Laundry treatment apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses fail to provide satisfactory deodorization and wrinkle removal, as they typically perform these functions during drum rotation, which limits the spread of laundry and requires additional tools for crease-making, such as irons, after washing or drying.
Innovation Solution
A laundry treatment apparatus with a cabinet, a feeder for air or moisture, and a presser that keeps laundry spread and applies steam or hot air to remove wrinkles and create creases, while a support structure and guide prevent laundry from deviating and a fixing member secures it in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laundry is processed during drum rotation, then washing and drying functions are achieved, but deodorization and wrinkle removal are insufficient
Solution Approach 1:
The invention divides the laundry treatment process into distinct functional zones: a washing/drying zone during drum rotation and a separate pressing zone with a presser for deodorization and wrinkle removal. This segmentation allows each zone to optimize its specific function, with the presser applying localized pressure and heat to achieve satisfactory wrinkle removal and deodorization that cannot be achieved during drum rotation alone.
Solution Approach 2:
The presser is positioned to act on laundry after the drum rotation has completed its washing or drying cycle. The laundry is first prepared through washing or drying, then the presser applies pressing action with steam or hot air to remove wrinkles and deodorize. This preliminary action sequence ensures that the laundry is in the optimal state before pressing, improving the effectiveness of wrinkle removal and deodorization.
2Adaptability or versatility
If a presser is added to the laundry treatment apparatus, then crease making capability is improved, but device complexity increases
Solution Approach 1:
The presser is integrated into the existing drum structure of the laundry treatment apparatus. The presser can be positioned within the drum or on the drum surface, merging the pressing function with the existing washing/drying drum. This integration allows crease making capability to be added without requiring a completely separate device, thereby reducing the increase in device complexity while still achieving versatile laundry treatment functions.
Solution Approach 2:
The presser is designed to perform multiple functions: it can apply pressure to remove wrinkles, deodorize laundry through steam or hot air, and create creases in specific areas. This multi-functionality allows a single added component to provide versatile laundry treatment capabilities, reducing the need for multiple separate devices and thereby limiting the increase in device complexity.
3Device complexity
If laundry is not spread during processing, then drum rotation is simple, but wrinkle removal and deodorization effectiveness decrease
Solution Approach 1:
The presser is designed with dynamic positioning capabilities, allowing it to move to different locations on the drum or within the laundry load. This dynamic adjustment enables the presser to adapt to the position and state of the laundry, ensuring effective contact and pressing action regardless of how the laundry is arranged during drum rotation. The dynamic design maintains simple drum rotation mechanics while improving wrinkle removal and deodorization effectiveness.
Applied Scientific Principles
