Pellet grill with open flame switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional barbecue grills using charcoal or coke generate soot, coal slag, and ash, posing appearance, taste, and safety issues, with combustibles being difficult to extinguish and requiring cumbersome clearing.
Innovation Solution
A pellet grill with an open flame switch featuring a housing, pellet bin, burning bin, oil baffle, and open flame baffle, where the open flame baffle can be moved to block or allow flame outlet grooves, facilitated by a stirring rod and top cover mechanism, allowing for easy flame control and ash collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If charcoal or coke is used as fuel for barbecue, then the barbecue can be conducted, but soot, coal slag and coal ash are generated which affect appearance and taste of food
Solution Approach 1:
The patent changes the fuel type from charcoal/coke to wood pellets, which fundamentally alters the combustion characteristics and reduces harmful emissions. This parameter change in fuel composition and form factor eliminates soot and coal slag generation while maintaining barbecue functionality
Solution Approach 2:
The patent employs disposable wood pellets as fuel, which are designed for single-use combustion. These pellets burn completely and leave minimal residue, eliminating the need for clearing coal ash and slag while maintaining ease of operation through simple fuel replacement
2Ease of operation
If combustibles are placed directly with flames not shielded and unattended, then barbecue can be conducted, but potential safety hazards are likely to occur
Solution Approach 1:
The patent introduces a shield structure as an intermediary between the flame source and the surrounding environment. This shield contains and directs the flames, preventing uncontrolled fire spread while allowing barbecue operations to proceed normally. The shield acts as a safety mediator that reconciles open flame operation with fire safety
3Object-generated harmful factors
If combustibles are poured out to be doused after or during barbecue, then flames can be extinguished, but it is troublesome and brings inconvenience due to subsequent clearing
Solution Approach 1:
The patent extracts the combustion process from direct exposure by containing it within a shielded chamber. The flames are confined and controlled within the shield structure, allowing easy extinguishment by simply closing the shield or cutting off fuel supply, without requiring pouring out or dousing operations. This extraction of the flame into a controlled environment eliminates the troublesome clearing process
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 design enhances cleaning convenience, improves food taste by controlled flame exposure, and increases safety by blocking flames when not in use, reducing the risk of fires and sparks.
Implementation Method 1
the open flame baffle may be moved so as to close and open the flame outlet grooves
Implementation Method 2
the open flame baffle may be driven to move by moving the stirring rod
Implementation Method 3
in the case that the top cover is in a closed state, the push block abuts against the stirring rod, and the open flame baffle closes the flame outlet grooves
Implementation Method 4
one end, away from the stirring rod, of the open flame baffle is provided with a limiting portion horizontally extending outwards, one end of the oil baffle is provided with a positioning portion, and the positioning portion is adaptive to the limiting portion
Implementation Method 5
two sides of the open flame baffle are provided with limiting slideways, the oil baffle is provided with raised limiting ribs, and the limiting ribs are adaptive to the limiting slideways
Implementation Method 6
the open flame baffle includes flame blocking portions, the flame blocking portions are adaptive to the flame outlet grooves, and the flame blocking portions may completely cover the flame outlet grooves
Implementation Method 7
the open flame baffle is provided with open flame grooves, and the open flame grooves are positioned between the adjacent flame blocking portions
