Clothes dryer and method for performing sterilization course thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothes dryers lack efficiency in sterilization processes as they do not differentiate between dry and wet states of the objects being dried, leading to suboptimal energy use and sterilization quality.
Innovation Solution
A clothes dryer equipped with sensors to detect the dry state of objects, a heating unit, blower, and a processor to control temperature and rotation speed, allowing for distinct sterilization courses based on the object's dry state, optimizing energy use and sterilization quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a sterilization course is performed collectively without discriminating the state of the object to be dried, then the sterilization process is simplified, but energy efficiency and sterilization quality are lowered
Solution Approach 1:
The patent applies dynamics by making the sterilization process adaptive rather than static. The control unit dynamically adjusts sterilization parameters (temperature, time, airflow) based on real-time sensor feedback about the object's state (wet/dry). This allows the system to optimize energy consumption and sterilization quality for each specific condition while maintaining operational simplicity through automated control.
2Ease of operation
If a sterilization course is performed collectively without discriminating the state of the object to be dried, then the operation is easier, but sterilization quality is lowered
Solution Approach 1:
The patent implements feedback control by using sensors to detect the state of objects in the drum and providing this information to the control unit. The control unit then adjusts sterilization parameters based on this feedback, ensuring high sterilization quality for both wet and dry objects. The system remains easy to operate because the control automation handles the complexity, requiring only that the user place objects in the drum and select a sterilization mode.
3Use of energy by moving object
If different sterilization courses are performed according to the dry state of the object to be dried, then energy efficiency and sterilization quality are improved, but device complexity increases
Solution Approach 1:
The system applies self-service by automatically detecting the object state and selecting appropriate sterilization parameters without user intervention. The sensors and control unit work together to autonomously determine whether objects are wet or dry and adjust the sterilization process accordingly. This automation handles the increased complexity internally, allowing the user to benefit from optimized performance without needing to understand or manually configure the complex parameters.
