Flush Toilet Vortex Flow Guide for Complete Filth Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flush toilets face challenges in effectively discharging suspended sewage due to water convergence issues, leading to incomplete flushing and noise problems during operation.
Innovation Solution
The design incorporates a basin portion with a filth receiving surface, a sewage pipe, and a washing water supply system featuring flow guide portions that create a vortex to agitate and discharge filth, along with a throttling mechanism to reduce noise by decelerating water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water-flushing is used to discharge sewage, then the flushing action is simple, but the suspended filth cannot be completely discharged and tends to roll up and down in the filth receiving portion
Solution Approach 1:
The patent applies mechanical vibration by creating a vortex flow through the water guide ring and flow guide portions. The vortex generates rotational motion that agitates and lifts suspended filth from the filth receiving portion, preventing it from rolling back and ensuring complete discharge. This transforms the simple linear water flush into a rotational flushing action that effectively removes suspended contaminants.
Solution Approach 2:
The patent utilizes hydraulic principles by designing a water guide ring and flow guide portions that direct water flow to create a vortex. The water flow pattern is engineered to generate rotational hydraulic force that acts on the suspended filth, lifting and transporting it through the sewage pipe rather than allowing it to settle or roll in the filth receiving portion.
2Power
If a large amount of water instantly converges at the water outlet, then the flushing power is strong, but abnormal noise is produced when water collides with air
Solution Approach 1:
The patent applies preliminary action by using the water guide ring and flow guide portions to pre-direct and shape the water flow before it reaches the outlet. The water is guided to flow smoothly along the filth receiving surface and into the vortex, preventing sudden convergence and air collision. This preliminary flow conditioning maintains flushing power while eliminating the abnormal noise caused by turbulent water-air interaction.
3Area of stationary object
If a large amount of water falls on the ceramic wall or water-sealing surface, then the flushing coverage is extensive, but large noise is produced and affects others
Solution Approach 1:
The patent applies local quality by using the water guide ring and flow guide portions to distribute water flow in a controlled manner across different areas of the filth receiving surface. Instead of allowing water to fall freely and create noise, the flow is guided along specific paths, creating localized flushing zones that collectively cover the entire surface. This directed flow approach maintains extensive coverage while minimizing noise by preventing water from falling directly onto hard surfaces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances flushing capacity, reduces noise, and ensures complete discharge of suspended filth by generating a vortex and optimizing water flow, while avoiding dead spaces and swirling issues.
Implementation Method 1
The first water flow and the second water flow act together to generate a vortex to agitate the filth and discharge the filth from the sewage pipe
Implementation Method 2
a second flow guide portion is formed at a rear portion of the filth receiving surface, the washing water flows out along an inner peripheral surface of the inner edge portion from the water outlet to the rear portion of the filth receiving surface, and is guided by the second flow guide portion to rotate along a peripheral wall of the recess

AI summary
A flush toilet, comprising a washing water supply portion which has a water outlet and a water inlet configured to connect to an external water supply pipe, is disclosed. Water flowing in from the water inlet flows from a first water inlet pipe to a second water inlet pipe, and then flows from the second water inlet pipe to the water outlet, a flow sectional area of the first water inlet pipe is smaller than a flow sectional area of the water inlet, and a flow sectional area of the second water inlet pipe is larger than the flow sectional area of the first water inlet pipe.
