Problems solved by technology

However, when used as a cover for an induction hob, the heat of the cooking utensils placed on the cover and heated by the induction is transferred to the electronics arranged under the glass-ceramic plate, which is generally undesirable and disadvantageous of
The known use of glass-ceramic plates in radiant cooktops to cover induction cooktops is therefore not as good as it might appear at first glance

Embodiment Construction

[0031] figure 1 A hob with a cover 26 made of sheet metal is shown schematically. This cover plate 26 has a coated upper side for placing cooking utensils and a back side (not shown), said upper side being smooth and easy to clean, near the back side an induction heating element 28 is arranged for heating the Cooking utensils on the cover plate 26. The cover plate 26 according to the invention is used in induction hobs with a typical basin level and in induction hobs of the matrix module or micromodule type with a large number of smaller inductors arranged in a grid. Furthermore, use in hobs with radiant heating is conceivable.

[0032] figure 2 shown in cross section figure 1 The plate material of the middle cover plate 26, which shows the layer structure of the plate material. The sheet includes a substrate 10 and a plurality of layers 12 , 14 , 16 . exist figure 2 The orientation shown in corresponds to the orientation of the cover plate 26 in the operating state. ...

Abstract

The invention relates to a plate material, in particular a stove cover plate, made of a base material (10) and at least one coating (12, 14, 16). In order to provide a generic type of lightweight, stabile and temperature-resistant plate material, it is proposed that the base material (10) be designed as a pressed material comprising a ceramic matrix (18) and stiffening fibers (20).

Description

technical field [0001] The invention relates to a panel, in particular a panel for a cooktop cover, which comprises a base material and at least one layer. The invention also relates to a method for producing such a panel. Background technique [0002] EP 0819366 B1 discloses a sheet metal for producing a cover for an induction hob, which consists of a base material and a layer. The substrate is made of a ceramic which is not specified, and different possible materials for the layers are suggested. In the examples of EP 0819366 B1 it is proposed to produce a layer of glass fiber reinforced material. [0003] Covers for hobs are usually made of glass-ceramic material, which is very expensive to manufacture. Especially in applications for household appliances, the panels must withstand temperatures up to at least 700° C. and possess cleaning properties through a solid and smooth surface. The higher thermal conductivity of such a glass ceramic plate can be advantageous when...
