Dishwasher Program Control for Regional Hygiene Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dishwashers are programmed to meet the strictest global hygiene standards, leading to excessive resource consumption in regions with less stringent guidelines, resulting in increased energy, water, and chemical usage.
Innovation Solution
A dishwasher with a control device that stores multiple execution programs, allowing users to select programs tailored to specific regional hygiene standards, optimizing resource usage by varying temperature, liquid quantity, and wash duration based on local requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dishwasher is programmed to meet the strictest global hygiene standards, then hygiene compliance is improved, but resource consumption (energy, water, chemicals) increases
Solution Approach 1:
The dishwasher control device dynamically adapts the execution program based on the selected territorial region. The system switches between different wash parameters (temperature, duration, liquid quantity) depending on the applicable hygiene guidelines, rather than continuously operating at the strictest settings. This dynamic adjustment resolves the contradiction by maintaining high hygiene compliance where required while reducing resource consumption in regions with less stringent standards.
Solution Approach 2:
The invention implements multiple execution programs with different parameter sets (temperature, wash duration, liquid quantity) stored in the control device. Each program is optimized for specific regional hygiene requirements. By changing these parameters based on the selected territorial region, the system achieves compliance with local standards without unnecessarily consuming resources, thus resolving the contradiction between hygiene compliance and resource usage.
2Reliability
If the dishwasher is programmed to meet the strictest global hygiene standards, then hygiene compliance is improved, but water consumption increases
Solution Approach 1:
The system dynamically adjusts water consumption based on the selected territorial region's hygiene requirements. By switching between different execution programs, the dishwasher uses only the necessary amount of water required for compliance with local standards, avoiding excessive water usage in regions with less stringent guidelines while maintaining hygiene compliance where required.
Solution Approach 2:
Different execution programs define different quantities of wash liquid and final-rinse liquid to be sprayed. The control device selects the appropriate program based on the territorial region, thereby changing the water consumption parameter to match local hygiene requirements. This resolves the contradiction by ensuring water usage is sufficient for hygiene compliance but not excessive.
3Reliability
If the dishwasher is programmed to meet the strictest global hygiene standards, then hygiene compliance is improved, but chemical usage increases
Solution Approach 1:
The dishwasher dynamically adjusts chemical usage by selecting different execution programs based on the territorial region. The system adapts the quantity and type of wash liquids and rinse aids used according to local hygiene guidelines, reducing chemical consumption in regions with less stringent standards while maintaining compliance where required.
Solution Approach 2:
The execution programs define different quantities of wash liquid and final-rinse liquid containing chemicals. By changing these parameters based on the selected program, the system optimizes chemical usage to match local hygiene requirements, resolving the contradiction between achieving hygiene compliance and minimizing chemical consumption.
4Adaptability or versatility
If multiple execution programs are stored for different territorial regions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control device is designed with multi-functionality to store and execute multiple execution programs for different territorial regions. A single control device handles diverse hygiene standards through programmable parameters, eliminating the need for multiple specialized devices. This universal design achieves regional adaptability without proportionally increasing device complexity.
Solution Approach 2:
The execution programs are segmented into distinct parameter sets (temperature, duration, liquid quantity) that can be independently configured for different regions. This segmentation allows the control device to manage complexity by organizing regional variations into modular, manageable programs rather than requiring a completely different control system for each region.

AI summary
A dishwasher (2.1, 2.2) has at least one wash system for spraying wash liquid and at least one final-rinse system for spraying final-rinse liquid, wherein a control device (50) is provided for actuating the at least one wash system and/or the at least one final-rinse system in accordance with a predefined execution program. To save on resources during operation, and meet the requirements for hygienic operation, which are defined in hygiene guidelines applicable locally (in a territorially delimited manner) at least a first execution program is stored in the control device (50), the execution program created taking into account requirements for hygienic operation which are applicable in a first territorial region, and at least a second execution program is stored in the control device (50), the second execution program created taking into account requirements for hygienic operation which are applicable in a second territorial region.
