In the blink of an eye, I have been in the home appliance industry for 12 years, and in 12 years I have been full of all kinds of heartache, but I have seen that many users do not know enough about household appliances, there are certain improper methods in use and maintenance, and the heart is even more full of miscellaneous bottles. The day before yesterday I sent a "cleaning water heater risky I quoted 150 others 80 on the cleaning of the result let me clean up the mess", there is a photo on the top is like this, causing a lot of controversy among netizens.
The line had been pressed by the flange
Many netizens think that cleaning the electric water heater does not need to disassemble the flange plate at all, how can the wire be pressed inside? It's clear that I'm just cheating traffic. In fact, the regular cleaning of electric water heaters, it is definitely necessary to dismantle the flange, remove the heating pipe to clean, otherwise, all home appliances cleaning is a hooligan.
With the continuous improvement of people's living standards, home appliance cleaning has become a new industry, and there are billions of transactions in this industry every year. Therefore, a chain of generation has been generated, from cleaning equipment, cleaning consumables, cleaning training, cleaning institutions to those home appliance cleaning chain stores in various cities, of course, not only these, but also housekeeping services have also carried out home appliance cleaning services, and even roadside stalls have home appliance cleaning services. In recent years, the Internet has developed rapidly, and there are many platforms on the Internet about home appliance cleaning, so that customers can make an appointment to the home appliance cleaning service at any time.
Because this industry is developing rapidly, the service specifications and service technology have not reached a unified standard, the standards of each family are not the same, and the technology of each master is different, resulting in the service that the majority of customers can receive is also different. Just like the picture above, many people think that cleaning is not necessary to dismantle into this, directly discharge the sewage outlet to rinse a few times, such a simple thing, is a man will, why waste money to ask the master.
Wash the water heater
Yes, it is to rinse a few times on it, that is estimated to be equivalent to not cleaning it yet, you look at these scales attached to the heating tube so tightly, knock can not knock off, you rinse twice can come out? Maybe only you believe it, but I won't believe it anyway.
A whole bunch of limescale
Maybe what seems easy in your eyes is particularly difficult when I do it, because it is really not easy, I did not believe that the small sewage outlet can discharge this big pile of scale, these 20 pounds of scale is not rinsed two or three times can be washed down. Because I have been on the first front for more than ten years, cleaning more than 6,000 electric water heaters, I have seen too much and too much, from the sewage outlet to rinse with water to clean, at most can only deceive the user can also, want to deceive me, kill me I do not believe.
The scale on the heating pipe can't come down
At present, the popular electric water heater cleaning methods are mainly as follows:
First, the flushing method: directly open the sewage outlet, let the dirty water and scale flow out of the inner tank of the electric water heater, rinse three or five times repeatedly, and the water that flows out is slightly clearer, and then it can be done. This cleaning method is simple, the fee is very low, the user likes it, the master also likes it, after all, the simple operation of the RMB is in hand, and both sides think it is worth it.
Second, the syrup cleaning method: directly put the descaling agent into the electric water heater, some masters take the cleaning machine irrigation, some masters take special tools to irrigate, the purpose is to fill the descaling agent inside, and then use 40-60 degrees of water to soak in the electric water heater, about the soaking time is about 2 hours, of course, the longer the soaking time, the better, the user with time can soak a night is the best. Then open the sewage outlet, use water according to the first method to rinse the scale and drug residues inside, this method can not be washed clean depends on the level of the master, but there will be drug residues, it is difficult to clean clean, while the acidic environment of the electric water heater liner, heating pipe and water pipe will be damaged to varying degrees.
Third, ultrasonic cleaning method: this method is very high-tech, but not as good as imagined, the use of sound wave high-frequency oscillation signal resonance to make the scale fall off, and then according to the first method of flushing, in fact, this ultrasonic used to clean the inner wall of the water pipe those things are OK, but cleaning the scale of the electric water heater That effect is really not good.
Fourth, high-pressure water gun steam machine cleaning method: There are many machines dedicated to cleaning electric water heaters and other home appliances, most people use the function of high-pressure water guns to flush electric water heaters, in fact, the effect is not good, after all, in a closed space to clean these, there is not much effect, once I also spent 3999 yuan to buy a cleaning machine, could have made a lot of money, the result was only used three times, it was thrown away, because first use the machine to wash, and then disassemble the cleaning, found that many of them were not cleaned, So just throw it away.
Fifth, the dismantling machine cleaning method: this method of cleaning the effect is the best, and the user can directly see whether the electric water heater inside is clean, but this cleaning method takes a long time, generally an electric water heater to clean down, it takes two hours, and the technical requirements are a bit high, because the heating pipe is removed to clean, many accessories must be removed, if there is no maintenance technology, it is recommended not to use this method to clean, because it is possible to wash the electric water heater, so the risk is high. So I use this method to clean, so far has been cleaned more than 6,000 units, did not encounter cleaning bad, even if encountered bad, but also on the spot to repair.
We all know the above cleaning method, as for what kind of method, we can choose according to their own needs, before that, there is a very important point, that is, we do not know when the electric water heater should be cleaned, this is the most important, I suggest that you dismantle the magnesium rod once in two years, discharge the sewage, very dirty is should, but if there is a lot of scale found inside, that is the time to clean, if only sewage, whether it is black, yellow, did not find a lot of body scale, I don't think there is any need to clean.
Why is there no need to clean it? Because the scale of the country is not the same, the hardness of the water in some places is very large, and the water in some places is very good, so some places estimate that two or three years must be cleaned once, otherwise it will affect the normal use of electric water heaters, but some places estimate that there is no need to clean it for ten years, so according to reality, do not blindly clean the electric water heater.
Yesterday in the group there was a master in the circle of friends to send a cleaning effect, look at it, this electric water heater is the user first asked someone to use the medicinal water cleaning method to clean once, three days later, and then asked someone to dismantle the machine cleaning, the heating tube is removed, the result has been clear, I don't want to say which method is good, but the picture has explained everything.
There are many ways to clean the electric water heater, I only choose the method that is worthy of myself and the user, because I am doing cleaning with conscience.
