Washing Machine Stator Mounting for Tub Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines fail to effectively reduce vibrations from the stator, leading to noise issues due to direct fastening of the stator to the tub, which results in vibration transmission.
Innovation Solution
Incorporation of a vibration reduction member in the stator, comprising bearing couplers and deforming parts that are fastened to the bearing housing to absorb and deform vibrations, thereby reducing their transmission to the tub.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the stator is directly fastened to the bearing housing, then the structure is simple and easy to manufacture, but the vibration from the stator is effectively transmitted to the tub causing noise
Solution Approach 1:
The patent introduces a vibration reduction member as an intermediary component between the stator and the bearing housing. This member includes a vibration reduction plate with elastic protrusions that make contact with the bearing housing, creating a flexible connection that reduces vibration transmission while maintaining structural support. The intermediary structure effectively decouples the direct rigid connection, thereby reducing noise without significantly complicating manufacturing.
2Device complexity
If the stator is directly fastened to the bearing housing, then the structural complexity is low, but the vibration transmission to the tub is high
Solution Approach 1:
The vibration reduction member incorporates elastic protrusions that can dynamically deform in response to vibrations from the stator. These elastic elements provide a flexible, dynamic connection rather than a rigid static one, allowing the structure to adapt to vibrational forces while maintaining overall stability. The dynamic characteristic of the elastic protrusions enables vibration absorption while preserving the structural integrity of the motor assembly.

AI summary
A washing machine including a vibration reduction member formed in a stator is provided. Therefore, when a motor rotates according to operation of the washing machine, delivery of a vibration due to a repulsive force of the stator to a bearing housing can be efficiently reduced. Further, a vibration of a tub fastened to the bearing housing due to the vibration is prevented and noise due to the vibration of the tub is reduced.
