Dual-Compartment Oven Airflow Structure for Temperature Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens with multiple cooking compartments face challenges in maintaining a significant temperature difference between compartments due to heat transfer and incomplete sealing, limiting the ability to perform different cooking processes simultaneously.
Innovation Solution
The oven design incorporates a casing with separate cooking compartments, a divider, first and second circulating fans, an inlet unit for introducing outside air, and an outlet unit for discharging heated air, allowing for independent temperature control of each compartment through the use of inlet and outlet valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a divider is positioned between the first cooking compartment and the second compartment to separate them, then the cooking compartments are divided and can be positioned separately, but complete sealing is difficult and heat transfer occurs between compartments
Solution Approach 1:
The oven is divided into multiple cooking compartments (first cooking compartment and second compartment) separated by a divider, allowing independent temperature control and different cooking processes to occur simultaneously in each compartment
Solution Approach 2:
An inlet unit is introduced as an intermediary component to supply outside air to the cooking compartments. This mediator helps maintain temperature differences between compartments by providing fresh air that compensates for heat transfer losses and enables independent temperature management
2Loss of energy
If the first cooking compartment and the second compartment are sealed completely, then heat transfer between compartments is prevented, but it becomes limited to conduct only cooking processes requiring similar temperatures
Solution Approach 1:
The inlet unit provides dynamic air supply to the cooking compartments, allowing the system to adapt temperature conditions in real-time. This enables the oven to switch between different cooking modes and maintain different temperatures in each compartment, greatly enhancing cooking versatility
Solution Approach 2:
By introducing outside air through the inlet unit, the temperature parameter in each cooking compartment can be independently adjusted and maintained at different levels. This parameter control allows simultaneous conductance of different cooking processes requiring different temperature conditions
3Adaptability or versatility
If outside air is introduced to maintain temperature difference between compartments, then different cooking processes can be conducted simultaneously, but device complexity increases with inlet unit components
Solution Approach 1:
The inlet unit is designed to serve multiple functions: it supplies outside air to maintain temperature differences, enables different cooking processes in each compartment, and can be controlled to adapt to various cooking requirements. This multi-functionality justifies the added complexity by providing significant versatility benefits
