Dishwasher Adsorber Section Layout for Compact Air Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers face space constraints that limit the installation of sufficient dehydrating material for effective air dehydration during the drying phase, as traditional cuboid adsorber areas occupy too much space.
Innovation Solution
The adsorber chamber is divided into multiple sections with dedicated inlet and outlet channels, allowing for a flexible geometry that adapts to available space, ensuring even distribution of dehydrating material and efficient air flow, enabling a compact and efficient dehydration process.

Engineering Contradiction Analysis
1Reliability
If a cuboid adsorber area with sufficient dehydrating material is installed, then adequate air dehydration is achieved, but the space required in the dishwasher is too large
Solution Approach 1:
The adsorber area is divided into multiple adsorber sections (first, second, third sections) with different cross-sectional areas. This segmentation allows the dehydrating material to be distributed in a way that achieves adequate dehydration while reducing the overall volume occupied in the dishwasher.
Solution Approach 2:
The adsorber sections are arranged in different spatial dimensions and orientations within the dishwasher. By utilizing three-dimensional space more efficiently and arranging sections at different heights and positions, the patent achieves sufficient dehydration capacity without requiring a large single-block volume.
2Volume of stationary object
If the adsorber chamber is made compact to fit space constraints, then space utilization improves, but the quantity of dehydrating material may be insufficient
Solution Approach 1:
By dividing the adsorber area into multiple sections with varying cross-sectional areas, the patent concentrates dehydrating material in critical zones (larger cross-sectional areas) while using smaller sections in other areas. This ensures sufficient total quantity of dehydrating material is used effectively without requiring a uniformly large chamber volume.
Solution Approach 2:
Different adsorber sections have different cross-sectional areas tailored to local dehydration requirements. Areas with higher moisture load receive larger adsorber sections with more dehydrating material, while areas with lower moisture load use smaller sections. This localized optimization ensures adequate dehydration throughout while minimizing total material quantity and chamber volume.
3Ease of manufacture
If traditional cuboid adsorber areas are used, then installation is simple, but the geometry does not adapt to cramped space conditions
Solution Approach 1:
The adsorber area is divided into multiple independent adsorber sections that can be manufactured separately and then assembled in the dishwasher. This segmentation provides geometric flexibility to adapt to cramped and irregular space conditions while maintaining relatively simple manufacturing and installation of individual sections.
Solution Approach 2:
The patent creates a flexible, adaptable geometry by using multiple sections that can be arranged in different configurations within the dishwasher. The varying cross-sectional areas and spatial arrangements allow the adsorber chamber to adapt to different space constraints while maintaining a practical installation process.

Function Achieved in This Case
This configuration allows for effective air dehydration in constrained spaces, optimizing the use of available space in dishwashers and ensuring adequate dehydration of air, even in previously inaccessible areas, while maintaining the required amount of dehydrating material.
Implementation Method 1
Zeolites are typically aluminosilicates with the property of being able to adsorb water, among other things. By flowing through the zeolite, the moist air supplied is dried and released again in a dry state.

AI summary
A household appliance has an adsorber area (53) for drying supplied process air (8), in which several adsorber sections are provided (531 - 534). Each adsorber section (531-534) contains an entry surface for the process air to enter and an exit surface for the process air to exit. Entry channels for supplying the process air adjoin at least one of the entry surfaces. Outlet channels for discharging the dried process air each adjoin at least one of the outlet surfaces. Each of the channels is only open on one side, such that the process air is forced from the inlet channels into the adsorber sections and from the adsorber sections into the outlet channels. The intended arrangement of the adsorber sections increases the effective entry area with regard to the dehydrating material, on which the supplied process air meets. This corresponds to a reduction in air resistance through the adsorber area, which in turn can lead to a smaller design of a fan for supplying the process air.
