Solution Overview
Problem
Conventional space cleaning devices face challenges in maintaining a stable concentration of hypochlorous acid during micronization operations, especially in high humidity seasons, as hypochlorous acid vaporizes more easily than water, leading to reduced effectiveness in releasing the acid at set concentrations.
Innovation Solution
A space cleaning device equipped with a humidifying and cleaning unit that micronizes hypochlorous acid water and a controller that manages the water storage by draining and refilling hypochlorous acid water based on time-specific information to maintain optimal concentrations, combined with a hypochlorous acid water generation device that electrolyzes chloride solutions for continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hypochlorous acid water is continuously micronized and released in high humidity conditions, then the sterilization function is maintained, but the hypochlorous acid concentration decreases due to excessive vaporization
Solution Approach 1:
The controller performs a first treatment to drain and refill hypochlorous acid water before the concentration drops below the reference level. This preliminary action prevents the concentration from falling too low, ensuring the sterilization function remains reliable while accounting for accelerated vaporization in high humidity conditions.
Solution Approach 2:
The system uses time information and reference concentration values to determine when to perform the first treatment. This feedback mechanism allows the controller to adjust water refilling timing based on operational duration and environmental conditions, maintaining optimal hypochlorous acid concentration despite varying vaporization rates.
2Duration of action of moving object
If the micronization operation is performed continuously to maintain sterilization效果, then the cleaning function is sustained, but the hypochlorous acid is depleted faster than expected
Solution Approach 1:
The controller performs the first treatment periodically based on time information, draining and refilling hypochlorous acid water at predetermined intervals. This periodic action ensures continuous operation is maintained while preventing excessive depletion of hypochlorous acid, as the system proactively replenishes the substance before complete consumption occurs.
Solution Approach 2:
The system performs water refilling as a preliminary action before the hypochlorous acid is completely consumed. By timing the refilling operation based on predetermined time information and reference concentration values, the system ensures continuous availability of hypochlorous acid without interruption to the sterilization function.
3Device complexity
If water is refilled only when the storage unit is depleted, then the device complexity is minimized, but the hypochlorous acid concentration cannot be maintained at optimal levels
Solution Approach 1:
The controller incorporates a feedback mechanism that monitors operational time and compares it against predetermined time information to determine when the first treatment should be performed. This feedback approach maintains optimal hypochlorous acid concentration without requiring complex real-time concentration sensing, thus balancing device complexity with substance quality maintenance.
Solution Approach 2:
The system changes the operational parameter from simple water level monitoring to time-based control for performing the first treatment. By using time information as the control parameter instead of complex concentration measurement, the system maintains hypochlorous acid concentration at optimal levels while keeping the control system relatively simple.

AI summary
Humidifying and cleaning device of the present disclosure includes: centrifugal crushing unit that generates hypochlorous acid water micronized by a micronization operation for micronizing hypochlorous acid water stored in humidifier tank, and causes air flowing inside of the humidifying and cleaning unit to contain and release the hypochlorous acid water micronized by the micronization operation; and humidification controller that controls the micronization operation. Humidification controller is configured to perform a first treatment of draining the hypochlorous acid water stored in humidifier tank and supplying new hypochlorous acid water based on time information specified in advance during the micronization operation, that is, time information from when the micronization operation is started until a content of the hypochlorous acid contained in the hypochlorous acid water stored in humidifier tank becomes less than or equal to a reference content.
