Shower Drying Airflow Layout for Mold and Humidity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower systems fail to effectively dry shower areas, leading to mold, mildew, and residue buildup on walls and curtains, which increases humidity and creates maintenance challenges.
Innovation Solution
A shower drying system using two blowers, one directing heated air downward through louvers or nozzles to push water towards the drain and evaporate it into vapor, while the second blower exhausts the vapor from above the enclosure, reducing humidity and mold growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heated air is directed at the occupant to warm them, then the person is warmed, but water on the walls evaporates faster leaving residue deposits
Solution Approach 1:
The system divides the air treatment function into two separate blowers: one for heating/warming the person, and another for exhausting moisture and vapor. This segmentation allows independent control of warming and drying functions, preventing residue buildup while maintaining person comfort.
Solution Approach 2:
The system extracts and removes the harmful byproduct (water vapor and moisture) from the shower environment using a dedicated exhaust blower. By actively removing the evaporated water before it can leave residue deposits, the system solves the contradiction between warming and preventing residue buildup.
2Productivity
If heated air increases water evaporation rate on walls, then drying speed increases, but humidity increases in other bathroom areas
Solution Approach 1:
The exhaust blower acts as an intermediary that captures and removes water vapor at its source (above the shower enclosure). This prevents the vapor from dispersing into the broader bathroom environment, thus maintaining high drying speed without increasing overall bathroom humidity.
Solution Approach 2:
The system extracts water vapor from the shower enclosure using the second blower positioned above the enclosure. By actively removing the evaporated moisture through dedicated exhaust pathways, the system achieves rapid wall drying while preventing humidity accumulation in other bathroom areas.
3Object-affected harmful factors
If water accumulates on shower walls, then mold and mildew growth increases, but rapid evaporation may increase residue buildup
Solution Approach 1:
The system maintains continuous control over the shower environment by operating blowers that continuously remove moisture and vapor. This continuous action prevents both mold growth (by keeping surfaces dry) and residue buildup (by removing vapor before condensation and drying occur).
Solution Approach 2:
The exhaust blower serves as an intermediary that removes water vapor from the shower enclosure, preventing it from condensing and leaving residue deposits. This intermediary function simultaneously prevents mold growth by maintaining low humidity levels without causing the rapid evaporation that leads to residue buildup.
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
The system efficiently dries shower surfaces, reduces mold and mildew, and minimizes humidity increases in other areas, improving cleanliness and reducing maintenance needs.
Implementation Method 1
The first blower forces air downward into the shower enclosure from a ceiling above through an aiming device (e.g. louvers or nozzles) and onto surfaces of the shower enclosure, pushing water downwardly along the surfaces
Implementation Method 2
Remaining water on the surfaces is evaporated into water vapor that is exhausted from above the shower enclosure
Implementation Method 3
The air also creates water vapor from evaporation of some of the water
Implementation Method 4
The second blower exhausts the air and the water vapor from an area above the shower enclosure
Data Source
AI summary
An application for a shower drying system that directs air downwardly onto the walls, surfaces and/or shower curtain of a shower enclosure. In one embodiment, the air is heated. The movement of the air in the downward direction helps urge droplets of water on the shower surface towards a drain at the lower level of the shower enclosure. Remaining water on the surfaces is evaporated into water vapor that is exhausted from above the shower enclosure, thereby reducing mold and mildew.
