Detachable Heater Mounting Structure for Easier Oven Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances face challenges in facilitating easy replacement and after-sales service of heaters, leading to increased service costs and reduced efficiency due to the integration of heating and cooling flow paths.
Innovation Solution
A cooking appliance with an improved heater installation structure, featuring a detachable heater installation member that isolates the cooling flow path from the heater, allowing for separate maintenance and replacement, and includes an insulating heater cover for efficient heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the heater is integrated with the cooling flow path in a fixed structure, then the appliance structure is simplified, but the heater replacement and maintenance becomes difficult
Solution Approach 1:
The heater assembly is segmented from the main appliance body through a detachable heater installation member. The heater can be independently removed from the cooling flow path structure, allowing maintenance without disassembling the entire appliance while maintaining structural simplicity during normal operation.
Solution Approach 2:
The heater installation member transitions from a fixed integrated state during operation to a detachable state during maintenance. The dynamic capability of detaching and reattaching the heater allows the system to switch between operational simplicity and maintenance accessibility.
2Reliability
If the heater is permanently installed in the appliance, then service costs are reduced through fewer disassemblies, but replacement capability is lost
Solution Approach 1:
The heater installation member is designed as a separate modular component that can be detached and replaced. This segmentation maintains stable installation during operation while enabling replacement when needed, balancing reliability with adaptability.
Solution Approach 2:
The heater can be discarded (removed) from the appliance for replacement or maintenance, and the installation member is designed to recover and securely hold a new heater. This allows periodic replacement while maintaining stable installation during each operational cycle.
3Volume of stationary object
If the cooling flow path and heater are integrated, then the appliance structure is compact, but heater efficiency is reduced due to heat loss
Solution Approach 1:
The heater installation member is segmented as a separate module that can be positioned to optimize heat management. This allows compact overall structure while enabling thermal isolation measures to reduce heat loss from the heater to the cooling flow path.
Solution Approach 2:
The heater installation member acts as an intermediary between the heater and the cooling flow path structure. This intermediate component can incorporate thermal insulation or heat management features that reduce energy loss while maintaining the compact integrated appearance of the appliance.
