Description

Elektrische Kochplatte mit Einrichtung zum magnetischen Festhalten des Kochgefäßes Der Erfindungsgegenstand gehört zur Klasse der elektrischen Kochplatten, die mit einer Einrichtung zum magnetischen Festhalten des Kochgefäßes bei eingeschaltetem Heizstrom oder unabhängig von ihm mit Hilfe des magnetisierbaren Kochplattenkörpers ausgerüstet sind.Electric hotplate with magnetic retention device of the cooking vessel The subject of the invention belongs to the class of electric hotplates, the one with a device for magnetically holding the cooking vessel when it is switched on Heating current or independently of it with the help of the magnetizable hotplate body are equipped.

Das Wesen der Erfindung besteht darin, daß eine Erregerspule am Umfange einer mit besonderer Heizwicklung versehenen fugenlosen Kochplatte mit geschlossener Heizfläche angeordnet ist. Die Fugenlosigkeit des magnetisierbaren Kochplattenkörpers ist von besonders praktischer Bedeutung gegenüber den bekannten Ausführungen von magnetisierbaren Kochplattenkörpern; bei denen die Magnete in diese selbst eingebaut sind mit der Folge, daß Trennungsfugen vorgesehen sein müssen. Durch die Fugenlosigkeit des Kochplattenkörpers wird z. B. ein Eindringen von Flüssigkeit des Kochgutes in den Kochplattenkörper unmöglich gemacht.The essence of the invention is that an excitation coil on the circumference a jointless hotplate with a closed heating coil Heating surface is arranged. The seamlessness of the magnetizable hotplate body is of particular practical importance compared to the known versions of magnetizable hotplate bodies; where the magnets are built into them themselves are with the result that separation joints must be provided. Because of the seamlessness the hotplate body is z. B. penetration of liquid in the food made the hotplate body impossible.

In der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform veranschaulicht, und zwar zeigt Abb: i im Schnitt eine eiserne Kochplatte mit einer ihren Umfang umschließenden Erregerspule.In the drawing, the subject matter of the invention is shown in an exemplary embodiment illustrates, namely shows Fig: i in section an iron hotplate with a the excitation coil surrounding its circumference.

Abb. z zeigt im Schnitt eine magnetische Kochplatte, bei der die Heizwicklungen gleichzeitig als Erregerwicklungen konzentrisch und hitzebeständig isoliert in Nuten des KochplattenkÖrpers angeordnet :sind.Fig. Z shows a section of a magnetic hotplate with the heating coils at the same time as excitation windings, concentrically and heat-resistant insulated in grooves of the hotplate body: are.

Gemäß Abb. i ist die eiserne Kochplatte als Kern der sie umschließenden Erregerwicklung 8 ausgebildet. Die Erregerwicklung 8 ist von dem die fugenlose Kochplatte bildenden Kern i durch Luftkanal cj gegen Wärmeleitung isoliert.According to Fig. I, the iron hotplate is the core of the surrounding area Excitation winding 8 is formed. The excitation winding 8 is one of the seamless hotplate forming core i insulated against heat conduction by air duct cj.

Bei der Ausführung nach Abb. z ist die fugenlose Kochplatte i mit Heizfläche a auf der Unterseite mit Nuten versehen, in welchen Wicklungen 8 hochhitzebeständig isoliert angeordnet sind. Diese Wicklungen bilden gleichzeitig Heiz- und Erregerwicklungen. Die Magnetpole entstehen dabei in ,der fugenlosen- Heizfläche a.In the design according to Fig. Z, the jointless hotplate i is with Provided heating surface a on the underside with grooves in which windings 8 are highly heat-resistant are arranged isolated. These windings form heating and excitation windings at the same time. The magnetic poles are created in the seamless heating surface a.

Die Erregerwicklungen können entweder in Reihe oder parallel mit der Heizwicklung oder auch unabhängig von dieser ein- und äusschaltbar sein.The excitation windings can either be in series or in parallel with the Heating winding can be switched on and off independently of this.
