Definitions

  • the present invention relates to a glass-ceramic plate intended in particular to cover or receive heating elements, in particular intended to serve as a hob, and its manufacturing process.
  • a glass ceramic is originally a glass, said precursor glass, whose specific chemical composition can cause by suitable heat treatments, called ceramization, a controlled crystallization. This specific partly crystallized structure gives the glass ceramic unique properties.
  • a glass-ceramic plate must generally have a transmission in the wavelengths of the visible range that is low enough to mask at least a part of the heating elements underlying the rest and sufficiently high that, for safety purposes, the user can visually detect the heating elements in working order; it must also have a high transmission in the wavelengths of the infrared range.
  • the current main plates are dark in color, especially black, but there are also lighter-looking plates (especially white or cream, for example having a blur of at least 50% as described in the patent FR2766816 ) or transparent plates with opacifying coatings.
  • enamels or paints can be found, these coatings being able to be found, as the case may be, on the upper face (in use position) and / or on the lower side of the plate, and these coatings may be decorative and / or functional character, for example may represent logos and / or define heating zones, and / or may be used to hide underlying elements (heating elements or underlying metal structures), etc.
  • these coatings also have drawbacks such as greater risks of thermal degradation in the vicinity of the heating elements, or certain annoying optical effects visible in the apparent face (where appropriate, image splitting, appearance variations and / or contrasts according to the proximity of the underlying elements and / or at the edges, iridescence phenomena according to which the color appears different according to the angle under which one looks at the plate or according to the angle of illumination of the plate , etc.).
  • the object of the present invention was therefore to propose a solution adapted to clear plates, in particular to find a simple and economical solution to enable, in particular from their unexposed face (or lower face or back face, etc.), an appropriate masking of elements covered by the plate without undesirable unsightly effects (reflections, color changes, etc.), the modifications made combining with said plates for a homogeneous effect without said modifications having any adverse effects on the properties usually sought.
  • This solution consists in proposing a new vitroceramic plate having a coating giving said plate a uniform appearance, in particular making it possible to obtain, when the plate is mounted and / or in use, a uniform coloring between the coated parts (used in particular to mask supporting or mounting members of the plate) and uncoated portions.
  • the plate being in particular light in color and the coating (on at least one zone) being in the non-apparent face, the color variation (which can result in delta values E * as defined later) opposite ( opposite)), visible to the user, remains limited, for example in the case of mounting on a range, the entire apparent surface of the plate including the plumb with the mounting frame or support means.
  • the new plate according to the invention is a glass-ceramic plate, intended for example to cover or receive at least one heating element, in particular intended to serve as a cooking plate, said plate being coated, in at least one zone of a face of a coating such that the total deviation of delta E *, measured on the opposite face, between said coated zone and an uncoated zone, is less than approximately 1 and / or such that it (the coating) has a luminance L * greater than about 70.
  • coating is meant in the present invention a coating type paint or resin (s) or even enamel type, this coating is generally deposited in liquid or semi-liquid form (for example in the form of of a paste), and generally undergoing drying, curing and / or subsequent firing.
  • glass ceramic plate is meant hereinafter not only the plates made of glass-ceramic proper but also the plates of any other similar material resistant to high temperature and having a coefficient of expansion of zero or almost zero (for example less than 15.10 -7 K -1 ). Preferably, however, it is a glass-ceramic plate proper.
  • the plate is more particularly based on a light-colored semi-transparent or translucent glass-ceramic (other than black or brown), in particular is a glass-ceramic plate of substantially white color (appearing white in the eye or cream or vanilla or pulling very lightly on yellow or other hues).
  • a light-colored semi-transparent or translucent glass-ceramic other than black or brown
  • a glass-ceramic plate of substantially white color applying white in the eye or cream or vanilla or pulling very lightly on yellow or other hues.
  • Such plates are for example marketed under the name Kerawhite or Kerabiscuit or KeraVanilla by the company Eurokéra.
  • the above-mentioned coating is advantageously located on at least one zone of the face of the plate intended to be hidden in the mounting and / or use position, this face being generally that facing towards the heating elements in the use position ( underside or inside or back).
  • This coating covers at least one zone of said face, for example all or part of the peripheral zone of this face, this zone being generally intended to cover at least one or several mounting or support elements, and may cover several zones or even one significant part (or all) of said face, except however generally at least the heating zones, the distance between said areas and the coating being preferably at least 2.5 cm.
  • the coating can be used to mask, at least in part, elements such as support or mounting parts or frames (these parts are generally also substantially white or painted white for the clear plates), but can also be used where appropriate to mask other elements such as displays or even heating elements (while allowing their detection in working order), etc.
  • the present invention has demonstrated that for a light-colored glass ceramic, the above-mentioned coating, which is also light in color, makes it possible to compensate and considerably attenuate the undesirable optical effects, the interaction between the colors of the coating and the neutralizing plate, in particular the effects of the different reflections of the light in certain zones masking elements, preventing unsightly contrasts or iridescence phenomena at the edge, etc.
  • the coating fulfills its role of masking at the chosen locations and does not affect the properties of the glass-ceramic plate.
  • the coating is fully compatible with existing production lines, in particular can be applied by screen printing using the usual fabrics and presses. It is economical and is also compatible with all types of heating.
  • the coating has a coloration that can be characterized using colorimetric coordinates designated by the letters a *, b * and L *, a * and b * characterizing the chromaticity (the axis a * corresponding to the green pair -red and the axis b * corresponding to the blue-yellow pair), and L * characterizing the luminance (or clarity) of the measured sample (L * ranging from 0 for the black to 100 for the absolute white), the coordinates in question deriving from the X, Y and Z trichromatic coordinates defined and proposed in 1931 by the International Commission on Illumination (CIE), unanimously recognized as a reference body in the field of colorimetry.
