Siheyuan: I am Yi Zhonghai's biological son

The Yi family had a very lively Spring Festival this year. Considering that Meng Xiaoting had just married and they were afraid that she would not be used to it, the Yi family did not celebrate it with Sha Zhu's family this year.

Yi Zhonghai was particularly happy this year. He already had a daughter-in-law, so how long would it take for a grandson to arrive? On New Year's Eve, Yi Zhonghai gave Meng Xiaoting a big red envelope.

During the first day of the new year, an aunt took Meng Xiaoting to meet the people in the courtyard. In the past few days, she has been telling her about the personalities of everyone in the courtyard, and she described them in more detail than Yi Pingan.

Meng Xiaoting also met He Yushui again and greeted him calmly. There was no tension as imagined. For Meng Xiaoting, she had already won by filling in her name in the spouse column of Yi Ping'an. There was no need to add insult to injury and make herself look very petty.

Yi Ping'an likes this kind of wife of his. She can be very jealous, but she also handles things clearly and is gentle but also resolute. Only with such a wife can he leave with peace of mind.

On the second day of the Chinese New Year, Yi Ping'an left again. Meng Xiaoting smiled and sent him out the door. When she turned around, she was already in tears. She had experienced too many separations, and she understood that tears should not be left to men, as it would make him worry. She was a strong woman.

After wiping away her tears, she became the omnipotent Meng Xiaoting again.

Yi Pingan returned to the research institute. This year, his research project is the fully automatic washing machine. The earliest fully automatic washing machine was invented by Xiao Rizi in the 70s. How could he tolerate this? He had to make it first.

With the previous centrifuge, washing machines are relatively easier to make. The difficult part is the automatic control system. But with the previous experience, the difficulty for Yipingan now lies in how to make the control system smaller.

The circuit board needs to be integrated, so you need to draw it yourself. Just knowing the technology is useless, mainly because of the limited materials. Yi Pingan had to seek help from Group 101. With the help of the experts in Group 101, Yi Pingan spent three months and finally made the first integrated circuit board. Compared with later generations, it is still much bulkier, but now it is the smallest level that can be achieved.

The research institute is not only a gathering place for talents, but also has the most advanced equipment and the most complete materials. For people with strong hands-on skills, it is simply a paradise.

In fact, in 62, the Fengtian Daily Appliance Research Institute in my country developed the first washing machine. This washing machine was semi-automatic, which means it had no inner drum. Without an inner drum, there was no spin-drying function. Later, after a technological breakthrough, the later double-barrel washing machine was developed. Such washing machines were still in use even in the millennium.

The first fully automatic washing machine was developed after the reform and opening up. Yi Pingan remembers that the brand at that time was "Little Swan", which later became the world's third largest washing machine manufacturer, demonstrating China's rapid development and international competitiveness in the field of home appliances. In this life, Yi Pingan wants to make it 15 years earlier and make life miserable.

The first thing Yi Ping An made was the inner cylinder, which is the simplest centrifuge. After the power inner cylinder was completed, the electronic control system was installed, and then the data was tested. Not only did it have to rotate, but it also had to be able to clean. This required testing bit by bit, and the time had to be controlled well, with the whole process not exceeding 45 minutes.

The researchers in the institute are very happy these days. How can they not be happy when someone washes their clothes? Especially the people in the chemical engineering group, their clothes are always stained with strange things and difficult to wash. Now people come to them every day to find dirty clothes.

At first they were a little embarrassed, but later they realized that they were just doing experiments, so why should they be embarrassed? We are contributing to scientific research. Clothes are nothing, we can also contribute bed sheets, etc., do you want to contribute?

Yi Ping'an had seen fully automatic washing machines, so it was even easier for him to make one. As long as the materials were good, there would be no problem getting started. In July, Yi Ping'an finally made the first fully automatic washing machine.

Even though Yi Ping'an has tried his best to be beautiful, it is still a bit bulky compared to his previous life, but it is much more delicate in this era.

On the day of the finished product test, everyone in the institute who knew about this came to see the washing machine made by Yi Ping'an. This was a new thing, as they had never seen a machine that could wash itself from start to finish.

When you throw clothes in, you watch it move, knowing when to add water, when to add detergent, when to shake it out, and finally when it's done washing, it sounds the alarm. Everyone thinks it's incredible, it's like a spirit, completely freeing up your hands, it's amazing.

"This is incredible, this is amazing, is this what modernization looks like?"

"Yeah, how does it know to add water or drain water?"

People from Group 101 also came. They mainly wanted to see what the electronic control system looked like in actual use. Is this what it looks like?

The leader of 101 patted Yi Ping'an on the shoulder and said, "That's amazing!"

Yi Pingan smiled and replied: "Is that amazing? If the material allows, a drying system can be added so that it can be worn directly after being taken out. It's a pity that we haven't made this breakthrough yet. This can be used as an idea and we can continue to work hard to make breakthroughs."

Someone nearby replied, "Engineer Yi, everyone says that you have an unconstrained mind. This time it seems to be true. You have all these weird ideas in your head. But your experiment this time has given us new ideas. It turns out that our thinking is too narrow and we haven't let go!"

"Engineer Yi, I'm from the chemical group. Thank you for helping us wash clothes during this period. Please come to our group often. I know you understand chemical engineering. Don't refuse. We want your ideas. Can you give us more new thoughts? I'll treat you to a meal. How about braised pork?" said the staff from the chemical group.

"No problem. Let me make it clear first. The braised pork cannot be missing. Otherwise, I won't wash your clothes in the future. Your group's clothes are the hardest to wash in the entire institute."

Yi Ping'an said with a smile, but he felt sour in his heart, "Red-braised pork" is such a plain word, but you have to know that this is a big beef, a specially supplied big beef, and red-braised pork can become a luxury, which shows how poor our country is now, we have to make money, we must make money.

"Hahaha" everyone around laughed.

At this time, Director Liu also came over, and Yi Ping'an demonstrated the working process of the washing machine to Director Liu again. After 45 minutes, the washing machine finished working. The director took the clothes inside and looked at them. Hmm? They are washed quite clean and half dry. They can be worn directly, which is very convenient, especially in winter.

Director Liu was very happy and asked Yi Ping'an to make a few more machines, trying to have one for each group. Such machines are very convenient to use and can dry clothes quickly.

The staff present all applauded after hearing this. Although they all have assistants, they will not bother the assistants unless they are busy. In a socialist society, everyone is equal. How can we let the assistants do the work of a nanny? Now that we have a washing machine, at least we don’t have to wash clothes by hand anymore. How convenient!

With the experience, everything went much more smoothly afterwards. In less than half a month, Yi Ping'an had made a washing machine for every group in the institute. Even after he became proficient in the work, he found that it could be improved further, so he delayed some time. Otherwise, it would have been even faster.

After Yi Ping'an finished all this, he put the project summary report and the complete set of drawings of the washing machine in a file bag and sealed it. This meant that his project was completed and he could start the next project.

"Leader, this is the plan for the washing machine project. It's all here." Yi Ping'an said as he handed over the documents in his hand.

Then he said, "Leader, I suggest that this project should apply for a patent as soon as possible, so that we can use the channel over there in the port city to earn foreign exchange."

"Mr. Yi, I will report your suggestions to the higher-ups. Many of the projects you have undertaken can earn foreign exchange, such as the boiler and now the washing machine. That's great!" Director Liu said happily.

"Making money from foreigners is the way to increase revenue. We don't have any money ourselves. We use their money to make guns and weapons, and then beat them back. Does this count as returning the property to its original owner?" Yi Ping'an also said with a smile.

"Hahaha, that's right, the property is returned to its original owner!" Chief Liu laughed, as if he had seen that day.
