Coquettish Rebirth

Jia Hongjian still had no idea what to do with the smart washing machine.Ideally, he thinks that such a smart washing machine should have the function of automatically identifying the material of the clothes, and then automatically select various washing methods.In this way, the washing machine is made more intelligent, so that users can operate more foolishly.With the function of automatic weighing and measuring the volume of clothes, it can save more water and electricity without damaging the clothes. It can be said that it is an ideal washing machine!As for whether it can be connected to the Internet or not, it really doesn't matter!After all, how can the washing machine be connected to the Internet?The function of this thing is more simple than that of a refrigerator. What storage function does a refrigerator have, and it also involves the problem of food preservation for a long time? This washing machine is only for washing clothes, and it lasts for two hours a day. Hey, what's the use of networking with this thing?

On the contrary, Jia Hongjian felt that it was necessary to realize the function of automatically distinguishing the material of clothes, but it was difficult to realize.For example, in some relevant domestic academic research, some scholars published an article four or five years ago, saying that if the washing machine in the future needs to develop the function of automatically identifying the material of the clothes, it can rely on the intelligent identification technology rfid for identification.What kind of "intelligent identification technology" and what kind of "rfid" is it? It sounds very high-end, but it is actually very simple-to put it bluntly, it is the same design as the bus card community access card, just get a chip!It is to obtain the information of the clothing material by scanning the radio frequency signal!So how can there be radio frequency signals on the clothes?It is necessary to get a small radio frequency chip into the label of the clothes!

This sounds like a bit of a gimmick?In fact, there is no trick at all!First of all, let alone whether the chip will fall off during the washing process after doing this, why do various clothing factories put a chip in their clothes labels?This chip doesn't cost money?Don't want to spend money on other manufacturers, don't they think it's troublesome?Will it increase other people's processes?And if the manufacturer outsources clothing labels in batches and then buys them and puts them in the warehouse, can the storage conditions of labels with chips and labels without chips be the same?Isn't this an extra cost?Besides, with this kind of chip, people can't make more money.It cannot be said that what they make is smart clothes, so consumers need to spend 30 or 50 more.Consumers will still think at that time, this clothes will cost 35 cents more because of multiple chips?Isn't this nonsense, I don't want this smart function, I want ordinary tags, you give me 35 cents cheaper!

That's right, consumers are often so picky!When it comes to buying a washing machine.Consumers are very happy when they hear that this washing machine can automatically identify clothes, but they are not happy when they hear that an extra [-] to [-] chip fees are required to buy clothes!In fact, to put it bluntly, it is best to have such a function, and it does not matter if there is such a technology.After all, the majority of people in the world are ordinary people. Whose clothes in these people's homes are precious and must be washed according to the material of the clothes?They all know to take really expensive clothes to dry cleaners to wash, who would put them in the washing machine!So this creates a problem, if such a function makes consumers pay.Especially if consumers are asked to pay for clothes, consumers will not be happy!

And there is another problem, that is, we can't get such a label on clothes all over the world!Even if we subsidize and let clothing factories around the world purchase our chip tags not only do not charge money, but also give them money, so that even within a year or two, new clothes produced all over the world will have radio frequency tags. Where are your clothes?So that is to say, even if we invest a huge amount of money in subsidies for a while, the final result is that our product can only play a role slowly with the passage of time!I met people who bought less clothes.That is, there may not be any results within three to five years, and people will not be able to use this function in three to five years!

Not to mention such a practice if we eat alone.Then it is easy to be suspected of unfair competition - to subsidize downstream manufacturers to let them produce products suitable for our functions, and then stimulate consumers to buy our products... This matter can easily be caught as a typical case of anti-monopoly in foreign countries. !Unless such a radio frequency tag is made public and made into a public function that every washing machine manufacturer can use, then it will become us to pay for everyone to enjoy... Why?Even if we want to establish an alliance or something, and then find all the washing machine manufacturers, and everyone will bear the subsidy cost according to the market share.That's a bit of a joke!Maybe some people think that their market share is so big whether they pay for it or not, and they think that this function is too much, not much, and then they are dragging their feet. Then such an alliance is established to be true. To be able to subsidize, that's really something to wait for!

Although it is easy to do things with many people.But many times the same people talk too much!Moreover, everyone is still a competitor, and everyone feels a little bit like a feud with each other. At this time, let everyone put down their small calculations and unite?At least Jia Hongjian didn't have confidence in this, at least he thought it was impossible to do it in a short time!

How should we do it?Jia Hongjian thought about it, even in his family, not all the clothes were expensive clothes.Like the t-shirts and jeans that you wear every day, many of them are cheap brands for ordinary people!Not to mention his house, even Bill Gates' house, there are still a lot of cheap clothes!After all, it is impossible to wear a top pajamas tailored by a top tailor on the bed while sleeping, right?It's impossible to say that when you play basketball, run, etc., you still wear all kinds of high-end leather and silk top-cut high-end clothes?Isn't this nonsense?So to be honest, it will be thrown in the washing machine for washing. In fact, most of them are ordinary clothes.Therefore, Jia Hongjian felt that such a function of radio frequency identification material should be temporarily abandoned—at least the method of realizing material identification through chips should be given up!

Maybe you can get something like a dot reader for tag recognition?Basically, clothes that are a little more serious and not so fake will have materials and ingredients written on their labels. In this way, if we make a window on the operation panel of the washing machine that is similar to the window for reading barcodes in other supermarkets, put Put the label on the clothes and wait for a few seconds, then can the microcomputer read and identify the material written on it?Jia Hongjian thought it was worth a try, because Huaxia Hi-Tech started making all kinds of Wenquxing and even point reading machines more than ten years ago?At that time, Ni Guangnan and other old men began to study the pen-shaped point-reading machine, and recognized the English words on the book through the instrument of the pen, and then displayed their pronunciation, meaning and even read them aloud.Now that it is possible to analyze English before, let's start to study whether Chinese recognition can work?

This matter can be discussed with Mr. Ni later, but at this time, Jia Hongjian thought of another function - the quality of tap water in various parts of our country is different, and in some places the water quality is relatively hard. After a year, the bottom of the pot is covered with a thick layer of scale.To put it bluntly, scale is actually calcium salt and magnesium salt, which is the stuff after minerals are dissolved in river water, lake water, etc.!Then when the water is boiled, calcium sulfate, calcium bicarbonate and the like are decomposed by heating and become insoluble things such as calcium carbonate, and finally precipitated.So what does this kind of hard water have to do with the washing machine?The relationship is that things such as magnesium and calcium in hard water will reduce the effectiveness of detergents!

For example, if washing clothes with soap in hard water, then because the calcium and magnesium ions in the water combine with the soap, a flocculent precipitate of fatty acid calcium and fatty acid magnesium is formed, which is the origin of "tofu dregs".Even not just soap, like washing powder, when washing clothes, if the hard water is not softened, the washing effect will still be affected due to the quality of the hard water, and more washing powder is needed!Later, under foreign research, a builder was added in addition to the surfactant of the washing powder. Such a builder was originally phosphate!Such a phosphate will react with calcium bicarbonate and other things, thereby enhancing the laundry effect of the surfactant, that is, the detergent itself!

As for the modern so-called phosphorus-free laundry detergent, in order to avoid the oxidation of the water body caused by the phosphate being discharged with the washing water, a phosphorus-free builder appeared, and this phosphorus-free builder To put it bluntly, it is also used to soften the water body.How did Jia Hongjian think of this?He thought of this because the water quality in different places is different, so in theory, if you want to make washing powder play the most effective role and wash clothes with the least cost per unit weight of washing powder, you must choose according to the different water quality in different places. Arrange the proportion of the builder!Otherwise, there may be problems of insufficient builder or excessive builder!It is impossible for manufacturers to arrange washing powder specially sold in different places according to the water quality in different places!They can only make a recipe that satisfies the majority of people as much as possible, or that is almost enough, and they are done!And ordinary people may actually spend more money on washing powder, but it takes less time than the most economical way in theory!So can we automatically detect the water quality through the washing machine, and then adjust the proportion of detergent builders?

Of course it is possible! (To be continued..)
