Cooking Appliance Door Cooling Flow Path to Block Heat and Oil Mist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a cooking appliance is positioned above a heating cooking device, heat and oil mist generated from the heating cooking device can adversely affect the operation of the cooking appliance, particularly damaging components like the display unit and interfering with the formation of an air curtain due to air leaks.
Innovation Solution
The cooking appliance is designed with a structure that includes a display module, a cooling flow path unit, and a shielding unit, where the cooling flow path unit is positioned behind the display module to effectively cool electronic components and form an air curtain, while the shielding unit blocks electromagnetic waves, and air is discharged through outlets to prevent heat and oil mist ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cooking appliance is disposed above the heating cooking device to save space and improve convenience, then the installation efficiency and user convenience are improved, but the heat and oil mist from the heating device can penetrate into the cooking appliance and damage the display unit and electronic components
Solution Approach 1:
An air guide is introduced as an intermediary component between the heating cooking device and the cooking appliance. The air guide creates a separated flow path that allows heat and oil mist to pass through below the cooking appliance while preventing them from penetrating into the display unit and electronic components mounted on the cooking appliance, thus protecting sensitive components while maintaining the space-saving configuration
Solution Approach 2:
The space above the heating cooking device is segmented into different functional zones using the air guide. The air guide divides the airflow into a lower path for heat and oil mist discharge and an upper protected zone for the cooking appliance components, allowing simultaneous achievement of space efficiency and component protection
2Temperature
If air is allowed to flow freely through the door for cooling components, then the cooling efficiency is improved, but air leakage through the air guide gap interferes with air curtain formation and reduces cooling effectiveness
Solution Approach 1:
The air guide structure is designed with differentiated local qualities: the main body allows free air flow for cooling components, while the edge portion incorporates a specific structure that prevents air leakage. This localized control of air flow properties enables simultaneous achievement of cooling efficiency and air curtain integrity
Solution Approach 2:
The air guide edge structure creates a simplified version of the air curtain barrier at the critical leakage point, copying the protective function of the main air curtain at the specific location where leakage would occur, thus maintaining overall system reliability
