Dishwasher in the form of a commercial utensil washer or dishwasher which is designed as a batch dishwasher
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial batch dishwashers face bottlenecks during busy periods due to longer cycle times required for heavily soiled items, leading to reduced capacity and increased manual workload, as they cannot efficiently handle both lightly and heavily soiled items simultaneously without compromising cleaning performance or resource efficiency.
Innovation Solution
A hood-type or pass-through dishwasher with a treatment chamber divided into two zones, allowing independent treatment of items based on soiling level, with one zone optimized for standard programs and the other for intensive programs, enabling simultaneous processing of differently soiled items without reducing overall capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single treatment zone is used for all items, then the dishwasher structure remains simple, but heavily soiled items require long cycle times that reduce overall capacity during busy periods
Solution Approach 1:
The treatment chamber is divided into two separate treatment zones: a first treatment zone for standard cleaning cycles and a second treatment zone for intensive cleaning cycles. This segmentation allows the dishwasher to process lightly soiled items quickly in the first zone while simultaneously processing heavily soiled items in the second zone, thereby increasing overall capacity without significantly complicating the basic structure.
Solution Approach 2:
Each treatment zone is equipped with its own wash system and control parameters optimized for its specific purpose. The first treatment zone uses standard wash parameters for lightly soiled items, while the second treatment zone employs intensive wash parameters including higher temperatures and stronger spray pressure for heavily soiled items, allowing each zone to operate at optimal efficiency independently.
2Reliability
If intensive cleaning programs are used for heavily soiled items, then cleaning performance is improved, but cycle times increase leading to bottlenecks during busy periods
Solution Approach 1:
By separating the treatment chamber into two zones, the patent enables parallel processing of items with different soiling levels. Lightly soiled items undergo quick standard cleaning in the first zone while heavily soiled items receive intensive cleaning in the second zone simultaneously, eliminating the time bottleneck that would occur if all items had to wait for intensive cleaning cycles.
Solution Approach 2:
The dual-zone configuration allows the dishwasher to maintain continuous productive operation by processing different types of items concurrently. While the second zone performs intensive cleaning for heavily soiled items, the first zone continuously processes lightly soiled items, ensuring that the dishwasher capacity is fully utilized without idle time between cycles.
3Productivity
If the treatment chamber is divided into multiple zones, then different items can be treated simultaneously, but the device complexity and installation space requirements increase
Solution Approach 1:
The second treatment zone is arranged vertically above or below the first treatment zone, utilizing the vertical dimension rather than expanding horizontally. This three-dimensional arrangement allows dual-zone simultaneous processing while maintaining a compact footprint suitable for commercial kitchens with limited installation space.
Solution Approach 2:
Both treatment zones share common infrastructure components including a single wash tank, water supply system, and control unit. This merging of shared resources reduces the overall space requirements and device complexity while still enabling independent operation of each zone for simultaneous processing of different items.
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 enhances the dishwasher's capacity and resource efficiency by allowing continuous operation for lightly soiled items while effectively cleaning heavily soiled items, reducing manual workload and cycle times, and optimizing energy and water usage.
Implementation Method 1
The wash liquid situated in the wash tank can, by way of the wash pump, be delivered via the line system to the wash nozzles
Implementation Method 2
sprayed through the wash nozzles in the treatment chamber onto the items of washware to be cleaned
Implementation Method 3
liquid can flow back from the treatment chamber under the action of gravitational force

AI summary
A batch dishwasher is realized as a hood-type dishwasher having a treatment chamber (2) with at least one recirculating wash system for spraying wash liquid in the treatment chamber (2), and has at least one final rinse system for spraying final rinse liquid in the treatment chamber (2). The treatment chamber (2) has a first treatment zone (6) and at least one further, second treatment zone (7), wherein items of washware can be treated independently of one another and at least temporarily at the same time in the first and in the at least one second treatment zone (6, 7).
