotating the knob.
Weitere Vorteile werden erzielt, wenn der Knebel parallel zu der Mittelachse verschiebbar ist.Further advantages are achieved if the knob is displaceable parallel to the central axis.
Jede der Ausnehmungen besitzt einen unteren Übergangsbereich, in welchem die ebene Teilfläche der Ausnehmung in die Mantelfläche des zylindrischen Grundkörpers übergeht. Dieser Übergangsbereich kann beispielsweise als Schräge oder als konkave Wölbung ausgeführt sein.Each of the recesses has a lower transition region, in which the planar partial surface of the recess merges into the lateral surface of the cylindrical base body. This transition region can be designed for example as a slope or as a concave curvature.
Mit besonderem Vorteil bilden die unteren Übergangsbereiche der Ausnehmung eine Betätigungsfläche zum Drücken des Knebels. Die Übergangsbereiche sind dazu geeignet, eine axiale Kraft auf den Knebel auszuüben. Die Anordnung der unteren Übergangsbereiche, angrenzend an die ebenen Teilflächen, ermöglicht es, den Knebel gleichzeitig zu drücken und zu drehen. Eine solche kombinierte Bewegung ist üblicherweise zum Zünden einer Gaskochstelle erforderlich.With particular advantage, the lower transition regions of the recess form an actuating surface for pressing the knob. The transition areas are adapted to exert an axial force on the gag. The arrangement of the lower transition areas, adjacent to the flat faces, makes it possible to simultaneously press and turn the knob. Such a combined movement is usually required to ignite a gas hob.
Weiter weist jede der Ausnehmungen einen oberen Übergangsbereich auf, in welchem die ebene Teilfläche der Ausnehmung in die Mantelfläche des zylindrischen Grundkörpers übergeht. Die oberen Übergangsbereiche sind symmetrisch zu den unteren Übergangsbereichen angeordnet. Sie ermöglichen es, eine Zugkraft auf den Knebel auszuüben. Gleichzeitig kann der Knebel durch Kraftausübung auf die ebenen Teilflächen gedreht werden. Die oberen Übergangsbereiche haben ebenfalls eine Schräge oder eine konkave Wölbung.Furthermore, each of the recesses has an upper transition region, in which the planar partial surface of the recess merges into the lateral surface of the cylindrical basic body. The upper transition areas are arranged symmetrically to the lower transition areas. They make it possible to exert a pulling force on the gag. At the same time, the toggle can be turned by applying force to the flat partial surfaces. The upper transition areas also have a slope or a concave curvature.
Der zylindrische Grundkörper weist eine stirnseitige, vorzugsweise ebene oder leicht gewölbte Deckfläche auf, die senkrecht zur Mittelachse ausgerichtet ist. Die Deckfläche bildet den für die Bedienperson sichtbaren Abschluss auf der Stirnseite des Knebels. Die Deckfläche ist auch dann sichtbar, wenn der Knebel in eine Bedienblende des Haushaltsgeräts versenkt ist.The cylindrical base body has an end face, preferably flat or slightly curved top surface, which is aligned perpendicular to the central axis. The top surface forms the visible for the operator conclusion on the front side of the knob. The top surface is also visible when the knob is sunk in a control panel of the household appliance.
Vorzugsweise besitzt die Deckfläche die Form einer Kreisscheibe. Der Knebel kann damit in beliebiger Rotationsposition in einer Kreisöffnung einer Blende eines Haushaltsgeräts versenkt werden. Der Spalt zwischen Öffnung und Knebel ist über seinen gesamten Umfang zumindest annähernd gleich.Preferably, the top surface has the shape of a circular disk. The toggle can thus be sunk in any rotational position in a circular opening of a panel of a household appliance. The gap between the opening and toggle is at least approximately the same over its entire circumference.
Weiter stellt die Deckfläche eine Betätigungsfläche zum Drücken des Knebels dar. Auf die Deckfläche wird insbesondere dann gedrückt, wenn der Knebel in der Bedienblende versenkt werden soll.Next, the top surface is an actuating surface for pressing the toggle. On the top surface is particularly pressed when the toggle is to be sunk in the control panel.
Der erfindungsgemäße Knebel ist mit besonderem Vorteil einsetzbar in einem Haushaltsgerät, insbesondere einem Gargerät, beispielsweise einer Gaskochmulde oder einem Gasbackofen. Insbesondere mit Gas beheizte Gargeräte erfordern ein gleichzeitiges Drücken und Drehen des Knebels. Die erfindungsgemäße Formgebung des Knebels ermöglicht dies in ergonomisch besonders günstiger Weise.The gag according to the invention can be used with particular advantage in a household appliance, in particular a cooking appliance, for example a gas hob or a gas oven. In particular, with gas heated cooking appliances require simultaneous pressing and turning the knob. The inventive design of the gag allows this ergonomically particularly favorable manner.
Mit besonderem Vorteil ist durch Ziehen des Knebels eine Zusatzfunktion, beispielsweise eine Kindersicherung oder eine Boostfunktion oder ein Timer betätigbar. Die erfindungsgemäße Formgebung ermöglicht es erstmals, einen Knebel in ergonomisch günstiger Weise zur Bedienperson hin zu ziehen. Damit können zusätzliche Funktionen mit demselben Knebel betätigt werden.With particular advantage by pulling the knob an additional function, such as a child safety or a boost function or a timer can be actuated. The shaping according to the invention makes it possible for the first time to pull a gag in an ergonomically favorable manner towards the operator. This allows additional functions to be operated with the same knob.
Die Deckfläche des als Versenkknebel ausgeführten Knebels ist in versenkter Position im Wesentlichen bündig mit einer Blende des Haushaltsgeräts.The top surface of the executed as a countersunk toggle is in retracted position substantially flush with a panel of the household appliance.
Weitere Vorteile und Ausgestaltungen der Erfindung werden anhand des in den schematischen Figuren dargestellten Ausführungsbeispiels näher erläutert.Further advantages and embodiments of the invention will be explained in more detail with reference to the embodiment shown in the schematic figures.
