Flush Water Distributor Guide Surface Throttling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flushing water distributors, such as DE 33 15 926, inadequately distribute flushing water, particularly affecting the siphon's flushing performance and surface rinsing of ceramic sanitary items.
Innovation Solution
A flushing water distributor with a central axis and inner wall, featuring a separating part that divides the flushing water channel into right, left, and middle distribution sections, where the middle section has a guide surface causing a throttling effect to improve siphon flushing and surface rinsing, with the guide surface designed to gently throttle and direct water jets for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flushing water is distributed directly without throttling, then the structure is simple, but the siphon flushing performance is poor
Solution Approach 1:
The distributor is divided into three separate distribution sections (left, middle, right) with the middle section specifically designed for siphon flushing. This segmentation allows targeted optimization of water flow for different functions without complicating the entire structure excessively.
Solution Approach 2:
A guide surface is introduced as an intermediary element in the middle distribution section to throttle and redirect water flow toward the siphon. This intermediary structure enables effective siphon flushing without requiring complex valve mechanisms or additional components.
2Reliability
If water flow is throttled in the middle distribution section, then siphon flushing is improved, but the flow velocity decreases
Solution Approach 1:
Throttling is applied locally only in the middle distribution section where water is directed to the siphon, while the left and right distribution sections maintain higher flow velocities for surface rinsing. This localized application of throttling achieves siphon flushing improvement without compromising overall system performance.
3Adaptability or versatility
If three separate distribution sections are provided, then flushing coverage is improved, but the device complexity increases
Solution Approach 1:
The distributor structure with three distribution sections is designed to serve multiple functions: surface rinsing through left and right sections, and siphon flushing through the middle section. This multi-functional design achieves comprehensive flushing coverage while avoiding the need for separate devices for each function.
4Reliability
If water jets are directed at high angle to siphon, then flushing effectiveness is improved, but turbulence increases
Solution Approach 1:
The guide surface acts as a mediator that gradually redirects water flow from the inlet direction toward the siphon at an optimal angle. This gradual redirection through the guide surface reduces turbulence compared to abrupt directional changes, while still achieving effective siphon flushing.
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
Enhances the flushing performance of the siphon area and surface rinsing by effectively throttling and guiding water jets, particularly beneficial for flushing out light materials like toilet paper, while ensuring thorough cleaning of sanitary ware surfaces.
Implementation Method 1
the guide surface is arranged in the middle distribution section in such a way that the flow in the middle distribution section in the area of the guide surface experiences a throttling effect or can be throttled
