Rotating Detergent Panel Layout for Stronger Washer Dispensers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry washing machines face issues with the structural integrity and layout of detergent delivery systems, particularly with thin guide means that can break and the need for a water nozzle placement compromise due to the design of the separator panel mechanism.
Innovation Solution
A detergent delivery system featuring a butterfly valve panel that rotates between two configurations, allowing for optimized space usage and improved structural solidity, with a non-hermetically sealed design for efficient detergent release and a robust, cost-effective construction using plastic materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If thin guide means are used to allow separator panel movement, then the device complexity is reduced, but the reliability deteriorates due to breakage risk
Solution Approach 1:
The separator panel is divided into two distinct parts: a movable separator panel for liquid detergent and a fixed partition wall for powder detergent. This segmentation allows the liquid detergent separator to be robust and movable while the powder detergent partition remains fixed and structural, eliminating the reliability issue of thin guides breaking during movement.
2Object-affected harmful factors
If the water nozzle is placed further forward to avoid striking the separator panel, then the harmful factors are reduced, but the device complexity increases due to component crowding
Solution Approach 1:
By dividing the detergent delivery system into separate liquid and powder detergent paths with distinct structural elements (movable separator panel and fixed partition wall), the design allows the water nozzle to be positioned optimally without compromising the separator panel, as the fixed partition wall provides structural support and defines the powder detergent path independently.

AI summary
An electrical household appliance for washing laundry comprises : a washing compartment (2); means (3) for delivering detergent to the washing compartment (2) and comprising a first zone (31) for receiving the detergent introduced from outside the electrical household appliance (1) and a second zone (32), adjacent the first (31) and interposed along the delivery means (3) between the washing compartment (2) and the first zone (31); a panel (4) interposed between the first and the second zone (31, 32), the panel (4) being movable between a first and a second configuration and, in the second configuration, occluding a section (40) for the passage between the first and the second zone (31, 32) which is larger than in the first configuration; the first and second configurations of the panel (4) being suitable for delivering to the washing compartment (2) a powder detergent and a liquid detergent, respectively. According to the invention, the panel (4) is movable rotatably about an axis of rotation (41) oriented substantially according to the physical vertical.
