Coquettish Rebirth

"Hiss... Is it technically possible? It may be difficult..." There is no need to find a special engineer. Just after Jia Hongjian thought about it, he found that the fully automatic all-in-one rice cooker he envisioned had certain technical problems—— — Let’s not talk about anything else, let’s just wash the rice and wash the rice. How can this thing be realized?If there are no impurities in the rice and there is only a layer of "rice flour", then the rice washing place can be designed to be similar to a washing machine.It is possible to install a flower-like protrusion at the bottom of the rice-washing tank that can rotate to drive the water flow, but the problem is, how to let the water out after washing the rice?In the principle of the washing machine, the water flow is driven clockwise and counterclockwise. Through this movement, the clothes are rubbed against the water flow by inertia, and then the stains on the clothes are separated from the clothes, so as to be washed.But how does the water get out after washing?It turns out that there are small holes around the washing bucket. Outside the washing bucket, a larger bucket is covered. Through various designs, these small holes do not leak water when stirring and washing, and then the washing is finished. Let the small hole leak, isn't it over?The outer cylinder can collect the water that flows out, and then discharge it through the pipe to the sewer.

The washing machine is such a principle, but the rice washing machine can't play like this!why?Because clothes are such a big thing!Even if you wash it in the washing machine, it will always be much bigger than the small hole on the wall of the washing bucket, right?Therefore, after washing, turn on the water, and the clothes will never flow out with the water flow!But how big is rice?Even some cheap rices have broken rice in them!The size of this broken rice is not necessarily easy to control!At this time, how big a hole should be made on the wall of the barrel to stop the rice from going out with the water?Even if the small hole we made is only the size of a needle tip, the rice grains will never go out, only the water will go out.But the problem is that washing rice is different from washing clothes!The main reason for washing the rice is that the rice may be mixed with the peeled skin and some small stones and sand!What are the stains on clothes?Mainly sweat stains, etc. The stains on the clothes are not solid, not all kinds of small stones!

So, if you make the drain hole in the rice washing bucket only the size of a needle tip.So, isn't it that when you wash it, you can't even get out things like rice bran?At that time, the rice washing water will run away, and the small stones and sand will be kept together with the rice. How bad will it be to make rice with this thing?Even if there are no stones every time, it is unbearable to come once or twice - after all, such a gadget is called a smart rice cooker, it can't even remove a stone, and the efficiency is not as good as human Wash rice by hand.Can this thing be called smart?The new so-called smart products must perform better than manual rice washing. Otherwise, even if they are already quite progressive in concept, for ordinary people, they will feel that they are spending a lot of money as a A guinea pig!There is definitely a feeling of being cheated!

Once consumers feel that they have been cheated, the damage to the brand will be considerable, and the result may be that other products of Huaxia Hi-Tech will gradually be distrusted, which will bring about quite a big problem!After all, consumers have begun to lose confidence in Huaxia High-tech products, which means that at a certain point, even if our products are really good.There is no way to become a hit, and it must be slowly won word of mouth, so that people who doubt it will gradually know that this product is really good, so that it can slowly sell well.Isn't this undoubtedly adding a lot of difficulty to myself?So how to do this thing?If there is no small hole for water leakage, how should this "rice washing machine" be designed in principle?Or learn a front-loading washing machine?

This type of drum washing machine is rarely used by Chinese people. Even Jia Hongjian and his family actually use a more traditional vertical washing machine instead of a drum type.So can the principle of drum washing machine give us any inspiration?Jia Hongjian searched for the principle of the front-load washing machine, only to find out that this thing is a bit of a return to basics—although the principle of the front-load washing machine is similar to that of the vertical washing machine, except that the drum is laid flat.But when the upright washing machine works.It just relies on the reciprocating motion of the water flow to rub against the clothes to peel off various stains, but this drum washing machine is different-because of the gravity factor.So when the drum washing machine is rolling, the clothes will definitely be rolled up by the drum and then fall down!In this way, it actually has an effect similar to that of ancient women hitting with a mallet when washing clothes!

That's right, in fact, regardless of China or foreign countries, when people wash clothes, they find that beating is a good way of cleaning.By beating, it is easy to get the stains out of the clothes, so that the washing is cleaner!Even the washing machine that had nothing to do with electricity was just invented in the 19th century.Then someone designed such a washing method that a movable wooden stick continuously hits the clothes!The drum-type washing machine just cleverly uses the action of the drum to complete the action of beating. Of course, such a mode in which the clothes are rolled up by the drum and then dropped, the beating effect is natural. The effect of beating with real people is not good.But it is definitely better than the pure stirring method of the vertical washing machine!

But this kind of drum washing machine is not without disadvantages - the biggest disadvantage is that basically after the washing machine starts to rotate, there is no way to add clothes into it, because the drum is horizontal after all, if the door of the washing machine is opened at this time, the water will not flow Flow all over the place?Therefore, if some models are designed to add clothes, they must stop the operation and then drain the water, and then add clothes, and some models even do not add clothes at all!At the same time, because of the principle of this drum washing machine, it is actually very slow to wash clothes.Because it is like a vertical washing machine or a pulsator washing machine, the principle is to make the water surface higher than the clothes, and rely on the eddy current and inertia caused by the pulsator reversal to peel off the dirt on the clothes.But the drum washing machine itself does not mainly rely on water, and even too much water is not good-if there is too much water, the clothes will float up, how can the drum roll the clothes in the air and then fall off?At that time, wouldn't the clothes be kept parallel to the ground forever with the water?So in fact, when the drum washing machine is running, the water just soaks the clothes, just simulating the effect of women putting clothes on the bluestone on the bank and then beating them when washing by hand!

So even if the drum washing machine is cleaner, the actual time it takes is doubled—like a vertical or top-wheel washing machine, it can be fully automatically cleaned in about 40 minutes, but the drum washing machine basically needs to be cleaned. 100 minutes to 120 minutes!That is 2 hours!It takes two hours to wash clothes. Is this crazy?Especially when you find that there are clothes that have not been put in after you start washing!And after the clothes are washed, they still have to be dried. People have to wait two hours to dry the clothes?So this rolling washing machine has added a drying function after a lot!If you want to use this function to let consumers throw clothes in, don't worry about it!

But having said that, Jia Hongjian looked for a photo of the drum of this front-loading washing machine, and found that there were many small holes in the wall of the drum to put water in the horizontal drum!After all, clothes are different from other things, they are always bigger!In this way, can't this drum washing machine also be used for reference?then what should we do?Suddenly, Jia Hongjian remembered some of his experience when he helped the family wash rice. Historically, in the 90s, Jia Hongjian’s faucet installed a shower device similar to the shower head in the bathroom. The water coming out is the same as that without a shower, and it can also be sprayed from several water lines like the shower head in the bathroom.Then Jia Hongjian washed rice, using both types of water flow.With the usual water flow, after the water has rushed into the inner pot of the rice cooker for a few seconds, Jia Hongjian stops the water directly, and then tilts the inner pot to pour out the rice washing water with some floating objects. At this time, the rice grains still sink to the bottom of the water, and only a few rice will float on the water surface.Then do it a few more times, just pick out the pebbles you see.

But if you use the shower mode, it is different. If the water in this shower mode is relatively large and the pressure is relatively strong, most of the rice grains will float up—it must be because the water flow is divided into several water lines. After the water line rushes into the inner tank, it collides with the inner tank, and at the same time, the water flow also collides with each other due to different angles, so a large number of eddy currents are generated, and it is easy to turn the rice over.In this way, if Jia Hongjian's usual habit of turning off the water and pouring it out, it would be easy to pour out a lot of rice along with the floating objects!Then if we use this principle, can we design different water spraying methods to make the height of the rice in the water different to remove different types of impurities?

For example, first release the water in a moderate mode, and at the same time, the container holding the rice vibrates to a certain extent to get out the floating objects hidden in the rice, and then drain the water, so that the floating objects follow.Then increase the pressure and at the same time use the eddy current in the shower mode to make the rice float as much as possible, and use the weight difference between the rice and the stones to achieve the effect of separating the rice and the stones?It's just that such a design seems to be troublesome, and there is still a problem, how does the washed rice get into the inner tank for heating?You can't make the liner full of holes like the liner of a washing machine, can you?Thinking of this, Jia Hongjian felt that he could think of an immature solution. Logically speaking, a professional engineer should be able to think of other methods for automatic rice washing?After all, Jia Hongjian is not a professional, we still have to let the professionals figure out whether it can be realized!
