Oven Lamp Double Insulation Structure to Reduce Overheating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oven lamps are prone to overheating due to the high temperatures within the cooking chamber, which reduces their lifespan.
Innovation Solution
A double insulation structure is implemented in the oven, comprising a first insulating case that primarily shields the lamp from heat and a second insulating case that secondarily shields it, minimizing heat exposure and preventing overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single insulation structure is used for the lamp, then the structure is simple and easy to manufacture, but the lamp is still prone to overheating and reduced lifespan
Solution Approach 1:
The patent implements a nested insulation structure where an inner insulating case is placed inside an outer insulating case, creating multiple layers of thermal protection around the lamp. This nested configuration provides enhanced heat isolation without requiring a completely different structural approach, thereby improving lamp lifespan while maintaining reasonable structural simplicity.
Solution Approach 2:
The insulation system is divided into separate modular components: an inner insulating case and an outer insulating case, each serving distinct thermal protection functions. This segmentation allows for optimized heat barrier performance at each layer while enabling easier manufacturing and assembly compared to a monolithic insulation structure.
2Object-affected harmful factors
If the lamp is disposed directly in the cooking chamber, then the structure is simple, but the lamp is exposed to high heat and overheats
Solution Approach 1:
The patent introduces insulating cases as intermediary structures between the high-temperature cooking chamber environment and the lamp. These intermediary cases create thermal buffer zones that filter and reduce the harmful heat exposure reaching the lamp, thereby protecting it from overheating while maintaining its functional position near the cooking chamber.
Solution Approach 2:
The lamp is nested within multiple insulating cases that are positioned between the lamp and the cooking chamber heat source. This nested arrangement creates progressive thermal barriers that effectively reduce heat exposure to the lamp without requiring complete isolation from the cooking chamber.

Function Achieved in This Case
The double insulation structure effectively reduces the lamp's temperature, thereby increasing its lifespan and ensuring optimal operation.
Implementation Method 1
a first insulating case mounted on one surface of the cooking chamber, a first case coupled to the first insulating case to form a first insulated space, a second insulating case having at least a part thereof disposed inside the first insulated space, a second case coupled to the second insulating case to form a second insulated space, and a lamp disposed inside the second insulated space to be doubly insulated from heat of the cooking chamber
