China Consumer News Beijing News(ReporterSang XueqiOn November 29th, the 2023 China Health Home Appliance Conference hosted by Zhongjiayuan (Beijing) Testing and Certification Co., Ltd. was held in Beijing. The forum was held online and offline with the theme of "Certified Sleep Aid · Health Companion". The meeting showcased 7 advantageous products that have obtained the first batch of CHCT "Sleep Grade Low Noise" certification in 2023.
"From the initial establishment of a health appliance evaluation system, to the launch of health index certification, and now that mandatory national standards for health and safety are about to be introduced, the health appliance industry has developed rapidly." Zhang Xiao, deputy director of the Testing Institute of the China Household Appliances Research Institute, pointed out that the development trend of health appliances in the future will eventually move towards scene evaluation, towards the evaluation of people, and sleep is one of the most important household health scenarios. Factors such as sound, light, temperature and humidity that affect sleep are closely related to home appliances.
According to reports, in 2021, the China Home Appliance Research Institute, as a pilot unit, undertook the national household appliance consumer product standardization pilot project (smart and healthy home), and sleep assistance was also one of the key research topics.
Chen Yanbo, a PhD from the Institute of Pattern Recognition at Beijing University of Technology, said that sound, light, color, temperature, smell, etc. are all factors that affect the sleep environment. An individual’s emotional state also has an impact on sleep, and it not only directly affects sleep quality, but also largely shapes people’s perception of the surrounding environment.
It is reported that the China Home Appliance Research Institute and the China Standardization Association have approved two group standards, "Technical Requirements and Test Methods for Sleep Assisting Functions of Air Conditioners" and "Technical Requirements and Test Methods for Sleep Assisting Functions of Massage Chairs", to promote the development of the home appliance industry in the direction of healthy sleep assistance. For the first time this year, CHCT "Sleep Grade Low Noise Certification for Household Appliances" was launched, aiming to take an important step in the evaluation of sleep scenes from the perspective of noise. Zhang Weichao, deputy director of the Health Appliance Testing Center of Zhongjiayuan (Beijing) Testing and Certification Co., Ltd., explained that the sleep assistance function of an air conditioner refers to the improvement of environmental conditions such as temperature and humidity, airflow, sound, light, and smell, so as to assist in creating a better sleep environment and help users fall asleep or improve sleep quality. Its core technical indicators mainly include noise, air supply function, comfort, display light source, temperature and humidity control function, odor release, air purification, fresh air function, and sleep assistance substances. The sleep assistance function of a massage chair refers to the function of relying on mechanical pressure, air bag pressure, material magnetism, and electric heating to act on certain parts of the human body, thereby helping users fall asleep or improve sleep quality. The core technical indicators mainly include heating function, magnetic function, odor release, and special functions. Cradle mode, pressing feet, shoulder and neck massage and whole body stretching massage, etc.). "The formulation of these two standards has given specific quantitative indicators for the sleep assistance function of home appliances, and opened up the road for the sleep assistance field of home appliances," Zhang Weichao said.
Chen Songtao, director engineer of the Health Home Appliance Testing Center of Zhongjiayuan (Beijing) Testing and Certification Co., Ltd., said that the "sleep-level low-noise" certification of home appliances is designed to meet consumers’ growing requirements for sleep scenes and quality of life. It places strict requirements on the noise in the life scenarios of home appliances, and it is necessary to ensure the basic performance indicators of home appliances under the premise of low noise. At present, the certification covers humidifiers, fresh fans, air purifiers, dishwashers, washing machines, clothes dryers, electric clothes dryers, electric toilets, and cleaning robots. The product categories will continue to expand in the future. " The certification implementation rules specify the corresponding technical requirements and test methods for each product, and the index requirements are more stringent, and they are set according to the characteristics of the product. "Chen Songtao said.
In addition, *******, director of the Secretariat of the Health Care and Similar Appliances Sub-Technical Committee of the National Household Appliance Standardization Technical Committee, said that the formulation of three mandatory national standards, "Household and Similar Appliances, Electrical Appliances Safety Specifications", "Household and Similar Appliances, Energy Conservation and Environmental Protection Specifications" and "Household and Similar Appliances, Health and Safety Specifications", is in the final stage. These three mandatory national standards will replace more than 100 current mandatory standards for home appliances. Among them, the health and safety standards are streamlined and integrated with GB 21551 series standards, GB 17988 and GB 19606 standards, and the technical indicators are mainly divided into two directions. On the one hand, it is health and safety, including ultraviolet leakage, noise, electromagnetic radiation (EMF), ozone leakage, TVOC concentration, and hygiene and safety of food contact materials. On the other hand, it is health protection function, which currently mainly involves air purification, sterilization, virus removal, antibacterial and antifungal materials, and antiviral materials.
"Home appliance consumers pay more attention to quality and price ratio, and consumer demand is also showing a polarized trend. Therefore, the development of healthy home appliances needs to identify the segmented needs of consumers." Wang Hongji, general manager of the white electronics business department of Beijing Zhongyikang Times Market Research Co., Ltd., believes that the trend of integration of home appliances and home improvement is becoming more and more significant, and in the future, healthy home appliances need to implement healthy functions in the scene. In the future, healthy home appliances will show effective integration with intelligence, integration with energy-saving products, high-end products, partition washing, and healthy and clean home appliances. There are seven development trends of refrigerator sterilization and preservation, and healthy sterilization and air conditioning.
