Split Washing Drum Structure to Prevent Dirt and Water Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drum washing machines require periodic professional cleaning due to dirt accumulation and water retention, leading to secondary pollution and inefficiencies.
Innovation Solution
A drum washing machine design featuring a front and rear washing drum where the front drum rotates with a motor, preventing water accumulation on the outer walls and allowing for sealed operation, eliminating the need for periodic cleaning and enhancing water efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inner drum and outer drum are used in a washing machine, then the washing drum can be sealed, but the interlayer between the drums accumulates dirt and water that cannot be cleaned by users
Solution Approach 1:
The invention removes the outer drum from the traditional inner drum-outer drum structure, extracting the problematic interlayer space. By using only an inner drum that rotates together with the water, the design eliminates the harboring site for dirt and residual water, making the washing drum cleanable without requiring disassembly or professional cleaning services.
2Reliability
If an inner drum and outer drum are used in a washing machine, then the washing function is enhanced, but residual water accumulates in the interlayer causing bacterial growth
Solution Approach 1:
The invention extracts and removes the outer drum structure that creates the interlayer space. By eliminating this space, residual water cannot accumulate, thereby preventing the growth of bacteria and other harmful factors while maintaining the washing function through the inner drum rotating with the water.
3Reliability
If a traditional inner drum and outer drum structure is used, then the drum can be sealed, but the outer wall of the inner drum cannot be cleaned by users
Solution Approach 1:
The invention removes the outer drum structure, extracting the problematic interlayer space between the drums. This eliminates the area that cannot be cleaned by users, allowing the washing drum to be fully accessible and cleanable while maintaining sealing through the inner drum design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design prevents dirt accumulation on the outer drum walls, reduces water usage, and ensures effective washing without leakage, making the machine more user-friendly and water-saving.
Implementation Method 1
the front washing drum is operative to rotate along with a motor
Implementation Method 2
clothes and water in the washing drum are driven to rotate to lift clothes, and then let the clothes fall and be beaten
Implementation Method 3
a sealing door is further arranged on a side of the front washing drum adjacent to the door and window and is configured to seal the washing drum
