Abstract (en)
Disclosed is a heating element of a hair dryer in which heating efficiency is improved, the calorific value is uniform, negative ions and far infrared rays are generated, disadvantages due to power saving and a broken heating wire are prevented, a structure is simplified so that manufacturing and productivity of the hair dryer can be improved. The heating element includes an aluminum inner radiating plate, installed in the front end of the wind discharging passage, and having a plurality of ventilation holes, an aluminum outer radiating plate, installed in the outside of the inner radiating plate to be spaced apart from the inner radiating plate, and having a plurality of ventilations, and a plurality of ceramic heating elements disposed in a space formed between the inner and outer radiating plates and heated by conducted heat from the inner and outer radiating plates to emit negative ions and far infrared rays.
