Dishwasher Storage Container Flow Duct for Dirt Flushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water-bearing domestic appliances, such as dishwashers, face challenges in reducing water consumption and effectively removing contaminants like fatty films and particles from storage containers, which can lead to odor and hygiene issues due to reduced process temperatures.
Innovation Solution
Incorporating at least one flow control element in the liquid chamber of the storage container to create a controlled flow that diverts and flushes washing liquor, ensuring all areas are subjected to flow and preventing the congregation of dirt, combined with heating the washing liquor to break down deposits, and using flow control elements to define a flow duct that follows the internal panel contours for targeted cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If storage container is used for temporary storage of washing liquor, then water consumption is reduced, but soiling in the form of fatty film and particles of dirt becomes lodged in the storage container
Solution Approach 1:
The flow control element ensures continuous flow of washing liquor through the storage container during filling, emptying, and flushing operations. This continuous flow prevents stagnation and eliminates flow-free zones where dirt and fatty films could accumulate, thereby maintaining cleanliness while enabling water reuse
Solution Approach 2:
The flow control element extracts and removes contaminants (particles of dirt and fatty films) from the washing liquor by maintaining active flow through the storage container. This prevents conglomeration of particles and eliminates odor and hygiene problems while allowing the storage container to fulfill its water-saving function
2Productivity
If flow control element is added to create controlled flow, then cleaning efficiency is enhanced, but device complexity increases
Solution Approach 1:
The flow control element segments the washing liquor flow into controlled paths within the storage container. By dividing the flow into specific trajectories, it ensures all areas of the container are subjected to flow, preventing stagnation zones and enhancing cleaning efficiency without requiring complex mechanical systems
Solution Approach 2:
The flow control element acts as an intermediary component that mediates between the inlet and outlet of the storage container. It creates a flow duct that guides the washing liquor through the container interior, ensuring comprehensive coverage and effective contaminant removal while maintaining a simple structural design
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
This solution significantly enhances cleaning efficiency by removing dirt mechanically and thermally breaking down deposits, preventing odor and hygiene issues, and ensuring consistent flushing of the storage container, thereby improving the appliance's operational performance.
Implementation Method 1
at least one flow control element in the liquid chamber of the storage container to divert and/or to divide the washing liquor flowing into or being discharged from the storage container
Implementation Method 2
heating the washing liquor fed into the storage container to a temperature of a magnitude of 60 to 75° C., whereby deposits of fat are broken down thermally
Implementation Method 3
the speed of flow can be selected in such a way that the particles of dirt which have become attached to the inside of the storage container can be removed mechanically by the flow of liquid

AI summary
A water-bearing domestic appliance, in particular a dishwasher, includes a liquid storage container, in particular a storage container in which washing liquid can be temporarily stored. At least one flow-control element is arranged in a liquid chamber of the storage container to divert and/or to split the washing liquor flowing into the storage container or being discharged from it.
