Definitions

  • the invention relates to a cooking device with optical temperature display and method for optical temperature display on a cooking device.
  • thermochromic paint on and / or under a cooktop panel. This is above a heater in the form of a radiant heater. In operation of the radiant heater, the thermochromic ink is heated, and at a choice of 40 ° C to 80 ° C for a color change or as a turnover temperature after switching off the radiant heater, the color change as long as the temperature of the cooktop plate and thus the thermochromic color about it lies.
  • the cooktop panel itself is to be coated with the thermochromic paint.
  • thermochromic paint on the interior of a pot bottom.
  • a calibration to certain temperatures on the cooking vessel bottom can be made.
  • thermochromic material as an indicator.
  • the thermochromic material is provided on a lamp under the hob plate, for example as a kind of coating over the lamp or as a coating on the glass bulb or lamp body. This lamp is located at a distance from the bottom of the hob plate.
  • thermochromic material on top of the top of a hob plate.
  • a color change is optimally visible, just as a temperature indicator or as a warning.
  • the invention has for its object to provide a cooking device mentioned above and methods for displaying temperature on such a cooking device with which problems of the prior art can be achieved and in particular an advantageous way to display optical temperature or residual heat indicator on a cooking device, in particular on a Hob, can be created.
  • the cooking device comprises a hob plate with a heater underneath for heating a cooking vessel placed above it on the hob plate.
  • an optical display device for a temperature below the cooking plate and provided close to the heater.
  • a distance may be in the range of a few cm, for example 1 cm to 5 cm, it being also possible that the display device is directly adjacent to the heater or even disposed therebetween and the hob plate.
  • the display device has thermochromic ink or thermochromic material, which is provided for the hob plate or is visible through the hob plate.
  • thermochromic ink or the thermochromic material is not directly or not permanently attached to the hob plate and not directly or not insoluble applied as a coating on this, but on a separate carrier.
  • this carrier is applied or pressed with the thermochromic material against the underside of the hob plate, but the actual application of the thermochromic material takes place just on a separate carrier.
  • the thermochromic material may also be applied insoluble.
  • the thermochromic material which is advantageously in powder form, can be mixed in a paint or in a coating, which in turn can then be applied or applied by a suitable method.
  • the optical properties of the material or the coating after completion are largely determined by the admixed thermochromic material, so that in this regard, the color can be considered equated with the thermochromic material.
  • the thermochromic material may be such that it turns with a color change at a temperature increase over a Umtschtemperatur of colored towards transparent or at least very bright or translucent and not strong or opaque changes.
  • a warning of too high cooktop temperature If this high temperature is above the aforementioned turnover temperature, the thermochromic material becomes transparent and the warning becomes visible. If the temperature drops again after a cooking process, when the temperature drops below the reversal temperature, a reverse color change takes place and the warning is again hidden.
  • another color change can be used or achieved by a suitable choice of material, for example, from transparent or an inconspicuous, dark color to a conspicuous Color when exceeding a turnover temperature.
  • a warning is visible as long as the temperature is above the Umschlagtemperatur, and disappears again when falling below.
  • thermochromic material in a further embodiment of the invention, it is possible that a plurality of layers of thermochromic material are provided one above the other. These can each have different Umschlagtemperaturen and should have at least partially different colors. Thus, at different Umtschemperaturen a gradual optical temperature display can be created, which is not only a kind of Bermmêt or Bermmwarppe, but also can display more information about the temperature. Furthermore, an even stronger visual effect can be achieved as a display by means of different colors, so that, for example, multi-colored warnings of thermochromic materials become visible.
  • thermochromic material in an alternative embodiment of the invention, it is possible to provide several layers of at least one thermochromic material and at least one non-thermochromic material one above the other.
  • thermochromic material covers or covers the other layer.
  • An advantageous conversion temperature may be about 50 ° C to 90 ° C.
  • the turnover temperature should be selected so that the color change takes place at temperatures on the top of the cooktop panel in the range of 50 ° C to 70 ° C, which are considered as usual values or limit temperature for a hot indication or residual heat indicator, since from these temperatures and above it a risk of burns when touching the hob plate called limit temperature can be selected for the touch safety. If some space is provided, then it can be assumed that there is a significant temperature gradient of more than 10 ° C or even more than 20 ° C and the limit temperature at the top of the hob then about 70 ° C to 90 ° C on the display device for the Color change as turnover temperature corresponds.
  • thermochromic material is applied to an electrical insulator. This should be advantageous over a large area and the insulator can then be arranged approximately parallel to the hob plate. On the one hand, it is possible to arrange it laterally next to a heating device, which means good visibility of the temperature indicator even when the cooking vessel is set up. When using a radiant heater as a heater, this is recommended, since an arrangement of the temperature display or the thermochromic material would adversely affect both its heating effect and would most likely lead to damage or destruction.
  • the invention is realized with a so-called holding heater, which acts as a contact heater and has electrical resistance heating elements and is applied to the underside of the hob plate.
  • Such holding heater or their electrical resistance heating achieve by far not as high temperatures as radiant heaters.
  • Thermochromic material can then be applied to its upper side, which may be a cover or a support for the resistance heating element, towards the hob plate, as otherwise described, for example as a direct coating or as a sticker.
  • the support for the resistance heating element may be ceramic, for example alumina or the like, or consist of metal with an insulating layer. or as a sticker.
  • the support for the resistance heating element may be ceramic, for example alumina or the like, or consist of metal with an insulating layer.
  • the heating device is an induction heater with an induction coil, as used in cooktops, and then an arrangement of the temperature display is also possible directly above the heater.
  • Such induction coils are usually disc-like, so that the arrangement of the temperature display is well possible.
  • a display located above the heater is basically visible.
  • a temperature display is advantageously large-area, so that it is clearly visible.
  • the top or this insulator disc can serve as a carrier for the thermochromic material of the temperature display.
  • the thermochromic material is thus applied to an already existing component in the form of the insulator disk, for example by a conventional and suitable for a color and the insulator disk method.
  • the thermochromic material to the hob plate and can be particularly advantageous even pressed against this. This has on the one hand the aforementioned advantage of better temperature coupling and avoids the above-described features of the cost of coating the hob plate itself with the thermochromic material. It is possible, for example, as described above, that the thermochromic material has a color change from colored to transparent when a reversal temperature is exceeded, wherein a warning due to overheating is visible through the transparent thermochromic material.
  • the insulator disk has a strong color, for example red.
  • a thermochromic material may be applied, preferably with a prescribed dark color, which may be, for example, blue, black or green. In the above-described color change from colored to transparent when exceeding a Umschlagtemperatur the thermochromic material disappears, so to speak, through the cooking plate through not visible dark thermochromic color and the strong color of the insulator disc is visible as an optical temperature display and especially as a warning.
  • thermochromic material such that it is present as a color below the turnover temperature itself, but because of the dark color design virtually invisible and yet opaque, and becomes invisible only after exceeding the Umschlagtemperatur, has the advantage that it is better for thermochromic material with a dark color to cover an underlying, conspicuous, normal color, which is then ultimately very visible, rather than providing a reversed thermochromic color even with appropriate luminosity or visibility.
  • a thermochromic material with a dark hue can almost better hide a striking hue and then make it visible than it itself by means of a thermochromic material represent.
  • thermochromic and non-thermochromic colors or materials are possible.
  • One manufacturer is the company TMC Ltd. from UK with a CHROMAZONE pigment, see also the alternative EP 1888004 B1 .
  • a sticker or adhesive film may be provided on the one hand with the strong color and on the other hand with the thermochromic material over it.
  • the sticker itself can be kept in the strong color.
  • Such a sticker or such a film can be applied or glued on top of the induction heater, in particular on an aforementioned insulator disk.
  • a standard induction heater can be provided later with a thermochromic sticker and thus only minimal constructive change or additional expense incurred.
  • a film for the adhesive film or the label with appropriate temperature resistance for use directly on induction heating is also known in the art, for example as a Kapton film.
  • the cooktop panel is not only translucent, so that a color must be quite strong or glaring to be perceived through them, but even almost or completely transparent.
  • Such cooktop panels are also made of glass ceramic, such as Eurokera or Schott. Then signal colors directly from thermochromic color are also well usable and well visible through the hob plate for a very versatile temperature display, which also has many possibilities in the optical design.
  • a colored surface can be displayed as a temperature display, but various symbols, words or even company logos or the like.
  • thermochromic material to a support can be effected, for example, by dyeing an aforementioned insulator disk by a dipping process, detached from the respective material.
  • a correspondingly colored ceramic as aforementioned insulator disc can be used, which is so colored with thermochromic material.
  • colored stickers which are either provided with a thermochromic material as a coating on a corresponding film layer or which have a film which has been dyed correspondingly with thermochromic material.
  • spraying and printing processes in particular screen printing and pad printing.
  • thermochromic material of the display is heated directly by the heating device, so that it passes through the turnover temperature. Then either the thermochromic material itself serves as a temperature indicator directly or, as it were, releases an underlying, more noticeable color as a temperature indicator.
  • thermochromic material may be indirectly heated, via the cooktop panel itself heated by the heater. This has the advantage that a temperature of changeover for the thermochromic material will be closer to the limit temperature prevailing for contacting the surface of the cooktop panel can. This also requires a less temperature-resistant thermochromic material.
  • the latter method can be used in particular together with induction heaters, while the aforementioned method is more suitable for radiant heaters or for the holding heater or contact heater.
