Dishwasher Operating Panel Spray Integration for Simpler Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashers require significant manufacturing effort due to separate spray devices integrated in the washing compartment, necessitating additional openings and liquid supply lines in the walls.
Innovation Solution
Integrate spray devices into existing operating components, such as the wall or lid of the washing compartment, utilizing existing openings for both functionality and cleaning liquid supply, eliminating the need for separate installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spray devices are integrated as separate components in the washing compartment, then cleaning effectiveness is improved, but manufacturing complexity and effort increase significantly
Solution Approach 1:
The spray device is merged with the operating device by integrating the spray nozzle directly into the operating device housing. The operating device serves dual functions: controlling the dishwasher operation and housing the spray nozzle that directs cleaning liquid onto the dishes. This eliminates the need for separate spray device components and their associated mounting openings and liquid supply lines.
Solution Approach 2:
The operating device is given multiple functions: it serves as both the control interface for the dishwasher and as the housing for the spray device. The same opening in the washing compartment wall that accommodates the operating device also serves as the mounting location for the spray nozzle, eliminating the need for separate openings and simplifying manufacturing.
2Ease of operation
If separate openings and liquid supply lines are provided for spray devices, then spray functionality is achieved, but manufacturing effort and cost increase
Solution Approach 1:
The liquid supply line for the spray device is merged with the existing liquid supply system of the dishwasher. The spray nozzle is connected to the cleaning liquid supply through the same piping that supplies the main washing chamber, eliminating the need for separate liquid supply lines and reducing manufacturing complexity.
Solution Approach 2:
The existing opening in the washing compartment wall, designed for the operating device, is made multi-functional by also serving as the mounting opening for the spray nozzle. This eliminates the need for additional openings and simplifies the manufacturing process while maintaining full spray functionality.
