Latch Plate Shield Airflow Layout for Built-In Double Ovens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Built-in double ovens require effective cooling air and exhaust air flow arrangements to maintain selected cooking temperatures and prevent heat-related damage to components, while existing solutions face challenges in efficiently guiding exhaust air away from electrical wiring and ensuring adequate cooling of oven components.
Innovation Solution
An integrated cooling air and exhaust air flow arrangement featuring a first air guiding path for combining cooling and exhausted air from both ovens, a second air guiding path for guiding air from the lower oven, and a latch plate shield that directs heated air into a mid-channel to mix with cooling air, promoting efficient heat dissipation and cooling of the double oven combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If built-in double ovens are installed in close proximity with one oven above the other, then space utilization is improved and heat retention is enhanced, but effective guidance of cooling air and exhaust air becomes difficult and heat dissipation is compromised
Solution Approach 1:
The air flow arrangement is segmented into multiple distinct paths: a first air guiding path for the upper oven that directs cooling air downward and exhaust air laterally, and a second air guiding path for the lower oven that directs cooling air laterally and exhaust air downward. This segmentation prevents heat accumulation between the ovens while maintaining compact installation.
Solution Approach 2:
The air flow paths utilize three-dimensional space by directing air flows in multiple directions (downward, lateral, upward) rather than simply horizontal or vertical flows. The first air guiding path directs cooling air downward from the upper oven while the second path directs cooling air laterally at the lower oven, creating a multi-dimensional air circulation pattern that effectively cools both ovens in close proximity.
2Loss of energy
If ovens are positioned closely together to reinforce heat retention, then energy consumption is reduced, but guidance of exhaust air away from electrical wiring and components becomes challenging
Solution Approach 1:
The exhaust air flows are extracted and directed along separate paths from the cooling air flows. The first air guiding path extracts exhaust air from the upper oven and directs it laterally away from the space between the ovens, while the second air guiding path extracts exhaust air from the lower oven and directs it downward. This extraction prevents exhaust air from contacting electrical wiring and components.
Solution Approach 2:
The air guiding paths act as intermediary channels that mediate between the oven cavities and the surrounding environment. These paths provide controlled routes for air flow that prevent direct interaction between exhaust air and sensitive components, while still allowing effective heat dissipation from both ovens.
3Device complexity
If a simple air flow arrangement is used, then device complexity is reduced, but adequate cooling of oven components and maintenance of cooking temperatures cannot be ensured
Solution Approach 1:
The air flow arrangement merges cooling air intake and exhaust air discharge functions into integrated paths. The first air guiding path combines cooling air intake at the upper oven with exhaust air discharge from the same oven, while the second air guiding path combines cooling air intake at the lower oven with exhaust air discharge. This merging provides reliable cooling without requiring separate complex systems for each function.

AI summary
A double oven combination is configured to be “built-in” an area of a household—in other words, permanently secured relative to the household area and integrated with other elements of the household area to provide a consistent decorative appearance. The double oven combination comprises an upper oven and a lower oven each of which may be a convection or non-convection oven that cooks and heats food and other substances via radiant and convective heating, and a control panel. The double oven combination has an integrated cooling air and exhaust air flow arrangement for efficiently guiding exhaust air away from the upper oven and the lower oven while at the same time effectively flowing cooling air relative to the double oven combination to promote desired cooling of the double oven combination.
