Dishwashing system for cleaning articles to be cleaned comprising at least one cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashing technologies face challenges in efficiently drying items with cavities, particularly bottles, due to the need for manual intervention and the inefficiency of drying cabinets, which are time-consuming and result in uneven drying.
Innovation Solution
A flushing system with a dishwasher and a rinsing basket equipped with nozzles and a pressurization device that applies cleaning fluid and compressed gas separately, allowing for efficient drying of items with cavities without the need for additional equipment or manual handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If items with cavities are cleaned using conventional dishwashing systems, then cleaning of outer surfaces is achieved, but insufficient saturation of inner cavity walls with cleaning fluid results in unreliable cleaning and sanitizing
Solution Approach 1:
The basket is divided into multiple sections with different nozzle configurations. Some baskets have nozzles pointing upward for bottles placed upside down, while others have nozzles pointing in different directions. This segmentation allows each section to be optimized for specific cleaning needs of cavity items, ensuring thorough saturation of inner walls without requiring a single complex universal system
Solution Approach 2:
The nozzle system is integrated within the basket structure itself, with nozzles embedded in the basket walls and base. The bottles are placed inside the basket, creating a nested configuration where the cleaning system (nozzles) is contained within the holding structure (basket), simplifying the overall device while maintaining effective cleaning coverage
2Reliability
If items are dried by turning them upside down and allowing evaporation, then drying of cavity inner walls is achieved, but the process requires interrupting the program and manual intervention which is time-consuming and requires significant personnel resources
Solution Approach 1:
The basket is designed with nozzles positioned to spray cleaning fluid and subsequently drying air directly onto the cavity inner walls during the wash cycle, before the items are removed. This preliminary action saturates the surfaces during cleaning and then facilitates rapid drying without requiring post-cycle manual intervention or program interruption
Solution Approach 2:
The system maintains continuous operation through the entire cycle, with the same nozzle system used for both cleaning fluid application and drying air distribution. The dishwasher continues running without interruption, automatically transitioning from wash to dry phase, eliminating the need for manual intervention and reducing total processing time
3Reliability
If a vacuum blower is used to pump moist air out of cavities during drying, then drying effect is improved, but the equipment complexity and cost increase significantly
Solution Approach 1:
The same nozzle system that delivers cleaning fluid during the wash cycle is also used to distribute drying air during the dry cycle. The nozzles are positioned to effectively deliver both liquid and gas, eliminating the need for separate vacuum blowers or specialized drying equipment while achieving effective cavity drying
Solution Approach 2:
The system uses the dishwasher's own air circulation and heating systems to provide the drying function. The heated air from the dishwasher's normal operation is directed through the nozzles into the cavities, allowing the system to dry items using its own resources without requiring additional vacuum equipment
