Direct Water Purifier Flushing Valve Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Direct water purifiers face an excessive increase in pump pressure when a hot water heater is instantaneously operated, leading to reduced durability of the product.
Innovation Solution
The direct water purifier includes a flushing valve in a flushing flow path that is open during operation of the heating part, which helps to prevent an excessive increase in pump pressure by allowing concentrated water to be discharged from the second filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a hot water heater is instantaneously operated in a direct water purifier, then hot water can be provided quickly, but pump pressure increases excessively reducing product durability
Solution Approach 1:
A flushing valve is introduced as an intermediary component in the concentrated water discharge path. This valve mediates between the RO membrane (second filter) and the drain, allowing controlled discharge of concentrated water during heating operation to prevent pressure buildup while maintaining the instantaneous hot water delivery capability
Solution Approach 2:
The flushing valve is dynamically controlled to open during heating part operation and close during normal purification. This dynamic adjustment allows the system to adapt its flow characteristics based on operational mode, preventing excessive pump pressure during instantaneous hot water delivery while maintaining normal purification function
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 configuration effectively prevents an excessive increase in pump pressure when the hot water heater is operated, thereby enhancing the durability and performance of the direct water purifier.
Implementation Method 1
a pump disposed in the second flow path to supply water having a predetermined hydraulic pressure or higher to the second filter
Implementation Method 2
a heating part for receiving the water filtered by and supplied from the third filter and heating the same to a predetermined temperature
