Spiral toilet blow-off pipe

Abstract

The invention discloses a spiral toilet blow-off pipe. The spiral toilet blow-off pipe comprises an inlet section, an outlet section, an upper spiral section, a lower spiral section, a lowest top wall of the upper spiral section and a highest top wall of the lower spiral section. The inlet section, the outlet section, the upper spiral section and the lower spiral section are designed into an approximately spiral hollow ring; the upper spiral section and the lower spiral section are not in the same plane; and after eddy current is formed through the inlet section and the upper spiral section by using the inertia force of the water flow, the direction of the eddy current is basically consistent with the structure of the pipe, and the force attenuation of the water flow is extremely low, so that dirt can flow out of the lower spiral section very smoothly. In the whole displacement process, the siphon condition is made without a higher water head at the inlet or jet water flow of higher pressure, so that the spiral toilet blow-off pipe has four advantages of water saving, forcible scouring, difficulty in blockage due to large caliber and complement displacement compared with an S-shaped low-off pipe.

Description

Technical field: [0001] The invention relates to a sanitary appliance, in particular to a spiral type toilet sewage discharge pipe which can not only ensure a certain water sealing depth and a super large diameter, but also keep the inertial force of the water flow as much as possible and reduce the sewage discharge resistance. Background technique [0002] Sanitary ware has a history of more than 500 years. It is reasonable to say that the structure should be finalized. It has gone through a long process of exploration during the evolution from the relatively water-consuming in the past to the comparatively water-saving today. [0003] Sanitary ware looks simple, but in fact it is a comprehensive application of very complex fluid mechanics knowledge. A slight change in the flushing structure will directly affect the effect of washing and replacement. In today's era when the world is short of water resources and the world is advocating energy conservation and emission reduc...

Problems solved by technology

[0008] In addition, the current S tube used as water storage and replacement has a great defect in function: due to the limitation of the height of the toilet base, the straight part of the S tube is very short, and the negative pressure formed in the tube is very small when the flow is cut off. The siphon force is very limited, so the pipe diameter must not be too thick

Therefore, it is necessary to save water and make the S pipe thicker, which cannot be realized by the usual S pipe design scheme.
