A bathroom drainage collection system

Abstract

The present invention provides a toilet drainage collection system, which includes a drainage pipe assembly, a horizontal pipe drainage assembly connected with the drainage pipe assembly, and a water seal assembly connected with the horizontal pipe drainage assembly; wherein, the drainage pipe assembly includes the first A water inlet pipe, a second water inlet pipe, a first vertical pipe and a second vertical pipe; the first water inlet pipe is connected to the second water inlet pipe and internally communicated, and the inner edge of the second water inlet pipe is connected to the inner edge of the first water inlet pipe The edges are tangent; the first water inlet pipe is connected to the first vertical pipe and internally communicated; the connection between the second water inlet pipe and the first water inlet pipe is an enlarged pipe wall cavity. The invention increases the radius of curvature of the wall-attached swirling flow of sewage in the drain pipe assembly by arranging an enlarged pipe wall cavity on the drain pipe assembly, so as to ensure that the sewage can adhere to the wall and swirl.

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] In the prior art, a plurality of 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 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 small curvature radius, resulting in loud drainage sound and easy overflow of odor. [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 m...

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, which is cumbersome to construct, and the space occupied by the sewage pipes is large, and the floor needs to be lowered.

Moreover, the curvature radius 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 due to the 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
