Flush-Mounted Gas Hob Heat Shield for Sensitive Worktops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat-sensitive materials in kitchen environments, such as wooden or plastic workplates, are at risk due to heat radiation and conduction from gas burners, particularly when these burners are flush-mounted, as existing solutions do not adequately address the combined issues of heat radiation and conduction effectively.
Innovation Solution
A reflective shield with a U-shaped profile is positioned adjacent to the gas burner, featuring a slit for enhanced air convection and thermal conduction, combined with a heat barrier in the housing to prevent heat transfer into the workplate, providing comprehensive protection against heat radiation, convection, and conduction.

Engineering Contradiction Analysis
1Shape
If a flush-mounted kitchen hob is used to achieve a seamless appearance, then the aesthetic quality is improved, but heat-sensitive materials are exposed to intense heat radiation and conduction
Solution Approach 1:
A reflective shield is introduced as an intermediary component between the heat source (gas burner) and the heat-sensitive workplate. This shield reflects heat radiation away from the workplate while allowing the kitchen hob to remain flush-mounted, thus maintaining the seamless appearance while protecting the workplate from heat damage
Solution Approach 2:
The protective system is segmented into multiple functional components: a reflective shield for radiation protection, a heat barrier for conduction protection, and a slit for convection management. Each component addresses a specific heat transfer mechanism, allowing comprehensive protection while maintaining the flush-mounted design
2Object-affected harmful factors
If heat protection measures are added to protect heat-sensitive materials, then heat protection is improved, but the device complexity increases
Solution Approach 1:
Multiple protective functions are merged into a single integrated reflective shield component. The shield combines radiation reflection, heat conduction management, and convection control in one element, reducing the number of separate components needed while providing comprehensive heat protection
Solution Approach 2:
The reflective shield serves multiple functions simultaneously: it reflects heat radiation, acts as a thermal barrier, and manages air convection through its integrated slit design. This multi-functionality reduces the need for separate protective components, simplifying the overall structure
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 solution effectively reduces heat exposure to the workplate by reflecting heat radiation, promoting air convection, and facilitating thermal conduction, thereby ensuring the safety of heat-sensitive materials while maintaining a seamless kitchen appearance.
Implementation Method 1
a reflective shield on the side of the heat source is provided to protect the heat-sensitive material from heat radiation emitted from the heat source
Implementation Method 2
a slit is provided between the heat source and the lateral reflective shield in order to promote convectional air movement, thus further improving the cooling situation next to the heat source
Implementation Method 3
a housing of the heat source features a heat barrier to prevent heat conduction from a floor area of the housing into the sidewalls of the housing

AI summary
The invention discloses an arrangement for heat protection, a kitchen hob and a method for heat protection. Characteristically it is particularly suitable for a flush-mounted gas burner (115) and to protect a workplate (105) made of heat-sensitive material from the heat emanated from the flush-mounted gas burner. Three thermal effects are used to protect the heat-sensitive material (105), i.e. thermal conduction (5410), thermal convection (5650) and heat reflection (5350). A U-shaped profile (3200) located adjacent to the housing (4025) of the kitchen hob and to the cutout of the workplate allows to direct an air stream towards the gas burners (115, 5150, 5120, 5130, 5140) to improve the combustion as well as to provide cooling to the cutout. Accordingly, a normal industry standardized cutout may be used for a flush-mounted kitchen hob.
