Barbecue Grill Hot Plate Venting to Prevent Oil Flare-Ups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior barbecue grills face issues with oil drips from meat food causing fires and reducing heating efficiency due to baffles directly on the wire mesh, leading to poor barbecue quality and increased energy consumption.
Innovation Solution
A barbecue grill design featuring a hot plate with inclined surfaces and ventilation holes, positioned above the heating furnace head to catch oil drips and allow hot air passage, while maintaining efficient heating without obstructing food placement.
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 reaching the heating furnace head, but the heating efficiency is reduced and energy consumption increases
Solution Approach 1:
A hot plate is introduced as an intermediary component between the barbecue wire mesh and the heating furnace head. The hot plate serves dual functions: it blocks oil from reaching the heating furnace head while simultaneously allowing hot air to pass through its ventilation holes to heat the food, thus preventing energy loss
Solution Approach 2:
The hot plate performs multiple functions simultaneously: it acts as an oil barrier, a support structure for the barbecue wire mesh, and a heat transfer medium that allows hot air circulation through its ventilation holes. This multi-functionality resolves the contradiction by eliminating the need for separate oil-blocking and heating components
2Object-affected harmful factors
If a baffle is directly disposed on the barbecue wire mesh to block oil, then oil can be prevented from reaching the heating furnace head, but the barbecue effect deteriorates
Solution Approach 1:
The hot plate serves as an intermediary that blocks oil while maintaining heat flow. Its ventilation holes allow hot air to pass through effectively, ensuring that the barbecue process remains efficient while preventing oil contamination of the heating furnace head
Solution Approach 2:
The hot plate features localized ventilation holes distributed across its surface, creating areas of different functionality: solid regions block oil while the hole regions allow hot air passage. This local differentiation enables simultaneous oil blocking and efficient heat transfer

AI summary
The present invention relates to a barbecue grill (1) including a barbecue grill body (103) having a cavity (1031) with an opening in an upper end, a heating furnace head (109) and a hot plate (108) are disposed in the cavity, and a barbecue wire mesh (110) is disposed on the opening of the cavity, the hot plate covers the whole top of the heating furnace head and is provided with a plurality of ventilation holes, and an upper surface of the hot plate is inclined and is provided with a plurality of covering plates (1082) on the positions corresponding to the ventilation holes, each covering plate covers the whole top of the ventilation hole, one end of the covering plate is connected to an upper surface of the hot plate and the other end extends slantwise downwards and a gap is disposed between the upper surface of the hot plate and the other end of the covering plate. The hot plate is disposed in the cavity and covering the whole top of the heating furnace head, which avoids the oil generated by the meat food dropping on the heating furnace head and generating a fire. The hot plate is far away from the barbecue wire mesh, such that it doesn't block out the food and doesn't affect the heating of the food on the barbecue wire mesh. Therefore the heating efficiency is high and the barbecue efficiency is good.
