Washing Machine Detergent Dispenser With Even Water Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machine dispensers fail to effectively distribute washing water to the detergent container, leading to inadequate mixing and dissolution of detergents, bleach, or fabric softener, due to insufficient water pressure and flow distribution.
Innovation Solution
The dispenser features a main water passage with an inclined slit subsidiary water passage that directs washing water from the inlet to the end passage, ensuring even distribution across the detergent container, enhancing the mixing of washing water with detergents through multiple holes on the bottom cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional water passage with multiple turning passages is used, then the water passage occupies much space of the bottom cover, but the water pressure gets lowered and washing water does not smoothly flow to the end water passage
Solution Approach 1:
The water passage is segmented into multiple independent channels (first water passage, second water passage, third water passage) that run parallel to each other. This segmentation allows water to flow through multiple paths simultaneously, maintaining water pressure while still occupying sufficient space for effective detergent dissolution.
2Ease of operation
If washing water pressure is insufficient, then washing water can be easily supplied through the water passage, but detergent, fabric softener or bleach does not get dissolved and diluted well
Solution Approach 1:
Different regions of the bottom cover are equipped with different water passage configurations. The first water passage supplies water to the front region, the second water passage supplies water to the middle region, and the third water passage supplies water to the rear region. This local differentiation ensures that detergent dissolution quality is improved in each specific area without requiring high overall water pressure.
3Stress or pressure
If the water passage is simplified to maintain water pressure, then water flows more smoothly, but washing water is not dispensed widely over the detergent container
Solution Approach 1:
The water passage system transitions from a single linear path to a multi-dimensional network with parallel channels running in the front-middle-rear direction. This dimensional expansion allows water to be dispersed widely over the detergent container while maintaining pressure through parallel flow paths, resolving the contradiction between pressure maintenance and wide dispersion.
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
This design ensures that washing water is widely scattered over the detergent container, improving the dissolution and distribution of detergents, bleach, or fabric softener, resulting in better washing performance.
Implementation Method 1
A subsidiary water passage is configured in the inlet water passage, where some quantity of washing water flowing therein is delivered to another water passage
Implementation Method 2
washing water fed from a water supplier, by being widely scattered over a detergent container. With that, washing water and detergent can be efficiently mixed

AI summary
The present invention provides a dispenser which evenly dispenses washing water to a detergent container. Within the dispenser, a slit of a subsidiary water passage is configured in a rib located between an inlet water passage where washing water enters the dispenser and an end water passage distant from the inlet water passage by the farthest. Some quantity of washing water running the inlet water passage is diverged and moves to the end water passage where washing water has been insufficiently supplied. Hereby, washing water is equally scattered over the dispenser and drops into the detergent container. The dissolving power can be much more enhanced.
