Washing Machine Spray Unit Mounting Structure to Prevent Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines require additional injection structures for spray units to distribute washing water effectively, which can lead to instability and increased complexity, necessitating a more robust fixing mechanism for the spray units.
Innovation Solution
A fixing unit with a mounting structure that includes recessed grooves and protruding ribs to securely attach the spray unit to the washing machine's circumferential direction, preventing movement and ensuring proper alignment and operation of the spray nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional injection structures are added to spray washing water at multiple points, then water distribution effectiveness is improved, but device complexity and structural stability deteriorate
Solution Approach 1:
The spray unit is integrated directly into the fixing unit, merging the water injection function with the structural support function. This eliminates the need for separate injection structures while achieving multi-point water distribution through nozzles attached to the spray unit.
Solution Approach 2:
The fixing unit serves multiple functions: it provides structural support, enables circumferential rotation of the spray unit, and integrates the water injection system. This multi-functionality reduces overall device complexity while maintaining effective water distribution.
2Productivity
If additional injection structures are added to spray washing water at multiple points, then water distribution effectiveness is improved, but structural stability deteriorates
Solution Approach 1:
By merging the spray unit with the fixing unit through direct coupling, the spray unit benefits from the structural stability of the fixing unit. The mounting structure provides rigid support while allowing necessary rotation, ensuring stability during operation.
Solution Approach 2:
The fixing unit includes segmented mounting structures (mounting grooves and ribs) that provide stable fixation at multiple points. This segmented approach distributes mechanical loads and maintains stability while accommodating the spray unit's rotational movement.
3Stability of the object's composition
If a robust fixing mechanism is used to stabilize the spray unit, then structural stability is improved, but device complexity increases
Solution Approach 1:
The fixing mechanism is merged with the fixing unit's mounting structure, which already serves structural support functions. The mounting grooves and ribs provide stable fixation without requiring additional complex fastening mechanisms, as the structure itself serves as the fixing mechanism.
Solution Approach 2:
The fixing unit's mounting structure provides self-contained fixation capabilities through its integrated grooves and ribs. The spray unit is stabilized by the structure's own geometric features rather than requiring separate fastening components, simplifying the overall design.

AI summary
A washing machine includes a cabinet; a tub which is disposed in the cabinet and in which washing water is stored; a rotating tub that is disposed in the tub and accommodates laundry; a spray unit configured to spray washing water into the rotating tub; and a fixing unit to which at least a portion of the spray unit is coupled and which includes a mounting structure provided at at least a portion of a circumferential direction of the fixing unit so as to fix the spray unit. The mounting structure in which a spray unit can be fixed by a fixing unit provides that movement of the spray unit can be prevented when a washing machine operates and the spray unit can be assembled in a desired position of the washing machine.
