Embodiment Construction

[0042] Such as Figure 4 As shown, the cooking device according to the present invention includes a heating element 10, a glass ceramic panel 20, a touch sensor 30, and a 7-segment light emitting display element 40. Among them, the touch sensor 30 and the light-emitting display element 40 are placed under the glass ceramic panel 2. The light-emitting display element 40 is preferably a 7-segment display LED, which can be a dot-shaped or linear-shaped LED, and the display pattern is preferably a letter, number, or symbol. In addition, the glass ceramic panel 20 includes a glass ceramic substrate 200 having a smooth upper surface 201 and protrusions 202 on the lower surface side. Therefore, the glass ceramic substrate 200 includes valleys 203 between the protrusions. In addition, such as Figure 5 As shown, the glass ceramic panel 20 according to the present invention includes a filter film 205 adhered to the underside of the glass ceramic substrate 200 for color compensation. Th...

Abstract

The invention provides a glass ceramic panel and a cooking device with the same. The glass ceramic panel comprises a glass ceramic base plate, a transparent adhesive layer and a filter coating, wherein the glass ceramic base plate is provided with a smooth upper surface and protrusions on the lower side surface, the transparent adhesive layer is located below the glass ceramic base plate, and thefilter coating adheres to the glass ceramic base plate through the adhesive layer. According to the glass ceramic panel and the cooking device with the same, the adhesive layer is pressed into concavevalleys formed among the protrusions so that light beams from the part below the glass ceramic panel can be uniformly transmitted to the upper side of the glass ceramic panel from the glass ceramic panel without color shift; and under the circumstance, the light beams viewed from the upper side of the glass ceramic panel do not generate the color shift.

Description

Technical field [0001] The invention relates to a glass-ceramic panel and a cooking device with the glass-ceramic panel. The glass-ceramic panel has a filter sheet to avoid or at least reduce the color shift or distortion caused by the light emitted from under the glass-ceramic panel. Background technique [0002] Black glass ceramic cooking panel, such as CERAN It has protrusions on the lower surface side to increase the damage resistance of the cooking panel. [0003] During the production and installation of the glass ceramic cooking panel, it only comes into contact with other materials, such as oven brackets, conveying rollers, packages, etc., at the top of the protrusions, not in the valleys between the protrusions. Therefore, possible damage, such as scratches caused by contact with hard materials, is limited only to the top of the protrusion. The tops of these protrusions form only a small part of the entire surface of the glass ceramic panel. Therefore, the overall mech...
