Solution Overview
Problem
Existing dishwasher sorption drying systems face challenges in adequately and efficiently drying reversibly dehydratable sorption material, leading to incomplete drying and potential overheating during the desorption process.
Innovation Solution
A dishwasher design featuring a pot-shaped sorption container with a cover part connected via a mechanical flanged or clinch connection, allowing for proper air flow and efficient drying during the sorption process, and gentle regeneration during desorption, ensuring reliable and energy-efficient drying and regeneration of the sorption material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If a heater is arranged in front of the sorption column to heat air during desorption, then the sorption material can be regenerated, but local overheating of the dry material occurs during the desorption process
Solution Approach 1:
The housing is divided into a cup-shaped housing part and a cover part that are connected by a mechanical connection rather than being permanently fixed. This segmentation allows for controlled air flow paths and heat distribution during desorption, preventing localized overheating while maintaining regeneration efficiency
Solution Approach 2:
The mechanical connection between the cover part and cup-shaped housing part allows the housing to adapt dynamically during different operational phases (sorption vs. desorption). During desorption, this dynamic structure enables optimized air flow and heat distribution to prevent overheating while maintaining effective regeneration
2Stability of the object's composition
If the sorption column housing is permanently fixed, then structural stability is maintained, but compact accommodation and proper air flow are compromised
Solution Approach 1:
The housing is segmented into a cup-shaped housing part and a cover part connected by a mechanical connection. This segmentation enables compact accommodation within the dishwasher while maintaining structural stability during operation. The modular design allows for space-efficient integration without compromising the integrity of the sorption column
3Strength
If the sorption column housing is permanently fixed, then structural integrity is maintained, but proper air flow for drying and regeneration is restricted
Solution Approach 1:
The mechanical connection between the cover part and cup-shaped housing part creates a dynamic structure that optimizes air flow during both drying and regeneration phases. This dynamic design maintains structural integrity while enabling efficient air circulation through the sorption material, improving both drying performance and regeneration efficiency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures thorough drying of items and efficient regeneration of the sorption material, preventing overheating and improving the overall drying performance while maintaining energy efficiency.
Implementation Method 1
a sorption drying system having at least one sorption compartment with reversibly dehydratable sorption material, which is connected to the washing compartment via at least one air duct to generate an air flow
Implementation Method 2
For regeneration, i.e. desorption of the sorption column, its reversibly dehydratable dry material is heated to very high temperatures. Water stored in this material escapes as hot water vapor
