Problems solved by technology
[0003] For the current hair dryer, the path of the air flow in the ventilation channel of the casing passing through the heating wire is shown as follows: Figure 4 As shown, the air directly passes through the heating wire 2 in the direction of the straight arrow. During this process, since the heating wire is only close to the inner wall of the air duct, the air flow in the middle part of the air duct cannot be heated in time, and the air flow The heating distance of the hair dryer is short and the heating surface is small, so the air heating effect of the hair dryer is not good.

The invention provides a high-heat hair drier and belongs to household electrical equipment. The high-heat hair drier comprises a shell, a fan and 2-4 circles of electric heating wires, wherein the electric heating wires are connected with a power supply structure; each electric heating wire is fixed on a round insulation heat-conducting plate; the heat-conducting plates are sequentially fixed in a ventilation duct of the shell from front to back so as to seal the ventilation duct; each heat-conducting plate is also provided with a circle of ventilation holes, and the ventilation holes on every two adjacent heat-conducting plates are formed at different sides of the electric heating wire; and the fan is arranged in front of the heat-conducting plates. The high-heat hair drier can provide a long and wide heating path and a long and wide heating surface for airflow in the shell, so that the airflow can be fully heated while flowing through the hair drier, thereby generating high-heat airflow.
Description
Technical field [0001] The invention relates to a household electrical equipment, in particular to an electric hair dryer, which comprises a casing, an electric heating wire and a fan. Background technique [0002] Hair dryer is a commonly used household electrical equipment, mainly used to dry hair; the current hair dryer is mainly composed of a shell, heating wire, and a fan. The heating wire and fan are arranged inside the shell. The heating wire has multiple sections, each section The heating wire is fixed in the ventilation duct of the casing in a loop shape, and the fan is arranged behind each heating wire. When the hair dryer is energized, the heating wire generates heat, and the fan blows cold air into the ventilation duct of the casing from the rear. It is heated by each section of the electric heating wire and blown out from the ventilation duct to dry the hair. Therefore, under the same power, the higher the temperature of the air blown by the hair dryer, the better th...
