China has designed and manufactured household dryers for more than 20 years, but the household penetration rate has been at a low level, and the annual sales volume in the domestic market has remained low. With the improvement of people's living standards and the growing middle class, consumers' demands for quality of life have been continuously improved, which has led to a rapid increase in the sales of dryers in recent years. In 2017, the sales volume of dryers was close to 1 million units, which was more than 40% higher than last year. The sales volume of washing and drying machines increased by more than 80%, which indicates that the industry is about to enter a period of rapid development. The standard system is getting better and better to promote the rapid development of the industry The traditional way of washing clothes in China is an important factor hindering the rapid development of dryers. In addition, the experience of consumers actually using dryers is very small, and the media attention is also small. Therefore, the society has produced some misunderstandings about dryers. It has further limited the expansion of its market size. In order to improve the quality level, fully reflect the use value of products, and promote the increase of family penetration rate, starting from 2006, the National Household Appliance Standardization Technical Committee has begun to establish a quality evaluation system for dryers. After more than ten years of efforts, as of 2017, GB 4706.20, GB/T 4214.7, GB/T 20292, GB/T 22939.5, GB/T 23118 national standards, and QB/T 4685, QB/T 5132 have been established. Industry standards are representative of a relatively complete standard system including electrical safety, health and safety, energy conservation and environmental performance and performance. The establishment of this system has set up a display platform for product quality level, providing technical support for consumers to understand the value of product use, and laid a solid foundation for the development of the industry. Introduction to household dryers and establishment of standard system A clothes dryer is a device that removes moisture from a fabric by blowing, heating or condensing. According to the use and installation methods are generally divided into standing, desktop, wall-mounted, embedded; according to the dry clothes principle is generally divided into straight row (including ventilation cycle, hot air circulation, heat pump), condensation; Generally divided into independent, washing and drying machine. The main performance indicators of dryers are drying efficiency, drying uniformity, power consumption, water consumption, noise, sterilization rate, antibacterial rate, material dissolution, reliability and so on. In addition, its rated capacity refers to the mass (kg) of the fabric that can be dried in one operation as stated by the manufacturer. After more than ten years of hard work, the National Household Appliances Standardization Technical Committee Cleaning Tools Subcommittee has revised and revised more than 10 national and industry standards, and basically established a relatively complete system covering electrical safety, health and safety, energy conservation and environmental protection and performance. The standard evaluation system has played a positive role in promoting quality upgrades and rational purchase of consumers, and has also promoted the improvement of product quality. Advanced standard iteration provides technical support China's household dryers originated more than 20 years ago. At the beginning, only GB 4706.20-2004 "Special requirements for safe drum dryers for household and similar electrical appliances" is a national standard. The standard is also limited to the danger of electric shock and heat. There are four safety requirements for hazards, mechanical hazards, fire hazards, and toxic radiation hazards, and there are no standards for performance. Therefore, the basic characteristics of the product can not be directly reflected, and it is impossible to distinguish the cost performance of the product, so that neglecting the performance quality of the product gradually becomes a common problem in the industry, and makes consumers more aware of the performance, which seriously affects the development of the industry and makes the annual sales of the dryer. It has been hovering at a low level of more than 100,000 units, which is extremely incompatible with the rapid development of the home appliance industry. On July 1, 2007, the first national performance standard for dryers, GB/T 20292-2006, was implemented, which made the product display performance quality reliable. On September 1, 2009, GB/T 23118-2008 national standard for performance grading of washing and drying machines was introduced, and the quality target was stipulated. The standard classifies the technical requirements of drying uniformity, power consumption, water consumption, noise and other projects. Among them, the A grade is the international advanced level, the B grade is the domestic advanced level, the C grade is the domestic medium level, and the D grade is the qualified level. The emergence of grading technical requirements has led to the previous quality control based on electrical safety, and began to shift on the basis of ensuring electrical safety, and the performance quality should be developed in the same direction, which makes the performance quality of dryers in China have improved qualitatively. , thereby promoting consumer understanding of the quality of performance. After entering the 21st century, the household appliance industry began to pay attention to the sterilization and antibacterial properties of the products. Before the introduction of the GB21551 series of household antibacterial and sterilizing national standards, the antibacterial and sterilizing ability of the products could not be scientifically demonstrated, which made some claims have antibacterial and antibacterial capabilities. The goods appear on the market. Since there is no standard to identify the level of sterilization and sterilization, it has caused great confusion to consumers, and it has also increased the uncertainty of market competition. In 2010, GB21551 national standards for antibacterial and sterilization series were successively introduced, which made the concept hype effectively curbed, thus promoting the rapid development of healthy household appliances. On October 1, 2017, QB/T 5132-2017 "Technical requirements and test methods for antibacterial and sterilizing functions of household and similar dryers" - China's first household appliance antibacterial and sterilizing industry standard was officially implemented. The standard requires that the antibacterial rate and sterilization rate of the dryer should be not less than 99.0% and 99.9% respectively. At the same time, the standard gives the technical requirements for the amount of harmful substances in the materials such as rollers, so that the technical requirements of the dryers in terms of health and health have reached the international advanced level. This technical requirement and test method have also been adopted by the International Electrotechnical Commission (IEC) as a reference for drafting international dryer standards. In the current dryer standard system, GB 4706.20, GB/T 4214.7 and GB/T 20292 are equivalent to the IEC standard of the International Electrotechnical Commission, that is, in terms of electrical safety and performance testing methods, China's standards are consistent with the standards of developed countries. Reach the international advanced level. GB/T 23118, QB/T 4685 is the performance performance standard formulated according to the characteristics of China's products. It means that the technical requirements and test methods of China's standards in drying efficiency, electricity consumption, noise, etc. have also reached the international advanced level. In particular, the standard has classified the main performance technical requirements such as drying performance, drying uniformity, electricity consumption, water consumption, noise, etc. The highest grade A has reached or is close to the international advanced level, which shows the performance of China's dryers. Moving towards the international advanced level. The introduction of these standards has pointed out the direction for the quality upgrade of dryers, laying a technical foundation for the individualized development of products. Therefore, it has greatly promoted the rapid development of the industry and provided a reference for consumers to purchase. At present, China's clothes dryers have entered a period of rapid development. With a complete standard evaluation system as technical support, dryers will develop in a fast, orderly and healthy direction. It is foreseeable that the ownership rate of dryers in ordinary households will be greatly improved in the next five years. Technology development speeds up the trend of high-end The "Nineteenth National Congress" of the Party put forward the idea of ​​building a "beautiful China" and embodied the harmonious beauty of scientific development. "Beautiful China" pointed out the specific way of scientific development and pointed out the beautiful vision of economic and social development. The construction of “beautiful China†indicates that the whole society should abandon uncivilized lifestyles and behaviors. The way of “roaming clothes on the balcony†will gradually change, and the quick, comfortable and healthy drying methods of dryers will gradually be accepted by consumers. With the construction of “beautiful Chinaâ€, the dryer will enter a period of rapid growth. The performance indicators such as drying effect, electricity consumption, water consumption, drying uniformity, noise and service life will be paid attention to by consumers, and high-performance quality will become consumption. The goal of chasing, high-end will become the mainstream of industry development. In order to adapt to the transformation and upgrading of China's home appliance industry and the development of high-end products, we should encourage technological progress and catch up with the world's advanced level, improve the comprehensive competitiveness of products, and provide reference for consumers to purchase. The China Household Electrical Appliances Research Institute and the Beijing China Lightlink Certification Center jointly launched the “A+†certification with higher performance indicators than the A-level, thus establishing a platform for high-end dryers to demonstrate design and manufacturing technology, creating an understanding for consumers. The channel of product quality, product performance and quality certification will effectively promote the improvement of product quality and promote the orderly development of the industry.
