The structure of the flush toilet is very simple, and the Englishman John Harrington invented the flush toilet in the 16th century. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoIn 1775, a watchmaker named Alexander Cumming in London improved Harrington's design, invented a valve mechanism, and developed a flushing toilet, which was patented for the first time.

As an industrial designer, Li Zhi certainly knows the structure of a flush toilet. For Li Zhi, drawing a diagram of the structure of a flush toilet is very simple.

The water tank switch of the flush toilet is very simple, and with the design drawing drawn by Li Zhi, it is basically done by a qualified coppersmith. Although there was no plastic in this era, copper could be used instead.

The ceramic body of the toilet is not a difficult task. In this era, the Ming Dynasty has been able to make all kinds of ingenious porcelain, and firing the toilet barrel is also a piece of cake. Li Zhi found Cai Huaishui, handed him the design drawings, and asked him to find a few reliable porcelain craftsmen to make barrels.

There are porcelain burners in Tianjin, and it only took seven days for Cai Huaishui to find someone to burn three barrels.

Li Zhi dug a pit in the glass workshop, assembled the burned toilet barrel and the copper mechanism made by the coppersmith and installed it on the pit, and the first flush toilet in the Ming Dynasty was born. Li Zhi threw a few balls of waste paper into the toilet, and as soon as he pressed the button and flushed, the paper balls were flushed into the puddle under the toilet.

Although there was no running water in this era, well water was readily available. There is a well dug for every ten villas in Fanjiazhuang. Before using the flush toilet, the user needs to carry a bucket of water and pour it into the ceramic bucket at the upper part of the flush toilet. Because of the use of manual water filling, there is no need to do the float in the toilet tank. This float is the most complex part of the entire flush toilet technology, and not producing the float can save a lot of costs.

For flush toilets, it is important to fix the toilet, and the pipes must be aligned with each other. The cement produced by Li Zhi came into play at this time. As long as the barrel of the flush toilet is fixed with cement in the toilet, there is no problem that the barrel body is shifted and cannot be used.

After this new type of toilet is mass-produced, it will be sold to the people of Fanjiazhuang first.

There are septic tanks dug under the villas in Fanjiazhuang, and installing a flush toilet does not require the sewer to be renovated. Li Zhi gave a preferential price to the people of Fanjiazhuang: as long as you hold the waist card of Fanjiazhuang residents to buy a flush toilet, the price is as low as two taels. This price also includes the installation fee and the cement material fee, as long as you pay two taels of silver and make an appointment, the construction team will come to the door to install flush toilets for residents.

This is basically the cost price, and Li Zhi hopes to use the flush toilet to improve the sanitary conditions of Fanjiazhuang, and he does not expect this new thing to earn much money for himself.

In fact, for the residents of Fanjiazhuang, installing a toilet can not only eliminate the stench of the toilet, but also allow the people to have an extra small room at once - in the past, there was a special bathhouse in the small villa in Fanjiazhuang designed by Li Zhi. Nowadays, when the toilet is equipped with a flush toilet, the toilet is not dirty or smelly. People can create a bathing space in the toilet, and the vacant bathing room can be made into a small room.

Spending two taels of silver can not only improve the sanitary conditions, but also free up a small room, which is a very good deal. The original bathhouse could be used for miscellaneous items and as a children's bedroom.

After Li Zhi installed the toilet for Huan Lide, the Huan family immediately got rid of the stench of the toilet and added an extra room. After the people of Sanheng Street, where Huan's house is located, visited the Huan's new toilet, they immediately spread the benefits of it. The people of Fanjiazhuang rushed to Fanjiazhuang's toilet shop one by one to pay money and make an appointment. Within a few days, almost all the people in Fanjiazhuang registered to buy it.

The situation is different for residential houses elsewhere in Tianjin. Most of the houses in Tianjin have not built septic tanks, and to install flush toilets, they need to dig septic tanks temporarily, which is a large amount of work. Without seven or eight taels of silver for civil engineering wages, this flush toilet would not be usable. Therefore, in Tianjin Acropolis and other prefectures and counties, flush toilets have not yet become popular.

But Li Zhi believes that with the exemplary role of the people of Fanjiazhuang, the people of the Ming Dynasty who like to follow the trend of new things, especially the wealthy people, will gradually install flush toilets.

For this kind of flush toilet, Li Zhi is not ready to keep it a secret. This thing is too easy to imitate, unless the entire Ming Dynasty has a patent system to protect Li Zhi's intellectual property rights, Li Zhi can't stop the counterfeiters at all. And Li Zhi's current temperament as a prince of Jinguo is not as good as before. Li Zhi hopes that craftsmen from other places will learn this new type of toilet as soon as possible, and he hopes that the people of Daming will use this kind of flush toilet to improve their living and sanitary conditions.

Zhu Youzhen, the son of heaven, stood in the newly built "bathroom" of the Qianqing Palace, looking at the toilet that Li Zhi paid tribute to in the bathroom, and was amazed.

The toilets in the Qianqing Palace are very large and magnificent.

A few days ago, Li Zhi sent craftsmen from Tianjin to dig a septic tank behind the Qianqing Palace. After the septic tank was dug up, it was sealed with cement by the craftsmen, leaving only a chimney made of white marble slabs for exhaust. In the Qianqing Palace, craftsmen built walls with cement and installed flush toilets to make a toilet.

According to Li Zhi, the toilet with a flush toilet is clean and hygienic, and it should be called a "toilet". Zhu Youzhen guessed that this was the meaning of washing hands after taking out Gong, so he called the toilet a toilet.

Originally, there were no toilets in the Qianqing Palace. The toilet used by the Son of Heaven is called the "official room", which is kept by a special eunuch, and when necessary, it is passed on to the "official room", and it is usually not placed in the palace. Compared with Li Zhi's flush toilet, the original "official room" is unhygienic and inconvenient.

Zhu Youzhen looked at the bathroom in the Qianqing Palace with joy, and said with a smile: "In the future, I won't have to use the embarrassing 'official room' anymore." ”

Zhu Youzhen found a piece of waste paper, crumpled it up and threw it into the toilet. As soon as he pressed the button on the toilet sink, he saw the well water pouring out of the sink into the toilet, wrapping the paper ball and flushing it away.

Zhu Youzhen smiled: "Okay, it's really useful!" With such a bathroom, I don't need to be attended to by others in my private affairs, and the embarrassment is swept away, which is really a good thing. ”

Wang Chengen blinked his eyes and asked, "Holy Lord, how did this Jin Guogong invent so many new things?" Where did he learn it? is the reincarnation of Lu Ban, and I am afraid that it is not as skilled as the skilled craftsmen of Jin Guogong. ”

Zhu Youzhen stroked his beard and said, "I don't know why Jin Guogong was able to invent so many new things. But I know that the Duke of Jin is loyal. Flush toilets are such good things, clean and hygienic, Li Zhi was the first to think of installing them for me, and his loyalty can be seen. ”

Wang Chengen arched his hand and said, "The emperor is shengming." ”

Zhu Youjian stroked his beard and said: "Let the craftsmen of the Duke of Jin not leave, I will not be polite to the Duke of Jinguo, and let him install toilets in the palaces of the prince, King Ding, King Yong and King Mourning." There are also two princesses, who have to install toilets! ”
