Cooking Cavity Rear Layout for Larger Oven Space and Component Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking apparatuses have limited cooking cavity height and width due to the placement of components, and there is a need for efficient use of rear space to accommodate heating elements and cooling systems effectively.
Innovation Solution
The cooking apparatus utilizes a rack or plate instead of a turntable, allowing for increased height and width by placing components like a magnetron, high voltage transformer, and convection heater assembly at the rear, with a cooling fan positioned to create an effective cooling flow path, enhancing the use of rear space for expanded cavity dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If components are placed at one side or upper side of the cooking cavity, then the cooking cavity height is maintained, but the cooking cavity width and rear space utilization are limited
Solution Approach 1:
The patent relocates components from traditional side/upper positions to the rear space of the cooking cavity, utilizing the depth dimension that was previously underutilized. This dimensional shift allows the cooking cavity width and height to be maximized while components are accommodated in the rear depth space, effectively resolving the spatial conflict between component placement and cooking cavity dimensions.
2Area of stationary object
If components are installed at the rear space, then the cooking cavity width and height are expanded, but the cooling of components becomes more difficult
Solution Approach 1:
The patent introduces a cooling fan as an intermediary device positioned in the rear space to actively manage heat dissipation. The cooling fan creates a forced convection current that draws air through the cooking cavity and across the components in the rear space, providing effective cooling without requiring additional space beyond the rear compartment. This mediator enables both expanded cooking cavity dimensions and adequate component cooling.
3Productivity
If a turntable is used in the cooking cavity, then the cooking process is enhanced, but the cooking cavity height and width are restricted
Solution Approach 1:
The patent extracts the turntable mechanism from the cooking cavity and relocates it to the rear space among the other components. This extraction removes the spatial constraint that the turntable imposed on the cooking cavity dimensions, allowing the cavity width and height to be maximized. The turntable function is preserved in the rear space, maintaining cooking efficiency while eliminating the dimensional restriction.
