Definitions

  • the invention relates to a hob according to the preamble of claim 1.
  • a cooking surface with a ceramic plate is known (EP-A-03 13 137), in which the upper shelf is smooth and the underside of the plate outside the cooking area has a roughened structure, as a result of which the passage of light in the cooking area is different from that outside this cooking area.
  • a similar effect is achieved with a hotplate according to DE 35 03 576 A1, where outside the cooking area the underside of the plate is additionally provided with an opaque coating.
  • the object of the invention is to simplify the markings even further and to make them indestructible.
  • markings are produced in a simple manner by incorporating slight depressions into the surface of the plate, e.g. by laser technology in such a way that the surface of the depressions has a greater roughness (matting) than the rest of the plate surface.
  • the different surface structure of whatever type ensures that the markings are clearly recognizable on account of the different optical reflection behavior or the different optical refraction quotient compared to the other plate material.
  • Such optically recognizable material structures can be provided not only on the plate surface forming the standing surface of the hob, but also at any other point on the plate surface.
  • the hob shown in the figures has a plate 1 made of glass-ceramic material, which is bordered by a frame 2. Such a hob can be used in a corresponding cutout of a kitchen worktop. Below the plate 1 there are several electric radiators, not shown, e.g. Radiant heater, arranged. To mark or mark the corresponding cooking surfaces immediately above these radiators, the plate 1 has markings 3 in the form of circular or oval lines, which mark circular or concentric cooking surfaces 4, 5, 6, 7 and an oval cooking surface 8 in their contours. As shown in particular in the sectional view according to FIG. 2, these markings 3 and 3 'are formed by linear material or surface structures which differ from the material or surface structure of the adjacent plate material. In Fig.
  • recesses 9 are provided in the plate surface with a surface structure which has a greater roughness than the surface structure of the plate 1. It is sufficient if these recesses 3 have a depth of a few hundredths of a millimeter; if necessary, a light, line-shaped or point-shaped roughening of the plate surface is sufficient, as illustrated at point 3 'in FIG. 1.
  • Such a different material or surface structure can be produced in a simple manner by means of laser technology.

Claims (2)

  1. Table de cuisson comportant un plan de pose pour la vaisselle qui est constitué par une plaque de verte ou de matériau vitro-céramique et qui, pour le repérage des zones de cuisson chauffées, présente des marques constituées par des discontinuités en forme de lignes dans la surface lisse par ailleurs, lesquelles discontinuités sont obtenues par enlèvement de matière, caractérisée par le fait que les discontinuités (3) en forme de lignes sont exclusivement constituées par des creux (9) qui sont aménagés dans la surface de la plaque et dont les surfaces présente une rugosité.
  2. Table de cuisson selon la revendication 1, caractérisée par le fait que les marques (3) sont constituées par des creux (9) qui sont aménagés dans la surface de la plaque et dont la structure superficielle diffère de celle des surfaces voisines, par exemple est rendue mat.
