In a recent interview, Lu Jianguo from the National Household Electrical Appliances Quality Supervision and Inspection Center revealed that the "Standard Test Method for the Performance of Household Drum Dryers" has been submitted to the National Standards Committee and is expected to be officially released within the year. This new standard aims to establish testing criteria for key performance indicators such as drying efficiency, energy consumption, water usage, and drying uniformity.
This development aligns with the earlier "Automatic Washing and Drying Machine Standard" introduced by the China Association for Standardization on April 12th, which also covers similar aspects. However, while both standards are voluntary, they serve different purposes. The new testing method focuses on evaluating performance metrics, allowing manufacturers to voluntarily test their products and label them accordingly. On the other hand, the "association standard" sets specific limits on drying efficiency, energy use, and water consumption, such as a maximum drying rate of 97% and an electricity consumption limit of 0.3 kWh per kilogram.
Moreover, the association standard incorporates Haier’s JIT (Just-In-Time) clothing drying technology, emphasizing the importance of intelligent drying systems. Despite these advancements, neither standard is mandatory, meaning manufacturers can choose whether to adopt the technology or follow the guidelines.
According to Lu Jianguo, the lack of a mandatory standard stems from the immaturity of current drying technologies. Many manufacturers still face challenges in integrating drying functions into washing machines, resulting in low drying efficiency and longer drying times. As a result, setting enforceable benchmarks remains difficult.
Industry reports indicate that the drying capacity of most washing and drying machines is significantly lower than their washing capacity. For example, a 6 kg washing machine may only handle 3.5 kg of drying, and some models even less. Additionally, the drying process can take up to two hours for a 3.5 kg load, highlighting the need for technological improvements.
Currently, only a few brands, including Haier, LG, Siemens, Bosch, Panasonic, and Sanyo, offer washing and drying machines in the market. Most companies have limited product lines, suggesting that the market is still in its early stages.
Despite these challenges, industry experts believe that washing and drying machines represent the future of drum washing technology. Haier reported a more than 300% increase in sales during the May Day holiday, particularly in major cities like Beijing, Shanghai, and Guangzhou. Similarly, LG noted a 250% year-on-year growth in its intelligent drying machines in the domestic market.
The introduction of these two standards signals a shift toward smarter, more efficient drying solutions. Experts emphasize that intelligent control—such as real-time monitoring of temperature, humidity, and drying time—is crucial for improving drying uniformity and protecting fabrics. Traditional dryers often rely on fixed timers, which can damage clothes over time. In contrast, smart systems adjust based on actual conditions, offering better results and reducing wear and tear.
While the standards are not legally binding, they provide consumers with clear benchmarks to make informed purchasing decisions. Consumers are advised to prioritize models with large capacities, advanced drying features, and intelligent control systems to ensure better performance and longevity.
As the market continues to evolve, the integration of smart technology will likely play a central role in shaping the next generation of washing and drying machines.
