Clothing Dryer Mist Control for Adaptive Wrinkle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothing dryers face challenges in effectively removing wrinkles from clothing, as the amount of mist sprayed can be insufficient or excessive, leading to inadequate wrinkle removal performance.
Innovation Solution
A control method that adjusts the amount of mist sprayed based on the type and weight of clothing, using a mist generator to diffuse the mist while intermittently rotating the drum, and converting the mist into steam at specific temperatures to enhance wrinkle removal, with the goal of achieving optimal wrinkle removal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed amount of mist is sprayed during wrinkle removal, then the control process is simple, but the wrinkle removal performance is insufficient for different clothing types and weights
Solution Approach 1:
The patent applies dynamics by making the mist spraying amount adaptive rather than fixed. The control unit dynamically adjusts the mist quantity based on real-time detection of clothing weight and type, transforming a static control system into a dynamic one that responds to varying conditions, thereby improving wrinkle removal performance without requiring complex manual intervention
Solution Approach 2:
The patent implements feedback through sensors that detect clothing weight and type, transmitting this information to the control unit. The control unit then adjusts the mist spraying amount based on this feedback, creating a closed-loop control system that automatically optimizes wrinkle removal performance for different clothing items
2Manufacturing precision
If mist is sprayed continuously, then the wrinkle removal coverage is improved, but the clothing becomes over-wetted and requires additional drying time
Solution Approach 1:
The patent applies partial action by spraying mist in controlled amounts rather than continuously. The control unit calculates and delivers only the necessary quantity of mist based on clothing characteristics, avoiding excessive wetting while still achieving effective wrinkle removal, thus reducing additional drying time
Solution Approach 2:
The patent changes the parameter of mist quantity from a constant high value to a variable amount optimized for each clothing item. By adjusting the mist quantity parameter based on detected clothing properties, the system achieves effective wrinkle removal with minimal excess moisture, reducing drying time requirements
3Manufacturing precision
If the drum rotates continuously during mist spraying, then the mist distribution is uniform, but the mist does not have sufficient time to penetrate and rearrange fabric fibers
Solution Approach 1:
The patent applies periodic action by alternating between drum rotation and stationary phases during mist spraying. The drum rotates to distribute mist uniformly, then stops to allow sufficient time for mist penetration and fiber rearrangement. This periodic cycle optimizes both uniform distribution and effective fiber treatment
Solution Approach 2:
The patent applies preliminary action by first rotating the drum to distribute mist uniformly across the clothing surface before allowing the drum to stop for fiber rearrangement. This preliminary distribution phase ensures even coverage before the penetration phase begins, optimizing overall effectiveness

AI summary
Disclosed herein is a control method of clothing dryer that sprays an appropriate amount of mist based on the amount of clothing and dries the clothing at a fiber rearrangement temperature to remove wrinkles from the clothing. Standard regain of clothing is confirmed, mist is sprayed such that an amount of mist equivalent to approximately twice the standard regain reaches the clothing, and the clothing is dried at the fiber rearrangement temperature, whereby wrinkles are removed from the clothing.
