Description

U-shaped sewage discharge structure of a toilet

technical field

The utility model relates to the technical field of bathroom products, in particular to a U-shaped sewage discharge structure of a toilet.

Background technique

Toilets are divided into four categories according to the daily use methods: toilets, squatting toilets, urinals and bidets. As we all know, the current technology of toilets in the world comes from 1775 AD in the 18th century. The product technology has been developed until now, and the structure of the technology has always maintained the "horizontal" "surface" sewage technology. The length of the sewage pipe on the ground is 600-1000 mm, so the traditional toilet looks like a "top chair" with a backrest, while squatting toilets, urinals and bidets all have the same technical structure, and it is very difficult to shape them into various artistic shapes or individual shapes. With the progress of society, today in the 21st century AD 2017, the bathroom civilization has been developed for more than 200 years. It has always been the same technology and the same shape. People have the choice and application of "eye fatigue". In the modern society where culture has been rapidly improved, especially young people are open-minded. They like exaggerated artistic shapes or their favorite "graffiti" and other personalized art to satisfy their spiritual needs. Artists even found another way to make toilets into various styles such as antique, cartoon, European, animal, etc. However, because the drainage technology is a horizontal "surface" strip, it is difficult for artists to break through.

According to statistics, in the daily life of residents, flushing water for toilets accounts for 40%-50% of the total daily water consumption of residents. The water resources in the city have constituted the most important part of wasting water resources in cities. In addition to the continuous shortage of water resources and the increasing severity of water waste, water saving has become particularly important. Therefore, the development of water-saving toilets is also the general trend. For this reason, the applicant has carried out a large number of researches and tests, and has developed water-saving high-pressure siphon squatting toilets and toilets such as back drainage siphon toilets. Praise, the product is highly efficient, water-saving, clean and safe, and has been widely promoted and popularized. The squatting toilet with a water consumption of 9-12 liters is reduced to less than 3 liters, and the water tank is filled with 6 liters of water. Usually only use Small buttons will suffice. However, he only changed the flush-down technical toilet and other toilets since the 18th century, transformed the flush-down type into a siphon scrubbing technology, and transformed the traditional small-pipe siphon technology toilet and other toilets into an internationally accepted 4-inch siphonic toilet. , although it achieves obvious water-saving, clean, and safe practical effects, which makes the toilet civilization around the world take a step forward, but the long strip sewage structure of the horizontal "surface" has not changed. There are also issues such as "splashing ass", although improvements have been made, it is still not satisfactory.
