Mobile Kitchen Venting Layout for Heat and Smoke Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile kitchens face challenges with heat buildup, noise, and smoke production due to trapped heat and uncontrolled combustion from open flame burners, particularly in confined spaces and hot climates, leading to uncomfortable working conditions and potential health hazards.
Innovation Solution
The design incorporates air channels around appliances to isolate excess heat and noise, using blowers to vent heat and smoke outside, and features double-walled exhaust channels and strategically positioned blowers to maintain a cooler workspace while ensuring efficient combustion with distillate fuel burners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cooking appliances with open flame burners are used in a mobile kitchen, then cooking functionality is provided, but heat and noise are trapped within the confined space raising temperature to over 49°C
Solution Approach 1:
The patent extracts the harmful heat and noise from the workspace by routing exhaust gases through channels in the trailer walls away from the kitchen area. The combustion products are diverted outside the confined space, removing the thermal burden from the workspace while preserving the cooking function.
Solution Approach 2:
The patent introduces air channels and blowers as intermediary elements between the combustion sources and the workspace. These channels act as conduits to transport hot exhaust gases away from the kitchen area, while the blowers provide forced ventilation to maintain acceptable temperature levels in the workspace.
2Ease of operation
If open flame burners are used for cooking, then cooking is enabled, but smoke, noxious gases, and carbon build-up are produced and trapped within the trailer
Solution Approach 1:
The patent extracts harmful combustion products (smoke, noxious gases, carbon) from the workspace by channeling them through exhaust pathways in the trailer walls. This removal prevents accumulation of harmful substances within the confined kitchen space while maintaining open flame cooking capability.
Solution Approach 2:
The patent implements continuous ventilation through blowers that operate to maintain constant air exchange in the workspace. This continuous action ensures that harmful gases are continuously removed and fresh air is supplied, preventing carbon build-up and maintaining air quality during cooking operations.
3Adaptability or versatility
If all appliances are arranged within a trailer for mobility, then the kitchen is mobile, but space is confined causing heat to remain trapped
Solution Approach 1:
The patent extracts heat from the confined trailer space by creating dedicated exhaust channels that route hot gases outside the trailer. This allows the kitchen to remain mobile and confined while preventing heat accumulation through external venting pathways.
Solution Approach 2:
The patent addresses the three-dimensional heat trapping problem by creating vertical and lateral exhaust pathways through the trailer structure. The air channels extend in multiple dimensions (through walls, roof, or sides) to provide efficient heat removal from the confined internal space.
4Ease of operation
If open flame burners are used, then cooking is possible, but uncontrolled excess noise is produced within the confined space
Solution Approach 1:
The patent extracts noise from the workspace by routing exhaust gases through channels that lead away from the kitchen area. The combustion noise and burner sounds are channeled outside the trailer or to areas away from the workspace, reducing noise exposure for users while preserving cooking functionality.
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
This configuration effectively reduces heat and noise within the mobile kitchen, maintaining a cooler workspace and minimizing smoke and carbon buildup, enhancing operational comfort and safety.
Implementation Method 1
One or more air channels are disposed about each of the appliances, with each air channel being adapted to substantially isolate excess heat from combustion of the distillate fuel from the workspace within the kitchen
Implementation Method 2
One or more first air blowers are associated with the air channels, and these air blowers are adapted to force air through the air channels so that the excess heat is vented to an exterior of the housing
Implementation Method 3
One or more second air blowers are coupled to the housing, with each of these second air blower being adapted to replace a predetermined volume of air from within the workspace at least once per minute
Implementation Method 4
Each appliance is heated by combustion of a distillate fuel

AI summary
A mobile kitchen comprises a housing disposed atop one or more wheel axles and a plurality of appliances disposed within the housing. Each appliance is heated by combustion of a distillate fuel. One or more air channels are disposed about each of the appliances, such that each air channel substantially isolates excess heat from combustion of the distillate fuel from a workspace within the housing. One or more first air blowers are associated with the air channels, and each is adapted to force air through the air channels and vent the excess heat to the exterior of the housing. One or more second air blowers are coupled to the housing, and each second air blower is adapted to vent a predetermined volume of air from within the workspace at least once per minute.
