Dishwasher Door Guide Structure to Redirect Drying Fluid onto Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwashers with front doors often have a free space or peripheral gap between the inner door wall and washing baskets, which limits the effectiveness of the drying fluid in absorbing moisture from items, as the drying fluid flow primarily follows the heightwise direction and does not adequately contact the items for washing.
Innovation Solution
A guide structure comprising multiple guide elements projecting from the inner face of the door, which redirects the drying fluid flow horizontally into the washing compartment, ensuring better contact with items by diverting the flow away from the door and onto the items, thereby improving drying performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a free space or peripheral gap is present between the inner door wall and washing baskets, then the door structure is simple and easy to manufacture, but the drying fluid flow does not adequately contact the items for washing, reducing drying effectiveness
Solution Approach 1:
The guide structure acts as an intermediary element between the drying fluid flow and the washing baskets. It redirects the fluid that would otherwise flow harmlessly along the door to instead contact the items for washing, thereby improving drying effectiveness without complicating the door structure itself
Solution Approach 2:
The guide structure utilizes the existing drying fluid flow and redirects it to serve the drying function more effectively. The system makes the existing fluid flow work for itself by directing it onto the washing baskets, improving drying performance without requiring additional energy input or complex mechanical systems
2Device complexity
If the drying fluid flow follows the heightwise direction along the inner face of the door, then the flow path is simple, but the drying fluid contacts the items for washing only to a limited degree, reducing moisture absorption
Solution Approach 1:
The guide structure redirects the drying fluid flow from a purely vertical (heightwise) path to include a horizontal component directed toward the washing baskets. This dimensional change in flow direction enables the fluid to contact the items for washing more effectively, increasing moisture absorption capacity
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 guide structure enhances the drying efficiency by ensuring that the drying fluid effectively reaches and absorbs moisture from items, leading to improved drying results, especially for upper baskets, by redirecting the flow and utilizing previously unused portions of the drying fluid.
Implementation Method 1
at least one guide structure, in particular in the form of a number or plurality of individual guide elements, projects in a raised manner from an essentially planar or flat surface of its door inner face and is disposed in such a manner that when the dishwasher is in drying mode a drying fluid flowing along the inner face of the door is guided to a washing basket accommodated in the interior of the washing compartment or onto items for washing disposed thereon
Implementation Method 2
drying fluid in the form of air is made to flow so that it flows around the items for washing, thereby absorbing moisture and releasing said moisture again at a different point

AI summary
A dishwasher, in particular a domestic dishwasher, including a washing compartment, at least one washing basket disposed in the washing compartment to hold items for washing, and a door configured to close the washing compartment. The door has a planar surface to form an inner face of the door as a whole or a part thereof. When the door is closed, a guide structure including a plurality of individual guide elements projects in a raised manner from the planar surface into an interior of the washing compartment and is disposed so as to guide a drying fluid flowing along the inner face of the door onto the items in the washing compartment, when the dishwasher is in drying mode.
