Partitioned Cooking Chamber Layout for Uniform Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances face challenges in achieving uniform heating and efficient air circulation, leading to hotspots and difficulties in cleaning, as well as potential food contamination and leakage of food leftovers due to the placement of burners at the bottom of the cooking chamber.
Innovation Solution
A cooking appliance design featuring a partition plate that separates the cooking chamber into two compartments, with a burner assembly located at the rear wall, allowing for improved air circulation and heated air distribution, and a fan system that ensures even heating and prevents food contamination by keeping the burner area isolated from food residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the burner is placed at the bottom of the cooking chamber, then the structure is simplified, but food contamination and leakage of food leftovers occur
Solution Approach 1:
The cooking chamber is divided into two separate chambers by a partition plate. The first chamber accommodates food and the second chamber houses the burner and fan. This segmentation prevents food contamination while maintaining structural simplicity.
Solution Approach 2:
The partition plate acts as an intermediary barrier between the food chamber and the burner chamber. It prevents direct contact between food and potential contaminants from the burner area, while still allowing the system to function as an integrated cooking appliance.
2Ease of manufacture
If the burner is placed at the bottom of the cooking chamber, then installation is easier, but cleaning becomes difficult due to coupling holes
Solution Approach 1:
By segmenting the cooking chamber into two separate chambers with the partition plate, the design eliminates the need for coupling holes at the bottom. The partition plate provides a clean separation that simplifies both installation and cleaning operations.
3Device complexity
If conventional air circulation is used, then the system is simple, but heating uniformity is poor with hotspots forming
Solution Approach 1:
The fan in the second chamber pre-heats air before it enters the food chamber through the partition plate. This preliminary heating action ensures uniform heat distribution throughout the cooking chamber, eliminating hotspots while maintaining system simplicity.
Solution Approach 2:
The partition plate with its openings acts as an intermediary that controls air flow between chambers. It allows pre-heated air to pass from the second chamber to the first chamber, ensuring uniform heating while maintaining the simplicity of the air circulation system.
