Smoke Exhaust Hood With Overhead Heating for Dual-Direction Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smoke exhaust hood apparatuses for cooking often lead to uneven cooking due to heat being applied only from below, making it difficult to monitor the cooking progress of food, especially the lower surface, which can result in overcooking or burning.
Innovation Solution
A smoke exhaust hood apparatus with a turnable heater assembly mounted outside the exhaust hood, allowing heat to be applied from above the food, and featuring a multi-layered plate structure with a heating element that can move upwards and downwards to adjust heat intensity and prevent eddy currents, while also providing height adjustment for optimal space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heat is applied only from below using a conventional heat source, then the cooking process is simple, but the cooking uniformity deteriorates and the lower surface of food cannot be monitored
Solution Approach 1:
The heating system is segmented into two independent heating sources: a lower heat source (conventional hot plate or grill) and an upper heat source (heater assembly mounted on the exhaust hood). This segmentation allows each heat source to independently heat different surfaces of the food, achieving uniform cooking from both top and bottom simultaneously
Solution Approach 2:
The heating approach transitions from one-dimensional (bottom-only heating) to three-dimensional heating by adding an upper heat source. The heater assembly is positioned above the food and directed downward, creating bidirectional heat application that encompasses the food from multiple spatial dimensions, improving cooking uniformity
2Manufacturing precision
If a heater assembly is added to provide heat from above, then cooking uniformity improves, but the device complexity increases
Solution Approach 1:
The heater assembly is merged with the exhaust hood structure, utilizing the existing hood framework as the mounting base. The heater is integrated into the hood's body rather than being a separate standalone unit, and the control system combines both heating and exhaust functions into a unified apparatus, reducing overall system complexity
Solution Approach 2:
The exhaust hood structure serves multiple functions: it continues to provide smoke extraction while simultaneously serving as the mounting structure for the heater assembly. The upper surface of the hood acts as both the exhaust outlet and the heat application surface, eliminating the need for separate structural components
3Device complexity
If the heater assembly is fixed in position, then the structure is simple, but the adaptability to different cooking needs deteriorates
Solution Approach 1:
The heater assembly is designed with movable and adjustable components, including the ability to change the heater's position relative to the food and adjust the heating intensity. The control system allows dynamic adjustment of heat output to match different cooking requirements, food types, and cooking stages
