Washer Detergent Flow Path With Trap and Hidden Water Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treatment machines face challenges in simplifying the assembly of detergent flow paths, preventing leakage, minimizing water discharge from traps due to pressure changes, and hiding water flow from the user's view when the door is opened.
Innovation Solution
The apparatus features a detergent flow path with a water trap and decelerating walls to slow down water flow, guiding it back into the cabinet, and an insulating part connecting the tub and cabinet to manage pressure changes, ensuring the water is not externally visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detergent flow path is fixed to the detergent storage part and tub through clamps, then the connection is secure, but the assembly time is considerable and complex
Solution Approach 1:
The detergent flow path is integrated with the detergent storage part through a unified structure where the flow path forms an integral part of the storage assembly, eliminating the need for separate clamp fasteners and reducing assembly steps while maintaining secure connection
Solution Approach 2:
The detergent storage part is divided into modular components that can be easily assembled and disassembled without complex fastening mechanisms, allowing quick assembly while ensuring reliable connections through simplified interface designs
2Object-generated harmful factors
If the trap interrupts the connection between tub and detergent storage part, then foam discharge is prevented, but water stored in the trap discharges into the tub when door opens causing user doubt
Solution Approach 1:
A check valve is introduced as an intermediary component in the detergent flow path that allows controlled water flow while preventing unwanted discharge, mediating between the trap and tub to eliminate the harmful effect of water discharge when door opens
Solution Approach 2:
The harmful effect of water discharge is extracted and redirected to a separate drainage path, isolating it from the main detergent flow path and preventing user doubt while maintaining the foam interruption function
3Speed
If water flows quickly from the trap to the tub, then the flow path is clear, but the water discharge is visible and causes user concern
Solution Approach 1:
A guide structure acts as an intermediary that redirects water flow along the inner wall of the detergent storage part, preventing direct visible discharge into the tub while maintaining efficient water movement through the system
