Cooking Range Air Circulation Layout for Self-Cleaning Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking ranges face issues such as reduced lifespan and safety hazards due to high heat generation during self-cleaning modes, and potential damage to kitchen furniture from erroneous operation of controllers and heat concentration, especially in built-in types where cooling efficiency is compromised.
Innovation Solution
Incorporation of an air circulation mechanism with an exhaust slot and suction slots positioned around the exhaust slot to circulate air, reducing heat concentration and overheating by sucking in air through suction slots and discharging it outside through the exhaust slot, thereby minimizing heat transmission to adjacent surfaces and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If self cleaning mode is used to remove odor and wastes from the cavity, then cleaning effectiveness is improved, but heat concentration causes reduced lifespan and safety hazards
Solution Approach 1:
The patent extracts heat from the cooking range by introducing an air circulation mechanism with suction slots and exhaust slots. The suction slots draw in hot air from around the cavity, and the exhaust slots discharge it to the outside, preventing heat concentration that would otherwise reduce lifespan and create safety hazards during self-cleaning mode
Solution Approach 2:
The patent introduces air as an intermediary substance to transfer heat away from the cooking range. The air circulation mechanism uses suction slots to draw in hot air, transports it through ducts, and exhausts it through exhaust slots, serving as a mediator to remove excess heat without directly cooling the cavity
2Ease of operation
If controller is built-in to provide user interface, then ease of operation is improved, but risk of damage from heat and erroneous operation increases
Solution Approach 1:
The patent extracts the controller from the high-heat zone by positioning it outside the cavity and away from the heating elements. The air circulation mechanism further protects the controller by directing cooled air toward the control section, removing the harmful heat factor while maintaining ease of operation
Solution Approach 2:
The patent uses air circulation as an intermediary to create a thermal barrier between the heating elements and the controller. Cooled air is directed toward the control section, serving as a protective mediator that reduces heat exposure to the controller while allowing it to remain accessible for operation
3Productivity
If heat is concentrated in the cavity for cooking, then cooking efficiency is improved, but heat transmission to surrounding surfaces causes overheating and potential damage
Solution Approach 1:
The patent extracts excess heat from the cooking range by using suction slots positioned around the cavity to draw in hot air, and exhaust slots to discharge it to the outside. This prevents heat transmission to surrounding surfaces and components while maintaining cooking efficiency within the cavity
Solution Approach 2:
The patent introduces air circulation as an intermediary mechanism to manage heat transfer. The suction slots draw in hot air, the ducts transport it away from heat-sensitive areas, and the exhaust slots discharge it, creating a controlled thermal environment that maintains cooking efficiency while preventing harmful heat transmission
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The air circulation system effectively reduces temperature by up to 24-26°C near the exhaust slot, preventing overheating and potential damage to surrounding components and furniture, enhancing safety and extending the cooking range's lifespan.
Implementation Method 1
an air circulation mechanism having an exhaust slot and at least one suction slot and configured to suck air into the cooking range through the at least one suction slot and to discharge the air to the outside through the exhaust slot
Implementation Method 2
a heating source configured to provide heat to the cavity when the cooking range is operated
