More Information
Summary:The utility model relates to a heating disk for electric heating kettles, comprising an internal reflection surface and an external reflection surface that present paraboloid shapes and are fixedly connected with the bottom of a kettle. The void between the bottom of a kettle and the internal reflection surface is an actual effect layer that presents a negative pressure state, the void between the internal reflection surface and the external reflection surface is a vacuum layer, and the inner part of the actual effect layer is provided with heating wires. The dual-layer heating disk has low heat energy loss and high thermal efficiency.
