Guide to the purchase and maintenance of drinking fountains
A few days ago, in order to promote "fearless drinking fountains", an enterprise began to create a strange theory that the mainstream drinking fountains on the market were "toxic". Although this statement is exemplified by people in related industries as unfounded, it has also attracted the attention of consumers.
At present, there are two misunderstandings about household drinking fountains: first, I don't know how to buy them. Some people think that low-tech products can be cheaper, and some consumers think that the more expensive the better, they will know that they are not suitable for themselves after buying them; The second is that I don't know the common sense of drinking machine cleaning. As a result, pure water has become "impure" for a long time, affecting the health of yourself and your family. Drinking water is healthy, first of all, we must choose a suitable water processor, and we also need to have relevant cleaning knowledge.

Choose a water dispenser that suits you.
To buy a drinking fountain, you must first understand its classification, so that you can choose one that suits you.
1
Classification by appearance
Can be divided into desktop and vertical (or floor-standing) two categories. Desktop drinking fountains are generally not equipped with disinfection cabinets or lockers, so they are smaller and more convenient to move. The upper part of the vertical water dispenser is a water dispenser, and the lower part is a disinfection cabinet or locker, which can disinfect tea sets or store fresh food. Some models are also equipped with a small freezer for freezing drinks.

Classification by drinking water temperature
It can be divided into three types: warm type, cold type and three-temperature type. The warm water machine is equipped with normal temperature/hot water faucet, which supplies normal temperature water /88-96℃ hot water respectively; Cold and hot water dispensers are also called ice and hot water dispensers because of the low temperature of cold water. This model is equipped with cold/hot water taps, which supply 5 ~ 12℃ cold water /88 ~ 96℃ hot water respectively. The three-temperature water dispenser integrates the functions of the above two models and is equipped with three faucets to supply normal temperature water, cold water and hot water respectively.
three
Classification by refrigeration mode
It can be divided into electronic refrigeration type and compressor refrigeration type, and each type can be divided into desktop and vertical drinking fountains. The electronic refrigeration water dispenser uses semiconductor components for refrigeration, also known as semiconductor refrigeration water dispenser, which has the characteristics of low power consumption, low operating noise, no pollution, automatic control and low price. The disadvantage is that the cooling speed is slow and the supply of cold water is small, which is suitable for families and units with little drinking water. The refrigeration principle of compressor refrigeration water dispenser is the same as that of refrigerator, but the difference is that the evaporator is wrapped on the wall of stainless steel water tank to absorb heat to cool water. The refrigerating capacity is about 3L, and the refrigerating power is between 75- 1 10W. It has the characteristics of high reliability, high refrigeration efficiency, fast refrigeration speed and large cold water supply. The refrigeration performance is obviously better than that of electronic refrigeration water dispenser, but the price is higher, which is suitable for families who drink a lot of water.

Classification by water source
It can be divided into bottled water and tap water. The water dispenser using bottled water is 18.9L(5 gallons) or 1 1.3L water source, which is supplied by the water supply center. In addition to the above functions, the drinking machine using tap water is also equipped with a reverse osmosis (RO) water purifier or filter cartridge, which can automatically filter tap water, and can be used by turning on the power supply after filling water. It is the product with the most functions in the water dispenser, which is characterized by no need to change bottles, low maintenance cost and convenient use. However, this kind of drinking machine needs to replace the filter element and filter membrane regularly, which is expensive.
five
Classification by control mode
It is divided into three types: ordinary control type, intelligent induction type and microcomputer control type. The common control type water dispenser has automatic constant temperature control of heating and cooling, and is the most used model by users at present. The intelligent inductive drinking fountain uses human infrared sensing, the distance is within 7 meters, and the viewing angle is 120. Automatic switch when people are away, characterized by safe use, automatic switch and energy saving. Controlled by microcomputer and single chip microcomputer, automatic temperature control of heating and refrigeration, with functions of water temperature display, multi-stage temperature setting, accurate temperature control, power off at regular intervals, and various sound and light prompts.

Bacteriostatic water dispenser
This is a drinking machine developed in recent years. In addition to the functions of ordinary drinking fountains, drinking fountains are plastic parts that come into contact with water or are exposed to the air, such as water guide columns, water tanks, faucets, etc. And silicone rubber connecting water pipes and seals are all treated by adding "RS antibacterial agent". Through slow release, it can inhibit the breeding and reproduction of many harmful bacteria such as Escherichia coli and Staphylococcus aureus, and maintain antibacterial effect for a long time.
Selection and purchase
Four steps of quality inspection
It's best to buy a water dispenser in a reputable shopping mall, so that if there are quality problems, you can recover them. To put it simply, buying a water dispenser only requires the following four steps:
Look at the brand. The wading parts of big brand water dispensers are all made of nationally certified food-grade materials, which will not cause heavy metal pollution. Using non-food grade materials (such as industrial plastics), contact with water may release harmful substances such as heavy metals.
See the certification. Drinking fountains need to pass two certifications: one is 3C certification, which mainly ensures the electrical safety performance of products, and the other is hygiene license, which is used to ensure the hygiene performance.
Look at the appearance. The surface of plastic parts of drinking fountains should be smooth and uniform, with the same color. The plastics with rough, dim and yellow colors are generally recycled materials, which are easy to change color and cause pollution.
Look at the parameters. The parameters on the product nameplate are clear at a glance, and the indicators such as power consumption and noise directly reflect the performance of the product. Generally speaking, high power consumption is high and noise is high.
wash
Daily disinfection is essential.
At room temperature, the colony index of the water in the drinking fountain is 0 on the first day, 10, and it will rise to 8000 after 00 days. Judging from the structure of the drinking machine, there are two water tanks, one is hot water tank and the other is cold water tank, which play the role of precipitating impurities in water. Usually, after drinking a bucket of water, people only change it into another bucket, ignoring about 1000 ml of water in the inner container of the barrel water machine. Over time, the internal bladder has become a hotbed of bacteria, and bacteria continue to multiply, which may cause more than 50 diseases such as digestion and urinary system. Some people often suffer from gastrointestinal diseases but can't find the reason. In fact, the "killer" of the water dispenser is also very suspicious. Therefore, once the drinking fountain is polluted, it is useless to purify pure water. Only by forming the habit of cleaning the drinking fountain regularly can the hygiene and safety of drinking water be guaranteed.
The cleaning and disinfection of drinking fountains is generally once every three months in summer and once every six months in winter/kloc-0. Bottled water that has been opened for more than 15 days can no longer be drunk. Here are eight steps to clean the water dispenser in an orderly way-
Cut off the power supply of the drinking machine;
Insert the water bottle vertically downward into the intelligent seat at the upper part of the machine, turn on the red hot water faucet and the blue cold water faucet until water is discharged, then turn off the faucet, then hold the bottle body with both hands and take out the water bottle upward;
Clean the outside of the drinking fountain and intelligent seat;
Pour 600ml of special cleaning disinfectant (disinfectant should be prepared according to the dosage specified in the product) into the water storage tank, or mix a piece of disinfectant with 5 ~ 6 liters of purified water to prepare disinfectant;
After continuous soaking and disinfection for 20 minutes, turn on the red and green faucets until the disinfectant is exhausted;
Unscrew the drain valve on the back or bottom of the machine to discharge the disinfectant in the water dispenser;
Rinse repeatedly with boiling water or purified water for several times until the tap water is tasteless;
Tighten the drain valve, and the disinfection and sterilization operation procedure is completed.
