When did the toilet go out

There is no precise statement about the origin of the flush toilet. One popular theory is that in 1596 the English aristocrat John Harrington invented the first practical toilet – a wooden seat with a cistern and flush valve. Before that, many people always went to the nearest big tree and small river to solve the problem on the spot.

However, this invention was not popularized due to the imperfection of the sewage system. It was only about 300 years later that the British plumber Thomas Kleppa invented an advanced water-saving flushing system, and waste discharge began to enter a modern period. As can be seen from the above, the improvement of the sewage system and the promotion of flush toilets are complementary to each other.

It was not until the sixties and seventies of the 20th century that European and American countries began to use toilets with flush toilets. In the 80s, flush toilets only appeared in luxury hotels in Beijing. Today, 2.9 billion people in developing countries do not have access to a bathroom.

Now, China's toilet area standards and facility standards are officially included in the "2000 well-off urban and rural residential planning and design guidelines". In the city, "double bathroom" has become a trendy type of real estate development.

The word toilet was coined by the ancient Chinese. The toilet bowl used by Chinese folks is a round wooden barrel with a lid, and the inside and outside of the barrel are coated with tung oil or fine waterproof vermilion lacquer. The Western-style toilet we commonly see now has a long history of invention and technological innovation, witnessing the development of modern civilization.

In 1596, the English aristocrat John Harrington invented the toilet, which consisted of a cistern, a flush valve and a wooden seat, which was dedicated to Queen Victoria and is considered the beginning of the modern flush toilet because of its flush valve.

In 1775, the English watchmaker Alexander Cummings improved the toilet's water reservoir so that the toilet automatically closed the valve every time it ran out of water, and it also allowed the water to fill the tank automatically.

In 1778, the British inventor Joseph Bramley improved the flush toilet, inventing a three-ball valve that can control the flow of water in the tank and a U-shaped bend to prevent the smell from escaping the sewage pipe.

The original toilet bowl was made of wood, but the disadvantage was that it was not hard enough to make a fixed shape and easy to leak. And after a long period of use, dirt will remain on the surface, which is easy to breed bacteria. Later, someone used stone and lead to make a toilet, but the steps were troublesome.

In 1827, John Dalton used ceramics for the first time as the cylinder and fittings of a flush toilet.

In 1883, Thomas Turifeld marketed the ceramic toilet, which became the most widely used sanitary appliance and the most common toilet today.

In 1885, Thomas William Tulweford patented the first all-ceramic toilet in England, and dozens of patents for improvements have been granted each year since.

In 1914, the first ceramic toilet in China was manufactured by the British in Tangshan, the Qixin Ceramics Factory (the predecessor of the Tangshan Ceramics Factory).

In the sixties of the 20th century, flush toilets began to prevail in Europe and the United States, and later spread to Japan, South Korea and other Asian countries.

In the early 80s of the last century, it was only seen in a high-end hotel in Beijing, but now it is even used in toilets in Beijing.
