Wash arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial dishwashers require extensive manual effort for cleaning at the end of each working day, involving multiple steps and resources, which can be inefficient and labor-intensive.
Innovation Solution
A wash arm with integrated cleaning openings and an automatic opening/closing mechanism that allows for automated rinsing, reducing the need for manual intervention and minimizing cleaning and maintenance operations by ensuring efficient rinsing and drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning procedures are used for wash arms and screen systems, then thorough cleaning can be achieved, but significant labor time and resources are required
Solution Approach 1:
The wash arm is equipped with an integrated cleaning opening that allows the system to clean itself automatically. During the wash cycle, cleaning liquid is supplied through the cleaning opening to rinse the interior of the wash arm, eliminating the need for manual disassembly and cleaning operations while maintaining thorough cleaning effectiveness
Solution Approach 2:
The cleaning opening enables preliminary rinsing action to be performed during the wash cycle itself, before manual cleaning would normally occur. This preliminary automated rinsing removes loose dirt and debris, reducing the subsequent manual cleaning effort and time required
2Reliability
If wash arms are disassembled for cleaning, then internal tubes can be flushed, but the cleaning process becomes more complex and time-consuming
Solution Approach 1:
The cleaning opening is positioned and designed to allow cleaning liquid to flow through the internal tubes of the wash arm without requiring disassembly. The system performs its own internal tube flushing through this integrated opening, maintaining cleaning completeness while eliminating the need for complex disassembly procedures
Solution Approach 2:
The cleaning opening serves multiple functions: it allows rinsing of the wash arm interior, flushing of internal tubes, and drainage of cleaning liquid. This multi-functionality consolidates what would otherwise require multiple separate cleaning operations and disassembly steps into a single integrated process
3Extent of automation
If cleaning openings are provided at end regions of wash arm housing, then automated rinsing is enabled, but the structure becomes more complex
Solution Approach 1:
The cleaning opening is positioned at the end region of the wash arm housing, segmenting the cleaning function from the main wash arm structure. This allows the cleaning function to be added as a discrete feature rather than integrating complexity throughout the entire structure, enabling automated rinsing with minimal structural modification
Solution Approach 2:
The cleaning opening acts as an intermediary interface between the automated rinsing system and the wash arm interior. This single opening mediates the complex task of internal cleaning by providing a controlled access point for cleaning liquid supply and drainage, simplifying the overall system architecture
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 automated wash arm system significantly reduces the time and resources required for cleaning, prevents clogging, and enhances the efficiency of the dishwashing process by allowing thorough rinsing and rapid drainage, thereby improving the overall cleaning result and extending the intervals between maintenance checks.
Implementation Method 1
washing liquid which can be sprayed by the spray nozzles in the treatment chamber onto the washware to be cleaned. The sprayed washing liquid then flows back into the wash tank
