Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction heating devices face challenges in effectively cooling high-temperature electric components and light source units, with cold air not being concentrated adequately, leading to inefficient heat dissipation and cooling of these components.
Innovation Solution
The design incorporates an air guide system that directs air output from a fan to concentrate cooling on high-temperature components and light source units, using a single air blowing fan to cool both the drive circuit and display units, with an air guide structure that enhances airflow to prevent leakage and ensure efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If cold air is induced to pass through a lower portion of the heating unit and light source unit, then the cooling coverage is expanded, but the cooling concentration on high-temperature components is insufficient
Solution Approach 1:
The air guide is divided into multiple air guide holes arranged in different regions (first air guide holes in the first region, second air guide holes in the second region). Each region directs air to different components: the first region targets high-temperature components while the second region targets the light source unit. This segmentation allows simultaneous optimization of cooling concentration for different components without compromising overall cooling coverage.
2Reliability
If multiple cooling systems are used for drive circuit and display unit, then cooling effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
A single air blowing fan is designed to serve multiple cooling functions. The fan blows air that is then distributed through different air guide holes to cool both the drive circuit and the display unit. This multi-functional design eliminates the need for separate cooling systems for different components, reducing device complexity and manufacturing cost while maintaining effective cooling performance across all heat-generating components.

AI summary
An electric range is provided. The electric range may include a case; at least one heating unit configured to heat an object; at least one drive circuit configured to drive the heating unit; at least one display configured to display visual information; at least one air blowing fan configured to output air; and at least one air guide configured to guide air output from the air blowing fan to the drive circuit. The air output from the air blowing fan may be supplied to a first end of the air guide, and a height of an upper surface of the first end of the air guide may be greater than a height of an upper surface of the air blowing fan. A first portion of the air output from the air blowing fan may be discharged through a gap between the upper surface of the first end of the air guide and the upper surface of the air blowing fan, and supplied to the display.
