Removable Grill Oven Chimney Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer ovens are unable to reach high temperatures like commercial ovens, and existing outdoor grill solutions lack efficient heat control and uniformity, leading to uneven cooking.
Innovation Solution
A removable oven for a grill with a high-temperature housing, adjustable cooking plates, and a chimney system that allows for control of heat flow through a perforated diffuser pan and shutter, enabling precise temperature management and even cooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a smaller cooking chamber is used to achieve high temperatures, then temperature control is improved, but heat distribution uniformity deteriorates
Solution Approach 1:
The cooking chamber is segmented into multiple zones with different heating characteristics. The bottom surface has direct radiant heating from the heat source, while the side walls and top provide convective heating. This segmentation allows different parts of the chamber to serve different cooking purposes, with the bottom zone for high-temperature searing and side zones for gentler cooking.
Solution Approach 2:
Different regions of the cooking chamber have different thermal properties. The bottom surface is designed to receive intense radiant heat directly from the source, while the side walls are positioned to capture and distribute heat through convection. This local differentiation of thermal qualities enables precise temperature control in each zone while maintaining overall heat distribution uniformity.
2Ease of operation
If an open cooking chamber is used for ease of accessing food, then operational convenience is improved, but heat retention deteriorates
Solution Approach 1:
A heat reflective barrier is introduced as an intermediary element within the cooking chamber. This barrier reflects radiant heat back into the cooking space, improving heat retention without blocking the open design. The barrier can be positioned to reflect heat from the bottom surface upward, compensating for heat loss through the open chamber structure while maintaining easy access to food.
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 solution provides efficient and cost-effective high-temperature cooking with precise temperature control, ensuring even cooking on both top and bottom surfaces without increasing the cooking surface temperature.
Implementation Method 1
A sliding shutter fixed adjacent to the perforated diffuser pan allows a user to block or alter the flow of heated air through the perforated diffuser pan
Implementation Method 2
A chimney connected to the cooking chamber further controls the heat within the cooking chamber
Implementation Method 3
The cooking plate can be variably positioned above the perforated diffuser pan by at least one adjustable stand thereby altering the distance between the pan
Implementation Method 4
The open bottom of the high temperature housing fits over an adjustable perforated pan disposed between a cooking plate and the cooking grill
