Wall-Mounted Drum Washer Structure for Low Vibration and Slim Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted drum type washing machines face challenges in reducing vibration and protrusion distance from the wall surface, limiting their installation flexibility and efficiency.
Innovation Solution
A wall-mounted drum type washing machine design featuring a rear panel mounted on the wall with a tub integral to it, a reinforcement unit connecting the tub and rear panel, and a buffer system to suppress vibrations, allowing for a smaller front-to-rear length and reduced vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the drum is supported by a moveable tub in a cabinet, then the drum can rotate freely during washing operations, but the machine must be installed on its bottom surface and cannot be wall-mounted
Solution Approach 1:
The tub and rear panel are merged into a single integral structure, eliminating the need for separate support mechanisms. This allows the washing machine to be wall-mounted while maintaining drum stability during operation.
Solution Approach 2:
The rear panel is pre-formed with reinforcement ribs and receiving portions that provide structural support and vibration damping capabilities before the drum operation begins, enabling wall-mounted installation without requiring additional support structures.
2Length of moving object
If the drum front-to-rear length is made similar to its diameter, then the drum structure is simplified, but the protrusion distance from the wall surface cannot be reduced
Solution Approach 1:
The drum is positioned at an angle relative to the rear panel, with its rotation axis inclined rather than perpendicular. This dimensional change allows the drum to fit within a smaller protrusion distance from the wall while maintaining adequate washing space.
Solution Approach 2:
The drum is nested within the tub structure, with the box unit surrounding the drum and the cover unit covering the front panel. This nested arrangement optimizes space utilization and reduces the overall protrusion distance.
3Object-affected harmful factors
If the drum is supported by a moveable tub, then the drum can rotate during washing, but vibration cannot be reduced
Solution Approach 1:
The rear panel is pre-formed with reinforcement ribs and a curved upper end that act as vibration dampers before vibration occurs. The buffer unit is positioned to provide cushioning support to the tub, reducing vibration transmission during drum rotation.
Solution Approach 2:
The buffer unit acts as an intermediary between the tub and the rear panel, absorbing and dampening vibrations while allowing the drum to rotate freely within the tub during washing operations.
4Adaptability or versatility
If the power line extends from the control block through the rear panel, then electrical connection is established, but the power line may interfere with wall mounting and exterior finish
Solution Approach 1:
The power line routing is extracted from the main rear panel structure and guided through a separate guide unit with fixing portions. This separates the electrical connection function from the mounting structure, allowing clean wall mounting while maintaining electrical connectivity.
Solution Approach 2:
The guide unit serves as an intermediary structure that manages the power line extension from the control block through the rear panel. It provides a dedicated pathway and fixing mechanism that prevents the power line from interfering with wall mounting and exterior finish quality.
