Reciprocating Hanger Bar Layout for Larger Laundry Treating Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses have limitations in deodorizing and wrinkle-removing due to the crumpled state of laundry during drum rotation, leading to insufficient effectiveness in these processes.
Innovation Solution
A laundry treating apparatus with a driving part located outside the treating chamber, utilizing a hanger bar and power converting mechanism to reciprocate the hanger bar, allowing for improved space utilization and increased capacity within the chamber, enabling efficient drying, deodorizing, and wrinkle removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the driving part is placed inside the treating chamber, then the structure is simpler, but the treating chamber capacity is reduced and the apparatus width increases
Solution Approach 1:
The driving part is relocated from the horizontal plane inside the treating chamber to the vertical direction outside the chamber. The motor is positioned above the treating chamber, and power is transmitted vertically downward through a shaft and belt mechanism to the hanger bar, changing the spatial arrangement from horizontal to vertical dimension.
Solution Approach 2:
A belt is introduced as an intermediary power transmission element between the motor and the hanger bar. The belt connects the motor shaft to the hanger bar, enabling flexible power transmission while allowing the motor to be positioned outside the treating chamber, thus resolving the conflict between chamber capacity and driving part placement.
2Area of stationary object
If the driving part is placed inside the treating chamber, then the power transmission distance is shorter, but the apparatus width increases and space efficiency decreases
Solution Approach 1:
The power transmission path is reconfigured from horizontal to vertical dimension. The motor is positioned above the treating chamber, and power is transmitted downward through a vertical shaft and belt mechanism, utilizing the vertical space outside the chamber rather than consuming horizontal space within the chamber.
3Volume of moving object
If the hanger bar is used instead of drum rotation, then the treating chamber capacity is maximized, but the mechanism for generating shaking force becomes more complex
Solution Approach 1:
The hanger bar is designed to reciprocate dynamically between upward and downward movements rather than rotating statically. The belt mechanism converts the motor's rotational motion into reciprocating linear motion of the hanger bar, creating dynamic shaking forces that improve wrinkle removal and deodorizing effectiveness while maximizing chamber capacity.
