Energy-saving toilet with three-dimensional large-radian drainage elbow pipe
The invention discloses an energy-saving toilet with a three-dimensional large-radian drainage elbow pipe replacing an S-shaped sewer pipe of an existing toilet. The radian and radius of the three-dimensional elbow pipe are multiplied to greatly reduce excrement flowing resistance. A toilet body and the three-dimensional elbow pipe are in a straight-through connection manner with an inlet facing downwards, so that resistance of a joint between the toilet body and the three-dimensional elbow pipe is greatly reduced. An inlet section of the three-dimensional elbow pipe is designed to be a smallest-diameter section of the whole three-dimensional elbow pipe to make the position of a prone-to-blockage section of the toilet to be clearly visible, so that dredging is facilitated. An annular jet flow passage which consists of an annular jet flow jet orifice and an annular pressure accumulation chamber is designed at a variable-diameter portion of the sewer pipe, the pressure accumulation chamber is connected to a cistern through an internal pipeline, a downward flushing force applied to excrements can be generated by rushing water flow jetted from the annular jet flow passage during flushing, and a thin water film layer is formed between the excrements and the wall of the three-dimensional elbow pipe, so that resistance between the excrements and the wall of the three-dimensional elbow pipe can be reduced effectively.
