Description

[Detailed Description of the Invention] The present application relates to a hair dryer that dries hair on the inflow side without blowing hot air.

All conventionally known hair dryers are of the type that dry the hair by blowing hot air, which not only causes discomfort to the user, but also tends to blow hot air at a high temperature. There is a risk of damaging the hair or causing damage to the skin on the head, and this risk is particularly significant when the hot air is switched to a high temperature. There was also the inconvenience of using the device in that the proximity distance between the head and the head had to be adjusted.

Therefore, the purpose of the present application is to eliminate such conventional inconveniences, and an embodiment thereof will be described in detail with reference to the drawings below.
and an air blowing chamber 1a that houses a fan 3 rotated by the motor 2, a hand-held part 1b that houses a heat source 4 in the middle, and an outflow part that houses an air pipe 5 that sends warm air toward the rear in the upper part. The fan 3 consists of a cylindrical body 3a with one end closed and the other open, and a large number of blades 3b, cut and raised around the outer periphery of the cylindrical body 3a. 3b, . . . are provided. The motor 2 is housed inside the cylindrical body 3a, and its rotating shaft 2' is fixed to the center of the closed end surface of the cylindrical body 3a via a fixture 6. In this way, the motor 2 is attached to the fan 3. After the motor 2 is housed in the ventilation chamber 1a of the case body 1 in a state where it is integrally attached, the motor 2 is fixed, for example, via a fastener or an adhesive 7. The heat source 4 is constructed by winding a heater 10 around a bobbin 9, which is made by bonding insulating plates in a cross shape with flanges 8 at the upper and lower ends. It is mounted inside the handheld portion 1b. The hand-held portion 1b has a double wall on the rear side consisting of an inner wall 12 and an outer wall 13, and the inner and outer walls 12 and 1
A space 14 is formed between the outer wall 3 and the outer wall 3 to accommodate wiring, etc. A switch 15 for switching between low temperature air, high temperature air, cold air, etc. is provided in the middle of the outer wall 13, and a power cord is provided on the lower surface of the outer wall 3. 16 is installed. The outflow portion 1c of the case body 1 is connected to the handheld portion 1.
It has a cylindrical shape extending in a direction perpendicular to b and has a closed rear surface and an open front surface, and the edge of the front surface opening is bent inward in a U-shape. Further, a hole 17 is formed on the rear surface, and a curved portion 18 at the front end is provided in the outflow portion 1c.
The air supply pipe 5 is installed concentrically so that the rear end thereof penetrates the hole 17 and protrudes rearward, and a gap is created between it and the inner circumferential surface of the outflow portion 1c. ing. 19 is an air inlet hole formed on the lower surface of the ventilation chamber 1a of the case body 1, 20 is a protective resistor, and 21 is a thermostat.
5 and is connected to the power cord 16. 22
In order to more reliably cut off heat conduction from the heat source 4 to the handheld portion 1b, the handheld portion 1 is attached to the case body 1.
An auxiliary member is provided to cover the front surface of the outflow portion 1c and to surround the outer periphery of the front end portion of the outflow portion 1c, and has a through hole 24 that communicates with a flow path 23 formed in the front portion of the case body 1. It is opened in a part of the lower ventilation chamber 1a of the case body 1.

When the motor 2 is rotated via the changeover switch 15, the fan 3 also rotates, and the outside air is sent to the heat source 4 through the air intake hole 19, where it is heated, and then transferred to the outflow section 1c. After passing through the gap with the trachea 5 and the curved portion 18 of the outflow portion 1c and being directed toward the front end surface of the air pipe 5, the hot air is discharged from the rear end of the air pipe 5.

On the other hand, the outside air from the ventilation chamber 1a reaches the upper part through the flow passage 23, and the air flowing out to the opening 22' is guided by the flow of the warm air and discharged to the outside air through the air supply pipe 5.

In use, when the auxiliary member 22 has the upper opening 22' or does not have the auxiliary member 22, the head is held while lightly pressing the curved portion 18 of the upper outflow portion 1c of the case body 1 against the head. Rub the surface. Then, the water droplets adhering to the hair in the pressed area are evaporated by the hot air, and the evaporated moisture is released from the air pipe 5 along with the flow of the warm air. It is discharged from 5. It goes without saying that by using the hot air discharged from the air pipe 5, it is possible to use the dryer in the same manner as a conventional dryer.

As described above, according to the present application, it is possible to dry the hair without blowing hot air as in the past, so there is no risk of damaging the hair or causing any skin problems, and the case body can be used to dry the hair without blowing hot air. It is convenient to use because it can be used while being pressed lightly against the skin, and it also has the advantage of eliminating discomfort caused by hot air being blown onto it.
