Humidifying Filter Layout for Cleaner Air Conditioner Humidification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners cannot effectively increase air humidity, even when the air is dry, and often risk contaminating humidifying filters due to improper water management and submersion.
Innovation Solution
An air conditioner design featuring a humidifying filter installed at a height above the water tray to prevent submersion, with a rotator-controlled humidifying gear that stops water supply when not needed, allowing dry air to dry the filter, and a separable humidifying gear module for easy replacement, including a drain hole to prevent water contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the humidifying filter is installed close to the water tray to improve humidification efficiency, then the humidification effect is enhanced, but the filter is at risk of being submerged under humidifying water which causes bacterial contamination
Solution Approach 1:
The humidifying filter is positioned at a height above the water tray level, transitioning from a horizontal proximity arrangement to a vertical spatial separation. This dimensional change allows the filter to receive water droplets from above through the spray nozzle while avoiding direct submersion in the water tray, thus preventing bacterial contamination while maintaining humidification efficiency.
2Productivity
If the humidifying gear continuously supplies water to the humidifying filter, then humidification performance is improved, but the filter cannot be dried by circulated air which promotes bacterial growth
Solution Approach 1:
The humidifying gear operates periodically rather than continuously. The control unit activates the humidifying gear only when humidification is needed, allowing the filter to remain dry during non-operational periods. This periodic operation enables the circulated air to dry the filter when not in use, preventing bacterial growth while maintaining humidification performance when required.
3Device complexity
If the humidifying filter is fixed to the humidifying gear, then the structure is simplified, but the filter cannot be easily replaced when contaminated or damaged
Solution Approach 1:
The humidifying filter is designed as a separate, detachable component from the humidifying gear. The filter can be independently removed from the gear assembly, allowing easy replacement when contaminated or damaged. This segmentation maintains operational simplicity while enabling convenient maintenance and filter replacement.
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 solution enables effective humidification of dry air while preventing bacterial contamination of the humidifying filter, ensuring efficient operation and easy maintenance by allowing for the replacement of the humidifying gear module.
Implementation Method 1
a humidifying filter (280) provided inside the humidifying gear (210)... the humidifying filter (280) being spaced apart from the humidifying water
Implementation Method 2
if a blower fan is operated during humidification stoppage, purified dry air having passed through a filter assembly can be passed to the humidifying filter

AI summary
Disclosed is an air conditioner. The air conditioner includes a tray in which humidifying water is stored by a predetermined height, the tray being detachably attached to a main body, a humidifying gear rotatably arranged in the tray so as to be detachably attached to the tray, a lifter provided at a periphery of the humidifying gear, the lifter being submerged under the humidifying water so as to scoop up the humidifying water during rotation of the humidifying gear, and a humidifying filter provided in the humidifying gear and spaced apart from the humidifying water such that the humidifying water is supplied from the lifter to the humidifying filter during rotation of the humidifying gear.
