Preferably, the inner wall of the sewage pipe has several protrusions and several recess portions, and the protrusion and recess portion are handed over
For arrangement and transition connects to form a bellows segment.
Preferably, the difference in height between the peaks and troughs of the bellows segment is not less than 1.5mm.
Preferably, between two adjacent peaks of the bellows segment distance range in 35mm-45mm.
Preferably, the sewage pipe include along drainage direction successively arc transition connection into dirty section, changeover portion and blowdown
Section.
Preferably, described to extend obliquely upward into dirty section along the rear of the closestool, the end into dirty section turns to connection
The starting point of the changeover portion, the changeover portion extend obliquely along the front of the closestool, and the blowdown section is along the closestool
Front horizontal extend.
Preferably, at least described inner wall into dirty section has the protrusion and/or recess portion.
Preferably, the sewage pipe is a siphon piping that can form siphon.
Preferably, the sewage pipe is integrally formed in the toilet seat body.
The beneficial effects of the utility model are:
A kind of toilet bowl sewage draining pipe of the utility model, blowdown tube inlet are connected with closestool urinal bottom, the sewage pipe
Outlet is connected with extraneous sewage pipe, the inner wall of the sewage pipe at least a protrusion and/or recess portion, protrusion and recess portion
The contact area reduced between blow-off line inner wall and MISO medium is set, to reduce frictional force between the two, is easier to
MISO medium is washed away in current scour power, toilet tube is not easy to plug.
Detailed description of the invention
Attached drawing described herein is used to provide a further understanding of the present invention, and constitutes one of the utility model
Point, the exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the utility model
Improper restriction.In the accompanying drawings:
Fig. 1 is prior-art illustration;
Fig. 2 is a kind of cross-sectional view of toilet bowl sewage draining pipe of the utility model;
Fig. 3 is the enlarged drawing in Fig. 2 at A;
Fig. 4 passes through cross-sectional view when sewage pipe for MISO medium under a kind of toilet bowl sewage draining pipe scouring state of the utility model.
Specific embodiment
In order to be clearer and more clear technical problem to be solved in the utility model, technical solution and beneficial effect, with
Under in conjunction with the accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein
Example is applied only to explain the utility model, is not used to limit the utility model.
As shown in Figures 2 to 4, a kind of toilet bowl sewage draining pipe, 1 entrance of sewage pipe are connected with closestool urinal bottom 2, the row
The dirty outlet of pipe 1 is connected with extraneous sewage pipe (not shown), and 1 inner wall of sewage pipe has at least a protrusion and/or recess portion,
Specifically, protrusion is to be outwardly protruded to be formed by 1 inner wall of sewage pipe, recess portion is to be inwardly recessed to be formed by 1 inner wall of sewage pipe, this
In embodiment, sewage pipe 1 is a siphon piping that can form siphon, and sewage pipe 1 is integrally formed in the toilet seat body.
In the present embodiment, the inner wall of the sewage pipe 1 has several protrusions and several recess portions, the protrusion and recessed
Portion is alternately arranged and transition connects to form a bellows segment R, that is, protrusion forms the wave crest R1 of bellows segment R, recess portion forms bellows segment
The trough R2 of R;In the present embodiment, the difference in height between the wave crest R1 and trough R2 of the bellows segment R is not less than 1.5mm;This reality
It applies in example, bellows segment R is the wave-like of rule, distance (i.e. period) range between the two adjacent peaks R1 of the bellows segment R
In 35mm-45mm, the contact area between 1 inner wall of sewage pipe and MISO medium 3 can be greatly reduced by the way that bellows segment is arranged, thus
Reduce frictional force between the two, it is easier to which the siphon power of water flow siphons away MISO medium 3, and toilet tube is not easy to plug.
Certain the present embodiment can also use, and protrusion connects to form irregular wave-like with recess portion transition, either,
The recess portion that the present embodiment is inwardly recessed only with formation, then either, only with the protrusion for forming outwardly convex, concrete form is not
It is restricted, as long as final realize the contact area for reducing sewage pipe 1 inner wall and MISO.
In the present embodiment, the sewage pipe 1 include along drainage direction successively arc transition connection into dirty section 11, changeover portion
12 and blowdown section 13.Described to extend obliquely upward into dirty section 11 along the rear of the closestool, the end into dirty section 11, which turns to, to be connected
The starting point of the changeover portion 12 is connect, the changeover portion 12 extends obliquely along the front of the closestool, 13 edge of blowdown section
The front horizontal of the closestool extends.
In the present embodiment, at least described inner wall into dirty section 11 has the protrusion and/or recess portion, can also use
On into any the two of dirty section 11, changeover portion 12 and blowdown section 13 or whole threes are equipped with the protrusion and/or recess portion.
The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new
