Solution Overview
Problem
Existing oven range designs face challenges in efficiently cooling the electronic component unit, particularly the printed circuit board (PCB), due to the high unit cost and inefficiency of the frontward-rearward cooling flow path, which requires additional configurations like insulation plates and fans, leading to manufacturing cost inefficiencies.
Innovation Solution
A cooling flow path is formed in a widthwise direction within the controller, utilizing a fan assembly and guide to direct airflow efficiently to the control PCB, reducing heat transfer and manufacturing costs by simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a frontward-rearward cooling flow path is used to cool the electronic component unit, then cooling function is provided, but unit cost increases due to additional insulation plates and fans
Solution Approach 1:
The patent extracts and eliminates unnecessary components (insulation plates and fans) from the cooling system by utilizing the natural convection current formed by the oven's heating operation. The heating element naturally heats air that rises and circulates through the electronic component unit, providing cooling without requiring additional active cooling devices.
Solution Approach 2:
The oven's own heating operation creates a natural convection current that serves the dual purpose of heating food and cooling electronic components. The system uses its inherent thermal dynamics to cool itself, eliminating the need for separate cooling mechanisms and reducing manufacturing costs.
2Temperature
If a frontward-rearward cooling flow path is implemented, then cooling function is achieved, but device complexity increases due to additional configurations
Solution Approach 1:
The patent removes complex cooling flow path configurations, insulation plates, and additional fans from the system. By relying on natural convection, the design simplifies the overall structure while maintaining effective cooling functionality.
Solution Approach 2:
The natural convection current serves multiple functions simultaneously: it circulates hot air for heating food in the oven cavity while also passing through the electronic component unit to provide cooling. This multi-functionality eliminates the need for separate cooling systems and reduces device complexity.
3Ease of manufacture
If conventional cooling methods are used, then cooling is provided, but electronic component unit cooling efficiency is insufficient
Solution Approach 1:
The patent positions the electronic component unit within the natural convection current path, utilizing the vertical temperature gradient created by heating elements. Hot air rises vertically and passes through the electronic components, creating an effective cooling flow path without requiring complex mechanical systems.
Solution Approach 2:
The oven's heating operation automatically generates the cooling effect for electronic components through natural convection. The system self-regulates the cooling process based on its operational state, providing efficient cooling without additional control mechanisms or complex manufacturing requirements.
