Double Oven Airflow Layout for Built-In Cooling and Exhaust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Built-in double oven installations require an effective cooling air and exhaust air flow arrangement to maintain selected cooking temperatures and prevent heat-related issues, such as electrical component damage, while ensuring efficient heat dissipation and cooling of the oven components.
Innovation Solution
An integrated cooling air and exhaust air flow arrangement featuring separate guiding paths for cooling and exhaust air, with a cooling air only path directing air downward to a base channel below the lower oven, and a mid-channel above the lower oven to mix with heated air from the upper oven, utilizing a latch plate shield to guide heated air and introduce cooling air effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate cooling and exhaust air paths are used, then cooling effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines separate cooling air paths and exhaust air paths into a unified base channel system. Cooling air from above the upper oven and exhaust air from both ovens converge at the base channel below the lower oven, creating an integrated flow arrangement that maintains effective cooling while reducing structural complexity compared to completely separate systems
Solution Approach 2:
The air flow system is segmented into distinct guiding paths: a first path for cooling air above the upper oven, a second path for exhaust air from the upper oven, a third path for cooling air at the lower oven, and a fourth path for exhaust air from the lower oven. These segmented paths converge at the base channel, allowing independent control of cooling and exhaust functions while maintaining system integration
2Area of stationary object
If built-in double oven installation is implemented, then space efficiency is improved, but heat dissipation effectiveness deteriorates
Solution Approach 1:
The patent utilizes the vertical dimension by directing air flows both downward to the base channel and laterally through side channels. This multi-directional approach in three-dimensional space allows effective heat dissipation and cooling within the constrained built-in installation footprint, transforming the limited two-dimensional installation area into an effective three-dimensional air flow management system

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.
