Oven Camera Cooling Duct Layout for Heat and Contaminant Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking apparatuses face challenges in effectively cooling cameras installed inside cooking chambers to prevent heat damage and ensuring efficient cooling of electronic components, while also preventing foreign substances from entering the cooling system.
Innovation Solution
The cooking apparatus incorporates a dual cooling system with a camera cooling duct and fan that draws outside air to cool the camera and a separate electronic compartment cooling fan, ensuring the camera is intensively cooled without interfering with the airflow for the entire electronic compartment, and a suction duct design that prevents foreign substances from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is disposed close to the cooking chamber to clearly image the inside, then the imaging quality is improved, but the camera temperature rises due to heat exposure
Solution Approach 1:
The patent divides the cooling function into two separate systems: a camera cooling system with dedicated duct and fan for intensive cooling of the camera, and an electronic compartment cooling system for general cooling. This segmentation allows the camera to be cooled independently and intensively without interfering with the overall electronic compartment cooling, resolving the contradiction between close positioning for imaging quality and heat exposure.
2Productivity
If a suction duct is used to cool the camera, then the cooling efficiency is improved, but foreign substances such as water and oil may enter the duct
Solution Approach 1:
The patent introduces a filter as an intermediary component in the suction duct that allows air to pass through for cooling while blocking foreign substances such as water and oil. This mediator enables the suction duct to maintain high cooling efficiency while preventing harmful substances from entering the camera cooling system.
3Device complexity
If a single cooling system is used for both camera and electronic compartment, then the device complexity is reduced, but the cooling efficiency for each component decreases
Solution Approach 1:
The patent implements separate cooling ducts and fans for the camera and the electronic compartment. The camera cooling duct is specifically designed to draw air from outside the cooking apparatus and discharge it to the camera, while the electronic compartment has its own cooling system. This segmentation ensures that each component receives dedicated cooling airflow, maintaining high cooling efficiency for both the camera and electronic components without excessive complexity.
4Device complexity
If the camera cooling airflow is integrated with the electronic compartment cooling airflow, then the device complexity is reduced, but the camera cooling efficiency is compromised
Solution Approach 1:
The patent extracts the camera cooling airflow path from the electronic compartment cooling system. The camera cooling duct is configured to draw air directly from outside the cooking apparatus, separate from the electronic compartment air intake. This extraction ensures that the camera receives dedicated cooling airflow that is not compromised by the electronic compartment cooling requirements, maintaining high camera cooling efficiency while keeping the overall system manageable.
