Rear Burner Assembly Layout for Cleaner Cooking Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances face challenges in cleaning and food contamination due to the placement of burners at the bottom of the cooking chamber, which leads to difficulty in removing food leftovers and potential seepage into the floor area.
Innovation Solution
A cooking appliance design featuring a burner assembly positioned at the rear wall of the cooking chamber, with a partition plate separating the cooking area into two chambers, allowing for efficient air circulation and preventing food contamination while enabling easier cleaning by eliminating the need for coupling holes in the recessed area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the burner is positioned at the bottom of the cooking chamber, then the cooking appliance can maintain a compact structure, but cleaning becomes difficult and food leftovers may seep into the floor area
Solution Approach 1:
The cooking chamber is divided into two separate chambers by a partition plate: a first chamber for cooking and a second chamber for housing the burner and fan. This segmentation allows the burner to be positioned away from the bottom floor area while maintaining compact overall structure, and enables independent cleaning of each chamber without interference from the other components.
2Volume of moving object
If the burner is positioned at the bottom of the cooking chamber, then space utilization is efficient, but food contamination risk increases due to difficulty in removing food leftovers
Solution Approach 1:
The burner and fan assembly is extracted from the traditional bottom position and relocated to the rear wall area, creating a separate second chamber. This extraction removes the potential contamination source away from the cooking area and floor region, eliminating the risk of food leftovers seeping into the floor while preserving efficient space utilization through the partitioned design.
3Ease of operation
If a partition plate is introduced to separate the cooking chamber, then cleaning efficiency improves and food contamination is prevented, but device complexity increases
Solution Approach 1:
The partition plate serves multiple functions simultaneously: it separates the cooking chamber into two independent chambers for improved cleaning access, positions the burner and fan assembly away from the floor area to prevent contamination, and maintains compact overall structure. This multi-functionality justifies the added structural element by delivering multiple benefits from a single design feature.
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 design enhances cleaning efficiency and prevents food contamination by directing heated air evenly throughout the cooking chamber, improving cooking performance and reducing the risk of food residue reaching the floor.
Implementation Method 1
a burner provided in the second chamber to burn a gas, thereby generating flame
Implementation Method 2
a fan provided in the second chamber to allow heated air to flow

AI summary
A cooking appliance includes a cavity to define a cooking chamber, a door to open and close the cooking chamber, a partition plate to partition the cavity into a first chamber and a second chamber, the partition plate facing the door in the closed state, wherein the door closes the first chamber, a burner provided in the second chamber to burn gas, thereby generating flame, and a fan provided in the second chamber to allow heated air to flow.
