Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 3 to 5, the siphon sewage pipe of the back-row toilet according to an embodiment of the present invention sequentially includes an ascending section 1, a turning section 2, a descending section 3 and a horizontal section 4 along the water flow direction, the horizontal section 4 includes a first horizontal section 41 and a second horizontal section 42 along the water flow direction, the first horizontal section 41 is located between the descending section 3 and the second horizontal section 42, and the pipe diameter of the first horizontal section 41 is smaller than the pipe diameter of the second horizontal section 42. Therefore, the pipe diameter of the first transverse section 41 is reduced, so that the position where the pipe diameter is increased is moved backwards, the air in the pipe is more favorably discharged, the negative pressure can be formed by the sewage discharge pipeline more quickly, the absolute value of the formed negative pressure is larger, and the flushing effect of the toilet can be effectively improved.
In this embodiment, the top wall of the first transverse section 41 is lower than the top wall of the second transverse section 42, and the top wall of the first transverse section 41 is connected with the top wall of the second transverse section 42 through a longitudinal first connecting wall 43. Furthermore, the rear wall of the descending section 3, the top wall of the first transverse section 41 and the first connecting wall 43 form a concave recess 5. Specifically, the recess 5 has a U-shaped structure, the front wall (i.e., the lower portion of the rear wall of the descending section 3) and the rear wall (i.e., the first connecting wall 43) of the recess 5 are vertical walls, and the bottom wall (i.e., a portion of the top wall of the first transverse section 41) of the recess 5 is a horizontal wall. In other embodiments, the recess 5 may also be of a U-like configuration.
In the present embodiment, as shown in fig. 3, the length H of the bottom wall of the recess 5 is preferably greater than 25m, and more preferably 30mm.
In this embodiment, the bottom wall of the first transverse section 41 and the bottom wall of the second transverse section 42 are horizontally connected, and the position of the axis of the second transverse section 42 is higher than the position of the axis of the first transverse section 41.
In this embodiment, the pipe diameters of the ascending section 1, the turning section 2, the descending section 3 and the first transverse section 41 are substantially the same.
In this embodiment, the bottom of the toilet bowl 10 of the toilet is provided with an injection hole 11, and when the injection hole 11 injects pressure water flow towards the inlet of the rising section 1, the siphon sewage pipeline is prompted to form siphon. The injection hole 11 may be in communication with tap water or with an outlet of a water pump or with a drain port of a higher positioned water tank, wherein the higher positioned water tank has a higher gravitational potential energy of water, thereby also being able to provide pressurized water to the injection hole 11.
Fig. 5 is a graph showing the comparison between the effects of the flushing experiment of the back-row toilet of the present embodiment and the back-row toilet of fig. 1 in the prior art, in which the solid line in the graph shows the variation trend of the negative pressure value in the siphon sewage pipeline of the present embodiment along with the lapse of the flushing time, and the dotted line shows the variation trend of the negative pressure value in the siphon sewage pipeline of the back-row toilet of fig. 1 along with the lapse of the flushing time in the prior art. As can be seen from FIG. 5, the present embodiment has a maximum negative pressure between 3.1 seconds and 3.2 seconds after the start of flushing, where the absolute value of the negative pressure is greater than 800Pa, whereas the prior art rear row toilet of FIG. 1 has a maximum negative pressure between 3.5 seconds and 3.6 seconds after the start of flushing, where the absolute value of the negative pressure is only about 400 Pa. It can be seen that this embodiment can reach the maximum negative pressure more quickly than the siphon sewage pipe of fig. 1 in the prior art, thereby promoting the siphon to be formed more quickly, and the maximum negative pressure of the former is about twice as high as that of the latter, which improves the flushing effect.
