Toilet drainage collection system

Abstract

The invention provides a toilet drainage collection system. The toilet drainage collection system comprises a drainage pipe assembly, a transverse pipe drainage assembly communicating with the drainage pipe assembly and a water seal assembly communicating with the transverse pipe drainage assembly, wherein the drainage pipe assembly comprises a first water inlet pipe, a second water inlet pipe, afirst vertical pipe and a second vertical pipe, the first water inlet pipe and the second water inlet pipe are connected, the interior of the first water inlet pipe communicates with the interior of the second water inlet pipe, the inner edge of the second water inlet pipe is tangent to the inner edge of the first water inlet pipe, the first water inlet pipe is connected with the first vertical pipe, the interior of the first water inlet pipe communicates with the interior of the first vertical pipe, and a pipe wall cavity with an expanded volume is arranged at the communication part between the second water inlet pipe and the first water inlet pipe. According to the toilet drainage collection system, due to the fact that the pipe wall cavity with the expanded volume is arranged in the drainage pipe assembly, the curvature radius of wall-attached rotational flow of sewage of the drainage pipe assembly is increased, and it is guaranteed that the wall-attached rotational flow of the sewage can be achieved.

Description

technical field [0001] The invention relates to the field of building drainage systems, in particular to a toilet drainage collection system. Background technique [0002] The drainage and collection system of the prior art toilet adopts a plurality of sewage pipes, the construction is loaded down with trivial details, the space occupied by the sewage pipes is large, and the floor needs to be lowered. Moreover, the radius of curvature of the drainage pipe assembly of the bathroom drainage collection system is too small. When the sewage discharge volume is large, it is often impossible to swirl against the wall because of the too small radius of curvature, resulting in loud drainage sounds and easy overflow of odors. [0003] In addition, the existing horizontal pipe drainage pipes are often laid in the building wall and provided with inspection ports. When the pipes or water seals are blocked, the operator needs to open a special inspection port for inspection in the wall. ...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, multiple sewage pipes are used in the drainage collection system of the toilet, and the construction is cumbersome, and the space occupied by the sewage pipes is large, and the floor needs to be lowered.

Moreover, the curvature radius of the drainpipe assembly of the bathroom drainage collection system is too small. When the sewage discharge volume is large, it is often impossible to swirl against the wall because of the too small curvature radius, resulting in loud drainage noise and easy overflow of odors.

[0003] In addition, the existing horizontal pipe drainage pipes are often laid in the building wall and provided with inspection ports. When the pipes or water seals are blocked, the operator needs to open a special inspection port for inspection in the wall. Obstacles, poor inspection vision and small inspection space for operators during inspection, and inconvenient or even impossible inspection of horizontal pipe drainage pipes

Moreover, the drainage structure of the prior art is complex, the manufacturing process is cumbersome, and the production cost is high, which is particularly unfavorable for mass production
