Description

hair dryer {HAIR DRIER}

Embodiments disclosed herein relate to a dryer, and more particularly, to a hair dryer for drying hair by forcibly blowing air.

In general, a hair dryer has a hot air function that when an internal blowing fan operates, an appropriate amount of air is sucked into the inside through an air suction hole formed at the rear of the hair dryer, and the sucked air passes through a heater and discharges the heated heat to the outside. And, it has a cold air function that discharges the air sucked into the intake hole by the operation of the blower fan in a state where the heater is not operated. These hot and cold air functions are divided into strong and weak again depending on the product. has been

Such a hair dryer is mainly used to dry hair at home or to apply a transformation to a desired hair style at a hairdressing salon.

Here, the conventional hair dryer has a structure in which the air outlet is formed in the front of the housing in the longitudinal direction and the intake port is formed in the rear in the longitudinal direction of the housing, so that the flow path of the air is formed in a straight line.

The conventional hair dryer has a structural limitation in that the air flow path is formed in a straight line, so that the length of the housing is relatively long and the straight flow path must be formed.

In addition, since a conventional hair dryer has to be used with one hand, there is a limitation in using both hands, and there is a problem that fatigue and pain occur in the arm when used for a long time.

As a related prior art, looking at the hair dryer having a hair cleaning function presented in Korean Patent Publication No. 10-0833885, an air suction hole is formed in the rear of the hair dryer body and a vent is formed in the front of the main body to form a straight flow path. is composed of

In addition, the prior art has a configuration in which the handle of the dryer must be gripped and used, so there is a limitation that both hands are not freely used.

Accordingly, a new technique for overcoming the limitations of the prior art as described above is required.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .

In the embodiments disclosed in this specification, the length of the dry housing is relatively short by forming the air flow path in a U-turn type rather than a straight line by forming an inflow direction of air flowing into the dry housing and an air discharge direction in the same direction. An object of the present invention is to present a hair dryer that can be formed.

In addition, the embodiments disclosed in the present specification provide a hair dryer capable of introducing external air through one-way rotation of only one fan unit and at the same time U-turning the introduced air into a blowing path.

In addition, the embodiments disclosed herein have an object to provide a hair dryer that can be used wirelessly without a power cable and free movement of both hands by allowing the dry housing to be mounted at a predetermined angle.

As a technical means for achieving the above-described technical problem, according to an embodiment of the hair dryer, a dry housing formed to be gripped, formed to be gripped, and provided with a switch for operation control; a fan unit built in the dry housing and rotating by the operation of a driving motor operated under the control of the switch; an intake passage formed in the dry housing to introduce external air into the dry housing through the rotational force of the fan unit; a blower passage formed in the dry housing to discharge the air introduced into the intake passage, the air passage being formed in a shape that surrounds the outer periphery of the intake passage; and a cavity formed in the dry housing to form an installation space of the fan unit and to communicate the air introduced into the intake flow path to the blowing flow path.

In addition, the intake flow passage extends along the longitudinal direction of the central axis of the dry housing, and the blow passage is formed to form an annular cross section that is coaxial with the intake flow passage and surrounds the outer circumference of the intake flow passage. It can be extended parallel to the euro.

In addition, the fan unit is formed in an annular shape corresponding to the cross section of the air flow passage, and a plurality of blow blades having a predetermined inclination are provided along the circumferential direction and disposed at the inlet end of the air flow passage, and to the drive motor and a blower fan which forms a negative pressure in the cavity while forcibly supplying air from the cavity to the blowing path through rotation of the air flow path to introduce air from the intake path into the cavity.

In addition, the fan unit is formed in a shape corresponding to the cross-section of the intake passage and is disposed at the end of the outlet side of the intake passage, and a plurality of intake blades having an inclination opposite to that of the ventilation blades of the blowing fan are radially formed. It may further include an intake fan that is provided and forcibly supplies air from the intake flow path to the cavity while providing suction force to the intake flow path through rotation by the driving motor.

In addition, the blower fan may be formed as a body along the outer circumference of the intake fan while being coaxial with the intake fan to rotate together.

In addition, the cavity is formed in the form of a container for accommodating the outlet end of the intake passage and the inlet end of the air passage among longitudinal ends of the intake passage and the air passage to block the air discharged from the intake passage. While making a U-turn in the outward direction, it is possible to guide the airflow passage.

In addition, the hair dryer may further include a holder for mounting the dry housing at a predetermined angle while being detachably coupled to the dry housing.

In addition, the cradle, a base that provides support while being placed on the floor; and a post installed on the base, extending in the vertical direction, and providing a coupling portion of the dry housing.

In addition, the post may be formed in a telescopic cylinder structure so that the length can be adjusted.

In addition, the post may be rotatably coupled to the lower end of the base to enable angle adjustment of the dry housing.

According to any one of the above-mentioned problem solving means, the air flow path is formed in a shape surrounding the intake flow path, and the air flow path is formed in a U-turn type rather than a straight line, so that the length of the dry housing can be relatively short. can present

In addition, since the air blowing passages are formed along the periphery of the intake passages and open in the same direction as each other, it is possible to provide a hair dryer in which hair is not easily sucked into the intake passages.

In addition, since the fan unit is composed of a blower fan and forms a negative pressure in the cavity while discharging the air in the cavity to the blowing flow path, it is possible to present a hair dryer in which external air can be smoothly introduced through the intake flow path.

In addition, when an intake fan is added to the fan unit, it is possible to present a hair dryer capable of smoothly introducing air into the cavity and discharged to the blowing passage because it provides suction power to the intake passage.

In addition, when the intake fan and the blowing fan constituting the fan unit are coaxially formed and formed as a single body, a hair dryer capable of sucking air into the intake passage only by rotating the fan unit in one direction, u-turning it to the air passage, and discharging it. can

In addition, since the dry housing can be used by holding the dry housing on the holder at a predetermined angle, you can use both hands freely while grooming your hair. It is possible, so you can expect a more free-to-use effect.
