Solution Overview
Problem
Existing kitchen appliances, such as automatic rice cookers, face challenges in efficiently and sanitarily cleaning materials due to the combined function of material feeding and air supply, which complicates the product layout and limits the selection of feeding power sources and air source positioning.
Innovation Solution
A material cleaning device with a cleaning cavity featuring a separate material feeding port and air inlet, connected to a transport pipe and a cleaning inlet pipe that can move up and down, utilizing a three-way joint for air and water flow to facilitate automatic feeding and discharging, and a cleaning and sealing assembly that uses air flow for stirring and water for cleaning, while also serving as a discharge valve to simplify the structure and improve integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the material feeding port and air inlet are combined into one component, then the device complexity is reduced, but the adaptability of power source selection and air source positioning is limited
Solution Approach 1:
The patent divides the combined feeding and air supply function into separate components: a material feeding port for transporting materials and a separate air inlet for supplying air flow. This segmentation allows independent optimization of each component and enables greater flexibility in selecting power sources and positioning air sources within the cooking appliance.
2Device complexity
If the cleaning and sealing assembly is integrated at the material discharging port, then the device complexity is reduced and product volume is minimized, but the reliability of sealing and discharge control may be compromised
Solution Approach 1:
The patent integrates the cleaning assembly and sealing assembly into a unified component structure positioned at the material discharging port. The cleaning inlet pipe serves dual purposes: supplying cleaning fluid and acting as a sealing element. This merging reduces the number of separate components while maintaining effective sealing and discharge control through the coordinated design of the cleaning and sealing functions.
3Device complexity
If air flow is used for material discharging instead of mechanical means, then the device complexity is reduced and ease of operation is improved, but the force available for material transport is limited
Solution Approach 1:
The patent employs pneumatic principles by using air flow generated through the air inlet to transport materials from the cleaning cavity through the material discharging port. The air flow creates sufficient force to move lightweight materials such as rice without requiring complex mechanical discharge mechanisms, thereby simplifying the overall device structure while maintaining effective material transport capability.
