Humidification Filter Rotation Control for Water Absorption Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vaporization type humidification devices often experience excessive water absorption by the filter unit, leading to inefficient energy use and unnecessary water supply, as the filter unit continuously rotates at a constant speed, resulting in excessive water absorption beyond what is needed for vaporization.
Innovation Solution
A humidification device with a control unit that intermittently rotates the water storage or filter unit, switching between continuous and intermittent rotation based on predetermined times or rotation counts, and air blowing quantity, to optimize water absorption and conserve energy.

Engineering Contradiction Analysis
1Quantity of substance
If the filter unit continuously rotates at a constant speed, then water absorption is facilitated, but excessive water absorption occurs leading to energy waste
Solution Approach 1:
The filter unit alternates between rotating and stationary states in periodic cycles. During rotation, water is absorbed from the water tank; during stationary periods, water vaporizes and is blown out. This periodic operation prevents continuous rotation and excessive water absorption, thereby reducing energy waste while maintaining effective humidification.
Solution Approach 2:
The rotation speed and rotation period of the filter unit are dynamically adjusted based on operational requirements. The system transitions from constant-speed continuous rotation to variable-speed intermittent rotation, optimizing water absorption efficiency while preventing over-absorption and energy consumption.
2Stability of the object's composition
If the filter unit continuously rotates, then water is effectively spread uniformly, but water is supplied more than necessary
Solution Approach 1:
The filter unit performs intermittent rotation followed by stationary periods. During rotation phases, water is uniformly distributed across the filter surface; during stationary phases, the uniformly distributed water vaporizes. This periodic pattern achieves uniform water distribution without requiring continuous rotation, thereby preventing excessive water supply.
Solution Approach 2:
The system maintains continuous humidification output by alternating between water absorption (rotation phase) and water vaporization (stationary phase). The useful action of humidification continues without interruption even though the rotation is intermittent, ensuring uniform water distribution is maintained while avoiding water waste.
3Productivity
If the filter unit rotates at constant speed, then absorption is facilitated, but vaporization amount exceeds requirements
Solution Approach 1:
The rotation speed is dynamically controlled based on the vaporization requirements. During periods when vaporization is needed, the filter unit rotates at optimized speeds to absorb the appropriate amount of water. The rotation parameters are adjusted to match the actual humidification demand, preventing over-vaporization while maintaining absorption efficiency.
Solution Approach 2:
The control unit monitors the humidification status and adjusts the rotation behavior accordingly. When sufficient water has been absorbed for the required vaporization amount, the system reduces or stops rotation. This feedback mechanism ensures water absorption efficiency is maintained while preventing excessive vaporization beyond what is actually needed.

Implementation Method 2
a blower configured to send air passing through the filter unit to an outside of a device
Implementation Method 3
the water absorbed into the filter unit is vaporized and then air (that is, humidified air) containing the vaporized water is sent to an outside of the device

AI summary
Disclosed is a humidification device capable of satisfying both necessary and sufficient humidification abilities and energy conserving. A humidification filter unit is immersed into water and rotates to facilitate the absorption of water. When the time from stopping of the humidification operation to the restarting thereof is long and the amount of water absorption is insufficient, the humidification filter unit rotates continuously for a predetermined time when the humidification operation restarts, and then rotates intermittently. Meanwhile, when the time from stopping of the humidification operation to the restarting thereof is short and the amount water absorption is sufficient, the humidification filter unit rotates intermittently during the humidification operation. The rotating stop time of the humidification filter unit for each intermittent rotation is set depending on the air blowing quantity of a blower fan.
