Electric Range Air Blower Support Design for Cooling Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric ranges face cooling efficiency issues due to insufficient air intake by the air blower fan, leading to overheating and potential operational failures.
Innovation Solution
The design includes a second support structure that separates the air blower fan from the case, creating a larger intake area and using ribs to isolate the intake space from hot internal components, ensuring cooler external air is drawn in and directing airflow efficiently to cool electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air blower fan is positioned close to the case to save space, then device complexity is reduced, but cooling efficiency deteriorates due to insufficient air intake
Solution Approach 1:
The patent introduces a vertically extended air intake passage that protrudes from the case surface, utilizing the vertical dimension to increase air intake area without expanding the horizontal footprint. This allows the fan to be positioned close to the case while still accessing sufficient ambient air for effective cooling.
Solution Approach 2:
The air intake system is segmented into multiple components: the case body, the protruding air intake passage, and the fan assembly. This segmentation allows the air intake passage to be optimized independently for maximum air flow while keeping the fan compact and close to the case, resolving the conflict between space utilization and cooling efficiency.
2Reliability
If the fan intake area is increased to improve cooling efficiency, then cooling efficiency is improved, but device complexity increases due to additional structural components
Solution Approach 1:
The protruding air intake passage serves multiple functions: it increases the air intake area for the fan, provides structural support for the fan assembly, and acts as a guide for air flow. By combining multiple functions into a single component, the patent achieves improved cooling efficiency without proportionally increasing device complexity.
Solution Approach 2:
The air intake passage is merged with the case structure rather than being a separate attachment, and the fan mounting structure is integrated into the passage design. This merging reduces the number of discrete components and simplifies assembly while maintaining the enlarged air intake area necessary for effective cooling.

AI summary
An electric range is provided that may include a case, and a support mounted on the case. The support may include a first region in which an air blower fan may be disposed, and a second region in which a printed circuit board may be disposed. A lower surface of the first region may be separated from the case.
