Description

Technical Field

[0001] The utility model belongs to the technical field of porcelain cast iron stove racks, in particular to a combined enameled cast iron stove rack. Background Art

[0002] An enameled cast iron stove stand is a stove support used in home kitchens, primarily for supporting cooking appliances such as gas cooktops and induction cooktops. Enameled cast iron stove stands are based on cast iron, a material widely used in stove stand construction due to its one-piece molding, strong integrity, and high-temperature resistance. A layer of enamel is applied to the cast iron surface, which is then sintered at high temperatures to create a strong bond. This enamel coating not only looks beautiful but also imparts corrosion resistance, wear resistance, heat resistance, non-toxicity, and ease of cleaning.

[0003] Traditional enameled cast iron stove racks become stained with oil and dirt over time. Because the enameled cast iron stove racks are a one-piece structure, cleaning the corners of the enameled cast iron stove racks is difficult. To address this, we propose a modular enameled cast iron stove rack. Summary of the Invention
