A flue chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oven-type cooking devices face issues with high-temperature gases damaging the hearth plate due to direct discharge through flue structures, causing color changes and material deterioration in inox raw materials.
Innovation Solution
A flue chamber with an intermediate wall forming a discharge line and insulation element to redirect hot air through a discharge hole, preventing heat transfer to the hearth plate and using a connection section to secure the flue chamber to the cooking device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flue structure directly discharges gases through the body of the cooking device, then gases are effectively removed from the cooking compartment, but the hearth plate surface made of inox raw material undergoes color changes and material deterioration due to high temperature
Solution Approach 1:
The patent introduces a flue chamber as an intermediary component between the cooking compartment and the external environment. This flue chamber includes a discharge line that routes hot gases away from the hearth plate, and an insulation element that acts as a thermal barrier to protect the hearth plate surface from high temperature damage while still allowing effective gas discharge
Solution Approach 2:
The flue structure is segmented into distinct functional zones: a flue outlet section that receives gases from the cooking compartment, a discharge line that transports gases away from sensitive areas, and an insulation element that provides thermal protection. This segmentation allows each component to perform its specific function optimally
2Reliability
If an insulation element is added to protect the hearth plate from heat, then material deterioration is prevented, but the device complexity increases
Solution Approach 1:
The flue chamber integrates multiple functions into a single structural unit: it serves as both the discharge pathway for hot gases and the housing for the insulation element. The insulation element is positioned within the flue chamber structure itself, merging the protective function with the discharge function rather than adding separate components

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively discharges gases without damaging the hearth plate, preventing color changes and material deterioration by blocking heat transfer with insulation, ensuring a durable and reliable solution.
Implementation Method 1
