Dual-Drum Washer Structure With Integrated Drum Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional double-drum washing machines face issues with space occupancy, vibration noise, and instability due to gaps between drums and the need for additional counterweights, which increase costs and reduce vibration noise effectiveness.
Innovation Solution
The double-drum washing machine features integrally molded connecting parts between drums, reducing the need for auxiliary fixed parts and counterweights, with a stable and compact design that minimizes vibration and noise through a detachable connection system with reinforcing ribs and elastic buffer layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two drums are respectively arranged in their respective frame with a gap between them, then the structure is simple and easy to manufacture, but the space occupied is larger and vibration noise is increased
Solution Approach 1:
The patent merges the two separate drum frames into a single integrated frame structure. The first outer drum and second outer drum are both supported by the same frame, eliminating the gap between separate frames and reducing vibration noise while maintaining manufacturing simplicity
Solution Approach 2:
The patent optimizes the spatial arrangement of drums within the frame by adjusting their positions in different dimensions. The drums are arranged to minimize gap space while maintaining proper operational clearance, effectively utilizing three-dimensional space within the integrated frame
2Volume of stationary object
If the two drums are connected to narrow the space, then the space occupancy is reduced and noise is lowered to a certain degree, but a regulating and balancing device including a counterweight needs to be added on the outer drum, increasing cost and vibration reduction effectiveness remains unobvious
Solution Approach 1:
The patent combines the connection function and space reduction into the integrated frame structure itself. The frame naturally connects both drums through its unified design, eliminating the need for separate connection devices and counterweights, thereby reducing space occupancy without increasing device complexity
Solution Approach 2:
The integrated frame structure serves multiple functions simultaneously: it supports both drums, connects them together, provides structural stability, and eliminates the need for additional counterbalancing devices. The structure is self-sufficient and does not require auxiliary components
3Adaptability or versatility
If the element connecting double drums is set separately, then the mounting is flexible, but the mounting is tedious and problems such as falling off are easily caused due to vibration influence, resulting in poor stability
Solution Approach 1:
The patent merges the connection elements into the frame structure itself rather than using separate mounting components. The integrated frame provides inherent connection between drums through its unified construction, eliminating tedious separate mounting operations while ensuring stable connection that resists vibration-induced loosening or detachment

AI summary
A double-drum washing machine comprises a first outer drum and a second outer drum which are respectively provided with a drum inside, wherein the second outer drum is provided with a connecting part which protrudes out of a surface of the second outer drum and which is molded integrally, the connecting part extends towards the first outer drum along a radial direction from the surface of the second outer drum, and an end part of the connecting part is in detachable connection with the first outer drum. Double drums of the double-drum washing machine are connected to be almost integrated, therefore, auxiliary fixed parts are reduced, and the connection between double drums is more stable, reliable and more compact, the vibration of the double-drum washing machine is effectively reduced during operation, the noise pollution of the double-drum washing machine is reduced, and additional counterweight is not required.
