On June 14th, the "New Japan Overseas Chinese News" published an article saying that Japan's warm water washing toilet can be called the biggest revolutionary in the toilet field. Some people say that after stepping into the bathroom, the smart toilet lid will automatically open immediately, just like In the welcoming of the general, the heart is inexplicably surging with a sense of joy.
The toilet seat that Chinese people go to Japan to buy is actually a toilet seat with a warm water washing system. The operation panel on the wall or on the side of the toilet can control many functions: for example, heating the toilet seat and adjusting the water during washing. Press, water temperature and angle, etc., play music that covers the sound of the toilet, etc.
But in fact, Japan is the real 'latecomer' and 'curve overtaking' in the toilet field. In the Meiji era, the whole society of Japan began to 'de-Asian', in this movement, the 'toilet' is also learning In the range. When Okura and his relatives went to Europe to study in 1903, they saw a whitewashed toilet. The heart was full of shocks. At that time, the Japanese were still using outdoor toilets that were not even in the sewers. He decided. I want to make the Japanese toilet 'modernized'.
In fact, as early as the 19th century, Japan imported toilets from abroad. At the beginning of the 20th century, ceramics were used to make urinals and squat toilets. However, there was no domestic toilet in Japan. The first domestic toilet appeared in 1914. The big warehouse and pro-experience that was shocked by the toilet in Europe.
Gradually, toilets have gradually spread in Japanese society. In 1964, Japan was once again subjected to a new cultural shock: Switzerland and the United States began to use toilets with warm water washing functions, and Japan once again became a latecomer. Ina ceramics and Toyo pottery can only import new toilets from Switzerland and the United States.
Three years later, Japan has kept pace, and the 'domestic toilet lid' has finally appeared on the market. It can be said that by this stage, Japan has been advancing in the process of 'imitation' of European and American toilets. After 1970, it began to gradually Counterattack.
In 1980, Dongtao Company first released the 'Wei Washi' toilet cover, which was the beginning of the Japanese toilet counterattack. In the development stage of Washlett, 300 practitioners took turns to try, the study is most suitable for washing the anus The temperature of the water. Then, from the perspective of antibacterial, antifouling and comfort, the optimum spray angle for washing is studied. After repeated tests, it is found that the angle of the spray should be set to 43 degrees when the anus is washed, and after the female urinates When washing, the spray angle is set to 53 degrees, in order to minimize the splash of water after washing the anus to the surrounding.
By 1987, an 'excellent toilet' was called Queen of Washley, and its toilet seat was already light and light, the front and rear positions of the spray tube were adjustable, and deodorizing and remote control functions were also included. It is the level of sophistication that many Chinese toilet manufacturers have yet to achieve.
The toilets produced by Japan's largest sanitary equipment manufacturer have become the most efficient and water-saving toilets in the world in the late 1990s. From the study of European and American toilets to the creation of the world's most water-saving toilets, it took decades. Continuous improvement.
Initially, the flushing water needs about 13 liters of water per flush. This is a huge burden of consumption for the family and public facilities. At the same time, it has become a burden on the society with increasingly serious water shortages. After research and improvement, it can save 50% per flush. % of water, only about 6 liters of water.
Although the technicians at the time thought that 6 liters was already the water saving limit, in 2002, the manufacturer invented the cyclone rinsing method, changing the traditional way of flushing from the front, but letting the water flow from both sides of the toilet. The edge of the toilet rushes out at an angle, naturally forming a vortex in the toilet. Finally, only a very small amount of water is needed to flush the toilet. By 2012, only 3.8 liters of water will be needed to flush the toilet.
The manufacturer's requirements for cleaning are not only satisfied with the cleaning of the naked eye, but also for the naked eye. It will also be studied. It is not enough to wash away the waste with the least amount of water. The bacteria inside have also disappeared, so that you can rest assured.
In recent years, Japanese manufacturers have used a special liquid of 'cleaning sterilizing water' to spray in the toilet tank, the surface of the spray pipe, used for sterilization and prevention of dirt accumulation. Cleaning the sterilizing water does not require additional purchase, its The source is tap water. The internal device of the toilet electrolyzes the substances contained in the water to produce a sterilization component. Then, the 'clean sterilization water' is automatically sprayed on the toilet tank and the spray pipe, without any detergent or medicine. To remove 99% of the bacteria, the sterilization effect is equivalent to deodorization.
It is often said that Japan was a 'cottage country' decades ago. Many products and ideas come from Europe and the United States, but few people think that Japanese society is still a 'cottage' country because they are 'taken'. Things are constantly researching and improving, doing the best in terms of detail, getting the world recognized or even surpassing the birthplace. At this point, no one cares whether it is a 'cottage'.
