Description

Glaskeramik- Herdplatte mit StromkontaktschutzGlass ceramic hob with electrical contact protection

Die Neuerung betrifft eine Herdplatte aus glasig-kristallinem Material, die eine Schutzvorrichtung aufweist, welche ▼erhindert, daß bei einer Beschädigung der Herdplatte der Benutzer durch die dann möglicherweise freiliegenden Stromleiter und Heizelemente gefährdet wird. The innovation relates to a stove plate of vitreous-crystalline material which has a protection device which ▼ erhindert that in a damage to the hearth plate, the user is endangered by the then possibly exposed electrical conductors and heating elements.

In jüngster Zeit beginnen sich Herdplatten immer »ehr durchzusetzen, bei denen sich die Stromleiter und Heiselemente unmittelbar unter einer Platte aus einem glasigkristallinen Material (Glaskeramik) befinden. In recent times, hotplates are beginning to prevail, in which the current conductors and hot elements are located directly under a plate made of a glass-crystalline material (glass ceramic).

Bricht eine solche Glaskeramik- Herdplatte aus irgendeinem Grunde, so ist der Benutzer des Herdes durch die letsspannuog führenden, freiliegenden elektrischen Heiselement« gefährdet*Will break such a ceramic hob out of any Basically, so is the user of the stove through the letsspannuog leading, exposed electrical hot element «endangered *

Aufgabe der vorliegenden Neuerung ist es, die Glaskeramik- Herdplatte mit einer Schutzvorrichtung auszustatten, die die Stromzufuhr su den Heizelementen sofort unterbricht, wenn die Glaskeramikplatte zerstört wird. The object of the present innovation is to equip the glass ceramic hob with a protective device that immediately interrupts the power supply to the heating elements if the glass ceramic plate is destroyed.

Der Berührungssohuts wird dadurch erreicht, daß auf der Unterseite der Glaskeramikplatte metallische Schutzleiter in geeigneter Weise aufgebracht sind, die in einen Hilfs stromkreis geschaltet sind, der bei Unterbrechung der The touch hat is achieved in that metallic protective conductors are applied in a suitable manner on the underside of the glass ceramic plate, which are connected in an auxiliary circuit that, when the

Schutzleiter durch Zerstörung der Glaskeramikplatte den HauptStromkreis des Herdes abschaltet. Eine mögliche Schutzschaltung dieser Art zeigt Figur 1.Protective conductor switches off the main circuit of the cooker by destroying the glass ceramic plate. A possible Protection circuit of this type is shown in FIG. 1.

Hauptstromkreis und Hilfsstromkreis sind durch einen Transformator 2 und ein Relais 4 galvanisch voneinander getrennt. Der Hilfsstromkreis wird mit einer ungefährlichen Niederspannung betrieben. Bei einer unterbrechung des Schutzleiter» 3 schaltet das Relais 4 den Hauptstrosikreis 5 ab.The main circuit and auxiliary circuit are galvanically separated from one another by a transformer 2 and a relay 4. The auxiliary circuit is operated with a harmless low voltage. If the protective conductor »3 is interrupted, the relay 4 switches off the main circuit 5 .

In figur 2 und Figur 3 sind zwei mögliche Varianten eines Schutzleiters 1, der als Leitsilberbahn auf der Plattenunterseite eingebrannt ist, abgebildet.FIG. 2 and FIG. 3 show two possible variants of a protective conductor 1, the conductive silver strip on the underside of the plate is branded, pictured.

Vorzugsweise wird der Schutzleiter so auf der Glaskeramikplatte angebracht, daß er, wie in Figur 2 dargestellt, den ganzen Plattenrand umfaßt. Mit einer solchen Schutzleiteranordnung wird der Hauptstromkreis in all den lallen abgeschaltet, in denen die Platte vom Rande her einreist oder durch mechanische Überbeanspruchung in mehrere Bruchstücke zerlegt wird. Risse, die im inneren Bereich der Platte auftreten, werden besser mit einer Schutzleiteranordnung gemäß Figur 3 erfaßt.Preferably, the protective conductor is attached to the glass ceramic plate that, as shown in Figure 2, the covers the entire platemark. With such a protective conductor arrangement, the main circuit is switched off in all the lalls, in which the plate enters from the edge or breaks into several fragments due to mechanical overstress is dismantled. Cracks that appear in the inner area of the plate are better with a protective conductor arrangement detected according to Figure 3.
