The patent application outlines a cooktop design that incorporates white ceramic glass with unique surface characteristics. The ceramic glass is characterized by a series of micro recesses and embossed portions, which enhance its cleaning efficiency and scratch resistance. The micro recesses have an average depth of 30 μm or less, while the embossed portions range from 80 μm to 130 μm in width. These features contribute to a surface roughness of 1.5 μm to 2.5 μm, optimizing the material for use in cooking devices.
The innovation pertains to the field of ceramic glass technology, specifically focusing on white ceramic glass used in cooktops. The goal is to address the challenges associated with maintaining scratch resistance and ease of cleaning in white ceramic glass, which traditionally underperforms compared to black or transparent variants. This invention provides a solution by modifying the surface structure to enhance its functional properties.
The method for manufacturing the white ceramic glass involves a multi-step surface treatment process. Initially, elastomer particles are blasted onto the glass surface, followed by exposure to a hydrofluoric acid solution for etching. The etched surface is then polished to achieve the desired micro recesses and embossed portions. This process not only refines the surface texture but also integrates a beta-spodumene crystal structure, which is crucial for achieving the desired mechanical properties.
The white ceramic glass can be chemically reinforced to further enhance its durability. It may also feature a through hole for accommodating display devices, with edge reinforcement areas to prevent damage around these openings. The glass's surface may be treated with various elastomer particles, including silicon elastomer coated on materials like aluminum oxide or silicon carbide, to improve its resilience and performance.
This advanced white ceramic glass is particularly suited for cooktops, providing a robust and aesthetically pleasing surface that is easy to maintain. The integration of a display device through the glass extends its functionality, making it suitable for modern kitchen environments. The enhanced scratch resistance and cleaning efficiency ensure longevity and ease of use, meeting the demands of both consumers and manufacturers in the cooking appliance industry.
