Gas cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas cookers lack effective cooling for internal electronic components and generate high-temperature exhaust gas, leading to potential malfunctions and user discomfort.
Innovation Solution
A gas cooker design featuring a main fan and sub-fan system that cools internal components and partitions the internal space to separate the burner unit from the regulator and valve unit, allowing external air to cool these components while discharging cooled air with burned gas, reducing exhaust temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electronic components are provided inside the case without a separate cooling structure, then the device complexity is reduced, but the reliability deteriorates due to potential malfunctions from overheating
Solution Approach 1:
The fan originally designed for exhaust gas discharge is made to serve dual functions: exhaust gas discharge and internal case cooling. By positioning the fan to simultaneously draw air through the case for cooling electronic components and discharge burned gas, the patent eliminates the need for a separate cooling structure while maintaining component reliability
Solution Approach 2:
The exhaust function and cooling function are merged into a single air flow path and fan system. The fan draws air through the case, cooling electronic components along the way, and then discharges this cooled air along with burned gas through the exhaust portion, combining multiple functions into one system
2Volume of stationary object
If the burner unit is positioned close to the operation unit, then the volume of the case is reduced, but the reliability deteriorates due to high temperature affecting electronic components
Solution Approach 1:
The fan continuously draws cooling air through the case, creating a continuous cooling flow that passes over electronic components including the operation unit. This continuous cooling action maintains reliable operation of electronic components even when positioned close to the burner unit, allowing compact case design
3Device complexity
If the exhaust gas is discharged directly without cooling, then the device complexity is reduced, but the object-affected harmful factors increase due to high temperature exhaust gas causing user discomfort
Solution Approach 1:
The high-temperature exhaust gas, initially a harmful factor, is used to drive natural convection currents that enhance the cooling effect. The temperature difference between hot exhaust gas and cooler ambient air creates convection currents that improve air circulation through the case, intensifying the cooling of electronic components while the fan ensures proper discharge
