Multi-Nozzle Water Applicator for Even Top-Load Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional top-load washing machines suffer from uneven distribution of water and detergent due to their side-mounted supply units, leading to suboptimal washing and rinsing performance.
Innovation Solution
The washing machine incorporates a liquid applicator unit with multiple nozzles that eject water in a flat fan pattern, covering a broader area without overlap, ensuring even distribution and soaking of laundry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If water and detergent are supplied from side-mounted units in conventional top-load washing machines, then the supply mechanism is simple and compact, but water and detergent are forced to be supplied only to a lower portion of a side of the washing tub, resulting in uneven distribution and deterioration of washing and rinsing performance
Solution Approach 1:
The liquid applicator unit is divided into multiple nozzles (first nozzle, second nozzle, third nozzle, fourth nozzle) arranged at different positions and orientations. Each nozzle is responsible for spraying liquid to a specific region of the washing tub, ensuring comprehensive and uniform coverage. This segmentation of the spraying function into multiple discrete nozzle units resolves the contradiction by achieving uniform distribution without requiring a single complex supply mechanism.
Solution Approach 2:
Different nozzles are configured with different spray directions and orientations to address specific local needs within the washing tub. The first and second nozzles spray to opposite first regions, while the third and fourth nozzles spray to opposite second regions. This local customization of spray characteristics ensures that each region receives appropriate liquid distribution, resolving the contradiction between simple supply mechanism and uniform distribution.
2Quantity of substance
If a single water supply unit is used in conventional washing machines, then the device structure is simple, but water cannot be evenly applied to the laundry throughout the washing tub
Solution Approach 1:
The water supply function is segmented into multiple nozzles positioned at different locations (upper side, lower side) with different spray orientations. This segmentation allows water to be applied to multiple regions simultaneously, achieving even distribution across the laundry while maintaining a relatively simple overall device structure.
Solution Approach 2:
The nozzles are arranged in different spatial dimensions and orientations (upper side nozzles, lower side nozzles, opposite regions) to create three-dimensional water distribution. This dimensional arrangement ensures comprehensive coverage of the laundry throughout the washing tub, resolving the contradiction between simple structure and even application.

AI summary
Provided is a washing machine that includes a washing tub to accommodate laundry, the washing tub provided to be rotatable, and a liquid applicator that sprays a liquid to prescribed regions inside the washing tub. The liquid applicator may include a first nozzle having a first outlet arranged in a first direction to spray the liquid toward a first region of the washing tub, and a second nozzle having a second outlet arranged in a second direction to spray the liquid toward a second region of the washing tub. The first and second directions may be different directions.
