Since March 2005, the market battle for washing and drying machines (drum dryers for household use) has been on the rise, especially in the high-end drying technology. First of all, Haier launched its image model, the Sunshine Beauty Washing Dryer, at the same time, and announced the launch of the "Year of Drying Strategy." Then Siemens, Electrolux, LG, Samsung and other giants followed suit.
However, the high price plus the technical disputes of the various executives, the marketing of the washing and drying machine is not satisfactory. Based on this status quo, the national standard for domestic tumble dryers is currently being developed and is expected to be introduced this year to regulate the market and guide consumption.
"Background: Washing and Drying Machine is not "appetizing""
“Sichuan is located in a basin with damp weather, especially in Chengdu, where winter is almost always cloudy and rainy. Clothes can't dry, and cotton clothes can even appear wet and smelly. Not only can clothes that are not dry enough to wear uncomfortable, It may also cause skin discomfort. Even if the clothes get sun, they are easily contaminated and cause health hazards.†Siemens washing machine sales staff recommend the washing and drying machine. “As the living standards improve, the washing and drying machine will become the home appliance sales. "The new darling of business and ordinary consumers."
However, although the technology of drying washing machines is very popular in foreign countries, the reporter found during the investigation that in the major shopping malls and home appliance stores in Chengdu, the washing and drying machine did not have a good reputation. Some users complained about the inconvenience or inconvenience of the washing machine.
"Evaluation: standard introduction of standard market"
On the one hand, there is a phenomenon of "difficulties in soil and water" in the dryer. On the one hand, the major manufacturers are vigorously promoting their own drying technology.
Taking the drying method as an example, Lu Jianguo, director of the laundry department of the China Household Electrical Appliances Institute, interviewed by reporters pointed out that there are three main types of drying technology on the market: natural air drying, heating drying, and condensing drying. Dry, heating and drying are divided into electric heating pipe heating, PPC heating. It is understood that the drying drum machine on the market currently uses condensation drying technology.
Minister Ma of Duckling Washing Machine Technology Division said that the principle of drying is actually the process of ventilation, heating, and dehumidification. Specifically, the principle of the heating drying is to heat the moisture remaining on the clothes after being heated. The condensing and drying technology is one more process, and the hot water vapor is condensed into a liquid. “In general, the heating of cotton clothes can be dried more thoroughly. The condensing drying has changed the past dryers alone to blow the hot air to dry clothes, thereby reducing the damage of clothes caused by hot drying. In addition, condensation-dried clothes have fewer creases."
"Three types of drying technologies have their own advantages and disadvantages. However, because there are no standards to measure, there are cases where manufacturers falsely publicize and attack each other." Lu said, "The introduction of national standards will serve to regulate the market and guide consumption. Once the standard is introduced, manufacturers and consumers will all have a measure of scale, and manufacturers will not be able to brag about themselves, and the credibility of information that consumers obtain will also increase."
"Regret: The standard only specifies the test method."
Lu Jianguo also disclosed that the new standard for drying washing machines currently being drafted is in accordance with the International Electrotechnical Commission's IEC 61121 (2002-07) version of "Testing Methods for Performance of Household Drum Dryers", which will standardize the drying time and power consumption of washing machines. The water consumption, drying efficiency, and the degree of drying after the clothes are dried are defined. It is expected that it will be implemented starting next year.
“Simply put, it is to specify the number of kilograms of clothes that can be dried at one time under standard conditions. Different dryers must achieve a certain amount of moisture after drying, and with less electricity, the drying efficiency is high. ."
Director Lu said that the standard is mainly aimed at several currently controversial indicators, one is the drying time, the market part of the washing machine uses a timer drying principle, but also need to manually adjust the drying time, Once set, it must be run in a fixed time mode. This can easily lead to baking occasionally, and sometimes cases of bad clothes often occur.
The second is dry uniformity. Traditional dryers use a constant temperature timer to control the drying time. Regardless of the degree of dryness and humidity of the clothes, they are fixed drying temperatures. The clothes are easy to damage fibers, fade, and the more drying times, the faster the clothing damage. In addition, this kind of dryer has only one kind of drying mode, cotton and chemical fiber must be separately dried, it is easy to cause the unevenness of drying, so the evenness of drying may also include the clause of the performance experiment.
Washing, drying integration technology, standards into a "stumbling block" (1)
"Washing and drying are combined, washing my beloved clothes, eliminating the trouble of drying in my life, and life is becoming easier than ever before. I want to enjoy it from now on." This is a brand of appliances launching a dry wash. An advertising message played on one machine.
