Heated Airflow Humidifier for Fine Mist Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic humidifiers face issues with mist particles sinking due to large particle diameter, leading to unsanitary conditions and temperature drops in indoor spaces, as the mist does not effectively distribute over long distances and tends to condense around the humidifier, promoting mold and bacteria growth.
Innovation Solution
Incorporating a flow path heater within the blower flow path to heat the ascending air stream, which evaporates the mist, reducing particle size and allowing for uniform distribution across the indoor space, while a diversion guide and annular design facilitate the mist's upward trajectory and prevent condensation around the humidifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ultrasonic oscillating elements are used to produce mist, then humidification is achieved, but mist particles sink down due to large particle diameter
Solution Approach 1:
The patent changes the physical parameters of the mist by heating it. The flow path heater increases the temperature of the mist particles, which reduces their density and increases their buoyancy, allowing them to be distributed over longer distances without sinking due to gravity
Solution Approach 2:
The patent introduces an intermediary element (flow path heater) between the mist generation and discharge processes. This heater acts as a mediator that modifies the mist properties by heating it, enabling the mist to overcome gravitational settling and achieve broader distribution
2Use of energy by moving object
If mist is discharged without heating, then energy consumption is reduced, but temperature in indoor space decreases
Solution Approach 1:
The patent applies parameter changes by heating the mist in the flow path, which transforms the thermal state of the discharged air. This heated mist compensates for the cooling effect of evaporation and maintains or increases the indoor space temperature during humidification operation
3Use of energy by moving object
If unheated water is used for humidification, then energy consumption is reduced, but mist particle size remains large
Solution Approach 1:
The patent applies parameter changes by heating the mist after generation but before discharge. This thermal parameter change reduces the mist particle size and improves atomization, achieving fine mist distribution without requiring high-energy ultrasonic vibration or pre-heating of the water
