Flush and siphon toilets

The direct flush toilet uses the momentum of the water to discharge the dirt. Generally, the pool wall is steep and the water storage area is small. In this way, the hydraulic power is concentrated, and the falling hydraulic power around the toilet ring is increased, and the flushing efficiency is high. Using the great thrust formed by the compressed air, the flushing speed is fast, the momentum is strong, the sewage is strong, the speed is fast, the water is less, and there is no leakage. Because the direct flushing type uses the instantaneous powerful kinetic energy of the water flow, the sound of impacting the pipe wall is relatively loud. The rear drainage is mostly straight flush. The diameter of the direct flush toilet sewer pipe is large, and it is easy to wash down larger dirt.

The structure of the siphon toilet is that the drainage pipe is "∽" type. After the drainage pipe is filled with water, there will be a certain water level difference. The suction generated by the flushing water in the sewage pipe in the toilet will discharge the stool. Because the siphon toilet The flushing does not rely on the momentum of the water flow, so the water surface in the pool is relatively large, and the flushing noise is small.
