Description
Die Erfindung betrifft eine Schaltvorrichtung an elektrischen Herden, insbesondere Großkochherden.The invention relates to a switching device on electric cookers, in particular Large cooking stoves.
Bekanntlich treten im Schaltraum elektrischer Herde, insbesondere elektrischer Großkochherde, sehr hohe Temperaturen auf, die das einwandfreie Arbeiten des oder der Regelschalter stark beeinträchtigen. Oft sind die Kontakte der Regelschalter so stark erhitzt, daß sie beim Abschalten unter Last auf eine andere Regelstufe verschmonen, wodurch der Regclschalter unbrauchbar wird.It is well known that electric stoves, especially large electric cooking stoves, occur in the control room very high temperatures that make the control switch (s) work properly severely affect. Often the contacts of the control switches are so hot that that when they are switched off under load to another control stage, so that the Regcl switch becomes unusable.
Durch die Erfindung werden diese Schwierigkeiten dadurch vermieden, daß der Regelschalter nicht wie bisher die volle Last abschaltet, sondern lediglich zum Einstellen der neuen Regelstellung dient. Die Unterbrechung des Kochstromes macht sich kaum bemerkbar, da sie nur so lange dauert, bis der kcgelschalter in die neue Regelstellung gelangt ist.The invention avoids these difficulties in that the control switch does not switch off the full load as before, but only to set the new control position is used. The interruption of the cooking current is hardly noticeable, as it only lasts until the bell switch has reached the new control position is.
Gegenstand der Erfindung ist daher, daß beim Einstellen einer neuen Regelstellung der Regelschalter zusammen mit dem Herd durch einen vom Regelschalter gesteuerten zusätzlichen Schalter selbsttätig vorübergehend vom Netz getrennt wird.The invention is therefore that when setting a new control position, the control switch together with the stove temporarily automatically by an additional switch controlled by the control switch is disconnected from the mains.
Der Erfindungsgedanke ist in der Zeichnung beispielsweise schematisch dargestellt.The idea of the invention is shown schematically in the drawing, for example.
Der Regelschalter δ steuert die Beheizung des Herdes d. Zwischen Regelschalter δ und I Iwdd einesteils und dem Netz g anderntfils liegt in bekannter Weise der Hauptschalter/. Die Achse des Regelschaltiers b ist in nicht dargestellter Weise mit Nocken verschen, die jeweils in bezug auf die einzelnen Regclstellungen voreilend angeordnet sind und bei Betätigung des Regelschalters b den am Rcgelschalter angebrachten Vorkontakt« schließen, bevor ein Weiterschalten des Regelschaltcrs in die neue Regelstellung erfolgt ist. Durch dieses Schließen des Vorkontaktes« erhält das Schaltschütze Spannung lind 'öffnet dadurch über den Ankerh den Hauptschalter/, so daß Regelschalterb und Herdi/ vom Netz getrennt werden. Hat der Regelschalter/; die nächste Regelstellung erreicht, so gibt der entsprechende nicht dargestellte Nocken den Vorkontaktß frei, so daß dieser sich öffnen kann und dadurch das Schütze abschaltet. Der Hauptschalter/ wird also freigegeben und kann in an sich bekannter Weise beispielsweise durch Federkraft oder sein eigenes Schwergewicht wieder einfallen tmd Regelschalter b und Herd d wieder an das Netz σ schalten.The control switch δ controls the heating of the stove d. The main switch / is located in a known manner between the control switch δ and I Iwdd on the one hand and the network g anderntfils. The axis of the control switch b is given away in a manner not shown with cams, which are arranged in advance with respect to the individual control positions and close the pre-contact attached to the control switch when the control switch b is actuated before the control switch is switched to the new control position . By this closing of the pre-contact "the contactor receives voltage and opens the main switch / via the armature h , so that control switch b and Herdi / are disconnected from the mains. Does the control switch /; When the next control position is reached, the corresponding cam, not shown, releases the pre-contact so that it can open and thereby switch off the contactor. The main switch / is thus released and can fall back in in a manner known per se, for example by spring force or its own heavy weight, and switch control switch b and stove d back to the network σ.
Regelschalter und Vorkontakt können auch so ausgebildet werden, daß bei Nullstellung des Regelschalters ein entsprechend angeordneter Nocken den Vorbontakt geschlossen hält, so daß das Schaltschütz e den Hauptschalter/ abschaltet. Durch Anordnen eines Schalters c an beliebiger Stelle des Herdes kann ein Öffnen des Hauptschalters/zu jeder beliebigen Zeit bewirkt werden. Weiterhin kann der Hauptschalter/ selbst mit einer entsprechenden Vorrichtung versehen sein, tim ihn von Hand in bekannter Weise betätigen zu können. Das Schaltschütz e kann außerdem in an sich bekannter Weise mit einem Überstrom- und Nullspannungsschutz ausgerüstet sein.Control switch and pre-contact can also be designed so that when the control switch is in the zero position, a correspondingly arranged cam keeps the pre-contact closed so that the contactor e switches off the main switch /. By arranging a switch c anywhere on the cooker, the main switch / can be opened at any time. Furthermore, the main switch itself can be provided with a corresponding device so that it can be operated by hand in a known manner. The contactor e can also be equipped in a manner known per se with overcurrent and zero voltage protection.
