Abstract

The invention discloses an electromagnetic induction heating electric hair dryer, pertaining to an airflow generation and heating device. The electrical-heating hair dryer in the prior art has problems and defects in the aspects of application environment, energy saving, safety, noise, comfort, etc. A heater of the hair dryer of the invention comprises an electromagnetic induction eddy-flow heating component served as a heat generation component, electromagnetic coils winding outside the heat generation component and an electronic control circuit that is electrically connected with the electromagnetic coils and positioned outside an airflow channel. As the electric hair dryer adopts the electromagnetic induction to heat air, compared with the hair dryer with electrical heating in the prior art, the heating efficiency of the hair dryer of the invention is greatly improved and the heated air can smoothly flow in the airflow channel, thus the power consumption and operating noise of the hair dryer are remarkably reduced; the flowing speed of the airflow and the temperature distribution at the outlet section of the electric hair dryer are more even and the hair dryer is safer and more comfortable and can save more electricity when in use.

Description

technical field

[0001] The invention belongs to an airflow generating and heating device, in particular to a hair dryer which adopts electromagnetic induction heating method to heat the flowing airflow. Background technique

[0002] Existing hair dryer 1A such as image 3 As shown, it is a hair dryer that uses resistance heating to heat the air flowing through it, and it includes:

[0003] a main housing 10A having an air inlet 12A and an air outlet 11A;

[0004] a fan 2A disposed between said air inlet 12A and said air outlet 11A in said main housing 10A;

[0005] an air flow passage 60A, located downstream of the fan 2A, extending toward the air outlet 11A in the main housing 10A;

[0006] An electric heater 3A arranged in the airflow channel 60A, the electric heater 3A is formed by a resistance wire 4A wound in a helical form on a central support 31A made of a mica sheet.

[0007] The hair dryer with the above structure uses resistance heating to heat the air flowing t...
