Innovation Solution
A high-pressure cleaning system utilizing an orbital head with rotating nozzles that can be driven by either water pressure or a separate motor, allowing for thorough and efficient cleaning without the need for continuous wetting and extensive chemical use, combined with a heating mechanism for drying and disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning with hand shower is used, then the cooking chamber can be cleaned, but the process requires a lot of labor and consumes large amounts of water and detergent
Solution Approach 1:
The cleaning system performs automatic cleaning of the cooking chamber without requiring manual operation. The control unit automatically controls the cleaning liquid supply, circulation pump, spray nozzles, and heating element to clean the cooking chamber, eliminating the need for manual cleaning operations and associated resource consumption.
Solution Approach 2:
The system uses a circulation pump to circulate cleaning liquid through spray nozzles that distribute the cleaning solution uniformly across the cooking chamber surfaces. The hydraulic system enables automated cleaning with controlled fluid flow, reducing both labor and resource consumption compared to manual methods.
2Reliability
If circulation system with concentrated cleaner is used, then excellent cleaning effect can be achieved, but the system is unsuitable for trough-shaped cooking spaces without additional filtering and distribution assemblies
Solution Approach 1:
The cleaning system is designed to be universally applicable to different cooking chamber shapes including trough-shaped chambers. The spray nozzles are positioned to distribute cleaning liquid uniformly across all surfaces, and the circulation pump handles the entire volume, making the system adaptable to various geometries without requiring shape-specific modifications.
Solution Approach 2:
The cleaning system divides the cooking chamber into multiple spray zones covered by different nozzles. The circulation pump segments the cleaning liquid flow into multiple streams that reach different areas, ensuring complete coverage of complex geometries without requiring a separate system for each chamber shape.
3Manufacturing precision
If fan wheel is used to distribute washing liquor, then even distribution can be achieved, but the system cannot be applied to cooking appliances without such components
Solution Approach 1:
The system uses spray nozzles as intermediary devices to distribute cleaning liquid uniformly across the cooking chamber. Instead of relying on a fan wheel, the nozzles act as intermediaries that convert pump pressure into distributed spray patterns, achieving uniform coverage without requiring rotating components or specific appliance features.
Solution Approach 2:
The system replaces the mechanical fan wheel distribution mechanism with a stationary spray nozzle system driven by hydraulic pressure. This substitution eliminates the need for rotating mechanical components and makes the system compatible with various appliance types regardless of whether they have fan wheels or not.
4Productivity
If high-pressure device with rotatable head is used, then rapid and reliable cleaning can be achieved, but the system requires high-pressure liquid supply infrastructure
Solution Approach 1:
The system merges the high-pressure cleaning function with the existing cooking appliance structure. The circulation pump, which is already part of the appliance for other functions, is used to generate the high-pressure spray, and the spray nozzles are integrated into the cooking chamber. This combination eliminates the need for separate high-pressure infrastructure while achieving rapid cleaning.
Solution Approach 2:
The circulation pump is designed to serve multiple functions: it circulates cleaning liquid during automatic cleaning cycles and can also function as part of the cooking appliance's liquid handling system during normal operation. This multi-functionality reduces infrastructure requirements by utilizing existing components for multiple purposes.
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 system provides a rapid, reliable, and labor-saving cleaning process that reduces water and detergent consumption, effectively cleaning all areas of the cooking chamber with minimal manual intervention and optional use of cleaning concentrates, optimizing cleaning time and energy usage.
Implementation Method 1
a liquid jet under high pressure from a rotatable head with at least one nozzle opening is supplied into the cooking chamber from behind the rear wall in order to mechanically remove substances from the walls, the bottom and the inside of the lid
Implementation Method 2
combined with a heating mechanism for drying and disinfection

AI summary
The invention relates to a cooking device having a cooking chamber (16) in an interior of a pan (10) and comprising a closable lid (20). The pan (10) also has a drain (30) and a cleaning assembly (40) for feeding cleaning liquid into the pan (10). The cleaning assembly (40) has a high-pressure device for introducing the cleaning liquid into the pan at high pressure. The cleaning assembly is guided into the cooking chamber (16) inside the pan (10) through a wall (12) of the pan (10). The cleaning assembly has a rotatable head (41) having one or more nozzle openings (42) for the cleaning liquid. The rotatable head (41) having one or more nozzle openings (42) is designed and arranged in such a way that the flowing cleaning liquid fed by means of the high-pressure device exerts a mechanical force that causes the head (41) to rotate. Alternatively, a motor can apply said force.
