Auxiliary Washing Unit Structure for Separate Laundry Cycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines lack a dedicated space for auxiliary washing of specific items like socks and undergarments, limiting their ability to perform separate and efficient washing cycles.
Innovation Solution
Incorporation of an auxiliary washing unit within the washing machine, featuring an auxiliary washing space and discharging assembly that allows for independent washing and drainage, enabling separate washing and discharge of laundry from the main washing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a washing machine has only a main washing space formed by the fixed tub and rotating tub, then the structure is simple, but no separate space for washing specific items like socks and undergarments is available
Solution Approach 1:
The auxiliary washing unit is nested within the door assembly of the washing machine. The door assembly serves as the housing for both the main door and the auxiliary washing unit, allowing the auxiliary washing space to be integrated into the existing structure without requiring additional external space. This nesting approach enables the washing machine to perform both main washing and auxiliary washing functions while maintaining a compact overall structure.
Solution Approach 2:
The washing machine is segmented into two independent washing spaces: the main washing space (formed by the fixed tub and rotating tub) and the auxiliary washing space (formed by the auxiliary washing unit). This segmentation allows separate washing cycles for different types of laundry, providing versatility while keeping each washing space relatively simple in structure.
2Adaptability or versatility
If an auxiliary washing unit is added to the door assembly, then separate auxiliary washing is enabled, but the door assembly structure becomes more complex
Solution Approach 1:
The auxiliary washing unit is merged with the door assembly, where the door assembly serves as the structural housing for both the main door and the auxiliary washing unit. The discharging assembly is also integrated into this combined structure, allowing it to serve both the auxiliary washing unit and the main washing space. This merging reduces the need for separate components and simplifies the overall structure despite adding functionality.
Solution Approach 2:
The discharging assembly is designed with multi-functionality: it can discharge laundry from the auxiliary washing unit to the main washing space, and also function as part of the door assembly structure. This universal component serves multiple purposes, reducing the total number of components needed and mitigating the increase in structural complexity.
3Productivity
If laundry is discharged from auxiliary washing space to main washing space, then washing efficiency is improved, but the discharging mechanism adds complexity
Solution Approach 1:
The discharging assembly operates to transfer laundry from the auxiliary washing unit to the main washing space, enabling the system to serve itself by consolidating laundry into the main space for subsequent processing. This self-service capability improves washing efficiency by allowing the auxiliary washed items to be combined with main washing items for a single drying cycle, reducing total processing time.
Solution Approach 2:
The discharging assembly acts as an intermediary mechanism between the auxiliary washing unit and the main washing space. It provides a controlled pathway for transferring laundry, using a discharging door that can be opened or closed as needed. This intermediary structure enables efficient laundry transfer while maintaining separate washing spaces during operation.

AI summary
Provided is a washing machine including an auxiliary washing unit configured with an auxiliary washing space formed separately from a main washing space formed in a rotating tub, and a discharging assembly by which the auxiliary washing space and the main washing space are selectively in communication with each other. Through such a structure, auxiliary washing may be independently performed, and washing efficiency may be enhanced.
