Don't think that throwing dirty clothes into the washing machine, you can clean it by pressing a button. Have you ever thought that those clothes are washed unhealthy? In the current market, various brands of washing machines are competing to launch a variety of "healthy washes". Ozone wash, high temperature wash, electrolytic wash, silver ion wash, etc., enough to dazzle you, do you have enough judgment to accurately purchase?

Professionals remind that for the current "healthy wash", there is no uniform mandatory standard in the industry. When consumers buy, it is best to check whether their sterilization effect has obtained the authority certification, so that you can know what to expect. .

Washing health, how to wash?

First, laundry electrolysis water ozone water disinfection of clothes

In real life, bacteria are everywhere, even refrigerators with low temperatures can't inhibit the growth of bacteria, and washing machines that often deal with dirty clothes are even more difficult to "get alone." Relevant tests have shown that the contaminated washing machine contains Escherichia coli, Staphylococcus aureus or even Pseudomonas aeruginosa, Streptomyces griseus, Spider's bacterium, and Cryptococcus erythematosus, which makes it easy for the elderly and children with low immunity. In the move.

In response to this consumption “pain point” of washing machine users, major manufacturers have introduced healthy washing machines with laundry disinfection and sterilization functions, such as Sanyo’s electrolyzed water sterilization, which mainly controls electrolytic tap water through computer programs, thereby decomposing substances to remove dirt. The self-proclaimed sterilization rate can be as high as 99.59%. Some washing machines from Haier, Siemens and Samsung use ozone generators built in to generate ozone to form ozone water to eliminate bacteria and viruses on clothing. Many models of Aucma, Bosch and Midea focus on high temperature cooking to kill bacteria. In addition, there are silver ions of Skyworth wave washing machine and light-moving silver technology of Panasonic washing machine, both of which release silver ions to disinfect clothes.

These sterilization methods are varied, and it sounds inevitable that some consumers will be confused. In this regard, the professional technicians of the local chain fashion electrical washing machine explained that ozone, silver ions and photoactive silver all require a certain medium to react accordingly, and the bactericidal substances they produce must reach a certain level to achieve disinfection. Purpose, while high temperature cooking and sterilization may be easier to understand and accept. “Therefore, when consumers buy washing machines, it is best for the guides to understand these sterilization techniques and make trade-offs according to their own needs,” the professional said.

Second, the washing machine "no-clean" claims that each time the laundry can "bath"

It is understood that the inside and outside of the washing machine is also a place to hide dirt, and its secondary pollution is also a "pain point" of the washing machine. According to Dongguan Suning washing machine after-sales maintenance personnel, due to the working principle and design reasons, the domestic washing machine is generally composed of two layers of inner and outer barrel walls, the inner barrel must bear the cleaning function, but also play a role in the drying, so that it is inevitable in the laundry process The dirt remains in the narrow space of the two-barrel sandwich. After a long period of time, it gradually becomes a region where scale, bacteria and rust gather, and even becomes a breeding ground for bacteria.

How dirty is the long-term use of the washing machine? In the on-site dismantling of the washing machine, the reporter saw that the inner bucket of a washing machine that was used for five or six years was still clean, but there were many black spots on the mezzanine, some black. The plaque even grows into a large piece, giving off an unpleasant taste. This is also an "old problem" that affects the health of users. Manufacturers are also seeking solutions, mainly in the "no-clean" and "self-cleaning" modes.

The former uses the physical method, basically does not need to add any cleaning agent, each time the laundry will automatically wash the washing machine itself; the latter needs to add the washing machine cleaning agent, manually select the cleaning function, and after a period of time The inner bucket needs to be cleaned once.

Of course, even the "no-clean" type of washing machine has different operating principles. Some of them use high-speed rotation to dry the water droplets in the barrel to reduce the possibility of bacterial growth; others use a 70 ° C high temperature hot water removal machine. Various residual stains, including bacteria; others are equipped with antibacterial polymer wisdom balls, which are used to hit the inner and outer barrel walls by high-frequency shots to prevent dirt from adhering, such as Haier’s “clean-free” washing machine. To maintain a long-lasting cleanliness of the inner and outer barrel walls.

“Compared with the manual operation of self-cleaning, the no-clean function is more thorough and convenient for cleaning the inner and outer barrels of the washing machine,” said the person in charge of the relevant department of fashion electronics.

Healthy wash, expensive?

Healthy washing machine is 500~1000 yuan more expensive than traditional ones

The reporter learned from Suning in Dongguan that at present all major brand washing machines have introduced healthy washing machines. Although the terms are different, they are mainly sold in terms of sterilization and no-cleaning. Among them, the proportion of no-clean washing machines is not very large, mainly concentrated in several major brands such as Haier, Siemens and TCL.

Compared with the traditional washing machine, the price of the washing machine with healthy sterilization function is generally higher than 500~1000 yuan.

According to information from fashion appliances, about 80% of the chain-selling washing machines are equipped with self-cleaning or barrel cleaning functions, and the sales volume of washing machines with healthy washing functions is generally increasing.

The relevant industry believes that although the price of the washing machine is higher than that of the traditional washing machine, with the improvement of people's living standards and the improvement of health awareness, "the demand for washing machines will become more and more healthy and smart."

remind

There is no uniform standard for healthy washing

The sterilization effect must be self-identified

In the face of the healthy washing of various so-called technical cards, how should consumers choose, especially what details should be paid attention to?

"At present, washing machines through a variety of ways to achieve healthy washing, indeed some varied." The above-mentioned home appliance chain related seniors believe that the individual health washing technology is currently only a concept, its sterilization function has not been authorized. At the same time, in terms of the healthy sterilization of washing machines, there is currently no uniform mandatory standard, basically the brands are their own. Therefore, he reminded consumers that when purchasing a washing machine with a healthy sterilization function, it is best to ask the on-site guide to inquire carefully, and to understand the principle and effect of sterilization, and to check whether there is any relevant certification from the authority in this regard. .

Suning in Dongguan also believes that the current brands of sterilization washing machines on the market are diverse, and the sterilization techniques used in different washing machines are also different, and the sterilization effect will be different. Therefore, when consumers purchase, it is best to carefully weigh and then according to their own needs and purchasing power, and try to buy in regular stores.

Several ways to open healthy washes

High-temperature washing: It is mainly washed by warm water above 40 °C to remove toxic and harmful substances left on the clothes, and supplemented with high temperature disinfection washing technology of more than 90 degrees Celsius to remove bacteria. This technique is mostly used in drum washing machines, but the time required for heating tends to be too long.

Ozone washing: The ozone generator is used to inject ozone gas into the washing liquid during the washing process, so that the ozone concentration reaches the applicable value of the washing clothes, and the ozone water enhances the decontamination ability of the detergent, and eliminates bacteria, viruses, or purification on the clothes. The amount of detergent on the clothes, but because of its strong oxidizing properties may also cause the clothes to fade or fade, so the washing time should not be too long.

Electrolytic water washing: The electrolysis tap water is mainly controlled by a computer program, and the dirt is removed by decomposing substances. The advantage is that the fabric is not damaged, and the skin of the body can be effectively protected.

Silver ion wash: generally at the bottom of the inner barrel of the washing machine, with a silver ion generator, which can release Ag+ to destroy the activity of bacterial cell enzymes during washing, kill bacteria on clothes and more stubborn fungi, and also can be used for inner and outer barrels and pulsators. It has a sterilization effect to prevent mold growth.

Photodynamic silver washing: Under the action of blue light in the cylinder, silver ions react with water, and hydroxyl radicals are generated to further enhance the sterilization effect of silver ions. The same medium is required as the silver ion wash, and it is necessary to achieve a certain level of sterilization effect. Of course, as the use time gets longer, the effect may gradually weaken.
