Description

Technical Field

[0001] This utility model relates to the technical field of kitchen storage utensils, specifically to a double-layer sink rack used on a sink. Background Technology

[0002] Currently, most tableware in households is stored on shelves. Even after washing, water stains remain on the tableware. To prevent water from accumulating on the countertop, shelves usually have drip trays to catch drippings, but users need to empty these trays frequently. Later, people simply placed the shelves on the sink, eliminating the need for drip trays and emptying. However, these shelves are typically made of welded stainless steel, resulting in significant weight and size, leading to high packaging and transportation costs and limiting their export competitiveness.
