Water-Vapor Separation Box for Instant-Hot Dispensers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-vapor separation structures for instant-hot type water dispensers have complex pipe connections that are prone to leakage, leading to unsatisfactory design and performance.
Innovation Solution
A water-vapor separation box design featuring a box body with a water input tube, first and second block plates, and separate vapor and water output tubes, where the vapor output tube is positioned higher than the water output tube, eliminating the need for a vapor exhaust pipe and allowing for direct vapor output, and incorporating room temperature and hot water input tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vapor exhaust pipe is provided to exhaust or recover vapor, then vapor can be processed and transported, but the pipe connection becomes complicated and leakage-prone
Solution Approach 1:
The patent extracts the vapor exhaust function from the water output system by providing a separate vapor output tube that directly outputs vapor from the vapor separation chamber. This eliminates the need for complex vapor exhaust pipes and connections, while maintaining effective vapor exhaust capability. The vapor output tube is positioned higher than the water output tube to enable direct vapor discharge without interfering with water flow.
2Ease of operation
If hot water is fetched first then room temperature water, then hot water is available, but water overheating problem occurs
Solution Approach 1:
The patent segments the water input into separate room temperature water input tube and hot water input tube, and segments the output into separate water output tube and vapor output tube. This segmentation allows independent control of hot water and room temperature water flows, preventing the overheating problem that occurs when hot water is fetched first followed by room temperature water. Each tube can be controlled independently to achieve desired water temperature.
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
Simplifies the pipe structure, prevents water overheating by separating vapor and water outputs, and enhances the separation efficiency of room temperature and hot water.
Implementation Method 1
the vapor output tube is disposed around an outer perimeter of the water output tube to output vapor, and is separate from the water output tube, with a vapor input elevation of the vapor output tube higher than a water input elevation of the water output tube

AI summary
A water-vapor separation box for an instant-hot type water dispenser comprises: a box body, including: a water input tube, disposed on a side wall at an upper end of the box body; a first block plate, disposed on a rear side of a water output end of the water input tube; a second block plate, disposed at a rear side of the first block plate, to make the vapor flow upward; a water output tube, disposed at a rear side of the first block plate to directly flow the water out; a vapor output tube, disposed around outer perimeter of the water output tube, with vapor input elevation of the vapor output tube higher than the water input elevation of the water output tube; and a box cover, disposed over an upper opening of the box body.
