Oven Door Handle Venting for Humid Air Discharge and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oven designs face issues with air tightness and insulation due to leakage of humid air between the inner and outer panels of the door, which affects the discharge of humid air and visibility through the oven door.
Innovation Solution
An exhaust apparatus is integrated into the oven door handle, featuring a cylindrical protrusion, sealing extensions with lips, and a washer for secure attachment between the inner and outer panels, ensuring air tightness and directing humid air from the cooking chamber to the outside through the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the exhaust apparatus is disposed between the inner panel and outer panel of the oven door, then the humid air discharge function is improved, but the air tightness and insulation deteriorate due to leakage between panels
Solution Approach 1:
The exhaust apparatus is nested within the door structure between the inner and outer panels. The exhaust tube extends from the cooking chamber through the door panels, with the discharge opening positioned at the handle location. This nesting approach allows the exhaust function to be integrated into the existing door structure without compromising air tightness, as the exhaust path is contained within the door's internal space rather than creating external leakage paths.
Solution Approach 2:
The exhaust apparatus acts as an intermediary component that provides a controlled path for humid air discharge. By positioning the exhaust opening at the handle location and directing the exhaust flow away from the door panels, it mediates between the need for humid air removal and the requirement for air tightness, preventing condensation and leakage while maintaining insulation.
2Shape
If the exhaust apparatus opening is positioned at the handle, then the esthetic appearance is improved, but the air tightness at connection points deteriorates
Solution Approach 1:
The exhaust apparatus is designed with localized sealing features at the connection points between the inner and outer panels. The exhaust tube connections incorporate sealing mechanisms specifically at these critical junctions, allowing the handle area to maintain its esthetic appearance while ensuring air tightness at the connection points through localized sealing solutions.
3Illumination intensity
If humid air leaks between the front panel and inner panel, then the visibility through the door deteriorates, but the insulation performance also worsens
Solution Approach 1:
The exhaust apparatus extracts humid air from the cooking chamber and directs it through a controlled path to the external environment via the handle opening. By removing the humid air source before it can leak between the door panels, this extraction approach prevents condensation on the glass surfaces, maintaining visibility, while also preserving insulation performance by eliminating the moisture that would otherwise compromise thermal efficiency.

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 solution effectively discharges humid air from the cooking chamber while preventing leakage and condensation, enhancing air tightness and user visibility by ensuring all air is directed through the exhaust system.
Implementation Method 1
the vapor produced inside the oven leaks between the front panel and the inner panel of the door... directing the humid air entering from the cooking chamber into the opening towards the outer panel
