We usually have automatic water dispensers at home or in the company. We always drink at ease, but we don't know how long the open bucket can hold water? Let's follow Sihai net to learn more
How long can the water in the water dispenser be put in the bucket? Generally, the shelf life is 3 months, but this is in the case of unopened. If it is opened, it can be drunk for up to 15 days
It is understood that if Kaifeng bottled water is kept for more than half a month, although the taste has not changed, the bacteria have exceeded the standard
Bottled water is highly purified in production and delivery. Generally, the quality of bottled water certified by QS can pass the standard. However, if the bottled water is opened and sealed for more than 15 days, the rapid growth of bacteria in the water will easily cause diarrhea
Note: prevent secondary pollution
Can the repeatedly heated water in the water dispenser be drunk? It is better not to drink the repeatedly heated water in the water dispenser, because:
1. The mineral elements in the water may be reduced or lost if the water in the water dispenser is repeatedly heated and stored in the tank for a long time
2. The water dispenser is in heating state for a long time and does not close after work. Toxic substances such as heavy metals and arsenide will be produced in the water. Moreover, after repeated heating, the activity of the water will be reduced, and the content of ferrous, aluminum and ammonium sulfite will be significantly increased. Long term drinking will harm the health of the stomach and intestines
3. If the office cleaner is lazy and does not clean the water dispenser in time, it is likely to cause a large number of pathogenic microorganisms, which are attached to the inner wall of the water dispenser. After heating, the microorganisms will enter your digestive tract along with the drinking process, causing intestinal diseases
How can office workers drink water healthily? 1. They don't have to drink office bottled water. They can bring some fruit or go to the nearby supermarket to buy some bottled mineral water
2. If you think it's not cost-effective to buy mineral water, try to drink the water you cooked at home to balance the physical harm caused by drinking purified water often
3. On weekends or holidays, when no one uses the water dispenser for a long time, it is recommended to turn off the power supply and avoid repeated heating to produce harmful substances in the water
Steps for cleaning the water dispenser: 1. Unplug the power plug, take down the bucket, open the drain pipe at the back of the water dispenser (usually the knob made of white plastic material) to drain the residual water, and then turn on the hot and cold water switch to drain the water
In this process, it is worth noting that the blowdown pipe of the vertical water dispenser is generally located at the back of the machine, while the desktop water dispenser is located at the bottom of the machine, which can be seen only when the desktop water dispenser is lifted up
2. Turn it anticlockwise, take down the smart seat (that is, the part inside the water dispenser that touches the spring bucket), and scrub the inner and outer sides of the water dispenser's tank and cover carefully with alcohol cotton to prepare for the next step of disinfection
3. According to the instructions of decontamination effervescent tablets or disinfectants, configure the disinfectant water (both decontamination effervescent tablets and special disinfectants are sold in supermarkets, and the price is not expensive), introduce it into the water dispenser, fill the whole cavity with the disinfectant water, and leave it for 10-15 minutes
This link is worth noting: if there is no decontamination effervescent tablets, disinfectants or disinfectant water, you can boil a pot of hot water, the hot water into the water dispenser, also 10-15 minutes
The purpose of this method is to use high temperature to eliminate the bacteria
4. Turn on all the switches of the water dispenser, including the drain pipe and water switch, and drain the disinfectant or boiled water
