Laundry treating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses are inadequate in preventing or removing wrinkles from laundry, as they provide continuous friction, which is insufficient for drying and wrinkle removal.
Innovation Solution
A laundry treating apparatus with a support assembly that fixes laundry in an unfolded state, using air or water vapor, and includes a water discharge tank for condensate collection and a water supply tank for moisture supply, along with a movable door system to enhance user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous friction is applied to laundry during treating operation, then drying efficiency is improved, but wrinkle removal capability deteriorates
Solution Approach 1:
The drum is designed to rotate periodically between forward and reverse directions, creating alternating friction patterns that prevent continuous rubbing in one direction. This periodic motion allows laundry to be lifted and dropped repeatedly, effectively removing wrinkles while maintaining drying efficiency through sustained air circulation and moisture extraction.
2Productivity
If laundry is rubbed continuously with drum, then drying function is enhanced, but wrinkle prevention capability is reduced
Solution Approach 1:
The drum rotation direction is dynamically changed between forward and reverse modes during the treating operation. This dynamic adjustment transforms the static rubbing action into a dynamic lifting-and-dropping motion, which prevents wrinkles from forming while maintaining the drying function through continuous air flow and moisture removal.
3Ease of operation
If chamber door is extended to expose water tanks, then user accessibility is improved, but chamber sealing is compromised
Solution Approach 1:
The chamber door is segmented into multiple sections: a fixed portion that maintains chamber sealing and a movable extension portion that can be independently extended to expose water tanks. This segmentation allows the door to simultaneously maintain sealing integrity while providing user accessibility to water tanks when needed.
Solution Approach 2:
The chamber door incorporates a movable extension mechanism that allows the door to dynamically adjust its position. The door can remain closed to maintain sealing during operation, and be extended only when user intervention is needed to access water tanks, thus balancing sealing reliability with operational convenience.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively dries, deodorizes, and removes wrinkles from laundry while improving user convenience by allowing the laundry to be fixed in an unfolded state and automatically extending water tanks for efficient condensate and moisture management.
Implementation Method 1
a first heat exchanger provided inside the duct to dehumidify air entering the duct
Implementation Method 2
a second heat exchanger provided inside the duct to heat air passing through the first heat exchanger

AI summary
A laundry treating apparatus includes a cabinet with an insertion opening defined in a front face, a laundry receiving space in the cabinet, a support assembly in the laundry receiving space for supporting laundry, and a first chamber including an air supply part for supplying dehumidified and heated air into the laundry receiving space. A communication opening in the front face of the cabinet opens to the first chamber. A chamber door is configured to open and close the communication opening. A water discharge tank is detachably connected to the chamber door and stores condensate water discharged from the air supply part. A chamber door conveying part reciprocates the chamber door, and moves the support assembly toward the insertion opening when the door opens the insertion opening.
