Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ventilated ovens face challenges in reducing energy consumption while maintaining effective air flow, as existing fan and ventilating systems often result in energy waste.
Innovation Solution
An oven panel with a flat portion and a hollow frustoconical body that separates the cooking space from the fan housing, featuring a central opening for fluid flow and a deflector to accelerate and direct air flow, enhancing ventilation efficiency without increasing fan performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the fan and ventilating system performance is increased to generate effective air flow, then ventilation efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent employs a conical deflector with a curved surface that guides air flow smoothly from the cooking chamber toward the fan. This curvature optimizes the flow path, reducing turbulence and energy loss while maintaining effective ventilation, thereby improving productivity without proportionally increasing energy consumption
Solution Approach 2:
The invention changes the physical parameters of air flow by using the conical deflector to accelerate and redirect the air stream. This parameter modification allows the system to achieve better ventilation efficiency with the same fan power, effectively decoupling productivity improvement from energy consumption increase
2Device complexity
If a simple panel design is used to separate cooking space from fan housing, then device complexity is reduced, but ventilation efficiency is insufficient
Solution Approach 1:
The panel is segmented into distinct functional zones: a flat separation portion for isolating the fan housing from the cooking space, and a conical deflector portion for optimizing air flow. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure relatively simple
Solution Approach 2:
The conical deflector acts as an intermediary element between the cooking chamber and the fan. It mediates the air flow by accelerating and directing it toward the fan inlet, enabling efficient ventilation without requiring complex mechanical systems or high-power fans
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 panel design significantly increases ventilation efficiency by accelerating air flow, reducing energy consumption while maintaining effective air circulation, independent of the fan's performance.
Implementation Method 1
The frustoconical body 4 allows a channeling and an acceleration of the air flow from the cooking space towards the fan V
Implementation Method 2
The deflector 6 transversely deflects the air flow that is sucked through the opening 3
