Wet Mop Rag Module With Steam Generator and Overheating Shut-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet mop rag modules for cleaners face challenges in effectively sterilizing and removing debris, as they often fail to supply high-temperature water or steam consistently, leading to incomplete cleaning and potential overheating issues, and require separate components that increase weight and inconvenience during dry cleaning.
Innovation Solution
A wet mop rag module with a steam generator that includes a heating chamber, a heater, and an overheating shut-off device, allowing for controlled temperature adjustment and phase selection of moisture supplied to the mop rag, while maintaining rotation during power cutoff to prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the water container or heater is disposed in the main body, then the steam generation function is integrated, but the weight makes it difficult for the user to conveniently clean the floor during dry cleaning
Solution Approach 1:
The cleaner is divided into a main body and a detachable mop rag module. The water container and heater are disposed in the mop rag module rather than the main body, allowing the module to be detached during dry cleaning operations. This segmentation enables the system to provide steam generation functionality when needed while avoiding the weight penalty during dry cleaning, as the heavy components remain in the removable module.
2Temperature
If the steam generator heats water continuously, then high-temperature steam is supplied for sterilization, but overheating may occur without proper temperature control
Solution Approach 1:
The steam generator incorporates a temperature sensor that continuously monitors the heating chamber temperature and provides feedback to the control unit. When the temperature reaches a predetermined threshold, the control unit automatically adjusts or stops the heating operation, preventing overheating while ensuring sufficient temperature for sterilization. This closed-loop control system maintains reliable operation across varying conditions.
3Ease of manufacture
If the steam generator is disposed in the mop rag module, then the module can be easily replaced and spatial utilization is improved, but the power supply control becomes more complex
Solution Approach 1:
The power supply system is segmented into a detachable connector that interfaces between the main body and the mop rag module. The connector includes contact terminals that automatically connect when the module is attached and disconnect when removed. This segmented power supply design simplifies the control architecture by isolating the complex heating control circuitry within the module while maintaining easy replaceability, as the entire module with its integrated power system can be swapped as a single unit.
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
Improves sterilization and debris removal efficiency by ensuring consistent high-temperature water or steam supply, prevents overheating, and maintains cleaning performance by separating power supply to the steam generator, enhancing user convenience and cleaning effectiveness.
Implementation Method 1
a heater disposed at a lower side of the heating chamber and configured to supply heat to the heating chamber
Implementation Method 2
an overheating shut-off device disposed at one side of the heating chamber and configured to cut off a supply of power to the heater when a temperature of the heating chamber is equal to or higher than a predetermined reference temperature
