Description

Technical Field

[0001] The utility model relates to the technical field of household appliance manufacturing, in particular to a refrigerator drawer which prevents odor from spreading. Background Art

[0002] The design and manufacture of refrigerator drawers are an integral part of the home appliance industry, and their origins can be traced back to refrigerator manufacturers' product development processes. Refrigerator drawer design takes into account user convenience, food freshness, and product durability. Manufacturers design drawers based on market research and technological innovation to meet diverse consumer needs. For example, Haier refrigerators use imported PS material for their drawers, which offers excellent load-bearing capacity, seamless joints, and easy cleaning. Furthermore, with technological advancements, some refrigerator drawers now incorporate vacuum technology for even better freshness preservation. The design and material selection of refrigerator drawers are the result of refrigerator manufacturers' continuous innovation in meeting functionality and user experience.

[0003] Odor-preventing refrigerator drawer technologies primarily stem from innovative designs and technological developments by refrigerator manufacturers. These technologies include independent refrigeration systems, efficient odor removal technology, and specially designed drawer structures, all designed to reduce or eliminate odor contamination between different ingredients within the refrigerator. For example, the TCL Gewu Q10 refrigerator features three independent cooling systems, achieving relative independence between compartments and effectively preventing odor contamination. Furthermore, some refrigerators utilize GP+ photoelectric ultra-clean technology, combining physical isolation and electronic techniques to further control the internal environment and reduce odor and odor contamination. The development and application of these technologies have enhanced refrigerator freshness preservation and user experience.

[0004] After searching, it was discovered that Chinese patent application number / publication number CN109708421B discloses a refrigerator drawer. The drawer includes a PCB, a projection board, and a sensor. The PCB and projection board are fixed to the upper side of the upper cover. The upper cover and the upper baffle are fixed by plugging and snapping. The sensor is fixed to the outer frame to sense the opening and closing of the refrigerator drawer. When the refrigerator drawer is closed, pressing any of the pressing areas illuminates the corresponding pressing area and the corresponding icon. When the refrigerator drawer is open, pressing any of the pressing areas illuminates the corresponding pressing area, while the corresponding icon does not. This makes the structure more stable and easy to install during assembly, while also facilitating subsequent maintenance. During use, it prevents users from overlooking the illuminated area during daily operation of the refrigerator drawer, resulting in a good visual effect, a good user experience, and a strong sense of technology.
