Hair dryer

Abstract

Disclosed herein is a hair dryer. The hair dryer includes: a body provided in a cylindrical shape having an annular sectional surface, configured to form an air flow path, and provided with one or more air inlets and an air outlet; a blower fan provided between the air inlets and the air outlet, and configured to be rotated to thus introduce external air into the body and blow the external air; and a heating coil provided between the blower fan and the air outlet, and configured to heat the external air; wherein air outside the air flow path is introduced into the air flow path and blown to the user along with the air being blown via the air outlet by means of a difference in air pressure between the inside region of the air flow path and a region outside the air flow path.

AI Technical Summary

Benefits of technology

The present invention aims to solve problems with traditional hair dryers by introducing and blowing external air through the difference in air pressure. This technology can reduce noise and vibration while also achieving the same hair drying effect with less power. Additionally, the invention maintains the inflow path of external air without interference.

Problems solved by technology

However, the conventional hair drying method is designed to draw air in a surrounding space and discharge the drawn air at high speed through a small outlet due to the structure of the hair dryer.

Accordingly, problems arise in that dust in the air is gathered by the suction force of the blower fan and discharged to the head, face, etc. of a user and in that dust, hair, etc. introduced into the air flow path are burned by the heating coil and blown in the form of dust.

There is possibility that foreign materials, such as dust and hair, may be introduced into the heating coil and discharged in the form of fine contaminants, such as ashes, and thus the fine pollutants may affect the hygiene of the hair or the hygiene of the scalp or face.

Accordingly, in order to secure the rotational driving force of the blowing fan, the power consumption of the hair dryer becomes excessively high, and also noise and vibration problems may occur due to the blowing fan rotating at high speed.

Furthermore, the inlet of air to be blown is provided in the grip, and thus a problem arises in that when the hair dryer is used, the inflow path of external air is rarely maintained without interference due to a user's gripping operation.
