Dishwasher External Drain Hose Routing to Reduce Assembly Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-carrying household appliances, such as dishwashers, face challenges in managing the drain hose to prevent unintended water leakage and require complex hose guides and additional components, which complicate assembly and increase costs.
Innovation Solution
A water-carrying household appliance with a first and second holding device on its outer wall to securely hold the drain hose, allowing it to be routed externally and eliminating the need for additional components like risers, while providing flexibility in placement and protection from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex hose guide with additional components is used to route the drain hose, then the hose can be securely held and water leakage is prevented, but the assembly process becomes more complex and costs increase
Solution Approach 1:
The patent combines the hose guide function directly into the rear wall structure of the washing machine. The rear wall includes an integrated guide channel that routes the drain hose from the pump to the discharge point, eliminating the need for separate hose guide components. This integration maintains reliable hose routing while simplifying the overall device structure and reducing assembly complexity.
2Ease of operation
If additional components like risers are used to route the hose, then proper hose positioning is achieved, but manufacturing costs and assembly complexity increase
Solution Approach 1:
The guide channel for the drain hose is integrated directly into the rear wall structure of the washing machine. This eliminates the need for separate riser components or additional hose routing accessories. The rear wall itself provides the necessary structural support and routing path, simplifying manufacturing while maintaining proper hose positioning and flexibility.
3Object-affected harmful factors
If the hose is routed internally within the appliance, then it is protected from damage, but the appliance dimensions increase and assembly becomes more complex
Solution Approach 1:
The drain hose is routed externally along the rear wall of the washing machine rather than being completely enclosed within the appliance body. The hose follows the outer contour of the rear wall, which provides protection from damage while maintaining compact appliance dimensions. This external routing along the rear wall avoids the need for additional internal space.
