Many homes have water dispensers, is the water from the water dispenser safe?

In fact, if it is a water dispenser produced by a regular manufacturer, and the use is standardized, there is actually no problem, but if it is an illegally produced water dispenser, and the use is not standardized, there will be the following problems:

The first problem is limescale. Water dispensers are prone to limescale, especially in water hardness.

Higher areas. Most of the white precipitates that appear are carbonates.

Kind. In fact, these salts exist in a very stable form of compounds, and there is no evidence that they are harmful to humans. However, the presence of these substances affects the efficiency of heat exchange, and when the fouling is serious, it will bring safety hazards.

Therefore, the water dispenser should be descaled in time.

The second problem is aged water. Water dispensers are prone to limescale, especially in areas with high water hardness. Most of the white precipitates present are carbonates.

In fact, these salts exist in a very stable form of compounds, and there is no evidence that they are harmful to humans. However, the presence of these substances affects the efficiency of heat exchange, and when the fouling is serious, it will bring safety hazards. Therefore, it can be seen from here that the water dispenser must be descaled in time.

The third problem is nitrite.

problems. Since the water contains nitrate nitrogen, when the microbial contamination of the water dispenser is severe, it will promote the conversion of nitrate nitrogen to nitrite nitrogen. The WHO Drinking Water Directive stipulates that when this indicator exceeds 3 mg L in a short period of time, the infant will develop methemoglobinosis.

From the current research, there is not enough evidence to suggest that nitrite is associated with cancer.

There is a direct relationship.

The fourth problem is that the material of the heated bile causes the precipitation of harmful substances. In fact, for this problem, in fact, the main problem is inferior and shoddy products, and there is no such problem in general regular manufacturers. Therefore, when buying a water dispenser, be sure to use products made by regular manufacturers.

All in all, for water dispensers bought from regular channels, if they are properly maintained, there is actually no big problem. However, if it is an inferior product, it will create a lot of problems.

The water inlet, inner wall of the water storage tank and cold water pipes of the water dispenser are very susceptible to the growth of bacteria due to the appropriate temperature, even when using qualified bottled water. If you do not pay attention to cleaning, it will cause diseases of the human digestive system and urinary system.

The water from the water dispenser is safe, but don't leave it for too long, some bacteria in the air will breed in the water, and the water will be contaminated after a long time.

I think the water in the water dispenser is relatively safe, after all, this kind of enterprise they have relevant quality inspection should have a little guarantee on the physical aspect.

Safe. Direct drinking water in the community can be drunk with confidence, but the direct drinking water vending machine is contracted to individuals, and the maintenance of the equipment is difficult to guarantee. Like household water purifiers, the water purification effect of community water purification equipment also depends on the filter element.

Direct drinking water in the community can generally be drunk with confidence, but the direct drinking water vending machine is contracted to individuals, and the maintenance of the equipment is difficult to guarantee. Like household water purifiers, the water purification effect of community water purification equipment also depends on the filter element, however, the filter element they use is larger than that of household water purifiers, and the service life is longer and longer. At present, most of the direct drinking water vending machines in the community adopt the mode of individual contracting, and the contractor will maintain them.

The condition of the machine and the quality of the water depend not only on the contractor's sense of responsibility, but also on the water treatment technology used in the machine. Even if the manufacturer guarantees the technical quality of the filtered water, if it continues to adopt the individual contracting model, it will still cause negligence in later maintenance and water quality supervision.

Personally, I think the household water dispenser is still very easy to use. With the development of modern society, people's living standards continue to improve, clothing, food, housing and transportation have been greatly improved, now, water dispensers are a household appliance I believe many people have used it! Although some families no longer use them, there are still many families who insist on using water dispensers, and even many school dormitories use water dispensers.

So let's talk about whether the water dispenser is good or not!

First of all, let's take a brief look at the working principle of the water dispenser, when using the water dispenser, press the heating switch, and the power supply will supply power to the "keep warm" indicator for power-on indication. At the same time, the power supply is divided into two circuits: one way forms a heating circuit to make the electric heating pipe electrically heated; The other circuit provides the voltage to the "heating" indicator for the heating indication.

When the water in the hot water tank heats up to the set temperature, the thermostat contacts are disconnected, the power supply to the heating and heating indication circuit is cut off, the "heating" indicator light is off, and the electric heating pipe stops heating. Purified or mineral water equipped with a water dispenser is sterilized and ready to drink, and in general, the water in the water dispenser cannot be boiled to 100 degrees. For some better quality water dispensers, it can be heated to 100 degrees and cooled, and the temperature can be adjusted arbitrarily, which is very convenient.

The second is the advantages of the water dispenser, first, the direct water dispenser adopts heat exchange technology. Not only does it purify the water, but it also provides hot water, and it is also more energy-efficient compared to regular boiling water heaters. Second, the purification function of the drinking machine is very strong.

The direct drinking water dispenser uses ultrafiltration filtration and activated carbon filtration technology to remove all bacteria and toxins when purifying the water, fully complying with hygienic water standards. Thirdly, the water purified by the water dispenser is very clean and hygienic, and it is safe to drink when drinking.

In general, the household water dispenser is still very easy to use, not only convenient and affordable, but also energy-saving and environmentally friendly, in line with the development of the new era of the product, the above views are only views.

Personally, I don't think it's easy to use because it's not easy to change the bucket every time, and it also needs to be cleaned regularly, which is very troublesome to use.

The household water dispenser is very good, especially easy to use, very convenient and affordable, and very cheap.

Personally, I think the household water dispenser is very easy to use, because you only need to press the switch to connect the water.

As the state pays more and more attention to the quality of life of residents, nowadays, many communities have direct drinking water, which is cheaper and healthier than simple tap water. The follow-up found that these direct drinking water can buy about 5L of water for about 5 liters for one dollar.

But there are still many people who keep an eye on the purification process when they can see the place where the water is connected, especially the obvious water dispenser. First tap water, then seven or eight procedures, and finally filtration before it can be sold, many people believe that it is safe.

Compared with buying water dispensers and wearing filters online, it is convenient and cheap, and it can be clearly seen that there is no scale after boiling such water, but is it really impeccable behind this? Are there any safety hazards?

Through the detection of relevant departments, it is found that there are indeed certain defects in the direct drinking water in the community, and the direct drinking water machine in some communities, because the state has not yet had the corresponding mandatory management rules, if it is exploited by unscrupulous traders, the safety of the water is difficult to guarantee.

However, after all, it involves the safety of drinking water, so the relevant urban areas will conduct random inspections of these water supply equipment every year, and formal places need to meet the national health permit and water quality standards.

In addition, the direct drinking water in some communities is also known as "healthy and good water", which further increases the nutrients in the water by improving the mineral composition of the water. The following features are included in the United Nations World Health Organization's drinking standards for healthy water:

It does not contain any toxic, harmful and odorous substances; The pH value is weakly alkaline; Rich in trace elements and minerals; The water molecule is small; Strong permeability. No one can guarantee that you can really drink such water, so you can focus on whether there is a national health license when receiving water, or consult the specific situation of the business, so that it can be safer to drink.

In addition, for drinking water without a label, for everyone's safety, you may wish to boil it before drinking, through the high temperature can destroy bacteria, drink no abnormality, and avoid food poisoning to the greatest extent. For tap water in the home, although the tap water standard in most areas, that is, the "Sanitary Standard for Drinking Water", stipulates 106 water quality indicators, drinking it in moderation will not cause physical discomfort. However, for safety reasons, it is recommended that everyone boil it before drinking.

As for residual chlorine, which some people are worried about, it is to prevent people from growing bacteria during transportation, and the country has a limit on residual chlorine. According to the World Health Organization, it should not exceed 5 mg per liter of water. Under normal circumstances, the residual chlorine in tap water is within a healthy range, so you don't have to worry about this, just drink it with confidence.

Whether or not you choose to buy a water dispenser at home is okay. The demand for water dispensers should be determined according to their own needs and the pursuit of life, if you choose to install a water dispenser, try to choose a water dispenser that suits you, and you need to clean it. If you feel that you don't need to install a water dispenser at home, you can choose direct drinking water instead.

Types of Water Dispensers:

Warm water dispenser. The hot water dispenser mainly provides two types of direct drinking water, room temperature and hot water, and does not have the effect of refrigeration. The price is cheap, but the functions are relatively simple and not practical enough.

Ice hot water dispenser. It can provide two kinds of cold direct drinking water and hot direct drinking water, but it cannot provide normal temperature drinking water, and there is only one power switch in the fuselage, which cannot control the refrigeration and power off, which is easy to cause a waste of electrical resources.

Ice warm water dispenser. It can provide drinking water at three temperatures: cold water, warm water and hot water, among which the two functions of refrigeration and heating have independent switches, when the refrigeration switch is turned on, the cold water outlet will provide cold water, and when the refrigeration switch is closed, the cold water outlet will provide room temperature water. This kind of water dispenser has a relatively comprehensive function and can basically meet all the needs of life.

Water Dispenser Cleaning Matters:

1. The water dispenser should be thoroughly cleaned at least once every 2 months, and when the temperature is high in summer, it should be thoroughly cleaned once a month to avoid the breeding of bacteria.

2. When cleaning the inside of the water dispenser, you can use lemon to assist in cleaning. After cutting the lemon in half, squeeze out the juice from the lemon and mix it into a lemon solution according to the ratio of one lemon to 250ml of water.

After the water dispenser is powered off, release all the water inside, then pour the blended lemon solution into the water dispenser, then turn on the power to boil and turn off the power, and pour out the cooled lemonade and rinse it a few times.

When the water dispenser is not installed, a water purifier can be installed next to the faucet to sterilize and disinfect the direct drinking water and avoid the bacteria in the direct drinking water from causing harm to the body.

There are three main aspects of water dispenser safety:

First, the safe power control part:

Try to buy a water dispenser with a fixed time function, this machine has two advantages:

a.Power saving: The water dispenser has been plugged in, and the constant temperature guarantee nuclear temperature work is very power-consuming. For a fixed period of time, the machine automatically cuts off the power during the period of non-use and automatically starts the work better during the time period when it needs to be used.

b.Safety: The electronic control part of the machine does not need to be powered on all the time, and there is no need to carry out the aging or life test of the machine!

In addition, when you use the time period, you will find a higher probability even if the machine fails, for example, spontaneous combustion caused by the internal control circuitry of the machine (which is very unlikely), the machine will not keep warm, and the relative failure rate will occur when the chance is not very small.

c.The service life of the machine's heating parts is extended.

If the water dispenser does not have a working function within a fixed time, you can buy a socket on the market with a fixed time setting function to achieve the purpose of digging early in the morning, in addition, the most important point is that the household main power switch and the main shunt switch have the leakage protection function of the first brand products.

Second, the safety of the water treatment system.

1.Provide water with bottled water:

a.We need to clean the machine lining or related parts regularly;

b.Buy a brand of water dispenser, relatively speaking, the internal components are slightly better or self-comfort should be better;

c.The long-term bottled water brand must be a well-known brand, and do not use local brands and barrels.

dPay attention to the use habits, try to use small barrels of water or bagged water, the water should be used up within two or three days, do not use a bucket of water for a week.

2.Use a water purifier to filter the water supply:

a.We need to clean the machine lining or related parts regularly;

b.Buy a brand of water dispenser, relatively speaking, the internal components are slightly better or self-comfort should be better;

c.The filter should be replaced regularly, do not consider the cost of use can not be changed, the filtered water is not as good as tap water;

d.It is best to use membrane filtration, especially with reverse osmosis membranes;

Third, brand effect:

Basically, the material selection of the brand part is more standardized, or self-soothing (don't be superstitious about the brand**, there are too many insiders, and every link is prone to problems).
