Step 1: Unplug the power supply, remove the bucket. Remove all the remaining water in the water dispenser cavity. Since the remaining water in the water dispenser drain pipe is the key to the secondary pollution of the water dispenser, open the drain pipe behind the water dispenser to drain the remaining water inside, and then open all the drinking water switches to release the remaining water in the water dispenser cavity.
The second step: use clean tweezers to hold a disinfectant alcohol cotton ball, carefully scrub the water dispenser "smart seat". Usually these parts of the water dispenser are in direct contact with the air and can easily accumulate bacteria. Scrubbing with sterilized alcohol cotton can remove the dirt on it, but also prepare for the next step of disinfection.
Step 3: The general household water dispenser cavity has a capacity of about 2,000 milliliters, dissolve 300 milliliters of disinfectant in about 2,000 milliliters of water, then fill the entire cavity, and open the dispenser, including the drain pipe and the drinking switch to discharge the disinfectant solution after 10-15 minutes.
The fourth step: 7000-8000 milliliters of water will be 7000-8000 milliliters of water continuously rinsing the entire cavity of the water dispenser and then open all the switches to drain the rinsing liquid.
Step 5: Scrub the back wall of the water dispenser at the faucet switches with sterilized alcohol cotton.
Step 6: Since the water dispenser has just been disinfected, there may still be a trace of disinfectant residue, so you can't drink it right away. First you should pick up a cup of water to smell whether there is the smell of disinfectant, if so, you need to keep draining the water until the water can not smell before you can drink with confidence.
Drinking fountains, if not disinfected or not cleaned for a long time, will lead to the machine's water storage gallon deposits of dirt, breeding a large number of bacteria, and even breeding red worms, a serious danger to people's health. Water dispenser inside the cold, hot two water gallons, these two water gallons in addition to play a role in the production of hot and cold water, but also the role of precipitation of impurities in the water. When we keep replacing the barrels of water but ignored the water dispenser liner is still nearly 1000 milliliters of water, over time, these water naturally become a breeding ground for bacteria, breeding bacteria hidden in the liner of the water dispenser, and these disease-causing bacteria along with the drinking water into the human body will trigger digestive, urinary, neurological, and many other diseases.
The neck of the barrel: The neck of the barrel is the closest contact with the water dispenser's "smart seat". If the neck part of the barrel water bottle sealing is poor, disinfection is not strict, and even the use of poor-quality bottle cap, in the transport process, the bottle cap is easy to disengage, so that the drinking water is subjected to secondary pollution.
