Cooking Appliance Heater Installation Structure for Easier Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances face challenges in efficient heater installation and maintenance, particularly in built-in types, which complicates heater replacement and after-sales service, leading to increased service costs and reduced heater 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 easier replacement and maintenance, and includes an insulating heater cover and perforated installation holes for efficient airflow and heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the heater is integrated into the cooking compartment structure, then the appliance achieves compact design and efficient heat distribution, but heater replacement and maintenance become difficult and costly
Solution Approach 1:
The heater assembly is segmented into separate components: the heater element itself and the heater installation member (bracket/support structure). This segmentation allows the heater to be detached and replaced independently from the main appliance body, facilitating easy maintenance while maintaining compact integration during normal operation
Solution Approach 2:
The heater installation member incorporates detachable connections that transition between fixed and movable states. During operation, the heater is securely fixed for efficient heat distribution; during maintenance, the connections can be detached to enable easy removal and replacement of the heater element
2Device complexity
If the cooling flow path is integrated with the heater structure, then the appliance achieves compact design, but heater efficiency decreases due to heat loss
Solution Approach 1:
The cooling flow path is extracted and separated from the heater structure into distinct spatial zones. The heater installation member acts as a separator, positioning the heater away from the cooling airflow path. This extraction prevents heat loss to the cooling system while maintaining compact overall appliance design through optimized space arrangement
