Abstract

A cut-out protection device in order to prevent overheating, especially in the case of an electric cooker having individual hotplates or a glass-ceramic cooking surface, characterised by the electric cooker being completely disconnected in the event of overheating.

Description

Die Erfindung betrifft einen Elektro-Kochherd mit einzelnen Herdplatten oder einer Glaskeramikkochfläche, insbesondere eine Abschaltsicherung zur Verhinderung einer Überhitzung der Kochplatten.The invention relates to an electric cooker with individual Stovetops or a ceramic hob, in particular a cut-out protection to prevent overheating the hot plates.

Elektro-Kochherde sind seit vielen Jahren bekannt. Sie ver­ fügen je nach Haushaltsbedarf über eine oder mehrere Koch­ stellen, an deren Unterseite Heiz- und Regelelemente ange­ ordnet sind.Electric cookers have been known for many years. You ver add one or more cook depending on household needs put on the underside of heating and control elements are arranged.

Die Kochplatten kann man einzeln durch einen an der Herd­ front angebrachten Schalter, je nach Gebrauch, ein-, aus-, vor- und zurückschalten.The hot plates can be individually by one on the stove front-mounted switch, depending on use, on, off, switch back and forth.

Dennoch wurden einige Fälle bekannt, in denen durch mensch­ liches Versagen wie z.B.Nevertheless, some cases have been reported in which humans failure such as

  • 1. spielende Kinder, die den Herd einschalten;1. children playing who turn on the stove;
  • 2. jemand vergißt, die Herdplatten rechtzeitig ab­ zustellen;2. someone forgets to remove the stove in time deliver;
  • 3. man schaltet ohne es zu bemerken die falsche Kochstelle ein;3. you switch the wrong one without realizing it Hotplate on;

großer Schaden durch einen daraus entstandenen Brand ange­ richtet wurde. great damage caused by a resulting fire was judged.  

Besonders hohe Brandgefahr besteht, wenn man den E-Herd über einen längeren Zeitraum hinweg (z.B. Urlaub) unge­ nutzt eingeschaltet läßt.There is a particularly high risk of fire if you use the electric stove over a longer period of time (e.g. vacation) uses turned on lets.

Ziel der Erfindung ist es, diese Gefahren gänzlich auszu­ schalten.The aim of the invention is to eliminate these dangers entirely switch.

Die Abschaltsicherung soll verhindern, daß die Kochplatten des Elektro-Kochherdes zu heiß werden oder durchbrennen.The cut-off protection is intended to prevent the hot plates of the electric cooker become too hot or burn.

Beschreibung des Schaltplans:Description of the circuit diagram:

In dem Elektro-Kochherd werden unter den Kochplatten Temperaturfühler oder -wächter installiert. Diese Fühler reagieren auf Überhitzung. Sie schalten bei einer be­ stimmten Temperatur, wenn eine Platte außergewöhnlich heiß wird, das Relais (d 2).Temperature sensors or monitors are installed under the hot plates in the electric cooker. These sensors react to overheating. They switch the relay ( d 2 ) at a certain temperature when a plate becomes exceptionally hot.

Das Relais (d 2) wird in einem Freiraum des Herdes ange­ bracht. Sobald das Relais (d 2) in Kraft tritt, ertönt eine Hupe, Summer oder Wecker (h 1) zur Warnung.The relay ( d 2 ) is placed in a free space in the cooker. As soon as the relay ( d 2 ) comes into effect, a horn, buzzer or alarm clock ( h 1 ) sounds as a warning.

Ferner kann zusätzlich ein Lichtsignal (h 2) eingebaut werden. (z.B. für Gehörlose)A light signal ( h 2 ) can also be installed. (e.g. for the deaf)

Summer, Wecker, Hupe und Lichtsignal sollten in der Schalterleiste des E-Herdes montiert werden.Buzzer, alarm clock, horn and light signal should be in the Switch strip of the electric cooker can be mounted.

Gleichzeitig mit dem Relais (d 2) wird das Zeitrelais (d 1) aktiviert, welches sich neben Relais (d 2) befindet. Das Zeitrelais (d 1) schaltet nach einer bestimmten Zeit­ spanne (ca. 15 sec), in der man durch Summer, Hupe, Wecker, oder Lichtsignal alarmiert, die Herdplatten aus- oder zu­ rückschalten kann, das Schütz (c 1) neben (d 1) und (d 2). Simultaneously with the relay ( d 2 ), the timing relay ( d 1 ), which is located next to relay ( d 2 ), is activated. The time relay ( d 1 ) switches after a certain period of time (approx. 15 sec), in which the buzzer, horn, alarm clock or light signal alarms, the stoves can be switched on or off, the contactor ( c 1 ) next to ( d 1 ) and ( d 2 ).

Das Schütz (c 1) unterbricht den Stromkreis und schaltet den Elektro-Kochherd komplett ab.The contactor ( c 1 ) breaks the circuit and switches the electric cooker off completely.

Das Schütz (c 1) hält sich selbst und kann nur mittels des Tasters (b 1) reaktiviert werden.The contactor ( c 1 ) holds itself and can only be reactivated using the button ( b 1 ).

Der Taster (b 1) wird ebenfalls in der Schalterleiste untergebracht.The button ( b 1 ) is also housed in the switch strip.
