The antibacterial test label is still not attached to the household appliances sold for sale.

As there are no relevant standards, the promotion of sterilization appliances has always made consumers “confusing”. In order to reverse the market chaos of self-resolving household appliances, in the middle of last month, compulsory national standards for antibacterial appliances were formally implemented, and standards set stringent requirements for the sterilization of home appliances such as refrigerators, washing machines, and air conditioners. How is the implementation of this standard? Reporters recently visited the Dongguan market and found that the current sterilization of home appliances sold basically did not put a sign of detection, home appliances sterilization is still the business has the final say, in the face of business propaganda, consumer choice is still "Monday."

There are many kinds of "sterilization" claims

The reporter recently visited the urban appliance stores and found that there are not a few household appliances propagating with “sterilization technology”. "There are many refrigerators with sterilization function, such as the use of UV, ozone and other sterilization technology." In the Hong Fuk Road, a store sales area, the sales staff introduced a brand refrigerator to the reporter, said these The sterilization technology can effectively kill the bacteria in the refrigerator and on the food surface. Then another refrigerator was introduced. The silver ion sterilization technology was used, and imported sterilization materials were used in door seals and other places.

Looking at the overall market situation, although various types of sterilization technology were blown up by businesses, when reporters asked if they had relevant certificates or certifications, many brands claimed that they were not available for the time being. Even if some brands can produce relevant certificates, however, The technical certification bodies displayed in the certificates are also varied, and these institutions are often not well-known to consumers.

Similarly, in the field of washing machines, many brands have also introduced various types of sterilization products, such as a brand of silver ion sterilization automatic series.

The price difference of similar products

The reporter found that as long as the sterilization function comes into contact with, the value of home appliances will rise. A washing machine with a washing capacity of 6 kilograms is a foreign-style washing machine with drying, quick washing and other functions. The price is about 5600 yuan. Another washing machine with the same capacity, the same material, and the same function only has more sterilization function. The price is 7200 yuan, the price difference between the two 1600 yuan.

"This kind of sterilization function uses a new sterilization technology." Sales personnel said that this new technology can destroy the ability of bacteria to multiply in a short time by injecting technologies such as water flow containing silver ions during the rinsing process. Kill the bacteria to achieve the purpose of sterilization.

"The refrigerator with sterilization function is nearly 2,000 yuan more expensive than a refrigerator without this function." A foreign-brand refrigerator salesman told reporters that the product prices of sterilization products are generally higher from the point of view of washing machine products sold in stores.

In addition to the higher prices, there are many restrictions on the use of such sterilization products. For example, the sterilization function of many products is to kill attached bacteria through high-temperature cooking, and this high temperature generally reaches above 90°C, and can only be used in drum washing machines. In addition, high-temperature sterilization is also limited to the clothing of specific fabrics. . Some people in the industry pointed out that the principle of sterilization of some products is ozone sterilization, which has requirements for environmental humidity and other aspects. If it is not properly handled, it will be counterproductive.

New logo appliance not listed

Sterilization products are numerous and varied, in order to reverse the market chaos of self-resolving household appliances, on September 15, the national standard for sterilization, sterilization of home appliances - "Antimicrobial, sterilization and purification of household and similar electrical appliances" The special requirements for functional refrigerators are formally implemented. The standards set stringent requirements for the sterilization of home appliances such as refrigerators, washing machines, and air conditioners. After the implementation of the standard, the related sterilized products must meet the standards and obtain the qualification certificate issued by the certification body designated by the National Standards Committee before they can be listed, and a qualified mark will be posted on the appearance.

According to industry insiders, the implementation of this standard will have the effect of purifying the sterilization product market. Consumers will no longer be confused when they choose such products.

However, as of today, the standard has been implemented for more than a month, and the reporter did not find any sales of products with related marks. The answer given by the salesperson is that soon after the introduction of the new regulations, it will take time for the new standard products to be listed.

As a result, although the newly marked Taiyueyu, Dongguan consumers still “sweeped” when buying sterilized products. “I want to buy a refrigerator with a strong sterilization function, but it is too difficult to choose.” Recently, Miss Xiao who lives in Dongcheng told reporters that her children are more than two years old and like to eat snacks, but children’s resistance Weak, afraid that he had bad things, so he wanted to buy a sterilization function refrigerator and a sterilization function washing machine.

Although the neighbors strongly recommend their own products with the same model, but because they do not understand this aspect, so Miss Xiao went to a few home appliances store in the East City, a walk away, but fortunately, after a stroll found it more difficult to choose Now. “Each salesperson says that his products are good, and some can still come up with relevant certificates. In the end, what should you choose?” Ms. Xiao is very confused in the face of complicated propaganda. Industry insiders reminded that if it is not particularly anxious, it is recommended that home appliances with new logos be listed and then buy fungicidal appliances. “With the standard, we are not afraid of being fooled by businesses.”

Common sterilization technology

High temperature sterilization

High-temperature sterilization technology is to heat the water to a certain temperature, the protein in the bacteria denatured and coagulated at high temperatures, causing the death of bacteria. The use of high temperature to remove bacteria is a traditional method of sterilization. Most bacteria in the 55-60 °C high temperature after 30-60 minutes after the decrease in activity and decline; heating to 80 °C after 5-10 minutes to kill part of the bacteria propagules.

Ozone sterilization

The principle of aseptic technology on microorganisms can be divided into three kinds: antibacterial, bactericidal and bacteriolytic. Ozone sterilization is bacteriolysis and is the most thorough form of the three sterilization methods. The so-called bacteriolysis can achieve the effect of “completely and permanently eradicating all microorganisms on the surface of objects”.

Air wash sterilization

Air washing technology is the use of ozone sterilization principle, the air is converted to a certain concentration of ozone, and then act on the clothing, and continue to air circulation, completely kill all kinds of bacteria immersed in the clothes.
