Chapter 115 The Water Turning Wheel and the Fire Pit Bed{3}

After Su Shang took the small notebook and pencil, he asked the man to bring a small table and draw the design directly next to the fire pit bed!

"It's no problem now, it seems that I, Su Shang, am really a science genius!" Looking at the drawings in his hand, Su Shang was very satisfied, and he was still shameless in his heart, and he secretly praised himself.

This drawing was redesigned by him after practicing with the fire pit bed! When he was at his grandfather's house in the dream world, he often saw the fire pit bed, but he had never seen how the fire pit bed was built, and he didn't know what the inside of the fire pit bed looked like, he always thought that the inside of the fire pit bed was heated directly under the bed board with firewood, so when he drew the drawings of the fire pit bed for the first time, he didn't think much about it, and directly drew what he took for granted, and then it was over.

This time, he drew the drawing of the fire pit bed, he had already thought very clearly, very thoroughly! The reason why the bed board of the previous fire pit bed was unevenly heated was because when burning the fire pit, the firewood was concentrated in the middle of the fire pit, and the flames were always burning in the middle of the bed board, so it also caused the temperature in the middle of the bed board to be too high, and the edge part was still cold.

Su Shang is going to directly heat the fire pit bed from firewood to steam heating, completely transform the part under the bed board of the fire pit bed into a sealed tunnel, and the part heated by the fire pit will be moved away from the fire pit bed and put outside, built into an independent wood stove, and a boiling water porcelain tank is set on the wood stove, and then by building a closed tunnel, the boiling water porcelain tank is connected and sealed with the pit of the fire pit bed!

In this way, when heating the bed board, you only need to add firewood to the firewood stove outside the pit, and then boil the water in the porcelain tank, and the vapor of the boiling water will pass through the sealing pit and directly penetrate to the bottom of the bed board to evenly heat the bed board, and the water vapor will flow back to the boiling water porcelain tank through the sealed pit after the endothermic liquefaction of the bed board, and the steam circulates continuously in the tunnel, which can not only reduce the number of times you add water, but also make more effective use of the thermal effect of steam!

"That's it! I've already drawn the drawings! Come and see, and I'll tell you what you need to pay attention to in this new fire pit bed! Su Shang checked the drawings several times to confirm that there were no more inappropriate problems with the drawings, and then drew more than ten copies of the drawings before he opened his mouth to beckon everyone to come over!

"This book is too small.,The pattern is also small.,One for one person.,It's all the same! Brother Yunqi, after you go back, you can find someone to redraw a few big ones according to this drawing! Su Shang distributed the drawings to everyone one by one!

"Yes! Yunqi will do it when he goes back! ”

"Brother, where are our drawings?" Xiao Xiao was a little dissatisfied and shouted loudly. It turned out that everyone present, including Cui Qingying's master and servant, were all assigned a drawing, but she and the little girl didn't!

"You are a child, and you can't understand it! What are you coming for? Su Shang glared at Xiao Xiao and said, "Go!" Let's play with my little sister first! Otherwise, when my brother goes back, he won't make you anything to eat! ”

"Bad brother! Nasty brother! I know how to bully the little ......" The little puffed out her little mouth, led the little girl with her right hand, shouted quietly all the way, and ran to the side aggrievedly!

Everyone couldn't help but laugh when they looked at the appearance of Su Shang's brother and sister, and Cui Qingying's master and servant even raised their hands to cover their mouths and snickered!

Among all of them, the only people who have really come into contact with Su Shang are Wei Yunqi and Cui Qingying's master and servant, and the others, at most, have seen Su Shang from a distance, and their impression of Su Shang has always been to hear his name but not see him! In their hearts, they have always thought that Su Shang is an iron-blooded and ruthless general, and they feel that Su Shang must have been gloomy on weekdays, with a deep calculation and a look of rejecting people thousands of miles away.

They were all surprised, they didn't expect that the real Su Shang was completely a super competent brother, so warm and full of human feelings!

"Everyone's attention! Looking at the drawings, I'm going to tell you about this new fire pit bed now! After Xiaoxiao took the little girl to the side and played happily, Su Shang opened his mouth again to greet everyone.

Everyone smiled and looked at the drawings with a straight face, waiting for Su Shang's explanation, Cui Qingying and Xiaoyuan were the same, looking at the drawings in their hands seriously, listening attentively.

"Actually, it can't be called a fire pit bed anymore, it's more appropriate to call it a steam bed! Because I have changed it from directly heating the bed board with firewood to heating the bed board by steam, the advantage of this change is that the steam can heat the bed board more evenly, and the temperature of the bed board can be avoided from rising too quickly and too high! ”

"The construction of a steam bed is not difficult or complicated, so I won't say more. I'm sure with your ingenuity, it will be easy to understand how this steam bed was built. As long as the steam bed is built, it is built in strict accordance with the design drawings! ”

"I'm going to tell you about the problems that need special attention during the construction of this steam bed, as well as in the process of use! First, during the construction process, the inside of these steam tunnels must be built with stones as much as possible, the inner walls of the tunnels should be polished as smooth as possible, and the sealing of the tunnels should be good and there should be no air leakage! ”

"Wait two, there is a black mark on the drawing, this position is a vent, but also a water hole, after the steam bed is built, it should be blocked with a relatively light stone plug, not too tight, to ensure that it can be easily picked up! You can also use something like a cork, but make sure it can be picked up easily when the water rises! This is very important, you must remember that you must not let it be blocked, otherwise it will be very dangerous, and it may cause vapor bào zhà, which will lead to the collapse of the house! ”

"When we use the steam bed, we must not be pressed by things, and when we heat the steam bed, every time we see this plug constantly beating out, the wood stove should stop burning, and we can wait until the plug is no longer beating and emitting hot air, and then continue to heat the fire."

"That's it! There are probably so many questions that should be paid attention to, if you still have any questions, what you don't understand, you can ask them now! ”

Everyone didn't speak, they were still staring at the drawings and thinking, still digesting what Su Shang said! Instead, the little round girl stepped forward and saluted Su Shangyingying, "Master Su, what is the steam bào zhà?" ”

Everyone looked at Su Shang one after another, obviously they didn't quite understand what this steam bào zhà meant! Su Shang looked at everyone, and then remembered that the word steam bào zhà is a physical term for the dream world, and now in this world, I don't know if the word bào zhà has been created!

Su Shang thought for a while, looked at everyone, and said with a smile: "I think everyone knows that when boiling water in a kettle, after the water in this kettle is boiled, as long as it is heated all the time, it will keep emitting white water vapor until the water in the kettle dries out."

"When the kettle is boiling water, the steam can beat against the lid of the kettle and even drop the lid to the side! It can be seen from here that this steam is not only very hot, but also very powerful, the steam is like these steam has been blocked in the kettle and can't come out, and then suddenly the whole kettle is propped up by the steam 'bang' and bursts directly, such a bào zhà is very powerful, not only the temperature of the steam is extremely high, but also the power of the exploded kettle fragments is comparable to a boulder, if there is someone next to the kettle, this person will not be able to withstand the power of this bào zhà! And the power of the steam bed bào zhà will be ten times more powerful than this, a hundred times! Therefore, when promoting the use of this steam bed by the people, we must remind them to pay special attention to this stomatal plug, and they must not let it be blocked! ”

"President, can this firewood stove only be used to cook steam in winter, can it be used for other purposes in normal times, after all, in the people's homes, if this firewood stove can only be used in winter, it is estimated that the people may be very distressed!"

"Absolutely! You look at the drawings, this position on the boiling water porcelain jar can not be sealed, usually when the steam bed is not used, you can use something to block the steam tunnel, and then this boiling water porcelain jar can be used casually, cooking rice, boiling water, and so on! ”

"My lord, does this steam bed need to be heated by a wood stove all the time when it is in use? Will it be hot then? If the water in the porcelain jar is boiled dry, how do we add water? ”

"That's a great question! These are all issues to pay special attention to! ”

Su Shang looked at everyone, and then said: "First, the firewood stove does not need to burn all the time, after the steam bed reaches the right temperature, you can close the stove door and stop the fire, however, in order to prevent the temperature of the steam bed from dropping, the firewood stove can open the stove door every once in a while and put some charcoal to burn, the charcoal does not need too much, and the temperature of the steam bed can be kept from dropping!"

"Second, this is also something to pay special attention to! It is dangerous to fill the porcelain tank with water in the middle of the use of the steam bed, so before each use, fill the porcelain tank with water. If you use it continuously for too long, you must remember to add water to the porcelain jar and not let it burn dry! When adding water to the porcelain tank halfway, it is necessary to temporarily stop the fire, and then use something to open the plug of the pora, when opening the stopper, the personnel should be far away, never too close, and can not hold the plug by hand! When the plug is opened for a period of time and the air hole does not continue to heat up violently, then you can be careful and add water to the porcelain tank. ”
