Detergent Drawer Insert for Liquid Detergent Without Laundry Staining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machine detergent supply apparatuses lack a dedicated chamber for liquid detergent, leading to direct contact with laundry, causing decoloration and discoloration, and do not allow easy switching between powdered and liquid detergents.
Innovation Solution
A detergent supply apparatus with a detachable liquid detergent container integrated into the powdered detergent chamber, featuring separate sections for main and preliminary washing, along with a siphon system for water drainage, preventing overflow and allowing easy detergent selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid detergent is directly poured onto laundry, then liquid detergent can be supplied to the washing machine, but decoloration and discoloration of laundry occurs
Solution Approach 1:
The detergent supply apparatus is segmented into separate functional chambers: a liquid detergent chamber for containing and dispensing liquid detergent, a powdered detergent chamber for powdered detergent, and a fabric softener chamber. This segmentation prevents liquid detergent from directly contacting laundry by providing a dedicated containment and dispensing system.
Solution Approach 2:
The liquid detergent chamber acts as an intermediary system between the liquid detergent source and the laundry. Water is supplied to the liquid detergent chamber where it mixes with the detergent, and the diluted mixture is then safely dispensed onto the laundry, preventing direct pouring and associated damage.
2Device complexity
If only a powdered detergent chamber is provided, then the detergent supply apparatus is simple in structure, but liquid detergent cannot be supplied and causes direct contact with laundry
Solution Approach 1:
The detergent supply apparatus is designed with multi-functionality to accommodate different detergent types. It includes a liquid detergent chamber for liquid detergent, a powdered detergent chamber for powdered detergent, and a fabric softener chamber, allowing the same apparatus to handle multiple detergent forms without requiring separate systems.
Solution Approach 2:
The liquid detergent chamber is detachably set within or adjacent to the powdered detergent chamber structure. This nested arrangement allows the liquid detergent functionality to be integrated into the existing powdered detergent apparatus framework, adding versatility while maintaining relatively simple overall structure and allowing easy configuration changes.
3Reliability
If liquid detergent container is tightly fitted in powdered detergent chamber, then liquid detergent can be contained, but it is difficult to detach and replace the container
Solution Approach 1:
The liquid detergent container is designed with dynamic mounting characteristics - it fits tightly during washing operations to ensure reliable containment and prevent leakage, but can be easily detached when needed for refilling or replacement. The detachable connection mechanism provides different states: secured during operation, removable when required.
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
Enables the safe and efficient supply of liquid detergent with water, preventing decoloration and discoloration, and allows for the use of either liquid or powdered detergent based on user preference, enhancing washing power and minimizing detergent usage.
Implementation Method 1
The liquid detergent container has a protruded siphon and a liquid detergent siphon cover which covers the siphon and provides the water drain passage together with the siphon
Data Source
AI summary
Disclosed herein is a detergent supply apparatus of a washing machine, which installs a liquid detergent container in a powdered detergent chamber of a detergent container. The liquid detergent container makes it possible to mix and supply liquid detergent and water, which allows liquid detergent to be conveniently placed in, moreover, decoloration and discoloration of laundry to be prevented.
