Washing machine and washing drum thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines with a single drum fail to effectively separate clothes requiring special care, leading to potential cross-contamination and skin allergies due to residual particles.
Innovation Solution
A washing drum design featuring a large container with a detachable small container, where the small container is positioned within the large one, allowing for separate washing of special care items, with a gap between the containers to prevent water flow and utilize a wave wheel and hinge mechanism for independent rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single washing drum is used, then the device complexity is low, but the ability to separate clothes needing special care is insufficient leading to cross-contamination
Solution Approach 1:
The patent implements a nested container structure where a small container is placed inside a large container. The small container has a bottom wall that rests on the wave wheel, and its side wall extends upward to form an inner washing space. This nesting arrangement enables separate washing of special care items within the larger drum without requiring multiple independent drums, thus achieving separation functionality while controlling structural complexity.
Solution Approach 2:
The washing drum is segmented into two functional zones: the large container for general washing and the small container for special care items. The small container is detachably positioned on the wave wheel, allowing it to be removed when not needed. This segmentation enables independent washing spaces while maintaining a single integrated drum structure.
2Object-affected harmful factors
If the small container is tightly fitted to the large container, then structural stability is improved, but water flow between containers cannot be prevented
Solution Approach 1:
The patent applies local quality by creating a specific gap structure between the small container and large container. The gap is formed between the side wall of the small container and the inner wall of the large container, with a specified distance range. This localized gap arrangement prevents water flow between containers while maintaining structural stability through other means such as the positioning of the small container bottom on the wave wheel and support structures.
3Productivity
If the small container and large container operate together, then washing efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic operation modes where the small container can be selectively positioned on the wave wheel based on washing needs. When special care items need washing, the small container is installed and both containers operate together. When only general washing is needed, the small container is removed and only the large container operates. This dynamic configuration allows the system to adapt energy consumption to actual washing requirements while maintaining high washing efficiency when both containers are used.
