Sanitary science: the evolutionary history of the toilet

The toilet is now a necessity for people's daily life. You can't live without it every day. Maybe you are using it now! But in addition to knowing that the toilet makes the street "clean", we avoid having to dig holes to deal with "human waste." In addition to the trouble, how much do we have left with the knowledge of the toilet?

"Dark Age" without a toilet

Since humans have appeared on Earth, everyone is looking for the most comfortable way to cope with their "physiological needs." Take a look at the text that was deleted in the following section:

"On the seventh day of God's creation of the world, he wanted to make sure that mankind could have a permanent rest before he rested. So he made a bush. When God made it, Adam couldn't wait to run to the leaves. Behind Mao’s 'Sanctuary' to solve the urgency."

Of course, Adam will soon find the drawbacks of this early design, especially when the local surface is too hard to dig holes, or when there are no shovel at hand. According to my personal experience, I know that nothing is worse than this kind of thing. It is to solve the urgency after running to the bushes during camping, but stepping on the "product" that I made a few days ago. As a result, people began to hope to find a perfect place to deal with "human waste."

According to archaeological records, as early as 4,000 years ago in the Indus Valley, people began to use the toilet widely. But later, the complicated set of sewage treatment drawings was lost. The construction of sewer facilities has been seriously regressed in the Middle Ages. Perhaps only the people who experienced it in the past know the true meaning behind the play of the Dark Ages. I can imagine that when you were hanging out on the street, the tops and tights suddenly splashed on someone's earlier dirt, and nothing was more disappointing.

Of course, you can't blame this kind of original treatment. Who wouldn't want to have a porcelain toilet under the bed, save the cold and sprint to the outside to solve the problem in the middle of the night. Fortunately, people also realize that it is very vulgar to be able to pour dirt directly out of the window, in addition to being disgusting. It’s been a few centuries before the toilet was returned to people’s lives.

Who invented the toilet?

As early as the early 19th century, the bottom residents still used buckets to solve the urgency. In our imagination, this kind of latrine must be quite delicate, at least in the wooden shed, away from the bedroom, and shared with many families. But in fact, the bucket is just a wooden seat cushion added to the bucket to increase comfort, which is a little more advanced than the potty under the bed. As far as hygiene is concerned, there is still a long way to go to the flushing pipe.

After a while, the toilet was once again on the stage. When it comes to the invention of the flush toilet, we always mistakenly attribute it to the British plumber Thomas Clapp, and in fact, the invention he originally envisaged has nothing to do with the toilet. The toilet has already appeared before him, and Thomas just improved it and made it easier for people to use. His predecessor, John Harrington, was the hero who made the toilet go back to the historical stage. Perhaps this is the true etymology of the word "john" (American slang, referring to the bathroom, toilet).

In 1596, John Harrington designed a flush toilet for Elizabeth I, but it is said that Her Majesty refused to use it. During the next 200 years, the toilets were constantly improved and adjusted until the end of the 19th century, when the most unimportant but most important invention was universally applied. Pedestrians don't have to worry about the terrible splashes that will stain the clothes.

Weird designer's genius design

Although today's washrooms have been beautifully decorated, this does not mean that the development of the toilet has stagnated. In fact, people are constantly improving, perfecting and decorating it. Therefore, in the face of the many functions of the toilet, we can freely choose. Yes, they can meet people's needs. We have a water-saving toilet, like the kind of rumbling sound, it has another well-known name - Duoset, you can choose the flushing method you like. In addition, there are lever, button, pressure and other toilets... We also designed a toilet in a zero-gravity environment for some people who are adventurous.

Other design types are not yet popular, but you can always find clues in the inventor's home. For example, the German designer's "inverted potty" is equipped with a "seat" for people to appreciate their "masterpieces." East and West have been arguing about a question: Should the toilet be “sitting or squatting?” In this regard, British Indians have been trying to cater to the needs of both parties, providing toilets that can sit and squat, however, they design The product has never been sold. This is not surprising. Who would like to sit on a toilet that someone else has stepped on? Similarly, if you climb the toilet and try to solve the urgency, there is a danger of falling into the potty.

Some quirky designers offer a third way for women to be convenient – ​​standing. Nowadays, when hiking in the outskirts of the forest, if you are in a hurry, the ladies can also hold the “shewee (a urinary funnel designed for women)” and stand as easy as a man. Of course, this will be more attractive than you are after the jungle, but it has at least one advantage, that is, you don't have to endure the inconvenience of taking off your pants in cold weather.

Now the toilet function is powerful compared to the iphone phone.

The evolution of the toilet also brought us to Japan. Japan's craft toilet completely frees you from any inconvenience in the bathroom. It is equipped with a wash basin and hand dryer, deodorizing facilities, automatic potty lift button, and imitation sound recording, so you don't need to open the tap to cover it. The embarrassing sound of the toilet.

But technology doesn't necessarily guarantee that nothing can be done. Before you press the button, you must be familiar with the operation of "robo-bog" (a Japanese toilet name). I mistakenly pressed the button labeled "Bidet" as a flush button. As a result, I buried my ignorance: the face was immediately covered with splashed toilet dirt. However, I don't think I will be the first one, nor the last one to encounter a similar situation.

The current toilet is powerful and comparable to the iPhone, making it difficult for people to imagine how the toilet will develop in the future.
