Stationary Rack Dry Chamber Airflow Layout for Wrinkle-Free Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses face challenges in minimizing wrinkles and achieving high drying efficiency, as they often supply heated air while rotating the drum, leading to low drying efficiency and increased drying time.
Innovation Solution
The apparatus features a hinge unit for adjusting the rotation angle of racks and includes two independently partitioned dry spaces with an air supply system that directs heated air between the racks, optimizing air circulation and heat exchange for improved drying efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If heated air is supplied via the bottom surface of the dry chamber, then wrinkles on clothes are minimized, but drying efficiency becomes low
Solution Approach 1:
The dry chamber is divided into multiple air supply zones with separate air supply holes at different locations (front, rear, and side walls). This segmentation allows heated air to be supplied from multiple directions simultaneously, improving drying efficiency while maintaining the benefit of reduced wrinkles through uniform air distribution.
Solution Approach 2:
Different regions of the dry chamber are provided with air supply holes at optimized locations to create local quality variations in air flow patterns. The air supply unit supplies heated air to specific zones based on their drying needs, achieving both wrinkle minimization and high drying efficiency through localized air supply optimization.
2Productivity
If heated air is supplied to the drum while rotating, then drying process is continuous, but wrinkles remain on clothes
Solution Approach 1:
Instead of rotating the drum to achieve continuous drying, the invention inverts the approach by using stationary racks with optimized air supply from multiple directions. This inversion eliminates the drum rotation mechanism that causes wrinkles while maintaining continuous drying through improved air circulation patterns.
Solution Approach 2:
The mechanical drum rotation system is replaced with a stationary rack system combined with a controlled air supply system. This substitution eliminates mechanical contact and rotation that cause wrinkles, relying instead on thermal convection and optimized air flow to achieve continuous and efficient drying.
3Ease of operation
If multiple racks are provided in the dry chamber, then clothes can be arranged in predetermined spaces, but air circulation becomes restricted
Solution Approach 1:
Air supply holes are strategically positioned at different locations including front wall, rear wall, and side walls of the dry chamber. This local quality approach ensures that air circulation is optimized for each region, maintaining efficient air flow even with multiple racks present, while still allowing proper clothes arrangement on the racks.
