Washer Spray Nozzle Assembly for Even Tub Soaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional top load type washing machines suffer from uneven fabric soaking due to the placement of water and detergent supply units, leading to deteriorated washing and rinsing performances.
Innovation Solution
A fabric treating machine equipped with a spray nozzle system that adjusts its spray direction and angle to ensure even water distribution across the inner tub, including a spray nozzle combining unit that secures the nozzle to the machine to prevent overflow and ensure reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If water supply unit is disposed at one side of the top of the cabinet, then the structure is simple, but fabric is not evenly soaked and washing performance deteriorates
Solution Approach 1:
The water supply system is segmented into multiple spray nozzles positioned at different locations (front, rear, left, right sides) of the inner tub. Each nozzle independently supplies water to different regions, transforming a single-point supply into a distributed multi-point supply system that achieves even fabric soaking while maintaining structural simplicity
Solution Approach 2:
The water supply approach transitions from a single vertical dimension (top-down spray) to three-dimensional coverage by positioning nozzles at multiple locations around the inner tub. This spatial distribution in multiple dimensions ensures comprehensive water coverage across the fabric load, resolving the contradiction between simple structure and effective washing performance
2Manufacturing precision
If spray nozzle is added to improve water distribution, then fabric soaking evenness improves, but device complexity increases
Solution Approach 1:
The spray nozzle assembly serves multiple functions: water distribution, fabric soaking, and cleaning. By designing a multi-functional component that integrates these functions, the system achieves improved water distribution evenness without proportionally increasing overall system complexity
Solution Approach 2:
The spray nozzle system is designed to be self-regulating and self-cleaning through the washing machine's existing water flow and pressure mechanisms. The nozzles utilize the machine's own water supply pressure to achieve proper spray distribution without requiring additional complex control systems, maintaining simplicity while improving performance
3Reliability
If spray nozzle is securely fitted to prevent overflow, then reliability improves, but ease of assembly may deteriorate
Solution Approach 1:
The spray nozzle is designed as a separable, detachable component that can be easily removed and reinstalled. This extraction design allows the nozzle to be securely fitted during operation for reliability while enabling simple assembly and disassembly for maintenance or replacement, resolving the contradiction between fitting stability and assembly ease
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 system effectively soaks fabric evenly, improving washing and rinsing performances by ensuring water reaches the bottom and sidewalls of the tub, regardless of load conditions, and enhances reliability and stability through secure nozzle fitting and optimal water distribution.

AI summary
A fabric treating machine includes a spray nozzle for spraying water supplied from a water supply passage into an inner tub and a spray nozzle combining unit for combining the spray nozzle with a case. Fabric loaded in the inner tub can be effectively soaked through the spray nozzle. Furthermore, a spray direction of the spray nozzle can be accurately adjusted when the spray nozzle is fitted in the case, and thus the spray nozzle can be easily fitted in the case and water sprayed through the spray nozzle can be prevented from overflowing.
