Dishwasher Entry Trough Cleaning With Rotating Washing Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor-type dishwashers face inefficiencies in cleaning the trough base at the entry point due to the limitations of traditional covering sieves, which fail to collect larger dirt particles and require frequent cleaning, leading to increased operational costs and downtime.
Innovation Solution
A system where a washing container collects water and pours it in a high-energy gush onto the inclined trough base, directing food residues and waste towards a dirt-collecting sieve, eliminating the need for covering sieves by using a rotatable container that shifts its center of gravity to empty and refill, ensuring continuous cleaning without interrupting the rinsing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If covering sieves are used to collect dirt on the trough base, then dirt collection is provided, but larger dirt particles cannot be collected and frequent cleaning is required
Solution Approach 1:
The washing container performs preliminary cleaning action by pouring water onto the trough base before the items reach the dirt-collecting sieve, preventing large dirt particles from accumulating on the trough base in the first place
Solution Approach 2:
The washing container acts as an intermediary device between the loading zone and the dirt-collecting sieve, using water as a mediator to wash away dirt particles before they can interfere with the normal operation of the covering sieve
2Reliability
If covering sieves are used to collect dirt, then dirt collection is provided, but the sieves require manual removal and cleaning, increasing operational costs
Solution Approach 1:
The washing container performs self-service by automatically filling with water, positioning itself, and pouring the water onto the trough base without requiring manual intervention, thereby eliminating the need for manual sieve cleaning
Solution Approach 2:
The washing container operates periodically by filling with water, positioning itself at the pouring location, emptying its contents onto the trough base, and then returning to the filling position, creating a continuous self-cleaning cycle
3Productivity
If a washing container pours water in a gush onto the trough base, then food residues are washed away effectively, but water consumption increases
Solution Approach 1:
The washing container changes the parameters of water delivery by controlling the pouring height and flow rate to create a high-energy gush that maximizes cleaning efficiency while minimizing the total volume of water required
Solution Approach 2:
The washing container uses periodic action by filling and emptying in cycles, allowing the same water to be used multiple times for cleaning different sections of the trough base, thereby reducing overall water consumption
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 effectively washes away both small and large food residues and waste along the trough base's gradient, reducing the need for covering sieves, lowering operational costs, and minimizing downtime by allowing continuous cleaning without the need for manual sieve removal and cleaning.
Implementation Method 1
A washing container (18) is arranged within the entry region (10) and is filled with a stock of fluid, in particular water, which is regularly poured out in the manner of a gush
Implementation Method 2
The washing container (18) is fitted in such a manner that it can be removed in a simple manner with just a few actions and can be cleaned in a simple manner

AI summary
The invention relates to an entry region of a conveyor-type dishwasher. A conveyor belt which moves in the conveying direction is located in the entry region. The entry region comprises a trough base which is bounded by sidewalls arranged laterally. The entry region contains at least one washing container which stores a stock of fluid and, upon emptying, cleans the trough base.
