Barbecue Grill Hot Plate Venting to Block Oil Drips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barbecue grills face issues with oil drips from meat food causing fires and reducing heating efficiency, as baffles directly on the wire mesh obstruct heat transfer, leading to longer cooking times and higher energy consumption.
Innovation Solution
A barbecue grill design featuring a hot plate covering the heating furnace head with ventilation holes and inclined covering plates that redirect oil away from the heating element while allowing unobstructed airflow, preventing oil from reaching the heating furnace head and maintaining efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a baffle is directly disposed on the barbecue wire mesh to block oil, then oil can be prevented from dropping on the heating furnace head, but the heating efficiency of the heating furnace head is reduced
Solution Approach 1:
The patent introduces a hot plate as an intermediary component between the barbecue wire mesh and the heating furnace head. This hot plate serves as a mediator that blocks oil from reaching the heating furnace head while allowing hot air to pass through its ventilation holes, thus preventing oil contamination without significantly impeding heat transfer to the food
Solution Approach 2:
The hot plate is segmented with multiple ventilation holes distributed across its surface. This segmentation allows the plate to simultaneously perform oil blocking and heat transmission functions - the solid portions block oil while the hole portions allow hot air passage, resolving the contradiction between protection and heating efficiency
2Reliability
If a baffle is directly disposed on the barbecue wire mesh to block oil, then oil stains on the heating furnace head are prevented, but barbecue time is extended and energy consumption increases
Solution Approach 1:
The hot plate acts as an intermediary structure that provides reliable oil protection through its solid surface, while its ventilation holes maintain adequate heat flow. This mediator approach ensures both reliability in oil prevention and efficiency in heat transfer, avoiding extended barbecue times
Solution Approach 2:
The hot plate functions as a porous structure with ventilation holes that allow hot air to pass through while blocking oil. This porous design enables simultaneous achievement of reliable oil protection and maintained heat transfer efficiency, preventing time loss during barbecuing
3Object-affected harmful factors
If a baffle is directly disposed on the barbecue wire mesh to block oil, then oil can be blocked, but the barbecue effect deteriorates
Solution Approach 1:
The hot plate serves as an intermediary that blocks oil effectively while its ventilation holes preserve heat flow to the food. This mediator structure maintains effective barbecue conditions by preventing oil interference with the heating process while ensuring adequate heat reaches the food for proper cooking
4Object-affected harmful factors
If a hot plate with covering plates is used to block oil, then oil is redirected away from the heating furnace head, but the structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into a single integrated hot plate structure. The plate combines oil blocking, heat transmission, and oil redirection capabilities in one component, replacing what would otherwise require multiple separate parts. This merging approach achieves effective oil redirection while minimizing structural complexity
