Drying Machine Standard Initiates Controversy in Drying Technology

Recently, the Ministry of Inspection and Quarantine of the National Household Electrical Appliances Quality Supervision and Inspection Center Lu Jianguo disclosed to reporters that the "Standard Test Method for the Performance of Household Drum Dryers" has now been submitted to the National Standards Committee, which will surely be introduced within the year and is expected to be implemented by the end of the year. According to Lu Jianguo’s introduction, the standard mainly stipulates the testing standards for dry clothing ratio, electricity consumption, water consumption, and drying uniformity. It can be seen that this is related to the “automatic transmission†promulgated by the China Association for Standardization on April 12th. There is a lot of similarities in the Standard for Washing and Drying Machines. Then, does the introduction of the testing standard mean that there will be two standards in the dryer integrated machine market?
Non-mandatory standards According to Lu Jianguo's introduction, the "Standard Test Method for Performance of Household Drum Dryers" issued this year mainly tests the indicators in four aspects: Drying Rate, Electricity Consumption, Water Consumption, and Drying Uniformity.
He stressed that the standard does not specify any limit value. It is only used for testing. The washing machine manufacturer can voluntarily take the washing machine with drying function to the corresponding testing agency, perform testing according to this standard, and then mark the four indicators. .
"Automatic washing and drying machine standard" is also the industry's self-discipline standard, and people in the industry call it the "association standard." In an interview with this reporter, relevant persons from the China Standards Association stated that the standard has set limits on dry clothes, electricity, and water consumption. For example, the drying rate is not more than 97%, and the electricity consumption is not more than 0.3. Degree / 1 kg, water consumption is not more than 15 liters / 1 kg.
In addition, the "Automatic Washing and Drying Machine Standard" also incorporates Haier's independently researched and developed clothing and dry stop (JIT) technology, emphasizing the requirement of the washing and drying integrated machine in the intelligentization of automatic drying technology. However, as its nature exists, it is not a mandatory standard. Washing machine manufacturers may not use this technology.
From this perspective, there is no conflict between the two, because they are both voluntary standards, the former is manifested as the voluntary testing; the latter is expressed as the voluntary use of technology. In other words, the former is the testing standard of the washing and drying machine, and the latter is the technical standard of the washing and drying machine.
Drying technology is still immature Lu Jianguo said in an interview with this reporter that the reason why there is no mandatory standard for drying washing machines is because most of the current manufacturers of dry clothes technology is not mature, dry clothes and laundry functions Together, the structure is relatively limited, resulting in low drying efficiency, less drying and longer drying times. As a result, the formulation of standards will be difficult to control.
When interviewing a home appliance store in Beijing, the reporter learned that the drying rate of the washing and drying machine is generally low. Generally, the washing machine with 6 kg washing capacity has a drying capacity of 3.5 kg, and some are even less. Half the amount of washing.
At the same time, the promotion staff of the washing machine counter also stated that the drying speed of current dryers is slow, and the drying amount of 3.5 kg needs at least 2 hours.
In addition, according to the reporter's observation, there are not many washing machine manufacturers currently pushing the washing and drying machine on the market, mainly Haier, LG, Siemens, Bosch, Panasonic, Sanyo and other brands, in addition to Haier's main models, Other product models pushed by other manufacturers can only have a maximum of 1-2 models.
The standard indicates the direction of intelligence The relevant personage of the Haier drum washing machine believes that although the drying market is not yet prosperous, it is undeniable that the washing and drying machine will be a direction for the development of the drum washing machine in the future.
According to Haier, during the May Day period, the retail volume of Haier Sunshine Beauty Washing Machine increased by more than 300% year-on-year. Especially in Beijing, Shanghai, Guangzhou and other big cities, the sale of washing machines has formed a climate.
Li Tinghan, vice president of digital home appliance marketing at LG Electronics (China) Co., Ltd., said in an interview with this reporter that a drum washing machine with a drying function is a leap in the washing machine industry. It is believed that in the next few years, the drying function is expected to become standard on drum washing machines.
According to Li Tinghan, at present, LG's drying and drying machine with intelligent drying function has entered a stage of high-speed growth in the domestic primary and secondary markets, with an increase of more than 250% compared with the same period of last year. It is also understood that drum washing machines have entered a large-scale heavy-duty stage in markets with high drum penetration rates in Europe and the United States.
The introduction of the two standards for the washing and drying machine has also demonstrated that the Chinese washing and drying machine market is about to usher in development. At the same time, it can be seen from the contents of these two standards that the future washing and drying machine will emphasize intelligent control more.
Li Tinghan and other professionals believe that the key technology of the washing and drying machine is how to achieve intelligent control, such as all-round monitoring of drying time, drying temperature and humidity of clothes. It is understood that the "automatic washing and drying machine standard" will JIT clothing dry stop technology is included in this consideration.
The "Testing Method for Performance of Household Drum Dryers" issued during the year emphasizes the importance of "dry uniformity" as well as intelligent control. Experts said that the traditional drying machine uses a constant temperature timer to control the drying time. Regardless of the degree of dryness and wetness of the clothes, they are fixed and dried. The clothes are easy to damage the fibers, fade, and the more drying times, the faster the clothing is damaged.
In addition, this type of dryer has only one drying mode, and cotton and chemical fiber must be separately dried, otherwise it may cause uneven drying. Intelligent control will effectively improve the drying uniformity.
The industry believes that although both standards are not mandatory standards, these two standards show the same direction for consumers, and consumers therefore have a standard reference.
Editor's Reminder Since there is still a bottleneck in the drying time and capacity of the current washing and drying machine, it is recommended that consumers choose a large capacity washing and drying machine as far as possible when purchasing. Considering the performance of the dryer in terms of dryness evenness, consumers are advised to purchase products that use intelligent control technology, as well as a variety of drying dryers to choose from.
