The wash down closet has changed the dirty and messy phenomenon of traditional toilets, and also brought us a lot of convenience. So, do you know how wash down closet works?

What is the working principle of wash down closet? Under the wash down closet, there is an invisible, inverted U-shaped elbow, which acts as a "water stopper", so there is always a small amount of clean water that cannot be flushed into the elbow and remains at the bottom of the toilet. , Thereby blocking the odor of the sewer and septic tank from circulating into the room through the toilet.

When the toilet needs to be flushed, a large amount of clean water in the water storage tank will flow into the toilet from the inlet pipe at a very fast speed. The whole process takes about three seconds. The water level in the toilet will rise rapidly, and the water level in the toilet elbow will also Synchronous rise, when the water level in the elbow rises to the top of the pipe, by virtue of its own gravity, the water will expel the air in the elbow, flow down the pipe and fill the pipe, and at this time a siphon phenomenon occurs. The water continuously passes from the highest point and flows out from the elbow. Once the water in the pipe flows quickly, the feces and debris in the toilet can be sucked in and discharged together to complete its cleaning task.

What is siphoning? As early as in ancient China, our ancestors used the principle of siphon to create a variety of peculiar siphons, which were also called "Zhuzi" and "Guoshanlong" at that time. The siphon phenomenon can occur, mainly because the water surface of the nozzle is exposed to different atmospheric pressures and water pressures. The water will flow from the side with high pressure to the side with low pressure. The pressure difference of the water column is used to make the water column flow out along the pipe. The flush toilet can work repeatedly. The feces flushed by the wash down closet will flow into the septic tank, and finally become fertilizer after a series of anaerobic fermentation, effectively reducing environmental pollution.

According to the data provided by the World Toilet Organization, if we go to the toilet on average 6 to 8 times a day, then it is about 2500 times a year. Carefully calculate that we spend more than two years in the toilet in our lifetime. In this way, going to the toilet has also become a major event in life, and wash down closet makes this major event more convenient and civilized.

The small toilet is a big civilization. The invention of the wash down closet not only solves the personal hygiene problem, but also makes a special contribution to the progress of human civilization, the improvement of human living standards and the development of urban construction.
