Is it good to boil water from a water dispenser repeatedly?

Bad not only destroys minerals but also produces some harmful substances.

Bad is a certainty.

First of all, the water boiled by the water dispenser is not boiling water at 100 degrees Celsius, and it can be more than 80 degrees, so it cannot achieve the effect of complete disinfection and sterilization (besides, we can't be sure whether the water from the water dispenser is pure water).

Secondly, unless the water dispenser is often cleaned with a special cleaning agent, the dirt and dirt in it are very serious, and we once cleaned the water dispenser in our office, and then we began to boil water and drink it ourselves. (It is also time-consuming, laborious and water-intensive to wash once).

Finally, the water that has been boiled repeatedly is called a thousand boiling water. About this, you can find it in the encyclopedia.

Not good, repeated boiling of water produces a toxic substance. Of course, the chance of producing this substance is very low.

There are a lot of minerals in the water (I mean tap water), and repeatedly boiling it is like boiling porridge, and the concentration of minerals in it will increase, which is definitely not good. It's okay to burn it when you use it, but it costs electricity.

That's a good habit. Recent studies have shown that boiling water repeatedly does not cause much harm to the human body.

It is not good to boil water repeatedly, such water is easy to cause cancer, it is recommended not to boil it repeatedly...

Not good, repeated boiling will lead to hard water quality, easy to induce stones, and long-term drinking of pure water is not good, will lead to the lack of trace elements, so it is best to insist on drinking and cooking, and tap water, pure water alternately. Hope it helps the landlord, thank you :)

It should be bad! It's not convenient to always switch on and off. My house is boiled and poured into a thermos. This avoids repeated burning and does not require constant switching on and off. Hope it helps!

It's not good, it's better to drink as much as you want, and how much you pack! Don't boil it over and over again!

It's not good, no matter what kind of water is boiled repeatedly, it's not good.

It's good, kill the bacteria several times.

OK.

The hot water of the water dispenser, as long as it is lower than the set temperature is generally 70-80 degrees, he will automatically boil the water, and his water will be boiled to 100 degrees, and then it will automatically turn off the power and cycle repeatedly, because he has not been boiling the water, so it will not produce nitrite.

The water in the water dispenser does not reach 100°C, and the water is generally about 80°C when it is insulated, so the scale produced is less than that of boiling water (scale, that is, nitrite). It is recommended that you do not turn on the "heat" for a long time when you do not usually drink hot water.

Choice of features. It is quite important to consider the purchase of water dispensers from the perspective of functional use. If you don't like to use a water dispenser to adjust cold drinks, daily only for making tea and coffee, buy a warm water dispenser, both practical and economical, if there are more young people, plus located in the southern tropics, the summer use rate is higher, and like cold drinks, you should buy hot and cold water dispensers.

In addition, there is also an ice and warm three-purpose machine, which can be selected according to your needs.

Yes. Because after the water dispenser turns on the "heat" switch, it will start to boil water until the water temperature reaches its specified maximum temperature (generally seventy or eighty degrees), and it will automatically turn to the "keep warm" switch. When you pour out some of the boiling water, the heater is refilled with cold water, so that the cold water is mixed with the previous hot water, and according to the principle of "heat transfer" in physics, the total water temperature drops.

Therefore, at this time, the water dispenser will automatically "heat" again to the highest temperature, and then turn to the "keep warm" state. As a result, the hot water from the water dispenser will boil repeatedly.

Hello, I am Mr. Zhixing, I am giving you the best answers and suggestions according to your questions, you just need to wait patiently for a while, I will reply to you within five minutes, thank you very much.

Hello, the drinking machine will burn repeatedly. Because after the water dispenser turns on the "heat" switch, it will start to boil water until the water temperature reaches its specified maximum temperature (generally seventy or eighty degrees), and it will automatically turn to the "keep warm" switch. When you pour out some of the boiling water, the heater is refilled with cold water, so that the cold water is mixed with the previous hot water, and according to the principle of "heat transfer" in physics, the total water temperature drops.

Therefore, at this time, the water dispenser will automatically "heat" again to the highest temperature, and then turn to the "keep warm" state. As a result, the hot water from the water dispenser will boil repeatedly. I hope mine is helpful to you.

Hope mine is helpful to you. Please also give a thumbs up, thank you in advance, and I wish you a happy life.

It's not very good.

But the water in the water dispenser is different from boiling the water yourself.

Repeated boiling of self-boiled water, commonly known as "thousand boiling water", repeated boiling of water will turn the nitrate in the water into nitrite, and nitrite will make the hemoglobin in the human body into nitrite hemoglobin, which will make the red blood cells lose the function of carrying oxygen.

However, it takes 100 degrees Celsius for nitrate in water to convert into nitrite, and the water in the water dispenser generally stops heating when it is heated to 85 degrees Celsius, so although the repeated heating of the water dispenser is not very good, it is not a big problem, as long as you pay attention to the hygiene of the water dispenser.

The water dispenser is not good to boil water repeatedly, mainly for the following reasons:

1. If the water in the water heater is heated repeatedly for more than ten hours or several days (some people call it "thousand boiling water.")

If not replaced, this water may contain high health hazards, such as harmful substances dissolved in heating elements and containers, and some trace harmful substances contained in raw water will also accumulate and increase.

2. After the water is boiled many times, the dissolved oxygen in the water runs out, and drinking oxygen-deficient water is not good for health.

3. Due to boiling for too long, the scale will dissolve into the water, and the concentration of heavy metals such as calcium and magnesium in the water will increase, making the water hard, which is not good for health. Hard water.

Calcium carbonate is formed after boiling with a medium concentration of calcium and magnesium ions.

Magnesium carbonate, magnesium hydroxide.

and other insoluble substances precipitate down to form scale.

It's okay, you can drink it the same, but it's best not to boil the water repeatedly.

Is it good to come to your water dispenser and boil water repeatedly? Because of the water dispenser, he also gets a certain temperature to boil well, so the water is going to go down to the temperature, and it burns repeatedly.

The hot water of the water dispenser is boiled repeatedly. The hot water of the water dispenser, as long as it is lower than the set temperature, generally 70-80 degrees, will automatically boil the water, and the water will boil to 100 degrees, and then it will automatically turn off the power and cycle repeatedly. However, even if the water in the water dispenser is boiled repeatedly, it will be boiled three or four times at most, and there are many people who use it, and there are people who keep getting water to drink, and the hot water in it will not be stored for a long time, so it will be released.

There is also a kind of water dispenser that is generally connected to the hot water below, and the cold water begins to flow into the storage tank below, so there will be the sound of "goo-goo-goo" pouring water down, which is the situation of adding new water while putting hot water.

Use and maintenance:

1. The handling machine should be handled gently, and when the water dispenser refrigerated by the compressor should be moved as much as possible, if it is to be tilted, its inclination shall not be greater than 45 degrees, and it should be stationary for a period of time after handling before it can work.

2. When using the water dispenser for the first time, clean the containers and pipelines of the water dispenser with clean water, then unscrew the drain valve, and tighten the drain valve after draining the remaining water in the machine. After adding a large bottle of water, turn on the hot water faucet, and then plug in the power supply and turn on the heating switch after the water flows out, so as to avoid dry boiling and prolong the life of the machine.

3. If the water dispenser is out of service for a long time, please turn off the switch of the machine and unplug the power plug, then unscrew the drain valve, drain the remaining water in the machine, and then tighten the drain valve (please pay attention to hot water scalding during the draining process).

4. It is best to disconnect the power supply when not in use at night, which can save energy and ensure safety when no one is in use.

5. During the use of the machine, it is recommended to clean and disinfect it once in about 3 months according to the specific situation, and use it for one year.

6. The water dispenser should be placed in a ventilated place to prevent moisture, avoid direct sunlight, and stay away from heating. The water dispenser should be about 15 cm away from the wall and should not be placed near valuable furniture and other household appliances to avoid splashing water and damaging the items. The water dispenser must be placed smoothly to prevent the machine from making noise.

7. It is forbidden to use organic solvents such as gasoline to clean the surface of the machine.

8. If the power cord is found to be damaged, the water dispenser must be replaced with a special soft cord or contact the dealer. The machine must use a socket with a grounding device and a leakage protector to prevent the enclosure from becoming electrified.

9. Children should not play next to the water dispenser, and if necessary, replace the hot water faucet with a safety faucet to prevent children from being burned.

10. Do not put the metal rod into the back plate ventilation window, so as not to damage the fan or cause electric shock; Do not cover the fan ventilation window to avoid damage to the semiconductor refrigeration components due to poor exhaust and poor heat dissipation.

11. When the water dispenser refrigerated by compressor is disconnected, it must be started again after 3-5 minutes to prolong the life of the machine.

12. When pressing the faucet to receive water, do not use too much force, so as not to fall out or damage the rotating part of the hand.

The water dispenser can drink water that has been boiled repeatedly. Repeatedly boiled water is called boiling water, and there is no discomfort after drinking it. And the traditional water dispenser will not boil the water to boiling, it can only be heated to about 90, so there will be no harm and you can drink it with confidence.

Water dispenser. It is a device that warms or cools bottled purified water (or mineral water) and makes it convenient for people to drink. Bottled water is placed above the machine, which is used in conjunction with bottled water.

Water dispensers are divided into three types: warm, ice hot, and ice warm, and ice heaters are divided into semiconductor refrigerated water dispensers and compressor refrigerated water dispensers. Bottled water is placed above the machine, which is used in conjunction with bottled water. Bottled water dispenser appeared before the middle of the 20th century, this water dispenser is designed as a special connector on the top of the fuselage to place the bucket, the most ** foreign water dispenser puts the bottled water in the lower part of the machine, sucked in by the suction pump, this way is safer and more hygienic than the conventional water dispenser, due to the different water dispensers, there are many kinds of barrel specifications.

If you don't like to use a water dispenser to adjust cold drinks, daily only for making tea and coffee, buy a warm water dispenser, both practical and economical, if there are more young people, plus located in the southern tropics, the summer use rate is higher, and like cold drinks, you should buy hot and cold water dispensers. In addition, there is also an ice and warm three-purpose machine, which can be selected according to your needs.

Repeatedly boiling hot water is harmful to the body when drunk for a long time. The boiling point of the water dispenser is generally about 80 degrees, and it is not recommended to drink it if it is heated frequently, and it is recommended to drink boiled boiled water.

1. If the water of the water dispenser is not replaced, it will be heated repeatedly, and the water may contain substances that affect human health, such as harmful substances dissolved from the heating element. When harmful substances accumulate in the human body to a certain extent, people will get sick.

2. The water is boiled repeatedly, and the dissolved oxygen in the water is gone, and drinking such water is not conducive to human health.

3. If the water is boiled repeatedly, the water quality will become hard, and the hard water contains too much calcium celery with magnesium ions, and people may have gastrointestinal disorders after ingestion, and in addition, the scale dissolves into the water, which is not conducive to human health.

Avoid the method of boiling water repeatedly

1. When purchasing, you can choose an antibacterial water dispenser, because this kind of water dispenser is heated in layers, and the amount of water heated each time is not much, and it can be drunk at one time, which is more conducive to human health.

2. Some water dispensers are equipped with electronic energy savers, which can heat water according to user needs and cut off power according to the usage rate, so as to avoid repeated boiling of water to form thousands of boiling water.

How to use the water dispenser correctly?

Water dispensers have become an inseparable source of drinking water in our lives. However, improper use of water dispensers will cause safety accidents and affect our health. So how to use the water dispenser correctly?

1. Place it correctly.

The water dispenser should not be placed on combustibles, too close to flammables, and not placed in a room with flammable, explosive and corrosive gases for a long time.

2. Do not use the power supply when the first child is closed.

When using the water dispenser, be careful not to plug the power plug into the temporary power strip and use the temporary power supply to avoid damage to the water dispenser.

3. Prevent dry burning.

When you run out of water in the bucket, remember to unplug it, and never dry boil it in a waterless state, as it can easily cause a fire. If there is spare water, replace it in time.

4. Avoid turning on for a long time.

If there is a problem with the internal components, continuous heating will cause a fire when it reaches a certain temperature. Therefore, when there is no one at home, do not turn on the water dispenser, and unplug the water dispenser every time you use it.

The water in the water dispenser is repeatedly boiled, and a nitrite substance will be formed, and if the content is too much, it will cause certain harm to the human body, but the water in the water dispenser is repeatedly boiled about 20 times, and the nitrite content is still relatively low, which can not cause harm to the human body at all, so there is no great harm to the repeated burning of water.

There is not much harm in the repeated boiling of water in the water dispenser, after the water in the water dispenser is boiled many times, the nitrate in the water will be decomposed to form nitrite, nitrite is a toxic substance, the water quality is repeatedly boiled about 20 times, nitrite is about 3% in the daily life, and its content can not cause harm to the human body at all, so there is no great harm to the repeated burning of water.

If the water stored in the water dispenser is too long, the water quality will not be fresh, and there are problems such as bacterial pollution, so the water of the water dispenser is best to drink it in a short time, especially in summer, when the temperature exceeds 30, the bacterial reproduction will be accelerated, the water quality is easy to be polluted, and the human body will drink spoiled water, and diarrhea will occur.

Raw water in nature has not been disinfected, contains harmful microorganisms, is not directly drinkable, let alone mixed with hot water to drink, harmful to the human body, if the water source in the water dispenser is hygienic and safe, then even cold water can be directly drunk.
