Dual hotplate for glass ceramic hub - has extra heater between two normal circular heaters to heat long dishes evenly

摘要

The dual hotplate has two spaced circular heating components with electrical heating elements. An extra heating component (3) is located between the adjacent circular heating components (1,2) and has two mirror-image circular side faces (4,5) matching the curvatures of the circular heating components. A gap (7,8) may separate the extra heating component from the two circular components or the components may touch with no gap. The extra heating component extends across the diameter of the circular heating component.
