Description

A toilet water-saving siphon

technical field

The utility model relates to the technical field of toilet water saving, in particular to a sewage discharge pipe arranged under the toilet, the upper end of which is connected to the outlet of the sewage discharge diversion pipe of the toilet, which is used to improve the siphon force of the toilet sewage discharge diversion pipe Toilet water-saving siphon.

Background technique

At present, the toilet sewage system adopts PVC or cast iron pipes with an inner diameter of 100mm to connect the toilet interface to realize sewage discharge. Due to the limitations of the structure of the toilet itself, it is difficult to exert the drainage siphon function, because the current drainage diversion pipe of the toilet is an S-shaped bending structure with an inner diameter of 65mm, and the liquid level difference between the overflow port and the discharge port is generally about 150-180mm, while The pipe section that actually conforms to the siphon principle is usually less than 100mm, and the existing sewage pipe with an inner diameter of 100mm has no siphon effect due to the large difference between its inner diameter and the outlet inner diameter of the sewage diversion pipe of the toilet (more than twice as large), so the existing technology The sewage of modern toilets basically depends on the pressure difference of water to realize excretion, resulting in the need for a large amount of sufficient water to flush, so the water consumption is relatively large. According to fluid mechanics:

Q=[(π/4)d^2 √(1+λL/d+ζ)] √(2gH)

In the formula: Q--flow rate (m^3/s), π--circumference ratio; d--pipe inner diameter (m), L--pipe length (m), g--gravitational acceleration (m/s^2) , H--the water level difference at both ends of the pipeline (m), λ--the resistance coefficient along the pipeline (no unit), ζ--the local resistance coefficient of the pipeline.

It can be seen from the above formula that the flow rate Q is related to the water level difference at both ends of the pipeline. The greater the liquid level difference between the outlet and the liquid surface, the greater the siphon force, and vice versa. Therefore, it is beneficial to increase the water level difference at both ends of the pipeline. Increase the siphon force and improve the sewage discharge effect, so as to save water. However, in actual use, too long pipes are likely to cause poor drainage, which not only does not achieve the effect of rapid sewage discharge, but also easily causes blockage; The obvious exhaust noise affects the use effect of the toilet. The publication date is December 17, 2008, and the Chinese patent document with the publication number CN201165700Y discloses a device for saving water in a siphonic toilet, including an upper connecting pipe, a lower connecting pipe fitted with the upper connecting pipe, and an upper connecting pipe. Take over the soft rubber pad in the annular groove at the upper end of the pipe. After the device is installed in conjunction with the siphon toilet, its drain outlet and the sewage riser, the volume of the newly formed siphon pipe becomes smaller, the initial air volume in the pipe is small, and it is difficult to enter the air during siphon, which improves the siphon performance of the toilet, but the device The lower end of the siphon tube is located in the original water seal of the sewage pipe elbow, and its outlet is closed by the water seal of the sewage pipe, which greatly increases the resistance of air discharge in the siphon pipe at the initial stage of sewage discharge, and cannot achieve the effect of rapid sewage flushing and water saving. On the other hand, the elbow at the lower end of the siphon of the device also increases the sewage discharge resistance and affects the sewage discharge effect. The publication date is November 8th, 1995, and the Chinese patent document with the publication number CN1111315A discloses a kind of improved toilet siphon, which includes a plugging device and a specially designed leather tube. Two operations must be implemented simultaneously. The leather tube is contained in the water outlet of the flush toilet, and the second is to block the flow hole of the discharge bend of the flush toilet where stagnant water enters, forming a powerful siphon when flushing, thereby cleaning the bedpan and its dirt with the minimum amount of water. But the siphon leather tube of this device is too long, it is easy to cause poor drainage, not only can not achieve the effect of rapid sewage discharge, but also may cause blockage; at the same time, it will also cause sewage discharge noise, which affects the use effect of the toilet; at the same time, the device needs to block the stagnant water Entering the injection hole of the discharge bend of the flush toilet is difficult to realize in actual use.
