Abstract
The utility model relates to the field of electric heating and heat conduction technology, specifically to a heating structure and the heating device applying it. The heating structure comprises surface layer sequentially stacked and connected, heat-conducting insulating layer, heating film and thermal insulation layer. The heat generating film comprises an electrically conductive layer, and electrically conductive members provided at two end portions of an upper surface of the electrically conductive layer. The heating structure has a high heating temperature, desirable heating uniformity, which can be connected to broad range of voltages. They can be used to adjust heating temperature, and the heating temperature can reach a maximum of 350° C. In addition, the heating structure has the advantages of thin thickness and small volume. The heating device can be used as grill pan, electric hot pot, iron, electric heater, industrial oven or tunnel oven.
