Drawer Oven Air Outlet Layout for Lower Height and Hidden Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Built-in cooking devices face challenges in air outlet structure design, where the existing air outlet ducts are too tall, increasing the height of the cooking device and compromising its aesthetic appeal and interior design compatibility, while also requiring complex duct structures that raise operational costs and risk of short circuits.
Innovation Solution
The air outlet structure is redesigned to utilize the side wall of the heating chamber and the lower side portion of the front wall, eliminating the need for a separate air outlet duct below the heating chamber, allowing air to flow along the side wall and exit through openings on the side, thus reducing the overall height and simplifying the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate air outlet duct below the heating chamber is used, then air can be discharged effectively, but the height of the cooking device increases and the design becomes complex
Solution Approach 1:
The patent merges the air outlet duct function with the side wall structure of the heating chamber. The air outlet duct is formed by utilizing the side wall space, eliminating the need for a separate below-chamber duct structure. This integration reduces the overall device height while maintaining effective air discharge functionality.
Solution Approach 2:
Instead of discharging air vertically downward through a below-chamber duct (vertical dimension), the patent redirects air discharge through the side wall (horizontal dimension). This dimensional change allows air to exit through openings on the side, reducing the height requirement while maintaining discharge effectiveness.
2Reliability
If a separate air outlet duct below the heating chamber is used, then air can be discharged effectively, but the duct structure becomes complex and manufacturing costs increase
Solution Approach 1:
The air outlet duct function is merged with the existing side wall structure of the heating chamber. By forming the air outlet duct using the side wall space rather than adding a separate below-chamber duct, the patent simplifies the overall duct structure and reduces manufacturing complexity while maintaining air discharge effectiveness.
Solution Approach 2:
The side wall of the heating chamber serves multiple functions: it provides structural support, defines the chamber boundary, and simultaneously forms the air outlet duct. This multi-functionality eliminates the need for dedicated separate duct components, reducing structural complexity and manufacturing costs.
3Productivity
If air outlet openings are positioned at the lower front side, then air discharge is efficient, but the openings are visible and compromise aesthetic appearance
Solution Approach 1:
The patent relocates air outlet openings from the lower front side (vertical dimension) to the side wall (horizontal dimension). This positional change in another dimension allows air to be discharged efficiently while the openings are less visually prominent, improving aesthetic appearance without sacrificing discharge efficiency.
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
This solution reduces the necessary height for air inlet and outlet structures, enhances the device's exterior appearance, decreases manufacturing costs, and prevents short circuits by guiding air downward, allowing for a more efficient use of space and improved user safety.
Implementation Method 1
When a cooling fan 56 within the electric component chamber disposed at a rear portion of the cooking device body 51 is activated, cooling air F1 is taken in via the front side air inlet port 63 through the air inlet portion 60, reaches a depth portion chamber at a rear side of a depth wall of the heating chamber 53 of the cooking device body 1, and is further blown into the interior of the cooking device body 51 by the cooling fan 56
Implementation Method 2
an air outlet portion for discharging an inside air having been sent into the heating chamber and containing heat and vapor generated during cooking of the object to be cooked

AI summary
The invention provides a drawer type built-in cooking device, wherein an air outlet portion 10 for discharging the inside air containing heat and vapor generated during cooking of an object to be cooked has an air outlet duct 11 communicated from an air outlet port area 3b formed on a side wall of the heating chamber 3 to a lower side portion of a front wall 1a of the cooking device body 1. The outlet air flow flowing through the air outlet duct 11 is sent downward from an air outlet opening 13 formed to a lower side portion of the front wall 1a of the cooking device body 1 and discharged to the exterior of the device. The present invention enables to eliminate the prior art air inlet and outlet duct structure disposed below the heating chamber 3, and therefore, the height of the heating chamber can be increased correspondingly. Further, the air outlet opening 13 is hidden from the exterior without having to attach a louver since the opening is covered by a door 2a when the door is closed, so that the exterior design thereof is improved.
