Ceramic Heater Supporter for High-Power Electric Hob Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric hobs with sheath heaters have low output power, making rapid cooking difficult, and installing high-power tube heaters is challenging due to heat transfer issues that can damage the heater base and reflector.
Innovation Solution
A heater supporter system that includes a heat-resistant material for fixing the tube heater and an elastic supporting part to minimize heat damage, allowing for easy installation and efficient heat transfer, comprising a first supporter fixed to the tube heater, a second supporter fixed to the heater base or reflector, and a heater holder with predetermined elasticity to absorb external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a tube heater is installed at the heater base and/or reflector, then high-power heating is achieved, but heat is transferred to the heater base and/or reflector causing damage
Solution Approach 1:
The patent introduces a heater supporter as an intermediary component between the tube heater and the heater base/reflector. This supporter includes a heat-resistant material portion that contacts the tube heater and an elastic supporting portion that contacts the heater base or reflector, acting as a mediator to prevent direct heat transfer to the heater base and reflector while still providing mechanical support.
Solution Approach 2:
The heater supporter is constructed from composite materials with different properties: a heat-resistant material portion (such as ceramic or heat-resistant polymer) that can withstand high temperatures from the tube heater, and an elastic supporting portion (such as rubber or elastic polymer) that provides mechanical support and elasticity. This composite structure allows the supporter to simultaneously handle thermal and mechanical requirements.
2Ease of manufacture
If a sheath heater is used as heating source, then installation is simple, but output power is relatively low making rapid cooking difficult
Solution Approach 1:
The patent changes the key parameter of the heating element from a sheath heater configuration to a tube heater configuration with a filament inside. This parameter change enables significantly higher output power while the heater supporter system maintains ease of installation through modular design and clear mounting procedures.
3Ease of manufacture
If additional members are used to install tube heater, then tube heater can be installed, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into the heater supporter component: it provides mechanical support for the tube heater, acts as a thermal insulator, and serves as a mounting interface with the heater base or reflector. By combining these functions into a single integrated component rather than using separate additional members, the system achieves installation feasibility without significantly increasing device complexity.

AI summary
Provided are a heater supporter and an electric hob including the heater supporter. A tube heater is supported by the heater supporter, and at least a portion of the heater supporter is formed of a ceramic containing material. Therefore, food can be cooked more rapidly, and the tube heater can be easily installed. Furthermore, damages caused by heat generated from the tube heater can be minimized.
