During the National Day holiday, I bought a double door refrigerator and planned to transfer the old refrigerator stickers. Unexpectedly, the refrigerator door couldn't hold the refrigerator stickers anymore. "Experienced" backpacker "Xiaolu has traveled around the world and loves to collect local refrigerator stickers as travel souvenirs. She has accumulated a lot of" refrigerator stickers cannot be attached to the refrigerator ", which has left her confused. There are also many similar voices on social media: "The functions of refrigerators have increased, but the refrigerator door has actually 'demagnetized'." When I visited home appliance stores, I found that "refrigerator stickers cannot be attached to refrigerators", reflecting not only the change in materials, but also the comprehensive upgrade of current home appliance products in design, materials, and functions. The small refrigerator sticker reflects the technological innovation in the contemporary home appliance industry and the upgrading of household consumption. A salesperson from a home appliance store in Beijing told me that under the manufacturing process in the past, refrigerator doors were mostly made of iron or stainless steel, which could easily attract magnetic refrigerator stickers. As consumers' demands for functionality continue to increase and the market environment changes, manufacturers are updating and upgrading the materials of refrigerator door panels. Nowadays, more beautiful and functional glass panels have become the second choice besides metal panels. In terms of appearance, glass not only has a bright visual effect and a more fashionable feel, but also has strong stain resistance. In terms of functionality, the smart glass panel that looks like a keyboard can achieve temperature adjustment, child lock, long-term door opening warning, and more. This transformation is not only for the appearance, but also a manifestation of continuous progress in manufacturing processes and technology, and an important step towards realizing intelligent refrigerators. A refrigerator is not just a food storage tool, but also needs to have rich functions and match the overall decoration style of the kitchen and even the whole family. The panel of a glass panel refrigerator can serve as a display screen, which is both attractive and convenient, and more appealing to me than a stainless steel panel A customer in the store said this to me. During the interview, salespeople from multiple stores in the store stated that customers now value home appliances that combine functionality and aesthetics. Taking refrigerators as an example: Based on their preservation function, consumers in the past mostly pursued large capacity and high refrigeration efficiency. Nowadays, the level of intelligence, energy efficiency, materials, and appearance are all taken into consideration. It is understood that currently positioned as high-end and personalized refrigerators, they mostly use smart glass panels, while many mid to low price refrigerators still use traditional panels. The panel is just a 'facade', and in recent years, the traditional household appliance of refrigerators has been constantly upgraded, adding a lot of 'black technology'. Some home appliance companies have launched "active preservation" technology for fruits and vegetables, which adjusts the oxygen concentration through technical means to actively synthesize antioxidants and nutrients in fruits and vegetables, thereby extending the preservation period. Vegetables can be preserved for more than a week. Some high-end products of certain brands offer precise temperature zoning, equipped with functions such as sterilization and purification, rapid freezing, and quick ice making. Since the beginning of this year, the "trade in" policy has helped various new high-performance home appliances enter more households. From a national perspective, a series of supporting measures for the policy of exchanging old for new consumer goods have been implemented one after another, providing consumers with "real gold and silver" subsidies. This not only promotes the prosperity of the home appliance market, but also accelerates the popularization of high-efficiency and energy-saving products. The strong production and sales drive home appliance enterprises to accelerate research and development innovation, launch products with more design and practicality, and promote industry upgrading and replacement. It is reported that since the end of August this year, many local governments have successively issued trade in coupons, including various household appliances, and some refrigerator products have a maximum discount of 2000 yuan per item. According to data from the Ministry of Commerce, as of October 15th, 20.667 million consumers have applied for trade in programs, 10.134 million consumers have purchased 14.624 million household appliances, and enjoyed 13.17 billion yuan in central subsidies, driving sales to 69.09 billion yuan. The relevant person in charge of the National Development and Reform Commission stated that the policy of exchanging old for new consumer goods has indirectly driven investment, efficiency, and output growth in related industries, with household appliances becoming one of the four industries that benefit the most from the policy. According to the value-added tax invoice data released by the State Administration of Taxation, in the first three quarters of this year, retail sales of daily household appliances such as refrigerators increased by 6.5% year-on-year, driven by the policy of exchanging old for new consumer goods.
