Description
Anzeigevorrichtung für die Stellung des Stellgriffes elektrischer Geräte, insbesondere für Elektroherde Die Erfindung betrifft eine Anzeigevorrichtung für die Stellung des Stellgriffes elektrischer Geräte, insbesondere für Elektroherde oder dergleichen, die auch aus einer gewissen Entfernung vom Herd und bei schlechten Lichtverhältnissen leicht die Einstellung des Herdes erkennen lassen soll.
Erfindungsgemäss führen von den einzelnen Bereichen wenigstens einer Anzeigeskala optische Leiter zu einer von dem Stell griff der Anzeigevorrichtung bewegten Blende, die die Lichteintrittsstirnen nach Massgabe der Griffstellung gegen eine Lichtquelle abschirmt bzw. für die Licht quelle freigibt. Ein besonderer Vorteil einer solchen Anzeigevorrichtung besteht darin, dass die Lichtaus trittsstellen der optischen Leiter in einer anders ver laufenden Reihe als die Lichteintrittsstellen angeord net werden können. So können z. B. die Austrittsstellen in einer Geraden, die Eintrittsstellen in einem Kreis bogen aneinandergereiht sein.
Man kann dann für die Einstellung einen einfachen Drehgriff benutzen, der nur eine Bohrung für die Durchführung durch die Herd wand benötigt und kann dabei eine Anzeige in Form geradliniger Balken oder dergleichen erzielen, wie sie sich sonst nur bei Schiebergriffen ergibt, für deren Durchführung aber Schlitze und die entsprechenden Abdeckmettel erforderlich sind. Ein Getriebe, das die Drehbewegung des Handgriffes in eine Längsverschie bung der Anzeigebalken oder dergleichen umformt, ist nicht nötig, da es durch entsprechende Anordnung, Krümmung usw. der optischen Leiter in seiner Wir kung ersetzt wird.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.
Fig. 1 zeigt einen Ausschnitt aus einem Schaltpult eines Elektroherdes; Fig. 2 zeigt einen Schnitt nach der Ebene A-B der Fig. 1.
Auf den Schaltpult S ist ein Drehgriff 1 mit einer Welle 2 gelagert, die zur Steheinrichtung des Herdes führt. Auf der Welle sitzen drei Blendenscheiben 2', die Lichteintrittsstirnen 3 von optischen Leitern 4, beispielsweise Stäben aus durchsichtigem Kunststoff, gegen eine Lichtquelle 5 mit Reflektor 6 abschirmen können. Die Lichtaustrittsstirnen 7 dieser Leiter sind in Schlitzen 8 der Schaltpultwand aneinandergereiht, und zwar sind drei parallele Reihen angeordnet. Die Eintrittsstirnen 3 liegen dagegen auf einem Kreisbogen verteilt.
Die Blenden der Scheiben 2' sind derart gegeneinander versetzt, dass bei der Drehung des Griffes 1 von der Aus -Stellung zuerst die Licht- austrittsstirnen in dem obersten Schlitz 8 nachein ander aufleuchten, dann die der folgenden Schlitze. Die drei Schlitze sind den Bereichen Wärmen , Kochen und Braten zugeordnet.
Display device for the position of the handle of electrical devices, especially for electric stoves The invention relates to a display device for the position of the handle of electrical devices, especially for electric stoves or the like, which can easily recognize the setting of the stove even from a certain distance from the stove and in poor lighting conditions should.
According to the invention lead from the individual areas of at least one display scale optical conductors to a moved by the control handle of the display device screen, which shields the light entry foreheads according to the grip position against a light source or releases it for the light source. A particular advantage of such a display device is that the light exit points of the optical conductors can be arranged in a different row than the light entry points. So z. B. the exit points in a straight line, the entry points in a circle arc strung together.
You can then use a simple twist grip for setting, which only needs a hole for the implementation through the stove wall and can achieve a display in the form of straight bars or the like, as it otherwise only occurs with slide handles, but slots for implementation and the corresponding cover sheets are required. A gear that transforms the rotary movement of the handle in a longitudinal displacement environment of the indicator bar or the like is not necessary, since it is replaced by appropriate arrangement, curvature, etc. of the optical conductor in its action.
An embodiment of the invention is shown in the drawing.
1 shows a section from a control panel of an electric cooker; FIG. 2 shows a section along the plane A-B of FIG. 1.
On the control panel S, a rotary handle 1 is mounted with a shaft 2, which leads to the standing device of the stove. Sitting on the shaft are three diaphragm disks 2 ′, which can shield the light entry ends 3 of optical conductors 4, for example rods made of transparent plastic, from a light source 5 with reflector 6. The light exit ends 7 of these conductors are lined up in slots 8 of the control panel wall, namely three parallel rows are arranged. The entry foreheads 3, however, are distributed on an arc.
The diaphragms of the panes 2 'are offset from one another in such a way that when the handle 1 is turned from the off position, first the light exit foreheads in the topmost slot 8 light up one after the other, then those of the following slots. The three slots are assigned to the areas of heating, cooking and frying.
