Rotating Distributor Disk for Cooking Chamber Cleaning Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances face challenges in effectively and efficiently cleaning the cooking chamber with conventional methods, which often result in incomplete cleaning and excessive resource consumption.
Innovation Solution
A cooking appliance equipped with a distributor disk that can be driven by its own drive or the power of the cleaning liquid, featuring a base plate and vanes arranged at specific angles to target cleaning liquid application, and a reversible pump for efficient circulation and backwashing, allowing for varied rotational speeds and pulsating cleaning patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cleaning methods are used, then the cleaning process is simple, but the cleaning effectiveness is insufficient and resource consumption is excessive
Solution Approach 1:
The distributor disk is designed to rotate dynamically, transforming from a static cleaning approach to a dynamic one. The rotation speed can be varied to optimize cleaning effectiveness for different soiling levels, while the rotating distribution pattern ensures comprehensive coverage with reduced liquid consumption compared to continuous spraying
Solution Approach 2:
The system implements periodic action through the rotating distributor disk that intermittently applies cleaning liquid to different areas of the cooking chamber. This periodic distribution pattern allows cleaning liquid to be applied only when needed to specific zones, reducing overall consumption while maintaining effectiveness
2Adaptability or versatility
If a fixed distributor system is used, then the device complexity is low, but the adaptability to different cleaning needs is poor
Solution Approach 1:
The distributor disk rotation mechanism provides adaptability by allowing the system to switch from static to dynamic operation. The variable rotation speed capability enables adaptation to different cleaning requirements without adding complex control systems
Solution Approach 2:
The distributor disk can be driven automatically by the cleaning liquid flow itself or by a simple drive mechanism, reducing the need for complex external control systems while maintaining versatility in cleaning applications
3Productivity
If high rotational speed is used for thorough cleaning, then the cleaning coverage is improved, but the energy consumption and noise increase
Solution Approach 1:
The rotating distributor disk provides thorough cleaning coverage through its rotation, but at variable speeds. By using periodic rotation rather than continuous high-speed operation, the system achieves comprehensive coverage while minimizing energy consumption and noise generation during the cleaning cycle

Implementation Method 2
a pump (16) which can promote the cleaning liquid in a circulation direction
Implementation Method 3
the pump (16) is designed and arranged in such a way that when the pump (16) is switched off, the cleaning liquid can flow back from the inlet line (20), the pump (16) and the outlet line (18) in the direction of the process (22) counter to the direction of circulation of the circulation system (14) by means of gravity
