Technical Field

[0001] The utility model relates to the technical field of electric heaters, in particular to an electric heater used for boiling water or keeping warm. Background Art

[0002] The electric heater involved in this patent includes a shell, a core assembly and a panel. The panel is arranged at the upper end of the shell to support the heated object. The core assembly includes a heating plate and an electrical module. The heating plate is arranged on the lower side of the panel. When working, the electrical module controls the heating plate to turn on the power and generate heat.
